BACKGROUND: The aim of the present study was to determine the correlation between the amount of pain reduction after local anesthetic injection into the subacromial space preoperatively and clinical outcome after arthroscopic rotator cuff repair. METHODS: A total of 127 patients who underwent arthroscopic rotator cuff repair and followed up at least 1 year were analyzed retrospectively. Preoperatively, a visual analogue scale (VAS) for pain was measured in all patients before and after the ultrasound guided impingement test. The participants were divied into four groups according to pain reduntion ater impingement test (Group A: >75%, Group B: 50%–75%, Group C: 25%–50%, Group D: <25%). VAS for pain, shoulder range of motion, shoulder isometric strength, ASES score were evaluated preoperatively and at 3, 6, 9, and 12 months postoperatively. RESULTS: After surgery, the amount of pain reduction shows significantly at 3, 6 months in Groups A, B as compared to Groups C, D (p<0.05). Among the range of motion of shoulder joint, forward flexion was significantly improved in Group A at 3 months (p<0.05). The ASES score significantly improved at 3, 6 months in Groups A, B as compared to Group C, D (p<0.05). CONCLUSIONS: Preoperative degree of pain reduction after impingement test correlates with the improvement of pain after arthroscopic rotator cuff repair, especially in the early phase. Therefore, the impingement test could be effectively used.

The cysteine proteases of Paragonimus westermani metacercariae are involved in metacercarial excystment, host immune modulation, and possibly in tissue penetration. In order to clarify the origin of the enzymes, 28 and 27 kDa cysteine proteases in metacercarial excretory-secretory products were purified through the FPLC system using Mono Q column chromatography. The polyclonal antibodies to the enzymes were produced in BALB/c mice. Immunolocalization studies revealed that both cysteine proteases were distributed at the linings of excretory bladder and excretory concretions of the metacercariae. It was suggested that the excretory epithelium of P. westermani undertake the secretory function of metacercarial cysteine proteases, in addition to its role as a route for eliminating waste products.

BACKGROUND: This study investigated the efficacy and safety of combined subacromial and intravenous patient-controlled analgesia for control of postoperative pain after arthroscopic rotator cuff repair. METHODS: Between May 2012 and August 2014, 60 patients who underwent arthroscopic rotator cuff repair with acromioplasty and received patient-controlled analgesia were studied prospectively. Cases were divided into 2 groups: combined subacromial and intravenous infusion group (group A, 30 cases) and solitary intravenous infusion group (group B, 30 cases). The visual analogue scale was used to record the patient's level of pain every 12 hours during postoperative 72 hours and the following 48 hours after the suspension of patient-controlled analgesia. RESULTS: The mean preoperative visual analogue scale score was 7.8 in group A and 7.6 in group B, and the immediate postoperative visual analogue scale score was 7.9 and 8.1 for each group. At postoperative time (From 12 hours to 72 hours after operation), the scores of combined subacromial and intravenous infusion were significantly lower than those of solitary intravenous infusion. Significant difference in the frequency of supplemental analgesic injections was observed between group A and group B (p=0.008). However, no significant difference in complication rate was observed between the two groups (p=0.562). CONCLUSIONS: Combined subacromial and intravenous patient-controlled analgesia after arthroscopic rotator cuff repair is more effective than solitary intravenous infusion without significantly increasing complications. Therefore, combined subacromial and intravenous patient-controlled analgesia could be a effective pain control method.

BACKGROUND: Intraarticular opioids and local anesthetics may provide effective analgesia following knee arthroscopic surgery. However, there are conflicting results about the analgesic effects of a combination of morphine, bupivacaine and clonidine injected intraarticularly following knee arthroscopic surgery. The goal of this study was to determine whether clonidine added to an intraarticular morphine- bupivacaine combination provide an analgesic benefit. METHODS: Thirty patients scheduled for knee arthroscopic surgery under epidural anesthesia were selected and divided to two groups randomly. The patients in Group 1 received a combination of morphine 3 mg 0.25% bupivacaine 30 ml and patients in Group 2 received a combination of clonidine 3microgram/kg and morphine 3 mg in 30 ml of 0.25% bupivacaine intraarticularly following knee arthroscopic surgery. Postoperative pain was assessed using the visual analogue scale (VAS) and changes of arterial blood pressure, heart rate, requirement of additional analgesics, adverse effects and sedation scale were observed at 1, 2, 4, 8 and 24 hours after intraarticular injection. RESULTS: The VAS observed at 4, 8 and 24 hours after intraarticular injection were significantly lower in group 2 than group 1. Blood pressure and heart rate were not significantly changed between group 1 and group 2. The incidence of side effects, injection of additional analgesics and sedation were similar between the groups. There were no significant differences in hemodynamic changes, analgesic requirements, sedation scale or the increase of side effects between group 1 and group 2. CONCLUSIONS: The results suggest that the combination of intraarticular morphine 3 mg in 30 ml 0.25% bupivacaine plus clonidine provides significantly better analgesia than morphine 3 mg in 30 ml 0.25% bupivacaine alone following knee arthroscopy.

Horizontal tear of the meniscus occurs most commonly in older patients. The tear begins initially with a simple horizontal cleavage which divides the meniscus into superior and inferior leaves resembling a fish mouth and which may become a flap or more complex tear with time if subjected to repeated injury. Thirty-four patients(36knees/40menisci) with horizontal tear of the meniscus, treated with arthroscopic partial meniscectomy except in 3 extensive tears at Ulsan University Hospital from Jan. 1993 to Jun. 1996, were analyzed to investigate the factors that may be associated with this type of meniscal tear, and the results were as follows; 1. The tears commonly occurred in labor workers(61.7%) and without obvious trauma history(67.6%), and the average age at the time of surgery was 44 years. 2. The most common site of the tear was posterior horn of the medial meniscus (62.5%). 3. The 40 horizontal tears consisted of 12 horizontaVcleavage(30%), 3 horizontaVflap(7.5%), and 25 horizontaUdegenerative complex tears(62.5%). 4. Degenerative changes were frequently noted in both arthroscopy(69.5%) and roentgenography (72.2%).

Object: To treat hydrocephalus by ventriculo-peritoneal shunt operation, the correct positioning of the proximal catheter in the ventricle is very important. The purpose of this study was to develop the "shunt guiding kit" for the proper positioning of the proximal shunt catheter to the ventricle in the ventriculo-peritoneal shunt operation. MATERIALS AND METHODS: The "shunt guiding kit" is made of tungsten alloy and it consists of one frame, two screws and one guider. Through the guider, the proximal shunt catheter operates by mechanically coupling the posterior burr hole to the anterior target point. RESULTS: We have treated three hydrocephalus patients with use of the "shunt guiding kit", and achieved good location of proximal shunt catheters. CONCLUSION: We developed the "shunt guiding kit" for the proper positioning of the proximal shunt catheter to the ventricle, and this would be very useful for preventing ventriculo-peritoneal shunt malfunction and preventing possible brain injury during the procedures.

BACKGROUND: In patients with chronic obstructive pulmonary disease(COPD), several factors have been associated with a poor prognosis. These include old age, low FEV, low diffusing capacity, high alveolar-arterial oxygen pressure difference, and finally cor pulmonale. This study was done to investigate in the ECG signs suggesting cor pulmonale were independent prognostic factors in patients with COPD. METHOD: We analyzed ECG, pulmonary function data and arterial blood gas values in 61 patients who were admitted through the emergency department with an acute exacerbation of COPD. The ECG signs reflecting cor pulmonale were right atrial overloading(RAO), right bundle branch block, right ventricular hypertrophy and low-voltage QRS. The 61 patients were divided into 2 groups, group I with no ECG signs(n=36) and group II with one or more ECG signs(n=25) suggesting cor pulmonale. RESULTS: Poor prognostic factors by univariate analysis were low FEV1, FEV1 % pred., VC% pred., DLco, DLco % pred., PaO2 and SaO2 high PaCO2 presence of ECG signs reflecting cor pulmonale, presence of mental status change, use of mechanical ventilator, and long tern use of glucocorticoid. A multivariate analysis indicated that age(risk ratio=1.13, 95% confidence interval 1.05~1.23), Dlco % pred. (risk ratio=0.97, 95% confidence interval 0.94~0.99), PaO2 (risk ratio=0.95, 95% confidence interval 0.90~0.99) and RAO(risk ratio=5.27, 95% confidence interval 1.40~19.85) were independent prognostic factors of survival. There was a significant difference in survival between the patients with and without RAO(p=0.038). The survival rates at 1, 2, and 5 years were 94.5%. 81.4%, and 50.0% in patients without RAO and 82.4%, 70.6%, and 27.5% in patients with RAO, respectively. CONCLUSION: These results suggest that the presence of ECG signs reflecting cor pulmonale is a predictor of survival and that RAO of these ECG signs is a significant independent predictor of survival in patients with COPD.
