Improved healing with a collagen-alginate dressing in the chemical matricectomy.

A prospective clinical trial was conducted to evaluate the efficacy of a collagen-alginate wound dressing in the postoperative management of chemical matricectomies. The study involved 20 patients and 23 separate procedures. The collagen-alginate-dressing treatment group had an average healing time of 24.

Matrix and modifier effects in the supercritical fluid extraction of cocaine and benzoylecgonine from human hair.

The supercritical fluid extraction (SFE) behavior of cocaine and its major metabolite benzoylecgonine (BZE) was investigated and found to be highly dependent upon the chemical nature of the matrix and the manner in which the target drug analytes are incorporated into or on the matrix. The recovery of cocaine from Teflon wool, filter paper, drug-fortified hair, and drug user hair was studied using a variety of CO2/modifier mixtures. Incorporation of a triethylamine (TEA)/water modifier mixture provided dramatic improvements in the recovery of cocaine from interactive matrixes.

An evaluation for compensated anterior cavus.

Anterior cavus is a multiplane structural deformity that can originate from different areas within the foot. Differentiation of these areas is a necessary examination in order to determine the effect of proper treatment. A depressed fourth and fifth ray or lateral column is a major deformity in anterior cavus.

An examination procedure for cavo-adducto-varus.

This examination is used in cava-adducto-varus feet to determine the primary areas producing the secondary forefoot pathology. Table I is a compilation of the data and shows by means of an asterisk those pathologies possible with an additional primary deformity. The fold face test parts, when indicated in the exact order, are diagnostic.
