Introduction: Parathyroidectomy is the only curative treatment for primary hyperparathyroidism (pHPT) and has been traditionally performed through bilateral neck exploration (BNE). However, with the use of intraoperative parathyroid hormone (IOPTH) assay along with preoperative localization exams, minimally invasive surgery can be performed with good surgical success rate.Aim: To evaluate the usefulness of IOPTH assay in guiding adequate parathyroidectom...

Introduction: Hypoparathyroidism (hypoPTH) is one of the most feared iatrogenic complications of the surgical treatment for thyroid cancer (TC). Despite supplementation with calcium salts and calcitriol, hypoPTH seems to be associated with a negative impact on quality of life (QoL), which has not been evaluated in the Portuguese patients.Objectives: To evaluate the impact of hypoPTH on the QoL of Portuguese patients with TC and its correlation with serum...

Introduction: Adrenocortical carcinoma (ACC) is a rare endocrine malignancy with poor prognosis. Objective: The aim of this study is to characterize patients with ACC followed at a tertiary center. Material and Methods: Retrospective analysis of clinical records of patients with histopathological diagnosis of ACC followed in our clinic. Results and conclusions: We reviewed 11 patients. The average age at diagnosis was 57.3±15.2 years and 63.6% were females. Seven patients...

Introduction: Primary hyperparathyroidism (pHPT) is the most common cause of hypercalcemia in the outpatient setting and is a frequent endocrine disorder. Large cohort studies of pHPT patients in the Portuguese population are scarce. Aim: To characterize patients with pHPT followed at a tertiary center.Material and Methods: Retrospective analysis of clinical records of patients with pHPT followed in our hospital from 2003 to 2021. ...

Introduction: Multiple endocrine neoplasia type 1 syndrome (MEN1) is a hereditary autosomal dominant disorder caused by germline mutations in the MEN1 tumour-suppressor gene and is typically characterized by parathyroid adenomas, duodenopancreatic neuroendocrine tumors (NETs) and pituitary adenomas. Breast cancer has recently been identified as manifestation of MEN1 and female patients have early onset elevated breast cancer risk.Case report: Female pati...

Background: Assessment of response to therapy is a valid tool for dynamic risk stratification in patients with differentiated thyroid cancer (DTC). It is well documented in patients treated with total thyroidectomy and radioiodine ablation therapy (RAI), but data is still sparse regarding patients treated with lobectomy. Our study aimed to evaluate response to therapy in patients with DTC treated with lobectomy.Methods: We performed a retrospective study...

Introduction: Struma ovarii is a rare form of ovarian teratoma mostly composed of thyroid tissue. In about 5% of the cases, well-differentiated thyroid carcinoma may arise in struma ovarii. As this medical entity is so exceptional, there is still no consensus on diagnosis and treatment.Case Reports: A 52-year-old old woman was submitted in 2009 to total hysterectomy with bilateral adnexectomy and pelvic lymphadenectomy. Histopathology r...

Introduction: Primary hyperparathyroidism (PHPT) is a common endocrine disorder characterized by hypercalcemia due to an unregulated overproduction of parathyroid hormone (PTH). PHPT is most commonly caused by a single adenoma of the parathyroid gland, usually located just behind the thyroid gland. However, in rare cases, they can have an ectopic location, including intrathyroid adenomas. In some cases, the measurement of intact PTH in the wash out fluid obtained by US-Fine Ne...

IntroductionParagangliomas (PGL) of the urinary bladder are an extremely rare entity. During pregnancy, PGL can carry higher risk of foetal and maternal mortality, which can be significantly reduced when the diagnosis is made antepartum and adequate multidisciplinary management and surveillance is started. However, despite clinical stability, delivery complications rates are still higher than in the general obstetric population.Cas...

IntroductionIn march 2020, the COVID-19 pandemic registered its first cases in Portugal, leading the government to impose lockdown, in order to prevent the spread of cases. With social isolation and outpatient activity being ceased, there was an increase in mortality of non-COVID patients. The lockdown recommendations are in contradiction with comprehensive diabetes care and reflected in less regular patient-provider interactions, which in some cases con...
