The purpose of this study is to obtain information of simple and effective methods for the pos-tlaminectomy pain control, and to reduce the consumption of supplemental analgesic drugs and side effects. In a double blind study, 75 patients scheduled for lumbar laminectomy were randomly divided into five groups according to the epidurally instilled drugs, such as, morphine 2mg,Group M2; morphine 3mg,Group M3; methylprednisolone 80 mg, Group D; morphine 2mg plus methylprednisolone 80mg, Group M2D; normal saline as a control Group C. All of the drugs were prepared in 2ml normal saline solution. The following items were recorded in the postoperative period: Pain score using visual analogue scale(VAS) at 6, 12, 24, 48 hours after the operation; the episode of supplemental systemic analgesic; the need for postoperative urethral catheterization; any evidence of respiratory depression; pruritus; nausea and vomiting. The results were as follows. I) VAS score were not significantly different between control group and group M2(p>0.05), but usually less in the group M2 and supplemental analgesic consumption was significantly less in the group M2 than in the control group. 2) VAS score were less in the group M3 than in the group M2 and significantly less than in the control group at 6 hour after operation and also supplemental analgesic consumption was significantly less in the group M3. 3) Group D revealed similar VAS score with group M2 at 6 and 12 hour but significantly lower VAS score at 24 and 48 hour after operation than group M2. 4) VAS score were the most significantly less in the group M2D at 6,12,24,48 hour after operation than in the control group and supplemental analgesic consumption was significantly less in the group M2D. 5) Side effects were not significantly different among all groups. These findings suggest that epidurally instilled morphine 3mg, or methylprednisolone 80mg or both before the closure of the laminectomy wound is effective, simple and safe method for the post-laminectomy pain control and reducing supplemental intramuscular analgesics without specific complication.

PURPOSE: To identify factors associated with care of diabetic retinopathy. METHODS: The fourth Korea National Health and Nutrition Examination Survey (KNHANES IV) is a nationwide survey. This survey included 1, 257 people aged 40 years and older with a history of diabetic mellitus who answered questions, "Within one year, have you ever received eye examination (fundus photography) for screening diabetic retinopathy?" Factors that affect care of diabetic retinopathy were identified using multiple logistic regression analysis. RESULTS: Among the 1,257 people aged 40 years and older, 464 (36.9%) received screening for diabetic retinopathy. People aged 65 years and older (aOR = 0.7, 95% CI: 0.51-0.85) with university education (aOR = 0.5, 95% CI: 0.32-0.74) were more likely to undergo screening for diabetic retinopathy compared to those in the reference category (40-64 years old and those who had elementary school or lower education). People living in rural areas were less likely to undergo screening for diabetic retinopathy compared to those living in urban areas (aOR = 1.7, 95% CI: 1.32-2.24). Diabetic retinopathy screening was also associated with self-reported health status (ref: unhealthy [aOR = 1], fair [aOR = 1.7, 95% CI: 1.25-2.23], and healthy [aOR = 1.8, 95% CI: 1.30-2.44]). CONCLUSIONS: To increase nationwide screening rates for diabetic retinopathy, more attention should be given to underserved groups, particularly people aged between 40 and 64 years, those with a low education level, those living in rural areas, and those with a positive attitude toward self-reported health status. These issues highlight the need for a new emphasis in health education and public health policies aimed towards these underserved groups.

BACKGROUND AND OBJECTIVES: A computerized database system could provide benefit to reducing the variability of reporting results of chronic ear surgery, where a variety of factors may influence the outcomes. In the present study, the factors contributing to hearing gains after chronic ear surgery were investigated using a computerized database. MATERIALS AND METHODS: Audiometric data were easily drawn from the database log of 622 surgical cases of chronic otitis media done by one surgeon from 1989 to 1996. Of these, 309 were collected with the inclusion criteria being the period of no shorter than 3 months following tympanoplasty procedures. Post-operative hearing gains were compared according to the patient factor (sex, age), disease factors (unilateral vs bilateral disease, existence of cholesteatoma, preoperative otorrhea), surgery factor (primary versus revision operation, types of mastoidectomy, ossiculoplasty, hearing status of the operated ear), and the surgeon's experience. RESULTS: Pre- and post-operative air-bone gaps of the pure tone averages for the 309 cases studied were 34.6+/-13.4 dBHL and 24.9+/-13.8 dBHL, respectively. The post-operative hearing gains were 9.6+/-13.6 dBHL. The hearing gains did not differ significantly beween the groups when it is compared with regards to the factors, such as sex and age of patients, revision operation, hearing status, surgeon's experience. But the hearing gains differed with regards to the other factors, such as cholesteatoma, otorrhea, mastoidectomy and ossiculoplasty (p<0.05). CONCLUSION: This kind of computerized database is very useful to assess the effect of factors on the hearing gains following chronic ear surgery.

PURPOSE: The reliability and validity of a Korean version of the Obsessive-Compulsive-Inventory-Revised (OCI-R) was examined in non-clinical student samples. MATERIALS AND METHODS: The Korean version of OCI-R was administered to a total of 228 Korean college students. The Maudsley Obsessive Compulsive Inventory (MOCI), Beck's Depression Inventory (BDI), and Beck's Anxiety Inventory (BAI) were administered to 228 students. RESULTS: The total and each of subscale of the Korean OCI-R demonstrated excellent internal consistency, good test-retest reliability, moderate convergent validity and good divergent validity. CONCLUSION: It was concluded that the Korean version of the OCI-R has strong psychometric properties as the original version.

PURPOSE: This study was performed to find a method to utilize demineralized bone matrix as a vehicle for local delivery of the antibiotics for the treatment of chronic osteomyelitis. MATERIALS AND METHODS: Bovine bone blocks with the same size were randomly divided into 4 groups. Using Demineralization and hematoma coating, the different characteristics were given to each group, and Vancomycin was adsorbed to these bone blocks. We performed two identical experiments with Phosphate-buffered Saline and Fetal Bovine Serum as a solute. We exchange the solution with 24-hour interval for 6 weeks. The eluted concentrations of Vancomycin at each week were measured. RESULTS: Regardless of the solution used, the eluted concentration of Vancomycin was significantly higher in demineralized and hematoma-coated group than those of other groups. The eluted concentration of Vancomycin were 22.6ng/ml at week 6 in saline condition and 12.4ng/ml at week 5 in serum condition. CONCLUSIONS: We thought that demineralized and hematoma-coated cancellous bone can be used as a good vehicle for local antibiotics delivery.

PURPOSE: The Gleason score is an important predictor of outcome that is used in conjunction with clinical stage and prostate-specific antigen to guide clinical decision making. The prostate biopsy Gleason grade frequently differs from the radical prostatectomy grade. The aim of this study was to determine the risk factors of Gleason upgrading in patients with low-risk prostate cancer after radical prostatectomy. MATERIALS AND METHODS: We retrospectively analyzed the medical records of 146 patients who underwent radical prostatectomy between 1998 and 2008 in two hospitals of Jeonbuk province in Korea. Pathological Gleason score upgrading was defined as an increase in the Gleason score from < or =6 to > or =7 between the biopsy and radical prostatectomy specimen. Pretreatment clinical and pathological parameters were used to identify predictors of pathological upgrading. RESULTS: Of the total 146 patients, 51 (34.9%) were upgraded postoperatively. Small prostate volume (p=0.008), abnormality on the digital rectal examination, and positive surgical margin (p=0.001) were significantly and positively associated with upgrading after radical prostatectomy. A total of 17 of 65 patients with low-risk prostate cancer (26.2%) were upgraded postoperatively. Small prostate volume (<30 ml) was significantly (p=0.026) and positively associated with upgrading after radical prostatectomy in patients with low-risk prostate cancer. CONCLUSIONS: Overall, 26% of patients with low-risk disease were upgraded postoperatively. Small prostate volume was associated with an increased risk for pathological upgrading after radical prostatectomy. These conclusions should be kept in mind when making treatment decisions for men with low-risk prostate cancer.

PURPOSE: To investigate associations between serum thyroid stimulating hormone (TSH) receptor antibody (TRAb) levels and Graves' orbitopathy (GO) activity/severity in chronic-stage GO and compare the performance of two newly-developed TRAb assays (third-generation TSH-binding inhibition immunoglobulin [TBII] assay versus Mc4 thyroid-stimulating immunoglobulin [TSI] bioassay). METHODS: This study is a retrospective review of medical charts and blood tests from Korean GO patients who first visited the departments of ophthalmology and endocrinology, Yonsei University College of Medicine from January 2008 to December 2011, were diagnosed with GO and Graves' hyperthyroidism, and were followed up for > or =18 months. Third-generation M22-TBII and Mc4-TSI assays were performed in the chronic-inactive GO patients in whom euthyroidism status was restored. Patients' GO activity/severity clinical activity scores (CAS), and modified NOSPECS scores were examined for a correlation with TRAb assays. RESULTS: Fifty patients (mean age, 41.3 years; 41 females) were analyzed. The mean duration of Graves' hyperthyroidism symptom was 63 months (range, 18 to 401 months) and that of GO was 46 months (range, 18 to 240 months). All patients had been treated previously with anti-thyroid drugs for a median period of 52.3 months, and two patients underwent either radioiodine therapy or total thyroidectomy. Mean CAS and NOSPECS scores were 0.5 +/- 0.9 (standard deviation) and 4.8 +/- 3.1, respectively. Mean M22-TBII and Mc4-TSI values were 7.5 +/- 10.2 IL/L and 325.9 +/- 210.1 specimen-to-reference control ratio. TSI was significantly correlated with NOSPECS score (R = 0.479, p < 0.001); however, TBII was not associated with NOSPECS score (p = 0.097). Neither TSI nor TBII correlated with CAS (p > 0.05), because GO inflammatory activity subsided in the chronic stages of GO. CONCLUSIONS: In chronic-inactive GO after euthyroid restoration, GO activity score did not associate with serum levels of TRAb or TBII. However, levels of the functional antibody Mc4-TSI did correlate with GO severity. Therefore, the TSI bioassay is a clinically relevant measure of disease severity even in chronic inactive GO.

Papillary eccrine adenoma is a rare cutaneous tumor which occurs most commonly on the distal portion of extremities as a small solitary nodule. Histopathologically, the tumor consists of multiple dilated or branching tubular structures that are lined by two or more layers of epithelial cells and shows papillary projection into the lumina. Positive staining with S-100 protein, CEA, EMA and keratin in papillary eccrine adenoma is consistent with differentiation toward the secretory epithelium of eccrine sweat gland. Herein we report four cases of papillary eccirine adenoma and review the literature.
