Background: The annual worldwide incidence of childhood adrenocortical tumors (ACT) ranges from 0.3 to 0.38/million children below the age of 15 years. Only 1–2% of them are feminizing ACT occurring in prepubertal boys and presenting with gynecomastia that normalizes after tumor removal.Case report: We present a case of a feminizing ACT. The boy was referred for bilateral gynecomastia, appeared 6 months before, at the chronological age (CA) of 7.5 y...

Background: Klippel–Feil syndrome (KFS) is characterized by congenital fusion of cervical vertebrae and has a prevalence of 1:50 000. The phenotypic expression is variable, sometimes presenting with extraskeletal symptoms.Case report: A girl was referred at the cronological age (CA) of 10.3 years with a suspected diagnosis of Turner syndrome, due to the presence of webbed neck and progressive deceleration of growth velocity. The girl, born in Russia...

Background: Congenital hypothyroidism (CH) is the most common neonatal endocrine disorder, with an incidence of 1:3000 neonates, and one of the most frequent preventable causes of mental retardation worldwide. Most (65%) cases of primary permanent CH are due to thyroid dysgenesis (TD). However, a genetic cause is identified in less than 5% of CH due to DT.Methods: We performed WES (Whole Exome Sequencing) for siblings with childhood-onset TD and we analy...

Background: There is growing evidence of a correlation between fat and bone metabolism at both the clinical and molecular levels, although the systemic regulators have not been clearly identified. The receptor activator of nuclear factor kB ligand (RANKL) and its soluble decoy receptor, osteoprotegerin (OPG), are involved in bone resorption and vascular calcification. OPG levels has been related with insulin resistance in adult obese subjects.Objective a...

Background: Paediatric bone marrow transplantation (BMT) can lead to endocrine dysfunctions due to common pre-procedure protocols involving chemo and radiotherapy.Objective and hypotheses: To evaluate the prevalence and time-of-onset of endocrine dysfunctions after BMT in children and adolescents.Method: A retrospective cohort-study design was performed. The inclusion criteria were: age range less than 18 years old at the time of t...

Background: Linear growth in patients with congenital hypothyroidism (CH) born in 1970s and 1980s is reported normal.Objective and hypotheses: To evaluate whether the earlier diagnosis and the higher L-T4 starting dose lead to an improvement in growth and pubertal outcome over the last two decades.Method: Two-hundred and fifteen patients with permanent CH born in 1980s and 1990s (age at diagnosis 25.1&#177...

Introduction: The National Registry of Civil Status through circular 33 of February 24, 2015 instructed the guidelines for the allocation of a sex through an inscription on the Civil Registry of Birth for intersexual minors.Objective: To create clinical and medical awareness on the importance of making an accurate diagnosis of Congenital Adrenal Hyperplasia CAH in order to avoid adverse effects due the omission of the due diligence by violating of the pr...

In a retrospective study (1), we found that a GH<6.5 μg/L, IGF-I-WHO87/518 <30 μg/L and IGFBP-3<0.8 μg/mL confirmed GHD diagnosis with high diagnostic accuracy in neonates with clinical suspicion of GHD. GH and insulin negatively regulate IGFBP-2, and it was proposed to reflect GH status in the diagnostic work-out of GHD in childhood and adults. The accuracy of IGFBP-2 has not been set for neonates.Objective: To prospectively v...

The epidemic spread of obesity in children has triggered the commitment of scientific research, which has allowed us to understand its genetic basis; the different forms of genetic obesity share common clinical aspects, making it difficult to achieve a molecular diagnosis based only on our clinical suspicion. We report a female patient presented with neonatal hypotonia, hyperphagia and early onset excessive weight gain, strabismus and high hypermetropia. Regarding her neurodev...

Background: In Brazil, specially in the south, there is a high prevalence of p53 mutations – 1:300 compared to 1:5000-1:20000 incidence worldwide. (1) As a consequence, adrenocortical carcinoma as a cause of virilization in children is much more common in our practice.Clinical Case: M.P.O., a 32-month-old girl, was referred to our institution - Hospital de Clínicas de Porto Alegre - in May 2022 due to progre...
