It is now well established that hyperprolactinaemia is not rare and in the majority of cases is caused by a pituitary tumor, a prolactinoma. However, despite a plethora of relevant publications there are still certain questions that have not been adequately addressed: 1. What is the upper normal level of serum prolactin beyond which the condition should be characterized as hyperprolactinaemia …

PURPOSE: Several articles have demonstrated the high diagnostic performance of somatostatin receptor positron emission tomography (PET) in patients with neuroendocrine tumours (NETs). On the other hand, only a few studies have evaluated the detection rate (DR) of this imaging method in recurrent medullary thyroid carcinoma (MTC). We aimed to perform a systematic review and a meta-analysis of the DR of somatostatin receptor PET or PET/CT in patients with recurrent MTC to add evidence-based data …

People with diabetes mellitus type 2 (DM2) have a greater risk for premature morbidity and mortality due to cardiovascular disease than the general population: cardiovascular disease accounts for 75% of deaths in this population group. We examined whether or not the association of clinical cardiovascular risk factors (RF) with both …

Early experiences can modify regulatory factors affecting gene expression in such a way that, although the DNA sequence itself is not changed, the individual’s physiology and behavior is substantially influenced. In some instances these epigenetic effects are exerted upon exposure, while in other instances they are transmitted across generations …

Background: In overt hypothyroidism (OH) anemia is common, while less frequently basophilia has been described. In subclinical hypothyroidism (SCH), however, data on the distribution of peripheral blood cells are lacking. Therefore, we evaluated the effects of L-T4 replacement therapy on peripheral blood elements in female patients with SCH before and after restoration …

We present a 73-year-old man with isolated adrenocorticotropic hormone deficiency and “flexion contractures” syndrome along with a review of the relevant literature. The patient initially presented anorexia, vomiting, arthralgias, malaise, and weight loss, which progressively deteriorated during the subsequent 6 months. He was admitted to the hospital with fever, confusion, severe cachexia, sinus tachycardia, low blood pressure …
