In this month's Journal, Dr. Rangel-Frausto and colleagues add to accumulating evidence reinforcing the pressing need to develop a workable alternative t...

Interpretation of tuberculin tests would be easier if the tuberculin test profiles in different communities were accurately known. We reviewed 468 Mantoux test reactions in patients coming to Hospital Universiti Sains Malaysia with suspected tuberculosis. Eighty six percent of patients with active tu...
BACKGROUND Erythema induratum (EI) manifests as tender indurated nodules on the lower legs. It may be associated with concomitant active tuberculosis (TB) and is considered a hypersensitivity reaction to mycobacterial antigens. However, the results of Mycobacterium cultures are rarely positive, and the tuberculin skin test is of limited usefulness in populations exposed to bacille Calmette-Guér...
The tuberculin skin test currently used to diagnose infection with Mycobacterium tuberculosis has poor diagnostic value, especially in geographic areas where the prevalence of tuberculosis is low or where the environmental burden of saprophytic, nontuberculous mycobacteria is high.
