OBJECTIVES: Several studies have shown that performance related musculoskeletal disorders present a significant and common health problem for instrument players. This study was conducted to investigate the symptom prevalence rate of performance-related musculoskeletal disorders and risk factors on symphony orchestra players. METHODS: The symptom prevalence rate of musculoskeletal disorders and related factors including demographic factors, occupational factors, psychosocial factors, practice and performance-related behaviors of on 156 symphony orchestra players in Taegu city were surveyed with a self-administered questionnaire. RESULTS: Instrument players have performed for 14. 6 years in average and worked 4. 9 for years in average as a member of symphony orchestra. The subjects consisted of 106 string players, 48 wind players, and 8 percussion players. The symptom prevalence rate of musculoskeletal disorders according to the NIOSH surveillance criteria was 79. 6 % and operational criteria by authors was 45. 9 %. The prevalence rate of viola players was higher than violin players, and the prevalence rate of the bass players was higher than that of the cello players. In univariate analysis, job insecurity, irregular performance, stress from family problems, and performance related psychosomatic strains had a significant association with the prevalence rate of musculoskeletal disorders. In multiple logistic regression, job insecurity, irregular performance, and stress from family problems were significant variables affecting the prevalence rate of musculoskeletal disorders of instrument players. CONCLUSIONS: This study suggest that symphony orchestra players are high risk group of musculoskeletal disorders. Irregular performance schedule and psychosocial stress including job insecurity, and psychosomatic strain were important risk factors of players musculoskeletal disorders. An exercise program such as stretching before and after performance, regular performance schedule and reduction of psychosocial stress might be helpful for prevention of musculoskeletal disorders of instrument players.

BACKGROUND: Induction of anesthesia with propofol commonly associated with reduction in systemic arterial pressure, especially in elderly and high risk patients. This reduction is influenced by the dose and rate of propofol injection. The aim of this study was to examine the effect of different injection rate of propofol on vital signs, dose requirement and induction time during induction period. METHODS: Unpremedicated one hundred and twenty ASA physical status I and II patients aged 20~60 years scheduled for elective surgery were randomly allocated into one of four (150, 300, 600, 1200 ml/hr) groups according to speed of injection of propofol during induction period. Loss of verbal contact was taken as the end-point of induction. Vital signs, SpO2, dose requirement of propofol and induction time were checked. RESULTS: As the injection rate of propofol became slower, there were significant reduction in induction dose and increase in induction time (p<0.05). For example, induction dose and time were 1.82 mg/kg, 223 +/- 58 sec in 150 ml/hr group and 3.14 mg/kg, 50 +/- 11 sec in 1200 ml/hr group, respectively. Also, decrease in systolic and diastolic pressure were less marked at lower injection rates. CONCLUSIONS: Slower injection of propofol produces less vital sign changes and dose requirement for the induction of anesthesia.

Clinical studies were made on 50 cases of chronic cough infants who were admitted to the department of Pediatrics of Kangnam St. Mary' s hospital from January, 1990 to July, 1991. The results were as follows; 1) The age distribution was from 3 months to 24 months old, and the most prevalent age group was 13~18months old. The male to female was 2.1:1. 2) The etiologic classification of the 50 cases were infantile asthma in 23 cases(46%), viral lower respiratory infection in 13 cases(26%), and infantile asthma associated with sinusitis in 5 cases(10%). 3) Cough was the most common clinical manifestation in all cases and followed by rhinorrhea, dyspnea, fever, and nasal stuffiness. Among physical findings, wheezing rales, and chest retraction were noted. 4) The duration of cough was 5 to 8 weeks in 26 cases(52%), 2 to weeks in 19 cases(38%), and above 9 weeks in 5 cases(10%). 5) 13 of 50 cases had a past allergic history and 8 of 50 cases had a family history of allergy. 6) In 50 cases, formula feeding was done in 28 cases(56%), breast feeing in 13 cases(26%), and mixed feeding in 9 cases(18%). 7) Eosinophilia was noted in 39.3% of infantile asthma and total IgE level above 100IUm/ml was noted in 60.7% of infantile asthma and in 18.2% of other diseases. 8) RAST results of infantile asthma showed that the positivity was 21.4% in house dust, 32.1% in Dermatophagoides pteronyssinus, 28.6% in Dermatophagoides farinae, 28.6% in egg white, 35.7% in milk. The ratio of positive RAST results were higher in infantile asthma than in other diseases. 9) Abnormal findings, including overinflation, infiltration, increased bronchovascular marking, and atelectasis, were noted in 42 cases(84%) on chest X-ray. In 7 cases, total opacification was noted on Waters' and Caldwell's view. In conclusion, chronic cough in infancy is best managed by determining the precise cause of the cough, then specificially treating the underlying disorder.

Melkersson-Rosenthal syndrome (MRS) is a rare form of hereditary angioedema characterized by a triad of orofacial swelling, relapsing facial paralysis, and a fissured tongue. However, the classic triad is not frequently seen in its complete form, and monosymptomatic or oligosymptomatic forms are more common. Case: A 20-year-old man presented with recurrent labial swelling 9 months ago and recently with a fissured tongue. The surface of the tongue showed deep furrows characteristic of lingua plicata, and an edematous enlargement was observed on the lower lips. Upon neurologic examination, a left sided facial palsy of a peripheral type was noted without abnormalities in the taste sense or lacrimation. An electromyography of the left frontal muscle showed positive sharp waves and fibrillation potentials. Biopsies performed on the lower lips revealed the congested vessels and perivascular inflammatory cells. We report a 20-year-old man with a classical triad of symptoms of Melkersson-Rosenthal syndrome.

An analytic study on 431 cases of cardiac conduction disturbance has been made by review of the clinical records and electrocardiograms taken from the adult patients registered at Kyung Hee University Hospital for 3 years from May, 1973 to April, 1976. 1. The total incidence of conduction disturbance was 6.50%, the atrioventricular block 3.14% and the intraventricular block was 3.36% of total 6,616 cases of E.C.G. reviewed. Among of these, the first degree atrioventricular block was 3.02% which was the most common occurred one, the incomplete right bundle branch block was 2.25% and the complete right bundle branch block was 0.57%. 2. The ratio of male to female was 1.6:1 for the first degree atrioventricular block, and 1.6:1 for the incomplete right bundle branch block, 2.5:1 for the complete atrioventricular block, 2:1 for the left bundle branch block, and 1.7:1 for the complete right bundle branch block. The first degree atrioventricular block was seen most frequently in the fifth and sixth decade of age group, and the third degree block was over 40 years. The incomplete right bundle branch block in order was forth decade, third decade and fifth decade. The complete right bundle branch block and left posterior hemiblock were common in the sixth decade. The left bundle block and the posterior hemiblock were common in fifty years of age group. 3. The cardinal underlying diseases of the first degree atrioventricular block among cardiac diseases group in order of frequency were: hypertensive heart disease (25.0%) arteriosclerotic heart disease (8.0%) and rheumatic valvular heart disease (5.0%). The most common etiology of those non-cardiac disease group was neuropsychiatry disorder (11.5%) and the next was infection (11.0%). 4. All of the complete atrioventricular block were associated with the cardiac disease, that is, 57.0% with arteriosclerotic heart disease, 28.5% with pericarditis and 14.3% with hypertensive heart disease, respectively. 5. The cardinal underlying disease of the incomplete right bundle branch block in order of frequency were: hypertensive heart disease (10.7%), arteriosclerotic heart disease (8.1%) among the cardiac disease group, and infections (15.4%) among the non-cardiac disease group. The incidence of healthy persons was 14.1%. 6. Those of complete right bundle branch block in order of frequency were: arteriosclerotic heart disease (13.2%), and hypertensive heart disease (10.1%) among the cardiac disease group, and infection(13.2%) and neurosis (10.1%), respectively among the non-cardiac disease group. 7. The major etiologies of the left bundle branch block was hypertensive heart disease and arteriosclerotic heart disease (33.3% each), and that of left posterior hemiblock was showed arteriosolerotic heart disease and cor-pulmonale. The most common etiological disease of the left anterior hemiblock was hypertensive heart disease in cardiac disease group, and infection and gatrointestinal disease in non-cariac disease group. 8. The abnormal electrocardiographic findings with the first degree atrioventricular block were left ventricular hypertrophy (24.8%), sinus tachycardia (11.0) and sinus bradycardia (5.8%). Those with the complete atrioventricular block were right ventricular hypertrophy (15.8%) and left bundle branch block (15.8%). In complete right bundle branch block, the majority (52.5%) showed single sign without other abnormality on E.C.G. In the left bundle branch block, there were 18.9% of left ventricular hypertrophy and 15.7% of first degree atrioventricular block. In the left anterior hemiblock, there were 28.5% of right bundle branch block, and 19.0% of right ventricular hypertrophy. In the left posterior hemiblock, there were 40.0% of atrial fibrillation and 20.0% of left atrial hypertrophy.

PURPOSE: To report a case of primary extramedullary plasmacytoma which is rare in the orbit. METHODS: A 72 year-old man was referred for the evaluation of a slowly developing proptosis in the right eye. A CT scan revealed the orbital mass which involved optic nerve and surrounding tissues. Incisional biopsy via lower lid was performed. RESULTS: Histopathologic examination confirmed the findings of plasmacytoma. Systemic evaluation including bone marrow biopsy, clinical and radiologic evaluation showed no evidence for multiple myeloma. Taken together we diagnosed the orbital lesion as a primary extramedullary plasmacytoma. He was treated with radiation therapy and followed for 6months without evidence of new lesion or systemic disease. CONCLUSIONS: We experienced a case of primary extramedullary plasmacytoma which is rare in the orbit. Continuing careful observation is warranted because of its variable natural course and prognosis.
