BACKGROUND: Recently, cardiopulmonary exercise testing (CPX) has become a popular diagnostic method for differentiating the main cause of exertional dyspnea or exercise limitation. We evaluated the difference in the CPX results according to interpretative algorithms and the methods of exercise in Korea. METHOD: Sixty-six patients with chronic lung disease and 48 adults with dyspneic symptoms, but with no abnormalities in a spirometry performed symptom limited CPX, were included in this study. The results were interpreted using both Wasserman's(WA) and Eschenbacher's algorithm (EA), and a comparison between both algorithms was made. Thirty-three healthy medical students performed the CPX with a cycle ergometer and treadmill. The results were interpreted with EA and the concurrenec in interpretations was evaluated according to the methods of exercise. RESULTS: 1. In patients with chronic lung disease, the overall concordance rate between the two algorithms was 63.6%. The concordance rates were 69.8% in patients with obstructive, 25.0% in those with restrictive, and 66.7% in those with mixed pulmonary insufficiency. In patients with dyspneic symptoms but normal findings in resting spirometry, the concordance rate was 60.4%. 2. In healthy medical students, in results interpreted with EA, the concordance rate between the cycle ergometer and treadmill exercise was 25.0%. CONCLUSION: Both interpretative algorithms and methods of exercise may affect the CPX results. In using CPX as a diagnostic test for the causes of dyspnea in the Korean population, the interpretative algorithms and method of exercise need to be standardized, and a predictive VO2max equation needs to be established.

The occurrence of a fistula between the duodenum and the colon is very rare, although these two structures commonly lie in intimate relationship to each other. It is not uncommon for tumor of the right colon and proximal transverse colon to involve the duodenum by continuity, but fistulous connection between the duodenum and colon are infrequent In most of the reported malignant cases, the fistulas follow carcinomas of the transverse colon or the hepatic flexure of the colon. We report a rare case of malignant duodenocolic fistula which was first suspected by endoscopic examination and confirmed by operation.

Sertoli-Leydig cell tumor is a rare sex-cord stromal tumor of the ovary and accounts for less than 0.5% of all ovarian tumors. It is among the most fascinating from pathologic and clinical viewpoints in masculinization. We experience an unusual case of a poorly differentiated Sertoli-Leydig cell tumor in 60-year-old woman who showed masculinization and present it with brief review of literature.

BACKGROUND: Despite concern about treatment of sporotrichosis, little is known about the sensitivity of S. schenckii against antifungal agents. OBJECTIVE: The purpose of the study was to investigate minimal irihibitory concentration(MIC) of antifungal agents against S.chenckii. METHOD: The tested strains were seven in number. The tested antifngal agents were ketoconazole, itraconazole, amphotericin B, and potassium iodide. A various concentration of drugs were mixed into fluid media containing 50% ethanol, dimethyl sulfoxide, and distilled water. The inoculum consisted of 3mm block containing hyphae and spores. RESULTS: MIC ranges of ket.oconazole, itraconazole, amphotericin B, and potassium iodide were 0.39- 25pg/ml, 0.78-25pg/ml, 0.78-25pg/ml, and 75-550pg/ml, respectively. CONCLUSION: We find that ketoconazole is the most active drug against S. schenckii.
