Medical reports modelled after the US Peace Corps surveillance form provided mortality and morbidity data of the United Nations Transition Assistance Group in Namibia in 1989-1990. Contingents included Australians, Canadians, Danes, Finns, Kenyans, Malays, Poles, Spaniards, and Britons. Traffic accidents, mostly those on long distance journeys caused 14 of 16 deaths. The fatality ratio was 0.21/million km driven which was considerably higher than that in Switzerland 0.02/million km driven. Even though heavy traffic was not a problem in Namibia, limited experience on unpaved roads; high speeds induced by long and tedious driving; and reduced visibility caused by climactic conditions, fatigue, and alcohol contributed to high fatality. The hospitalization rate of 5.2% (369 patients) was rather high for a young and healthy population. The leading reasons for hospitalization included fever of unknown origin, trauma, and respiratory tract infections. Swiss Medical Unit physicians transferred 25 patients to the State Hospital in Windhoek, most for orthopedic surgery. Injuries, psychiatric problems, and alcoholism resulted in repatriation for 66% of 46 repatriated patients. New consultations for treatment averaged 2.7/person and those for preventive measures averaged 0.8/person. Helicopter pilots was the largest group returning for 2nd visits (56% compared to 1% for logistics staff). The major reasons for attending outpatient clinics included immunizations (18.8%), dental problems (10.5%), and respiratory infections (10.5%). In addition to respiratory infections, other frequent communicable diseases included diarrhea or dysentery, dermatological infections, sexually transmitted diseases, and confirmed or suspected malaria. Preventive measures are needed to reduce mortality due to traffic accidents and the prevalence of psychological and dental problems.

The atoll community of Fenuafala was surveyed during July-August, 1987. A disproportionate demographic structure was found: There was a large, young population with an uneven sex distribution in the adolescent cohorts. Adoption of relatives was frequent. Employment varied according to sex, with women restricted from horticulture, fisheries, and hard labour. The use of alcohol and tobacco was common. Causes of mortality included cancer, heart failure, meningitis, alcoholism, and accidents. Bacterial and fungal skin infections were prevalent. There were several cases of congenital disorders. Malaria, leprosy, and most other tropical diseases were absent. However, there was a single case of filariasis. Musculoskeletal disorders were numerous and more common among women. Falls from trees have resulted in serious sequelae including epilepsy and death. Hypertension, diabetes, and gout appear to be on the increase, but angina and myocardial infarction were not reported. There were also cases of epilepsy and Parkinson's disease.

In a Nigerian town with a stable population of 20,000, a door-to-door survey was conducted, using a questionnaire involving a complete census and a simple neurological evaluation which had previously showed a 95% sensitivity and an 80% specificity for detecting neurological disease. Positive responders were evaluated and categorised, using agreed criteria for diagnoses. Nearly 100% cooperation was obtained. Life prevalence ratio for at least one episode of headache was 51/1000. Crude point prevalence ratio for migrainous headache was 5.3/100, and peak age-specific ratio was in the first decade. Prevalence ratio for epilepsy was 533/100,000 and peak age-specific prevalence ratio occurred in the 5-14 years age groups. The prevalence ratio for peripheral nerve disorders was 268/100,000, and age-specific prevalence ratio for tropical neuropathy increased with age. Prevalence ratio for stroke was rather low at 58/100,000, but was probably due to the people's attitude to the disabled elderly and high mortality of stroke which showed annual mortality rate of 70/100,000 which increased with age to 1519/100,000 per year in the eighth decade. Crude prevalence ratios (cases per 100,000) for others are 112 for neurological complications (including sciatica) of spondylosis, 15 each for poliomyelitis, motor neurone disease, development speech disorders, 10 each for syncope, hereditary neuropathies. Parkinson's disease, benign essential tremor, primary cerebellar degeneration, cerebral palsy, mental retardation, organic psychosis (probable intracranial tumor) and 5 each for muscular dystrophy, pyomyositis, spina bifida occulta, alcohol dependence and cerebral malaria. The implications of the findings are important for development of community neurological services in the developing countries.

A case of tropical splenomegaly syndrome in a 66-year-old white man who had lived in Tanzania for 34 years is described. He had taken anti-malarial prophylaxis continuously and regularly. He had had malaria in 1955 but there was no history of alcoholism or jaundice. He was treated with proguanil hydrochloride and, after return to Tanzania, took paludrine as prophylactic. One year later he had no further complaints, the spleen was no longer palpable and the liver only just palpable.

Clinical analysis of 293 cases of cirrhosis from two moderate sized hospitals in the city of Dacca has been presented. Maximum number of cases were in the age group over 40 with 150 (51.2%) males and 19 (5.8%) females. Significant past history included viral hepatitis (21.5%), kala-azar (11.6%) and malaria (10.24%). History of alcoholism was present only in 16 (5.5%) cases. Weakness (84.3%), weight loss (72%) and anorexia (39.3%) constituted the most common symptoms. Ascites (45%), haematemesis (11.6%) and melaena (28.7%) were the next common symptoms. Hepatosplenomegaly was found in about one-third of the cases. Testicular atrophy was recorded in 41.63% cases whereas gynaecomastia was relatively less common (5.5%). Scanty body hair and white nails were present in almost equal number of cases (14.7% and 18%). The cases presented here are those with overt manifestation. Nevertheless, the clinical features are not materially different from those reported by other authors. In the absence of alcoholism, viral hepatitis is presumably the most important aetiological factor in our cases and the clinical features compare favourably with non-alcoholic cirrhosis of the western writers. Cryptogenic cirrhosis has been considered to be most common type constituting 43.7% of our cases.

Neurologic manifestations of severe infectious complications of drug abuse and chronic alcoholism are reviewed in this article. Portals of entry from cutaneous postinjection infections and multiple vascular injection sites may lead to pyomyositis, tetanus, infective endocarditis, meningitis, brain abscesses, and vertebral osteomyelitis. Chronic intranasal abuse of cocaine may be followed by frontal osteomyelitis, botulism, brain abscess, and visual loss. Problems of hepatitis, malaria, and syphilis in drug abusers are discussed also.

The study investigated beliefs of 121 high school students in Grade 11 about people who are ill with malaria, tuberculosis, HIV/AIDS, and alcoholism. The sample of Black pupils were chosen at random from two rural secondary schools in one region in the Northern Province of South Africa. Analysis indicated that HIV/AIDS was clearly distinguished from the other three illnesses by being seen as the least easily cured, having the most gradual onset, being the most contagious, showing the least look of illness, and the patients being likely those most blamed for their illness.

There is increasing concern about the potential neurotoxic effects of exposure to methylmercury for the 6 million people living in the Amazon, even in regions situated far away from the gold mines (garimpos), considered to be the major source of mercury pollution. In November 1998, a spot investigation on mercury contamination was conducted in three fishing villages (Barreiras, Rainha, and Sao Luiz do Tapajos) on the Tapajos River, an effluent of the Amazon, situated several hundred kilometers downstream from the gold-mining areas. A total of 132 fishermen and their families volunteered for the current study. As was anticipated, the total mercury levels in the head hair collected from the fishing villages were relatively high (14.1-20.8 ppm on the average) and the number of subjects with a high total mercury level over 10 ppm (the least upper bound of a normal value) was 103 (78.0%) in total, along with various symptoms, thereby suggesting wide mercury contamination in the Tapajos River basin. Moreover, in view of the absence of other diseases (e.g., alcoholism or malaria), a high intake of fish containing a methylmercury level, and high hair mercury levels in addition to the various symptoms such as sensory disturbance (especially glove-and-stocking type, which is characteristic of Minamata disease), tremor, failure in two-point discrimination, and slight balancing failure, several subjects examined were diagnosed with mild Minamata disease. The findings obtained suggest, thus, that the mercury pollution in the Amazon should be crucially observed for head hair mercury level and health in a much broader region.

Global aging superimposed on existing infectious diseases and trauma will aggravate competition for health care resources to diagnose and treat osteoporosis. Efforts to implement public health measures are needed, but the targeted approach to assessment and treatment of high-risk individuals must also be refined. Increases in the elderly population worldwide will cause a dramatic rise in osteoporotic fractures, but other age-related diseases will increase as well. Changes will be superimposed on existing public health problems (e.g., malaria, alcoholism), and these acute health care needs will take priority in some areas. Societies in most parts of the world may have to limit osteoporosis control to broad public health measures, and such efforts (e.g., calcium and vitamin D supplementation) should be supported. In these regions, clinical decision-making will generally be limited to treating patients with fractures (who presumably have already failed any public health measures in place), or in a few wealthy countries, to patients with low bone density identified by case-finding. Case-finding approaches will vary with the resources available, although unselective (mass) screening by bone densitometry is largely ineffective and unaffordable anywhere. The key to clinical decision-making on behalf of individuals will be an assessment of absolute fracture risk, and the tools needed to predict the risk of an osteoporotic fracture over the next 10 years are now being developed. These include bone density measures, but also incorporate other risk factors (e.g., fracture history, corticosteroid use), which may allow extension of fracture risk prediction to nonwhite populations and to men. Even with a universal risk prediction tool, cost-effective treatment thresholds will vary by country based on the level of fracture risk in the region and on the resources available for health care. To better compete for these resources, efforts should be made to lower the cost of osteoporosis interventions. Additionally, evidence is needed that these interventions are really effective in reducing fractures in the community.

Central pontine myelinolysis (CPM) is a clinical condition characterized by myelin destruction in the rostral part of the pons. It is commonly found in association with alcoholism, rapidly corrected hyponatraemia and electrolyte abnormalities. We describe here an unusual case of CPM occurring in a patient with cerebral malaria.
