Thyroid nodules in children are less common than adults. However, pediatric thyroid nodules have higher rate of malignancy compared with adults, and also have increased risk of metastasis and recurrence. In this study, we analyzed clinical features, laboratory findings, and thyroid ultrasound (US) of children with thyroid nodules to determine predictive factors of thyroid cancer. Total 268 patients under 18 years of age with thyroid nodule whom visited Severance Children’...

Background: Rathke’s cleft cyst (RCC) is a benign, sellar or suprasellar lesion arising from the remnants of Rathke’s pouch that have failed to disappear in the normal development of the embryo. Patients with RCCs are mostly asymptomatic but can also exhibit various symptoms related to pituitary insufficiency. With increasing interest on endocrinology disorders of children or adolescents, the prevalence of RCCs is also on the rise. However, the studies on children or...

Objectives: We aimed to develop a non-invasive model for the detection of metabolic syndrome (MetS) in school children and adolescents.Methods: Participants were 7,330 children and adolescents aged 10–18 years attending schools in eight Chinese cities. Participants had anthropometry measured by research nurses and underwent fasting blood tests. MetS was defined as central obesity (waist-to-height ratio ≥0.46 f...

Central precocious puberty (CPP) is one of the most common pediatric endocrine diseases with an ever increasing incidence. CPP is associated with the loss of final adult height, early menarche, psychological problems and an increased risk of developing diseases in later adulthood such as female reproductive system tumors. The gonadotropin-releasing hormone stimulation test (GnRHST) is the gold standard for the diagnosis of CPP. However, the test is costly and time consuming to...

Background: The gold standard for CPP diagnosis is gonadotropin releasing hormone stimulation test (GnRHST). However, this test is expensive, invasive and inconvenient for screening. Some recent studies have demonstrated that the FMV urinary luteinizing hormone (U-LH) has a strong correlation with LH peak value and serum basal LH, and a high consistency with Tanner staging results, but due to the lack of large-sample, multicenter clinical research data, a form...

Introduction: Post-marketing surveillance registries provided extensive information about the safety and efficacy of daily growth hormone (GH) therapy during treatment. With the availability of novel long-acting GH (LAGH) therapies, it is important to determine whether the novel molecules or the different pattern of GH exposure lead to changes in the efficacy and safety profile. Therefore, new surveillance registries of LAGH are warranted.<p class="abstext...

Background: Hematopoietic stem cell transplantation (HSCT) recipients are at risk of endocrine complications as a result of chemotherapy and radiation therapy. Development of diabetes mellitus (DM) after HSCT is less frequently reported compared with other complications.Objective and hypotheses: We investigated clinical features of newly diagnosed DM after HSCT for treatment of childhood leukemia.Method: Between April 1999 and Marc...

Purpose: This study aimed to analyze growth patterns during the first two years after birth according to the birth weight and length percentile in children born preterm, and to investigate factors affecting postnatal growth of these children.Methods: Eighty-two preterm neonates with a gestational age below 37 weeks who followed up until 24 months of corrected age (CA) were retrospectively reviewed. Length, weight and hea...

Objective: To analyze the genetic cause of congenital hypothyroidism by targeted exome sequencing in pediatric patients with congenital hypothyroidism with thyroid gland in situ.Patient and Method: The study population comprised 20 patients with thyroid gland, who were diagnosed with congenital hypothyroidism at Pediatric Endocrinologic Clinic of Pusan National University Hospital. Targeted exome sequencing was ...

Objective: Ketosis-prone diabetes (KPD), characterized by presentation with diabetic ketoacidosis (DKA) in patients lacking the typical features of autoimmune type 1 diabetes, is a heterogeneous syndrome. The objective of this study is to ascertain the presence of A-β+ (autoantibody-negative, β-cell functional reserve) KPD in Korean children and adolescents and to study their characteristics in this group. Method: Diabetes ...
