Spinal infection by Mycobacterium xenopi in a non-immunosuppressed patient.

A previously fit 77-year-old woman was found to have a paravertebral abscess. This was aspirated, yielding Mycobacterium xenopi, but no other pathogens. Antituberculosis chemotherapy with four first-line agents was commenced, with some response but continuing pain. Reports of extrapulmonary M. xenopi infections are rare. Most previous cases have involved immunosuppressed patients. This is the first reported case of spinal M. xenopi infection in a non-immunosuppressed patient, but radiological evidence suggests that previous tuberculous infection may have damaged the lumbar vertebrae, rendering them susceptible to infection by M. xenopi.

Racial variation in serum creatine kinase unrelated to lean body mass.

In a group of 30 black and 30 white healthy workers, matched for age, sex and body weight, serum creatine kinase was significantly higher in black males than in white males (P less than 0.01). Seventeen blacks but only four whites had levels above the accepted upper limit of normal of 195 IU/l. There was no correlation with lean body mass. Elevation of serum creatine kinase need not signify disease in blacks, for whom a separate reference range should be established. Two cases are reported of physically healthy black men subjected to unnecessary investigation on the basis of persistently elevated serum creatine kinase.

Prednisolone absorption in inflammatory bowel disease: correlation with anatomical site and extent.

Prednisolone absorption was studied in 13 normal subjects, eight patients with ulcerative colitis and 21 patients with Crohn's disease, by measuring plasma levels after a single oral dose. Absorption of the drug was delayed in all patient groups. The peak plasma level of the drug was lower in patients with extensive small bowel Crohn's disease. Patients in this category may need higher doses of oral prednisolone than other patients with inflammatory bowel disease.
