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...

In our centre, thyroid core-biopsy (CB) has replaced fine needle aspiration biopsy (FNAB) in the study of thyroid nodules because its better accuracy. International guidelines recommend repeating the FNA in cases of inadequate or insufficient first specimen, but nothing is published about the case in failed CB.Objective: To study the differences between nodules with inadequate and diagnostic thyroid Core Biopsy and the accuracy of repeating a CB after a ...

The clinical significance and potential morbidity of papillary thyroid microcarcinomas (PTMC) is discussed. Particularly the differences between those PTMC identified postoperatively in histological examination (incidentals), and those diagnosed preoperatively (non-incidentals). We retrospectively analysed differences in clinical presentation and course after treatment in these two groups. The study population consisted of 199 patients with PTMC who underwent surgery from 2000...

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: Hypoparathyroidism (hypoPT) is the most frequent complication after thyroid surgery, usually as transient hypocalcaemia. Permanent parathyroid lesion is less frequent, but it can extend hospital stay and complicate postoperative management. Several preoperative factors predicting the development of hypoPT have been identified, including advanced age, hyperthyroidism, surgical experience and others. We evaluate the role of some potentially predictive factors in ou...

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 ...

Fine-needle aspiration cytology (FNAC) remains the mainstay in the study of thyroid nodules, with cytologic adequate specimens in almost 85% of cases in expert hands. Apart from the limitation of inadequate samples, there are false negative diagnoses in some cases, particularly in larger (>3 cm) nodules. Considering this, Large-needle biopsy (LNB) could be useful to improve diagnostic precision. We review the pathology reports (PR) of more than 100 patients operated since ...

Background: PHPT is the leading cause of hypercalcemia in outpatients. Its clinical presentation varies from asymptomatic forms to renal or bone complications. The only curative treatment is surgical resection, and delayed diagnosis can lead to serious morbidity.Objective: Identify the presence of PHPT at least one year prior to referral to endocrinology consultation. Secondly, determine whether diagnostic delay leads to increased complications.<p cl...

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...
