Introduction: Fine-needle biopsy(FNB) is an essential diagnostic tool in the evaluation of thyroid nodules, however, follicular neoplasm(FN) does not exclude malignancy. Some sonographic and cytological features have been described as being associated with increased risk of malignancy. The authors aimed to identify demographic, sonographic and cytologic features associated with malignancy in patients with a cytological diagnosis of FN.Methods: Descriptiv...

Introduction: Central diabetes insipidus (CDI) is characterized by a deficient secretion of anti-diuretic hormone (ADH), in which a large volume of hypotonic urine is eliminated. Pituitary metastatic disease is rare, accounting for 1% of all excised pituitary tumors and generally involves the posterior pituitary. Neoplasms that more often originate pituitary metastases are breast and lung cancer. Breast cancer (BC) is associated with pituitary secondary involvement in 5.3 to 2...

Endogenous hypercortisolism and chronic glucocorticoid (GC) therapy reduce bone mass, increase central fat mass, alter adipokines and enhance cardiovascular risk. Surgery (pituitary, adrenal or for ectopic ACTH) can control hypercortisolism in 90% of patients in experienced hands, and is often followed by inhibition of the adrenal axis, requiring substitution therapy with GC for months or years. We have been interested in learning on long-term outcome of ‘cured’ CS p...

Background: Insulinomas are rare neuroendocrine tumours (4 cases/million patients per year), representing an important cause of hyperinsulinemia. Usually are benign and sporadic, but can be part of multiple endocrine neoplasias. To establish the diagnosis it is essential to document inappropriately high levels of insulin during episodes of hypoglycaemia.Aim: Retrospective analysis of the clinical files of the patients followed in our department since Jan...

Transthyretin (TTR) is a protein mainly synthesized by the liver and choroid plexus (CP) of the brain. Besides its role as a carrier for thyroid hormones, TTR also sequesters the amyloid beta (Aβ) peptide impairing its deposition in nervous tissues, and its concentrations in the cerebrospinal fluid (CSF) appear to be inversely correlated with Alzheimer’s disease (AD) onset and progression. Abundant evidence suggests that the depletion of progesterone (PROG) at menopa...

We present a 27 year-old female patient suffering from multiple sclerosis (MS) since 3 years ago. She currently consults for menstrual disturbances. She has not any neurological secuelae of MS now and she is not on medical treatment. She is with amenorrhea since 10 months ago, but she had been oligomenorrhea just before for 24 months. She doesn’t have any symptoms suspicious for other hormonal impairment. Physical examination is normal.The laborator...

Objective: In order to determine the plasmatic levels of leptin in adult Wistar rats (90 days +7 days) which had undergone specific types of stress, a prospective study was done in which the stimulus was presented in the proestrus stage and the samples, recovered by decapitation 24 h after the initial stimulus, were centrifuged and stored for analysis of leptin by radioimmunoassay (RIA).Methods: The rats were divided into four groups: Group I (...

Cyclic Cushing’s disease is a rare situation due to episodic hypersecretion of ACTH. Suspicion is raised when strong clinical stigmata occur, with normal basal values of cortisol and normal responses to dynamic tests. After performing several tests, particularly during phases without symptoms (well-being), the probability of successful diagnosis increases.We describe the case of a 33 years old female patient with full-blown clinical picture (weight ...

The choroid plexus (CP) produces cerebrospinal fluid (CSF) and forms the blood-CSF barrier, being involved in the maintenance of the extracellular milieu of the brain and secretion of several neuroprotective factors. There are several experimental evidences showing that androgens enhance cognition and act as potential protective factors against Alzheimer’s Disease. It has been shown that testosterone exerts neuroprotective actions against oxidative stress, apoptosis, and ...

*These authors contributed equally to this work.BackgroundRegular physical activity has a crucial role in the control of Type 1 Diabetes (T1D). Insecurity in the management of insulin therapy and fear for dysglycemia are barriers to the practice of exercise in T1D.AimTo identify barriers to regular physical activity in adult patients with T1D; to evaluate the impact of two ed...
