A 5-years-old boy was admitted because of polydipsia and polyuria. His family history was unremarkable. After water deprivation test (10h), laboratory test showed high levels of serum sodium (150.1 mmol/L), low urine osmolarity (88 mOsm/kg) and high serum osmolarity (301 mOsm/kg) consistent with the diagnosis of central diabetes insipidus (CDI). He started therapy with oral desmopressin with clinical improvement. Brain MRI revealed pituitary stalk thickening (3 mm), no hyperin...

Type 1 Diabetes Onset: A Story of Innate and Adaptive Immune Cells?

Fitas Ana Laura , Martins Catarina , Alonso Anabela , Nunes Gloria , Pina Rosa , Amaral Daniela , Lenzen Sigurd , Lopes Lurdes , Borrego Luis Miguel , Limbert Catarina

Background: Type 1 diabetes (T1D) is a T cell-mediated autoimmune disease. A more complex immunological picture is being unraveled, with a key role of innate immune cells at disease onset and maintenance. For new therapies based on immune-modulation to be possible, immune characterization of T1D patients is crucial.Objective and hypotheses: We aimed to characterise innate and adaptive immune cells of T1D children at a well-defined ‘onset-window&#146...

Introduction: Turner's syndrome (TS) is associated with several manifestations the most frequent being short stature and hypogonadism. Some authors (Nadeem, 2012; Bakalov, 2008) reported that individuals with TS have increased risk of fractures, but the etiology and mechanism of bone fragility have not been yet fully elucidated and may be exacerbated by hormonal factors (Cintron, 2017; Soucek, 2015). Bone densitometry (BD) through the emission of double en...

Family Studies of CYP21A2 Gene Identify Different Haplotypes for Nonclassical 21-Hydroxylase Deficiency in Brazilian Population

de Paula Michelatto Debora , Grimaldi Larissa Magalhaes , Alpiste Marcel Costa , Baptista Maria Tereza Matias , Guerra-Junior Gil , Valente de Lemos-Marini Sofia Helena , Palandi de Mello Maricilda

Background: Congenital adrenal hyperplasia, one of the most frequent autosome recessive disorders, is caused by defects in steroidogenic enzymes involved in the cortisol biosynthesis. Approximately 95% of cases are caused by a deficiency of the 21-hydroxylase enzyme. Its deficiency leads to androgen excess, consequently, to virilization and rapid somatic growth with accelerated skeletal maturation. Mutations in CYP21A2 are responsible for different forms of 21-hydroxylase defi...

Background: Polybrominated diphenyl ethers (PBDEs) are widely used as flame retardants and have shown endocrine disruption properties in experimental studies. Preliminary studies in animal models have suggested a link between exposure to PBDE and alterations of puberty and reproduction.Objective and hypotheses: To investigate the association between the exposure to PBDEs and alterations of puberty in girls, referred for idiopathic premature thelarche (IP...

Introduction:Up to 20% of children with neurofibromatosis type 1 (NF1) develops low-grade optic pathway gliomas(OPGs) that can result in neuroendocrinopathy.The aim of the study was to identify prognostic factors for developing neuroendocrinopathies in patients with NF1 and OPGs before any treatment.Methods: Records of 117 children with NF1 and OPGs followed at 4 Italian centers between 1997-20...

Background: Primary adrenal insufficiency (PAI) is a rare life-threatening disorder. Data on PAI in children are scanty, with the exception of Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD).Objective and hypotheses: Evaluate etiology of PAI in a large cohort of children and characterize clinical presentation in subjects with PAI not due to 21-OHD.Method: Children followed in eight tertiary centers wer...

A 8 years and 7 months old male presented with short stature related to his target height. No history of bones fractures. The patient was 120.7 cm (- 1.77 SDS). Physical exam demonstrated peculiar facies, relative macrocephaly, delayed tooth eruption and pectus carinatum. He referred during the clinical evaluation diffuse bone pain and weakness, mostly exacerbated by sport activity. A first diagnostic investigation had already been made showing low serum alkaline phosphatase a...

Introduction: The Wilms tumor suppressor gene 1 (WT1) plays an essential role in urogenital and kidney development. Heterozygous germline mutations in WT1 have been classically associated with Denys–Drash (DDS) and Frasier syndrome (FS). Exonic missense mutations in the zinc-finger region are the cause of DDS and mutations affecting the canonic donor KTS splice site of intron 9 are the cause of FS. New phenotypes, as 46,XX testicular DSD...
