We describe the clinical case of two childbearing age women with thyroid dysfunction, hypocalcemia, hyperphosphatemia, and high levels of PTH.Case 1: A 34-year-old woman with infertility for 3 years, microprolactinoma treated with low-dose dopamine agonists, autoimmune primary hypothyroidism and obesity. She had irregular menstrual cycles and fatigue. Weight 130 kg, height 155 cm, cervical acanthosis nigricans and round face. Calcium 6.6 mg/dl, phosphoro...

Objective: To evaluate the response to treatment with insulin infusion pumps by the evolution of HbA1c over 8 years of experience.Methods: Observational retrospective study. We evaluated the response to treatment in 122 patients with type 1 diabetes recruited between 2004 and 2012 in our area.Results: Between 2004 and 2012, 122 pumps have been implemented (average of 17.4 pumps/year). The number decreased to only four in 2012. Pres...

Introduction: Everolimus is a drug selective inhibitor of mTOR. In 2012 a Phase 2 study* of everolimus monotherapy demonstrated modest efficacy in patients with pheochromocytomas/paragangliomas. Our objective was to evaluate the efficacy and safety of everolimus in a patient with paraganglioma. (*Phase 2 study of everolimus monotherapy in patient with nonfunctioning neuroendocrine tumor or pheochromocytomas/paraglangliomas. Do-Young Oh et al. Cancer 2012 <str...

Background: Data on sexual dysfunction (SD) in cirrhotic patients are limited. Our aim was to evaluate the sexual function of patients with end-stage liver disease and to compare it with the results after liver transplant (LT) and with that of a controlled group matched by age and gender.Methods: Changes in sexual functioning questionnaire were used to evaluate SD in cirrhotic patients awaiting LT and in the post-LT setting 1 year after transplant. Clini...

Transforming growth factor beta (TGFβ), which plays a key role in cancer and fibrotic disorders, mediates its actions mainly through activation of Smad transcription factors, which bind to Smad Binding Elements (SBEs) in target genes. We have previously observed that the thyroid hormone T3 blocks transactivation of SBE-containing reporter plasmids by TGFβ, and represses transcription of endogenous TGFβ target genes. We have now analysed the thyroid ho...

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: The National Osteoporosis Guideline Group (NOGG) recommends determine BMD in patients who present an intermediate risk of osteoporotic fracture using the FRAX® tool, follow-up for low risk, and treatment for high risk. In 2011, 3163 BMD were performed in the Complejo Asistencial Universitario de León (CAULE). Since the cost for each BMD is 58.6* (BOCYL 31/01/2011), annual spending could rise to *185 352. The aim was to assess whether fracture risk calcu...

Introduction: Different studies have published that testosterone therapy in men and women results in decreased HDL cholesterol and increased LDL cholesterol, and therefore an increased cardiovascular risk.Aims: To determine whether testosterone therapy has this effect on lipid parameters and markers of metabolic syndrome (MetSyn) in female-to-male transsexuals (FMT).Material and methods: We studied 50 FMT, aged 27.8±7.6 years,...

Aim: To assess ET1 levels in diabetic patients with and without microangiopathy, and compared with normal subjects, nondiabetic, without underlying vascular pathology.Introduction: The pathophysiology of diabetic microangiopathy is complex and many important aspects of it still are not fully understood. Endothelial dysfunction is of major importance in the pathogenesis of atherosclerosis and diabetic angiopathy. ET-1 is one of the most potent vasoconstri...

Objective: To analyze the impact of a specialized management on cardiovascular risk at the onset of type 2 diabetes mellitus.Material and method: Were analyzed 171 patients who visited our diabetes day hospital (DDH) during 2010–2011, studying the following variables: sex, age, BMI, smoking habit, arterial hypertension (de novo/previously known), antihypertensive therapy, dislypidemia (de novo/previously known), hypolipidemic thera...
