Background: Adrenocortical carcinoma (ACC) is a rare and aggressive neoplasm with a 5-year survival rate <30%. Survival depends mainly on the stage at diagnosis, being surgery the only curative treatment.Objective: To report the clinical features, management and outcomes of a series of ACC in two Spanish tertiary hospitals.Material and methods: All patients with pathological diagnosis of ACC between 2000 and 2017 were included ...

Introduction: Both subclinical hyperthyroidism and type 2 diabetes (T2D) have been associated with an increase in cardiovascular disease risk and mortality. We aimed to assess the prevalence of newly diagnosed subclinical hyperthyroidism in a cohort of patients with T2D, and also to analyse the relationships between diabetes-related characteristics and the presence of subclinical hyperthyroidism.Methods: Nine hundred and thirty-three diabetic patients wi...

IntroductionLeukocyte recruitment is a key feature in (I/R)-induced tissue injury. We have developed and validated a novel method to study molecular mechanisms of leukocyte-endothelium interactions in the colonic microcirculation in vivo by use of inverted intravital fluorescence microscopy.Methods & ResultsIn male C57/BL6 mice the superior mesenteric artery was occluded 30 min and leukocyte rolling and ...

The TSH B/I ratio is normally reduced overnight and is substantially reduced in patients with overt central hypothyroidism due to h-p axis tumours before and after treatment. It is unknown if similar changes in the TSH B/I ratio in the absence of overt central hypothyroidism contribute to the increased TSH levels seen in cancer survivors who undergo h-p axis irradiation. Thus, we selected 9 patients with the highest TSH levels out of a previously reported cohort of 37 euthyroi...

Introduction: The clinical implications of QTc and P wave dispersion in patients with Cushing’s syndrome have not been studied previously. In this study, we aimed to compare QTc dispersion and P wave dispersion in patients with Cushing’s syndrome and healthy subjects.Material and method: Sixteen patients with Cushing’s syndrome diagnosed on clinical, laboratory and imaging findings and 16 age and sex matched control subjects were included....

Selenium (Se) is an essential trace element and is important for maintaining health and preventing disease. Se exhibits its biological function as the 21st proteinogenic amino acid selenocysteine (Sec). Different cis and trans acting factors are necessary for incorporation of Sec into proteins. Se can be transported and stored as Sec in selenoprotein P (SePP), a liver-derived protein which contains up to 10 Sec residues per protein in humans. Thus, SePP functions...

Introduction: Pheochromocytomas (Pheo) may appear sporadically (SPheo) or as an autosomal dominant inherited disease, named as familial PHEOs (FPheo). The latter are present in younger patients, and usually with multiple tumors, but may occur in patients with apparently simple sporadic tumors with no other syndromic features.Material and methods: Clinical data of all consecutive patients underwent surgery for Pheo over 35 years in two tertiary referral c...

Introduction: The serum calcium/phosphorus (Ca/P) ratio has been proposed to identify patients with primary hyperparathyroidism and chronic hypoparathyroidism (HPT) from healthy subjects. However, other disorders of the Ca-P metabolism might present similar biochemical profile of HPT, such as pseudohypoparathyroidism (PHP), for which the use of Ca/P can be useful. Aim: To test the performance of Ca/P ratio in the diagnosis of PHP in comparison to healthy...

Methods: A prospective study in 35 patients hospitalized for AKI for two consecutive years was carried out. TFT (serum thyrotropin, TSH; free thyroxine, FT4; and total triiodothyronine, T3 concentrations) were measured in each patient on three occasions: at admission, at hospital discharge and at their first outpatient visit.Results: Total prevalence of alterations in TFT was 82.9% (n=29). Of those, euthyroid sick syndrome (E...

Background: Subclinical thyroid hypofunction and elevation of serum lipid concentrations are two factors that may act synergistically in the increase of cardiovascular risk in patients with type 2 diabetes. However, the association between subclinical hypothyroidism and dyslipidemia is a matter of debate.Objective: Our aim has been to assess whether incident hypothyroidism detected in a screening program is accompanied by elevations in the serum concentr...
