Malignant fibrous histiocytama is currently defined as a malignant primary bone tumor, and that may contain fibromatoua, xanthomatous, or histiocytic elementa, varing widely in the degree of anaplasia that is present. The principal lesions to be considered in the differential diagnoais of malignant fibrous histiocytoma are osteogenic sarcoma and fibrosarcoma. Malignant fibrous histiocytoma is more sensitive to chemotherapeutic ageata than are osteosarcama and fibrosarcama. In this paper 2 cases sre reported, including the one in which the tumor arose in a midahaft of the femur and the other one arosein the upper metaphyseal portion of the tibla.

Treatment of unstable cervical spine fracture by skull traction is time consuming procedure, and treatment by Halo appratus has many advantages but it is very expensive. Bone cement has been applied occasionally as an adjunct to metallic internal fixation in treating patient with malignancy, i.e. limited life expectancy. Internal fixation with bone cement in addition to routine posterior fusion with bone graft is tried eliminate the need of application of complicated external immobilization in treating unstable cervical spine fracture of young patient. We experienced two cases of posterior cervical fusion using bone cement with satisfactory results. The advantages of this method are: 1. Rapid and solid fixation 2. Early ambulation 3. Reduce complicated external support 4. Reduce the date of hospitalization.

Primary uterine leiomyosarcomas are very rare malignant tumors and the related MR findings have been the subject of only a few case reports. We describe the MR findings of two cases of histologically confirmed primary leiomyosarcoma, correlating these pathologic findings.

OBJECTIVE: International institutes such as Global institute for Asthma(GINA), KAAACI(Republic of Korea), NHLBI(USA), BTS(UK) and JSA(Japan) have published guidelines for asthma treatment. The aim of this study was to compare the representatives' international guidelines of pharmacotherapy for pediatric asthma. METHODS: The recommendations related to pharmacotherapy for pediatric asthma were extracted from the latest representatives' international guidelines, and comprehensive comparisons were conducted. RESULTS: Major comparison outcomes between international guidelines were evaluated as follows: classification system on severity and pediatric age group, recommendation for inhaled corticosteroid dose, recommendation for pediatric age group of theophylline in mild asthma, and recommendation for pediatric age group of tiotropium in severe asthma. Clinical trials emphasized the adverse effects of theophylline, whereas tiotropium demonstrated beneficial actions for pediatric asthma. Therefore, theophylline was recommended for older patients with persistent asthma, and tiotropium was considered to be suitable for younger patients with severe asthma according to GINA guidelines. CONCLUSION: These findings address the requirement to harmonize international guidelines of pharmacotherapy in pediatric asthma. In addition, the findings suggest that KAAACI needs to update its pharmacotherapy guidelines of theophylline, tiotropium and other medicines recently approved.

OBJECTIVES: To determine the prevalence and related factors of work related musculoskeletal symptoms in hairdressers. METHODS: Informations on general characteristics, job strain, and musculoskeletal symptoms were obtained by a self-administered questionnaire, through adopting NIOSH instrument and JCQ(Job content questionnaire), from 267 hairdressers, between March and May, 2000. RESULTS: The symptom prevalence by NIOSH surveillance criteria in total was high as 94.4%; shoulder (61.0%), neck (59.9%), low back (53.2%), hand and wrist (41.6%), etc. In multiple logistic regression, significant factors affecting the symptoms by body region; job insecurity on neck' gender, alcohol, decision latitude on low back; alcohol on hand and wrist; smoking on thigh and knee,' smoking, decision latitude on ankle and foot; job insecurity on upper back. CONCLUSIONS: Musculoskeletal symptoms of hairdresser were highly prevalent, and associated with job strain and their health habits. This is a basic data of work related musculoskeletal disorders among hairdressers who are not the subjects of occupational health service at the present time in Korea.

PURPOSE: The purpose of our study was to identify the CT findings that help detect pleural dissemination from lung cancer and to evaluate the usefulness of selected diagnostic criteria. MATERIALS AND METHODS: After a computerized database search of 606 patients who had undergone thoracotomy for primary lung cancer, 23 patients were identified as h aving surgically documented pleural dissemination. From the same database, 50 patients without pleural dissemination during thoracotomy were randomly selected as controls. Preoperative CT scans and medical records were rev i ewed retrospectively, and findings were compared between the two groups. RESULT: One or more of three types of pleural thickening (plaque-like, nodular, and fissural) were identified on CT as the most discriminating finding (sensitivity, 74 % ; specificity, 60 %; p = 0.007). The following findings were also significantly discriminating (p<0.05): contiguity of primary tumor with the pleural surface as seen on CT; adenocarcinoma in cell type; and a peripheral tumor defined as one in which bronchoscopy revealed no endobronchial lesion. The use of combinations of these findings in addition to pleural thickening rendered diagnostic criteria more specific at the cost of the sensitivity. CONCLUSION: During preoperative CT evaluation of lung cancer, the recognition of subtle pleural thickening helps detect pleural dissemination. The likelihood that subtle pleural thickening represents pleural dissemination is increased when a primary tumor is contiguous with the pleural surface, is an adenocarcinoma, or is peripherally located.

Invasive aspergillosis is a life-threatening infectious disease in immunocompromised patients. Aspergillus is an ubiquitous mold present as normal flora in paranasal sinus, nose, skin and lung. The most important determinant of infection is the immune status of the patient, not the intensity of exposure. In acute leukemia and bone marrow transplantation, prolonged neutropenia is probably the most important predisposing factor. We experienced a case of invasive aspergillosis involving lung and brain in patient with acute leukemia during remission-induction chemotherapy. Invasive aspergillosis involving lung and brain was diagnosed by sputum culture, computed tomography (CT) guided lung biopsy and brain magnetic resonance imaging (MRI). Early diagnosis and prompt treatment for invasive aspergillosis are essential for lowering mortality in immunocompromised patients.

Primary lymphoma of the central nervous system is a rare disease, occurring spontaneously and/or in conjunction with immunosuppressive state. Its incidence is increasing according to the increment of organ transplantation and AIDS. Recently we experienced a case of primary lymphoma occurred in central nervous system after renal transplantation in a 58-year-old women who had complained of persistent headache and left hemiparesis. CT scan of the brain showed two hyperdense mass lesions in right frontal and right basal ganglia areas. Immunohistochemical stain of the excised mass lesion revealed that tumor cells were derived from B cells. The patient was treated with discontinuance of immunosuppressive drug and irradiation, but expired due to pneumonia.

A 68-year-old man with small cell carcinoma of the lung and adenocarcinoma of the prostate underwent Tc-99m MDP bone scintigraphy for the evaluation of skeletal metastases. Bilateral symmetrical photon defects in both parietal bones of the skull were observed. The radiographs of the skull demonstrates biparietal thinning in the same area of the abnormality identified on bone scintigraphy. Although these findings in cancer patients can be mistaken for skeletal metastases, the symmetry and location of the photon defects are generally indicative of biparietal thinning.
