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.

We have experienced 52 intra-articular fractures(24 malleolar, 17 patellar, 11 olecranon) treated with tension band wiring from 1972 to 1981 and the results are as followings; 1. The operative technique is relatively simple and easy. 2. In avulsion fractures without communition, anatomical reduction and rigid internal fixation can be achieved. 3. In comminuted fractures, the fragments can be securely fixed with a few additional K-wires including tension band wiring. 4. In avulsion fractures, where the fragment is either too small for screw fixation or too osteoporotic a tension band wiring can be applied with no difficulty. 5. Early joint motion reduces the functional disability and promote the fracture healing.

BACKGROUND: Previous randomized controlled trials (RCTs) have reported inconsistent findings regarding the association between vitamin C supplementation and the risk of cancer. METHODS: We performed a meta-analysis of RCTs to investigate the efficacy of vitamin C supplements for prevention of cancer. We searched the PubMed, EMBASE, and Cochrane Library databases in November 2014 using common keywords related to vitamin C supplements and cancer. RESULTS: Among 785 articles, a total of seven trials were identified, which included 62,619 participants; 31,326 and 31,293 were randomized to vitamin C supplementation and control or placebo groups, respectively, which were included in the final analysis. A fixed-effects meta-analysis of all seven RCTs revealed no significant association between vitamin C supplementation and cancer (relative risk, 1.00; 95% confidence intervals, 0.95-1.05). Similarly, subgroup meta-analysis by dose of vitamin C administered singly or in combination with other supplements, follow-up period, methodological quality, cancer mortality, gender, smoking status, country, and type of cancer also showed no efficacy of vitamin C supplementation for cancer prevention. CONCLUSION: This meta-analysis shows that there is no evidence to support the use of vitamin C supplements for prevention of cancer.

A reproducible noninvasive technique for measuring right ventricular ejection fraction (RVEF) was developed using first pass quantitative radionuclide angiocardiography. Tests were carried out in the right anterior oblique position with a computerized multicrystal scintillation camera with high count rate capabilities. RVEF was calculated on beat to beat basis from the high frequency components of the background-corrected right ventricular time-activity curve. The following results were obtained; 1) In 10 normal adults, RVEF averaged 50.9+/-8.2. In 20 patients with chronic obstructive lung diseases (COPD), RVEF was 37.9+/-6.1% and significantly lower than that of normal persons(P<0.005). 2) There was meaningful correlation between RVEF and forced expiratory volume (FEVI) in patients with COPD (r=0.51). And there was significant difference of RVEF between 13 patients with FEVI less than IL/min (6 patients with right ventricular failure, 7 patients with patients without that) and 7 patients with FEVI IL/min or more (35.7+/-6.0%, 42.1+/-3.2% respectively. P<0.005). 3) All 6 patients with clinical manifestation of right heart failure had abnormal RVEF and had FEVI less than IL/min, which was significantly lower than that of 14 patients without clinical manifestation of right heart failure (33.6+/-4.8%, 39.8+/-5.6%, respectively. P<0.005). 4) In 14 patients without clinical manifestation of right heart failure, 11 patients among whom 7 patients had FEVI less than IL/min, had abnormal RVEF.
