In the surgical history of hepatic hydatid disease, multiple scolicidal agents have been used for sterilization of the cyst contents. However, none of these agents can be safely used, because most have unacceptable side effects, such as toxicity, caustic sclerosing cholangitis, bile duct stricture, and hypernatremia. Protoscolices were aseptically removed from liver hydatid cysts obtained from sheep slaughtered at the municipal abattoir in Kahramanmaras, Turkey. In this study, the effects of 0.9% NaCl (control group), 20% NaCl (hypertonic saline), 20% silver nitrate, albendazole 20 mg/cm3, 50% dextrose (hypertonic glucose), and 20% mannitol and aminomix-1 solutions on echinococe cysts were investigated under in vitro conditions. After 5, 10, 15, 20, 25, 30, 45, and 60 min for each concentration, the first 100 protoscolices were counted on the 10x microscopical field. Protoscolices, which showed positive staining by eosine were considered as dead ones. The averages of dead and total protoscolices were calculated. Our results showed that all observed protoscolices were dead after the treatments by 20% silver nitrate in 20 min, by 50% dextrose and by aminomix-1 solution in 30 min, and by 20% NaCl and by 20% mannitol in 45 min. Albendazole at 20 mg/cm3 was observed to lead to death of 65% of protoscolices in the first 5 min and 70% of protoscolices at the end of 60 min. Compared with 0.9% NaCl (saline), all of these scolicidal agents were significantly effective (p < .05). Aminomix-1, 20% mannitol, and 50% dextrose solutions may be used in percutaneous and surgical treatment of hydatid cyst. They may be preferred because they are readily available, can be administered intravenously, and have an equal or greater effectiveness than 20% hypertonic saline.
Our purpose was to investigate associations between adenosine deaminase (ADA), superoxide dismutase (SOD), and catalase (CAT) activities and H. pylori.Ninety-nine patients were studied. Eight antral mucosal biopsies were taken for biochemical assessment of ADA, CAT, AND SOD activity and histological assessment. H. pylori density wAS evaluated according to the updated Sydney system. Patients were divided into three groups according to Sydney classification. ADA activity was found to be higher in patients having H. pylori in the present study. Also, ADA activity was higher in patients with a severe density of H. pylori. SOD level was found to be significantly higher with increased H. pylori density in our study (P < 0.05). In addition, SOD activity was higher in it H. Pylori-positive than H. pylori-negative patients. We did not find CAT activity in some antral tissue specimens. The significantly high levels of ADA activity in patients with H. pylori infection may reflect the regulator role of ADA in acid secretion. The higher ADA level with increased H. pylori density and H. pylori positivity indicate the probable malign lymphoid process of the stomach. But these findings must be confirmed with larger studies that include different gastric lesions.
We aimed to evaluate the effect of different parameters on survival in patients with gastric adenocarcinoma who underwent D2 lymph node dissection with more than 15 lymph nodes. Methods: A total of 161 patients with gastric adenocarcinoma, who underwent curative gastrectomy and had more than 15 lymph nodes dissected between January 2001 and January 2015, were retrospectively evaluated. A hundred and forty-six patients were included in the study. Results: The mean follow-up period was 24 (12-102) months and the mean survival time was 818.80±692.42 (66-3065) days. Gender, age, lymphovascular invasion and perineural invasion, tumor differentiation and histology were not found to have a statistically significant effect on overall survival. Length of hospital stay, tumor location, extent of surgery, chemotherapy, tumor stage (T category), total number of harvested lymph nodes, number of metastatic lymph nodes, lymph node status (N status), percentage of lymph node positivity, metastatic lymph node ratio and stage were found to have a statistically significant effect on overall survival. Conclusion: Having distally located tumor, having chemotherapy, higher total number of harvested lymph node and lower N category were better prognostic factor for overall survival in gastric cancer patients having curative resection with more than 15 lymph nodes harvested.
Background/Aims: There may be various factors that determine gastroesophageal reflux disease (GERD) as a result of hiatal hernia (HH) (such as the size of the hernia, age, other host and environmental factors) and the presence of protective factors to explain the absence of reflux disease should not be ignored. Helicobacter pylori (Hp) infection can prevent the development of GERD or cause it. This study aimed to determine whether Hp colonized in the stomach and hernia affects the development of erosive esophagitis (EE) in patients with HH. Materials and Methods: In this case-controlled study, 111 patients with HH were eligible for the study. Study group with EE (n = 61, 55%) and control group without EE (n = 50, 45%) were formed. Groups were compared for gastric Hp and Hp in the hernia. Results: While the frequency of Hp in the antrum was 55.7% in the group with EE, it was 30% in the control group (p = 0.01, OR: 2.94 in 95% CI 1.34–6.46). The rates in terms of HP frequency in the corpus were 43.6% and 32.1%, respectively, (p = 0.45). Hp colonization in HH was detected in 18 cases (29.50%) and 14 cases (28%), respectively, (p = 0.86). In regression analysis, antral Hp was found to be effective in the development of EE (p = 0.01). Conclusion: As a result of this study, we think that antral Hp may have a causative role in the development of reflux esophagitis, but the presence of Hp in HH does not have an effective role in reflux esophagitis formation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
