Clinical outcome of low-grade central osteosarcoma and role of CDK4 and MDM2 immunohistochemistry as a diagnostic adjunct
Low-grade osteosarcoma encompasses parosteal osteosarcoma (POS) and low-grade central osteosarcoma (LCOS), with LCOS more rare than POS. LCOS is also more likely to be misdiagnosed and inappropriately treated ...

Spontaneous necrosis and additional tumor necrosis induced by preoperative chemotherapy for osteosarcoma: a case–control study
Extent of spontaneous necrosis in untreated osteosarcoma may imply tumor aggressiveness. Reports regarding this issue are scarce and there are several points to be clarified; (1) the correlation between tumor ...

A Microsurgical Suture Technique Without the Need for Vascular Clamps
Vascular clamps are often used during microvascular repair and anastomosis. However, pressure exerted by the clamps may damage the vessels, which compromises patency of vessels. This article reports on a micro...

A split-face, evaluator-blind randomized study on the early effects of Q-switched Nd:YAG laser plus Er:YAG micropeel (combined therapy) versus Q-switched Nd:YAG alone in light solar lentigines in Asians
Solar lentigines are a common sign of aging in Asians, who often asked for treatment. Various lasers, including Q-switched Nd:YAG and Er:YAG, have been adopted, but the results are not always satisfactory, esp...
