Background: Calculation of a urinary steroid metabolite ratio (uSMR) may be a useful method of improving diagnostic yield when investigating disorders of steroid hormone synthesis. Our aim was to investigate the range of uSMR in children with suspected disorders of steroid hormone synthesis.Methods: Ten ratios were calculated on steroid metabolite data analysed by GC-MS in urine samples collected between 2008 and 2010 from 94 children who were undergoing...

Background: A variable prevalence of scoliosis has been reported in Prader–Willi syndrome (PWS). Clinical detection can be challenging. The role of GH therapy (GHT) in the onset and progression of scoliosis remains controversial as does the modality of screening.Objective and hypotheses: To define the prevalence of scoliosis in our PWS patients and analyse the role of age, gender, genotype, BMI, and GHT on its onset and severity.<p class="abstex...

Aim: There is a current lack of international guidelines for managing the endocrine aspects of Noonan syndrome (NS). A clinical practice survey was developed to identify knowledge gaps and differences in the management of patients with NS across Europe.Materials and Methods: A 60-question clinical practice survey was developed for clinical geneticists, paediatric endocrinologists and paediatric cardiologists directly involved in treating...

Introduction: Prader-Willi Syndrome (PWS) is a complex genetic condition associated with feeding difficulties, hypotonia, developmental delay in infancy; hyperphagia leading to extreme obesity, growth failure and behavioral problems in childhood. Coeliac disease (CD), is an autoimmune disease characterized by gluten intolerance and a variety of symptoms most commonly diarrhea or constipation and failure to thrive. In PWS the challenge is to optimize growth while avoiding obesi...

Background: Anti-Müllerian hormone (AMH) inhibits the in utero growth of the Müllerian structures in female fetuses. In neonates with suspected disorders of sexual development (DSDs), the presence of testicular tissues and functioning Sertoli cells can be investigated by testing for serum AMH concentration.Objective: To evaluate the performance of two new AMH assays in a hospital laboratory.Method: The technical performan...

Background: Patients with 46, XY DSD present conflicts and issues related to gender identity (GI) and change to male social sex in patients registered in the female social sex is not rare. The HTP test is a projective psychological test, which assesses aspects related to sexual identification. GI in this test is defined as female (F), male (M) or ambiguous.Objective and hypotheses: To evaluate GI in patients with 46, XY DSD by the HTP test and compare th...

Background: Anti-Müllerian hormone (AMH) is produced by small growing ovarian follicles. It inhibits both FSH induced maturation of follicles as well as aromatase activity. Genetic variation of AMH signalling is associated with age at menopause and circulating oestradiol levels, i.e. AMH rs10407022 T>G (intragenic) and AMHR2 rs11170547 C>T (putative enhancer).Objective and hypotheses: This present study aims to investigate ...

Introduction: The survival rates for childhood cancer have significantly increased over the past decades but the management of treatment-related complications remains challenging. Thus, the introduction of novel drugs requires careful investigation of potential off-target side effects. The developing skeleton is severely affected by the anticancer treatment which may result in growth retardation and short stature. Venetoclax is a selective Bcl-2 inhibitor whic...

Background: The actual Swedish growth references are based on a cohort born 1974.Objective and hypotheses: Due to secular changes there is need for new height references.Method: Material: Height measurements from birth to adult height (AH) in a cohort of healthy, Nordic and born full term 1990, 20.796 from 1647 boys, 19.202 from 1501 girls were used (ALL) and compared to both a subgroup with puberty close to mean (PHV &#17...

Objectives: Diazoxide is first line treatment for hypoglycaemia due to hyperinsulinaemic hypoglycaemia (HH). However, the FDA has raised serious concerns regarding diazoxide-induced pulmonary hypertension (PH) in 2015. Although sporadic cases of PH have been reported, no HH cohort has been systematically characterised to understand severity and risk factors for diazoxide-induced PH.Methods: To investigate the onset, progress and associated factors in PH,...
