Patients with the irritable colon syndrome have an exaggerated and/or prolonged colonic motor response to eating. This is believed to be the cause of their postprandial complaints. Since the flux of calcium ions across cell membranes plays a major role in the contractions of the gastrointestinal smooth muscle, we investigated ...

A 52-year-old man with the clinical features of Cronkhite-Canada syndrome developed rectal cancer. Radiologic and endoscopic examinations revealed gastrointestinal polyposis. Histologic examination of the biopsied polyps showed cystic dilatation of glands with an inflammatory stroma. A later biopsy from a rectal polyp proved to be an adenocarcinoma. The totally resected ...

A 57-year-old male presented with abrupt melena. Numerous polypoid lesions were found in the stomach and colon accompanied by characteristic ectodermal changes of the Cronkhite Canada syndrome. He had undergone a left side hemicolectomy for colon cancer 3 years previously. Two months after the operation, he had noticed hyperpigmentation of ...

Assays of in vitro biological properties associated with cellular transformation revealed differences in cultured skin cells within the heritable colon cancer syndromes with polyposis coli. Such evidence suggested that genetic heterogeneity, long assumed from in vivo differences in extracolonic lesions in these syndromes, could be detected in vitro. None of ...

Pseudo-obstruction of the colon, or Ogilvie's syndrome, is characterized by an adynamic, dilated, unobstructed colon, the exact cause of which remains obscure. Although several precipitating factors have been described in the literature, we have observed three patients whose pseudo-obstruction of the colon occurred during interstitial and intracavitary pelvic irradiation. Such ...

Adenomas of the ileal mucosa are an uncommon finding in adenomatous polyposis coli/Gardner's syndrome. We report 9 patients who were found to have ileal adenomas 1 yr 11 mo to 25 yr 11 mo after colectomy. The ileal adenomas occurred proximal to an ileorectal anastomosis in 7 patients, both proximal ...

Two patients with the prune belly syndrome demonstrated colon calcifications and anorectal malformations. Bladder outlet obstruction was present in both cases. Calcifications were also found in the renal collecting system and bladder of one patient. No fistula was demonstrated between the genitourinary tract and bowel in either infant at autopsy. ...

Cnephia mutata was successfully induced to complete two entire generations in the laboratory. Owing to its triploid condition, this simuliid is parthenogenetic and mature eggs may be dissected from the ovaries, thus eliminating both mating and oviposition. C. mutata in Newfoundland is also autogenous, making blood-feeding unnecessary. Progress towards colonization ...

Neonatal small left colon syndrome is a cause of functional colon obstruction in newborn infants, with a high association of maternal diabetes. There has been much confusion regarding its relationship to meconium plug syndrome and aganglionosis. Six cases of aganglionosis (2 in infants of diabetic mothers) were encountered in which ...
