Nephrocalcinosis in Children with X-Linked Hypophosphatemia: Prevalence and Risks Factors

de Truchis Camille , Zhukouskaya Volha , Auger Martin , Rothenbuhler Anya , Linglart Agnès , Grapin Mathilde

X-linked hypophosphatemia (XLH) is diagnosed in children with clinical and or radiological signs of rickets, impaired growth velocity, low serum phosphate levels associated with renal phosphate wasting, in the absence of vitamin D or calcium deficiency. Conventional treatment is made of phosphate and active vitamin D. However, nephrocalcinosis has been identified as a complication of this therapy. Its prevalence is about 25-40% in adult XLH treated patients. It was never c...

Effect of Feeding Mode on Longitudinal Body Composition in Early Life

de Fluiter Kirsten S , van Beijsterveldt Inge ALP , Acton Dennis , Hokken-Koelega Anita CS

Background: Excessive gain in fat mass (FM) during the first months of life, known as the critical window for adiposity programming, is associated with an increased risk for adiposity and cardiovascular diseases in later life. Early life nutrition (breastfeeding or formula feeding) might influence body composition (FM and fat free mass (FFM)) development in early life.Aims: To investigate differences in sex-specific long...

Intestinal Ganglioneuromatosis as First Manifestation of Multiple Endocrine Neoplasia 2B in a Premature Girl

Leunbach Tina Lund , Madsen Mette , Nielsen Rasmus G , Hansen Dorthe , Mathiesen Jes S

Introduction: Multiple endocrine neoplasia 2B (MEN2B) is a rare cancer syndrome primarily caused by the M918T (95%) and A883F (<5%) germline mutations in the REarranged during Transfection (RET) proto-oncogene. Aggressive and early onset thyroid medullary carcinoma is the hallmark of the disease. Cure rates in M918T carriers who had thyroidectomy before and after 1 year of age were 83% and 15% respectively. More t...

Bone Age Determination in Girls with Early Puberty and Limitations of Adult Height Prediction: Can Automated Evaluation (BoneXpert™)be a Solution?

Yesiltepe-Mutlu Gul , Capaci Merve , Uzunkopru Gizem , Hatun Sükrü

Introduction: One of the factors affecting the treatment decision in early puberty is bone age (BA) evaluation and adult height prediction (AHP), accordingly. These calculations have certain limitations. In this study, we aimed to compare the AHP results calculated by Bayley-Pinneau (BP) and Roche-Wainer-Thissen(RWT) methods based on BA evaluation by using Greulich-Pyle(GP) atlas and BoneXpert™ software.Methods: A t...

Complexities of Diagnosis in 17-Beta-Hydroxysteroid Dehydrogenase Deficiency and Implementation of Next Generation Sequencing in Guiding Management Decisions – Case Series of Six Patients

Taylor-Miller Tashunka , Barton John S , Burren Christine P , Woodward Mark , Alderson Julie , Crowne Elizabeth C

17-beta-hydroxysteroid dehydrogenase (17-beta-HSD3) deficiency is an autosomal recessive 46XY disorder of sex development (DSD), which results in impaired gonadal androstenedione conversion to testosterone. The phenotype ranges from female to ambiguous genitalia, with wolffian-duct structures and testes. HCG stimulation tests assess testosterone biosynthesis, though biochemical results in confirmed 17-beta-HSD3 deficiency may overlap with gonadal dysgenesis making diagnosis ch...

We analyzed the clinical data and the growth parameters of 50 newborns and young infants (age: 1.6 ± 0.9 months) admitted to our hospital (Al Wakhra Hospital, Department of Pediatrics, Doha, Qatar), between 1-1-2016 to 1-1-2017, with acute meningitis. Anthropometric measurements included weight, length, and head circumference. Length SDS (L-SDS) and body-mass-index (BMI) were calculated and recorded at every clinic visit, every 3 months for 8 ± 2 months.<p class=...

Identification of Characteristic Neurological Complications in Infants with Achondroplasia by Routine MRI Screening

Dougherty Harry , Shaunak Meera , Irving Melita , Thompson Dominic , Cheung Moira S

Background: Achondroplasia is the commonest type of skeletal dysplasia with an incidence of 1 in 20,000 and is due to recurrent and dominantly transmitted, activating mutations in Fibroblast Growth Factor Receptor 3 (FGFR3). Complications during infancy include foramen magnum stenosis and hydrocephalus which may lead to neurological morbidity and sudden unexplained mortality. Early detection and appropriate neurosurgical management can prevent these complications. How...

Bone Biochemistry in Children with Fractures Presenting with Suspected Non-accidental Injury

Forbes Owen , McNeilly Jane , McDevitt Helen , Houston James , Ahmed S. Faisal , Mason Avril

Introduction: Fractures have been recorded in up to one third of children who have suffered from physical abuse. The British Paediatric and Adolescent Bone Group (BPABG) position statement on vitamin D states that the level of 25 hydroxyvitamin D is not relevant to causation of fractures unless there is radiological or biochemical evidence of rickets. Clinicians are often asked in the court setting about the relevance of abnormal serum investigations in children who have fract...

The Effect of Growth Hormone Treatment in Children after Hematopoietic Stem Cell Transplantation

Hoekx CA , Bresters D , Le Cessie S , Scholte C , Oostdijk W , Hannema SE

Background: Hematopoietic stem cell transplantation (HSCT) has become more common in treating malignant and nonmalignant diseases in children. However, HSCT is associated with several late effects that can impair growth, like insufficient growth hormone (GH) secretion, hypogonadism and growth plate damage. Growth hormone treatment (GHRx) is offered but limited data are available on its effect on adult height.Objective: To evaluate the effectiveness of GH...

Testicular Development and Puberty in Boys with Duchenne Muscular Dystrophy: Results From the ScOT-DMD Study

Denker M , Joseph S , DiMarco M , Dunne J , Horrocks I , Ahmed SF , Wong SC

Introduction: Delayed or absent puberty is thought to be common in boys with Duchenne Muscular Dystrophy (DMD).Objective: To evaluate testicular development, function and puberty in DMD in a 12 months prospective longitudinal study.Methods: Thirty-four boys had assessment of puberty and testes volume by a single endocrinologist. Testes volumes were converted to Z-scores adjusted for bone age. Boys were divided into group A [Baselin...
