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.

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.

Teratomas are neoplasm composed of a wide variety of tissues foreign to the organs or anatomic sites in which they arise. They generally arise in gonads but a few cases are described in extragonadal sites, such as sacro-coccygeal region, mediastinum, neck, and retroperitoneum. Most sacrococcygeal teratomas are encountered in infants, particularly in neonates, and a primary sacrococcygeal teratoma is a extremely rare neoplasm in adults. Recently, we experienced two cases of presacral teratomas arising in adult, therefore we present these cases with a brief review of the literatures

Outcome measurements are essential to monitor the clinical course or the treatment response of peripheral neuropathy. Even though there are no designated standard scale for peripheral neuropathy currently, several clinical scales were validated to use for outcome measurements based on many researches. Here, we reviewed clinical scales commonly used and fulfilled clinimetric properties in peripheral neuropathy, especially focusing on inflammatory neuropathy (Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, multifocal motor neuropathy). Each scale was classified according to the International Classification of outcome measure model - the International Classification of Functioning, Disability and Health to achieve a comprehensive concept of clinical scale in peripheral neuropathy.

OBJECTIVE: Metastatic dissemination of epithelial ovarian carcinoma is thought to be mediated via tumor cell exfoliation into the peritoneal cavity, followed adhesion to and invasion through the mesothelium which overlies the contents of the peritoneal cavity. MMP-2 is secreted as a zymogen, the activation of which has been associated with metastatic progression in human ovarian cancer cell lines. METHODS: We have utilized short-term cultures to analyze the effect of specific extracellular matrix proteins, type I collagen. RESULTS: Culturing Caov-4 ovarian cell line on type I collagen led to a significant increase in conversion of the MMP-2,72kD to the MMP-2,66kD, and MT-MMP expression. MT-MMP expression correlates with expression and activation of MMP-2 during malignant progression. Altered MT-MMP expression in ovarian cell lines might contribute to MMP-2 activation, which facilitates invasion of these tumors. CONCLUSION: In summary, we found increased expression of MT-MMP that correlated with increased level of activated MMP-2 and cellular counts in chemoinvasion assay in Caov-3 cell line. But no significant increases in Skov-4 cell line on type I collagen. Conclusion: These data suggest that type I collagen induces MMP-2 activation in part by up-regulation of MT-MMP expression but has a more complicated mode of action involving additional processes.
