The analgesic effects of music in people with glasses on perceived pain through cold-pressor task (CPT) is assessed based on three-sequence, three-period, crossover trial with three treatment conditions(music-listening, news-listening, and no-sound) to each subject. Fifty subjects are divided into three sequence groups by randomization, and CPTs under the pre-assigned treatment conditions at each period are performed. Pain responses after each CPT, subjects' pain tolerance (PT) in time scale and pain intensity (PI) and pain unpleasantness (PU) in visual analog scale (VAS) are measured. After classifying the group by whether or not to wear glasses, which is the phenotype of the myopia gene, pain responses are compared by F-tests and Tukey's multiple comparisons. CPT pain responses in group with glasses during the music intervention are significantly different from responses during the news intervention and the control conditions, respectively. This study investigates the pain responses of music intervention in the group wearing glasses, which can be seen as a phenotype of the nearsighted gene, and this result would play a role in explaining the biopsychosocial model of the pain mechanism.

Purpose: The clinical and radiographic outcomes of the internal fixation, which were executed on patients over the age of 65 with proximal humerus fracture by using a polyaxial angular stable locking compression plate (Non-Contact-Bridging proximal humerus plate, Zimmer, Switzerland, NCB), were evaluated. Materials and Methods: Thirty two patients over the age of 65 among the proximal humerus fracture treated with NCB plate, between August 2007 and January 2011, were chosen as the subjects. The average age of patients was 71 years, and the average postoperative follow-up period was 11.5 months. The fractures included 14 two-part and 18 three-part fractures. The clinical results were evaluated, using the visual analog scale (VAS) score and the Constant score. The radiological results were evaluated by time to union and Paavolainen method, which measures the neck shaft angle. Results: At the last follow-up examination, the mean VAS score was 3 points and the mean Constant score was 64.5 points, with bone union achieved after the average of 16.2 weeks following the surgery in all the cases. The mean neck shaft angle was 125.9 and 24 cases had good results, while 8 cases had fair results by Paavolainen method, at the last follow-up. There were 1 case of delayed union and cerclage wire failure, and 3 cases of subacromial impingement. There were no complications, such as loss of reduction, nonunion, screw loosening, or avascular necrosis of the humeral head. Conclusion: Internal fixation, using a NCB plate, was considered to be an effective surgical method in treating proximal humerus fracture in the elderly patients, on whom the fixation of the fracture and maintenance of reduction are difficult.

Purpose: To compare the clinical outcomes after meniscus allograft transplantation between lateral and medial or isolated and combined procedure groups. Materials and Methods: Of the patients who had undergone arthroscopic meniscal allograft transplantation between Dec. 1997 and Jun. 2007, 52 patients were available for retrospective evaluation. Patients were grouped into lateral(33 cases) and medial(19 cases) transplant groups as well as those with isolated(18 cases) and combined(34 cases) procedure. The average age was 34.2 years and the mean follow-up period was 42.2 months. Postoperative range of motion (ROM), visual analog scale (VAS), International Knee Documentation Committee (IKDC) subjective score, Lysholm score, Tegner score, patient's subjective satisfaction, $2^{nd}$ look arthroscopy and MRI were evaluated retrospectively. Results: Mean postoperative ROM was $130.3^{\circ}$. The VAS showed an improvement from 5.96 to 3.05 at the last follow up. IKDC subjective score and Lysholm score also showed an improvement from 46.5 to 64.5 and from 61.9s to 79.58 respectively. Tegner score was improved from 2.9 to 3.6. Overall, 61.5% of patients reported they were completely or mostly satisfied with procedure. There were no significant differences noted between lateral and medial groups as well as isolated and combined groups. In 2nd look arthroscopy, 10 of 18 cases showed good pheripheal healing and there were 6 cases of partial and 2 of complex tear. We observed graft subluxation or extrusion in 12 of 16 cases who were evaluated with follow-up MRI. Conclusion: Meniscus allograft transplantation alone or in combination with other procedure showed an improvement in knee pain and clinical score. But there were no significant difference between lateral and medial groups or isolated and combined procedure groups.

Purpose: The goal of this study is to evaluate the minimum three-year follow-up results of reverse total shoulder arthroplasty (RTSA) for glenohumeral (GH) arthritic and pseudoparalytic patients with severe rotator cuff deficiency. Materials and Methods: We evaluated 13 patients (three males and 10 females) who underwent RTSA from July 2007 to July 2010. The average follow-up duration was 54.2 months (range, 37~74 months). Clinical results were evaluated using the Visual Analog Scale (VAS) for pain, active Range of Motion (ROM): active forward flexion (aFF); active external rotation at the side (aERs); active internal rotation to the back (aIRb), American Shoulder and Elbow Surgeons (ASES) score, Korean Shoulder Score (KSS), and intraoperative and postoperative complications. Results: VAS score improved from 7.5(6~10) points to 1.5(0~4), and ROM of active forward elevation improved from $42.7(10{\sim}100)^{\circ}$ to $129.1(110{\sim}180)^{\circ}$. In addition, ASES score improved from preoperative 32.9 (11.7~46.7) points to 80.2(58.3~95.0) postoperatively, and KSS score improved from 36.8(24~47) points to 78.4 (61~92). Twelve out of 13 cases showed various degrees of scapular notching at the last follow-up. There was one case of intraoperative anterior glenoid fracture and two cases of temporary nerve injury. Revision surgery was performed in two cases for treatment of delayed postoperative deep infection. Conclusion: According to minimum three-year follow-up results, RTSA may be an effective treatment option for glenohumeral (GH) arthritic and pseudoparalytic patients. However, considering the possibility of complications related to delayed deep infection or surgeon's technique, RTSA should be judiciously and carefully indicated by expert surgeons.

The purpose of this study was to investigate the effect of 6 weeks' accelerated rehabilitation with anti-gravity treadmill exercise on VAS, ROM, isokinetic myofunction, and dynamic stability after surgery of modified brostrom operation in chronic ankle instability patients. The subjects of this study were 12 chronic ankle instability patients who underwent modified Brostrom operation(MBO) by the same doctor. 6 weeks' accelerated rehabilitation program is scheduled to perform for 60min, everyday, and also anti-gravity program performed for 15~30min, everyday. The visual analog scale(VSA) and significantly decreased(p<.001) and ROM in all of dorsal flexion, plantar flexion, inversion and eversion significantly increased(p<.05) after 6 weeks' accelerated rehabilitation with anti-gravity treadmill exercise. Both inversion and eversion peak torque at $60^{\circ}/sec$(p<.001, p<.01) and at $180^{\circ}/sec$(p<.001) significantly increased after 6 weeks' accelerated rehabilitation with anti-gravity treadmill exercise respectively. In muscle defect, although inversion(p<.01) and eversion(p<.001) at $60^{\circ}/sec$ and inversion(p<.01) at $180^{\circ}/sec$ significantly decreased, eversion at $180^{\circ}/sec$ tended to decrease but did not change significantly after 6 weeks' accelerated rehabilitation with anti-gravity treadmill exercise. The dynamic stability significantly increased after 6 weeks' accelerated rehabilitation with anti-gravity treadmill exercise(p<.001). These results suggest that 6 weeks' accelerated rehabilitation with anti-gravity treadmill exercise has positive effect of VAS, ROM, isokinetic myofunction, and dynamic stability after surgery of modified brostrom operation in chronic ankle instability patients. Therefore, we consider that the accelerated rehabilitation with anti-gravity treadmill exercise, which is safely and fast method, has effect on more faster recovery of ankle stability, play ground and normal daily activities.

Purpose : The voiding cystourethrogram (VCUG) is the investigation of choice in detecting the vesicoureteral reflux in urinary tract infections in children. As it is a potentially distressing and invasive test, most of the parents are so concerned about the child's stress. In this study, we compared the difference of the state of anxiety of parents before and after the VCUG. Methods : We divided 68 parents whose children underwent VCUG into 2 groups; who have given an explanation about VCUG in detail using pictures (group 1) Vs. who have given an oral explanation only (group 2). All the parents submitted the same questionnaire 2 times before and after the VCUG, which consisted of State-Trait-Anxiety-Inventory X-I (STAI-X-I) and visual analog scale (VAS) on the perception of worry, anxiety, confusion and pain. Results : Before VCUG, the perception of pain was higher in group 1 (P<0.05). After VCUG, the anxiety and confusion were significantly higher in group 2 than group 1 (P<0.05). In group 1, STAI-X-I scores, the perception of worry and anxiety were significantly decreased after the VCUG (P<0.05). In group 2, the confusion and pain were increased after VCUG (P<0.05). Conclusion : It showed that doctor's explanation on the procedure in advance may raise the perception of pain and the possibility of refusal by parents. But the STAI-X-I, worry, anxiety after VCUG were significantly decreased in group 1, while the confusion and pain were increased in group 2. Therefore we suggest that prior and sufficient explanation about invasive procedure like VCUG can be helpful in ameliorating the anxiety of the parents.

Purpose: This research was intended to evaluate the sedative effect of the music by measuring the anxiety-level, the pain-level, the blood pressure, and the pulse rate in patients who were going through extraction of the mandibular impacted 3rd molar. Materials and methods: Patients were selected among those who visited St. Vincent's Hospital in Suwon for the surgical extraction of 3rd molar from April to May, 2007 and were divided into two groups : the first, experimental group consisting of 32 people was going through extraction with the music and the second, control group also consisting of 32 people was going through extraction without the music. The anxiety-level was measured by filling out Spielberger's State-Trait Anxiety questionnaire. The pain-level was measured by VAS (Visual analog Scale). The blood-pressure and the pulse rate were recorded at waiting period, preparation and anesthesia period, 5 minutes after anesthesia, beginning of extraction and every five minutes after extraction to the end of surgery. Results: The anxiety-level was significantly lower in the experimental group than in the control group during the extraction procedure (p<0.01). The pain-level was significantly lower in the experimental group than in the control group (p<0.05). The mean systolic blood pressure was significantly lower in the experimental group than in the control group at the beginnig of extraction and 10 minutes after extraction (p<0.01, p<0.05 each). The mean diastolic blood pressure was significantly lower in the experimental group than the control group at 10 minutes after extraction (p<0.01). The mean of pulse rate was significantly lower at the beginning of extraction (p<0.05). Conclusion: The music therapy could offer not only the psychological stability but also the physiological stability during the surgical extraction of impacted 3rd molar.

Objectives: This study was performed to examine the domestic study trends on premature ovarian failure (POF) treated with Korean medicine. Methods: We investigated the studies on Korean medicine treatment for premature ovarian failure via searching 4 online databases. Results: 13 clinical studies were selected. All studies were the noncomparative studies, and mainly case reports. Studies were publicated from 2001 to 2019 and the number of studies with 1 subject was the greatest (76.9%). In accompanying symptoms, there was a study which did not report entire cases. In the 11 case reports (13 subjects), the most accompanying symptoms was hot flush (69.2%). In treatment of premature ovarian failure, the most used treatment was herbal medicine, which was used in all studies. Acupuncture treatment was used in 6 studies (46.2%) and moxibustion treatment was used in 8 studies (61.5%). The most common acupuncture point was 內關 (SP6) in acupuncture treatment, and was 關元 (CV4) in moxibustion treatment. The duration of treatment was between 1 month and 20 months, the average 7.76 months. Used outcome measurements were hormone test (84.6%), menstruation (76.9%), Visual analog sclale (VAS) (15.4%), ultrasonography (15.4%), Numeral rating scale (NRS), Body basal temperature (BBT) and Kupperman index (7.7%). In total 70 subjects, 13 subjects (18.6%) became pregnancy and 25 subjects (35.7%) had no effect. Follow up was reported in 6 studies, and the average duration of follow up was 141.63 days. Conclusions: Further clinical trials are needed to establish the evidence for Korean Medicine treatment for premature ovarian failure.

Background: Opioid delivered by epidural patient-controlled analgesia (PCA) is effective in relieving pain after surgery, but it is associated with side effects, such as nausea, vomiting, pruritus, respiratory depression, and urinary retention. The purpose of this study was to compare hydromorphone related side effects and the quality of analgesia when naloxone was added to epidural PCA regimen. Methods: Fifty-two thoracotomy patients with PCA were allocated blindly into two groups. Patients in group H (n = 26) received continuous epidural hydromorphone ($16{\mu}g/ml$) in 0.1% bupivacaine; patients in group N (n = 26) received an epidural infusion containing naloxone ($2{\mu}g/ml$) and hydromorphone ($16{\mu}g/ml$) in 0.1% bupivacaine. The basal rate of PCA was 4 ml/hr and the demand dose was 1.5 ml with a lockout time of 15 min. Pain intensity, sedation, pruritus, nausea and vomiting, respiratory depression were checked at 6, 12, 24 hours postoperatively. Results: The Visual Analog Scale (VAS) scores were significantly lower in group H than in group N. There were no significant differences in the overall incidence of pruritus, nausea and sedation between the two groups. Conclusions: Continuous epidural infusion of naloxone combined with hydromorpho-ne is not effective in reducing the incidence and severity of pruritus induced by epidural hydromorphone.
