Nontuberculous Mycobacteria, especially Mycobacterium avium complex (MAC) infection is a common opportunistic infection in patients with acquired immunodeficiency syndrome (AIDS). In patients with AIDS, MAC infection more frequently presents as disseminated form rather than localized infection. Disseminated MAC infection is associated with a high mortality rate in patient with AIDS. We report a case of disseminated MAC infection in an AIDS patient involving bone marrow, mediastinal lymph node and lung.

It is difficult to distinguish a lung cancer from a pulmonary tuberculoma or other benign nodule. It is even more difficult to identify the type of lesion if the mass shows no change in size or demonstrates slow growth. Only a pathological confirmation can possibly reveal the nature of the lesion. A 61-year-old-woman was referred for a solitary pulmonary nodule. The nodule showed no change in size for the first two years and continued to grow slowly. Pathological and immunological analyses were conducted for confirmation of the nodule. The nodule was identified as a well-differentiated primary pulmonary adenocarcinoma. An LULobectomy was performed, and the post surgical stage of the nodule was IIIA (T2N2M0). Even though there are few risk factors, there is still the possibility of a malignancy in cases of non-growing or slow growing solitary pulmonary nodules. Therefore, pathological confirmation is encouraged to obtain a firm diagnosis.

OBJECTIVES: The in-training examination (Performance Examination, PE) for psychiatric residents in Korea was launched 5 years ago by the Korean Neuropsychiatric Association (KNPA). This article analyzes 5-year accumulated data on the PE, and tries to make some suggestions for further development of the PE. METHODS: The 5-year data, previously utilized for the generation of formal annual reports were reanalyzed, with an emphasis on longitudinal trends. RESULTS: The analyses indicated the following; 1) Higher-year residents earned definitely higher scores than their lower-year colleagues on the PE. This trend was especially prominent in the area of psychopharmacology-biological psychiatry, geriatric psychiatry, child and adolescent psychiatry, and the emergency-organic psychiatry. There was no year-related performance difference in the area of psychoses. 2) In the area of anxiety-somatization disorder, psychophysiological disorder, and geriatric psychiatry, the residents in the university-affiliated hospitals outperformed those in the specialized psychiatric hospitals. 3) Through analyzing multiple-times examinees, it was found that their first-and second-time performances were moderately correlated, and that their ranks tended to improve, demonstrating a continuously improving performance according to the training year. CONCLUSION: These result suggested that the KNPA PE is a feasible measure for the estimation of an individual resident's performance as well as the adequacy of the environment provided by the training institutes.
