Urinary incontinence is a relatively common and potentially disabling disease affecting the life quality of a patient. Many successful series in the treatment of incontinence by medical or surgical therapy using autologous materials have been reported. However, those who have structural abnormalities, injury around the urethra, and derangements in the nervous system could not be benefited by such treatments. In other countries, the artificial urethral sphincter, introduced in 1972, have achieved satisfactory results and then increased in use; but in Korea, it was not widely used because of many limitations and obstacles. Based on our ten-year experience with 10 cases of implantation of artificial urethral sphincter from 1987 to 1996, we tried to elucidate the present status, problems, and the possible ways of improvements of its use within this country. A total of ten male patients underwent implantations of the AMS Model 800 artificial urethral sphincter. Mean age was 34.5 (17-43) years. Mean follow-up was 4.2 (0.5-10) years. Two patients were spinal cord injury patients, 2 meningomyeloceles, and 6 posterior urethral injuries. Two patients had the prosthesis removed due to infection and cuff erosion. In the other 8 patients, 6 were dry (75.0 %) and 1 was improved (12.5 %) and 1 was wet (12.5 %). The revision rate was 20% (2/10) and overall improvement of incontinence was observed in 7 (87%) patients. The reasons for the low incidence of the implantation of artificial urinary sphincter in this country are as follows. According to the other reports, the most common application of artificial urinary sphincter in the west is in the post-prostatectomy incontinence accounting for about 60% of artificial urinary sphincter implantation whereas in this country, the majority of cases are patients who had trauma. Since radical prostatectomy has not been established well in the country (in the recent 4 years, totally only 53 cases were performed) and also the excellent performance of the transurethral surgery making the incidence of incontinence low, could be one of the reasons. In addition, the high price of the prosthesis over 4 million won and operation fee of 3 to 6 million won is a formidable burden to most patients. In the view of mechanical problem, the cuff size of the urethra in the oriental people is observed smaller than the western, and we must let the company prepare the cuff set of smaller size. In conclusion, if we solve those problems in our country, the artificial urethral sphincter is an effective device for treatment of urinary incontinence in patients who have failed more conservative modes of therapy.

Fetal teratomas rarely complicate pregnancy,having an incidance of only 20,000:1 to 40,000:1 of live births. Overthere, cervical teratomas are rare and accounts for only 5.5% of all neonatal teratomas. We have experienced a large cervical immature teratoma and present this case with a brief review of literatures.

OBJECTIVE: To compare the results of electrodiagnostic studies with the severity of disc herniation, measured digitally by picture archiving and communication system (PACS) from the images of magnetic resonance imaging (MRI). METHOD: MRI images were reviewed from thirty two patients who were diagnosed electrodiagnostically as unilateral S1 radiculopathy. Areas of herniated disc and spinal canal were measured and the ratio of disc herniation was calculated from the axial images stored and analyzed by PACS. The radiologic measurements were compared with the results of electrodiagnostic studies. RESULTS: The presence of abnormal spontaneous activities in needle EMG and no response in H reflex were associated with larger disc herniation (p<0.05). There was no other single electrodiagnostic study that showed correlation with any of radiologic measurements. With increasing number of abnormal electrodiagnostic tests, area of disc herniation grew larger (p<0.05). Area of spinal canal and the ratio of disc herniation did not show difference between normal and abnormal groups in most of electrodiagnostic studies. CONCLUSION: There were limited correlations between electrodiagnostic results and severity of disc herniation. The size of disc herniation, regardless of the size of spinal canal, was associated with abnormal results of electrodiagnostic tests.

Mucosal bridges of vocal fold have been described as a parallel band to vocal folds with the presence of sulcus vocalis. However, the type of mucosal bridge crossing each vocal fold has not been well documented in the literature. Herein, we present two cases of mucosal bridge found in the vocal fold connecting the mid-portions of true vocal folds. Two patients who had no history of laryngeal trauma, surgery or oro-tracheal intubation visited our clinic due to voice change. Laryngoscopic examination revealed that they had a mid-portion mucosal band without any other mucosal lesions. Two patients underwent laryngomicrosurgery with pulsed dye laser. After the surgery, they showed significant improvement of voice quality.

Purpose: The aim of this study was (1) to compare the reverse engineering technique with other existing measurement methods and (2) to analyze the effect of implant angulations and impression coping types on implant impression accuracy with reverse engineering technique. Materials and methods: Three different master models were fabricated and the distance between the two implant center points in parallel master model was measured with different three methods; digital caliper measurement (Group DC), optical measuring (Group OM), and reverse engineering technique (Group RE). The 90 experimental models were fabricated with three types of impression copings for the three different implant angulation and the angular and distance error rate were calculated. One-way ANOVA was used for comparison among the evaluation methods (P < .05). The error rates of experimental groups were analyzed by two-way ANOVA (P < .05). Results: While there was significant difference between Group DC and RE (P < .05), Group OM had no significant difference compared with other groups (P > .05). The standard deviations in reverse engineering were much lower than those of digital caliper and optical measurement. Hybrid groups had no significant difference from the pick-up groups in distance error rates (P > .05). Conclusion The reverse engineering technique demonstrated its potential as an evaluation technique of 3D accuracy of impression techniques.

PURPOSE: The aim of this retrospective study was to evaluate cumulative survival rate (CSR) of Implantium implants followed for 5 years and association between risk factors and the CSR. MATERIALS AND METHODS: A total of two hundred forty-nine Implantium Implants System (Dentium, Seoul, Korea) placed in ninety-five patients from 2004 to 2009 were investigated with several identified risk factors (sex, systemic disease, smoking, alchohol, reason of tooth loss, length, arch (maxilla or mandible), replace tooth type (incisor, canine, premolar or molar) Kennedy classification, prosthodontic type, prosthodontic design, opposite dentition, abutment type, occlusal material, occlusal unit, splint to tooth, cantilever, other surgery). Clinical examination (mobility, percussion, screw loosening, discomfort, etc.) and radiographic examination data were collected from patient records including all problems during follow-up period according to protocols described earlier. Life table analysis was undertaken to examine the CSR. Cox regression method was conducted to assess the association between potential risk factors and overall CSR. RESULTS: Five of 249 implants were failed. Four of these were lost before loading. The 5-year implant cumulative survival rate was 97.37%. Cox regression analysis demonstrated a significant predictive association between overall CSR and systemic disease, smoking, reason of tooth loss, arch, Kennedy classification and prosthodontic design (P<.05). The screw related complication was rare. Two abutment screw fractures were found. Another complications of prosthetic components were porcelain fracture, resin facing fracture and denture fracture (n=19). CONCLUSION: The 5-year CSR of Implantium implants was 97.37%. Implant survival may be dependent upon systemic disease, smoking reason of tooth loss, arch, Kennedy classification and prosthodontic design (P<.05). The presence of systemic diseases and combination of other surgical procedures may be associated with increased implant failure.
