Behcet's syndrome has been known as multisystemic disease caused by nonspecific immune mediated vasculitis, but it's precise etiology is not yet identified. Among the various systemic manifestations, pericardial effusion is extremely rare, and pericardial tamponade caused by massive pericardial effusion in Behcet'sydrome has not been reported in the literature. We report a case of Behcet's syndrome manifested as SVC syndrome due to SVC and right atrial thrombus with massive pericardial effusion resulting cardiac tamponade with the review of the literature.

OBJECTIVE: Performing high quality cardiopulmonary resuscitation (CPR) is important for improving the survival rate with a good neurological outcome and fewer complications. The retention of accurate CPR knowledge is essential for providing high quality CPR. This study examined the effects of chest compression only CPR training on the retention of correct CPR knowledge. METHODS: In December 2016, an interview survey to target the study population was conducted by trained interviewers, using a structured questionnaire. The respondents' general characteristics, status of CPR education, and knowledge and willingness regarding CPR were investigated. Pearson's chi-square tests and multivariate logistic regression analyses were used to determine which education-related factors affected the correct skill knowledge of performing CPR. RESULTS: Among the respondents, there are 80 persons (17.4%) who answered correctly in the questions regarding the skills of performing CPR. The respondents who had a willingness to perform CPR to family and strangers were 90.2% and 44.9% respectively. Through multivariable analysis, the factors related to correct skill knowledge in performing CPR in the didactic with practice group were people who had undergone CPR training within 2 years (odds ratio [OR], 2.293; 95% confidence interval [CI], 1.311–4.009), and person who had undergone chest compression only CPR training (OR, 2.044; 95% CI, 1.033–4.042). CONCLUSION: Chest compression only type of CPR training and the experience of CPR education within 2 years were associated with accurate skill knowledge of performing CPR.

OBJECTIVE: To evaluate effects of short stretch bandage and electrical stimulation therapy (EST) for the complex regional pain syndrome (CRPS) in hemiplegic patients METHOD: 10 hemiplegic CRPS patients after stroke or traumatic brain injury were included in the study. We established CRPS from clinical symptoms and triphasic bone scan. Short stretch bandage was applied on affected limb and changed every 24 hours for 2 weeks. EST was tried for 10 minutes twice per day. It was applied at finger and wrist flexor muscles. We measured hand volume of pre-and posttreatment using hand volumeter. Also compared pre-and posttreatment pain-free range of motion (ROM) of metacarpophalangeal (MCP) joint and third proximal interphalangeal (PIP) joint circumference. RESULTS: Mean difference of hand volume between the affected and the unaffected prior to treatment was 20.5+/-4.9 ml (7.9+/-2.3%). After treatment, mean volume change was 15.5+/-4.9 ml (5.5+/-1.8%) (p<0.05). Mean change of pain-free ROM was 8.0+/-4.8 degree (10.9+/-7.1%), mean change of PIP joint circumference was 3.1+/-1.4 mm (5.9+/-2.4%) (p<0.05). CONCLUSION: Short stretch bandage and EST complex therapy is effective for the reduction of paralyzed hand edema and pain in hemiplegic CRPS patients. However further control study is required.

OBJECTIVE: There is increasing interest in growth hormone (GH) replacement therapy to improve quality of life (QoL) of elderly with age-related decline in GH level (somatopause). The aim of this study was to evaluate the effect of GH replacement on the QoL in patients with somatopause. METHOD: A prospective study of 56 adults with somatopause was conducted. They were replaced with a GH over a 6-month period. QoL was assessed by using three self-rating questionnaires: the Nottingham Health Profile (NHP), the Psychological General Well-Being Index (PGWBI) and theAssessment of Growth Hormone Deficiency in Adults (AGHDA). RESULTS: Significant impairment in QoL as measured by NHP, PGWBI and AGHDA were noted in patients with somatopause compared with age and sex matched normal population (p<0.05). There was significant improvement in QoL after 6-month of GH replacement (p<0.05). CONCLUSION: Six months GH replacement induced an improvement in the QoL of patients with somatopause.

OBJECTIVE: To assess the effect of vitamin K2 in addition to risedronate on postmenopausal osteoporosis METHOD: We enrolled 21 postmenopausal osteoporosis women (age: 65.2+/-7.8 years). Ten subjects received risedronate (35 mg, weekly) and vitamin K2 (45 mg, daily) and eleven subjects only received risedronate. They all received calcium citrate 2,130 mg and vitamin D 600 IU daily. The duration of treatment was 7.7+/-1.4 months. Bone mineral density (BMD) of lumbar spine and both femurs, serum osteocalcin and urine deoxypyridinoline were examined at baseline and after treatment. RESULTS: After treatment, BMD, serum osteocalcin and urine deoxypyridinoline were improved in each group but there was no statistical difference between the groups. CONCLUSION: There was no evidence of the benefit of vitamin K2 in addition to risedronate in bone metabolism on postmenopausal osteoporosis.

PURPOSE: To present and evaluate a system of high-frequency oscillatory ventilator (HFOV) during intra-/inter-hospital neonate transport. METHODS: The system includes a charged HFOV (SOPHIE, Fritz Stephan GmbH, Dusseldorf, Germany), an incubator, and E-oxygen/air-cylinders with connections to the HFOV. The test lung was evaluated at the high and medium ventilator settings used for infants to determine the operating time of HFOV. The time required to exhaust the gas supply was checked, and the HFOV was operated until the low-battery alarm sounded to determine the operating time of the batteries. RESULTS: The batteries provided electrical power for at least 60 mins, and the oxygen and air-cylinders lasted at least 20 mins. The system has been used frequently for the intra-hospital transport, from delivery rooms to ICU and from ICU for surgery. The system has been used twice for the inter-hospital transport of infants with bronchopulmonary dysplasia and pulmonary hypertension to another hospital 45 km away (one hour distance). In one case, the ambulance's electrical power supply failed, causing the system failure during the last 5 mins of transport. However, with the complete check and simulation of the system and the ambulance bulk oxygen/electric supply, the second patient was transported successfully in stable condition. CONCLUSION: The system was useful for intra-/inter-hospital transport of the neonates on HFOV. For the transport time of 60 mins, fully charged HFOV, 2 E-oxygen-cylinders, and 3 E-air-cylinders seemed to be sufficient. H-oxygen-cylinder and ambulance electrical power supply should also be provided for safe and efficient transport between hospitals.

PURPOSE: Children with esophagitis express a variety of nonspecific symptoms and signs depending on their age, and diagnosis is limited because gastrointestinal endoscopy (GFS) and biopsy are difficult to perform. The aim of this study was to examine the prevalence of esophagitis in children with upper abdominal pain, to determine the necessity of esophageal biopsy, and to evaluate the associated risk factors. METHODS: We reviewed 266 pediatric patients with upper abdominal pain who underwent history-taking, physical examination, and GFS with esophageal and gastric biopsies between January 2006 and December 2007. Esophagitis was confirmed on biopsy. We analyzed the risk factors for histologic esophagitis and the necessity of esophageal biopsy. RESULTS: The prevalence of esophagitis was 19.9% (53/266 patients). The sensitivity and specificity of endoscopic diagnosis were 41.5% and 77%. Of 53 patients with histologic esophagitis, reflux esophagitis was seen in 50 patients, eosinophilic esophagitis was seen in 2 patients, and esophageal candidiasis was seen in 1 patient. Vomiting was a significant factor in patients under 8 yr of age (p<0.05). H. pylori infection was documented in 41.5% of patients with histologic esophagitis, compared with 58.5% of patients not infected with H. pylori (p<0.05). The possibility of histologic esophagitis was higher in patients with H. pylori infection (OR 2.5, 95% CI 1.2544 to 4.8286) and in those who visited in the spring (OR 2.5, 95% CI 1.2544 to 4.8286). CONCLUSION: We believe esophageal tissue biopsy should be performed in pediatric patients with upper gastrointestinal symptoms who are undergoing GFS and stomach tissue biopsy, especially preschoolers and H. pylori-infected children in the spring.

Though the pathogenic significance and the reservoir of Ewingella americana have not been clarified, this organism has caused several pathogenic infections, especially in immunocompromised patients. We report a pneumonia in a patient with chronic renal failure, who had chronic rejection of transplanted kidney. E. americana was identified to be the pathogen of pneumonia with clinical symptoms and signs and radiological examination. As soon as he was treated with ceftriaxone and isepamicin, clinical improvement was followed with no further growth of E. americana or other pathogenic isolates from sputum culture. This suggests to be the case of pneumonia caused by E. americana for the first time in the Korean literature.

The fMRI signals are composed of many various signals. It is very difficult to find the accurate parameter for the model of fMRI signal containing only neural activity, though we may estimating the signal patterns by the modeling of several signal components. Besides the nose by the physiologic motion, the motion of object and noise of MR instruments make it more difficult to analyze signals of fMRI. Therefore, it is not easy to select an accurate reference data that can accurately reflect neural activity, and the method of an analysis of various signal patterns containing the information of neural activity is an issue of the post-processing methods for fMRI. In the present study, fMRI data was analyzed with the Independent Component Analysis(ICA) method that doesn't need a priori-knowledge or reference data. ICA can be more effective over the analytic method using cross-correlation analysis and can separate the signal patterns of the signals with delayed response or motion related components. The Principal Component Analysis (PCA) threshold, wavelet spatial filtering and analysis of a part of whole images can be used for the reduction of the freedom of data before ICA analysis, and these preceding analyses may be useful for a more effective analysis. As a result, ICA method will be effective for the analysis of signal patterns in fMRI and the pre-filtering may be necessary for the reduction of the degree of freedom of the data.

The idiopathic hypereosinophilic syndrome consists of peripheral blood eosinophilia of 1500/mm3 or more without a known cause, plus signs and symptoms of organ eosinophilia. The prognosis of HES without treatment is poor. However, about one third of the patients with this syndrome may respond to corticosteroid thrapy. Morever, the majority of the remainder may have a favorable response to hydroxyurea. We present here a case of hypereosinophilic syndrome without any identifiable causes, involving bone marrow, liver, lungs and cervical lymph node. We tried corticosteroid as a treatment but it showed no response. However the hydroxyurea showed good response.
