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: The cornified cell envelope (CE) is a unique structure found in the terminal differentiation of the skin. The precursor proteins of the CE are composed of many candidate structural proteins, among which invalucrin and filaggrin are important ones to participate in the complicated process of forming, the complex structure. OBJECTIVE: The purpose of this study was to evaluate the usefulness of expression of involucrin and filaggrin as markers of terminal differentiation in various skin disorders including tumors. METHODS: Immunohistochemical studies were performed in the formalin-fixed, paraffin-embedded skin samples of non-tumors (41 cases) and tumors (43 cases).

We report two cases of cellulitis on the saphenous venectomy scar which developed after a coronary artery bypass graft(CABG). A 68-year-old male and a 62-year-old female developed acute cellulitis in the saphenous vein donor extremity after CABG. The repeated bacterial cultures were negative in both cases. However, onychomycosis was confirmed in one patient. The intervals between CABG and the initial bout of cellulitis in the male and female patient were 10 and 22 months, respectively. Although the exact pathogenesis remains obscure, factors such as direct bacterial infection, hypersensitivity to streptococcal exotoxins, a local compromise of lymphatic and venous drainage, and fungal infection might have contributed to the development of cellulitis in these patients.

BACKGROUND: The incidence of Cutaneous malignant tumors has increased recently and they have varied in their developing patterns according to social and environmental influences. However, we have little clinical data about the cutaneous malignant tumors in the Chonnam provinee. OBJECTIVE: Our purpose was to analyze the clinical characteristics of cutaneous malignant tumors observed in the Chonnam province and to compare them with the data previously reported in Korea. METHOD: We clinically analyzed 427 cases of cutaneous malignant tumors during a 10 year period betwecn January 1987 and Oetober 1996, at the Department of Dermatology, Chonnam Univemity Hospital in Kwangju. RESULTS: 1. The average armual incidence of cutaneous malignant tumors among the total number of outpatients was 1.00+/- 0.25%. The incidence tended to increase with time from 0.90+/-0.29% in the first 5 year-period to 1.15+/-0.09% in the late 5 year-period. The increasing rate was most pronmient in basal cell carcinoma. 2. The most common tumor in the 427 patients with malignant tumor was basal cell carcinoma (52.5%), followed by squamous cell carcinoma (19.9%), malignant melanoma (13.3%), metastatic carcinoma (3.7%), malignant lymphoma (2.3%). 3. The mean age of onset was 60.7+/-16.0 years old (male; 59.6+/-15.0, female; 61.9+/-17.1) in the in the group as a whole; 63.9 in BCC, 63.3 in SCC and 55.8 in malignant melanoma. The ratio of men to women was 1.14:l. 4. The most common site of a11 malignant tumors was the head and neck (64.6%), where 89.3% of BCC, 58.8% of SCC, and 15.8% of malignant melanoma developed. The next common site was the lower exlremities and feet (15.7%) followed by the trunk (7,7%), and upper extremities and hands (7.3%).

Intramedullary myelitis due to bacterial meningitis associated with cervical epidural abscess is very rare. Its cause and clinical features are non-specific, therefore exact diagnosis is often missed or mistaken for other disease and immediate treatment may be delayed. We report a case of intramedullary myelitis due to epidural abscess presented with prominent symptoms of meningitis and manifestations of acute cerebrovacular accident. A 69 -year-old man was admitted due to right hemicranial headache with pain on right posterior neck and febrile sensation. At first, the patient's headache was improved by conservative therapy. Three weeks later, the patient showed abrupt right hemiparesis (MRC grade 2/5) with drowsy mentality. The CSF findings of the patient were compatible with acute bacterial meningitis. Cervical spine MRI showed cervical epidural abscess and extensive intramedullary myelitis from cervical to lumbar spinal cord. After antibiotic therapy, mentality of the patient became to be alert and right hemiparesis was improved to MRC grade 4/5. Follow up cervical spine MRI after several weeks represented that the lesions of cervical epidural abscess and intramedullary myelitis were significantly diminished.
