Carcinsarcoma is an uncommon pulmonary malignancy characterized by carcinmatous parenchyma and sarcomatous stroma. The cytologic, immunohistochemical and ultrastructural features of a case of pulmonary carcinosarcoma suspected by fine needle aspiration cytology is presented. Only bizarre spindle cells arranged in loose groups, in microtissue fragments and in a dissociate fashion were present in the aspiration smears. They were markedly positive for vimentin. The epithelial component was not found, which was probably due to marked paucity of carcinomatous component that was proved by histologic examination of the resected tumor. The diagnosis of pulmonary carcinosarcoma should be conidered whenever poorly differentiated epithelial cell groups with a malignant mesenchymal component set in a myxoid background are seen in a pulmonary cytology specimen.

Systemic lupus erythematosus (SLE) is a disease of unknown etiology in which tissues and cells are damaged by pathogenic autoantibodies and immune complexes. Skin manifestations of SLE include malar rash, discoid rash, photosensitivity, oral ulcer, panniculitis, urticaria, bullae, erythema multiforme and lichen planus-like lesions. It has long been recognized that dystrophic soft tissue calcification may occur in association with certain connective tissue disorders such as scleroderma or dermatomyositis. Soft tissue calcification in a patient with SLE has been rarely reported. We have experienced a patient with SLE who presented with diffuse subcutaneous tissue calcification on face, chest, abdomen and all extremities.

OBJECTIVE: To investigate the bone mineral density(BMD) in Korean postmenopausal women. METHODS: We performed the retrospective study for 1,508 postmenopausal women who had menopause after 40 years of age and didn't take any hormonal agent before measuring bone mineral density. Spinal and femur neck BMD were measured using dual energy X-ray absorptiometry(DXA, Lunar Co.). RESULTS: The mean age of the study subjects was 53.7+/-5.7 years and the average BMD of the lumbar spine(L2-L4; L24) and femur neck(FN) were 0.996+/-0.173 g/cm(2) and 0.821+/-0.133 g/cm(2), respectively. Of all subjects, 44.1%(665/1,508) had osteopenia and 14.7%(222/1,508) were already osteoporotic. The prevalence of osteoporosis increased with age; 5.2% in 41-50 years of age, 15.6% in fifties, 32.5% in sixties, and 45.5% in over 70 years of age. There was no significant difference in the age-adjusted BMD between naturally menopausal women(n=828) and surgically menopausal women(n=78). The mean age at menopause of surgically menopausal women was significantly younger than that of naturally menopausal women(47.6+/-3.6 vs 49.2+/-3.5). Duration of menopause, body weight, and height were revealed to be the significant risk factors for osteoporosis. The annual bone loss rates in lumbar spine and femur neck were 1.2% and 1.1% respectively in naturally menopausal women, and 1.5% and 1.2% in surgically menopausal women. CONCLUSIONS: This study established the BMD curve and regression equation in Korean postmenopausal women according to the causes of menopause. There was no significant difference in the mean BMD and the prevalence of osteoporosis between naturally and surgically menopausal women. Duration of menopause, body weight, and height were found to be the risk factors which influence the development of the osteoporosis. So the postmenopausal women who are at increased risks of developing osteoporosis need more active interventions for preventing the osteoporotic fracture.

PURPOSE: The aim of this study was to evaluate the periodontal and prosthodontic complications of multiple freestanding implants in the posterior jaws for up to 1 year of function. MATERIAL AND METHODS: Eight patients received 20 implants posterior to canines. Two or more implants were consecutively inserted to each patient. Single crowns were delivered onto the implants. Marginal bone loss, implant mobility, probing depth, and screw loosening were examined to evaluate the clinical success of such restorations for maximum 1 year of functional loading. RESULTS: All the implants performed well during the observation period. Neither periodontal nor prosthodontic complications were found except a slight porcelain chipping. While the marginal bone level was on average 0.09 mm lower around the implant after 6 months of loading, it was 0.15 mm higher after 1 year. CONCLUSION: Within the limits of this investigation, separate single-tooth implant restorations to replace consecutive missing teeth may clinically function well in the posterior jaw.
