丙型肝炎病毒(H CV)传播的危险因素随国家和地区的变化而有所不同。该文旨在探讨土耳其人群中与H CV传播有关的危险因素。研究选取1996—2002年间伊斯坦布尔大学医学院胃肠肝病科收治的H CV感染者320例,患者于住院或出院后门诊随访期间被发现血清H CV抗体阳性。对所有患者询问其感染H CV的危险因素,如输血史、手术史、住院治疗、血液透析、静脉药物注射、可疑的性接触、文身、针灸、牙科操作、修甲修脚、滴血盟誓史、割礼或包皮环切、流产、围产期危险因素等。该研究中,男性和女性患者数量及百分比分别为139例(43.4%)与181例(56.6%),… 相似文献

《自然》杂志(Nature,2006,439:248-249)1月19日报道,禽流感病毒的突变警钟已经拉响,禽流感加大了对人类的威胁。报道说,土耳其短时间内禽流感爆发给世人敲响了警钟,世界卫生组织位于伦敦的合作中心——国家医学研究院(NIMR)的科学家们已经确定了在禽流感病毒的序列中发生了3个突变,其中至少有2个使病毒更加适应人类。这些科学家们迫切地想知道这些病毒在土耳其的传播与先前在亚洲出现的禽流感病毒的传播有什么不同,他们特别关注人类之间禽流感传播的可能性。 相似文献

AIM:The eradication rate of Helicobacter pylori (H pylon) shows variation among countries and regimens of treatment.We aimed to study the eradication rates of different regimens in our region and some factors affecting the rate of eradication.METHODS:One hundred and sixty-four Hpylori positivepatients (68 males, 96 females; mean age:48±12 years)with duodenal or gastric ulcer without a smoking history were included in the study. The patients were divided into three groups according to the treatment regimens. Omeprazole 20mg, clarithromycin 500mg, amoxicillin 1g were given twice daily for 1 week (Group I) and 2 weeks (Group Ⅱ).Patients in Group Ⅲ received bismuth subsitrate 300mg,tetracyline 500 mg and metronidazole 500mg four times daily in addition to Omeprazole 20mg twice daily.Two biopsies each before and after treatment were obtained from antrum and corpus, and histopathologically evaluated.Eradication was assumed to be successful if no Hpylorus was detected from four biopsy specimens taken after treatment. The effects of factors like age, sex, Hpyloridensity on antrum and corpus before treatment, the total Hpylori density, and the inflammation scores on the rate of Hpylori eradication were evaluated.RESULTS:The overall eradication rate was 42%. The rates in groups Ⅱ and Ⅲ were statistically higher than that in group I (P<0.05). The rates of eradication were 24.5%,40.7% and 61.5% in groups Ⅰ, Ⅱ and Ⅲ, respectively. The eradication rate was negatively related to either corpus Hpylori density or total Hpyloridensity (P<0.05).The median age was older in the group in which the eradication failed in comparison to that with successful eradication (55yr vs 39yr, P<0.001). No correlation between sex and Hpylori eradication was found.CONCLUSION: Our rates of eradication were significantly lower when compared to those reported in literature.We believe that advanced age and high Hpyloridensity are negative predictive factors for the rate of Hpylorieradication. 相似文献

The aim of the study was to investigate the functional performance in children with spina bifida, using the Pediatric Evaluation of Disability Inventory(PEDI) to look into capacity of twenty-eight children with spina bifida with lesions at different levels in different dimensions of selfcare, mobility and social function. Mean age of the patients was 3.5 ± 2.3(1–10) years. In the muscle test carried out, 13 patients(44.8%) had no movements including pelvic elevation in lower extremity muscles and they were at level 5. Sixteen patients(54%) were non-ambulatory according to the Hoofer ambulation classification. Raw and scale scores in the self-care, mobility and social function domains both in the functional skill scale and in the caregiver scale were found to be lower compared to the data of the normal population. A statistically significant correlation was observed in the self-care values of the Functional Skills Scales and the Caregiver Assistance Scale measurements, which was positive for age and negative for Functional Ambulation Scale and muscle test(P 0.05). A positive relation was found between the Functional Skills Scales-mobility area and age while a negative relation was observed between Functional Ambulation Scale and muscle test(P 0.005). A negative relation was also found between Caregiver Assistance Scale-mobility and Functional Ambulation Scale and muscle test(P 0.005). In our study, the functional performance of the children was found to be low. Low-level lesions, encouraging muscular strength and independence in mobility are all very important factors for functional independence. 相似文献
