High septal deformities exert pressure on upper lateral cartilages and nasal bones and cause external deviation of the nose. However, detection of high septal deformities causing deviated noses is very difficult if a detailed intranasal examination is not performed. As well, the high septal border is a difficult area to approach via the endonasal rhinoplasty and is the weakest portion in the septum resulting in much difficulty in correcting deformities and in frequent later recurrence of deviation secondary to the healing process. In order to solve the above problems in 33 cases of deviated nose associated with high septal deformities, the authors evaluated deformities in the high septal border after separation of the septum from upper lateral cartilages and nasal bones. The high septal border is centralized by scoring after resection of the mid or lower-septal portion. And spreader grafts were applied to the convex sides of deviated septal borders to stabilize the high septal border and to prevent long-term recurrence of deviation. Also, to balance the traction force of side walls, the length of both upper lateral cartilages and nasal bones were equalized by resection in the longer side and grafting in the shorter side. Clinical follow-up ranged from 3 to 31 months. There was no surgical or septal complication. Also, there was no incomplete correction, recurrence of deviation, or compromized nasal support. All patients except 2 were satisfied with the aesthetic and functional results. We found that separation of septum from side walls allows detection and correction of higher septal deformities and that spreader graft allows long-term support and prevents later recurrence of deviation.

The use of a cultured autologous keratinocyte sheet has become a recognized method for the coverage of extensive bums during recent years. The disadvantages of these sheet grafts are a long time-lag until keratinocyte sheets are available, the fragility and difficulty in handling of grafts, an unpredictable take rate and extremely high costs. In this study we investigated the transplantation of cultured keratinocytes as single cells suspended in autologous fibrin glue. In a rat model with standardized full thickness wounds, this new transplantation technique was evaluated and compared directly to the conventional keratinocyte sheet grafting technique. After transplantation, wounds were evaluated for the degree of epithelial coverage, and then microscopic structures were evaluated under light and electron microscopy. The results were as follows: 1) The fibrinogen solution prepared from autologous blood had 12 times more fibrinogen compared to the original blood. 2) After transplantation of cultured keratinocyt-es in fibrin glue, the degree of epithelial coverage was 79% at 2 weeks, which was comparable to 17% for cultured keratinocyte sheet graft 3) Typical basement membrane structures were consistently found at 2 weeks after transplantation of keratinocytes in fibrin glue. 4) Rete ridges were found at 4 weeks after transplantation of keratinocytes in fibrin glue. In conclusion, the transplantation technique of keratinocytes in fibrin glue is available earlier than sheet grafts, it transfers actively proliferating cells and it simplifies the grafting procedure. As well, this technique leads to an earlier epithelial covering and an earlier restoration of the dermo-epidermal junction than sheet grafting.

The intravenous administration of midazolam is widely used as sedative premedication for upper gastrointestinal endoscopy. We performed a study to evaluate the effectiveness and safety of midazoiam as premedication for upper gastrointestinal endoscopy. Between June 1995 and October 1995, 112 patients of diagnostic esophago-gastroduodenoseopy were enrolled in the study. The patients were recieved a bolus midazolam 0.~03mg/kg or placebo, followed by typical anesthesia. The blood pressure, pulse and oximeter values were monitored. The systolic blood pressure and heart rate were increased during endoscopy in compared with before premedication, and normalized immediately. There was no significant change of arterial oxygen saturation. Midazolam induced amnesia completely in 49.2% and partially in 27.2%, and all patients were recovered completely in 1 hour. The tolerance score is higher in the midazolam group as compared with the placebo group(p<0.05), and midazolam group would accept the same sedation for repeated endoscopies(p<0.01). We conclude that midazolam has beneficial effects as premedication for upper gastrointastinal endoscopy without significant altteration in cardiopulmonary parameters. This suggest that midazolam may be used more frequently as premedication, especially in the cases of repeated endoscopy.

PURPOSE: To evaluate the therapeutic efficacy of intravitreal bevacizumab (IVB) in the treatment of branch retinal vein occlusion (BRVO) in eyes with normal tension glaucoma (NTG). METHODS: We included 16 NTG eyes and 48 age- and sex-matched eyes without NTG that had received IVB for BRVO with more than 6 months of follow-up. The main outcome measures were log MAR best-corrected visual acuity (BCVA) and central macular thickness (CMT) at baseline and 1, 3, and 6 months after IVB. We compared the results according to the comorbidity associated with NTG. RESULTS: The obstruction site of BRVO was significantly closer to the optic disc in eyes with NTG than in eyes without NTG. Baseline log MAR BCVA and CMT were similar between the two groups. After IVB, postoperative BCVA was significantly improved and CMT was significantly reduced, irrespective of the comorbidity associated with NTG. However, vision improvement was more limited in eyes with NTG, while CMT was similarly reduced compared with that in eyes without NTG. The mean numbers of injections were similar between the two groups, and there were no injection-related complications. CONCLUSIONS: IVB may have therapeutic efficacy in the treatment of BRVO associated with NTG. However, the comorbidity associated with NTG may limit vision improvement, although anatomic recovery of CMT is achieved.

Laser in situ keratomileusis[LASIK] is a refractive surgical procedure that is effective in treating myopia and astigmatism. The incidence of corneal infection after LASIK is approximately 0.02% according to international experience. We experience the case of a 20-year old man who developed endophthalmitis; corneal edema, epithelial defect, hypopyon was found 2 days after LASIK. He was immediately given intravenous and subconjuntival injection[tobramycin and ceftazidime] and topical fortified eyedrop[tobramycin and ceftazidime]. The microbiologic study revealed Serratia marcescens as the causative organism. Three days after therapy was instituted, the hypopyon resolved. After 4 months of LASIK, visual acuity was 1.0 and maintained recently. We report a case of endophthalmitis after LASIK by Serratia marcescens which detected early and treated by antibiotics. In addition, close postoperative surveillance and education for hygiene was required on early postoperative period.

With with use of Tono-pen, we investigated the degree of reduction in intraocular pressure of the Honan intraocular pressure reducer(HIPR) with preoperative use of dichlorphenamide and mannitol or without. Seventy five patients scheduled for cataract surgery were divided into 4 groups by preoperative medication. Intraocular pressure was measured before preoperative medication and in process of time after external compression with the Honan intraocular pressure reducer(HIPR) following retrobulbar injection. There was no additive effect on the reduction of intraocular pressure with the preoperative use of dichlorphenamide and mannitol. A rapid initial reduction in intraocular presure over the first 5 minutes of compression was followed by a more gradual reduction from 5 to 20 minutes. We concluded that the compression of up to 20 minutes duration without the preoperative use of dichlorphenamide and mannitol is adequate.
