We studied 193 Diabetics without any symptoms of coronary artery disease and 39 Normal healthy subjects as Control group, using treadmill exercise test and obtained following results. 1) The positive rate was significantly higher in Diabetics(19.4% in Normal ECG groups and 25.4% in total Diabetics)than Control groups(5.1%)(0.010.05). 5) There was no difference in HbAIC, Total cholesterol and Triglyceride between positive and negative groups(P>0.05). In summary, with exercise test, the positive rate was higher in Diabetics than in Normal control groups and it seemed to be treadmill exercise test is a useful screening method for evaluation of coronary artery disease as well as for assesment of treatment and follow up care.

Twenty four cases of acromioclavicular seperation were admitted and treated at Severance Hospital, Yonsei University from October 1964 to September 1975. Of these, six cases were subluxations and eighteen cases were dislocations. Acromioclavicular joint injury is relatively rare and there are many methods of treatment. In our cases, all the six subluxations and seven of the eighteen dislocations were treated by conservative method, while eleven of the eighteen dislocations were treated by operative method. The results of all the subluxated cases were satisfactory. In cases of dislocation, the results were considerably better in operated cases with Weavers method.

There has been increased attention given to the radial tunnel syndrome since Roles and Maudsley first described it in 1972. The occurance of radial tunnel syndrome is due to the following four anatomical causes: the fibrous bands in front of the "radial head, the radial recurrent fan" of vessels, and the tendinous margins of extensor carpi radialis brevis and of the arcade of Frohse. In these cases, the progressive paralysis of the posterior interosseous nerve was caused by the arcade of Frohse and the radial recurrent artery. The results of splitting the arcade of Frohse and dividing the radial recurrent artery have been sufficiently good in all 3 cases.

IgA nephropathy can occur rarely as a complication of D-penicillamine treatment, but it is exact pathogenesis remains unclear. If a patients has gross or microscopic hematuria during D-penicillamine treatment, D-penicillamine induced IgA nephropathy should be suspected as a cause of hematuria. In those cases, renal biopsy should be taken for diagnosis and proper management. We experienced a case of IgA nephropathy confirmed by renal biopsy in a 39-years-old female patient with scleroderma during D-penicillamine therapy and report this case with a review of literature.

Herein we report a rare case of primary esophageal malignant melanoma in a 56-year-old gentleman who presented with a 2-month dysphagea. Esophagoscopy reveals a polypoid tumor and a total thoracic esophagectomy was performed through a right thoracotomy and esophageal replacement with stomach. The tumor was proven to be a primary esophageal malignant melanoma by histological and immunohistochemical studies. The pathologic stage was IIa. He received no postoperative adjuvant therapy. He died of liver metastasis at 8 months postoperatively.

OBJECTIVE: We determined the radiographic outcome of distal radius fractures with Acu-loc volar plate. METHODS: Forty-one patients were recruited between August 2009 and September 2010. There were 10 males and 31 females, with a mean age 61.2. Fractures were radiologically classification the Frykman. Fifteen fractures were group 8, eight were group 7, ten were group 6, four were group 5 and four were group 3. Distal part of the fractures was dorsally inclined in 37 wrists and inclined to volar side in four wrists. Lateral and anteroposterior radiographs taken after operated day, the fracture were compared with radiographs of the injured wrist and the differences in palmar tilt, ulnar variance; radial height; radial shift and radial inclination were measured. RESULTS: There was significant improvement in the measurements of radial height, radial inclination, volar tilt, ulnar variance and radial shift postoperatively. The radial height improved from an average of 8.5 mm (range, 3 to 15 mm) to 11.0 mm (range, 8 to 15 mm), the radial inclination improved from an average of 21.5 degree (range, 10 to 40 degree) to 28.1 degree (range, 19 to 44 degree), the palma tilt improved from an average of 12.9 degree (range, 6 to 22 degree) to 17.2 degree (range, 7 to 27 degree), the ulnar variance improved from an average of -2.3 mm (range, -6 to 4 mm) to 1 mm (range, -3 to 7 mm) and the radial shift improved from an average of 18.7 mm (range, 15 to 26 mm) to 17.3 mm (range, 12 to 21 mm). CONCLUSION: Acu-loc volar plate is a safe and effective device.

IgA nephropathy(IgAN) is the most frequent primary glomerular disease in many countries, including Korea. The typical clinical manifestation of IgAN is synpharygitic gross hematuria, which is usually innocuous for the renal function. Some patients who developed acute renal failure coinciding with episodes of gross hematuria are rarely observed in IgAN. We have observed a 29-year-old male patient with IgAN in whom the duration of gross hematuria(total 28 days) was clearly longer than usual, inducing anemia. We report a case of IgAN associated with anemia due to persistent gross hematuria and a brief review of the literature.

The aim of this study was to measure the immediate pull-out strengths by increasing the number of suture loops and to compare the immediate pull-out strengths of three different suturing techniques. In one group, the number of suture loops increased from 2 to 9 and the suturing technique of multiple loops through the proximal ligament stumps was used. The other group, the three different techniques were transverse, vertical, and criss-cross suture. The ultimate strength for the 2 loops was 16.62 (+/-6.7)N, for the 3 loops was 34.45 (+/-12.5)N, for the 4 loops was 54.80 (+/-17.7)N, for the 5 loops was 74.30 (+/-21.4)N, for the 6 loops was 102.49 (+/-13.5)N, for the 7 loops was 105.05 (+/-24.8)N, for the 8 loops was 129.50 (+/-76.1)N, for the 9 loops was 229.50 (+/-48.7)N. The transverse suture had a mean ultimate strength of 47.38 (+/-14.8)N, where-as the vertical suture failed at 76.94 (+/-26.4)N and the criss-cross suture at 101.82 (+/-25.7)N. Consequently, their strength can be improved by increasing the number of loops and we suggest that the criss-cross suture technique is reliable method for clinical use, because of high failure strength and wider apposition area of bone to ligament.

STUDY DESIGN: A retrospective study. PURPOSE: To assess the radiographic progression of degenerative lumbar scoliosis after short segment decompression and fusion without deformity correction. OVERVIEW OF LITERATURE: The aims of surgery in degenerative lumbar scoliosis are the relief of low back and leg pain along with a correction of the deformity. Short segment decompression and fusion can be performed to decrease the level of low back and leg pain provided the patient is not indicated for a deformity correction due to medical problems. In such circumstance, the patients and surgeon should be concerned with whether the scoliotic angle increases postoperatively. METHODS: Forty-seven patients who had undergone short segment decompression and fusion were evaluated. The average follow-up period was more than 3 years. The preoperative scoliotic angle and number of fusion segments was 13.6+/-3.9degrees and 2.3+/-0.5, respectively. The preoperative, postoperative and last follow-up scoliotic angles were compared and the time of progression of scoliotic angle was determined. RESULTS: The postoperative and last follow-up scoliotic angle was 10.4+/-2.3degrees and 12.1+/-3.6degrees, respectively. In eight patients, conversion to long segment fusion was required due to the rapid progression of the scoliotic angle that accelerated from 6 to 9 months after the primary surgery. The postoperative scoliosis aggravated rapidly when the preoperative scoliotic angle was larger and the fusion was extended to the apical vertebra. CONCLUSIONS: The scoliotic angle after short segment decompression and fusion was not deteriorated seriously in degenerative lumbar scoliosis. A larger scoliotic angle and fusion to the apical vertebra are significant risk factors for the acceleration of degenerative lumbar scoliosis.

Reexpansion pulmonary edema is a rare complication of the treatment of lung collapse secondary to pneumothorax, pleural effusion, or atelectasis. But occasionally, severe morbidity and death may result. Reexpansion pulmonary edema occurs when chronically collapsed lung is rapidly reexpanded by evacuation of large amounts of air or fluid. In the treatment of the chronically collapsed lung, physicians must remember the possible events and prevent the complications. When the difference in airway resistance or lung compliance between the two lungs is exaggerated, conventional mechanical ventilation might lead to preferential ventilation with hyperexpansion of one lung and gradual collapse of the other. Differential ventilation has been advocated to avert this problem. By differential lung ventilation, we successfully treated a severe reexpansion pulmonary edema in two patients. Therefore we suggest that differential lung ventilation is the treatment of choice for severe reexpansion pulmonary edema.
