Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency and remains a major cause of mortality for very-low-birth-weight infants (VLBWI) requiring surgery. To date, there have been no large-scale studies evaluating the incidence, associated clinical factors and outcomes of NEC for VLBWI in Korea. The 2,326 VLBWI of a total 2,386 Korean Neonatal Network (KNN) cohort born with a birth weight below 1,500 g between January 2013 to June 2014 were included in this analysis. The overall incidence of NEC (stage > or = 2) among VLBWI in Korea was 6.8%; 149 infants had NEC stage > or = 2 and 2,177 infants did not have NEC. Surgery was performed for 77 (53%) of the infants in the NEC group. NEC was related to lower gestational age (GA) and birth weight (P < 0.001). Multivariate logistic regression analysis demonstrated that NEC was consistently related to hypotension within one week after birth (OR 2.0, 95% CI 1.0-3.9). With respect to outcome, the NEC group had longer times to reach 100 mL/kg/day feeding (P < 0.001), longer TPN duration (P < 0.001) and hospitalization (P = 0.031) and higher PVL (P < 0.001) and mortality rate (P < 0.001). When the medical and surgical NEC groups were compared, GA was significantly lower and PDA was more found in the surgical NEC group. The overall incidence of NEC in Korea is similar to that of other multicenter studies. In addition to GA and birth weight, hypotension within a week of life is significantly related to NEC.

PURPOSE: To report the results of surgical repairing of inferomedial orbital wall fractures accompanied with loss of bony strut by an overlapping method using Resorb X(R) plates (poly(D,L)-lactic acid). METHODS: To repair inferomedial orbital wall fractures with loss of bony strut, we bent the medial aspect of the plate for floor fracture according to the anatomical structure and then inserted the floor implant, which was supported by anterior, posterior and lateral margins of the floor fracture. Then, the medial implant, which was supported by the bent medial edge of the floor implant, was inserted. Postoperatively, we analyzed the outcomes of 21 patients regarding postoperative enophthalmos, limitation of eye movement (LOM) and diplopia. The diagonal lengths of the orbit in the operated side were compared with the non-traumatized side based on the coronal view of the postoperative CT scans to determine the success or failure of the reconstruction. RESULTS: The average postoperative enophthalmic value was 0.5 mm, and no significant differences between the orbital diagonal lengths of the operated and non-operated eyes were observed. The LOM shown in 7 out of 8 patients was completely resolved during the postoperative follow-up period. All patients with diplopia, including one patient who showed partial remission of LOM, experienced complete symptom resolution. No other complications related to the implant were recorded. CONCLUSIONS: Inferomedial orbital wall fractures with the loss of bony strut can be successfully repaired by the overlapping method using Resorb X(R) implants.

The purpose of this study was to evaluate the effects of a sealant resin on enamel demineralization in orthodontic bracket bonding. The forty eight extracted sound bovine teeth were subdivided into four groups and treated with Phase II(R) (Reliance, Itasca, Ill) on the surface. Group 1 was not treated. Group 2 was acid etched with 37% phosphoric acid for 30 seconds. Group 3 was applied with sealant after acid etching. Group 4 was applied with resin paste after acid etching and sealant application. Each group was demineralized in artificial caries solution. Demineralized enamel depth was measured by confocal laser scanning microscopy. The results were as follows: the mean demineralized enamel depth was 47.4 micrometer (Group 1), 61.8 micrometer (Group 2), 13.9 micrometer (Group 3), 8.2 micrometer (Group 4); the demineralized enamel depth was increased in Group 2 than in Group 1 (p < 0.05); the demineralized enamel depth was reduced in Group 3 than in Group1 and Group 2 with statistically significant differences (p < 0.05); and demineralization in Group 4 was very little. The results of the present study indicate that sealant application is useful for reducing enamel demineralization in orthodontic bracket bonding.

Background: The aim of this study is to assess the relationships between familial types and dietary quality measured by the Korean Healthy Eating Index (KHEI) in representative Korean elderly. Methods: We used cross-sectional data from 4,260 Korean elderly, aged over 65 years, who had participated in the 2016-2018 Korea National Health and Nutrition Examination Survey. The 14-item KHEI scores were calculated from the Food Frequency Questionnaire and the Dietary Habit Survey from the Nutrition Survey.Familial type was categorized into three groups of Live alone (LA), Live with a partner with or without other(s) (LP), and Live with other(s) without a partner (LO) based on the Household Interview Survey. Results: LP had better dietary quality than LO for both sexes (both P<0.05). LA (64.5; standard error [SE], 1.0) had worse dietary quality than LP (66.7; SE, 0.6]) in elderly male (P<0.05) while they were not significantly different in elderly female. The percentages of subjects having poor dietary quality (total KHEI score of ≤50) in LA, LP, and LO were 20.6% (SE, 2.7), 7.3% (SE, 0.8), 8.9% (SE, 3.6) in elderly male, and 9.6% (SE, 1.2), 5.7% (SE, 0.8), 12.9% (SE, 1.8) in elderly female, respectively. The multivariate-adjusted odds ratios of having poor dietary quality compared with LP was 2.45 (95% confidence interval [CI], 1.66-3.60) for LA male, and 1.98 (95% CI, 1.19-3.28) for LO female. Conclusions Familial type affects dietary quality in Korean elderly. However, differential associations were shown between elderly male and female.

BACKGROUND: Many people experience varying levels of discomfort when confronted with the prospect of dental treatment. Dental treatment can be a traumatic experience, especially for children and adolescents with dental anxiety. In this age group, dental fear causes a significant problem in dental management and has been related to severe dental caries and dental pain. The Dental Fear Survey ( DFS ) is the most widely used measure of dental fear. This study was undertaken to develop the Korean version of the DFS ( K-DFS ) and test its reliability and validity. METHODS: The K-DFS, which uses projective techniques to measure children's and adolescents' dental fear, was developed. The DFS was translated into Korean and participants were selected via convenience sampling. Reliability and validity were tested using data from a sample of 813 middle school students in Gyeonggi Province, selected from the Self questionnaire survey. The K-DFS was administered twice to 102 adolescents aged 12-15 years. RESULTS: The K-DFS had high internal consistency reliability (99.1%) but low test-retest reliability. CONCLUSIONS: The results indicate that the Korean versions of the DFS have good internal consistency reliabilities and test-retest validities. However, we need to further examine the test-retest reliability of the K-DFS and replicate the current study in different samples covering various age groups.

BACKGROUND: There are few previous studies investigating the relationship of dental fear and anxiety (DFA) with dental pain among children and adolescents. To address this issue, we examined the literature published between November 1873 and May 2015 to evaluate the prevalence of DFA and dental pain among children and adolescents, and their relationships with age and sex. METHODS: We performed a broad search of the PubMed database using 3 combinations of the search terms dental fear, anxiety, and dental pain and prevalence. A large proportion of the identified articles could not be used for the review due to inadequate end points or measures, or because of poor study design. Thirty-two papers of acceptable quality were identified and reviewed. RESULTS: We found that the prevalence of DFA was estimated to be 10%, with a decrease in prevalence with age. It was more frequently seen in girls, and was related to dental pain. CONCLUSIONS: We concluded that dental fear, anxiety, and pain are common, and several psychological factors are associated with their development. In order to better understand these relationships, further clinical evaluations and studies are required.

Abdominal epilepsy is an infrequent syndrome which occurrs with gastrointestinal complaints caused by a seizure activity. It is characterized by paroxysmal onset of abdominal pain without visceral disorders, but comes along with the alteration of awareness during the attack and abnormal electroencephalogram(EEG) findings. Like other epilepsies, this abdominal epilepsy is improved with anticonvulsant medication. We present a 14 year-old boy who had recurrent episodes of abdominal pain for 2 months, accompanied by hyperventilation and alteration of awareness. His interictal EEG findings were normal, but 24 hour EEG monitoring showed multifocal spikes and generalized epileptiform discharges when abdominal pain developed. After the medication with valproate, he became free of symptoms and signs.

OBJECTIVE: To investigate the group differences in contents of subjective memory problem and objective cognitive functions in late life depression and mild cognitive impairment. METHODS: 40 participants were classified into three groups [normal, amnestic mild cognitive impairment (MCI), and depression]. Differences in subjective memory complaints were examined using the Prospective and Retrospective Memory Questionnaire. And the Consortium to Establish a Registry for Alzheimer's Disease-Korean version neuropsychological assessment battery results were used for evaluating objective cognitive functions. Group differences were analyzed ANCOVA analysis. RESULTS: In post-hoc analysis, the questions "Do you fail to recognize a character in a radio or television show from scene to scene?" and "Do you forget something that you told a few minute before?" were significantly able to discriminate between the MCI and normal groups. In post-hoc analysis, late life depression group showed significantly higher score on the question "Do you intend to take something with you, before leaving a room or going out, but minutes later leave it behind, even though it's there in front of you?". CONCLUSION: The result demonstrates the presence of differences in the contents of subjective memory complaints according to groups. Subjectively reported memory complaints in MCI group are related to deficits in learning new information. In late life depression, memory complaints are more related to difficulty in executive functions.

PURPOSE: The purpose of the present study was to evaluate the contributing factors to the lymph node status as well as to define the impact of preoperative concurrent chemoradiotherapy (CCRT) on the number of lymph nodes retrieved in mid-low rectal cancer. MATERIALS AND METHODS: We retrospectively analyzed 277 patients who underwent curative surgical resection for mid-low rectal cancer between 1998 and 2007. Eighty-two patients received long course preoperative CCRT followed by surgery. RESULTS: A mean of 13.12+/-9.28 lymph nodes was retrieved. In a univariate analysis, distance from the anal verge, pT stage, pN stage, lymphovascular invasion, preoperative CCRT had significant influence on the number of lymph nodes retrieved. In a multivariate model, patients in the CCRT group had fewer retrieved lymph nodes than the non-CCRT group (p<0.001). Both univariate and multivariate analyses showed that the ypN0 group had fewer retrieved lymph nodes than the ypN1-2 group (p=0.027) in the CCRT group. CONCLUSION: Preoperative CCRT was an independent risk factor for failure to harvest an appropriate number of lymph nodes, and node-negative patients who received CCRT had fewer lymph nodes harvested.
