Selective adrenal venous sampling is not always useful in primary aldosteronism

Paja Miguel , Pena Borja , Calles Laura A , Moreno Cristina

Adrenal venous sampling (AVS) is regarded as the gold-standard for the study of lateralisation of primary aldosteronism (PA) after its biochemical diagnosis. After catheterisation of both adrenal veins, confirmed by ratio of cortisol concentration in each adrenal vein and peripheral vein (selectivity index (SI)), lateralization is accepted if aldosterone/cortisol (A/C) ratio between both adrenal veins is over 3–4 (lateralization index (LI)), particularly if non-dominant v...

Surgical correlation of thyroid nodules categorised as potential follicular neoplasms in core-needle biopsy (CNB)

Paja Miguel , Zabala Rosa , Corta Igone , Exposito Amaia , Calles Laura , Lizarraga Aitzol , Ugalde Aitziber

In our centre we use CNB for routine study of thyroid nodules since 2005. Four diagnostic categories for CNB’s results have been standardised: insufficient; benign; follicular proliferation (FOL), including follicular and oncocytic neoplasms; and malignant. Diagnosis of FOL was defined according to the presence of microfollicular patterned biopsies with scant or absent colloid, sometimes with minimal pleomorphism or discrete nuclear changes. This category could be equival...

Preoperative TSH value, does it predict the surgical findings in papillary thyroid cancer?

Paja Miguel , Ciriza Maite Perez de , Calles Laura , Etxeberria Eider , Oleaga Amelia , Lizarraga Aitzol

TSH level has been proposed as a thyroid malignancy predictor in nodular thyroid disease. In addition, several clinical studies have reported that higher preoperative serum TSH levels were associated with more advanced stages of differentiated thyroid cancer (DTC) at the time of diagnosis.Methods: We collected retrospectively preoperative serum TSH from patients diagnosed of papillary thyroid cancer (PTC) who had undergone total thyroidectomy during the ...

Incidental thyroid carcinomas in patients operated on for benign thyroid pathology, are there preoperative factors suggesting a higher risk?

Paja Miguel , Ugalde Aitziber , Barrios Borja , Oleaga Ameli , Calles Laura , Moreno Cristina , Ugarte Estibaliz , Oleaga Amelia

Introduction: The discovery of incidental thyroid carcinomas (ITC) in patients undergoing surgery for a benign disease range between 3 and 16% of cases. During years, patients with hyperthyroidism were considered protected by TSH suppression (TSH is well known factor that favors the development of thyroid cancer). Thyroid size might be a predictive factor due to the excess of thyroid tissue prone to mutations. The knowledge of determining factors foretelling the presence of un...

Paraganglioma (PG) and cyanotic congenital heart disease (CCHD): the role of tisular hypoxia

Oleaga Amelia , Goni Fernando , Paja Miguel , Ugarte Estibaliz , Moreno Cristina , Iglesias Natalia , Etxeberria Eider , Calles Laura , Dublang Maddalen , Zabalegui Alba

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...

Radiological study of clinically non-functioning pituitary macroadenomas: a single institutional experience

Moreno Cristina , Paja Miguel , Lizarraga Aitzol , Etxeberria Eider , Arrizabalaga Cristina , Ugarte Estibaliz , Izuzquiza Ana , Goni Fernando , Iglesias Natalia , Calles Laura

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...

Cytological variants of papillary thyroid carcinoma: clinical presentations according with the presence of BRAF mutation

Oleaga Amelia , Etxeberria Eider , Calles Laura , Goni Fernando , Fuertes Elena , de Ciriza Maite Perez , Ugalde Aitziber , Paja Miguel

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...

Predictive factors of postoperative hypoparathyroidism after total thyroidectomy

Paja Miguel , Etxeberria Eider , Calles Laura , Exposito Amaia , Ugarte Estibaliz , Moreno Cristina , Lizarraga Aitzol , Espiga Javier , Oleaga Amelia

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...

Diagnostic and treatment delay in primary hyperparathyroidism (phpt): a pending issue

Paja Miguel , Martinez Adela L , Monzon Andoni , Arrizabalaga Cristina , Zabalegui Alba , Iglesias Natalia C , Calles Laura A , Etxeberria Eider M , Gutierrez Teresa

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...

Radiofrequency ablation in the treatment of benign thyroid nodules: a good alternative to surgery

Moreno Cristina , Paja Miguel , Izuzquiza Ana , Espiga Javier , Arrizabalaga Cristina , Martinez Adela Leyre , Monzon Andoni , Zabala Rosa , Iglesias Natalia , Calles Laura

Introduction: To date, benign thyroid nodules complainig of symptomatic or cosmetic problems and autonomous functioning thyroid nodules (AFTN) have generally been treated with surgery or I131. Radiofrequency ablation (RFA) is a novel technique that has demonstrated safety and efficacy in the treatment of these nodules. We describe the clinical experience at our hospital.Material and method: We include 33 patients (28 women, 5 men) from January 2013 to Se...
