Objective: There are many types of exercises with upper and lower-limb action for activation of abdominal muscles for trunk stabilization. A comparison of the different exercise methods been very useful to enhance the result from the exercise for treatment. The purpose of this study was to investigate through surface electromyography (EMG) the changes in abdominal muscle activity during the performance of three different dead-bug exercise methods performed at three different speeds. Design: Cross-sectional study. Methods: The subjects were 30 healthy adults (13 males and 17 females). We instructed the subjects to perform three different dead-bug exercises. We also applied three different speeds to the dead-bug exercises; 60 bpm, 90 bpm, and 120 bpm with use of a metronome. The assessment of EMG was percentage of maximal voluntary isometric contraction on the rectus abdominis (RA), external oblique (EO), and internal oblique (IO). Results: EMG activation of the RA, EO and IO muscles was significantly greater at the higher speed (p<0.05). There was a significant increase in abdominal muscle activity during the dead-bug exercise performed with both the upper and lower extremities compared to that with only the upper extremity or the lower extremities (p<0.05). Conclusions: These findings demonstrate that the performance of the dead-bug exercise with both the upper and lower extremities combined at a high speed is more effective compared to other exercises. Therefore, it is suggested that more favourable and effective outcomes may occur when the type and speed of the exercise is chosen appropriately.

Multiple symmetric lipomatosis (MSL) is a rare disease characterized by symmetrical massive fatty deposits on the face, neck, shoulders, and upper trunk. We report a 74-year-old man who complained of painless subcutaneous nodules on his posterior neck that developed 3 weeks earlier. In a week, variably-sized similar lesions developed on both his shoulders and upper extremities. At the time of his hospital visit, several firm nodules as big as a walnut to a child's fist and with the normal-skin-hue were observed on his posterior neck, both shoulders, upper extremities, and trunk. The histological examination of his upper left arm revealed more mature adipocytes without encapsulation in the subcutaneous tissue. MSL was generally known to occur slowly over months or years. However, this is an unusual case that showed a fast-growing nature.

The advent of free bone flaps has made successful replacement of extensive areas of bone loss in the upper and lower extremities. The microvascular free bone flaps have faster healing without bony absorption or atrophy and can heal in the hostile environment of scarred bed or infection. Since the fibula free flap introduced by Taylor and colleague in 1975, it has been used extensively for skeletal reconstruction of extremities. In 1988, the folded vascularized fibula free flap was first described as a technique to reconstruct significant long bone defect of upper and lower extremities. During the same time, the fibular free flap has evolved to become most preferred choice of mandibular reconstruction. Up to present day, few reports have been made on the fibular free flap used for reconstruction of injured hand containing metacarpal bone and soft tissue defect. We present here our new and unique experiences with vascularized fibular osteocutaneous free flap as useful and satisfactory one for reconstruction of hand with composite defects.

Midaortic syndrome (MAS) is a rare vascular disease that commonly causes renovascular hypertension. The lumen of the abdominal aorta narrows and the ostia of the branches show stenosis. MAS is associated with diminished pulses in the lower extremities compared with the upper extremities, severe hypertension with higher blood pressure in the upper rather than lower extremities, and an abdominal bruit. The clinical symptoms are variable, and recognition in children with hypertension can aid early diagnosis and optimal treatment. Hypertension with MAS is malignant and often refractory to several antihypertensive drugs. Recently, radiologic modalities have been developed and have led to numerous interventional procedures. We describe the case of a 3-year-old boy presenting with left ventricular hypertrophy whose severely elevated blood pressure led to the diagnosis of idiopathic MAS. This case highlights the importance of measuring blood pressure and conducting a detailed physical examination to diagnose MAS. This is the first reported case of idiopathic MAS diagnosed in childhood in Korea.

Kaposi's sarcoma (KS) is a cancer that causes patches of abnormal tissue to grow under the skin. It also occurs in the immunosuppressive population. KS is currently believed to be caused by infection with human herpes virus-8 (HHV-8) in non-human immunodeficiency virus patient. A 79-year-old female visited the outpatient clinic presenting with increasing number and size of palpable masses on both upper and lower extremities. She was first diagnosed as drug-erupted dermatitis and stopped her medications, but the symptoms got worse. We did partial biopsy, and KS with HHV-8 was diagnosed histopathologically. She planned to undergo further evaluations and proper treatments. This rare case suggests the need to consider a classic type of KS in the differential diagnosis of specific dermatologic symptoms such as macular, nodular, and darkish patches of upper or lower extremities in elderly patients. It is believed that this case helps to strengthen awareness of this rare disease.

Objectives : This study was purposed to estimate prevalence of upper extremity musculoskeletal symptoms, level of occupational stress and their relationship among dental hygienists. Methods : This questionnaire study was performed during May to October 2010 with 317 dental hygienists worked in Busan and Gyeongsangnam-do recruited as study population. The occupational stress and upper extremity musculoskeletal symptoms were accessed using questionnaire of the Korean Occupational Stress Scale and musculoskeletal symptoms from the Korea Occupational Safety Health Agency. Data analysis was performed with the descriptive analysis, chi-square test, and multiple logistic regression analysis using SPSS(ver 19.0K)program. Results : The prevalence of upper extremity musculoskeletal symptoms and the level of occupational stress were 79.2% and $52.67{\pm}4.86$ in dental hygienists. By multiple logistic regression analysis, job insecurity(OR=2.86, 95% CI: 1.38-5.94 in stress high risk group; reference-stress low risk group) and organizational system(OR=3.32, 95% CI: 1.55-7.08 in stress high risk group; reference-stress low risk group) were associated with upper extremity musculoskeletal symptoms in dental hygienists. Conclusions : The overall prevalence of upper extremity musculoskeletal symptoms and level of occupational stress in dental hygienists were relatively high and some sub-scales of occupational stress were related with upper extremity musculoskeletal symptoms. Not only previously reported risk factors of musculoskeletal symptoms but also occupational stress should consider to prevent and improve upper extremity musculoskeletal symptoms in dental hygienists.

Schwannomas are rare and distinctive nerve sheath tumors. They occur commonly along the course of central and peripheral nerves, especially on the skin of the head, neck and extremities. Histologically, they are characterized by Antoni A and Antoni B tissues of high and low cellularity. 2 cases of intrapulmonary Schwannomas were reported worldwide by 1980. We report a case of twenty seven-year-old male patient with intrapulmonary Schwannoma, who had multiple nodules on the skin of the both upper extremities and scrotum with their characteristic findings.

Clear cell sarcoma (CCS), also called malignant melanoma of soft parts, is a rare malignant soft tissue tumor and is often associated with tendons or aponeuroses. Most of CCS involve extremities, especially lower extremities, but a tumor occurring in the trunk is rare. We report an extremely rare case of CCS originated in the upper thoracic back muscle. To our knowledge, this case is the second report of CCS of the back muscle.
