Chronic active Epstein-Barr virus (CAEBV) can induce complications in various organs, including the brain and gastrointestinal tract. A 3-year-old boy was referred to the hospital with a history of fever and seizures for 15 days. A diagnosis of encephalitis based on computed tomography (CT) and magnetic resonance imaging findings and clinical correlation was made. Laboratory tests showed positive serology for Epstein-Barr virus (EBV) and negative for Rotavirus antigen and IgG and IgM antibodies for cytomegalovirus, herpes simplex virus, and varicella zoster virus, respectively. Abdominal CT showed diffuse wall thickening with fluid distension of small bowel loops, lower abdomen wall thickening, and a small amount of ascites. The biopsy demonstrated positive Epstein-Barr encoding region in situ hybridization in cells within the crypts and lamina propria. The patient was managed with steroids and hematopoietic stem cell transplantation (HSCT). This case showed histopathological characteristics of concurrent EBV-associated encephalitis and colitis in CAEBV infection. The three-step strategy of immunosuppressive therapy, chemotherapy, and allogeneic HSCT should be always be considered for prevention of disease progression.

Purpose:
The purpose of this study was to examine the acceptability, availability and sustainability of a pilot prenatal program developed by an interdisciplinary team.
Methods:
Out of 19 multicultural women participated in the 6-session prenatal program, 6 women took part in an exit- focus group interview as a part of formative evaluation. The verbatim transcriptions of semi-structured interview data were analyzed using conventional content analysis.
Results:
In general, the participants expressed high satisfaction with program content, educators and education methods. A hybrid model including health professionals and community health workers and using online and offline education modes was suggested as a way to disseminate the program at a national level. Interventions using aesthetic approaches such as music and an integrated method such as the introduction of available social services in pregnancy and during the postpartum period may play a role as the facilitator of the program participation of multicultural women. These approaches may also help them develop healthy coping skills, problem solving skills and empowerment in multicultural childbearing women who need to adjust to life in a new country simultaneously taking a new role as a mother.
Conclusion
An interdisciplinary prenatal program using a holistic approach contributes to enhancing multicultural women’s empowerment to become a mother in a new country.

Purpose:
We aimed to investigate the relationship between the tri-ponderal mass index (TMI), a new indirect measure of fat mass, and insulin-like growth factor (IGF)-I/IGF binding protein (IGFBP)-3.
Methods:
The study included 1,630 children and adolescents who visited Jeonbuk National University Children's Hospital. Each patient’s medical record was retrospectively reviewed for age, sex, height, weight, body mass index (BMI), TMI, and IGF-1 and IGFBP-3 levels. Study participants were divided by sex and then categorized by age, BMI, and TMI. Finally, the correlations of TMI with IGF-1 level, IGF-1 standard deviation score (SDS), IGFBP-3 level, IGFBP-3 SDS, and IGF-1/IGFBP-3 ratio were investigated.
Results:
All participants were <19 years of age. BMI correlated with IGF-1 and IGFBP-3 levels in both sexes; however, the relationship with TMI differed by sex. TMI correlated with IGF-1 and IGFBP-3 SDS in boys and with IGF-1, IGFBP-3, and IGFBP-3 SDS in girls across all ages. In boys, BMI and TMI significantly correlated with IGF-1, IGF-1 SDS, IGFBP-3, IGFBP-3 SDS, and the IGF-1/IGFBP-3 ratio in the normal-weight group. TMI also correlated with IGF-1, IGFBP-3, and IGFBP-3 SDS in the overweight group. In girls, BMI significantly correlated with IGF-1, IGF-1 SDS, IGFBP-3, IGFBP-3 SDS, and the IGF-1/IGFBP-3 ratio in the normal-weight group and with IGFBP-3 and IGFBP-3 SDS in the overweight group, while TMI correlated with IGF-1, IGF-1 SDS, and the IGF-1/IGFBP-3 ratio in the normal-weight group; with IGF-1, IGFBP-3, and IGFBP-3 SDS in the overweight group; and with IGFBP-3 SDS in the obese group.
Conclusion
TMI may more strongly correlate with IGFBP-3 level than BMI in overweight boys and with IGFBP-3 SDS in overweight and obese girls. The correlation of IGFBP-3 SDS with TMI may be helpful for evaluating weight status in adolescent girls.

Purpose:
The purpose of this study is to determine the effect of group education reflecting unmet needs led by Nurse Practitioners (NPs) on essential knowledge regarding chemotherapy for cancer patients and their families undergoing chemotherapy.
Methods:
Conducted at a tertiary general hospital in Seoul from December 30, 2020, to April 30, 2022, this study, which is based on a one group pre-post design, involved 104 cancer patients and their families. It assessed differences in knowledge regarding chemotherapy and satisfaction levels by means of participation through video-based group education led by NPs. The data were analyzed with SAS version 9.4 using paired t-tests and multiple logistic regression analysis.
Results:
The average score of knowledge regarding chemotherapy increased from 80.0 to 89.8 (p<.001). In multivariable logistic regression analysis, being less than 50 years old (adjusted Odds Ratio [aOR]=13.56, 95% Confidence Interval [CI]: 1.76~10.20) and having a college degree or higher (aOR=3.99, 95% CI: 1.15~13.82) were associated with an increase in knowledge regarding chemotherapy. Satisfaction with participation in the group education program was also reported to be high.
Conclusion
This study aimed to develop and implement a group education program for cancer patients and their families undergoing chemotherapy, assess changes in knowledge levels, and investigate satisfaction with the program. As a result of the study, the average score of patients who received the group education program increased; thus, it is an effective method for improving the degree of knowledge about the daily life of cancer patients and the management of side effects.

Purpose:
Although previous studies have found an association between brain iron levels and brain function, few have explored this relationship in children with autism spectrum disorder (ASD). Thus, we aimed to determine the association between quantitative susceptibility mapping (QSM)-derived magnetic susceptibility values (MSVs) and brain function in children with ASD.
Materials and Methods:
The study included children with ASD who underwent both a brain magnetic resonance imaging with QSM and the Wechsler intelligence scale for children intelligence quotient (IQ) test. Select subcortical brain regions (caudate, putamen, globus pallidus, and thalamus; both right and left) were automatically segmented, and the MSVs were extracted from the QSM. The IQ score parameters (verbal comprehension, working memory, perceptual organization, and processing speed indices, and full-scale IQ) were measured. Correlation analysis was used to assess the association between age and IQ test parameters and between age and MSV. Linear regression analysis was performed to measure the relationship between the MSV and IQ test parameters.
Results:
A total of 23 children with ASD (median age [interquartile range]: 10 [8–14] years; 12 males) were included. Age was not correlated with any of the IQ test parameters (p > 0.05). There was a significant correlation between age and right-thalamus MSV (r = 0.443, p = 0.03); however, no such correlation was found with the MSVs of other regions (p > 0.05). Among the IQ test parameters, the verbal comprehension index significantly correlated with the left-caudate MSV (r = 0.420, p = 0.046) and the perceptual organization index significantly correlated with the right-globus-pallidus MSV (r = 0.414, p = 0.049).
Conclusion
Select subcortical MSVs were associated with IQ test parameters in children with ASD, suggesting that QSM is a potential neurodevelopmental marker.
8.Diabetic ketoacidosis in type 1 diabetes mellitus in children and adolescents
Journal of the Korean Medical Association 2024;67(5):335-341
Diabetic ketoacidosis (DKA) is the leading cause of morbidity and mortality in children with type 1 diabetes mellitus (T1DM). Although T1DM can occur in children and adults, DKA caused by T1DM is more severe in children and adolescents and metabolic changes occur more rapidly. This review discusses clinical factors associated with DKA assessed during diagnosis in children and adolescents with T1DM.Current Concepts: DKA is a severe complication that can occur in children with T1DM because of insulin deficiency, leading to high levels of catabolism with increased gluconeogenesis, glycogenolysis, lipolysis, muscle proteolysis, hyperglycemia, and osmotic diuresis. High levels of counterregulatory hormones that enhance ketogenesis have also been noted. High blood sugar levels, dehydration, and the release of ketone bodies into the circulation cause high occurrence of acidosis. DKA can lead to life-threatening complications, such as cerebral edema, which is more common in children than in adults. Other potential complications include kidney failure, respiratory distress, and cardiovascular collapse. Children with T1DM are at a higher risk of developing DKA, particularly during times of illness or stress, or when insulin doses are missed or insufficient. In addition, undiagnosed T1DM in children can lead to DKA when the body enters a state of severe insulin deficiency.Discussion and Conclusion: The risks should be detected earlier and the pathogenesis of T1DM should be understood and assessed by physicians in children and adolescents during check-ups. Furthermore, efforts to increase public awareness are required to reduce the cognitive delays associated with DKA.

Despite the widespread impact of the severe acute respiratory syndrome coronavirus 2 (coronavirus disease 2019, COVID-19) and vaccination in South Korea, our understanding of kidney diseases following these events remains limited. We aimed to address this gap by investigating the characteristics of glomerular diseases following the COVID-19 infection and vaccination in South Korea. Methods: Data from multiple centers were used to identify de novo glomerulonephritis (GN) cases with suspected onset following COVID-19 infection or vaccination. Retrospective surveys were used to determine the COVID-19–related histories of patients who were initially not implicated. Bayesian structural time series and autoregressive integrated moving average models were used to determine causality. Results: Glomerular diseases occurred shortly after the infection or vaccination. The most prevalent postinfection GN was podocytopathy (42.9%), comprising primary focal segmental glomerulosclerosis and minimal change disease, whereas postvaccination GN mainly included immunoglobulin A nephropathy (IgAN; 57.9%) and Henoch-Schönlein purpura nephritis (HSP; 15.8%). No patient progressed to end-stage kidney disease. Among the patients who were initially not implicated, nine patients with IgAN/HSP were recently vaccinated against COVID-19. The proportion of glomerular diseases changed during the pandemic in South Korea, with an increase in acute interstitial nephritis and a decrease in pauci-immune crescentic GN. Conclusion: This study showed the characteristics of GNs following COVID-19 infection or vaccination in South Korea. Understanding these associations is crucial for developing effective patient management and vaccination strategies. Further investigation is required to fully comprehend COVID-19’s impact on GN.
