Parathyroid tissue in ectopic thyroid tissue

Silva Joao , Ivo Catarina , Marcelino Mafalda , Passos Dolores , Simoes Helder , Lopes Luis , de Castro Joao Jacome

Introduction: Postmortem studies have shown that a fifth parathyroid gland may be present in about 5% of patients with hyperparathyroidism. 1% of parathyroid glands are located in thyroid tissue. There’s a prevalence of 7–10% of thyroid ectopic tissue.Case report: A 53-year-old male, submitted to bilateral nephrectomy due to a Grawitz tumour at the age of 25. Under haemodialysis since then (with a rejected renal transplant in the past), he was ...

Silva Joao , Ivo Catarina , Marcelino Mafalda , Lopes Luis , Passos Dolores , Simoes Helder , de Castro Joao Jacome

Introduction: Interaction between diabetes mellitus (DM) and an infection usually results in hyperglycaemia. However, there is data describing hypoglycaemia events related with the association between certain antibiotics and oral anti-diabetic drugs or insulin.Case report: Male, 73 years old, with history of hypertension, obesity and dyslipidaemia. DM type 2 was diagnosed 13 years ago with any macro or microvascular complications so far. Currently he&#14...

Lithium-associated hyperparathyroidism: a case report

Marcelino Mafalda , Silva Joao , Lopes Luis , Salgado Lucilia , Lopes Carlos , de Castro Joao Jacome

Introduction: Lithium therapy is commonly used in bipolar disorder treatment. Alongside the increasing prevalence of goiter and hypothyroidism, the sustaining use of lithium therapy is associated with several metabolic disorders, such as hypercalcemia and hyperparathyroidism (HPT).Case report: A 64-year-old woman with history of bipolar disorder treated with lithium for several years was referred to our department for evaluation of recurrent hypercalcemi...

Ferreira Florbela , Marcelino Mafalda , Wessling Ana , Nobre Ema , Leite Valeriano , Carmo Isabel

Introduction: Medullary thyroid carcinoma (MTC) is a rare form of thyroid cancer, making up about 3–5% of all cases. It is characterized by the synthesis and secretion of calcitonin (Ct). Measurement of Ct has low specificity but is a highly sensitive method for the detection of MTC. MTC with normal or only slightly elevated Ct is a rare occurrence and there are few such reports in the literature.Case report: A 61-year-old male patient was referred ...

Evaluation of thyroid surgery: 10 years of experience in a Military Hospital

Marcelino Mafalda , Lopes Carlos , Carvalho Raquel , Guerra Paulo , Passos Dolores , Vilar Helena , Lopes Luis , Castro Joao

Introduction: Thyroid surgery is nowadays associated with low morbidity and extremely low mortality. A consistent association has been observed between high surgical volume and better outcomes. Patients who undergo surgery by a skilled surgeon have fewer complications. On the other hand, different surgical techniques have been associated with different outcomes. Since 1997, thyroid diseases are treated in our department by a multidisciplinary team.Object...

Fine needle aspiration biopsy in thyroid nodular disease: 10 years of experience in a Military University Hospital

Marcelino Mafalda , Andre Saudade , Figueiredo Luisa , Passos Dolores , Vilar Helena , Lopes Luis , Carvalho Raquel , Castro Joao

Introduction: Fine needle aspiration biopsy (FNAB) plays an essential role in the evaluation of thyroid nodular disease (TND). It reduces the rate of unnecessary thyroid surgery for patients with benign nodules, and allows the choice of the appropriate surgery. In our department, 2124 FNAB were performed in 10 years. 60% of them are now ultrasound guided (UGFNAB).Objective: To access the accuracy of FNAB in our hospital.Methods: Re...

Comparison of the diagnostic criteria for PreDiabetes on a overweight population

Marcelino Mafalda , Chambel Paula , Paradinha Manuel , Domingues Andreia , Passos Dolores , Lopes Luis , Lopes Maria , Castro Joao

Introduction: ‘PreDiabetes’ was considered as a categories of increased risk for diabetes on the last ADA recommendations in 2010. The proposed diagnostic criteria include an HbA1c value between 5.7 and 6.4%, impaired fasting glucose (IFG) (100–125 mg/dl) and impaired glucose tolerance (IGT) levels (2-h values in the oral glucose tolerance test (OGTT) of 140 to 199 mg/dl). The HbA1c as new diagnostic criteria may actually increase the number of patients diagnose...

Marcelino Mafalda , Nobre Ema Lacerda , Conceicao Joao , Carvalho Arlindo , Horta Ana Paula , Jacome de Castro Joao

Background: The androgen-secreting tumors constitute fewer than 1% of ovarian tumors. Leydig cell tumor is one of the most common of this type of lesion and it is usually benign, small and unilateral.Case report: A 67-year-old women was referred to the Endocrine clinic due to hirsutism (score 22 Ferriman–Gallwey) and male type alopecia with 3 years of evolution and progressive worsening.

V. Moreira Mafalda , Pignatelli Duarte , Bernardino Raquel , Vale Fernandes Emidio , P Monteiro Mariana

Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies in women of reproductive age and, accounts for 80% of the causes of anovulatory infertility. Despite PCOS being often associated with obesity and insulin-resistance, these are not invariably present. As PCOS aetiology and underlying mechanisms remain unclear, clinical management is limited to target symptoms. Recent evidence suggested the potential of GLP-1 receptor agonists therapies in ameliorating P...
