Introduction: In most patients with familial history of pheochromocytoma/paraganglioma, leads in the majorty of cases to a postive genetic testing for mutations, and what’s more in those patients with no familial antecedents, about 10–25% carry a mutation in one related gene. In these cases other aspects like, bilaterality, multiplicity or location must be taken into account.Objective: The objective of the study was to discuss the importance of...

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: The most frequent causes of hypercalcemia in the general population are primary hyperparathyroidism and malignancies. However, we must sometimes consider other causes, such as Cushing’s syndrome.Clinical case: A 49-year-old man who was being assessed for hypertrophic cardiomyopathy was referred to our Endocrinology Clinic in order to investigate the incidental finding of hypercalcemia (11.08 mg/dl) with high PTH (84.6 pg/ml), hypophosp...

Objectives: Main: To assess the effect on the 10-year risk of cardiovascular events (RCVE) of daily supplementation with a fixed combination of red yeast rice extract (250 mg), berberin 525 mg and coenzyme Q10 (50 mg) in patients with self-reported statin intolerance. Secondary: effects on anthropometric (BMI, SBP, DBP, HR) and laboratory (lipids, fasting glucose and HbA1C in diabetic patients, eGFR, AST, ALT, GGT, CK); self-reported compliance and tolera...

Background: Retrospective, transversal and analytical study was designed to determine the relationship between ApoB/ApoA1 ratio, Non-HDL-Cholesterol/HDL-Cholesterol ratio and Metabolic Syndrome (MetS) in type 2 diabetes mellitus (T2DM) patients attending routine follow-up in outpatient clinic from Madrid.Methods: The study was performed at the University Hospital Infanta Leonor, a public health center, and specialized secondary referal, which provides se...

Introduction: Prolactinomas are the most common tumors among functional pituitary adenomas and they constitute 40% of all pituitary tumors. Dopamine agonists (DA) are considered the primary treatment of prolactinoma. DA can lead to complete remission (including eradicacion of the tumor), allowing discotinuation of treatment. So far, there aren’t clinical criteria with sufficient predictive value for long-term remission.Objective: To assess the effec...

Objective: The aim of this study is to evaluate clinical characteristics of patients diagnosed of follicular thyroid carcinoma and to study factors that are associated with a worse prognosis of the disease.Methods: We included 153 patients diagnosed of follicular thyroid carcinoma in our centre between January 1985 and December 2016. The baseline characteristics of the patients, and their long-term outcomes were collected. The mean follow-up was 15.2 yea...

Introduction: Fine needle aspiration biopsy (FNAB) is the mainstay diagnostic procedure for evaluation of thyroid nodules, but it doesn’t permit to distinguish between benign and malignant follicular lesions (category IV in the Bethesda Cytopathology System). Some reports have suggested an association between increased serum levels of TSH and thyroid cancer. However, the specific relationship between TSH and malignancy has been scarcely studied in follicu...

Introduction: The role of external beam radiotherapy (EBRT) as primary or as adjuvant therapy in the non-undifferentiated thyroid cancer (NUTC) is controversial. Most published data refer to retrospective case series. Therefore, little is known about the correlation between tumor markers and radiologic measurements of tumor response.Objectives: The study aimed to analyze the kinetics of tumor markers and radiologic measurement of tumor response after EBR...

In XLH, high circulating FGF23 causes hypophosphatemia, rickets, and short stature. In our Phase 2 study, 52 XLH children (ages 5–12 years, ≤Tanner 2) were randomized to receive KRN23 subcutaneously biweekly (Q2W) or monthly (Q4W). Serum phosphate (Pi) was measured biweekly. KRN23 dose was titrated (maximum 2 mg/kg) targeting age-appropriate serum Pi concentrations.The first 36 subjects had a mean 6.6 years of standard-of-care treatment before...
