Congenital lingual cyst is rare and there has been no prior case report about prenatally detected lingual cyst in Korea. When a huge oral cyst is observed at prenatal period and can cause life-threatening airway obstruction at birth, ex utero intrapartum treatment (EXIT) procedure is needed to secure the airway. Herein we present a baby with a prenatally detected huge oral cyst. He was delivered safely assisting EXIT procedure and underwent an operation for resection of the cyst from his tongue. The oral cyst was diagnosed as a lingual cyst with rare histologic type consisting mixed gastrointestinal and respiratory epithelium.

The purpose of this study was to investigate effects of nutrition education program and pamphlet for the lower grades elementary students focused on individual daily needed food exchange units using Food Exchange System. Program consisted of four lessons (40 min/lesson), "5 major nutrients & function", "6 food group and sources", "daily needed food exchange units for normal body weight", and "smart snack choice and exercise". Pamphlet as activity book was developed for the program. The subjects were 3rd grade elementary students (educated group, 31 vs. non-educated group, 31). Educated group were lessoned as group and/or individual. We examined the differences in nutrition knowledge, dietary attitudes, dietary intakes and satisfaction of the program and pamphlet. In educated group, there were positive improvements on nutrition knowledge score "function and foods of 5 nutrients" and on dietary attitudes "type of breakfast and snacks". In the evaluation of dietary intakes according to KDRI, there were positive improvements on intakes level of riboflavin, vit. C, folate, Ca, P, Fe and Zn in educated group. In satisfaction with the program and pamphlet, contents, font size, visual, figure, difficulty and program curriculum were over 2.90/3.0. It showed that the developed nutrition education program and pamphlet focused on individual daily needed food exchange units using Food Exchange System improved nutrition knowledge, dietary attitudes and nutrients intake level in the lower grades elementary students.

BACKGROUND: Obesity is the most common nutritional disorder in Western society as well as in Korea. Obesity results from a combination of genetic, environmental, and behavioral factors. MATERIALS AND METHODS: In an attempt to investigate the association of obesity with its candidate genes, beta3 adrenergic receptor (beta3AR) and uncoupling protein 2 (UCP2), we analyzed polymorphisms of beta3AR Trp64Arg and UCP2 -866G/A by PCR-RFLP analysis and the obesity-related phenotypes, including body mass index (BMI), fasting glucose concentration, and plasma lipid profiles in 750 subjects. RESULTS: The Trp64Arg polymorphism in the beta3AR gene was not statistically associated with the BMI. The UCP2 -866G/A polymorphism was significantly higher in obese than in non-obese subjects (P<0.05). However, the UCP2 -866A/A polymorphism was higher in the non-obese subjects. CONCLUSION: These results suggest that the UCP2 -866G/A polymorphism might be more useful for the prediction of obesity and obesity-associated diseases in Korean patients than the beta3AR Trp64Arg polymorphism.

Cancer metastasis to the skin, especially epidermotropic metastasis, is uncommon. Sometimes it is difficult to find the primary lesion; immunohistochemical (IHC) staining of cutaneous metastasis is used to determine the origin, but diagnosis may occasionally prove difficult. A 77-year-old man visited our hospital with a 1-month diagnostic history of multiple nodules in the right axilla. The patient had undergone surgery for gastric adenocarcinoma (T3N3M0) 21 years ago, and was diagnosed with lung adenocarcinoma 1 year previously; however, no treatment was ongoing. Biopsy of the lesions revealed atypical cells surrounding the papillary projections of the epidermis and tumor nests of the upper dermis. IHC staining was positive for CK7 and CEA and negative for CK5/6, CK20, napsin A, TTF-1, GCDFP 15, and p63. The tissues revealed glandular structures and tested negative for p63 and CK5/6 on IHC staining. The patient was diagnosed with epidermotropic metastasis of lung adenocarcinoma.

BACKGROUND: There is high interest in a new approach to improve children's lifestyle habits in order to prevent childhood obesity. A smartphone application (app) is a new technology platform that can be used to prevent childhood obesity. METHODS: The key messages for healthy eating habits and physical activities were selected by experts in nutrition, physical activity, and psychology and were adjusted for use in elementary school students. Gamification techniques were used to increase app user engagement. A total of 249 students in grades 4-6 were asked to rate their satisfaction for the app after 4 weeks of use. RESULTS: The main menu of "HAPPY ME" was composed of user profile, "EVERYDAY QUEST," exercise diary, diet diary, settings, and notifications. The app users were asked to complete 6-9 daily missions regarding healthy eating habits and physical activities through "EVERYDAY QUEST." The mean satisfaction scores for each variable were distributed from 3.6 to 4.0 points, and most of the students responded that they would continue to use the app (4.0 points). CONCLUSION: We developed a smartphone app (HAPPY ME) for 4th-6th grade elementary students aimed to provide educational information about healthy eating habits and physical activities in order to prevent childhood.

The purpose of this study was to investigate any relationship between the geometric factors of synaptic contacts of muscle spindle afferent terminals and masseteric motor neurons in the trigeminal motor nucleus. Terminals from the masseteric muscle spindle afferents were stained with intra-axonal injection of HRP and were examined electronmi-croscopically with serial sections at the central and peripheral regions of trigeminal motor nucleus of the cat. The number of terminals examined were 76 in peripheral and 105 in central region. The results obtained were as follows. 1. Most of the labeled terminals showed simple synaptic connectivity. Each terminals in peripheral and central region made synaptic contact with 1 to 5 neuronal profiles. Two or three labeled terminals were occasionally seen to make synaptic contact with the same dendrite. 2. The average number of postsynaptic proximal dendrite per labeled terminal was higher in the central region than in the peripheral region. In contrast, that of postsynaptic distal dendrite per labeled terminal was higher in the peripheral region than in the central region. 3. The average diameter of postsynaptic dendrites in the central region was larger than that in the peripheral region. This imply terminals in the peripheral region contacted with further distal part of the distal dendrite than that in the central region. These results indicate that synaptic connectivity associated with the spindle afferents from masseteric muscle is different according to their geometric location within the trigeminal motor nucleus and suggest that there will be precise interrelationship between the morphology, pattern of synaptic connectivity and functions of muscle spindle afferents.

BACKGROUND: Osteoarthritis (OA) is a chronic disease that commonly afflicts the elderly. This disease reduces the health-related quality of life (HRQoL) and causes a significant social burden. Whether the effect of coexisting chronic conditions on HRQoL varies according to the presence of OA remains unclear. Therefore, this study aimed to investigate this notion. METHODS: A total of 13,395 participants were identified from the 2009–2013 Korean National Health and Nutrition Examination Survey for analysis. HRQoL was assessed using the European quality of life-5 dimensions (EQ-5D) index. Patients with OA were defined as those diagnosed by a physician or those who displayed both, symptoms and radiological findings consistent with OA at the time of the survey. Associations between OA and 8 chronic conditions were tested using regression analysis. RESULTS: The EQ-5D index was lower in patients with OA than in those without (mean difference, −0.145; 95% confidence interval [CI], −0.138 to −0.151; P<0.001). Most patients with OA and chronic conditions showed a lower score than those without. EQ-5D was particularly lower in OA patients with hypertension, dyslipidemia, stroke, and renal failure. The estimated β coefficient for the interaction term was significant in renal failure (−0.034; 95% CI, −0.055 to −0.012), after adjusting for demographic and socio-economic variables. CONCLUSION: OA significantly affects HRQoL of Korean elderly individuals alone or when combined with other conditions. OA combined with renal failure is particularly detrimental. These results indicate the importance of managing OA, which is an underestimated disease in public health surveys.

Percutaneous mitral balloon valvuloplasty (PMBV) is the treatment of choice for mitral stenosis. Only a few reported cases have been reported in PMBV patients worldwide. In this study, a case of a 34 year-old female with infective endocarditis a year after PMBV is presented. The patient presented with fever, and peripheral vascular symptoms. Transthoracic echocardiography showed vegetation on the anterior mitral leaflets and Staphylococcus Viridans was isolated from blood cultures. The patient was successfully treated with Amoxicillin + Clavulate and Gentamicin. Further studies on the correlation between PMBV and infective endocarditis are needed.

Hypokalemia causes metabolic alkalosis and morphological changes of the kidney. K⁺ balance is regulated not only by ion channels or pump gene, but also by various genes including NF-E2-related factor 2 (Nrf2). Previous study suggested the possibility that Akt and ERK kinase may be involved in Nrf2 transcriptional gene activation. In present study, we investigate the alterations of Akt, p-Akt, ERK, p-ERK protein in both normal kidney and K⁺-deficient diet kidney using Western blot analysis, and immunohistochemisrty. Our western blot data showed that the expression of Akt and p-Akt was increased gradually in K⁺-depleted diet (from 1W-3W) compared to normal group. The expression of ERK and p-ERK was markedly increased in K⁺-depleted diet 2W in comparison with normal group. Based on our immunostaining results, Akt protein immunoreactivity was prominently increased in outer medullary collecting duct, especially in K⁺-depleted diet 2 weeks. The localization of p-Akt proteins in K⁺-depleted groups was not different from normal group, but the immunoreactivity was significantly increased in distal convoluted tubule, macula densa and outer medullary thick ascending limb in K⁺-depleted diet 1 and 2 weeks groups. ERK protein immunoreactivity was prominently increased in outer medullary collecting duct, especially in K⁺-depleted diet 2 and 3 weeks. The localization of p-ERK proteins in K⁺-depleted groups was not different from normal group, but the immunoreactivity was prominently increased in the nucleus of outer medullary collecting duct especially in K⁺-depleted diet 2 weeks. Taken together, we suggest that the expression of p-Akt was gradually increased in K⁺-depleted groups of kidney, but the expression of p-ERK was markedly increased in K⁺-depleted diet 2 week group. Hence, the promotion of AKT and ERK phosphorylation in hypokalemic condition may be involved in the regulation of ion channels, ion transporters and subsequent intracellular signal transduction.
