[Intra-digestive fermentation in intestinal malabsorption syndromes: relations with elevated serum activity of gamma-glutamyl-transpeptidase].

Unlabelled: The aim of this prospective study was to examine the relationship between gastrointestinal ethanol production ("Mei-Tei-Sho" syndrome described in Japan) and biological liver dysfunction associated with intestinal malabsorption syndromes.

Methods: Sixty-five patients with malabsorption-diarrhea underwent 98 simultaneous measurements of plasma gamma-glutamyl-transpeptidase and of faecal ethanol concentrations; in 5 cases, ethanolemia and faecal ethanol concentrations were measured after a 250 g rice-meal; in 1, ethanol concentration was measured in a sample of caecal liquid in hours following local instillation of fructose (40 g).

Results: Faecal ethanol was detected at least once in 60/65 patients (74/98 measurements, maximum 3.

[Measurement of energy expenditure at rest in nutritional disorders. Study in 229 patients].

Resting energy expenditure was measured by indirect calorimetry, and body composition was evaluated by electrical body impedance analysis in 229 female patients with anorexia nervosa, cancer, non tumoral disease, obesity, and 42 healthy women. Results were compared with theoretical formulas based on anthropometry, and expressed by kilogram of body weight and lean body mass. Each group was compared with each other and with controls.

[Prognostic value of nutritional parameters in gastrectomy for cancer: a study of 203 cases].

Two hundred and three patients underwent a gastrectomy for 1981 to 1985, as a treatment for gastric carcinoma. This retrospective study focuses on survival and the prognostic value of oncological features as topography, local involvement and size of the tumour, and nutritional features as albuminemia, prealbuminemia and weight loss. Although prealbuminemia and weight loss have a prognostic value, albuminemia has not this classical value.

Serum levels of carcinomedin (1-keto-24-methyl-25-hydroxycholecalciferol) as an indicator of the progression of cancer. Preliminary results of a prospective study.

The serum levels of the cholesterol derivative 1-keto-24-methyl-25-hydroxycholecalciferol found in patients with cancer varies after surgical, chemical or radiotherapy treatments. The serum level associated with the vitamin profile has a predictive value for evaluating progress of the disease and therapeutic efficacy. The detection, identification and assay of a vitamin D3 derivative, 1-keto-24-methyl-25-hydroxycholecalciferol, named carcinomedin by us, in the serum of cancer patients was described in prior work.
