Introduction: In recent years, micro papillary thyroid carcinomas (mPTCs; ≤1.0 cm) are increasingly diagnosed. Although clinical course is usually favourable, disease persistence may occur and multiple treatments needed. We examined factors that could be predictors of clinical behaviour and disease persistence.Patients and methods: 478 mPTC patients (78.9% females) followed-up for 0.6–10 years were classified according to tumour size in group ...

Objectives: Patients with thyroid dysfunction due to AITD have been found to have increased oxidative stress. Possible associations of oxidative stress with thyroid hormone (TH) and thyroid autoantibodies (ThAb) levels in euthyroid patients with autoimmune thyroiditis have not been adequately studied. We examined possible associations of oxidative stress markers with TH levels and with the presence of ThAb in euthyroid women with Hashimoto’s thyroiditis (with or without T...

Objectives: In familial MTC there is genotype-phenotype correlation. The phenotype and clinical outcome in exon8 (G533C) carriers has not been well established.Methods: 95 patients operated for familial MTC (27.2% males) were followed for 0.9–30 years (mean 8.0, median 5.5 years). 45.3% (n=43) were exon8 carriers (exon8MTC) and the remaning were non-exon8MTCs (n=52, exons 10, 11, 13, 14, and 16). Pre-, postoperative calcitonin, ext...

Introduction: Differentiated thyroid carcinoma (DTC) has generally a good prognosis and is associated with prolonged survival. A minority of patients may have persistent disease and rarely aggravation during f/u. We investigated factors which may influence the persistence of disease in patients who had undergone ablation with I131.Patients and methods: 903 DTC patients were referred in our center from 1968 to 2012. Five hundred and forty-one (...

Introduction: Recently, small medullary thyroid carcinomas (sMTCs) (≤1.5 cm) are frequently diagnosed, occasionally as incidental findings in surgical and autopsy specimens. Their clinical course varies. We examined whether tumor size is a predictor of clinical behavior.Patients and methods: One hundred and one sMTC patients (36.6% males, 47.1% familial) followed-up for 0.9–35 years. Patients were classified according to tumor size (cm) in gro...

Introduction: Several studies have examined the association of the common PvuII polymorphism of the estrogen receptor alpha (ERα) gene with the risk of stroke. Data linking the polymorphism with the severity and outcome of cerebrovascular disease is lacking. We looked for possible associations of the PvuII polymorphism with stroke severity and short-term prognosis in a cohort of female stroke patients.Patients-Methods: We studied 302 postmenopausal ...

Introduction: DHEAS is among the most abundant sex steroid products of the adrenal gland. DHEAS levels have been repeatedly associated with cardiovascular disease, but data concerning cerebrovascular disease, especially in women, is lacking. In this study, we aimed to investigate the role of DHEAS in a female population suffering an acute stroke.Patients and methods: We studied 302 consecutive female patients presenting with an acute stroke hospitalized ...

Introduction: Autoimmune disease (AD) is more common in women than in men. Sex hormones may play a role. Sex hormone receptors (SHR) are expressed in cells of the autoimmune system. We investigated the possible role of hormonal parameters and of common gene polymorphisms of the estrogen receptor alpha (ESR1), beta (ESR2) and androgen receptor (AR) in the presence of AD in men.Methods: In total 227 men were studied; 125 had at least o...

Objectives: Glucocorticoids may affect cardiovascular risk. Polymorphisms in the glucocorticoid receptor (GlucR) gene have been associated with increased risk for cardiovascular disease. We investigated whether the common Bcl1 polymorphism of the GlucR gene (associated with increased sensitivity to glucocorticoids) may be associated with early markers of atherosclerosis.Methods: Two hundred and fourteen middle aged apparently healthy subjects (age &#8230...

A common polymorphism of the ERβ gene (AluI) located in 3′-UTR of exon 8 has been shown to be associated with clinical features of altered estrogen action in tissues where this gene is expressed. It has recently been shown that GnRH neurons express ERβ, indicating that this receptor may participate in the feedback regulation of gonadotrophin secretion. We therefore studied the association of gonadotrophin levels and the AluI polymorp...
