Background: Pseudohypoaldosteronism is a rare condition of renal or systemic resistance to aldosterone, divisible into separate clinical presentations, each with a distinct physiological and genetic basis. Transient pseudohypoaldosteronism is a secondary form, characterised by reduced glomerulofiltration rate. It has been described in infants with obstructive uropathy and urinary tract infections.Method: We present five cases, presenting in infancy with ...

Background: GLUT1 deficiency syndrome (GLUT1DS) is a treatable epileptic encephalopathy resulting from impaired glucose transport into the brain. Clinical features comprise motor and mental developmental delay, seizures with infantile onset, deceleration of head growth often resulting in acquired microcephaly, and a movement disorder with ataxia, dystonia, and spasticity. While it is known that ketogenic diet may cause growth retardation, GH deficiency (GHD) may represent anot...

Background: Endogenous Cushing’s Syndrome (CS) is a rare disease in children, and corticotropin-independent forms are even scarcer. In childhood it carries a significant burden, resulting from both prolonged hypercortisolism long-term effects and treatment-associated morbidity.Case Report: A 23-month-old girl presented with irritability, central obesity with rapid weight gain and arrested linear growth, cushingoid facies with facial...

Background: Familial hyperaldosteronism type 1 (FH-1), is caused by the presence of a chimeric CYP11B1/CYP11B2 gene that produces high amounts of aldosterone in response to ACTH and severe hypertension. An early diagnosis and treatment are important, not only to manage hypertension but also to avoid possible deleterious effects of aldosterone on the endothelium and cardiovascular diseases.Clinical case: A 3 months old boy was referred for evalua...

Background: There is no effective adjuvant therapy for patients with advanced ACT. YAP1, a HIPPO pathway effector, interacts with Wtn\beta-catenin pathway and plays a crucial role in the maintenance of postnatal adrenal cortex and regulates cell proliferation and apoptosis in several tissues. We recently showed that overexpression of YAP1 associates with worse prognosis in our cohort of pediatric ACT (pACT).Aim: To analy...

Background: Small birth size followed by accelerated weight gain in early life is associated with an increased risk for age-associated diseases, such as cardiovascular disease (CVD) in later life. The underlying causes for this are largely unknown. Leukocyte telomere length (LTL) is a marker of biological age and short LTL is associated with increased CVD-risk. Subjects born small for gestational age (SGA) who remain short are treated with growth hormone (GH) to improve adult ...

Background: Subjects born preterm have an increased risk for ageing-associated diseases such as cardiovascular disease (CVD) in later life but the underlying cause is largely unknown. Telomere length (TL) is a usable index for ageing, with shorter TL indicating older biological age. Furthermore, short TL is associated with CVD.Objective and hypotheses: To investigate TL in subjects born preterm compared to term and to assess if TL is associated with risk...

Introduction: X-linked hypophosphatemia (XLH), due to PHEX mutation, is the most common genetic form of rickets in children. This rare disease is characterized by decreased tubular reabsorption and increased renal loss of phosphorus due to increased FGF-23 levels. In children, XLH is often manifested by short stature, rickets and bowel limbs deformity. Conventional treatment with oral phosphorus salts and calcitriol is not always well tolerated which has a pro...

Background: Neonatal diabetes (ND) is a rare monogenic form of diabetes presenting within the first six months of life. The most frequent causes include mutations in KCNJ11, ABCC8 and insulin genes, but up to 40% of patients remain without a molecular genetic diagnosis.Case presentation: Case 1: a female newborn of non-consanguineous parents, born at 35 weeks, SGA. She presented with hyperglycemia at second day of life...

Neonatal screening tests are used for the screening of genetic, endocrine and metabolic diseases. Preterm newborns have a higher false-positive and false-negative results in neonatal screening. The objective of this study was to estimate the prevalence of false-positive and false-negative results in the neonatal screening tests for phenylketonuria, congenital hypothyroidism, biotinidase deficiency and congenital adrenal hyperplasia (CAH) in preterm newborns in Curitiba, to ana...
