Introduction: Pubertal growth is hormone dependent. The anthropometric (height, weight) and sexual (Tanner stage (TS)) changes are accompanied by growth in foot length. However, the relationship between changes in foot length and other anthropometry remains unclear. Our aim was to determine how changes in foot length relate to growth parameters (height and weight), self-rated TS and serum sex steroids.Methods: We used data from the Adolescent Rural Cohor...

Background: Pycnodysostosis is a very rare autosomal recessive skeletal dysplasia caused by cathepsin K deficiency. It is characterized by extreme short stature resulting in an adult height in males typically <150 cm and in females <134 cm. Bone-fragility and frequent fractures are present. There are few case-reports on the effects of GH treatment.Objective: To evaluate the effect and safety of GH in 6 patients wit...

Background: Controlling therapy of infants, especially from neonates onwards, with classic congenital adrenal hyperplasia (CAH) is challenging due to the lack of reference values.Methods: We retrospectively analyzed 158 spot urinary steroid hormone metabolite profiles determined by gas chromatography–mass spectrometry (GC-MS) of 60 infants aged 0–4.2 years with classic 21-hydroxylase deficiency (21-OHD) on hydr...

The amniotic fluid (AF) milieu is complex and essential to fetal well-being. Here we present a new LC-MS/MS method for the targeted metabolomics analysis of 20 unconjugated and conjugated steroids in 65 AF samples during mid-gestation. Sample preparation included protein precipitation, centrifugation, solid phase extraction and derivatization. We measured progesterone (Prog), 17α-hydroxyprogesterone (17OHProg), testosterone (T), estrone (E1), estradiol (E2), estriol (E3),...

Background: In children with Prader–Willi Syndrome (PWS), hypothalamic dysfunction plays a key role in the development of aberrant energy regulation, sleep-related breathing disorders, hypogonadism and impaired linear growth. Dysfunction of the hypothalamic–pituitary–adrenal (HPA) axis may contribute to the high incidence of sudden death. The prevalence and the extent of the dysfunction of HPA axis remain unclear.Method: Thirty-one (10M/21...

Background: NSIAD is a rare genetic cause of hyponatremia, due to activating mutations in AVPR2 gene, encoding the Arginine Vasopressin Receptor Type 2, and located on Xq28. Of the fewer than 30 reported cases, most have been managed with fluid restriction and urea.Objective and hypotheses: Illustration of the presentation of a family with this genetic abnormality and approach to management.Method: The clinical, biochemical and gen...

Background: In 2007, the Turner syndrome (TS) Consensus Study Group developed an international guideline for clinical care of girls and women with TS. Given emerging concerns of long term cardiovascular complications, the consensus recommends that cardiac MRI should be performed when girls are old enough to tolerate the procedure or at the time of transition and to be repeated at least every 5–10 years.Method: We conducted a survey of cardiovascular...

Background: Rare congenital conditions with incongruence of chromosomal, gonadal, and phenotypic sex have been summarized as disorders of sex development (DSD). Included in DSD are conditions with diverse genetic etiology, varying levels of prenatal androgen effects, phenotypes, and subsequently, different medical treatments. Quality of life (QoL) and psychological wellbeing are indicators of successful psychosocial adaptation to the conditions. Studies addressing these issues...

Introduction: The diagnosis of a disorder/difference of sexual development (dsd) is an exceptional psychosocial situation. As the diagnosis is often made in childhood, the parents are the primary communication partners. In some cases, the impossibility of immediate sex determination of the child can be a traumatic experience with a negative impact on the relationship between the parents and the child, the couple and members of the entire family. It has been recommended by the ...

Introduction: Increased cytokine release, impaired antioxidation and reactive oxygen species (ROS) have been shown in β-cells in pathogenesis of T1DM. Increased ROS leads to formation of covalent bonds between the sulfur atoms, leading to disulphide conversion. Displacement to disulphide form of this thiol/disulphide balance starts the oxidative damage. This study evaluates the thiol/disulphide balance in children with T1DM.Material...
