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...

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...

Background: FOP is an ultra-rare, severely disabling genetic disorder characterised by progressive heterotopic ossification (HO) following flare-ups. The median age at diagnosis is 5 years, and patients are managed by multiple specialties. No study to date has provided a longitudinal evaluation of FOP. Final data are presented for participants, aged <25 years, enrolled in the first 36-month, prospective, global natural history study of FOP (NCT02322255).</...

Background: Mixed gonadal dysgenesis is most commonly associated with 45,XO/46,XY karyotype.Objective and hypotheses: We report three cases that illustrate the genotype and phenotype variability of mixed gonadal dysgenesis.Methods: Data was extracted from Pediatric Endocrinology charts in a tertiary care centre after consenting the parents.Results: i) A 13 year old patient, 45,XO/46,X, isodicentric Y chromoso...

Background: Juvenile idiopathic arthritis (JIA) is a heterogeneous group of diseases associated with an increase of inflammatory cytokines that may to influence child growth. However this is already known, to date auxological data published of JIA patients during biologic treatment are incomplete and very heterogeneous.Objective and hypotheses: To evaluate the auxological features in a selected cohort of patients with JIA treated with biologic drugs....

Introduction: A 23-month-old male was admitted for evaluation of an enlarging neck mass, persistent rash, and periorbital edema.Case Description: The toddler had a strikingly large neck mass which had rapidly progressed over 1 month. He presented with a pustular and petechial rash primarily on his scalp which had been unresponsive to multiple treatment modalities. Initial work-up for his neck mass revealed a TSH of 19.7m...

Background: Avascular necrosis (AVN) is common in Sickle Cell Disease (SCD), frequently involving the femoral and humeral head and less commonly involving the spine. AVN leads to joint collapse, chronic pain and disability, and often requires joint replacement in early adulthood. There are no medical therapies for AVN in SCD despite the high burden of disease and there are no published reports of bisphosphonate therapy in this condition....

Childhood-onset growth hormone deficiency (CO-GHD) is topical at present due to the increasing understanding of underlying genetic aetiologies, influence on childhood growth, and future effects on adolescence and adult health. There is no previous Irish data of this group of children.Methods: A retrospective cohort study over 2 years (2013-2015) including all children diagnosed with GHD who received recombinant growth hormone treatment (rGH). Predictors ...

Background: CO-GHD can be caused by a variety of aetiologies, including pituitary or brain structural abnormalities, and increasingly recognised genetic mutations of pituitary transcription factors. Idiopathic GHD is a diagnosis of exclusion. POU1FI is a late pituitary transcription factor. Mutations of POU1F1 have autosomal recessive (AR) inheritance, and phenotypically present with a normal or small anterior pituitary gland on magnetic resonance imaging (MRI), they are assoc...

Background: 25-Hydroxyvitamin D (25(OH)D) deficiency is reported to be common in patients with rheumatoid arthritis and associated with disease activity, physical disability, and cardiometabolic intermediates; data in patients with juvenile idiopathic arthritis (JIA) are inconsistent.Objective and hypotheses: To assess serum 25(OH)D in children, adolescents, and young adults with JIA, and to identify the risk factors for vitamin D deficiency in JIA patie...
