PURPOSE: Metabolic Syndrome (MetS) is defined as a cluster of inter-connected metabolic disorders involving the glucose metabolism, dyslipidaemia, high blood pressure, and abdominal obesity. The worldwide prevalence has been rapidly increasing to approximately 20~25%, and the prevalence in Korea as of 2012 was reported to be 31.3%. The association of MetS with various diseases needs to be analyzed by conducting an investigation of frequently consumed foods, such as dairy products, fish, and shellfish in prediabetic subjects. METHODS: The dietary intake of subjects who met the criteria of the study from January to December 2015 was assessed using the 24-hour recall method. After adjusting the age, sex, BMI, and total energy intake, which are confounding factors that may affect the dietary intake of the subjects, the associations of dairy products, fish, and shellfish intake with the MetS risk factors was analyzed. RESULTS: In prediabetes, the intake of subjects who consumed more than the dairy products median (187.0 g) and the elevation risk of TC [OR, 2.369; 95% CI, 1.057 to 5.312] showed a significant positive association. In prediabetes, the intake of subjects who consumed more than the fish and shellfish median (44.0 g) and the elevation risk of BP showed a significantly weak negative association [OR, 0.073; 95% CI, 0.010 to 0.520]. The probability that the blood LDL cholesterol was ≥ 100 mg/dL decreased 0.397 times [95% CI, 0.189 to 0.832]. CONCLUSION: To control the metabolic risk factors of pre-diabetic and vascular disease subjects, proper dairy, fish and shellfish intake will be important.

BACKGROUND: High-frequency jet ventilaion is considered a reliable technique for anesthesia and critical care including respiratory failure but there are adverse reactions such as carbon dioxide retension and dry of respiratory mucosa. The purpose of this study was to confirm the effects of combined high- frequency jet ventilation (HFJV) and converntional mechanical ventilation (CMV) on the cardiovascular system, arterial blood gases tension and mean airway pressure in 9 Korea mongrel dogs with pulmonary edema induced by oleic acid. METHODS: During CMV with 20 breaths/minute, 10 ml/kg of tidal volume and F1O2 1.0, parameers were evaluated (base line value). When pulmonary edema was developed, HFJV was applied initially with 120 breaths/minute, inspiratory time 30% and driving pressure 40 psi F1O2 1.0 for 60 minutes (control value) and thereafter simultaneous use of CMV was applied with the tidal volume of 10 ml/kg and each respiratory rate 8, 4, 2, 1, 0.5 per minute for 30 minutes. RESULTS: Combined application of HFJV and CMV (above repiratory rate 1 per minute) achieved the improvement of oxygenation and carbon dioxide elimination, and Paw was decreased without undesirable effects on cardiovascular system in case of the induced pulmonary edema. CONCUSIONS: From above results we recommanded that HFJV combined with CMV may be a useful method of treatment for respiratory failure.

Purpose: To evaluate the clinical course of neovascular age-related macular degeneration (nAMD) that has shown limited response to ranibizumab and aflibercept. Methods: This retrospective study included 14 eyes with nAMD that showed a limited response to initial treatment using ranibizumab and aflibercept. The changes in visual acuity (VA) during the follow-up period and the incidence and timing of VA deterioration to the level of 0.1 or worse were identified. In cases involving bevacizumab treatment, the follow-up duration and the proportion of patients maintaining a VA of 0.2 or better were identified. Results: During the mean 43.3 ± 33.2 months of follow-up, the VA deteriorated significantly from a mean logarithm of minimum angle of resolution (logMAR) of 0.42 ± 0.34 at diagnosis to 0.91 ± 0.68 at the final follow-up (p = 0.021). A logMAR of 0.3 or greater degree of VA deterioration was noted in six eyes (42.9%). Among the 13 eyes exhibiting a VA of 0.2 or better after the initial treatment, a deterioration to a VA of 0.1 or worse was noted in 6 eyes (46.2%) at a mean 29.7 ± 18.3 months. In eight eyes undergoing bevacizumab treatment, four eyes (50.0%) maintained 0.2 or better VA during the 51.4 ± 35.5 months of follow-up. Conclusions The clinical course of patients with limited response to ranibizumab and aflibercept was generally unfavorable. However, a relatively long period was required for the deterioration in VA to reach 0.1 or worse. In addition, 0.2 or better VA was maintained in approximately half of the patients.

Capsule endoscope is self-contained videoendoscopy device that transmit images of the gastrointestinal tract to an external receiver. Capsule endoscopy has become a very important tool for diagnosing of small bowel disorders. Upcoming capsule endoscopy techniques for the investigation of esophageal, stomach, and colon may render it promising technique for these organs as well. This document is intended to provide the principles by which credentialing organizations may create practical guidelines for granting privileges to perform capsule endoscopy. KSGE recommends that the use of capsule endoscopy be limited to practitioners already competent and privileged to perform standard upper and lower endoscopy and who have extensive experience viewing gastrointestinal mucosa. KSGE recommends additional specific training in capsule endoscopy as well as review of the 20 procedures to verify competence. KSGE also admitted formal fellowship training having a familiarity with the hardware and software systems and interpretation of the at least 10 cases under the supervision of professor in capsule endoscopy during GI fellowship.

OBJECTIVES: The purpose of this study was to assess anger of middle school adolescents in an urban community using State-Trait Anger Expression Inventory (STAXI)-Korean and Korean Child Behavior Checklist (K-CBCL), and to determine whether specific anger expression of adolescents is associated with certain psychopathology including depression. METHODS: Data were collected from 395 middle school students and their parents in Incheon city. The students completed the STAXI, Children's Depression Inventory, Korean version of Mood disorder Questionnaire, and Conners-Wells' Adolescent Self-Report Scale (Short Form), and their parents completed the K-CBCL. RESULTS: No significant correlation was observed between aggression subscale K-CBCL and each scale of the STAXI, except anger out (r=0.704). The scores for STAXI total and respective scales were significantly higher for female students than male students. A stepwise logistic regression model was used to explore the possible predictors for depression in adolescents and lower anger control and higher anger suppression were found to be predictors for depression in adolescence. CONCLUSION: There is a possibility of a large discrepancy between anger that the adolescents actually feel and parents' judgment of their children's anger. It must be considered in assessment of adolescent anger and use of further structured interviews is necessary. In addition, it may be useful to consider the anger expression style in adolescents who report depressive symptoms.

BACKGROUND: Antimicrobial resistance (AMR) is an issue not only with regard to public health, but also in terms of economic impact. AMR surveillance has mainly been carried out in general hospitals, and not in nursing hospitals. This study was conducted to investigate the AMR rate for bacterial strains isolated from nursing hospital samples.METHODS: Antimicrobial susceptibility testing (AST) results from a total of 23,518 bacterial isolates recovered from clinical specimens taken in 61 nursing hosals were analyzed. AST was conducted using Vitek 2 with AST cards specific for the bacterial strains.RESULTS: A total of 19,357 Gram-negative and 4,161 Gram-positive bacterial strains were isolated. Pseudomonas aeruginosa (n=6,384) and Escherichia coli (n=5,468) were the most prevalent bacterial species and, among Gram-positive bacteria, Staphylococcus aureus (n=1,565) was common. The AMR rate was high for the following strains: cefotaxime-resistant Klebsiella pneumoniae, 77.4%; cefotaxime-resistant E. coli, 70.6%; imipenem-resistant Acinetobacter baumannii, 90.3%; imipenem-resistant P. aeruginosa, 49.3%; oxacillin-resistant S. aureus, 81.1%, penicillin-resistant Enterococcus faecalis, 44.8%, and vancomycin-resistant Enterococcus faecium, 53.5%. AMR rate change varied by bacterial species and antimicrobial drug.CONCLUSION: AMR rates of major pathogens from nursing hospitals were higher than those from general hospitals with the exception of imipenem-resistant A. baumannii. Continuous monitoring and infection control strategies are needed.

Neurofibromatosis type I is one of the most common neurocutaneous syndrome which is inherited by autosomal dominant manner, characterized by cafe au-lait spots, axillary freckling, Lisch nodules in iris, multiple neurofibromas and bone involvement with pseudoarthrosis, bowing of the long bone. And Moyamoya disease is a specific disease characterized by progressive idiopathic stenosis and eventual occlusion of the large cerebral arteries at the circle of Willis. In response to the stenosis, an abnormal network of small collateral vessels develops, creating the "puff of smoke". Intracranial lesions associated with Neurofibromatosis type I include optic glioma, sphenoid wing dysplasia, "unidentified bright objects" and cerebrovascular lesions such as Moyamoya syndrome and aneurysm. Moyamoya syndrome is an uncommon association of neurofibromatosis type 1 and lung mass has not frequently been found with neurofibromatosis and moyamoya syndrome. We report a case with Neurofibromatosis type I with Moyamoya syndrome and ganglioneuroma in lung with reviewing literatures.

OBJECTIVES: Thalamic structural changes were implicated in the pathophysiology of schizophrenia by some studies. So, we investigated the differences in thalamic volumes between previously untreated patients with first-episode schizophrenia and controls. METHODS: Thalamic volumes of 24 subjects with schizophrenia and 24 controls were measured from their T1-weighted coronal magnetic resonance images using manual tracing. The thalamus was further segmented into regions that roughly reflected individual thalamic nuclei. RESULTS: Comparing to the controls, significantly smaller volumes were found in the left posterior subdivision of thalamus in patient group. Tendency of volume differences were also seen in right posterior subdivision of thalamus in patient group. These regions primarily comprised the pulvinar, a thalamic nucleus thought to be an important component of aberrant circuitry in schizophrenia. CONCLUSION: Our findings suggest the possibility of a volumetric alteration of the thalamus in patients with first-episode schizophrenia.

STATEMENT OF PROBLEM: The use of zirconia prostheses fabricated with CAD/CAM system is on an increasing trend in dentistry. However, evaluation of the fit related to internal relief and marginal reproducibility of zirconia has not been reported. PURPOSE: This study was to evaluate the fit related to internal relief and marginal reproducibility of zirconia core fabricated with CAD/CAM system. Materials and methods: The evaluation was based on 30 zirconia cores and 5 IPS-Empress2 cores. Zirconia cores were fabricated in different conditions of internal relief(0, 10, 20, 30, 40 and 50 micrometer), and IPS-Empress2 cores were fabricated in accordance with the manufacturer's instructions. Before cementation, the marginal discrepancies of cores were measured on metal die. And then, each core was cemented to stone die, embedded in an acrylic resin and sectioned in two planes(mesiodistally and labiopalatally). The internal gaps were measured at the margin and axial surface. Measurements for the marginal discrepancies, the internal marginal gaps and the internal axial gaps were performed under a measuring microscope(Compact measuring microscope STM5; Olympus, Japan) at a magnification of *100. In addition, the marginal configurations of metal die, zirconia core and IPS-Empress2 core were examined with SEM(S-2700, Hitachi, Japan). RESULTS: Within the limits of this study the results were as follows. 1. Compared with IPS-Empress2 cores, the marginal discrepancies of zirconia cores had no significant differences, the internal marginal gaps were statistically smaller and the internal axial gaps were statistically larger in each condition of internal relief. 2. The marginal discrepancies and the internal marginal gaps of zirconia cores had no significant differences related to the conditions of internal relief(P>0.05). 3. The internal axial gaps of zirconia cores with 0.20micrometer for internal relief were significantly larger than that with 50micrometer(P<0.0001). 4. SEM micrographs showed favorable marginal reproducibility of zirconia core and smooth texture on the milling surface. CONCLUSION: The marginal discrepancy and the internal gaps of zirconia core were clinically acceptable and the milling surface was showed smooth texture. For fabrication of the durable esthetic restoration, further investigations on complex design of core, milling accuracy, compatability of enamel porcelain and porcelain firing seems to be needed.

BACKGROUND/OBJECTIVES: The effects of fish consumption by subjects with prediabetes on the metabolic risk factors were examined based on the data from the 6th Korea National Health and Nutrition Examination Surveys in 2015. SUBJECTS/METHODS: A total of 1,520 subjects who agreed to participate in a blood test and dietary intake survey were divided into a prediabetes group and normal blood glucose group, and the level of the subjects' fish consumption was divided into ≤ 17.0 g/day, 18.0–93.0 g/day, and ≥ 94 g/day. The correlation between the level of fish intake and the metabolic risk factors was evaluated by multinomial logistic regression analysis. RESULTS: A significant difference in the gender distribution was observed in the prediabetes group, which is a group with a high risk of non-communicable diseases, according to the fish intake, and there were significant differences in the total energy intake, protein intake, n-3 fatty acids intake, and the intakes of sodium and micro-nutrients according to the intake group (P < 0.05). In addition, the blood total cholesterol (TC) decreased 0.422 fold in model 1 (unadjusted) [95% confidence interval (CI): 0.211–0.845] and 0.422 fold in model 2 (adjusted for sex) (95% CI: 0.210–0.846) in those with a fish intake of 18.0–93.0 g/day (P < 0.05) compared to those with a fish intake of ≤ 17.0 g/day. The blood TC decreased 0.555 fold (95% CI: 0.311–0.989) in model 1 and 0.549 fold (95% CI: 0.302–0.997) in model 2 in those with a fish intake of ≥ 94 g/day compared to those with a fish intake of ≤ 17.0 g/day (P < 0.05). CONCLUSIONS: Subjects with prediabetes or the metabolic risk factors can maintain their blood low density lipoprotein cholesterol (LDL-C) and blood TC concentrations at the optimal level by consuming fish (18.0–93.0 g/day).
