Background: and Purpose: This clinical practice guideline provides evidence-based recommendations for treatment of dementia, focusing on cholinesterase inhibitors and N-methyl-D-aspartate (NMDA) receptor antagonists for Alzheimer’s disease (AD) and other types of dementia. Methods: Using the Population, Intervention, Comparison, Outcomes (PICO) framework, we developed key clinical questions and conducted systematic literature reviews. A multidisciplinary panel of experts, organized by the Korean Dementia Association, evaluated randomized controlled trials and observational studies. Recommendations were graded for evidence quality and strength using Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. Results: Three main recommendations are presented: (1) For AD, cholinesterase inhibitors (donepezil, rivastigmine, galantamine) are strongly recommended for improving cognition and daily function based on moderate evidence; (2) Cholinesterase inhibitors are conditionally recommended for vascular dementia and Parkinson’s disease dementia, with a strong recommendation for Lewy body dementia; (3) For moderate to severe AD, NMDA receptor antagonist (memantine) is strongly recommended, demonstrating significant cognitive and functional improvements. Both drug classes showed favorable safety profiles with manageable side effects. Conclusions This guideline offers standardized, evidence-based pharmacologic recommendations for dementia management, with specific guidance on cholinesterase inhibitors and NMDA receptor antagonists. It aims to support clinical decision-making and improve patient outcomes in dementia care. Further updates will address emerging treatments, including amyloid-targeting therapies, to reflect advances in dementia management.

Background: Acute bronchiolitis is a common cause of hospitalization during infancy that carries significant morbidity and mortality rates.Purpose: This study compared the efficacy of different treatment modalities for infants with bronchiolitis in terms of hospital stay and clinical severity scores. Methods: The PubMed database was searched for relevant studies. Eligibility criteria included double-blind randomized controlled trial design, assessment of the effect of treatment on bronchiolitis in infants under 2 years of age, and publication in English from inception through July 31, 2020. The primary efficacy outcome was the length of hospital stay, while the secondary outcome was the clinical severity score. The standardized treatment effect and standard error of the effect size were calculated. Results: We identified 45 randomized controlled trials of 24 pairwise comparisons. These 45 trials included 5,061 participants and investigated 13 types of interventions (12 active, 1 placebo). Inhalation therapy with epinephrine (standard mean difference [SMD], -0.41; 95% confidence interval [CI], -0.8 to -0.03) and hypertonic saline (SMD, -0.29; 95% CI, -0.55 to -0.03) reduced the length of hospital stay compared with normal saline. Hypertonic saline was the most effective at improving the clinical severity score (SMD, -0.52; 95% CI, -0.95 to -0.10). Conclusion Inhalation therapy with epinephrine and hypertonic saline reduced the length of hospital stay and the clinical severity of bronchiolitis among infants under 2 years of age.

The purpose of the current study was to examine the risk factors of young children’s smartphone addiction in a longitudinal study design. Data collected from 313 participants (mean age, 4.5 ± 0.82 years; male, 49.8%) over 4 years for Kids Cohort for Understanding of Internet Addiction Risk Factors in Early Childhood were analyzed in this study. Mixed effect models were used to evaluate the influence of various variables on the repeated measures of smartphone addiction tendency in young children over time. The multi-level analysis showed that parents’ lack of control over children’s smartphone use (t = −4.523; 95% confidence interval [CI], −7.32, −1.72), and parents’ higher smartphone addiction proneness (t = 6.340;95% CI, 0.23, 0.440) predicted higher smartphone addiction tendency in young children.The responsibility of the parents to prevent their children from becoming addicted to smartphones should start in a very early age when they start using the smartphones.

Purpose: To assess the prevalence of food allergy, with a focus on oral allergy syndrome (OAS) in a population of children and to investigate relevant allergen sensitization associated with these adverse reactions. Methods: This study involved 1,660 children (aged 4 to 13 years) experiencing seasonal allergy symptoms, who were enrolled in the 2015 prospective Seongnam Atopy Project (SAP 2015) in a South Korean municipality. Parents completed a structured questionnaire to assess children with OAS, collecting information on the duration, severity, and factors related to symptoms. Skin prick tests (n = 498) and blood sampling (n= 464) were performed to measure allergic sensitizations, total eosinophil counts, and levels both total immunoglobulin E (IgE) and birch-specific IgE. Results: The prevalence of OAS among the children enrolled in this study was 4.4% (95% confidence interval, 3.7%–5.1%). The most common symptom was mouth itching (n= 106, 65.0%), and the primary food allergen associated with symptoms was kiwi (n= 48, 29.5%). Peanut sensitization (14.8% vs. 57.1%, P< 0.001) and sensitization to other nut products (15.6% vs. 47.6%, P= 0.001) were linked to a higher incidence of systemic reactions. Conclusion The prevalence of 4.4% underscores the significant health impact of OAS, especially in children experiencing food allergy-related symptoms. Notably, common allergens, such as kiwi, and the potential for additional systemic reactions associated with this condition highlight the importance of raising awareness.
