Backgrounds: The prevalence of congenital malformations (CM) is higher in infants referred with capillary (c) TSH elevation on newborn screening. However, establishing the prevalence of CM ± dysmorphic syndromes in true congenital hypothyroidism (CH) requires careful distinction between true and transient CH.Objective: To determine the prevalence of CM ± dysmorphic syndromes in all infants referred with TSH elevation on newborn screening in Sco...

Background: Cardiofaciocutaneous syndrome (CFCS) is a rare autosomal dominant (AD) condition characterized by cardiac abnormalities, a distinctive craniofacial appearance and short stature. Endocrine manifestations include GH deficiency and precocious puberty. CFCS is part of the RASopathy group including Noonan, LEOPARD, and Costello syndromes. The four associated genes are BRAF (~75%), MAP2K1 and MAP2K2 (~25%), and KRAS (<2%). Most individuals represent new sporadic muta...

Background: ACTH deficiency (ACTHD) is a potentially life-threatening condition observed in many childhood survivors of intracranial. Time from tumor diagnosis and therapy to development of ACTHD cannot be ascertained from previous studies. This lack of knowledge has led to annual surveillance using low-dose ACTH stimulation testing (LDST) for 10–15 years following completion of therapy.Objective and hypotheses: To identify the incidence and timing ...

Background: There is limited evidence regarding the most appropriate method to investigate adrenal dysfunction in neonates. Our unit in Sheffield, UK measures a series of three serum cortisol levels to determine the need for a short synacthen test (SST). Other units use the SST as the first-line investigation in suspected adrenal insufficiency in neonates; however SST is more invasive with anaphylactic risk.Objective and hypotheses: To determine the prop...

Background: A reduced GH response to different stimulation tests have been documented in both children and adults with Prader–Willi syndrome (PWS), independently from obesity. Previous reports suggested the hypothesis of an age dependent derangement of the hypothalamus–pituitary axis occurring in PWS subjects.Objective and hypotheses: In this longitudinal study we re-evaluated the GH responsiveness to a combined test after long-term GH therapy ...

Background: The heterozygous mutation in the SRCAP gene (611421) on chromosome 16p11.2 causes a rare genetic disorder named Floating–Harbor syndrome (FHS). The clinical diagnosis of FHS is characterized by a triad of short stature with significantly delayed bone age; expressive language delay, usually in the presence of normal motor development; and a triangular face with prominent nose and deep-set eyes.Objective: To investigate the presence of SRC...

Background: Screening for congenital hypothyroidism (CH) has virtually eradicated the severe mental handicap associated with late or absent treatment. We have previously reported two audits of newborn screening for CH between 1979 and 2003 showing significant improvement from the first to more recent period.Objective and hypotheses: We aimed to audit the period 2004–2013 and report trends in timing of sampling, laboratory processing, delay between f...

Background: Hypoparathyroidism may manifest either as an isolated disorder or as a component of a more complex syndrome. Molecular genetic studies indicate that mutations in PTH, CASR, GCM2 and GNA11 are causes of isolated hypoparathyroidism (IH) and mutations in GATA3, TBCE, FAM111A, AIRE and TBX1 are associated with different complex syndromes with hypoparathyroidism.Objec...

Background: Hypoglycaemia precipitated by factitious insulin administration presents in a very similar way to hypoglycaemia caused by hyperinsulinism. It is difficult to ascertain clinically if the hypoglycaemia is secondary to exogenous administration or endogenous insulin secretion. Diagnosis is based on circumstantial evidence and biochemical tests which include insulin and C-peptide level.Objective and hypotheses: We would like to report a case of a ...

Background: Mixed gonadal dysgenesis (MGD) is the second most frequent cause of XY disorders of sex development (DSD). Genotype is either X/XY or XY, while the phenotype ranges from partial to complete gonadal dysgenesis, and from female to male external genitalia. Müllerian remnants are present in these patients because of insufficient or untimely foetal secretion of Müllerian inhibiting factor (MIF).Aim: To assess the therapeutic policy of ph...
