Introduction: Familial hypocalciuric hypercalcemia (FHH) is a rare condition (1–2% of causes for hypercalcemia) and may be confused with primary hyperparathyroidism. Diagnosis of FHH must be suspected in patients with a family history of chronic hypercalcemia, no symptoms and low urinary excretion. This disease is due to mutations in the calcium-sensing receptor (CASR) gene. Meningiomas are common intracranial tumors (15–20% of primary neoplasms of the central nervou...

Aim: To evaluate the long-term efficacy of percutaneous ethanol injection treatment (PEIT) as an alternative to thyroid surgery in symptomatic thyroid cysts with a structured protocol.Methods: Seventy five subjects (48±12 years; 58% women) with symptomatic benign thyroid cysts relapsed after drainage were included. PEIT was conducted using the established procedure in our hospital, and the initial cyst volume, pain perceived by the patient and sympt...

Introduction: Recent studies suggest that the use of dipeptidyl peptidase 4 inhibitors (DPP-4i) may be associated with an increased risk of developing bullous pemphigoid; which has led to publication of several pharmacovigilance alerts.Objectives: To characterize the potential association between the use of DPP-4i and the risk of developing bullous pemphigoid.Material & methods: Observational, retrospective study based on clini...

Introduction: The caloric expenditure and thermogenesis are very important aspects in the obesity problem, mostly underestimated. The ‘Protein Leverage Hypothesis’ (PLH) promotes the effect of satiety, delaying the hunger sensation; thus entails the regulation of caloric intake and body weight, as well as, the modification of thermogenic activity and energy expenditure. However, the effect of high protein diet over the physiological components of energy expenditure h...

Introduction: Vitamin D is a liposoluble molecule which takes part in calcium–phosphorous homeostasis of the human body. Its optimum levels according to SEIOMM range between 30 and 75 ng/ml. Being liposoluble substances they require the presence of biliar salts for their absorption; 80% is absorbed in the yeyune and in a lesser extent in the duodene. The correct concentration of vitamin D is of key significance in obesity, particularly its visceral type. An excessive body...

Backgrounds and aims: The aims of the study were, on the one hand, to analize the prevalence of type 2 diabetes mellitus in a population of institutionalized older people and, on the other hand, to evaluate if the anthropometric parameters and the prevalence of malnutrition and sarcopenia were different in diabetic patients compared with the group of non-diabetics.Methods and material: A total of 312 institutionalized elderly people volunteers with a mea...

Prenatal and postnatal environment can regulate gene expression through multiple epigenetic mechanisms, being DNA methylation among the most relevant. Metabolic and reproductive function may be modified by this mechanism. Sons born to women with PCOS show altered markers of metabolic and reproductive function during childhood and adulthood. However, these functions have not been studied during puberty. The aim of the present study was to assess the global methylation pattern a...

The sex-specific sex steroid profile seems to be associated to the gender differences between males and females on metabolic and cardiovascular risk (CVR). Objetive: to examine the effects of cross-gender sex steroid exposure on metabolic and CVR parameters. We incorporated 152 women transgender (WT), age (Median) 31 yr old (16–62) and 76 male transgender (MT) age: 25 yr old (17–53), treated at least by 1 year. WT received transdermal 17ßEstradiol (E2) 50 μ...

This study was conducted to evaluate the frequency of PCOS in a group of FTM transsexual persons and its relationship between clinical, hormonal and metabolic characteristics.Subjects and Methods: We studied 21 FTM cases, aged 17–37 years, BMI 24.6±5.2. No patient reported previous hormonal treatment or sex re-assignment surgery. PCOS was diagnosed according to the Rotterdam ESHRE/ASRM-sponsored PCOS Consensus Workshop Group, 2004. World Health...

The known functions of the thyroid hormones in the liver have expanded from their well-known roles in regulating metabolism to also participate in liver regeneration, senescence and hepatocarcinogenesis. The transcription factors STAT3 and NF-κB play a key role in liver homeostasis, in the response to infection and inflammation and in hepatocarcinoma development. Interleukin 6 (IL-6) and Tumour Necrosis α (TNFα) are the best-known cytokines responsible for hepat...
