Von Hippel-Lindau disease: a case report

Gouveia Sofia , Ribeiro Cristina , Paiva Sandra , Joao Bugalho Maria , Santos Jacinta , Vieira Alexandra , Alves Marcia , Carvalheiro Manuela

Introduction: Von Hippel-Lindau disease (VHLD) is a rare autosomal-dominant syndrome, characterized by the development of multiple cysts and tumours, namely retinal and central nervous system hemangioblastomas, renal cell carcinoma (RCC), phaeochromocytoma, pancreatic endocrine tumours (PET) and endolymphatic sac tumours.Most germinal mutations are missense, related to a high risk for presenting phaechromocytoma (specially if Arg167Trp mutation im...

Ultrasound fine needle aspiration (US – FNA) in an Endocrinology Department: our reality and results quality

Ribeiro Cristina , Paiva Sandra , Gouveia Sofia , Fernandes Graca , Melo Miguel , Santos Jacinta , Vieira Alexandra , Alves Marcia , Carrilho Francisco , Carvalheiro Manuela

Introduction: High-resolution US and US FNA are techniques of great relevance in the evaluation of thyroid nodules. They are being used much more often by endocrinologists all over the world. In our Endocrinology Department, we started them in 2006; since then they have been progressively amplified. We present our results of US FNA performed from January 2007 until December 2009.Patients and methods: Two thousand eight hundred and seventy-seven FNA were ...

Diabetic ketoacidosis and dapagliflozin: a case report

Catarino Diana , Ribeiro Cristina , Oliveira Diana , Martins Diana , Lages Adriana , Ventura Mara , Cunha Nelson , Fadiga Lucia , Marques Bernardo , Carrilho Francisco

Introduction: Dapagliflozin is an oral antidiabetic drug, recently approved for type 2 diabetes and is a sodium-glucose cotransporter type 2 inhibitor (iSGLT2). Its mechanism of action is glycosuria induction, associated with lowering glycemia. The effects of SGLT2 inhibition are insulin-independent, and efficacy is not affected by declining β-cell function or insulin resistance. Additional benefits: weight loss, reduction in blood pressure, lower inciden...

Clinical and histopathological factors associated with the prognosis of medullary thyroid cancer in a tertiary center

Martins Ferreira Mafalda , Carvalho Tania , Madeira Joana , Lopes Sofia , Melo Miguel , Ribeiro Cristina , Saraiva Joana , Oliveira Patricia , Paiva Isabel

Introduction: Medullary thyroid cancer (MTC) is a rare tumour. Mostly sporadic, 25% are associated with multiple endocrine neoplasia (MEN2A/B) or isolated familial MTC. Surgery is the only curative option: its response is defined as complete (no evidence of biochemical or structural disease), incomplete (only structural response) and persistence of structural disease. We aimed to analyse the clinical and pathological factors associated with the prognosis of MTC.<p class="a...

Medullary thyroid carcinoma – a 22-year case series from a tertiary hospital center

Carvalho Tania , Martins Ferreira Mafalda , Madeira Joana , Lopes Sofia , Saraiva Joana , Oliveira Patricia , Melo Miguel , Ribeiro Cristina , Paiva Isabel

Introduction: Medullary thyroid carcinoma (MTC) arises from thyroid parafollicular C cells and accounts for <5% of thyroid cancers. Nearly 25% occur in the context of multiple endocrine neoplasia type 2 syndrome (MEN2) or familial isolated MTC.Objectives: Evaluation of clinical characteristics and evolution of patients with MTC.Methods: Retrospective analysis of clinical records of patients with MTC diagnosed from 2001 to 2023....

Idiopathic versus autoimmune type 1 diabetes – long-term differences

Catarino Diana , Silva Diana , Pereira Claudia , Ribeiro Cristina , Ruas Luisa , Cunha Nelson , Fadiga Lucia , Guiomar Joana , Lavrador Mariana , Vieira Ines , Cardoso Luis , Paiva Isabel , Bastos Margarida

Introduction: The American Diabetes Association proposed two subcategories for type 1 diabetes: autoimmune type 1 diabetes (ADM) and idiopathic type 1 diabetes (IDM). The absence of β-cell autoimmune markers and lack of association with HLA haplotypes define the second category, whose pathogenesis remains unclear. Only a minority of patients with type 1 diabetes fall into this subcategory which is considered by several authors similar to type 2 diabetes.<p class="abst...

Autoimmune diabetes mellitus versus idiopathic: differences at diagnosis

Silva Diana , Catarino Diana , Pereira Claudia , Ruas Luisa , Ribeiro Cristina , Cunha Nelson , Fadiga Lucia , Guiomar Joana , Cardoso Luis , Paiva Isabel , Carrilho Francisco

Introduction: The American Diabetes Association proposed two categories for the classification of type 1 diabetes mellitus (DM): autoimmune (AI) and idiopathic (ID). The absence of autoimmune markers or association with HLA haplotypes defines the second category. Only a small minority of patients with type 1 diabetes fall into this category.Objective: To evaluate the clinical characteristics of both categories and to analyze the differe...

Corticotroph adenoma associated with a rare infection – case report

Catarino Diana , Ribeiro Cristina , Cunha Nelson , Fadia Lucia , Silva Diana , Guiomar Joana , Lavrador Mariana , Vieira Ines , Saraiva Joana , Rodrigues Dircea , Paiva Isabel , Gomes Leonor , Bastos Margarida

Introduction: Cushing Syndrome have long been recognised to predispose patients to infection diseases, a consequence of the immunosuppression induced by corticosteroids. There is a predisposition to viral, bacterial, parasitic and especially fungal diseases. Opportunistic infections, particularly invasive fungal infections, represent a serious complication associated with an increased risk of mortality.Clinical case: We represent a 55 years-old woman, po...

Low/undetectable pre-ablation thyroglobulin in well-differentiated thyroid cancer patients with positive post-ablative 131I whole body scans: causes and consequences

Guelho Daniela , Alban Fernando , Melo Miguel , Ribeiro Cristina , Paiva Isabel , Moreno Carolina , Vicente Nuno , Cardoso Luis , Martins Diana , Oliveira Diana , Balsa Margarida , Costa Gracinda , Carrilho Francisco

Introduction: In patients with well-differentiated thyroid cancer (DTC) low/undetectable thyroglobulin (Tg) at time of remnant ablation usually reflects a complete previous surgery. However, in a small percentage (6.3–16%) it can represent false negative values.Objectives: Evaluate the frequency of patients with low/undectable Tg at time of remnant ablation with locoregional or distant lesions at post-ablative 131I whole body scan (WBS) a...

Lymphocytic thyroiditis and differentiated thyroid cancer – challenges in follow-up

Oliveira Diana , Ribeiro Cristina , Martins Maria Joao , Paiva Sandra , Melo Miguel , Moreno Carolina , Guelho Daniela , Vicente Nuno , Cardoso Luis , Martins Diana , Carrilho Francisco

Introduction: Chronic lymphocytic thyroiditis (LT) is a very common condition, and its coexistence with papillary thyroid carcinoma has often been reported. Analytical and echographic challenges must be kept in mind in the follow-up of patients with both these disorders.Case report:: We present the case of a woman with a history of multinodular goitre who underwent left thyroidectomy and isthmectomy at the age of 43, with the histopathological finding of...
