Anterior open bite and transverse discrepancy are often accompanied by hyperdivergent skeletal patterns. In addition, degenerative joint disorders and vertical maxillary excess contribute to an unfavorable convex facial profile with a retruded chin. Correction of this complex three-dimensional problem with orthodontic treatment alone is considered challenging owing to anatomical limitations. Moreover, a history of orthodontic treatment with premolar extraction makes retreatment difficult. This case report illustrates the application of a maxillary tissue bone-borne expander and biocreative reverse curve system in a 23-year-old female patient with a severe anterior open bite and transverse discrepancy who underwent orthodontic treatment with four premolar extractions. By setting the treatment target under precise diagnosis and using appropriate appliances, a satisfactory treatment result could be achieved without orthognathic surgery.

0.05). The area under the receiver operating characteristics curve (AUC) was 0.922 [95% confidence interval (CI) 0.89–0.95]. In external validation, the discrimination was good, with an AUC value of 0.833 (95% CI 0.70–0.92) for this model. Nomogram calibration plots indicated good agreement between the predicted and observed outcomes, exhibiting close approximation between the predicted and observed probability.CONCLUSION: We constructed a scoring model for predicting massive transfusion during cesarean section in women with placenta previa. This model may help in determining the need to prepare an appropriate amount of blood products and the optimal timing of blood transfusion.]]>

OBJECTIVE: To describe the clinical outcomes of frozen-thawed embryo transfer (FET) with artificial preparation of the endometrium, using a combination of estrogen (E2) and progesterone (P4) with or without a gonadotropin-releasing hormone agonist (GnRHa), and the modified natural cycle (MNC) with human chorionic gonadotropin (hCG) trigger. METHODS: In this retrospective study, we evaluated 187 patients during 3 years (February 2012–April 2015). The patients were allocated to the following treatment groups: group A, comprising 113 patients (181 cycles) who received GnRHa+E2+P4; group B, comprising 49 patients (88 cycles) who received E2+P4; and group C, comprising 25 patients (42 cycles) who received hCG+P4. The inclusion criteria were regular menstrual cycles (length 24–35 days) and age 21–45 years. RESULTS: The primary outcome of the study — implantation rate (IR) per embryo transferred — was not statistically different among the 3 groups. Similar results were found for the IRs with fetal heartbeat per embryo transferred (68/181 [37.6%] in group A vs. 22/88 [25.0%] in group B vs. 14/42 [33.3%] in group C) and for the live birth rates (LBRs) per embryo transferred (56/181 [30.9%] in group A vs. 18/88 [20.5%] in group B vs. 11/42 [26.2%] in group C). CONCLUSION: Although the pregnancy outcomes were better in the hormone therapy with GnRHa group, hormone therapy FET with GnRHa for pituitary suppression did not result in significantly improved IRs and LBRs when compared with hormone therapy FET without GnRHa or MNC FET.

BACKGROUND/OBJECTIVES: Veggiecation was developed to improve children's vegetable consumption through classroom lecture and cooking activities. In this study, we explored potential determinants of vegetable consumption behavior and intention, and examined the impact of Veggiecation on vegetable consumption behavior, intention and personal factors among Korean children. MATERIALS/METHODS: The 4-week Veggiecation program was implemented for second-graders in South Korea (35 children in the intervention group, 36 in the control group). We identified personal and environmental factors influencing vegetable consumption behavior and intention using multiple regression analyses. Consumption behavior, intention and, personal factors such as preference, attitude, and self-efficacy were compared between the groups before and after the intervention. RESULTS: Children's vegetable consumption behavior was significantly correlated with personal, social-, and physical-environmental factors as well as intention. Among the variables, preference was the most influential factor on intention, and attitude and intention had great influence on the behavior. After the program, children in the intervention group demonstrated significant improvements in vegetable consumption, intention, attitude, preference, and self-efficacy compared with children in the control group. CONCLUSION: Veggiecation, a school-based culinary nutrition education program, improved vegetable consumption and intention, as well as preference, attitude, and self-efficacy, in second-graders. Veggiecation has great potential, as a global program, to increase children's vegetable consumption. This program can be expanded through various channels, such as after-school programs or camps, to provide a positive impact for children.

The aim of this study was to validate a new paper and pencil test battery to diagnose minimal hepatic encephalopathy (MHE) in Korea. A new paper and pencil test battery was composed of number connection test-A (NCT-A), number connection test-B (NCT-B), digit span test (DST), and symbol digit modality test (SDMT). The norm of the new test was based on 315 healthy individuals between the ages of 20 and 70 years old. Another 63 healthy subjects (n = 31) and cirrhosis patients (n = 32) were included as a validation cohort. All participants completed the new paper and pencil test, a critical flicker frequency (CFF) test and computerized cognitive function test (visual continuous performance test [CPT]). The scores on the NCT-A and NCT-B increased but those of DST and SDMT decreased according to age. Twelve of the cirrhotic patients (37.5%) were diagnosed with MHE based on the new paper and pencil test battery. The total score of the paper and pencil test battery showed good positive correlation with the CFF (r = 0.551, P < 0.001) and computerized cognitive function test. Also, this score was lower in patients with MHE compared to those without MHE (P < 0.001). Scores on the CFF (32.0 vs. 28.7 Hz, P = 0.028) and the computer base cognitive test decreased significantly in patients with MHE compared to those without MHE. Test-retest reliability was comparable. In conclusion, the new paper and pencil test battery including NCT-A, NCT-B, DST, and SDMT showed good correlation with neuropsychological tests. This new paper and pencil test battery could help to discriminate patients with impaired cognitive function in cirrhosis (registered at Clinical Research Information Service [CRIS], https://cris.nih.go.kr/cris, KCT0000955).

Necrotic enteritis (NE) caused by Clostridium (C.) perfringens commonly occurs in domestic broiler farms since antibiotic supplementation in poultry feed has been banned. We evaluated the antibacterial activities of medicinal plant extracts against C. perfringens isolates to select alternative compounds for preventing NE. We compared antibacterial activities using two methods and evaluated susceptibilities of the isolates based on minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). Two (Fraxinus rhynchophylla Hance [FRH] and Geranium koreanum Kom. [GKK]) of the 30 plant extracts had potent antibacterial activities against C. perfringens ATCC 13124 in two assays. The MIC values for FRH and GKK against 20 C. perfringens isolates were 128~256 microg/mL and 32~128 microg/mL, respectively. The geometric MIC mean values for the two extracts were 147.2 microg/mL and 68.8 microg/mL, respectively. The MBCs for the two extracts against the same strains were 1,024~2,048 microg/mL and 256~1,024 microg/mL, respectively. The geometric mean MIC and MBC for GKK were about two-fold lower than those of FRH. The modified spot-on-lawn assay may be useful for measuring primary antibacterial potential. FRH and GKK are expected to be used as feed additives to prevent or treat NE in veterinary practice.

Journal of the Korean Dietetic Association 2015;21(4):333-341
This article aimed to investigate problems relating to medical tourism based on a review of medical tourism reports and statistics in the global healthcare industry. To be a leading nation in the global healthcare industry, the needs and culture of many peoples, including Muslims, should be considered. Qualified medical services by JCI certification, including nutrition services, will provide opportunities to participate in the international and Asia medical tourism markets. In this article, the definitions of medical tourism, medical service, Halal and Haram, nutrition service for inbound Muslim patients, and Halal food supply in Korea were examined for medical service improvement. Mutual assistance between the government and private enterprise, sharing of medical service information, and construction of a cooperative network system are needed and should be supported by the government.

PURPOSE: Development of a standardized guideline and assessment tool is necessary. Therefore, the aim is to investigate the current state of enteral feeding management and to develop a basis for a standardized guideline. METHODS: From July 1, 2010 through June 30, 2011, this study was conducted retrospectively for 100 patients who had enteral feeding more than once only in the Intensive Care Unit, after General Surgery at Severance Hospital, Yonsei University College of Medicine, Seoul, Korea. The analysis was based on the following factors; age, diagnosis, name of the operation, period of start and the end of enteral feeding, method of injection, flushing method, residual volumes of the stomach, location and the size of the tube, medication through tubing, and complications related to enteral feeding. RESULTS: The mean age of the patients was 60.5, 65 men and 35 women. There were 30 malignant tumors of the hepatobiliary system and pancreas, 8 gastric and duodenal cancer, 4 colon and rectal cancer, 11 peritonitis, hemoperitoneum, and bowel obstruction, and 47 others. The average period of performing enteral feeding was 11.7 days and the locations of enteral feeding tube were stomach 56%, jejunum 39%, duodenum 3%, and undescribed 2%. The methods of enteral feeding were as follows; continuous feeding 19%, cyclic feeding 75%, intermittent and bolus feeding 3%, respectively. Only 1% of patients were on flushing and 16% on stomach residual. The most common complication of enteral feeding was clogging of the tube (5%). CONCLUSION: Due to the lack of detailed charting related to enteral feeding, we were unable to analyze the statistics on the relevance of complication which was the primary endpoint. As a result, development of a standardized protocol on charting enteral feeding is suggested for optimal enteral nutritional support.

PURPOSE: The aim of this study was to evaluate the effects of premedication with oral atenolol or enalapril, in combination with remifentanil under sevoflurane anesthesia, on intraoperative blood loss by achieving adequate deliberate hypotension (DH) during orthognathic surgery. Furthermore, we investigated the impact thereof on the amount of nitroglycerin (NTG) administered as an adjuvant agent. MATERIALS AND METHODS: Seventy-three patients undergoing orthognathic surgery were randomly allocated into one of three groups: an angiotensin converting enzyme inhibitor group (Group A, n=24) with enalapril 10 mg, a beta blocker group (Group B, n=24) with atenolol 25 mg, or a control group (Group C, n=25) with placebo. All patients were premedicated orally 1 h before the induction of anesthesia. NTG was the only adjuvant agent used to achieve DH when mean arterial blood pressure (MAP) was not controlled, despite the administration of the maximum remifentanil dose (0.3 microg kg-1min-1) with sevoflurane. RESULTS: Seventy-two patients completed the study. Blood loss was significantly reduced in Group A, compared to Group C (adjusted p=0.045). Over the target range of MAP percentage during DH was significantly higher in Group C than in Groups A and B (adjusted p-values=0.007 and 0.006, respectively). The total amount of NTG administered was significantly less in Group A than Group C (adjusted p=0.015). CONCLUSION: Premedication with enalapril (10 mg) combined with remifentanil under sevoflurane anesthesia attenuated blood loss and achieved satisfactory DH during orthognathic surgery. Furthermore, the amount of NTG was reduced during the surgery.

BACKGROUND: The value of endoscopy is more increasing as a tool of the cancer screening, and many studies are now progressed for decreasing the inconvenience of patients who undergo the endoscopy. There are some overseas studies that the video-education before procedures like colonoscopy or coronary angiography increases the satisfaction and decreases the anxiety of the patients. But in Korea, there is lack of studies about the methods of decreasing the anxiety of the patients before procedures especially endoscopy. METHODS: We carried out the survey with 95 patients underwent the endoscopy in the medical health checkup center of National Health Insurance Medical Center during 19 July 2008 to 8 September 2008. The patients who had the medical history of gastrectomy, had pains due to another diseases and had a prescription about psychiatric medicine including hypnotics were excluded. RESULTS: Statistically there are no differences between two groups of the video-education and the paper-education according to age, sex, height, weight, body mass index, numbers of former endoscopy, smoking history and educational standard. The video-education is more effective than the paper-education in decreasing the anxiety index between before and after the education. CONCLUSION: The prior video-education for the patients awaiting endoscopy can decrease the anxiety about procedure. Moreover, it can decrease the suffication of the patients and increase the satisfaction of physicians. If the patients feeling the prior anxiety are educated with the video before undergoing endoscopy, the video-education is very effective to decrease the prior anxiety of the patients.
