7Detection of class 1 integron in Acinetobacter baumannii isolates collected from nine hospitals in Turkey显示文摘Objective:To investigate the antibiotic resistance genes inserted into class I and class 2integrons in Acinetobacler baumannii[A.baumannii)isolates obtained from nine different cities in Turkey.Methods:A collection of 281 A.baumannii clinical isolates were collected from nine diferenl state hospitals in Turkey and were confirmed as A.baumannU by conventional biochemical,API testing and bla_(-OXA-51)specific PCR.The isolates were examined by PCR for existence of class I and2 integron gene cassettes.Results:They were characterized by antimicrobial susceptibility testing and the highest resistance rates were determined for piperacillin(90.03%),ciprofloxacin(87.54%),cefepime and trimethoprim/sulfamethoxazole(81.13%).The lowest resistance rates was for cefotaxime(3.55%).class 1 integrons were detected in 6.4%(18/281)of A.baumannii strains and no class 2 integron was detected.The gene casselles of class 1 inlegrons AacCI-AAC(3)l-aadAI,AacCI-aadA1,AAC(3)-I,AAC(3)-I-AAC(3)-I-aadA1,TEM-1.AAC(3)-I-aadA1-AAC(3)-I-AAC(3)-I,AAC(3)-I-AAC(3)-I-AAC(3)-I-aadA1,AAC(3)-I-aadA1,AAC(3)-I-AAC(3)-I,AAC(3)-I-aadA1-AAC(3)-I-aadA1,AAC(3)-I-AAC(3)-I-aadA1-AAC(3)-I-aadA1 were detected in eighteen strains.The aac genes family were most frequently found integrated into the class 1 inlegrons and it was followed by aadA genes and TEM-1 genes.Conclusions:This is an extensive study on the distribulion of class 1 integron among A.baumannii in Turkey.In addition to these,two new alleles were observed.Their percentage rates of similarity to other cassettes are 95%aadA1(TK A18)and 89%,aadA 1(ANKA3).Aysegül Copur Cicek Azer Ozad Düzgün Aysegül Saral Tuba Kayman Zeynep Cizmeci Pervin Ozlem Balci Tuba Dal Mehmet Firat Ismail Tosun Yasemin Ay Alitntop Ahmet Caliskan Yelda Yazici Cemal Sandalli 2013Asian Pacific Journal of Tropical Biomedicine2013,3,9:3
8Differences in individual susceptibility affect the development of trigeminal neuralgia显示文摘Trigeminal neuralgia is a syndrome due to dysfunctional hyperactivity of the trigeminal nerve,and is characterized by a sudden,usually unilateral,recurrent lancinating pain arising from one or more divisions of the nerve.The most accepted pathogenetic mechanism for trigeminal neuralgia is compression of the nerve at its dorsal root entry zone or in its distal course.In this paper,we report four cases with trigeminal neuralgia due to an unknown mechanism after an intracranial intervention.The onset of trigeminal neuralgia after surgical interventions that are unrelated to the trigeminal nerve suggests that in patients with greater individual susceptibility,nerve contact with the vascular structure due to postoperative pressure and changes in cerebrospinal fluid flow may cause the onset of pain.Yusuf Kurtulus Duransoy Mesut Mete Emrah Akay Mehmet Seluki 2013Neural Regeneration Research2013,8,14:3
9国际卒中遗传学联盟的推荐意见(第1部分):标准化表型数据收集显示文摘与几乎所有复杂疾病一样,卒中的患病风险和临床转归也是多基因作用的[1]。探索相关基因突变有望为新型个体化治疗方法奠定基础,从而显著减少卒中对全球健康造成的毁灭性影响。为了达到足够的统计学效能以确认多个风险性等位基因,需要很大的样本量。尽管卒中是全世界范围内第二大致死病因和成年人致残的主要原因[2],但没有任何一家研究机构能独立收集到足够的样本。在认识到这一挑战之后,来自世界各地的卒中研究者们于2007年成立了国际卒中遗传学联盟( International Stroke Genetics Consortium, ISGC; http://www. strokegenetics.org),其使命是通过研究在全球多个研究机构入组的患者来识别影响卒中患病风险、临床预后和治疗效果的遗传学因素。尽管先前已取得了一些成功[3-5],仍有大量工作有待进行,这不仅是为了发现风险性等位基因从而达到卒中个体化医疗的最终目标,更是为了开发综合性卒中风险评估手段以及得到足以改变临床实践的结果[6]。根据糖尿病和冠状动脉疾病等其他复杂疾病的研究进展,为了识别与卒中相关的所有基因突变,需要100000~200000个样本。为了达到这个样本量,需要进行更为广泛的协作。Jennifer J.

11Improvement in renal functions with transcatheter aortic valve implantation显示文摘BACKGROUND & OBJECTIVES:In recent years, emerging transcatheter aortic valve implantation (TAVI) has become an alternative for surgery。 However, with advanced age, several co-morbid factors together with contrast agent usage can cause deterioration in renal function and increase in the risk of acute kidney injury (AKI) with poor prognosis in patients with AKI。 Therefore, many patients cannot benefit from this treatment。 In this study, we aim to examine the effects of TAVI on renal functions。 METHODS AND RESULTS: Seventy patients, mean age of 77.6 years, underwent TAVI between July 2011 and December 2012。 Estimated glomerular filtration rate (eGFR) was calculated by using the Cockcroft and Gault Formula。 Patients were monitored for 48 h for urine output。 Stage 1 AKI, according to the VARC-2 AKIN system, developed in only five (7.1%) of the patients after the procedure。 There was a statistically significant increase between the mean 1(st) month eGFRs before (68。2 vs。 61.0, P < 0.01) and after (68。2 vs。 63.6, P < 0.05) the TAVI in the cohort。 After TAVI (48。5 mL/min, P < 0.01) and the 1(st) month (52.1 mL/min, P < 0.01), the eGFR of the 36 (51.4%) patients diagnosed with chronic kidney disease before the procedure showed a statistically significant increase in renal functions。 The hospital mortality rate was higher in the group which developed AKI (P < 0.01)。 First month eGFR showed a more statistically significant increase than pre-TAVI eGFR (62.8 and 69.8, P < 0.05, respectively) in AKI developing patients and this difference - though statistically not significant - continued into the sixth month。 CONCLUSIONS: In this study, we showed that the treatment of aortic stenosis through TAVI allows improvement of renal functions, and that AKI rates will be lower with careful patient selection, proper pre-procedural hydration, and careful use of contrast agent。Telat Keleş Huseyin Ayhan Durmaz Sarı Aslan AN Erdoğan KE Kasapkara Bilen Bayram Akçay Bozkurt 2013Journal of Geriatric Cardiology2013,10,4:2

16Can fruit seeds and undigested plant residuals cause acute appendicitis显示文摘Objective:To investigate the relation between fruit seeds,plants residuals and appendicitis. Methods:Among cases that underwent appendectomy,the appendicitis cases having fruit seeds and undigested plant residuals in their etiology were examined retrospectively.Also, histopathological features,age,sex,and parameters of morbidity and mortality were used. Results:Fruit seed was found in one case(0.05%) with presence of pus in appendix lumen, undigested plant residuals in 7 cases(0.35%).It was determined that there were appendix inflammation in 2 of the plant residuals cases,while there were obstruction and lymphoid hyperplasia in the appendix lumen of 5 cases.No mortality was observed.Conclusions:The ratio of acute appendicitis caused by plants is minimal among all appendectomised patients, but avoidence of eating undigested fruit seeds and chewing plants well may help to prevent appendicitis.Omer Engin Mehmet Yildirim Savas Yakan Gulnihal Ay Coskun 2011Asian Pacific Journal of Tropical Biomedicine2011,1,2:2
