Bakground : Patient-Controlled Analgesia (PCA) has become popularized for postoperative pain control. Theoretically, addition of a basal infusion would ameliorate the pain control as related to less need for additional demands. Regardless of theoretical background, usefulness of a basal infusion in PCA is controversial. Therefore, in this study we compared the analgesic consumption between PCA only and PCA plus basal infusion and assessed if the use of a basal infusion improves the analgesic efficacy in intravenous PCA. METHODS: 40 patients undergoing caesarian section, were assigned randomly to PCA only group (group 1) and PCA plus basal infusion group (group 2). Group 1 was programmed to deliver 1.5 ml of bolus infusion with 10 minutes of lockout interval and four times per hour of the maximum usage of patient control module. In group 2, 0.5 ml of basal infusion was added to the same PCA. The analgesic solution contained 60 mg of morphine, 180 mg of ketorolac and 5 mg of droperidol in total volume of 60 ml. PCA was started at the time of the peritoneal closure with 2 ml of loading dose in all patients. Postoperative assessments were pain score, sedation score, side effect, total analgesic consumption and the degree of patients, satisfaction. RESULTS: Total analgesic consumption was significantly greater in group 2 than in group 1. Pain score, sedation score, complication and the degree of the satisfaction were almost the same at all time interval in each group. CONCLUSION: We concluded that there was no significant benefit of basal infusion in intravenous PCA after caesarean section.

Percutaneous transluminal coronary angioplasty (PTCA) is often used in the management of coronary artery disease and the advances in equipment, technichal skill and acquisition of operator experiences have improved initial success rates and reduced the frequency of complications. However, acute coronary occlusion is the most common and serious complication related to angioplasty and its several potential mechanisms are intracoronary thrombus, coronary artery spasm and coronary artery dissection. Accordingly,heparinization, intracoronary thrombolysis, re-PTCA, stent implantation and emergency coronary artery bypass grafting have been previously used for reopening of an occluded coronary artery during angioplasty. In this report we describe our experience in the management of acute coronary occlusion of left anterior descending artery caused by dislodgement of thrombotic material during PTCA by means of aspiration thromboembolectomy instead of medical therapy,re-PTCA and stent implantation.

Adenoid cystic carcinoma is a rare disease of which incidence is 10-15 % of bartholins gland carcinoma. The clinical presentation is characterized by a vulval mass that existed for a prolonged period to the onset of symptoms, usually infection, pain, and burningsensation Histologically, this tumor is characterized by cribriform pattern cell growing and perineural invasion. The obtaining of clear surgical margins is the most important aspect of treatment. Here we report a case of adenoid cystic carcinoma of the Bartholins gland with a brief review of literature.

PURPOSE: A survey was performed to identify the level of mouthguard use, awareness, wearability issues and attitude toward mouthguard among elite Korean Taewondo athletes. MATERIALS AND METHODS: Survey questionnaires were given to 152 athletes participating in the Korea National Taekwondo team selection event for the 2010 Guangzhou Asian Games. Questionnaires consisted of three sections, mouthguard awareness, reasons for not wearing mouthguard and the last section to test the level of acceptance on current mouthguard and when the identified problems were resolved. For analyzing difference among response, chi2 test was used and significant level (alpha) was set up as 0.05. RESULTS: Responses in each of items showed significant difference (P<.001). Majority of response regarding each question: Majority of respondents believed that mouthguard were effective in preventing injuries (36.4%) but the result suggested that the provision of information on mouthguard to athletes was inadequate (44.0%) and the result showed that respondents were not greatly interested or concerned in relation to the mandatory mouthguard rule (31.6%). Although the responses on the level of comfort and wearability of mouthguard were negative (34.8%), athletes were positively willing to wear mouthguard if the problems rectified (51.2%). CONCLUSION: Considering the high level of willingness to wear mouthguard if the problems rectified, it is thought that together with efforts in providing more mouthguard information, the work of sports dentistry to research and improve mouthguard will be invaluable in promoting mouthguard to more athletes.

INTRODUCTION: The fixation strength of transpedicular screw system in the vertebral hody relied on bone quality and anatomical characteristics of vertebral pedicle, designs of screw and types of connection(rod or plate) with screw. The purpose of this study is to verify the biomechanical nature of the transpedicular fixation in spine under various conditions with porcine vertebrae. MATERIAL AND METHOD: Fresh porcine vertebrae and the custom-made screws were used in this experiment. To reduce the errors caused by vertebral bodies of different size and quality, vertebral bodies having regular range of pedicular width(10.0 to 11.5mm) and hone density(more than 1.0 gm/cm2) were used. The pedicle screws were inserted in the same procedure and axial pull out test was performed with using the Material Testing System(lntron8511, Canton, USA). The experiments were performed in four types to assess the difference of strength accroding to designs of the screw hy using two group of screws. The first group of screw was designed according to the outer and inner diameter and the second group was designed according to the shape, pitch, and thread profile of screw. Experiment I was perfomed to evaluate the effect of screw diameters on the biomechanical pull-out strength hy using the first group of custom-made pedicle screw which fixed all other factors except the diameter of screw. Experiment I was to verify the effect of screw shape, experiment III to verify the effect of pitch and experiment IV to verify the effect of thread profile. RESULTS: The results of experiments were summarized as follows: Experiment I showed that the screw of larger outer diameter had greater holding strength. Experiment II showed that the holding strength of cylindrical shaped screw is superior to that of conical shaped screw. Experiment III showed that there is no statistical significance between different modes of pitch. Experiment IV showed that the holding strength of buttress shape of thread profile is superior to that of V-shape. CONCLUSION: It seemed that the fixation strength of the screw was more powerful with 1 mm increment of outer diameter in 4-7mm of outer diameter, 3mm of pitch and buttress shape of thread of the screw with the same operation technique.

BACKGROUND: The SF-6D, derived from the SF-36, is a preference-based instrument measuring health-related quality of life (HRQOL). Using this tool, we measured the HRQOL of persons disabled by stroke dwelling in Gyeongju city and identified factors affecting the HRQOL. METHODS: As of March 2008, 991 persons who had had a stroke and were aged 50 and over were identified on the Gyeongju city disabled registry. Interviewers specifically trained for this face-to-face survey gathered pertinent information including general and clinical characteristics from June to October 2008. In addition, the health status was measured using the Modified Rankin Scale, the Barthel ADL index, and the SF-36. The SF-6D index was derived from the SF-36. We analyzed the known-group construct validity and convergent validity. Finally, we performed multiple regression analyses to identify factors affecting the HRQOL. RESULTS: Of the 991 potential subjects, 498 persons participated in the interviews (response rate: 50.3%). The SF-6D indices for females and those aged 70 and over were lower than indices for males and those aged 60 and less. Correlation coefficients between the Modified Rankin Scale, the Barthel index, and the SF-6D index were relatively high (-0.533 and 0.555, respectively) and statistically significant (P<0.001). Multiple regression analyses showed that sex, age, smoking, alcohol use, comorbidity, the Modified Rankin Scale, and the Barthel index had an effect on the SF-6D index of persons with stroke, and the Barthel index was the most important factor. CONCLUSIONS: Our results indicate that the SF-6D can be a valid tool for evaluating health states of persons disabled by stroke, and functional limitation was the main factor affecting the HRQOL.

A network of strands (Chiari Network) in the right atrium with attachments extending from the crista terminalis to eustachian valve and thebesian valve or sometimes to the floor of the right atrium in the region of the opening of the coronary sinus. While this congenital remnant is seldom clinically important, this membranes have been reported as site of thombus formation, and hence potential etiologies of pulmonary emboli as well as a source of entrapment of a right-heart catheter and arrhythmia. We report two cases of right atrial mass-like chiari form network incidentally detected by transthoracic echocardiography (TTE) and confirmed by transesophageal echocardiography (TEE).
