To assess the suitability of drinking water, sanitary inspection of surroundings of the sources was conducted, membrane filtration technic was used to trap the microorganisms in the water sample and other standard microbiological technics were applied to check the heterotrophic plate counts, total coliforms, fecal coliforms and some pathogenic bacteria in the samples. It was observed that there were no delineated protection zones around many boreholes (61.19%) and in almost all hand dug wells;thus, hand dug wells were pruned to more contamination than boreholes. Heterotrophic plate counts of boreholes were significantly different between (p < 0.0001) zones in dry and rainy seasons. Total coliforms per 100 ml varied significantly (p < 0.001) between the two seasons both in boreholes and hand dug wells. Fecal coliforms were significantly absent in some boreholes, but significantly present in all hand dug wells with the presence of <i>E. coli</i> 157H in some. Risk assessment of factors contributing to water contamination showed that: pumps manipulation with feet, other sources of contamination such as wastewater dumps, within 10m were significantly associated to boreholes contamination with <i>Salmonella</i> spp, <i>Staphylococcus aureuse</i>, fecal coliform (p = 0.01);in hand dug wells, presence of latrine or septic tank soak-away within 10 m of the wells, poor depth and lack of internal lining, uncapped wells, presence of trees near the wells, animal and birds feces, were significant and associated to contamination with <i>Salmonela</i> spp., <i>B. cepaceae, S. aureus E. coli</i> 1 (p < 0.05). Generally water collection points are marked with very poor sanitary conditions and this situation may not change unless the contaminating risk factors are fixed and sanitary measures are taken.展开更多

METHODS: A total of 4471 patients (48.3% female) out of 4863 attended the Samatya hospital in Istanbul (June 1999 - October 2003) were included. The records of H pylori status (CLO-test), endoscopic f indings of GU, DU and gastritis, personal habits (smoking, alcohol intake) and medication [non-steroidal anti-inflammatory drugs (NSAIDs), aspirin intake] were analyzed using multi-way frequency analysis. RESULTS: We have found that GU in the presence of H pylori had significant association with aspirin (P = 0.0001), alcohol (P = 0.0090) and NSAIDs (P = 0.0372). DU on the other hand had significant association with aspirin/ smoking/NSAIDs (P = 0.0259), aspirin/alcohol (P = 0.0002) and aspirin/smoking (P = 0.0233), also in the presence of H pylori. In the absence of H pylori GU had significant association with alcohol/NSAIDs (P = 0.0431), and NSAIDs (P = 0.0436). While DU in the absence of H pylori had significant association with smoking/alcohol/ NSAIDs (P = 0.0013), aspirin/NSAIDs (P = 0.0334), aspirin/alcohol (P = 0.0360). CONCLUSION: In the presence of H pylori, aspirin, alcohol and NSAIDs intake act as an independent risk factors that had an augmenting impact on the occurrence of GU and only together on the occurrence of DU in Turkish patients.展开更多

Methods The clinical features and preliminary epidemiologic findings among 30 patients with confirmed H1N1 virus infection who developed into acute respiratory failure for ventilatory support were investigated. Results A total of 30 patients(37.43 ± 18.80 years old) with 2009 influenza A(H1N1) related acute respiratory distress syndrome(ARDS) received treatment with mechanical ventilation, 15 cases of whom were male and 17 cases died of ARDS. Fatal cases were significantly associated with an APACHE Ⅱ score(P = 0.016), but not with PaO 2 /FIO 2(P = 0.912) and chest radiograph(P = 0.333). The most common complication was acute renal failure(n = 9). Five patients received extracorporeal membrane oxygenation(ECMO), 3 of whom died and the others survived. The major causes of death were multiple organ dysfunction syndrome(MODS)(39%), intractable respiratory failure(27%) and sepsis(20%). Conclusions Most patients with respiratory failure due to influenza A(H1N1) virus infection were young, with a high mortality, particularly associated with APACHE Ⅱ score, secondary infection of lung or type 2 diabetes mellitus.展开更多

Because of the margins of error, the obstetrician must take into account, in addition to ultrasound, the constitutional and acquired factors of the mother in order to be able to prevent the complications expected during the delivery of a large fetus. Material and method: We carried out a cross-sectional, descriptive, 12-month study in a level 2 hospital in southern France (Montélimar). The aim of the study was to assess the prevalence of macrosomia, to identify the epidemiological characteristics of the patients, to specify the management of obstetrics and complications in this hospital. Results: We recorded 141 births with a weight greater than or equal to 4000 g. That is a rate of 7.95%. The average age of our patients is 30 years. Half of them had a BMI of less than 25 and were not diabetic. 75% of the patients gave birth by a low-dose route. The sex ratio of the children is male to female 2:1. The main maternal complications were the perineovaginal tears (39 cases) and the hemorrhages of the deliverance (6 cases). Conclusion: The delivery of macrosomia is not uncommon at the Hospital Center of Montélimar. It predominates among Caucasians. Usual risk factors have rarely been found. Overall management was without major complications for both the mother and the child.展开更多
