[Tuberculosis 1992: current clinical aspects, epidemiology and diagnosis].
We review four different aspects of tuberculosis (TB), a disease which is making a comeback as a focus of medical attention. The diagnosis of TB in HIV infected individuals can be very challenging for the clinician and an increased number of side effects complicates treatment. Updated information in this area appears necessary for physicians who are in charge of HIV-infected patients. The "cursed duet" of TB and HIV infection is also responsible for the increase of TB in subsaharan Africa. Recent data are discussed in relation to this issue. Another problem for developing countries is the diagnosis and treatment of children's TB, which involves particular features as compared to the adult form of the disease. Finally, new diagnostic methods are now available from the laboratory. The detection of mycobacteria with the polymerase chain reaction has proven very useful in the diagnosis of tuberculous meningitis. Detection of tuberculostearic acid and mycobacterial antigen also represent important advances. The role of these techniques in the diagnosis of TB forms other than meningitis will need to be defined in the near future.
