[Cecal volvulus].

The cecum is the second most common site of colonic volvulus after the sigmoid. The mechanism is torsion or hyperflexion of the enlarged, poorly-fixed, and hypermobile cecum. It presents clinically as an acute bowel obstruction with strangulation. Diagnosis can be made by plain abdominal X-ray in more than half the cases on the basis of cecal distention (with a classical "teardrop" or "comma" appearance), proximal small bowel distention with air-fluid levels, and a gasless distal colon. Barium enema shows lack of filling of the cecum, often with a "beaked" termination of the column of contrast. CT images are pathognomonic when they reveal a cecal "vortex". After surgical reduction of the torsion, ileo-cecal resection is usually the best therapeutic alternative. Cecopexy may be aDDrouriate in older and debilitated Datients if there is no concomitant cecal necrosis.

Evaluation of day-old specific pathogen-free chicks as an experimental model for pathogenicity testing of intestinal spirochaete species.

Specific pathogen-free chicks aged 1 day were challenged per os with strains of five different species of intestinal spirochaete originally isolated from pigs or human beings. A virulent strain of Serpulina hyodysenteriae (WA 15) colonized chicks, causing retarded growth rate and histological changes, including caecal atrophy, epithelial and goblet cell hyperplasia, and crypt elongation. A further strain of S. hyodysenteriae (SA3), which was apparently avirulent for pigs, and a strain of Serpulina intermedia (889) colonized fewer chicks, caused less severe lesions and did not significantly depress growth rate. Strains of Serpulina murdochii and Brachyspira aalborgi failed to colonize or cause histological changes. Four strains of Serpulina pilosicoli (Kar, Rosie-2299 and GAP 401, isolated from human beings, and 3295, isolated from a pig) colonized chicks, and large numbers showed polar attachment to the caecal epithelium; all strains, apart from Rosie-2299, caused watery diarrhoea and wet litter, but did not significantly retard growth. Variation both in the degree of spirochaetal attachment and the resulting development of lesions was observed between S. pilosicoli strains as well as between individual chicks infected with the same strain. The study indicated that chicks may be useful in studying the pathogenicity of strains of S. hyodysenteriae, S. intermedia and S. pilosicoli.

Lateral wall cecal filling defects following successful hydrostatic reduction of cecalcolic intussusceptions.

Two children less than 1 yr of age were found to have a lateral wall filling defect following successful hydrostatic reduction of cecalcolic intussusceptions. Both filling defects were thought to be due to invagination of the lateral wall between the tinea coli. One child was explored due to recurrence of the intussusception despite despite a decrease in size of the filling defect. In the second child the filling defect had disappeared three days after the initial barium enema reduction. When confronted with a typical cecal filling defect in an infant following successful reduction of a cecalcolic intussusception, we believe that one is justified in assuming a cautious "wait and see" attitude. If the child recovers clinically the barium enema may be repeated in three days to access reduction in size or disappearance of the filling defect.

Herniation of the appendix through the umbilical ring following umbilical artery catheterization.

A case of herniation of the appendix through the umbilical ring following transection of the umbilical cord for arterial catheterization is described. After the appendix was returned into the abdominal cavity and the peritoneal edges closed, the patient had no further difficulty. This rare complication of catheterization can be avoided by careful palpation of the umbilical stump and use of a moist bias tape around the base of the umbilicus prior to transection of the cord.

Cystic duplication of the cecum lined by dermal type squamous epithelium.

This is a case report of a cystic duplication of the cecum in a 6-month-old female infant, which was lined by both columnar and squamous epithelium. This squamous epithelium did not resemble esophageal epithelium but dermal epithelium. The so-called split notochord theory can explain the possibility of the coexistence of ectoderm and entoderm components. However, the present case had no vertebral abnormalities.

Cecal volvulus in a 2-month-old baby.

A case of primary cecal volvulus in a 2-month-old boy is reported. He is probably the youngest patient to be reported with this condition.
