Objective: to assess diagnostic usefulness and accuracy of different tools in patients with Kallmann syndrome and ichthyosis due to X-chromosome microdeletion.Materials: сongenital hypogonadotropic hypogonadism due to KAL1 pathological variants manifest with micropenis, cryptorchidism, delay of puberty, and not associated with disorder of sex development. This condition can be associated with ichthyosis due to deletion of X chromosome region with genes KAL...

We report on a nearly 4-year-old girl who presented to the emergency room of our paediatric clinic with high fever and poor general condition, swelling of the neck and swallowing difficulties. Laboratory chemistry showed a marked hyperthyroid metabolic state, so that initially a thyrotoxic crisis in Graves' disease was considered (TSH 0.03 mU/L (-), fT4 28.10 pmol/l (+)). Therefore, a short-term therapy with thiamazole was given. The thyroid autoantibodies were negative. ...

Background: Hypophosphatemic rickets (HR) comprises a group of inherited forms of rickets characterised by renal phosphate wasting. Taking info account the latest advances in HR therapy, it now becomes of interest to better define the mutational and phenotypic spectra of disease.Objective and Hypotheses: The aim of this study was to clinically characterize and perform genetic analysis of 168 cases with HR.<p class="a...

Aim: Western Australia is a state with unique geography and population distribution having only a single tertiary paediatric hospital (Princess Margaret Hospital, PMH in Perth) managing the majority of children and adolescents with fractures in the Emergency Department (ED). Fracture incidence in 0–16 year olds is known to be high and varies between countries with boys having a 1.5 fold higher fracture incidence than girls. There are no specific data for Australia. The ai...

It is generally accepted that androgens produced by fetal Leydig cells (FLC) control proper masculinization of the male external genitalia. Here, we hypothesized that the human genital tubercle (GT) has potential to synthesize androgens independently of FLC at early pregnancy. We observed that human GT of both genders have capacity to synthesize steroids of the Δ4, Δ5 and alternative pathway of DHT synthesis including the androgen itself. The presence of steroids in ...

Background: Hypophosphatemic rickets (HR) comprises a group of inherited forms of rickets characterised by renal phosphate wasting. To date more than 10 genes are associated with HR, and a comprehensive molecular diagnosis in these disorders is technically difficult to perform.Objective and hypotheses: To assess the value of targeted next-generation sequencing (NGS) used for molecular analysis of candidate genes of HR.Method: 64 pa...

Background: Autoimmune polyglandular syndrome type 1 (APS-1) is &acy; rare multisystem disorder due to mutations in the autoimmune regulator gene (AIRE). APS-1 usually is characterized by a triad of hypoparathyroidism, primary adrenal insufficiency (PAI) and chronic mucocutaneous candidiasis. In the absence of the classic triad, the diagnosis becomes obscure and is often delayed.Case presentation: We report a 12 years ol...

Introduction: Noonan syndrome-Neurofibromatosis type 1 (NSNF) is a genetic disorder characterized with clinical features of both Noonan syndrome (NS) and neurofibromatosis type 1 (NF1). Recombinant human growth hormone (rhGH) has been widely used in NS patients as well as in some patients with NF1 but there are only a few published cases of rhGH treated NSNF patients. We report a patient with NSNF with short stature who started rhGH treatment with subsequent p...

Background: Bardet-Biedl syndrome (BBS) causes early-onset extreme obesity and hyperphagia that is hypothesized to arise from leptin receptor dysfunction. Setmelanotide, a melanocortin-4 receptor (MC4R) peptide agonist, has been shown to induce weight loss in individuals affected by other rare genetic obesity disorders resulting from leptin-melanocortin pathway dysfunction upstream of MC4R.Objective: Report preliminary data on body weight, hunger scores,...

Introduction: HbA1C goals are rarely achieved in children with Type 1 diabetes (T1D) except at the cost of increased hypoglycaemia episodes. The Diabeloop Hybrid Closed-Loop system improves time in range and glycemic control in adults. However, the efficacy and safety of the system had not yet been evaluated in children. Our objective was to evaluate the safety and efficiency of the Diabeloop hybrid closed-loop system in prepubescent children (DBL4K).<p cl...
