Cardiac Amyloidosis in Venezuela: A Pending Issue.

Cardiac amyloidosis (CA) is an infiltrative disease characterized by the deposition of misfolded proteins in cardiac interstitial tissue. Interest towards studying this pathology has been growing in the last decade, as new epidemiological insights have revealed that it is not as uncommon as previously believed. Likewise, advances in non-invasive diagnostic approaches and the identification of molecules that modify its long-term progression, even in terms of mortality, have also bolstered interest in CA.

Morphological, clinical, and functional efficacy in the short and medium-term after radiofrequency treatment of predominantly solid, large, and clinically relevant thyroid nodules in patients who are not candidates for surgery: The experience after 100 procedures.

Introduction: Thyroid nodules (TN) are a prevalent pathology that can generate morbidity, in which case the traditional treatment is usually surgery.

Objective: To analyse the efficacy of radiofrequency ablation (RFA) treatment as a therapeutic alternative in the combined clinical, morphological, and functional control of predominantly solid, benign and clinically relevant TNs in patients not subsidiary to surgery.

Materials And Methods: A descriptive, retrospective, case series study was carried out to assess the efficacy and safety of the use of RFA.

Inferior petrosal sinus sampling and stimulation with CRH: 15 years of experience in a tertiary hospital.

Background: Inferior petrosal sinus sampling (IPSS) is indicated in the diagnosis of adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome (CS), especially when the results of the initial diagnostic tests are discordant.

Objective: To describe the patients who underwent this invasive functional test in a tertiary hospital.

Methods: This was an observational study of a retrospective cohort of patients with ACTH-dependent CS and IPSS between 2004 and 2019.

[Risk factors for arterial hypertension in the adult population of an urban region of Ecuador].

Objectives . To determine the risk factors for arterial hypertension (HTN) in the adult resident population of the city of Cuenca, Ecuador Materials and methods A cross-sectional analytical study of adults selected via multistage random sampling who underwent clinical, anthropometric, and laboratory evaluations. The diagnosis of HTN was defined according to the JNC-7 criteria.
