Visualization of pulmonary arteriovenous malformation by three dimensional computed tomography: a case report.

Pulmonary arteriovenous malformation (PAVM) is an anomaly condition characterized by abnormal vascular communications between arteries and veins in the lungs. Hereby we describe a 60-year-old female with PAVM. Although the patient was asymptomatic, an abnormal round opacity was found on a chest X-ray film. Computed tomography (CT) of the lung disclosed nodules connected with enlarged vessels. Because PAVM was suspected, the patient was further evaluated by spiral CT coupled with three dimensional reconstruction of the images (3D-CT). As a result, PAVM was clearly visualized and invasive procedures such as angiography was not performed. The present case illustrates that 3D-CT is a diagnostic procedure of choice when PAVM is suspected.

[Tuberculosis in elderly].

We compared patients with active tuberculosis treated at Kurume University Hospital between cases 65 years and above and below 65. The comparison included immunologic and clinical features. Anergy to tuberculin skin tests with purified protein derivative (PPD) was evident in 7% of patients under 65 and in 14% of those over 65. Older patients had fewer lymphocytes in peripheral blood and lower serum concentrations of interferon (IFN)-gamma than younger patients. Complications were more frequently seen in patients above 65, but the time required for negative conversion of sputum cultures did not differ by age. Adequacy of the regimen of chemotherapy and the sensitivity to anti-mycobacterial drugs were the most important determinants of the time for negative conversion of sputum culture. Major clinical problems of old tuberculosis patients were concurrent diseases, bed ridden states, necessity of nursing care, and poor performance status of patients.
