Background: In monogenic diabetes due to KCNJ11 and ABCC8 mutations that impair KATP- channel function, sulphonylureas improve long-term glycaemic control. Although KATP channels are extensively expressed in the brain, the effect of sulphonylureas on neurological function has varied widely. We evaluated published evidence about potential effects of sulphonylureas on neurological features, especially epilepsy, cognition, motor function and muscular tone, visuo-...

Introduction: Thyroid dysfunction is the most common side effect of amiodarone therapy, ranging from subclinical changes to overt clinical thyrotoxicosis (AIT) and/or hypothyroidism (AIH). Two major types of AIT have been described: type I usually develops in multinodular goiter or in preexisting Graves’ disease where an overload of iodine is responsible for the overproduction of thyroid hormones, and type II presents as a destructive thyroiditis, with release of pre-form...

Introduction: Treatment with recombinant growth hormone (rGH) is safe and has greatly improved the approach of children and adolescents with growth hormone deficiency (GHD) and other growth disorders. Some studies show that most of the height gain associated with GH treatment occurs in prepubertal years. The aim of our study was to evaluate the effect of age at start of the treatment on final height in children with isolated or GHD in a Portuguese cohort.<p class="abstext"...

Background: Aggrecan (ACAN) deficiency is a cause of autosomal dominant short stature with bone age advancement and premature growth cessation. There is limited data on the use of growth hormone (GH) treatment and aromatase inhibitor (AI) in this condition and their effect on adult height.Objective: To describe the improvement in predicted adult height (PAH), height SDS, and near adult height (NAH) in a 14-year-old boy w...

Background: Fanconi anemia (FA) is a rare, genetically and phenotypically heterogeneous, autosomal or x-linked recessive chromosome instability disorder characterized by multiple congenital anomalies, bone marrow failure, and increased susceptibility to specific malignancies. Other findings, including short stature, skin pigmentation, and endocrine abnormalities have been recognized, most notably GH deficiency (GHD), hypothyroidism, and hypogonadism.Case...

Background: Testicular tumours are an unusual cause of prepubertal gynecomastia. However, in boys with Peutz-Jeghers Syndrome (PJS), a rare autosomal dominant disorder caused by mutation in LKB1/STK11 gene, is mandatory to exclude this etiology, given the well-known association between PJS and Large-Cell Calcyfing Sertoli-Cell Tumor (LCCSCT). This mutation promotes aromatase overexpression in neoplastic Sertoli-cells, leading to gynecomastia.Case present...

Background: Type 1 pseudohypoaldosteronism (PHA1) is a rare syndrome characterized by unresponsiveness to aldosterone. Diagnosis is established by high levels of aldosterone and plasma renin activity, associated with findings of hypoaldosteronism (hyponatremia, hyperkalemia and metabolic acidosis). When the inheritance pattern is autosomal recessive it expresses as a severe systemic disease and the mortality rate is high, especially in the neonatal period....

11-year-old female, admitted in the emergency room due to postprandial hyperglycemia (350 mg/dL) in her father´s glucometer without ketosis or acidosis. She referred one-month evolution of mild symptoms, as polydipsia, polyuria, sporadic abdominal pain and nocturia.She was the first child of non-consanguineous parents, born full term at vaginal delivery with a birth weight of 3760g (90th percentile). Since 5-years-old her weight was betwe...

Introduction: Graves’ disease (GD), the main cause of hyperthyroidism in children, is caused by thyrotropin receptor stimulating autoantibodies (TRABs) that activate thyroid hormone synthesis, secretion and thyroid growth. Therapeutic options are anti-thyroid drugs (ATD), 131-I or thyroidectomy. This study reports the experience of a Tertiary Pediatric Endocrinology Unit.Methods: Review of GD patients diagnosed from January/2001 to October/2017. Res...

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare syndrome characterized by unresponsiveness or resistance to the action of aldosterone. It manifests with persistent salt loss, resulting in hyponatremia, hyperkalemia and metabolic acidosis. High levels of aldosterone and renin activity, confirms the diagnosis. When the inheritance pattern is autosomal recessive it expresses as a severe systemic disease. Often occurs in the neonatal period and presents with recurrent ...
