Cushing’s disease (CD) is rare entity especially in pediatric patients. It is associated with significant morbidity. Early diagnosis and treatment is important for optimal outcome.Aim: To evaluate the clinical, biochemical, pathology, treatments and outcome in a cohort of CD pediatrics patients in a single tertiary center.Subjects and Methods: Retrospective review of 27 medical records of CD ...

Background: GnRH-analogs (GnRHa) are the recommended treatment for Central Precocious Puberty (CPP). Despite a normal long-term outcome is generally reported, reproductive function and emotional sphere in adulthood are still poorly evaluated.Objective: To evaluate the general long-term outcome of young women with previous CPP treated with GnRHa.Patients and Methods: A cohort of 63 ...

Background: Neonatal screening strategies revealed an increase in hypothyroidism associated with an in-situ thyroid gland due to TSH receptor (TSHR) mutations. While there are many genetic and functional studies regarding TSHR mutations, few are found concerning the clinical course and long-term outcome of TSH resistance involving the pediatric population.Objective and hypotheses: To determine the impact of TSHR mutations on clinical course, biochemical ...

Background: Obese children are often taller than non-obese ones before puberty. Reports on the GH/IGF system in obese children are not consistent and do not explain the increased height observed. Changes in IGF1 bioavailability/bioactivity have been claimed as a possible explanation, however, no data is available regarding the expression of the IGF type 1 receptor (IGF1R) gene.Objective and hypotheses: To study the expression of IGF1R gene in obese child...

Introduction: Of any pituitary dysfunction following brain injury, growth hormone (GH) deficiency (GHD) is the most prevalent. The cut-point for defining GHD has been placed at 7 ng/mL representing optimum test performance. We hypothesised this cut-off may be set too low for genetically taller children with acquired brain injury, notably brain tumours, who demonstrate severe growth failure but repeatedly fail to meet diagnostic thresholds for GH replacement until several centi...

Background/Aims: 46,XY gonadal dysgenesis (GD) is classified as complete (CGD) or partial (PGD) depending on gonadal morphology and function. In contrast to the typical female external genitalia in CGD, the phenotype of PGD is variable depending on androgen production. A diagnosis of PGD is based on clinical/biochemical features, gonadal histology and genetic findings. The aim of this study is to characterise these features, particularly histological, in a lar...

Introduction: BIPSS before and after desmopressin stimulation has been shown to be a useful tool for diagnosis of ACTH-dependent CD and negative magnetic resonance imaging (MRI)or positive MRI but inconsistent biochemical data, in adult patients. However, little is known about its usefulness in pediatric population.Objective: To evaluate the prevalence of negative MRI, the sensitivity of BIPSS before and after desmopress...

Introduction: The underlying genetic causes of congenital hypothyroidism with gland in-situ (CH GIS) and hyperthyrotropinemia (HT) remain largely a mystery. Thanks to NGS, genetic screening is now finding many novel variants. The challenge is to correctly identify which genes and which variants lead to CH and which cause only a transient HT.Objectives: Our objectives were to evaluate the presence of variants in 14 candid...

Background: Growth spurt is a major event in central precocious puberty (CPP). GnRH analogue (GnRHa) therapy inhibits gonadal axis and decreases height velocity. However, serum IGF1 and IGFBP-3 remain high as before therapy. Reports on IGF type 1 receptor (IGF1R) in CPP are yet unavailable.Aim: To study IGF1R mRNA expression in girls with CPP before and during GnRHa therapy.Methods: 34 girls with CPP were studied. Sixteen of them (...

Papillary thyroid cancer (PTC) is the most common thyroid tumor in childhood and adolescence. Most of these patients are referred with locally advanced and/or distant disease at the moment of diagnosis. Whenever is possible, these patients should be offered a total thyroidectomy and radioiodine remnant ablation. However, this approach is not always possible to perform, becoming these tumors as unresectable. These critical cases could benefit from the neoadjuvant treatment with...
