Introduction: Recent studies point to an ever increasing papillary thyroid microcarcinoma (PTMC) prevalence, with a percentage range between 20 and 43% of all differentiated thyroid carcinomas. It is many times considered an ‘incidental’ finding and its clinical behaviour is uncertain.Aims: To characterize a cohort of patients with PTMC, with reference to clinical and pathological variables and outcome.Methods: Data from ...

The use of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG–PET) has increased the detection of thyroid incidentalomas (TI). These are associated with a risk of malignancy between 25 and 50%. Some studies show an association between SUVmax uptake and malignancy.The objective of this study was to determine the prevalence of malignancy on 18F-FDG–PET positive thyroid nodules and to evaluate the relatio...

Introduction: Blastocystissp. (BS) is the most common intestinal parasite that is isolated in human fecal samples. Its pathogenic role is still questioned. While some consider it a beneficial component of the human intestinal microbiota, some evidence relates it with dysbiosis and development of metabolic syndrome (MS). Its presence has been inversely correlated with BMI.Objective: The objective of this study is two-fold: determining the prevale...

Giant prolactinomas are tumors with a large size >4 cm and/or prolactin levels higher than 3000 ng/ml and/or highly invasive growth. Today dopamine agonists (DA), mainly cabergoline (CAB), are the first-line choice in the treatment of these tumorsTo assess the efficacy, safety and long-term follow-up of patients with giant prolactinomas treated with DA. We retrospectively reviewed the clinical records of 33 patients with giant prolactinomas. Mea...

Introduction: Ectopic Cushing Syndrome (ECS) is a rare disease associated with significant comorbidity. Among the causes of Cushing’s syndrome (CS), ACTH-producing extrahypophyseal tumours are rarely reported. The aim of our study is to describe the clinical, diagnostic and therapeutic characteristics of patients with ECS treated in our Endocrinology department over a 15-year period.Methods: A cross-sectional unicentric retrospective study was desi...

Transforming growth factor β1 has a critical role in the regulation of testicular function. Transgenic male mice over expressing α and β subunits of hCG (hCG+) are infertile and testicular steroidogenesis is enhanced showing high levels of testosterone and progesterone (P4). The chronic hCG hyperstimulation leads to Leydig cell (LC) hypertrophy/hyperplasia in prepubertal mice.Aims: To analyze: i) the expression of the TGF-β...

Undifferentiated thyroid carcinoma is a highly aggressive human cancer with poor prognosis. A strong association has been observed between undifferentiated thyroid carcinoma and TP53 mutations. Plitidepsin (AplidinTM) a novel anticancer compound from a sea tunicate, has been reported to induce apoptosis independently of TP53 status. We investigated the actions of plitidepsin in human thyroid cancer cells. initiallyexperiments using primary cultured cells from a d...

Introduction: Neurofibromatosis type 1 (NF1) is an autosomal dominant condition with an incidence of 1 in 2600 to 3000 individuals. Patients with this disorder are characterized by multiple neurofibromas, caf-au-lait macules, axillary freckling, optic gliomas, iris hamartomas, and skeletal abnormalities. Overall risk of developing neoplasms is approximately 2 to 4-fold higher in patients with NF1, with a risk of malignancy estimated between 5 and 15%. Endocrinopathies are some...

Introduction: Thyroid cancer is the most frequent malignant endocrine neoplasia. Its incidence has significantly risen worldwide in the last decades.Objective: To estimate the incidence of thyroid cancer in Valladolid’s east area population, Spain, over the period 2002–2016.Methods: A retrospective descriptive research was performed in the Clinical Universitary Hospital of Valladolid (HCUVa). Clinical data was obtained fr...

Pheochromocytoma (PCC) is a rare tumor that arises from the adrenal medulla, usually presents with headache, sweating and palpitations due to excessive catecholamine release. However, PCC may secrete neuropeptides, hormones and cytokines, such as interleukin-6 (IL-6)) resulting in unusual clinical manifestations. A 48-year-old woman with a previous history of type 1 neurofibromatosis (NF1) and hypertension was referred to discarded PCC. Laboratory tests revealed leukocytosis a...
