Intussusception of sigmoid colon in an adult. Spontaneous expulsion of sequestered bowel and restoration of bowel continuity.

A 67-year-old white man presented with bloody diarrhea and passed a 22-cm long segment of full-thickness sigmoid colon following a barium enema. He had advanced peripheral and cerebral vascular disease and had undergone pelvic irradiation for a bladder cancer five years previously. He recovered uneventfully from the bowel sloughage. This was apparently due to an intussusception of the sigmoid colon followed by the formation of adhesions between the edges of the adjacent viable bowel.

A study of false positive and negative responses in the tube leucocyte adherence inhibition (tube LAI) assay.

A panel of 5 different breast-cancer and 2 other cancer extracts was used to clarify the false-negative responses in patients with Stage I and II breast cancer and the false-positive responses in control subjects. Most patients with Stage I and II breast cancer who had an initially negative LAI response were positive when tested against the panel. The false negatives occurred because of (1) the experimental errors of the assay; (2) changes in the antigenic strength of the extracts; (3) antigenic heterogeneity of a few tumours and (4) lack of tumour-specific reactivity of the host. 3% of control subjects had a false-positive LAI response. The leucocytes from most of these positive patients did not react to the panel of antigens, and hence the false positives appeared to result from experimental error. In-hospital patients with benign breast disease had a 12% positivity rate when initially assayed, and 63% of these patients reacted to the panel of breast-cancer antigens. Those patients with benign breast disease who reacted to the panel of breast-cancer antigens had cytophilic anti-breast-cancer antibody in their serum; their leucocyte LAI reactivity was blocked in an immunologically specific manner by serum from advanced Stage IV breast-cancer patients; their leucocytes reacted to extracts of breast cancer and not fibrocystic breast tissue; their leucocyte reactivity was blocked by isolated breast-cancer TSA that was linked to beta 2 microglobulin, but not by normal breast-tissue proteins; and the kinetics of the LAI response after excision of the breast mass was identical to that observed with breast-cancer patients after mastectomy. In these patients, the breast tissue within the breast lump expressed breast TSA similar to unequivocal breast cancer.

Intestinal tuberculosis: experience at a Canadian teaching institution.

Thirteen cases of inflammatory bowel disease suspected to be intestinal tuberculosis are analyzed. In nine, the diagnosis was established from such criteria as caseation necrosis, positive acid-fast stains or cultures of the diseased tissue. In four others, enteric tuberculosis remained a diagnostic possibility as judged by the following criteria: coexistence of the bowel lesion with established tuberculosis elsewhere, a clear response to antituberculous chemotherapy, or typical features on roentgenographic, surgical or histologic examination. The patients with intestinal tuberculosis were not necessarily recent immigrants or poor, nor did they have coexistent active pulmonary disease. Although most exhibited classic features of intestinal tuberculosis, the diagnosis was rarely considered at first. A greater awareness of the entity is needed to avoid confusion between intestinal tuberculosis and Crohn's disease.

Prognosis in colon cancer: a pathologic reassessment.

One hundred forty-eight cases of colon carcinoma were subjected to further pathologic study. Survival was correlated with stage and grade of the tumor and with the number of involved lymph nodes. In addition, cases were assessed as to the extent of local chronic inflammatory reaction about the lesion and the degree of sinus histiocytosis in draining lymph nodes. A correlation was possible between grading, staging, extent of lymph node involvement, and survival. A substantial difference in five-year survival was shown when local inflammatory reaction was present and when sinus histiocytosis was observed. The presence of both of these factors further improved survival. An adequate evaluation of these factors, both individually and in combination, should improve our ability to assess prognosis in colon cancer.

Post-operative renal failure caused by disseminated intravascular coagulation.

A 22-year-old man suffered a stab wound of the femoral artery and vein. This was followed by disseminated intravascular coagulation. Renal failure then occurred presumably due to fibrin deposition in the small vessels of the kidney. The D.I.C. was successfully treated with heparin and the renal failure with peritoneal dialysis. It is suggested that D.I.C. and consequent alterations in regional blood flow following trauma are not uncommon, and search should be made for these phenomena in every case of major trauma.

Chronic toxicity of a synthetic tri-aryl phosphate oil to fish.

Rainbow trout (Salmo gairdneri) were exposed to IMOL S-140, a synthetic high-temperature lubricating oil composed of tri-aryl phosphates and, although no sign of acute toxicity was evident, the fish slowly developed symptoms of chronic posioning. Thus, floating food pellets were refused, the activities of glutamic oxalacetic transaminase and lactate dehydrogenase in serum were greatly elevated, and internal fatty tissues became discoloured. Neither serum nor brain cholinesterase activities were inhibited.

Quantitation of intraepithelial lymphocytes in human jejunum.

An estimate of the number of intraepithelial lymphocytes in jejunal villous epithelium can be obtained by differential counting of nuclei in the epithelium. From counts carried out in 160 jejunal biopsies from patients who did not have coeliac disease the normal range has been established as 6-40 intraepithelial lymphocytes per 100 villous epithelial cells. In some biopsies there was a moderate increase in the intraepithelial lymphocyte count; this was probably an objective measurement of ;increased chronic inflammatory cell infiltrate'. Intraepithelial lymphocyte counts were high in untreated coeliac disease; counts were lower, but rarely within the normal range, in coeliac patients on a gluten-free diet. Counts were normal in most autoimmune diseases, ulcerative colitis, and Crohn's disease. There were abnormal intraepithelial lymphocyte counts in four patients, with otherwise normal jejunal histology, in whom no cause had been found to explain prolonged and incapacitating gastrointestinal symptoms.
