Our data suggest that for preventing tuberculosis in HIV-infected patients, a daily 2-month regimen of rifampin and pyrazinamide is similar in safety and efficacy to a daily 12-month regimen of isoniazid. This shorter regimen offers practical advantages to both patients and tuberculosis control programs.

Mounier-Kuhn syndrome is a rare clinical entity. It was described in 1932 to refer to the presence of tracheobronchomegaly. The clinical presentation is variable and it can occur in several different age groups. We present the case of a young man who was admitted to the hospital for an asthma exacerbation and was found to have tracheobronchomegaly on his CT scan. A review of the literature for this rare, but interesting, phenomenon is included.

CT scanning correctly identified all patients with PH with MPADs >34 mm and excluded all patients without PH when MPADs were <27 mm. We advocate that the measurement of MPAD by CT scanning can be quickly and easily performed by the clinician to screen for the presence of PH.

Flumazenil, a benzodiazepine receptor antagonist, is the drug of choice for the diagnosis and treatment of benzodiazepine overdose. We are presenting a patient with chronic alcoholism and alcoholic liver disease, who came with alcohol withdrawal symptoms and treated chlordiazepoxide. Subsequently he developed a prolonged change in mental status that required treatment for benzodiazepine overdose and hepatic encephalopathy with flumazenil infusion for 28 days.
