[Evaluation of the control measures adopted against an epidemic of AIDS-related multidrug-resistant tuberculosis in a Latin-American hospital].

Background: Since 1992 AIDS-related multidrug-resistant tuberculosis (MDRTB) has been detected among patients admitted to the Hospital Muñiz in Buenos Aires (Argentina). The aim of the present study was to evaluate the effectiveness of the control measures adopted against the nosocomial spread of MDRTB/AIDS, which affected 803 patients between 1992 and 2002.

Methods: An action plan was applied that included bacilloscopy screening on admission, isolation rooms for patients with TB/AIDS, an isolation ward for patients with MDRTB/AIDS, a radiometric method for the diagnosis of multidrug-resistance, a reserve supply of second line drugs, and respiratory protection for health care workers.

[Respiratory distress due to pulmonary hemorrhage in leptospirosis].

Two patients who lived in Buenos Aires suburbs died from leptospirosis in July 2000 and March 2001. They developed a nonspecific febrile illness followed by hemorrhagic pneumonia and respiratory distress in absence of typical manifestations such as jaundice, nephropathy, thrombocitopenia or hemorrhages in other organs. In the house and surroundings of one patient rodents were captured and three strains of leptospira, serogroup Icterohaemorrhagiae were isolated.
