ATPase inhibition by omeprazole reveals role of heat shock proteins on testicular torsion.

Testicular torsion leads ischaemic injury and generates reactive oxygen species. Reactive oxygen species triggers lipid peroxidation, protein degradation and DNA damage. These biochemical processes trigger tissue damage. Heat shock proteins (HSPs) are important in spermatogenesis, and this work elucidates role of HSPs at the testicular torsion-detorsion process. A proton-pump inhibitor, omeprazole, tested to reveal the drug's curative effect since HSP functions through ATP hydrolysis. Thirty-two male Wistar Albino rats were divided into four groups: sham, control, omeprazole and serum physiologic groups. Right testis was torsed, while left ones remained untorsed. Protein peroxidation, DNA damage and lipid hydroperoxide levels as well as HSP expression were measured. Further, the effects were visualised with histopathologic imaging. HSP expression increases at the torsed right testis compared to the contralateral testis. Although HSP70 and HSP90 help antioxidant enzymes to keep their native structure, their anti-apoptotic properties accelerate the tissue damage. Omeprazole a proton-pump inhibitor employed to impair electron transfer chain and to inhibit HSP ATPase function. Omeprazole effectively inhibits HSPs and alleviates lipid peroxidation and DNA damage levels both at molecular and at tissue level, and the drug has profound curative effect on testicular torsion recovery.

Megacystis Microcolon Intestinal Hypoperistalsis Syndrome in Which a Different De Novo Actg2 Gene Mutation was Detected: A Case Report.

INTRODUCTION: Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is characterized by bladder distension without urinary tract obstruction, decreased or absent intestinal peristalsis and microcolon. Although the definitive cause remains unknown, changes in the ACTG2 gene are thought to be responsible for the intestinal and bladder hypoperistalsis. CASE REPORT: This female newborn with MMIHS had a c.532C>A /p.Arg178Ser heterozygous de novo mutation detected in the ACTG2 gene. Normal immature ganglion cells, normal calretinin punctate positivity, maintence of smooth muscle actin immunoreactivity, and decreased numbers of interstitial cells of Cajal(ICCs) were detected. CONCLUSION: This previously unreported c.532C>A /p.Arg178Ser heterozygous de novo mutation in the ACTG2 gene may lead to a severe form of MMIHS.

Splenic rupture presenting with marked scrotal ecchymosis in a 2-day-old newborn.

Splenic rupture is a rare and severe condition in neonates. The signs and symptoms are vague and non-specific and are often not recognised before the onset of hypovolaemic shock or death. A 2-day-old infant presented with scrotal ecchymosis, and ultrasonography detected haemorrhage in the scrotal, right inguinal and adrenal regions. Computed tomography demonstrated a peri-splenic haematoma. Haemoglobin (Hb) was 2.79 g/dL and, despite repeated transfusions, the Hb level could not be sustained. Exploratory laparotomy detected a large haematoma in the splenic region, and, because of the uncontrolled haemorrhage, splenectomy was required.

[Our childhood cases with intussusception and pneumatic reduction]. / Cocukluk çagi invajinasyon olgularlmlz ve pnömatik redüksiyon.

BACKGROUND: Intussusception is defined as telescopic insertion of the terminal ileum in to the colon after the cecum and colon. The aim of this study was to present our experience in pneumatic reduction of intussusception. METHODS: In our study, 118 intussusception cases treated between 1996 and 2008 were analyzed. Age, gender, admission time, diagnostic/treatment methods, types of intussusception including leading point, and postoperative complications were evaluated. RESULTS: Of these patients, 76 (64%) were male and 42 (36%) were female. Mean age was 25 +/- 34 months (3-180 months). The most common clinical presentations were vomiting, abdominal pain/irritable crying and bloody stools. Intussusceptions were ileocolic in 109 (92.3%) patients, ileoileal in 7 (6%) patients, and colocolic in 2 (1.7%) patients. No mortality was noted. Fifty-three patients (45%) were treated by nonoperative reduction whereas the remainder were treated surgically. Among 65 patients operated, 13 leading points were detected. Pneumatic reduction success rate was 86%. Age significantly reduced the pneumatic reduction success rate; however, the duration between the beginning of symptoms and hospital admission and bloody stool were not effective. CONCLUSION: Intussusception can be treated by non-operative methods when diagnosed early. Our results suggest that pneumatic reduction of intussusception in the pediatric population should be considered as a first choice.

[An interesting journey of a grass inflorescence from broncho to dorsum: case report]. / Bir pisipisi otunun bronslardan sirta ilginç yolculugu: olgu sunumu.

A 15-years-old male was presented with hyperemic and painful right flank mass. His medical history was consisted of a treatment for pneumonia and hemoptysis in the other hospital five months ago. Diagnostic X-rays was showed consolidation in the posterobasal segment of right pulmonary lobe and abscess in the paravertebral muscle extending from L4-5 level. The patient was discharged after antibiotic treatment. At the second hospitalization, a grass inflorescence was discharged from the fistula. When the patient was reevaluated his history was consisted of the aspiration of a grass inflorescence eight months ago. To our knowledge, this patient represents the first case of penetration by a grass inflorescence migrated out of the lumbar region.

A Fifteen-Year Analysis of Rare Isolated Fallopian Tube Torsions in Adolescent Children: A Case Series.

Isolated tubal torsions presenting to the emergency department are a very rare cause of pediatric acute abdominal pain. Since making the diagnosis early is of importance in terms of affecting tubal damage and fertility, we aimed to evaluate cases of isolated tubal torsions in light of the literature. This study included 10 patients under 18 years of age who presented to the emergency department with abdominal pain between January 2003 and December 2018. The mean age was 14.5 ± 1.43 years (range: 12-17 years). The demographic characteristics, surgical findings and techniques, and concomitant pathology results of these patients were retrospectively evaluated. The reason for presenting to the emergency department for the 10 patients included in the study was abdominal pain. The mean duration of hospital admission with pain was 4.97 days. The onset of pain was less than 24 h in seven patients (70%) and more than 24 h in three patients (30%). Of the patients, nine (90%) had tenderness in the lower abdominal quadrant, five (5%) had defense, and three (30%) had rebound. Nausea, vomiting and leukocytosis were present in 50% of the cases. Right and left tubal involvement of the cases was equal. Seven (70%) of the isolated tubal torsions were accompanied by paraovarian cysts. Eight patients (80%) underwent open surgery and two (20%) underwent laparoscopic intervention. Detorsion was performed on five (50%) patients and salpingectomy was performed on five (50%) patients. Isolated tubal torsion should be considered in children presenting with acute abdominal pain in early adolescence. Early diagnosis is important for the preservation of fertility.

Can Fetuin-A, CRP, and WBC Levels Be Predictive Values in the Diagnosis of Acute Appendicitis in Children with Abdominal Pain?

Background: Acute appendicitis (AA) is the most common cause of emergency surgery. Therefore, perforation is common. Early diagnosis and new markers are needed. The aim of this study was to investigate the effects of plasma Fetuin-A (FA) levels in patients with an acute abdomen (AB). Material and Method: This prospective study included 107 patients younger than 16 years of age who were admitted to the emergency department for abdominal pain between January and December 2018. The patients who presented abdominal pain were divided into two groups as AA and other causes (OC) of AB. Patients with acute appendicitis; intraperitoneal, retrocolic/retrocecal, and appendicitis were divided into three groups. Additionally, the AA group was divided into two groups as perforated appendicitis and non-perforated appendicitis. Serum FA levels of the patients were evaluated in the emergency department. Results: In the AA group, C-reactive protein (CRP) and white blood cell (WBC) levels were higher, and FA levels were significantly lower than in the AB group. Intraperitoneal localization was 95.2% and perforation was frequent. When significant values in the univariate regression analysis for acute abdomen and perforation were compared in the multivariate regression analysis, CRP, WBC, and FA levels were found to be prognostic. Furthermore, decreased FA levels were associated with AA, while too greatly decreased FA levels were associated with the risk of perforation. Conclusion: Current diagnosis can be made by history, physical examination, laboratory, and imaging methods in appendicitis cases. While trying to diagnose AA in children, the FA, CRP, and WBC levels may be predictive values to identify risk factors.

Alterations in spontaneous contractions of rat ileum and jejunum after peritonitis.

The aim of this study was to investigate the effects of peritonitis on spontaneous contractions of ileum and jejunum smooth muscles isolated from rats. Peritonitis was induced by cecal ligation and puncture in 8 rats. Another group of 8 rats underwent a sham operation and acted as controls. Twenty-four hours after the operation, the rats were killed, and their ileum and jejunum smooth muscles were excised and placed in circular muscle direction in a 10 ml organ bath. Changes in the amplitude and frequency of spontaneous contractions were analyzed before and after the addition of different antagonists. Peritonitis induced the decrease in the amplitude and frequency of spontaneous contractions in ileum and jejunum smooth muscles. In control groups, both ileum and jejunum, the amplitude and frequency of spontaneous contractions were significantly elevated in the presence of N(G)-nitro-L-arginine (L-NNA) and indomethacin. In peritonitis groups, both ileum and jejunum, the amplitude and frequency of spontaneous contractions were significantly enhanced in the presence of L-NNA, aminoguanidine, indomethacin and celecoxib compared to control values. In conclusion, peritonitis induces the decrease in the amplitude and frequency of spontaneous contractions of ileum and jejunum that can be attributed to the rise of nitric oxide synthase and cyclooxygenase isoforms levels.

[A case of endobronchial aspergilloma]. / Endobronsiyal aspergilloma olgusu.

Infections caused by Aspergillus spp. in immunocompromised or atopic patients may present as invasive aspergillosis, allergic bronchopulmonary aspergillosis and aspergilloma. In this report a 69 years old female patient admitted to the hospital with the complaints of intermittent cough and sputum and diagnosed as endonbronchial aspergilloma, has been presented. The patient was not immunocompromised, however she has bronchial asthma for 10 years and the disease is now under control. The chest radiography and computed tomography revealed lung infiltration with undefined borders, and bronchoscopy demonstrated the presence of a mass at left lower lobe. In the pathologic examination of biopsy specimen with the use of methenamine silver and PAS methods, hyphae formations concordant with Aspergillus were detected. The direct microscopic examinations of biopsy material and sputum obtained after bronchoscopy, have also revealed the presence of hyphae. A. fumigatus was isolated from the cultures of biopsy material and sputum specimen. The patient was diagnosed as endonbronchial aspergilloma, however the follow-up was failed since she has not accepted medical or surgical treatment. In conclusion, aspergilloma should be considered in the differential diagnosis of mass lesions in the endobronchial area.

Genetic diversity and major spoligotype families of drug-resistant Mycobacterium tuberculosis clinical isolates from different regions of Turkey.

To highlight the transmission rate and major phylogenetic clades of drug-resistant Mycobacterium tuberculosis isolates, a total of 200 drug-resistant strains isolated in four different regions of Turkey (Marmara n=81; Mediterranean n=39; Aegean n=42; East Anatolia n=38), were typed by spoligotyping and IS6110-restriction fragment length polymorphism (RFLP). The major spoligotyping-defined shared-types (STs) and corresponding lineages were, ST 41 (22.5%, LAM7-TUR), ST53 (19.5%, ill-defined T super-family), ST 50 (6.5%, Haarlem 3), ST 1261 (4.5%, LAM7-TUR), ST 47 (3.5%, Haarlem 1), as well as two STs that belonged to undefined clades (ST 284, 3%, and ST 2067, 2.5%). The global distribution of major M. tuberculosis lineages among drug-resistant strains was as follows: T super-family (29%), Latin-American & Mediterranean (33.5%), Haarlem (14%), and the S lineage (3%). A high number of strains (n=29, 14.5%) showed patterns that did not fall within major clades described so far. A combination of spoligotyping and IS6110-RFLP fingerprinting methods resulted in a final clustering rate of 38.5% and a recent transmission rate of 25.5%. Our results underline the highly diverse nature of drug-resistant tuberculosis in our study population, as well as its ongoing transmission with lineages that are specific to these regions, the most predominant being the LAM7-TUR lineage which shows an enhanced phylogeographical specificity for Turkey.

Does Helicobacter pylori infection play a role in lung cancer?

BACKGROUND: Helicobacter pylori infection is a world-wide common disease and leads to many gastrointestinal and respiratory illnesses. It is suggested that one of these respiratory illnesses is lung cancer. METHODS: Forty-three patients with non-small cell lung cancer and 28 control subjects have been included to this study. H. pylori status of the patients and controls was determined by immunoblot for the detection of IgG (RIDA Blot Helicobacter). All subjects were examined to evaluate the presence of VacA and CagA gene. RESULTS: Seropositivity of anti H. pylori IgG was significantly higher in cancer patients than in control groups, 40 (93%) and 12 (42%), respectively (P<0.01). Although both VacA and CagA seropositivity was high in lung cancer patients, only VacA positivity was statistically significant when compared with control subjects, 35 (81%) and 11 (42%), respectively (P<0.05). CONCLUSION: H. pylori infection may be associated with development of lung cancer.

Amyand's hernia in the children: a single center experience.

BACKGROUND: The presence of a vermiform appendix in an inguinal hernial sac is termed Amyand's hernia. It may present as a tender inguinal or inguinoscrotal swelling, and it is often misdiagnosed as an incarcerated or strangulated hernia. METHODS: Between 1998 and 2006, we have managed 564 patients with acute appendicitis, 1,090 patients with inguinal hernia, 33 patients with incarcerated inguinal hernia, and 12 patients with Amyand's hernia on our pediatric surgery service. A retrospective analysis of clinical data of these patients with Amyand's hernia was performed. RESULTS: All patients with Amyand's hernia were boys with a median age of 40 days (range, 15 days-14 months). One patient's condition was diagnosed pre-operatively. All of them, therefore, underwent emergency operation with a presumptive diagnosis of either incarcerated or strangulated inguinal hernia. Operative findings included 2 normal appendices, 6 inflamed appendices, and 4 appendices with external signs of serosal inflamation of uncertain significaince in the inguinal hernial sac. Two patients with a normal appendix had hernia repair without an appendectomy. The other 10 patients with an abnormal appendix underwent an emergency open appendectomy with repair of the inguinal hernia. None of the patients developed recurrent hernia. The median postoperative follow-up period was 2.5 years. CONCLUSION: In pediatric patients with Amyand's hernia, the inflammatory status of the appendix can be used to determine the type of hernia repair and the operative approach. Incidental appendectomy in the case of a normal appendix is not favored by us. Treatment includes appendectomy (via the hernia sac) and hernia repair in children with an inflamed appendix.
