[Activity of small intestine alkaline phosphatase in the feces in chronic intestinal diseases].

In comparison to normal controls (n = 71) the activity of intestinal alkaline phosphatase in feces is reduced in chronic bowel disease using an immunoprecipitation method: patients with Crohns disease (n = 40) or inactive ulcerative colitis (n = 29) demonstrate small changes of fecal intestinal alkaline phosphate activity in comparison to normal controls. Intestinal alkaline phosphatase is reduced in patients with active ulcerative colitis (n = 11) to 50%, in patients with uraemic enteropathy (n = 18) to 30% and in patients with coeliac disease (n = 14) to 20% of the activity observed in normal controls. During cytostatic treatment of malignant tumors, fecal intestinal alkaline phosphatase activity increases as a sign of toxic damage of the intestinal mucosa.

Derangements of mucosal growth and differentiation in small-intestinal diseases.

Physiologically, there is a balance of cell proliferation and exfoliation which maintains normal small-intestinal mucosal zonation with long villi and shallow crypts. In disease states and in the experimental animal this balance may be disturbed by numerous exogenous and endogenous factors, which may lead to three principally different responses: mucosal atrophy, mucosal hypertrophy, and mucosal transformation of the hyperregenerative type. The structural and functional characteristics of these different mucosal patterns are described, and their pathophysiologic relevance is discussed.

[Anal symptoms of gastro-intestinal diseases].

In most cases the ano-cutaneous clinical symptoms correlated to diseases of the gastro-intestinal tract are not specific (erythema, itching, wounds or scarring). However in the following diseases occasional dermatological lesions may directly contribute to their diagnosis: in Crohn's disease, tuberculosis of bowel, chronic entamoebiasis and bilharziosis, the skin lesions of the anal area have the same histological structure as the gut lesions. Perianal fistulas and ulcers are frequent in Crohn's disease especially if there is a colonic and rectal spreading; they respond badly to steroid therapy and are often correlated with a worse prognosis. Perianal specific lesions occur often in oxyuriasis in children, in candidiasis of the digestive tract, in systemic aphthosis and in some malignancies. In other gastro-intestinal disturbances, the dermatological and features are less specific and can only be suggestive: iatrogenic and microbial diarrheas, side-effects of laxatives, proctological diseases. It has to be emphasized that pruritus ani is only induced by deeper lesions when they spread to the perianal skin. In proctological practice, contact dermatitis by sensitivity to anaesthetics or suppository balsams (Peruvian balsam), itching or burning atrophy by topical steroid abuse, non-diagnosed fungal (candidiasis), bacterial (erythrasma) or psoriatic intertrigos (flexural psoriasis) may sometimes explain the failure of therapy.
