(1) SERIOUS PHYSICAL ILLNESS LINKED TO
SUICIDE IN LATER LIFE

(Burden of illness and suicide in elderly people:
case-control study)
http://bmj.com/cgi/content/full/324/7350/1355

Most people who commit suicide late in life suffer from
depression, but the role of physical illness is less clear. A
study in this week's BMJ finds that serious physical illness
also carries an increased risk of suicide in elderly people.

Researchers in Sweden examined the records of 46 men
and 39 women, aged 65 years and over, who had
committed suicide. They compared these with 84 men and
69 women of the same age, living in the same area
(controls). Interviews were also conducted with relatives of
the suicide victims and control persons.

They found that impaired vision, neurological disorders,
and malignant disease were all independently associated
with suicide. When the sexes were analysed separately,
serious physical illness seemed to be a stronger predictor in
men than in women.

Many elderly people who commit suicide consult their
doctor a short time before their death, but many fail to
communicate their despair, say the authors. Further
research should focus on the detection and treatment of
depression and suicidal ideation in the context of physical
disease, they conclude.

(2) PROBIOTICS MAY PREVENT ANTIBIOTIC
ASSOCIATED DIARRHOEA

(Probiotics in prevention of antibiotic associated diarrhoea:
meta-analysis)
http://bmj.com/cgi/content/full/324/7350/1361

(Editorial: Managing antibiotic associated diarrhoea)
http://bmj.com/cgi/content/full/324/7350/1345

Probiotics (microbes that protect their host and can
prevent disease) can prevent diarrhoea associated with the
use of antibiotics, finds a study in this week's BMJ.

Researchers at the Hammersmith Hospital in London
reviewed nine trials carried out to study the benefits of
probiotics in the prevention of antibiotic associated
diarrhoea. In all nine trials, the probiotics were given in
combination with antibiotics and the control groups
received placebo and antibiotics.

They found that probiotics are useful in preventing
antibiotic associated diarrhoea. In particular, the yeast S
boulardii and three strains of Lactobacillus have the
potential to be used in this situation.

Commercially available strains are being marketed in
capsules and yoghurt based drinks, but these were not
tested in the above trials and their potential benefit needs
further investigation, say the authors.

A large trial looking at the efficacy of probiotics in
preventing antibiotic associated diarrhoea, particularly in
elderly patients, with an emphasis on the optimal dose and
cost benefits is needed, they conclude.

(3) RATES OF GENITAL HERPES INFECTIONS RISE

(Longitudinal study of genital infection by herpes simplex
virus type 1 in western Scotland over 15 years)
http://bmj.com/cgi/content/full/324/7350/1366

Genital infections with Herpes simplex virus type 1
(HSV-1) have risen in western Scotland over the last 15
years, particularly among young women, finds a study in
this week's BMJ.

Researchers reviewed all genital samples of herpes simplex
processed between 1986 and 2000 at the West of
Scotland Specialist Virology Centre.

Of the 3,181 swabs testing positive for the virus, 63%
were from women and 37% were from men. Twenty-nine
per cent of patients were aged 21-25 years. In
1986-1988, 33% of all positive swabs were due to
HSV-1, rising progressively to 56% in 1998-2000.

Both the number and percentage of HSV-1 infections have
risen, say the authors. Genital infection with HSV-1 is also
strongly associated with being young (aged less than 25
years) and being female.

Most new cases of genital HSV-1 infection are likely to be
due to orogenital transmission, but there is no evidence
suggesting that oral sex practices have changed
substantially, say the authors. The occurrence of HSV-1
infection in women is unexplained.

These results suggest that counselling and clinical
management strategies may need to be revised, say the
authors. Preventive strategies for genital herpes should
focus on the risk of unprotected orogenital intercourse,
which is frequently perceived as "safe" in the context of
sexually transmitted infections, they conclude.

(4) GOVERNMENTS COMMITTING "PUBLIC HEALTH
MALPRACTICE" OVER FLOUR FORTIFICATION

(Editorial: Delaying folic acid fortification of flour)
http://bmj.com/cgi/content/full/324/7350/1348

The failure of European governments, including the United
Kingdom, to fortify flour with folic acid has allowed a
continuing epidemic of preventable human illness,
according to an editorial in this week's BMJ.

Fortification could save as many lives as are lost each year
in vehicle crashes, writes Professor Godfrey Oakley of
Emory University in the United States. Yet in Europe,
fortification has been delayed because of erroneous
speculation of possible harm for elderly people.

Recent evidence indicates that fortification improves the
lives of adults, including elderly people, and that it is safe.
In 1998 - the year in which fortification was made
mandatory in the United States - deaths from stroke and
heart attack declined by 3.4%.

Although fortification of flour is long overdue in the United
Kingdom and the remainder of Europe, the UK board of
the Food Standards Agency recently decided against
mandatory folic acid fortification.

Ministers should not accept this recommendation, argues
the author. Rather, they should follow the advice of the
Department of Health committee on medical aspects of
food and nutrition policy and require universal fortification
of flour with folic acid. This prudent action would improve
the health of children and adults.

Rare is the opportunity to implement a sustainable,
inexpensive, and effective intervention to prevent major
human diseases, says the author. Folic acid fortification of
flour is one of those rare opportunities. Governments that
do not ensure that flour is fortified with folic acid are
committing public health malpractice, he concludes.

(5) MEDIA UNDERMINE EFFORTS TO TACKLE
NICOTINE ADDICTION

(Editorial: The power of the press in smokers' attempts to
quit)
http://bmj.com/cgi/content/full/324/7350/1346

Inaccurate media reports surrounding the safety of new
smoking cessation drugs are undermining the treatment of
nicotine addiction, according to an editorial in this week's
BMJ.

Professor Linda Ferry presents two scenarios that illustrate
the struggle between the press and medical experts to
investigate and report concerns about the safety of new
drugs for smoking cessation, and the effect this struggle has
on reported attempts to quit smoking.

In the United Kingdom, bupropion hydrochloride (Zyban)
was heralded by the media as a wonder drug when it was
released in 2000. Not surprisingly, smokers queued up in
waiting rooms, expecting their tobacco addiction to be
vanish with this new pill.

The public enthusiasm changed abruptly in February 2001
when a London newspaper profiled a few dramatic reports
of deaths in smokers using bupropion. Although experts
remain convinced of the safety of bupropion, the demand
for treatment has declined.

A similar shift in public opinion followed media reports in
the United States about an increased risk of heart attack
associated with nicotine patches. A subsequent trial
showed that patches were safe to use, specifically in
patients with heart disease, but many smokers still believe
the original media messages that "if I use a patch and
smoke even one cigarette, I might have a heart attack."

Clinicians should give clear messages to their patients that it
is much safer to use either of these drugs to help their
attempts to quit than to continue smoking, says the author.
Unfortunately, much damage has been done.

Tobacco treatment specialists and public health agencies
need to refute the inaccuracies of the media and present a
clear picture of the enormous problem of preventable
disability and the 120,000 tobacco related deaths a year
from the 13 million smokers in the United Kingdom, she
concludes.
