Introduction: Hyponatremia is the most common electrolyte imbalance among hospitalised patients. Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is considered the most frequent etiology on patients with euvolemic hiponatremia. Conventional treatment includes water restriction and salt tablets with limited efficacy and very slow onset of action in certain patients.Material and methods: Systematic sampling of all SIADH patients treated wit...

Introduction: Interferon treatment for hepatitis C has been associated with Graves’-like thyroiditis, developing in rare instances severe ophthalmopathy. The usual management is interferon withdrawal and high-dose corticosteroids, but it may interfere with the resolution of hepatitis. Hereby we report a case successfully treated with radiotherapy, which in our knowledge has never been previously reported.Case report: A 52-year-old woman was diagnose...

Introduction: MicroRNAs (miRNAs) are short non-coding RNAs that regulate translation or degradation of target mRNAs. Therefore, miRNAs control gene expression in many biological processes, including proliferation, apoptosis, and differentiation. Deregulation of miRNAs expression is an important contributor to tumour development and progression. Even though several genetic and epigenetic lesions have been identified in human thyroid cancer, particularly in the papillary histoty...

Objectives: Prognosis of differentiated thyroid carcinoma (DTC) is usually good, but even so a proportion of the patients develop recurrences and eventually die of the disease. The aim of this study was to analyze the clinical and histopathological features of patients with DTC in our center and to identify prognostic factors in this group of patients.Patients and methods: We reviewed, retrospectively, 213 patients (184 females and 29 males, mean age 48....

Introduction: Non-classical congenital adrenal hyperplasia (NCCAH) due to 21-hydroxylase deficiency is one of the most frequent autosomal recessive diseases. Genetic analysis performed for genetic counselling revealed a miscorrelation with the clinical diagnosis in several patients at our centre.Aim: Confirm the genetic diagnosis of NCCAH in women attended for this condition.Materials and methods: Consecutive patients attended at o...

Introduction: Cinacalcet is an oral calcimimetic indicated in treatment of primary hyperparathyroidism if patients do not accept surgery, do not carry out the surgical criteria, there is failure of previous surgery or serious comorbidity that makes surgery impossible.Methods: Descriptive study that included 20 patients with primary hyperparathyroidism who had complete at least 12 months of treatment with cinacalcet for different reasons (eight patients r...

Reduced expression or activity of the thyroid hormone receptors (TRs) are common events in cancer, suggesting that these receptors could act as tumor suppressors. We have previously shown that TRβ expression in SK-hep1 hepatocarcinoma cells (SK-TRβ cells), reduces tumor growth and strikingly inhibits invasion, extravasation, and metastasis formation in nude mice. These effects could be related to a decreased expression in these cells of prometastatic genes, such as C...

Case of 33 years old male patient with an unremarkable past medical history, who after a car accident, a cystic nodular right neck mass was incidentally found by MRI of cervical spine. Physical examination revealed a mildly tender right neck mass. He was clinically and biochemically euthyroid. Denied history of neck irradiation. No family history of thyroid disease or thyroid cancer. Excisional biopsy of right neck mass showed metastasic well differentiated papillary carcinoma...

In the normal adrenal gland, serotonin (5-HT) stimulates cortisol secretion through activation of 5-HT4 receptors whereas, in some macronodular adrenal hyperplasia tissues, the corticotropic effect of 5-HT is mediated by ectopic 5-HT7 receptors. The aim of the present study was to investigate the role of 5-HT in the control of cortisol secretion in PPNAD tissues from 12 patients by using molecular, immunohistochemical and pharmacological approaches. RT-PCR studies revealed ove...

Introduction: Cinacalcet is an oral calcimimetic indicated in treatment of primary hyperparathyroidism if patients do not accept surgery, do not carry out the surgical criteria, there is failure of previous surgery or serious comorbidity that makes surgery impossible.Methods: Descriptive study that included 34 patients with primary hyperparathyroidism treated with cinacalcet. We recorded clinical and biochemical data before and after 6 months of treateme...
