1/605. Familial enteropathy: a syndrome of protracted diarrhea from birth, failure to thrive, and hypoplastic villus atrophy. We have studied 5 infants with persistent severe diarrhea from birth and marked abnormalities of absorption associated with failure to thrive leading to death in 4 infants. Three had siblings who died and a sibling of a 4th is ill at present, all with a similar illness; 2 were the products of consanguinous marriages. Exhaustive investigation failed to identify a recognized disease entity in any patient. steatorrhea, sugar malabsorption, dehydration, and acidosis were severe in all patients, whatever the diet fed. Total parenteral nutrition was used, but excessive stool water and electrolyte losses persisted even when nothing was fed by mouth. There was no evidence of a hematological or consistent immunological defect in any infant and no abnormalities of intestinal hormones were noted. In the duodenal mucosa of all infants we saw similar abnormalities characterized by villus atrophy, crypt hypoplasia without an increase in mitoses or inflammatory cell infiltrate in the lamina propria and in villus enterocytes absence of a brush border, increase in lysosome-like inclusions, and autophagocytosis. In 3 infants studied by marker perfusion of the proximal jejunum we found abnormal glucose absorption and a blunted response of Na absorption to actively transported nonelectrolytes; in 2 there was net secretion of Na and H2O in the basal state. Our patients evidently suffered from a congenital enteropathy which caused profound defects in their capacity to assimilate nutrients. The similar structural lesion seen in the small intestinal epithelium of all of our cases undoubtedly contributed to their compromised intestinal function, but the pathogenesis of this disorder, if indeed it is a single disease, remains obscure.

| Laparoscopic operations are becoming more common and replacing more traditional surgical procedures. As a result, radiologists should be aware of some of the unique complications that may occur from these types of procedures. We report two cases of incarcerated bowel hernias in lateral trocar sites.

| We describe an 18-year-old girl with a 13-year history of mixed connective tissue disease whose clinical course was unique: she ultimately developed end-stage kidney and bowel disease that led to a protracted morbid clinical course. We report this case to alert pediatric nephrologists to the importance of early recognition of possible intestinal disease in these patients. Unfortunately, no therapy is currently known to reverse the pathological process in the bowel, but multiorgan transplantation might be an option if the numerous medical complications of end-stage bowel disease can be successfully controlled.

4/605. Perforated appendix presenting with disproportionate jejunal distention. Six cases of perforated appendix are presented in whom there was disproportionate gas distention of the jejunum without other radiographic signs of appendicitis. This appearance tended to divert one's attention from the offending cause in the right lower abdomen. ( info) |
5/605. intussusception following a baby walker injury. Serious abdominal injury as a result of a fall in a baby walker has not been previously reported. We present the case of a 13-month-old boy who developed intussusception following a fall down five stairs in a baby walker. Attempted hydrostatic reduction was unsuccessful. At operation, a bowel wall hematoma, serving as a lead point, was identified. This case adds another type of injury to the list of those previously associated with baby walker use. ( info) |
6/605. Acute abdominal pain as a leading symptom for Degos' disease (malignant atrophic papulosis). We report a case of a 16-yr-old white female patient with acute abdominal pain due to visceral involvement of Degos' disease that required extensive small bowel resection. skin manifestations of her disease had been present for 2 yr before the correct diagnosis. She died as a result of central nervous system involvement from Degos' disease. ( info) |
7/605. Autoimmune enteropathy with distinct mucosal features in T-cell activation deficiency: the contribution of T cells to the mucosal lesion. BACKGROUND: Autoimmune enteropathy is normally characterised by crypt hyperplastic villous atrophy with enterocyte autoantibodies, activation of mucosal lymphocytes and increased epithelial HLA-DR. This case involved a severely affected Portuguese infant who was found to have lymphocyte activation deficiency and demonstrated correspondingly distinct mucosal features. methods: A female infant of nonconsanguineous parents was treated for vomiting and diarrhoea, first with milk exclusion and then with parenteral nutrition. lymphocyte subsets and immunoglobulin concentrations were normal, but in vitro testing showed no activation in response to phytohaemagglutinin, candida, or purified protein derivative, although the response to interleukin (IL)-2 was intact. interleukin-2 deficiency was excluded. Analysis of jejunal biopsy specimens revealed only mild villous blunting with absent goblet cells, normal epithelial proliferation, and no crypt hyperplasia. The dense infiltrate of CD8 and CD4 T lymphocytes showed normal CD2 and CD3 expression but no activation or proliferation markers. HLA-DR was not increased on epithelium or lymphocytes. Thus, in addition to in vitro evidence for lymphocyte activation deficiency, the mucosal specimens showed no evidence of in situ T-cell activation. RESULTS: After development of overwhelming septicaemia, the patient died at 18 months, just before a planned bone marrow transplant. CONCLUSIONS: These findings confirm significant heterogeneity within autoimmune enteropathy. Formal immune function testing should be performed in all affected infants to identify T-cell activation deficiencies. The distinct mucosal findings suggest that activated T cells usually induce the crypt hyperplastic villous atrophy characteristic of classic autoimmune enteropathy. ( info) |
8/605. A case of pediatric Behcet's disease with intestinal involvement. We report a 6-year-old girl with recurrent oral aphthae, genital and perianal ulcers, and folliculitis-like erythema followed by intestinal symptoms. No ocular lesions were found. Her ailment was diagnosed as incomplete Behcet's disease with intestinal involvement. According to the literature, pediatric Behcet's disease is characterized by a low incidence of ocular lesions and a high incidence of intestinal involvement, as exhibited in this case. As intestinal lesions in pediatric Behcet's disease are often life-threatening, a barium enema must be given to exclude the possibility of intestinal involvement when pediatric patients with Behcet's disease complain of abdominal pain.

| We report a rare case of immunoblastic lymphadenopathy (IBL)-like T-cell lymphoma complicated by multiple gastrointestinal involvement, which appeared to be ameliorated by chemotherapy but resulted in perforative peritonitis. A 66-year-old Japanese woman who had generalized lymphadenopathy and eruptions was admitted to our hospital because of bloody stool. Colonoscopic examination revealed hemorrhagic ulcers in the terminal ileum and a saucer-like ulcer in the cecum. Gastrointestinal endoscopy revealed several ulcerative or elevated lesions in stomach and duodenum. biopsy specimens of these lesions and of a lymph node showed characteristic histological features of IBL-like T-cell lymphoma. The initial treatment with prednisolone (PSL) and cyclophosphamide (CPA) was effective. Six months after the treatment, however, she developed bloody stool again caused by multiple ulcerative lesions in the large intestine. The recurrence of the disease was determined histologically, and four courses of CPA, PSL, vinblastine sulfate and doxorubicin hydrochloride (CHOP) therapy were administered. One month after completing the CHOP therapy, she developed intestinal obstruction and then acute peritonitis resulting from perforation at an ulcer scar in the jejunum. Surgical treatment was successful, and histological examination demonstrated no lymphoma cells in the resected specimen. A gastrointestinal perforation should be recognized as a potential complication of IBL-like T-cell lymphoma, even during remission. ( info) |
10/605. Abdominal cerebrospinal fluid pseudocyst in a severely handicapped patient with hydrocephalus. We present a case of an abdominal cerebrospinal fluid pseudocyst as a rare complication of a ventriculoperitoneal shunt. The patient is a severely handicapped bedridden spastic quadriplegic with hydrocephalus. He underwent surgical reconstruction of a shunt tube because of shunt disconnection at the age of 12 years. fever and frequent vomiting developed 2 months after surgery, and abdominal fullness gradually became severe. He was diagnosed as having an abdominal cerebrospinal fluid pseudocyst on abdominal ultrasonography. If a shunt dysfunction is suspected, this type of cyst should also be considered, and abdominal ultrasonography should be performed as one of the screening tests for determining the cause of the shunt dysfunction.
