IN KJOMS and KJMPRS, Scientific and Clinical articles was 63.5% and Case reports was 36.5%. But scientific and Clinical articles was 43.4% and Case reports was 56.6% in JJOMS, 47.1% and 52.9% in AAOMS, 50.1% and 49.9% in IJOMS. 4. The number of institutes in KJOMS and KJMPRS was 46. The main 6 institute published the 57.4% of total articles. In IJOMS, Nationality of the author was composed of 42 nations. West Europe Area published 52.8% of total articles, and The dominant nation of the author were West Germeny (16.3%), U.K. (12.1%), and Japan (11.6%). 5. Authors cited 30.4 references per articles in average, but only 2.7 domestic articles was cited in KJOMS and KJMPRS. It was 17.4 references, but 9.3 domestic articles was cited. In AJOMS and IJOMS, were 19.5 and 18.0 references.

We developed an animal model to recreate the condition of an open fracture in communication with the maxillary sinus. We then studied wound healing of the sinus wall structures following fracture in the presence of autogenous bone and alloplastic implant. This model is designed to simulate the repair of an orbital floor fracture in humans. The New Zealand White rabbit was used as the animal model. Standardized 8mm defects were made bilaterally in the maxillary sinuses to include bone and mucosa in 36 rabbits. Two different implants and autogenous calvarial bone graft were placed in the soft-tissue pockets to obturate the defects, exposing one surface of the implant to the open sinus. Medpor porous polyethylene, silicone and calvarial bone implant were compared. Animals were killed at 1, 2 and 8 weeks after implantation. Gross examination of the specimens for the amount of mucosal closure and implant tissue fixation was performed. Histological sections were evaluated for bone and soft-tissue morphology juxtaposed to the implant. Complete closure of the mucosal defect was demonstrated with each type of implant. Medpor implants showed both vascular and soft-tissue ingrowth into pores by week 1. Bone ingrowth was seen by week 2. Closure of the Medpor obturated defects occurred more rapidly than in the silicone group. The Medpor implants and calvarial bone demonstrated bone and soft-tissue fixation, callus formation and maturation, while mature overlying mucosa was reconstituted over the defects. Silicone implants demonstrated a fibrous tissue reaction within 1 week of implantation and they never became fixed to bone or soft tissue. Maxillary sinus wall regeneration occurred in all defects. This study supports clinical observations of maxillary sinus wall regeneration in humans.

Minoxidil is a potent direct-acting peripheral vasodilator indicated in the management of severe or refractory hypertension. Well-known adverse effects include reflex tachycardia, fluid retention and hypertrichosis. This drug has also been reported to cause pericardial effusion in about three percent of nondialyzed patients with compromised renal function and to cause cardiac tamponade less frequently. Many studies have reported that the mean duration of therapy that caused pericardial effusion was about 8 months (range 1 month-53 months). We report a case of cardiac tamponade in nondialyzed patient with chronic renal failure receiving minoxidil for 10 years. A 58-year-old female was admitted to our hospital with dyspnea of NYHA III. She was a chronic renal failure patient without dialysis treatment and received kidney transplantation from cadaver donor and was dignosed chronic rejection in 1994. Minoxidil 10mg has been used for past 10 years. Lasix has been used for past 2 years, with dosage of 40mg to 240mg. On admission, blood pressure was 90/60mm Hg. Cardiomegaly was seen on chest radiograph. The two-dimensional echocardiogram showed a large amount of pericardial effusion. Emergency treatment with pericardiocentesis removed 2500ml of straw- colored pericardial fluid and resulted in marked improvement of dyspnea and stabilized blood pressure. The minoxidil was discontinued. The evidence of pericardial effusion was not seen for 12 months after minoxidil had been discontinued.

During 1 year and 9 month period, from September, 1980 to June, 1983, retrospective study was performed on 35 patients with Mitral Valve Prolapse at Kyung Hee University Medical Center. And the following results were obtained; 1) The mitral valve prolapse syndrome presents with various cardiovascular symptoms including dyspnea(63%), palpitation(49%), chest pain(34%), syncope and dizziness(11%). 2) Of 35 patients with MVP, 17 cases were isolated MVP, 13 cases were associated with cardiovascular disorders and 5 cases were associated with non-cardiovascular disorders. 3) Electrocardiographic abnormalities were found in 20 patients with MVP. The most common abnormality was ST-T change and atrial fibrillation, VPB, RBBB, first degree A-V block and W-P-W syndrome were also noted. 4) QTc interval prolongation was more common in serverely symptomatic patients with MVP. 5) 18 cases in 35 patients showed systolic click or murmur on phonocardiography. 6) Of 35 patients with MVP, 19 patients demonstrated prolapse of the anterior leaflet, 11 patients demonstrated prolapse of posterior leaflet and 5 patients demonstrated prolapse of the both leaflets. 7) There were severe derangement on echocardiography in severely symptomatic patients were MVP.

Purpose: To report a case of multiple retinal capillary hemangioma associated with neurofibromatosis type 1 and resulting neovascularglaucoma.Case summary: A 13-year-old boy was admitted with complaint of visual disturbance and dull pain in his left eye which had beguntwo weeks prior. Lisch nodules were observed in his left iris and corneal opacity with neovascularization of the iris and anglewere detected in the same eye. Multiple retinal capillary hemangiomas with increased tortuosity and congestion of feeding retinalvessels were observed on the upper equator of the left retina; in addition, vitreous hemorrhage was observed. There were noother abnormalities except iris mammillations in the right eye. Numerous café au lait macules were observed on the patient’s entirebody. He also exhibited axillary freckling. On brain magnetic resonance imaging, T2-weighted signal intensity was increasedin the basal ganglia, left thalamus, and cerebellar white matter; however, no vessel abnormalities were observed on magneticresonance angiography. High intraocular pressure (IOP) persisted despite the use of IOP lowering agents and IOP was normalizedafter trabeculectomy with mitomycin C administration. Conclusions This case shows that multiple retinal capillary hemangiomas can be accompanied by neurofibromatosis type 1,which may result in neovascular glaucoma.
