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: Hypoaldosteronism (HA), a cause of hypovolemic hyponatremia (HN) with urinary(U) sodium(Na) loss, is often underdiagnosed. We studied 28 patients with an episode of HA-induced moderate/severe hyponatremia.Methods: Retrospective 2012–2015. In all patients, Nadir(N) serum(S) Na <130 mmol/l (corrected for total proteins and glycemia), low internal yugular venous pressure, low ocular pressure. Addison’s Disease ruled (ACTH, cortis...

Introduction: Post-surgical hypoparathyroidism (PSHP) is a frequent complication following ENT surgery. Some patients with head/neck cancers require enteral nutrition (EN) due to dysphagia, mucositis after radiotherapy or chemotherapy, or post-surgical anatomical complications. Formulas of calcitriol are not suitable to be administered via enteral feeding tubes, and side effects of systemic antineoplastic treatment (nausea, vomiting) make calcium and phosphate serum levels dif...

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...
