Background@#Over the last decade, extracorporeal membrane oxygenation (ECMO) use in critically ill children has increased and is associated with favorable outcomes. Our study aims to evaluate the current status of pediatric ECMO in Korea, with a specific focus on its volume and changes in survival rates based on diagnostic indications. @*Methods@#This multicenter study retrospectively analyzed the indications and outcomes of pediatric ECMO over 10 years in patients at 14 hospitals in Korea from January 2012 to December 2021. Four diagnostic categories (neonatal respiratory, pediatric respiratory, postcardiotomy, and cardiac-medical) and trends were compared between periods 1 (2012–2016) and 2 (2017–2021). @*Results@#Overall, 1065 ECMO runs were performed on 1032 patients, with the annual number of cases remaining unchanged over the 10 years. ECMO was most frequently used for post-cardiotomy (42.4%), cardiac-medical (31.8%), pediatric respiratory (17.5%), and neonatal respiratory (8.2%) cases. A 3.7% increase and 6.1% decrease in pediatric respiratory and post-cardiotomy cases, respectively, were noted between periods 1 and 2.Among the four groups, the cardiac-medical group had the highest survival rate (51.2%), followed by the pediatric respiratory (46.4%), post-cardiotomy (36.5%), and neonatal respiratory (29.4%) groups. A consistent improvement was noted in patient survival over the 10 years, with a significant increase between the two periods from 38.2% to 47.1% (P = 0.004). Improvement in survival was evident in post-cardiotomy cases (30–45%, P = 0.002).Significant associations with mortality were observed in neonates, patients requiring dialysis, and those treated with extracorporeal cardiopulmonary resuscitation (P < 0.001). In pediatric respiratory ECMO, immunocompromised patients also showed a significant correlation with mortality (P < 0.001). @*Conclusion@#Pediatric ECMO demonstrated a steady increase in overall survival in Korea;however, further efforts are needed since the outcomes remain suboptimal compared with global outcomes.

Microscopic polyangiitis (MPA) is a small vessel vasculitides mostly associated with anti-neutrophil cytoplasmic antibodies (ANCA). The kidney is the most commonly affected organ in MPA. We report the case of a 9-year-old girl with ANCA-negative MPA who initially presented with respiratory symptoms, including cough, sputum, and dyspnea. Based on her symptoms, atypical pneumonia was suspected. Also, childhood interstitial lung disease was considered based on findings seen on chest CT. Despite initial improvement of symptoms with oral corticosteroid therapy, dyspnea with initiation of corticosteroid tapering was noted. A final diagnosis of MPA was made after lung biopsy. ANCA was negative in both the initial and repeat blood tests. Oral cyclophosphamide and prednisolone treatments led to full remission. Since then, the patient has been treated with low dose prednisolone and azathioprine for maintenance. A good treatment response was achieved and her clinical symptoms, pulmonary functions, and radiologic findings have since improved. Thus, early and precise diagnosis of MPA is crucial for remission induction and prevention of symptom relapse.

Pierre Robin sequence (PRS), also called Robin sequence, is a congenital anomaly characterized by a triad of micrognathia, glossoptosis, and upper airway obstruction. Infants with PRS can present with varying degrees of respiratory difficulty secondary to upper airway obstruction. There has been no consensus for the treatment of upper airway obstruction in infants with PRS, but recent studies recommend attempting non-surgical interventions before surgical treatment. In this case report, we present 3 cases of infants diagnosed with PRS who showed persistent respiratory difficulties after birth. Before considering surgical intervention, insertion of a nasopharyngeal airway was attempted in these infants. Following this procedure, symptoms of upper airway obstruction were relieved, and all infants were discharged without surgical interventions; the nasopharyngeal airway was removed 1 to 2 months later. To date, no infant has shown signs of upper airway obstruction. Nasopharyngeal airway insertion is a highly effective and less invasive treatment option for infants with PRS. However, it is not widely known and used in Korea. Nasopharyngeal airway insertion can be preferentially considered before surgical intervention for upper airway obstruction in such infants.

Although the etiology of moyamoya disease (MMD) remains unknown, autoimmunity is one of the proposed pathogeneses. Unlike other autoimmune disorders that are associated with cerebral arteritis, concurrence of MMD and diabetes mellitus (DM) is rare. However, we encountered a patient with concurrent diabetic ketoacidosis (DKA) and acute ischemic stroke due to MMD. Our patient was diagnosed with glutamic acid decarboxylase antibody-positive type 2 DM (T2DM) based on laboratory and physical examination findings. Brain magnetic resonance images revealed an acute ischemic stroke in the left cerebral hemisphere and bilateral diffuse stenosis/occlusion in the middle cerebral artery and multiple collaterals. Thus, here, we report a patient with both T2DM and MMD who developed an acute ischemic stroke that was complicated by DKA.

PURPOSE: For 3 consecutive years from 2012–2014, we analyzed the causative factors for why the Jeju Island had the highest obesity prevalences of school children among the 15 provinces in Korea. METHODS: From our analysis of 28,026 elementary school children with obesity or normal weight in the 15 provinces, we analyzed 12 factors related to eating habits, exercise habits, lifestyle, and mental health. The differences between the obese and normal weight children were researched. Finally, Jeju was compared with Seoul, which has the lowest obesity prevalence in school age children. Statistical analysis was performed using the chi square test of PASW Statistics ver. 18.0. RESULTS: Compared to the normal weight group, the obese group had significantly higher rates of consuming soft drinks (p<0.001), fast food intake (p=0.019), skipping breakfast (p<0.001), insufficient sleep (p<0.001), bullying experiences (p=0.001) and runaway impulses (p=0.012). Compared to Seoul, Jeju Island had significantly higher rates of Ramen intake (3.4% vs. 5.4%, p=0.021) and meat intake (46.0% vs. 52.9%, p=0.003). On the other hand, Jeju Island was significantly lower than was Seoul in their fruit intake (83.4% vs. 67.1%, p<0.001), vegetable intake (71.4% vs. 64.2%, p=0.001), and intense physical activity (63.4% vs. 47.7%, p<0.001). Meanwhile, insufficient sleep (15.4% vs. 9.6%, p<0.001) and runaway impulses (5.6% vs. 3.3%, p=0.027) in children were significantly lower in Jeju Island than in Seoul. CONCLUSION: The results of the obesity factor analysis of elementary school students in Jeju Island can be used as useful educational material for lowering the obesity prevalence in Jeju community.

Kidney length is the most useful parameter for clinical measurement of kidney size, and is useful to distinguish acute kidney injury from chronic kidney disease. In this prospective observational study of 437 normal children aged between 0 and < 13 years, kidney length was measured using sonography. There were good correlations between kidney length and somatic values, including age, weight, height, and body surface area. The rapid growth of height during the first 2 years of life was intimately associated with a similar increase in kidney length, suggesting that height should be considered an important factor correlating with kidney length. Based on our findings, the following regression equation for the reference values of bilateral kidney length for Korean children was obtained: kidney length of the right kidney (cm) = 0.051 × height (cm) + 2.102; kidney length of the left kidney (cm) = 0.051 × height (cm) + 2.280. This equation may aid in the diagnosis of various kidney disorders.

PURPOSE: To analyze the associations among the degrees of nonalcoholic fatty liver disease (NAFLD) by ultrasonography and metabolic syndrome, degrees of obesity in children, and degrees of parental obesity. METHODS: A total of 198 children with obesity who visited a pediatric obesity clinic were prospectively enrolled in this study. The severity of NAFLD based on ultrasonography was classified into no, mild, moderate, or severe NAFLD group. The degree of obesity based on the percentage over standard weight for height per sex was classified into mild, moderate, or severe. RESULTS: Of 132 patients evaluated for the degree of NAFLD and metabolic syndrome, the p-value of correlation between the two factors was 0.009. Therefore, metabolic syndrome might significantly affect the degree of NAFLD. Of 158 patients evaluated for the degree of NAFLD and the degree of obesity, the p-value of correlation between the two factors was 0.122. Of 154 patients evaluated for the degree of obesity and father's obesity, the p-value was 0.076. Of 159 patients evaluated for the degree of obesity and mother's obesity, the p-value was 0.000, indicating that mother's obesity could significantly affect the degree of obesity in children. Of 142 patients evaluated for the degree of obesity and metabolic syndrome, the p-value was 0.288. CONCLUSION: Metabolic syndrome might significantly affect the degree of nonalcoholic fatty liver in children. In addition, mother's obesity might be a significant factor that affects the degree of obesity in children.

Although liver function test abnormality is frequently noted in children, there is no report about the distribution of the etiology and natural recovery time of the abnormal liver function. From March 2005 to February 2014, clinical information was retrospectively collected from 559 children who had abnormal liver function and were hospitalized or visited the outpatient clinic at the Jeju National University Hospital. The etiology of abnormal liver function was classified into groups and the natural recovery time of abnormal liver function was analyzed. The etiological groups of 559 patients included 'nonspecific hepatitis' in 42 (7.5%), 'infection' in 323 (57.8%), 'rheumatologic and autoimmune' in 66 (11.8%), 'nonalcoholic fatty liver disease' in 57 (10.2%), 'anatomic' in 12 (2.1%), 'toxic' in 13 (2.1%), 'metabolic' in 8 (1.4%), 'hematologic' in 7 (1.3%), 'hemodynamic' in 4 (0.7%), and 'others' in 27 (4.8%). Among the 'infection' group (57.8%), the 'viral infection in the respiratory tract' subgroup, which had 111 patients (19.8%), was the most common. The natural recovery time of the abnormal liver function was 27 days (median) in 'nonspecific hepatitis', 13 days (median) in 'viral respiratory tract disease', 16 days (median) in 'viral gastroenteritis', 42 days (median) in 'viral febrile illness", and 7 days (median) in "Kawasaki disease". The information on the natural recovery time of abnormal liver function may help the physician to perform good clinical consultation for patients and their parents.

BACKGROUND: Pulmonary tuberculosis is an infectious disease of the lungs caused by Mycobacterium tuberculosis complex (MTB) designated by law in Korea, and accurate diagnosis and urgent treatment are necessary for the maintenance of public health. Recently, nontuberculous mycobacteria (NTM) have been more frequently isolated in respiratory system specimens, which were confused with MTB. We investigated whether the incidence of NTM isolation is increasing in Jeju, Korea. METHODS: The results of microbacterial cultures of acid fast bacilli (AFB) from respiratory system specimens were collected at Jeju National University Hospital, Jeju, Korea from 2004 to 2011. The incidences of MTN or NTM isolation were analyzed. RESULTS: A total of 15,484 AFB cultures were performed in 6,281 patients. In 2004, 365 AFB cultures were requested, and the number increased to 1,550 in 2011. However, the culture-positive rate decreased from 18.7% in 2004 to 6.19% in 2011. Among the 573 cultured specimens, 506 MTB (88.3%, mean age of 49.7, male 63.2%) and 72 NTM (12.6%, mean age of 65.8, male 50.0%) were identified. The proportions of NTM isolations were less than 10% until 2009, but increased to 30% after 2010 (P<0.001). M. avium complex (MAC) was the most frequently isolated NTM, followed by M. abscessus. CONCLUSION: The proportion of NTM isolation is increasing. A clinical diagnosis of pulmonary tuberculosis based on respiratory system specimens should be made with caution, especially in cases of positive AFB smears.
