Introduction: Monogenic obesity refers to a group of rare, early-onset forms of obesity and accounts for about 7% of patients with severe pediatric obesity. Recent reports demonstrate the emerging role of Src-homology-2 (SH2) B adaptor protein 1 (Sh2b1), an important component in the leptin-melanocortin pathway, as a key regulator of leptin and insulin signaling, with possible roles in the pathogenesis of obesity and diabetes. SH2B1 deletions are found to be a...

Background: A virus initially considered benign in this age group, SARS-COV-2 has recently been associated with Pediatric Multisystemic Inflammatory Syndrome (PIMS), temporarily associated with COVID-19, a syndrome whose diagnostic determination has a vital relevance since it imposes unfavorable outcomes. This study aims to describe the sociodemographic characteristics of PIMS in Brazil and the factors associated with death by this syndrome.<p class="abste...

Background & Objective: Indigenous children in Canada have higher rates of obesity and type 2 diabetes mellitus (T2DM) and diabetes-related complications when compared to non-Indigenous children. Indigenous knowledge-based view of health encompasses a holistic approach with physical, mental, emotional, and spiritual health dimensions. This view of health will likely impact their engagement in interventions targeting obesity and T2DM. This systematic review...

Background: Insulinomas are very rare in childhood with sparse knowledge on the clinical aspects and the presence of Multiple Endocrine Neoplasia type 1 (MEN1).Methods: We conducted a multicentre retrospective review of patients diagnosed with insulinoma between 1995-2021. Clinical, biochemical, genetic, imaging and histological data were collected. In addition, follow-up and family data were obtained.<p class="abste...

Introduction: The soluble leptin receptor (sLR) is the main binding protein of leptin in the serum. It reflects the amount of membrane-bound leptin receptors (LEPR) as the sLR is produced by proteolytic cleavage of the extracellular domain of membrane-bound LEPR. Low sLR but high leptin levels were measured in patients with severe obesity. In patients with monogenic obesity caused by biallelic LEPR variants, sLR levels were found to be either undetect...

Background: Differences in sexual development (DSD) are rare diagnoses, which affect the chromosomal, anatomical or gonadal sex differentiation. Although comprehensive counseling of patients and parents/carers is necessary to ensure a positive coping with the diagnosis and a well-informed decision-making, standardised programmes are lacking. Empower-DSD is a government-funded project, which developed an age-adapted multidisciplinary education programme to impr...

Background: Within the government-funded project Empower-DSD, modular training programmes for children and young adults aged 6-24 years with the diagnoses CAH, Turner-syndrome, Klinefelter-syndrome or XX-/XY-DSD (including MRKH) and their relatives were developed to improve diagnosis-specific knowledge, skills and empowerment. Overall, 105 trainings were offered between August 2020 and September 2022 in 5 centres with DSD expertise in Germany.<p class="abs...

Background: Kinase suppressor of Ras 2 (KSR2) gene codes for a scaffold protein modulating intracellular pathways that involve MEK/BRAF cascade and AMPK signaling. KSR2 plays an important role in energy balance regulation, and KSR2 mutations were reported to be associated with obesity and insulin resistance in mice and humans. In transfected cells, several KSR2 mutations lead to impaired fatty acid oxidation, which improved under met...

Background: Hypopituitarism is characterized by deficiency of one or more anterior pituitary hormones. POU1F1 mutations are the second most frequent known cause of combined pituitary hormone deficiency (CPHD). Patients are typically deficient in GH, TSH, and prolactin, although two unrelated cases were reported with isolated GH deficiency (IGHD). To date, all POU1F1 mutations have been reported for the predominantly expressed alpha isoform, which is a transcr...

Objective: IGF-1 receptor mutations (IGF1RM) are a rare abnormality; however, affected patients exhibit severe postnatal growth retardations without catch-up growth. Although several cases of IGF1RM have been described, a comprehensive retrospective analysis of the potential benefit of rhGH treatment is still missing. The aim of this study was therefore to investigate baseline auxology, response to rhGH therapy and potential metabolic effects in patients with IGF1RM in compari...
