Immunohistochemistry as alternative to DNA sequencing in detection of BRAF V600E mutation in papillary thyroid carcinomas

Paja Miguel , Del Cura Jose L , de Ciriza Maite Perez , Oleaga Amelia , Ugalde Aitziber

Objective: To compare the results of immunohistochemistry (IHC) and DNA sequencing in detection of BRAF V600E mutation in papillary thyroid carcinomas (PTC). BRAF V600E mutation is the most common genetic alteration in papillary thyroid carcinomas and is associated with worse prognosis. Direct sequencing is usually performed, but less expensive immunohistochemistry can be used instead.Methods: Study was performed in 54 consecutive PTCs during 2014–2...

Modelling the salivary cortisone to serum cortisol inter-relationship to predict serum cortisol under physiological conditions and after hydrocortisone

Debono Miguel , Harrison Robert , Keevil Brian , Whitaker Martin , Digweed Dena , Arlt Wiebke , Ross Richard

Introduction: Measuring serum cortisol to evaluate the normal circadian rhythm and adequacy of hydrocortisone replacement levels requires multiple readings; an expensive, cumbersome process. Conversely, salivary cortisone, a surrogate marker for free cortisol levels is non-invasive and well suited for out-patient settings. We hypothesised that salivary cortisone predicts circulating cortisol levels and can be used as an alternative marker of serum cortisol in a physiological s...

Recalcitrant hypocalcaemia in a patient with post-thyroidectomy hypoparathyroidism and roux-en-y gastric bypass

Miguel Gonzalo Allo , Fernandez Elena Garcia , Librizzi Soledad , Diaz-Guerra Guillermo Martinez , Carranza Federico Hawkins

Introduction: Roux-en-Y gastric bypass (RYGB) places patients at an increased risk of hypocalcemia due to the reduction in calcium absorption (because the procedure bypasses the duodenum and jejunum) and vitamin D deficiency. Subsequent thyroid surgery increases the risk of severe hypocalcemia due to potential post-operative hypoparathyroidism. Only a few cases have been published before of this kind of treatment-challenging hypocalcaemia.Case report: We...

Bone mineral density evolution after parathyroidectomy in patients with primary hyperparathyroidism

Vicuna Alicia , Ramos-Levi Ana , Sampedro-Nunez Miguel , Campos Sandra , Zelada Magaly , Marazuela Monica

Introduction: Primary hyperparathyroidism results in increased bone resorption. The presence of osteoporosis is at present an established surgery criteria.Objective: The aim of this study was to evaluate the changes in bone mineral density (BMD) after surgery in patients with primary hyperparathyroidism.Material and methods: Retrospective study of 58 patients with primary hyperparathyroidism treated by parathyroidectomy from 2004 t...

Association between peripheral vascular disease and other macrovascular and microvascular complications in diabetic patients

Miguel Gonzalo Allo , Fernandez Elena Garcia , Bracamonte Milagros Sierra , Diaz-Guerra Guillermo Martinez , Carranza Federico Hawkins

Introduction: Diabetes mellitus is a condition on the increase, carrying a high risk of macro and microvascular disease. Previous studies suggest a link between microvascular and macrovascular complications in diabetes. However, just a few studies have investigated whether the presence of peripheral vascular disease (PVD) is associated with other macrovascular and microvascular complications in diabetes patients. So, this was the aim of our study.Patient...

Diabetic kidney disease and its association with macrovascular disease in diabetic patients

Fernandez Elena Garcia , Miguel Gonzalo Allo , Villa Lucas Arroyave , Diaz-Guerra Guillermo Martinez , Carranza Federico Hawkins

Introduction: It is well known that diabetes confers a substantial burden of macrovascular disease. However, just a few studies have investigated the association between diabetic kidney disease (DKD) and cardiovascular disease. The purpose of this study is to investigate whether the presence of DKD is associated with macrovascular disease in diabetic patients.Patients and methods: 98 diabetic patients (48 males/50 females) were included in the study. DKD...

Giant prolactinoma: a current challenge

Goncalves Ana Pires , Clara Ana Rita , Lourenco Artur , Cordeiro Miguel , Almeida Rui , Lazaro Mario

Introduction: Giant prolactinomas are rare tumours, representing 2–3% of all prolactin (PRL)-secreting tumours. Their definition is restricted to pituitary adenomas with a diameter ≥4 or ≥2 cm of suprasellar extension, very high PRL concentrations (≥1000 ng/ml) and no concomitant GH or ACTH secretion. They are more common in young to middle-aged men. Endocrine symptoms are often present for a long period of time, but most times the diagnosis is made when...

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...

Familial hypocalciuric hypercalcemia: an important differential diagnosis from hyperparathyroidism

Luque-Fernandez Ines , Vicente Almudena , Luque Alessandra , Del Val Florentino , Garin Intza , Morlan Miguel Angel

Introduction: Familial hypocalciuric hypercalcemia (FHH) is a rare, benign, autosomal dominant condition usually caused by heterozygous inactivating mutations in the gene encoding the calcium sensing receptor (CASR).Case: 22-year-old woman referred to endocrinology for suspected polycystic ovary syndrome. Hypercalcemia is detected. Laboratory tests showed persistent hypercalcemia with a serum total calcium of 11.1 mg/dl (8.8–10.2), phosphorus 2.8, i...

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 ...
