Abstract
BACKGROUND We aimed to examine the oral and topical effect of Oltipraz (OPZ) on fibrosis and healing after urethra injury in a rat model. METHODS In all, 33 adult Sprague-Dawley rats were divided randomly into 5 different groups: sham, urethral injury group (UI), oral Oltipraz treatment group for 14 days after urethral injury (UI+oOPZ), intraurethral Oltipraz treatment group for 14 days after urethral injury (UI+iOPZ) and only intraurethral Oltipraz treatment for 14 days without urethral injury (sham+iOPZ). Pediatric urethrotome blade was used to create the urethral injury model for the injury groups (UI, UI+oOPZ and UI+iOPZ). After 14 days of treatment, all rats were sacrificed after penectomy under general anesthesia. Urethral tissue was evaluated histopathologically for congestion, inflammatory cell infiltration and spongiofibrosis, and immunohistochemically for transforming growth factor Beta-1 (TBF) and vascular endothelial growth factor receptor2 (VEGFR2). RESULTS The congestion score was not statistically significantly different between the groups. Spongiofibrosis was distinctive in UI group and OPZ given groups. Inflammation and spongiofibrosis score were statistically significantly higher in the sham+iOPZ group compared to the sham group (P<0.05). VEGFR2 and TGF Beta-1 scores were statistically significantly higher in the sham+iOPZ group compared to the sham group (P<0.05). We did not find beneficial effect of OPZ on urethral healing. We found the harmful effect of intraurethral administration of OPZ in the group without urethral injury in compared to sham. CONCLUSIONS According to our results, we cannot suggest OPZ in the treatment of urethral injury. Future studies in this area are needed.

Abstract
Combined use of a chemotherapeutic agent and an autophagy inhibitor is a novel cancer treatment strategy. We investigated the effects of chloroquine (CQ) on lung pathology caused by both solid Ehrlich ascites carcinoma (EAC) and doxorubicin (DXR). A control group and eight experimental groups of adult female mice were inoculated subcutaneously with 2.5 × 106 EAC cells. DXR (1.5 mg/kg and 3 mg/kg) and CQ (25 mg/kg and 50 mg/kg) alone or in combination were injected intraperitoneally on days 2, 7 and 12 following inoculation with EAC cells. Lung tissue samples were examined using immunohistochemistry (IHC) for endothelial (eNOS), inducible nitric oxide synthase (iNOS) and neutrophil gelatinase-associated lipocalin (NGAL). Serum catalase (CAT), glutathione peroxidase (GPx), superoxide dismutase (SOD) and malondialdehyde (MDA) levels were measured using ELISA. We found decreased levels of iNOS and eNOS in the groups that received 1.5 mg/kg DXR alone and in combination with 25 mg/kg and 50 mg/kg CQ. Combined administration of DXR and CQ partially prevented disruption of alveolar structure. Levels of antioxidant enzymes and MDA were lower in all treated groups; the greatest reduction was observed in mice that received the combination of 25 mg/kg CQ + 1.5 mg/kg DXR. Levels of NGAL were elevated in all treated groups. We found that CQ ameliorated both EAC and DOX induced lung pathology in female mice with solid EAC by reducing oxidative stress.

Abstract
Testicular torsion is an emergency urological disease, and the treatment is immediate surgery. Despite emergency surgery, testicular damage may occur due to reperfusion. Therefore, a medical treatment to prevent this damage may be a rational idea. We aimed to evaluate the protective effect of oltipraz in testicular ischaemia/reperfusion damage. Twenty-eight Wistar-Albino rats were randomly divided into four groups. In ischaemia/reperfusion group, testicular torsion was executed, and orchiectomy was done 4 hr after detorsion with no treatment. Second group performed torsion; intraperitoneal 50 mg/kg oltipraz was applied 30 min before detorsion, and orchiectomy was performed 4 hr after detorsion. Third group applied torsion; intraperitoneal 150 mg/kg oltipraz was applied 30 min before detorsion, and orchiectomy was performed 4 hr after detorsion. Last one was the sham group. We evaluated tissue malondialdehyde (MDA), transforming growth factor-β1 (TGF-β1), superoxide dismutase (SOD), reduced glutathione (GSH) and Johnsen testicular biopsy score. There was a significant decrease in TGF-β1, GSH and MDA values in oltipraz treatment groups compared with ischaemia/reperfusion group. Oltipraz treatment has significant protective effect in testicular ischaemia/reperfusion damage. However, more clinical studies are needed to demonstrate appropriate dose and its effects.

Abstract
BACKGROUND Glanular dehiscence (GD) is one of the main complications after hypospadias surgery. There is a limited number of publications regarding GD in the literature. OBJECTIVE The aim of this work is to reveal the factors that affect GD after a literature review. EVIDENCE ACQUISITION A literature search for relevant articles was performed in database using the search term glans dehiscence without setting date range limit or any other limits. All articles related to GD after hypospadias surgery were included in this study. After collecting the information from full text articles, 71 articles were included in this systematic review. In these studies, localization of hypospadic meatus, type of surgery, and other clinical data which were thought to behave as risk factors for GD were obtained. Chi-Square test was used to evaluate the differences between the parameters, where p < 0.05 was taken as statistically significant. RESULTS After evaluating the 71 articles that met the inclusion criteria, 309 cases (3.48%) of GD after 8858 hypospadias repairs were obtained in this review. GD rates were found significantly high for proximal hypospadias (5%), two-stage hypospadia repairs (5%) and re-do hypospadias repair (8.75%) (p = 0.002, 0.022, and 0.004, respectively). Glans width <14 mm, urethral plate (UP) width <7 mm, hypospadias surgeries performed before 6 months of age and after puberty, and caudal block anesthesia increased the rate of GD. CONCLUSIONS The rate of GD increases after proximal, cripple and staged hypospadias surgeries, a glans width <15 mm and UP width <8 mm, postpubertal surgeries, and caudal anesthesia use during surgery.

Abstract
This study was performed to evaluate the effect of liraglutide on experimental testicular ischaemia reperfusion in rats in terms of biochemistry, histopathology and immunohistochemistry. A total of 28 male Wistar-Albino rats were divided randomly into 4 groups: control (7), sham (7), ischaemia-reperfusion (7) and ischaemia-reperfusion + liraglutide (7). Biochemically, Nitric Oxide, Malondialdehyde, Superoxide dismutase, Glutathione peroxidase and Catalase levels were measured in the testis. Apoptosis protease activating factor-1 and inducible nitric oxide synthase activity were evaluated immunohistochemically as well. Statistical analyses were made via the Kruskal-Wallis and Mann-Whitney U tests. In the reperfusion group, CAT and SOD values were increased (p > .05), NO and MDA values were decreased (p < .05) after administration of liraglutide. In addition, GPx values were significantly increased in ischaemia reperfusion + liraglutide administered group compared to reperfusion group (p < .05). Apaf-1 and iNOS activity were significantly decreased with the addition of liraglutide treatment to the ischaemia-reperfusion group (p < .05). First of all, we would like to say that liraglutide treatment is moderately preventive against I/R injury in testicular torsion. The anti-inflammatory, antioxidant and antiapoptotic properties of liraglutide are create a moderately protective effect as we show in this study.

Abstract
BACKGROUND Feline mammary gland tumors (FMGTs) are the third most diagnosed tumors in cats. Feline mammary gland tumors have aggressive biological behavior and poor response to both surgical and medical treatments, thus, new therapeutic approaches are essential to improve. Curcumin (CUR) is a polyphenol component exhibiting anti-cancer effects and induces apoptosis through different mechanisms especially in human breast cancer. However, there is no study investigating the effects of CUR on FMGTs. AIMS The aim of this study was to determine the anti-proliferative and apoptotic effects of CUR on primary cell lines from FMGT tissue samples of two cases classified as carcinoma-simple, tubular type (grade III). METHODS The cytotoxic effect of CUR was determined by water-soluble tetrazolium salt-1 (WST-1) assay. Annexin V, cell cycle, and acridine orange (AO) analyses were performed to determine the apoptotic effect of CUR. RESULTS Our results showed that CUR had an anti-proliferative and apoptotic effect through induction of apoptosis and cell cycle arrest (G0/G1) on FMGT cells. CONCLUSION Therefore, this is the first study that shows the effects of CUR on FMGTs. However, further molecular studies are required to compare the effects of CUR on different histopathological phenotypes and to determine the further molecular mechanisms including the potential apoptotic and cellular pathways affected by CUR.

Abstract
AIM Testicular torsion is an urgent urological condition. Ischemia-reperfusion (I/R) processes that occur after detorsion as a treatment for torsion are caused by testicular injury. The purpose of our study is investigating the protecting effect of hydrogen sulfide (H2S) on the testicular ischemia reperfusion injury. MATERIALS AND METHODS Thirty-eight Wistar-Albino rats were divided randomly into 6 different groups: Control (6); sham (6); IR-E (6)-2 h of torsion and 4 h of reperfusion; IR-E + H2S (6)-in addition to the IR-E group, 75 μmol/kg of sodium hydrogen sulfide (NaHS) was administered intraperitoneally 30 min before reperfusion; IR-L (7)-2 h of torsion and 24 h of reperfusion; IR-L + H2S (7)-in addition to the IR-L group, 75 μmol/kg NaHS was administered intraperitoneally 30 min before reperfusion. Biochemically, nitric oxide (NO), malondialdehyde (MDA), superoxide dismutase (SOD), reductive glutathione (GSH), and tumor TNF-α levels were measured in the testis. Serum TNF-α levels were also measured. Hematoxylin and eosin (H & E) was used for histopathological staining and microscopic findings were examined. The Johnsen score was performed to assess spermatogenesis activity in the testis. Apoptosis protease activating factor-1 (Apaf-1) and inducible nitric oxide synthase (iNOS) activity were evaluated immunohistochemically as well. Statistical analyses were made by the Chi-squared test and one-way analysis of variance. RESULTS MDA and NO levels were significantly increased in the IR-L group compared with sham and which decreased by the addition of H2S treatment to the IR-L group (p < 0.05) in biochemical evaluation. GSH vs SOD levels were decreased in the IR-L group compared with sham and which increased by the addition of H2S treatment to the IR-L group, but this correlations were not statistically significant (p > 0.05). Tissue and serum TNF-α levels were significantly increased in the IR-E group compared with sham and which decreased by the addition of H2S treatment to the IR-E group. Johnsen score was the lowest in IR-L group (p < 0.05). Apaf-1 and iNOS activity were significantly increased in the IR-L group compared with sham and which decreased by the addition of H2S treatment to the IR-L group (p < 0.05) in immunohistochemical evaluation. CONCLUSIONS First, the authors would like to say that H2S treatment is protective and it is against ischemia reperfusion injury in testicular torsion. The anti-inflammatory, antioxidant, and antiapoptotic properties of H2S caused protective effect as shown in this study.

Abstract
Introduction The aim of this study was to document the data of incarceration in a group of children with inguinal hernia and to investigate whether incarceration could have been prevented. Materials and methods A retrospective study reviewed the records of 3100 children who underwent herniorrhaphy between 1989 and 2007 in one centre, with 113 patients having hernia incarceration. In 16 patients, manual reduction was not attempted because of signs of strangulation, and in the remaining ones, reduction following sedation was not successful. The patients were evaluated with respect to age, postoperative mortality, and morbidity and especially whether he or she had been scheduled for operation in a surgical department. The incidence of incarcerated inguinal hernia and risk factors were analysed. Results Of the 113 patients with incarcerated inguinal hernia, 105 were boys (92.9%), with a male to female ratio of 13:1. The majority of the patients were under one year of age (n=73); and 47 were 0-3 months old. Three laparotomies, 7 small intestinal resection and primary anastomoses, 2 oophorectomy, 7 partial omentectomy and 8 appendectomies were performed. During the 6 months to 18 years follow-up, testicular atrophy was seen in 4 boys. Two babies died. Scrotal oedema, testicular atrophy and mortality rate were significantly higher in incarcerated hernia patients compared with those without incarceration (all with p=0.001). Conclusions Apparently, incarceration may be a preventable problem. Priority should be given to the treatment of inguinal hernias in infants less than 1 year of age, especially those 1-3 months old, as their risk of incarceration is higher.

Abstract
Unconsciously caustic ingestion is one of the most common causes of serious esophageal strictures in children. The aim of this study is to determine the efficiency of polaprezinc in preventing stricture formation after corrosive esophageal burns (CEB); this was the first time it has been used to treat experimental CEB in rats. Twenty-four rats were divided into four groups, three of which received CEB by the instillation of 1 mL of 10% NaOH solution into their isolated esophageal segments for three minutes. Group C (control) was uninjured and untreated. Group B (esophageal burn) received CEB but were left untreated. Groups PT1 and PT2 had CEB and received 100 mg/kg/day and 200 mg/kg/day, respectively, of intraperitoneal polaprezinc treatment (PT) for the first two weeks, then oral PT for another two weeks. We assessed the treatment's efficiency of the treatment after the fourth week by evaluating the stenosis index (SI) and the histopathological damage score, determining tissue hydroxyproline content (HP), and measuring the weight of the rats before and after the experiment. Mean SI was statistically lower in the groups PT1 and PT2 when compared with Group B (p = 0.006, 0.004, respectively). HP levels were highest in Group B, but it was insignificant (P> 0.05). In terms of histopathological damage score, treatment groups demonstrated less collagen deposition, mucosal, and submucosal damage than both Group B (p = 0.01) and Group C (p = 0.02). Group PT1 and Group PT2 (P> 0.05) showed similar results, indicating the treatment's effectiveness was independent of dosage. Outside of Group C, weight gain was detected only in Group PT2, though it was statistically insignificant. In Group PT1, weight loss was lower than in Group B. Polaprezinc, with its antifibrotic, antioxidant, anti-inflammatory, wound-healing and antiapoptotic effects, was efficient in reducing stricture formation by decreasing HP levels and histopathologic damage, preventing stenosis, and weight gain in higher dosages in the treatment group.

Abstract
PurposeTo evaluate the baseline and post-vitrectomy lens densitometry values by a Scheimpflug camera in eyes with epiretinal membrane that were treated with 27-G microincision vitrectomy surgery (MIVS) without tamponade and to compare the results with those in fellow healthy eyes.Patients and methodsProspective case series. The lens densitometry measurements of 24 patients, who underwent 27-G MIVS without any tamponade for the treatment of epiretinal membrane, were taken preoperatively and on the first week, first month, and third month postoperatively with Pentacam HR-Scheimpflug imaging system.ResultsThe mean lens densitometry values at Zone 1 and average lens densitometry values significantly increased in the study eyes on the first month when compared with the preoperative values (P=0.011, P=0.033, respectively). Additionally, there were statistically significant differences regarding the mean lens densitometry values of Zone 1 and Zone 2, and also average lens densitometry values between the preoperative and third month postoperative values (P=0.003, P=0.021, P=0.009, respectively). However, the densitometry values of fellow eyes were similar at preoperatively and all the postoperative follow-up periods (P>0.05 for all).ConclusionsThis study suggests that 27-G MIVS might cause post-surgical lens density changes even in early postoperative months and vitreous may play an important role in protecting the transparency of the lens.

Abstract
BACKGROUND/AIM New compounds for cancer treatment are needed due to persistenly unsatisfactory management of cancer. [PdCl(terpy)](sac)·2H2O] (sac=saccharinate, and terpy=2,2':6',2"-terpyridine) is a compound synthesized for this purpose. We investigated its anti-proliferative and pro-apoptotic effects on Ehrlich Ascites Carcinoma (EAC) in vivo. MATERIALS AND METHODS 42 Balb-c female mice were subcutaneously (s.c.) injected with EAC cells (1st day) and then randomly divided into 5 groups: control (0.9% NaCl), complex (2 mg/kg), complex (3 mg/kg) cisplatin (4 mg/kg) and paclitaxel (12.5 mg/kg). On the 5th and 12th day animals were drug administrated. At 14th day, animals were sacrificed. Expression of cell death and/or cell cycle-related markers (Bcl-2, Bax, active caspase-3, p53, PCNA) and apoptosis were investigated immunohisto-chemically. Survival-related markers (Akt, GSK-3β, IGF-1R, IR, IRS-1, p70S6K, PRAS40) were evaluated by luminex analysis. RESULTS Expression of p53, PCNA, Bcl-2 was found decreased (p<0.001) and that of active caspase-3, Bax, and apoptotic cells was found increased (p<0.001) in all groups. The survival-related markers did not show any statistical difference in complex groups. CONCLUSION The Pd(II)-complex seems to have a strong anticancer activity on EAC by inducing apoptosis via both suppression of proliferation and activation of apoptosis in vivo, similar to the effects of cisplatin and paclitaxel.

Abstract
BACKGROUND/AIM [Pd(sac)(terpy)](sac)•4H2O (sac=saccharinate and terpy=2,2':6',2"-terpyridine) is newly-synthesized palladium(II) (Pd) complex. We investigated the antiproliferative and apoptotic effects of this complex on Ehrlich ascites carcinoma (EAC). MATERIALS AND METHODS EAC cells were administered to 33 Balb/c mice. Mice were divided randomly into four groups: control, cisplatin, Pd(II) complex and paclitaxel. Control group animals received 0.9% NaCl; other groups received treatments cisplatin, Pd(II) complex and paclitaxel on days 7 and 12. At day 14, animals were sacrificed. Expression of active caspase-3, p53 and proliferating cell nuclear antigen (PCNA) was investigated and apoptosis was evaluated by terminal deoxynucleotidyltransferase (TdT)-mediated nick-end labelling (TUNEL) technique. RESULTS Expression of p53 and PCNA were found to be decreased (p<0.0001), cells with active caspase-3 and TUNEL-positive cells were found to be increased (p<0.0001) in all treatment groups. CONCLUSION Like cisplatin and paclitaxel, this Pd(II) complex has a strong anticancer activity against EAC by inducing apoptosis and suppressing proliferation in vivo.

Abstract
BACKGROUND/AIM Compression of the common bile duct by a hydatid cyst located at the head of the pancreas is one of the quite rare causes of obstructive jaundice in childhood. CASE REPORT We report a 9-year-old child with obstructive jaundice caused by compression of the intrapancreatic portion of the bile duct by a hydatid cyst located at the pancreatic head. Furthermore, we considered that this is a reportable case in aspect of childhood development. The patient was treated successfully by surgical procedure and albendazole chemoprophylaxis. The postoperative course was uneventful. CONCLUSION In endemic areas, hydatid cysts should be considered among the differential diagnosis in cystic lesions of any organ including the pancreas.

Abstract
BACKGROUND Obstructive jaundice is one of the most important surgical causes of childhood jaundices. The aim of this study is to investigate effects of ginger (Gingiber officinalis) extracts on liver damage in experimental obstructive jaundice produced by main bile duct ligation. MATERIALS AND METHODS Forty two Wistar-albino rats were randomly allocated into 7 groups (n = 6). Nothing was performed in the control (C) group. Only laparatomy was performed in the sham (Sh) group. The ginger 1 and 2 (G1 and G2) groups received only 100 and 200 mg/kg/day doses of ginger extract for 1 week orally. In study group, common bile duct ligation was done. In treatment 1 and 2 (T1 and T2) groups common bile duct ligation was followed by administration of 100 and 200 mg/kg/day doses of ginger extract for 1 week orally from the third post operative day, respectively. Blood samples and liver were harvested in order to evaluate the serum aspartate aminotransferase (AST), alanine amino transferase (ALT), gama glutamyltransferase (GGT), total bilirubin (bil), superoxide dismutase (SOD), glutathione (GSH), malondialdehyde (MDA) and liver tissue SOD, GSH, MDA levels and liver apoptosis. Results were analyzed by Mann-Whitney U test statistically. RESULTS Ginger administration did not result in any differences of serum or tissue levels of the studied parameters and liver apoptosis between the groups statistically (except AST levels in group T2). Tissue GSH and serum SOD levels were only mildly increased in groups receiving ginger alone. CONCLUSIONS There is no evidence for protective, inhibitive and decreasing effects of ginger extract on liver injury in experimental obstructive jaundice with these findings.

Abstract
BACKGROUND This study aimed to investigate renal arterial resistive index measurements and urine electrolytes before and after enalapril therapy in a rat model of unilateral ureteropelvic obstruction. The transforming growth factor (TGF)-β1 response of the renal tissue was also investigated. MATERIALS AND METHODS 30 Wistar albino rats were randomly allocated into 5 groups (n=6). Group C rats served as controls. Group S rats had only laparotomy. Group E rats were only treated with enalapril. Rats in group UP and group UPE underwent laparotomy to create a left unilateral moderate partial obstruction. 2 weeks after establishing partial ureteropelvic junction obstruction, group UPE rats were treated with enalapril. Urine was collected over 24 h in all groups. Intrarenal arterial resistive index measurements were performed before and 2 weeks after surgery and after enalapril treatment in group UPE, and before and after enalapril treatment in group E. Rats were sacrificed by intracardiac puncture and left kidneys were harvested to evaluate levels of mRNA TGF-β1. RESULTS There was no significant difference in ARI values in group E. In group UPE, the difference between ARI values before and after surgery was statistically significant; the difference between ARI values after surgery and after enalapril treatment was also statistically significant. There was no statistically significant intra-group difference in urine electrolyte levels for UP group or UPE group. There was no difference in renal mRNA TGF-β1 levels. CONCLUSION Enalapril maintained renal blood flow by decreasing the arterial resistive index and maintained renal tubular function by protecting urine concentration and dilution ability in a rat model with unilateral ureteropelvic junction obstruction.

Abstract
INTRODUCTION This study aimed to evaluate the effects of stent placement prior to stricture development following caustic esophageal burn (CEB) in an animal model. The outcomes after stent placement were also compared with those after balloon dilatation and cutting balloon dilatation performed after stricture development. Groups were compared with regard to stricture development and weight loss. MATERIALS AND METHODS 40 rats were divided into 5 groups. CEB was created as described by Gehanno et al. In Group A (control) no CEB was performed and the esophagus was only rinsed with saline. Group B rats underwent CEB with no subsequent treatment. Group C rats underwent CEB followed by balloon dilatation in the 3 (rd) and 4 (th) week. Group D rats underwent CEB followed by cutting balloon dilatation in the 3 (rd) week. Group E rats underwent CEB with subsequent placement of a silicon stent in the same session. The animals were sacrificed in the 6 (th) week, and the stenosis index (SI), collagen deposition, and hydroxyproline (HP) levels were determined in the esophageal segments and statistically compared. RESULTS Although weight loss occurred in Group C and Group B rats (238.87±15.95 g vs. 233.83±19.01 g), weight loss in Group C rats was less marked compared to Group B. Similarly, the SI in Group C was lower compared to that of Group B and the difference was statistically significant. Although there was no difference in weight between the rats in Group C and Group B before the procedure (p=0.318), there was statistically significant difference thereafter (p=0.002). The SI of Group D was also lower compared with that of Group B, and the difference was statistically significant. Weight gain in Group E rats was similar to that noted in Group A rats and was higher compared to Group B; this difference was statistically significant. The SI for Group E was lower compared to that of Group B. CONCLUSION Stenting performed at the time of corrosive injury and cutting balloon dilatation performed after stricture formation had a positive effect with regard to SI and weight gain in an animal model.

Abstract
AIM McKusick-Kaufman syndrome (MKKS) is a rare autosomal recessive disorder. Less than one hundred cases have been reported in the English literature to date. We report three different aged children with a large hydrometrocolpos and postaxial polydactyl. PATIENTS AND RESULTS These children had various degrees of associated renal disorders. Bardet Biedl syndrome (BBS) is characterized by retinal dystrophy or retinitis pigmentosa, postaxial polydactyl, obesity, nephropathy, mental disturbances or mental retardation. Typically MKKS is diagnosed in young children especially in neonates whereas the diagnosis of BBS is delayed until the teenage years. CONCLUSION All MKKS cases should be re-evaluated for Retinitis pigmentosa, other signs of BBS and for disorders that may worsen with time (Ref. 12).

Abstract
BACKGROUND The recommended approach to hydrocele repair in children is inguinal. Recently, a transscrotal approach has been recommended for hydroceles in children. This report describes our experience with hydrocele with omentum incarceration. METHODS This retrospective study reviewed the records of ten children who underwent inguinal hydrocele repair with omentum incarceration in our clinic. RESULTS The mean age of the patients was 4.5 years (range 1.5-16). Hydroceles were located on the right side in all patients. Scrotal erythema, inguinal pain, signs of intestinal obstruction and hernia sac were not determined. Hydrocele repairs were made by inguinal approach in all patients. The procesus vaginalis was rougher than normal and noted as the hernia sac. Thus, the hernia sacs were opened and omental incarceration was defined in all cases. Omentum protruded into the abdomen in all cases. A high ligation was performed and the distal parts of the sacs were fenestrated. CONCLUSIONS In the light of our experience, a scrotal approach to hydrocele repair in children would be difficult in cases of incarceration with hernia. Omental incarceration may cause hydrocele, and this hydrocele can be confused with normal hydrocele. Therefore, we would continue to recommend an inguinal approach for childhood hydroceles.

Abstract
INTRODUCTION The aim of this study was to determine the normal position of the umbilicus so as to offer a guide to improve cosmetic results after the repair of congenital abdominal wall defects. MATERIALS AND METHODS The position of the umbilical center was determined in 187 neonates with respect to the xiphoid process, the center of the umbilicus and the pubis. The distance between the xiphoid process and the center of the umbilicus (XU), between the pubis and the center of the umbilicus (PU) and from the xiphoid process to the pubis (XP) were measured while the babies lay in a supine position. The PU:XU ratio was calculated based on these measurements. RESULTS Mean XP was 11.93±1.40 cm, mean XU was 7.41±1.08 cm and mean PU was 4.52±0.70 (mean±SD). The PU:XU ratio was calculated as 0.61±0.12 (ratio±SD). CONCLUSION We suggest that the PU:XU ratio should be 0.61 offering an ideal localization in umbilical reconstruction.

Abstract
Cefoperazone is a parenteral third generation cephalosporin which is active against many Gram positive and Gram negative organisms. Cefaperazone, like other cephalosporins which contain methyltiotetrazole side chain, can cause hypoprotrombinaemia and bleeding problems. Here we report a nine-year old child with Meckel's diverticulum who had cefoperazone induced massive gastrointestinal bleeding on the fifth day following the operation.

Abstract
AIM To describe the use of tissue glue to close scleral and conjunctival wounds, and to compare the clinical outcomes using tissue glue and vicryl suture for closing these areas in conventional 20-gauge (G) vitrectomy. METHODS Thirty eyes of 30 patients were included in this study. The indications for vitreoretinal surgery were diabetic vitreous haemorrhage with severe vitreoretinal traction in 10 eyes, retinal detachment and proliferative vitreoretinopathy in 14 eyes, and vitreous opacity in 6 eyes. Tissue glue (Tisseel, Baxter AG Industries, Vienna, Austria) was used to attach scleral and conjunctival wounds in 15 eyes and vicryl sutures in 15 eyes. The patients were allotted into two subgroups as tissue glue group (TG) and vicryl suture group (VG). The sclerotomy sites were evaluated with ultrasound biomicroscopy (UBM) postoperatively in TG. Follow-up period was 2 months. The groups were statistically compared for ocular signs and symptoms by Mann-Whitney U-test. RESULTS No scleral wound leakage and conjunctival reattachment were observed at the end of the surgical procedure and during the follow-up period. No adverse effects were seen in TG. Abnormal fibrous ingrowth was not detected at the sclerotomy sites by means of UBM in TG. Patient comfort was significantly higher in TG than VG (P<0.05). CONCLUSIONS Tissue glue has no adverse effects on ocular tissue and can be used as a substitute for suture materials, and the use of tissue glue decreases patient symptoms during the postoperative period after 20-G vitrectomy. Tissue glue can enable to perform sutureless surgery in the conventional 20-G vitrectomy.

Abstract
Congenital neck masses in children and their embryologic and clinical features. Neck masses of congenital origin can be diagnostic and therapeutic challenges for internists, paediatricians and surgeons. Treatment modalities of congenital neck masses are different depending on their nature, symptoms and location. Differential diagnosis includes a variety of diseases that can cause cervical masses such as infectious and neoplastic neck tumours. Our objective is to review the embryologic and clinical features of some of the most common congenital neck masses such as the haemangioma, branchial cleft anomalies, thyroglossal duct cyst, ectopic thyroid, congenital midline cervical cleft, congenital cervical teratoma, lymphangioma, cervical thymic cyst, dermoid cyst and congenital muscular torticollis.

Abstract
The aim of this study was to investigate Bovine Spongiform Encephalopathy (BSE) in Turkish cattle in the Marmara region which borders the European Union (EU). For this, cattle brought to abattoirs in Istanbul were analysed. The high risk group were selected and therefore 384 cattle above 2 years old were included in the study. They were primarily examined for the presence of any clinical signs of nervous system and also other clinical disorders. The whole brains were taken and analysed for the presence of vacuolar degeneration and prion protein by PLATELIA BSE test kit. Only 5 cattle were found to be nervous and showed aggressive behaviour. There were no cattle showing incoordination or other neurological disorders. Cysts were observed in 3 brains. Histopathologically, no vacuolar degeneration indicative of BSE was found in any cattle examined. However, in 8 brains, few vacuoles were observed in neurons in sections taken from the brain, cerebellum, medulla oblongata and medulla spinalis. Slight mononuclear cell infiltration in 9 brain, intensed mononuclear cell infiltration in 1 brain, haemorrhages in 5 brains and gliosis in 11 brains were also found. No infective prion was detected by ELISA in samples taken from 384 cattle brain.

Abstract
Summary Inflammatory cytokines have been demonstrated to play an important role in the induction and severity of acute pancreatitis (AP) in the recent studies. The aim of this study was to investigate the effects of curcumin on inflammatory cytokines, such as tumour necrosis factor (TNF)-alpha and interleukin (IL)-6 in the late phase of AP. The study was conducted on 40 male Wistar Albino rats. The animals were divided randomly into four equal groups. AP was induced by the infusion of 3% sodium taurocholate into the biliopancreatic duct (in groups I and II). Starting on day 20 prior to the induction of AP, rats in group I received daily dose of 100 mg/kg of curcumin, dissolved in 9% ethanol via an intragastric tube. The same procedure was repeated for 6 days following the onset of AP. Group III was infused only on saline solution. Group IV (curcumin control group) received 9% ethanol via an intragastric tube, during the experimental period (totally 26 days). All the animals were sacrificed on day 6 after the collection of blood samples and serum TNF-alpha and IL-6 levels were determined. Tissue samples were taken from pancreas, mesenteric lymph nodes, liver, lungs, spleen and the kidneys for histopathological evaluation. Serum TNF-alpha and IL-6 levels in the group, which received curcumin (group I), were determined to be significantly lower than those of the untreated group (group II) (P<0.05). No statistically significant difference was detected in terms of total histopathological scores in the treatment group versus untreated group. Curcumin has been shown to markedly reduce serum TNF-alpha and IL-6 levels in the late phase of AP, but failed in the prevention of tissue injury.

Abstract
Mechanical bowel cleansing is considered to be necessary prior to colorectal surgery, some radiological or endoscopic procedures, and for fecal disimpaction. Traditional bowel cleansing (TBC) with cathartics and enemas is a method of mechanical bowel cleansing for patients who have restrictive factors for whole-bowel irrigation (WBI), such as excessive fecal impaction, cardiac, hepatic or renal disorders. In this experimental study, TBC with hyperosmolar agents was evaluated in terms of their effects on colonic flora and bacterial translocation (BT). Sprague-Dawley rats were divided into 6 groups. The animals, except controls, were not fed for 72 h but received tap water ad libitum. During this period, lactulose, lactitol, sodium phosphate (NaP), polyethylene glycol 3350 (PEG3350) and physiological saline gavages were administered to the rats in groups 1-5, respectively, once a day. All animals except controls (group 6) received enemas with 15 ml of warm saline twice a day. The cecum, mesenteric lymph nodes (MLNs) and portal vein blood were sampled for microbiological and histopathological analysis. The highest level of coliform bacterial overgrowth and BT to MLNs were observed in the lactulose group, although the others, except the saline and control groups, also caused some degree of BT. Portal vein cultures were negative for all groups. Histopathological damage was not associated with cecal bacterial count and BT. As a result of this study, PEG3350 seems to be safer and more effective than lactulose, lactitol and NaP during TBC.

Abstract
The rare hungry bone syndrome was encountered in a 15-year-old child after the removal of a parathyroid adenoma. Contrary to the hypocalcemias caused by the removal of all parathyroid glands or transient ischemia after parathyroid surgery, in which the serum inorganic phosphorus level is usually normal, both serum calcium and inorganic phosphorus levels are decreased in hungry bone syndrome in the early postoperative period. Vigorous calcium supplementation and vitamin D are required for prolonged periods.
