The effect of IDU and cryocautery in the treatment of Herpes Simplex Keratitis was presented. The cryoapplicator was a model of Krwawlcz probe (2 mm in diameter) which was refrigerated in a mixture of dry ice and methyl alcohol. The applicator was appJied on the lesions 7 seconds each and antibiotics and atropine solutions were instilled. A good result was experienced in the treatment of several cases of dendritic kenititis by freezing the corneal lesions by means of cryoappJicator, which had not been responded to IDU therapy speedy. The deep neovascularization of the cornea in a case of stromal keratitis was disappeared after cryocautery for the treatment of the superficial corneal ulcers.

From September 1987 to June 1994, the authors had performed posterolateral fusion in one patient, anterior spinal fusion alone in four patients, anterior spinal fusion after posterior augmentation with Rectangle Luque and posterolateral fusion in four patients of tuberculosis of the lumbosacral junction. The purpose of this study was evaluated the reliability of the posterior augmentation with Rectangle Luque and posterolateral fusion. We divided into two groups: the study group was anterior spinal fusion after posterior augmentation with Rectangle Luque in four patients, the control group was anterior spinal fusion alone in four patients. The average follow up was obtained at 16 months(12 to 20 months) in study group, at 42.7 months in control group. Results were as follows: 1. Clinical results according to Moskowitz criteria were 2 patients with grade I. 2 patients with grade II in the study group; one patient with grade I, one patient with grade II, one patient with grade III, one patient with grade IV in the control group. Hypolordosis(less than 10 degree) at the lumbosacral junction was associated with a higher incidence of back pain. 2. Radiographically well consolidated anterior fusion was noted in all patients within average 6 months (5-7 months) in the study group and 7.2 months (5-10 months) in the control group. 3. Radiologically the lumbosacral saggital angle was corrected after operation and the mean angle was 16.5 degrees(12 to 20 degrees) in the study group, 7.2 degrees(3 to 20 degrees) in the control group. The mean loss of angular correction was 5 degrees(1 to 8 degrees) in the study group, 6.2 degrees(1 to 13 degrees) in the control group at postoperative one year follow up. In conclusion, this results suggest that the anterior spinal fusion concomitant with the posterior augmentation with Rectangle Luque is the recommendable methods for tuberculosis of the lumbosacral junction in adults.

We observed the effect of application of n-PTFE on mandibular bone defects in the rabbit. GTR is based on the hypothesis that during wound healing, non-osteogenic cells are mechanically blocked from entering a bone defect. This allows the slower-migrating mesenchymal cells from the surrounding bone and marrow, having osteogenic potential, to move the defect site. Bilateral through & through defects, 8mmx4mm in size, involving the inferior border of mandible, were created in the mandible angle of 15 rats. The experimental side was applied with high-density n-PTFE membrane, with the opposite side serving as a control. In the first week of the early experimental period, the bone defects of experimental groups were filled with highly vascularized fibrous connective tissue showing prominent osteoblastic activity with osteoid formation, whereas the defects of control were replaced by dense fibro-muscular tissue without osteoblastlf activity. After 3 weeks, the experimental group revealed well formed bone trabeculae and fibro-vascular marrow within surrounding membrane. With time the amount of new bone was decreased with increase of hematopoietic marrow, and the cortical plate composed of dense mature bone was more thicker. In the whole experimental periods, the inflammation and foreign body reaction were not found around the inserted n-PTFE membrane. After removal of membrane there was marked remodeling of newly formed bone by active osteoclasts in periosteal soft tissue, which decreased the bone volume apparently. These findings suggest that n-PTFE has biocompatibility, flexibility, and rigidity and offer rapid bone regeneration within limited area by the membrane. On the other hand, the early removal of membrane caused reduction of bone volume by the osteoclastic resorption. Thus, the time of removal may be more important factor for maintenance of regenerated bone volume.

The coexistence of spinal stenosis and scoliosis in lumbar spines is becoming a more frequent problem in elderly persons. Decreased bone mass in most of these patients also complicates their management. Recently, the pedicle screw instrumentation systems offer the way to solve these difficult problems. Most of the cases with degenerative scoliosis itself don't require surgical intervention. However, the case with severe clinical manifestations need surgery. From Jan. 1988 to Oct. 1993, authors had treated operatively for 15 cases of spinal stenosis with degenerative lumbar scoliosis. After adequate posterior decompression, pedicular instrumentation was carried out and correction of scoliotic deformity was attempted. Cotrel-Dubousset instrumentation was used in six patients, Graf instrumentation in three patients, and combined(Steffee and Graf) instrumentation in six patients. Follow up was obtained at an average of 20.4 months(Range; 10

The nevus of Ota is a benign nevus characterized by the deposition of pigment in an area of distribution of the first and second branches of the trigeminal nerve. In general it rarely causes ophthalmological problems. We experienced a 23-year-old male patient who complained sudden visual loss in the left eye with the characteristics of the nevus of Ota. On examination we found the altitudinal field defect which we believe is an unusual finding of the nevus of Ota.
