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.

BACKGROUND: It is one of anesthesiologist's important tasks to know the accurate recovery state of a patient after general anesthesia. Postanesthetic recovery score (PARS) has been widely used as a measure of evaluating recovery state because it is simple, easy to apply and applicapable to all situations. In this study, we investigated whether there were correlations between PARS and PAR-stay time, and examined factors influencing PAR-stay time. METHODS: Two hundreds and five patients were selected randomly. PARS was measured in each patient immediately after he or she arrived at PAR. Correlations between PARS and PAR-stay time were studied. And other variables such as age, sex, physical status, operation site and anesthetic time were studied as influencing factors on PAR-stay time. RESULTS: There were no significant correlations between PARS and PAR-stay time. PARS was influenced by the operation site only. And PAR-stay time was influenced by the patient's age only. CONCLUSIONS: In evaluating the postanesthetic recovery state, it seems to be important to consider not only PARS but also other factors such as patient's age.

The sheaths of tendons are an uncommon site of tuberculous invclvement as compared to other parts of the body. But tuberculou, tenosynovitis occurs often enough to varrant particular attention and study. We report a case of tuberculous tenosynovitis occuring in a 49-year-old woman who had multiple yellowish palpable nodules and swellings distributed along the tencon of flexor digitorum superficialis on the left palm for 3 month. Histopathologic findings showed multip e tuberculoid granulomas in the mid-and deep-dermis. Eosinophilic homogenous trabeculated structure(remnants of tendon sheath resistant to necrosis) was present within the area of caseation. Acid-fast stain showed a crowd of acid-fast bacilli in the deep dermis. The cultures from the skin biopsy spec mens on Ogawa media(3% KH PO4) at 24C, 32C and 37C were all negative. She was treated with surgical excision of granulation tissue and involved tendon sheath followed by systemic administration of INH, RIF and ethambutol for 1 year. The lesions were markedly improved and showed no relaps, during last 5 months of follow up period.

PURPOSE: This study purposed to measure the standard volume of the cerebellum of normal Koreans who were in their 20s and 40s, and we also wished to find out the difference in the volume of the cerebellum according to gender and age. MATERIALS AND METHODS: This study collected MR brain images from 118 people in their 20s (males: 58, females: 60) and 100 people in their 40s (males: 41, females: 59), for a total of 218 people. For each of sagittal, coronal and axial sections, the cerebellar part of the images was segmented using automatic and manual methods, and the volume was then measured. In order to observe differences according to gender and age and also to observe the interactive effect between gender and age, a two-way ANOVA test was performed using gender (2 levels) and age (2 levels) as independent variables. RESULTS:The average volume of the cerebellum of Koreans in their 20s was 133.74 (cm3) and that of Koreans in their 40s was 121.83 (cm3). The average volume of the cerebellum of male Koreans in their 20s and 40s was 134.55 (cm3) and that of female Koreans was 123.06 (cm3). The volume of the cerebellum was significantly larger in Koreans in their 20s than those volumes of the cerebellum of Koreans in their 40s, and the cerebellum volumes in male Koreans were larger than those of the Korean females. Moreover, the reduction of the volume of the cerebellum with age was significantly larger in male Koreans than in the Korean females. CONCLUSION: According to the results of measuring the volume of the cerebellum for normal Koreans in their 20s and 40s, the volume was significantly different according to gender and age, and the reduction of the volume of the cerebellum with age was significantly larger in men than in women.

PURPOSE: The purpose of this study was to evaluate the role of immediate postoperative radiotherapy (RT) in adult patients with a low-grade oligodendroglioma (LODG). MATERIALS AND METHODS: A total of 74 patients, older than 15 years, were treated in our institution between April 1990 and March 2006 for newly diagnosed LODGs. After surgery, 43 patients were treated with immediate RT with a total dose of 54~55.8 Gy with 1.8 Gy fractions (RT group) and 31 patients were followed with no adjuvant RT (OP group). All patients were closely observed until tumor progression or death with frequent work-ups including neurological examinations and MRI. Primary endpoints were overall survival and progression-free survival. The median follow-up duration of survivors was 6.2 years in the RT group and 5.8 years in the OP group. RESULTS: Median progression-free survival was 13.2 years in the RT group and 4.6 years in the OP group; multivariate analysis confirmed improved outcome with the use of immediate RT (hazard ratio, 0.22; 95% confidence interval-CI, 0.09~0.55; p<0.001). Median overall survival was 14.9 years in the RT group and 9.8 years in the OP group; the use of adjuvant RT was also associated with a trend toward better overall survival after immediate RT based on multivariate analysis (hazard ratio, 0.3; 95% CI, 0.08~1.17; p=0.082). No severe RT related complications were observed. CONCLUSION: Immediate RT following surgery appears to be an effective treatment modality for supratentorial LODGs. However, the potential benefit of adjuvant RT for overall survival needs to be tested prospectively in the future.

Kernicterus is a neurologic syndrome, resulting from the preferential deposition of unconjugated bilirubin in the globus pallidus, subthalamus, hippocampus, and brain stem. The characteristic finding of kernicterus revealed by T2-weighted MR imaging is irreversible, bilaterally symmetrical high signal intensities in the globus pallidus. We report an atypical case of kernicterus, in which follow-up MR imaging of the globus pallidus demonstrated reversible signal intensity.

OBJECTIVE: Unruptured intracranial aneurysms are now being detected with increasing frequency in clinical practice. Results of the largest studies, including those of the International Study of Unruptured Intracranial Aneurysms, indicate that surgical and endovascular treatments are rarely justified in small aneurysms. However, we have encountered several cases of rupture of small and very small aneurysms in our clinical practice. This retrospective study analyzed the incidence and clinical characteristics of very small ruptured aneurysms. MATERIALS AND METHODS: A total of 200 patients with aneurysmal subarachnoid hemorrhage between January 2012 and December 2014 were reviewed. Various factors were analyzed, including the aneurysm location and size as well as the associated risk factors. RESULTS: The mean age of patients was 56.31 +/- 13.78 (range, 25-89) years, and the male to female ratio was 1:2.1. There were 94 (47%) small-sized (< 5 mm), 91 (45.5%) medium-sized (5-9.9 mm), and 15 large-sized (> 10 mm) aneurysms. Of these, 30 (15%) aneurysms were very small-sized (< 3 mm). The most frequent site of aneurysms was the anterior communicating artery (ACoA). However, the proportion of aneurysms at the ACoA was significantly high in very small aneurysms (53.3%, p = 0.013). Hypertension was a significant risk factor for rupture of very small aneurysms (p < 0.001). CONCLUSION: About half of our cases of ruptured aneurysms involved the rupture of small and very small aneurysms. The most common site of rupture of very small aneurysm was the ACoA. Rupture of small and very small aneurysms is unpredictable, and treatment may be considered in selected high-risk patients according to factors such as young age, ACoA location, and hypertension.
