Background: Thyroid cancers are rare in childhood. ATA guideline (Pediatric section) has been applied in daily practice since 2015. It is very significant to accurately predict the risk in the management of differentiated thyroid cancer(DTC). For this purpose, we shared our single center-20-year-experience about the follow-up features and management of childhood and adolescent thyroid cancer. We aimed to evaluate the dynamic risk stratification (DRS) and the o...

Abnormal DNA methylation contributes to tumor progression and is emerging as a prognostic marker in several types of cancers. To investigate whether DNA methylation is associated with pediatric adrenocortical tumor (pACT) presentation and patient prognosis, we analyzed the methylation profile of 57 tumors (MethylationEPIC BeadChip Array-Illumina) and patients’ clinicopathological features and outcome. The study comprehended 40 girls and 17 boys, with median age at diagnos...

The congenital central hypothyroidism (CCH) incidence is estimated at 1:18,000-30,000 neonates and most are included in multiple pituitary deficiencies (MPD). Clinical depend on the etiology, the deficit severity; other associated hormonal alterations and the age of diagnosis. Neonatal screening (NS) for congenital hypothyroidism that includes T4 facilitate its diagnosis.Objetives: •To evaluate the characteristics of patients with C...

Background: The aetiology of congenital hypopituitarism (CH) is unknown in the majority of patients. In our cohort of 200 cases, it was possible to establish the genetic cause in only 13 patients (6.5%). Copy number variants (CNVs) have been implicated as the cause of genetic syndromes with previously unknown aetiology.Objective: To study the presence of CNVs and its relevance in patients with CH of unknown cause associated with complex phenotypes.<p...

Background: Seip-Berardinelli syndrome is a rare form of congenital lipodystrophy.Objective and hypothesis: To report a patient later diagnosed with Seip-Berardinelli syndrome referred initially for evaluation due to low weight gain.Population and/or methods: We performed the report of the case along with a literature review.Results: The patient was referred due to low weight gain. She was the second daughter...

Background: Deficiency of one or more pituitary hormones, often with growth hormone (GH) deficiency, is defined as multiple pituitary hormone deficiencies (MPHD) or congenital hypopituitarism (CH). CH cases are mostly sporadic and have a prevalence of 1/3000-4000 live births. There are many known and yet unknown molecular pathways explaining the complex structure and functions of the pituitary gland. Many different gross and small sequence variants in the gene...

Background: Attention-deficit/hyperactivity disorder (ADHD) is the most common neurobehavioral disorder of childhood. Type 1 diabetes (T1DM) is the most common metabolic disease in children. The treatment of T1DM requires high executive functions and requires very intensive treatment that could be an obstacle for patients with ADHD. Dual diagnosis of T1DM and ADHD might affect treatment, control and complications of T1DM. In order to prevent long-term complica...

Objectives: Forkhead box A2 (Foxa2) is a transcription factor that plays a key role in foregut, pancreatic and central nervous system development. Here, we describe a 7 years old boy whose phenotype is consistent with FOXA2 defect.Case: A 3 months old boy was referred for recurrent hypoglycemic events. He was born to unrelated parents at term with a birth weight of 3690 gr. At 6 hours of life he had severe hypoglycemia (...

Background: Aromatase excess syndrome (AEXS) (OMIM 139300) is a rare condition characterized with gynecomastia in boys and macromastia in girls. Estrogen excess in boys can lead to prepubertal and pubertal gynecomastia, bone age progression and short adult stature. While most of girls are usually asymptomatic, there are few reported female patients with excessive breast growth, early puberty, menstrual irregularities, and short adult stature. Male and female children with AEXS...
