This is a retrospective review of 11patients of type II SLAP lesion which were found during arthroscopic treatment of 26 patients diagnosed SLAP lesion, clinically and radiologically, hetween March l989 and June 1996. Follow-up time was averaged 26 months (range, l2 months to 72 months) and average age was 30 years old. All patients were treated arthroscopically for SLAP lesion. In type II 2 cases were repaired hy biodegradable tacks (Suretac(R)), 9 cases were repaired by transglenoid and transscapular tcchnique that included dehridement of the frayed lahrum and ahrasion of the superior glenoid neck, followed hy the placement of multiple suture on the torn capsular-labrum complex and lahrum-biccps tendon complex using suture hook, heath pin and # 0 PDS (Rhee's method). Among 9 cases with transglenoid and transscapular suture technique in type II SLAP lesion, the result were quantitated with Rowe ratin scale, 4 cases were exellent, 3 cases were good and 2 cases were fair. Our modification technique, using transglenoidal two bone hole technique and tying on scapular spine can ohtain as compatible fixation as other techniques which include metal staple, bioderadahle tacks (Suretac(R)) and anterior anchoring system such as mini-Revo. Our technique also has reasonable recurrence rate with few complication. The advantage of our modified technique is able to do superior capsular advancement, capsular plication and capsular shift which procedures are very difficult in other techniques. We propose arthroscopic transglenoid and transscapular suture technique (Rhee's method) for type II SLAP lesion as one of new method of suture for type II SLAP lesion.

BACKGROUND: Kirschner's wire (K-wire) transfixation and locking hook plate fixation techniques are widely used in the treatment of acute acromioclavicular joint (ACJ) dislocation. The purpose of this study was to compare the clinical and radiologic outcomes between K-wires transfixation and a locking hook plate fixation technique. METHODS: Seventy-seven patients with acute ACJ dislocation managed with K-wire (56 shoulders) and locking hook plate (21 shoulders) were enrolled for this study. The mean follow-up period was 61 months. RESULTS: At the last follow-up, the shoulder rating scale of the University of California at Los Angeles (UCLA) was higher in patients treated with locking hook plate than with K-wires (33.2 +/- 2.7 vs. 31.3 +/- 3.4, p=0.009). In radiologic assessments, coracoclavicular distance (CCD) (7.9 mm vs. 7.7 mm, p=0.269) and acromioclavicular distance (ACD) (3.0 mm vs. 1.9 mm, p=0.082) were not statistically different from contralateral unaffected shoulder in locking hook plate fixation group, but acromioclavicular interval (ACI) was significant difference. However, there were significant differences in ACI, CCD, and ACD in K-wire fixation group (p<0.001). Eleven complications (20%) occurred in K-wire transfixation group and 2 subacromial erosions on computed tomography scan occurred in locking hook plate fixation group. CONCLUSIONS: ACJ stabilization was achieved in acute ACJ dislocations treated with K-wires or locking hook plates. Locking hook plate can provide higher UCLA shoulder score than K-wire and maintain CCD, and ACD without ligament reconstruction. K-wire transfixation technique resulted in a higher complication rate than locking hook plate.

BACKGROUND: The effects of a newly synthesized potassium channel opener, KR-30816((-)(nitro-2-hydroxymethyl-2-methy-2H-1-benzopyran-4-y1)pyridine oxide) on the action potential of papillary muscles of guinea pigs and the ATP-sensitive potassium channel current(IKATP) of single ventricular muscle cells of rats were examined to make clear its action mechanism of the KATPchannel. METHODS: We used the conventional microelectrode and the excised inside-out patch configuration. RESULTS: KR-30816 caused a shortening of the action potential duration in dose-dependent manner, which was inhibited by glibenclamide(3microM). Before run-down of the K+channel, KR-30816 activated the cardiac ATP-sensitive K+ channel only in the presence of ATP and shifted the dose-response relation curve between [ATP]i and the channel activity to the right in parallel. After run-down of the KATP channel, KR-30816 did not after the channel opening either in the absence or in the presence of UDP. CONCLUSION: These results suggest that KR-30816 antagonizes the inhibitory effect of ATP on the KATPchannel in a competitive manner, thereby enhancing the channel openings.

We recently had a patient(46 year-old) who was to undergo resection of a pheochromocytoma. The patient was treated with phenoxybenzamine for about 2 weeks preoperatively. Thiopental was used for induction followed by N2O-O2-halothane. An endotracheal semiclosed circle absorption technique with controlled ventillatian was employed. The course of anesthesia was rather stormy, reflectedby hypertension, arrhythmia and hypotension, but the patient talerated the anesthesia and surgery well with appropriate cardiovascular control using regitine, levophed, lidocaineand intravenous fluids. Importance of preoparative preparation, sufficient sedation, smooth induction, complete analgesia, good muscuar relaxation, adequate alveolar ventillation and proper cardiovascular control has been discussed. Recently some reviews of the literature on the anesthetic management of pheochromocytoma suggest that the selection of an anesthetic agent is not as important as the adequate management of the characteristics of these agents which affect the anesthetic procedures.
