The literature on health implications and effects of government-sponsored resettlement in Ethiopia is reviewed with the objective of providing an initial evaluation of the health status of settlers and the health hazards of resettlement in western Ethiopia. Emphasis is on the 1984/85 resettlement program, which resulted in the movement of about 600,000 drought victims from northern and central Ethiopia to the western part of the country. Malaria, trypanosomiasis, onchocerciasis, yellow fever, nonfilarial elephantiasis, sand-flea infestation, and psychological stress are identified as immediate and greater health hazards than in the areas of settler origin, based on the geographic distribution and ecology of the major communicable, nutritional, and geochemical diseases in Ethiopia, and on the impact of program deficiencies on settler health. More studies are needed on the epidemiology and ecology of bancroftian filariasis, visceral leishmaniasis, dracunculiasis, eye and skin diseases, tuberculosis, meningitis, intestinal parasitism, diarrhea, and calorie/protein malnutrition before their public health and economic significance in settlements can be evaluated. Schistosomiasis appears to be less common, for the time being, in resettlement areas than in the areas of outmigration. Research needs and constraints in resettlement planning, implementation, and operation are identified, and some recommendations made for disease control programs.

A retrospective survey was carried out on adult medical admissions to Kamuzu Central Hospital, Lilongwe, Malawi during the period January to December 1986, and results compared with those obtained in Queen Elizabeth Central Hospital, Blantyre in 1973. There were 4700 admissions which was more than twice the number seen in Blantyre. However, the age distribution, the pattern of disease and the overall hospital mortality were similar. Infections (malaria, pneumonia, tuberculosis, gastroenteritis/dysentery and meningitis) were the most common cause of admission, and the major causes of death were still tuberculosis, pneumonia and meningitis. Smoking related diseases were uncommon, and there was no documented case of ischaemic heart disease. The reasons for the importance of periodic surveys, such as the present study, are discussed.

We have studied prospectively the C-reactive protein values in the cerebrospinal fluid of 54 patients with bacterial meningitis, tuberculous meningitis, and severe malarial infection and convulsions without infections of the central nervous system. CSF CRP above 1 mg/l was observed in 23 out of 28 patients with bacterial meningitis (sensitivity of 82%). The specificity was 73% at the 1 mg/l level. Five out of 19 patients with severe malarial infection had CSF CRP levels above 1 mg/l. Two patients with TB meningitis were also studied. Both of them had CSF CRP above 1 mg/l. Five patients with febrile convulsions or sepsis without meningitis had CSF CRP below 1 mg/l. It is concluded that CSF CRP would not be used as a useful discriminatory test in areas where malaria and TB meningitis are common.

A prospective study using a Latex particle agglutination test for the detection of bacterial antigens in CSF has been carried out in 91 patients in Kamuzu Central Hospital, Malawi. The antigens sought were those of Streptococcus pneumoniae, Haemophilus influenzae b, Neisseria meningitidis B/E. coli K1, and Neisseria meningitidis A,C,Y,W 135. Forty-one patients had proven bacterial meningitis, two had tuberculous meningitis, 39 had cerebral malaria, four had aseptic meningitis and five had convulsions. The sensitivity and specificity of the tests (Str. pneumoniae, 88% and 100%, H. influenzae b, 87% and 96%; N. meningitidis A,C,Y,W 135, 100% and 100%; and N. meningitidis B, 100% and 98%) were as good as those reported from developed countries. Unlike in some other parts of Africa, group B meningococci seem to predominate in cases of meningococcal meningitis in Malawi.

The registry of patients at the hospital of Kampene, Zaire, covering the period 1986-87 was examined to determine the hospital's rate of utilization and accessibility, to evaluate mortality, and to ascertain the prevalence of infectious diseases. The 1986 data of the hospital laboratory indicated a high incidence of infectious and parasitic diseases: ancylostomiasis (33.6%); ascariasis (22.9%); schistosomiasis (3.4%); multiple intestinal parasitic infections (10.9%); malaria (43%), often chloroquine-resistant; filariasis (70.8%); and alcohol-acid resistant tuberculosis bacilli (15%). Sexually-transmitted diseases such as vaginitis (80%) were caused by polygamy, prostitution, and promiscuity, HIV serodiagnosis could not be performed because of a lack of equipment. A high infant mortality rate was caused by neonatal tetanus, toxic gastroenteritis, measles (5.1% lethality: 2 died out of 39 cases), and epidemic cerebrospinal meningitis. Malnutrition caused kwashiorkor and avitaminosis. 792 births were registered at the maternity ward in 1986: 52.8% were male and 47.2% were female; 48 (6.1%) were stillborn or died in the following days; 104 (13.1%) were born prematurely; and 24 (3.1%) were twins. Cesarean section was performed in 43 cases (5.4%). There was a total of 15,099 outpatient visits during a 1-year period. The bed occupancy rate of the surgical ward ranged between .7 and .8 during 1987. Recovery and hospitalization days per doctor or health assistant were very high compared to Italian standards. The lethality of malaria was a high 1.8%, but malnutrition rated even higher: 21.4%. The utilization of the hospital was high, Maternal-child protection measures, especially in the area of nutrition, require the training of community health workers and traditional birth attendants; however, cost-benefit considerations limit resources and the implementation of primary health care is curtailed by economic and cultural factors.

In Germany, the last period of the Second World War and the following years were characterized by deficiencies of hygiene which had not occurred previously in Middle Europe during the 20th century. There were focuses of typhus, typhoid fever, tuberculosis, diphtheria, scarlet fever, and meningitis. Insufficiencies in the removal of faeces caused high incidences of shigellosis, hepatitis A, and ascariasis. As a result of insufficient body care, many people were infested with fleas, lice and scabies. The migration of large proportions of the population resulted in an increasing prevalence of syphilis an gonorrhea. As the population resettled, the first steps towards reorganization of public health could be done. The spread of typhoid fever was controlled by drinking-water disinfection with chlorine, repair of sewage systems, and patient isolation. The application of DDT helped to reduce scabies and pediculosis, resulting in decreasing typhus risks. During the first two decades after the war, there was a steady decrease of the incidence of infectious diseases. The reconstruction of the towns resulted in improved housing conditions and a decreasing number of persons per housing area, reducing the intensity of physical contacts of the inhabitants with each other. The nutrition and clothing situation of the population improved, which, in addition to a general rise of the standards of hygiene, brought about an increase of the individual resistance to infection. A further reduction of sporadic and epidemic outbreaks of infectious diseases was achieved by the introduction of chemotherapy and antibiotics. Increasing prosperity was accompanied by new problems of hygiene. Infectious diseases almost eradicated in West Germany, were imported by air travellers. Ten imported cases of smallpox were reported between 1957 and 1972, eight of which originated from Southeast Asia. Malaria, imported by German and foreign soldiers, had not been uncommon after the end of the war but had been easy to control by insecticides and antimalarials. As tourism expanded, a new wave of imported malaria cases was reported. In West Germany there is, however, no more spread of the disease under present conditions, cholera caused similar problems. The 1961 cholera epidemic started in Southeast Asia and caused minor outbreaks in Mediterranean countries like Italy and Spain. A significant spread of the disease throughout Europe was prevented by generally high standards of drinking water and sewage treatment. Sporadic cases of typhoid fever were imported from countries with low standards of hygiene.(ABSTRACT TRUNCATED AT 400 WORDS)

About 120,000 infants are born each year with sickle cell disease (SCD) in Africa. The majority have Hb SS, but Hb SC and Hb S/beta+ thalassaemia are common in west Africa. The development of Plasmodium falciparum and P. malariae is partially inhibited in the Hb SS red cells, but malaria precipitates both haemolytic and infarctive crises, and is the commonest and most important cause of morbidity and mortality. The pneumococcus is likely to be the second major infectious cause of sickness and death. In one rural community, there were less than 2% of the expected number of subjects with SCD surviving beyond 5 years of age. Genetic factors improving prognosis include (1) the Senegal beta chain haplotype, which is linked to a high level of Hb F, and (2) alpha+ thalassaemia. Of environmental factors improving prognosis, the family is of first importance. The commonest age of presentation is 1-3 years. Children present with anaemic crises (malaria, splenic sequestration, folate deficiency, and possibly aplastic), infarctive crises (hand-foot syndrome, bone-pain, pulmonary and abdominal) or acute infections (malaria, pneumonia, septicaemia, meningitis, osteomyelitis). Tragically, many patients in central Africa have been infected by the human immunodeficiency virus (HIV) through blood transfusions; they present with generalised lymphadenopathy and other features of the acquired immunodeficiency syndrome (AIDS). The principles of management are (1) to ensure freedom from malaria, (2) to continue folic acid supplements, (3) to give blood transfusions only when anaemia endangers life, (4) to control pain, (5) to restore hydration, and (6) to prescribe broad spectrum antibiotics in large dosage and without delay, but only when there are definite indications, such as fever (greater than 39 degrees C), acute pulmonary disease, meningitis, and acute osteomyelitis. The advent of HIV and AIDS makes the control of SCD of even greater importance. Principles of control are (1) early diagnosis through appropriate laboratory techniques and selective screening, (2) education of parents, patients, health professionals and public, and (3) the maintenance of health at sickle cell clinics; measures must include antimalarial prophylaxis. SCD programmes should be integrated with primary health care and AIDS control programmes.

The low-intensity war against Nicaragua from 1983 to 1987 has had a wide reaching impact on health, health services, and health economics in that country. Beyond the death of individuals and destruction of facilities, economic embargo and contra destruction have cost the health system about 200 billion cordobas between 1981 and 1987. This is approximately equal to the value of 2 years of the entire health budget. The war has resulted in decreased accessibility and availability of services, leaving about 10% of the population without access to modern health facilities. Perhaps 10% of the demand for acute care services is generated by the war, which has resulted in a reorganization of surgical and medical services. Long term care needs for psychiatric illness and rehabilitation services are far more extensive. Population movements and resettlement, where preventive care has been unavailable, are associated with epidemics of malaria, diarrheal diseases, measles, leishmaniasis, meningitis, and tuberculosis. Health services remain a high priority of the government as health care is viewed as a way to reduce the untoward effects of the war on the general population. Nonetheless, the indirect effects of the war have been detrimental to the system. Negative effect include the loss to the system of health professionals and rampant inflation. These forces contribute to the weakening of primary health programs and the reorientation of the national system into hospital based, curative medical services.

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.

150 patients admitted in medical coma at Muhimbili Medical Centre were studied prospectively to determine the causes and early prognosis. 89 (60%) patients had potentially treatable causes (60 cerebral malaria, 16 meningitis, 7 diabetic ketoacidosis and 6 drug over dosage). Other causes were 20 (13%) with cerebrovascular diseases, 30 (20%) hepatic failure and 11 (8%) were of miscellaneous and obscure causes. The cause of coma was an important indicator of prognosis. Good recovery was achieved in 42 (70%) with cerebral malaria, 4 (57%) diabetic ketoacidosis, 4 (25%) meningitis and 1 (16%) drug overdosage. Other indicators were the Glasgow Coma Score on admission and subsequent scores, early neurological signs and complications that arose. The Glasgow Coma Scale was found useful and easy to perform. Further studies are needed to confirm its usefulness in developing countries.
