The amniotic membrane has some characteristics. First, it does not express the human leukocyte antigens, and therefore immunologic rejection is not a concern. Second, it can be obtained easily and sufficiently. Third, because it has antimicrobial properties, transplantation of the amniotic membrane has fewer risks of post-operative infection. So it is under research for the amniotic membrane transplantation in cases of sterile corneal ulcer, pterygium excision,severe chemical and thermal corneal burns, ocular surface defects, conjunctival surface reconstruction after removal of large conjunctival lesions. We have experienced a good result of amniotic membrane transplantation for the conjunctival defect resulting from conjunctival necrosis, in enucleated eye having undergone scleral graft for scleral necrosis. Therefore, we report this case with a review of the literature.

Suppuaration between the orbital bone and the periorbita produces a subperiosteal abscess. Subperiosteal abscess is a rare condition, which usually developes as a complication of the infection of paranasal sinuses. While the case originated from dentoalveolar infection have been reported. The clinical presentation is eyelid swelling, erythema, proptosis, conjunctival chemosis, ocular motility limitation, decreased visual acuity. Diagnostic methods available for evalulating subperiosteal abscess include sinus X-ray, ultrasound, computed tomography(CT), and bacterial culture of abscess content. Subperiosteal abscess is treated with intravenous antibiotics and surgical drainage. Prompt diagnosis and treatement are necessory ot prevent visual loss, cavernous sinus thrombosis, subdural abscess, even death. The authors experienced a sixty one year old male who complianed of right buccal swelling and tenderness, eyelid swelling, erythema, proptosis, conjunctival chemosis, eyeball motility limitation on right eye. His facial computed tomography disclosed subperiosteal abscess with infratemporal and parapharyngeal inflammation. An intravenous antibiotics injection and surgical drainage improve the symptom and sign, So we present our case with a brief review of the literature related to subperiosteal abscess secondary to dentoalveolar inflammation.

BACKGROUND: This study is aimed at describing the outcomes of the management of the patients, caregivers, and healthcare workers (HCWs) who are exposed to the pandemic influenza (H1N1 2009) virus and at evaluating the adequacy in exposure management and infection control. METHODS: From July 2009 to January 2010, for 7 a month period, we managed patients and healthcare workers without any respiratory protective devices, who came within 1 m distance of H1N1-positive individuals for more than 1 h and performed a 1-week follow-up. RESULTS: The total of 157 cases with exposure to pandemic influenza (H1N1 2009) virus and exposed individuals of 907 were reported. Of the exposed individuals who were under management, 15 were confirmed to be infected with the infection rate being 1.7%. The confirmed individuals did not have a secondary infection after the exposure. Rates of infection of the exposed patients and healthcare workers were 1.8% and 1.6%, respectively, and these figures were not statistically significant. CONCLUSION: The exposure management results at the hospital revealed that the infection had spread by contact with individuals who were positive for the infection. The high incidence of early exposure to the virus warrants the need to ensure the use of protective equipment and the adoption of assertive teaching methods that have long lasting effects.

Transcatheter arterial embolization (TAE) is widely used in the treatment of unresectable hepatocellular carcinoma. Its common complications are right upper quadrant pain, nausea, vomiting, and rare complications include focal pancreatic necrosis, gastric ulcer, renal failure, DIC, biliary tree necrosis and splenic infarction and so on. It has been reported that hepatobronchial fistula could develop as a pleuropulmonary complication of liver abscess. We report a case of hepatobronchial fistula caused by complicating liver abscess in a patient with hepatocellular carcinoma who was treated with TAE.

BACKGROUND/AIMS: Paracentesis is an acceptable therapeutic modality for the symptomatic relief of dyspnea or abdominal fullness due to tense ascites in patients with cirrhosis. Whereas studies about the effects of paracentesis focused on the changes about hemodynamics, electrolytes and renal function in great detail, the effects of paracentesis on the changes about respiratory system have undergone limited investigations which are defined large-volume paracentesis. METHODS: We performed pulmonary function tests with arterial blood gas analysis just before and 24 hr after paracentesis. The paracentesis of average 2,300ml was carried out in ten liver cirrhosis patients with tense ascites who were free from underlying cardiopulmonary impairment. RESULTS: 1. The results of pulmonary function test just before paracentesis were as followings; FVC( functional vital capacity), FEV1(forced expiratory volume in 1 sec), FEF25 75(forced expiratory effort 25% 75%) and TLC(total lung capacity) were decreased as 78%, 79%, 62.3% and 89% of normal control value respectively, whereas RV(residual volume) was not decreased. DLCO(lung diffusion capacity of carbon monoxide)was decreased as 61.6%. 2. The results of pulmona function test 24 hr after paracentesis were as followings,' The symptomatic relief of dyspnea was achieved in all participated ten patients. Among lung volume parameters, FVC and VC were increased significantly(p=0.003, p=0.004). Whereas TLC was increased without statistical significance(p=0.228), and RV and FRC(functional residual capacity) showed no change. FEV1 was increased significantly(p=0.039), but FEF25 75 and the ratio of FEF1/FVC showed no change. DLCO was not increased. PaOy(partial pressure of oxygen in arterial blood) was impr'oved without statistical significance. CONCLUSIONS: These results suggest that the patients of liver cirrhosis with ascites have restrictive ventilatory impairment with additional obstructive ventilatory impairment. After paracentesis, the restrictive ventilatop impairment is improved by the relief of diaphragmatic motion limitation caused by ascites. Also, paracentesis of(not large volume, like 5000ml, but) relatively small volume, of 2000 3000ml can achieve objective improvement of dyspnea due to tense ascites.

BACKGROUND: Implantation of esophageal stents is nowadays considered as the method of choice for the management of esophagorespiratory fistula. However, implantation of conventional plastic prosthesis is inconvenient for the patient and associated with relativelty high mortality and complications. Silicone coated self expandable metal stents have been developed to overcome these limitations of plastic tubes. And then, the efficacy of silicone-coated self expandable metal stents in esophagorespiratory fistulas was investigated. METHODS: Six patients with esophagorespiratory fistulas were treated with silicone-coated self expandable metal stents(Song's esophageal stents). All six patients were unable to swallow food or water before treatment due to aspiration via esophagorespiratory fistula. The stents were inserted under endoscopic and fluoroscopic guidence. Clinical improvement was determined by grading food intake capacity on five-point scale : none, liquid, soft food, solid food, or all food. RESULTS: The stents were successfully inserted in all patients. All stents spontaneously showed sufficient expansion without further endoscopic control. After procedure, all fistulas were sealed and symptoms due to branchial aspiration were disappeared. Dysphagia improved by at least two grades in 5 of the 6 patients(83.3%). One patient died due to massive hemoptysis 11 days after stent placement, which could be regarded as a complication. Retrosternal and epigastric pain were observed in three patients. In the follow-up, tumor overgrowth at the end of the stent was found in one patient, who was retreated with implantation of another stent. CONCLUSION: These results suggest that implantation of silicone-coated self expandable metal stents is a rapid, and effective procedure for the palliative treatment of malignant esophagorespiratory fistulas and other cause of esophagorespiratory fistula.

Although ventricular pacing alone initially had deemed adequate for most clinical situations, some patients did not do well after ventricular pacing was initiated, and developed various symptoms attributed to this mode of pacing. The pacemaker syndrome is complex of clinical signs and symptoms related to the adverse hemodynamic and electrophysiologic consequences of ventricular pacing in the absence of other causes. Neurologic symptoms or those congestive heart failure predominated. We recently experienced a case of pacemaker syndrome in a 44-year-old female who had suffered sick sinus syndrome and was implanted with dual chamber pacing system being programmed to VVI pacing. She complained of chest discomfort, dyspnea, and near-fainting in a day after being programmed to VVI. Blood pressure was decreased to 9/60mmHg. Electrocardiography showed toPwave onT wave, representing retrograde ventriculoatrial conduction. The symptoms and signs were disappeared immediately after the pacing system was programmed to DDD pacing.

Methotrexate (MTX) has been widely used in the treatment of psoriasis and rheumatoid arthritis. But prolonged use of MTX can induce hepatic fibrosis and even cirrhosis. To date, in Korea, there have been very few reports on hepatotoxicity due to MTX, and no report on biopsy-proven chronic active hapatitis. We report one patient who developed chronic acitve hepatitis while taking long-term daily dose of MTX(10mg per day) for psoriasis for a prolonged period.

BACKGROUND: Extended-spectrum cephalosporins and fluoroquinolones are important antimicrobials for treating invasive salmonellosis, and emerging resistance to these antimicrobials is of paramount concern. METHODS: A total of 30 Salmonella spp. clinical isolates recovered in Gyeongsangbuk-do from 2012 to 2013 were characterized using antibiotic resistance profiles and pulsed-field gel electrophoresis (PFGE). RESULTS: A high prevalence of multidrug-resistant isolates, mainly showing an ampicillin, nalidixic acid, chloramphenicol resistance pattern, was observed. Four extended-spectrum beta-lactamase (ESBL)-producing isolates (3 CTX-M-15 isolates and 1 CTX-M-27 isolate) were found. The bla(CTX-M-27) gene was carried by an IncF conjugative plasmid in the S. Infantis isolate. The bla(CTX-M-15) gene were carried by an IncF (2 isolates) or IncHI2 (1 isolate) conjugative plasmid in S. Enteritidis. In addition, a single mutation of GyrA, Ser83Thr (1 isolates), Asp87Tyr (9 isolates), Asp87Gly (4 isolates), and Asp87Leu (3 isolates), was detected in nalidixic acid-resistant Salmonella spp. isolates. XbaI PFGE analysis of all isolates revealed more than 19 different pulsotypes. The most common S. Enteritidis PFGE pattern (SEGX01.003) was associated with a larger number of cases of invasive salmonellosis than all other patterns. CONCLUSION: The information from our study can assist in source attribution, outbreak investigations, and tailoring of interventions to maximize disease prevention.

BACKGROUND: The metabolic syndrome (MS) is a cluster of risk factors of cardiovascular disease. The association between components of the MS and bone mineral density has been researched, but no prior studies have directly evaluated the association with the metabolic syndrome and bone mineral density in Korea. METHODS: We evaluated postmenopausal women who had visited a university hospital from November 2006 to October 2007. Data on their lifestyle, current medical diseases and medications were collected from medical records. Height, body weight, waist circumference and serum lipid profiles were measured. RESULTS: The prevalence of metabolic syndrome was 21.8% in this study. In adjusted analysis including age and other factors, only waist circumference had a close correlation with bone mineral density of femur and lumbar vertebral body (P < 0.05). The bone mineral density of femur and lumbar vertebral body had no correlation with the presence of metabolic syndrome. When stratified by body mass index, corrected bone mineral density revealed no significant correlation with the presence of metabolic syndrome. CONCLUSION: The bone mineral density of postmenopausal women with metabolic syndrome has highly influenced by obesity, especially by abdominal obesity.
