A retrospective study was done to analyze the clinical characteristics about herpes simplex keratouveitis. We reviewed medical records of 28 patients who had been diagnosed as having herpes simplex keratouveitis at Hanyang University Hospital from May 1987 to January 1998. Mean follow-up period was 14 months. In 28 patients(male 19, female 9), first attack was in 5 patients, recurrent uveitis in 16 patients, and 7 patients were undetermined due to lack of detailed clinical history, Stromal keratitis(intersititial keratitis, kisciform keratitis, and necrotizing keratitis) was present in 23 eyes, superficial keratitis(dendritic keratitis, geographic eyes. Ten eyes had an increased intraocular pressure of 21mmHg or more, with 5 eyes having 31mmHg or more, which were all in cases of recurrence. Posterior synechiae were present in 9 eyes, iris atrophy in 4 eyes. Herpes simplex keratouveitis is prone to recur and frequently associated with herpes simplex keratitis, especially stromal keratitis. It may be associated with increased intraocular pressure, osterior synechiae, iris atrophy, or hypopyon, Therefore it is necessary to follow up persistently.

Bleeding that recur or continues after hospital admission for an acutely bleeding peptic ulcer is the single most important factor adversely affecting prognosis. The endoscopic findings of stigmata of recent hemorrhage such as active bleeding, a visible vessel or fresh blood clots in peptic ulcer indicate relatively high rebleeding risk. 30 patients with stigmata of recent hemorrhage in bleeding peptic ulcers were treated by endoscopic alcohol injection therapy during the 3-year period from August 1989 to July 1992. 30 cases included 24 gastric ulcers, 4 duodenal ulcers, and 2 stomal ulcers. 8 of these were actively bleeding at the time of endoscopy and non-bleeding visible vessels were identified in 15 patients and fresh blood clots were present in 7. 12 of total 30 cases had rebleeding or continuous bleeding. 3 of 8 with active bleeding, 5 of 15 with non-bleeding bisible vessels, and 4 of 7 with fresh blood clots had rebleeding. Emergency operations were done in 4 cases. There was no complication such as perforation and mortality. We think that this modality of endoscopic hemostasis is safe and simple, but further randomized controlled trials will be needed to evaluate the efficacy of hemostasis by endoscopic alcohol injection therapy.

Mini implants had been used provisionally for the healing period of implants in the beginning. But it becomes used for the on-going purpose, because it is simple to use, economic and especially suitable for the overdenture. But there is few studies about the stability of mini implants, that is most important factor for the on-going purpose, and particularly the implant parameters affecting the initial stability. The purpose of this study was to evaluate the stress and the strain distribution pattern of immediate- loaded screw type orthodontic mini-implant and the parameters affecting the initial stability of immediate-loaded mini-implant. Two dimensional finite element models were made and contact non-linear finite element analysis was performed. The magnitude and distribution of Von Mises stresses were evaluated. The obtained results were as follows: 1. The stress was concentrated on the thread tip of an implant in the cortical bone. 2. The direction of load is the most important factor for the stress distribution in cortical bone. 3. The diameter of an implant is the most important factor for the stress distribution in the trabecular bone. In conclusion, if the horizontal load vector is successfully controlled, mini-implants, which diameter is under 3mm, can be used for the on-going purpose.

OBJECTIVE: Seoul National University Bundang Hospital is the first full digital hospital with electronic medical record(EMR) system in Korea. We evaluated the user's satisfaction on the EMR system at 15 months from its beginning. METHODS: A total of 105 doctors and 503 nurses participated in this study. The questionnaire was composed of four domains: user satisfaction between paper records and EMR, User perceived improvement of work efficiency with EMR, user interface satisfaction and advantage/ disadvantage of EMR. A Likert-type 5-point scale was used for the degree of satisfaction, with 5 indicating 'very satisfied'. RESULTS: Doctors were more satisfied with EMR system than paper records, especially on editing (3.33 vs. 2.73, p<0.05) and retrieval (3.68 vs. 2.23, p<0.05). However, the degree of satisfaction was not significantly different from that of paper records in terms of input (3.22 vs. 3.03, p>0.05). Nurses were more satisfied with EMR system than paper records, e.g., editing (3.51 vs. 2.74, p<0.05), retrieval (4.07 vs. 2.51, p<0.05) and input (3.82 vs. 2.90, p<0.05). Also, doctors and nurses showed satisfaction for most of user interfaces. CONCLUSION: Users seem to be satisfied with the EMR system. EMR system should have a flexible system to improve the input system, the structured forms, and the standardized terminology according to the need of users.

BACKGROUND: Abdominal obesity is recognized as an important risk factor of metabolic diseases and atherosclerosis. The purpose of this study was to investigate the effects of vibration baths on abdominal fat and blood lipid profiles in obese women. METHODS: From Apr. to Jun 2000, the 32 obese women received vibration baths for 4 weeks (30 minutes/day, repeated 5 times per week). The people were divided randomly into two groups, the case (n=17) and the control (n=15) group. The case group received vibration baths (55 Hz) and the control group took baths only. Body weight, height, body mass index (BMI), body fat distribution, lipid profiles, and blood pressures were measured in all subjects immediately before and after 4 weeks of the study. The body fat distribution was assessed by CT scan by which both total abdominal and visceral fat areas were measured at the level of the umbilicus. RESULTS: After 4 weeks, 13 subjects remained in both groups, respectively, and the total abdominal and visceral fat area decreased significantly in the case group compared from those of the control group. There were no significant differences in body weight, body fat mass, serum lipid profiles, and blood pressures before and after the baths in the two groups. CONCLUSIONS: These results suggest that vibration baths is effective in decreasing abdominal fat. But there were no significant weight change, the effect is insufficient in obesity treatment goal.

BACKGROUND/AIMS: Biliary stricture is the most common and important complication after right-lobe living-donor liver transplantation (RL-LDLT) with duct-to-duct biliary anastomosis. This study evaluated the efficacy and long-term outcome of endoscopic treatment for biliary stricture after LDLT, with the aim of identifying the factors that influence the outcome. METHODS: Three hundred and thirty-nine adults received RL-LDLTs with duct-to-duct biliary anastomosis between January 2000 and May 2008 at Kangnam St. Mary's Hospital. Endoscopic retrograde cholangiography (ERC) was performed in 113 patients who had biliary stricture after LDLT. We evaluated the incidence of post-LDLT biliary stricture and the long-term outcome of endoscopic treatment for biliary stricture. The factors related to the outcome were analyzed. RESULTS: Biliary strictures developed in 121 (35.7%) patients, 95 (78.5%) of them within 1 year of surgery. The mean number of ERCs performed per patient was 3.2 (range, 1 to 11). The serum biochemical markers decreased significantly after ERC (p<0.001). Stent insertion or stricture dilatation during ERC was successful in 90 (79.6%) patients. After a median follow-up period of 33 months from the first successful treatment with ERC, 48 (42.5%) patients achieved treatment success and 12 (10.6%) patients remained under treatment. The factors related to the outcome of endoscopic treatment were nonanastomotic stricture and stenosis of the hepatic artery (p=0.016). CONCLUSIONS: Endoscopic treatment is efficacious and has an acceptable long-term outcome in the management of biliary strictures related to RL-LDLT with duct-to-duct biliary anastomosis. Nonanastomotic stricture and stenosis of the hepatic artery are correlated with a worse outcome of endoscopic treatment.
