Effect of Oltipraz on urethral healing: An experimental study.

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.

The anti-proliferative and apoptotic effects of curcumin on feline mammary gland tumor cells in vitro.

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.

Protective effect of hydrogen sulfide on experimental testicular ischemia reperfusion in rats.

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.

The quantitative assessment of alterations in lens transparency after transconjunctival 27-gauge microincision vitrectomy surgery.

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.

Effect of polaprezinc on experimental corrosive esophageal burns in rats.

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.

Measurement of C-reactive protein and prostaglandin F2α metabolite concentrations in differentiation of canine pyometra and cystic endometrial hyperplasia/mucometra.

Canine pyometra is a dioestrus period disease in which systemic inflammatory response syndrome (SIRS) is a common outcome due to the response of the body to the bacterial infection. The purpose of this study was i) to differentiate canine pyometra and cystic endometrial hyperplasia (CEH)/mucometra by measuring serum C-reactive protein (CRP) and prostaglandin F2α metabolite (PGFM) concentrations in blood and ii) to compare serum concentrations of CRP and PGFM in bitches with a pathological uterus (pyometra or CEH/mucometra) to concentrations in bitches with a healthy uterus. Mean CRP concentrations were found significantly higher (p < 0.001) in dogs with pyometra compared to those with CEH/mucometra or healthy uterus. However, no statistical difference could be detected between the groups for mean PGFM concentrations. Mean white blood cell count (WBC), alkaline phosphatase (ALP) and total protein concentrations were found significantly higher (p < 0.001) in dogs with pyometra. Escherichia coli was the most frequently isolated microorganism from dogs with pyometra (64.3%). Edwardsiella spp. was detected in a single case of pyometra for the first time. In conclusion, our results demonstrate that serum CRP concentrations were increased in dogs with pyometra and thus we conclude that serum CRP concentration but not PGFM might be useful as a marker to differentiate a case of CEH/mucometra from pyometra in female dogs. To the authors' knowledge, this is the first report in which Edwardsiella spp. has been isolated in the canine uterus.

Two isolated giant gastric duplication cysts in thorax in a newborn.

We report a case of a newborn with severe respiratory distress since birth with two giant intrathoracic and separate eneteric duplication cysts in right hemithorax. On day 19, the intrathoracic cysts were removed, and the baby was discharged on his 22nd day of life. Histologic findings confirmed the diagnosis of a gastric duplication cyst. This report is the first case of two isolated, separated and giant right intrathoracic gastric duplication cysts in literature. The diagnostic values of radiological evaluation and surgical and pathological management for precise diagnosis are discussed.

Effect of ginger extract on liver damage in experimental obstructive jaundice produced by main bile duct ligation.

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.

Obstructive jaundice resulted from hydatid cyst of pancreatic head.

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.

Twenty-Four Genes are Upregulated in Patients with Hypospadias.

Hypospadias is a congenital hypoplasia of the penis, with displacement of the urethral opening along the ventral surface, and has been reported to be one of the most common congenital anomalies, occurring in approximately 1:250 to 1:300 live births. As hypospadias is reported to be an easily diagnosed malformation at the crossroads of genetics and environment, it is important to study the genetic component in order to elucidate its etiology. In this study, the gene expression profiles both in human hypospadias tissues and normal penile tissues were studied by Human Gene Expression Array. Twenty-four genes were found to be upregulated. Among these, ATF3 and CYR61 have been reported previously. Other genes that have not been previously reported were also found to be upregulated: BTG2, CD69, CD9, DUSP1, EGR1, EIF4A1, FOS, FOSB, HBEGF, HNRNPUL1, IER2, JUN, JUNB, KLF2, NR4A1, NR4A2, PTGS2, RGS1, RTN4, SLC25A25, SOCS3 and ZFP36 (p <0.05). Further studies including genome-wide association studies (GWAS) with expression studies in a large patient group will help us for identifiying the candidate gene(s) in the etiology of hypospadias.

The effect of enalapril on renal resistive index, urine electrolyte levels and TGF-ß1 levels of kidney tissues in rats with unilateral partial ureteropelvic junction obstruction.

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)-ß1 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-ß1. 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-ß1 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.

Our experience with McKusick-Kaufman syndrome patients.

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).

Effect of stent placement, balloon or cutting balloon dilatation on stricture formation after caustic esophageal burn in rats.

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.

Immunocytochemical detection of Rhodococcus equi in tracheal washes of foals.

The aim of the present study was to develop an immunocytochemical procedure for the early detection and demonstration of Rhodococcus equi in smears of tracheal aspirates taken from live foals in field conditions. Tracheal wash samples were collected from thoroughbred foals, aged 1-5 months and located in studs around Bursa and Istanbul, Turkey. Some foals were suspected of having R. equi infection on the basis of clinical examination (n=56) and others were unaffected control animals (n=54). Serum samples were also collected from each foal for testing for the presence of R. equi-specific antibody by enzyme linked immunosorbent assay (ELISA). Thirty-six of the control foals (66.7%) and 37 of the affected foals (66.1%) were seropositive for R. equi. Immunocytochemical labelling was detected in the smears from 73.2% of the affected foals and 70.4% of the control foals. For both ELISA and immunocytochemistry (ICC), there was no significant difference between the affected and control foals (P>0.05) and there was no significant difference between the two test modalities (P>0.05). ICC may therefore have similar diagnostic utility when compared with ELISA. There is no clear relationship between clinical signs and ELISA or ICC positivity.

Negative appendectomy experience in children.

BACKGROUND: The aim of this study was to discuss the findings of our patients who had negative appendectomy. PATIENTS AND METHODS: Hospital records of negative appendectomy for abdominal pain patients were evaluated retrospectively. RESULTS: Negative exploration for acute appendicitis (AP) was done in 149 patients. The most frequent complaints were abdominal pain, vomiting and fever. The commonly established diagnoses after negative exploration were gastroenteritis and urinary infections. However, the frequent pathologies observed during the operation were mesenteric lymphadenitis and Meckel's diverticulum. All patients with systemic disease such as Henoch-Schonlein's purpura operated for AP had it diagnosed during the postoperative course. Interestingly, two different types of worms were found in the lumen of the appendices. CONCLUSION: Despite new techniques, 100% correct diagnosis of AP is still a challenging problem. Furthermore, appendicitis is a deadly disease if not treated properly. Therefore, it is best to perform exploration without undue delay in cases with suspicious AP.

Omental incarceration may cause hydrocele and this hydrocele confused simple or scrotal hydrocele.

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.

Where should the normal position of the umbilicus be in the neonate?

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.

Resection of blind ending bifid ureter in a patient with grade V vesicoureteric reflux.

Blind-ending bifid ureter is an extremely rare congenital anomaly. The authors report on a 13-year-old boy who presented with a previous diagnosis of right duplicated ureter and who had undergone a bilateral ureteroneocystostomy for vesicoureteral reflux in another clinic. The revision showed right blind-ending bifid ureter. The embryology, clinic and treatment of this anomaly is discussed.
