A comparison of pregnancy course and outcome between 648 Hmong refugee women and 5278 non-Hmong controls, all of whom delivered at a Minnesota medical center in 1976-83, indicated that Hmong women were 5 times as likely to have a history of previous perinatal loss. In terms of demographic factors, Hmong women were more likely to be age 35 years or above at delivery (14% versus 2% among controls), to be grant multiparas (33% versus 3% among controls), and to be married (95% versus 61% among controls). While 59% of controls began prenatal care during the 1st trimester, only 16% of Hmong women fell into this category and 31% delayed receiving care until the 3rd trimester. A review of the obstetric histories revealed that 18.1% of Hmong women compared with 3.7% of controls had experienced 1 or more previous perinatal loss. Medical conditions found with significant frequency in the Hmong population included anemia, tuberculosis, malaria, and parasitic infestations. Preeclampsia, hypertension, diabetes, urinary and vaginal infections, and gonorrhea occurred less frequently among Hmong women than among controls. Moreover, the incidence of premature rupture of the membranes was only 4.2% among Hmong women compared to 11.8% among controls. The prematurity rate was 48.5/1000 in the study group and 117/1000 in controls; in addition, only 7.8% of Hmong infants compared to 10.9% of control infants were low birthweight (under 2500 grams). The perinatal mortality rate was similar in both groups: 14.6/1000 among Hmong infants and 15.0/1000 among controls. Contraception was accepted by 50% of the Hmong mothers, but under 10% remained users 12 months after delivery and 27% were pregnant again. The generally good pregnancy outcomes recorded among these Hmong women despite the existence of numerous high-risk factors--short stature, advanced maternal age, grand multiparity, late prenatal care, and poor nutrition--is surprising. It appears that relocation to the US has enabled this population to overcome the factors that contributed to their previous high rates of perinatal loss.

Although several attempts have been made in the developed countries to study the effect of various environmental factors on morbidity, it is disappointing that in developing countries where very poor conditions exist, very little information is available on the subject. This study was therefore designed to examine the influence of the living and working environment on the state of health of two groups of Nigerian workers namely farmers and industrial workers. The study was carried out in two villages Badeku and Ewekoro. 200 farmers from Badeku and 150 industrial workers from Ewekoro were selected by appropriate sampling methods. Most of the data were obtained by means of a questionnaire administered by the authors. In addition to a detailed clinical examination of each subject, blood stool and urine specimens were obtained for laboratory investigations. A high incidence of hookworm and ascaris infection, anaemia, leg ulcer, malaria parasitaemia and onchodermatitis was found among the farmers. The industrial workers on the other hand had a higher incidence of chronic bronchitis and hypertension. Some of these findings have been attributed to poor environmental hygiene of the homes and work places, atmospheric pollution and other health hazards associated with living and working in the rural areas.

Quartan malaria developed following splenectomy 36 years after infection in a 63-year-old hypertensive man. The patient underwent nephrectomy because of left renal calculus, increasing proteinuria and hypertension. Splenectomy was done additionally because metastasis of renal tumor to the spleen was suspected at the operation. Attention is drawn to the long silent infection with Plasmodium malariae and to the importance of the spleen in malaria.

Between 1975 and 1983 health care expenditures in Ghana dropped to a low point as a consequence of the structural readjustment program instituted by the World Bank. During 1975-76 only 15% of available funds were spent on primary health care (PHC), which was officially introduced in the late 1970s. PHC made up 20-25% of the health care expenditures by 1991 with about 25% of health personnel engaged in PHC. 2/3 of health care delivery covered urban areas when 60% of the population lived in the countryside. The district of Ejisu-Juaben in the Ashanti region had high morbidity. Tetanus, polio, whooping-cough, and diphtheria had been brought under control, but measles, diarrhea, and malnutrition were still widespread among children under 5 years old. Malaria, bilharzia, intestinal parasites, respiratory infections, hepatitis, anemia, hypertension, and vitamin A deficiency were also grave problems. AIDS was on the rise. Child mortality amounted to 130/1000 live births and maternal mortality to 1400/100,000 cases. The medical structure of the district comprises 10 health posts (6 governmental and 4 mission). Only 72 villages and 120,000 people are cared for. Each post has a mobile team. In 1993 a new community-based health care program began funded by Save the Children Netherlands. In 60 villages a village health committee existed but they were substandard. They were either reactivated or new committees were set up. Training activities were also started in prenatal care, delivery, care of malnutrition and diarrhea, hygiene, and sanitation. Two years later safe motherhood indicators had improved; postnatal care increased from 16% to 49%; medical deliveries increased from 27% to 37%; the share of families with contraceptive acceptance increased from 7% to 21%; and tetanus vaccination among mothers was estimated to have increased from 27% to 86%.

This article reports on an examination of maternal mortality in Guinea-Bissau during 1989-90. Verbal autopsies were conducted and matched to hospital and health center records. The 145 maternal deaths identified in this study were matched to controls. The estimated maternal mortality ratio (MMR) was 914/100,000 live births. The MMR for hospitals was 779/100,000. Few women with infections or hemorrhage received proper medical attention. Cases of obstructed labor usually involved malpresentation of the fetus and cephalopelvic disproportion. The main indirect causes of maternal mortality were anemia and malaria. Almost 70% of deaths were to women younger than 30. 32% of deaths to women younger than 20, 9% of deaths to women 20-29 years old, and 22% of deaths to women 30-39 years old were due to eclampsia. 27% of deaths among 30-39 year old women and 33% of deaths among women 40-49 years old were due to postpartum hemorrhage. The comparison of prepregnancy symptoms among women who died and women who did not showed that death was related to female genital mutilation, specifically excision or infibulation. This practice is common among certain tribes, which also have a young marriage age and slight stature. The highest mortality was among women with no prenatal care (45 deaths). 41 women who died made a few prenatal visits. 33 deaths were to women who made over 3 visits. 71% of the 145 women who died had experienced some complications (anemia, malaria, generalized edema with or without hypertension). Only 20.4% of women who died and 30.2% of living women were temporarily admitted to the hospital for these symptoms during pregnancy. 43% of survivors of a similar condition to those women who died made prenatal visits during the first trimester. Twice as many controls delivered at home compared to the hospital; the reverse held for women who died. 40% of women who died and only 26% of the control group had deliveries attended by family or traditional birth attendants. 14% versus 40% in the control had midwives delivering births. 28% versus 19% of control reached the health facility in over 24 hours. 53.7% versus 86.9% of controls had live births.

The value of ethanomedical information in drug development is based on several factors: accuracy in recording or observing the medical use of the ethnomedical preparation, whether or not the ethnomedical use can be corroborated under scientific conditions in the laboratory, the formal or informal experience of the practitioner who provides the information, the role of the placebo effect and perhaps many others. Published ethnomedical information has many strengths and weaknesses relative to the ability to establish a corresponding biological effect in the laboratory. Many of the publications contain insufficient detail for the laboratory scientist. The ability to correlate ethnomedical reports with corresponding scientific studies could lead to improved selection of plants for further study in the areas of arthritis, cancer, diabetes, epilepsy, hypertension, malaria, pain and fungal and viral infections. These analyses have been accomplished by computer analysis utilizing the NAPRALERT database. This combination of analysing ethnomedical information and published scientific studies on plant extracts (ethnopharmacology) may reduce the number of plants that need to be screened for drug discovery attempts, resulting in a corresponding greater success rate than by random selection and mass bioscreening.

We studied residents of urban and rural areas of Ghana from 1972 through 1987 to evaluate the health burden of cardiovascular diseases, especially high blood pressure, in these African communities. Among urban adults, the prevalence of hypertension was 8% to 13%, compared to only 4.5% among rural adults. Overall, rates were higher among men than among women. However, the rate of hypertension was the same for men and women over 40 years old. The prevalence of hypertension was 29% for persons aged 35 and older, compared to 3.9% for persons under 35 years of age. Of the 24% of the study participants who were aware of their hypertension status, only a third were undergoing treatment, and only half of those were receiving adequate treatment. The determinants of hypertension include age, family history, body mass index, parity, and alcohol use. On a continent where over 80% of the health budget is spent on communicable diseases such as malaria, this study represents one of the few early attempts to understand the magnitude of the health burden of noncommunicable diseases in Africa.

Computed tomography was performed on 14 unconscious Kenyan children recovering from cerebral malaria (seven of whom had another scan 12-120 days later) to elucidate the cause of intracranial hypertension and neurological sequelae. Brain swelling, defined as a loss of cerebrospinal fluid spaces, was documented in six children, while a further two had conspicuously small ventricles only. There was severe intracranial hypertension in the two children with definite brain swelling in whom intracranial pressure was monitored. There was no evidence of acute hydrocephalus or vasogenic oedema. Four children with brain swelling also had widespread low density areas suggestive of ischaemic damage. The patterns of damage were not uniform but were consistent with a critical reduction in cerebral perfusion pressure (which was documented in the two in whom this was monitored), hypoglycaemia, or status epilepticus. All four had serious neurological sequelae. These data suggest that brain injury in cerebral malaria may be due in part to secondary systemic and intracranial factors as well as to the direct effect of intravascular sequestration.

In pre-colonial times, health in some Pacific countries was good compared with that of Europe. Illnesses such as scrofula, rheumatism, and filariasis often received herbal treatment. More recently, however, traditional diet throughout the region have been replaced by canned fish, biscuit, white flour products, and sugar-laden food. New illnesses and diseases have emerged in Pacific countries since European intrusion. Though malaria is still the primary cause of death in Vanuatu, diabetes, hypertension, obesity, and coronary heart disease are prime health concerns in most Pacific countries. In Kiribati, health educators use materials in discussion groups and schoolteachers use special materials on AIDS in their teaching, Calendars are produced in cooperation with national nutrition and family planning (FP) groups and agencies that highlight health topics such as AIDS and vitamin-A deficiency. Material produced by the Vanuatu health education unit features nutrition, the environment, FP, and AIDS and other sexually transmitted diseases. The government's Women's Affairs Department the International Labor Organization and other agencies are involved in FP and family life education. In Fiji and the Solomon Islands, nutrition has been highlighted in health education campaigns. In both countries surveys indicated alarming levels of diet-related disease. Another important nutrition project in the Solomon Islands is the village education program. At a training center, trainers conduct 15 practical courses for mobile workers, community workers, and village resource persons. Under this program, 60 village-level workshops are held each year focusing on nutrition, cooking, and gardening. Nutrition is now a major focus of health in the Pacific. The health, nutrition, education, fisheries, and agricultural sectors work with other agencies for success through community participation and through an integrated approach.

Considerable success is now being achieved in defining genetic susceptibility loci in polygenic disease. In particular, new susceptibility loci have been identified in hypertension, type I and type II diabetes, asthma and malaria infection. The approaches and tools for mapping such susceptibility determinants are becoming more clearly defined and the identification of further susceptibility genes is likely to be in demand in the near future.
