Interstitial cells of Cajal (ICCs) are pacemaker cells which are densely distributed throughout the whole gastrointestinal tract. ICCs have important functions in neurotransmission, generation of slow waves and regulation of mechanical activities in the gastrointestinal tract, especially for the coordinated gastrointestinal peristalsis. Therefore, a loss of(More)
BACKGROUND/PURPOSE Routine contralateral groin exploration in girls with unilateral inguinal hernia (UIH) continues to be controversial. The aim of this study was to determine the incidence of contralateral hernia development in girls after UIH repair. METHODS Between 1972 and 2000, 391 girls underwent repair of UIH. Ninety-one (23%) of the 391 girls(More)
INTRODUCTION Congenital diaphragmatic hernia (CDH) is a complex malformation. The majority of children after CDH repair lead normal life, with good exercise tolerance. However, in some patients, long-term sequelae are observed, resulting from the primary defect and implemented treatment. MATERIAL AND METHODS We evaluated (basing on clinical examination(More)
We describe the presence of c-kit positive interstitial cells of Cajal-like (ICCs-like) in the walls of the urinary bladders of children. An immunohistochemical study of specimens, obtained at autopsy from either the trigonum (Group A) or the corpus (Group B), was performed using antibodies against c-kit (CD 117). Histological morphometry of the(More)
PURPOSE C-kit positive interstitial cells of Cajal (ICCs) play an important role in the regulation of the smooth muscle motility, acting as pacemakers to provide the slow wave activity in various organs. Recent studies have shown that c-kit positive ICCs are widely distributed in the urinary tract of animals and humans. The aim of our study was to examine(More)
Transplantation of whole pancreas or pancreatic islets remains a promising approach to treatment of diabetes mellitus. Since there is no efficient method presently known for in vivo detection of pancreatic islet rejection, we have utilized dithizone [DTZ] to monitor the survival of transplanted islet allografts following the induction of tolerance by a new(More)
Congenital diaphragmatic hernia (CDH) in most cases presents immediately or within hours after birth with signs of respiratory failure: dyspnea, tachypnea, and cyanosis. Late presentation of CDH (beyond the neonatal period) is less common and represents true diagnostic challenge. Diagnosis of the defect is difficult. Symptoms are non-specific and can be(More)
The authors present results of studies in a group of 58 children aged 4-36 months in whom food allergy has been diagnosed. Esophageal 24-hour pH-metric studies revealed the presence of gastroesophageal reflux (GER) in 27 cases (46.5%). In 13 cases it was primary and independent of the allergic disease, and in 14 children it showed features of secondary(More)
INTRODUCTION Bezoars are concretions of human or vegetable fibers that accumulate in the gastrointestinal tract of humans and animals. Patients may remain asymptomatic for many years, and symptoms develop as bezoars increase in size to the point of obstruction or perforation. THE AIM OF THE STUDY WAS TO PRESENT: 3 cases of bezoars treated in our centre and(More)
OBJECTIVE To evaluate the efficiency of thoracoamniotic shunts for drainage of macrocystic-type congenital cystic adenomatoid malformation (CCAM). SUBJECTS AND METHODS This was a retrospective study of 12 fetuses with a large thoracic cyst treated with thoracoamniotic shunting between 2004 and 2014 in a tertiary fetal therapy center. Medline was searched(More)
