Presurgical prosthetic treatment planning is critical for the success of the implant prosthesis. Inadequate treatment plan, due to insufficient discussion between prosthodontist, and surgeon, may result in poor prognosis. A 26-year-old male patient was referred for prosthodontic treatment after implant was placed in the area of teeth #17, 16, 22, 25 and 27, without adequate discussion nor the treatment planning between oral surgeon and prosthodontist. It was found that the patient had two hopeless teeth, and a severely resorbed alveolar ridge. Additional tooth extraction was needed and the type of definitive prosthesis was shifted from fixed type to removable one. Proper pre-surgical treatment planning is essential for the good prognosis. Implant-supported removable prosthesis on milled bars may be a useful treatment option in patients with incorrect angled placement on severely resorbed alveolar ridge.

This study was conducted to examine the effect of mefenamic acid for treatment of PDA in premature newborns. Ductus arteriosus is reopened by locally produced prostaglandin E2 in a premature newborn during hypoxia. Mefenamic acid is one of non-steroidal antiinflammatory drugs acting by inhibition of cyclo-oxygenase in the prostaglandin synthesis pathway. For three premature newborns with PDA, we administered mefenamic acid and evaluated them with echocardiography to study the effect of mefenmic acid for closure of PDA. In all three babies, ductus arteriosus was closed successfully. We feel that mefenamic acid is safe and effective medication for treatment of PDA in premature newborns, but further-study need to be conducted with larger numbers of cases to confirm this effect.

The authors evaluated the 56 patients who received the diagnosis of myopia at the department of ophthalmology in Koryo General Hospital in Seoul from May 1975 to August 1985. In this study, we reviewed the statistics of the progression of myopia with age and with the number of visits to the hospital and also the differences between male and female and left eye and right eye. The results are as follows: 1. Myopia progresses with increase of age. 2. The mean diopter of myopia over 21 years is not so remarkable compared with below 20 years. But it is not absolutely true because the number of patients are so small. 3. On the average, males are slightly higher in the degree of myopia than female, but this seems to have no statistical meaning. 4. In terms of the degree of myopia, it is higher after the age of 12 than before 12.

Gliomas of the optic nerve are relatively uncommon. We have experienced one case of glioma of the optic nerve recently. The patient was 17 year old boy who had exophthalmos and visual disturbance in his left eye for three years. The vision was CF/30cm. in his left eye and the optic nerve head was extremely atrophic. The eyeball was displaced infero-temporally. The exophthalmic value was 14mm. in right and 18mm. in left eye. On July 31, 1986, the left eyeball was exposed through Kroenlein method and the tumor mass was excised totally but the eyeball remained intact. The gross appearance of the tumor was large fusiform shape(3.5 X 2.0 X 1.8cm.) with well encapsulated grayish-white surface. The cut-section of the tumor revealed grayish-white solid area and hemorrhagic cystic area. The histopathologic slides showed that the tumor was composed of multiple pilocytic astrocytic cells in the solid area and in microcystic area. The cytoplasm of the tumor cells were bipolar spindle shape and the nucleus was uniform in general and there was no sign of mitotic figure. Numerous dense and amorphous eosinophilic materials so called "Rosenthal fibers" were also seen in the microcystic areas. Finally we have diagnosed this tumor as the Optic nerve glioma.

Accurate reproduction of intraoral tissue is essential in the fabrication of fixed prosthesis. This selection of impression material and method is very important. In this study, vinyl polysiloxane type impression material Panasil was used. Three impression methods ; one-step technique, individual tray technique, and individual tooth tray technique using the vinyl polysiloxane type bite registration material Futar Occlusion, were used to take horizontal and vertical impression. Improved stone models were fabricated. The amount of occlusal surface discrepaneies, interabutment distance discrepancies, amount of marginal defect were evaluated with the X-PLAN360d and photoscanning. The results were as follows. 1. There was no significant difference in occlusal surface according to the directions and techniques of impression taking. 2. There was no significant difference in interabutment distance discrepancies according to the directions and techniques of impression taking 3. There was no significant difference in marginal discrepancies according to the direction of impression taking but there was significant difference between one-step technique and individual tray technique, individual tooth tray technique (P<0.05). Taken together, these results suggest that individual tray technique and individual tooth tray technique are more accurate for impression taking than one-step technique.

The endoscopic variceal ligation(EVL) has been adopted as a new treatment for acute hemorrhage from esophageal varices that ranks the highest mortality rate in upper gastrointestinal tract bleedings. This treatment method has good effects for the urgent treatment and eradication of varices from acute variceal bleeding in repeated sessions. We enrolled 34 patients with an acute or chronic variceal bleeding episode at the time of admission in this study from Apr. 8, 1992 to June. 2, 1994. Among 34 patients, there were 31 males and 3 females, at ages between 45-66(mean: 52 years). The incidence of symptoms on admission was 10 in tarry stool, 9 in hematemesis 8 in ascites, 4 in hepatic encephalopathy and 3 in nonspecific symptoms. Varices were eradicated or reduced to grade I in 30(88.2%) of the 34 patients by 4-25 bands (mean: 10.8 bands) in 1-7 EVL sessions(mean: 3.1 sessions). After EVL, there are complicated by active bleeding in 3 patients, dysphagia in 3 patienta and transient chest discomfort in 5 patients but subsided during 24 hours. These results indicated that EVL is a safe method for treatment of bleeding from esophageal varices.
