Background: Patients who have received an hematopoietic stem cell transplantation (HSCT) have more risk of endocrine complications (hypothyroidism, hypogonadism, and growth retardation) but the incidence of diabetes after HSCT is not as well known. The pathogenesis of the diabetes is not well established, and is believed to be multifactorial: chemotherapy, pancreatic irradiation, inflammatory cascade and cytokines, steroids and predisposing genetic factors.<p class="abstex...

Introduction: Developing an acute onset thyroid nodule is rare in children and usually associates with infectious or neoplastic disease; when linked to hyperthyroidism, the most likely diagnosis is toxic adenoma.Clinical description: 9-year-old boy with no relevant medical history was seen at the emergency department for acute cervical pain and tumor involving the left thyroid lobe with no inflammatory signs or history of trauma. Physical examination rev...

Introduction: Thyroid dyshormonogenesis is a heterogeneous group of hereditary diseases produced by the total/partial blockage of the biochemical processes involved in thyroid-hormone synthesis and secretion. Many genes are involved in this process. PAX8 is a transcription factor essential for thyroid-gland morphogenesis and synthesis of thyroid hormones, since it activates TG, TPO and TSHR gene transcription. More than 50 PAX8</...

Objective: To describe efficacy and security of treatment protocol with gonadotropins in adolescents with hypogonadotropic hypogonadism (HH).Methods: Prospective study of patients with HH who received hGH and rhFSH in puberty. HH diagnosed during first months of life or in adolescence (testicular volume<4cc in >16 year-old with FSH<1.2UI/L, testosterone<40ng/dL and GnRH-test with LH-peak<6UI/L)<p class...

Introduction: Diabetes insipidus (DI) is a rare disease in children. In most cases it is acquired and central in origin (CDI). The most frequent cause of acquired CDI is brain tumor and idiopathic forms represent between 20-50% of cases, depending on the series. Autoimmune hypophysitis is a rare cause of DI and is a presumptive diagnosis with a suggestive brain MRI and ACTH and TSH deficiencies as the most common hormonal involvement, although it can manifest ...

Background: Epigenetic alterations due to maternal obesity may contribute to an increased metabolic risk in the offspring. IRS1 has a critical role in insulin signalling and its methylation has been previously associated with body fat distribution and glucose metabolism in human adipose tissue. The relationship between IRS1 methylation in birth tissues and obesity parameters in the offspring is unknown.Objective: To iden...

Introduction: Differential diagnosis of partial central diabetes insipidus (PCDI) and primary polydipsia (PP) can be challenging. Copeptin is the C-terminal segment of the vasopressin precursor peptide that represents a novel and stable biomarker. Arginine infusion produces a nonosmotic stimulus that causes an increase in copeptin concentrations in healthy subjects. Arginine-stimulated copeptin concentrations have been used to differentiate between patients wi...

Introduction: Pituitary adenomas (PPAs) are uncommon in childhood and adolescence, accounting for 2-6% of all intracranial neoplasms. Most data are based on case reports and only a few series have been reported. Delayed puberty, short stature, galactorrhea and weight gain are common features at presentation in pediatric patients. Functional tumors constitute a vast majority (90%) of PPAs including corticotropinomas in the first decade followed by relative upsu...

Introduction: Both the innate and adaptive immune responses are deregulated in individuals with obesity and are a key driver of its associated metabolic alterations. Although the anti-inflammatory growth differentiation factor 15 (GDF-15) is a candidate protein against obesity, its mechanisms regulating the immune responses are not fully understood.Methods: We examined whether serum GDF-15 was related to serum levels of ...

Introduction: It is known that excessive gestational weight gain can cause an adverse intrauterine environment and increase the risk of cardio-metabolic diseases in the offspring. Epigenetics could be one of the mechanisms involved in this regulation.Objective: We aimed to study the DNA methylation profile of umbilical cord tissue that is associated with gestational weight gain (GWG), and its relationship with cardio-met...
