Introduction: Routine central lymph node dissection (CLND) in papillary thyroid carcinoma (PTC) is controversial. Selective biopsy of the sentinel lymph node (SLN) could improve the surgical approach, as negative cases would benefit from avoiding a more aggressive technique and in positive samples a more accurate staging would be obtained.Aim: To analyze the usefulness of SLN biopsy in the surgical treatment of PTC.Patients and Met...

Objective: Calculation of accurate insulin boluses is one of the major problems related to intensive insulin regimens. A bolus calculator (BC) incorporated into the insulin pump estimates the dose of insulin to be administered at the meal and makes calculation easier and more precise.The aim of the present study was to assess the efficacy of a BC on glycaemic control of patients with DM1 on CSII.Material and methods: We enrolled 20...

Background: Endothelial dysfunction may have deleterious effect cardiovascular pathology in diabetic patients.Atrial natriuretic peptide (ANP) exerts beneficial effects on the cardiovascular system in part by exerting antioxidant activity. Recently it was reported that ANP is able to exert an antihypertrophic effect in myocitos at least in part due to inhibition of NADPH oxidase and superoxido generation.It seems that hyperglucemia...

A 16-years-old male, with familiar precedents of familiar macrocephaly, he has been visited in external consultations of digestive in 2008 because he had rectal bleedings. A colonoscopy was made two times, in those situations some intestinal polyps have been extirpated. The result of the pathological antomy was polyps ganglioneuromas.Due to the pathological compatible anatomy with ganglioneuromas, it stemmed to external consultations of endocrinology to ...

Hypersecretion of hCG in transgenic mice produces profound alterations in the ovary, thus triggering failures in ovulation and affecting fertility. The objective of this study was to analyze the response of immature female mice overexpressing moderated (hCGβ+; 0.1 IU/ml) and elevated (hCGαβ+; 7 IU/ml) levels of hCG to an ovulation induction protocol (PMSG 7.5 IU i.p.; after 48 h, hCG 7.5 IU i.p). Wild-type (WT) females subjected to the same protocol were used as...

Temozolomide, an alkylating agent used in malignant gliomas, has been recently used too in the treatment of aggressive pituitary tumors. To date, two cases of Nelson’s syndrome has successfully treated with 5 days of 28-day cycle, but the follow-up has been shorter than 12 months. We reported the third patient with Nelson’s syndrome treated with temozolomide, who after an initial goal response to three 300 mg 5 days of 28-day cycles shown a clinical and biochemical (...

Genes that encode neuropeptides can be recognized in the human genome because their products are (1) highly conserved across species, (2) trafficked though cells by secretory signal peptides and (3) susceptible to proteolytic cleavage at consensus sequences for processing to neuroactive products. One candidate gene is oesophageal cancer-related gene (ECRG4) which was first identified by screening for up- or down-regulated genes in oesophageal cancer. The product of ECRG4, whic...

It was reported that the inhibition of central nervous system (CNS) axon growth is mediated by Ca2+-dependent phosphorylation of epidermal growth factor receptor (pEGFR) and that local administration of small molecule EGFR antagonists to optic nerve lesions promoted retinal ganglion cell (RGC) axon regeneration (Koprivica et al. 2005). This result was attributed to suppression of EGFR kinase, which neutralised the axonal growth inhibitory potency of CNS myeli...

Objective: Anorexia nervosa (AN) is often associated with severe mineral bone loss and increased risk of fractures. The objective of this study was to assess the bone mineral density (BMD) in patients with AN and its relationship with different anthropometrics, clinical and hormonal parameters.Patients and methods: We evaluated 47 women with AN according to criteria of DSM-IV. The anthropometrics variables measured were: weight (kg) height (m), BMI (kg/m...

Background: Diabetes mellitus leads to endothelium dysfunction and an accelerated progression of atherosclerosis. Vascular complications of diabetes mellitus can affect not only large and medium arteries resulting in coronary heart disease and peripheral arteries diseases, but also small vessels leading to retinopathy and nephropathy.Endothelin-1 is mainly synthesized by the vascular endothelial cells and acts on the vascular smooth muscle. Because of it...
