Aim: Radioiodine activities for the treatment of Graves’ disease hyperthyroidism are still subject to discussion, as is the use of a fixed approach over a dosimetric one. We aimed to evaluate our success rate using a personalized dosimetric approach: instead of the “(MBq I-131×g gland mass×100)/(percentage uptake at 24 h)” activity calculation, we further adjusted for factors such as gender, age, diagnosis, 2 h and 4 h radioiodine uptake, previous medi...

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...

Macroprolactin interference is a common problem in the interpretation of immunoassays for prolactin. Identifying macroprolactinemia can prevent errors in diagnosis and subsequent delivery of treatment to patients. The search for macroprolactin through polyethylene glycol (PEG) precipitation followed by percentage recovery is the most common used method in clinical laboratories. This study aimed to evaluate the implementation of macroprolactin assessment in hyperprolactinemic s...

Cushing’s Syndrome (CS) is an uncommon disease worldwide, being characterized by an increased production of glucocorticoids, and if left untreated can lead to serious consequences and women with CS rarely get pregnant. The aim of our work is to make a systematic review of the cases of pregnancy in patients with previously diagnosed CS, being performed an extensive research of the Medline and Web of Knowledge databases, and add three new cases observed in our institution. ...

Background: Maturity onset diabetes of the young (MODY) has an estimated prevalence of 1–5% in the diabetic population, but misdiagnosis as type 1 or type 2 diabetes is common. It comprises a heterogeneous group of monogenic diseases characterized by primary dysfunction of β cell, young onset, autosomal dominant inheritance, without autoimmunity and without ketosis. Early diagnosis remains a challenge with important future implications, since it allows treatment opti...

Introduction: Thyrotoxicosis after total thyroidectomy (TT) is mostly iatrogenic. Rarely, an hyperfunctional thyroid remnant or ectopic tissue may be the cause. We report a case of Graves’s disease in a mediastinal thyroid mass presenting 7 years after TT for nontoxic goitre.Case report: A 67-year-old woman presented with palpitations, fatigue and weight loss. She had a history of TT for nontoxic multinodular goitre at the age of 60 without any sign...

Studies have demonstrated the presence of androgen receptors in osteoblasts and osteocytes, confirming that androgens are important for the maintenance of bone in men. Additionally to steroid hormones, histamine stimulates osteoclast differentiation and survival and plays a role in the inflammatory response via H2 receptors. We purposed to investigate whether cimetidine, an histamine H2 receptors antagonist and antiandrogenic drug, interferes in the periodontal tissue damages ...

Introduction: Neonatal diabetes is a rare condition diagnosed within the first months of life. Activating mutation of KCNJ11, the gene encoding the Ki6.2 subunit of the ATP-sensitive potassium channel, is the most common cause of permanent neonatal diabetes, and ~20% of patients have neurological features.Patients with the severe neurological phenotype exhibit developmental delay, motor weakness, and epilepsy in addition to diabetes (DEND syndrome). Inte...

Background: Visceral obesity has been associated with systemic oxidative stress, measured by oxidized LDL (oxLDL).Aim: Investigate circulating oxLDL levels in patients with visceral obesity, and its relationship with metabolic abnormalities found in visceral obesity.Methods: We evaluated blood pressure (BP), waist circumference (WC), fasting glucose, total cholesterol, LDL, HDL, triglycerides, ApoA1, ApoB, ApoCIII, Lp(a) and oxLDL ...
