To evaluate the effects of early surgical intervention in infantile exotropia on the motor and sensory functions, we reviewed the records of 17 subjects diagnosed with exotropia before the age of 12 months, receiving surgery before the age of 24 months, with a follow-up period greater than one year, between 1996 and 2000. Of the 17 subjects (6 intermittent, 11 constant), 14 (82%) (6 intermittent, 8 constant) had a final horizontal deviation of <10 PD, with 3 (18%) needing a re-operation. Fusion and gross binocularity were developed in 7 (4 intermittent, 3 constant), and 11 (6 intermittent, 5 constant) subjects, respectively. Seven subjects developed stereopsis of 200 seconds or better, and 5 of the 6 with intermittent exotropia (83%) being involved. In conclusion, over 80% of the successful alignments were obtained with surgery before the age of 24 months in infantile exotropia, which was similar to previous studies. Furthermore, early surgical intervention, particularly in the intermittent phase, resulted in more effective sensory function.

The purpose of this study was to evaluate clinical changes in graft size after treatment with strip gingival autograft in human. 57 premolar teeth in 27 patients having the following mucogingival problems were selected. The width of extension, attached gingiva including free marginal gingiva, width of transplant and clinical sulcus depth were measured at the initial examination, 2, 12 and 24 weeks following the strip gingival autograft and free gingival autograft. The change of width of extension, attached gingiva including free marginal gingiva, width of transplant and clinical sulcus depth according to healing process in both graft procedures was statistically analyzed by repeated measure ANOVA test and independent t-test using SPSS program. The results were as follows : 1. The change of keratinized gingiva in both graft procedures was increased significantly at 24 weeks post-op. 2. The clinical sulcus depth exhibited no marked changes throughout the entire investigation in both graft procedures. 3. No dimensional variation was seen in graft size in both graft procedures. 4. Shrinkage did not differ significantly in both graft procedures. From the day of grafting to 24 weeks after surgery the percentages of shrinkage were : strip gingival autograft 28% and free gingival autograft 29%.

Recently there has been a progressive increase of thoracolumbar fractures with neurologic symptoms. It has been thought that laminectomy increased instability and was therefore considered a contraindication. Currently, with the development of instrument for posterior stabilization, it is possible to perform posterior fusion and instrumentation, both with and without laminectomy. To compare the effect of neurologic recovery with and without laminectomy, we analyzed the clinical records of 38 patients with neurologic symptoms who were evaluated with plain radiographs and CT before and after surgery from 1989 to 1996 in Gyeong-Sang National University Hospital. We divided our cases into two groups, one group consisted open reduction with laminectomy and instrumentation with posterior fusion. The other group consisted of open reduction without laminectomy and instrumentation with posterior fusion. Twenty three of 38 were operated with open reduction and internal fixation with laminectomy and others were operated without laminectomy. The results were that both groups had improvement of neurologic symptoms after surgery and at follow-up. There was no significant statistical difference between the two groups. Depending on the time interval between injury and surgery, patients who were underwent emergency surgery had an marked improvement of neurologic symptoms. Except cases of complete paraplegia, incomplete paraplegic patients who were operated within 24 hours with laminectomy group had greater improvement than those without laminectomy. The improvement was statistically significant(P<0.05).

We tested the hypothesis that the extent of necrosis at the initial MRI predicts the subsequent risk of collapse of the femoral head in a randomized clinical trial conducted to compare the core decompression to the conservative treatment. After the initial clinical evaluation including plain roentgenography and MRI, 37 hips of early-stage osteonecrosis (ON) in 33 patients were randomly assigned to core decompression group or conservative treatment group. All the patients were regularly followed by clinical evaluation including plain roentgenography and MRI at three-month intervals. The extent of ON was estimated on the basis of the percentage of abnormal signal intensity in the weight-bearing portion of the femoral head as determined on a combination in coronal aod sagittal MR images. The angle of necrotic portion in mid-coronal image (A) and that in mid-sagittal image (B) were used to quantify the extent of necrotic portion by the formula; (A/180) x (B/180) x 100%. A strong association was observed between the percentage of necrotic portion and the development of collapse. We concluded that the extent of necrotic portion is a major risk factor of the collapse and proposed a systematic method of classifying the percentage of necrotic portion, which might be useful as a predictive index for the fate of early-stage ON.

Renal angiomyolipomas are benign mixed mesenchymal tumors, which are composed of atypical blood vessel, smooth muscle and fat cells. A 34-year-old woman presented with a palpable right abdominal mass, accompanied with discomfort. A CT scan showed a large right perinephric mass, with heterogeneous density, surrounding the kidney, with enlargement of the regional lymph nodes. The presumptive diagnosis was one of a malignant tumor of the retroperitoneum, with lymph node metastasis or an angiomyolipoma, involving both the kidney and lymph nodes. A right radical nephrectomy, including the tumor, was performed. The final diagnosis was an angiomyolipoma arising from the kidney, with the dissected lymph nodes having the same pathology. There was no evidence of a tumor recurrence during the six month follow-up period. This was an unusual case of a multicentric angiomyolipoma.

PURPOSE: The goal of reduction mammaplasty is breast with natural cone shape, minimizing scars, well-placed and sensate nipple-areolar area and maintaining breast physiology. In order to satisfy that goal, variable reduction mammaplasty methods are performed, however, two methods such as vertical reduction method and inverted T-scar method are currently most used. We compared indications and advantages of the two methods and set up useful guidlines. METHODS: For 15 years from 1995 to 2010, we experienced 84 patients(162 breasts). We performed vertical reduction method as Lejour's superior pedicle technique(45 patients) and inverted T-scar method as Goldwyn's inferior dermal flap technique(39 patients). We evaluated the result of the operation comparing patient's age, amount of resected tissue, complications and post-operative scars of the two methods. RESULTS: The mean age was 36 years and the vertical reduction group was 3 years younger than inverted T-scar group. The mean breast tissue resection amount per one breast, inverted T-scar group(712 gm) was lagger than vertical reduction group(395 gm). CONCLUSION: There is no ideal method for reduction mammaplasty until now. However, we suggest that guide line, the vertical reduction method is effective for minimal and moderate macromastia in young and middle aged women and inverted T-scar method is appropriate for severe macromastia with ptosis in elderly women. Recently, all procedures tried shorter and smaller scar on the vertical line as small I, J or L shape scar, and inframammary fold as short inverted T-scar.
