The failure of up to half of all patients in developing countries to adhere to recommended drug regimens may reflect inadequate physician- provider communication rather than resistance to treatment. There is substantial evidence that patients are more likely to conform to treatment regimens when they are fully informed about their medical condition and the medication prescribed. To investigate the extent to which patients in Zimbabwe received this type of information, household heads in 910 households in the Mashonaland West Province were interviewed. The sample included equal numbers of respondents from urban, rural, and commercial farming areas. Diseases most commonly reported by rural residents and farmers were diarrhea, influenza, cough, hypertension, and malaria. Most of the illnesses were attributed to natural or supernatural causes, and 80% of respondents in these subsamples claimed to distrust their health care provider and never asked questions about medications prescribed. The rural residents perceived health care personnel as too busy to answer questions and did not believe they would understand any information offered. On the other hand, these respondents indicated they would like to have information on the cause of their illness, its duration and treatment, the best way to take prescribed drugs, actions to take when drugs produce side effects, and storage of medication. Physicians who treat semi-literate rural residents with indigenous health beliefs are urged to provide information about medication tailored to match the individual perceptions and needs of the patient. This need is less urgent in urban areas, where 60% of respondents had general knowledge about the action of various medicines and were able to obtain information from pharmacists.

The authors report the results of a study realized at National Hospital of Niamey (Republic of Niger) from october 1981 to may 1986. Among 4820 patients living in Western Niger, 410 (8.5%) had neurological disorders. Out of 16 recognized syndromes 6 constitute 75.2%: comas, paraplegias, cranial nerves palsies, convulsions, hemiplegias and sciaticas. An etiological diagnosis is made in 269 patients. From 15 diseases 4 totalize 73.5%: there are medullar compressions, infections of the central nervous system (bacterial meningitis, cerebral malaria), cerebral vascular disturbances and metabolic encephalopathies. POTT's disease is the most common cause of medullar compression with paraplegia and arterial hypertension is a very important etiologic factor of cerebral vascular attack (42.2 and 44.4% respectively). Parkinsonian syndrome and multiple sclerosis seem rare. The diagnosis of cerebral tumor is very uncommon but this is in relation to the absence of autopsy and of recent investigation (scanner). No case of tuberculous meningitis is noted and this can't be explained by the authors in a major tuberculous endemic area.

In order to identify the most appropriate interventions to reduce the amount of low birthweight among the Mendi people of Sierra Leone, the seasonal pattern of birthweights has been studied in three hospitals and compared with the incidence of known risk factors. Malaria and pregnancy-induced hypertension are shown to contribute to the excess low birthweight during the rainy season, particularly in primiparous women. There are no significant seasonal food shortages in this population and the best correlate for the bimodal seasonal excesses of low birthweight is the amount of agricultural work performed by the women during planting and harvesting. The significance of this for the choice of strategies to increase agricultural productivity is discussed.

A variety of tubular marker proteins, as compared to healthy controls, are excreted at an increased rate in the urine of patients with renal damage. Beside cytoplasmic glutathione-S-transferase and lysosomal beta-N-acetyl-glucosaminidase (beta-NAG) the majority of kidney-related urine proteins derives from membrane surface components of the most vulnerable proximal tubule epithelia, among them ala-(leu-gly)-aminopeptidase, gamma-glutamyl transpeptidase (GGT), the tubular portion of angiotensinase A, the major brush border glycoprotein 'SGP-240' and adenosine-deaminase-binding protein. Urinary tissue proteins, e.g. brush border (BB) microvilli, are immunologically identical with those antigens prepared from cell membranes of the human kidney itself. BB antigens are shed into the urine of patients with glomerulonephritis, interstitial nephritis, systemic diseases, e.g. systemic lupus erythematosus (SLE), diabetes mellitus and multiple myeloma, arterial hypertension, infectious diseases (malaria, AIDS) and after operations, renal grafting and administration of X-ray contrast media, aminoglycosides or certain cytostatics (cis-platinum). Tissue proteinuria of tubular proteins is determined by enzyme-kinetic or quantitative immunological assays applying either poly- or monoclonal antikidney antibodies. Clinical, ultrastructural and histochemical studies support the idea that both 'soluble' and high-molecular-weight membrane particles (vacuolar blebs, greater than 10(6) dalton) as well as microfilamental components of the epithelial cytoskeleton contribute to tubular 'histuria' which appears as a sensitive parameter in monitoring tubular damage under clinical conditions at a very early phase.

The mean annual rate of decline of the probability of dying 5 years of age in developing countries is 2.5%. Nevertheless disease accounts for a considerable proportion of premature deaths. The leading causes of death in these countries, in order, include respiratory disease, diseases of the circulatory system, low birth weight, diarrhea, measles, injuries, malnutrition, and neoplasms. These conditions represent diseases of poverty and affluence. Respiratory infections are common among 5-year old children and cause a high proportion of child deaths. Circulatory diseases tend to be limited to adults. Control of hypertension, diet, smoking prevention, and exercise can prevent circulatory diseases. The risk of dying in infancy and childhood and of developmental disabilities is higher among low birth weight infants than those who weigh 2500 gm. In Bangladesh, 50% of infants weight 2500 gm. Low birth weight is the underlying cause of death for many infants who die of respiratory infections and diarrhea. Oral rehydration can successfully treat most diarrhea cases. Malnutrition and diarrhea tend to occur together and feed off each other. In fact malnourished people are more susceptible to all infections. Malnourished children suffer from disabilities in development and growth. The greatest sufferers of measles are infants and malnourished children. Immunization of all =or 9-month old infants would eradicate measles. Children and young adults are at the highest risk of injuries. Lung cancer is on the rise in developing countries due to the increase of tobacco smoking. Various means of controlling malaria are use of mosquito nets, antimalarial drugs, reduction of mosquito breeding places, and pesticides. The new infectious disease, AIDS, has emerged as a considerable health problem in developing countries. High priority research areas are vaccines for Streptococcus pneumonia, Plasmodium app., rotavirus, Salmonella typhi (Ty21a), and Shigella spp.

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.

A case-control study was carried out to explore possible risk factors of primary hepatocellular carcinoma (PHC) in Taiwan. One hundred thirty-one PHC patients and 207 hospital control patients were interviewed and blood samples were collected for blood type and hepatitis B virus (HBV) infection marker tests. Eighty-three percent of the PHC patients were found to be hepatitis B surface antigen (HBsAg) positive as compared with 21.0% of the control patients with an odds ratio (OR) of 21.5. Hepatitis B e antigen (HBeAg) positive status increased the risk of PHC. No significant association was observed between erythrocyte genetic markers and PHC, except c of the Rh system, which was significantly lower in the PHC cases. As compared with the control patients, the PHC patients had a higher proportion with a history of liver diseases and more siblings affected with liver diseases. However, the variables such as cigarette smoking, alcohol drinking, peanut consumption, frequent intake of raw fish, heart diseases, peptic ulcer, malaria, hypertension, diabetes, color blindness, G-6-PD deficiency, surgical operation, blood transfusion, and liver diseases of parents and children were not found to be associated with PHC.

The government of Senegal, in March of 1986, requested assistance from the UN Development Program (UNDP) to formulate and execute a program for safe motherhood. Senegal, with an estimated maternal mortality rate of 580-760/100,000, was the 1st country to initiate a concrete national program to address the problem of maternal mortality. Despite the existence of a well-developed health infrastructure, data showed that the majority of Senegalese women deliver at home and that only 20% of maternal mortality is reported. Causes of mortality include endemic diseases (malaria and hepatitis), and abrupted placenta as a complication of hypertension. To identify the target areas of intervention, a "Mission of Identification" was organized by the UNDP in collaboration with the government of Senegal. 4 levels of the health infrastructure--village or rural maternity, the health post, the health center, and regional and national hospitals--were assessed as to existing and potential capacity to prevent maternal deaths. Epidemiology, social barriers to care, service delivery problems, and management issues were addressed. Results revealed a minimal knowledge of family planning, an expressed desire to solve the problems, and the strong influence of traditional beliefs in health care intervention, all of which contribute to maternal mortality. Interventions to reduce mortality were outlined based on identified causes of death and capabilities to address a specific problem. Over 50% of maternal deaths could be prevented by improved access and optimization of health care delivery and timely medical/surgical intervention. Adequate prenatal coverage and reducing pregnancy rates at the extremes of maternal age and parity were also cited as methods to reduce mortality. Estimates of the efficacy of these interventions were based on universal access, which does not now exist. A significant investment must be made to assure such access and to emphasize the priority given to maternal/child health by the government of Senegal.

Ethiopia is a country of 45 million people in northeast Africa. With a stagnant, agriculture-based economy and a per capita gross national product of $110 in 1984, it is one of the world's poorest nations. 70% of the children are mildly to severely malnourished, and 25.7% of children born alive die before the age of 5. Life expectancy is 41 years. The population is growing at the rate of 2.9%/year, but only 2% of the people use birth control. After the 1974 revolution, the socialist government nationalized land and created 20,000 peasant associations and kebeles (urban dwellers' associations), which are the units of local government. The government has set ambitious goals for development in all sectors, including health, but famine, near famine, forced resettlement programs, and civil war have prevented any real progress from being made. The government's approach to health care is based on an emphasis on primary health care and expansion of rural health services, but the Ministry of Health is allocated only 3.5% of the national budget. Ethiopia has 3 medical schools -- at Addis Ababa, Gondar, and the Jimma Institute of Health Sciences. Physicians are government employees but also engage in private practice. A major problem is that a large proportion of medical graduates emigrate. Ethiopia has 87 hospitals with 11,296 beds, which comes to 1 bed per 3734 people. There are 1949 health stations and 141 health centers, but many have no physician, and attrition among health workers is high due to lack of ministerial support. Health care is often dispensed legally or illegally by pharmacists. Overall, there is 1 physician for 57,876 people, but in the southwest and west central Ethiopia 1 physician serves between 200,000 and 300,000 people. In rural areas, where 90% of the population lives, 85% live at least 3 days by foot from a rural health unit. Immunization of 1-year olds against tuberculosis, diphtheria-pertussis-tetanus, poliomyelitis, and measles is 11, 6, 6, and 12% respectively. Infectious diseases dominate the medical scene in Ethiopia. In 1984, tuberculosis accounted for 11.2% of hospital admissions and 12.2% of deaths. The leading cause of childhood mortality in 1984 was diarrhea (45%). Malaria, trypanosomiasis, schistosomiasis, leishmaniasis, and meningococcal meningitis are endemic. Intestinal parasitism is rampant, and the nationwide prevalence of leprosy is 3/1000. Venereal diseases were the 9th most common cause of hospital outpatient visits in 1984, but AIDS is rare. The leading noninfectious diseases are rheumatic and syphilitic heart disease, hypertension, diabetes mellitus, hepatoma, and elephantiasis. Ethiopia has the highest number of cases of nonfilarial elephantiasis -- an estimated 350,000 cases -- in the world. Aside from a large influx of money, the most necessary changes to improve the health system are lowering the salaries of doctors and nurses, reorienting physician training toward primary health care, increasing the quality of existing health services, more efficient management, and better coordination between the Ministry of Health and the voluntary organizations.

Within a 2 month period 131 Ethiopian immigrants were admitted for treatment at a general hospital in Jerusalem. There were 52 patients with malaria, 13 with typhoid fever, 24 with pneumonia, seven with tuberculosis, nine with shigella and 11 with campylobacter. Over three-quarters of these patients were anaemic. In the majority of cases anaemia was normocytic and was most probably secondary to malaria and other intercurrent infections. The prevalence of diffuse non-toxic goitre was 7% in children and 19% in adults with a male to female ratio of 4:13. A positive rapid plasma reagin (RPR) test was found in 4% of sera tested and a positive HBsAg in 13%. IgG antibodies to HBc antigen were found in 75% of subjects. All patients with infectious diseases responded to therapy and, despite their poor condition at arrival, there were no fatalities and no late sequelae. The high HBsAg carrier state calls attention to the risk of vertical transmission by infected mothers and underlines the need for active immunization of infants at risk. The high prevalence of untreated tuberculosis and malaria poses a potential public health hazard, but with the current systematic screening of this population leading to identification and effective treatment of affected subjects, chances for the practical eradication of malaria and tuberculosis are excellent. Finally, the large scale transfer of a population from rural Africa to a modern and largely urban society presents a unique opportunity for a prospective study of the impact of environment on the emergence of diseases which plague modern society such as diabetes, atherosclerotic cardiovascular disease, hypertension and cancer.
