Bilateral cervical exploration has been the gold standard in parathyroid surgery. Nowadays, the preoperative localization procedures have facilitated the minimally invasive surgery. This study aims to analyze the influence of thyroid disease in Tc99m-sestamibi scintigraphy (MIBI) results.A series of 154 patients with PHP who underwent parathyroidectomy was reviewed. Patients were divided into two groups: group 1 (G1, 58 patients) with thyroid diseases, a...

Surgery followed by 131I ablative therapy (IAT) is the usual treatment for patients with differentiated thyroid carcinoma (DTC). Thyroglobulin levels obtained 9–12 months after IAT under TSH stimulation (Tg2) is a very reliable marker for the presence of thyroid tissue. The value of stimulated thyroglobulin previous to ablation (Tg1) is more controversial. The aim of this study was to examine the relationship between Tg1 and Tg2.Material ...

Introduction: CCHD comprises a number of different congenital heart defects associated with elevated pulmonary artery pressure and pulmonary vascular resistance, resulting in a reversed or bidirectional shunt (Eisenmenger syndrome). These entities develop systemic hypoxia. Pheochromocytoma and paraganglioma (PHEO/PG) are neuroendocrine tumours. Several inheritance genetic alterations have been reported in PHEO/PG syndromes. A pathogenic association between these entities is pr...

Introduction: When facing with non-functioning pituitary macroadenomas (NFPMA), radiological invasion is determinant to surgical approach, apart from histological biomarkers of pituitary tumor aggressiveness (Ki-67; p53 and mitotic index). Invasive tumors usually need additional surgery and/or radiotherapy. There are no much studies describing epidemiological data on aggressive pituitary tumors in clinical practice. We provide information regarding the radiological findings of...

Introduction: BRAF(V600E) mutation has received great attention to improve risk stratification in patients with PTC. Its prognostic value in the different Cytological variants (CytV) of PTC is not well established. The aim of this study was to investigate differences in clinicopathological features according to CytV, among patients harbouring the mutation.Methods: We evaluated 102 patients with pathological diagnosis of PTC. All of them underwent total t...

Introduction: BRAF (V600E) mutation is the most frequent detected genetic change in papillary thyroid cancer (PTC) and its presence has been related to aggressive clinical and pathological features. Lymph node metastases (LNMx) are common in PTC and are associated with an increase in loco-regional recurrence. However, prophylactic lymph node dissection is not routinely performed because of high rate of surgery complications. Therefore, there is a need to find a good marker to ...

Introduction: Maternal clinical thyroid disorders can cause reproductive complications. However, the effects of mild thyroid dysfunction are controversial. The impact of SH and thyroid autoimmunity on miscarriages, obstetric and perinatal outcomes are not yet well established and the effect of levothyroxine replacement in pregnant women with SH is unclear. The aim of this study was to evaluate the impact of thyroid autoimmunity in early pregnancy on obstetric and perinatal out...

Introduction: BRAF (V600E) mutation is the most frequent detected genetic change in papillary thyroid cancer (PTC). Its presence has been related to aggressive clinical and pathological features. Therefore, BRAF mutation has drawn considerable interest as a potential prognostic factor for PTC. The presence of the mutation confers the tumour a disability to uptake RAI, diminishing the therapeutic tools. However if this feature is related to some kind of tumour dedifferentiation...

Introduction: Minimally invasive surgery has become the standard surgical procedure in Primary Hyperparathyroidism (PHP). Targeted parathyroidectomy is associated with a shorter operative duration, a lower risk of complications and a greater patient satisfaction. This approach is dependent on precise localization of the abnormal gland. 99mTc-sestamibi scintigraphy and ultrasonography are acceptable imaging modalities to detect parathyroid adenoma prior to operation but discrep...
