Introduction: Current guidelines recommend a single prolactin sampling for the diagnosis of hyperprolactinaemia. Nonetheless, in some patients, prolactin levels may normalize in a subsequent sampling or if prolactin is collected through a venous catheter some time after puncture. We aimed to assess the percentage of patients in which prolactin remained elevated in repeated sampling and to determine the best prolactin cutoff associated with persistent hyperprolactinaemia.<p...

Hyponatremia is a common disorder, especially among the elderly, and an important morbidity and mortality cause. Empty sella syndrome, on the other hand, is a rare entity, more common in women between their fourth and sixth decade of life, and endocrine dysfunction has been reported in 10–60% of the cases. A 68-year-old man, with a past medical history of essential hypertension and glaucoma, presented at the emergency room due to malaise, asthenia, somnolence and anorexi...

IntroductionThe most cost-effective, minimally invasive and accurate tool to discriminate benign from malignant thyroid nodules is a fine-needle aspiration biopsy (FNAB). However, 2%–24% of FNABs provide non-diagnostic results, which are a clinical challenge, particularly when this result is recurrent.AimTo determine the predictive factors for recurrent non-diagnostic FNAB in thyroid nodules.<p class...

IntroductionRecent published studies suggest that the anatomical location of the thyroid nodule may be associated with different risks of malignancy. However, the results are still sparce and little consensual.AimTo evaluate the frequency of nodules on different locations of the thyroid gland and to determine whether their location correlates with different malignancy risks.Methods<...

IntroductionHypoparathyroidism (hypoPT) is one of the most complications after thyroid surgery, usually as transient hypocalcemia. Permanent hypoPT due to permanent parathyoid lesion, despite being less frequent, is associated to long term consequences for both objective and subjective well-being and should be prevented. Identifying predictive factors associated with post- thyroidectomy hypoPT is thereby crucial.Aim<p class="ab...

The angiotensin II (AngII) hormone exerts a number of biological effects through the type 1 angiotensin II receptor (AT1R). One of the main targets of AngII are vascular smooth muscle cells, their stimulation activates many signaling pathways and results in gene expression changes.Affymetrix Gene Chip experiments were performed to analyze the effects of AngII stimulation on gene expression. For the determinations, aortic thoracic aorta from young male Wi...

Ectopic adrenocorticotropin secretion (EAS) accounts for 10–15% of cases of Cushing’s syndrome and comprises a spectrum of lesions from highly malignant tumours to a variety of less aggressive neuroendocrine tumours. Selective removal of the primary lesion is the optimal management. It is therefore mandatory to localize the source of ectopic ACTH.As no single test is accurate enough to distinguish the ectopic from the pituitary sources of ACTH,...

Background and aims: Thyroid nodular disease (TND) is a common condition in the general population. Malignant nodules occur in 5% of patients with thyroid nodules. Fine-needle aspiration biopsy (FNAB) is considered to be the most reliable method of differentiating benign and malignant thyroid nodules. The purpose of this study was to assess the accuracy of FNABs performed in our Hospital.Methods: We retrospectively reviewed the medical records of patient...

In the healthy liver, GH signals through multiple pathways to modulate hepatic function, with JAK2/STAT5b required to maintain circulating IGF1 levels. It has been previously reported that mice with developmental knockout of hepatocyte GHR, JAK2 or STAT5 develop steatosis associated with glucose intolerance, systemic insulin resistance and white adipose tissue (WAT) lipolysis. These changes are thought to be secondary to increased circulating GH, due to loss of IGF1 negative f...

IntroductionThe close relationship between cancer and thrombotic phenomena has been widely recognized and paraneoplastic organ infarctions may occur. Reports of papillary thyroid cancer associated to paraneoplastic phenomena are particularly scarce.Case reportA 39-year-old man with no prior relevant medical history was evaluated for acute onset of fever, malaise and mild pain referred to his left hypochondriu...
