1.The Difference of Interpretations of Cardiopulmonary Exercise Testing According to Interpretative Algorithms and Exercise Methods.
Tuberculosis and Respiratory Diseases 2001;50(1):42-51
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 primary malignant melanoma arising in the leptomeninges of the central nervous system is extremely rare. We report a case of malignant melanoma, apparently thought to be originated from leptomeninges, with diffuse neoplastic process widely spreaded over the leptomeninges of 42 years old man, who had suffered severe headache, nausea and left hemiparesis. This patient is free of the symptoms for six months after operation. The literature on this subject is briefly reviewed.

Twin reversed arterial perfusion (TRAP) sequence is a rare specific anomaly of twin gestation with fused placenta and umbilical anastomosis. This syndrome occurs once in about 34,600 births and reported first by Beneditti in 1533. We report on prenatal diagnosis of a case of TRAP sequence with color Doppler sonography, this case is presented with a brief review of the literature.
