Introduction: Pseudohypoparathyroidism type la (PHP-1a) is an uncommon disorder that results from an inactivating mutation in the GNAS gene. It can present with resistance to several hormones, in addition to parathyroid hormone (PTH). A characteristic skeletal phenotype also results, referred to as Albright’s hereditary osteodystrophy, that occurs because of the crucial role of Gs-α signaling in the growth, differentiation, and structure of these tissues.<p class...

Introduction: Cushing’s syndrome results from increased or aberrant expression of ACTH, CHR, or neuroendocrine receptors that leads to uncontrolled hypersecretion of cortisol. The most common cause is ACTH-secreting pituitary adenomas. Alternatively, the glucocorticoid excess may be due to adrenal neoplasia or to ectopic ACTH – secreting tumors. There are rare reports of patients with a meningioma secreting CRH presenting paraneoplasic Cushing’s syndrome.<p ...

Introduction: Primary hyperaldosteronism is a known cause of arterial hypertension, classically with hypokalaemia. About 30–40% of the cases are caused by unilateral aldosterone-producing adenoma, and the recommended treatment is adrenalectomy. Hypoaldestoronism is an uncommon complication of unilateral adrenalectomy, but it can be life-threatening. We present a case of severe hypoaldosteronism after unilateral adrenalectomy for the treatment of primary aldosteronism....

Diabetic ketoacidosis (DK) is one of the most serious complications of diabetes mellitus (DM). We performed a case review of DK patients admitted to the intensive care unit (ICU) of our Hospital between 1 June 2012 and 30 June 2016. A demographic analysis was made, time of DM evolution, the therapy and the factors that led to its decompensation. Thus, a total of 42 DK patients were admitted to the ICU in the referred period, mean age was 45 years, a clear predominance of femal...

Diabetic ketoacidosis (DKA) is one of the most serious complications of diabetes mellitus (DM). We describe 2 cases of type-2 diabetic patients admitted by a surgical reason/trauma in which DM control was neglected. We present a 74-year-old patient with poor metabolic control (HbA1c 7,6%) treated with metphormin, sitagliptin and glibenclamide, admitted for orthopaedic surgery. During hospitalization, there were noted several episodes of disorientation with hyperglycae...

Aim: To analyze the effects of inositol administration on parameters related to glucose homeostasis.Material and methods: Systematic review and meta-analysis of articles published in Medline or Web of Science Until February 1, 2016. We included studies that met the following criteria: i) Randomized controlled clinical trials of inositol/inositol isomer supplementation against placebo in parallel design, ii) performed in humans, iii) with information abou...

Introduction: Sheehan syndrome (SS) is caused by postpartum necrosis of the pituitary gland, associated with significant haemorrhage during or after delivery. It is rare in developed countries, but still frequent in underdeveloped ones. We present a rare presentation of this syndrome.Clinical case: A 48 years old black woman presented at the emergency department for long term fatigue and dyspnea that worsened a few days before. Her physical examination r...

Introduction: Chronic somatotropin (ST) hypersecretion has systemic effects. It can cause important structural and functional cardiovascular (CV) changes, which can result in increased morbidity and mortality.Case report: A 48-year-old, male. followed by cardiology since 2005 for dilated cardiomyopathy (DCM) (Ecocardiography: moderately dilated left ventricle with globular appearance. Severely impaired global systolic function - LVEF 25%. Right cavities ...

Transthyretin (TTR) is a protein mainly synthesized by the liver and choroid plexus (CP) of the brain. Besides its role as a carrier for thyroid hormones, TTR also sequesters the amyloid beta (Aβ) peptide impairing its deposition in nervous tissues, and its concentrations in the cerebrospinal fluid (CSF) appear to be inversely correlated with Alzheimer’s disease (AD) onset and progression. Abundant evidence suggests that the depletion of progesterone (PROG) at menopa...

Background: Distal symmetric polyneuropathy (DSPN) is one of the most prevalent chronic complications of diabetes and the most common cause in the pathway to diabetic foot ulceration. Screening for DSPN enables early intervention and prevention of complications. The Semmes-Weinstein Monofilament Examination (SWME) is currently the method of choice to screen DSPN, but ideally two neurologic tests should be used. The Michigan Neuropathy Screening Instrument (MNSI), which evaluat...
