Background: Congenital combined pituitary hormone deficiency (CPHD) has various clinical presentations and can be caused by genetic defects related to pituitary development. We investigated the clinical features and genetic analysis in Korean patients with congenital CPHD.Method: Among 444 patients diagnosed with CPHD between 1994 and 2021 from Seoul National University Children’s Hospital, 43 patients with congeni...

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...

Background: Clitoromegaly usually is a sign of virilization, and should lead to prompt evaluation in order to allow adequate treatment. Neurofibromatosis (NF) is a syndrome characterized by pigmentary changes, development of benign tumors of peripheral nerve and increased risk of other malignant tumors.Clinical Case: A five year old female patient was referred to the pediatric clinic of Hospital de Clínicas de Por...

Introduction: X-linked hypophosphatemic rickets (XLH) is characterized by a mineralization disorder in the growth plate and cortical and trabecular bones, resulting in bone deformities with anthropometric changes and potential alterations in body composition.Objective: To evaluate the body composition of 12 children and adolescents with XLH compared to healthy controls by anthropometric and densitometry data.<p class...

Introduction: Genetic investigation in patients with short stature allows diagnostic definition and impacts therapeutic decisions, clinical follow-up, and genetic counseling. That said, next-generation sequencing has created a new clinical challenge by allowing the identification of findings unrelated to the complaint that prompted testing. The ACMG published a list of actionable incidental findings that includes genes whose variants should be reported to pati...

Background and aim: Fibroblast growth factor 21 (FGF21) is produced and expressed in several tissues but mainly in the liver and adipose tissue, where it has endocrine and paracrine functions. Several experimental studies reported that FGF21 decreases lipogenesis, triggers beta oxidation of fatty acids, reduces hepatic ER stress and VLDL release and reduces fasting and postprandial triacylglycerols (TG). Consistently, several phase 2 trials with FGF21-agonists...

Introduction: Hypochondroplasia (HCH) is a form of mild dwarfism caused by heterozygous gain-of-function mutations in the fibroblast growth factor receptor 3 (FGFR3). FGFR3 is a negative regulator of endochondral bone growth, and individuals with HCH typically exhibit characteristics such as disproportionate short stature with shortening limb length, lumbar lordosis, and macrocephaly. Regarding recombinant human growth hormone (rhGH) therapy in children with H...

Introduction: Isotretinoin is used for treatment of dermatological diseases, such as severe acne. It’s also recommended for treatment of high-risk neuroblastoma and pediatric medulloblastoma, but in these cases higher doses are necessary.Case report: A 12-year-old male patient with poorly differentiated embryonal origin carcinoma in the posterior fossa and implants in the neuroaxis. Next-generation sequencing genet...

Background: Neuropsychiatric symptoms can be present in patients with central precocious puberty (CPP), with or without abnormalities in brain magnetic resonance imaging (MRI). However, they are especially common in those with CPP-related lesions.Aim: To assess the prevalence of brain lesions detected by MRI in a cohort of children with CPP and to evaluate the occurrence of neuropsychiatric manifestations.<p class="a...
