Exomphalos and gastroschisis: a 10-year review.

Ninety-six cases of exomphalos or gastroschisis managed at The children's Hospital, Sheffield, during the period 1964-74 are analysed. There were 306 cases with minor lesions, 30 with major lesions, 27 with a ruptured exomphalos and only 3 with gastroschisis. The overall mortality rate was 46-9 percent. Survival could be closely correlated with the birth weight, the nature of the primary lesion, the presence or absence of liver within the sac and the presence and severity of associated congenital anomalies. A "scoring system" based on these criteria is proposed to predict the prognosis of an infant with an exomphalos.

Immunoepidemiology of intestinal helminthic infections. 3. Mucosal macrophages and cytokine production in the colon of children with Trichuris trichiura dysentery.

Mucosal macrophages and accessory cells have been studied by immunohistochemistry in the lamina propria of the colon of children with Trichuris trichiura dysentery syndrome (TDS). No difference was found in the numbers of cells recognized by the monoclonal antibodies CD11c, CD68, or RFD7 between TDS children and local controls. However, large numbers of cells were recognized by an antibody against calprotectin (an anti-bacterial glycoprotein found in tissue infiltrating-monocytes) in TDS colonic mucosa, but few in control colon. Large numbers of cells containing tumour necrosis factor alpha (TNF alpha) were also seen in TDS mucosa; cells isolated from TDS mucosa secreted more TNF alpha than cells from control mucosa; and children with TDS had high levels of circulating TNF alpha. Non-specific macrophage-mediated inflammation and local cytokine production may therefore play a role in the pathogenesis of TDS.

Papillary cystic neoplasm of the pancreas. Report of a case diagnosed by fine needle aspiration cytology.

Fine needle aspiration (FNA) performed on a young woman who presented with a mass in the left hypochondrium yielded fluid. Smears and Cytospin preparations of the fluid showed good cellularity, consisting of relatively monomorphic cells forming a perivascular papillary pattern. FNA cytology thus suggested a diagnosis of papillary cystic neoplasm of the pancreas. Surgical removal of the pancreatic tumor and detailed histologic study confirmed the cytologic diagnosis.
