Objective To evaluate the current quality of thyroid ultrasound reports in Community Madrid. Methods Consecutive from patients evaluated endocrine outpatient clinics eight academic hospitals Madrid were assessed for during 2021 and 2022. Descriptions different features evaluated: number axes dimensions, composition, echogenicity, margins, shape, calcifications category suspicion.

Purpose Population-based and registry studies have shown that chronic hypoparathyroidism is accompanied by long-term complications. We aimed to evaluate the risk of incident comorbidity among patients with postsurgical in real-life clinical practice Spain. Methods performed a multicenter, retrospective cohort study including lasting ≥3 years at least follow-up visit between January 1, 2022 September 15, 2023 (group H).

Acromegaly is a rare disease with nonspecific symptoms acral enlargement being almost universally present at diagnosis. The estimated prevalence 40-125 cases/million but targeted universal screening studies have found higher (about 10 fold). aim of the ACROSAHS study was to investigate acromegaly and comorbidities in patients sleep apnea enlargement.

Purpose The identification of patients with chronic hypoparathyroidism who are adequately (AC) or not controlled (NAC) has clinical interest, since poor disease control is related to complications and mortality. We aimed assess the prevalence NAC in a cohort subjects postsurgical hypoparathyroidism. Methods performed multicenter, retrospective, study including from 16 Spanish hospitals lasting ≥3 years. analyzed biochemical profile wellness. For assessment we considered three criteria:...

Recent guidelines for the treatment of hypoparathyroidism emphasize need long-term disease control, avoiding symptoms and hypocalcaemia. Our aim has been to analyze prevalence poor control in a national cohort patients with hypoparathyroidism, as well evaluate predictive variables inadequate control.From nation-wide observational study including 1792 undergoing total thyroidectomy, we selected 260 subjects [207 women 53 men, aged (mean ± SD) 47.2±14.8 years] diagnosed permanent...

Summary Ectopic Cushing’s syndrome (ECS) is a rare disease associated with significant comorbidity. Among the causes of Cushing's syndrome, adrenocorticotropic hormone-producing extrapituitary tumours are rarely reported. This low frequency makes it difficult for physician to acquire experience in its management. In this report, we aimed describe clinical presentation, diagnostic approach and treatment modalities 12 patients ECS treated single tertiarycentre over 17-year period. Although...

Objective: Sclerosing Mucoepidermoid Carcinomas (SMEC) are low-grade malignant tumors with both mucinous and squamous differentiation representing less than 1% of thyroid malignancies. SMEC sometimes associated Hashimoto´s thyroiditis eosinophilia more common in females. In rare cases, they have showed a aggressive behavior local invasion the surrounding tissues, trachea, esophagus, or lymph nodes. Distant metastasis to lungs, liver, mediastinum, bone also been described. usually not...

The clinical characteristics of patients with postoperative hypoparathyroidism who recover parathyroid function more than 12 months after surgery have not been studied. We aimed to evaluate whether the intensity replacement therapy calcium and calcitriol is related late recovery function. compared demographic, surgical, pathological, analytical features two groups patients: cases, i. e., (those function>1 year thyroidectomy, n=40), controls, permanent (n=260). Replacement was evaluated at...

Abstract Ectopic differentiated thyroid carcinoma represents less than 1% of all cases, which usually arises along the cervical midline, and (delving into literature) there are scarce reports such entity in nuclear medicine imaging studies. We present a rare case confirmed synchronous, orthotopic, heterotopic (in lateral ectopic tissue) patient who was previously misdiagnosed as having paraganglioma, based on compatible clinical, analytical, imagenological (both structural functional) findings.
