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.

Tricho-rhion-phalangeal syndrome is characterized by the triad of slow growing, brittle hair and early loss of hair, distinctive faces which include a long philtrum and pear-shape nose, and peripheral cone shape epiphysis with brachyphalangia. Tricho-rhion-phalangeal syndrome is probably not so much uncommon. The tricho-rhion-phalangeal syndrome, however, is not well recognized to orthopaedic surgeons due to the minor finger deformities. We report a case of tricho-rhion-phalangeal syndrome with brief review of literature.

Heterotopic pregnancy is the coexistency of intrauterine and extrauterine pregnancy. The incidence of heterotopic pregnancy is about 1 to 30,000 pregnancy in a natural cycle. However, the frequency of heterotopic pregnancy has steadily increased because of rising incidence of pelvic inflammatory disease, pelvic surgery and the development of ovulation induction and assisted reproduction. Because heterotopic pregnancy is difficult to diagnose and it has high morbidity and mortality rate, one should always take this into consideration and should conduct careful and thorough gynecologic evaluation. We have experienced a case of heterotopic pregnancy in a 29-year old woman who presented with acute abdominal pain in a natural cycle and report this case with a brief review of literature.

Purpura fuIminans is a rare form of nonthrombocytapenic purpura characterized by sudden onset, fever, prostration, anemia and symmetrical massive ecchymoses, usually of the lower extremities, and hypotension associated with disseminated intravascular coagulation (DIC). A 18 years old female patieat with characteristic clinical manifestations of purpura fulminans was seen at the department of Dermatology, St. Pauls Hospital. With intensive systemic corticasteroid and heparin treatmemts, the ecchymoses and necrosis began to heal, leaving multiple, thick esehar formation from 8th day, Although purpura fulminana has been known to attack mainly children, this case was of adolescent age.

OBJECTIVES: A cross sectional study was carried out in the welders exposed to manganese and control group. The aim of this study was to assess the adverse effects of manganese on central nervous system of welders. METHODS: The study group consisted of 49 welders and the reference group, 49 workers matched with welders for age and educational level in automobile manufacturing company. Concentration of manganese in welding hume, in blood, and cumulative exposure index(CEI) were determined for each subject. For each group, computerized neurobehavioral test including Simple Reaction Time, Digit Symbol, Digit Span, and Finger Tapping Speed of Swedish Performance Evaluation System were applied. RESULTS: Exposure level of manganese in welders were very low(mean CEI 0.069). Welders exposed to manganese had slower response speed, slower motor steadiness, and shorter memory span than control group. But these differences were not statistically significant. The performance of Finger Tapping Speed tended to lower as environmental and biological exposure index got higher. Other neurobehavioral tests were found to have a little association with the exposure indices. CONCLUSIONS: There was no significant difference of neurobehavioral performance between welders and control group. This study indicates that Finger Tapping Speed measuring motor steadiness might be a one of useful tests for early detection of adverse effects of welding on central nervous system.

It is the purpose of this experimental study to investigate the alterations of the amount of adenosine nucleotides and adenylate energy charge in the acute focal cerebral ischemia of cats utilizing high performance liquid chromatography and to make a comparative study of protective effects of recirculation and combined therapy with mannitol, steroid and barbiturate. Acute focal cerebral ischemia in cats was induced by occlusion of the left middle cerebral artery through the postorbital technique. The experimental animals were divided into four groups according to the duration of occlusion time. The experimental results are obtained as follows: 1) In 1, 3 and 5 hour-occlusion groups, amount of adenosine triphosphate and summation of adenosine nucleotides decreased significantly to 21.4%, 5% & 0%, 44.0%, 29.9% & 10.8% of the sham control, respectively. Also in these groups adenylate energy charge decreased significantly to 62.7%, 38.7% and 30.7% of the sham control, respectively. It was suggested that the longer duration of occlusion time was, the more amount of adenosine triphosphate, summation of adenosine nucleotides and adenylate energy charge decreased significantly. 2) In 1 and 3 hour-occlusion groups, 2 hour-recirculation increased significantly amount of adenosine triphosphate and summation of adenosine nucleotides to 37.4% & 29.4%, and 62.1% & 58.3% of the sham control, respectively. Also in these groups recirculation increased significantly adenylate energy charge to 70.7% and 65.3% of the sham control, respectively. Whereas there was a slight increase of adenylate energy charge after recirculation in 5 hour-occlusion group, but not significant. 3) In the groups of recirculation following 5 hour-occlusion, pretreatment of combination of mannitol and steroid, or mannitol, steroid and barbiturate increased significantly amount of adenosine triphosphate, summation of adenosine nucleotides, and adenylate energy charge to 57.2% or 66.1%, 80.9% or 83.5% and 82.7% or 84.0% of sham control, respectively.

A man with bilateral primitive persistent trigeminal artery combined with cerebral rete mirabile is reported. Direct both common carotid artery angiogram is described with a brief discussion of the embryogenesis of carotid-basilar anastomosis and cerebral rete mirabile. Associated findings of previously reported cases of persistent trigeminal artery and cerebral rete mirabile are briefly reviewed. Persistent of the bilateral trigeminal artery associated with hemorrhage from cerebral rete mirabile seems worthy of notation. The angiographic findings were as follows; 1) The characteristic angiographic findings are bilateral occlusion at the cavernous portion of internal carotid artery. 2) Retrograde filling of middle cerebral artery from the collateral anastomotic channel was showed. 3) Anterior and posterior cerebral arteries are filled from leptomeningeal anastomotic channel and cerebral rete anastomosis. Authors suggested that the persistent trigeminal artery is congenital origin and cerebral rete mirabile may suspect to the secondary change.
