Failure of absorption of baclofen after rectal administration.

We wished to determine the degree to which baclofen was absorbed from an aqueous vehicle after rectal administration. A comparison was made to absorption after oral administration. After oral administration, the baclofen half-life was 2.3 to 3.4 hours and peak serum concentrations were achieved from 1 to 2.1 hours after administration. No measurable absorption was observed after rectal administration of the drug in any subject. Rectal administration of baclofen is not a clinically sound treatment option when oral administration of the drug is not possible. For patients receiving chronic baclofen therapy, other medications such as a benzodiazepine should be considered at times when oral administration of medication is not possible.

A comparison of the effects of low- and conventional-dose thiazide diuretic on insulin action in hypertensive patients with NIDDM.

In conventional doses, thiazide diuretics impair glucose tolerance and decrease insulin sensitivity, making them an unpopular choice for treating diabetic patients with hypertension. However, use of low-dose thiazide diuretics may avoid the adverse metabolic effects seen with conventional doses. In a double-blind, randomised crossover study we assessed peripheral and hepatic insulin action in 13 hypertensive non-insulin-dependent diabetic patients after a 6-week placebo run-in and following two 12-week treatment periods with either low (1.25 mg) or conventional (5.0mg) dose bendrofluazide. There were no differences between doses in their effects on systolic and diastolic blood pressure. Bendrofluazide 1.25 mg had significantly less effect on serum potassium, uric acid, fasting glucose and HbA1C concentrations than the 5.00 mg dose. Exogenous glucose infusion rates required to maintain euglycaemia were significantly different between doses (p < 0.05) with conventional-dose bendrofluazide worsening peripheral insulin resistance compared to baseline (23.8 +/- 2.9 vs 27.3 +/- 3.5 mumol.kg-1.min-1, p < 0.05) and low-dose bendrofluazide producing no change compared to baseline (26.8 +/- 3.6 vs 27.3 +/- 3.5 mumol.kg-1.min-1, p = NS). Postabsorptive endogenous glucose production was higher on treatment with bendrofluazide 5.0 mg compared to 1.25 mg (11.7 +/- 0.5 vs 10.2 +/- 0.3 mumol.kg-1.min-1, p < 0.05) and suppressed to a lesser extent following insulin (4.0 +/- 0.7 vs 2.0 +/- 0.4 mumol.kg-1.min-1, p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Lack of tearing after Le Fort I osteotomy.

An unusual complication of lack of tearing after a Le Fort type I osteotomy for maxillary retrusion has been presented. A definite cause for the complication can only be postulated. The possibilities of this problem occurring may be prevented by more delicate use of osteotomes in the separation of the pterygoid plates.
