This study aimed to evaluate the current oral health status of Korean children and adolescents and investigate the correlation between fasting plasma glucose levels and oral health in individuals with overweight and obesity. A total of 121,682 participants were selected from the Survey of School Health Examination data provided by the Ministry of Education over the last 5 years to assess recent oral health status and related factors. Among them, 18,105 students with overweight or obesity who had their fasting plasma glucose levels measured were assessed for blood glucose-related analysis. Based on fasting blood glucose levels, the participants were categorized into normal, impaired fasting glucose, and diabetes groups. The associations of these groups with dental caries, oral hygiene, and periodontal diseases were investigated. There were significant associations between demographic factors, health-related behaviors, and blood glucose levels with oral health. Increased fasting blood glucose levels were associated with poor oral health. These results suggest that glycemic management is important in enhancing the oral health of overweight and obese children and adolescents.

Facial burns in infant can disrupt maxillofacial growth, leading to deformities and functional impairments. These burns, often occurring in children aged 8–13 months, may result in malocclusion and facial asymmetry caused by altered neuromuscular development. The historical principles of maxillofacial burn management have been established by pioneers such as Kazanjian and Hyslop. In 1849, Simon P. Hullihen performed the first documented orthognathic surgery for a burn-induced deformity on a young patient with mandibular prognathism. In the present study we discuss a similar case involving a 10-year follow-up, demonstrating the use of virtual surgical simulation in evaluating and treating maxillofacial deformities resulting from electrical burns in children.

Objectives: This study identifies factors for differential diagnosis among lesions by retrospectively comparing panoramic and cone-beam computed tomography images and analyzing the characteristics of lesions associated with impacted mandibular third molars (IMTs). Materials and Methods: A retrospective cohort study was conducted in patients who simultaneously underwent IMT extraction surgery and related benign tumor resection or cyst enucleation at our institution from 2017 to 2021. To compare the characteristics of each group, two comparative analyses were conducted. The first comparison considered the most frequently observed lesions associated with IMTs: dentigerous cysts, odontogenic keratocysts (OKCs), and ameloblastoma. The second comparison involved placing dentigerous cysts, which have a relatively low recurrence rate, into group A and placing OKC, ameloblastoma, and odontogenic myxoma, which have high recurrence rates, into group B. Results: Significant differences in the size of the lesion were found in the order of ameloblastoma, OKC, and dentigerous cyst (P<0.05). The buccolingual width of ameloblastoma differed significantly from that of the other groups, with no significant difference observed between the OKCs and dentigerous cysts (P=0.083). Conclusion Patient age and lesion size differed significantly among lesion types associated with IMTs, with younger age and larger lesions for OKCs and odontogenic tumors. OKCs are likely to have a larger mesiodistal width than dentigerous cysts. The buccolingual width of ameloblastomas was larger than those of dentigerous cysts and OKCs.

Kimura disease is characterized by painless subcutaneous masses, usually in the head and neck area as well as serum/tissue eosinophilia and elevated serum IgE levels. Various treatment methods, such as surgical excision, corticosteroids, and radiotherapy, have been suggested, but none of these are considered standard therapy due to high recurrence rates. Dupilumab is a human monoclonal antibody that binds to the alpha subunit of IL-4 receptor for IL-4 and IL-13 and inhibits T helper 2 (Th2) response, which plays an important role in the pathogenesis of allergic diseases, such as atopic dermatitis, asthma, and nasal polyps. Kimura disease has also been shown to increase CD4+Th2 cells and Th2 cytokines. We report a case of a 12-year-old boy who had subcutaneous neck and orbital masses of Kimura disease concurrent with allergic rhinitis, decreased lung function, and IgG subclass deficiency. The masses did not improve with omalizumab or immunomodulatory agents, but resolved with dupilumab. Considering potential side effects of steroids or immunosuppressant agents, dupilumab may be an option for initial treatment with Kimura diseases in children.

Background: Most epidemiological studies depend on the subjects' response to asthma symptom questionnaires. Questionnaire-based study for childhood asthma prevalence may overestimate the true prevalence. The aim of this study was to investigate the prevalence of “Current asthma” using the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire and methacholine challenge test in Korean children. Methods: Our survey on allergic disease included 4,791 children (age 7–12 years) from 2010 to 2014 in Korean elementary schools. Bronchial hyperresponsiveness (BHR) was defined as provocative concentration of methacholine causing a 20% fall in forced expiratory volume in one second (FEV1) (PC20) ≤ 16 mg/mL. “Current asthma symptoms” was defined as positive response to “Wheezing, current,” “Treatment, current,” or “Exercise, current.” “Current asthma” was defined when the subjects with “Current asthma symptoms” showed BHR on the methacholine challenge test or had less than 70% of predicted FEV1 value. Results: The prevalence of “Wheezing, ever,” “Wheezing, current,” “Diagnosis, ever,” “Treatment, current,” “Exercise, current,” and “Current asthma symptoms” was 19.6%, 6.9%, 10.0%, 3.3%, 3.5%, and 9.6%, respectively, in our cross-sectional study of Korean elementary school students. The prevalence of BHR in elementary school students was 14.5%. The prevalence of BHR in children with “Wheezing, ever,” “Wheezing, current,” “Diagnosis, ever,” “Treatment, current,” and “Exercise, current” was 22.3%, 30.5%, 22.4%, 28.8%, and 29.9%, respectively. BHR was 26.1% in those with “Current asthma symptoms.”The prevalence of “Current asthma” was 2.7%. Conclusions Our large-scale study provides 2.7% prevalence of current asthma in Korean elementary school children. Since approximately one third of the children who have “Current asthma symptoms” present BHR, both subjective and objective methods are required to accurately predict asthma in subjects with asthma symptoms.

BACKGROUND/AIMS: Bleeding is one of the major complications of a colorectal polypectomy. The aim of this study was to identify the risk of delayed bleeding, particularly after a colorectal endoscopic mucosal resection (EMR) without prophylactic clipping.METHODS: Between April 2014 and August 2014, patients who underwent colorectal EMR (≥6 mm and < 2 cm) without prophylactic clipping were included. This study evaluated the incidence of delayed bleeding and the associated factors after colorectal EMR without prophylactic clipping.RESULTS: A total of 717 colorectal polyps (≥6 mm and < 2 cm) of 243 patients resected by colorectal EMR in the study period were evaluated. The mean age of the patients was 63 years; 165 patients were men and 78 patients were women. The mean polyp size removed by colorectal EMR was 9.0 mm (range 6.0–19.0), and the number of polyps larger than 1 cm was 212 (29.6%). Delayed bleeding after colorectal EMR occurred in 12 polyps (1.7%) in eight patients (3.3%), and there were no significant risk factors affecting delayed bleeding.CONCLUSIONS: This study identified that the incidence of delayed bleeding on colorectal polyps (≥6 mm and < 2 cm) after EMR without prophylactic clipping was 3.3%, but no significant risk factors affecting delayed bleeding were found.

OBJECTIVE: This study investigated peripheral and central metabolites affecting depression, anxiety, suicidal ideation, and anger in complex regional pain syndrome (CRPS) patients. METHODS: Metabolite levels were determined in the right and left thalamus and insula, in 12 CRPS patients using magnetic resonance spectroscopy (MRS). RESULTS: There were positive correlations between valine (Val)/tNAA (N-acetylaspartate+N-acetylaspartylglutamate) and the anxiety, and a negative correlation between glutamine (Gln)/NAA and the depression. There were positive correlations between alanine (Ala)/Gln and the depression and suicidal ideation, between glutamate (Glu)/Gln and the depression and suicidal ideation, between N-acetylaspartylglutamate (NAAG)/Gln and the depression. There was a positive correlation between Ala/NAAG and the trait anger and a negative correlation between creatine (Cr)/N-acetylaspartate (NAA) and the trait anger. There was a negative correlation between Cr/Glx (Glu+Gln) and the trait anger. High hemoglobin and alkaline phosphatase were associated with low pain levels, but CO2 and chloride showed positive correlations with pain levels in CRPS patients. Peripheral glucose, CO2 and chloride were associated with depression, anxiety, anger and suicidal ideation. CONCLUSION: The specific central and peripheral metabolites were associated with psychological disorders including depression, anxiety, suicidal ideation and anger in CRPS patients, showing pathological interactions between a painful body and mind.
