A retrospective review was performed of 297 patients admitted to Chung Ang Gil Hospital between June 1995 and December 1996 with a diagnosis of blunt chest trauma. Of these patients, 34% suffered either immediate or delayed complications. Immediate complications included hemothorax in 58.8%, pneumothorax in 26.5%, and pulmonary contusion in 20.5%. Delayed complications occurred in 9.1% of patients overall; these included pulmonary contusion in 12.7%, pneumonia in 9.8%, pulmonary embolism in 2%, poeumothorax in 2%, and hemothorax in 2%. The mean age of the patients were 43 years. 210 patients(70.7%) were under age 50 and 87(29.3%) were 50 years of age or older. Male to female ratio was 1.9:1. Mean Initial Revised Trauma Score (RTS) and the Injury Severity Score (ISS) were 7.10+/-0.94 and 14+/-8.69, respectively. There were associated injuries in 225(75.8%) patients. Overall mortality rate was 7.1% and the mortality rate was significantly greater in patients with a RTS<6, ISS>or=16, associated injuries, advanced age(50 years of age or older), and pulmonary complications. Pulmonary complications were significantly greater in patients with a RTS<6, ISS>or=16, and an associated injuries.

Forty eight female Sprague-Dawley rats received a subcutaneous implant containing 12.5 mg estradiol ant the age of 3 weeks. Three rats were killed in 1, 2, 3, 4, 6 weeks and in every month during 2~12 months after implantation, and the breasts were examined by light microscope. In all rats, enlargement of terminal end buds was obseved in 1~2 weeks, maximum development of hyperplastic alveolar nodules in 3 weeks, and marked dilatation and secretion of alveoli or ducts in 1~12 months after implantation. Ductal epithelial hyperplasia was observed in 27 rats and carcinomas developed in 23 rats in 2~12 months after implantation. It was thought that the changes induced by estradiol are more similar to the human breast lesions, compared with changes induced by chemical carcinogens such as dimethylbenzanthracene(DMBA), because breast carcinomas developed in close relationship with ductal epithelial hyperplasia in both estradiol-treated rats and humans, but not in DMBA-treated rats.

PURPOSE: To determine whether neoadjuvant androgen deprivation therapy (NADT) improves clinical outcomes in patients with prostate cancer treated with definitive radiotherapy. MATERIALS AND METHODS: We retrospectively reviewed medical records of 201 patients with prostate cancer treated with radiotherapy between January 1991 and December 2008. Of these, 156 patients with more than 3 years of follow-up were the subjects of this study. The median duration of follow-up was 91.2 months. NADT was given in 103 patients (66%) with median duration of 3.3 months (range, 1.0 to 7.7 months). Radiation dose was escalated gradually from 64 Gy to 81 Gy using intensity-modulated radiotherapy technique. RESULTS: Biochemical relapse-free survival (BCRFS) and overall survival (OS) of all patients were 72.6% and 90.7% at 5 years, respectively. BCRFS and OS of NADT group were 79.5% and 89.8% at 5 years and those of radiotherapy alone group were 58.8% and 92.3% at 5 years, respectively. Risk group (p = 0.010) and radiation dose > or =70 Gy (p = 0.017) affected BCRFS independently. NADT was a significant prognostic factor in univariate analysis, but not in multivariate analysis (p = 0.073). Radiation dose > or =70 Gy was only an independent factor for OS (p = 0.007; hazard ratio, 0.261; 95% confidence interval, 0.071-0.963). CONCLUSION: NADT prior to definitive radiotherapy did not result in significant benefit in terms of BCRFS and OS. NADT should not be performed routinely in the era of dose-escalated radiotherapy.

While lipomas are common in the rest of the body, intracranial lipomas are rare condition which are usually found in the midline of the brain. The majority of these lesions show few or even no symptoms and hardly ever produce alarming neurological defects. We experienced a case of corpus callosum lipoma in a 7 year old boy, who has had headache and loss of consciousness twice. He was diagnosed by skull x-rays and brain CT. We made a brief review of literatures. @PG 428.
