A cutaneous manifestation of untreated disseminated histoplasmosis.

We present a case of histoplasmosis with skin manifestations occurring 17 years after initial diagnosis. The clinical manifestations of disseminated disease are discussed. Amphotericin B administered through an A-V shunt resulted in prompt resolution of the skin lesions.

Immediate consequences of spinal cord injury: possible role of potassium in axonal conduction block.

Compression injury of the spinal cord of cats produced increased outflux of potassium from the damaged site. Conduction by large axons in sensory pathways of the spinal cord was blocked partially by bathing the cord in solutions containing potassium concentrations of the order of 50-100 mEq/liter. It is suggested that block by increased K+ concentration in the extracellular space could interfere with long tract function immediately after cord injury before the onset of gross structural changes, and that increased extracellular potassium may be a link in the mechanisms producing thses later changes.

Magnesium and other electrolytes in bovine eyeballs immersed in sea water and other fluids.

Bovine eyeballs were immersed in fluids including sea water for variable intervals of time, and magnesium concentrations and those of other electrolytes were determined in the aqueous and vitreous humor. Magnesium values increased with time, but no final saturation was reached nor were the levels obtained as high as those previously reported. In human immersion fatalities, Mg++ increased comparably to the most closely stimulating experimental situation, that is, corneal exposure in an unstirred medium. At best, vitreous Mg++ appears to be an imperfect marker in estimating the length of immersion, and then only if the sample remains unhemolyzed and the total post-mortem interval is considered. Establishing or excluding the diagnosis of drowning solely by this technique seems unlikely because of ion diffusion into the eye fluids.

Evaluation of consumer drug information databases.

OBJECTIVES: To evaluate prescription drug information contained in six consumer drug information databases available on CD-ROM, and to make health care professionals aware of the information provided, so that they may appropriately recommend these databases for use by their patients. DESIGN: Observational study of six consumer drug information databases: The Corner Drug Store, Home Medical Advisor, Mayo Clinic Family Pharmacist, Medical Drug Reference, Mosby's Medical Encyclopedia, and PharmAssist. SETTING: Not applicable. PATIENTS OR OTHER PARTICIPANTS: Not applicable. INTERVENTIONS: Information on 20 frequently prescribed drugs was evaluated in each database. The databases were ranked using a point-scale system based on primary and secondary assessment criteria. MAIN OUTCOME MEASURES: For the primary assessment, 20 categories of information based on those included in the 1998 edition of the USP DI Volume II, Advice for the Patient: Drug Information in Lay Language were evaluated for each of the 20 drugs, and each database could earn up to 400 points (for example, 1 point was awarded if the database mentioned a drug's mechanism of action). For the secondary assessment, the inclusion of 8 additional features that could enhance the utility of the databases was evaluated (for example, 1 point was awarded if the database contained a picture of the drug), and each database could earn up to 8 points. RESULTS: The results of the primary and secondary assessments, listed in order of highest to lowest number of points earned, are as follows: Primary assessment--Mayo Clinic Family Pharmacist (379), Medical Drug Reference (251), PharmAssist (176), Home Medical Advisor (113.5), The Corner Drug Store (98), and Mosby's Medical Encyclopedia (18.5); secondary assessment--The Mayo Clinic Family Pharmacist (8), The Corner Drug Store (5), Mosby's Medical Encyclopedia (5), Home Medical Advisor (4), Medical Drug Reference (4), and PharmAssist (3). CONCLUSION: The Mayo Clinic Family Pharmacist was the most accurate and complete source of prescription drug information based on the USP DI Volume II and would be an appropriate database for health care professionals to recommend to patients.
