Some non-infective diseases endemic in the West Indies.

The West Indies, and associated parts of the Caribbean area, are extremely diverse and afford interesting examples for the study of geographical medicine. Short accounts are given of some conditions whose aetiologies have been relatively recently clarified, including vomiting sickness of Jamaica, veno-occlusive disease of Jamaica, blackfat pulmonary fibrosis of Guyana, and epidemic acute glomerulonephritis of Trinidad. The aetiology of tropical sprue, which is common in Puerto Rico and absent from Jamaica remains to be explained although a hypothesis has been put forward. Further work is needed to establish the geographical distribution of idiopathic cardiomegaly and the spinal neuropathies and associated syndromes of retrobulbar neuritis and sensorineural deafness before their aetiologies can be understood.

Studies of the relationship between Schistosoma and their intermediate hosts. III. The genus Biomphalaria and Schistosoma mansoni from Egypt, Kenya, Sudan, Uganda, West Indies (St. Lucia) and Zaire (two different strains: Katanga and Kinshasa).

The compatibility between strains of Schistosoma mansoni from Egypt, Kenya, Sudan, Uganda, the West Indies, and Zaire (two strains which came from Katanga and from Kinshasa), and various species and strains of Biomphalaria, i.e. Biomphalaria pfeifferi, B. alexandrina, B. glabrata and B. camerunensis was investigated. Data as mortality, rate of infection of the surviving snails, duration of infection, cercarial production per day per positive snail, etc., were observed. The main emphasis was placed on determining the total cercarial production per 100 exposed snails for each snail population. It was possible to infect all the tested populations of B pfeifferi with the various strains of S. mansoni, but the observation as e.g. TCP/100 exposed snails varied greatly according to the population of snail and the strain of S. mansoni. The results for the remaining species of Biomphalaria varied greatly, depending on the combination, e.g. B. alexandrina was only susceptible to the local S. mansoni from Egypt. The highest TCP/100 exposed snails was more than 1 million for the strains of S. mansoni from Egypt, Kenya and the West Indies in B. alexandrina, B. pfeifferi and B. glabrata, respectively. The next group, with a TCP/100 exposed snails on 7--800 000 consists of S. mansoni from Sudan, Uganda and Zaire (Katanga) all in B. pfeifferi. The last tested strain of S. mansoni, Zaire (Kinshasa) yielded a cercarial production on 500 000 per 100 exposed snails in B. pfeifferi and B. camerunensis. The shortest prepatent period, 19 days, was observed for S. mansoni from Kinshasa, Zaire, in B. camerunensis, and the longest prepatent period, 25 days, was found for strains from Egypt and from the West Indies in B. alexandrina and B. glabrata, respectively. In general, a very long duration of infection, lasting up to 200 days, was observed.

Body size and form of children of predominantly black ancestry living in West and Central Africa, North and South America, and the West Indies.

Stature, sitting height, hip width, arm and calf circumferences and body weight have been measured in black children of Richland County, South Carolina. Lower limb height and three indices of body shape were obtained from the measurements. Sample size exceeded 200 for each of five age-sex groups representing girls and boys aged 6 years, girls and boys aged 9 years, and boys aged 11 years. Comparisons are made with findings from previous research on children of predominantly black ancestry living in west and central Africa, the West Indies, and North, Central and South America. Black children of Richland County measured during 1974--77 are taller than black children studied since 1960 in Angola, Chad, Ghana, Liberia, Nigeria, Senegal, Uganda, Anguilla, Barbados, Cuba, Guyana, Jamaica, Nevis, St. Kitts, St. Vincent, and Surinam. Children of well-to-do black families in Accra and Ibadan are no taller or heavier than black children of Richland County taken without regard to socio-economic status. In hip width, averages for Richland County black children are larger than those for children of the Hutu and Yoruba tribes; in arm girth they are larger than children of the Hutu and Tutsi tribes. Age changes and group differences are reported for hip width relative to lower limb height, and lower limb height relative to sitting height. During childhood, the hip/lower limb index decreases, and the lower limb/sitting height index increases. Almost identical hip/lower limb indices characterize black populations in Africa, Cuba, and the United States.

Mycoses imported from the West Indies. A report of three cases.

There have been isolated case reports of deep fungal infections from the Caribbean area but little is known about the distribution of mycoses there. Three cases, one of mycetoma, one of chromomycosis, one of histoplasmosis, are described. Their management and the advantages and disadvantages of treatment outside the area of origin are discussed.

An epizootic of bovine tuberculosis in Barbados, West Indies.

A 57 cow dairy herd, believed to be in excellent condition and producing well, was found to contain 30 tuberculous cattle after cervical skin testing employing bovine PPD tuberculin with the single intradermal comparative test. Testing was initiated after two cows from this herd were found at meat inspection to have tuberculosis. The reliability of bovine PPD tuberculin for testing as well as significant epidemiological, laboratory and meat inspection factors are presented.

Study of growth of Biomphalaria glabrata Say and other Planorbidae in Guadeloupe West Indies.

The growth of Biomphalaria glabrata, B. schrammi, Drepanotrema lucidum and D. kermatoides was studied in three habitatis on Guadeloupe. Theortical growth curves were calculated for each species by applying the Walford method and the von Bertalanffy equation. On Guadeloupe, the growth of B. glabrata was faster in the ponds of Grand Terre than in the small high altitude streams of Basse Terre. There is good correlation between the observations made in Guadeloupe and previous data obtained on Pureto Rico and St Lucia.

Avian encephalomalacia in Barbados, West Indies: a description of spontaneous field cases with feed analyses.

The clinical, necropsy and histopathological findings in four natural outbreaks of encephalomalacia are reported. Feed analyses implicated low levels of vitamin E as the probable cause of the condition. Treatment with vitamin E has proved to be very effective. The instability of vitamin E in animal feed ingredients during long periods of shipment into the Caribbean may be important in the pathogenesis of the disease.

Quality control in laboratory investigations on Schistosoma mansoni in St. Lucia, West Indies. Maintenance of artificial prevalence as a laboratory aid.

A method is described of maintaining an apparent S. mansoni prevalence rate of 10% in an area estimated to have a natural rate of below 5% following two chemotherapy campaigns. To sustain interest and therefore accuracy among microscopists engaged on screening, known S. mansoni-positive stools were seeded, without their knowledge, among those collected in the field. The problems of achieving a desired level of seeding, and of a possible further dimension of the scheme are discussed.
