A significant increase was detected in both urine and serum CEA levels with bladder carcinoma compared to control cases. Urinary CEA was significantly elevated in 86% of bilharzial versus 62% in nonbilharzial bladder carcinoma. Only 10.5% of control cases had urinary CEA elevation. The mean urinary CEA in bilharzial was higher than that of nonbilharzial carcinoma, but the difference was not statistically significant. There was a definite relationship between urine CEA and the stage of malignancy; the higher the stage, the higher the level of urine CEA. No relationship could be detected between the stage of malignancy and serum CEA, or between the grades of malignancy and urine or serum CEA levels. In conclusion, urinary CEA is more useful than serum CEA in the early detection of bilharziasis-associated urothelial carcinoma.","PeriodicalId":87458,"journal":{"name":"Tanzania health research bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4314/thrb.v8i3.45108","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"27246614","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}

This study was carried out to compare the indications for lumbar puncture and findings of cerebrospinal fluid examination in children admitted to Muhimbili National Hospital (MNH) in Dar-es-salaam, Tanzania and Kilifi District Hospital (KDH) in Kenya. Records of all children admitted to the paediatric wards of the two hospitals from 1st November 2004 to 30th April 2005 with suspected central nervous system infections and had LPs performed were analysed. Overall, 8,741 paediatric admissions were recorded in the two hospitals (Muhimbili = 6,228; Kilifi = 2,513). Of these, 607 (6.9%) had a LP performed; 154 out 6,228 (2.5%) in MNH and 453 out of 2,513 (18.0%) in KDH. LPs were performed less frequently in Muhimbili than in Kilifi Hospital. The most common indications for LP at MNH were convulsions (62.5%), neck stiffness (14.3%) and prostration (17%), whereas at KDH were convulsions (56.3%), neck stiffness (7.3%) and prostration (22.1%). The bacterial isolates were rarely (23%) obtained on culture at both hospitals. Streptococcus pneumonaie and Salmonella species were the commonest causes of pyogenic meningitis. In conclusion, the rate of LP performance in the two hospitals is low. There is need therefore to improve the rates of LP and the isolation of bacterial pathogens from cerebrospinal fluid cultures. Other possible causes for meningitis such as viruses need to be investigated.","PeriodicalId":87458,"journal":{"name":"Tanzania health research bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4314/thrb.v8i1.14263","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26324325","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}

A total of 270 pregnant women who gave birth to singleton deliveries and their consecutive newborns were randomly selected from among women who were attending one antenatal clinic. Average weight gains in second and third trimesters were 2.45 +/- 0.68 and 2.14 +/- 0.43 kg, respectively (a total of 4.59 +/- 1.11 kg) for the two trimesters. Weight gains per week were 0.47 +/- 0.16 and 0.33 +/- 0.13 kg for the second and third trimesters, respectively. Weight gain in the two trimesters was lower than the expected value for the same period. Results from Pearson correlation analysis found a positive correlation (P < 0.001) between birth weight and variables such as maternal age, gestational period, parity, weight gain in both second and third trimester, birth length and sex of an infant. Multiple regression analysis indicated that birth weight (dependent variable) was significantly affected by maternal weight gain in the third trimester, maternal age (both at P < 0.05) and birth length (P < 0.001). The incidence of low birth weight was about 8% and was significantly higher among infants of teenager mothers. It appears that despite of possibility of some physiological adaptations, which tend to protect the foetus when the woman is subjected to inadequate weight gain during pregnancy, weight gains in the second and third trimesters are important in determining the birth weight.","PeriodicalId":87458,"journal":{"name":"Tanzania health research bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4314/thrb.v8i1.14270","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26323636","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}
