PurposeTo evaluate the clinical characteristics of vitamin D deficiency and its association with iron deficiency anemia (IDA).MethodsA total of 171 children aged less than two years underwent 25-hydroxyvitamin D3 tests between January 2007 and July 2009. The study was classified into two groups: normal and vitamin D insufficiency, by their vitamin 25-hydroxyvitamin D3 levels.ResultsIn total, 120 children were in the normal group (mean age, body weight and heights 12.5±7.0, 9.3±0.9 kg and 76.8±1.1 cm), and 51 children in the vitamin D insufficiency group (9.9±5.4 months, 9.0±0.9 kg and 75.1±0.9 cm). Vitamin D insufficiency was most commonly diagnosed in the spring (44%). The proportion of complete breast-feeding was higher in the insufficiency (92%), and 25.5% of the children in the deficient group also experienced IDA compared that 12% of normal group. Ten children in the insufficiency group experienced bony changes. Six children received calcitriol medication in the normal group, in whom the mean vitamin 25-hydroxyvitamin D3 level increased from 39.6±14.6 ng/mL (pre-medication) to 41.8±17.2 ng/mL (post-medication), and 13 in the insufficiency group, in whom the mean vitamin 25-hydroxyvitamin D3 increased from 20.7±7.0 ng/mL to a mean post-treatment level of 43.7±23.8 ng/mL.ConclusionThis study demonstrated that approximately 30% of children aged ≤2 years experienced vitamin D insufficiency associated with subclinical rickets. Many children also experienced concurrent IDA. Guidelines for vitamin D supplement in such children must therefore be established.

Obstructive sleep apnea (OSA) in children is a frequent disease for which optimal diagnostic methods are still being defined. Treatment of OSA in children should include providing space, improving craniofacial growth, resolving all symptoms, and preventing the development of the disease in the adult years. Adenotonsillectomy (T&A) has been the treatment of choice and thought to solve young patient's OSA problem, which is not the case for most adults. Recent reports showed success rates that vary from 27.2% to 82.9%. Children snoring regularly generally have a narrow maxilla compared to children who do not snore. The impairment of nasal breathing with increased nasal resistance has a well-documented negative impact on early childhood maxilla-mandibular development, making the upper airway smaller and might lead to adult OSA. Surgery in young children should be performed as early as possible to prevent the resulting morphologic changes and neurobehavioral, cardiovascular, endocrine, and metabolic complications. Close postoperative follow-up to monitor for residual disease is equally important. As the proportion of obese children has been increasing recently, parents should be informed about the weight gain after T&A. Multidisciplinary evaluation of the anatomic abnormalities in children with OSA leads to better overall treatment outcome.

Background: Although the benefits of breastfeeding are broadly acknowledged with the efforts of the government and several medical societies, the rate of exclusive breastfeeding through 6 months is lower in Korea than in developed countries.Purpose: This study aimed to investigate pediatricians’ perceptions of breastfeeding barriers and the current breastfeeding counseling environment and propose government policies to encourage breastfeeding in Korea.Methods: Fourteen survey questions were developed during meetings of Korean Society of Breastfeeding Medicine experts. The Korean Pediatric Society emailed a structured questionnaire to domestic pediatricians registered as official members of the Korean Pediatric Society on May 4, 2021, and June 3, 2021. This study examined the survey responses received from 168 pediatricians.Results: The 168 respondents included 62 professors, 53 paid doctors, and 53 private physicians. Breastfeeding was recommended by 146 Korean pediatricians (86.9%). However, only 99 responders (59%) currently provide breastfeeding counseling in hospitals. Most respondents stated providing less than 15 minutes of breastfeeding counseling time in the clinic. Moreover, 89.88% of the respondents responded that they would participate in breastfeeding counseling education if an appropriate breastfeeding counseling program was newly established.Conclusion: This study showed that, although Korean pediatricians had a positive attitude toward breastfeeding, limited counseling was provided for parents. Along with policy support to improve the medical environment through the establishment of an appropriate breastfeeding counseling program, high-quality counseling and an increased breastfeeding rate are expected.

Pediatrics, Perinatology and Child Health ,Pediatrics - Abstract
The recent re-emergence of vitamin D deficiency (VDD) and rickets among breastfed infants without adequate sunlight exposure and vitamin D supplementation has been reported worldwide. Breastfed infants are particularly vulnerable to VDD because of the low vitamin D content of breast milk, restricted sunlight exposure, increased pollution, and limited natural dietary sources of vitamin D. The prevalence of VDD in breastfed infants differs vastly between studies and nations at 0.6%–91.1%. The recommended intake of vitamin D for lactating mothers to optimize their overall vitamin D status and, consequently, of their breast milk is 200–2,000 IU/day, indicating a lack of consensus. Some studies have suggested that maternal high-dose vitamin D supplementation (up to 6,400 IU/day) can be used as an alternate strategy to direct infant supplementation. However, concern persists about the safety of maternal high-dose vitamin D supplementation. Direct infant supplementation is the currently available option to support vitamin D status in breastfed infants. The recommended dose for vitamin D supplementation in breastfed infants according to various societies and organizations worldwide is 200–1,200 IU/day. Most international guidelines recommend that exclusively or partially breastfed infants be supplemented with 400 IU/day of vitamin D during their first year of life. However, domestic studies on the status and guidelines for vitamin D in breastfed infants are insufficient. This review summarizes the prevalence of VDD in breastfed infants, vitamin D content of breast milk, and current guidelines for vitamin D supplementation of lactating mothers and infants to prevent VDD in breastfed infants.

Background: Breastfeeding reportedly reduces the overall frequency of infections. Respiratory syncytial virus (RSV), the most common respiratory pathogen in infants, involves recurrent wheezing and has a pathogenic mechanism related to airway structural damage.Purpose: This study aimed to investigate whether breastfeeding has a beneficial effect against RSV-induced respiratory infection compared to formula feeding among infants in Korea.Methods: We retrospectively reviewed the medical records of infants under 1 year of age who were admitted with RSV infection between January 2016 and February 2018 at the department of pediatrics of 4 hospitals. We investigated the differences in clinical parameters such as cyanosis, chest retraction, combined infection, fever duration, oxygen use, oxygen therapy duration, intensive care unit (ICU) admission, and corticosteroid treatment of exclusive breast milk feeding (BMF), artificial milk formula fed (AMF), and mixed feeding (MF) groups.Results: Among the 411 infants included in our study, 94, 161, and 156 were included in the BMF, MF, and AMF groups, respectively. The rates of oxygen therapy were significantly different among the BMF (4.3%), MF (8.1%), and AMF (13.5 %) groups (P=0.042). The odds ratios (ORs) for oxygen therapy was significantly higher in the AMF group than in the BMF group (adjusted OR, 3.807; 95% confidence interval, 1.22–11.90; P=0.021). The ICU admission rate of the BMF group (1.1%) was lower than that of the MF (3.5%) and AMF (4.5%) groups; however, the dissimilarity was not statistically significant (P=0.338).Conclusion: The severity of RSV infection requiring oxygen therapy was lower in the BMF than the AMF group. This protective role of human milk on RSV infection might decrease the need for oxygen therapy suggesting less airway damage.

Purpose : The rate of drug-resistant tuberculosis (DR-TB) in children is an indicator of the effectiveness of TB control programs in the community. This study aimed to assess the prevalence of DR-TB in children and evaluate TB management. Methods : Between January 1999 and July 2007, drug susceptibility tests for anti-TB drugs were employed for patients aged less than 19 years with culture-positive TB. Results : A total of 607 cases (16.6%) were resistant to at least one anti-TB drug as follows: isoniazid (INH; 13.8%), rifampin (8.9%), pyrazinamide (4.2%), streptomycin (3.7%), ethambutol (EMB; 5.9%), and para-aminosalicylic acid (PAS; 1.9%). Multidrug-resistant (MDR) TB was found in 276 cases (7.6%); extensive drug resistant (XDR) TB, in 5 cases (0.2%). The rate of resistance to at least one anti-TB drug in children aged >15 years (16.1%) was significantly lower than that in children aged

Restless legs syndrome (RLS) is a common neurological sleep disorder in adults characterized by the following diagnostic criteria: an urge to move that is usually associated with unpleasant sensations and symptoms that are worse at rest, relieved by movement, and most severe at night. The definite diagnosis of RLS in children is stricter and consists of self-description of leg discomfort or the presence of 2 of 3 supportive criteria combined with 4 essential criteria for diagnosis in adults. RLS in childhood has often been misdiagnosed as growing pains or a part of normal development. As a result, physicians have often missed the chance for proper management. We diagnosed a case of RLS in a 5-year-old boy presenting with growing pains, whose mother was found to have had RLS since childhood. We confirmed RLS by using a polysomnograph, in which the indices of periodic limb movement syndrome (PLMS) and periodic limb movement during wakefulness (PLMW) were recorded to be compatible with RLS criteria. The patient‘s ferritin level was low normal, and his symptoms improved after taking iron supplements.

Purpose : Vitamin D plays a key role in bone mineralization of the skeleton and vitamin D deficiency can lead to rickets. It is well known that vitamin D deficiency is common in breast fed infants. Of these patients, clinically, some have no signs of rickets, but laboratory and radiographic findings are diagnostic for vitamin D deficiency rickets (subclinical vitamin D deficiency rickets). The purpose of this study is to clarify current causes and ways to prevent this disease. Methods : We reviewed the clinical and laboratory characteristics of children who were incidentally diagnosed as subclinical rickets during treatment of other disease such as pneumonia, gastroenteritis, urinary tract infection at Eulji Hospital, Seoul, Korea from March, 2003 to July 2007. Results : Eight patients (six boys and two girls) were diagnosed with subclinical vitamin D deficiency rickets. The mean age of the patients was 12.6±5.8 months, and they were diagnosed from January to July. The associated diseases were pneumonia, urinary tract infection, acute gastroenteritis, and iron deficiency anemia. All patients were breast-fed. Two showed growth failure. The mean serum alkaline phosphatase was 1995.8±739.5 IU/L, the mean calcium count was 9.5±0.6 mg/ dL, and the mean phosphorus content was 3.6±1.5 mg/dL mg/dL. The mean intact parathyroid hormone was 214.8±155.9 pg/mL (reference range, 9-65), the mean 1,25-dihydroxyvitamin D was 82.4±49.3 pg/mL (reference range, 2070), and the mean 25-hydroxyvitamin D was 29.6±10.6 ng/mL (reference range, 1030). A radiographic examination showed cupping, fraying, and flaring of metaphyses in all patients. Six patients were administered calcitriol (400 IU/day) for three months. A consequent radiographic and laboratory examination showed improvement. The first two patients were initially diagnosed with metaphyseal dysplasia, without the detection of vitamin D deficiency and they spontaneously improved without vitamin D supplements. However, two years later, they showed mild scoliosis and metaphyseal dysplasia, respectively. Conclusion : Breast-feeding without supplementation involves high risk of vitamin D deficiency. Some infants may also develop rickets; therefore, such groups should be considered for vitamin D supplementation.

We report clinical, cytogenetic, and fluorescence in situ hybridization (FISH) studies of a patient with ring chromosome 9. She presented with failure to thrive, facial dysmorphysm and mild psychomotor development delay in the absence of major malformations. Peripheral blood karyotype of the patient was 46,XX,r(9)(p24q34). G-band analysis suggested no loss of material in the ring chromosomes. FISH analysis using the subtelomere-specific sequences on chromosome 9p and 9q, revealed 46,XX,r(9)(p24q34),ish r(9)(D9S913-,D9S325+). Failure to detect any hybridization of a probe for the subtelomeric sequences in the ring 9p terminal suggested that this ring arose from breakage in the distal short arm. The cytogenetic and FISH data in our case provided further evidence for the existence of a "complete ring" phenotype with incomplete subtelomeric sequences.

Purpose : To determine whether primary snoring could be distinguished from obstructive sleep apnea syndrome (OSAS) by clinical evaluation and symptom scores. Methods : 56 snoring and 20 asymptomatic subjects were recruited and polysomnography was used to confirm that there were 39 OSAS, 17 primary snoring, and 20 control subjects. We evaluated the size of the childrens adenoids and tonsils. Parents completed sleep disordered breathing scale (SDBS) and obstructive sleep apnea 18 (OSA-18) questionnaires for use as symptom scores, as well as an attention deficit hyperactivity disorder rating scale-IV (ADHD RS-IV). Results : There were no differences between primary snoring and OSAS in terms of tonsil and adenoid size, SDBS (9.4±4.6 vs 10.8±4.5), and OSA-18 score (61.1±25.1 vs 71.2±8.4). The patients with OSAS (15.8±7.9) and PS (22.2±9.4) had a higher ADHD RS-IV score than the control subjects (2.9±3.3). There was no difference in the ADHD RS-IV scores of patients with primary snoring and OSAS. Conclusion : We confirmed that clinical evaluation could not distinguish OSAS and primary snoring. In addition, our study suggests that primary snoring as well as OSAS is associated with attention deficit hyperactivity disorder.

Purpose : The most common causes of acute viral gastroenteritis in newborn period are rotavirus, astrovirus, norovirus and enteric adenovirus. This study was designed to investigate the clinical characteristics, clinical symptoms, isolation rate and distribution of these viruses in full-term neonates during neonatal period. We also studied the influence on the viral isolation rate by postnatal care place and feeding type. Methods : We evaluated 112 healthy full-term neonates who were admitted to Eulji hospital, presenting with symptoms of acute viral gastroenteritis from September 2004 to August 2005. Epidemiologic, clinical and laboratory data were reviewed. Enzyme-linked immunosorbent assay (ELISA) for rotavirus, astrovirus and norovirus and RT-PCR for enteric adenovirus were performed in study subjects.Results : The mean age at the admission was 11.4±5.4 days, mean weight loss was 5.9±5.1%, mean hospitalization duration was 6.3±3.4 days. Moderate and severe weight loss were expressed in 51.7% and metabolic acidosis was in 13.4%. The percent of living in postnatal care facility (PCF) was 74.1 % and the percent of mixed feeding was 64.3%. Isolation rate of virus was 33%. The most prevalent virus was rotavirus (59.5%), followed by astrovirus (29.7%) and norovirus (10.8%). There was no differences in virus isolation rate by postnatal care place and by feeding type. The rotavirus was main virus in both home group and PCF group. But astrovirus was more detected in PCF and norovirus was more detected in home (P

Purpose:The purpose of this study was to investigate the health status and nutritional condition of children living in a low-income community through anthropometric, laboratory evaluation. Methods:A community-based survey identified children below 15 years living in a low-income community. Their weight, height, visual acuity, hearing level and dental status were measured. Blood sample were obtained on June and July, 2004. Hemoglobin, serum cholesterol, Hepatitis B antigen/ antibody, AST and ALT were measured. Results:A total of 285 students(M:F=141:144) aged 6 to 14 years were included in this study. The heights and weights in some grades were smaller than controls. The prevalence of obesity was 10.6 percent in males and 10.7 percent in females. The prevalence of abnormal visual acuity, hearing impairments and dental carries were 20.5 percent, 0.3 percent and 69.4 percent. The prevalence of anemia was 10.1 percent. Serum total cholesterol was over 200 mg/dL in 7 percent. They complained of abdominal pain(22.1 percent) and headache(17.1 percent). Hyperthyroidism, cataract, neurofibromatosis, severe atopic dermatitis, ventricular septal defect, strabismus and inguinal hernia were newly diagnosed. Conclusion:Mean heights and weights of children in the low-income community were smaller than controls. The prevalence of abnormal visual acuity, hearing impairment and dental carries were higher than in the 2003 national health survey. Additional research is needed to evaluate the health status of the low-income community.
