OBJECTIVE: To know the clinical features of overuse injury in performing musicians and to evaluate related factors that may affect the overuse injury and playing related pain. METHODS: Eighty professional musicians and music college students were examined during 1 year. All were examined by a history taking, physical examination, radiologic exam and if needed electromyography. Nonparametric Sperman's correlation were used for the statistic analysis and 5 interval grading system, visual analog scale for pain, and stress, criteria of joint hypermobility were used for various measurements. RESULTS: Fifty four men were studied in 3 music colleges and a professional orchestra. Frequency of symptom was 46.3%. The string players were most frequently affected (65%), whereas the wind instrument players were least frequently affected (11.5%). The most commonly affected site was the hand and wrist (54.2%) followed by the spine. Patients were divided by the severity into 5 groups and among them the grade 1 was most common (29.6%). No significant correlation was seen between the practice hours per week but a significant correlation was noted between the stress and playing related pain. Joint hypermobility plays an important role in music playing which is dependent on the kind of instruments. CONCLUSION: Incidence of the overuse injury in musicians is high in Korea and the prevention and early treatment are essential for the good outcome of overuse syndrome.

OBJECTIVE: To assess the jumper's knee for the symptoms and diagnostics by MRI and ultrasonography in basket ball players. METHOD: Twenty knees of 10 basketball players with chronic knee pain were assessed by the history taking, physical examination and diagnosis by magnetic resonance imaging and ultrasonography. Their average age was 17.4 years. Stanish classification is used for grading the symptoms of jumper's knee. RESULTS: Nine proximal patellar tendons were diagnosed as jumper's knees (45%) and 11 distal tendons were diagnosed as jumper's knees (55%). In ultrasonographic findings, average proximal patellar tendon thickness was 4.5 mm+/-1.2 mm, and distal patella tendon thickness was 7.1+/-1.1 mm. Sensitivity was 63% (12/19) and specificity was rated as 100% (21/21). By the MRI findings, sensitivity was rated as 32% (6/19) and specificity was rated as 90% (16/21). Study between the patient's clinical severity level by Stanish classification and thickness of patellar tendon showed no significant correlation (<0.5). CONCLUSION: The ultrasonography to be more convenient and easier as a diagnostic method for the jumper's knee than MRI.

BACKGROUND: For the purpose of early detection of breast cancer, a localization biopsy is necessary in case of mammographically or ultrasonographically suspicious, but nonpalpable, breast lesions. METHODS: One hundred nine consecutive localization biopsies for nonpalpable lesions of the breast were performed upon 101 patients from May 1992 to September 1998. RESULTS: The localizations were done in 48 cases under the guidance of mammography and in 61 cases under the guidance of ultrasonography. Complications occurred in 15 cases (13.7%). The mean volume of the excised specimens was 11.6 cm3. The miss rate was 3.6% (4 cases). Malignant lesions of the breast were found in 16 cases (14.7%). Among the malignant lesions, 10 cases involved invasive ductal cancer. Among the patients diagnosed as having breast cancer, 8 patients were treated with a conservative operation, 5 patients with a modified radical mastectomy, and 2 patients with observation; 1 patient was discharged. The chance of a biopsy containing a malignant lesion was 16.7% if the biopsy was done because of mass, 9.8% for a microcalcification, and 11.1% for an abnormal asymmetric density. CONCLUSIONS: A needle localization biopsy can be performed accurately under local anethesia, and the volume of the excised specimen can be minimized, so the cosmetic effect is excellent and proper early treatment is possible in diagnosed cases of breast cancer.

Giant cell tumor is a relatively uncommon neoplasm with high rate of local recurrence following curettage and bone graft. The histologic grading was not proven useful in predictiog outcome. Histologically benign giant cell tumor may metastasize. We report a case of histologically benign giant cell tumor occurred at left distai femur with local recurrences and multiple pulmonary metastases which was proven by percutaneous needle aspiration lung biopsy. Recurred local lesion was treated by curettage and filling with methylmethacrylate and pulmonary metastases was treated with adriamycine and dacarbazine.

OBJECTIVE: To evaluate the clinical course of the patient who had the gynecologic operation using minolaparotomy. METHODS: We reviewed the chart of the patient who had the gynecologic operation using minilaparotomy in department of obstetrics and gynecology of St. Mary's hospital during Jan. 2000 Sept. 2002. RESULTS: Postopertive diagnosis is myoma (154 cases), adenomyosis (41 cases), ovary cyst (89 cases) and so on. We had performed hysterectomy (225 cases), myomectomy (86 cases), cystectomy or adenexectomy (85 cases) for these patient. There is no significant difference in clinical course between two total hysterecomized groups, one who had the operation history and the other who had not the operation history. CONCLUSION: In gynecological operations, minilaparotomy is the useful methods in any kind of the indication of operation, and show good clinical course.

BACKGROUND: Color Doppler echocardiography is sensitive in detecting mitral regurgitation and useful in quantitating its severity. The presence of an eccentric regurgitant jet suggests that regurgitation is caused by prolapsing or flail leaflet of mitral valve. Until recently the direction of regurgitant jet in mitral valve prolapse has been examined in a single(parasternal short axis view) or orthogonal plane using color Doppler echocardiography, and few in the apical rotation method of a transducer. The purpose of this study was to clarify the usefullness of the apical rotation method of a transducer in detection of the direction of mitral regurgitant jet and diagnosis of the sites of mitral valve prolapse. METHODS: Twenty four patients(8 men and 16 women, mean age:47.3+/-18.8 years) with mitral valve prolapse with eccentric regurgitant jet were examined by two-dimensional and color Doppler echocardiograply using conventional parasternal long and short axis views, and four apical longitudinal planes(four chamber, vertical, two chamber and transverse views) obtained by the apical retation method of a transducer. RESULTS: Thirty one regurgitant jets were detected in twenty four patients, eighteen patients had anterior, nine patints posterior, and three patients bi-leaflet(anterior and posterior) prolapse. In eighteen patients with anterior leaflet prolapse, ten had medial, eight had middle, three had lateral, and three had two portions(two, medial and middle; one, middle and lateral) prolapse. In nine patients with posterior leaflet prolapse, five had medial, three had middle, two had lateral, and one had two(medial and middle) scallop prolapse. CONCLUSION: Color Doppler echocardiography by the apical rotation method of transducer is useful in assessment of the site of prolapse in patients with mitral valve prolapse with eccentric regurgitation.
