Between Feb. 1992 and Apr, 1995, the authors have performed arthroscopic abrasion arthroplasty in 78 knees of 76 patients with degenerative osteoarthritis. The followup period was between 24 and 58 months, with on an average of 41 months. All patients had Zarins grade IV articular cartilage change. The results were as follows. 1. Of the total 78 knees, results were excellent in 25(32%), good in 33(42A), fair in 12(17%), poor in 8(10%) knees respectively. 2, The best results were obtained patellofemoral abrasion arthroplasty. 3. The poor results were obtained in patients with the both femoral condyle, lesion. 4. The results were much better in young age group (below 40 years). Aroscopic abrasion arthroplasty is not a curative but palliative method. But it could be an appealing altemative to total knee arthroplasty or high tibial osteotomy or can be performed postoperated after these reconstructive proeedures.

Rapid crestal bone resorption following maxillary tooth loss is further accentuated in the posterior regions because of pneumatization and enlargement of the maxillary sinuses. A treatment rationale that allows preservation and augmentation of vertical available bone at the time of posterior maxillary tooth extraction may offer numerous therapeutic benefits which are more short courses of therapy and no needs of additional surgical augmentation. The present study comprised 3 patients who had 4 posterior maxillary teeth with no evident bone between the tooth apex and sinus floor, as estimated through preoperative radiographic analysis. Sinus floor augmentation at the time of tooth extraction was chosen for the ltreatment of these patients. After the tooth was carefully extracted, the empty alveolus was thoroughly debrided and a trephine approach was performed. Particulated autogenous bone was gently pushed beyond the empty alveolus to elevate the sinus membrane using an osteotome. The distance between bone crest and sinus floor was radiographically estimated 4 months after the first procedure. Another procedure was then carried out to place the implants of 11 mm length without another augmentation procedure. All implant were clinically stable, with no sign of infection. The presented surgical procedure performed at the time of extraction of posterior maxillary teeth in close proximity to the sinus floor allowed placement of implants of proper length.

Plexiform neurofibroma is considered a pathognomic of Von Recklinghousen's disease, which involves the deep and large nerve trunk. These are large irregular nerve fascicles which result from an increase in endoneural matrix within individual nerve facicles, without an increased number of nerve fibers. We experenced a case of Von Recklinghausen's disease in a 24 year-old male who had variable cutaneous skeletal, and CNS lesions. He presented multiple neurofibromas, cafe-au-lait spots, and axillary freckles as common cutaneous lesions of NF-I and giant pigmentation, sacral hypertrichosis, and plexiform neurofibroma as unusual cutaneous lesions. Also he had a scoliosis, bowing deformity of the humerous and wedging deformity of the body of the 5th cervical spine as a skeletal manifestation and cortical calcification in the occipital area as a CNS manifestation.

Cavernous hemangioma of the renal pelvis is a rare benign vascular tumor. We experienced a case of this disease, which associated with renal infarction and hemorrhage in 35 year-old female. I. V. P, R. G. P and abdominal C. T were performed. Now, we introduced the pathologic and radiographic findings.

BACKGROUND: 1. Conventional topical treatments of alopecia areata such as intralesional injection and topical application of glucocorticosteroids, and induction of conttact sensitivity using DPCP have had dieadvantages as follow 1) a time -consuming treatment perioed 2) various forms of discomfort during and after treatment 3) many side effects. 2. Though hair follicllee are easily damaged by intense cryo-application, we anticipate the regrowth of hair without damage to the tissue when applied to the scalp lightly OBJECT: We evaluated the efficacy of treatment and side effect of cryotherapy in patients with alopecia areata and whether this method can be used for the firstiline treatment of small alopecic patches, avoiding the above disadvantages of conventional methods METHOD: 19 patients witt alopecia areata lesion(s) confined within one fourth of the totaI scalp area were treated by dip-stick method with liquid nitrogen once a week luring the first 4 weeks, then at a two week interval. A cotten tip was lightly applied to the alopecic, patches for one to two seconds. We surveyed side effects and regrowth of hair during a periodic follow up. RESULT: The results can be summurized as follows : 1. Therapeutic responses were noted in 17(89%) of 19 patients studid. 2. In all the patients who responded, vellus hair appeared within 4 weeks of treatment, and terminal hair appeared within 6 weeks of treatment. 3. There were no specific fectors showing statistical significance between therapeutic responses. 4. There were no significanf, side effects except very faint pain during cryoapplication. 5. Recurrence was observed in only patieni during a 9-12 months follow-up CONCLUSION: Cryotherpy of the alopecia areata can be regarded as an effective mode of treatment with many advantages. These include relatively good therapeutic results, short-term treatment, a simple and convenient method, and nearly no side effects. We recommerld cryotherapy as a first-line mode of treatment of alopecia area.ta lesions which are small in size and few in number.

From 1986 to 1995, 75 eyes of 75 patients who were admitted with a diagnosis of infectious corneal ulcer at Chunbuk university hospital were analyzed on the etiologic agents and clinical findings. Etiologic agents of infectious corneal ulcer were classified as 49 bacterial ulcers(65.3%) and 26 fungal ulcers(34.7%). The most common isolated bacteria was 8 cases of coagulase negative staphylococcus and pseudomonas species was the most common isolated gram negative organism. Candida species was the most commonly isolated fungus. Hypopyon was noted in 30 cases(40%) of infectious corneal ulcers, 14 cases in small ulcer group and 16 cases in large ulcer group. There was no difference between severity and presence of hypopyon of the 75cases (P>0.05. chi-square test).

PURPOSE: To evaluate the causes of failed dacryocystorhinostomy (DCR) and the effects of transcanalicular diode laser-assisted endonasal revision surgery according to the number of silicone tubes. METHODS: Sixty-seven patients (70 eyes) who underwent revision surgery using transcanalicular diode laser for failed primary endonasal DCR at Sungmo Eye Hospital between March 2007 and December 2012 were studied retrospectively. The causes of failed DCR and the time of recurrence were evaluated. The revision surgeries were endoscopic removal of granuloma and membrane and synechiolysis with intubation of 1 or 2 silicone tubes. We compared the results of revision surgery with 1 silicone tube and 2 silicone tube intubations. RESULTS: Recurrence occurred after a mean duration of 4.6 months following the first DCR. The causes of surgical failure were granuloma (35 eyes), membranous obstruction (23 eyes), synechia (7 eyes), and functional obstruction (5 eyes). We performed revision surgery with 1 silicone tube intubation in 45 eyes (group A) and 2 silicone tube intubations in 25 eyes (group B). The final success rates in groups A and B were 75.6% (34/45) and 84% (21/25), respectively (chi-square test, p = 0.828). CONCLUSIONS: Transcanalicular diode laser-assisted endonasal revision surgery with 2 silicone tubes is not recommended.

Takayasu's arteritis is the chronic inflammatory panarteritis of unknown pathogenesis, affecting aortic arch and main arotic branches, pulmonary and renal arteries. It mainly affects young oriental women and cause chronic ischemic injury to tissues of the brian, orbits, upper limbs, myocardium, and kidneys. The ophthalmologic features are tend to be late the manifestations of Takayasu's arteritis and include ischemia of the retina, choroid, and anterior segment. We experienced two cases of Takayasu's arteritis whose ipsilateral ophthalmic artery was completely occluded. yet maintained proper visual acuity by external carotid-ophthalmic anastomosis.
