Introduction: Madelung’s disease is a rare disorder characterized by a disturbance in the adipocyte metabolism. Mainly occurs in alcoholic Mediterranean male, presenting multiple, symmetrical lipomas.Case report: A 49-year-old obese man with a history of alcoholism, complaint of weight gain, soft and slow-growing swelling of the neck, and shoulders. His past history: epilepsy, alcoholic CHD, hypothyroidism, severe sleep apnea, vitiligo and HTA. His ...

Introduction: Medical therapy of acromegaly is indicated in patients who failed to achieve remission after surgery, with contraindication or refusal for surgical therapy or following radiotherapy in order to bridge the interval until complete remission.Objective: Evaluate the medical therapy – somatostatin analogs (SSA), dopamine agonist (DAs) and GH receptor-antagonist (Pegvisomant) – in acromegalic patients followed from 1988–2011.<p...

Introduction: Identification of molecular markers with a reliable prognostic value may greatly improve the management of patients with papillary thyroid carcinoma (PTC). Rac1b, a hyperactive splice variant of the small GTPase Rac1, was found to be overexpressed in colorectal, breast and lung cancer. It has been shown to sustain tumor cell survival in colorectal cancer and was reported to have a key role in the malignant progression of breast and lung tumors. The Rac1b tumorige...

Introduction: Primary hyperparathyroidism (PHPT) patients who undergo parathyroidectomy can develop isolated intact parathormone (iPTH) elevation with normal calcemia. Common causes are: renal insufficiency (RI), vitamin D deficit and hypomagnesemia.Aim: To identify clinical factors associated with iPTH elevation in patients submitted to surgery treatment.Methods: The medical records of patients admitted into Santo António&#14...

Context: Pathogenesis underlying non functioning pituitary adenoma (NFPA) formation and progression has not been well established. MEG3 is strongly expressed in the normal pituitary (NP) but not in NFPA derived from gonadotroph cells. High GSTP1 gene expression also seems to contribute to gonadotroph adenoma development. Recent reports indicate a role of miRNAs in the pituitary adenoma pathogenesis.Objective: To evaluate the expression of MEG3, DLK1, GST...

Myostatin (MSTN) is a negative regulator of skeletal muscle growth, while androgens are strong positive regulators of muscle growth and strength. Follistatin (FS) is a binding protein which inhibits MSTN action. Evidences suggest that MSTN and testosterone actions in muscle may be associated. However, the mechanisms of androgens actions are not fully elucidated. The objective of this study was to evaluate the influence of exercise training in the expression of MSTN and FS in o...

67 y/o old female, with long history of hyperthyroidism, without treatment and hypertension. Two months prior to admission, she received amiodarone 200 mg daily due to cardiac arrhythmia. One week prior to admission, she developed symptoms of Congestive Heart Failure and weight loss. Family history: hyperthyroidism in two sisters. Physical examination: acutely ill, thin female, in moderate respiratory distress. Alert, oriented x 3.BP: 155/119 mmHg HR: 150.Prominent findings: m...

Introduction: Recently, the American Diabetes Association has proposed glycated hemoglobin (HbA1c) as a diagnostic criteria for diabetes (HbA1c≥6.5%) and prediabetes (5.7%≤HbA1c≤6.4%).Aims: To compare HbA1c with fasting glucose and oral glucose tolerance test (OGTT) as diagnostic criteria for diabetes and prediabetes, in obese patients; to calculate its sensitivity and specificity when compared with standard diagnostic criteria.<p c...

Necrotizing fasciitis is a rare infection of the soft tissues with consequent necrosis of fascial planes and surrounding tissues. If misdiagnosed or not properly treated it can be fatal. It typically follows trauma and it have already been described after intramuscular or intravenous injection of insulin.The authors present a case of a 24-year-old man, with type 1 diabetes mellitus for more than ten years, admitted to the emergency room for diabetic keto...

Polycystic ovary syndrome (PCOS) is considered as a risk factor for diabetes type 2 (DM2), it is often associated with obesity, β-cell dysfunction or insulin resistance. Genetic factors underlying the association of PCOS with DM2 is unknown. Recent human genetic studies have revealed that transcription factor 7-like (TCF7L2) polymorphisms are associated with DM2 through modulation of β-cell function.The aim of this study was to test if <...
