Background: Mucopolysaccharidosis I Hurler (MPS-IH is an inborn error of metabolism arising from the defective activity of alpha-L-iduronidase, an enzyme involved in the degradation of glycosaminoglycans (GAGs). As a result, the pathological lysosomal storage of GAGs in several tissues leads to multi-systemic complications, such as hepatosplenomegaly, progressive central nervous system deterioration, skeletal dysplasia and faltering growth, commonly resulting ...

Background: It is often difficult to establish whether hyperthyrotropinemia in preterm newborn is a simple physiologic energy sparing phenomenon or a true hypothyroidism requiring replacement treatment.Objective and hypotheses: This study aimed to find in what extent thyroid function in the preterm newborn can be influenced by clinical characteristics and complications.Method: We studied 35 preterm newborn, gestational age (GA) 32....

Background: DKA is the most serious life-threatening acute complication of T1D. Few data are available evaluating the possible role of anthropadiposity indexes in paediatric DKA in a selected population of prepubertal children. We aimed to identify the possible correlation between adiposity indexes and the presence and severity of DKA at T1D onset.Methods: 195 prepubertal children (84Female/111Male) diagnosed be...

Background: Vaptans, vasopressin receptor 2 antagonist, are used in adults to treat hyponatremia associated with congestive heart failure, cirrhosis, and the syndrome of inappropriate antidiuretic hormone (SIADH). To date, in paediatric patients with SIADH there are few data about use of vaptans, still considered off-label.Case presentation 1: A 9-yo female with surgically treated suprasellar astrocitoma developed chronic hyponatremia (121–128 mmol/...

Background: A close association has been reported between obesity and renal damage in adults, but evidence in childhood is still limited.Methods: We retrospectively studied 396 children and adolescents with obesity. Clinical, biochemical, and instrumental evaluations were performed. Patients were stratified according to the metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO) phenotypes. Kidney d...

Purpose: Leptin plays a key role in the regulation of body weight and other endocrine systems. Recently, impairment of leptin gene transcription due to genetic variations in a long-noncoding RNA, also referred as lncOb, has been described in mice. In humans, a correspondent polymorphism (rs10487505) has been associated with relatively low plasmatic leptin levels compared to obesity severity and with early obesity onset.Objectives...

Objectives: To evaluate the potential diagnostic role and sensitivity of T2-weighted DRIVE sequence in pituitary stalk (PS) identification and measurements in patients with hypothalamic-pituitary disorders. The degree of agreement and reliability between standard pre- and post-contrast T1-weighted images and T2-DRIVE will be tested in a large group of patients with pituitary dysfunction.Design: We searched for pituitary MRI reports using ‘T2-DRIVE&#...

Background: There is still need to define permanent GHD after adult height achievement in young adults with childhood-onset GHD (COGHD).Objective and hypothesis: To reassess GH response during transition.Method: We present the final data of 129 subjects (71M) recruited from a multicenter cross-sectional observational study, in whom anthropometrics, ITT (n=99), GHRH–arginine (n=122), IGF-1 evaluations were und...

Background: Ovarian and uterine development in relation to hormonal feedback mechanisms (E2, LH, FSH, and inhibin) has rarely been studied. Therefore, the age specific and longitudinally adequate replacement dose of estradiol to achieve normal maturation in terms of ovarian and uterine development during infancy, childhood and adolescence remains not well known. However, aromatase deficiency offers an excellent model to study the relevant estradiol dose needed to ac...

Introduction: Congenital adrenal hyperplasia (CAH) has an incidence of 1:14 000 to 1:18 000 worldwide. It is caused by autosomal recessive gene mutations. Neonates typically present with virilization at birth, or in shock, ‘salt-losing crisis’, around days 10–14 of life. Some children present later with simple virilizing CAH, often with milder compound heterozygous mutations. Reactive thrombocytosis is a rare manifestation in CAH. Gasparini <...
