The value of 121 flexible bronchoscopy (FB) procedures was evaluated in 54 children, aged three months to 14 years, suspected of having pulmonary tuberculosis. Specimens from FB were culture-positive for Mycobacterium tuberculosis in seven of the 13 bacteriologically confirmed cases. Bronchial abnormalities consistent with the diagnosis were found in 31 of 54 cases. Separate or coexistent findi...

Computer tomography (CT) is an effective technique in the initial evaluation of the abdomen and head following blunt trauma. To evaluate the role of CT of the thorax, a prospective study comparing routine early thoracic CT scanning with initial chest roentgenogram (CXR) was carried out on 73 patients with blunt torso trauma undergoing concomitant abdominal CT examination. Initial CXR and CT sca...
