Background: Polycystic ovary syndrome (PCOS) is a complex endocrine genetic disorder, which is associated with increased metabolic and cardiovascular morbidity. Vitamin D or omega-3 fatty acids supplementation may alleviate the metabolic and reproductive complications of PCOS.Objective and hypotheses: To compare clinical, psychometric, biochemical, endocrine, bone and sonographic markers in vitamin D sufficient adolescents with PCOS, pre- and post- 6 mon...

Congenital hyperinsulinism (HI) is the most common cause of persistent hypoglycemia in infants and children. In the past 20+ years there have been tremendous advances in the understanding of the molecular genetics of HI, including the discovery of the mechanisms responsible for a focal form of the disease that can cured surgically. However, treatment options for non-focal HI continue to be limited, with only one drug currently approved for this indication. As a result of delay...

Introduction: Primary congenital hypothyroidism (PCH), defined as thyroid hormone deficiency, can be viewed as an anatomical, clinical, biochemical and radiological spectrum.Its etiology includes thyroid dysgenesis (85%) with defects in thyroid gland development and thyroid dyshormonogenesis (15%) with inborn error of thyroxine synthesis or release.There is growing evidence that precise characterization of ...

Introduction: The MODY diabetes (Maturity Onset Diabetes of the Young) belongs to monogenic alterations group, the mutation of the gene HNF-1α is the most common and present an autosomal dominant inheritance that causes dysfunction of the Beta pancreatic cell and alteration in the reabsorption of glucose to renal level, with age of variable presentations, it often leads to a misdiagnosis as type 1 diabetes mellitus.Description of the clinical case: ...

Behavioral studies suggest that brain satiety responses to food consumption are altered in children with obesity. We studied brain regions involved in satiety processing using functional magnetic resonance imaging (fMRI) before and after a test meal. Satiety-related hormonal changes were assessed. Fifty-four 9-11 year-old children with obesity (OB) and 22 children with healthy weight (HW) were studied. Subjects underwent two fMRI scans, one before and one after a test meal, an...

Introduction: Ovarian stimulation syndrome (OSS) in an infrequent disorder, in preterm infants under 30 weeks gestation. The are very few cases described in the literature. The immaturity, lack of gonadal axis feed-back or mutations in the FSH receptor genes, may explain its physiopathology. We present the case of a 26-week neonate with this syndrome.Case summary: 26-week newborn with extremely low weight (460g) born by emergency cesarean section due to ...

Introduction: The Immune Thrombocytopenic Purpura (ITP) and Graves Disease (GD) have in common an autoinmune physiopathology. ITP is characterized by a platelet count less than 100 × 106/l in the absence of other cause. On one hand, ITP has been associated with thyroid dysfunction, without developing GD. On the other hand, GD might develop with moderate thrombocytopenia, generally more than 100×109/l. It is described that in most cases ITP might...

Inactivating mutations of ß-cell KATP channels cause the most common and severe form of congenital hyperinsulinism (HI), a ß-cell disorder that results in dysregulated insulin secretion and persistent hypoglycemia. Children with KATPHI are typically unresponsive to diazoxide, the only FDA-approved drug for HI. Octreotide, an SST2-selective agonist peptide that inhibits insulin secretion, is used as second line therapy, but poor efficacy and SST2...

Background: The genetic etiology of non-syndromic HI remains unknown in over 20% of all cases, and over 50% of diazoxide-responsive cases. Non-coding variants in HK1 have been suggested to cause HI by linkage-analysis (Pinney et al., 2008). More recently, variants within a regulatory region of HK1 intron 2 were reported in 17 individuals with HI (Wakeling et al., 2022). These variants have been proposed to cause HI by disrup...

Background: Congenital hyperinsulinism (CHI) is a rare disease affecting neonates, infants, and children. CHI is characterized by dysregulated insulin secretion resulting in severe recurrent hypoglycemia. Early treatment is necessary to limit the risk of neurologic and developmental sequelae. Current treatment options are limited and inadequate. Dasiglucagon (DASI) is a glucagon analog suitable for continuous subcutaneous infusion which has been shown to raise...
