The objective of the study was to evaluate the efficacy of second-line therapies in patients with acromegaly caused by a growth hormone (GH) and prolactin (PRL) co-secreting pituitary neuroendocrine tumor (GH&PRL-Pit-NET) compared to their efficacy in patients with acromegaly caused by a GH-secreting pituitary neuroendocrine tumor (GH-Pit-NET). This is a multicenter retrospective study of patients with acromegaly on treatment with pasireotide and/or pegvisomant. Patients were classified in two groups: GH&PRL-Pit-NETs when evidence of hyperprolactinemia and immunohistochemistry (IHC) for GH and PRL was positive or if PRL were >200 ng/dL regardless of the PRL-IHC and GH-Pit-NETs when the previously mentioned criteria were not met.

The purpose of our study was to develop a predictive model to rule out pheochromocytoma among adrenal tumours, based on unenhanced computed tomography (CT) and/or magnetic resonance imaging (MRI) features. We performed a retrospective multicentre study of 1131 patients presenting with adrenal lesions including 163 subjects with histological confirmation of pheochromocytoma (PHEO), and 968 patients showing no clinical suspicion of pheochromocytoma in whom plasma and/or urinary metanephrines and/or catecholamines were within reference ranges (non-PHEO). We found that tumour size was significantly larger in PHEO than non-PHEO lesions (44.

Article Synopsis
  • PCSK9 inhibitors (PCSK9i) are effective treatments for patients with high cholesterol who struggle to meet LDL-C targets or can't use other cholesterol-lowering meds.
  • A study involving 115 patients showed a significant reduction in LDL-C levels, with 84.6% meeting therapy goals, although some factors like female sex and specific medications influenced outcomes.
  • Mild adverse drug reactions occurred in 38.1% of participants, but most were manageable, pointing to overall safety despite some differences between the two drugs tested (alirocumab and evolocumab).

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.

Systemic infiltrative diseases are relatively rare conditions consisting of cell infiltration or substance deposition in multiple organs and systems, including endocrine glands. This article reviews endocrine changes in the main four diseases at epidemiological level: sarcoidosis, Langerhans cell histiocytosis, hereditary hemochromatosis, and systemic amyloidosis. Recommendations to endocrinologists for hormone work-up and management of patients with each of these conditions are provided.

Article Synopsis
  • The study investigated presurgical and surgical risk factors linked to intraoperative complications in patients with pheochromocytomas from ten Spanish hospitals between 2011 and 2021, involving 162 surgeries on 159 patients.
  • Findings revealed that 33.3% of the patients experienced intraoperative complications, with hypertensive crises being the most common, followed by prolonged hypotension and hemodynamic instability.
  • Factors increasing the risk of complications included higher levels of urine metanephrine and normetanephrine, larger tumor sizes, uncontrolled blood pressure before surgery, pre-treatment with doxazosin, and the absence of perioperative hydrocortisone treatment.

Purpose: To identify presurgical and surgical risk factors for postsurgical complications in the pheochromocytoma surgery.

Methods: A retrospective study of pheochromocytomas submitted to surgery in ten Spanish hospitals between 2011 and 2021. Postoperative complications were classified according to Clavien-Dindo scale.

Background And Objective: Differentiated thyroid carcinoma staging is increasingly important due to the current trends to a less intensive therapy in low-risk patients. The TNM system is most widely used, but other systems based on follow-up of several patient cohorts have been developed. When these systems have been applied to other populations, results have been discordant.
