Background: Von Hippel-Lindau (VHL) syndrome is a rare autosomal dominant genetic disorder characterized by retinal and central nervous system hemangioblastomas, pheochromocytomas and multiple cysts in the pancreas and kidneys, with increased risk of malignant degeneration.Case presentation: A 9-year-old boy with uncomplicated premorbid and family history presented with ice-cold hands and profuse night sweating on the he...

Background: Subjects born small for gestational age (SGA) were shown to be at higher risk for metabolic consequences in adulthood but less is known on their cardiovascular function.Objective and Hypotheses: We aimed to investigate cardiovascular function and left ventricular mass index (LVMI) in adolescents born SGA and appropriate for gestational age (AGA) and their relationship with perinatal and postnatal factors....

Background: The prevalence of MODY2 in the gestational diabetic population has been estimated to be approximately 2%. Risk of macrosomia in GCK/GDM cases depends on maternal glycemic control and fetal mutation status. However, the fetal genotype is unknown before birth. We assessed the effects of insulin therapy on the birth weight of children born to mothers with GCK mutations.Objective and hypotheses: The study included 38 patients with GDM due to GCK ...

Introduction: Neonatal diabetes mellitus (NDM) is a rare form of insulin-dependent monogenic diabetes mellitus (1/400,000 live births) diagnosed in the first six months of life. It can be either transient or permanent, with abnormalities in the parental chromosome 6q24 and with mutations in genes related to the ATP-sensitive potassium pump in the β-cell membrane respectively.Aim: We describe a male infant, 2.5 months old, diagnosed with NDM and panc...

Background: Progestins such as lynestrenol (L) can be used in female to male (FtM) adolescents with gender dysphoria (GD) who have advanced pubertal development to reduce the psychological burden of menstruation. L can later be combined with cross-sex hormones (testosterone esters) (L+T). L is much cheaper and easier to administer than GnRHa. To date, few data exist on the (side) effects of progestins for this indication.Objective and hypotheses: To repo...

Background: Male to female (MtF) gender dysphoric adolescents with advanced pubertal development can be treated with antiandrogenic progestins such as cyproterone acetate (CA). CA is much cheaper and easier to administer than GnRHa and can later be combined with cross-sex hormones (17β-estradiol) (CA+E). To date, few data exist on the (side) effects of progestins for this indication.Objective and hypotheses: To report the effects of consecutive CA a...

Background: 46XY DSD with female phenotype is classified as complete gonadal dysgenesis (46XY CGD) if a uterus is present or a disorder of androgen synthesis or action if a uterus is absent. The genetic causes of 46XY CGD are not fully clarified. Less than 15% of the cases were found to carry mutations of the sex determining region Y gene (SRY).Purpose: The description of the rare case of two sisters affected of 46XY CPD and gonadoblastoma with SRY mutat...

Aim: To present some therapeutic difficulties in patients with congenital generalized lipodystrophy (CGL) - a rare autosome recessive disorder characterized by complete absence of adipose tissue. For many years therapy was aimed only at metabolic consequences. In the past few years new pathophysiologic treatment has become available.Methods and materials: We present four girls – currently 25, 22, 16 and 15 years ol...

Background: In gender dysphoric (GD) adolescents with advanced pubertal development, psychological relief can be attained with progestins, which are much cheaper and easier to administer than GnRHa. Moreover, use of GnRHa has been shown to interfere with pubertal bone mass accrual. To date, few data exist on the effects of progestins on body composition (BC) and bone parameters in this population.Objective and hypotheses: To explore the effects of pro- a...

Background: Several studies in adults have provided evidence for opioid-induced hypofunction of the hypothalamo-pituitary–adrenal and GH–IGF1 axis after chronic (oral and intrathecal) administration. This so-called opioid endocrinopathy has not been reported in children.Objective and hypotheses: We report the occurrence of delayed growth with low serum IGF1 levels and recurrent hypoglycemia due to central hypocorticism in a toddler after a pres...
