OBJECTIVES: We planned to evaluate the association of fetal and maternal thyroid hormones and maternal iodine status with neonates' anthropometric parameters. METHODS: In this cross-sectional study, levels of thyrotropin were measured in maternal serum in the first trimester of pregnancy, and thyrotropin (TSH) and free thyroxin (fT4) were measured in cord blood serum samples at birth. Urinary iodine concentration (UIC) levels in random urine samples of mothers were measured in the third trimester of pregnancy...

Several aspects of clinical management of 46,XX congenital adrenal hyperplasia (CAH) remain unsettled and controversial. The North American Disorders/Differences of Sex Development (DSD) Clinician Survey investigated changes, over the last two decades, in clinical recommendations by specialists involved in the management of newborns with DSD. Members of the (Lawson Wilkins) Pediatric Endocrine Society and the Societies for Pediatric Urology participated in a web-based survey at three timepoints: 2003-2004 (T1, n = 432), 2010-2011 (T2, n = 441), and 2020 (T3, n = 272)...

OBJECTIVE: To investigate the diagnostic value of urine luteinizing hormone (ULH) after triptorelin stimulation test detected by immunochemiluminometric assay (ICMA) in girls with central precocious puberty (CPP). METHODS: The girls with precocious puberty were involved. The triptorelin stimulation test at 8:30 a.m.were performed. Two consecutive 12-hour urine samples were collected after the test, defined as first 12-hour and second 12-hour urine, respectively...

Very early onset inflammatory bowel disease (VEOIBD) is a rare entity in pediatrics. Its association with primary immunodeficiencies of monogenic origin is known. We present the case of a patient diagnosed with VEOIBD who underwent massive paralleled exome sequencing. The result of the study showed a pathogenic variant in the RET proto-oncogene, associated with multiple endocrine neoplasia type 2A disease. There are no previous reports of association of RET proto-oncogene variants with VEOIBD. The presence of these two clinical entities cannot be attributed to a single genetic cause...

Disorders of sex development (DSD) are a clinically and genetically highly heterogeneous group of congenital disorders. The most accurate and rapid diagnosis may be possible with a complementary multidisciplinary diagnostic approach, including comprehensive clinical, hormonal, and genetic investigations. Rapid and accurate diagnosis of DSD requires urgency in terms of gender selection and management of the case. Despite the genetic tests performed in current daily practice, the genetic cause is still not elucidated in a significant proportion of cases...

Delayed puberty is defined as the lack of development of secondary sex characteristics in childhood. Based on a review of the literature, delayed puberty can be divided into three main categories: (i) hypergonadotropic hypogonadism (congenital and acquired), (ii) permanent hypogonadotropic hypogonadism (congenital and acquired), and (iii) transient hypogonadotropic hypogonadism [constitutional delay of growth and puberty (CDGP) and functional hypogonadotropic hypogonadism (FHH)]. CDGP is the most common cause of hypogonadism in both males and females, accounting for 60% and 30% respectively...

OBJECTIVE: The frequency of obesity and poor sleep quality among adolescents is increasing and causes many chronic problems. The objective was to investigate the correlation between body mass index (BMI), sleep quality, sleep duration and social jet lag (SJL) among adolescents. METHODS: This study is cross-sectional. A cohort of 416 adolescents, ranging in age from 12 to 18 participated in the study. Adolescents were divided into three groups according to BMI SDS: adolescents with normal weight, adolescents with overweight and adolescents with obesity...

OBJECTIVES: Previous reports indicate that diabetic ketoacidosis (pDKA) rates in Malaysian children with type 1 diabetes range between 54-75%, which is higher than most European nations. Knowledge of trends and predictors of DKA can be helpful to inform measures to lower the rates of DKA. However, this data is lacking in Malaysian children. Hence, the aim of this study was to determine the predictors and trends of pDKA in Malaysian children at the initial diagnosis of T1DM. METHODS: This cross-sectional study examined demographic, clinical and biochemical data of all newly diagnosed Malaysian children aged 0-18 years with T1DM over 11 years from a single centre...

OBJECTIVE: Differentiated thyroid cancer (DTC) is the most common pediatric endocrine cancer but studies are scarce. Latest recommendations advocate for an individualized risk-based approach to select patients for additional therapy. Lymphovascular invasion is not considered, despite being a well-known risk factor in the adult population. The aim of our study was to describe the outcomes of a cohort of DTC patients diagnosed at pediatric age and to evaluate the impact of lymphovascular invasion on the risk of persistence/recurrence...

Thyroid nodular disease can present in different forms, such as a solitary nodule, multinodular goiter, nodular goiter caused by autoimmune goiter, and nonpalpable thyroid nodules. Among children, thyroid cancer is the most common type of endocrine cancer. Pediatric thyroid cancer is usually detected as a neck mass without any symptoms, leading to variable stages of progression when diagnosed. Papillary thyroid carcinoma is the most common type of thyroid cancer in children with thyroid nodules. We are presenting a case of an 8-year-old male child who was referred to Jimma Medical Center after he developed swelling on the right side of his neck...

Short stature in children is a common reason for referral to a pediatric endocrinologist. A myriad of genetic, nutritional, psychological, illness-related, and hormonal causes must be excluded before labeling as idiopathic. However, idiopathic short stature (ISS) is not a diagnosis, but rather describes a large, heterogeneous group of children, who are short and often growing at the lower limit of the normal range. As new testing paradigms become available, the pool of patients labeled as idiopathic will shrink, although most will still have a polygenic cause...

OBJECTIVE: The objective of this study was to explore the associations between a family history of type 2 diabetes (T2D) and beta-cell function, as well as lipid profile, in pediatric patients newly diagnosed with type 1 diabetes (T1D). METHODS: A retrospective analysis was conducted on children under 14 years of age who were newly diagnosed with T1D at the Children's Hospital of Zhejiang University between August 2018 and August 2022. Clinical features, metabolic profiles, beta-cell function, and lipid profile were evaluated...

Pain in early life may seriously impact neonatal outcomes. This study aimed to evaluate whether the perceptions of physicians working in neonatal intensive care units (NICUs) of the short-term adverse outcomes associated with neonatal pain have changed over a 20-year period. Self-administered questionnaires were distributed to 117 and 145 neonatologists, pediatricians, and fellows working in level III NICUs in 2000 (T1) and 2019 (T2), respectively. The questionnaire consisted of four domains, including the central nervous, cardiovascular, and respiratory systems, as well as "other systems" (metabolic/endocrine system, growth, and general condition), with 21 total items overall...

OBJECTIVE: Maturity-onset diabetes of the young (MODY) occurs due to mutations in genes involved in pancreatic beta cell function and insulin secretion, has heterogeneous clinical and laboratory features, and account for 1-5% of all diabetes cases. The prevalence and distribution of MODY subtypes vary between countries. The aim of this study was to evaluate the clinical and laboratory characteristics, mutation distribution, and phenotype-genotype relationship in a large case series of pediatric Turkish patients genetically diagnosed with MODY...

INTRODUCTION: Turner Syndrome is a rare condition secondary to a complete or partial loss of one X chromosome, leading to a wide spectrum of clinical manifestations. Short stature, gonadal dysgenesis, cardiovascular malformations, and dysmorphic features characterize its common clinical picture. AREAS COVERED: The main endocrine challenges in adolescent girls with Turner Syndrome are puberty induction (closely intertwined with growth) and fertility preservation...

INTRODUCTION: Craniopharyngiomas (CPG) have complex challenges in treatment due to their proximity to vital structures, surgical and radiotherapeutic complexities, and the tendency for recurrence. This study aims to identify the prevalence of endocrine and metabolic comorbidities observed during initial diagnosis and long-term follow-up in a nationwide cohort of pediatric CPG patients. The study also highlights the associated difficulties in their management. METHODS: Sixteen centers entered 152 patients into the ÇEDD NET data system...

OBJECTIVE: Non-alcoholic fatty liver disease (NAFLD) is defined as chronic hepatic steatosis and is becoming prevalent along with the increasing trend of obesity in children and adolescents. A non-invasive and reliable tool is needed to differentiate non-alcoholic steatohepatitis (NASH) from simple steatosis. This study evaluates the association between the triglyceride glucose (TyG) index and the ultrasonographic fatty liver indicator (US-FLI), and the possibility of using the TyG index for prediction of severity of pediatric NAFLD...

Teplizumab (TzieldTM, Provention Bio), a monoclonal antibody directed at t-cell marker CD3, is the first medication approved by the FDA to delay progression from Stage 2 to Stage 3 type 1 diabetes (T1D). To date, the overwhelming majority of pediatric endocrinologists do not have experience using immunotherapeutics and seek guidance the use of teplizumab in clinical practice. To address this need, the Pediatric Endocrine Society (PES) Diabetes Special Interest Group (Diabetes SIG) and Drug and Therapeutics Committee assembled a task force to review clinical trial data and solicit expert recommendations on the approach to teplizumab infusions...

OBJECTIVES: Transient hyperthyrotropinemia/transient hypothyroxinaemia and congenital hypothyroidism (CH) have completely different treatment and clinical outcomes. However, a powerful, highly sensitive and cost-effective marker for the differentiation of these clinical entities in the early postnatal period is not available. Therefore, we aimed to test the potential, early predictive, diagnostic power of the thyroid-stimulating hormone (TSH)/free thyroxine (fT4) ratio for differentiation of the two clinical entities in the early period of life...

OBJECTIVES: The most common cause of primary hyperparathyroidism (PPH) in children is a parathyroid adenoma. Among this population, PPH exhibits higher levels of morbidity, severity and target organ involvement compared to adults. When there is suspicion of PPH, cervical ultrasound and 99m Tc-sestamibi SPECT/CT are the imaging test traditionally indicated. Among adults, the use of [18 F]fluorocholine PET/CT has shown a higher sensitivity than ultrasound and [99m Tc]sestamibi SPECT/CT, leading to an expanding adoption in recent years...
