[Duodenum perforations in children: case series].

To analyse patients those admitted to our clinic due to perforation in duodenum. Fourteen patients those have been admitted to our center with perforation in duodenum between 1990 - 2014 analysed retrospectively. Ten patients (8M, 6F) those have been admitted to our clinic between 1990 - 2014 have a mean age of 6.

Comparison of the efficiencies of esophageal manometry, vector volume analysis and esophagus pH monitoring in the diagnosis of gastroesophageal reflux.

Aim: In this study, we aimed to compare the superiorities of esophageal manometry, vector volume analysis and 24-hour pH meter studies in showing gastroesophageal reflux disease.

Material And Methods: The files of the patients who presented to pediatric surgery and pediatric gastroenterology outpatient clinics of our hospital with suspicious gastroesophageal reflux disease between 2011 and 2012 and who were investigated were examined and 21 patients whose investigations had been completed were included in the study. The patients were evaluated by treatment method and were divided into three groups as Group 1 who were followed up with medical treatment, Group 2 in whom surgical intervention was performed and Group 3 who were not treated.

Types of HLA in the bladder transitional cell carcinoma (TCC).

HLA plays a complementary role in the interaction between tumor and body immunology. The aim of this study was to determine the existence of the association between the HLA system and transitional cell carcinoma (TCC). Using standard micro-lymphocytotoxic method of Terasaki, HLA-A, B, DR and DQ antigen types of 30 patients with TCC of the bladder were compared with the control group (30 healthy people).

The relationship between human leukocyte antigens (HLA) and renal cell carcinoma.

Etiologies of Renal Cell Carcinoma (RCC) are not clear despite of the fact that many risk factors have been suggested. Especially in high stages RCC can affect the immune system in various ways. Human Leukocyte Antigens (HLA) may play a complementary role in the activation between the tumor and immunity.

Segmental dilatation of the ileum accompanying hypoproteinemia.

Purpose: Segmental intestinal dilatation (SID) is a rare pathologic finding, which causes intestinal obstruction in newborn period and gastrointestinal bleeding, anemia, abdominal pain, malabsorption, and growth failure in older children. We present a case of SID causing hypoproteinemia.

Patient: A 10-year-old girl presented with recurrent abdominal distension since she was 8.

Management of esophageal perforation secondary to caustic esophageal injury in children.

Purpose: To review our management of esophageal perforation in children with caustic esophageal injury.

Method: We reviewed the medical records of 22 children treated for esophageal perforations that occurred secondary to caustic esophageal injury.

Results: There were 18 boys and 4 girls (mean age, 5 years; range, 2-12 years).

Analysis of HLA antigens in Turkish sarcoidosis patients.

Background: Sarcoidosis is a systemic granulomatous disorder associated with high CD4+cell activity, without any detectable pathogen. Clustering in families occurs, and the existence of a genetic predisposition to sarcoidosis is widely accepted. There are differences among different ethnic groups.

Extrathoracic liver hamartoma.

Mesenchymal hamartoma is a benign tumor of the liver that often presents because of a palpable abdominal mass or respiratory distress. An unusual protrusion of this tumor through the chest wall of a neonate with Poland's syndrome is reported.

Neonatal gastric perforation: review of 23 years' experience.

Purpose: To review our experience of treating 13 neonates with gastric perforation (GP) over the past 23 years.

Methods: The records of all 13 patients were reviewed, noting gender, weight, gestational age, age at admission, associated anomalies, site of perforation, type of operation, and clinical outcome.

Results: There were 11 boys and 2 girls, with a mean body weight of 2 375 g, including 4 (45%) preterm infants.

Intestinal rotation anomalies in childhood: review of 22 years' experience.

Purpose: We review our experience of treating intestinal rotation anomalies in infants and children in the 22-year period between 1978 and 2000.

Methods: The type of operation performed, postoperative complications, and mortality were compared in three age groups. Group 1 consisted of neonates <1 month old, Group 2 consisted of infants aged <1 year old, and Group 3 consisted of children aged >1 year old.

Pyloric atresia: 15-year review from a single institution.

Background: Pyloric atresia (PA) is a rare pathology. Calder presented the first pyloric atresia case in 1749 and Touroff, Sussman, Meltz, and their colleagues presented the first successful operation in 1940. PA has 3 types of anatomic variations: (1) type A, pyloric membrane or web; (2) type B, the pyloric channel is a solid cord; and (3) type C, in which there is a gap between the stomach and duodenum.

An infrequent cause of misdiagnosis in esophageal atresia.

Inability to pass an oral tube in infants with esophageal atresia often leads to the diagnosis of this anomaly. This report describes an infant with a delay in diagnosis resulting from initial passage of an oral tube through a distal tracheoesophageal fistula into the stomach.

Tracheostomy in childhood: 20 years experience from a pediatric surgery clinic.

Background: There is a limited indication for tracheostomy procedures in pediatric surgery. It is rarely applied to the pediatric patient because they can be kept intubated for a longer duration compared with adults. Problems and complications can occur after tracheostomy, even during the childhood period.

An association between mesial temporal lobe epilepsy with hippocampal sclerosis and human leukocyte antigens.

Purpose: Mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS) is one of the medically intractable epilepsies that may be remediable with surgery. Although the pathogenesis of HS still remains obscure, genetics may play a role as a predisposing factor, with the genetically controlled immune system as one of its aspects. Our aim in this study was to investigate whether there is any association between human leukocyte antigens (HLAs) that are related to chromosome 6 and this specific type of epilepsy.
