Background: Hyperinsulinaemic hypoglycaemia (HH) is characterized by the dysregulated secretion of insulin from the pancreatic β-cell. It is a major cause of severe and persistent hypoglycaemia in the newborn period. The rapid diagnosis and avoidance of recurrent episodes of hypoglycaemia are vital in preventing brain damage.Objective and hypotheses: To assess if the serum insulin measured at the time of hypoglycaemia in neonates with HH could be co...

Background: Vitamin D is an essential hormone in the homeostasis of calcium. Its main source is sun exposure. Changes in lifestyle and migratory movements have favored the reappearance of vitamin deficiency in our country.Method: We present three cases of newborn with hypocalcemic seizures, secondary to maternal vitamin D deficiency. Mother’s origin was North Africa.Results: Case 1: 7 days old male brought for several episodes...

Background: Neurogenic diabetes insipidus (NDI) is extremely rare in the neonatal period. In most cases, it’s secondary to CNS injury. The clinical presentation in this group (particularly in preterm) is unspecific and a high degree of suspicion for the diagnosis is necessary.Objective and hypotheses: Diagnose NDI in a neonate with sodium and diuresis instability.Method: We present a case report.Results:...

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare inherited disease characterized by mineralocorticoid resistance with subsequent salt wasting, hyperkalemia, metabolic acidosis, and elevated plasma renin and aldosterone levels.Patients and methods: We report a male newborn that presented with failure to thrive and sustained hyponatremia during his early postnatal period. He was conceived after IVF (twin pregnancy) and prematurely born by cesare...

Background: Disorders of sex development (DSD) are congenital conditions in which chromosomal, and gonadal or anatomical sex is atypical.Objective and hypotheses: We describe the case of a 46,XX newborn with ambiguous genitalia. 46,XX DSD set in differential diagnosis disorders of gonadal development (ovotesticular DSD, testicular DSD, gonadal dysgenesis), androgen excess of fetal (mainly congenital adrenal hyperplasia due to deficiency of 21-hydroxylase...

Background: In the optimal care of children with DSD, it is considered good practice to work within a multidisciplinary team (MDT) and engage in opportunities for professional development.Method: To explore the current models of MDT practice and the extent of professional development in specialist DSD centres, an international survey of 124 paediatric endocrinologists, identified through DSDnet and the I-DSD Registry, was performed in 2014.<p class="...

Background: Primordial dwarfism (PD) is a phenotype characterized by profound growth retardation and microcephaly that is prenatal in onset. Recently mutations in genes involved in ciliogenesis have been described in patients with primordial dwarfism phenotype. In 2012 mutations in rotatin (RTTN), a protein involved in cilia structure and function, have been described in in individuals with bilateral diffuse polymicrogyria, but not growth failure.Case pr...

Background: Craniosynostosis, defined as the premature fusion of the cranial sutures, presents many challenges in aetiology. One known form associated to steroid biosynthesis impairment is the Antley-Bixler Syndrome (ABS). ABS-phenotype and normal steroidogenesis have FGFR mutations, whereas those with ambiguous genitalia and altered steroidogenes should be recognized as possibly having P450 oxidoreductase deficiency, with mild do moderate 17 OH progesterone (17HOP) elevation ...

Background: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders characterized by a defect in cortisol biosynthesis. The most common form of CAH is the 21-hydroxylase deficiency (21-OHD), however, the incidence and the etiologic spectrum of other forms of CAH were not reported.Objective and hypotheses: This study describes the etiological distribution and clinical characteristics of CAH in a single academic centre.<p class...

Background: Hypothyroidism has been associated with cognitive and motor impairments, the degree to which mild hypothyroidism, or subclinical hypothyroidism impacts mood and cognitive functions and whether these symptoms respond to treatment, remains controversial. Furthermore, hypothyroidism is associated with an increased susceptibility to depression and reductions in health-related quality of life.Objective and hypotheses: Recent longitudinal studies s...
