Simultaneous measurement of plasma and gastric immunoreactive carcinoembryonic antigen (CEA) was performed in 108 patients undergoing upper gastrointestinal endoscopy. Gastric immunoreactive CEA was more sensitive than plasma CEA (92% vs. 65% positive) in patients with gastric cancer. In cancer patients gastric CEA was significantly higher than in all other(More)
A case of documented Sézary syndrome, a cutaneous T-cell lymphoma, with gastrointestinal lymphocytic infiltration is presented. The symptom of diarrhea waxed and waned with the course of the disease process. Radiographic studies were normal, and no evidence of malabsorption was elicited. The diagnosis was established by endoscopic and biopsy techniques,(More)
Nine patients with malignancy requiring chemotherapy were evaluated before, during, and in the recovery phase of their antineoplastic regimen with selected absorptive studies and jejunal biopsies. Depression of the crypt mitoses occurred without change in the indices of absorption. The mitotic indices returned to pretreatment counts on the recovery phase(More)
It is now well documented that a characteristic mucosal lesion of the proximal small intestine is present in acute nonbacterial gastroenteritis. To determine whether a gastric mucosal lesion also accompanies this illness, stool filtrate containing Norwalk agent was given orally to 15 volunteers after base line biopsies of gastric fundal and/or antral mucosa(More)
The histopathological changes that occur in the jejunal mucosa of humans infected with the Norwalk or Hawaii agent of acute infectious nonbacterial gastroenteritis ("viral" gastroenteritis) have ben well characterized. The pathogenesis of diarrhea in this syndrome remains unknown; however, recent reports have suggested a possible role for the adenylate(More)
