Pituitary ACTH Secreting Carcinoma or metastasized Small Cell Pulmonary Carcinoma?

Lopes Sara , Margarida Monteiro Ana , Sa Juliana , Matos Catarina , Machado Catarina , Ribeiro Pedro , Almeida Rui , Marques Olinda

Pituitary carcinomas are rare and represent a challenge in clinical practice. Most secondary tumour localizations are intracranial and spinal, followed by liver, cervical lymph node, bone and, rarely, lung. PC frequently exhibit resistance to most usual therapies and the mean survival time is usually <4 years once metastases have been identified. Ectopic ACTH Syndrome is, in up to 50% cases, caused by lung tumours including carcinoids or Small Cell Lung Carcinomas (SCLC). ...

Diabetes mellitus secondary to BRCA2 gene mutation: the importance of insulin resistance and genetics in dysglycemia

Lopes Valentim , Brito Patricia , Machado Catarina , De Sousa Lages Adriana

Introduction: Diabetes mellitus (DM) results from a defect in insulin secretion and/or its action. The Breast-Cancer Susceptibility Gene 2 (BRCA2), like BRCA1, is a tumour suppressor gene, and its mutation is associated with an increased risk of breast cancer and, in males, testicular cancer. In patients with the BRCA1/2 mutation, the level of Insulin-like Growth Factor (IGF)-1 and, consequently, the peripheral sensitivity to insulin are reduced, suggesting that this ...

Roque Catarina , Fonseca Ricardo , Osorio Ana Sofia , Oliveira Sofia , Machado Catarina

We present a case of Inactivating PTH/PTHrP signalling disorder (IPPSD) revealed in aduthood in the context of respiratory alkalosis caused by covid-19 infection that led to worsening of the preexisting hypocalcemia and intensification of the usual hypocalcemic symptoms. A 39 year old female with history of subclinical hypothyroidism and bilateral cataracts was admited due to hypoxemia in the context of severe covid-19 infection with bilateral pulmonary infiltrates.

Insulinoma masquerading as neurologic disease

Machado Catarina , Tavares Patricia , Monteiro Sara , Rocha Gustavo , Oliveira Maria Joao

Introduction: Insulinomas are the most frequent cause of hypoglycemia and the most common functional endocrine pancreatic tumors. Whipple triad is often present and should alert to the diagnosis.Case report: A 36-year-old male was admitted in the emergency room with loss of consciousness, diaphoresis and blurred vision, and hypoglycemia (50 mg/dl). The patient recalled recurrent symptoms of diaphoresis, tremors and palpitations, sometimes with loss of co...

Thyroid storm subsequent to amiodarone-induced thyrotoxicosis

Machado Catarina , Tavares Patricia , Monteiro Sara , Rocha Gustavo , Oliveira Maria Joao

Introduction: Thyroid storm is a rare medical emergency with high mortality, which usually results from acute exacerbation of hyperthyroidism. Amiodarone is a highly used class III antiarrhythmic drug and amiodarone-induced thyrotoxicosis is an infrequent effect of this medication, whose treatment may be difficult.Case study: A 20-year old male with congenital cardiomyopathy (Fallot tetralogy and Ebstein anomaly), chronically medicated with amiodarone 20...

Machado Catarina , Tavares Patricia , Monteiro Sara , Rocha Gustavo , Silva Fernando , Oliveira Jose Manuel , Oliveira Maria Joao

Introduction: Radioiodine treatment (RAIT) is an effective definitive treatment for Graves’ Disease (GD) and Toxic Nodular Goiter (TNG). The aim of this study was to analyze demographic and clinical factors affecting the outcome of RAIT in patients with hyperthyroidism.Methods: Retrospective review of patients treated with RAIT for hyperthyroidism. A fixed dose of 10 mCi was administered to patients with GD and 15 mCi to patients with TNG. Treatment...

Papillary thyroid carcinoma from a thyroglossal duct cyst: a rare association

Lopes Valentim , Brito Patricia , Lages Adriana , Maciel Joana , Pereira Ricardo , Machado Catarina

Introduction: Thyroglossal duct cysts (TDC) are a very frequent congenital neck mass and are mostly benign. Papillary thyroid carcinoma (PTC) originating from a TDC represents an infrequent finding. Usually, the diagnosis is only made postoperatively after cyst’s excision.Case report: A 38-years old female patient was referred to the Endocrinology department due to Graves’ disease. She had been treated with antithyroid drugs for 18 months witho...

Education sessions in patients with adrenal insufficiency

Tavora Aldora , Lemos Ema , Duarte Isaura , Sobral Joaquim , Machado Catarina , Tavares Patricia , Rocha Gustavo , Monteiro Sara , Sousa Ana , Rodrigues Pedro , Oliveira Maria Joao

Introduction: Adrenal insufficiency (AI) is a rare and potentially life-threatening disease. The most common causes are primary adrenal insufficiency (Addison’s Disease), due to an adrenocortical disease, and secondary insufficiency, due to disorders of the pituitary gland. Chronic glucocorticoid replacement is vital and patients should be educated about how to act in acute stress situations, in order to avoid adrenal crisis. Taking this into account, we organized educati...
