Background/Aim: X-linked hypophosphatemia (XLH) is a rare disease caused by mutations in PHEX, leading to elevated FGF23 levels, hypophosphatemia and chronic renal phosphate wasting. Burosumab is a monoclonal antibody against anti-FGF23, which has been recently approved for treatment of XLH. Beyond clinical trials, little is known about its efficacy/safety in clinical practice which is the aim of study.Patients/Methods: ...

Background/Aim: X-linked hypophosphatemia (XLH) is a rare disease caused by inactivating mutations in the phosphate-regulating endopeptidase homolog X-linked (PHEX) gene, characterized by chronic hypophosphatemia. XLH children present with progressive skeletal deformities (leg bowing, waddling gait, poor growth and disproportional short stature), dental abscesses, and craniosynostosis. Most affected children have been treated so far with multiple dail...

An Unusual Case of Hypophosphatemia in a Child Affected by Di George Syndrome

Kalapurackal Mila Ann , Barzaghi Federica , Pitea Marco , Cassano Gilda , Weber Giovanna

A female child born from non consanguineous parents of Pakistani origin presented with congenital heart anomaly at prenatal ultrasound and confirmed at birth, with type B aortic arch interruption, right-sided aortic arch, wide ventricular and atrium septum defects, which required repeated surgical corrections during the first 9 months of life. The ultrasound also reported absence of the thymus. Suspecting Di Deorge Syndrome, a fluorescent in situ hybridization (FISH) ...

Thyrotoxic Periodic Paralysis, an Under-Recognized Condition

Nip Siu Ying , Di Blasi Carolina

Background: Thyrotoxic periodic paralysis (TPP) is a rare clinical manifestation of hyperthyroidism, commonly seen in Asian males. Patients often present with sudden onset muscle weakness associated with severe hypokalemia.Case presentation: A 16-year-old Filipino male presented with acute onset bilateral lower extremities weakness. He woke up at night but was unable to move his legs. He denied any recent viral infections, ingestion of canned food or his...

Unusual Differential Diagnosis of Hyperandrogenism in Adolescent Female Treated for Polycystic Ovarian Syndrome

Blasi Carolina Di , Amies-Oelschlager Anne-Marie , Ness Kathryn , Giesel Ann

Background: Polycystic ovarian syndrome (PCOS) is the most common cause of oligomenorrhea and hyperandrogenism. Diagnostic criteria for PCOS includes ovarian dysfunction and clinical or biochemical evidence of hyperandrogenism. The differential diagnosis includes congenital adrenal hyperplasia as well as steroid producing tumors.Case presentation: 18-years-old female presented to establish care with a history of PCOS diagnosed at the age of 11 years. She...

Project to improve paediatric post-neurosurgical fluid management and to reduce the risks associated with Diabetes Insipidus (DI), Syndrome of Inappropriate ADH (SIADH) and Cerebral Salt Wasting (CSW).

Miller-Molloy Felix , Saxena Shreya , Bowen Philippa , Fellows Greg , Crowne Liz

Background: Complex fluid balance problems are well established post-neurosurgery and traumatic brain injury (TBI). The triple-phase response requires fluid management strategies reactive to urine output as patients shift between DI and SIADH. Prevalence of CSW is controversial; but ensuring sodium homeostasis is central to safe fluid management. To improve clinical care for these complex patients an audit of existing institutional guidelines was undertaken. N...

Background: Children with familial forms of central diabetes insipidus (CDI) display polyuria and polydipsia within the first years of life.Objective and hypotheses: We hypothesize that children with an early-onset idiopathic CDI might be affected by de novo genetic mutations.Method: Eleven children aged between 1 month and 7 years with polyuria and polydipsia and negative family history were enrolled. In nine of them with...
