Myxoma is a benign mesenchymal neoplasm that can occur in the head and neck. Laryngeal myxoma is extremely rare and easily confused with a laryngeal polyp. The common clinical presentation is hoarseness, dysphonia, dyspnea and dysphagia depending on their size and location. Treatment for laryngeal myxoma is complete surgical excision with surrounding normal tissue. To our knowledge, 11 laryngeal myxomas have been reported in the English literature, and all patients except only 1 case were male. We report the second female case of myxoma on a vocal cord with a review of literature.

Background: To evaluate the effect of thoracic mobility exercise and deep breathing exercise applied to stroke patients on pulmonary function. Methods: The subjects were divided into two group. Twenty-five patients with stroke were randomly assigned to DB (deep breathing exercise) group (n=13) and TM (combination of deep breathing exercise and thoracic mobility exercise) group (n=12). During four weeks, DB group were carried out deep breathing exercises for 5~10 minutes twice a day and TM Group were carried out deep breathing exercises for 5~10 minutes and thoracic mobility exercise for 20~30 minutes twice a day. All tests were completed before and after experiment. The pulmonary functions were measured by PowerBreathe K5 (Hab International Ltd, England) and tape measure respectively. For each case, the experimental data were obtained in 4 items; average of inspiratory load, inspiratory flow speed, inspiratory flow volume and chest expansion. Results: The results of this study were as follows: 1. In DB group, the statistically significants were shown on average of inspiratory flow speed, inspiratory flow volume and chest expansion (p<.05). 2. In TM group, the statistically significants were shown on all items (p<.05). 3. There was a statistically significant difference on all items between DB group and TM group (p<.05). Conclusions: The above results revealed that DB and TM group can be used to improve pulmonary function in stroke patients. In comparison of DB and TM group, TM group was more improved. In conclude, thoracic mobility exercise helped improving function of vital capacity and chest expansion in stroke patients.

Syringomas are common benign adnexal tumors, probably of the eccrine origin. They are more common in women and usually found around the eyelids. An exclusively acral site of the lesions is very rare. We present a case of acral syringomas in a 44 year-old woman, involving only the dorsum of the fingers of both hands. It is important to include syringomas in the clinical differential diagnosis of papular lesions of the hands. (Korean J Dermatol 2012;50(5):440∼442)

Pyoderma gangrenosum (PG) is a rare and painful skin disease, frequently associated with underlying systemic conditions, such as inflammatory bowel disease or hematological malignancy. PG is generally classified into 4 types: classic (ulcerative), bullous, pustular, and vegetative. Pustular PG is an uncommon variant of PG that the pustules do not progress to form ulcers. We report a case of pustular PG, which was successfully treated with infliximab and topical tacrolimus, in a 28 year-old Korean man with ulcerative colitis. (Korean J Dermatol 2012;50(12):1050∼1053)

Background: Ultrasonography is an important diagnostic tool for many aspects of clinical medicine. It is a non-invasive method of examination that provides high-resolution images in real time. However, some dermatologists may be anxious about the efficacy of ultrasonography. Objective: To evaluate the diagnostic accuracy and to assess the utility of diagnostic ultrasonography for subcutaneous benign lesions. Methods: The study included 96 patients with subcutaneous benign lesions who underwent ultrasonography and then received a pathologic diagnosis after biopsy or surgery at our hospital from July 2010 to December 2012. This study evaluated the number of cases in which the preoperative diagnosis after ultrasonography or just after physical examination agreed to the pathologic diagnosis. Results: Ultrasonography significantly increased the diagnostic yield of subcutaneous benign lesions (after physical examination, 54.2%; after ultrasonography, 84.4%; p<0.001). The sensitivity for the diagnosis of lipoma (after physical examination, 70%; after ultrasonography, 92.5%; p<0.001) and the specificity for the diagnosis of epidermal cyst (after physical examination, 84.1%; after ultrasonography, 94.2%; p<0.001) significantly increased after ultrasonography. The sensitivity for the diagnosis of epidermal cyst and pilomatricoma also tended to increase after ultrasonography. Conclusion: The study results suggested that ultrasonography is useful for diagnosis and/or preoperative examination of subcutaneous benign lesions.

본 연구는 등받이 유무에 따른 하지 운동프로그램이 허리통증이 있는 대학생에게 미치는 영향을 알아보기 위해 균형능력, KODI, VAS 검사를 이용하였다. 광주광역시 소재 K대학교 학생 32명을 대상으로 4주간 탄력밴드를 이용한 하지 운동프로그램을 진행하였으며 등받이의 유무에 따른 집단 별 16명씩 무작위로 선정하여 진행하였다. 균형능력과 KODI 점수에서는 집단과 시간에 의한 상호작용이 없는 것으로 나타난 반면 VAS 점수에서는 집단과 시간에 의한 상호작용이 나타났다. 또한 두 집단 모두 중재 후에 균형능력, KODI, VAS 점수에서 유의하게 증가하였다. 따라서 등받이 유무와 상관없이 의자에 앉아서 시행하는 하지운동 프로그램이 오랜시간 앉아서 생활하며 허리통증이 있는 학생과 직장인에게 일상에서 쉽게 할 수 있는 운동 프로그램으로 적용하는 것이 필요할 것으로 생각된다. This study was conducted on college students with low back pain to find out how a backrest exercise program affects the pain and balance of students. Thirty-two students at K University in Gwangju City were randomly classified with backrests and without backrests group respectively. Each group conducted the program for lasted three times a week for a total of 30 minutes for four weeks. Visual Analog Scale (VAS) was measured for pain assessment before and after arbitration, and the Korean Oswestry Disability Index (KODI) was measured for functional disability assessment. TETRAX is used to measure the weight distribution index and posture stability. According to the results of the experiment, the Visual Analog Scale (VAS) and the Korean Oswestry Disability Index (KODI) and weight distribution index showed significant differences over time, but the posture stability was no significant difference. The results of this study show that the lower limb exercise program is effective in back pain, dysfunction and weight distribution index, and it is believed that the pain reduction is significant when performed by distal movement in the area of back pain, It can be applied effectively to reduce low back pain in college students who spend a lot of time sitting down.
