, Jaehyun Kim Endocrine causes of pediatric hypertension are relatively rare but important because of their distinct treatment options. Adrenal diseases accompanied by an excess of mineralocorticoids, glucocorticoids, and catecholamines are major causes of endocrine hypertension. Typical causes of mineralocorticoid-related hypertension include primary aldosteronism, congenital adrenal hyperplasia (11β- and 17α-hydroxylase deficiencies), and apparent mineralocorticoid excess. Cushing syndrome and pheochromocytoma/paraganglioma are the primary causes of glucocorticoid- and catecholamine-related hypertension, respectively. This review provides an overview of the diagnostic evaluations, including hormonal assays and imaging studies, used to identify the underlying causes of pediatric endocrine hypertension, focusing on adrenal disorders. It presents details regarding the major adrenal disorders and recommended therapeutic approaches, emphasizing the importance of early detection and disease-specific management to prevent cardiovascular and metabolic complications in affected children.

Metabolic syndrome (MetS) is a cluster of metabolic abnormalities that include hypertension, altered glucose metabolism, dyslipidemia, and abdominal obesity and is strongly associated with an increased risk for diabetes and cardiovascular disease onset in obese adults and children. A progressively greater number of children and adolescents are being affected by this syndrome due to the constant increase in the prevalence of obesity. Like obesity, childhood MetS highly tracks to adulthood. The pathogenesis of MetS includes the interaction between obesity, insulin resistance, and inflammation. Early diagnosis and intervention are important in order to conduct lifestyle modification. In this article, we review the definition and pathophysiology of MetS, the importance of screening, and prevention and treatment options for MetS in childhood.

, Han Wool Kim, Soyoung Lee, Kyung Ha Ryu, Hae Soon Kim, Eun Sun Yoo, Hee Jung Choi, Kyung-Hyo Kim Kikuchi-Fujimoto disease (KFD) is characterized by lymphadenopathy and fever, and is usually self-limited. This study analyzed the clinical characteristics of pediatric patients with KFD.
This retrospective, observational, single-center study was conducted in South Korea from March 2008 to October 2015. KFD was diagnosed based on clinical, radiological or histological findings and excluded when there were any other causes of lymphadenopathy. Medical records were reviewed for clinical and laboratory manifestations.
A total of 35 cases were included. The mean patient age was 12.1±2.9 years (range, 5 to 17 years); the male-to-female ratio was 1:0.8. The main clinical manifestations were cervical lymphadenopathy and fever in 34 cases (97%). The mean duration of fever was 12.2±8.3 days (range, 2 to 37 days). We noted enlargement of lymph nodes in the cervical, mesenteric (n=5, 14%), axillary (n=2, 6%), and inguinal (n=1, 3%) regions. Hepatosplenomegaly, loss of appetite, and rash were observed. On laboratory examinations, elevation of ferritin, leukopenia, and positivity for anti-nuclear antibodies were frequently observed. Twelve patients underwent biopsy and 23 cases were diagnosed by radiological findings. The mean duration of hospitalization for all cases was 7.9±2.9 days (range, 3 to 13 days) and steroids were administered in 10 cases. KFD recurrence was observed in 2 cases (5.7%) with the time to relapse of 7 months and 4 years. There were no cases with systemic lupus erythematous or other autoimmune disease.
KFD should be considered in pediatric patients with lymphadenopathy and prolonged fever. Patients with KFD should be monitored for recurrence and the development of autoimmune disease.
