Traumatic constipation.

In 4 patients, trauma to the lumbosacral area produced abnormalities similar to those seen after resection of the nervi erigentes. Mechanisms of the resulting constipation and fecal incontinence for liquid stools included a prolonged transit time through the entire colon, a low rectal pressure, spasticity of the anal canal, and abnormal anal reflexes. Previous trauma to the lower spine must be considered in the differential diagnosis of chronic constipation.

Hypolipidemic effect of tibric acid. A comparison with clofibrate and placebo in type IV hyperlipoproteinemia.

The effects of tibric acid, clofibrate, and placebo were compared in type IV hyperlipidemic patients for a 6-month period. The patients were divided into two pathological level groups according to their baseline triglyceride levels. Compared to the placebo, both tibric acid and clofibrate reduced the mean serum triglyceride concentration in the high pathological level group; however, clofibrate was also effective in the low pathological level group. The effects on total cholesterol were less pronounced with the two drugs. No effect was observed on esterified cholesterol, phospholipids, free fatty acids, and fasting blood sugar. After a 6-week follow-up period under placebo, no rebound of the triglyceride and cholesterol levels could be observed after discontinuation of the two active drugs. The other biochemical changes observed after each active treatment are discussed in relation to the different degree of activity of each active drug and to the different baseline levels of triglycerides.

Dose-response to tibric acid: a new hypolipidemic drug in type IV hyperlipoproteinemia.

This double-blind study compares the effects of tibric acid at four different doses to that of placebo in type IV hyperlipidemic patients. Fifty patients, divided at random in five groups of 10 patients each, received one of the following treatments: placebo, tibric acid 500 mg, 750 mg, 1,000 mg, or 1,250 mg per 24 hr. The data suggest that the 1,000 mg and the 1,250 mg doses are effective in lowering the serum triglyceride levels after 6 wk of treatment; the effect on total cholesterol is less pronouced. No effect is observed on the concentration of serum esterified cholesterol, phospholipids, and free fatty acids. It is also shown that in the dose range studied, the best fitting curve defining the four mean values of triglycerides and total cholesterol obtained with the four active treatments did not deviate significantly from linearity. Due to lack of toxicity, tibric acid may be useful in the treatment of type IV hyperlipoproteinemia.

[Comparison of masked and endogenous depression using psychometric scales, endocrinological markers and pharmacological responses. Masked depression versus endogenous depression].

Masked depression refers to a concept of a phenomenological state, either endogenous or psychogenic where somatic symptoms replace sadness: Thirty patients were evaluated by RDC (22 endogenous and 8 masked depressions) wherein in the latter dysphoria was replaced by a nonreactive persistent somatic complaint. They were rated on Beck and Hamilton Depression Scales, on Hamilton and Trait-State Anxiety Scales and the NOSIE. All patients presented with insomnia, anorexia, loss of weight, diminished libido and anhedonia. Initial ratings were similar for both diagnostic groups except for a significantly higher agitation factor and lower retardation in masked depression. Although 59.9 percent of the subjects are positive on the dexamethasone test, only 1 masked depression did not suppress secretion of cortisol. After a randomized 30-day drug trial where patients were assigned to Clomipramine or Desipramine, patients in both groups show significant improvement on rating scales but diagnostic group drug treatment interaction exists on anxiety and agitation criteria.
