All rapid responses
Dear Editor,
Thank you for your eloquent response to my comments on the research
content of the British Medical Journal.
It certainly has not 'escaped' my attention that 40% of the world's
children live in malaria-endemic conutries or that there are over 1
million deaths from malaria each year, or that the World Health
Organisation is running a decade long campaign called 'Roll back Malaria'
(www.who.int/). However, given that there is only 1 research paper
published fully this week i think the topic alone is not justification
enough.
Overall i enjoy the 'themed issues' in the BMJ but i think they can
be overblown and there is a delicate balance to be struck. Once again i
look to the New England journal's own themed issues, usually begining with
some excitingly lucid and incisive commentry in the 'perspectives
coloumn'.
Is it not a fallacy to suggest that a journal is 'international'
because it publishes papers authored in foreign countries? Surely a
journal is trully international by virtue of publishing papers worthy of
the world stage.
The altruistic way in which the BMJ helps to give a 'hand-up' to
foreign authors is commendable and i would generally support it given that
we can only really flourish when we look outwith ourselves.
kind regards,
Michael Reschen

Dear Dr Reschen,
Thanks for your message. I'm sorry you found the study on malaria in
the Yemen uninteresting. I'm sure it cannot have escaped your notice that
this was published in the context of a theme issue focussing on health in
the Middle East, nor that malaria remains one of the world's greatest
killers and is therefore of huge importance to health care in this and
other regions of the world. We expected to get flack from UK readers about
running this theme issue, given consistent feedback from reader surveys
and focus groups that coverage of international health issues is not
popular. Tessa Richards and Christiane Rehwagen said as much in their
editor's choice. Interestingly, several UK readers have posted responses
congratulating us on the issue. We feel that coverage of health in this
important region is entirely justified in an international journal,
particularly at the current time, and we were pleased to be able to
publish this research paper from Yemen. One aim of our theme issues has
been to help build research capacity in parts of the world where this is
lacking.
Thank you for giving me the opportunity to point out that, for what
it's worth, the BMJ's impact factor rose this year for the first time in
several years, from around 7 to over 9. As for the lunacy of our research
publications, we (and I am sure our authors and peer reviewers) would be
keen to hear any coherent critiques of the research we publish - this as a
crucial part of peer review. I invite the hapless SHOs you mention,
yourself included, to pass these onto us via rapid responses. The most
interesting of these will be published as letters in the journal.

Dear Editor,
Why are you including such utterly uninteresting studies? This study
might yield one or two interesting statistics that may be of use to their
government but it hardly warrants publication in the British Medical
Journal. It is sad to see such a British icon, the BMJ in decline. No
wonder its 'impact factor' has been steadily dropping.
The BMJ editors seem to be complicit in Britain's anti-intellectual
culture. There seems to be some anxiety about including more scientific or
detailed articles for fear of alienating GPs. I think this is a mistake
and only serves to leave GPs at a slight disadvantage overall. Afterall
GPs may be historically rooted in managment tasks which ought to be
performed elsewhere, but they also need to treat physical and mental
illness. Sadly the most informative sections in the BMJ are the drugs
adverts - they're a useful way of keeping up to date on the latest brands
being pushed by drugs companies. If i want medical news there are plenty
of better resources and if i want serious medical information i look to
the New England journal or the Lancet.
I'm not convinced the editors of the BMJ have insight into the
decline of their journal or perhaps they are just quite happy for it to be
a vehicle for English or foreign authors who need to get on the
publication ladder.
Lamentably every now and then some hapless SHO presents a research
article from the BMJ at one of our grand rounds and is instantly torn to
shreds over the sheer lunacy of its publication. Perhaps you should attach
a warning that BMJ articles are not intended for peer review - although i
am puzzled as to the reasoning of your own peer reviewers?
I'm sure my words will evoke a swift rebuttal but i believe there is
a kernel of truth within my sentiments.
I do however like the careers section and the BMA news!
kind regards

Al-Taiar et al reported important data on children admitted with
severe malaria in 2 public health facilities. The study populations were
residents of well-known malaria-endemic areas 1. Severe malaria accounted
for 6.6% (808/12301) of total paediatric admissions and case fatality rate
(CFR) 3.2%(26/808). The study did not report on the proportion of malaria
deaths of the total hospitals’ child deaths. Counting child death by cause
is an important initial step to plan, implement and monitor child survival
interventions 2.
Six-year period data (2000-2005) of Al-Sabeen hospital, the major
paediatric public health facility in Sana’a, the Capital of Yemen, showed
that severe falciparum malaria is the 4th important cause of child
admission and death outside the neonatal period (after pneumonia,
diarrhoea and meningitis). During this period 18780 children were
admitted, 746 (4%) had severe falciparum malaria (less severe cases are
usually treated on outpatient basis). There were 91 severe malaria deaths
(CFR 12.2%), 4 times higher than that reported by Al-Taiar et al (3.2%).
The hospital policy is to treat all severe malaria cases with quinine
infusion, and other supportive management according to the WHO guidelines.
Possible explanation for the wide difference in CFRs may be due to partial
immunity maintained by repeated malaria exposure of the study populations.
In the highlands, malaria attacks children that have unprepared immune
system.
During the 6-year period, there were 1612 child deaths in Al-Sabeen and
malaria deaths accounted for 5.7%. It accounted for 4.2%(25/591),
4.7%(23/494), and 8.2%(43/527) in 2000-01, 2002-03, and 2004-05 periods,
respectively. This may indicate significant rise in malaria deaths at the
community level. The national average proportion for child death caused by
malaria is estimated at 7.5% in 2000 3.
In poor countries, including Yemen, late hospital attendance of children
with severe malaria, usually when alarming neurological symptoms appear,
is perhaps the most important risk factor for malaria death indicating
that simple and cost effective interventions at community level should be
adopted.

Importance of neurological presentation of malaria in Africa
It is very misleading of This week in the BMJ to describe the
findings of this study of severe malaria from Yemen(1) as "in contrast to
Africa, where severe anaemia and respiratory distress are better
predictors of fatal outcome [than neurological signs]" . The study itself
refers to "some studies in Africa, however, where respiratory distress
without neurological signs is a strong predictor of mortality". Two
studies are referenced, one did not compare outcomes between these
groups.(2) In the other, a large study from Kenya,(3) it is true that
respiratory distress alone had a higher mortality rate than impaired
consciousness alone, but three times as many children died with impaired
consciousness (n=38) than with respiratory distress without coma (n=13).
The highest mortality rate was in the group with impaired consciousness
and respiratory distress (31%). Those with severe anaemia alone had the
lowest mortality rate (1.3%). Other studies from Africa have shown that
profound coma, respiratory distress and hypoglycaemia are the most
important predictors of death in severe malaria.(4-6) Severe anaemia
without the presence of the other two features has a low mortality in
units able to promptly correct the anaemia.
Anyone who has worked in a paediatric unit in Africa will recognise
cerebral malaria as the dreaded presentation of severe malaria, the more
so when the child has laboured breathing due to the accompanying acidosis.
