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...

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: Bariatric surgery (BS) has emerged as the most effective treatment for severe obesity, but weight regain after surgery is an important issue. The aim of this study was to evaluate the impact of different surgical techniques on long-term dynamic weight loss pattern.Materials and methods: We retrospectively included 444 patients with BMI > 35 kg/m2 who underwent different BS techniques: Sleeve gastrectomy (SG; n: 80), ...

Introduction: Controversy exists regarding type 2 diabetes (T2D) remission rates after bariatric surgery (BS) due to heterogeneity in its definition and patients’ baseline features. We evaluate T2D remission using recent criteria, according to preoperative characteristics and insulin use.Materials and methods: Retrospective study from a cohort of 657 BS performed in a single centre (2006–2011) of which 141 (57.4% women) had T2D. Evaluation of a...

Introduction: Remission of type 2 diabetes (T2D) is a yearned outcome after bariatric surgery (BS). Attention to individuals who do not strictly fulfil remission criteria has been frequently left behind. The aim of this study was to evaluate metabolic control status in patients considered as diabetes ‘non-remitters’.Materials and methods: Retrospective study of 125 patients (59.2% women) with preoperative diagnosis of T2D who underwent BS in a ...

Introduction: The prevalence of hepatic steatosis in people with obesity is very high. However, what is relevant is to detect those patients with associated fibrosis. The aim of the present study was to predict by artificial intelligence (AI) using clinical-analytical parameters, the presence of liver fibrosis in the biopsy performed during bariatric surgery (BS) of patients with obesity.Subjects and methodology: Cross-sectional study of patients with ob...

Background: Bariatric surgery (BS) has proven to be an effective and sustainable long-term treatment in the remission of metabolic disorders. Bile acids (BAs) are involved in the improvement of metabolic comorbidities by acting on the distal ileum (releasing GLP1, PYY and FGF19) and on the microbiota. Our aim is to verify whether the formation of ABs depends on the type of bariatric surgery.Subjects and Methods: 21 patients (81% women) underwent bariatri...
