Effect of an H2-receptor blocking agent on diarrhoeas after extensive small bowel resection in Crohn's disease.

The effect of an H2-receptor blocking agent, cimetidine, on faecal losses of fluid, electrolytes and fat was examined in 10 patients with Crohn's disease, who had diarrhoeas after extensive small bowel resection. A randomized, double-blind and cross-over design was applied, and patients were hospitalized and on a defined diet during the study. Cimetidine, 4 x 400 mg, significantly reduced diarrhoeal volumes by an average of 22% (p less than 0.05) and faecal sodium by 27% (p less than 0.05). Patients with severe diarrhoeas responded better to treatment. No side-effects were recorded. The reported data suggest that cimetidine may be useful in symptomatic treatment of patients with severe diarrhoeas after extensive ileal resection. Due to deficient drug absorption, higher doses may be needed for optimal effect.

Intralipid clearance and lipoprotein pattern in men with advanced alcoholic liver cirrhosis.

Twelve male patients with advanced alcoholic cirrhosis of the liver were found to have markedly low serum lipid and lipoprotein concentrations. Serum triglyceride and cholesterol concentrations were about 50% of matched control values. The very low density lipoprotein-triglyceride concentration was only one-third of control values and the cholesterol concentrations in very low density and low density lipoproteins were far below control values. The mean high density lipoprotein cholesterol concentration was not significantly decreased, but in three of 12 patients extremely low values were found. These findings may reflect a failure of lipoprotein synthesis secondary to a bad nutritional state and metabolic disturbances in this advanced stage of liver cirrhosis. By means of the intravenous fat tolerance test with Intralipid it could be shown that substantial amounts of triglycerides could be cleared from the plasma in these patients. However, studies on the long-term Intralipid clearance capacity have to be performed before any general recommendations about the inclusion of fat emulsions in parenteral nutrition of these patients can be made.

Transtracheal stimulation of the recurrent laryngeal nerve.

Phonation was induced in 10 mongrel dogs under general anesthesia by way of transtracheal stimulation of the recurrent laryngeal nerves under conditions of constant air flow. Although stimulation voltages were approximately 10 times the voltage required for direct stimulation, no cardiac or respiratory abnormalities were observed. Photoglottographic and electroglottographic signals were the same for both direct and transtracheally induced phonation. This phonation induction method can be used in chronic animal preparations to study vocal fold vibration sequentially and may be clinically applied to the treatment of patients with laryngeal problems that have failed to respond, or are not amenable, to standard forms of vocal rehabilitation.
