| 1 | Protective effects of intravenous anesthetics on kidney tissue in obstructive jaundice显示文摘AIM:To evaluate the protective effects on kidney tissue of frequently used intravenous anesthetics(ketamine,propofol,thiopental,and fentanyl)in rats with obstructive jaundice.METHODS:There is an increased incidence of postoperative acute renal failure in patients with obstructive jaundice.Thirty-two Wistar-albino rats were randomly divided into four equal groups.Laparatomy was performed on each animal in the four groups and common bile ducts were ligated and severed on day 0.After 7 d,laparotomy was again performed using ketamine,propofol,thiopental,or fentanyl anesthesia whose antioxidative properties are well known in oxidative stress in a rat liver model of obstructive jaundice.After 2 h,the rats were sacrificed.Renal tissue specimens were analyzed for catalase,superoxide dismutase and malondialdehyde enzymes activities.All values are expressed as the mean±SD.P values less than 0.05 were considered statistically significant.RESULTS:All animals survived without complications until the end of the study.Enlargement in the bile duct and obstructive jaundice were observed in all rats.Catalase was found to be significantly lower in the fentanyl group than in the ketamine(P=0.039),propofol(P=0.012),and thiopental(P=0.001)groups.Superoxide dismutase activities were similar in all groups(P>0.05).Malondialdehyde was found to be significantly lower in the ketamine group than in the propofol(P=0.028),thiopental(P=0.002)and fentanyl(P=0.005)groups.Malondialdehyde was also lower in the fentanyl group than in the thiopental group(P=0.001).The results showed that obstructive jaundice sensitizes renal tissue to damage under the different anesthetics.CONCLUSION:Among the agents tested,ketamine and propofol generated the least amount of oxidative stres on renal tissues in this rat model of obstructive jaundice created by common bile duct ligation.The importance of free radical injury in renal tissue in obstructive jaundice under different intravenous anesthetics during hepatobiliary and liver transplant surgery should be considered for prevention of postoperative acute renal failure. | Sinan Hatipoglu Huseyin Yildiz Ertan Bulbuloglu Ismail Coskuner Ergul Belge Kurutas Filiz Hatipoglu Harun Ciralik Mehmet Sait Berhuni | 2014 | World Journal of Gastroenterology2014，20，12： | 9 |
| 2 | Assessment of clinical and pathological features of patients who underwent thyroid surgery: A retrospective clinical study显示文摘AIM To evaluate whether there was any correlation between the clinical parameters and final pathological results among patients who underwent thyroid surgery. METHODS We retrospectively analyzed parameters, including age, sex, complete blood cell count parameters, nodule diameter, nodule localization, thyroid function testing, and pathology reports, in patients who underwent thyroid surgery. The patients were divided into malignant (n = 92) and benign (n = 413) groups depending on the final pathological results. Both groups were compared for demographic and clinicalparameters. The Kolmogorov-Smirnov normality test was used to determine if the quantitative variables had a normal distribution. The nonparametric MannWhitney U test was used to compare quantitative data that were not normally distributed, and Pearson's chisquared test was used to compare the qualitative data. The correlation between the final pathological results and fine-needle aspiration biopsy findings was calculated using the cross-tabulation method.RESULTS This study included 406 women and 99 men aged between 15 and 85 years. No significant differences were found between the groups with respect to age, sex, white blood cell count, neutrophil count, lymphocyte count, thrombocyte count, red cell distribution width, platelet distribution width, mean platelet volume, platecrit, nodule localization, and thyroid function testing. On the other hand, there were significant differences between the groups with respect to nodule size (P = 0.001), cervical lymphadenopathy(P = 0.0001) and nodular calcification (P = 0.0001). Compared with the malignant group, the benign group had a significantly greater nodule size (35.4 mm vs 27.6 mm). The best cut-off point (≤ 28 mm) for nodule size, as determined by the receiver operating characteristic curve, had a sensitivity and specificity of 67.7% and 64.4%, respectively. The correlation between fine-needle aspiration biopsy and the final pathological results was assessed using the cross-table method. The sensitivity and specificity of fine-needle aspiration biopsy were 60% and 98%, respectively.CONCLUSION This study showed that significant differences existed between the malignant and benign groups with regard to nodule size, cervical lymphadenopathy, and nodular calcification. | Arif Emre Sami Akbulut Mehmet Sertkaya Muharrem Bitiren Ilhami Taner Kale Ertan Bulbuloglu Cemil Colak | 2018 | World Journal of Clinical Cases2018，6，3： | 2 |

| 4 | Dysphagia lusorium in elderly:A case report显示文摘AIM: Late unset of dysphagia due to vascular abnormalities is a rare condition. We aimed to present a case of right subclavian artery abnormalities caused dysphagia in the elderly.METHODS: A 68-year-old female was admitted with dysphagia seven months ago. Upper endoscopic procedures and routine examinations could not demonstrate any etiology. Multislice computed thorax tomography was performed for probable extra- esophagial lesions.RESULTS: Multislice computed thorax tomography showed right subclavian artery abnormality and esophagial compression with this aberrant artery.CONCLUSION: Causes of dysphagia in the elderly are commonly malignancies, strictures and/or motility disorders. If routine examinations and endoscopic procedures fail to show any etiology, rare vascular abnormalities can be considered in such patients. Multislice computed tomography is a usefull choice in such conditions. | Bulent Kantarceken Ertan Bulbuloglu Murvet Yuksel Ali Cetinkaya | 2004 | World Journal of Gastroenterology2004，10，16： | 0 |
