A case of osteochondritis dissecans of talus developed in a 10-year-old girl is reported Since the first description by Konig in 1888 of this entity, many has been reported but that of ankle joint has been of lesser occasion. Clinical diagnosis in this case could be made with the painful swelling and tenderness on the lateral aspect of the left ankle for four months with roentgenological demonstration of marked sclerosis of the separted fragment of the left talus. Surgical removal of the detached fragment was successful with uneventful functional recovery of the joint.

A case of congenital absence of the fibula in a 27-year-old man was reported. Discrepancy in length of both tibiae reached 7cm (65cm to 72cm) and the calf muscle atrophy was striking. Associated were the complete absence of fibular ray of the foot and the great toe and second toe could only be recognized in a hyperplastic, rudimentary, and deformed state. Built up shoe with prosthesis for the foot restored the length difference and stability of the foot.

BACKGROUND: To evaluate the usefulness of exercise echocardiography in diagnosis of coronary artery disease and to compare it with exercise ECG test. METHOD: We performed exercise test in 48 patients who suffered from angina-like chest pain, according to the modified Bruce protocol. During exercise, we observed the ECG changes and recored the images of left ventricular wall motion before and after exercise on the video tape. The echocardiogram were digitally stored and displayed in a format that allowed simultaneous analysis of rest and stress images. Newly developed left ventricular wall motion abnormalities were determined as positive findings. RESULTS: The feasibility of exercise echocardiography was 75%. The sensitivity and specificity fo exercise ECG test was 67% and 89%. The sensitivity and specificity of exercise echocardiography was 85% and 100%. The sensitivity of ECG and echocardiography was 50%(7 of 14) and 78.6%(11 of 14) in those with one-vessle disease and 84.6%(11 of 13) and 92.3%(12 fo 13) in those with multi-vessle disease. CONCLUSION: Exercise stress echocardiography was very usefull method for detecting the coronary artery disease especially in single vessle disease. And it had much higher accuracy than the stress ECG test.

PURPOSE: To compare the Doppler velocity waveform pattern of ophthalmic artery of hypertensive patients with that of normotensive subjects. MATERIALS AND METHODS: Doppler velocity waveform was obtained from ophthalmic artery in 45 hypertensive patients and 60 normotensive subjects. Both hypertensives and normotensive subjects were classified according to age into those younger than and those older than 45 years. Doppler indices[pulsatility index(PI), resistance index(RI), the first systolic peak/the second systolic peak(S1/S2), the first sytolic peak/diastolic peak (S1/D)] measured in hypertensive patients were compared with normotensive subjects. RESULTS: Among the various doppler indices, only S1/S2 showed significant difference(p < 0.05) between the hypertensive patients and normotensive subjects younger than 45 years. Doppler velocity waveform of hypertensive patients older than 45 years showed no significant difference from that of normotensive subjects with corresponding age. CONCLUSION: Doppler velocity waveform of ophthalmic artery in hyopertensive patients younger than 45 years shows pattern with S2 higher than that of normotensive subjects. High S2 component(reflective-wave) may represent increased vascular impedance ~ue to vasococonstriction of retinal arterioles in hypertensve patients.

Lymphoepithelial carcinoma is a rare subtype of undifferentiated carcinoma in the salivary gland. The incidence of lymphoepithelial carcinoma is about 0.4% among the patients with major salivary gland tumors. It has a racial preference; about 75% of the patients are of Mongolian ancestry. We report a case of lymphoepithelial carcinoma arising in the left parotid gland of a 52-year-old man. Grossly, the tumor was relatively well demarcated, gray-white, and solid. Microscopically, the irregular shaped syncytial tumor cell islands were evident within lymphoplasma cell-rich and desmoplastic stroma. The carcinoma cells had large vesicular nuclei and prominent nucleoli. The tumor invaded the surrounding salivary gland tissue. Epstein-Barr virus (EBV) was demonstrated by in situ hybridization for EBV-encoded RNA-1 (EBER-1) and polymerase chain reaction for EBV nuclear antigen-1 (EBNA-1).
