BACKGROUND: The purpose of this study is to compare clinical and radiological outcomes between trans-acromial fixation with Kirschner's wire (K-wire) and AO locking hook plate fixation for acute acromioclavicular (AC) joint dislocation. METHODS: This study included 61 patients who underwent either closed reduction and trans-acromial fixation with K-wire (group A, 23 patients) or open reduction and internal fixation with AO locking hook plate (group B, 38 patients). Pain on a visual analogue scale (VAS) score, the University of California Los Angeles (UCLA) shoulder score, the American Shoulder and Elbow Surgeons (ASES) score, and active range of motion (ROM) were used in the functional evaluation. For radiological evaluation, coracoclavicular distance (CCD) was measured on both clavicular anteroposterior view and compared between groups. RESULTS: At one-year follow-up, no significant differences in VAS pain score, UCLA shoulder score, ASES score, and active ROM were observed between groups, despite five cases (22.7%, 5/23) of complication in group A. The side-to-side difference between normal and affected CCD was 2.4 ± 2.2 mm in group A and 0.2 ± 0.7 mm in group B. This difference showed a statistical significance between groups (p<0.001). CONCLUSIONS: For the treatment of acute AC joint dislocation, the K-wire trans-acromial fixation group showed a significantly greater CCD than the AO locking hook plate group. In addition, during the follow-up period, much higher incidence of complication related to implant was observed in the trans-acromial fixation group. Although clinical outcomes between groups were not significantly different, these results should be interpreted carefully.

A UPLC method has been developed in the current investigation for simultaneous determination of nine chemical markers of Bletilla striata, 4-hydroxymethylphenyl beta-D-glucoside, blestroside, dactylorhin A, militarine, dihydrophenanthrene 5, gymnoside V, dihydrophenanthrene 1, benzylphenanthrene 3 and gymnosides IX. Separation was performed at 45 degrees C on an ACQUITY UPLC BEH C18 column (2.1 mm x 150 mm, 1.7 microm) with a gradient solvent system of acetonitrile-water as the mobile phase. The flow rate was 0.3 mL x min(-1), the detection wavelength was 280 nm. The results showed that the nine chemical markers could be well resolved and that in the selected linear range, all calibration curves of the nine chemical markers showed good linearity (r > or = 0.999 3). The recoveries (n = 6) were in the range of 98.15% - 102.2% and RSDs were between 2.1% - 3.6%. The data suggested that the developed UPLC-UV method had good reproducibility, robustness, and accuracy, which was suitable for the quality control of Bletilla striata. Applications of the method showed that the nine chemical markers had higher contents in the wild B. striata than in the cultivated ones.

BACKGROUND: Superior migration of humeral head has been conventionally determined by measuring the acromiohumeral distance (AHD), We sought to devise a novel measurement system more reliably and accurately than AHD. We described a structural landmark called 'C-line'. In this study, we investigated the clinical usefulness of 'step-off of the C-line (SOC)' compared to that of AHD. METHODS: The C-line formed from the medial margin of the proximal humeral head continuing up to the inferior margin of the articular glenoid and then to the lateral border of the scapula. The superior migration of the humeral head triggered by a rotator cuff tear introduces a discontinuity in this C-line. We measured the distance of this discontinuity. We enrolled 144 patients who underwent a rotator cuff repair. We selected 58 controls who didn't have any cuff lesions apparent on magnetic resonance imaging. Using radiographs derived from standardized true anteroposterior views of the shoulder, we measured the SOC and the AHD. We used t-tests for statistical analyses. RESULTS: A rotator cuff tear was associated with an increase in SOC and a decrease in AHD. In control group, the mean SOC was 1.29 ± 1.71 mm and AHD was 9.71 ± 2.65 mm. In cuff tear group, the mean SOC was 3.15 ± 3.41 mm and AHD was 8.28 ± 1.76 mm. The mean SOCs of the patient group in relation to the mean SOC of the control group according to tear size, the SOCs of medium tear and lager groups showed statistically significant increase (p<0.05). CONCLUSIONS: The SOC may be a similarly effective to diagnose cuff tears of medium size and larger compared with AHD.

We herein report three caes of xanthogranuloma occurring in aduls representing solitary nodule or multiple papules. Blood lipid substances such as cholesterol and triglyceride were normal and extracutaneous manifestatioiis were not found in all cases. Histopathorogic findings commonly revealed a granulomatous infiltrate c(intaining foam cells, foreign body gianf. cells and Touton giant cells as well as histiocytes and lymphocytes.

Spinal anesthesia has a rapid onset and requires small doses of local anesthenc to provide reliable surgical anesthesia and good muscular reiaxation but the disadvantages are the unpredictability of upper level of block, precipitous hypotension, inability to extend the block, and the risk of postdural puncture headache. A combined spinalepidural (CSE) technique can be used to reduce or eliminate some of the disadvantages of spinal and epidural anesthesia while preserving their activity. A combined spinalepidural block may combine the reliability of spinal block and the flexibility of epidural block while minimizing their drawbacks. CSE anesthesia was performed in the 19 patients scheduled for elective total knee arthroplasty. At first 17 G Tuohy needle was inserted L2-3 interspace, the epidual space would be identified, and then a long 22 G spinal needle was introduced through the Tuohy needle until the tip of the spinal needle would penetrate the dura. The correct placement of the spinal needle was confirmed by the appearence of cerebrospinal fluid at the head of needle, then 0.5% hyperbaric tetracaine 1.6-2 ml was injected into subarachnoid space. The spinal needle was withdrawn and a 18 G epidural catheter was introduced into the epidural space. If the patients complained pain during operation, 5 ml of 2% lidocaine was injected through epidural catheter, 2.5 mg Morphine was injected into epidural space for postoperative pain control after operation. Operations were well performed under CSE anesthesia and postoperative pain controls were well managed, too. The responses of the patients who has experienced CSE anesthesia were mostly good.
