Characterization of aerobic non-lipophilic coryneforms from human feet.
Aerobic coryneform bacteria from human feet have been studied by analysis of the cell-wall sugars, lipids and diamino acids and by phenotypic tests. Although many isolates studied fall into the established genus Brevibacterium at least two previously unreported taxa of coryneform have been identified bringing the number of aerobic, non-lipophilic taxa known on skin to four. Simple tests can be used to distinguish between these taxa. Studies on the human skin flora continue to reveal the diversity of organisms present.

Toxicological determination of benzodiazepines in serum: methods and concentrations associated with high-dose intravenous therapy with diazepam.
This paper describes a rapid and simple procedure for the determination of benzodiazepines in biological samples. Five common benzodiazepines (diazepam, oxazepam, clorazepate, flurazepam, and chlordiazepoxide) and/or their major metabolites are extracted from a buffered serum sample at pH 9.2 by a mixture of toluene, hexane, and isoamyl alcohol. The phases are separated by centrifugation, and a small aliquot of the organic layer is injected into a gas chromatograph equipped with an electron-capture detector. The drugs are identified and quantitated by comparison with standards simultaneously processed similarly. A sample can be analyzed in about 30 min. The technique is illustrated by its application to sequential samples from a patient being treated for delirium tremens with large intravenous doses of diazepam. Serum diazepam, N-desmethyldiazepam, and oxazepam concentrations several times higher than usually encountered therapeutically were observed.

Two fatal cases of venlafaxine poisoning.
Venlafaxine is a phenethylamine derivative that has recently been approved for use in the treatment of depression. It is chemically unrelated to tricyclic, tetracyclic, or other available antidepressant agents. Anticholinergic, hypotensive, hypertensive, and cardiotoxic side effects are rare. Two fatal cases encountered at separate laboratories are discussed, both involve high levels of venlafaxine. Concentrations of the drug in peripheral blood, heart blood, urine, vitreous humor, and liver are reported. Descriptions of extraction and gas chromatographic methods for confirmation and quantitation are included.

Acetaldehyde, methanol, and ethanol analysis by headspace gas chromatography.
This report describes a headspace procedure suitable for the gas chromatographic assay of acetaldehyde, methanol, ethanol and various other volatile substances in biological samples. Carbopack B coated with 5% Carbowax 20-M is compared to Carbopack C coated with 0.2% Carbowax 1500. Assay range, linearity and precision are reported for the Carbopack B material.

Isolation of Malassezia sympodialis from feline skin.
Carriage of Malassezia yeasts was investigated in 17 cats in two colonies using a lipid-supplemented culture medium. Malassezia pachydermatis was isolated from one cat. Lipid-dependent Malassezia yeasts with electrophoretic karyotypes consistent with M. sympodialis were isolated from all six cats in one group and from one of 11 in the second group. To our knowledge, this is the first report of the isolation of lipid-dependent yeasts from cats.
