Two Dutch researchers analyzed detailed standardized annual reports from 17 mission hospitals in Ghana, Kenya, Tanzania, and Zambia to determine what can be learned from hospital records on the volume of medical services provided as well as on the incidence and seriousness of major diseases and their patterns of change during 1975-90. These hospitals had more than 1.2 million patients (excluding deliveries, neonates, and premature births) and 67,534 deaths. The number of hospital admissions increased considerably (50-77%) in all countries except Ghana. Yet admission rates (per 1000 population/year) rose at a much lower rate (6-25%) in the three countries, suggesting that population growth accounted for a large part of the increase. During 1975-90, in Ghana, the admission rates decreased by 42% and the number of infectious disease admissions fell by 12%. More than 50% of all admissions were for infectious diseases in Kenya and Tanzania compared to 33% for Zambia and 35% for Ghana. Children aged under 15 years were more likely to be admitted for an infection or infection-related disease than adults (75% vs. 31%). The most common infectious disease responsible for admissions and a cause of death was malaria, probably due to a slowly rising resistance in the malaria parasite, resistance to insecticides in the mosquito, and the decreased immunity of the population due to uncontrolled use of antimalarials. In three countries (except Zambia for admissions and Ghana for causes of death), malaria has risen considerably (p 0.001). The case fatality rate for meningitis had also increased significantly during 1975-90 (p 0.001). Other significant causes of admissions and deaths included pneumonia, gastroenteritis, and tuberculosis. In all four countries, immunizable diseases and measles have declined greatly (p 0.001). Case fatality rates (CFRs) were highest for tetanus (36.7-68.8%) and meningitis (14.7-43%) and lowest for malaria (0.6-4.6%). CFRs for malaria, gastroenteritis, and pneumonia were much higher in adults than in children. These type of data are needed for planning and the operation of curative and preventive care.

Cryptic/sporadic malaria is rare in the United States. We describe a patient who developed malaria in New York City without any known contact with, or travel to, a malaria-endemic area. The patient presented with symptoms of gastroenteritis. Later, she developed hemolysis and hepatosplenomegaly, and Plasmodium falciparum was found in blood smears. Possible sources of malaria could be an indigenous infected mosquito or a transported infected mosquito from a local international airport.

Over an 18-month period, from October 1991 through early 1993, a study was carried out in two phases in the pediatric wards of the Eldoret District Hospital to document infant and child morbidity and mortality in the Uasin Gishu district and parts of several surrounding districts in western Kenya. Patient discharge summaries and ward registers were analyzed for age, sex, diagnosis, length of hospitalization, and outcome. There were a total 4720 pediatric admissions over the period. The most frequent 20 diseases were identified and their respective case fatalities were calculated. 74.5% of the admissions were due to only four diseases: malaria (33.0%), pneumonia (26.8%), gastroenteritis (10%), and measles (7.6%). Malaria was responsible for only 9 (9.1%) of all deaths. The disease specific mortality rate for malaria was 2.2%, 11th among the top 15 diseases. 20 (20.4%) out of a total of 98 deaths were due to pneumonia. Measles was becoming less important as a cause of morbidity because of immunization: in 1991, over 20 cases/per month were admitted, but by 1993 only 6.5 cases/month were admitted, a decrease of 68%. Neonatal tetanus was responsible for 43.2% of neonatal mortality during the 18 months. In addition, 47 infants and children had severe anemia (hemoglobin 4.0 gm%); 8 (17%) of these children died despite emergency blood transfusions. The overall mortality rate in the hospital during the study was 8.2%, which compares with 9.6% reported in Tanzania in 1987. 61 (64.9%) deaths occurred within 24 hours of hospitalization owing to delay in seeking medical care. In a 1988 study in Harare, 201 (43.7%) of 460 deaths occurred within the first 24 hours of admission. Furthermore, during February through June 1992, 29 of 57 children under 2 years of age admitted for gastroenteritis tested positive for HIV antibodies. A retrospective review of the ward register also showed that in 20% of the admissions the outcome was not recorded, in 25% the length of stay could not be determined, and for 8.3% the age of the patient was not recorded.

All children 2 years and younger with diagnosis of gastroenteritis (diarrhea and vomiting) admitted to the Eldoret District Hospital between the February and June 1992 were enrolled. ELISA test was performed for HIV for each of the 57 children. In addition, relevant tests were carried out in all cases, such as hemogram, stool for ova and cysts, blood slide for malaria parasites, and urinalysis. The ELISA results were confirmed by the Western blot for all positive cases. A total of 57 children, 32 (56.1%) males and 25 (43.9%) females were studied. All the children were 2 years or younger, with 61.4% under 9 months old. The difference with respect to distribution of HIV positivity and negativity in those under 9 months and those above 9 months was significant (p 0.001). 29 of the 57 infants (50.9%) were ELISA and Western blot positive. Of the positive cases, 23 (79.3%) were 9 months or younger, with 6 (20.7%) between 9 months and 24 months (p 0.001). Of the 33 (58.3%) patients with diarrhea of less than 14 days' duration, 12 (36.70%) were seropositive, and of the 24 (41.7%) with diarrhea of more than 14 days, 17 (70.8%) were HIV positive. The difference in the duration of diarrhea in both the positive and negative cases in the 2 groups was significant. There were 34 patients who presented with diarrhea and vomiting alone of whom 15 (44.1%) were positive for HIV, while there were 10 who presented with diarrhea and either malnutrition or pneumonia with 8 (80%) positive for HIV. Diarrhea lasting more than 14 days was a significant parameter, as 70.8% of the patients in this category were seropositive for HIV compared to 36.7% in those with diarrhea of less than 14 days' duration (p 0.02). In addition, children 0-9 months old had a higher incidence of HIV seropositivity than the older age group, especially the age group 5-9 months, 73.6% of whom were seropositive.

Although most studies on the effect of vitamin A supplementation have reported reductions in childhood mortality, the effects on morbidity are less clear. We have carried out two double-blind, randomised, placebo-controlled trials of vitamin A supplementation in adjacent populations in northern Ghana to assess the impact on childhood morbidity and mortality. The Survival Study included 21,906 children aged 6-90 months in 185 geographical clusters, who were followed for up to 26 months. The Health Study included 1455 children aged 6-59 months, who were monitored weekly for a year. Children were randomly assigned either 200,000 IU retinol equivalent (100,000 IU under 12 months) or placebo every 4 months; randomisation was by individual in the Health Study and by cluster in the Survival Study. There were no significant differences in the Health Study between the vitamin A and placebo groups in the prevalence of diarrhoea or acute respiratory infections; of the symptoms and conditions specifically asked about, only vomiting and anorexia were significantly less frequent in the supplemented children. Vitamin-A-supplemented children had significantly fewer attendances at clinics (rate ratio 0.88 [95% CI 0.81-0.95], p = 0.001), hospital admissions (0.62 [0.42-0.93], p = 0.02), and deaths (0.81 [0.68-0.98], p = 0.03) than children who received placebo. The extent of the effect on morbidity and mortality did not vary significantly with age or sex. However, the mortality rate due to acute gastroenteritis was lower in vitamin-A-supplemented than in placebo clusters (0.66 [0.47-0.92], p = 0.02); mortality rates for all other causes except acute lower respiratory infections and malaria were also lower in vitamin A clusters, but not significantly so. Improving the vitamin A intake of young children in populations where xerophthalmia exists, even at relatively low prevalence, should be a high priority for health and agricultural services in Africa and elsewhere.

The study aim was to evaluate the impact of mortality and primary health care (PHC) services utilization prior to death, based on data from the mortality surveillance system in the Upper River Division (URD) of The Gambia. The sample of villages with greater than 400 persons included 355 villages with a voluntary village health workers (VHW) and/or a trained traditional birth attendant (TBA), and 9 villages without. Recording of births and deaths was accomplished by one registrar for every 200 children or under, and totaled 373 village registrars and 8 field workers covering a population of 133,000. Cause of death for children aged 5 years was determined by 3 physicians and collected for senior field assistants. Morbidity data for children was gathered from monthly forms completed by VHWs and BAs. VHWs and TBAs were trained 6=8 weeks at Basse Hospital and 4-6 weeks at Bansang Regional Hospital, respectively, with periodic retraining. Local PHC centers provided health education, environmental health education, immunization, nutrition, treatment and referral. There were 6 health centers in URD, which was the base of operations for travel to 5-6 sites 1-2 times per month for running clinics, evaluation of referred patients, and supervision of PHC activities. There were 16, 216 episodes of malaria, 6111 episodes of respiratory infection (ALRI), and 6380 episodes of acute gastroenteritis reported through the PHC system. That means .63, .23, and .25 episodes per person per year, respectively. More than 50% of cases of ALRI involved consultation with VHWs. There were 915 deaths among children aged 5 years in one year. Of the 94% reports on the deaths made by relatives, there were 85% dying at home, and 8% dying at a health center or hospitals. 13% (117) were inpatients during a portion of the precipitating illness. Survivors of illnesses were higher among those children receiving consultation with the VHW. Only 33% of children who died had consulted a VHW during the final illness. TBAs reported 50% of deaths recorded by the surveillance system. TBAs are selectively consulted.

Infections are the leading cause of childhood morbidity and mortality in developing countries. Bronchopneumonia, meningitis and gastroenteritis are the commonest fatal infections encountered in Ibadan. Tuberculous lymphadenitis, bronchopneumonia and meningitis are other frequent causes of death. The predominant sequela of measles is respiratory tract infection. Another important cause of childhood mortality is cerebral malaria. In half of the cases of tetanus no obvious portal of entry can be found. It is advocated that the implementation of immunization schedules should be vigorously pursued to curtail childhood mortality resulting from infection.

Following the establishment of university departments of pediatrics after World War II, national pediatric associations were formed in several countries (in Korea in 1945 and in Nepal in 1981). In Papua New Guinea, the Papuan Medical College began in 1959, and a university department of pediatrics was established in 1974. The population of Papua New Guinea is growing at a rate of 2.3% a year, and less than 70% of women receive prenatal care. Only 40% of deliveries are done under medical supervision. Most of child health problems are associated with malnutrition, pneumonia, gastroenteritis, malaria, meningitis, and tuberculosis. Nonetheless, the infant mortality rate (IMR) dropped from 134/1000 in 1971 to 72/1000 in 1980, and to 60/1000 in 1991. In Nepal, improved child health is a national priority, because the IMR is 129/1000 live births, the under-five mortality rate is 200/1000 live births, life expectancy is 52 years, and adult literacy rates are 39% for males and 12% for females. Nurses receive graduate pediatric training, and there is a postgraduate Diploma in Child Health. In Thailand, supervision of births increased from 33.7% in 1980 to 64.8% in 1988; the IMR dropped from 54.8/1000 live births in 1980 to 42/1000 in 1988; and malnutrition in under-fives dropped from 35.6% in 1980 to 28.5% in 1988. However, 85% of children live in rural communities, and rapid urbanization has resulted in overcrowding, with infectious and parasitic diseases, and high maternal malnutrition. Industrialization profoundly affected child health indices. In Korea the IMR was only 12.5/1000 in 1987, life expectancy was 67 years for males and 75 years for females. In Japan, the IMR dropped from 124/1000 in 1930 to 5.2/1000 in 1986; and maternal mortality declined from 176/100,000 live births in 1950 to 10.8 in 1989. Life expectancy increased from 59.6 years for males and 63 years for females in 1950 to 75.5 years and 81.3 years in 1988, respectively. In Australia, children's hospitals mostly treat asthma, congenital anomalies, and leukemia. Pediatric postgraduate education programs had been developed by the 1980's in most countries. The 7th Asian Congress of Pediatrics was held in Perth, Australia, in May 1991, focusing on priorities of child health.

A surveillance system was used to detect births and deaths in children in a large, rural, West African population from 1989 to 1993. Cause of death was investigated using post-mortem questionnaires. Overall infant (age 0-11 months) and child (age 1-4 years) mortality rates of 80.1 and 18.8 per 1000 per year were recorded. These were reasonably consistent over the period of surveillance. The most frequent cause of death in infants was acute respiratory infection (ARI), whereas in children it was malaria: these two conditions accounted for 41% of the deaths in children under 5 years old. Other leading causes of death were acute gastroenteritis, malnutrition, and septicaemia. Deaths attributed to ARI decreased over the 5-year period, but mortality rates from other causes were either unchanged or increased slightly. Mortality from all causes peaked in the rainy season and was slightly higher in villages which were part of a primary health care programme than in those which were not. There were also no differences between male and female mortality rates beyond one year of age. Despite the introduction of a number of health interventions, there has been no major change in the overall pattern of mortality in children in a rural area of The Gambia. Malaria and ARI remain the main causes of death.

A prospective case-control study conducted on the north coast of Papua New Guinea in 1993-96 investigated the hypothesis that alpha(+)-thalassemia provides a selective advantage against endemic Plasmodium falciparum. In this geographic area, alpha(+)-thalassemia affects more than 90% of the population. 249 children admitted to Madang Hospital with one or more symptoms of severe malaria (severe anemia, coma, hypoglycemia, acidosis, and hyperlactatemia) were paired with 249 randomly selected healthy age- and sex-matched controls. Also enrolled were 233 children with infections other than malaria, primarily respiratory infections, gastroenteritis, and meningitis. Compared with healthy community controls, the risk of severe malaria was 0.40 (95% confidence interval (CI), 0.22-0.74) in alpha(+)-thalassemia homozygotes and 0.66 (95% CI, 0.37-1.20) in heterozygotes. The lowest odds ratios for alpha(+)-thalassemia homozygotes were recorded in the acidosis and hyperlactatemia subgroups--the two complications most predictive of malaria mortality. Unexpectedly, the risk of hospital admission with infections other than malaria was reduced to a similar degree in homozygous (0.36; 95% CI, 0.22-0.60) and heterozygous (0.63; 95% CI, 0.38-1.07) children. Although the relevant mechanism is unknown, these findings confirm a clear interaction between thalassemia hemoglobinopathy and both malarial and other infections. Given its high frequency and protective effect against malaria and some other infections, alpha(+)-thalassemia is likely to have a major impact on child survival in coastal Papua New Guinea.
