Leptin modulates Sertoli cells mitochondrial function and biogenesis with implications for the nutritional support of spermatogenesis

Moreira Bruno M , D Martins Ana , Monteiro Mariana P , Sousa Mario , Alves Marco G , Oliveira Pedro F

Current lifestyle, characterized by physical inactivity and a poor diet, is heavily linked with an increased incidence of metabolic diseases. One of the most serious silent co-morbidities of those diseases is infertility. The hormonal link between food intake and energy homeostasis is mediated by the leptin ghrelin axis. Compelling evidence suggests that direct leptin’s action regulates cellular glucose homeostasis and mitochondrial biogenesis. We have recently shown that...

Amiodarone and refractory thyrotoxicosis in a patient with complex arrhythmia

Cunha Nelson , Gomes Leonor , Martins Diana , Oliveira Diana , Lages Adriana , Ventura Mara , Fadiga Lucia , Catarino Diana , Carrilho Francisco

Background: Amiodarone is a potent antiarrhythmic drug used to treat tachyarrhythmias. However, is linked to a number of adverse effects, including thyroid dysfunction. It is the main cause of drug-induced thyrotoxicosis. Here we report a clinical case of amiodarone-induced thyrotoxicosis (AIT) in a patient with complex ventricular dysrhythmia.Case report: A 23 years-old women with dilated cardiomyopathy, severe depression of ejection fraction of left ve...

Massive bilateral pheocromocytomas – a rare case

Martins Diana , Rodrigues Dircea , Baptista Carla , Melo Miguel , Cardoso Luis , Vicente Nuno , Oliveira Diana , Ventura Mara , Lages Adriana , Carrilho Francisco

Introduction: Pheochromocytoma is a rare catecholamine-secreting tumor that arises from the chromaffin tissue of the adrenal medulla. Of the reported cases, only 10% consist in bilateral lesions and the probability of multiple endocrine neoplasia should always be investigated.Case report: Female patient, 19 years old, presented with a clinical history with 2 years of evolution, characterized by episodes of palpitations, headache and abdominal discomfort....

The effect of anorexia nervosa on bone

Vicente Nuno , Rodrigues Dircea , Barros Luisa , Guelho Daniela , Cardoso Luis , Oliveira Diana , Martins Diana , Ventura Mara , Lages Adriana , Carrilho Francisco

Introduction: One of the most common endocrine complications of anorexia nervosa (AN) is the decrease in bone mineral density. The authors evaluated the predictive factors of osteopenia and osteoporosis in AN patients admitted with low weight.Patients and methods: Retrospective analysis of 45 patients admitted with AN between 2001 and 2015 in the Endocrinology department, corresponding to 63 admissions. Bone mineral density was classified according to WH...

Addison disease in antiphospholipid syndrome – case report

Oliveira Diana , Paiva Sandra , Rodrigues Marcia , Guelho Daniela , Cardoso Luis , Vicente Nuno , Martins Diana , Lages Adriana , Ventura Mara , Carrilho Francisco

Introduction: Primary adrenal insufficiency or Addison disease (AD) is a potentially fatal condition if not diagnosed in time. Rarely, it can arise as a manifestation of antiphospholipid syndrome (APS), caused by adrenal venous thrombosis and consequent hemorrhagic infarction.Case report: We present the case of a 36-year-old caucasian woman with APS diagnosis since she was 24, with history of arterial hypertension and multiple thrombotic events (deep vei...

Continuous glucose monitoring for evaluation of glycemic variability after bariatric surgery

Martins Diana , Cardoso Luis , Baptista Carla , Rodrigues Dircea , Barros Luisa , Vicente Nuno , Oliveira Diana , Lages Adriana , Ventura Mara , Carrilho Francisco

Introduction: Neuroglucopenic hypoglycaemia might be an underestimated threat of bariatric surgery, as Roux-en-Y gastric bypass (RYBG) or gastric sleeve. We aimed to evaluate glucose variability after bariatric surgery by continuous glucose monitoring (CGM) in a real-life setting.Methods: CGM was used in twelve patients with clinical suspicion of hypoglycaemia after undergoing bariatric surgery (RYBG or sleeve), during seven days. CGM was through using i...

Craniopharyngiomas–35 years of experience in a central hospital’s Endocrinology Department

Oliveira Diana , Paiva Isabel , Guelho Daniela , Cardoso Luis , Vicente Nuno , Martins Diana , Lages Adriana , Ventura Mara , Paiva Sandra , Carrilho Francisco

Introduction: Craniopharyngiomas are rare epithelial tumors of the sellar and parasellar region, with high survival rates but with frequent tumor recurrence or persistence.Methods: Information collection from clinical records and review of the epidemiology, diagnosis, treatment and follow-up of patients with diagnosis of craniopharyngioma followed in an Endocrinology Department between 1980 and 2015. Statistical analysis using SPSS v. 22.0.<p class="...

Contribution of glucose variability to HbA1c levels in patients with type 1 diabetes

Cardoso Luis , Batista Carla , Rodrigues Dircea , Moreno Carolina , Guelho Daniela , Vicente Nuno , Balsa Margarida , Martins Diana , Oliveira Diana , Carrilho Francisco

Background: Optimal management of type 1 diabetes requires full understanding of the relationships between the triad: HbA1c, fasting plasma glucose, and glucose variability (GV). As GV may contribute to HbA1c we assessed the influence of GV in HbA1c levels.Research design and methods: We retrospectively analysed 9393 h of continuous glucose monitorings (CGMs) from 61 patients with type 1 diabetes. Periods of 24 h with missing values were excluded. We cal...

Post-operative serum cortisol levels as predictors of recurrence in Cushing's disease

Martins Diana , Guelho Daniela , Paiva Isabel , Baptista Carla , Vicente Nuno , Cardoso Luis , Oliveira Diana , Balsa Margarida , Carrilho Francisco

Introduction: Cushing’s disease (CD) is characterized by increased secretion of ACTH often as a result of a pituitary adenoma. The surgical success rates after transsphenoidal pituitary surgery (TSS) range from 53 to 96% in different centres. Postoperative cortisol levels have been proposed as the standard criteria for prediction of surgical remission however, this variable is subject of a variety of interferences.Objectives: Evaluate the potential ...
