BACKGROUND: The purpose of this study was to investigate the clinical and radiological outcomes of locking plate fixation with fibular strut allograft to manage unstable osteoporotic proximal humerus fractures. METHODS: We retrospectively reviewed 15 patients who underwent open reduction and locking plate fixation with fibular strut allograft for osteoporotic proximal humerus fracture between July 2011 and June 2015. For functional evaluation, we evaluated visual analogue scale (VAS) pain score, American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles (UCLA) shoulder score, and active range of motion. For radiological evaluation, shoulder true anteroposterior (AP) and AP in 20° external rotation, as well as the axillary view were taken at two weeks, six weeks, three months, six months, and one year. And the neck-shaft angle was measured on the AP view in 20° external rotation view. RESULTS: At the one-year follow-up, mean VAS pain score and all shoulder scores, including ASES score and UCLA shoulder score, exhibited satisfactory clinical outcomes. All patients obtained bone union between three and six months post-procedure. Moreover, the mean immediate postoperative neck-shaft angle was 138°± 4°, and at one-year follow-up, the neck shaft angle was 137°± 5°. There was no significant difference between the preoperative and postoperative values (p=0.105). CONCLUSIONS: For the unstable two-part and three-part osteoporotic proximal humerus fractures with medial calcar comminution, the use of fibular strut allograft with locking plate fixation was effective in maintaining the initial status of reduction and exhibiting the satisfactory functional and radiological outcomes.

We have investigated an immunohistochemical expression of the Human-Ha-ras oncogene product p21 in tumor cells of the primary mass and metastatic lymph nodes with different histological features of gastric cancer by using avidinbiotin complex immunoperoxidase method in formalin-fixed tissue sections from 73 cases of primary tumor mass and 23 cases of metastatic lymph node. Histologic type of the gastric cancer was classification. The results obtained were as follows: 1) Expression of Ha-ras p21 was consistantly increased in the well differentiated tubular adenocarcinoma as compared with poorly differentiated tubular adenocarcinoma (p<0.01), and was substantially decreased in mucinous carcinoma and signet ring cell carcinoma. 2) Signet ring cell carcinoma showed that positive immunoperoxidase reaction for Ha-ras p21 exhibited in the majority of immature signet ring cell with scant cytoplasm rather than in the mature signet ring cells which have abundant cytoplasm filled with mucin. This findings indicate that mucin production from the tumor cell was not correlated with activation of ras gene in the tumor tissue of gastric carcinoma. 3) In general Ha-ras p21 expression was enhanced in the metastatic tumor cells of the regional lymph node compared with primary tumor, especially it was consistantly increase in the well differentiated tubular adenocarcinoma.

A rare case of mesothelial/monocytic incidental cardiac excrescences (cardiac MICE) is described in the aspect of pathological interest. This cardiac lesion is pathologically characterized by exuberant proliferation of mixed mesothelia and monocytes and might be misdiagnosed as metastatic carcinoma, rhabdomyosarcoma, and histiocytoid hemangioma, if the disease is not in the minds of pathologists. The reactive nodular hyperplasia due to irritation to mesothelia by various causes is a most prevailing pathogenetic mechanism. About 20 cases have been reported in the worldwide literature. A 67-year-old female patient presented with cough and dyspnea for 2 months, without any history of previous cardiac operation. 2D echocardiography of the heart revealed moderate amount of pericardial effusion with posterior wall thickening. Under the impression of metastatic malignancy, pericardiostomy was performed. Grossly, the tissue was dark hemorrhagic and friable and the histologic sections revealed the solid tumor-like proliferation of round to polygonal histiocytic cells admixed with small cuboidal mesothelial cells which formed strips and tubular arrays. They were found within the fibrinous network and there were scattered empty vacuolar spaces. Immunohistochemical staining confirmed their biphasic nature with the CD68 positivity of the histiocytes and the cytokeratin positivity of the cuboidal cells. Factor VIII positivity was not detected in any cell components. The lesion was considered the monocytic and mesothelial proliferation of reactive nature, so-called cardiac MICE in the pericardial cavity. We report a typical case of so-called MICE first in the Korean literature.

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.

Although embryonal rhabdomyosarcoma has been frequently reported in genitourinary tract, head and neck, embryonal rhabdomyosarcoma of the biliary tree is an extremely rarte. It must be considered in differential diagnosis of jaundice in childhood. About 35 cases have been reported in world literatures, since first description on 1875, by Moxon and Wilks. We present a case of embryonal rhabdomyosarcoma of the biliary tree in a 25 months old boy with brief review of literatures. Since chief complaints of this case were jaundice and loss of appetite, the first clinical diagnosis was infectious hepatitis. On ultrasound examination, there is a space occupying lesion in right lobe of liver and it was diagnosed as hepatoma. Choledochoduodenostomy with biopsy was done. The operation revealed dilated common bile dut and both hepatic ducts which were filled with light brown jelly like materials and diagnosed as embryonal rhabdomyosarcoma on frozen and permanent senions. In gross and histologic characteristics, this tumor resembles embryonal rhabdomyosarcoma(sarcoma botryoides) in other locations. In spite of chemo-and radiotherapy after operation, the boy was died.
