The orbital blowout fractures has been increasing due to trauma and traffic accidents with time. The diagnostic confirmation is easily established by CT scan, but the indication for surgical treatment, the technique for repair, and timing of repair are still controversial. We have reviewed investigated the charts of 18 cases who had blowout fracture, including the clinical manifestation, surgical indication, surgical procedures, improvement of diplopia, and its complication. The follow up was at least 6 months in the past 5 years. In cases of diplopia only in the upward gaze limitation, or small orbital fracture in orbital CT scan and less degree of enophthalmos, these 8 cases were treated conservatively for 2 weeks and diplopia improved markedly. However, in 10 cases of severe diplopia and in large fracture and tissue incarceration, these were surgically managed using Silastic sheets. In these cases, the diplopia resolved within 1 month in 7 cases(70%). Residual diplopia waS seen in 3 cases, and we retreated surgically for the two cases of them. In the other non surgical cases, diplopia resolved on 6 months follow up except in 2 cases of mild diplopia. Therefore we should pay more attention to surgical indication.

Branch Retinal Vein Occlusion(BRVO) is the second most retinal vascular abnormality after diabetic retinopathy. Systemic hypertension is the most common combined disease. The author evaluated 38 patients of BRVO with hypertension regarding the clinical manifestations, viual acuity changes and the results of treatment. Medical or Laser therapy was selected according to the degree of retinal nonperfusion, macular edema and neovascularization documented by fluorescein angiography. The most common age group was sixth decade(39.5%) and the most common affected site was superior temporal branch of retinal vein(60.5%). The sequelae were macular edema(39.4%), perifoveal non perfusion, retinal neovascularization and vitreous hemorrhage. There were no significant differences in visual prognosis due to the states of blood pressure, vein occlusion site and timing of laser therapy. The better visual prognosis was observed in cases of without soft exudate or without macular edema or capillary non perfusion less than 5 disc diameter. The increased visual acuity of 2 lines or more were noted in 10(71%), 13(76%), 9(60%) cases respectively and showed stastiscal correlations(p<0.05). The visual improvement in 11 cases(55%) who has broken capillary ring were no significant statistical differences(p>0.05). We suggest that the medical and laser therapy should be considered according to the status of high quality fluorescein angiography of retina.

The blepharoptosis is drooping of upper eyelid in primary gaze with various causes. The most common cause of ptosis is, in known as, underdevelopment of levator muscle. We evaluated the age and sexual distribution, clinical manifestation, result of treatment and it's complication of congenital blepharoptosis. The method of surgery and amount of muscle resection was decided according to several factors that is the amount of ptosis, the preoperative levator functon, and the Margin Limbal Distance(MLD). Most of patient was second decades(48.3%). In cases of unilateral ptosis, left lid was higher incidence(60%) than right lid and 4 cases(14%) were bilateral ptosis. The amount of ptosis was between 3 and 4mm in most cases(48.5%), and over the 5mm was 12 cases(36.3%). Preoperative levator function between 4 and 7mm of the patient was in 18 cases(54.5%) and 3mm or less was 12 cases(36.3%). Between 16 and 19mm muscle resection was 10 cases(43.5%), Between 12 and 15mm resection was 7 cases(30.4%). In initially corrected visual acuity with Hans Chart. 12 cases(36%) were 0.5-1.0 and 2 cases were 0.1 or less. There is no significant visual improvement after one year surgical correcton. The most common surgical procedure was levator muscle resection(73%) through anterior skin incision and followed by frontalis suspension in 9 cases(27%). The result of operation was good for the period of six months follow-up. The most common complication was undercorrection in 2 cases of levator muscle resection and 1 case of frontalis suspension. The other complications were overcorrectopn, exposure keratitis and entropion in each case, respectively.

Tuberculous menigitis is relatively common disease and delay in treatment is associated with many neurologic sequelae. Of the neurologic disorder, diabets insipidus is extreamly rare. Diabetes insipidus is a syndrome characterized by the excretion of abnormally large volumes of dilute urine. It is divided into central diabets insipidus, nephrogenic diabetes insipidus, primary polydipsia and gestational daibetes insipidus. In this four type of diabetes insipidus, central diabetes insipidus is a polyuric disorder results from a lack of sufficient antidiuretic hormone to effect appropriate concentration of the urine for water conservration. We report a 25-year old male who had prolonged head ache and subsequently followed by polyuria. He was dia gonsed as the tuberculous meningitis by laboratory find ing and smear of CSF, and diagnosed central diabetes insipidus by serum osmolality & Na+ & AVP (arginine va sopressin), urine osmolality & specific gravity, adminis tration of vasopressin. He maintained the water balance of body by administration of vasopressin, but without im provement of mental status, sudden cardiac arrest occurs on 20th hospital day

The purpose of this study was to investigate whether the densities of antral gastrin and somatostatin-immunoreactive cells in Helicobacter pylori (H. pylori) infection were related to the bacterial expression of cytotoxin-associated gene A (CagA). 32 patients who had underwent diagnostic esophagogastroduodenoscopy were studied. On the histologic examination all patients had antral gastritis. We divided the subjects into three groups. Group I consisted of 6 patients who had chronic superficial gastritis, group II, 9 patients who had H. pylori-associated gastritis but with no expression of CagA, and group III, 17 patients who had H. pylori-associated gastritis with the expression of CagA. In group I and II, serum gastrin levels, and antral G cell and D-cell were measured. In group III, serum gastrin levels, and antral G cell and D-cell were measured, before and after the eradication of H. pylori. The results were as follows. Firstly, serum gastrin concentrations were significantly higher in the patients with H. pylori infection than in the negative controls. Nextly, there was no correlation between the changes in antral G or D-cell density and H. pylori infection. Thirdly, group III had a significant increase in serum gastrin concentrations and a significant decrease in antral D-cell density than group I. Forthly, eradication of H. pylori in group III showed a significantly increased antral D-cell density. Our results suggest that hypergastrinemia in H. pylori-associated gastritis is relevant to the presence of CagA, and the possible mechanism of hypergastrinemia may be related to antral D-cell deficiency, which is caused by H. pylori infection with the expression of CagA.

The use of digital technology in fixed prosthetic treatment using implants enables predictive treatment through diagnosis and virtual surgery by integrating clinical and radiological information of patients. Existing digital scanning methods require several components to be removed, such as removing the healing abutment and connecting the scan body. In the scannable healing abutment developed in consideration of this point, scanning is performed directly on the healing abutment, maintaining soft tissue sealing and simplifying scanning. Digital technology can also be used when obtaining the intermaxillary relationship. Recently, various digital technologies have been reported to acquire the intermaxillary relationship of edentulous patients using surgical guides, patient-specific scanning devices, or scans of the inside of temporary dentures. In this case, the implant-supported fixed prosthesis treatment was performed through scanning the scannable healing abutment and the inner side of the temporary denture to obtain the intermaxillary relationship, thereby simplifying the treatment process and obtaining aesthetically and functionally excellent clinical results.

PURPOSE: The purpose of this study is to fabricate the new zirconia block (CNU block) and to evaluate fit of core and porcelain veneered zirconia crown. MATERIAL AND METHODS: The experimental blocks were fabricated from the commercial ytrria-stabilized zirconia powder (KZ-3YE Type A). The powder was uniaxial pressing and the green bodies were conducted using the Cold Isostatic Pressing. The zirconia blocks were presintered at 1040degrees C and the final sintering was performed at 1450degrees C. The Kavo Everest ZS blank(R) (KaVo, Biberach/Ri beta.) was used as a control group. The linear shrinkage of CNU block and Kavo block were compared. Twenty-one cores for porcelain veneered crowns were fabricated with CAD/CAM system (Everest(R), Biberach/Ribeta.). Group I: seven cores fabricated from Kavo blocks, Group II: seven cores fabricated from CNU blocks, Group III: seven cores from CNU blocks and porcelain veneering for crowns. All specimens were cemented and sectioned into two planes: diagonal and bucco-lingual. The measurement of the marginal, internal, and occlusal fit was carried out using SEM (S-4800(R)) at 30 x. The results were analyzed by one-way ANOVA test. RESULTS: The linear shrinkage of the CNU block and the KaVo block was 19.00% and 20.09%. The marginal gap of cores (29.67 +/- 6.58 micrometer) fabricated from CNU blocks showed significantly smaller than that of the cores of Kavo blocks (36.84 +/- 7.18 micrometer) (P < .05). The internal gaps of the porcelain veneered crowns (32.23 +/- 6.33 micrometer) were larger than those of the other two groups (37.57 +/- 6.81 micrometer and 38.14 +/- 6.81 micrometer). CONCLUSION: No statistically significant difference was found in between experimental groups and control group. The experimental groups in marginal gap showed significantly smaller than the control group.
