Introduction: Blood glucose control during pregnancy is essential in patients with gestational diabetes (GD) to prevent fetal complications. Despite advances in its control, neonatal morbidity and mortality still appears in a significant percentage of cases. The presence of GD also implies consequences for the mother, as the GD appearance in a new pregnancy and/or the future development of glucose metabolism alterations.Methods: We conducted a retrospect...

Introduction: Gestational diabetes (GD) is frequently associated with obesity and family history of diabetes. Besides these, other risks factors have been proposed, as previous GD, macrosomy or abnormal reproductive history.Methods: We conducted a retrospective comparative study including all patients diagnosed of GD during 1999 and 2008. The analyzed variables were incidence and risk factors of GD.Results: We included 384 patients...

Introduction: Salivary testosterone (Sal-T) reflects the plasma free testosterone fraction that can flow passively through the salivary glands and appears to be a strong correlation with the Calculated free testosterone (CFT) in both eugonadal and hypogonadal men. Since the collection of saliva is simple, noninvasive and inexpensive, the Sal-T is a promising tool for the screening of hypogonadism. Despite the initial interest that Sal-T has aroused, new clinical studies are ne...

Introduction: Free testosterone (FT) and bioavailable testosterone (BT), are better surrogate markers of the androgenic status of the individual than total testosterone (TT). Calculated FT (CFT) and calculated BT (CBT) which take into consideration the kinetics of the bond between FT and albumin and SHBG, provide results practically identical to those of the reference techniques. Salivary testosterone (Sal-T) is a promising tool in the study of gonadal pathology. The interassa...

The hypothalamic peptide, nesfatin-1, derived from the precursor NEFA/nucleobindin2 (NUCB2), was recently identified as central anorexigenic molecule, acting in a leptin-independent manner. Yet, its potential involvement in the regulation of other biological functions gated by body energy status remains unexplored. We show herein that NUCB2/nesfatin-1 is involved in the control of female puberty. NUCB2/nesfatin mRNA and protein were detected at the hypothalamus of pubertal fem...

Context: The determination of human chorionic gonadotropin (hCG) in cerebrospinal fluid (CSF) is useful for the differential diagnosis of suprasellar lesions. However, the concentrations that prove diagnostic for neurohypophyseal germinoma have not been well defined. In addition, the immunoassays used for such determination are the same as those applied in serum, and few studies have been performed regarding the validation of such techniques in CSF.Objec...

Background: HIV-associated hypogonadism is a prevalent endocrine disorder, total testosterone (TT) test is not useful for its diagnosis, Endocrine Society clinical practice guidelines have recently proposed calculated free testosterone (FT) as screening test of hypogonadism in HIV infected men, but no clinical study has been published using this approach in HIV population to date. Our aim was to study prevalence and risk factors for hypogonadism in HIV-infected men using FT.</...

Background: Classic 21-hydroxylase deficiency, due to severe mutations in CYP21B gene, is an uncommon disease (1/ 150 000). Salt-wasting form accounts for 75% of the cases and turns up with gluco- and mineralocorticoid deficiency as well as feminine hermaphroditism. Although wide psycho-social repercussion especially in women is known, the rarity of the disease and losses in follow-up may lead to a scarce clinical experience. We present 3 adult patients with CAH- SW followed r...

Introduction: In primary hyperparathyroidism (PHPT) medical treatment is indicated if the patient donot carry out the surgical criterion, donot accept surgery or there is another serious comorbidity that makes impossible the intervention. Cinacalcet is a calcimimetic that increase the sensitivity of the calcium-sensing receptor (CaSR) to ionized serum calcium, decreasing secretion of PTH and serum calcium concentration. This drug is prescribed for secondary hyperparathyroidism...

Despite advances in the management of last years, diabetes and its complications are still the most frequent cause of admission in Endocrine Departments. Nowadays, in our Hospital, 60% of admissions are due to Diabetes, and more than a half of these are diabetic ketoacidosis (DKA) (35.4%).Objective: Analize DKA episodes in our medical area in the last 12 years and compare them divided in two periods.Methods: Divide DKA episodes in ...
