A 22 year old male presented with symptoms of gastric outlet obstruction. Endoscopy showed a hypertrophic nodular lesion around the pyloric opening with pyloric stenosis. The endoscopic biopsy and histopathological examination revealed tuberculosis involving the stomach, an extremely rare lesion.

Pyloric atresia is a rare congenital malformation. We report a case in a 5-day newborn with pyloric atresia type C. Authors emphasize the diagnostic difficulties and therapeutic challenges in a resource-limited country.

duplications of gastrointestinal tract are congenital anomalies found in about 0.2% of all children. these include the rare gastric duplication. we present such a cyst in a 14 years old girl with gastric outlet obstruction. she was found to have a noncommunicating antral duplication cyst .the cyst was managed by cystectomy and marsupialization. microscopically the duplication cyst contained a m...

cutis laxa (cl) is a rare congenital and acquired disorder characterized by loose and redundant skin with reduced elasticity. three types of congenital cutis laxa have been recognized. other findings are pulmonary emphysema, bronchiectasia, hernia and diverticulosis. we describe a female neonate involved by cutis laxa syndrome and a positive family history. we focus on the radiologic findings o...

 The endocrine cells of Salmo trutta macrostigma stomach and pyloric caeca have been investigated using immunohistochemical techniques. 8 antisera were tested and 6 of them were detected in the endocrine cells serotonin, somatostatin, substance P, galanin, CCK and neuropeptide Y. These immunoreactive cells are described for the first time in the stomach and pyloric caeaca of Salmo trut...

We report a case of recurrent gastritis with pyloric stenosis and cholangitis due to a rare variation in bile duct anatomy. A 72-year-old female patient showed recurrent gastral ulcers and biliary colic with cholangitis caused by gallstones in the main bile duct with an ectopic orifice in the prepyloric region and concurrent inflammatory pyloric stenosis. After temporarily successful endoscopic...

Different Shaker family alpha-subunit genes generate distinct voltage-dependent K+ currents when expressed in heterologous expression systems. Thus it generally is believed that diverse neuronal K+ current phenotypes arise, in part, from differences in Shaker family gene expression among neurons. It is difficult to evaluate the extent to which differential Shaker family gene expression contribu...

The amines dopamine (DA), serotonin (5-HT), and octopamine (Oct) each elicit a distinctive motor pattern from a quiescent pyloric network in the lobster stomatogastric ganglion (STG). We previously have demonstrated that these amines alter the synaptic strength at multiple, distributed sites within the pyloric network that could contribute to the amine-induced motor patterns. Here, we examined ...
