Lumbar spinal fusions have been performed for spinal stability, pain relief and improved function in spinal stenosis, scoliosis, spinal fractures, infectious conditions and other lumbar spinal problems. The success of lumbar spinal fusion depends on multifactors, such as types of bone graft materials, levels and numbers of fusion, spinal instrumentation, electrical stimulation, smoking and some drugs such as nonsteroidal anti-inflammatory drugs (NSAIDs). From January 2000 to December 2001, 88 consecutive patients, who were diagnosed with spinal stenosis or spondylolisthesis, were retrospectively enrolled in this study. One surgeon performed all 88 posterolateral spinal fusions with instrumentation and autoiliac bone graft. The patients were divided into two groups. The first group (n=30) was infused with ketorolac and fentanyl intravenously via patient controlled analgesia (PCA) postoperatively and the second group (n=58) was infused only with fentanyl. The spinal fusion rates and clinical outcomes of the two groups were compared. The incidence of incomplete union or nonunion was much higher in the ketorolac group, and the relative risk was approximately 6 times higher than control group (odds ratio: 5.64). The clinical outcomes, which were checked at least 1 year after surgery, showed strong correlations with the spinal fusion status. The control group (93.1%) showed significantly better clinical results than the ketorolac group (77.6%). Smoking had no effect on the spinal fusion outcome in this study. Even though the use of ketorolac after spinal fusion can reduce the need for morphine, thereby decreasing morphine related complications, ketorolac used via PCA at the immediate postoperative state inhibits spinal fusion resulting in a poorer clinical outcome. Therefore, NSAIDs such as ketorolac, should be avoided after posterolateral spinal fusion.

The common errors in preoperative treatment plan for the orthognathic surgery can be occurred during cast impression, cast mounting procedure with face-bow transfer, surgical stent fabrication, and so on. One of the most common errors exists during mounting process of the model on the articulator. Accurate mounting of dental casts to articulator should be achieved by transferring the 3- dimensional spatial relationship of the maxillary arch to an articulator. A face-bow is used for transfer this relationship to articulator, usually by relating the face-bow to a plane of reference of maxillary cast. The purpose of this study is evaluation of the accuracy of face-bow transferring of maxillary model to the articulator. The maxillary casts of thirty patients for orthognathic surgery were mounted on articulator with an face-bow instrument. The relationship of occlusal plane angle to Frankfort horizontal plane relations were compared the cephalogram with the cast-mounted articulator. As a result of this study, the significant difference between the maxillary occlusal planes angle in the cephalogram and articulator were found . The results were followed,1. The mean occlusal plane angle in cast-mounted articulator was 13.5.(SD+/-5.4).2. The mean occlusal plane angle in cephalogram was 10.4.(SD+/-4.3).3. The mean difference of occlusal plane angle between cast-mounted articulator and cephalogram was 3.3.(SD+/-4.6).According to the result, we should suggest that the occlusal plane angle to Frankfort plane in cast-mounted articulator is more steeper than that of cephalogram.And then, maxillofacial surgeon should try to get a more predictable result by suggesting the proper correction method and mounting the cast accurately.

Despite a recent trend toward increased screening and public awareness for colorectal cancer, 30% of patients present with incurable disease. This study was designed to identify objective criteria that might help surgeons decide which patients with incurable colorectal cancer will benefit from palliative resection. Among 33 patients considered incurable colorectal cancer, twenty one patients underwent palliative resection and twelve patients had bypass surgery. Incidence of postoperative complication after palliative resection was 61.9%(13 cases), and after bypass surgery was 58.3%(7 cases). Among patients treated by palliative resection, one patient required reoperation for postoperative bleeding. The operative mortality after palliative resection was 19%(4 cases), and after bypass surgery was 25%(3 cases). The median survival was 11.4 months for patients treated by palliative resection, and was 9.7 months for patients treated by bypass surgery. These results show that palliative resection can be done safely and effectively in patients with incurable colorectal cancer. We believe this approach improved the quality of the remaining life in these patients.

We present a case of angiographically-confirmed transverse and sigmoid sinus thrombosis, image with MR, in a 20 year old male with a history of otitis media and maxillary sinusitis. T1-weighted image demonstrated an isosignal intensity mass with tubular-shaped low signal intensity in right transverse and sigmoid sinus. The thrombus had high signal intensity on T2-weighted image. The signal intensity of the thrombus on Gd-DTPA enhanced T1-weighted image was unusually high similar to that of transverse sinus. Although dural sinus thrombosis has a non-specific MR signal intensity, findings of MRI in this case may serve as an aid in future evaluation of venous thrombosis.

BACKGROUND: One of the most, probable pathogenesis of vitiliga is autoimmune. Systemic cor tico st,eroids suppress immunity and may arrest the progression of vitiligo and lead to repigmentation. OBJECTIVE: We have assessed the clinical effect of a oral small oral dose of corticosteroid to minimize side effects in vitiligo patients. METHODS: Thirty four patients(9;male, 25;female) with vitiligo were evaluated in this study. The patients took 7.5mg-20mg prednisolone initially for 2 months and then the dosage was tapered to half of the initial dosiat the 3rd month and half of dose of 3rd month for the last 4th month. We compared the effcct of treatment of vitiligo before and aft.er the study by photographs. and side efferts were issessed at. 1, 2, 3 and 4 month. RESULTS: The arrest of the progression of vitiligo was noticed in 79% of patients and repigmentation was noticed in 59% of patients which is statistically significant. The effect, of treatment according to extent, duiation, type, and site of vitiligo were not statistically significant. The side effects of treatment were minimal and did not affect the course of treatment. CONCLUSION: Small doses of iral corticosteroids are effective without any significant side effects in preventing progression and loiiduce repigmentation of active spreading vitiligo and generalized type of vitiligo that is difficult to treat with topical corticosteroids.

From January 1993 to December 1995, 47 patients with rectal carcinomas underwent a rectal anastomosis using the double stapling technique at the Surgical Department of Kwang-ju Christian Hospital. The major advantages of the double stapling technique for lower rectal cancer over the single stapling technique or a hand-sewn operation are as follows:1) Insertion of a purse-string suture is eliminated, and application of a linear stapler to close the distal rectum may be performed with greater ease. 2) In addition, fecal contamination and spillage of tumor cells from the rectal segment are minimized. 3) Differences in the sizes of the colons and rectums are not a concern in constructing the anastomosis. 4) The operating time is shorter. The following results were obtained by a comparison with 24 patients with rectal carcinoma who had undergone a rectal anastomosis using the double stapling technique from January 1989 to December 1992 which was reported in a previous study:1) Anastomotic stenosis was decreased from 8.3% to 4.2% because of reduced ischemia due to the double row of staples and the reduced injury due to compression of tissue between the anvil and the cartridge with experience. In addition, it resulted from reduced tension of the anastomosis due to sufficients mobilization of the proximal colon and from selection of large cartridge (33 mm). 2) Anastomotic leakage, even though the same location as the tumor and in the advanced age group, was decreased from 4.2% to 0% because the blood circulation was maintained and unnecessary tension was reduced with experience. In addition, it resulted from reinforced suture of the anastomotic site which was performed after anastomosis. 3) Systemic recurrence was the same result as that of the previous study(4.2/4.3%). 4) Local recurrence, even though at the same distal distance from the margin of the cancer, was increased from 0% to 2.1% because of advancing the pathologic stage (B2, C1>B1, B2) and increasing the poorly differentiated pathologic type.
