Scrotal color-doppler ultrasonography (sCDUS) and transrectal ultrasonography (trCDUS) provide crucial information about the clinical status of testes and male accessory glands. However, the US evaluation of the infertile male is still often considered as a second level diagnostic tool. To analyze the role of ultrasound in male infertility, in order to predict hypothalamic-pituitary-testicular axis function, 1120 records from infertile men were retrospectively evaluated (from ...

Introduction and Objective: The initial assessment of differentiated thyroid cancer (DTC) patients is based on the American Thyroid Association (ATA) risk stratification criteria. Dynamic risk stratification (DRS) of DTC patients takes into consideration the response to initial treatment being reassessed at 1–2 years and revealed significant shifts in the risk categories of DTC patients. We aimed to evaluate the long-term outcome of papillary thyroid cancer (PTC) patients...

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...

Several lines of evidence indicate an increased risk of adverse gestational outcomes in women with Hashimoto’s thyroiditis (HT) already as of TSH levels at early pregnancy >2.5mU/l, and definitely greater for TSH concentration >4mU/l. The latest guidelines recommend preconception TSH levels (pre-C-TSH) in HT women be maintained below 2.5mU/l, this threshold being expected to prevent hypothyroidism occurrence at early gestation.Objectives: To...

Purpose: The present study aims to investigate the effects of hyperprolactinemia (HPRL) and its pharmacological control with Cabergoline (CAB) on the risk of fractures in male patients affected by prolactinoma.Methods: Observational single-center study was conducted on 39 male patients (median age 49±12,4 y) with prolactinoma, including 37 with macroprolactinoma and 2 with empty sellae. In patients PRL levels at diagnosis (PRL 0’), PRL at evalu...

Background: Moving from childhood to adulthood is a challenging process for individuals with type 1 diabetes (T1D), transition has been defined as the planned movement from pediatric to adult department.Aim: To assess glucometabolic control, prevalence of autoimmune disorders, and use of glucose sensors in patients with type 1 diabetes after transition to adult care.Methods: We retrospectively evaluated HbA1c, prevalence of patient...

Purpose: Dopaminergic system is implicated in the development of sleep disorders, and dopaminergic agents are used in clinical practice to treat daytime sleepiness and sleep disorders. The present study aimed at investigating the effects of hyperprolactinemia and its control with dopamine-agonists (DA) on sleep quality, excessive daytime sleepiness (ESS) and risk of obstructive sleep apnea syndrome (OSAS) in prolactinomas.Methods: A single-centre study w...

Background: Acylcarnitines and sphingomyelins are key players of lipid metabolism at cytosolic, vesicular and cell membrane level. Their metabolism was found deranged in diseases of the hypothalamus-pituitary-adrenal axis. Little information is available about levels of these compounds in the bloodstream and their circadian fluctuations. Dried blood spots (DBS) allow multiple autonomous and painless collections per day. However, poor biological validation data are available ab...

Introduction: Lipidomics is an emerging approach to characterize circadian rhythm alterations due to diseases of the hypothalamus-pituitary-adrenal axis. Glycerophospholipids are membrane structural constituents and key players in cell signalling, homeostasis and inflammatory and immune responses. Among blood derivatives, serum may reflect the soluble fraction, whereas dried blood spot (DBS) may reflect the cell membrane fraction of these lipids. However, little information is...

Introduction: Recent studies demonstrated that circulating concentration of many metabolites fluctuates with circadian rhythmicity. However, detailed information on amino acid and biogenic amine daily variations is still lacking. Dried blood spot (DBS) sampling appears to be a convenient tool for studies requiring multiple daily sampling.Aim: To verify the validity of DBS as a suitable device, we compared serum and DBS levels and changes along the day of...
