(1) TRAUMATIC LIFE EVENTS AROUND THE TIME OF
CONCEPTION MAY MAKE IT MORE LIKELY THAT YOU
HAVE A GIRL

(Severe periconceptional life events and the sex ratio in offspring:
follow up study based on five national registers)
http://www.bmj.com/cgi/content/full/319/7209/548

Psychological stress associated with severe life events around the time
of conception seem to lower the odds of having a male baby, suggest
researchers in a paper in this week's BMJ. Dr Dorthe Hansen, from
the John F Kennedy Institute and the Danish Epidemiology Science
Centre and colleagues from the Centre for Research in Health and
Social Statistics and the Danish Epidemiology Science Centre
analysed the male to female ratio of 3072 babies who had been
conceived amidst traumatic events. They found that the proportion of
boys was 49 per cent as opposed to 51.2 per cent in their control
group.

Hansen et al conclude that psychological stress related to severe life
events may alter the sex ratio of offspring through changes in sexual
activity, changes in hormones around the time of conception, reduced
semen quality or an increased rate in miscarriage of male babies.

(2) DRUG COMPANIES RESPONDED POORLY TO REQUESTS
FOR INFORMATION FROM DOCTORS IN PAKISTAN

(Responses from pharmaceutical companies to doctors' requests for
more drug information in Pakistan)
http://www.bmj.com/cgi/content/full/319/7209/547

Many doctors in the developing world do not receive adequate or
appropriate responses then they request product information from
drug companies, claim doctors from Pakistan in this week's BMJ.
Assad Hafeez from Khan Research Laboratories Hospital in
Islamabad and Zafar Mirza from The Network for Rational Use of
Medication in Pakistan believe that the decision to respond to a
request for more information seems to depend on how favourable it
might be to the interests of the company.

The authors asses how seriously pharmaceutical companies take their
responsibility to provide information on request, by recording the
promptness, nature and adequacy of their replies to doctors. They
found that of 152 requests to 45 companies (made by 24 doctors in
different cities in Pakistan), only just over a quarter (26 per cent; 39
responses) received a response. Of these 39 responses only six met
the WHO criteria for optimal drug information.

Hafeez and Mirza also found that the specialists who made requests
received twice as many responses as the general practitioners, which
they claim is because "specialists are seen as opinion formers and
more important to the companies that general practitioners." They
conclude that objective drug information is essential for effective
prescribing and they call upon the Pakistan ministry of health,
academic institutes and non-governmental organisations to make
available unbiased information on drugs.
