This comprehensive review examines the crucial role of micronutrients in the health of children and adolescents, focusing on their growth and development. Micronutrients, including vitamins and trace elements, are essential for various biochemical processes and biological functions. We explored the roles, assessment methods, deficiency patterns, and intervention strategies for six essential micronutrients: iron, zinc, vitamin A, vitamin D, iodine, and folate. These nutrients were selected based on their fundamental importance in pediatric development. By analyzing the current literature from PubMed, Embase, and Web of Science databases, we synthesized findings regarding the impact of these micronutrients on health outcomes in children and adolescents, examining both regional and global prevalence data, with particular attention paid to Korean population data. This review provides evidence-based insights into the assessment and management of micronutrient status in children and adolescents and offers recommendations for clinical practice.

Abstract PDF

The prevalence of childhood and adolescent obesity has increased and exacerbated during the coronavirus disease 2019 pandemic, both in Korea and globally. Childhood and adolescent obesity poses significant risks for premature morbidity and mortality. The development of serious comorbidities depends not only on the duration of obesity but also on the age of onset. Obesity in children and adolescents affects almost all organ systems, including the endocrine, cardiovascular, gastrointestinal, reproductive, nervous, and immune systems. Obesity in children and adolescents affects growth, cognitive function, and psychosocial interactions during development, in addition to aggravating known adult comorbidities such as type 2 diabetes mellitus, hypertension, dyslipidemia, nonalcoholic fatty liver disease, obstructive sleep apnea, and cancer. Childhood and adolescent obesity are highly associated with increased cardiometabolic risk factors and prevalence of metabolic syndrome. The risk of cardiovascular and metabolic diseases in later life can be considerably decreased by even a small weight loss before the onset of puberty. Childhood and adolescent obesity is a disease that requires treatment and is associated with many comorbidities and disease burdens. Therefore, early detection and therapeutic intervention are crucial.

Abstract PDF

Headache is one of the most common neurological disorders in children and adults and can cause significant distress and disability in children and their families. The spectrum of pediatric headaches is broad, and the underlying etiology is variable. The symptoms and phenotypes of headaches in children may differ slightly from those in adults. It is important to have a good understanding of headaches in children and to distinguish between primary and secondary headaches through appropriate history assessment and neurological examination. Accurate diagnosis and appropriate drug selection are helpful for effective treatment. This article reviews headaches in children and adolescents, focusing on approaches for diagnosis and management.

Abstract PDF

Advances in perinatal and pediatric intensive care and recent advances in mechanical ventilation during the last two decades have resulted in an exponential increase in the number of children undergoing home mechanical ventilation (HMV) treatment. Although its efficacy in chronic respiratory failure is well established, HMV in children is more complex than that in adults, and there are more considerations. This review outlines clinical considerations for HMV in children. The goal of HMV in children is not only to correct alveolar hypoventilation but also to maximize development as much as possible. The modes of ventilation and ventilator settings, including ventilation masks, tubing, circuits, humidification, and ventilator parameters, should be tailored to the patient’s individual characteristics. To ensure effective HMV, education for the parent and caregiver is important. HMV continues to change the scope of treatment for chronic respiratory failure in children in that it decreases respiratory morbidity and prolongs life spans. Further studies on this topic with larger scale and systemic approach are required to ensure the better outcomes in this population.

Abstract PDF

Vedolizumab (VDZ) has been approved for the treatment of inflammatory bowel diseases (IBDs) in patients aged ≥18 years. We report a case of a pediatric patient with Crohn disease (CD) who was successfully treated with VDZ. A 16-year-old female developed severe active pulmonary tuberculosis (TB) during treatment with infliximab (IFX). IFX was stopped, and TB treatment was started. After a 6-month regimen of standard TB medication, her pulmonary TB was cured; however, gastrointestinal symptoms developed. Due to the concern of the patient and parents regarding TB reactivation on restarting treatment with IFX, VDZ was started off-label. After the second dose of VDZ, the patient was in clinical remission and her remission was continuously sustained. Ileocolonoscopy at 1-year after VDZ initiation revealed endoscopic healing. Therapeutic drug monitoring conducted during VDZ treatment showed negative antibodies to VDZ. No serious adverse events occurred during the VDZ treatment. This is the first case report in Korea demonstrating the safe and effective use of VDZ treatment in a pediatric CD patient. In cases that require recommencement of treatment with biologics after recovery of active pulmonary TB caused by anti-tumor necrosis factor agents, VDZ may be a good option even in pediatric IBD.

Abstract PDF

We report the case of a 16-month-old patient with chronic immune thrombocytopenia (ITP) patient who experienced delayed treatment-free response (TFR) after romiplostim treatment. He received intravenous immunoglobulin every month to maintain a platelet count above 20,000/μL for 2 years. Thereafter, he received rituximab and cyclosporine as second-line therapy, with no response, followed by romiplostim. After 4 weeks of treatment, the platelet count was maintained above 50,000/μL. Following 7 months of treatment, he discontinued romiplostim, and the platelet count decreased. His platelet counts remained above 50,000/μL, without any bleeding symptoms, 2 years after romiplostim discontinuation. This is the first report of TFR after romiplostim treatment in pediatric chronic ITP.

Abstract PDF

Background
Short stature is defined as a height below the 3rd percentile or more than two standard deviations below the mean for a given age, sex, and population. There have been inconsistent results regarding craniofacial morphology in short-statured children. This study aimed to analyze the differences between short-statured children with growth hormone deficiency, idiopathic short-statured children, and normal children.
Methods
Thirty-one short-statured children with growth hormone deficiency, 32 idiopathic short-statured children, and 32 healthy children were enrolled in this study. The measurements of their craniofacial structures from lateral cephalograms were evaluated.
Results
There were statistically significant differences among the three groups seven variables (anterior cranial base length, posterior cranial base length, total cranial base length, upper posterior facial height, posterior total facial height, mandibular ramus length, and overall mandibular length) in the linear measurement and five variables (saddle angle, gonial angle, mandibular plane angle, position of mandible, and maxilla versus mandible) in the angular measurement.
Conclusion
Compared to the control group, many linear and angular measurements of the craniofacial structures were significantly different in the two short-statured groups (p<0.05). Treatment plans by orthodontists should include these craniofacial structure characteristics.

Abstract PDF

Recurrent pericarditis is rare in children and is considered idiopathic in most cases. Its course is chronic, and preventing recurrences is important for the patient’s quality of life. Although a treatment strategy in pediatric recurrent pericarditis has not yet been established, non-steroidal anti-inflammatory drugs (NSAIDs) are the most common treatment for management of this condition, followed by corticosteroids, colchicine, immunosuppressive agents, immunoglobulins, and interleukin-1β receptor antagonists (e.g. anakinra). Herein, we report a case of recurrent pericarditis with pericardial effusion in a 5-year-old child who presented with fever and epigastric pain. He responded poorly to NSAIDs and corticosteroid therapy, but was successfully treated with colchicine.

Abstract PDF: Management of airway in a child with Cornelia de Lange Syndrome (CdLS) should be given due consideration because most of them have the problems related to difficult airway. The GlideScope video laryngoscope can be attempted during routine intubation, however it is mostly used in case of difficulty. With adequate preoperative airway assessment, we used the pediatric video laryngoscope as useful alternative airway device in a child with CdLS and orotracheal intubation proceeded uneventfully.

Abstract PDF: BACKGROUND
Respiratory viruses play a significant role in the etiology of acute respiratory infections and exacerbation of chronic respiratory illnesses. This study was conducted to identify the epidemiological and clinical characteristics of children with acute viral lower respiratory infections. METHODS: This study investigated 1,168 children diagnosed with acute viral lower respiratory tract infections (RTIs) between January 2012 and December 2014. Specimens of respiratory viruses were collected using a nasopharyngeal swab and analyzed by reverse transcriptase polymerase chain reaction. We retrospectively reviewed the medical records and analyzed the clinical features of children hospitalized for acute lower respiratory infections. RESULTS: Respiratory syncytial virus (RSV), the main cause of infection in children aged <5 years, was the most commonly detected pathogen in children with bronchiolitis and pneumonia, and resulted in high proportions of children requiring oxygen treatment and intensive care unit admission. Rhinovirus was preceded by RSV as the second most common cause of bronchiolitis and pneumonia, and was detected most frequently in the children aged ≥6 years. In addition, asthma was predominantly caused by rhinovirus in children aged ≥6 years, whereas croup was mostly caused by parainfluenza virus in those aged <5 years. Rhinovirus infection (p < 0.001) and history of asthma (p=0.049) were identified as significant risk factors for readmission within a month. CONCLUSION: We identified the epidemiological and clinical characteristics of respiratory viruses in children with acute lower respiratory infections during the last 3 years. Our findings may provide useful clinical insight to comprehend the acute viral lower RTIs in children.

Abstract PDF: BACKGROUND
Clinical differences in Mycoplasma pneumonia (MP) in children and adolescent patients according to abnormal infiltrate patterns on the chest X-ray were compared. METHODS: From 2012 to 2015, patients (n=336) diagnosed with MP at Yeungnam University Medical Center have been classified as eiher lobar pneumonia or bronchopneumonia based on the infilterate patterns observed on chest X-ray. Cases were analyzed retrospectively for gender, age, seasonal incidence rate, main symptoms (fever duration, extrapulmonary symptoms), and laboratory results, including white blood cell count, hemoglobin, platelets, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR), as well as concurrent respiratory virus infection. RESULTS: The following results were observed. First, lobar pneumonia affected 22.0% of all MP patients and was the most common in preschool children, with a high incidence rate in November and December. Second, lobar pneumonia had a longer fever duration than bronchopneumonia (p<0.001), and also showed significantly higher platelets (336.8 vs. 299.1 k/µL, p=0.026), ESR(46.3 vs. 26.0mm/hr, p<0.001) and CRP (4.86 vs. 2.18mg/dL, p=0.001). Third, viral co-infection was more common in bronchopneumonia (p=0.017), affecting 66.7% of infants and toddlers (p=0.034). Finaly, lobar consolidation was most common in both lower lobes. CONCLUSION: MP in children has increased in younger age groups, and the rate of lobar pneumonia with severe clinical symptoms is higher in older children.

Abstract PDF: BACKGROUND
As Mycoplasma pneumoniae pneumonia has increased in Korea, its relevance to infants, toddlers, and adolescents has magnified as well as. However, it is difficult to perform the serological test and PCR test routinely for diagnosis in actual clinical practice. Thus, the authors conducted this study to help clinicians do presumptive diagnosis of Mycoplasma pneumoniae pneumonia using clinical, radiological, and hematological findings. METHODS: The study population consisted of 224 children between 1 month and 14 years old, hospitalized for radiographically confirmed pneumonia. Patients were divided into two groups of 100 children with Mycoplasma pneumoniae pneumonia, as diagnosed using the ELISA method. Groups with negative result in Mycoplasma IgM antibody test were classified into the viral group (98 patients with respiratory virus) and the bacterial group (46 patients with the bacteria detected in the blood sputum culture or antibiotic treatment except macrolide improved the patient's condition). These groups were compared and analyzed using clinical, hematological,and radiographic differences and scoring system. RESULTS: Clinical, hematological, and radiographic characteristics of Mycoplasma pneumoniae pneumonia have shown the intermediate level results between bacterial pneumonia and viral pneumonia. In terms of scoring system, the mean score of Mycoplasma pneumoniae pneumonia was 4.23, which was the intermediate level between bacterial pneumonia (mean score=6.67) and viral pneumonia (mean score=1.48). CONCLUSION: Results suggest that the combination of the scoring system information can increase the accuracy in the diagnosis even if they may have difficulties on diagnosis, because clinical manifestations, hematological, and radiographic findings are nonspecific.

Abstract PDF: More and more children are becoming obese and overweight due to several factors that include a high energy density in the diet (a high fat intake) and low energy expenditure. Consequently childhood obesity is becoming a significant health problem. Fat tissue releases many cytokines such as resistin, tumor necrosis factor-alpha, leptin, interleukin-6. These adipocytokines induce obesity-related insulin resistance. Insulin resistance is a key component of obesity-related metabolic problems such as hypertension, type 2 diabetes mellitus, dyslipidemia, non-alcoholic steatohepatitis, acanthosis nigricans and polycystic ovarian syndrome. This review article focused on insulin resistance and its related metabolic diseases.

Abstract PDF: PURPOSE: To evaluate the chemokine expression in children with a non-productive cough. MATERIALS AND METHODS: Six children with a non-productive cough who visited Yeungnam University Hospital were evaluated for the mRNA expression of interferon-gamma-inducible protein 10(IP-10), macrophage cationic protein 1 and 3 (MCP-1, 3), interleukin (IL)-8, regulated upon activation in normal T cells expressed and secreted (RANTES), eotaxin and growth-related oncogene-alpha (Gro-alpha) using the reverse transcription polymerase chain reaction. RESULTS: The chemokines IP-10 and MCP-3 were expressed in all samples. The chemokine RANTES was expressed in five cases, and IL-8 was expressed in three among them. However, eotaxin, Gro-alpha and MCP-1 were not expressed at all. The expression of chemokine MCP-3, RANTES and IL-8 were suppressed after the resolution of coughing in just one available case. CONCLUSION: The chemokines MCP-3, RANTES and IL-8 may contribute to airway inflammation in children with a non-productive cough, whereas IP-10 is of secondary importance in this condition.

Abstract PDF: Pediatric bipolar disorder(BD) is one of the significant psychiatric health problems, which begins in childhood, has chronic persisting clinical course and leads impairs academic, occupational and legal problems of the patients. Fortunately, there has been increasing recognition of pediatric bipolar disorder during the past 10 years, even there are still controversy about clinical features and diagnosis. The clinical presentation of pediatric BD is greatly different to classic BD, relatively higher percentage of mixed, rapid cycling subtypes, not episodic and chronic lasting nature. In addition, pediatric BD has many comorbid psychiatric conditions such as attention deficit hyperactivity disorder, anxiety disorder and that makes more difficult to treat the patients with pediatric BD. To reduce confusion about diagnosis, the National Institute of Mental Health Research Roundtable divided pediatric BD into narrow and broad phenotype. 1) Given the paucity of medication trial studies of pediatric BD, no psychotrophic medications have been approved by U.S. Food and Drug Administration, except lithium. There have been a few open trials and retrospective chart reviews on the efficacy and side effects of mood stabilizers, anticonvulsants and atypical antipsychotics. More short and long-term randomized, double blind, well controlled trials of medication for pediatric BD are needed.

Abstract PDF: BACKGROUND
The causes of ADHD(attention deficit hyperactivity disorder) are various, it is impossible to understand the whole characteristics of ADHD, only with simple intellignece testing scales. We compared cognitive characteristics of ADHD group with normal controls with Korean Kaufman Assessment Battery for Children(K-ABC), It is well known to evaluate neuropsychological and cognitive aspects of the children. MATERIALS AND METHODS: Age and sex matched 40 ADHD patients and 40 normal controls tested with the K-ABC. Each subscales compared between pre-treatment patients and controls, pre-treatment and post-treatment in patient group, post-treatment patients and controls. RESULTS: Significant differences are ovserved in sequential processing, simultaneous processing, cognitive processing and achievement between pre-treatment patients and controls, and in gestalt closure between pre-treatment and post-treatment patients group. But there are no significant differences between pre-treatment patients and controls in gestalt closure and reading/decoding. CONCLUSIONS: Methylphenidate improved the scores of simultaneous scale, which means improvement of executive functions such as divided attention, analysis and organization. Methylphenidate also reduced distractibility.

Abstract PDF: The purpose of this study was to examine the reliability and validity of a Korean form of Childhood Attention Problem(CAP) scale. CAP were administered to 98 normal elementary school students as control group and 98 attention deficit hyperactivity disorder patients. Male students showed high scores than female students in both subscale and total scores, but not statistically significant. There were no significant difference in CAP scale between male students and female students in attention deficit hyperactivity disorder patients. In the reliability test, the test-retest reliability coefficient was highly satisfactory and that of inattention subscale was 0.83, impulsivity subscale was 0.70 and total score was 0.82. In the reliability test by internal consistency, the Cronbach a coefficient was highly satisfactory and that of inattention subscale was 0.91, overactivity subscale was 0.89(p<0.05). The concurrent validity between CAP scale and ADDES-HV scale was 0.85 in attention deficit hyperactivity disorder patient group and 0.73 in normal control group(p<0.05). In discriminant validity test between attention deficit hyperactivity disorder patient group and normal control group, the patient group showed higher score(p<0.05). The total discriminant capacity of the patient group in CAP was 93.4%. In this point of view, CAP scale showed high reliability and validity in applying to Korean subjects and was proved to be the good and simple screening test tool for attention deficit hyperactivity disorder research and can help many young patient to treat early.

Abstract PDF: This study was conducted to explore the feasibility of using the lead level in the hair of children as a screening test for lead intoxication of children and as an indicator for environmental pollution. Lead concentration of hair was measured for 268 seven to nine-year-old elementary school children in Taegu city (147 children) and Gampo. town(121 children). The lead level in hair was measured by atomic absorption spectrophotometer equipped with a graphite furnace atomizer. The following information was obtained for all children : sex, age, father's occupation and smoking habits, kinds of hair cleaner, fingernail biting habits, and status of the child's hands and clothing. The mean lead level in hair was 8.7+/-2-9 microg/g in the urban area and 7.7+/-2.2 pg/g in the rural area. There were significant differences between two groups(p(0.01). The difference of lead levels in hair measured by cleanliness of the child's hands (clean : 7.4+/- 2.7 pg/g, dirty : 8.2+/- 2.6 pg/g) and child's clothing(clean : 8.0+/- 2.5 microg/g, dirty : 9.3+/- 2.6 microg/g) were statistically significant, but other factors were not significant. In multiple regression analysis, difference of residency and age were significant variables for lead level in the hair of children. These findings suggest that measurement of lead level in the hair is a useful method for the screening of the lead intoxication of children and monitoring environmental conditions.

Abstract PDF

Delayed emergence of speech or language are frequent causes for concern about development during early childhood. Delay in evaluation and proper management until school entry in more likely to result in frustration, anxiety and school failure. Many language disturbances and their attendant behavior disorders respond to intensive language therapy. Authors analyzed the medical records of 52 children with delayed language development evaluated during 30 months from January 1986 through June 1988. The results were as follows: 1. The majority of cases were evaluated at the age of 2-2.9 year old (16 cases, 30.8%) and 3-3.9 year old (11 cases, 21.2%) 2. Male to female ratio was 3:1 3. The most common cause was mental retardation (53.8%), followed by developmental language disorder (23.1%) and autism (13.5%) 4. The most common associated condition was dysarticulation (17.3%), followed by strabismus (9.6%) and seizures (7.7%) 5. Special education was recommended in cases of 23 (44.2%), speech therapy in 12 cases (23.1%) and consultation to child psychiatry in 7 cases (13.5%) Making diagnosis of underlying disorders in not simple because assessment of intelligence in young children in difficult and only a few tests are standardized. More detailed study on children with delayed language development and development of psychometric tests for handicapped children are necessary, especially in Korea.

Abstract PDF: Childhood epilepsy which has high prevalence rate and inception rate is one of the commonest problem encountered in pediatrician. In contrast with epilepsy of adult, in childhood epilepsy, more variable and varying manifestations are found because the factors of age, growth and development exert their influences in the manifestations and the courses of childhood epilepsy. Moreover epilepsy children have associated problems such as physical and mental handicaps, psychological disorders and learning disability. For these reasons pediatrician who deals with epileptic children experiences difficulties in making diagnosis and managing them. In order to improve understanding and management of childhood epilepsy, authors reviewed 103 cases of epileptic patients seen at pediatric department of Yeungnam University Hospital retrospectively. The patients were classified according to the type of epileptic seizure. Suspected causes of epilepsy, associated conditions of epileptic patients, age incidence and the findings of brain CT were reviewed. Large numbers of epileptic patients (61.2%) developed their first seizures under the age of 5. The most frequent type of epileptic seizure was generalized tonic-clonic, tonic, clonic seizure (49.5%), followed by simple partial seizure with secondary generalization (17.5%), simple partial seizure (7.8%), atypical absence (5.8%) and unclassified seizure (5.8%). In 83.5% of patients, we could not find specific cause of it, but in 16.5% of cases, history of neonatal hypoxia (4.9%), meningitis (3.9%), prematurity (1.9%), small for gestational age (1.0%), CO poisoning (1.0%), encephalopathy (1.0%) were found. 30 cases of patients had associated diseases such as mental retardation, hyperactivity, delayed motor milestones or their combinations. The major abnormal findings of brain CT performed in 42 cases were cortical atrophy, cerebral infarction, hydrocephalus and brain swelling. This review stressed better designed classification of epilepsy is needed and with promotion of medical care, prevention of epilepsy is possible in some cases. Also it is stressed that childhood epilepsy requires multidisciplinary therapy and brain CT is helpful in the evaluation of epilepsy with limitation in therapeutic aspects.

Abstract PDF: BACKGROUND
Neutropenic fever is one of the most common and potentially severe complications of chemotherapy in pediatric oncology patients, while urinary tract infection (UTI) is one of the most prevalent bacterial infections in these patients. Therefore, this study was conducted to investigate features of UTI with neutropenic fever in pediatric oncology patients. METHODS: We retrospectively reviewed and analyzed the medical records, laboratory results and image findings of cases of neutropenic fever in the Department of Pediatrics of Yeungnam University Medical Center, South Korea between November 2013 and May 2015. Episodes were divided into two groups, UTI vs. non-UTI group according to the results of urine culture. The results were then compared between groups. The analysis was performed using IBM SPSS 23.0. A p-value <0.05 was considered to indicate a significant difference between groups. RESULTS: Overall, 112 episodes of neutropenic fever were analyzed, among which 22 episodes (19.6%) showed organisms on urine culture and were classified as UTI. The remaining 90 episodes were classified as non-UTI. Only four episodes (18.2%) of the UTI group showed pyuria on urine analysis. In the UTI group, 76.5% were sensitive to the first line antibiotics and showed higher clinical response than the non-UTI group. Among hematologic malignancy patients, the UTI group revealed higher serum β 2-microglobulin levels than the non-UTI group (1.56±0.43 mg/L vs. 1.2±0.43 mg/L, p<0.028). CONCLUSION: UTI in pediatric neutropenic fever responds well to antibiotics. Hematologic malignancy cases with UTI reveal increased serum β2-microglobulin level. These results will be helpful to early phase diagnosis of UTI.
