Background: In X-linked hypophosphatemia (XLH), abnormally elevated serum fibroblast growth factor 23 (FGF23) results in low renal maximum threshold for phosphate reabsorption (TmP/GFR), low serum phosphorus (Pi), inappropriately normal 1,25-dihydroxyvitamin D (1,25(OH)2D) and development of rachitic deformities.Methods: Up to four s.c. KRN23 doses were given every 28 days to 28 adults with XLH according to a dose-escalation algorithm (0.05&#1...

Background: In X-linked Hypophosphatemia (XLH), abnormally elevated serum Fibroblast Growth Factor 23 (FGF23) results in low renal maximum threshold for phosphate reabsorption (TmP/GFR), low serum phosphorus (Pi), inappropriately normal 1,25-dihydroxyvitamin D (1,25(OH)2D) and development of rachitic deformities.Methods: Up to four SC KRN23 doses were given every 28 days to 28 adults with XLH (26 completed) according to a dose-escalation algorithm (0.05&...

Objectives: In X-linked hypophosphatemia (XLH), abnormally elevated serum Fibroblast growth Factor 23 (FGF23) results in low renal maximum threshold for phosphate reabsorption, low serum phosphorus, inappropriately normal 1,25-dihydroxyvitamin D, and development of rachitic deformities. The effect of KRN23 on health-related quality of life (HRQL) was assessed.Methods: Open-label KRN23 was given s.c. every 28 days up to four doses to 28 adults with XLH (2...

Background: Congenital adrenal hyperplasia (CAH) is characterised by elevated adrenal androgens which can lead to virilisation of affected females.Objective and hypotheses: To outline clinical opinion on two controversial aspects of CAH management (antenatal dexamethasone and genital surgery of affected females) which was hypothesised would differ between regional centres.Methods: A survey was conducted via the Aus...

Background: Common metabolic diseases, including diabetes and obesity, are the result of interactions between genes and environment. It is well-recognized that the maternal intrauterine environment is an important modifier of this risk. Thus, fetuses carried by women who are obese, diabetic or suffer from suboptimal nutrition are at increased risk of insulin resistance, obesity, type 2 diabetes (T2D), and cardiovascular disease as adults. Emerging data indicate that paternal e...

Real-world studies reporting the impact of continuous glucose monitoring (CGM) in children with Type 1 diabetes (T1D) are limited. In April 2017 CGM became fully subsidised in Australia for children with T1D <21yrs. We report the impact of this in a large population based sample of paediatric diabetes (n=1093). Almost all (99%) children (age < 18yr) with diabetes in Western Australia attend a single paediatric diabetes centre.Pri...

Many factors contribute to the glycemic control in pediatric patients with type 1 diabetes mellitus (T1DM). The purpose of this IRB approved study was to determine if there was a significant correlation between the ability of pediatric patients with TiDM to accurately recognize and count carbohydrates and their hemoglobin A1C (HgbA1C). T1DM patients aged 12-17 years completed the Koontz PedCarbQuiz (PCQ) . Demographic and clinical data was extracted from the electronic health ...

Background: The effect of bisphosphonates in patients with severe osteopenia of prematurity is unknown in terms of either fracture prevention or long-term safety. A 6-month-old male infant born at 24+2 weeks gestation was referred for consideration of bisphosphonate therapy in the management of severe osteopenia of prematurity. The neonatal course included chronic lung disease requiring four courses of corticosteroids. Despite optimal calcium, phosphate and vitamin D supplemen...

Background: Beckwith-Wiedemann syndrome (BWS) characterised by a group of clinical abnormalities (macrosomia, macroglossia, neonatal hypoglycaemia, omphalocoele and umbilical hernia) results from dysregulation of imprinted genes due to mosaic paternal uniparental isodisomy (patUPD) of 11p15.5. Its association with tumours of embryonic origin is well documented and screening guidelines largely aim to detect hepatoblastoma and Wilm’s tumours during the first decade of life....

Background: Antithyroid drugs such as carbimazole form the mainstay of medical management of hyperthyroidism in children. Parents are always warned about agranulocytosis, which is a rare side effect of these drugs. Development of arthralgia after starting antithyroid medication can be a disabling side effect and needs to be distinguished from the more serious antineutrophil cytoplasmic antibody (ANCA) positive vasculitis.Objective and hypotheses: Here we...
