Pulmonary function studies in Nigerian sportsmen.

Lung function studies in Nigerian sportsmen were performed during the Western State Sports Festival. The sportsmen comprise 259 males and 151 females. They were made up of secondary school students, University undergraduates, young clerical and technical workers and soldiers. The forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) were performed using the wedge bellows vitalograph. The results of the investigation are presented. It was observed that the mean FVC and FEV1 values were lower than the predicted mean values of normal Nigerians when matched for age, sex, height and weight. However, the mean observed FVC value of athletes was higher than the observed FVC value of non-athletes. It was also noted that the mean FVC value of the sportsmen correlates with their sporting events, which are determined by the extent of regular and strenuous physical training.

Sex ratio of live births in south-western Nigeria.

Among European and North American whites, the proportion of males among live births is about 51.4%, while among negroes in the United States the figure is 50.7%. To test the correctness of the common assumption that the proportion among Africans is the same as that for negroes in the United States, records over seven years for Yorubas of south-western Nigeria have been examined. Among 548 558 hospital live births the male proportion was 51.37%, while vital registration records for one urban and one rural town showed a figure of 51.39% in 315 735 live births. Of the total 864 331 live births, the overall proportion was 51.4 +/- 0.05%, significantly higher than the 50.7% for American negroes.

Causes of mortality in an African city.

Registered deaths from the vital statistics registration system of Lagos City, a system that was judged to be 60% complete, were analysed for the year 1977. Nearly 40% of total registered deaths were from infections, parasitic diseases and motor vehicle accidents. Of the reported deaths, 17.3% were from ill-defined conditions. Deaths from neoplasms, diseases of the nervous and sense organs, diseases of the digestive and genitourinary systems as well as those from congenital anomalies are relatively less frequent. Maternal mortality appears to be very high. The age pattern of mortality is different from that in the developed countries, a high proportion of the deaths in Lagos City being those of children aged under 5 years. Infant mortality is dominated by perinatal causes which constituted a huge 38.4% of deaths of infants under 1 year, the other important causes being dysentery and diarrhoea, pneumonia and tetanus. Among adults, death from motor vehicles accidents is the most important cause accounting for more than 26% of deaths in the age group 15 years and above. Other important causes of adult deaths are cerebrovascular disease, hypertensive disease, heart disease, pneumonia, dysentery and diarrhoea and complications of pregnancy. Well organized health services stressing antenatal care, preventive and health education services are needed to effect a reduction in mortality and bring about a general improvement in the health of the people.

Gastric acid secretion using pentagastrin: dose-response studies.

The results of gastric stimulation using varying doses of pentagastrin in twenty-five Nigerians (twenty cases of duodenal ulcer and five controls) are presented. Doses used were 4, 6, 8, and 10 micrograms/kg bodyweight. The optimal response was obtained using 6 micrograms/kg bodyweight in the test cases while the maximum acid output (MAO) was 15.14 mEq/hr (19 mEq/hr in males, 12.50 mEq/hr in females). The recommended dose for optimal response in Caucasians is 6 micrograms/kg bodyweight which correlates with the dose in our patients. However, the maximum acid output at this dose is higher in Caucasians.
