Background: Among their metabolic effects, GH and its mediator IGF1 have been reported to influence hematopoiesis. Indeed, GH/IGF1 axis promotes erythropoiesis and GH deficiency (GHD) has been associated with a normochromic and normocytic anemia both in adults and in children. In contrast, in vivo data on the effects of GH/IGF1 axis on leukocytes and platelets are scanty.Objective and hypotheses: To evaluate the effects of 4-years GH replacement...

Handling diabetes at a very early age is difficult, even more when a complementary diet has not yet started. There is increasing evidence supporting the use of CSII in infants but some tricks could be useful.Infant 1: 10 mo, admitted in cardiac arrest. ROSC after 3 minutes, severe DKA (pH 6,95). Transferred to PICU, received also plasma transfusions. Day 2: CGM Dexcom G6 was started and tests for pancreatic autoimmunity and genetic of ne...

Background: Silver Russell syndrome (SRS) is a rare imprinting disorder with prenatal and postnatal growth retardation and feeding difficulties. The main molecular causes are loss of methylation of the 11p15.5 imprinting control region (H19/IGF2) and maternal uniparental disomy of chromosome 7. Prader-Willi syndrome (PWS) is a complex neurodevelopmental imprinting disorder with neonatal muscular hypotonia, failure to thrive to insatiable appetite, sho...

Background: SHOX and enhancer regions on PAR1 disorders have variable phenotypic consequences such as idiopathic short stature (ISS) and Leri-Weill Dyschondrosteosis (LWD).Objective and hypotheses: The aim of this observational multicentric study was to describe phenotypes and genotypes of a large population with mutation on SHOX and adjacent regions and to identify a possible phenotype–genotype correlation.M...

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...

Background: The diagnosis of 46,XY disorder of sex development (DSD) due to 5-alpha reductase 2 (5α-RD2) deficiency has been based on testosterone:dihydrotestosterone (T:DHT) ratio, urinary steroid profiling and mutational analysis of SRD5A2 gene. The biochemical hallmarks of 5α-RD2 deficiency include increased T:DHT ratio. However, several difficulties are observed in the DHT measurement leading to misdiagnosis. The mutational analysis of the SRD5A2 has been propose...

Background: Seip-Berardinelli syndrome is a rare form of congenital lipodystrophy.Objective and hypothesis: To report a patient later diagnosed with Seip-Berardinelli syndrome referred initially for evaluation due to low weight gain.Population and/or methods: We performed the report of the case along with a literature review.Results: The patient was referred due to low weight gain. She was the second daughter...

Case Report: A preterm boy was born at 35 weeks gestational age by cesarean section due to fetal macrossomia and polyhydramnios, weight 4980g (4.3 SDS, Intergrowth 21st), length 53cm (3.1 SDS), 1-min-Apgar 2. He needed resuscitation after birth, and his glycemia was 20 mg/dL. At the Neonatal Intensive Care Unit (NICU), he presented with severe hypoglycemia (10mg/dL) and required intravenous glucose infusion rate (GIR) 10mg/kg/min that increased progressively u...

Purpose: Low areal bone mineral density (aBMD) is a well-known consequence of anorexia nervosa (AN). However, the impact of reduced energy expenditure on bone metabolism is unknown. This study assessed the effects of energy deficiency on bone remodelling and its potential interactions with glucose homeostasis and adipose tissue-derived hormones in AN, a clinical model for reduced energy expenditure.Methods: 50 women with AN and 50 age-matched controls (m...

Objective: To determine the prevalence of congenital hypothyroidism (CH) in children with dry bloodspot TSH (b-TSH) between 5 and 10 mIU/l in neonatal screening and evaluate their thyroid function evolution.Methods: Retrospective study of thyroid function in children born from 2003 to 2010 with b-TSH between 5 and 10 mIU/l who were put on treatment in the first two years of life due to serum TSH≥10 mIU/l. The prevalence of CH ...
