RESUMO
PURPOSE: Enterovirus infection in children can manifest various disease and enterovirus have many serotypes. This study was aimed to investigate neurologic manifestations according to serotypes of enterovirus in pediatric inpatients in Incheon. METHODS: We collected the stool samples from the admitted pediatric patients in Inha University Hospital from January 2015 to September 2016. Enterovirus detection and serotypes identification were performed by real-time reverse transcriptase polymerase chain reaction (RT-PCR) and semi-nested RT-PCR. RESULTS: A total of 527 samples were collected during study period and 170 patients (32.2%) were diagnosed with enterovirus infections. Genetic sequences of enteroviruses were identified: echovirus 18 (50, 40.5%), enterovirus 71 (12, 9.6%), coxakievirus A10 (10, 8.0%), echovirus 6 (7, 5.6%). Virus in patient with meningitis were identified: echovirus 18 (15, 75%), coxakievirus B5 (2, 10%), enterovirus 71 (2, 10%), and echovirus 6 (1, 5%). Neurologic manifestations of echovirus 18 are headache (15, 30%), vomiting (17, 34%), meningeal irritation sign (10, 20.0%). And enterovirus 71 have headache (3, 25%), vomiting (3, 25%), meningeal irritation sign (2, 16.0%), seizure (1, 8.3%), neurologic sequelae (1, 8.3%). Echovirus 18 and neurologic manifestation have a statistically significant correlation with other serotypes (r=0.701, P < 0.01) CONCLUSION: Echovirus 18 infection was more prominent in neurological symptoms than in other serotypes. The major serotype of meningitis was echovirus 18 but there was no reported neurologic sequelae. Enterovirus infection has different neurological symptoms, depending on the serotypes.

This study aimed to investigate the medically inclined college students' knowledge, attitude, and compliance on the preventive behaviors of the Middle East respiratory syndrome (MERS). A cross-sectional study was conducted on 251 medically inclined college students in Jeonju Kijeon College from June 8 to 13, 2015, using a scale on the knowledge and attitude toward MERS and a structured questionnaire. The t-test, analysis of variance, and Pearson correlation coefficient were used to analyze the data. The participants consisted of 46.6% college students majoring in dental hygiene, 30.7% in clinical pathology, and 22.7% in emergency rescue, and 69.7% of them had been educated on MERS prevention. This study revealed that students who received MERS prevention training (t=3.457, p=0.001) and female students (t=−2.945, p=0.005) had more knowledge on MERS, while students from the dental hygiene department (F=8.048, p<0.001) and those in their third year (F=3.978, p=0.020) showed a more positive attitude toward MERS. Regarding the correlation between knowledge, attitude, fear of infection and compliance on the preventive behaviors, students were more knowledgeable (r=0.133, p=0.036), presented a more positive attitude (r=0.158, p=0.012) and had more fear of infection (r=0.312, p<0.001), were more likely to comply with the preventive measures. For an effective prevention of MERS, a newly found infectious disease, we suggest that medically inclined college students must improve their knowledge of and have a positive attitude toward MERS infection management at a medical institution in compliance with the MERS infection preventive behaviors. Furthermore, this study shows that an infection management education program should be developed, so that which students could learn about the causes, dissemination routes, and preventive methods of infectious diseases, including the newly discovered ones, prior to their clinical training at a medical institution.

PURPOSE: Enterovirus (EV) infection in children can manifest various diseases from asymptomatic infection to nonspecific febrile illness, hand-foot-mouth disease, and aseptic meningitis. This study was aimed to investigate epidemiology and clinical significance of various genotypes of EV infections in pediatric inpatient. METHODS: We collected the stool samples from the admitted pediatric patients in Inha University Hospital from March 2014 to March 2015. EV detection and genotype identification were performed by real-time RT-PCR and semi-nested RT-PCR. Phylogenetic trees were constructed by neighbor joining method. RESULTS: A total of 400 samples were collected during study period and 112 patients (28%) were diagnosed with EV infections. The mean age of EV positive patients was 2.66 years (0.1-14) and sex ratio was 1.73:1. Genetic sequences of EVs were identified; coxsackievirus B5 (17, 15.2%), coxsackievirus A16 (13, 11.6%), enterovirus 71 (10, 8.9%), and coxsackievirus A2 (9, 8.0%). Nonspecific febrile illness (96, 86%) was the most common clinical manifestation and the duration of fever was 0-11 days (mean 3.1 days). Rash (44, 39%) and meningitis (43, 38%) were followed. Patients who were attending daycare center or had siblings accounted for 82.1%. Phylogenetic relationship tree revealed 6 distinct genogroups among 56 types of EVs. CONCLUSIONS: This study is the report of epidemiology, serotype distribution and clinical manifestations of children with EV infection in Incheon. This data will be helpful for further study about the epidemiology of EV infection in Korea.

The incidence of type 2 diabetes is rising rapidly because of an increase in the incidence of being overweight and obesity. Identification of genetic determinants for complex diseases, such as type 2 diabetes, may provide insight into disease pathogenesis. The aim of the study was to investigate the shared genetic factors that predispose individuals to being overweight and developing type 2 diabetes. We conducted genome-wide linkage analyses for type 2 diabetes in 386 affected individuals (269 sibpairs) from 171 Korean families and association analyses with single-nucleotide polymorphisms of candidate genes within linkage regions to identify genetic variants that predispose individuals to being overweight and developing type 2 diabetes. Through fine-mapping analysis of chromosome 4q34-35, we detected a locus potentially linked (nonparametric linkage 2.81, logarithm of odds 2.27, P=6 x 10-4) to type 2 diabetes in overweight or obese individuals (body mass index, BMI> or =23 kg m-2). Multiple regression analysis with type 2 diabetes-related phenotypes revealed a significant association (false discovery rate (FDR) P=0.006 for rs13144140; FDR P=0.002 for rs6830266) between GPM6A (rs13144140) and BMI and waist-hip ratio, and between NEIL3 (rs6830266) and insulin level from 1314 normal individuals. Our systematic search of genome-wide linkage and association studies, demonstrate that a linkage peak for type 2 diabetes on chromosome 4q34-35 contains two type 2 diabetes-related genes, GPM6A and NEIL3.

OBJECTIVE: In this study, we aimed to examine the relationship between chin deviation and the positional and morphological features of the mandible and to determine the factors that contributed to chin deviation in individuals with a unilateral cleft lip and palate (UCLP). METHODS: Cone-beam computed tomography (CBCT) images of 28 adults with UCLP were analyzed in this study. Segmented three-dimensional temporomandibular fossa and mandible images were reconstructed, and angular, linear, and volumetric parameters were measured. RESULTS: For all 28 individuals, the chin was found to deviate to the cleft side by 1.59 mm. Moreover, among these 28 individuals, only 7 showed distinct (more than 4 mm) chin deviation, which was toward the cleft side. Compared to the non-cleft side, the mandibular body length, frontal ramal inclination, and vertical position of the condyle were lower and inclination of the temporomandibular fossa was steeper on the cleft side. Furthermore, the differences in inclination of the temporomandibular fossa, mandibular body length, ramus length, and condylar volume ratio (non-deviated/deviated) were positively correlated with chin deviation. CONCLUSIONS: UCLP individuals show mild chin deviation to the cleft side. Statistical differences were noted in the parameters that represented positional and morphological asymmetries of the mandible and temporomandibular fossa; however, these differences were too small to indicate clinical significance.

BACKGROUNDS: Gestational diabetes mellitus (GDM) is defined as glucose intolerance with onset or first detection during pregnancy and mostly caused by insulin resistance and beta-cell dysfunction like type 2 diabetes. However, autoimmune or monogenic diabetes can contribute to GDM. Maturity-onset diabetes of the young (MODY) is a monogenic form of diabetes characterized by an early age of onset and an autosomal dominant pattern of inheritance. Most MODY cases are attributable to mutations in HNF-1alpha gene, also known as MODY3. We investigated whether mutations in HNF-1alpha gene are present in Korean women with GDM. METHODS: A total of 96 Korean women with GDM who have a family history of DM were screened for mutations in the HNF-1alpha gene. We evaluated the clinical characteristics of GDM women with HNF-1alpha gene mutations. RESULTS: Five of 96 patients (5.2%) were found to have a mutation in HNF-1alpha gene. Four of those (-23C > G, 833G > A (Arg278Gln), 923C > T, IVS5 + 106A > G) were novel and one (-124G > C) in promoter region was reported in previous study. The mean age of GDM women with mutations of HNF-1alpha gene was 34 years. Four women with MODY3 gene mutations required insulin therapy during pregnancy. GDM women with MODY3 gene mutations appeared to be decreased insulin secretion (HOMA-%B) than those without mutations. CONCLUSIONS: We have found the existence of MODY3 as well as novel HNF-1alpha gene mutations in Korean women with GDM.

The regulators of the G protein signaling (RGS) proteins are responsible for the rapid acceleration of the GTPase-activity intrinsic to the heterotrimeric G protein alpha subunits. As GTPase-activating proteins (GAP), the RGS proteins negatively regulate the G-protein signals. Recently, the RGS proteins are known to be one of the important regulators of opioid signal transduction and the development of tolerance. The aim of this study was to review the recent discovery and understanding of the role of RGS proteins in opioid signaling and the development of tolerance. This information will be useful for medical personnel, particularly those involved in anesthesia and pain medicine, by helping them improve the effective use of opioids and develop new drugs that can prevent opioid tolerance.
