PURPOSE: To compare the anterior segment parameters including precorneal tear film thickness (PTFT) using Pentacam(R) (Oculus, Wetzlar, Germany) between normal control and dry eye groups and to examine the relationships between the PTFT and other parameters for dry eye. METHODS: The present study included 23 normal controls (31 eyes) and 25 patients with dry eyes (31 eyes). We compared measurements including PTFT, corneal thickness and astigmatism using Pentacam(R) and analyzed the correlations among the PTFT and fluorescein tear break-up time (FBUT), Schirmer I test (without anesthesia), and ocular surface disease index (OSDI). RESULTS: The mean PTFT in dry eyes (21.1 +/- 2.0 microm) was significantly thinner than in normal eyes (37.6 +/- 2.0 microm; p < 0.01). In the dry eye group, the corneal thickness was thicker than in the normal eye group but there were no clinically significant differences. The dry eye group experienced more frequent and severe corneal astigmatism compared with the normal group. OSDI scores showed a weak negative correlation with objective clinical measures of dry eye (FBUT, Schirmer I test) but was not statistically significant. However, OSDI was statistically significantly negatively correlated with PTFT (r = -0.46, p < 0.01). The PTFT showed a weak positive correlation with FBUT and Schirmer I test without statistical significance. CONCLUSIONS: The mean PTFT using Pentacam(R) in the dry eye group was thinner than in the normal group. Additionally, the PTFT was correlated with subjective symptoms. Therefore, the PTFT measurement using Pentacam(R) could be considered a useful method for diagnosis and treatment of dry eye.

PURPOSE: To compare the corneal higher-order aberrations (HOAs) of normal young subjects using Galilei(TM) G4 (Zeimer, Port, Switzerland) and Pentacam(R) (Oculus Inc., Wetzlar, Germany). METHODS: Corneal HOAs were measured using Galilei(TM) G4 and Pentacam(R) in 41 healthy individuals (41 eyes). Intraclass correlation coefficients (ICCs) were obtained to evaluate the repeatability of the 2 devices. Differences in HOAs between the 2 instruments were analyzed with a paired t-test and correlations evaluated. RESULTS: All ICCs measured using Galilei(TM) G4 and Pentacam(R) showed more than moderate repeatability (>0.81) except trefoil, tetrafoil, 4th and 5th HOAs. When comparing the measurements obtained with Galilei(TM) G4 and Pentacam(R), total HOAs, spherical aberration (SA), secondary astigmatism and 5th total HOAs were statistically significantly different between the 2 device (all p < or = 0.001). In addition, Galilei(TM) G4 and Pentacam(R) showed discrepancy among all corneal HOAs items. Although the total corneal HOAs and the SA were significantly correlated, other HOA measurements generally exhibited a low correlation. CONCLUSIONS: Corneal HOAs obtained by the 2 instruments cannot be used interchangeably due to their differences and discrepancy although corneal HOAs measured using Galilei(TM) G4 and Pentacam(R) showed relatively high repeatability.

3.Analysis of the Difference in Nutrients Intake, Dietary Behaviors and Food Intake Frequency of Single- and Non Single-Person Households: The Korea National Health and Nutrition Examination Survey (KNHANES), 2014–2016
Korean Journal of Community Nutrition 2019;24(1):1-17
OBJECTIVES: This study was performed to compare the dietary life of single- and non single-person households in the Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: A nationally representative sample of 20,421 19-64-year-olds who had 24-hour recall data was taken from the 2014-2016 Korea National Health and Nutrition Examination Survey (KNHANES). Single- and non single-persons were compared for nutrient intake, dietary behaviors, food consumption patterns, nutrition education and confirm nutrition label. RESULTS: The dietary intakes of dietary fiber and iron were lower in single-person households than in non single-person households. The lower the level of education and income, the lower the nutrient intake of single-person households. In the case of those aged 19 to 29, the breakfast skipping rate was higher in single-person households than in non single-person households. The higher the education level, the higher the breakfast skipping rate and the eating out frequency in the single-person households. In the food intake survey, the frequency of healthy food intake in single-person households was much lower than that of non single-person households. The confirmation rate of nutrition labeling was lower in single-person households than in non single-person households. CONCLUSIONS: This study shows that single-person households have poorer health-nutritional behaviors than multi-person households. Therefore, a nutrition education program based on the data of this study needs to be developed for health promotion of single-person households.

Objective:
This study aimed to develop and validate a comprehensive self-report questionnaire to assess emotional and behavioral problems and psychological trauma in maltreated children.
Methods:
The Mental Health Scale for Maltreated Children (MHS-MC) was constructed to encompass five major symptoms (depression, anxiety, inattention/hyperactivity/impulsivity, aggression/defiance, and psychological trauma) prevalent in maltreated children. Critical items and ego-resilience subscale were also devised to increase clinical utility. After informed consent, 205 children (maltreated children, n=157, 76.6%) were recruited nationwide, and they answered a package of self-report measures, including the MHS-MC. Reliability, construct validity, concurrent validity, and criterion-related validity were examined to explore the psychometric properties.
Results:
The reliability was good to excellent. Confirmatory factor analysis yielded a five-factorial solution for the symptom subscales supporting construct validity. In logistic regression, the total scores of the MHS-MC predicted membership in the maltreated group. Criterion-related validity was generally satisfactory in that all subscales of the MHS-MC showed significant correlations with relevant measures in the expected direction.
Conclusion
This is the first attempt to develop a comprehensive psychological scale based on nationwide data collected from maltreated Korean children. We hope that the continued standardization of this scale will contribute to evidence-based clinical and policy decisionmaking for maltreated children.

BACKGROUND: Adenoviruses (Ads) are a worldwide cause of endemic and epidemic respiratory infections, particularly in children, young adults and immunocompromised patients. They are responsible for 5% of the acute respiratory infections in children under the age of 4 years and account for about 10% of all cases of childhood requiring hospitalization in this age group. In this study, we report the characteristics of adenoviruses isolated from children with respiratory illness in Busan, 1999~2000. METHODS: A total of 765 children with acute respiratory illness from ten local clinics were studied. Isolation of Ads was performed by inoculating throat swab from patients into Hep-2 cells. The virus propagation was confirmed by the presence of cytopathic effect and adenoviruis specific PCR. Typing of isolated viruses was determined by sequencing analysis of hexon gene. RESULTS: Ads were isolated from throat swab of 17 (2.2%) out of 765 children. The epidemic of Ads infection was concentrated on winter months (December, January, and February). Seventeen Ad isolates showed four serotypes, with Ad3 being the most frequent strain. The distribution of Ads serotypes were eleven (64.7%) Ad3 strains, three (17.6%) Ad5 strains, two (11.8%) Ad2 srtains, and one (5.9%) Ad1 strain. CONCLUSION: Acute respiratory infections by adenoviruses in children were occurred particularly in winter season in Busan. More extended and systematic surveillance of adenovirus infection among populations is required to elucidate the extent of epidemic and disease burden of adenovirus infection.

Endocervicosis refers to the presence of benign mucinous glands of endocervical type in ectopic site. It is rare and usually detected incidentally by histologic examination. The urinary bladder is the most common site, but peritoneum, small bowel, abdominal scar, outer wall of the cervix, vagina, and lymph nodes have been documented. Because this is the first documented report of endocervicosis arising in the rectus muscle in korea, we report this with a brief review of the concerned literatures.

Type 1 diabetes is on the rise worldwide. Although nutrition education for patients with diabetes has become a routine practice, specifics and impacts of such educations need to be more researched. This study examined the status of nutrition knowledge, dietary attitude, and dietary behavior among children and adolescents with type 1 diabetes (9-19 year-old) and explored factors influencing dietary behaviors related to diabetes by applying the Theory of Planned Behavior. Face-to-face interviews, using a pre-tested structured questionnaire, were conducted with 32 participants (11 boys and 21 girls) with type 1 diabetes followed by a diabetes clinic in a university hospital. This study found that the level of nutrition knowledge related to diabetes was generally low at 4 points out of a possible 10, however, the dietary attitude related to diabetes was found to be generally good at 26 points out of a possible 30. Participants were motivated to follow medical staff recommendations the most; however, their family was also important. Perceived behavioral control was low especially for eating-out and portion control. The dietary behavior related to blood glucose control showed low at 13 points out of a possible 20. Regression analysis showed that perceived behavioral control (p < 0.001) was significantly related to the dietary behavior related to blood glucose control. This rare study with children and adolescents with type 1 diabetes showed that nutrition education should include a component to improve perceived behavioral control through high-risk situation management.

Duplication cysts are rare congenital malformations, that may be detected anywhere along the alimentary tract, and they may communicate with the intestinal tract. Cystic duplication of the cecum is especially rare. About 80% of these cases are detected in the first 2 years of life as a result of an acute intestinal obstruction, which manifests as vomiting, recurrent abdominal pain, recurrent gastrointestinal bleeding and constipation. We report a case of intestinal obstruction secondary to a duplication cyst of the cecum in a neonate. The patient underwent surgery and was diagnosed subsequently, and is presently healthy.

On July 6, 2009, an outbreak of gastroenteritis occurred among middle school students in Incheon. An investigation to identify the source and describe the extent of the outbreak was conducted. A retrospective cohort study among students, teachers, and food handlers exposed to canteen food in the middle school was performed. Using self-administered questionnaires, information was collected concerning on symptoms, days that canteen food was consumed, and food items consumed. Stool samples were collected from 66 patients and 11 food handlers. The catering kitchen was inspected and food samples were taken. Of the 791 people who ate canteen food, 92 cases became ill, representing an attack rate of 11.6%. Thirty-one (40.3%) of the 77 stool specimens were positive for Campylobacter jejuni. Interviews with kitchen staff indicated the likelihood that undercooked chicken was provided. This is the first recognized major C. jejuni outbreak associated with contaminated chicken documented in Korea.
