Latex allergy.

Latex allergy continues to be an important medical problem. In this review we re-examine the definition of latex allergy, the offending allergens, the factors that enhance sensitization, the threshold levels that sensitize and elicit reactions in sensitized individuals, current diagnostic techniques, avoidance measures, the barrier properties of nonlatex alternatives, and the roles of premedication and immunotherapy. Twenty years after its resurgence, latex allergy is a well-defined condition with established diagnostic criteria and rational treatment and prevention strategies. However, in spite of advances associated with molecular studies of latex allergens and improved understanding of immunotherapy, avoidance remains the only effective treatment.

Diurnal rhythms of aminopyrine metabolism: failure to sleep deprivation to affect them.

After a single oral dose of aminopyrine (9 mg/kg), mean salivary aminopyrine half-lives (t 1/2s) and metabolic clearance rates in 12 normal male volunteers exhibited diurnal variations. Salivary aminopyrine t 1/2s were approximately 50% longer at 8 P.M. (2.1 +/- 0.7 hr) than at 8 A.M. (1.4 +/- 0.3 hr). Mean aminopyrine metabolic clearance rates decreased 20% from 8 A.M. (418.2 +/- 152.0 ml/min) to 8 P.M. (335.3 +/- 107.6 ml/min). There were large interindividual variations in the magnitude of these diurnal changes in aminopyrine t 1/2 and metabolic clearance rates. There were nonsignificant changes in mean aminopyrine apparent volumes of distribution (aVd) which increased only slightly from 53.1 +/- 20.6 L at 8 A.M. to 59.7 +/- 26.5 L at 8 P.M. There were diurnal variations in plasma 11-hydroxycorticosteroids (11-OHCS), mean values of which decreased 60% from 16.2 +/- 4.2 microgram/100 ml at 8 A.M. to 6.5 +/- 1.9 microgram/100 ml at 8 P.M. Sleeplessness for 24 or 48 hr under the conditions of this experiment failed to affect diurnal rhythms in aminopyrine metabolism or plasma 11-OHCS concentrations.
