Objective : To evaluate the clinical outcome of coil embolization for unruptured intracranial aneurysm (UIA) with oculomotor nerve palsy (ONP) compared with surgical clipping. Methods : A total of 19 patients presented with ONP caused by UIAs between Jan 2004 and June 2008. Ten patients underwent coil embolization and nine patients surgical clipping. The following parameters were retrospectively analyzed to evaluate the differences in clinical outcome observed in both coil embolization and surgical clipping : 1) gender, 2) age, 3) location of the aneurysm, 4) duration of the symptom, and 5) degree of ONP. Results : Following treatment, complete symptomatic recovery or partial relief from ONP was observed in 15 patients. Seven of the ten patients were treated by coil embolization, compared to eight of the nine patients treated by surgical clipping (p = 0.582). Patient's gender, age, location of the aneurysm, size of the aneurysm, duration of symptom, and degree of the ONP did not statistically correlate with recovery of symptoms between the two groups. No significant differences were observed in mean improvement time in either group (55 days in coil embolization and 60 days in surgical clipping). Conclusion : This study indicates that no significant differences were observed in the clinical outcome between coil embolization and surgical clipping techniques in the treatment of aneurysms causing ONP. Coil embolization seems to be more feasible and safe treatment modality for the relief and recovery of oculomotor nerve palsy.

Background: Superior hypogastric plexus block has been advocated as a useful technique for the treatment of cancer related pelvic pain. The aim of this study was to evaluate the effect of neurolytic trans-intervertebrodiscal superior hypogastric plexus block for pelvic cancer pain. Methods: Twenty-eight patients with gynecologic, colorectal or genitourinary cancer who suffered intractable pain were studied. We performed superior hypogastric plexus block by trans-intervertebrodiscal approach at L5/S1 level under the C-arm fluoroscopic guide unilaterally or bilaterally. Ten ml of 100% dehydrated alcohol was injected through each needle. We evaluated the change of visual analog pain score (VAS; 0~100 mm) and daily dose of oral morphine sulphate at the time of pre-block and 7 days after the block. Results: Fourteen patients (50%) had satisfactory pain relief (VAS<30) while five patients (18%) had moderate pain control (VAS 30~60). The remaining nine patients (32%) had mild or little pain relief (VAS>60) and their daily oral morphine doses were above 160 mg. Additional pain control method may be needed for those patients who received high dose of opioid before neurolytic block. Conclusions: We conclude trans-intervertebrodiscal neurolytic superior hypogastric plexus block was effective in relieving pelvic cancer pain. Neurolytic block, earlier stage, may provide better effects for more comfortable life at the end stage for cancer patients.

Objective : The goal of this study is to present whether endoscopic release(ER) is superior to open release(OR) for the treatment of carpal tunnel syndrome(CTS). Method and Material : Fifty-nine wrists in 43 patients who had clnical signs and symptoms consistent with CTS, not responded to non-operative management, were entered into the study. Authors retrospectively compared 27 wrists treated with ER(February 1999-June 1999) with 32 wrists treated with OR(October 1997-March 1999). We performed conventional open surgery in 25 patients(mean age ; 46 years) and Brown's two-portal technique in 18 patients(mean age ; 53 years) under intravenous regional block or general anesthesia. Results : Sixteen patients had CTS on both hands and left hands were affected more frequently than right hand, 34 and 25 respectively. Successful and poor results of ER were similar to those of OR. For patients in OR group, mean duration of symptoms was 5 years(range 1 month-30 years), and postoperative outcome was good in 27(84.4%) of wrists and poor in 5(15.6%). For patients in ER group, mean duration of symptoms was 7 months (range 2 months-25 years), outcome was good in 23(85.2%) of wrists and poor in 4(14.8%). The average time for complete relief of pain was 1.3 weeks and 7.6 weeks, respectively for OR and ER groups. No complication was noted in either group. Conclusion : This preliminary analysis suggests that faster relief of pain was achieved when the endoscopic method was used, although there were no significant differences in their efficacies regarding the improvement of symptoms.

Objective: The purpose of this study was to evaluate the efficacy of spinal implant removal and to determine the possible mechanisms of pain relief. Methods: Fourteen patient~with an average of 42 years (from 22 to 67 years) were retrospectively evaluated. All patients had posterior spinal instrumentation and fusion, who later developed recurrent back pain or persistent back pain despite a solid fusion mass. Patients' clinical charts, operative notes, and preoperative x-rays were evaluated. Relief of pain was evaluated by the Visual Analog Scale (VAS) pain change after implant removal. Clinical outcome using VAS and modified MacNab's criteria was assessed on before implant removal, 1 month after implant removal and at the last clinical follow-up. Radiological analysis of sagittal alignment was also assessed. Results: Average follow-up period was 18 months (from 12 to 25 months). There were 4 patients who had persistent back pain at the surgical site and 10 patients who had recurrent back pain. The median time after the first fusion operation and the recurrence of pain was 6.5 months (from 3 to 13 months). All patients except one had palpation pain at operative site. The mean blood loss was less than 100ml and there were no major complications. The mean pain score before screw removal and at final follow up was 6.4 and 2.9, respectively (p<0.005). Thirteen of the 14 patients were graded as excellent and good according to modified MacNab's criteria. Overall 5.9 degrees of sagittal correction loss was observed at final follow up, but was not statistically significant. Conclusion: For the patients with persistent or recurrent back pain after spinal instrumentation, removal of the spinal implant may be safe and an efficient procedure for carefully selected patients who have palpation pain and are unresponsive to conservative treatment.

Purpose: This study was done to examine effects of Nei-Guan acupressure on nausea, vomiting and level of satisfaction for gynecological surgery patients who were using a patient-controlled analgesia (PCA). Methods: For this study, 51 patients were assigned to one of three groups, a control group (17 patients), experimental group 1 (finger acupressure group) (17 patients), and experimental group 2 (relief band group) (17 patients). The data were collected for 24 hr in the recovery room of a university hospital located in Seoul. The 6 hr-intervals including the time of leaving the recovery room were taken into consideration. Results: The occurrence of nausea between the experimental group with Nei-Guan acupressure treatment and the control group was different. However, there was no difference in nausea and vomiting control or level of patient satisfaction between the finger acupressure group and the relief band group. Conclusion: Nei-Guan acupressure is recommended for nursing practice as a way for alleviating the opioid-induced nausea and accelerating the recovery of patients who are using PCA after surgery.

The purpose of this study was to determine the effects of music therapy on acute, subacute and chronic pain and depression of musculoskeletal trauma patients. The study was designed using nonequivalent control group pretest-posttest design within the framework of an adaptation model. The subjects were composed of forty patients, and twenty of them were assigned to the experimental group and twenty to the control group within the unit of patients. Data were summarized as follows : 1. There were significant changes of pain scores in an experimental and a control group measured before and after the treatment. 2. There were significant changes of pulse rates, respiration rates and systolic blood pressure, but were no significant changes of diastolic blood pressure in an experimental and a control group measured before and after the treatment. 3. There were no significant changes of the amount of ${\beta}$-endorphin in an experimental and a control group measured before and after the treatment. 4. There were no significant changes of depression scores in an experimental and a control group measured before and after the treatment. As a result, music therapy was a useful nursing intervention for relief of acute, subacute and chronic pain. Two suggestions could be made on the ground of the results of this study. 1. On the basis of endogenous pain control theory, it's necessary to research the changes of the amount of ${\beta}$-endorphin as the effect of the music therapy on patients having severe pain. 2. It's necessary to research the changes of the amount of ${\beta}$-endorphin according to the lapse of time after the music therapy for pain relief.

Objectives The purpose of this study was to evaluate the most effective stimulating electrode in Microcurrent electrical neuromuscular stimulation (MENS) for pain relief, and to apply to the treatment of Delayed onset muscle soreness (DOMS). Methods We included 45 participants who met the inclusion criteria. DOMS of both Triceps Surae Muscles were experimentally induced through eccentric contractions. 24-hours after induction of DOMS, who scored more than 40 mm in visual analogue scale (VAS) were randomly assigned into three groups (n=44). In 15 of them, needle electrodes were inserted into BL57, BL56. In 15 of them, surface electrodes were applied on the same points and the others were treated with manual acupuncture. The effects of pain relief were assessed by visual analogue scale (VAS), mechanical pain threshold (MPT), surface electromyography (SEMG). Results In VAS, group comparison had no significant difference after all treatments had done. The difference in VAS between the time before the treatment was started (Day 2) and after all treatments were completed was greater in Acupuncture group than that of needle-electrode group. In MPT, there was no significant difference among groups. Electrical contraction decreased significantly at 2nd before-after treatment comparison in needle-electrode MENS group. But fatigue scores were not significantly different between groups. Conclusions The results suggest that the types of electrodes has no significant effect on microcurrent therapy in DOMS.
