BACKGROUND/PURPOSE The etiology of meconium obstruction without cystic fibrosis is unclear. Interstitial cells of Cajal (ICC) function as pacemakers in gut motility and may play a role in the pathophysiology of the disease. METHODS The ICC were examined by immunohistochemical staining with anti-c-kit antibody in the bowel walls of 6 neonates who had meconium obstruction without cystic fibrosi...
OBJECTIVE The aim of this study was to review the radiological findings of three cases of total colon aganglionosis (TCA), hypoganglionosis, and immature ganglionosis, and to compare the differences in diagnosis and follow-up of these three disease entities. MATERIALS AND METHODS Three neonates with neonatal onset of abdominal distension with vomiting were investigated, and the cases were dia...
Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a rare disorder of enteric smooth muscle function affecting the intestine and bladder. Patients with this severe phenotype are dependent on total parenteral nutrition and urinary catheterization. The cause of this syndrome has remained a mystery since Berdon's initial description in 1976. No genes have been clearly linked to M...
Background Meconium ileus (MI) is one type intestinal obstruction due to inspissated meconium at the level of the terminal ileum. The purpose of this study is to present the non-ionizing ultrasound-guided approach for the treatment of meconium ileus. Materials and Methods This study was performed, prospectively, at Dr. Sheikh and Akbar children's Hospitals, Mashhad University of Medical Science...
The alpha3 subunit of the neuronal nicotinic acetylcholine receptor is widely expressed in autonomic ganglia and in some parts of the brain. The alpha3 subunit can form heteromultimeric ion channels with other alpha subunits and with beta2 and beta4 subunits, but its function in vivo is poorly understood. We prepared a null mutation for the alpha3 gene by deletion of exon 5 and found that homoz...
Transcripts for the beta2 and the beta4 nicotinic acetylcholine receptor (nAChR) subunits are found throughout the CNS and the peripheral nervous system. These two beta subunits can form heteromultimeric channels with any of the alpha2, alpha3, alpha4, or alpha5 subunits in heterologous expression systems. Nonetheless, the subunit composition of native nAChRs and the role of different nAChR sub...
Renal pelvic dilation refers to excessive of the fetal intrarenal collecting system. Although a different terminology is used, pelviectasis or pyelectasis most often mild dilation, and hydronephrosis reserved for severe cases that are more likely be clinically significant. Normal measurements anteroposterior renal pelvis diameter <4 mm at 16 27 weeks gestation <7 ≥28 gestation.1Odibo A.O. March...
