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.

Anterograde and retrograde conduction properties of dual AV nodal pathways were analyzed in 15 patients having no accessory pathway and showing dual AV nodal pathways during extrastimulation. Four patients in whom the supraventricular tachycardia of common type (common type SVT) was induced during electrophysiological study were classified into group A. The remained 11 patients in whom the common type SVT was not induced were classified into group B. There was a history of paroxysmal supraventricular tachycardia(PSVT) in all of group A but none of group B. Among the properties of dual AV nodal pathways, effective refractory period (ERP) of anterograde fast pathway (FP) and retrograde FP were not different in both group. Maximal AH interval of anterograde slow pathway (SP) was significantly shorter in group A than in group B (P<0.01). In group A, all patients had intact ventriculoatrial (VA) conduction, but in group B, 5 patients had no VA conduction. The paced atrial cycle length producing Wenckebach block (WBCL) and the paced ventricular cycle length producing retrograde VA block (VABCL) were significantly shorter in group A the in group B (p<0.05). There were two patients showing retrograde dual AV nodal pathways. The common type SVT was not induced in both of them probably due to long ERP of retrograde FP. In conclusion, in patients with anterograde dual AV nodal pathways, the occurrence of common type SVT is highly related to anterograde slow pathway refractoriness (WBCL) and retrograde fast patway refactoriness (VABCL).

OBJECTIVE: To evaluate of the perinatal outcome of twin gestations complicated by a single anomalous fetus. METHODS: The study included all patients with twin gestations diagnosed with a major fetal anomaly in one fetus in the second trimester during 1997-2000. Twins with anomalies in both fetuses and minor anomalies were excluded. From a total of 717 twin deliveries, there were 24 twin pregnancies with single anomalous fetus observed in Department of Obstetrics and Gynecology, CHA Hospital. Outcomes assessed included gestational age at diagnosis and delivery, antenatal complications, type of anomalies and perinatal mortality rate. RESULTS: The incidence of single anomalous fetus with twin pregnancies was 3.3% in the study population. There were 24 twin pregnancies with one anomalous fetus, and their median gestational age at delivery was 35+3 weeks (range 27-39). The incidence of preterm delivery was 54.2% (13/24) and growth restriction and respiratory distress syndrome of the normal sibling were 12.5% (8/24) and 8.3% (2/24), respectively. Eight cases (33.3%) of preterm deliveries, 3 cases (12.5%) of severe preeclampsia were noted and 2 cases (8.3%) of the pregnancies were complicated with both conditions. Regarding the type of anomalies, chromosomal anomalies and central nervous system (CNS) anomalies were the most common with 5 cases (20.8%) each. Perinatal outcomes of the normal twin and the anomalous twin were compared. There were 2 cases (8.3%) of neonatal death in the normal twin compared with 9 cases (37.5%) of intrauterine death, 9 cases (37.5%) of neonatal death in the abnormal twin. CONCLUSION: Our study shows that the presence of a major anomaly in one fetus in a twin gestation significantly increased the risk of preterm delivery and risk of intrauterine fetal death and neonatal death rate in anomalous fetus. This information may provide useful information for counseling patients about their options when faced in dilemma.

PURPOSE: To analyze the results of operative treatment for Comminuted Fracture of Distal Humerus with Transolecranon approach and Orthogonal plating. MATERIALS AND METHODS: The subjects were 22 patients with Comminuted fracture of humerus who were treated with Orthogonal plating. Patient's age, sex, type of fracture, surgical approach, method of fixation, time of operation, time of bony union, complication, range of motion were investigated, and Function of elbow was evaluated by functional evaluation of Riseborough and Radin, Mayo Elbow Performance Score (MEPS). RESULTS: Age, sex, injuried arm, operation time were not related to postoperative result. Type C2 fractures showed better results in function and range of motion (ROM) than type C3 fractures. Also early rehabilitation was important to functional recovery and ROM. The postoperative ROM was average 110. Good were 16 cases, fair were 6 cases in functional evaluation of Riseborough and Radin. Excellent were 13 cases, good were 8 cases, fair was 1 case in MEPS. CONCLUSION: Operative treatment with Transolecranon approach and Orthogonal plating showed favorable result on its function. Intraarticular comminution and early rehabilitation were closely related to postoperative function of elbow.

PURPOSE: Using magnetic resonance imaging (MRI) as the standard of reference, the purpose of this study was to evaluate the accuracy of sonoelastography (SE) for assessment of fatty degeneration of suprasupinatus (SSP). MATERIALS AND METHODS: A retrospective analysis was conducted in 131 shoulders of 126 consecutive patients who underwent shoulder MRI, and SE. Oblique sagittal images of SSP were obtained using SE; the SE images were evaluated by two orthopedic surgeons using a 256 degree color map image. RESULTS: When the supraspinatus fatty degenerations were based on MRI findings, the sensitivity of SE was 89.47%, specificity 92.85%, and accuracy 91.60%. The interobserver reliability of the SE findings was 'almost perfect agreement' with a weighted kappa coefficient of 0.81. By comparison of MRI with the SE findings, the grades of MRI and SE showed positive correlation (r=0.85, p< or =0.001). In addition, the occupation ratio and blue region area ratio also showed positive correlation (r=0.69, p< or =0.001). CONCLUSION: SE is valuable in quantitative assessment of the severity of fatty atrophy of the supraspinatus and has excellent accuracy, excellent correlation with MRI and conventional ultrasonography, and excellent interobserver reliability.
