We aimed to present our clinical experience with FG treatment. Fourniers gangrene (FG) is a rare but serious disease characterized by progressive necrosis in the genitourinary and perineal region. The retrospective study included 43 patients. Patients were divided into 2 groups as survivors and nonsurvivors. Included in the analysis were data pertaining to demographics, predisposing factors, comorbidities, results of bacteriologic analyses, number of debridements, duration of treatment, FG Severity Index (FGSI) score, fecal diversion methods (trephine ostomy or Flexi-Seal Fecal Management System-FMS), and dressing methods (wet or negative aspiration system). In the nonsurvivor group, urea, WBC, and age were significantly higher, whereas albumin, hematocrit, platelet count, and length of hospital stay (LOHS) were significantly lower compared to the survivor group. Mean FGSI was lower in survivors in comparison with nonsurvivors (5.00 ± 1.86 and 10.00 ± 1.27, respectively; P < 0.001). We conclude that FGSI is an important predictor in the prognosis of FG. Vacuum-assisted closure (VAC) should be performed in compliant patients in order to enhance patient comfort by reducing pain and the number of dressings. Fecal diversion should be performed as needed, preferably by using FMS. The trephine ostomy should be the method of choice in cases where an ostomy is necessary.

OBJECTIVE Peptic ulcer perforation continues to be a major surgical problem. In this study, risk factors that influence morbidity and mortality in perforated peptic ulcer disease were examined. MATERIAL AND METHODS Files of 148 patients who were included in the study due to peptic ulcer perforation between January 2006 and December 2010 were retrospectively analyzed. Data regarding age, gender, complaints, time elapsed between onset of symptoms and hospital admission, physical examination findings, co-morbid diseases, laboratory and imaging findings, length of hospital stay, morbidity and mortality were recorded. RESULTS The study group included 129 (87.2%) male and 19 (12.8%) female patients. The mean age was 51.7±20 (15-88) years. Forty five patients (30.4%) had at least one co-morbid disease. In the postoperative period, 30 patients (20.3%) had complications. The most common complication was wound infection. Mortality was observed in 27 patients (18.2%). The most common cause of mortality was sepsis. Multivariate analysis revealed age over 60 years, presence of co-morbidities and Mannheim peritonitis index as independent risk factors for morbidity. Age over 60 years, time to admission and Mannheim peritonitis index were detected as independent risk factors for mortality. CONCLUSION Early diagnosis and proper treatment are important in patients presenting with peptic ulcer perforation.Results: The study group included 129 (87.2%) male and 19 (12.8%) female patients.

Background The aim of this study was to investigate the protective effects of L-glutamine (GLN) against liver and kidney injury caused by acute toxicity of deltamethrin (DLM). Material/Methods Thirty-two rats were indiscriminately separated into 4 groups with 8 rats each: control group (distilled water; 10 ml/kg, perorally [p.o.]), DLM group (35 mg/kg p.o. one dose.), GLN group (1.5 gr/kg, p.o. single dose.) and DLM (35 mg/kg p.o. one dose.) + GLN group (1.5 gr/kg, p.o. one dose after 4 hours.). Testing for total antioxidant status (TAS), total oxidant status (TOS), interleukin-1 beta (IL-1β), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) analyses were performed on tissue samples, and alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), urea, and creatinine were analyzed on serum samples. Liver and kidney samples were histopathologically analyzed. Results The TOS level in liver was significantly higher in the DLM group than in the control group, and the level in DLM+GLN group was considerably lower than in the DLM group. The TAS level in the DLM+GLN group was considerably higher than in the control and DLM groups. The TAS level in kidney tissues was considerably lower in the DLM group than in controls, but was similar to other groups. Histopathological analyses of liver tissues established a significant difference between DLM and DLM+GLN groups in terms of grade 2 hepatic injury. However, no significant difference was found between DLM and DLM+GLN groups in terms of kidney injury. Conclusions Glutamine leads to significant improvement in deltamethrin-induced acute hepatotoxicity in terms of histopathologic results, tissue oxidative stress parameters, and serum liver function marker enzymes.

ABSTRACT Introduction: Hepatic ischemia/reperfusion injury may occur after large tumor resection and liver transplantation procedures. Nitric oxide was shown to have protective effects on ischemia/reperfusion injury. Nebivolol is a compound that has been reported to improve nitric oxide release. We evaluated the effects of nebivolol in a rat liver ischemia/reperfusion model. Methods: A total of 40 rats were randomly divided into four groups (n = 10 each). Group I underwent only laparotomy, Group II was administered nebivolol and then underwent laparotomy, Group III underwent laparotomy and hepatic ischemia/reperfusion, and Group IV was administered nebivolol and then underwent laparotomy and hepatic ischemia/reperfusion. Serum AST, ALT, urea, and creatinine levels, and TAS and TOS levels of liver, lung, and kidney tissues were determined. Histopathological determination was also performed. Results: Nebivolol significantly reduced liver function tests in group IV, but it did not improve renal functions. Oxidative stress and abnormal histopathological findings were found to be reduced in liver tissue in group IV. Although the oxidative stress was increased after hepatic ischemia/reperfusion, nebivolol could not reduce the oxidative stress in kidney tissue. There were no significant differences between group III and group IV in terms of the histopathological changes in kidney tissue. There were no significant differences in lung tissue between the groups. Conclusions: The results of this study suggest that nebivolol has protective effects on liver but not on distant organs in a hepatic ischemia/reperfusion injury model. These experimental findings indicate that nebivolol may be useful in the treatment of hepatic ischemia/reperfusion injury.

INTRODUCTION We aimed to analyze the approaches to the diagnosis and treatment of patients with fascioliasis in light of current literature. METHODOLOGY Thirty-nine patients with fascioliasis admitted to the Surgery Clinic of Dicle Medical Faculty (Turkey) were included in this study. The demographic, clinical, diagnostic, treatment and outcome data were analyzed retrospectively. RESULTS Abdominal pain (n = 37; 95%) and eosinophilia (n = 31; 79%) were the most common findings. Twenty-seven patients were diagnosed by clinical and radiological findings. Patients were treated with triclabendazole. Thirty-six (92.4%) of the patients improved after medical treatment. CONCLUSIONS The presence of typical clinical, laboratory and radiological findings is sufficient for diagnosis. Triclabendazole administration is often an effective treatment, with improvements occurring over the course of a few months.

Abstract Aim : This study aimed to investigate protective effects of ellagic acid on lungs in an experimental obstructive jaundice model. Methods : Four groups were established, each consisting of ten randomly selected rats: Group 1: sham, Group 2: ellagic acid, Group 3: obstructive jaundice, and Group 4: obstructive jaundice + ellagic acid. Ellagic acid was administered orally at a dose of 60 mg/kg/day to group 2 and 4. The animals were sacrificed eight days later. The total oxidative status and the total antioxidant capacity in their lung tissue were determined, and malondialdehyde levels in their blood were measured. Histopathological changes in the lungs were examined. Results : In the obstructive jaundice group treated with ellagic acid, there was a decrease in malondialdehyde levels and a reduction in the total oxidative status and the oxidative stress index, whereas the total antioxidant capacity increased (p < 0.001). The histopathological examination showed that neutrophil leukocyte infiltration and edema formation decreased and destruction of lung parenchyma disappeared following the treatment with the ellagic acid (p < 0.05). Conclusion : This study shows that ellagic acid has a protective effect against oxidative damage in lung tissue in obstructive jaundice.

The aim of this study was to analyze the presence of malignancy in patients with Hashimotos thyroiditis and to investigate the reliability of preoperative fine-needle aspiration biopsy (FNAB). The retrospective study included 44 patients who were operated on for nodular goiter between December 2010 and October 2011. The patients underwent thyroidectomy following a cytologic analysis plus FNAB. Hashimotos thyroiditis was confirmed on histopathology in all patients. FNAB results were defined as benign in 14 (31.8%), suspicion for malignancy in 17 (38.6%), malignant in 9 (20.5%), and inadequate in 4 (9.1%). Following the thyroidectomy, presence of papillary thyroid carcinoma and follicular variant of papillary thyroid carcinoma were detected in 10 patients (22.7%) and 1 (2.3%) patient, respectively. The FNAB results were interpreted in terms of malignancy, which revealed the sensitivity as 80%; specificity, 40%; false positives, 69.2%; false negatives, 14.3%; positive predictive value, 31.8%; negative predictive value, 85.7%; and diagnostic accuracy, 50%. The coexistence of Hashimotos thyroiditis with papillary thyroid carcinoma is quite common. The FNAB results for such cases are hard to evaluate, and they are likely to increase the number of false positives.

Our objective for this study was to discuss the usability of mean platelet volume, which is associated with numerous vascular pathologies, in the early diagnosis of acute mesenteric ischemia. Acute mesenteric ischemia is an uncommon, life-threatening clinical condition mostly seen in the elderly. Early diagnosis of acute mesenteric ischemia and correction of blood circulation before necrosis occurs are important factors affecting prognosis. A total of 95 patients who underwent emergency surgery for acute mesenteric ischemia and 90 healthy volunteers as control group were included in this study. Age, gender, hemoglobin values, white blood cell counts, mean platelet volume, and platelet counts are recorded for evaluation. The mean platelet volume values were significantly higher in patients with acute mesenteric ischemia than in the controls (9.4 ± 1.1 fL and 7.4 ± 1.4 fL, respectively; P < 0.001). Receiver-operating characteristic analysis demonstrated a cutoff value of mean platelet volume as 8.1 fL (area under the curve, 0.862), a sensitivity of 83.2%, and a specificity of 80%. As a result, in the patients who are admitted to the hospital with acute nonspecific abdominal pain and suspected of having acute mesenteric ischemia, high mean platelet volume values in routine hemograms support the diagnosis of acute mesenteric ischemia.

BACKGROUND The purpose of this study was to investigate the effect of Sulforaphane on ischemia/ reperfusion (IR) injury of the liver and distant organs resulting from liver blood flow arrest. MATERIALS AND METHODS Fourty Wistar rats were assigned into four groups, each included 10 rats were used. Group I as only laparatomy, Group II laparatomy and Sulforaphane application, Group III hepatic IR; and Group IV as hepatic IR and Sulforaphane application group. Animals were subjected to liver ischemia for 30 min and then reperfusion is started. 5 mg/kg Sulforaphane was applied via oral lavage 15 minutes before initiating the experimental study. Blood samples were taken from the animals for biochemical analysis at 60th minutes of the experiment in the first and second groups; 30 minutes after beginning reperfusion in the third and forth groups. Simultaneously, liver, lung and kidney tissues were sampled for biochemical and histopathological examinations. RESULTS The administration of sulforaphane significantly reduced the serum TOA and liver TOA levels, increased the serum TAC and liver TAC levels and also decreased The OSI and liver OSI levels. In the histopathologic examination, the injury was reduced by the administration of sulforaphane. Administration of sulforaphane did not lead to any significant changes in any parameter including histopathological parameters in both the kidney and the lung. CONCLUSIONS Sulforaphane reduced the liver oxidative stress from I/R injury. A histological injury in liver was reduced by sulforaphane administration. However, there were no significant effects of sulforaphane on the remote organ injuries induced by IR.
