Increased Rates of Infantile Hypercalcaemia Following Guidelines for Antenatal Vitamin D3 Supplementation

Amato Lisa A , Neville Kristen A , Hameed Shihab , Quek Wei Shern , Verge Charles F , Woodhead Helen J , White Chris P , Horvath Andrea Rita , Walker Jan L

Background: Consultations for infantile hypercalcaemia have increased at Sydney ChildrenÂ’s Hospital since guidelines for vitamin D3 supplementation during pregnancy were introduced in 2006. Recent nationwide shortages of low-calcium formula (LCF) suggest this problem may be widespread.Aim: To determine if infantile hypercalcaemia is occurring more commonly, identify potential aetiologies and clinical significance.Me...

Absence of GH Signaling Induces Hypothalamic Inflammation that is Reversed in Response to a High Fat Diet

Baquedano Eva , Ruiz-Lopez Ana , Pardo-Barquin Elena , Gosney Elahu S , Herpy James , Chowen Julie A , Argente Jesus , Kopchick John J , Frago Laura M

Background: The GH/IGF1 axis has important roles in growth, metabolism, lipid profile and body composition. GH receptor disrupted mice (GHRKO mice) are resistant to the action of GH, thereby, GHRKO mice are dwarf, hypoinsulinemic, hypoglycemic and obese. Consumption of a high fat diet (HFD) induces inflammatory processes in a multitude of peripheral tissues, including hypothalamus.Objective and hypotheses: Our aim was to evaluate the effect of HFD intake...

Characterisation of Mutations in the Androgen Receptor Identified in 38 Brazilian Families with Complete or Partial Androgen Insensitivity Syndrome

Batista Rafael Loch , Santi Andreza , Arnhold Ivo J P , Cunha Flavia S , Costa Elaine M F , Mendonca Berenince B , Domenice Sorahia

Background: Androgen insensitivity syndrome (AIS) is a genetic disease X-linked, caused by functional abnormalities of the androgen receptor (AR). Mutations in the AR are associated with broad phenotypic spectrum from partial insensibility (PAIS) to complete insensitivity (CAIS).Objective and hypotheses: To characterize the mutations (MUT) identified in the AR in 38 Brazilian families with AIS. The MUT were analyzed considering their type, location in th...

GH Deficiency with Advanced Bone Age: GHRH Receptor Mutation Detected by Exome Sequencing Associated to Non-Classical Congenital Adrenal Hyperplasia (CAH)

Correa Fernanda de Azevedo , Franca Marcela M , Fang Qing , Ma Qianyi , Bachega Tania A , Mendonca Berenice B , LJorge Alexander , Carvalho Luciani R , Camper Sally A , Arnhold Ivo J P

Background: Isolated Growth Hormone Deficiency (IGHD) is usually associated with a delayed bone age. A genetic cause for IGHD is more frequently found in patients with familial cases and/or consanguineous parents.Objective and hypotheses: To diagnose the genetic cause of IGHD and clarify the unusual clinical presentation of advanced bone age in one patient born to consanguineous parents.Method: Sanger sequencing of GH1, <e...

Use of Aids, Assistive Devices and Adaptations (AADAs) by Individuals Aged <25 Years with Fibrodysplasia Ossificans Progressiva (FOP): 36-Month Results from a Global Natural History Study (NHS)

Hsiao Edward C. , Pignolo Robert J. , Baujat Genevieve , Brown Matthew A. , De Cunto Carmen , Keen Richard , Mukaddam Mona Al , Marino Rose , Houchard Aude , Kaplan Frederick S. ,

Background: Individuals with the ultra-rare genetic disorder FOP experience progressive heterotopic ossification. Median age at diagnosis is 5 years; patients are supported by multiple specialties. Most patients become immobilised by the third decade of life, requiring lifelong assistance. We characterise AADA use as an indicator of disease severity in younger individuals with FOP enrolled in a 36-month, prospective, global NHS (NCT02322255).<p class="abst...

A Global Natural History Study (NHS) of Fibrodysplasia Ossificans Progressiva (FOP): Normal Long Bone Growth and Abnormalities in Younger Patients over 36 Months

Pignolo Robert J. , Baujat Genevieve , Brown Matthew A. , Cunto Carmen De , Hsiao Edward C. , Keen Richard , Mukaddam Mona Al , Marino Rose , Houchard Aude , Kaplan Frederick S. ,

Background: FOP is an ultra-rare, severely disabling genetic disorder characterised by progressive heterotopic ossification. The median age at diagnosis is 5 years and patients are supported by multiple specialties. We describe normal long bone growth changes and incidence of bone abnormalities in participants with FOP aged <18 years in a 3-year, prospective, global NHS (NCT02322255).Methods: Individuals with FOP age...

Complications after pediatric thyroidectomy: lymph node dissection is a risk factor for permanent hypocalcemia

van Rooijen Jesse J. , Paul van Trotsenburg A.S. , Zwaveling-Soonawala Nitash , Nieveen van Dijkum Els J.M. , Engelsman Anton F. , Derikx Joep P.M. , Mooij Christiaan F.

Background: Thyroidectomy is a definitive treatment option in some benign thyroid disorders and the definitive treatment option for thyroid cancer. As postoperative mortality is extremely rare data on postoperative complications and long-term health consequences are important.Objective: To evaluate the frequencies of short- and long-term complications, and their risk factors in pediatric patients (0-18 years) who underwent a thyroidectomy in a tertiary c...

A prospective study of children 0-8 years with congenital adrenal hyperplasia and adrenal insufficiency on treatment with hydrocortisone granules monitored by 17-OHP saliva sampling

Neumann Uta , Braune Katarina , Whitaker Martin J , Wiegand Susanna , Krude Heiko , Porter John , Digweed Dena , Voet Bernard , Ross Richard , Blankenstein Oliver ,

Context: Children with congenital adrenal hyperplasia (CAH) and adrenal insufficiency (AI) require hydrocortisone replacement from birth. Continuous monitoring of therapy during growth is necessary. Until now, children were dependent on off label use with divided hydrocortisone tablets or pharmacy compounded capsules. A licensed paediatric formulation that allows accurate dosing down to 0.5mg is now available.Objective: ...
