FRAGILITY FRACTURES IN OLDER PERSONS WITH ALTERED THYROID FUNCTION

2016

Gli ormoni tiroidei sono peptidi che svolgono molteplici e complesse funzioni nell’organismo umano. Lo sche-letro è uno dei tessuti bersaglio degli ormoni tiroidei, ed una loro carenza o un loro eccesso ha importanti conseguenze sul tessuto osseo soprattutto nel periodo dello sviluppo e durante l’invecchiamento. I disturbi a carico della tiroide si osservano con maggior frequenza nei soggetti in età avanzata rispetto ai giovani. La tire-otossicosi è una causa nota di osteoporosi secondaria. L’ipertiroidismo conclamato e l’ipertiroidismo iatrogeno dovuto ad un eccesso nel dosaggio della terapia sostitutiva con ormoni tiroidei sono possibili cause di fratture ossee da fragilità. L’ipertiroidi…

Struma ovarii. Case report and revision of the literature

2011

Struma ovarii is a rare form of ovarian neoplasm, entirely or predominantly composed of thyroid tissue. This tumour generally has a benign biological behavior, although some cases of malignant transformation have been reported (5-10%). The tumour usually presents as an asymptomatic mature mass that may measure as much as 10 cm in diameter. The presence of ascites is possible (15-20%), and in a few cases the association of ascites and hydrothorax has been recorded (Pseudo-Meigs Syndrome); a close relationship between ascites and high levels of Ca-125, that may wrongly induce to a diagnosis of ovarian carcinoma is present. Other possible clinical consequences are compressive symptoms on adjac…

The 2015 European Thyroid Association Guidelines on diagnosis and treatment of endogenous subclinical hyperthyroidism

2014

Endogenous subclinical hyperthyroidism (SHyper) is caused by Graves' disease, autonomously functioning thyroid nodules and multinodular goitre. Its diagnosis is based on a persistently subnormal serum thyroid-stimulating hormone (TSH) level with free thyroid hormone levels within their respective reference intervals. In 2014 the European Thyroid Association Executive Committee, given the controversies regarding the treatment of Endo SHyper, formed a task force to develop clinical practice guidelines based on the principles of evidence-based medicine. The task force recognized that recent meta-analyses, including those based on large prospective cohort studies, indicate that SHyper is associ…

Thyroid Disorders in Old Age

2019

Thyroid disorders are more frequent in old age, especially in women. Overt thyroid dysfunction may manifest as aging itself or as age-associated disorders of other organs. Therefore, an accurate clinical suspicion is essential for their detection in elders with multiple comorbidities, malnutrition, and chronic polypharmacy. Because chronic diseases are more prevalent in old age, nonthyroidal illness is also common in this age group. Most thyroid nodules in older persons are benign, yet a comprehensive individualized evaluation is needed in order to timely detect malignancy. While there is still debate on the decision to treat or not to treat subclinical thyroid disorders, current recommenda…

Impact of Various Thermal Doses on the Oxygenation and Blood Flow in Malignant Tumors Upon Localized Hyperthermia

1984

Hyperthermia exhibits various direct cytocidal effects (Dickson, 1977; Overgaard, 1977; Suit, 1977). During heat treatment in vivo, several indirect mechanisms enhance the direct cell-killing capacity of hyperthermia. Therefore, the effective use of hyperthermia can overcome some of the well-known problems involved in modern radiation therapy at least in some malignant tumors.

Near-infrared light-responsive and antibacterial injectable hydrogels with antioxidant activity based on a Dopamine-functionalized Gellan Gum for wou…

2022

The development of wound dressings with combined antioxidant, antibacterial and tissue adhesion functions has been a difficult medical task for the treatment of wound infections. We synthetized a dopamine and PEG functionalized Gellan Gum (GG) to produce an injectable hydrogel with radical scavenging activity having both specific and aspecific antibiotic/antimicrobial properties. Using starting GG with different molecular weights, we obtained two derivatives that have been used to prepare the gel precursor dispersion, that undergoes gelation in the presence of colistin and dried microparticles (MPs) functionalized on the surface with polydopamine (pDA). Both were used to dope the hydrogel, …

Optimisation des techniques de chimiothérapie intracavitaire

2013

Introduction. In order to achieve a good effect, chemotherapy drugs need to penetrate into the peritoneal (HIPEC) or pleural tissue. Hyperthermia and high-pressure may enhance this penetration. The aim of this study was to evaluate their peritoneal effect and to establish the best technique to it. A feasibility study of an intrapleural high-pressure was an essential step to export these effects to the thoracic space. Methods. Four groups of pigs underwent an open HIPEC with a constant concentration (150 mg/l) of oxaliplatin during 30 minutes either in normothermia, or in hyperthermia (42-43°C); and either with atmospheric pressure or with high-pressure (25 cmH2O). Two more groups underwent …

L'hyperthermie provoque l'agrégation de FLIP et restaure l'apoptose induite par TRAIL

2014

The TNF-family member TRAIL (TNF-related apoptosis inducing ligand) is a cytokine involved in the immune anti-tumour surveillance. TRAIL is a promising agent currently under investigation for its anti-cancer properties with limited side effects on healthy cells. However, the use of TRAIL in oncology has been limited due to its lack of efficiency, mainly associated with cell resistance to apoptosis. The aim of this project was to study the interest of hyperthermia (or heat shock - HS) as an adjuvant for TRAIL therapy and the mechanisms involved in this sensitization.We have first evaluated the significance of this combination in a large variety of cancer cell lines known to be sensitive or r…

A comparative meta-analysis of TEMPS scores across mood disorder patients, their first-degree relatives, healthy controls, and other psychiatric diso…

2016

Background The Temperament Evaluation Memphis, Pisa, Paris and San Diego Auto-questionnaire (TEMPS) is validated to assess temperament in clinical and non-clinical samples. Scores vary across bipolar disorder (BD), major depressive disorder (MDD), attention-deficit/hyperactivity disorder (ADHD), borderline personality disorder (BPD) and healthy controls (HCs), but a meta-analysis is missing. Methods Meta-analysis of studies comparing TEMPS scores in patients with mood disorders or their first-degree relatives to each other, or to a psychiatric control group or HCs. Results Twenty-six studies were meta-analyzed with patients with BD (n= 2025), MDD (n=1283), ADHD (n=56) and BPD (n=43), relati…
