Prevalence of hepatitis B virus (HBV) markers and human immunodeficiency virus (HIV) in employees of a blood transfusion centre.

Blood bank staff, 8 out of 25 (32%) have been exposed to hepatitis B virus (HBV) and the prevalence of HBV markers in blood bank employees handling high risk subjects show hepatitis B surface antigen (n = 1), hepatitis B surface antibody (n = 7), hepatitis B core antibody (n = 6) and combined hepatitis B surface antibody and hepatitis B core antibody (n = 6) seropositivity but all are negative to human immunodeficiency virus (HIV). Serum alanine aminotransferase was raised in the employees than normal subjects and it is suggestive of sub-clinical hepatitis. The employees of blood bank should be trained for proper handling of test materials and must be periodically monitored for HBV and HIV. Immunisation for HBV is mandatory only for the employees of transfusion centre which handles high risk subjects.

Kwashiorkor and marasmus: changing hospital incidence of syndromic presentation (1957-88).

This clinico-epidemiological study was undertaken to substantiate the impression that the pattern of clinical presentation of protein-energy malnutrition causing kwashiorkor-marasmus syndrome (KMS) is changing over time. An analysis of data for the period 1964-88, obtained from the specialised Pediatric Clinic of the Calcutta School of Tropical Medicine serving mostly the city slums showed decrease (p less than 0.01) in the incidence of chronic edematous forms of severe KMS, less decrease (p less than 0.05) in the incidence of mild-moderate KMS and increase (p less than 0.01) in the incidence of nutritional marasmus and of chronic very severe forms of KMS characterised by extreme retardation in growth and development. Incidentally, a rising incidence of rickets was observed. In the hospitalised cases (1957-88) these observations were corroborated. Data for 1985-88 of NRS Medical College Hospital, Calcutta, a general hospital serving the city as well as the neighbouring rural areas, showed that among the hospitalised city children edematous KMS was proportionately fewer than marasmus. The situation was reverse in the children from the rural areas. The observations suggested that the syndromic presentation of KMS is changing over the last three decades with some rural-urban differences for which only some recent data could be available.
