All tissue blocks had been embedded in paraffin 4-10 years before. The first antibody used was monoclonal antirabies nucleocapsin (N) mouse antibody (HAM). Four out of five pieces of tongue from two cases showed a large amount of granular staining indicating rabies antigen (RVAg) inside serous glandular cells, terminal nerves, muscle cells and covering epithelial cells including taste cells. In the tissue probes from the third case only minimal granular staining was found, probably due to complete absence of the serous gland. In contrast to the tongue, only a little weakly reacting material was found in 4 out of 9 probes of salivary gland, either in acini or in nerve fibres. The amount of RVAg is evidently much greater in the human tongue than in major salivary glands, whereas major salivary glands from infected dogs, foxes and skunks reportedly contain much RVAg. As the human tongue's serous gland appears to be a preferred location for RVAg, it may be a source of oral infection.</p>","PeriodicalId":76688,"journal":{"name":"The Journal of tropical medicine and hygiene","volume":"98 5","pages":"330-2"},"PeriodicalIF":0.0,"publicationDate":"1995-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18570434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three hundred and thirteen cases of S. mansoni infection (16.8%) were found. The intestinal form was the most frequent (67.4%), followed by the hepatosplenic form without pulmonary hypertension (24.9%). The intestinal form showed a smaller number of ectopic sites and a lower percentage of involvement of these sites compared to the more severe forms, particularly the hepatosplenic form with pulmonary hypertension. The distribution of the frequency of schistosomiasis mansoni cases, of the clinicopathological forms of the disease, and of the ectopic sites of S. mansoni eggs over the decades considered showed a marked reduction in all of these parameters, particularly in the more severe forms.

The countries involved are Zambia, Tanzania, Kenya and Ghana. Figures on admission, causes of death and clinical case fatality rates are presented per country and per 4-year calendar period for the most important infectious diseases. The number of admissions increased substantially in 3 of the 4 countries (50-77%) between 1976 and 1990, but admission rates (per 1,000 population per year) by much less (6-25%), indicating that a large part of the increase in the volume of services was due to population growth. The number of infectious disease admissions in Ghana, however, decreased by 12% and even more in terms of admission rates (by 42%). About 75% of all admissions in children below 15 years of age were due to infections and infection related diseases; for adults this figure was 31%. Malaria is the single most important infectious disease both in terms of admissions and as a cause of death; it has increased substantially in three of the four countries. Bacterial infections, in particular pneumonia, gastroenteritis, meningitis and tuberculosis, are also important diseases in terms of admissions and deaths. On the whole they have remained at more or less the same level in 1975-1990 in terms of both admissions and deaths. Immunizable diseases and measles, once important as causes of admissions and deaths, have declined in all countries. Case fatality rates vary substantially by type of disease. They are very high for tetanus (36.7-68.8%) and meningitis (14.7-43%), and low for malaria (0.6-4.6%). However, they vary considerably in the four countries included in the study and are usually lower in children than in adults. A need for detailed studies with good \"standardized\" hospital records is emphasized. Representative data are needed from all hospitals in a given catchment area, with defined diagnoses for diseases and details regarding age and sex. This kind of information is highly desirable for planning and operation of curative and preventive medical care in developing countries.</p>","PeriodicalId":76688,"journal":{"name":"The Journal of tropical medicine and hygiene","volume":"98 4","pages":"217-27"},"PeriodicalIF":0.0,"publicationDate":"1995-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18642830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
