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.
