The Korean Dementia Association (KDA) has been organizing biennial international academic conferences since 2019, with the International Conference of the KDA (IC-KDA) 2023 held in Busan under the theme ‘Beyond Boundaries: Advancing Global Dementia Solutions.’ The conference comprised 6 scientific sessions, 3 plenary lectures, and 4luncheon symposiums, drawing 804 participants from 35 countries. Notably, a Korea– Taiwan Joint Symposium addressed insights into Alzheimer’s disease (AD). Plenary lectures by renowned scholars explored topics such as microbiome-related AD pathogenesis, social cognition in neurodegenerative diseases, and genetic frontotemporal dementia (FTD). On the first day, specific presentations covered subjects like the gut–brain axis and neuroinflammation in dementia, blood-based biomarkers in AD, and updates in AD therapeutics. The second day’s presentations addressed recent issues in clinical neuropsychology, FTD cohort studies, and the pathogenesis of non-AD dementia. The Academic Committee of the KDA compiles lecture summaries to provide comprehensive understanding of the advanced dementia knowledge presented at IC-KDA 2023.

Objectives: This study analyzed the current state of community mental health programs in Korea to develop evidence-based criteria for these programs. Methods: Seventy community mental health facilities nationwide were surveyed about the scope of their operated mental health programs. Details, including program structure, staff expertise, standardization, and quality management, of the 511 programs submitted by the facilities as their representative programs were also analyzed to evaluate their efforts for evidence-based practice. Results: The average number of programs operated by community mental health welfare centers was 15.9. The most common programs were those related to serious mental illness (SMI), followed by child/adolescent mental health programs, early psychosis programs, and non-SMI adult mental health programs. In the case of community addiction management centers, there were 7.2 different addiction-related programs per center. Among the psychiatric rehabilitation facilities for SMI, the average number of programs for SMI was 13.1, with some programs for early psychosis. Of the 511 programs submitted as representative programs in their facilities, only 12.3% were judged to be good evidence-based programs. Conclusion More efforts by mental health professionals and governments are needed to implement evidence-based programs in Korea.

This retrospective case series assessed the effectiveness of commercially available oral fecal microbiota transplantation (FMT) for treating chronic enteropathies in eight animals, five dogs, and three cats, between 2020 and 2023 at the Seoul National University Veterinary Medical Teaching Hospital. Chronic enteropathies, often resistant to conventional therapies, present a significant challenge in veterinary medicine. To assess oral capsule FMT’s effectiveness (Doggybiome ® one capsule daily for dogs and Kittybiome ^® one capsule daily for cats) as a universal adjunctive therapy for chronic enteropathies across species not responding to traditional treatments. This retrospective case series applied a uniform evaluation of gastrointestinal symptoms and treatment efficacy, utilizing established scoring systems (Canine Inflammatory Bowel Disease Activity Index [CIBDAI] and Canine Chronic Enteropathy Clinical Activity Index [CCECAI] for dogs, Feline Chronic Enteropathy Activity Index [FCEAI] for cats) before and one month after FMT. This approach ensured consistency in hypothesis testing across the study population. Results revealed significant improvements in clinical indices post-FMT, with notable reductions in the CIBDAI, CCECAI, and FCEAI scores (p < 0.05). Additionally, symptoms such as anorexia, lethargy, diarrhea, vomiting, and weight loss showed marked improvement, with normalization of appetite and activity levels observed in most cases. No adverse effects were reported, indicating the safety and tolerability of this treatment. This study highlights the potential of oral capsule FMT as a viable therapeutic option for dogs and cats with chronic enteropathies unresponsive to conventional treatments, providing a new avenue for clinical management. Further research is warranted to expand these findings and explore the microbiome changes associated with FMT in veterinary patients.

Although the prognosis of patients with differentiated thyroid carcinoma (DTC) is generally encouraging, a diagnostic dilemma is posed when an increasing level of serum thyroglobulin (Tg) is noted, without detection of a recurrent tumor using conventional imaging tools such as the iodine-131 whole-body scanning (the [131I] scan) or neck ultrasonography (US). The objective of the present study was to evaluate the diagnostic value of [124I]-PET/CT and [18F]-FDG-PET/CT in terms of accurate detection of both iodine- and non-iodine-avid recurrence, compared with that of conventional imaging such as the [131I] scan or neck ultrasonography (US). Between July 2009 and June 2010, we prospectively studied 19 DTC patients with elevated thyroglobulin levels but who do not show pathological lesions when conventional imaging modalities are used. All involved patients had undergone total thyroidectomy and radioiodine (RI) treatment, and who had been followed-up for a mean of 13 months (range, 6-21 months) after the last RI session. Combined [18F]-FDG-PET/CT and [124I]-PET/CT data were evaluated for detecting recurrent DTC lesions in study patients and compared with those of other radiological and/or cytological investigations. Nine of 19 patients (47.4%) showed pathological [18F]-FDG (5/19, 26.3%) or [124I]-PET (4/19, 21.1%) uptake, and were classed as true-positives. Among such patients, disease management was modified in six (66.7%) and disease was restaged in seven (77.8%). In particular, the use of the described imaging combination optimized planning of surgical resection to deal with locoregional recurrence in 21.1% (4/19) of patients, who were shown to be disease-free during follow-up after surgery. Our results indicate that combination of [18F]-FDG-PET/CT and [124I]-PET/CT affords a valuable diagnostic method that can be used to make therapeutic decisions in patients with DTC who are tumor-free on conventional imaging studies but who have high Tg levels.

PURPOSE: Kawasaki disease(KD) manifests a systemic vasculitis of unknown etiology in young children. Vascular endothelial growth factor(VEGF), vascular cell adhesion molecule-1(VCAM-1) and interleukin-1 beta(IL-1beta) may play important roles in the pathogenesis of KD. Intravenous immunoglobulin(IVIG) and methylprednisolone(MP) are therapeutically effective for KD, however, the precise mechanisms of the two drugs are still unknown. We investigated the therapeutic efficacy of IVIG and/or MP for KD in vitro. METHODS: Human umbilical vein endothelial cells(HUVEC) obtained from umbilical cords of healthy newborns were cultured. After HUVEC were treated with IL-1beta, the effect of IVIG and/or MP on the in vitro activation of HUVEC were assessed by cell proliferation and reverse transcription-polymerase chain reaction-detected expression of mRNA coding for VEGF, VCAM-1, and IL-1beta. RESULTS: IVIG and MP down-regulated the expression of VEGF mRNA induced by IL-1beta(P<0.05, respectively) significantly. The combination of both showed a synergistic effect on the expressions with a dose dependent manner of MP compared to the IVIG or MP alone respectively(P<0.05). IVIG and MP down-regulated the expression of VCAM-1 mRNA induced by IL-1beta(P<0.05, respectively). The combination of both showed a synergistic effect on the expressions with a dose dependent manner of MP(P<0.05). IVIG and MP down-regulated the expression of IL-1beta mRNA induced by IL-1beta(P<0.001, P<0.05, respectively). The combination of both showed a synergistic effect on the expressions with a dose dependent manner of MP(P<0.001). CONCLUSION: These results suggested that IVIG and MP are therapeutically effective for KD in vitro as well as in vivo.

PURPOSE: We investigated the menstrual features of adolescent school girls to know the characteristics of menarche and dysfunctional uterine bleeding in adolescents. METHODS: In March, 2001, 1,434 primary and middle school girls(10-15 years of age) in Ansan City were investigated for the menacheal age and several aspects of menstruation through questionnaire. RESULTS: Mean age of the total subjects were 13.0+/-1.2 years of age, and 68.4% of them experienced menarche. 32.2% experienced menarche after age 12, but 82.9% experienced it after age 13. Mixed type(regular and irregular) menstrual cycle was the most common(35.3%), and changing type(irregular to regular) was 27.6%. In changing type, the mean duration of cycle stabilization was 6.6+/-4.9 months. The most common menstrual cycle was 'within 26-30 days'(31.4%). Abnormal cycles such as 'equal or less than 20 days' and 'equal or more than 41 days' were 17.2% and 2.0%, respectively. The most common menstrual duration was '5-6 days'(44.7%). 7.6% of the subjects experienced short or long menstrual duration. Among the subjects, only 4.0% visited the hospital with menstrual problems. The visiting reasons were 'irregular menstrual cycles'(38.5%), 'dysmenorrhea'(28.2%), 'menorrhagia'(12.8%), and 'hypermenorrhea'(28.2%). CONCLUSION: Most adolescent girls in our study experienced menarche until 13 years of age and some of them got early menarche at the age of 9. Many of them had irregular or unstable menstrual cycles after menarche at any age, but only few of them visited a health care provider. We suggest the careful attention of pediatricians, parents and teachers to the early detection and proper treatment of menstrual problems in adolescent girls.

OBJECTS: We developed the Korean version of Hasegawa Dementia Scale(HDS-K) by translating the revised Hasegawa Dementia Scale(HDS-R) which is known to be a useful brief screening instrument for dementia. MATERIALS AND METHODS: The translation was carried out keeping the basic structure of Revised Hasegawa Dementia Scale(HDS-R). HDS-K, along with MMSE-KC, SBT-K and CDR, were administered to 174 dementia patients and 160 elderly control subjects. Cronbach alpha coefficient, inter-rator reliability, and test-retest reliability of HDS-K were examined. The correlations of MMSE-KC, SBT-K and CDR with HDS-K were also examined to confirm the validity of HDS-K. Cut-off scores for dementia were estimated by Receiver Operator Characteristic(ROC) curve anslyses. By comparing Area Under Curve(AUC), the diagnostic efficiency of HDS-K was compared with those of MMSE-KC and SBT-K. RESULTS: 1) HDS-K was found to have significantly high internal consistency(Cronbach alpha coefficient=0.948, <0.01), inter-rater reliability(Pearson correlation coefficient=0.999, <0.01) and test-retest reliability(Pearson correlation coefficient=0.848, <0.01). 2) All the correlations of HDS-K with MMSE-KC, SBT-K and CDR were significant indicating that HDS-K has good concurrent validity. Its optimal cut-off point for dementia was estimated as 15/16, where the sensitivity and specificity were 0.950 and 0.902, respectively. 3) The ROC curve analysis indicated that the diagnostic efficiency of HDS-K(AUC=0.972) was comparable with MMSE-KC(AUC=0.951) and SBT-K(AUC=0.963). CONCLUSION: We conclude that HDS-K is a reliable, valid, and useful screening instrument for dementia.

PURPOSE: In most cases, myelodysplastic syndrome(MDS) transforms into a more aggressive state or acute myelogenous leukemia; it's prognosis is very poor. It is believed that hematopoietic stem cell transplantation(HSCT) is the only curative treatment of MDS, but available data in children are very sparse. In this report, the short term outcome of HSCT in childhood MDS was analyzed. METHODS: Ten children with MDS(CMMoL 5, RAEB 3, RAEBt 2) underwent HSCT(HLA- matched sibling transplantation 4, HLA-matched unrelated transplantation 4, cord blood transplantation 1, HLA-mismatched familial transplantation 1) between November 1995 and January 2001 at St. Mary's Hospital. Median follow-up duration was 11 months. RESULTS: Engraftment was successful in all cases and 8 patients are alive without disease. Three cases of VOD were observed and improved without complication. Four cases of grade II and 1 case of grade III acute GVHD were observed and well controlled with treatment. Three patients relapsed after transplantation. One patient is alive without disease after cytoreduction with allogenic stem cell rescue and 2 patients died of relapse. CONCLUSION: HSCT is a curative strategy of MDS and the survival rate is relatively higher than that of adults. But there is an obvious need for more studies because of the small number of patients and the short duration of the follow-up.

Malignant melanoma is a very rare disease in children. There is an increased risk for the development of malignant melanoma in patient with giant congenital melanocytic nevus. The manifestations of distant metastases in malignant melanoma commonly indicate a poor prognosis. First line treatment of malignant melanoma is excision, but when associated with giant congenital melanocytic nevus, excision is very difficult due to the site and the size of the lesions. However, malignant melanoma is not sensitive to chemotherapy, but a child is more sensitive than an adult. We report a case of unresectable childhood malignant melanoma associated with a giant congenital melanocytic nevus in a 3 year-old female treated with chemotherapy.

PURPOSE: Risk-taking behaviors are defined as patterns of behavior initiated during adolescence which are responsible for the majority of negative health outcomes occurring during the rest of the life. The study was to explore the relationship between the risk-taking behaviors and their predisposing factors among adolescents. METHODS: The study used a survey design with an anonymous self-report questionnaire administered to 1,076 students from first year of middle school to first year of high school in Ansan City. The questions were constructed from nine risk-taking behaviors of independent variables including smoking, alcohol, drug abuse, adaptation at school, use of computer, sexual behavior, vehicle use, suicide, school violence and eight predisposing factors of school grade, gender, academic ranking, academic achievement of the mother, socioeconomic status, living with both parents, religion of the student and the mother. The data was analysed by the statistical methods of X(2) test and Fisher's exact test. RESULTS: The study revealed that the combination of the independent variables of the risk-taking behaviors to have a close association(P<0.05) with the predisposing factors. CONCLUSION: School grades, socioeconomic status, academic rankings, final educational level of the mother and living with both parents were factors strongly correlating with risky behaviors. The role of the clinician to identify those at risk is fundamental for health maintenance long after adolescence.
