Background: Cushing’s syndrome (CS) is caused by endogenous cortisol excess and is associated with significant morbidity. Twenty-four-hour urinary cortisol is one of the most useful tools to diagnose CS although it has limitations, especially in “mild” and “subclinical” forms of cortisol excess. We hypothesized that given the diurnal rhythm of physiological cortisol secretion, night-time urinary glucocorticoid excretion should be lower than day-time ex...

Background: In recent years, increasing cases of congenital hypothyroidism (CH) with in situ thyroid gland are identified. Outcome of children affected from CH with normally sited thyroid of normal size is still unknown. The objective of our study is to describe the natural history of this specific form of CH. Patients and methods: We retrospectively evaluated clinical, biochemical and instrumental data of 74 patients with diagnosis of CH with in situ thyroid...

Introduction: Congenital hypothyroidism (CH) with in situ thyroid gland (GIS) and non-autoimmune subclinical hypothyroidism (NASI) are functional defects of thyroid gland occurring at birth and after birth, respectively. In recent years, a higher incidence of these disorders has been documented. The etiology remains unclear, with only an almost 50% of cases attributable to mutations in known dyshormonogenesis-associated or TSH-receptor genes. Although replacement ther...

Background: In recent years, increasing cases of congenital hypothyroidism (CH) with in situ thyroid gland (GIS) are identified. Outcome of children affected from CH with normally sited thyroid of normal size is still unknown. The objective of our study is to describe the natural history of this specific form of CH.Methods: We retrospectively evaluated clinical, biochemical and instrumental data of 89 patients with diagnosis of CH and GIS, refer...

Introduction: Congenital hypothiroidism (CH) is the most common neonatal endocrine disorder, affecting up to one in 1500 to 2000 newborns, if mild forms of hypothyroidism with eutopic and normal-sized thyroid gland are included. It is caused by either dysgenesis or dyshormonogenesis. Recently a novel iodide transporter, SLC26A7 (a member of the SLC26 transporter family), whose dysfunction affects thyroid hormonogenesis in humans, has been identified. The main purpose of this s...

Background: The introduction of newborn screening for congenital hypothyroidism (CH) has led to prevent the most serious consequences of precocious deficit of thyroid hormone during child development, particularly neurological disability. However, little is known about long-term physical and psycho-social outcomes of CH after screening introduction.Objective: To evaluate physical and neuropsychological development and Quality of Life (QoL) in adult subje...
