The Effect of Tobacco Snuff Consumption on Liver Enzymes

This study was designed to investigate the changes in liver biochemical profile following oral tobacco dust ingestion. Adult Wistar rats (42) weighing 150-300g were involved. They were divided into four groups; group A serving as control, while groups B, C and D served as the test groups. The test groups were further divided into four groups (B1, C1, D1; B2, C2, D2; B3, C3, D3; and B4, C4, D4) representing four experimental phases/duration of 2, 4, 6 and 8 weeks respectively. The rats were fed with varying doses of tobacco dust mixed with potash. At the end of each phase, the animals were sacrificed and blood sample collected into lithium heparin and EDTA containers. Liver parameters (AST, ALT, ALP and GGT) were assayed and the results obtained showed statistically significant impairment of liver function. There was significant increase (p<0.05) in serum AST, ALT, and GGT levels in the different phases when the test groups were compared with the control. However, ALP shows no statistically significant increase in all the groups throughout the experiment. The results of this study suggest that potash-tobacco dust (local tobacco snuff) is toxic to the liver and the observed changes were dose and duration dependent.Keywords: tobacco, potash, liver function, liver enzymes

Global patient outcomes after elective surgery: prospective cohort study in 27 low-, middle- and high-income countries.

BACKGROUND: As global initiatives increase patient access to surgical treatments, there remains a need to understand the adverse effects of surgery and define appropriate levels of perioperative care. METHODS: We designed a prospective international 7-day cohort study of outcomes following elective adult inpatient surgery in 27 countries. The primary outcome was in-hospital complications. Secondary outcomes were death following a complication (failure to rescue) and death in hospital. Process measures were admission to critical care immediately after surgery or to treat a complication and duration of hospital stay. A single definition of critical care was used for all countries. RESULTS: A total of 474 hospitals in 19 high-, 7 middle- and 1 low-income country were included in the primary analysis. Data included 44 814 patients with a median hospital stay of 4 (range 2-7) days. A total of 7508 patients (16.8%) developed one or more postoperative complication and 207 died (0.5%). The overall mortality among patients who developed complications was 2.8%. Mortality following complications ranged from 2.4% for pulmonary embolism to 43.9% for cardiac arrest. A total of 4360 (9.7%) patients were admitted to a critical care unit as routine immediately after surgery, of whom 2198 (50.4%) developed a complication, with 105 (2.4%) deaths. A total of 1233 patients (16.4%) were admitted to a critical care unit to treat complications, with 119 (9.7%) deaths. Despite lower baseline risk, outcomes were similar in low- and middle-income compared with high-income countries. CONCLUSIONS: Poor patient outcomes are common after inpatient surgery. Global initiatives to increase access to surgical treatments should also address the need for safe perioperative care. STUDY REGISTRATION: ISRCTN5181700

Comparative evaluation of haemoglobin estimation amongst pregnant women in Ibadan: Hemocue – B Haemoglobin analyzer versus haemiglobincyanide (Standard) method as the gold standard

This was a comparative crossectional study that was conducted among 557 antenatal women at the University College Hospital, Ibadan, Nigeria between 1st April and 30th May 2006. The study compared the accuracy of haemoglobin estimation using an automated HemoCue B analyzer kit with a standard laboratory method (haemogloincyanide) as the gold standard. The result showed a positive correlation of HaemoCue haemoglobin results when compared with the standard methods (Pearson's correlation coefficient = 0.892; p value = 0.000). We concluded that the use of the automated HemoCue kit for haemoglobin estimation gives an objective assessment which overcomes the challenge of extra skilled manpower or power outages in rural areas thereby enhancing access to quality of care in resource poor countries Keywords: Haemocue, B analyser, Anaemia in Pregnancy, Haemoglobin estimation African Journal of Reproductive Health Vol. 12 (2) 2008: pp. 153-15

Survey Of Ketosis And Hypoproteinaemia In Slaughtered Cattle In The Sahel Region Of Nigeria

Serum ketone and total protein concentrations of 966 cattle slaughtered at the metropolitan abattoir, Maiduguri, Nigera, were estimated durng the dry and rainy months of the year. None of the sera had a titrable ketone concentration. Serum total protein (STP) concentration o
