Introduction: Today, atypical antipsychotics offer the advantage of less frequent extrapyramidal effects compared to conventional neuroleptics, but they are associated with weight gain and diabetes mellitus.Observation: A 31-year-old patient with positive diabetic heredity, followed for schizophrenia on Levomepromazine and Olanzapine. Having revealed his diabetes mellitus by a diabetic cardinal syndrome. Blood glucose= 3g/l. Urine dipstick shows ketonuri...

Introduction: Prolactinoma is the most frequent secreting pituitary tumor. They are usually treated with dopamine agonists (DA) (bromocriptine and cabergoline), which are very effective in most cases. DA resistance consists of the impossibility of reaching normal prolactin levels and/or reduction of the adenoma by at least 50%.Case presentation: We present the case of a 57-year-old man affected by visual disturbances and hypopituitarism (2019). Pituitary...

Background: Cushing’s disease, the most common cause of endogenous Cushing’s syndrome, is caused by a pituitary tumor secreting adrenocorticotropic hormone (ACTH). Careful selection of treatment and management of the disease and associated comorbidities are necessary to improve prognosis.Case Presentation: A 32-year-old patient came to our observation for appearance of weight gain with abdominal obesity, hirsutism and amenorrhea. On suspicion o...

Introduction: Esthesioneuroblastoma (ENB), also known as olfactory neuroblastoma, is a malignant neuroendocrine tumor of the nasal fossa that arises from neurosensory receptor cells of the olfactory epithelium. It represents 3% of all nasal tumors. It presents a slow and progressive evolution that primarily affects the upper nasal mucosa and cribriform plate, with subsequent extension to the entire cavity and paranasal sinuses and can invade the orbit and cranial base.<p c...

Introduction: Non functioning pituitary adenomas (NFPAs) are the most common type of pituitary tumors and are often invasive, resulting in high relapse rates. The post-surgical treatment for NFPAs remains a debated issue and include radiation therapy and additional surgery. Several clinical studies have demonstrated that dopaminergic and somatostatin receptors (SSTRs) are widely expressed in NFPAs. Furthermore, recent studies have shown the potential effectiveness of somatosta...

Objective: Environmental rhythmicity seems able to affect the hypothalamic-pituitary-gonadal axis in animals, but the extent of its influence in humans is still controversial. This study was designed to evaluate seasonal fluctuations of the main hormones involved in the hypothalamic-pituitary-gonadal axis in men, using a big data approach.Methods: An observational, retrospective, big data trial was carried out, including all testosterone, luteinizing hor...

Background: Pituitary tumours (PT) are generally benign, but they can rarely show an aggressive behaviour, invade surrounding structures and/or grow/recur despite multimodal treatment, making their management extremely challenging. According to the latest guidelines, temozolomide (TMZ) can be an option after failure of standard therapies in aggressive PT, while little data are available on alternative approaches such as peptide receptor radionuclide therapy (PRRT). Herein we r...

Objectives: Vandetanib (V) is an important drug in the metastatic medullary thyroid cancer (MTC) treatment. The objective of this study was to evaluate the presence of predictors of V response, in short and long period, in locally advanced or metastatic MTC patients (pts).Methods: Seventy-nine locally advanced or metastatic MTC pts with progressive or symptomatic disease, referred to our Center between 2007 and 2018 and already treated surgically and wit...

Introduction: People living with human immunodeficiency virus (HIV) are at increased risk of developing metabolic disorders, such as obesity, dyslipidemia, insulin resistance, diabetes and hypertension; which may also be associated with hypercortisolism. Due to the similarity between the metabolic changes present in these two clinical situations, several studies have evaluated whether HIV-infected patients have increased levels of cortisol, but the results are not consensual. ...

Background: Many chemicals present within the environment, as well as natural and artificial components of our diet, have the potential to interfere with the physiological role of hormones, interfering with hormone biosynthesis, signalling or metabolism. In the last years AMH, a protein secreted by granulosa cells, has emerged as a reliable marker of ovarian reserve. It is largely accepted the influence of age and smoking on AMH serum levels, although a clear effect of environ...
