Introduction: Overgrowth syndromes comprise an heterogeneous group of rare disorders characterized by generalized or segmental excessive growth commonly associated with additional features, such as developmental delay, visceromegaly and macrocephaly. They may present with inherent health concerns and, in some instances, an increased risk of tumor development requiring prompt diagnosis and appropriate referral.Objective: ...

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...

Background: GH administration restores normal growth in children with GH deficiency (GHD). However, current daily s.c. injection treatment regimens may be inconvenient leading to impaired adherence and subsequently suboptimal treatment outcomes. NNC0195-0092 is a novel, reversible albumin-binding GH developed for once-weekly administration.Objective and hypotheses: This was a randomised, open-label, active-controlled, dose-escalation trial (NCT01973244) ...

Background: Congenital hypothyroidism (CH) comprises a heterogeneous group of disorders that includes diseases of the hypothalamo-hypophyseal system. The latter are missed on TSH based screening programs leading to increased morbidity and mortality. Additional T4 determinations, allows an early detection of CH of central origin (CH-C).Objective and hypotheses: To report the findings of a neonatal screening program based on determination of TSH...

The LMNA gene encodes lamin A/C, intermediate filament proteins associated with the inner nuclear membrane. Mutations in LMNA gene cause a wide range of human diseases sometimes called ‘laminopathies’ that affect different organ systems depending upon the mutation. Most laminopathies involve tissue of mesenchymal origins, resulting in such features as cardiac disorders and/or muscular dystrophy, lipodystrophy or progeroid syndromes. The group of progeroid syndromes i...

Background: The aim of therapy in patients with congenital adrenal hyperplasia (CAH) is to use glucocorticoid doses as low as possible to achieve adrenal suppression. Both chronically increased androgen secretion and increased glucocorticoid exposure may adversely affect adult height and in some patients this therapeutic balance is difficult to achieve. In these particular cases aromatase inhibitors (AI) could be indicated with de aim to reduce glucocorticoid doses avoiding th...

Background: Costello syndrome may be associated with Hyperinsulinaemic Hypoglycaemia (HI), but this is usually a mild medically-responsive form.Objective and hypotheses: To describe the clinical characteristics, biochemical findings and challenging management of a case of Costello syndrome with severe HI.Method: Review of the patient’s medical records.Results: Male, born to non-consanguineous healthy par...

Background: Pseudohypoparathyroidism is a group of rare disorders characterized by tissue insensitivity to PTH and Albright hereditary osteodystrophy (AHO) due to inactivating mutations or epigenetic defects of the GNAS.Objective and hypotheses: Clinical features and molecular characteristics of patients with PHP have been examined.Method: We included 28 patients from 26 families with PHP1a and 1b. GNAS mutation analysis w...

Background: Achondroplasia and hypochondroplasia are more frequent types of skeletal dysplasia. De novo mutations in the fibroblast growth factor receptor 3 (FGFR3) gene are the principal cause. More than 95% of the cases of achondroplasia result from a mutation G1138A (Gly380Arg). In hypochondroplasia we usually (50–70%) found the change C1620A y C1620G, N540K (Asn540Lys).Objective and hypotheses: We describe an skeletal dysplasia...

Background: The lipodystrophy syndromes are a heterogeneous group of congenital or acquired disorders characterized by either complete or partial lack of adipose tissue (lipoatrophy). Berardinelli Seip congenital lipodystrophy (BSCL) is a rare metabolic disorder characterized by severe generalised lipodystrophy since birth, insulin resistance, and dyslipemia since early infancy.Case presentation: We report a 6-year-old girl who arrived from Pakistan with...
