Introduction: Although it has been suggested that there is a strong association between acromegaly and premalignant colonic lesions and colon cancer, it seems that in real – life practice the adherence to ACRO colonoscopy guidelines might be lower than expected (as recently shown by M.Parolin et cols).Methods: We retrospectively reviewed the case records of the 54 patients with acromegaly seen in our center since 1994.We analyzed the findings of 27 ...

Background: Cross-sex hormone therapy (CHT) is known to lead to alterations in cardiovascular risk factor(CVRF).Objective: To assess changes in lipid profile and other CVRF in transsexual subjects receiving CHT.Materials and methods: Retrospective longitudinal study. We evaluated individuals with gender identity disorder following CHT, assisted in the Gender Identity Unit from 2015 to 2017. Primary endpoint was lipid profile change...

Premature Ovarian Insufficiency (POI) is defined as impairement of ovarian function in women under 40 years, with a incidence between 1-4% in women of reproductive age. Among the major identified causes of Premature Ovarian Insufficiency, genetic factors related with X-chromosome are widely described. However, autosome defects are less common found and are related generally with genetic mutations instead of structural abnormalities of them. Thefor, we report a relevant case of...

Introduction, material and methods: The BRAF isoform of RAF has been implicated in the pathogenesis of papillary thyroid cancer, but not of benign or follicular neoplasms. Also, BRAF mutations may confer a worse clinical prognosis than for papillary thyroid cancer without the BRAF mutation. Recurrence occurs more frequently when BRAF mutations are present. In addition, BRAF mutations are associated with extrathyroidal invasion, lymph node me...

BackgroundVitamin D has shown to play a role in multiple diseases due to its skeletal and extraskeletal actions (such as immunomodulation). In this sense, vitamin D deficiency has become a worldwide health issue. Few supplementation guidelines mention calcifediol treatment, its optimal dosing and treatment duration, despite being the direct precursor of calcitriol and the biomarker of vitamin D status.Objectives<p class="abstex...

Sex hormone-binding globulin (SHBG) is a circulating plasma glycoprotein produced by the liver, which in the blood binds estrogens and androgens with high affinity and regulates its bioavailability. Low plasma SHBG levels are associated with obesity, metabolic syndrome and non-alcoholic fatty liver disease. Importantly, epidemiological studies have demonstrated that low plasma SHBG levels is a risk factor for developing type 2 diabetes and cardiovascular disease. In the last y...

Objective: To evaluate the impact of a decision support system (DSS) based on artificial intelligence (AI) -KoiosDS- on ultrasound (US) image analysis and risk stratification in thyroid nodules.Material and methods: Retrospective US study of all thyroid nodules with histologic (AP) result from June 2020 to December 2021. Diagnostic performance of US with ACR-TIRADS, by six endocrinologists and DSS, before and after the use of AI was evaluated.<p clas...

Objective: Endogenous cushing syndrome (ECS) is a complex and rare disease. After treatment, 50% of cases have recurrence. The objective is to evaluate the prevalence of recurrences in patients diagnosed of ECS and its predictive factors.Materials and Methods: Analytical retrospective observational study with 19 ECS diagnoses cases followed-up from January 1999 to December 2023. Demographic (sex, age), clinical (cause, face plethora, fragile capillary, r...

Introduction: Percutaneous ethanol injection (PEI) or thyroid enolisation is a minimally invasive technique applicable to benign cystic thyroid nodules, not adhered to neighbouring structures, due to local compressive symptoms or aesthetic discomfort. Classically, the treatment of choice for these nodules has been simple aspiration, followed by surgery in refractory cases. Currently, PEI has emerged as an alternative to surgery due to its high efficacy, speed, safety, low rate...

Introduction: Jugular vein agenesis is an extremely rare condition and its prevalence is not well-established. Case reports in the medical literature are limited, emphasizing the rarity of this anatomical variation.Case Presentation: Agenesis of the jugular vein is a rare anatomical variation characterized by the congenital absence or significant underdevelopment of the jugular vein, an essential vascular structure in the venous drainage of the head and ...
