Background: AAAS is an autosomal recessive disorder characterized by adrenal insufficiency, alacrimia, achalasia and neurological symptoms. The disease-causing AAAS gene encodes for the ALADIN nuclear pore protein.Case presentation: Case 1: A girl (born to unrelated parents) presented at age 3.9 years with fatigue and hyperpigmented skin. Clinical examination was normal, clumsy gait was noted. Endocrine studies confirmed adrenal insufficiency (F=9 mg/ml,...

Background: Achondroplasia is the most common form of osteochondrodysplasia, characterized by abnormal bone and cartilage growth leading to dwarfism and short limbs. It is caused by autosomal dominant mutations in the FGFR3 gene, leading to constitutive activation of the FGFR3 receptor, inhibiting chondrocyte proliferation and disrupting normal bone growth. Vosoritide is a 39-amino acid CNP peptide analogue, indicated for treating achondroplasia in patients ov...

Background: Vitamin D-induced hypercalcemia can result from exogenous vitamin D intoxication, excessive endogenous production or mutations in enzymes involved in vitamin D metabolism.Case Report: We describe an 8-month-old infant referred to the emergency department with history of failure to thrive and weight loss over the past two months. He was consuming type 2 formula milk supplemented with vitamin D plus vitamin D a...

GR and GT are diamniotic monochorial preterm twins (32 GA), both AGA (GR: W -1 SDS, L -1.5 SDS; GT: W and L 0 SDS), with normal karyotype and array-CGH on amniotic fluid, with no major complications associated to prematurity. At birth GT presented bilaterally cryptorchidism associated with micropenis, GR presented normal male genitalia. In the first year of life a severe growth deceleration in length (from -3SDS to -5 SDS) was observed, mainly after six months of life in both ...

Background: Congenital hypopituitarism is a rare cause of pituitary insufficiency (incidence: 12–42 new cases/million per year; prevalence: 300–455 cases/million). The aetiology remains largely unclear: the most frequently correlated genetic abnormalities are those involving transcription factors implicated in pituitary organogenesis. The phenotype and neuroradiological findings associated with the underlying genotype may be highly variable (from an isolated hypopitu...

Background: Septo-optic dysplasia (SOD) is a congenital, rare anomaly (1:10 000) associated with optic nerve hypoplasia, midline brain abnormalities and pituitary hormone abnormalities. Genetic alterations associated are: HESX1, SOX2 and SOX3. SOD’s pattern of growth even without GH treatment has been reported to be often good.Objective and hypotheses: Evaluate SOD’s growth in patients followed in our Centre.Method: See F...

Background: SHOX-D is rarely diagnosed in early infancy as cause of short stature.Objective and hypotheses: Describe clinical characteristics of two girls with an early diagnosis of Leri-Weill dyschondrosteosis, admitted to our hospital because of severe short stature.Method: Mutation screening of SHOX and its regulatory regions was performed by MLPA. Family analysis was undertaken.Results: The first 1.3 year...

Background: The phenotype of SHOX aploinsufficiency is highly variable also in affected members of the same family with broad differences in severity of short stature, disproportion, presence of Madelung deformity.Case presentation: We present a family with a new mutation of SHOX gene. A 2.3 years old girl, born at term from unrelated parents, came to our observation for short stature. Her height was −2.02 SDS, arm span was normal, sitting heigh/he...

Background: Despite the metabolic syndrome in pediatrics is a well recognized entity, there is no unanimous consensus on exact value of MS to predict long-term cardiovascular risk. Hepatic Steatosis (HS) is another emerging condition associated to pediatric obesity.Objective and hypotheses: To evaluate the prevalence of MS in a large pediatric obese population, assess the relationship between MS and HS, and evaluating the possible role of HS in defining ...

Introduction: Familial glucocorticoid deficiency (FGD) is a rare autosomal recessive disease characterized by ACTH-resistant isolated cortisol deficiency. FGD usually presents with hypoglycemia, convulsions, prolonged jaundice, and marked skin hyperpigmentation in the early period of life. Several defects in MC2R, MRAP, MCM4, NNT, and TXNRD2 genes are related to FGD. In all these situations, plasma ACTH is high. By contrast, all reported cases of glucocorticoi...
