Intramuscular myxoma (IM) is a benign neoplasm of mesenchymal origin. We report a rare case of IM which was located in the lumbosacral paraspinal muscles. A 62-year-old female patient presented with progressive low back pain for 2 months, and the radiologic findings showed a large mass ($4.0{\times}3.5{\times}6.5cm$) in the right lumbosacral paraspinal area. Total resection of the tumor was performed and the symptom was nearly resolved after surgery. Although the immuno-histopathological analysis was consistent with IM, there were some different findings from typical pathological characteristics of IM in this case. Firstly, the symptomatic change of the mass took relatively short time (less than 3 months), and this change was accompanied by partial calcification inside the mass. Moreover, iatrogenic interruption of paravertebral muscle by the other previous operation might be the promoting factor of the fibrous dysplasia, which can explain the pathogenesis of IM. To our knowledge, this is the eighth case of the lumbar paraspinal myxoma reported in the literatures and the first case in Asian population.

The purposes of this study are to compare data for work-related musculoskeletal disorders(WMSDs) between Korea and USA, and to investigate status of WMSDs for industrial safety managers. The first part of this study was based on statistical data annually published by Minister of Labor of Korea and Bureau of Labor Statistics of USA. The latter was performed by using questionnaire survey for industrial safety managers in two regions. The results showed that the WMSDs incidence rate was significantly lower in Korea than in USA, and that there is big difference in the distribution of occupational illness by category of illness between Korea and USA. The questionnaire survey revealed that knowledge level about WMSDs was significantly affected depending upon corresponding companies' location and size, and that the low back pain was the most prevalent illness among varying WMSDs symptoms, followed by tendonitis/tenosynovitis, carpal tunnel syndrome, and tennis elbow. Based on this study, it is recommended that the future education/training for WMSDs focus on their preventative measures, methods/tools for identifying their risk factors, and diagnostic criteria for judging suspicious symptoms for industrial accidents, and that the governmental policy for WMSDs be changed towards financial supporting for preventive facilities, establishing objective diagnostic criteria and training for WMSDs.

Objectives : This study was designed to evaluate the effects of Bee Venom Pharmacopuncture therapy in patients with lumbar spinal stenosis. Methods : We investigated 16 patients with lumbar spinal stenosis. We divided patients into two groups : Bee Venom Pharmacopuncture was performed with acupuncture therapy for one group, and the other group received acupuncture therapy only. To evaluate the effectiveness of the treatment applied to the two groups, we used the Visual Analog Scale(VAS) and the Oswestry Low-back Pain Disability Index(ODI). We compared the VAS and ODI scores of the two groups statistically. Results : The Bee Venom Pharmacopuncture group received more effective relief than the acupunctureonly group as measured by decreasedpain and disability reported on the VAS and ODI by patients with lumbar spinal stenosis. Conclusions: Bee Venom Pharmacopuncture therapy can be used in addition to acupuncture therapy for highly effective treatment of patients with lumbar spinal stenosis. Further clinical studies are needed to verify these findings.

Chordoma is relatively uncommon tumor comprising $1\sim4%$ of primary malignant bone tumors, and believed to arise from the remnants of notochordal tissue. Because of its rare occurrence in the thoracic spine, we report a case of chordoma involving the thoracic spine. A 45-year-old male was sufferred from chest pain radiating to the back. Chest CT showed a well marginated, round huge mass with multiseptated enhancement at the thoracic spine from T5 to T8 level. After percutaneous needle aspiration, piecemeal resection of the tumor was done. On cytologic smears, two types of neoplastic cells were arranged in sheets and cords in mucinous background. One type of cells consisted of medium sized cells with pink cytoplasm and round nuclei. The other type had voluminous bubbly or clear cytoplasm divided by intracytoplasmic septae imparting a feathery or basket-like appearance. Histologically, the tumor showed lobulated feature divided by fibrous septae and the tumor cells were pink eosinophilic or physaliphorous in morphology. Immunohistochemically, the tumor cells revealed strong positivity for low(AE1) and high (AE3) molecular weight cytokeratins.

In order to study the effect of the isometric exercises on the flexibility. the strength and the waist and hip circumferences, 10 female university students who aged 22.10 ${\pm}$ 1.10 years were measured by sit-up for strength, and trunk flexion test and trunk lifting for flexibility, and also measured by waist and hip circumferences before and during, and after the Swiss ball exercise program. Statistical analysis was performed using SPSS/PC WIN 7.0 version. and one-way repeated ANOVA Test, The results of the test were as shown; We found that the number of performing sit-up was increased. and the trunk flexion test and trunk lifting was increased, and the waist and hip circumferences were increased after the 6 weeks Swiss ball exercise program. These findings indicate that Isometric exercise using Swiss ball could be beneficial to the low back pain patients due to the effect of increasing strength and flexibility of the patients.

Purpose: This study was conducted to identify sexual functioning in women with gynecologic cancer. Method: Sexually active women with gynecologic cancer without evidence of distant metastasis were recruited in Seoul, Korea from a university medical center. Subjects were asked to complete an anonymous mail-back survey on their sexual functioning. Result: One hundred eighty four women completed questionnaires. Their mean age was 51.0 years and 96.2% lived with their husbands. Subjects were diagnosed with cervical cancer(53.8%), ovarian cancer (27.7%), or endometrial cancer(18.5%). Sexual functioning for women with gynecologic cancer was relatively low, 15.4, in comparison to Rosen's cutoff scores of 26.6. Univariate analyses indicated that age, employment status, and their monthly income were significantly associated with sexual functioning. Tumor staging, treatment modality, and hormone replacement therapy were also significantly associated factors with women's sexual functioning. Sexual arousal, orgasm, and pain were affected by time since last treatment. Conclusion: Sexual counselling or education for women with gynecologic cancer should be considered by medical professionals in order to improve their quality of life including sexual functioning.

Myositis ossificans (MO) is a benign condition of non-neoplastic heterotopic bone formation in the muscle or soft tissue. Trauma plays a role in the development of MO, thus, non-traumatic MO is very rare. Although MO may occur anywhere in the body, it is rarely seen in the lumbosacral paravertebral muscle (PVM). Herein, we report a case of non-traumatic MO in the lumbosacral PVM. A 42-year-old man with no history of trauma was referred to our hospital for pain in the low back, left buttock, and left thigh. On physical examination, a slightly tender, hard, and fixed mass was palpated in the left lumbosacral PVM. Computed tomography showed a calcified mass within the left lumbosacral PVM. Magnetic resonance imaging (MRI) showed heterogeneous high signal intensity in T1- and T2-weighted image, and no enhancement of the mass was found in the postcontrast T1-weighted MRI. The lack of typical imaging features required an open biopsy, and MO was confirmed. MO should be considered in the differential diagnosis when the imaging findings show a mass involving PVM. When it is difficult to distinguish MO from soft tissue or bone malignancy by radiology, it is necessary to perform a biopsy to confirm the diagnosis.

The vast majority of schwannomas occur on cranial nerves, and rarely in the retroperitoneum. Solitary schwannoma in the psoas muscle is extremely rare. The authors present a case of retroperitoneal neoplasm in the psoas muscle identified as schwannoma which is not associated with von Recklinghausen's disease. A 68 years old female patient was admitted because of low back pain and weakness at the left leg. CT and MRI revealed a large cystic mass with well-defined margin and multiple internal septation within the left psoas muscle. The tumor was totally extirpated and histologically confirmed as a schwannoma.
