Introduction: Glucose sensors are medical devices used in glycaemic control of patients with type 1 diabetes (T1D) . Its use prevents multiple capillary measurements, improving disease control and quality of life. However, these systems are not exempt from unforeseen events. The rise in the number of users has resulted in the increasing detection of local skin reactions by these devices, being the most frequent the eczematous ones, which may correspond to irri...

Background: Recurrent miscarriage (RM) is traditionally described as three or more consecutive pregnancy losses and remains a challenging condition, affecting 1-3% of couples trying to conceive. Although factors such as uterine abnormalities, maternal hypothyroidism and parental balanced translocations are associated with RM, in most situations the aetiology is unknown. The coexistence of RM and live births in many families suggests a potential association wit...

Background: Thyroid hormones (TH) play multiple effects on glucose metabolism. Some recent studies carried out in adult patients suggested an association between altered sensitivity to TH and type 2 diabetes, obesity, and metabolic syndrome. No studies are currently available on the presence of altered sensitivity to the action of TH in youths with prediabetes.Objective: To evaluate the relationship between sensitivity t...

Introduction: Neonatal Diabetes Mellitus (NDM) is characterised by severe hyperglycaemia, usually diagnosed in the first 6 months of life. Genetic diagnosis helps distinguishing between its different causes and between transient (TNDM) and permanent (PNDM) forms, with repercussions on the therapeutic approach and follow-up.Aim: Clinical and molecular characterisation of a series of NMD cases under endocrinological follow...

Introduction: Since the beginning of the coronavirus pandemic, an increase in cases of new-onset type 1 diabetes (T1D) in children and adolescents has been observed in many countries, including Brazil.Objectives and Methods: In this descriptive study, we aimed to investigate the frequency of new-onset T1DM and the frequency and severity of diabetic ketoacidosis (DKA) in a referral Brazilian University Hospital, 38 months...

Introduction: Congenital adrenal hyperplasia (CAH) is the most common genetic condition in the spectrum of differences of sex development (DSD). Surgery in DSD is a controversial topic and there is no consensus if to perform surgery, how to perform surgery, and when to perform surgery. The current study was designed to evaluate the current practice in CAH related surgical practice in girls.Patients and Methods: All cases...

Background: A total of 456 skeletal dysplasias have been classified by molecular, biochemical and/or radiological criteria, into 40 groups. Despite this, the precise, final diagnosis is often difficult due to the high phenotypic and genotypic variability.Objective: To improve the molecular and clinical diagnosis of skeletal dysplasias using a custom-designed next-generation sequencing (NGS) panel.Method: A total of 56 skeletal dysp...

Background: Congenital adrenal hyperplasia (CAH) is a rare condition characterised by adrenal insufficiency and a life-long risk of adrenal crises. There is a paucity of information on the epidemiology of acute adverse events in this population.Objective: To investigate the frequency, aetiology and consequences of acute adverse events attributed to adrenal insufficiency in CAH.Methods</stro...

Introduction: Depending on the underlying diagnosis, Disorders of Sex Development (DSD) can be associated with an increased risk of germ cell cancers. To date, however, knowledge regarding the indications and timing of gonadectomy is lacking.Methods: The International-DSD (I-DSD) Registry was interrogated for anonymised information regarding the diagnosis, karyotype, sex of rearing and timing of gonadectomy, if undertaken, of all individuals of any karyo...

Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a protease that regulates IGF-1 availability, causes postnatal growth failure and changes in bone size and density in humans and mice. The present study aimed to determine the effects of daily administration (from PND5 to PND35) of recombinant murine (rm) PAPP-A2, in comparison to rmGH and rmIGF1, on mouse auxology and bone microarchitecture in homozygous Pappa2 knock-out (ko/ko) mice of both sexes. Hormone treatm...
