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.

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.

Choroidal metastatic carcinoma is very rare. We recently experienced a case of lung adenocarcinoma which presented to the clinic with ocular symptoms. This 57-year-old Korean male patient visited the department of ophthalmology due to decreased visual acuity and pain of the left eye. On MRI scan, a nodule was attached to the retina of the left eyeball. On simple chest radiograph, a large amount of pleural effusion was noted in the left pleural cavity. Emergency enucleation of the left eyeball was done with an impression of malignant melanoma causing an intractable ocular pain. Grossly, the lesion in the eyeball was rising from the choroid. On histologic examination, tumor cells formed many irregular, small gland-like structures. The tumor cells showed alcian blue-positive mucin in the cytoplasm and glandular lumens and were positive for CEA. Chest CT scan was performed postoperatively and showed a huge mass in the left lower lobe and multiple nodular opacities in both lung fields. Bronchoscopic biopsy revealed moderately differentiated adenocarcinoma similar to that of the eyeball.

Lipoma is one of the unusual benign breast neoplasms and usually manifests at fatty breast of women at the age of 40 to 60. We experienced a case of large breast lipoma nearly replacing the whole left breast parenchymal tissue with mammographic finding of well-defined radiolucent mass, sonographic finding of hyperechoic mass with disorganized echopattern and computerized tomographic finding of very low attenuation mass, characteristic to adipose tissue, in a young woman of her dense breast.
