Local effects of epidermal growth factor on the wound healing in esophageal anastomosis: An experimental study.

Objective: In this study with the experimental model of primary repair of esophageal atresia(EA), we investigated the effects of the epidermal growth factor(EGF) on wound healing in the anastomosis of EA.

Materials And Methods: Forty rabbits that were performed a resection of a 1-cm segment of the cervical esophagus followed by the end-to-end anastomosis were divided into four groups. Group I (7-day group) and III (21-day group), the control groups, had no EGF applied to the anastomosis.

Coexistence of glomangioma and yolk sac tumour in a child: a case report.

Glomus tumours (GTs) primarily arise from glomus bodies that are located in the dermis layer of skin. However, they can be encountered ectopically in most parts of the body. As a result of researches done in a 17-month-old male patient who prssented to us with complaint of an increasingly growing swelling, he was diagnosed with a yolk sac tumour.

Neuroblastoma arising from an unresected sacrococcygeal teratoma in a child.

Malignant transformation of a germ cell tumor, referring to the occurrence of somatic, nongerm cell malignancy within a germ cell tumor is a rare entity. The authors report a case of malignant transformation of an unreseceted sacrococcygeal teratoma to neuroblastoma in a 6-year-old girl and discuss this case in the light of relevant literature. This case shows that complete resection of germ cell tumor is necessary to prevent malignant transformation.

Investigation of histopathologic changes in pelviureteral junction obstruction.

Objectives: This study aimed to determine histopathologic changes in the pelviureteral junction in children with pelviureteral junction obstruction.

Material And Methods: Seventeen pelviureteral junction specimens obtained from children were divided into two groups: pelviureteral junction obstruction (n = 7) and control (n = 10). Wall thickness of the pelviureteral junction, tunica muscularis of the pelviureteral junction, uroepithelium thickness of the pelviureteral junction, and collagen thickness of the pelviureteral junction were evaluated in resected pelviureteral junctions in children with pelviureteral junction obstruction.

Colon agenesis with ileovesical fistula and anorectal malformation.

Colonic agenesis is a rare cause of congenital bowel obstruction and is usually associated with other malformations such as abdominal wall defects or gastrointestinal, cardiac, urogenital, and musculoskeletal lesions. Although many uncommon types have been reported, ileovesical fistula (IVF) associated with total colonic agenesis (TCA) has not been reported in a newborn with anorectal malformation (ARM). This is the first report of a 1-day-old newborn with ARM, IVF, and TCA.

Effects of fasting and preoperative feeding in children.

Aim: To investigate whether children should undergo surgery without a long period of fasting after feeding.

Methods: Eighty children with inguinoscrotal disorders (aged 1-10 years) were studied prospectively. They were divided into eight groups that each contained 10 children who were fed normal liquid food (NLF) and a high-calorie diet (HCD) 2, 3, 4 and 5 h before surgery, in two doses at 6-h intervals.

Investigation of histopathologic changes in the ureter walls in vesicoureteral reflux.

Purpose: This study aimed to determine the histopathologic changes in ureteral walls (UWs) in children with vesicoureteral reflux (VUR).

Methods: Twenty ureteral specimens taken from children were divided into 2 groups, refluxing (R) and control (C) groups, each containing 10 specimens. Wall thickness of the ureter, tunica muscularis of the ureter, mucosal thickness of the ureter (uroepithelium), collagen thickness of the ureter, mucosal change, and inflammation were evaluated in resected distal UWs in children with VUR.

Investigation of histopathologic changes in the ureter walls in experimental congenital obstructive uropathy.

Background/purpose: The aim of this study is to determine the histopathologic changes in the ureter wall in experimental urinary bladder hypoplasia and agenesis.

Methods: Timed pregnant rats were randomly divided and received intraperitoneal Adriamycin (ADR) at 2 mg/kg on gestational days (GD) 6 to 9 (ADR group) and saline at 2 mL/kg on GD 6 to 9 (SF group). The control (C) group did not receive any medication in their pregnancy.

Mesenchymal hamartoma of the liver mimicking hepatoblastoma.

Mesenchymal hamartoma of the liver is a cystic benign liver mass occurring in children. Diagnostic confusion with hepatoblastoma may arise when alpha-feto-protein (AFP) level is elevated. We report an extremely rare case of mesenchymal hamartoma in an 11-month-old boy.

Spermatic cord hydatid cyst: an unusual localization.

Lesions of the groin include hernia, hydrocele, spermatic cord cyst, undescended testes, lymphadenopathy, and abscess. Hydatid cysts are endemic in certain regions of the world. They are usually located in the liver, lung, spleen, brain, and kidney.

A rare presentation of true hermaphroditism: an abnormal inguinoscrotal mass.

This study examined the differential diagnosis of inguinoscrotal masses and true hermaphroditism as well as incarcerated inguinal hernia in the differential diagnosis of abnormal inguinoscrotal masses. Inguinoscrotal masses are a rare presentation of true hermaphroditism. A child with an inguinoscrotal mass of the right groin and penoscrotal hypospadias was diagnosed.

Hepatoblastoma in a child with neurofibromatosis type I.

A major hallmark of NF1 is the development of benign tumors, including peripheral neurofibromas, plexiform neurofibromas, gliomas of the optic tract, other low grade gliomas, and pheochromocytomas. Hepatoblastoma have not been previously reported in patients with neurofibromatosis type 1. We present a case of a 9-month-old boy diagnosed with both hepatoblastoma and neurofibromatosis type 1.

Frequency of pharyngeal reflux in children with adenoid hyperplasia.

Objectives: The purpose of the study is to investigate whether there is any association between pharyngeal reflux and adenoid hyperplasia by using 24-h esophageal pH monitoring with a dual probe in children.

Methods: The study group consisted of 30 children with adenoid hyperplasia, and the control group consisted of 12 healthy children, studied prospectively. All children underwent 24-h esophageal pH monitoring with a dual probe (distal and proximal esophageal pH monitoring).

Pharyngeal reflux in children with chronic otitis media with effusion.

Objective: To investigate whether there is an association between chronic otitis media (COM) with effusion and pharyngeal reflux in children by using 24-h pH monitoring with a dual probe.

Material And Methods: This was a prospective study. The study group consisted of 25 children with COM with effusion and the control group comprised 12 healthy children.

Galactorrhea-associated granulosa cell tumor in a child.

Granulosa cell tumor of the ovary is a rare form of ovarian cancer in children. An 11-year-old girl was admitted with complaints of galactorrhea and abdominal mass. Abdomino-pelvic ultrasound and computed tomography revealed an ovarian tumor.

Intestinal ischemia-reperfusion and plasma enzyme levels.

Determination of blood levels of intracellular enzymes is an appropriate method to evaluate tissue and organ damage. To show systemic tissue damage resulting from intestinal ischemia-reperfusion, New Zealand rabbits underwent 60 min intestinal ischemia and 60 min reperfusion. Plasma samples were obtained before and at 55, 70, and 120 min after operation and enzyme levels were determined.

Effect of antioxidant therapy on collagen synthesis in corrosive esophageal burns.

To investigate the efficacy of antioxidant therapy on collagen synthesis in corrosive esophageal burns, 110 Sprague-Dawley rats were divided into five groups of 22 animals each. A standard esophageal caustic burn was produced by 1 ml of 10% sodium hydroxide solution for the rats in groups B to E; group A was instilled only with 0.9% saline after preparation of the distal esophageal segment.
