Objective: The maintenance of healthy and functional mitochondrial network via mitochondrial quality control (QC) mechanisms, is critical throughout life to respond to physiological adaptations and stress. Due to their role in energy production, mitochondria are exposed to high amounts of reactive oxygen species making their DNA (mtDNA) particularly vulnerable to oxidative damage. Mitochondrial dysfunction causes altered QC mechanisms (i.e. altered biogenesis, dynamics, autoph...

Purpose: The purpose of our study is to compare the effectiveness of PLA and RFA procedures in the treatment of benign thyroid nodules discussing indications, techniques, complication and outcomes derived from our experience.Method and materials: Thirty-eight patients (26F; 55±14) with benign thyroid nodules were treated, 15 with PLA and 23 with RF. Nodules were classified as thy2 through two consecutive fine-needle-aspiration (FNA) and selected for...

Purpose: Our purpose was to evaluate the safety and effectiveness of a virtual needle tracking system for US-guided percutaneous RFA of benign thyroid nodules (BTN) as compared to standard RFA.Method and materials: A STARmed (Korea) 18G bipolar RF electrode was used to perform the BTN ablation procedures. A US machine (LOGIQ E9, GE Healthcare) with a low magnetic field generator was used; electromagnetic sensors, calculating their mutual position, were s...

Introduction: Amino-Bisphosphonates (N-BPs) are potent inhibitors of the bone resorption, they inhibit enzymes of the intracellular mevalonate pathway required for prenylation of different important signaling proteins. In order to study the genetic basis of the variability in therapy response we have analysed the polymorphism of farnesyl pyrophosphate-synthase (FDPS) gene in 234 postmenopausal Danish women treated with N-BPs for 1 and 2 years.Methods: Th...

Metastases in the thyroid gland are very rare and their true incidence has not been clearly established. There are few reports of metastases to this gland and most of them are not detected in clinical practice.Although detection of metastases to the thyroid gland usually indicates poor prognosis aggressive surgical and medical treatment in isolated thyroid metastases may be effective as described for renal carcinoma.Malignant melan...

Sleep related breathing disorders (SRBD), due to bone mass and soft tissue swelling of the upper airways, are frequently reported by acromegalic patients, but sleep disorders other than SRBD were rarely studied in acromegaly. We evaluated 38 acromegalics (14 M, 24 F, age 52.8±2.3 yrs) by a structured interview for insomnia, excessive daytime sleepiness (EDS), SRBD, sleep related movement disorders (SRMD), circadian sleep disorders and parasomnias. Epworth sleepness scale ...

: Non-thyroidal-illness syndrome (NTIS) is present in chronic renal failure and considered an adaptive mechanism. However oxidative stress is linked to NTIS in a vicious circle, due to deiodinases alteration and negative effect on antioxidant levels or activity. One key antioxidant, protective toward ROS-mediated tissue damage, is extracellular superoxide-dismutase (ec-SOD), present in extracellular matrix and with a role in mediating nitric oxide-induced signaling. ec-SOD is ...

It is well known that heart failure is associated with oxidative stress (OS). Reactive oxygen species in fact influence sarcolemmal and mitochondrial ione channels, which are responsible for cardiomyocyte excitability and are important in myocardial remodeling after a myocardial infarction. The decrease of anabolic axes can have a role in the progression of the illness.In order to evaluate the relationship between growth hormone deficiency (GHD) and inde...

Background: The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic disease (Covid-19) is associated with the onset of thyroid dysfunction via multiple mechanisms. Patients hospitalised for severe Covid-19 disease may develop painless atypical thyroiditis coexisting with non-thyroidal illness syndrome, which determines transient thyrotoxicosis with quick restoration of euthyroidism during the following weeks. However signs of thyroiditis at ultrasound and sci...

Objectives: SARS CoV-2 infections have been associated with the onset of classic subacute thyroiditis (SAT) or atypical SAT, observed in 10-15% of patients hospitalized for severe COVID19 disease (COV-A-SAT) and characterized by absence of neck pain, mild thyrotoxicosis associated with non-thyroidal illness syndrome and thyroiditis-like areas which may persist in the thyroid gland up to 12 months following SARS-CoV-2 infection, despite normalization of thyroid function. Little...
