To determine whether inactive hepatitis B surface antigen (HBsAg) carriers are at a higher risk of drug-induced hepatotoxicity than control subjects during antituberculosis treatment with standard short-course regimens of isoniazid, rifampin, ethambutol, and/or pyrazinamide. ⋯ Tuberculosis treatment in HBsAg-positive and HBeAg-negative inactive carriers could be pursued in the usual manner, using standard short-course regimens of isoniazid, rifampin, ethambutol, and/or pyrazinamide, with the condition that monthly liver function tests are performed.

Pneumococcal pneumonia is the most common etiology for community-acquired pneumonia. The prevalence of lymphadenopathy seen on CT scans in these patients is uncertain. The purpose of this series was to assess the prevalence of intrathoracic lymphadenopathy in hospitalized patients with pneumococcal pneumonia. ⋯ Lymphadenopathy is a common CT scan feature of pneumococcal pneumonia in hospitalized patients, in a variety of settings. Therefore, when a patient with pneumococcal pneumonia has lymphadenopathy seen on a CT scan, other etiologies for the lymphadenopathy need not be suspected.
