Objectives: To evaluate the different insulin regimens and types of insulin used in our population of type 1 diabetes (DM1) patients in the last revision in our clinic.Method: A descriptive study was carried out in our population of 535 DM1 patients. They had their initial diagnosis between 1967 and 2014.Results: In our population, 47.3% were women and 52.3% were men. The mean age of our patients was 33.8 years (S.D....

Background: Type 2 DM and chronic renal disease CKD are conditions associated with severe hypertension, loss of the blood pressure circadian rhythm (CR) and sympathetic nervous system (SNS) hyperactivity, suggesting a deficient dopaminergic modulation that could be reversed with dopamine agonists such as bromocriptine (BEC).Objective: The objective of this study was to evaluate the effect of bromocriptine in the blood pressure CR in patients with type 2 ...

Background: The prolactin/vasoinhibin axis constitutes a novel endocrine axis in which the generation, secretion, and actions of the pituitary hormones prolactin and vasoinhibins are under control of the hypothalamus, the pituitary gland, and of regulators in the target tissue microenvironment. Vasoinhibins are generated in the pituitary gland and in multiple target tissues through proteolytic cleavage of prolactin; it is not known wether they are also produced in the circulat...

Introduction: Alterations in foetal growth lead to neonatal health risks and favour metabolic diseases during adult life. Therefore, the study of birth weight determination and its modifications is crucial for metabolic diseases prevention. Placental growth is a key factor in foetal growth. It has been suggested that insulin and the IGF system play an important role in foetal growth and placental development and function. Although, insulin and IGFs in the umbilical cord blood ...

Background: Recent studies have shown that the incidence of differentiated thyroid cancer (DTC) is increasing.Objective: Evaluate the incidence of DCT in a center of the south of Spain for the last 15 years and analyse the clinical and morphological factors related to DTC.Methods: We reviewed the series of patients undergoing thyroid surgery at our hospital over a 15-year period and identified patients with DTC. Patients were divid...

Thyrotropin-secreting pituitary tumors are <1% of pituitary adenomas. Clinical manifestations are similar to other forms of hyperthyroidism. Most of them are diagnosed as macroadenoma (microadenomas <10%).Case 1: A 48 years old woman with menopause presented 6 years ago, consulting in 2009 for weight loss and palpitations. She had elastic goiter and distal tremor. Blood test: TSH 8.66 μUI/ml (0.2–4.2), FT4 4.7 ng/dl (0.7&#150...

Methods: A prospective study in 35 patients hospitalized for AKI for two consecutive years was carried out. TFT (serum thyrotropin, TSH; free thyroxine, FT4; and total triiodothyronine, T3 concentrations) were measured in each patient on three occasions: at admission, at hospital discharge and at their first outpatient visit.Results: Total prevalence of alterations in TFT was 82.9% (n=29). Of those, euthyroid sick syndrome (E...

Introduction: The European Society of Endocrinology Clinical Practice Guideline defines follow-up recommendations for AI based on the 1 mg overnight dexamethasone suppression test and the presence of associated comorbidities. Follow-up is not recommended for AI presenting serum cortisol levels post dexamethasone ≤1.8 μg/dl neither those presenting serum cortisol levels post dexamethasone between 1.9–5 μg/dl (defined as ‘possible autonomous cortisol se...

Introduction: A two-step approach is usually used to diagnose GDM. At 24–28 weeks of pregnancy, a 50 g 1-hour glucose or O’Sullivan test is performed. If it is positive (≥140 mg/dl), it is followed by a 100 g-3 hours-Oral Glucose Tolerance Test (OGTT) which is considered positive if at least two or more values are ≥ of reference values (105-190-165-145 mg/dl). Despite it is not include in any clinical practice guideline, sometimes the 100 g OGTT is obviat...

Introduction: After menopause, an abrupt drop in estrogen levels happens, while ovary androgens secretion declines gradually with aging. This relative hyperandrogenism may lead to the development of hyperandrogenic symptoms. However, the development of marked hirsutism and/or symptoms/signs of virilization, make necessary a detailed study in order to rule out tumorous cause (from adrenal glands or ovaries).Case report: 58 years old woman with progressive...
