An evaluation of clinical indicators for severe paediatric illness.
To help reduce paediatric morbidity and mortality in the developing world, WHO has developed a diagnostic and treatment algorithm that targets the principal causes of death in children, which include acute respiratory infection, malaria, measles, diarrhoeal disease, and malnutrition. With this algorithm, known as the Sick Child Charts, severely ill children are rapidly identified, through the presence of any one of 13 signs indicative of severe illness, and referred for more intensive health care. These signs are the inability to drink, abnormal mental status (abnormally sleepy), convulsions, wasting, oedema, chest wall retraction, stridor, abnormal skin turgor, repeated vomiting, stiff neck, tender swelling behind the ear, pallor of the conjunctiva, and corneal ulceration. ⋯ Overall, the mortality risk associated with having at least one sign was 6.5 times higher than that for children without any sign. While these signs are useful in identifying a subset of children at high risk of death, their validation in other settings is needed. The training and supervision of health workers to identify severely ill children should continue to be given high priority because of the benefits, such as reduction of childhood mortality.

Non-governmental organizations in international health: past successes, future challenges.
Non-governmental organizations, or NGOs, are increasingly instrumental to the implementation of international health programs. Following an overview of current conditions in global health and the problems that could be targeted by NGOs, this article describes the activities and philosophies of several representative approaches in this sector. The attributes of NGOs that increase their potential effectiveness are discussed, including ability to reach areas of severe need, promotion of local involvement, low cost of operations, adaptiveness and innovation, independence, and sustainability. A summary is provided of major future challenges in international health that may be addressed by NGOs, with particular emphasis on tobacco-related disease, communicable diseases and the AIDS epidemic, maternal mortality and women's health, injury prevention and control, and the need to secure durable financial support.

Human immunodeficiency infection and AIDS are a major recent microbial infection in east Africa with serious health and socioeconomic impacts in the region. At present HIV infection and AIDS account for more than 50% of adult medical admissions into some of the national and provincial hospitals as well as for 10-15% of paediatric admissions. AIDS is also at present the commonest cause of death among those aged 15-45 years. ⋯ While a lot of scientific advances have been made in immunopathology of AIDS, diagnostics and in social behavioural studies, we are still a long way towards getting curative therapy and or effective preventive vaccines. Recent discovery that use of zidovudine can significantly reduce perinatal HIV transmission is an additional breakthrough. While knowledge and tools for preventing HIV transmission are available in the world, prospects for AIDS control in east Africa appear gloomy unless major efforts are made in the reduction of poverty, ignorance and in the control of other common sexually transmitted diseases.

ReviewPerformance and potency of tetanus toxoid: implications for eliminating neonatal tetanus.
Neonatal tetanus (NT) is a major cause of mortality in developing countries, with over 400,000 deaths estimated to occur annually. WHO has adopted the goal of eliminating NT worldwide, and a major strategy for its prevention is the administration of at least two properly spaced doses of tetanus toxoid (TT) to women of childbearing age in high-risk areas to protect passively their newborns at birth. In certain countries the locally produced TT vaccine has been shown to be subpotent, while other countries have reported NT among infants born to vaccinated women. ⋯ Of these, 15 lots from eight manufacturers in seven countries had potency values below WHO requirements. TT potency can also be compromised by improper vaccine handling. To eliminate neonatal tetanus worldwide requires assurance that all doses of TT meet WHO production and quality requirements and that the field effectiveness of TT is monitored through systematic NT case investigations and assessment of coverage.
