Purpose: This study aims to get the fundamental data which is necessary to the development direction of implant surface treatment hereafter, based on the understanding the surface structure and properties of titanium which is suitable for the absorption of initial tissue fluid by researching effects of additional surface treatments for sandblasted with large grit and acid-etched(SLA) titanium on surface micro-roughness, static wettability, fibronectin adsorption. Materials and Method: In the Control groups, the commercial pure titanium disks which is 10mm in diameter and 2mm in thickness were treated with HCI after sandblasting with 50micrometer Al2O3. The experiment groups were made an experiment each by being treated with 1) 22.5% nitric acid according to SLA+ASTM F86 protocol, 2) SLA+30% peroxide, 3) SLA+NaOH, 4) SLA+Oxalic acid, and 5) SLA+600degree C heating. In each group, the value of Ra and RMS which are the gauges of surface roughness was measured, surface wettability was measured by analyzing with Sessile drop method, and fibronectin adsorption was measured with immunological assay. The significance of each group was verified by (SPSS, ver.10.0 SPSS Inc.) Kruskal-Wallis Test.(alpha=0.05) And the correlation significance between Surface micro-roughness and surface wettability, surface roughness and fibronectin adsorption, and surface wettability and fibronectin adsorption was tested by Spearman's correlation analysis. Result: All measure groups showed the significant differences in surface micro-roughness, surface wettability, and fibronectin adsorption.(p<0.05) There was no significance in correlation among the surface micro-roughness, surface wettability, and fibronectin adsorption.(p>0.05) Conclusion: Surface micro-roughness and surface wettability rarely affected the absorption of initial tissue fluid on the surface of titanium.

PURPOSE: The aim of this study was to examine the relationship between tooth loss and sub-clinical atherosclerosis in Korean adults. MATERIALS AND METHODS: The subjects were part of a cohort study conducted in Ansan city by the Korea University medical school as part of the Korean Genome project. 749 subjects over than 40 years old were evaluated. After taking panoramic radiography, the amount of tooth loss was calculated. The intima-media thickness (IMT) was assessed by using ultrasonography at the common carotid artery. Traditional cardiovascular risk factors for atherosclerosis were also evaluated. The relationship between tooth loss and the IMT was evaluated using ANOVA with Scheffe's multiple comparison method in univariate analysis. Multiple regression analysis was also performed to determine the significance between the IMT and tooth loss. RESULTS: With age, tooth loss increased, but there was no significant increase in other traditional cardiovascular risk factors. Univariate analysis revealed the IMT to be positively related with the amount of tooth loss. Regression analysis of the IMT in the anterior and posterior tooth loss revealed that only the posterior tooth loss was significantly related with the IMT at all sites of the common carotid artery (right far wall, P = .015; left far wall, P = .008; right near wall, P < .001; left near wall, P = .001). CONCLUSION: This study verified the positive relationship between the increased tooth loss at the posterior area and the accumulation of atheroma in arteries.

BACKGROUND: The purpose of this study was to compare the clinical outcome in patients aged less than 55 years who underwent arthroscopic tenodesis and arthroscopic repair for type 2 superior labrum anterior and posterior (SLAP) lesions. METHODS: Between April 2008 and December 2014, surgery was performed on a total of 45 patients with isolated type 2 SLAP lesions. Arthroscopic repair was performed in 22 patients and arthroscopic tenodesis was performed in 23 patients. In both groups, the clinical outcomes at follow-ups were evaluated using the University of California at Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and visual analogue scale (VAS) score. RESULTS: In both groups, the VAS scores for pain had improved significantly throughout the postoperative follow-up period. The VAS score showed a statistically significant difference at postoperative 3 and 6 months (p<0.05); however, there was no statistically significant difference between preoperative and postoperative results at 12 months (p>0.05). In both groups, the functional outcome was statistically improved postoperatively. In a comparison of the UCLA and ASES scores between the two groups, there was a statistically significant difference at postoperative 3 and 6 months (p<0.05), but there was no statistically significant difference between preoperative and postoperative results at 12 months (p>0.05). CONCLUSIONS: Based on the results of this and other studies, patients with isolated type 2 SLAP lesions showed better short-term clinical outcome with tenodesis than with repair. However, there was no difference between the two groups at the final follow-up.

Though the incidence of paragonimiasis has been remarkably decreased since 1970, it is still not a rare disease in Korea. Major problems in the diagnosis of pulmonary paragonimiasis on chest radiography are its differentiation from pulmonary tuberculosis and lung cancer. Chest radiographic findings have been described in detail, but little have been reported on CT findings. We reviewed CT findings of 10 patients with pulmonary paragonimiasis. The characteristic CT findings were similar to those on chest radiography, such as air-space consolidation (70%), nodular mass (50%), pleural effusion (40%), cystic lesion (30%), small low density within the mass (30%), linear density (20%), pneumothorax(20%), and burrow track (20%). CT depicted the cystic lesions and the burrow tracks more clearly and showed the small worm-retaining cysts within the mass that were not detectable on chest radiography. In conclusion, all of these CT findings are useful in the diagnosis of pulmonary paragonimiasis especially when differentiation from tuberculosis or lung canceris difficult on chest radiography.

Frozen shoulder is a disease characterized by shoulder pain and limited range of motion. Conservative treatment is preceded by surgical treatment to reduce pain and recover range of motion. Hydraulic distention is a procedure in which a sufficient amount of solution is injected into the shoulder joint to rupture the rigid joint capsule. Recently, the method of continuously maintaining the expanded capsular state after injection without the process of rupturing the rigid joint has also been used. However, in order to obtain the maximal stretching effect, we proposed a ‘pumping technique’ that inflates and shrinks the rigid joint capsule by repeating the process of infusion and regurgitation of the injection fluid into the capsule. Our proposed ‘pumping technique’ was shown to be more effective in increasing range of motion than the conventional hydraulic distension. This ‘pumping technique’ can be suggested as an effective therapeutic option for frozen shoulder.

To obtain adequate information of illumination and lens types for visual acuity test of low vision patient, the relation between various illumination and vision was evaluated. Visual acuity for near and effective lens types were examined. Among the 28 patients (of 36 eyes), intensities of illumination were set at 200, 500, 1000 and 2000lux and the lenses of biconvex, aspheric and aplanatic were tested. The best visible range of illumination for the low vision patients was 500-1000lux, with lower power diopter for the same visual acuity and with aspherin and aplantic lenses. Results attained by our study may be applied for appropriate condition of illumiation and type of lens in the low vision care.

"Background: In using the Double-lumen tube (DLT), knowing the minimum bronchial cuff volume (MCV) for an effective air-tight seal will be useful; to provide a collapse of the lung; and to avoid pressure damage. The aims of the present study are thus three-fold: to measure the MCV; to measure the diameter of left main bronchus (LMBD); and to prove any relationships between two parameters. METHODS: One hundred men and forty women who needed intubation of left-sided DLT were enrolled in this study. 37 Fr DLTs were used in male patients, and 35 Fr DLTs were used in female patients. We evaluated the MCV by air bubble method and measured the LMBD in chest PA. We also evaluated the pressure/volume characteristics of the bronchial cuffs by control inflator. RESULTS: 29 patients of 100 patients (29%) exhibited persistent air leakage in 2.5 ml cuff volume in male patients (group of MCV >2.5). On the contrary, 18 patients of 40 patients (45%) did not require any cuff volume in female patients (group of MCV 0). The mean LMBD were 13.23 1.45 mm in male and 11.09 0.96 mm in female. There were significant positive correlations between MCV and LMBD in both sex and their respective correlation coefficients were 0.264 (P=0.008) in male and 0.484 (P=0.002) in female. The equations of linear regression were: LMBD = 12.394 0.429xMCV in male, LMBD = 10.725 0.438xMCV in female. CONCLUSIONS: The MCV of the brochial cuffs in left-sided DLTs has significant relationships with the LMBD measured in chest PA.
