Background: severe primary insulin-like growth factor-1 deficiency (SPIGFD) is a rare growth disorder, for which insulin-like growth factor-1 (IGF-1) generation test (IGFGT) is debated as a complementary diagnostic analysis. Diagnostic workup for SPIGFD varies geographically and diagnosis is delayed by the rarity of the condition (<1/10,000). Evaluation of real-world practices of IGFGT could help facilitate diagnosis and test use. Objective: to describe rea...

Background/Aim: The trade-off theory claims that a resource (calorie) stored in adipose tissue cannot be used for longitudinal growth, and a calorie used for growth will not be stored as fat.Methods: Out of 2339 children with longitudinal heights and weights (birth to adulthood) from the GrowUp1990 Gothenburg cohort, 1993 (996 girls) were analyzed. For everyone we calculated Energy Trade-Off Score: ETOS = at early adulth...

Introduction: Deficiency of 17β-hydroxysteroid dehydrogenase 3 (17β-HSD3) enzyme encoded by HSD17B3 is a rare cause of disorders of sex development (DSD). The phenotype associated with 17β-HSD3 deficiency in 46, XY individuals is variable, ranging from predominantly male external genitalia with micropenis and hypospadias to completely female external genitalia. The diagnosis and management of this enzymatic defect is very challenging.<p class="abste...

Background: Premature adrenarche (PA) has been considered a benign condition. Recently, associations with increase androgen levels and PCOS have arisen.Objective: To determine whether PA in children at pubertal onset (TII) determines a different timing of pubertal events and a different pattern of ovarian and adrenal hormones.Methods: A total of 583 girls from the longitudinal cohort (Growth and Obesity Cohort Study, born 2002) wer...

Background: Premature adrenarche (PA) has been considered a benign condition. Recently, associations with an increased metabolic risk have arisen. This risk may depend on ethnic background and infancy weight gain, which could be different by gender.Objective and hypotheses: To determine whether PA in children at pubertal onset (TII) determines a higher metabolic profile.Methods: 1190 children (49.9% female) from the longitudinal co...

Context: Physiological growth hormone is secreted during the slow-wave sleep. Traditionally, growth hormone (GH) therapy is given in daily GH injections before sleep. This schedule better imitates the physiological diurnal variation of GH secretion and action. Late-night daily injections have been claimed to be associated with sleep disturbances and insomnia, yet there is no hard evidence supporting this contention. Morning and evening GH injections produce co...

Background: Childhood craniopharyngiomas are known to be associated with an increased risk of excessive weight gain and hypothalamic obesity. Atypical clinical manifestations include the development of a diencephalic syndrome (DS) with a failure to thrive or weight loss.Objective and hypotheses: In a retrospective study we analyzed 21 of 485 childhood craniopharyngioma patients (4.3%) who presented with a low weight (<−2 BMI SDS) at time of dia...

Background: Improved tools for diagnosis, a higher malignancy risk in thyroid nodules and the referral to surgery in Grave’s disease when medication fails, have lead to increased thyroidectomies in children.Objective and hypotheses: The aim of our study was to evaluate thyroid surgery outcomes and the presence of transient or permanent complications, in a cohort of children who underwent surgery, with the same surgical team, in the last 10 years.</p...

Background: Lipoprotein lipase (LPL) deficiency is an autosomal recessive disease with deficient extrahepatic removal of blood lipoproteins.Objective and hypotheses: Primary LPL deficiency can be exacerbated by coexistent conditions such as diabetes, where relative or absolute insulin deficiency leads to an additional secondary LPL deficiency.Method: We describe two cases in which primary LPL deficiency overlapped with previously d...

Background: The increase of global childhood obesity has led to an increase of associated co-morbidities also at a young age. The pro-inflammatory state and insulin resistance are two master regulators of several complications, including hypertension and pre-diabetes frequently connected in a complex crosstalk.Aim: To evaluate the relationship between glucose alterations and blood pressure and the pathogenetic involvemen...
