Who decides what’s good for my baby?
The
extraordinary developments in human genetics provide possibilities for the
prevention, diagnosis and treatment of inherited monogenetic diseases as well as
a wide spectrum of more common conditions which involve complex genetic and
environmental interplay. The question to be considered is: how are we to deal
with the new techniques of human genetics?
How can we reap the fruits and also steer clear of the dangers? The author
discusses three alternatives: the Pure Nazi model in which the state chooses a
gene pool and kills those who do not fit in; the Pure Eugenics model in which
the state achieves the same ends, but through forced sterilisation, and the
Liberal model, in which individuals are free to make decisions to control their
genetic contributions. The author argues against a ban on any form of research,
proposing, instead, that individuals be free to make their own choices, there is
individual freedom and there is no socially decided ideal of what is ‘good’ or
‘healthy’.

Organ transplantation and the legal framework
Barely 30 years ago, organ transplantation was an essentially
unsuccessful experimental procedure conducted in pioneering medical research
centres. Today, renal transplantation is a widespread and routine procedure for
an estimated 35,000 patients worldwide each year. However, this success led to
an ever increasing demand, a shortage of donors, and the commercialisation of
the donor supply. “What policies should be instituted to help increase the
availability of these precious tissues?” The author, who earlier wrote an essay
in defence of a commercial market, has reworked his ideas quite substantially.
He answers the question in the context of the Transplantation of Human Organs
Act, 1994, while examining its implications and the consequences of
commercialisation - in terms of organ availability, social justice, exploitation
and so on.

Sorry, out of stock
Drugs offer a simple, cost
effective solution to many health problems, provided they are available,
affordable, and properly used. However, effective treatment is lacking in poor
countries for many diseases, including African trypanosomiasis, Shigella
dysentery, leishmaniasis, tuberculosis, and bacterial meningitis. Treatment may
be precluded because no effective drug exists, it is too expensive, or it has
been withdrawn from the market. Moreover, research and development in tropical
diseases have come to a near standstill. The article focuses on the problems of
access to quality drugs for the treatment of diseases that predominantly affect
the developing world: (1) poor quality and counterfeit drugs; (2) lack of
availability of essential drugs due to fluctuating production or prohibitive
cost; (3) need to develop field- based drug research to determine optimum
utilisation and remotivate research and development for new drugs for the
developing world; and (4) potential consequences of recent World Trade
Organization agreements on the availability of old and new drugs. These problems
are related, and a result of the fundamental nature of the pharmaceutical market
and the way it is regulated.

The infant food code
This study of the
prevalence of violations of the international code of marketing of substitutes
for breast milk, interviewed 1,468 pregnant women, 1582 mothers of infants aged
less than six months, and 466 health workers, at 165 health facilities in one
city in each of Bangladesh, Poland, South Africa, and Thailand. Women were asked
whether they had received free samples of breast milk substitutes, bottles, or
teats, and health workers were interviewed to assess whether the facility had
received free samples, how they had been used, and whether gifts had been given
to health workers by companies manufacturing or distributing breast milk
substitutes. Twenty- six per cent of Thai mothers reported receiving free
samples, compared to 1 out of 385 mothers in Dhaka. Eight to 50% health
facilities had received free samples which were not being used for research or
professional evaluation; two to 18% health workers had received gifts from
companies involved in the manufacturing or distribution of breast milk
substitutes. At 15 to 56% of the health facilities, information violating the
code had been provided by companies and was available to staff.

Regulated research
This report comments on
controversial proposed U S government regulations governing research of people
with retardation, mental illness and brain disease. While they would provide
protection by regulating all such research, and requiring the involvement of
people with the problem, or advocacy organisations, they would also legitimise
research posing greater than minimal risk-benefit to subjects’ even though the
subjects cannot give their informed consent, if their guardians give consent.

the Network on Ethics and Intellectual Disability. 1999; 4(I): I,6.
Is informed consent always
necessary?
Researchers must get specific informed consent of’
patients in clinical trials, but doctors may sometimes offer the same therapy
without such consent, in the name of innovation. The authors suggest that in
many randomised. controlled trials, patients’ participation should be presumed
by their general consent for treatment. Criteria for a waiver: all treatments
may be offered outside the trial without specific informed consent; they do not
involve more than minimal additional risk compared to the alternatives; genuine
equipose exists; no reasonable person would prefer one treatment to the other ;
patients know that the institution uses the guidelines, and the institutional
review board approves. These criteria should be interpreted narrowly and applied
conservatively. The authors hold that this will not lead to patient exploitation
by researchers. Informed consent is not an ideal in itself’ but is meant to
ensure that the patient’s right to selfdetermination is respected. Studies show
patients rarely understand consent forms and randomisation. The most effective
protection against exploitation comes from conscienlious institutional review.
Boards approving questionable studies on the assumption that the informed
consent process will protect research subjects are not doing their job. The
current situation also prevents many small but meaningful improvements in the
quality of care when there is no reason to believe that the patient has any
preference regarding participation in research.

controlled trials? The New England Journal of Medicine 1999: 340 (10)
More on the AZT trials and research ethics.
This comment
on the controversial placebo- controlled trials clinical for maternal- foetal
transmission of HIV may raise further debate. The author examines the ethics of
AZT- equivalence and placebo- controlled trials in developing countries. Some of
the points rnade: equivalence trials may result in fewer deaths among trial
participants and arrive at inconclusive answers, but a placebo controlled trial
will provide clearer answers, thus providing more help to the general population
even if fewer trial participants are benefited. Finally, discussants in the
debate “have assumed that it is straightforwardly a good thing to reduce child
deaths caused by perinatal transmission.... the brutal truth .._ is that the
more children they save, the worse these treatments will tend to make the AIDS
orphan problem, for whom the only option is international adoption.

Why physician-assisted suicide ?
On October 27,
1997, Oregon, USA, legalised physician-assisted suicide. Data on the 22
terminally ill Oregonresidents who received prescriptions for lethal medications
under the Oregon Death with Dignity Act and who died in 1998 were compared to
those who died from si1nilar illnesses but did not receive such prescriptions.
The study concluded that during the first year of legalised physician assisted
suicide in Oregon, the decision to request and use a prescription for lethal
medication was associated with concern about loss of autonomy or control of
bodily functions, not with fear of intractable pain or concern about financial
loss. In addition, the choice of physician- assisted suicide was not associated
with level of education or health insurance coverage.

conclusion; an overview of the judicial, legislative and administl- ative
systems.
The ethics of biomedical research: an international perspective Baruch A.
Brody. 386 pp. New York, Oxford University Press, 1998.The book examines how
the ethics of various areas of biomedical research are addressed by countries in
North America, Western Europe, and the Pacific. It contains a compilation of 38
critical international, transnational, and national (US, British, German,
French, Canadian, Australian, and Japanese) policies, regulations, and
guidelines, from the Nuremberg Code (1947) through the revised version of the
World Medical Association’s Declaration of Helsinki, as well as less well
publicised policies developed by the Council for International Organizations of
Medical Sciences addressing such issues as the vulnerability of research
subjects in less affluent societies, and the need to be sensitive to different
cultures.
