[Endoscopy and histology in the diagnosis of inflammatory intestinal diseases].

Colonoscopy is now a routine examination in the diagnosis and the follow-up of I.B.D. The most typical aspects of endoscopic and histological lesions are described. Colonoscopy and histological study of endoscopic biopsies permit a differential diagnosis of Crohn's disease and ulcerative colitis in 90% of the cases. Certain cases remain indeterminate even after colectomy.

Epidemiology of Clostridium difficile-induced intestinal disease.

The epidemiology of Clostridium difficile-induced intestinal disease is an intriguing subject about which there are few answers but many remaining questions. Although it is accepted that altered intestinal microecology (usually the result of antimicrobial therapy) is a major predisposition to disease, the details of microbial interactions are not yet known and clearly involve more than simple overgrowth of a resistant member of the resident flora. A variety of reservoirs of C. difficile are recognized. These include endogenous carriage, environmental contamination, and zoonoses, but the relative epidemiologic importance of these varied sources is yet to be determined. Because minor variations in methods for cultivation of C. difficile can markedly affect the ability to detect the organism, even the prevalence of endogenous carriage by various populations is not fully defined. There is good evidence for nosocomial acquisition of disease, but the frequency of this event and the usefulness of preventive measures need to be determined. The development of a typing system would provide a valuable tool for investigating many of the remaining questions. Finally, in addition to the recognized risk factors, which include the apparently predisposing alteration in intestinal microecology and exposure to C. difficile, there appear to be other, as yet undefined, variables that help to determine whether disease will occur. Perhaps the elucidation of the details of the pertinent microbial interactions as well as an understanding of the relevant host-pathogen relationships will provide important insights into the epidemiology of C. difficile-induced disease.

Nonsecretory variant of immunoproliferative small intestinal disease: a case report with pathologic, immunophenotypic, and molecular findings.

We report a case of the nonsecretory variant of immunoproliferative small intestinal disease involving the distal small bowel and the mesenteric and retroperitoneal lymph nodes in a 19-year-old woman from Mexico. This variant extranodal marginal zone B-cell lymphoma appeared similar in the different sites of involvement, with more interspersed large cells and greater plasmacytic differentiation present in intestinal specimens. Characteristic lymphoepithelial lesions and follicular colonization were seen in intestinal and lymph node sections, respectively. The neoplastic B cells were cytoplasmic immunoglobulin (Ig) A heavy-chain restricted and lacked surface and cytoplasmic light-chain expression by flow cytometric analysis. Serum and urine protein electrophoresis/immunofixation revealed hypogammaglobulinemia with no paraprotein. Molecular studies showed absence of immunoglobulin heavy-chain (IgH) gene rearrangement, with a nonfunctional clonotypic rearrangement of the kappa light-chain gene. This case highlights the role for kappa light-chain gene evaluation in immunoproliferative small intestinal disease, because IgH gene rearrangement analysis is often negative.

Clinical and laboratory characterization of Basenjis with immunoproliferative small intestinal disease.

Eleven adult Basenji dogs with immunoproliferative small intestinal disease (IPSID) were studied. Two items of history related to the digestive tract were characteristic: (i) chronic intractable diarrhea in most dogs, and (ii) progressive emaciation. Anorexia was intermittent in only a few dogs. In addition, skin lesions of various degrees of severity were observed, including alopecia of pinnae and ventrum, hyperpigmentation and hyperkeratosis of pinnae, and necrosis and ulcerations of margins of pinnae. The cause of the skin lesions was not determined; however, hypothyroidism did not appear to contribute to the skin changes. Standard hematologic and serum chemical values were not consistently abnormal. However, a poorly regenerative anemia, mild neutrophilia, and increased aspartate aminotransferase and alanine aminotransferase activities were generally observed in severely affected dogs. The Pelger-Huet anomaly was identified in dog 3. Maldigestion and malabsorption as determined by the N-benzoyl-L-tyrosyl-p-aminobenzoic acid and d-xylose test was documented to varying degrees in dogs with IPSID. Maldigestion was correlated with functional pancreatic exocrine insufficiency. Severe malabsorption was documented in only 3 dogs. Serum gastrin values were evaluated in these dogs because of a prior observation of parietal cell hyperplasia and gastric ulceration. Hypergastrinemia was documented in 3 dogs. Additional studies will be necessary to determine whether an acid hypersecretory state contributes to the pathogenesis of IPSID in Basenjis.

[Ophthalmologic complications in chronic inflammatory intestinal diseases].

Through investigations which we performed ophthalmological complications in chronic inflammatory intestinal disease are revealed. It could be demonstrated that in most cases ocular symptoms are associated with joint troubles which in their turn depend on the severity of the general disease. Especially in elderly patients with longstanding history it is important to co-operate with representatives of other medical branches in the control of ocular complaints, since there may quickly occur functional deterioration when the eye is also involved.
