TACKLING
THE SPREAD OF MRSA IN
THE
HOME
One of the main concerns highlighted by new research from the
International
scientific forum, IFH, commissioned by Domestos, is the potential for
transfer
of aggressive strains of community acquired MRSA into hospitals.
It
seems that nearly half of all respondents surveyed were not aware that
it
is possible to pick up infections such as MRSA unwittingly in the
community.
Although statistically the risks are quite low, good hygiene in the
home
can help minimise risk. The full IFH report can be found at http://www.ifh-homehygiene.org/2003/2library/MRSA_expert_report.pdf.
SEX EDUCATION NOT WORKING?
An editorial in the BMJ – 20tth January 2007 - despite increasing
provision
of school sex education, teenage sexual health in the United Kingdom is
in
overall decline. Increasing rates of terminations and sexually
transmitted
infections in under 18s outweigh recent modest reductions in conception
rates
in this age group.
Research seems to indicate that rather than improving sexual health,
sex
behaviour interventions can make it worse. It seems that most
studies
on sex education programmes in schools examine intermediate outcomes
only,
such as pupil satisfaction or reported condom use. This often
facilitates
premature false claims of success, whereas more robust outcome measures
such
as rates of terminations, unplanned conceptions, and sexually
transmitted
infections show no benefit.
The author cites research also published in the BMJ - 20th January 2007
–
which reports the effect of theoretically based teacher delivered sex
education
programme (SHARE) on registered conceptions and terminations. The
trial
found no significant difference between the intervention and control
groups.http://www.bmj.com/cgi/content/abstract/334/7585/133
DELAYING TYMPANOSTOMY TUBES
DOES NOT
HARM CHILDREN
Delaying insertion of tympanostomy tubes in children with persistent
middle-ear
effusion does not affect their cognitive development measured at age 9
to
11, according to a randomized study in the New England Journal of
Medicine
(January 18th 2007.)
The study included almost 400 children who had persistent middle-ear
effusion
before age 3. Most had also scored abnormally on at least one hearing
test.
Tympanostomy tubes were inserted promptly after criteria for persistent
effusion
were met in about half of the children; for the other children,
insertion
was delayed for 6 or 9 months. At age 9 to 11, the groups scored no
differently
on evaluations of literacy, attention, academic achievement, or social
skills.
Previous reports from the same study found that prompt tube insertion
did
not improve developmental measures at ages 3, 4, or 6.
An author concludes that there is now "convincing evidence that
persistent
middle-ear effusion in otherwise normal children does not cause
developmental
impairments." http://content.nejm.org/cgi/content/short/356/3/248
PANDEMIC INFLUENZA MAY KILL 62
MILLION
A YEAR
According to a report in THE LANCET – 23rd December 2006 – researchers
predict
that 62 million people—96% from the developing world—could die in a
year
if a pandemic similar to that of 1918- 20 were to occur today.
Potential
mortality from a major influenza pandemic have varied from 2 million to
360
million and even up to 1 billion. However, these estimates have been
based
on historical accounts rather than quantitative data. In the
latest
US study, death registration data has been used to calculate excess
mortality
during the 1918–20 pandemic in 27 countries.
When they extrapolated the 1918–20 mortality rates to the worldwide
population
of 2004, they found that 51–81 million individuals could die if a
similar
pandemic were to occur that year. They found that people on
high-incomes
were less likely to die in a pandemic than poor people. Death rates
varied
by 30-fold across countries and income per head could explain half this
variation.
The researchers conclude that, irrespective of the lethality of the
virus,
the burden of the next influenza pandemic will be overwhelmingly
focused
in the developing world.

INHERITED ISCHAEMIC STROKE MORE COMMON IN WOMEN THAN MEN
More women than men inherit ischaemic stroke, irrespective of
traditional
vascular risk
factors, according to an article published online (Friday
December
22, 2006) by THE LANCET NEUROLOGY. UK researchers assessed the
relation
between the sex of patients who had an ischaemic stroke or transient
ischaemic
attack and history of stroke in their mothers, fathers, and
siblings.
They used data reported in the population-based Oxford Vascular Study
(OXVASC),
which assessed all incident or recurrent transient ischaemic attacks
and
strokes in a population of 91106 people registered with 63 family
physicians
in Oxfordshire, UK. Their findings show that the identification of a
family
history of stroke in a female first-degree relative is an important
clinical
indicator of an increased risk of stroke in women and the likely age at
first
stroke.

COGNITIVE TRAINING MAY AID FUNCTIONING OF OLDER ADULTS
Cognitive training not only can delay cognitive decline in older
adults,
it may also help them function independently longer, according to a
report
in JAMA – 20TH December 2006. Researchers randomized 2832 people age 65
or
older without dementia to receive either 10 weekly sessions of training
in
one of three domains (memory, reasoning, or processing speed) or no
training.
All trained groups had less subsequent decline in the domain trained
than
did the other groups. Those with reasoning training also retained more
of
their abilities in instrumental activities of daily living. http://jama.ama-assn.org/cgi/content/full/296/23/2805
BLACK COHOSH & OTHER BOTANICALS DO NOT STOP MENOPAUSE SYMPTOMS
Black cohosh, alone or with other botanicals, does not relieve hot
flushes,
according to a randomized, placebo-controlled, double-blind study in
ANNALS
OF INTERNAL MEDICINE – 19th December 2006. Researchers assigned some
350
menopausal and postmenopausal women aged 45 to 55 to a year of
treatment with
black cohosh alone; a multibotanical supplement including black cohosh,
with
or without counseling for a high-soy diet; estrogen with or without
progesterone;
or placebo. Before treatment, all women had at least two hot flushes or
night
sweats daily. Symptoms dropped off in all five groups over the course
of
the trial, but only hormone therapy was significantly more effective
than
placebo. http://www.annals.org/cgi/content/full/145/12/869
SHOULD
BABIES
BE LEFT TO SLEEP IN INFANT CAR SAFETY SEATS?
Young infants should not be left unattended to sleep in standard car
safety
seats as they may be at risk of hypoxia according to research published
in
The BMJ – 9th December 2006. 43 consecutive infants were examined
who
had presented after an acute life threatening event. It was found that
nine
had been asleep in such seats at the time of a perceived change in
colour
and breathing. All infants seemed otherwise healthy. Car seats may
cause forward
flexion of the neck and lead to impaired airway function and oxygen
desaturation.

NEW YORK CITY IS FIRST TO BAN TRANS FATS IN RESTAURANTS
New York is the first city to ban industrially produced trans fats from
restaurant
food. The city health department now requires restaurants to stop
using
the trans fats for most frying or in spreads by July 1, 2007. They will
have
an extra year to eliminate them from all other foods, as well as from,
in
the words of the regulation, "oils or shortenings used for deep frying
of
yeast dough or cake batter."
In explaining the ban, the health department says: "Because an
estimated
one third of dietary trans fat comes from foods purchased in
restaurants,
the continued presence of partially hydrogenated vegetable oils in
restaurant
foods represents an important contribution to cardiovascular risk for
New
York City diners."
OCCUPATIONAL THERAPY FOR DEMENTIA IMPROVES FUNCTION
Community based occupational therapy for elderly patients with dementia
improves
daily function and reduces the burden on carers (See BMJ 9th December
2006.)
One hundred and thirty five people over 65 with mild to moderate
dementia
were randomised to receive 10 sessions of occupational therapy,
including
cognitive and behavioural interventions, over five weeks or no
additional
treatment. The positive effect of treatment remained significant seven
weeks
after the intervention ended despite patients' limited learning
abilities.
The number needed to treat for a clinical improvement was 1.3.

COLSTRIDIUM DIFFICILE MORE
VIRULENT
The American journal, Annals of Medicine – 21st November 2006 –
publishes
a narrative review of Clostridium difficile-associated disease (CDAD),
particularly
relating to the recent increase in cases seen across the world. The
author
briefly describes the history of CDAD: antibiotic-associated colitis
was
recognised soon after antibiotics became available and was initially
thought
to be due to Staph. aureus, however C. difficile was established as the
main
cause around 30 years ago. Initially it was associated mostly with
clindamycin,
however cephalosporins soon took over as the main precipitant, and many
cases
are now associated with fluoroquinolone use.
The strain currently in circulation appears to be more virulent than in
the
past, and is more difficult to treat. Nevertheless, the basic
principles
of management are unchanged, and the author emphasizes the need for
better
diagnostics, early recognition, improved methods to manage severe
disease
and relapsing disease, and greater attention to infection control and
antibiotic
restraint.

SMOKING MAY INCREASE HPV-ASSOCIATED CERVICAL CANCER RISK
Smoking may dramatically increase the risk conferred by HPV-16 for
developing
cervical cancer in situ (CIS), according to a Swedish study published
in Cancer Epidemiology Biomarkers & Prevention. – November
2006. Using the Swedish cancer registry and archival pap smears,
researchers
identified 375 women diagnosed with CIS and matched them with a similar
number
of controls. For both cases and controls, the study included only those
women
whose first smear during the 25-year study period was cytologically
normal.
Women who were HPV-16 positive and smoked at the time of their first
smear
had an adjusted odds ratio for CIS of 14.4, compared to HPV-16 negative
smokers.
Among nonsmokers, the adjusted odds ratio was 5.6, comparing HPV-16
positive
to HPV-16 negative women. http://cebp.aacrjournals.org/cgi/content/abstract/1055-9965.EPI-06-0399v1
LATEST UK STATISTICS FOR HIV, AIDS
A report from the Health Protection Agency – A Complex Picture
-
contains the most up-to-date description of HIV, AIDS and sexually
transmitted
infections in the UK. The report, which has been released for World
Aids
Day, estimates that 63,500 adults are now living with HIV in the
UK.
Commenting on the figures, the fpa (Family Planning Association) has
called
upon primary care trusts to make sure that money dedicated to sexual
health
actually reaches front line services and not diverted to fill out other
fund
deficits.

ALTERNATIVE HOPE FOR EARLY
STAGE
ALZHEIMER’S DISEASE
New German research suggests that natural supplements may help in the
very
early stages of the disease. According to lead researcher Prof
Gunter
Siegel, an in vitro study has shown that omega-3 fish oil and ginkgo
biloba
may delay mental deterioration by inhibiting degenerative processes in
the
brain. The combination has apparently succeeded in cutting
the
formation of early deposits, or ‘nanoplaques’, in the brain by more
than
10% and their size reduced by almost 15% compared with controls.
Explaining the thinking behind the research, Professor Siegel said “One
of
the hallmarks of Alzheimer’s disease is the accumulation of
amyloid-containing
plaques in the brain. We know that fish oils are heart protective
and
that amyloid plaques are very similar in composition to atherosclerotic
plaques
found in the arteries of people with heart disease.”
Using a patented process originally designed to investigate
atherosclerotic
nanoplaques in coronary arteries, the team simulated the formation of
amyloid
plaques by bringing together the molecules responsible for plaque
formation.
In addition to β-amyloid, this process involves cholesterol
(particularly
oxidised or modified cholesterol), a receptor protein and
calcium.
The formation was measured in the absence and in the presence of
omega-3
fish oil and ginkgo biloba using a baser-based spectroscopical method.
Comments Professor Siegel: “Although our findings need to be
confirmed,
we can conclude from these biosensor assay experiments that the binding
to
the receptor protein of the molecules responsible for the initiation of
nanoplaque
formation is inhibited. This indicates that amyloid plaque
formation
is slowed down. It appears that ginkgo biloba’s antioxidant
action
is involved which reduces the level of the oxidised cholesterol
particles.
This is a brain health benefit in addition to those previously recorded
and
for which ginkgo biloba is so widely used in Germany.”
He concludes: “The results are quite clear but do need to
be
confirmed in a clinical trial.” Professor Siegel is now
recruiting
patients whose cholesterol profile puts them at higher risk of
Alzheimer’s
disease. Please click

PHYSICAL ACTIVITY DOES NOT ALTER CHILDREN'S BMI
According to a report in the BMJ – 18-11-2006 - A physical activity
intervention
designed to prevent obesity in children did not alter body mass index
or
sedentary behaviour, according to new research. The authors randomised
545
preschool children either to follow an exercise programme at nursery
and
at home or to no extra activity. Follow-up at six and 12 months showed
that
the exercise programme improved children's motor skills, which may
affect
future participation in sport, but had little effect on obesity in the
short
term. Please click

STUDY SUGGESTS A ROLE FOR LUNG
CANCER
SCREENING
A large, uncontrolled, prospective study of annual lung-cancer
screening
using spiral CT suggests that the technique detects the disease when it
is
largely curable, but questions remain about the utility of this
approach
in real-world settings. Researchers used spiral CT to screen some
30,000
asymptomatic people with various risk factors for lung cancer, then
repeated
the screening for most of them within 7 to 18 months. The screenings
detected
lung cancer in almost 500 participants, 85% of whom had stage I
disease.
Based on a median follow-up of 40 months, the researchers estimate that
the
10-year survival rate for participants with stage I cancer was 88%.
Writing in the New England Journal of Medicine, the authors
conclude
that spiral CT screening of people at risk for lung cancer could
prevent
some 80% of deaths from the disease. But an editorial cautions that
"biases
such as lead time and over diagnosis could have been introduced in the
final
analysis of mortality and the question of cost-effectiveness remains
unanswered."

IRON-DEFICIENT INFANTS -- SUFFER COGNITIVELY
Chronic iron deficiency in infancy is associated with cognitive
deficits
that persist into young adulthood, and among poorer children those
deficits
become more pronounced with time, according to research published in
Archives
of Pediatrics and Adolescent Medicine.
The authors enrolled 185 Costa Rican infants between 12 and 23 months
of
age and followed their cognitive status at intervals to age 19. Among
children
of moderate means, researchers found an 8- to 9-point difference
between
iron-deficient and iron-sufficient infants, using a composite score
that
combined various cognitive measures (rescaled to a mean of 100 and a
standard
deviation of 15 to 16). The difference remained stable over time.
Importantly,
in poorer children the gap grew from 10 points in infancy to 25 points
at
age 19.
Given the implications for individuals and society, the authors say "it
seems
reasonable to prevent iron deficiency in infancy and treat it before it
becomes
chronic or severe."

GONORRHOEA GETTING MORE
RESISTANT
TO ANTIBIOTICS
The Health Protection Agency has released new figures showing that
levels
of antibiotic resistance in gonorrhoea are on the increase. The levels
of
resistance to ciprofloxacin have increased from 14% in 2004 to 21.7% in
2005
and to penicillin, from 11.4% in 2004 to 17.9% in 2005.
A researcher with the agency said: “This increasing resistance to
penicillin
and ciprofloxacin is concerning and highlights the need for anyone who
is
infected to be treated with the recommended therapy, ceftriaxone or
cefixime.
The recommendation for treatment with cephalosporin antibiotics was
made
in 2002 when information from this programme showed that resistance was
increasing
to fluoroquinolone antibiotics such as ciprofloxacin. Ceftriaxone or
cefixime
should be used unless laboratory testing has shown that other
antibiotics
such as ciprofloxacin or penicillin will be effective.”
However, it appears that no treatment failures have been documented
with
the recommended cephalosporins, ceftriaxone or cefixime and doctors are
advised
that if patients’ infection does not seem to be clearing up then they
should
submit samples to a laboratory for antibiotic resistance testing.

PEDIATRICS ACADEMY STRESSES BENEFITS OF PLAYTIME
A report of the American Academy of Pediatrics recommends that children
be
given ample time for play that is "child driven rather than adult
directed."
The report notes the trend toward pushing children to take part in
organised
after-school activities. It says that while these can be helpful for
many
youngsters, there is also a risk of leaving too little time for
creative
play. It says healthcare providers should offer the following
guidelines:
- Recommend
that children get "ample, unscheduled, independent, nonscreen time to
be
creative, to reflect and to decompress";
- Discourage
parents from offering computer games and other passive entertainment
and
instead emphasize active play;
- Promote
the benefits of toys like blocks and dolls that allow children to use
their
imaginations;
- Reassure
parents regarding the value of unscheduled time with their children and
remind
them that their love, role modeling, and guidance are more important to
success
than extracurricular commitments.
VITAMIN D SUPPLEMENTATION MAY NOT PREVENT FRACTURES IN ELDERLY
A large controlled trial did not show that vitamin D supplements
reduced
falls or fractures in a group of elderly people in residential
accommodation.
The authors, reporting in the Journal AGE AND AGEING, note that there
is
conflicting evidence on whether or not vitamin D supplementation can
reduce
fractures and falls in the elderly. They therefore carried out a
cluster-randomised
trial in 118 residential homes for the elderly to identify whether
supplementation was effective in this group. The 118 homes included a
total of 223 residential
units, which were taken as the unit of randomisation. Participants were
randomised
to treatment (oral vitamin D as ergocalciferol 2.4mg every three
months)
or control (no additional treatment); primary outcomes were fracture
(reported
by care home staff) and falls (from routinely collected data). Baseline
and
on-treatment serum vitamin D levels were measured in a 1% sample of the
treated
group.
A total of 3,717 residents (76% women, mean age 85 years) agreed to
take
part in the study, of whom 1,762 received vitamin D supplements and
1,955
were controls; median follow-up duration was ten months. There was no
significant
difference between the groups in fractures (3.2% treatment vs. 2.6%
controls
for non-vertebral fracture), or in falls: the proportions reporting at
least
one fall were 44% and 43% respectively. Pre-treatment serum vitamin D
levels
were relatively high, with a median 25-hydroxy vitamin D concentration
of
47 nanomol/l. The authors conclude that in their population, there was
no
evidence that vitamin D supplementation prevents fractures or falls.
They
discuss some possible factors that might be relevant, including the
relatively
high-pre-treatment vitamin D levels in this patient group. An
accompanying
editorial discusses the study

LANCET RECOMMENDS HPV VACCINE
FOR
ALL ADOLESCENTS
An Editorial in THE LANCET - 7th October 2006 - concludes that all
adolescents
should receive the human papilloma virus (HPV) vaccine to maximise its
potential
benefits. It notes that support is growing for such an approach.
Modelling
studies indicate that vaccinating only females would be 25% to 40% less
effective
in reducing HPV prevalence in women than vaccinating all adolescents;
there
are also other manifestations of HPV infection that affect both sexes,
such
as genital warts and anal cancer. There is also the example of the
rubella
vaccination programme in the UK, which originally included females only
but
was extended to include boys because there was a rise in the number of
rubella infections in pregnant women. The editorial concludes that the
trial data involving boys is urgently needed, but long-term eradication
of HPV requires
all adolescents to be immunised. Meanwhile, it says, all EU states
should make it mandatory for 11-12-year old girls.

WEIGHT GAIN BETWEEN PREGNANCIES MAY LEAD TO COMPLICATIONS
Weight gain between pregnancies may lead to complications during
pregnancy
and the delivery period, according to an Article published in THE
LANCET
– 30th September 2006. The study analysed the
interpregnancy
body-mass index (BMI) change between the first two consecutive
pregnancies
in over 150 000 Swedish women, as well as the incidence of maternaland
perinatal*
complications during the second pregnancy. The study found that weight
gain
during the interpregnancy period is strongly associated with major
maternal
and perinatal complications, even in women who are not medically
overweight.
It has been shown that a gain of 3 or more BMI units is associated with
an
increased risk of: pre-eclampsia; gestational hypertension;
estational
diabetes; caesarean delivery; stillbirth and large-for-gestational-age
births.
The paper concluded that: “[The results] provide robust epidemiological
evidence
for advocating weight loss in overweight and obese women who are
planning
to become pregnant, and to prevent weight gain in the larger population
of
women with healthy weight.” http://www.thelancet.com
NEW CANCER DRUG EXTENDS LIFE FOR LUNG CANCER PATIENTS
Lung cancer patients treated with an experimental new drug lived over a
third
longer than patients treated with standard chemotherapy, according to
recent
date (September 2006).
The phase II study, carried out by UK biotech company Antisoma plc,
looked
at 70 patients with non-small cell lung cancer (NSCLC).
Patients treated with AS1404 on top of standard chemotherapy lived over
a third longer (14 months) than patients treated with chemotherapy
alone
(8.8 months). This is claimed to be one of the largest increases
in
life expectancy ever seen in a trial adding a new drug to chemotherapy
in
NSCLC.
Safety data from the trial were also said to be encouraging. The
addition
of AS1404 to chemotherapy was well tolerated.
These findings extend the positive data announced at a major US cancer
conference
in June 2006 (http://www.antisoma.com/investor_relations/documents/ASCO_201_lung.pdf),
which showed increased tumour response rates, longer time to disease
progression
and enhanced survival.
CERVICAL CANCER VACCINE APPROVED
Gardasil, a vaccine that is said to prevent cervical cancer,
pre-cancerous
cervical lesions, pre-cancerous vulval lesions and genital warts has
been
granted a European licence. It targets the four virus types which
together
account for the majority of genital Human papillomavirus diseases types
6,
11, 16 and 18.
In large clinical trials, involving more than 25,000 women, the new
vaccine
prevented up to 100% of cervical cancer, pre-cancerous and potentially
pre-cancerous
cervical lesions, vulval and vaginal pre-cancerous lesions and genital
warts
due to Human Papillomavirus types 6, 11, 16 and 18. Consistent
efficacy
has been reported for up to five years and is expected to be
long-lasting.
It is anticipated that Gardasil will be launched in the UK in the
coming
weeks. The Joint Committee on Vaccination and Immunisation
(JCVI),
the expert committee that advises the Government on vaccine policy, is
currently
reviewing the u se of human papillomavirus vaccines and their potential
benefit.
The JCVI will advise on the possible introduction of routine universal
vaccination,
for example for certain age groups.
In clinical trials, Gardasil is said to have shown 100% efficacy in the
prevention
of pre-cancerous cervical lesions (high grade, CIN2/3) related to Human
Papillomavirus
16 and 18. In the US, experts have recommended the routine
vaccination
of 11-12-year-old girls and the vaccination of 13 to 26-year-olds who
have
not previously been vaccinated.
Gardasil has been developed by Merck & Co Inc and Sanofi Pasteur
MSD. Please click here to

PROSTATE CANCER THERAPY LINKED TO DIABETES AND HEART
DISEASE
Androgen-deprivation therapy for prostate cancer may increase the risk
for
diabetes and heart disease, according to a study published yesterday in
the
JOURNAL OF CLINICAL ONCOLOGY.
The observational study identified 73,196 Medicare enrollees diagnosed
with
locoregional prostate cancer and studied them at a median of 4.55 years
after
diagnosis. Men who took gonadotropin-releasing hormone (GnRH) agonists
had
hazard ratios of 1.44 for incident diabetes, 1.16 for incident coronary
heart
disease, 1.11 for myocardial infarction, and 1.16 for sudden cardiac
death,
compared with men who didn't take GnRH agonists, after adjustment for
numerous
socioeconomic and medical variables. Men treated with orchiectomy had
an
adjusted HR of 1.34 for incident diabetes, but no increased risk for
coronary
heart disease, MI, or sudden cardiac death.
Given the increasing use of hormone therapy for prostate cancer, the
authors
urged physicians to weigh its benefits against potential increased
risks
for diabetes and heart disease. http://www.jco.org/cgi/content/abstract/24/27/4448
DR CHRIS STEELE LAUNCHES WEB SITE
ABD Member, Dr Chris Steele, the resident doctor from ITVs This
Morning,
has launched his own health website – http://www.thefamilygp.com - from which he will conduct
a
weekly
online surgery. The intention is to bring consumers the latest in
health
news and medical information, commentary and products. A range of
innovative
and interactive features are to be incorporated shortly, including
videos
of self-examination techniques, and surgical procedures.
RCOG REPORT ON ALTERNATIVE THERAPIES
A report from the Royal College of Obstetricians and Gynaecologists
(RCOG)
examines the use of alternative therapies for symptoms of the
menopause.
It notes that there is often little to no evidence on the safety and
efficacy
of these treatments and examines the evidence that is available.
The
report highlights some dangers but notes that alternative treatments
for
menopausal symptoms achieve about 50-60% symptom reduction (compared to
80-90%
with HRT). Some, such as red clover and soy, may also have beneficial
effects
on the skeleton and cardiovascular system. Further research is needed
to
determine long-term efficacy and safety. It recommends that each woman
should
be assessed individually, considering the advantages and disadvantages
of
both alternative and conventional therapies. For PDF of full

NATIONAL GYNAECOLOGICAL CANCER AWARENESS CAMPAIGN
LAUNCHED
The first national campaign to raise awareness of cancers which kill
almost
7,500 women per year takes place from 18 – 22 September 2006.
Every
year over 17,000 women are diagnosed with one of the four main
gynaecological
cancers; ovarian, cervical, endometrial and vulval. Stigma
and
embarrassment still surround these cancers, which can lead to a delay
in
women going to the doctor. Any delay to diagnosis can lead to
significantly
worse survival rates compared to women who were treated earlier. Called
the
Venus Appeal, the campaign aims to encourage women to be more aware of
the
four main gynaecological cancers, and to consult their GP if they have
any
concerns.
Lucy Smith and colleagues from the University of Southampton
investigated
why people delay going to the doctor when they have symptoms of
cancer.
Writing in a recent paper in THE LANCET they report: “Fear of
embarrassment
was related to the discussion of sensitive or sexual areas of the body
and
invasiveness of physical examinations. Such fears were not
reported
in studies of women with breast cancer.” Venus Appeal posters and
leaflets
are being made available through doctor’s surgeries and online at http://www.venusappeal.org
DRUG COULD PREVENT TYPE 2 DIABETES IN HIGH-RISK
INDIVIDUALS
Giving people at high-risk of developing type 2 diabetes a drug called
rosiglitazone,
along with lifestyle recommendations, could substantially reduce their
chances
of developing the disease, according to an Online/Article published by
THE
LANCET - Friday September 15, 2006. In the DREAM trial, Canadian
investigators
randomised 5269 adults with impaired glucose tolerance or impaired
fasting
glucose to receive rosiglitazone or placebo daily for three years. At
regular
intervals throughout the study the researchers emphasised the
importance
of a healthy diet and lifestyle to the participants. They found that
280
individuals on rosiglitazone and 658 on placebo developed diabetes.
There
was a small excess risk of non-fatal heart failure in the drug group
when
compared to the placebo group. The authors conclude: “The results
of
this study suggest that the addition of rosiglitazone to basic
lifestyle recommendations substantially reduces the risk of developing
diabetes by about two-thirds, offering a novel preventive approach.
Balancing both the benefits and the risks suggests that for every 1000
people treated with rosiglitazone for 3
years, about 144 cases of diabetes will be prevented, with an excess of
four
to five cases of congestive heart failure.”

VACCINE COULD CUT CERVICAL
CANCER
DEATHS AND CASES BY 75%
A vaccine against two strains of the human papillomavirus (HPV) could
cut
the number of cases and deaths from cervical cancer by three-quarters,
according
to a new study sponsored by GlaxoSmithKline (GSK). It was
presented
on September 4th at The International Papillomavirus Conference in
Prague
(September 1-7 2006). The study suggests that with
100%
coverage, the vaccine could lead to a 76% reduction in cases of
cervical
cancer and a similar reduction in deaths. These estimated
benefits
are in addition to the lives that are already being saved by the UK’s
existing
cervical screening programme.
A computer model was used in the study to predict the outcome of
vaccinating
all 12-year-old girls in the United Kingdom (376,385 girls) over their
lifetime.
By extrapolating the decrease in cervical cancer cases and deaths seen
in
the study across the entire UK population, the research indicates that
262
women would die each year from cervical cancer, where currently there
are
1,093 deaths. The number of cases of the disease in the UK would also
drop
from 2,841 to 682, according to the new research. However,
because
100% coverage with the vaccine assumed in the study is unrealistic, the
computer
model gives alternatives. With 80% of 12 year old girls vaccinated,
cancer
cases and deaths are predicted to drop by around 61%.
The study also examined the potential impact of vaccination on the
precancerous
stages of cervical disease. Over the lifetime of women vaccinated
at
12 years of age, vaccination is predicted to reduce the burden of
abnormal
smears due to cancer-causing HPV by over half (52.4%) and the
subsequent
need for diagnostic colposcopies by 54.8%.
Vaccination is also predicted to bring a 70% reduction in the more
severe
pre-cancerous stages of cervical disease due to cancer-causing HPV
strains
- Cervical Intraepithelial Neoplasia, CIN 2 and 3). This research
examined
the long-term impact of HPV vaccination using GSK’s candidate HPV
vaccine
which targets HPV 16 and 18, the two most common HPV strains associated
with
cervical cancer. Protection against additional cancer-causing strains
of
HPV was also included in the model.
This inclusion was based on preliminary evidence from GSK clinical
trials,
showing that the candidate HPV vaccine demonstrates additional
protection
against infection with the third and fourth most common HPV strains
associated
with cervical cancer globally, HPV 45 and 31.
Researchers believe that the public health benefits of vaccination may
be
greater than predicted by the study since it does not look at cancers
caused
by HPV that affect other parts of the body. There is evidence
that
HPV 16 and 18 may play a role in causing other anogenital cancers,
including
vulval and vaginal cancers.
Further research is now being carried out to look at the overall
cost-effectiveness
of HPV vaccination to the NHS, which currently spends £157
million
a year in England alone on the cervical cancer screening programme.
Currently
there are still 3,000 women in the UK getting cervical cancer each year
–
despite a highly efficient screening programme. The peak age for
cervical
cancer to strike is while women are in their late-30s, but it can occur
earlier.
Treatments, such as hysterectomy, will prevent them having children,
perhaps
before they have had a chance to start a family. Please click here to email for more

ABOLISH THE TERM ASTHMA SAYS THE LANCET
Asthma is unlikely to be a single disease, so we should abolish the
term
altogether according to an editorial in The Lancet – 26th August
2006.
The word asthma originates from a Greek word that means “to breathe
with
mouth open or to pant.” Asthma includes a range of different symptoms,
such
as wheezing, coughing, and difficulty breathing. The underlying cause
of
asthma is inflammation of the airways, but it is not known what
triggers
this inflammation and why some people develop asthma and others do not.
People
with asthma can have a range of different triggers, symptoms, and
responses
to treatment, and the general consensus now emerging is that asthma is
unlikely
to be a single disease. The author’s view is - “So why wait?
Rather
than confusing scientists, doctors, and patients even further, is it
not
time to step out of the straightjacket of a seemingly unifying name
that
has outlived its usefulness? The conclusion should surely be that it is
best
to abolish the term asthma altogether.” http://www.thelancet.com
STUDY SHOWS BENEFIT OF CHEMOTHERAPY IN LUNG CANCER
According to an online article in THE LANCET ONCOLOGY new results from
the
Adjuvant Navelbine International Trialist Association (ANITA) show that
treatment
with vinorelbine and cisplatin after surgery lengthens survival of
patients
with early-stage lung cancer. “This is the first trial comparing a
third-generation
combination chemotherapy to observation after surgery in totally
resected
patients with all stages of lung cancer”, notes lead author.
Researchers
did a phase III randomised controlled trial in 840 patients with
early-stage,
or non-metastatic, non-small-cell lung cancer. Patients who had had
their
tumours removed surgically were assigned to either observation without
further treatment or to 4 months’ treatment with vinorelbine and
cisplatin.
Survival was found to improve by 8% with the addition of chemotherapy
after
surgery with the majority of the effect seen in patients whose disease
had
spread to the lymph nodes (stage II–III disease), and no effect in
patients
who had tumours measuring 3 cm or larger that had not spread to the
lymph nodes (stage IB).
NICE RECOMMENDATIONS ON
HORMONAL
THERAPIES FOR BREAST CANCER
After considering the feedback from initial consultation, the National
Institute
for Health and Clinical Excellence (NICE) has prepared a Final
Appraisal
Determination (FAD) on the use of hormonal therapies for the adjuvant
treatment
of early oestrogen-receptor-positive breast cancer. The guidance
applies to the use of the aromatase inhibitors anastrozole, exemestane
and letrozole,
within the marketing authorisations for each drug at the time of this
appraisal:
Anastrozole for primary adjuvant therapy
Exemestane for adjuvant therapy following 2–3 years of adjuvant
tamoxifen
therapy
Letrozole for primary adjuvant therapy and extended adjuvant therapy
following
standard tamoxifen therapy
The FAD recommends that choice of treatment should be made after
discussion
between the responsible clinician and the patient about the risks and
benefits
of each option. Factors to consider when making the choice include
whether
she has received tamoxifen before, the licensed indications and
side-effect
profiles of the individual drugs and, in particular, the assessed risk
of
recurrence. http://www.nice.nhs.uk/page.aspx?o=350617
NEONATAL OUTCOMES AFTER
PRENATAL EXPOSURE
TO SSRIS
In utero exposure to the antiepileptic drug (AED) valproate poses a
much
higher risk of foetal death and serious birth defects than the three
other
most commonly used AEDs, suggests a new study published in NEUROLOGY –
08-08-2006.
The Neurodevelopmental Effects of Antiepileptic Drugs (NEAD) study was
originally
designed to assess whether monotherapy with valproate, carbamazepine,
lamotrigine,
or phenytoin was associated with long-term cognitive and behavioural
neurodevelopmental
effects. However, as foetal outcomes were tracked, a high rate of
serious adverse events, including major congenital abnormalities and
foetal death associated with in utero exposure to valproate was
detected, although the
study was not designed to look for these outcomes. The NEAD study is an
ongoing
prospective observational study that includes 25 epilepsy centres in
the
United States and the United Kingdom. From October 1999 to February
2004,
pregnant women with epilepsy who were on monotherapy with 1 of the 4
agents
were enrolled. A total of 323 women and 333 children were included in
the
final analysis of the current report, of whom 110 were taking
carbamazepine,
98 lamotrigine, 56 phenytoin and 69 valproate.
It was found that valproate appeared to produce an incidence of
congenital
malformations of over 17.4%, compared to carbamazepine 4.5%,
lamotrigine
1.0% and phenytoin 7.1%. The incidence of foetal death was not higher
with
valproate (2.9%) compared to carbamazepine (3.6%), lamotrigine (0%) and
phenyotin
(3.6%). The authors conclude that these results combined with several
recent
studies provide strong evidence that valproate poses the highest risk
to
the foetus. http://www.neurology.org/cgi/content/abstract/67/3/407
FPA CALL FOR MORE VARIED CONDOM
SHAPES
AND SIZES
The fpa is launching Sexual Health week with a call for the NHS to
provide
a wider selection of condoms in different sizes and shapes. It is also
asking
health professionals to start tackling some of the embarrassment that
exists
around condom size. Condoms that don’t fit properly are more likely to
tear
or come off, increasing the risk of unplanned pregnancy or sexually
transmitted
infections (STIs). New research shows that 35% of current or past users
of
condoms have experienced a condom splitting or coming off during sex,
but
64% of this group did not know why this had happened or what had gone
wrong
with its use. When questioned, 25% of respondents had no idea that
condoms
come in different lengths and widths. A further 43% agreed that both
men
and women don’t talk about condom sizes because they get embarrassed
talking
about penis size, yet finding the right fit can improve confidence in
the
method. Poor fit can reduce sexual pleasure and contributes to negative
views
of condoms. Click here

IMPOTENCE MAY BE EARLY WARNING OF HEART DISEASE AND DIABETES
Impotence may be an effective early warning sign of heart disease and
diabetes,
particularly in men of normal body mass index (BMI) who would otherwise
not
be considered at risk, new data indicates. The researchers point
out
that early signs of heart disease and diabetes are more often missed in
men
of normal weight than in those who are overweight so erectile
dysfunction
(ED) could be used to alert doctors to wider health problems. The new
study,
published in the Journal of Urology, concludes that ED may provide a
warning
sign and an opportunity for early intervention in men otherwise
considered
at lower risk for cardiovascular disease or diabetes.
COMMUNITY HOSPITALS COST
EFFECTIVE
FOR POST-ACUTE CARE
A community hospital is as cost effective as a district general
hospital
for post-acute care of older people, according to a study published on
bmj.com
21 July 2006. It states that previous health economic studies have been
methodologically
weak and difficult to interpret. This new research compares the cost
effectiveness
of post-acute care at a community hospital and a district general
hospital in Yorkshire. http://bmj.bmjjournals.com/cgi/rapidpdf/bmj.38887.558576.7C
YOUNG PEOPLE NEED MORE EXERCISE
International guidelines need to recommend higher levels of physical
activity
for young people than they currently do in order to lower their risk of
cardiovascular
disease according to a study in THE LANCET - 22nd July 2006.
Currently,
guidelines recommend that young people should participate in physical
activity
of at least moderate intensity for 1 hour per day. However, the
evidence
for this advice comes from studies that may have been biased because
they
relied on children recalling the amount of exercise they do. These
studies have also only looked at single risk factors for cardiovascular
disease.
The new research suggests that children need 30 minutes more exercise –
ie
one and a half hours daily.

DEMENTIA
DRUGS MANUFACTURER CHALLENGES NICE
Eisai Limited, manufacturer of the Alzheimer’s disease treatment
donepezil
(Aricept®), has announced its referral of the Information
Commissioner
to the Parliamentary Ombudsman for failure to address the refusal by
the
National Institute for Health and Clinical Excellence (NICE) to make
public
key calculations behind its proposal to restrict the use of
anti-dementia
medicines. The company states that despite numerous public
statements
about its commitment to openness and transparency, NICE has repeatedly
refused
to make available the new mathematical model it used to reach the
conclusion
that they believe anti-dementia medicines are no longer a
cost-effective
treatment in the early stages of Alzheimer’s disease.
Despite recommending anti-dementia medicines for both mild and moderate
Alzheimer’s
disease in 2001, NICE has now proposed that only patients with moderate
Alzheimer’s
disease be allowed to receive the medicines on the NHS.
This,
the company claims, has led to an outcry from doctors, carers and
patient
groups alike since this means letting people deteriorate from the
‘mild’ stages of the disease to ‘moderate’ before help can be
offered. Please click here to
email for more information.
CHILD IMMUNISATION CHANGES
A letter from the CMO detailing important changes to the childhood
immunisation
programme has been sent out for circulation 13th July 2006. The
following
changes will come into effect from 4th September 2006:
• Pneumococcal vaccine will be introduced to the routine childhood
immunisation
programme, and the schedule for MenC and Hib vaccines will be modified
• A new routine schedule will be introduced which requires an
additional
immunisation visit at 12 months of age
• A pneumococcal vaccine catch-up programme will be carried out for
children
aged under 2 years.

PATIENTS’ GROUPS SHOULD DECLARE
PHARMACEUTICAL
FUNDING
In the interest of full transparency, patients’ groups should declare
all
sources of funding prominently, states an Editorial in this week’s
issue
of THE LANCET - 1st July 2006. Many patients’ groups would not
exist
without funding from the pharmaceutical industry, according to the
commentary,
and those that accept money from pharmaceutical companies have an
obligation
to declare that funding. The editorial highlights the case of the UK
charity, CancerBACUP, who have described the results for trastuzumab
(Herceptin) in
early breast cancer as “impressive”, and the drug itself as a
“breakthrough”, in press releases. However, the charity failed to
disclose in these releases
the fact that the drug’s manufacturer sponsors the charity. In some
releases
CancerBACUP also failed to discuss concerns about the drug’s efficacy,
adverse
events, and cost-effectiveness. The Lancet comments:
“CancerBACUP’s
failure to discuss these concerns and to mention its drug-company
sponsor
in a press release on this topic, undermines the group’s credibility
and
raises the question in whose interest the group works. http://www.thelancet.com
SOCIAL
MARKETING WOULD BOOST EFFECTIVENESS OF HEALTH CAMPAIGN
The Department of Health should adopt slick marketing techniques used
in
advertising to promote public health issues in England, says a report
published
by The National Consumer Council and reported in the BMJ – 1st July
2006.
The report argues that the concept of “social marketing” could help the
government
improve the efficiency of the NHS and achieve many of its goals in
improving
public health. The health department commissioned the council’s
National
Social Marketing Centre to carry out an independent review of the
technique.
The resulting report says that social marketing, when applied
systematically,
can significantly improve the effects and effectiveness of health
promotion. http://bmj.bmjjournals.com/cgi/content/full/333/7557/10
THE ETHICS OF SHARED ELECTRONIC PATIENT RECORDS
The NHS is planning to make patients' health records more easily
accessible
using a network of integrated databases. An editorial in the BMJ
–
1st July 2006 - points out that easier access to medical data from a
single
resource shared by everyone also makes patients vulnerable. Patient
records
contain sensitive private information that can, if not handled
correctly,
harm the patient. Should all citizens by default be included in the new
electronic records service with the possibility to "opt out" if they
prefer, or should
people be asked to "opt in" only if they want to? The Royal College of
General
Practitioners strongly recommends "opt in" with reference to the
ethical
principle of informed, explicit consent, whereas Connecting for Health,
the
agency building the new electronic records service, recommends "opt
out”.

NICE DRAFT GUIDELINES ON CARE
DURING
LABOUR
Draft NICE guidelines, published 23rd June 2006, set
out
recommendations on good quality care during labour. The guidelines
support
choice for women in deciding where to have their baby and set out the
information
they should be given to help them choose. They aim to make birth as
normal
as possible, by reducing unnecessary medical interventions, and as safe
as possible for mother and baby, by making sure that all the risks are
understood
and properly managed.
The draft guidelines set out a three-pronged strategy recommending that:
- Women
should be able to choose where they give birth. To support them
in
this choice they should be given full information about all the risks
and
benefits of all places of birth. This will allow them to make a fully
informed
decision about which setting is right for them and their babies.
- Service
providers, midwives and doctors, and the organisations they work for,
need
to agree robust arrangements to provide appropriate care in all
settings
for birth, within a governing framework. This should include protocols
which
cover what to do if there is cause for concern about the mother or her
baby, or if an emergency arises.
- The
outcomes
for mothers and babies in different settings should be monitored at a
national
level so that the information currently available is improved for the
future.

EXPANDING DEFINITIONS OF
OBESITY MAY
HARM CHILDREN
According to a report in the BMJ – 17th June 2006 – a new and expanded
definition
of childhood overweight and obesity is expected to be established in
the
United States later this year. The news is causing concerns that
many
healthy children may be unnecessarily labeled as having a disease. The
International
Obesity Task Force, set up in the mid-1990s with grants from three drug
companies,
aims to portray obesity as a serious medical condition and to promote
better prevention and management strategies. It has a high media
profile and is
very influential. Two stories – two links: http://bmj.bmjjournals.com/cgi/content/full/332/7555/1412-a

NEW TREATMENT FOR ROTAVIRUS
DIARRHOEA
& GASTROENTERITIS IN CHILDREN
Researchers have found that a three-day course of nitazoxanide can
substantially
reduce the duration of severe dehydrating rotavirus diarrhoea and
gastroenteritis
in children. The results are reported in THE L;ANCET online -Tuesday
June
13, 2006. Around 1 in 40 children younger than 5 years are
hospitalised
every year because of rotavirus diarrhea and world wide the figure is
far
higher, especially in poor countries. In the trials, patients
were
randomly assigned either nitazoxanide or placebo twice a day for three
days. Symptoms cleared after an average of 31 hours in the
nitazoxanide-treated
group compared with an average of 75 hours for the placebo group.

SEXUAL
HEALTH FUNDING SLASHED
According to The British Association of Sexual Health and HIV (Bashh)
at
least 64 genito-urinary medicine (GUM) providers have been forced to
abandon
carefully laid service improvement plans because of the financial
crisis
in the NHS. This is despite a government pledge to plough a much
needed
£300m into the sexual health sector. Colm O’Mahony, GUM
consultant
at the Countess of Chester Foundation Trust Hospital and head of the
media
group at Bashh, said: ‘Two years ago we thought that finally, after 20
years,
this underprivileged, under funded sector was going to be properly
financed.
We’ve been pleased about this for one and a half years – it’s been
greeted
with enthusiasm by all of us, but now we’re told there’ll be no more
ring
fencing and that PCTs are in terrible debt. Sexual health is still a
priority,
but in name only.’ Jamie Hardie, president of the Society of
Sexual
Health Advisers and senior sexual health adviser at Newham General
Hospital’s
busy walk-in GUM department, said he was ‘extremely concerned’ that
current
NHS financial problems meant postponement of chlamydia screening
locally. He said he was worried this was going to be the pattern in
other areas where
chlamydia screening was due to have started. http://www.publichealthnews.com/news/showcontent.asp?id={F9F27BFC-D251-4D94-AAB1-F948C22A60A4

HPA
URGE
TRAVELLERS TO TAKE MALARIA PRECAUTIONS
June 13th 2006. Following 11 deaths from malaria in 2005, the Health
Protection
Agency (HPA) is urging the increasing numbers of travellers taking
summer
holidays in destinations where malaria is prevalent to take precautions
against
contracting this disease. The majority of those who died took either
inappropriate
or no preventive drugs. This highlights the need for increased
awareness
amongst travellers of the importance of taking the right precautions to
protect
themselves against malaria. Approximately 2000 cases are diagnosed in
UK
travellers every year and this trend shows no signs of abating, with
1754
cases of imported malaria reported in UK travellers in 2005.

TOO MANY PEOPLE STILL RISK
SUNBURN
TO GET A TAN
A new initiative to raise awareness of the dangers of over exposure to
summer
sunshine - The At Ri-Sk? Campaign - is launched this month (May 06) by
ABD
Member, Dr Chris Steele, himself a GP and skin cancer sufferer.
Working
in collaboration with key Women’s Institute Federations, the campaign
aims
to educate and encourage partners, family and friends to support each
other
to aid early diagnosis and successful treatment of solar
keratosis.
The survey has revealed a real reluctance to consult doctors about new
marks
which may appear on the skin, with two in five young adults preferring
to
turn to friends for advice first.
Over the past 10 years the incidence of skin cancer has doubled and as
many
as 70,000 people a year are diagnosed with skin cancer. Thousands
more
remain undiagnosed and untreated. Please click here to email for further

social life.
• Migraine affects c 1-in-7 UK adults.
• An untreated migraine can last for up to 72 hours.
• Sufferers compare migraine to, “being hit over the
head
with a sledge hammer.”
• Up to 25 million working/school days are lost each
year
due to migraine.
• Migraines are up to three times more common in
women
than men.
• The class of prescription medicine, triptans, claim
to

FPA HANDBOOK OF SEXUAL HEALTH
IN
PRIMARY CARE
The Family Planning Association (FPA) has launched a second edition of
the
popular ‘handbook of sexual health in primary care’. The handbook is
aimed
specifically at GPs, practice nurses and other professionals delivering
sexual
health services in primary care settings. It is written by experts, all
specialists
in their chosen field in sexual health. The resource gives evidence
based
guidance to practitioners on the best interventions and key messages to
use
in delivering the best standard of care to patients. In addition to
covering
subjects like contraception, abortion, sexually transmitted infections,
pregnancy planning, diagnosing HIV and sexual dysfunction, other
important issues are
addressed.
POOR CHECKS FOR BEDSIDE BLOOD TRANSFUSION PUT PATIENTS
AT
RISK
According to a report in the BMJ – 20-05-06, patients having blood
transfusion
at the bedside continue to be put at risk of getting the wrong blood or
of
delayed management of adverse reactions, through misidentifications and
lack
of observation. These were the conclusions from an audit of 8054
transfusion
episodes from 217 UK hospitals, carried out by the Royal College of
Physicians
and the National Blood Service. This 2005 audit was designed to assess
good practice in identifying patients before bedside blood transfusions
and to
check on progress in reducing risk to patients since the first audit in
2003.
Good practice was defined as compliance with the 1999 British Committee
for
Standards in Haematology guidelines on the administration of blood and
the
more recent Health Service Circular 2002/009: Better Blood Transfusion:
Appropriate
use of Blood. In the new audit, 6% of bed-side blood transfusions were
made
when patients had no identifying wristbands. In 9% of those cases in
which patients had a wristband, key information was missing. Common
reasons for
not wearing a wristband were that the patient was "well known" or that
it was "not day unit policy," says the report. http://bmj.bmjjournals.com/cgi/content/short/332/7551/1171-a?etoc
DEVELOPMENT IMPROVES HEALING OF CRITICALLY DAMAGED BONE
According to a paper in The International Journal of Surgery a
totally
allogeneic graft material is under development that would eliminate the
need
for harvesting bone from patients. In experiments with rabbits in which
critical
size bone defects had been created, the difference in the amount of new
bone
formation between experimental groups was significant. No bone
formed
across the control group. Commenting on the Hong Kong research,
the
author of the paper said: “the significance of this work is to enrich
commercially available bone matrix with an angiogenic mediator that
makes it a potent
bone-forming compound. Angiogensis or new blood vessel formation is
critical
to bone healing and growth. Therefore, whether the patient is young or
old,
a big part of the healing (bone induction) power can be added to the
grafted
material.” http://www.journal-surgery.com
PATIENTS MUST TELL DOCTORS IF THEY USE ALTERNATIVE MEDICINES
The International Journal of Surgery has published
US
research that illustrates a surprisingly high number of patients use
complementary
and alternative medicines (CAM). Analysis of 151 consecutive general
surgical
patients over three months showed that 40% used some form of CAM.
The
author commented: "Surgeons should check for use of alternative medical
treatments,
especially herbal medications, because of potential harmful
interactions
with anesthesia and other treatments." http://www.journal-surgery.com
IN VIVO LAPAROSCOPIC ROBOTICS
Also reported in The International Journal of Surgery is news
of
research in Omaha on robotic laparoscopic surgery that is evolving to
include
in vivo robotic assistants inserted completely within the human body.
The
impetus for the development of this technology is to provide surgeons
with
additional viewpoints and unconstrained manipulators that improve
tissue
manipulation, safety and reduce patient trauma. Currently available
surgical
robotic systems are implemented from outside the body and will
therefore
always be constrained to some degree by the limitations of working
through small incisions. A family of robots has been developed to
provide vision
and task assistance from inside the body. Fixed-base and mobile robots
have
been designed and tested in animal models with much success. Operations
involving
the removal of a gall bladder, prostate or kidney have all been
performed
with the assistance of these robots. These early successful tests show
how
in vivo laparoscopic robotics may be part of the next advancement in
surgical
technology. http://www.journal-surgery.com

BMJ ONLINE TREATMENT ADVICE FOR PATIENTS
The British Medical Journal (BMJ) has launched a new online health
advice
website, called BestTreatments.co.uk with evidence based information
derived
from the BMJ Clinical Evidence series.
The website provides information on symptoms, treatments, questions to
ask
the doctor, and current evidence on medical research for more than 120
different
conditions ranging from long-term disorders such as cancer, back pain
and
depression, to acid reflux, wisdom teeth and infant colic. The site
will
be updated frequently with the most current evidence and will continue
to
expand on the body of information.

GOOGLE HEALTH INFORMATION SITE
Google has launched a healthcare search engine called ‘Google Health.’
It
is part of a larger vertical search product known as Google co-op, a
work
in progress. As one would expect, there is a strong US bias and
currently
there is no facility to limit search to UK sites. Users can examine
results
obtained from this search engine according to drug information, disease
state,
information for doctors and information type.

RASHES IN PREGNANCY - HEALTH PROTECTION AGENCY GUIDELINES
The Health Protection Agency has published advisory web pages providing
an
easily accessible resource for healthcare professionals. It
covers
the management of women who become infected with, or are exposed to, a
communicable disease during pregnancy. It addresses particularly
rubella, parvovirus B19,
and varicella-zoster virus infection, and gives the magnitude and
degrees
of risk to the foetus in terms of outcomes for the gestation at which
maternal
infection occurs. The guidance aims to help decision-making, has no
legal
status, and will be updated as and when new evidence becomes available.

EU CLAMPS DOWN ON SUNSCREEN MISINFORMATION
Sunscreens that make exaggerated claims about the amount of protection
they
give are to be targeted in new European Union (EU) proposals. Concern
has
been raised about users being mislead into staying out in the sun
longer
than they should and increasing the risk of developing skin cancer. In
particular,
the use of words such as 'sunblocker' and boasting "100 per cent
anti-UVA/UVB"
on sunscreen packaging would be banned, as they imply complete
protection
from the sun, which is an impossible claim. There are also worries
about
the current sun protection factor rating system, which experts say only
accounts
for the sunscreen's ability to prevent sunburn, not stop the harmful
carcinogenic
UVA rays.
ELIMINATE TRANS FATTY ACIDS AND REDUCE HEART ATTACKS
By virtually eliminating the amount of trans fatty acids in
industrially
produced food, between 72 000 (6% of the total) and 228 000 (19%) of
coronary
heart events could be averted each year in the United States.
This
is the conclusion of a US and Dutch review study in the NEW ENGLAND
JOURNAL
OF MEDICINE (N Engl J Med 354;1601-13). The amount of trans fats in
packaged
snack foods, bakery products, deep fried fast food, margarine, and
packaged
snacks such as tortilla chips increases consumers’ risk of
cardiovascular
disease, coronary heart disease, and sudden death from cardiac causes,
say
the researchers They go so far as to claim that “The evidence and
the
magnitude of adverse health effects of trans fatty acids are in fact
far
stronger on average than those of food contaminants or pesticide
residues,
which have in some cases received considerable attention.” To view the

EDUCATION
IMPROVES LONG TERM CONTROL OF ECZEMA
Educational programmes targeted at specific age groups of children and
adolescents
improve the control of atopic dermatitis according to new German
research
published in the BMJ - 22nd April 2006. In a randomised controlled
trial
researchers delivered a weekly educational session to parents of
children
aged 3 months to 7 years and 8-12 years and to adolescents aged 13-18.
The
control group received no education. Dermatitis was significantly less
severe
in intervention groups at 12 months. The parents' quality of life also
improved—as
measured by all five quality of life subscales in parents of children
aged
less than 7 years and by three subscales in parents of children aged
8-12
years. http://bmj.bmjjournals.com/cgi/content/full/bmj;332/7547/933
WHY ARE PRETERM BIRTHS RISING WORLD-WIDE?
Preterm birth is a major contributor to neonatal and infant mortality.
Few
interventions have improved outcome, and management remains an
important
challenge in modern obstetrics. A Danish research paper and an
editorial
in the BMJ – 22nd April 2006 indicate that preterm delivery rates are
increasing,
which is a worrying prospect. Preterm deliveries account for fewer than
1
in 10 births but result in 75% of neonatal deaths and most neonatal
intensive
care admissions. Preterm birth has considerable impact on long
term
future health: 1 in 4 survivors born at less than 25 weeks' gestation
have
severe mental or physical disability. Those born at less than 28 weeks
spend
85 times as long in hospital as term babies in the first five years of
life,
with substantial healthcare costs. Even beyond 32 weeks, when
"neurologically
intact" survival is good, educational and behavioural problems occur in
1
in 3 children. For the BMJ editorial click on http://bmj.bmjjournals.com/cgi/content/full/332/7547/924

MOBILE PHONES DO NOT INCREASE
RISK
OF GLIOMA
Mobile phones are not associated with a raised risk of glioma in the
short
or medium term according to a paper in the BMJ – 15-04-06. A case
control
study that included interviews with almost 1000 patients with a glioma
found
an odds ratio of 0.94 (95% confidence interval 0.78 to 1.13) for glioma
for
regular phone users compared with those who never or only occasionally
used
one. Nor was there an association of glioma risk with lifetime years of
use,
cumulative hours of use, or cumulative numbers of calls. http://bmj.bmjjournals.com/cgi/content/full/bmj;332/7546/883
NICE RESPONSE TO APPEAL COURT RULING ON HERCEPTIN
Commenting on the recent appeal court ruling – 12-04-06 - in Swindon,
Andrew
Dillon, NICE Chief Executive said: “Today’s ruling is about how Swindon
PCT
made their decision. It doesn’t reduce the importance of having a
system
for licensing drugs, to make sure we know they are safe to use, or the
work
that NICE does, in helping the NHS to use new drugs in the right way.
Without
these things, we risk exposing patients to risks and the health service
to
using its money unwisely. “Herceptin still isn’t licensed and it won’t
be
until the summer. If and when it is, NICE stands ready to advise
patients
and those who care for them on the best way to use it. This will be
advice
for all the women who might potentially benefit from it and for all the
primary
care trusts who may need to make the funds available to enable its use.
It’s
only in this way that consistent decisions can be taken to bring an end
to
the uncertainty that faces both patients and the NHS.” NICE is
expecting
to issue guidance to the NHS on the use of Herceptin in July 2006,
subject
to the drug receiving a license. NICE is actively tracking the
licensing process
and will be in a position to go public on its recommendations quickly
once
the drug has been licensed for use in the UK. http://www.nice.org.uk
HEPATITIS C EPIDEMIC VASTLY UNDERESTIMATED BY GOVERNMENT
There are more than double the number of people infected with the
hepatitis
C virus (HCV) in England and Wales than the government has estimated,
delegates
at the British Society of Gastroenterology’s Annual Scientific Meeting
were
warned (Thursday 23rd March 2006). The government’s Health Protection
Agency
puts the figure at around 200,000. But William Rosenberg,
Professor
of Hepatology at the University of Southampton, claimed that the real
number
is around 466,000 although it could be as high as a million.
Assuming
the figure is around half million then 125,000 people will go on to
develop
serious liver disease which, by 2008, could be costing the NHS
£123
million in liver transplants. Antiviral treatment for hepatitis C is
much
more successful now than it was a decade ago and patients have at least
a
50:50 chance of clearing the infection. However, 86% of people
with
the virus are unaware they are infected, Prof Rosenberg warned.
“Unless urgent action is taken, about 116,000 people will die early
from
cirrhosis caused by hepatitis C that could have been treated,” he said.
“The
French diagnose five times as many patients as we do and they treat 12
times
as many,” said Professor Rosenberg. “Whereas we manage to treat
about
10% of those we diagnose and we don’t diagnose many.”
In France the rising tide of hepatitis C infection has been
successfully
reversed through anonymous HCV testing clinics and a huge public
awareness
campaign that has sought to destigmatise the disease, linked to
effective
treatment centres. Please click

PROPORTION OF BABIES BORN IN
EUROPE
AFTER IVF VARIES 20-FOLD
The BMJ 18-03-2006 reports that more than 2 per cent of babies born in
some
European countries are now the result of assisted reproductive
technology.
But there is an almost 20-fold variation in the proportion of babies
born
by such techniques overall. Denmark has the highest proportion, at 3.9
per
cent of all births in 2001, and Latvia has the lowest, at 0.2 percent
(International
Journal of Andrology 2006; 29:12-16). The average number of treatments
per
million inhabitants in 2001was 829, but this varied from 49 to 1923,
with
the United Kingdom the second lowest at 591.

DOCTORS
CALL
FOR BAN ON FORCE FEEDING AT GUANTANAMO
The LANCET – 11th March 2006 reports that 263 doctors from the UK, USA,
Ireland,
Germany, Australia, Italy and the Netherlands are calling for the US
government
to abandon force feeding and the use of restraint chairs in accordance
with
internationally agreed standards. The World Medical Association
specifically
prohibits force feeding in the Declarations of Tokyo and Malta, to
which
the American Medical Association is a signatory. Physicians attending
hunger
strikers have a responsibility to respect prisoners’ informed decision,
even
if they disagree. Those breaching the guidelines should be held to
account
by their professional bodies, state David Nicholl (City Hospital,
Birmingham,
UK) and colleagues in their correspondence letter. http://www.thelancet.com/journals/lancet/article/PIIS0140673606683268/fulltext
IMMOBILISATION NOT THE ONLY TRIGGER FOR DVT
The low pressure and low oxygen environment during air travel may
contribute
to the
development of deep vein thrombosis in some susceptible individuals,
suggests
a paper published in THE LANCET – 11th March 2006. Previous
studies
have found a 2–4-fold increased risk of thrombosis after air travel;
with
a greater risk after longer flights than after shorter ones. The
mechanism
of clot formation during air travel, however, is unclear. Scientists
think
immobilisation for long periods could play a part, but flight-specific
factors
may also contribute. Investigators in the Netherlands measured
the concentrations
of markers of clotting activation in blood samples from 71 healthy
volunteers
before, during, and immediately after an 8-hour flight. To disentangle
specific flight factors from immobilisation alone, they compared the
concentrations
in the same individuals at the same time points during 8 hours of
sitting
in a cinema and 8 hours of regular daily activities. 40% of the
participants
also had an increased risk of thrombosis, by being carriers of a
mutation
in the factor V gene or taking oral contraceptives. The authors found
increased
concentrations in markers during flight compared to the other two
situations,
especially in volunteers with other risk factors for thrombosis. http://www.thelancet.com/journals/lancet/article/PIIS0140673606683396/abstract
BOTTLE-FED BABIES AT RISK OF
ADULT
OBESITY
Bottle-fed babies are more likely to become obese children, a new UK
study
has claimed. It suggests that babies who are fed formula rather than
breast
milk and move onto solids early on consume more calories, thus
experiencing weight gain as a young child. The researchers also believe
that babies who
are breast-fed are better at regulating their own milk intake, stopping
when
they have had enough – but parents feeding babies from a bottle often
make
sure they finish it all and do not always reduce the quantity when the
child
moves onto solids. Scientists at the University of Bristol claim that
this increased milk intake, combined with weaning babies onto solids
too early,
means they are at risk of obesity as they grow older. The study
examined
the detailed feeding history of 900 mothers and their babies over a 14
year
period. It found that babies with a high calorie intake were 50 per
cent
more likely to be obese at the age of three, with a 25 per cent risk at
the
age of five. http://www.bris.ac.uk/news/2006/926.html
DEPRESSED CHILDREN MOST LIKELY
TO
TAKE ECSTASY
Childhood depression may raise the chances of a teenager using ecstasy,
according to new Research published in the online BMJ. It found
that
children with symptoms of anxiety and depression may have an increased
tendency
to use ecstasy in later years. Dutch researchers followed 1,580
individuals
from 1983, when they were assessed for mental health problems, to 1997
when
they were questioned about ecstasy use. They found that individuals
with
signs of anxiety and depression in 1983 showed an increased risk of
starting
to use ecstasy. Although use of ecstasy may initially enhance feelings
of wellbeing, they caution that over the long-term ecstasy may actually
increase
symptoms of depression. www.bmj.com
MRI OFFERS NEW HOPE FOR SEVERE EPILEPSY SUFFERERS
A new way of using magnetic resonance imaging (MRI) can detect minute
brain
lesions in sufferers of severe epilepsy, according to new Canadian
research.
Investigators found that automated techniques for improving the
detection
of brain lesions had been overlooked by conventional radiological
inspection.
The findings could make surgical treatment available to more severe
epilepsy
patients, in cases where seizures cannot be controlled by medication.
The
process works by identifying key features of focal cortical dysplasia
(FCD)
lesions on MRI scans, such as simultaneous grey matter (GM) thickening,
hyper-intense
signal, and blurring of the grey and white matter (GM–WM) transition.
In
all patients studied, the lesion causing epilepsy had at least two out
of
three of the characteristics identified and 78 per cent of the patients
had
all three traits present in FCD lesions. The Epilepsia Journal –

2006.
SHAM
ACUPUNTURE
BETTER THAN ORAL PLACEBO FOR ARM PAIN
An intriguing study published in the BMJ – 18TH February 2006 -
found
that treatment with sham acupuncture was more effective for arm pain
than
treatment with an oral placebo. The study involved 270 adult patients
with
arm pain due to repetitive use, who were randomised to treatment with a
validated
sham acupuncture device or a placebo tablet. Primary outcome was arm
pain
measured on a ten-point pain scale; secondary outcomes included symptom
severity, arm function, and grip strength. The study was created as an
offshoot of
the two-week placebo run-in period for a study comparing acupuncture
against
sham acupuncture and amitriptyline against placebo in arm pain, and at
the
end of this period patients were randomised to active treatments or to
continue
with the sham or placebo. Patients were aware that they might receive
placebo
throughout the study.

NEW BLOOD HEALTH DRINK LAUNCHED
A new type of health drink has just been launched which contains a
patented
natural extract from tomato, claimed to ‘smooth’ blood platelets and
help
maintain a healthy heart. It is approved by the Charity Heart UK.
to
help keep blood healthy. Director Michael Livingston says “The role
of
blood clots and blood health in cardiovascular health is less clear to
people
than the role of cholesterol. Cholesterol furs arteries and
causes
narrowing of the arteries BUT it is the thrombus or blood clot, caused
by
platelet aggregation (clumping together) that causes potentially fatal
heart attacks and strokes. Sirco is a scientific breakthrough in
the area
of heart health and it has been scientifically proven to help keep your
blood
healthy, benefit your circulation and so maintain a healthy heart and
cardiovascular
system. As part of a healthy diet and lifestyle, products such as
Sirco
and cholesterol reducing products can work together in helping to

SUDDEN INFANT DEATH SYNDROME – NEW WARNING
The number of sudden infant death syndrome (SIDS) cases that occur when
a parent sleeps with their infant on a sofa has increased in recent
years, according to a paper published online Wednesday January 18, 2006
by THE LANCET.
The authors strongly recommend that parents avoid this sleeping
environment.
The risk of SIDS is higher for male, pre-term, and low birthweight
infants,
and those sleeping on their side or front. Smoking during pregnancy and
exposure
to secondary smoke after birth can also increase the risk of SIDS. In
the 1991 UK campaign ‘Back to Sleep’, parents were told to put babies
on their back to sleep; death rates from SIDS subsequently fell.
In the latest
LANCET study, researchers at The Hospital for Children, Bristol looked
at
how the campaign has influenced factors that contribute to sudden
infant
death syndrome over the last 20 years and found that although the
number
of deaths in the parental bed has fallen, the number of co-sleeping
deaths
on a sofa has increased fourfold in recent years.
SUDDEN INFANT DEATH
SYNDROME
MAY BE RECURRENT
Women who have a baby that dies of sudden infant death syndrome (SIDS)
have
an increased risk of preterm delivery and complications in subsequent
pregnancies,
concludes an article in THE LANCET - 17th Dec 2005. As these
complications are risk factors for SIDS this could explain why some
women have recurrent
SIDS in their family, state the authors. Researchers at Cambridge
University
looked at data on maternity-hospital discharge and infant deaths for
over
258 000 women who had consecutive births in Scotland between 1995 and
2001.
They found that women whose previous infant died were two to three
times
more likely to deliver an infant who was small for their gestational
age,
and two to three times more likely to have a preterm delivery. Women
who
had babies which were small for their age or delivered preterm had a
two-fold
increased risk of SIDS occurring in their subsequent births. The
investigators found that the association persisted even after they took
into account other
possible risk factors for SIDS, such as smoking status, maternal age,
and
marital status. http://www.thelancet.com/journals/lancet/article/PIIS0140673605678889/abstract
DUMMIES EFFECTIVE IN PREVENTING SID?
New research from the USA indicates that the use of a dummy seems to
reduce
the risk of sudden infant death syndrome (SID) and possibly reduces the
influence
of known risk factors during sleep. The participants were mothers
or
carers of 185 infants whose deaths were attributed to SIDS and 312
randomly
selected controls matched for ethnicity and age. Use of a dummy
was
associated with a reduction in risk in every category of
sociodemographic
characteristics and risk factors examined. The reduced risk
associated
with use seemed to be greater with adverse sleep conditions such as
sleeping
prone or on one side and sleeping with a mother who smoked. Please

PROVISION OF
CHILDHOOD VACCINATIONS
A survey conducted by PULSE magazine, based on the first 200 responses,

MELATONIN REDUCES CANCER RISK
A new Canadian study highlights a link between melatonin levels and
cancer
progression, suggesting the protein could have an influence over the
spread
of the disease. Through analysis of previous studies researchers found
large
doses of melatonin reduced the risk of death at one year by 34 per
cent.
Melatonin helps regulate sleeping patterns and its natural production
in
the body is stimulated by darkness. The research was instigated
after
earlier studies showed a link between shift work and cancer rates.
Such
workers melatonin production is disrupted when they sleep during the
day. The findings are published in the JOURNAL
OF PINEAL RESEARCH.
TRAFFIC NOISE LINKED TO HEART ATTACKS
A German study has shown that there is a discernible link between
chronic
noise exposure and an increased risk of heart attack. Published
in
the EUROPEAN HEART JOURNAL, the research suggests that the risk
associated
with noise appears to be linked more with the physiological effects
than
the annoyance it causes, though results varied between men and
women.
The team have called for the noise level requiring workplace ear
protection
to be lowered from the current 85 decibels in Europe to between 65 and
75
decibels, particularly for those with existing cardiovascular
disease.
The study involved 32 hospitals between 1998 and 2001 and more than
4,000
patients, half of them admitted with heart attacks. The Naromi (Noise
and
Risk of Myocardial Infarction) research discovered that general
environmental
noise, such as that of traffic, increased the risk of heart attack by
nearly
50 per cent for men and by about three-fold for women. A similar
US
study found that working in noisy environments could elevate blood
pressure
and heart rate. Click

BREASTFEEDING COULD PROTECT AGAINST GLUTEN INTOLERANCE
Breastfeeding could help mothers protect their babies against gluten
intolerance,
according to a new study. Research by a team at the Manchester
Children's
University Hospital and published in the journal ‘Archives of Diseases
in
Childhood,‘ 14th November 2005, found that the longer children
are
breast fed the less likely they are to develop celiac disease, the
intolerance
to proteins found in wheat, rye and barley. It was also found by
breastfeeding
during the introduction of solid foods, as well as increasing the time
a
baby is breastfed for, the chances of developing gluten intolerance
were
reduced by 52 per cent.

SLEEPING
PILLS MAY DO MORE HARM THAN GOOD IN ELDERLY
A meta-analysis conducted by Canadian researchers suggests that the
risk
of using sedatives may outweigh the benefits in elderly patients,
particularly
if they have additional risk factors for cognitive or psychomotor
adverse
events. The investigators selected RCTs of any pharmacological
treatment
for insomnia taken for at least five consecutive nights in people aged
60
or over, who were otherwise free of psychiatric or psychological
disorders.
The research concluded that the magnitude of improvements in sleep with
sedative
use are statistically significant, but small, whilst the increased risk
of adverse events is statistically significant and potentially
clinically relevant
in older people at risk of falls and cognitive impairment. http://bmj.bmjjournals.com/cgi/rapidpdf/bmj.38623.768588.47v1
FIRST BIRD ‘FLU VACCINE
The Health Protection Agency (HPA) reports that European Union
scientists
and researchers from Sanofi-Pasteur have developed the first human
vaccine
for the H7N1 bird flu virus. This new vaccine (‘RD-3’) is the first
vaccine
to be developed using a new technique called ‘reverse genetics’ and
will
enter into clinical trials in spring 2006. The project began in
September
2001 by taking the H7N1 virus that caused outbreaks in Italian poultry
in
1999 and was related to the H7N7 poultry virus in the
Netherlands.
The HPA stress that the risk of H7 emerging as a pandemic influenza
strain
is considered quite low, but it is hoped that this research will be a
valuable
resource for pandemic vaccine development in the future. http://www.hpa.org.uk/hpa/news/articles/press_releases/2005/051104_flu.htm

YOUNG DIABETIC PATIENTS WINS
TRIATHLON
& SPONSORSHIP
Twenty-one year old Gary Blakie, who developed Type 1 diabetes at the
age
of 12, has won the 2005 Triathlon World Championships in Honolulu,
Hawaii.
He completed the gruelling 1.5km swim, 40km bike ride and 10km run in
an
impressive 2 hrs and 18 minutes. Commenting on his success he
said
“I’m not an athlete who became a diabetic – I was a kid who developed
diabetes
who became an athlete. My greatest motivation to overcome my diabetes
has
been to compete in events like this and prove to the world I can
succeed
and be the best I can be – it makes all the blood, sweat and tears
worth
while.” Because Gary is such a positive role model for other teenagers
and
young adults with diabetes, sanofi-aventis has agreed to provide
sponsorship
for his sporting activities.
The medication that keeps Gary sporting fit is a combination of
long-acting
basal insulin analogue to control his background insulin levels and
short-acting
insulin taken at mealtimes. Gary’s diabetes had previously been
treated
with a variety of insulins, but his blood sugar levels were very
erratic
until he was put on his new regimen.
Commenting on his treatment, Gary said, “With my old insulin I couldn’t
get my best performance – if my blood sugar was too low my legs felt
like
jelly; too high and I felt sick. With the new regimen there are no peak
periods,
so the insulin supply is constant throughout the event and my
performance
isn’t impaired. I can push myself to the extremes. I eat better, sleep
better,
work better and feel better.” Please click here to email for further

'DOUBLE
DEATH
RATE' FOR EARLY RETIRERS
People who stop working early are twice as likely to die as people who
work
for longer, according to new research published in the BMJ. The
US
study found that mortality rates were almost twice as high in the first
ten
years of retirement after 55, compared to those who continued working
until
65. It seems that the long term survival of people who retire
early
at ages 55 or 60 is no better than that of those who retire at
55.
In the study, mortality improved with increasing age at retirement for
people

MMR NOT LINKED TO AUTISIM
A large systematic review has found no reliable evidence that the MMR
vaccine
can trigger long-term harms such as autism or Crohn's disease. It is,
however, effective in reducing the rate of the three diseases
covered. The reviewers
carried out a comprehensive literature search for high-quality studies
on
the use of the vaccine, and located 31 (of 139) that were sufficiently
robust
and unbiased. Analysis of these studies found no credible evidence to
link
the MMR vaccine and any long-term disability, including Crohn's disease
and
autism. The authors also conclude that mass use of the vaccine is
successful
in preventing measles, mumps and rubella in the countries where it has
been
used, and that the lack of confidence in the vaccine prompted by
unreliable evidence has caused great damage to public health. The

CHARITY
SLAMS SEXUAL HEALTH PRIVACY BREACH
Allowing social workers and police access to the confidential sexual
health
files of teenagers may make them reluctant to seek sex advice, says the
health
charity Brook. It has launched a campaign (October 19th 2005) in
response
to reports that the government is considering giving police and social
workers
access to teen sexual health files in an attempt to improve child
protection measures. Brook believes that breaching the
confidentiality of files
could have the opposite effect to the one desired, as young people will
become
afraid of being 'found out' if their files lose their confidential
nature.

RA DRUG PROVES EFFECTIVE AGAINST PSORIASIS
A rheumatoid arthritis drug can successfully treat moderate to severe
cases
of psoriasis, according to the results of a randomised trial published
in
THE LANCET – 15th October 2005. Manchester researchers recruited 378
patients
with moderate to severe psoriasis to intravenously receive infliximab
or
placebo at 0, 2, and 6 weeks, then every 8 weeks until week 46. The
researchers
assessed signs of psoriasis using the psoriasis area and severity index
(PASI)
and nail psoriasis severity index (NAPSI). They found that at week 10,
80%
of patients treated with infliximab achieved at least a 75% improvement
from
their baseline PASI, and 57% achieved at least a 90% improvement,
compared
with 1% and 3% in the placebo group. The investigators also found that
the
positive effect of the drug was sustained through to week 24 and up to
week
50 for most patients. A quarter of the patients taking the drug had
complete
clearing of skin psoriasis (PASI of 0) compared with none in the
placebo
group. Patients receiving infliximab also experienced a good
response
in nail psoriasis, which is present in 20–50% of psoriasis patients and
is
often thought of as sign of treatment-resistant disease. By week 24 of
the
trial, those receiving the drug were experiencing a 56% average
decrease
in this condition, and this response was maintained throughout the
trial. http://www.thelancet.com/journals/lancet/article/PIIS0140673605675666/fulltext
PRE-ECLAMPSIA
RECURS ACROSS GENERATIONS
According to a paper in the BMJ - 15th October 2005 - increased risk
for
pre-eclampsia is genetically transmitted from both mother and father.
Studying
a population based cohort, researchers examined almost 500 000
mother-offspring
units and almost 300 000 father-offspring units from the Norwegian
medical
birth registry. Women born from pre-eclamptic pregnancies were more
than
twice as likely to develop pre-eclampsia themselves than other women,
while
the corresponding increased risk in pregnancies fathered by a man who
was
born from a pre-eclamptic http://bmj.bmjjournals.com/cgi/content/full/bmj;331/7521/877
BCG VACCINE EFFECT AGAINST
TUBERCULOSIS
INFECTION AND DISEASE
BCG vaccination can protect children from tuberculosis (TB) infection
as
well as active TB disease, according to a study published online in THE
LANCET
-Thursday October 13th 2005. There are about 10 million
cases
of TB globally each year and 1 in 3 people are infected with the TB
bacterium.
According to the report, BCG is the most widely used vaccine worldwide,
but
its mechanism of protection is poorly understood. It is thought to
prevent progression of infection to active TB, but whether it protects
against the
acquisition of infection itself has not been investigated in humans.
The
effect of BCG vaccine has been difficult to ascertain because, until
recently,
the century-old tuberculin skin-prick test (TST) was the only method
for
detecting infection. However, TST cannot reliably distinguish
between
TB infection and BCG vaccination. In the study reported in THE LANCET
researchers
used the more accurate T-cell based blood test called the ELISpot and
TST
to assess infection. UK researchers investigated risk factors for
TB infection in 979 children from Turkey. All children taking part
shared a
household with at least one adult with TB. 770 of the children had a
BCG
scar. The researchers found that the absence of a BCG scar was a
strong,
independent risk factor for infection in TB-exposed children, while the
presence
of a BCG scar was associated with a 24% reduction in risk of being
infected. The authors state that this finding furthers our
understanding of the biology
of TB transmission and has important implications for the development
of
new TB vaccines. “Contrary to prevailing theory that BCG
vaccination
protects only against tuberculosis disease, the results suggest that
the
vaccine also protects against tuberculosis infection. Children
can
be protected against TB infection by vaccination and this opens a new
door
for the development of new, improved vaccines.” http://www.thelancet.com.
EARLY STAGE BREAST CANCER
PATIENTS
TO GET HERCEPTIN
According to the Department of Health, henceforth all women diagnosed
with
early stage breast cancer will be tested for suitability for treatment
with
Herceptin (trastuzumab). Apparently, of the 35,000 women diagnosed with
breast
cancer each year, about 20,000 will be suitable for HER2 testing.

SCIENTISTS MAKE IMMUNITY BREAKTHROUGH
A method of dramatically boosting the human immune system, which could
lead
to improved cancer treatments, has been discovered by researchers in
the
US. While researching the immune system responses of healthcare
workers
accidentally exposed to HIV and had then received antiretroviral
therapy
(ART) they discovered that ART dramatically increases the production of
cells
from which the immune system makes disease-attacking T cells.
Furthermore,
none of the healthcare workers involved developed HIV infections.
One
of the potential uses envisaged is to use the ART treatment as a way to
use
tumour components to immunize cancer patients against their own cancer
cells. However, the real challenge in immunotherapy is to
generate T cells able
to identify cancer cells and kill them and not be deceived into
ignoring
them as acceptable versions of normal cells.
EXERCISE IN MIDLIFE COULD REDUCE THE RISK OF DEMENTIA
Being physically active in midlife could decrease a person’s risk of
dementia
and Alzheimer’s disease (AD) later in life, concludes an article
published
online - Tuesday October 4 2005) by THE LANCET NEUROLOGY. Swedish
researchers
randomly selected 1449 people aged 65–79 who had been surveyed about
their
leisure-time physical activity in 1972, 1977, 1982, and 1987 to take
part
in the study. The investigators re-examined the participants in 1998
and
found that individuals participating in leisure-time physical activity
at
least twice a week had a 60% lower odds of AD compared to sedentary
people
(individuals participating in physical activity less than twice a
week).
The active group had 50% lower odds of dementia compared to the
sedentary
group. The researchers also found that in individuals who are
genetically
susceptible to AD (carriers of the gene variant APOE _4), physical
activity
had more pronounced effects against developing dementia or AD in later
life.

STUTTERING CAN BE TREATED BY EARLY INTERVENTION
Early intervention in the preschool years is effective in treating
stuttering,
according to a paper published in the BMJ – 24th September 2005.
In
a pragmatic, open plan, randomised trial of 54 children, Australian
researchers
found that children who were treated on an early treatment programme,
had
significantly fewer stuttered syllables after nine months than children
in
the control group. The paper states that although some children
who
stutter in their preschool years improve without treatment, identifying
them
in advance is impossible. Treatment should begin in the preschool years
because
it is more effective then. http://bmj.bmjjournals.com/cgi/content/full/bmj;331/7518/659
RESISTANCE TO ANTI-FLU AGENTS INCREASING WORLDWIDE
Worldwide resistance to drugs used to treat influenza has increased by
12%
since the mid nineties, concludes a report published online (Thursday
September
21, 2005) by THE LANCET. Adamantanes have been used to treat influenza
A
virus infections for more than 30 years. However, in the largest
study
of adamantane resistance to date, US researchers screened 7000
influenza
A isolates for gene mutations known to confer drug resistance. They
found
that drug resistance increased from 0•4% in 1994–1995 to 12.3% in
2003-2004.
They also found that 61% of resistant viruses isolated since 2003 were
from
people in Asia. Some Asian countries had drug resistance frequencies
exceeding
70%. This is thought to have broad implications
for agencies
and governments planning to stockpile these drugs for epidemic and
pandemic
strains of influenza. Researchers suggest that with the
increasing rates
of resistance shown in the new research, amantadine and rimantadine
will
probably no longer be effective for treatment or prophylaxis in the
event
of a pandemic outbreak of influenza. http://www.thelancet.com
FLU VACCINES HAVE MODEST EFFECTIVENESS IN ELDERLY PEOPLE
Vaccines against influenza are modestly effective for elderly people in
long-term care,
but for those in the community their effectiveness is even less,
according
to an Italian study published online in THE LANCET - September 21,
2005.
The research concludes that a more comprehensive and perhaps more
effective
strategy in controlling acute respiratory infections, relying on
several
preventive interventions that take into account the multi-agent nature
of
infectious respiratory disease and its context (such as personal
hygiene,
provision of electricity and adequate food, water and
sanitation). http://www.thelancet.com
WOMEN URGED TO TAKE VITAMIN D
A new campaign urging women to take more vitamin D to prevent
osteoporosis
has been launched (September 2005) after research revealing that 97 per
cent
of hip fractures occur because of brittle bones. The campaign,
launched
by the charity Women's Health Concern (WHC), encourages women to take
Vitamin
D supplements, claiming that otherwise they would have to eat nine eggs
or
drink thirty litres of milk to get the recommended daily amount.
The
campaign coincides with the launch of a new once-a-month brittle bone
treatment
called Bonviva, devised to tackle post-menopausal osteoporosis. Click here to email for more

MENTAL HEALTH COMPULSION WARNING
The Government has hugely underestimated the number of people who would
undergo
compulsory community-treatment should the new mental health bill become
law,
according to a newly published King's Fund study. Over the next
10
to 15 years the number of people with mental health problems placed
under
community-treatment orders may reach several thousands. The
report
claims that the Department of Health estimated this figure to start off
at
just 1,400, since it did not take into account the year-on-year
increases
that are likely to occur. According to the mental health charity,
Mind,
numbers are predicted to be 13,000 or more – ten times the Government
estimate.
This could mean, according to the charity, that far too many people
will
be swept up into compulsory treatment in the community. Please click here to email for further

COPD
DEATHS
POISED TO OVERTAKE BREAST CANCER
Announcing the results of an NOP survey commissioned to launch The
British
Lung Foundation’s new COPD campaign (September 13th 2005), the
BLF
warns that chronic obstructive pulmonary disease is about to overtake
breast
cancer as the UK’s fourth biggest killer of women. Of the 1000
women
surveyed, only one per cent ranked COPD as their main health
worry.
This percentage was only slightly higher among women who smoked despite
the
fact that they are at 13 times greater risk of the condition. The
majority
of women, the survey revealed, do not even realise that COPD is life
threatening
and are far more concerned about diseases such as ovarian and cervical
cancer,
even though they kill just a fraction of the number who die from
COPD.
It is now the only major cause of death in women that is rising
sharply. http://www.lunguk.org
CHRONIC
STRESS
PROTECTS FROM BREAST CANCER
Exposure to chronic stress protects women from breast cancer, probably
by
impairing endogenous synthesis of oestrogen. A prospective cohort study
published
in the BMJ – 10th September 2005 - involving 6689 women, showed that
women
with high levels of stress had a 40% lower risk of getting first time
primary
breast cancer. Moreover, the researchers found a dose-response
relation,
and the protective effect of stress was more pronounced in women
receiving
hormone therapy. Still, the cumulative consequences of stress on health
may
be disadvantageous, authors warn. http://bmj.bmjjournals.com/cgi/content/full/bmj;331/7516/548
VOCABULARY TEST TO SPOT EARLY ALZHEIMER’S DISEASE
A simple vocabulary test could improve early diagnosis of Alzheimer's
disease;
a new British study has shown. It seems that people
routinely
forget seldom-used words when they enter the initial stages of the
disease.
Researchers asked 96 Alzheimer's patients and 40 similarly aged healthy
volunteers
to list as many animals as possible in one minute. They were then asked
to
list types of fruit in the second minute. Evidence of a shrinking
vocabulary
in Alzheimer's patients was clear. They could only list between ten and
15
types of animal or fruit on average, while the healthy controls reached
20
to 25. The results were given at the British Association’s recent
Festival
of Science in Dublin.
CHICKENPOX

THIRD
OF
PATIENTS CANNOT BOOK WITH GP
A new report by the Healthcare Commission has found that 30 per cent of
GP
patients could not arrange an appointment more than three days in
advance.
Their research has also revealed that 12 per cent of patients were
unable
to see a GP within two working days, although the vast majority said
they
were happy with the care they received. In response,
Government
has announced new measures guaranteeing patients the choice of booking
an
advance appointment, saying that not allowing them to do so was
"unacceptable".
DOH URGE HEALTH PROFESSIONALS TO HAVE ‘FLU JAB
October 3rd 2005 is launch date for the Department of Health’s ‘flu
campaign.
This year they will be targeting health professionals directly involved
in
patient care, as well as vulnerable members of the public. The
need
to encourage the profession in this way has been highlighted by new
research
indicating that only 16% of health professionals were vaccinated last
year.
All medical professionals as well as people who have serious
respiratory,
heart, liver or renal disease, diabetes or anyone who has lowered
immunity
as a result of disease or treatment and all those aged over 65 are all
entitled
to a free jab. Please click

HYPERTENSION CAN BE MONITORED BY PATIENTS
The BMJ – 3rd September 2005 – reports on a trial of patients with
hypertension
which indicates that self blood pressure monitoring is
effective.
Over 400 people were randomised in eight general practices in south
Birmingham
to the self monitoring intervention or usual practice. After one year,
no
differences in systolic or diastolic blood pressure, anxiety, health
behaviours,
or number of prescribed drugs were found between the groups, and
patients
who self monitored lost more weight, rated self monitoring better than
being
monitored by a doctor or a nurse, and consulted less often. http://bmj.bmjjournals.com/cgi/content/full/bmj;331/7515/493
CHRONIC PAIN IS POORLY MANAGED
A fifth of adults in Europe have moderate to severe chronic pain, and
in
many cases their symptoms are inadequately managed, says a recent study
in
the European Journal of Pain, published online and reported in the BMJ
–
3rd September 2005. The authors say that the problem needs
to
be taken more seriously by health care providers and those responsible
for
health care policies and allocations of resources. http://bmj.bmjjournals.com/cgi/content/full/331/7515/476-a?etoc
CLINICAL
EFFECTS OF HOMOEOPATHY ARE PLACEBO EFFECTS
The evidence for a specific effect of homoeopathic remedies is weak,
according
to an article THE LANCET – 27th August 2005. The authors conclude
that
the clinical effects of homoeopathy are compatible with placebo
effects
Researchers in Switzerland compared 110 placebo controlled, randomised
trials
of homoeopathy with 110 conventional-medicine trials matched for
disorder
and type of outcome. When the analysis was restricted to large
trials
of high quality there was no convincing evidence that homoeopathy was
superior to placebo, whereas for conventional medicine an important
effect remained.
A LANCET editorial comments ‘Now doctors need to be bold and honest
with
their patients about homeopathy’s lack of benefit, and with themselves
about
the failings of modern medicine to address patients’ needs for
personalised
care. http://www.thelancet.com
MENTAL HEALTH OF UK HOSPITAL CONSULTANTS IN DECLINE
The prevalence of poor mental health and burnout among hospital
consultants
in the UK
increased in the period 1994 to 2002, according to a Research Letter in
THE LANCET (27TH August 2005). In 1994, the Cancer Research UK
London
Psychosocial Group surveyed over 800 UK hospital consultants and found
a
27% prevalence of poor mental health. The respondents were from five
specialties:
gastroenterology, radiology, surgical oncology, clinical oncology, and
medical
oncology. In 2002, the researchers re-assessed the situation and found
that
the proportion of consultants with psychiatric illness increased to 32%
in
2002. The prevalence of burnout also increased from 32% in 1994 to 41%
in
2002.
The survey revealed that an increase in job stress, unmatched by a
comparable
increase in job satisfaction accounted for the deterioration in mental
health
over this time period. The researchers found that clinical oncologists
had
the greatest increase in the prevalence of poor mental health and
burnout
compared with the other specialties. The authors state that approaches
designed
to reduce consultants’ workload and enhance their job satisfaction are
urgently needed.
The author of the report, in an unpublished comment, concludes “There
seems
to be several underlying reasons for this worrying development. It
appears
in part due to increased stress from being poorly resourced and having
responsibility
for the quality of the work of other staff, together with trying to
meet
the expectations of relatives. On top of this, these consultants have
an
enormous workload coupled with insufficient levels of satisfaction from
some
areas of their work.
“The changes that have occurred in the NHS over the 8-year period
aim
to benefit patients, but appear to have a negative effect on the
working
lives of consultants.”
An accompanying comment suggests that if the direction and ethos of
restructuring
of the NHS continue unaltered, consultants will have to adopt to leave
the
NHS or to compromise their professionalism.” http://www.thelancet.com
IMPROVING SERVICES FOR CHILDREN WITH CANCER
The National Institute for Health and Clinical Excellence (NICE) and
the
National Collaborating Centre for Cancer (NCCC) have today launched
guidance
which aims to standardise services for children and young people with
cancer
in England and Wales. Each year in the UK there are approximately 1500
new
cases of cancer diagnosed in children under the age of 15, according to
the
United Kingdom Children’s Cancer Study Group (UKCCSG). Overall survival
rates
for children are now approximately 70%. This guidance, the seventh in
the
Improving Outcomes in Cancer Series, provides recommendations for
children
from birth and young people in their late teens and early twenties
presenting
with malignant disease, and the whole range of NHS services required to
meet
their needs. Key recommendations include:
- All
care
for children and young people under 19 years old must be provided in
age-appropriate
facilities.
- All
children
and young people must have access to tumour specific or
treatment-specific
clinical expertise as required.
- All
aspects
of care for children and young people with cancer should be undertaken
by
appropriately trained staff.
ARTHRITIS
REPORT REVEALS POOR PATIENT SUPPORT IN PRIMARY CARE
Arthritis Care has published a new report – August 18th 2005 -
highlighting
the plight of patients concerned about the safety of arthritis drugs.
It
reveals that fewer than four in ten people with osteoarthritis (OA) are
happy
with their current medication.
The charity is calling on GPs to complete reviews for all OA patients
within
six months rather than working to current government guidance which
means
that many have to wait over a year for a review of their arthritis and
medications.
The report also reveals how the pain of OA impacts people’s everyday
lives.
Almost half of those surveyed and currently receiving pain relieving
medication
are in pain most or all of the time. Their pain impacts on a range of
activities
from household tasks to social activities. 80 per cent of the people
surveyed
said they wake up at least once during the night because of pain.
Because deciding on the right medication isn’t a black or white
decision,
Arthritis Care believes that involving patients in the decision making
with
regular consultations and reviews of treatment should be standard good
practice.
This view is endorsed by ABD Member, Dr Mike Smith, a GP who has
written
extensively on arthritis: Commenting on the report, he said:
“People with long-term conditions such as OA should be able to sit down
regularly with their GP and talk about how their condition is affecting
their
lives, as well as the risks and benefits of any medications they are
taking.”
Furthermore, he went on to emphasise that when there is a public debate
about
the safety of particular medicines, patients should be invited in for
consultation and not just left to wait for the next annual
review. Living with
Arthritis – a spotlight on the continuing impact of chronic
osteoarthritis
pain, was published 18th August 2005. To email for more

exacerbations.
It is hoped that by bringing together the key steps for primary care,
patients
will have their conditioned managed more proactively. Please click here to email for more

COGNITIVE BEHAVIOUR THERAPY FOR IRRITABLE BOWEL SYNDROME
The BMJ – 20th August 2005 – has the results of a randomised controlled
trial which found that in patients with irritable bowel syndrome (IBS),
cognitive
behaviour therapy (CBT) provided by primary care nurses gave more
benefit
than mebeverine only for up to 6 months. However, the effect was
reduced
after one year. The trial was conducted in 10 general practices in
London
and involved 149 patients with moderate or severe IBS resistant to
mebeverine. http://bmj.bmjjournals.com/cgi/content/full/bmj;331/7514/435
BUG BUSTING KIT OF COMBS INCREASES ERADICATION OF HEAD
LICE
The Bug Buster kit of fine tooth combs, used over two weeks, more
effectively
eradicates head lice than a single treatment of pediculicides malathion
and
permethrin bought over the counter. The BMJ – 13th August 2005
reports
on a single blind randomised controlled trial of 133 people aged 2-15,
recruited
through general practices, pharmacies, and primary schools.
Eradication
rates at two to four days after the end of treatment were assessed. .
Of
those who used the Bug Buster kit 57% had no lice or eggs compared with
13%
using pediculicides (relative risk 4.4%, 95% confidence interval 2.3 to
8.5%).
The Bug Buster regimen comprises four sequential combings on wet,
conditioned
hair, three days apart. http://bmj.bmjjournals.com/cgi/content/full/bmj;331/7513/384
LIQUID DETERGENT TABLETS POSE EYE INJURY RISK TO CHILDREN
Liquid tablet forms of washing detergent pose a new household risk to
children,
state the authors of a letter in THE LANCET 13h August 2005. A
Dublin
hospital treated six children, over a 6-month period, with alkali eye
injury
caused by a liquid detergent tablet. The children, aged 18 months
to
3 years, had squeezed a tablet causing it to burst and spray detergent
over
their eyes. The children presented with damage to the cells lining the
cornea,
and four had significant injury to the conjunctiva. All patients were
admitted
to hospital and stayed for 2 to 5 days. The damaged eye cells
eventually
healed. The authors note that more serious damage may have resulted if
the
children had not had prompt irrigation of their eyes after the chemical
splash.
The letter states that “Alkali eye injuries are potentially the most
severe
form of chemical eye injury. Although the detergent packaging
displays
a warning that the contents are irritant, and that the products should
be
kept out of reach of children, the real risk of injury posed may not be
appreciated
by consumers. We propose that the warning label should be more obvious,
and
that the packaging should be modified to make it child proof.”

SUPPLEMENTS DON'T PROTECT THE ELDERLY FROM INFECTIONS
According to a trial published in the BMJ – 6th August 2005 -
multivitamin
and multimineral food supplements don't seem to protect elderly people
from
infections or improve their quality of life. The double blind
controlled
trial randomised 910 people aged over 64 to supplementation or placebo.
They
found no significant differences in frequency of attending primary care
for
infection, antibiotic prescriptions, hospital admissions, adverse
events,
compliance, self reported days of infection, and quality of life. http://bmj.bmjjournals.com/cgi/content/full/bmj;331/7512/324
BREAST CANCER SCREENING DOES NOT SAVE LIVES?
Reported in the BMJ – 6th August 2005 - a US study indicates that
breast
cancer screening in "real world" situations is not effective in
preventing
mortality. The study, one of the largest completed to date
looking
at the effectiveness of breast cancer screening, was published in THE
JOURNAL
OF THE NATIONAL CANCER INSTITUTE (2005;97: 1035-43)[ It
looked
at the history of screening in the three years before their diagnosis
of
cancer in 1351 women who died of breast cancer between 1983 and 1998.
They
compared these screening rates with those in a control group of 2501
cancer-free
women, matched for age (40-49 years or 50-65 years) and risk of
developing
cancer (average risk or greater risk because of family history or a
breast biopsy.) The women were enrolled in six well regarded
health plans
throughout the US. The screening was by clinical examination
alone,
mammography alone, or clinical examination and mammography. Mortality
did
not differ according to type of screening. However, although the
study
showed no advantages for breast screen programmes, the researchers
still
recommended screening. An accompanying editorial comments that
breast
cancer screening in the community may be less effective than in
controlled trial situations because of problems implementing
programmes. Click

NATIONAL BOWEL CANCER SCREENING
Government announced plans – 3rd August 2005 - for a national bowel
cancer
screening programme, to be phased in from April 2006. Men and women
aged
60-69 years old will be screened every two years. The programme will
cost
£37.5 million in its first two years of roll-out. Home
testing
kits will be sent to around two million people in the target group each
year
to enable them to do the test in the privacy of their own homes. Click

HORMONE THERAPIES BRANDED AS CARCINOGENIC
According to a report in PHARMATIMES, the World Health Organisation's
International
Agency for Research on Cancer (IARC) has branded combination oestrogen
with
progestogen products as "carcinogenic to humans." However it consider
there
to be both beneficial and adverse effects which should be discussed on
an
individual basis. The IARC says ‘there is a small increase in the
risk
of breast cancer amongst users of oral contraceptives, while the risk
of
cervical cancer increases with duration of use, and liver cancer is
also
more prevalent in long-term users. However, OCs decrease the chances of
developing both endometrial and ovarian tumours’. For menopausal
therapy it adds,
‘the risk of breast and endometrial tumours are raised and increase
with
duration of use, and there was no evidence to suggest HRT is protective
at
any site’.

ANTI-SOCIAL BEHAVIOUR SMOKING RISK
Mothers who smoke during pregnancy face an increased risk of
anti-social
behaviour in their children according to new research from the
Institute
of Psychiatry. A small but significant independent link between
smoking
during pregnancy and antisocial behaviour has been found. The
study,
published in the British Journal of Psychiatry, also found a link with
attention

HEALTH COMMITTEE WARNS
OF
POTENTIAL DANGERS OF SOYA
The BMJ 30th - July 2005 - reports that the Israeli health ministry has
recommended
that the consumption of soya products be limited in young children and
avoided,
if possible, in infants. They also advise that adults should eat
soya
only in moderation, pending future studies. Because the research
showing
problems from soya, which include a higher risk of cancer and
male
infertility, is based on animal or retrospective human studies, the
recommendations
are precautionary. Soya consumption is high in Israel, and use of soya
based
baby formula is among the world’s highest per capita due to a number of
reasons, most prominently kosher food practices. http://bmj.bmjjournals.com/cgi/content/full/331/7511/254-a?etoc
BETA-BLOCKERS INEFFECTIVE ON HEART PATIENTS?
According to a report in the NEW ENGLAND JOURNAL OF MEDICINE – July 28
2005
- new research casts doubt on the practice of giving heart patients
beta-blockers
before and after major surgery. It suggests that the drugs may
even
be harmful to low risk heart patients who, were significantly more
likely
to die. However, the research supports the continued use of
beta-blockers
for high-risk patients having surgery. The US research analysed
medical
records of about 664,000 patients with a history of heart-related
problems
and who were having non-cardiac surgery in 2000 and 2001. They found
that
in a sample of that group, low-risk patients who received beta-blockers
had a 43 per cent increased risk of death. Specialists say two ongoing
trials
should help further determine whether beta-blockers pose any risk to
low-risk
patients. http://content.nejm.org/cgi/content/abstract/353/4/349?
ECHINACEA INEFFECTIVE FOR PREVENTING COLDS
Another report in THE AMERICAN JOURNAL OF MEDICINE - 21ST July
2005
- suggests that echinacea is ineffective for preventing or
treating
the common cold. In this study, researchers evaluated the effect
of
chemically defined extracts from Echinacea angustifolia roots on
rhinovirus
infection. Three preparations of echinacea, with distinct phytochemical
profiles,
were produced by extraction from E. angustifolia roots. They were
tested
on 437 volunteers randomised to either prophylaxis (starting 7 days
before
the virus challenge) or treatment (beginning at the time of challenge)
with
one of these preparations or with placebo. Data for 399
volunteers
challenged with rhinovirus type 39 and observed for five days showed no
statistically
significant effects of the three echinacea extracts on rates of
infection
or severity of symptoms. Furthermore, there were no significant effects
of
treatment on the volume of nasal secretions, on polymorphonuclear
leukocyte
or interleukin-8 concentrations in nasal-lavage specimens, or on
quantitative-virus
titre.

A
PATIENT-LED
NHS WILL NOT IMPROVE HEALTH
Government’s plans for improving the NHS by making it patient-led
and
encouraging patients to complain more will not lead to better health,
states
an editorial in THE LANCET - 30TH July 2005. Treating patients’
feedback
in the same way as supermarkets treat customer complaints fails to
address
the far more difficult issue of strengthening the patient-doctor
partnership.
The editorial comments:
“Patients have a wealth of information at their fingertips through the
internet.
What most do not have, however, is the skill and knowledge to sift
useful
and valid information and evidence from useless or harmful advice. In a
mutually
beneficial and effective patient-doctor partnership, medical expertise
and
knowledge need to be an accepted and valued part of that interaction,
just
as much as doctors need to have the time and skills to communicate
preventive
measures and treatment choices to patients appropriately. Patients do
not
need to complain more. Instead, doctors and patients need to listen to
one
another more. Naked consumerism will not lead to better health.” www.thelancet.com
PROF MEADOW VERDICT COULD PUT CHILDREN AT GREATER RISK OF ABUSE
The verdict of serious professional misconduct given by the GMC against
Professor
Roy Meadow last week was not only unjust but will also profoundly
damage
the future of child protection services in Britain, states a comment in
THE
LANCET - 23rd July 2005. Richard Horton, Editor, writes that the real
danger
of the judgment against Prof Meadow is that, by worsening the
professional
conditions in which child protection services are provided, children
will
be put at greater risk of abuse and murder. He argues that the GMC's
decision
removes any incentive for the reform of judicial procedures that fail
to
deal properly with expert evidence. He states that trainee
paediatricians are now less likely to seek a career in child
protection, while those in
the field may weaken their conclusions about alleged child abuse in
court
to avoid the aggressive and improper intrusion of the GMC into their
work.
Horton also accuses the GMC of making an unfair example of Prof Meadow
in
the wake of the Harold Shipman case in order to protect its own status.
He
writes: "Many doctors today believe that the GMC is acting more out of
self
interest than public interest. It is impossible to put into words the
low
esteem with which the GMC is currently held by many among the rank and
file
of medicine in the UK today. This is not only bad for doctors; it is
also
bad for patients." Dr Horton adds: "The real danger of the judgment
against
Meadow is that, by worsening the professional conditions in which child
protection
services are provided, children will be put at greater risk of abuse
and
murder." The lamentable judgment against Prof Meadow is further
evidence
that this is so. He now has 28 days to appeal the GMC's verdict. On
behalf
of children and his colleagues working in paediatrics and child
protection
everywhere, he should certainly feel encouraged and supported in
challenging
this perverse determination. Justice has yet to be seen to be done in
this
case." http://www.thelancet.com
ALWAYS READ THE LEAFLET
CAMPAIGN
The Medicines and Healthcare products Regulatory Agency (MHRA) and the
Committee
on Safety of Medicines (CSM) Patient Information Working Group have
launched
the report "Always read the leaflet - Getting the best information with
every
medicine". The report is unveiled as part of a programme of talks and
workshops launched by the Department of Health's head for Patients and
the Public.
The report is the culmination of work since 2003 in response to
concerns about
the quality of patient information leaflets (PILs) and their perceived
failure
to meet the needs of patients. The report focuses on strategies to
improve
the quality and accessibility of medicine information and addresses
risk
communication (empowering patients to understand risks and benefits
associated
with medicines). It also delivers new guidance and recommendations that
will
help improve the quality of PILs to benefit patients.

VITAMIN A WARNINGS FOR PREGNANT WOMEN IGNORED
An investigation by Oxfordshire county council's trading standards
department
and birth defects charity BDF Newlife has revealed that many
supplements
fail to warn of the risk of taking vitamin A in pregnancy. After
assessing
60 multivitamin products available between November 2004 and March
2005,
the researchers found one third of the supplements did not carry
vitamin
A warnings. The trading standards department and BDF Newlife are
calling
for compulsory vitamin A warnings on all multivitamin products.
According
to the Chief Executive Officer of BDF Newlife, most women eating a
balanced
diet do not need a vitamin A supplement, unless advised by a doctor or
antenatal
clinic. They should also avoid vitamin A rich foods, such as liver,
kidney,
oily fish, diary products and eggs. http://www2.netdoctor.co.uk/news/index.asp?id=119818&D=20&M=7&Y=2005
NICE DELAYS DECISION ON ALZHEIMER'S DRUGS
The National Institute for Health and Clinical Excellence (NICE) has
requested
more evidence from pharmaceutical companies before publishing the final
draft
of its review of donepezil, rivastigmine, galantamine and memantine for
the
treatment Alzheimer's disease. The Institute's Appraisal Committee met
on
1 June to consider feedback on the first draft consultation from
stakeholder
organizations, together with feedback from individual clinicians and
the
families, friends and carers of those with Alzheimer's disease. At this
meeting
the Committee agreed that, "based on the evidence currently available,
and having taken full account of the response to consultation, they
could not change their original conclusion". This means that NICE has
not issued new
guidance to the NHS on the use of donepezil, rivastigmine, galantamine
and
memantine for the treatment of Alzheimer's disease, and until final
guidance
is issued the existing NICE guidance no. 19 continues to apply.
Responses
to the request for further information will be considered by the
Appraisal
Committee in October 2005
LUNG CANCER MORTALITY IS DECLINING IN MEN BUT NOT WOMEN
The BMJ reports - 23rd July 2005 that mortality due to lung cancer is
now
declining in middle aged men in all new European Union states as well
as
most of the old ones, but it is still increasing among women,
reflecting
earlier trends in tobacco exposure. The research reported shows trends
in
age standardised mortality due to lung cancer in the 35-54 age group
for
all EU member states. The authors emphasise the continuing need for
strong
antismoking programmes for both sexes. http://bmj.bmjjournals.com/cgi/content/full/bmj;331/7510/189
ACTIVITY LEVELS SIGNIFICANT IN BMI AND
ADIPOSITY
IN TEENAGE GIRLS
Preventing the steep
decline
in activity during adolescence is an important method to reduce obesity
according
to the findings of an American study, reported in THE LANCET 16th July
2005.
The study shows that changes in activity levels of US girls during
adolescence
significantly affected changes in body-mass index (BMI) and adiposity.
In
a cohort of 1152 black and 1135 white girls from the USA, who were
followed
up prospectively from ages 9 or 10 to 18 or 19 years. BMI and sum of
skinfold
thickness were assessed annually, whereas habitual activity was
assessed
at years 1 (baseline), 3, 5, and 7-10. http://www.thelancet.com/journals/lancet/article/PIIS0140673605668377/abstract
MANAGING OPHTHALMIC
HERPES ZOSTER IN PRIMARY CARE
In a review article in the BMJ - 16th July
2005,
the author's outline the main points that general practitioners should
keep
in mind when faced with a case of ophthalmic herpes zoster. One out of
every
100 individuals will contract herpes zoster ophthalmicus during their
lifetime.
Doctors should be alert for sight threatening eye complications if skin
lesions
are located in the dermatome of the nasociliary nerve. This area
includes
not only the tip of the nose, but also involves the skin at the inner
corner
of the eye, and the root and side of the nose (Hutchinson's sign) -
According
to the review, all patients with ophthalmic zoster, irrespective of age
or severity of symptoms, should be prescribed oral antiviral drugs at
the first
sign of disease. http://bmj.bmjjournals.com/cgi/content/full/331/7509/147

ROUTINE BCG VACCINATION AT 13 TO CEASE
The Chief Medical Officer has announced changes to
the
BCG vaccination programme, to reflect the changing patterns of TB
infection
in the UK (Not including Northern Ireland.) The routine BCG vaccination
for
TB at age 13 is to stop and instead, the programme will target at-risk
groups,
including neonates in areas where the incidence of the disease is
greater
than 40 per 100,000. The new programme, to be introduced from September
2005,
will identify and vaccinate babies and older people who are most likely
to
catch the disease, especially those living in areas with a high rate of
TB
or whose parents or grandparents were born in a country with a high
prevalence
of TB.
DO BRITISH CHILDREN GET ENOUGH SUNLIGHT?
Research published in the BMJ 9th July 2005
suggests
that skin cancer campaigns such as Sun Smart (www. Sunsmart.org.uk) are
probably
not depriving UK children of sufficient sunlight. Experts have been
suggesting
that less time spent exposed to sunlight reduces opportunities for the
production of Vitamin D with consequent detriment to bone health and
possibly increased
risk of certain cancers and other diseases, including
multiple-sclerosis

DOCTORS AND COMPANY TO BE HELD LIABLE FOR
CONTRACEPTIVE
FAILURE
The BMJ - 25th June 2005 - reports that a court in
Holland
has ruled that 15 women who became pregnant despite using the
contraceptive
implant Implanon are entitled to be paid damages for their
"unintentional
pregnancy." But whether Organon, the Netherlands based company that
marketed
Implanon, or the individual doctors who inserted it are liable remains
unanswered.
The court concluded that both should pay damages unless either can
bring
further evidence. The doctors need to prove that the product was faulty
and
that they inserted it properly, Organon the opposite. To read the

ANTIBIOTIC TREATMENT NOT NECESSARY FOR CHILDREN
WITH
CONJUNCTIVITIS?
Researchers in Oxford have concluded that the use
of
antibiotic eye drops to treat acute infective conjunctivitis in
children
should no longer be recommended as standard clinical practice. Instead,
according
to the research published in THE LANCET On Line - 21st June 2004,
parents
should be encouraged to treat children themselves unless unusual
symptoms
develop, or they persist for more than a week. However, the researchers
acknowledge
that parental concern and the current exclusion policy of many schools
and
nurseries for children with conjunctivitis could make implementation of
a
change in prescription policy difficult. www.thelancet.com
Note: The Medicines
and
Healthcare products Regulatory Agency recently announced that
chloramphenicol
eye drops should be available over-the-counter. It will be the first
antibiotic
to be sold by pharmacists without a prescription in the UK. More
than a million school children have an episode of conjunctivitis every
year
and the cost of current antibiotic prescribing policy is therefore
substantial.
SMOKING AND OBESITY ACCELERATE HUMAN AGEING
People who smoke or are obese are biologically older than slim
individuals
and non-smokers, suggests a study published by THE LANCET online
(Tuesday
June 14, 2005) Researchers in the UK and the USA looked for evidence of
ageing
at a molecular level in smokers and obese individuals. 1122 women from
the
UK aged 18-76 years were recruited onto the study. 119 of the women
were
obese, with a body mass index (BMI) greater than 30, and 85 women had a
BMI
under 20. Non smokers who had never smoked totaled 531. There were 369
ex-smokers,
and 203 current smokers. The investigators measured the concentrations
of leptin and telomere length in blood samples from the women. They
found that
telomere length decreased steadily with age and the telomeres of obese
women
and smokers were much shorter that those of lean women and
never-smokers.
Lean individuals had significantly longer telomeres than women with
midrange
BMIs, who, in turn, had longer telomeres than obese individuals. The
difference
in telomere length between being lean and being obese corresponds to
8·8 years of ageing; smoking (previous or current)

AIRCRAFT NOISE MAY AFFECT CHILDREN'S READING AND MEMORY
Exposure to high levels of aircraft noise could impair the development
of
reading and memory in children, suggests a study published in THE
LANCET
(June 4th 2005.) In the largest study of its kind to date, researchers
in
London assessed the effects of road traffic and aircraft noise on
children's
cognitive development and health. Over 2800 children, aged 9-10 years,
from
89 primary schools located near three major airports-Schiphol in the
Netherlands,
Barajas in Spain, and Heathrow in the UK-took part in the study. The
investigators
assessed aircraft and road traffic noise levels around the schools, and
compared these levels to the results of cognitive tests and health
questionnaires.
Pooling the data from the three countries, the researchers found
exposure
to aircraft noise impaired reading comprehension, even after adjustment
for
socioeconomic differences between high-noise and low-noise schools.
Reading
age in children exposed to high levels of aircraft noise was delayed by
up
to 2 months in the UK and by up to 1 month in the Netherlands for a 5
decibel
change in noise exposure. Road traffic noise did not have an effect on
reading
and was unexpectedly found to improve recall memory. Increased exposure
to
both aircraft and road traffic noise was associated with increased
stress
in children and reduced quality of life.http://www.thelancet.com
NICE GUIDANCE FOR
OCCLUSIVE
VASCULAR DISEASE CRITICISED
The British Cardiac Patients Association (BCPA),
Sanofi-aventis
and Bristol-Myers Squibb have all issued press statements expressing
disappointment
at the latest NICE guidance on management of occlusive vascular disease
(OVE).
They believe that too much emphasis has been placed on the use of
aspirin
in that it only recommends the use of clopidogrel (Plavix), for
instance,
where the patient is intolerant of aspirin. No guidance is offered in
the
event of patients suffering further vascular events despite taking
aspirin
therapy. Both the BCPA and the pharmaceutical companies fear that many
patients
will not, therefore, receive optimised treatment for the leading cause
of
death in the UK despite the fact that clopidogrel costs only
approximately
£1.00 per day. Clopidogrel is said to have proven benefit over
aspirin
in the prevention of secondary atherothrombotic events after recent
myocardial
Infarction, recent ischaemic stroke and in patients with established
peripheral
arterial disease. The NICE guidance, it is suggested, does not reflect
the
established clinical value of these known benefits. NICE is criticised
further
because its guidance treats myocardial infarction, ischaemic stroke and
peripheral arterial disease as separate entities even though it agrees
that these are
all manifestations of the same underlying process - atherothrombosis.
By
approaching each manifestation individually it ignores the cross-risk
that
exists between all of these conditions and the likelihood of patients
falling
victim to any of them. Please click
here to email for information.
Note: In response to this criticism, NICE tell
us
that they looked carefully at all the evidence showing how well
clopidogrel
worked in comparison to aspirin for preventing heart attacks and
strokes.
"The evidence showed that clopidogrel is as clinically effective as
aspirin,
but since it is more expensive it would not be good value for money for
the
NHS to replace aspirin as the standard treatment of choice for people
at
risk of a second heart attack or stroke."
ASPIRIN
CONTRA-INDICATED FOR THE OVER 70s?
According to the findings
of
an Australia study reported in the BMJ - 20th May 2005, epidemiological
modelling
suggests that any benefits of low dose aspirin on risk of
cardiovascular
disease in people aged 70 or over are offset by adverse events. The
researchers
carried out epidemiological modelling in a hypothetical population to
investigate the routine use of low dose aspirin in people aged 70 or
over without overt
cardiovascular disease. They used reference populations of men and
women
in 2000 from state of Victoria, Australia. The population modelled
consisted
of 10,000 men and 10,000 women aged 70-74 with no cardiovascular
disease.
The main outcome measures used in the study were first ever myocardial
infarction
or unstable angina, ischaemic or haemorrhagic stroke, and major
gastrointestinal
haemorrhage. Health adjusted years of life lived was also an outcome
measure.
The results found that the proportional benefit gained from the use of
low
dose aspirin by the prevention of myocardial infarctions (-389 in men,
-321 in women) and ischaemic stroke (-19 in men and -35 in women) is
offset by
excess gastrointestinal (499 in men, 572 in women) and intracranial (76
in
men, 54 in women) bleeding. The results in health adjusted years of
life
lived (which take into account length and quality of life) are
equivocal
for aspirin causing net harm or net benefit. http://bmj.bmjjournals.com/cgi/content/abstract/bmj.38456.676806.8Fv1
FURTHER
EVIDENCE OF LATE DIAGNOSIS OF HIV INFECTIONS IN UK
BMJ early online (16TH May
2005)
publishes a case review of new HIV diagnoses in the UK and Ireland,
looking
at the occurrence of late diagnosis and associated features and to
determine
if patients had prior presentations that may have been related to HIV
infection.
Data was collected via questionnaires, which were sent to adult HIV
care
providers in the UK and Ireland. Data on a total of 977 patients
presenting
with new diagnosis of HIV infection in January-March 2003 was
collected.
A total of 301 patients (33%) presented late - this was more common in
both
older patients (adjusted odds ratio per increase in age group 1.68, 95%
CI
1.42-1.98, p=0.0001) and in black Africans (1.66, 1.05-2.62, p=0.03).
Overall,
401 (41%) were diagnosed via routine screening (e.g. sexual health,
genitourinary or HIV clinic) - diagnosis in this way was associated
with a lower chance
of late diagnosis. A high proportion of patients (17%) sought medical
care
with symptoms in the preceding 12 months but remained undiagnosed. The
authors
conclude that this study provides further evidence of the late
diagnosis
of HIV infection, following national trends reported by the Health
Protection
Agency. They say that improving the offering and uptake of HIV testing
both
as part of routine screening and as indicated by associated medical
conditions
should reduce the number of undiagnosed infections.

MRI COMBINED WITH
MAMMOGRAPHY
MORE EFFECTIVE
Annual screening, using magnetic resonance imaging
(MRI)
and X-ray mammography, is the best way to detect breast cancer in women
that
have a high genetic risk of the disease, according to a study published
in
THE LANCET online - Monday May 16, 2005. Researchers at The Institute
of
Cancer Research in London looked at 650 high risk women from 22
radiology
and genetic centres throughout the UK. The women, aged 35 to
49
years, were offered annual MRI and X-ray mammography for between two
and
seven years. MRI was found to be nearly twice as sensitive as X-ray
mammography
in detecting breast. However, when mammography and MRI were combined,
94%
of tumours were picked up in the women.
The researchers also found that MRI screening was particularly
effective for women known to
carry the BRCA1 gene mutation, detecting 92% of tumours in women
carrying this gene whereas X-ray mammography only detected 23%. Go to http://www.thelancet.com to view

DOCTORS CALL FOR
HEPATITIS
B JAB FOR ALL CHILDREN
The
British
Medical Association have advised that immunisation of babies against
hepatitis
B could prevent suffering in patients and save the NHS million of
pounds in
treating people with the virus. In 2003, there were 1,151 new cases, a
135%
increase on the 1992 figures, mostly among 15- to 44-year-olds. ABD
Member,
Dr Sam Everington, Deputy Chairman of the BMA has been reported in the
national
press endorsing the proposal. The Department of Health is said to be
considering
whether hepatitis B immunisation needed strengthening or expanding and
confirmed
that in the UK, prevalence of chronic hepatitis B infection is one of
the lowest in the world. Also, the incidence of acute hepatitis B
remains relatively
stable and low.
AMIAS APPROVED FOR CHRONIC
HEART
FAILURE WITH LVSD IN SCOTLAND
Amias (candesartan cilexetil),
the
angiotensin-receptor blocker (ARB), currently used in the treatment of
essential
hypertension, has been approved by The Scottish Medicines Consortium
(SMC)
for the treatment of patients with chronic heart failure (CHF) and left
ventricular
systolic dysfunction (LVSD) as add-on therapy to an
angiotensin-converting
enzyme inhibitor (ACEi), or for those patients unable to tolerate an
ACEi.
Apart from lengthening the lives of patients with CHF with LVSD, the
use
of Amias is expected to reduce significantly the number of
hospitalisations
due to heart failure. In England alone, a million in-patient bed days
are
due to heart failure and historically, the condition has a poor
prognosis
with just under 40% of CHF patients dieing within a year of diagnosis.
Survival
rates are worse than those from cancer of the breast, uterus, bladder
and
prostate. Added to this, the annual cost of heart failure to the NHS in
the
UK is just over £625 million, consuming between 1-2% of the
national
NHS budget. In Scotland, patients with CHF and LVSD occupy an estimated
140,000
bed days per annum in NHS hospitals and it is thought that candesartan
may
save as many as 29,500 of them each year. Please click here to email for more

AVOIDANT PARURESIS (AP)
Shy Pee,
Bashful
Bladder or Psychogenic Urinary Retention is a condition that may affect
7%
of the population. The Diagnostic and Statistical Manual (DSM IV)
refers
to this condition as a social phobia. ABD Member, Prof. Alex Gardner,
is
involved in raising awareness of the condition and will be addressing
some
of the issues surrounding paruresis at an international conference in
Budapest
from 11th May- 14th May2005. He will be explaining the depression,
stress
and anxiety caused by the condition conjointly with the theme of humour
and
healing. His paper explores some of the possible psychological issues
contributing
to this condition and the factors relating to: a) How the concepts and
constructs
of paruresis, learned and stored from the past, are accessed, b) The
dynamics
of approach and avoidance behaviours in the present and c) The role of
expectations
about the future The paper also deals with the coping strategies used
by
paruretics and outlines the therapies employed to deal with it. For

-14th May 2005. The aim is to encourage mothers to feel proud of
breastfeeding,
in support of which they have produced a new poster - 'Breastfeeding
makes
a difference right from the first feed' This is supported by an
information
sheet listing the reasons why mothers should be proud of giving their
child
the best possible start in life. Please click here to email for copies
of
the poster and information sheets.
VACCINE
AGAINST CERVICAL CANCER AND GENITAL WARTS
Trials of
a
vaccine for human papillomavirus (HPV) have proved promising according
to
a paper in THE LANCET ONCOLOGY (April 2005). Investigators looked at
healthy
women aged 16-23 from Brazil, Europe and the USA. The participants were
not
pregnant, had no previous abnormal cervical smears and reported a
history
of four or fewer partners. 277 women were randomly assigned to the
vaccine
and 275 to a placebo. The incidence of persistent infection or disease
with
HPV 6, 11, 16, or 18 fell by 90% in those assigned the vaccine. The
vaccine
was 100% effective against precancerous cervical lesions and genital
warts
associated with the four HPV types. There were no vaccine related
serious
adverse events. Please click here to email for a PDF of the research
paper.
LUPIN FLOUR A RISK TO THOSE
WITH
P EANUT ALLERGY
A report in THE LANCET (9th April 2005) concludes
that
adults and children with an allergy to peanuts could also be allergic
to
lupin flouR - a substance that is used in some European countries as a
potential
replacement for soya flour. Food manufacturers in these countries are
using
it in certain specialty breads, bakery goods and catering foods, and a
small
number of these are finding their way into the UK. The authors suggest
that
people with a peanut allergy should avoid all products containing lupin
flour
until they can be specifically tested to see if they are susceptible. http://www.thelancet.com
EU
VITAMIN
DIRECTIVE OVER RULED
The EU
directive
that could ban thousands of popular vitamin and mineral supplements has
been
declared illegal by a European judge. The new rules governing vitamins
and
minerals are due to come into effect on 1 August 2005 and are designed
to
improve the safety and efficacy of products sold by the industry. Under
the
directive, only named ingredients with proven scientific benefits have
been
included on an EU "positive" list of approved substances that would be
allowed
in health supplements. More than 300 different vitamins and minerals
are
not on the positive list, leaving 5,000 supplements which will be
banned
if the proposals become law. However, according to the report, the
advocate
general at the European Court of Justice (ECJ) gave an advisory opinion
that
the directive, as it stands, infringes basic EU principles. He said
that
the current proposals lacked clear rules for the European Commission to
follow
when deciding whether or not to include an ingredient on the
positive
list. The advocate general's opinion that the directive is "invalid" is
not
binding, and the full ECJ will rule on the case in July, but the court
normally
follows his opinion. The advocate general however upheld the concept of
EU
legislation on health supplements, saying that the proposals needed to
be
reworked rather than scrapped. For full story, please click on http://www2.netdoctor.co.uk/news/index.asp?id=118471&D=6&M=4&Y=2005
POLITICAL POINT-SCORING OVER
MRSA
IGNORES THE REAL ISSUE
An
editorial
in THE LANCET - 2nd April 2005 suggests that political point-scoring
over
policies to control MRSA (meticillin-resistant Staphlococcus aureus)
confuses
cleanliness with the real failure in UK hospitals - poor hand hygiene
and
inadequate use of gloves. Evidence shows that housekeeping programmes
are
unlikely to have an overall effect on transmission of MRSA unless these
essential
infection-control practices are prioritised. Please click here to view the
editorial.
EU IS
SEEKS
SUGGESTIONS ON HOW TO INCREASE BIRTH RATE
By 2030
every
two economically active people in the EU will have to take care of one
inactive
person, according to a consultation paper issued by The European
Commission
and reported in The BMJ 26th March 2005. It is estimated that the EU
will
have 18 million fewer children and young people than today, and in the
five
largest countries of the EU, population increases over the next 45
years
will be seen only in the United Kingdom (8%) and France (9.6%). The
commission
warns that never before in history has there been economic growth
without
population growth and that the implications of the changes will reach
far
wider than just the status of older workers, pension reform, and the
provision
of health care. The commission is asking what innovative measures can
be
taken to support an increase in the birth rate. Please click on the

RESEARCHER
TO BE SACKED AFTER REPORTING HIGH RATES OF ADHD
The BMJ -
26th
March 2005 reports that a US researcher who said that doctors and
psychologists
may be over diagnosing attention deficit hyperactivity disorder (ADHD)
in
children has been placed on administrative leave "with intent to
terminate"
her employment. The move came after charges of scientific misconduct
against
her, and her computers have been seized. Dr Gretchen LeFever's work has
been
controversial, according to the report. . She first made headline news
in
1999 when she reported that 8% to 10% of elementary school pupils in
southeastern
Virginia were being prescribed drugs for ADHD, a percentage two to
three
times the estimated national average (American Journal of Public Health
1999; 89:1359-64). Please click here for the BMJ report. http://bmj.bmjjournals.com/cgi/content/full/330/7493/691?etoc
