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: 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...

Introduction: Intracranial Idiopathic Hypertension (IIH) is a rare complication of testosterone therapy. It is usually benign, but may result and permanent blindness. Its diagnosis is based on a high CSF (> 25 cm H2O) pressure, in the absence of specific causes. The androgen receptor is expressed in the human choroid plexus, and may enhance the activity of Na+/K+-ATPase, and therefore CSF secretion.Methods: Review of the patient’s cli...

Introduction: The 48XXXY karyotype is an infrequent (incidence about 1/50000 male births) sporadic aneuploidy of the sex chromosomes, classically considered as a variant of the Klinefelter syndrome (47XXY). Although many of their characteristics are shared, patients with the 48XXXY karyotype suffer from additional endocrinological and neuropsychological disturbances which are not part of the classic Klinefelter syndrome. Hereby we present a clinical case.<p class="abstext"...

Introduction: Oral semaglutide has been available in the Spanish market since November 2021. This new formulation has broken the self-injection barrier, and may enhance patient satisfaction.Methods: Retrospective review of the patients′ records and presential or telephonic interviews. All patients expressed their consent for the anonymous processing of their data. Numeric data are given as mean + s.d; paired t-test was used for comparison. Satisfac...

Introduction: Vitamin D deficiency is associated with higher risk of severe COVID-19, and type 2 diabetic patients are a vulnerable group. We described an alarming rate of vitamin D deficiency (around 80.0% with plasma calcifediol <30 ng/ml) in unsupplemented type 2 diabetes patients during the 2020 spring lockdown and the following winter in Northern Gran Canaria. There is an increasing awareness of this problem, both in family physicians and the general population, and t...

Introduction and Objective: Flash glucose monitoring is a form of interstitial glucose monitoring and it is indicated in patients with diabetes mellitus.The objetive of the study was to assess the effect of introducing flash glucose monitoring in adults with diabetes with respect to change in hemoglobin A1c (HbA1c).Material and methods: Prospective observational study of adults with diabetes in our center, in whom a prescription for a flash glucose monit...

Introduction: The development of immunotherapy has opened up a new approach in the management of different types of tumors that previously had not treatment, and its use is becoming increasingly widespread. Immunotherapy is based on blocking immune checkpoints involved in activating the immune response to malignant neoplasms. Since its introduction into clinical practice, several adverse effects related to the immune system have been reported. Among the endocrinological advers...

Introduction: During most of the autumn of 2022, the standard maintenance presentation of parenteral semaglutide (1.0 mg for weekly dosage) was temporarily unavailable. Many of the patients using this dose were switched to the standard maintenance dose of oral semaglutide (14 mg daily). The leaflet included with the product specifies that the 14 mg daily oral dose is equivalent to the 0.5 mg parenteral weekly dose, but this is most likely an interpolation, as there are no repo...

Introduction/Aim: New oral anticoagulant drugs such as the factor Xa inhibitor rivaroxaban are often preferred to the classic coumarins because they do not need frequent blood-test monitoring and have fever interactions with other drugs and foodstuffs. They are not, however, interaction free. Rivaroxaban is metabolized by oxidative degradation catalyzed by CYP3A4/5 and CYP2J2; it is also a substrate of the P-gp and ABCG2 efflux transporter proteins. CYP3A4 activity enhancers s...
