Objectives: To evaluate the validity of ultrasound for diagnosis and exclusion of pyloric stenosis in the infants with nonbilious vomiting. Methodology: In a cross-sectional study, 444 consecutive infants with clinical suspicion of pyloric stenosis were evaluated by ultrasound (US) and categorized as pyloric stenosis or not according measuring parameters as muscle thickness, muscle width and ca...
Four studies reported an increasing incidence of pyloric stenosis during the late 1970s from geographically diverse areas of the United Kingdom. It was suggested that the increased incidence might be related to changes in infant feeding practices. We used data from the Metropolitan Atlanta Congenital Defects Program, a population based birth defects registry, to examine the secular trends and d...
CONTEXT Pyloric stenosis is the most common condition requiring surgery in the first months of life. Case reports have suggested familial aggregation, but to what extent this is caused by common environment or inheritance is unknown. OBJECTIVES To investigate familial aggregation of pyloric stenosis from monozygotic twins to fourth-generation relatives according to sex and maternal and patern...
The neuropeptide, red pigment concentrating hormone (RPCH), strengthened the inhibitory synapse from the lateral pyloric (LP) neuron to the pyloric dilator (PD) neurons in the pyloric network of the stomatogastric ganglion (STG) of the lobster, Homarus americanus. RPCH produced several-fold increases in the amplitude of both action potential-mediated and non-impulse-mediated transmission that p...
The accumulation of Cd, Pb, Zn, and Cu in the starfish Asterias rubens was studied in a Norwegian fjord characterized by a gradient of metal pollution in the sediments, ranging from very high metal concentrations at its head to much lower levels at its opening. The concentrations of metals in starfish from natural populations along the gradient (long-term accumulation) and in starfish that were...
Introduction: Early diagnosis of biliary atresia is very important for better outcome of treatment. Ultrasonography is one of the diagnostic tools for early differentiation of biliary atresia from other causes of neonatal cholestasis. It has been reported that triangular cord sign (TACS) in sonography is a reliable sign for diagnosis of biliary atresia. The aim of this study was to re-assess ...
