PURPOSE: Distribution and survival of sarcoma in Korea are not well described, after the changing of sarcoma classification on 2013. The researchers investigated the distribution and survival in single center 2017 cases of sarcoma.METHODS: Patients with primary sarcoma, who underwent surgery, were investigated. All cases were collected during a 20 year period (1995–2015) from Samsung Medical Center in Korea. Histopathologic types were classified by World Health Organization (WHO) classification (2013). And overall survival rates were analyzed.RESULTS: Between 1995 and 2015, 2017 patients were collected. The most frequent type of sarcoma was gastrointestinal tumor (15%), followed by liposarcoma (12%), leiomyosarcoma (9%), dermatofibrosarcoma (6%), giant cell sarcoma (6%). The most common primary site of sarcoma was the intra-abdominal area (45%, including visceral area). Extremities accounted for 26% of all cases. Sixteen percent of sarcoma were located in retroperitoneal area. The overall survival rate was 70.4% (median follow-up time, 36.8 months; range, 0.1–261.3 months). The best prognosis was dermatofibrosarcoma (100%, 5-year survival rate). The worst prognosis was angiosarcoma (39.3%). Survival analysis by the primary site demonstrated favor prognosis in extremities than head & neck, chest lesion.CONCLUSION: The researchers reported Korean sarcoma characteristics with using the new WHO classification.

Adipogenesis in murine preadipocyte 3T3L-1 has been used as a model system to study anti-obese bioactive molecules. During adipogenesis in 3T3-L1 preadipocytes, we found that capsanthin inhibited adipogenesis (IC₅₀; 2.5 μM) and also showed lipolytic activity in differentiated adipocytes from the preadipocytes (ED₅₀ ; 872 nM). We identified that the pharmacological activity of capsanthin on adipogenesis in 3T3-L1 was mainly due to its adrenoceptor-β2-agonistic activity. In high-fat diet animal model study, capsanthin significantly enhanced spontaneous locomotive activities together with progressive weight-loss. The capsanthin-induced activation of kinetic behavior in mice was associated with the excessive production of ATP initiated by both the enhanced lipolytic activity together with accelerated oxidation of fatty acids due to the adrenoceptor β2-agonistic activity of capsanthin. Capsanthin also dose-dependently increased adiponectin and p-AMPK activity in high fat diet animals, suggesting that capsanthin has both anti-obesity and insulin sensitizing activities.

Traumatic peroneal tendon dislocation in association with fracture of the lateral process of the talus is a rare injury, which is difficult to diagnose. As a result, early detection is often delayed, which in turn leads to ankle pain and dysfunction. We treated a patient by open reduction and screw fixation in fracture of the lateral process of talus and primary repair of the superior peroneal retinaculum. We report this case with a brief review of the literature.

Subarachnoid-pleural fistula after routine thoracotomy is a rare complication but a very serious problem. Twenty one cases have been reported in the literature. We report a care of subarchnoid-pleural fistula that dveloped after the esecation of posterior mediastinal neurogenic tumor. The patient presented with large amount of clear pleural fluid with mild headache and dizziness. Surgical intervention following a trial of conservative therapy was undertaken because we strongly suspected subarachnoid-pleural fistula. A dural tear was found at the level of resected intercostal nerve root. The dura was closed by way of direct suture and fibrin glue. In this case, the recognition of subarachnoid-pleural fistula formation is difficult because the patient had not presented any neurologic deficit.
