Long-term follow-up of treatment outcomes in Graves' disease and toxic nodular disease.

Purpose: Hyperthyroidism guidelines have not been updated over the past five years, despite numerous data on the subject, and recent studies providing a wide variation in treatment success rates. We aim to compare the effectiveness and safety of treatment modalities in patients with Graves' disease or toxic nodular disease.

Methods: Single center retrospective cohort study of Graves' disease and toxic nodular disease patients treated between 1983 and 2023.

2023 UPDATE: Luso-Brazilian evidence-based guideline for the management of antidiabetic therapy in type 2 diabetes.

Background: The management of antidiabetic therapy in people with type 2 diabetes (T2D) has evolved beyond glycemic control. In this context, Brazil and Portugal defined a joint panel of four leading diabetes societies to update the guideline published in 2020.

Methods: The panelists searched MEDLINE (via PubMed) for the best evidence from clinical studies on treating T2D and its cardiorenal complications.

Register-based information on thyroid diseases in Europe: lessons and results from the EUthyroid collaboration.

Objective: Registers of diagnoses and treatments exist in different forms in the European countries and are potential sources to answer important research questions. Prevalence and incidence of thyroid diseases are highly dependent on iodine intake and, thus, iodine deficiency disease prevention programs. We aimed to collect European register data on thyroid outcomes to compare the rates between countries/regions with different iodine status and prevention programs.

Standardized Map of Iodine Status in Europe.

Knowledge about the population's iodine status is important, because it allows adjustment of iodine supply and prevention of iodine deficiency. The validity and comparability of iodine-related population studies can be improved by standardization, which was one of the goals of the EUthyroid project. The aim of this study was to establish the first standardized map of iodine status in Europe by using standardized urinary iodine concentration (UIC) data.

Ensuring Effective Prevention of Iodine Deficiency Disorders.

Background: Programs initiated to prevent iodine deficiency disorders (IDD) may not remain effective due to changes in government policies, commercial factors, and human behavior that may affect the efficacy of IDD prevention programs in unpredictable directions. Monitoring and outcome studies are needed to optimize the effectiveness of IDD prevention.

Summary: Although the need for monitoring is compelling, the current reality in Europe is less than optimal.

The state of the fishery, conservation and management of the stalked barnacle Pollicipes pollicipes in Portugal.

The stalked barnacle Pollicipes pollicipes is the most important intertidal economical resource in Portugal. The assessment of the state of the fishery, conservation and management of P. pollicipes in Portugal was made for the first time in three regions with different regulations regarding this fishery: two marine protected areas ("Reserva Natural das Berlengas", RNB; and "Parque Natural do Sudoeste Alentejano e Costa Vicentina", PNSACV); and the Center coast.

Anaplastic carcinoma and toxic multinodular goiter: an unusual presentation.

A 70-year-old male was referred with hyperthyroidism and multinodular goiter (MNG). Thyroid ultrasonography showed 2 nodules, one in the isthmus and the other in the left lobe, 51 and 38 mm in diameter, respectively. Neck CT showed a large MNG, thyroid scintigraphy showed increased uptake in the nodule in the left lobe, and fine-needle aspiration biopsy showed a benign cytology of the nodule in the isthmus.

A randomized double-blind study comparing the efficacy and safety of orlistat versus placebo in obese patients with mild to moderate hypercholesterolemia.

Introduction: Obesity is a chronic disease and a serious health problem that leads to increased prevalence of diabetes, hypertension, dyslipidemia and gallbladder disease.

Objective: To evaluate the efficacy of orlistat for weight loss and improved lipid profile compared to placebo in obese patients with hypercholesterolemia, treated over a period of 6 months.

Methodology: In a 6-month, multicenter (10 centers in Portugal), double-blind, parallel, placebo-controlled study, 166 patients, aged 18-65 years, body mass index (BMI) > or = 27 kg/m2, LDL cholesterol > 155 mg/dl, were randomized to a reduced calorie diet (600 kcal/day deficit) plus orlistat three times a day or placebo.

Treatment of differentiated thyroid carcinoma: a survey.

Introduction: In January 2005, during the annual meeting of the Portuguese Society of Endocrinology, Diabetes and Metabolism, a questionnaire on the treatment and follow-up of differentiated thyroid carcinoma (DTC) was given to attendants. The aim of this study was to present the survey's results.

Methods: The questionnaire addressed the following issues: the surgical treatment of the gland and cervical lymph nodes, whole body scan and ablation with (131)I, suppression with levothyroxine, and treatment of recurrence and metastases.

PROP1 gene analysis in Portuguese patients with combined pituitary hormone deficiency.

Objective: Mutations of the PROP1 gene lead to combined pituitary hormone deficiency (CPHD), which is characterized by a deficiency of GH, TSH, LH/FSH, PRL and, less frequently, ACTH. This study was undertaken to investigate the molecular defect in a cohort of patients with CPHD.

Design, Patients And Measurements: A multicentric study involving 46 cases of CPHD (17 familial cases belonging to seven kindreds and 29 sporadic cases) selected on the basis of clinical and hormonal evidence of GH deficiency, central hypothyroidism and hypogonadotrophic hypogonadism, in the absence of an identified cause of hypopituitarism.

[Diagnosis and treatment of solitary thyroid nodule--study and evaluation in Portugal].

Introduction: The best diagnostic and treatment strategy for an approach to the nodular thyroid disease continues to be a controversial issue.

Objectives: The aim of this study was to characterise medical practice in the diagnosis and treatment of nodular thyroid disease by endocrinologists and surgeons in Portugal in 2002.

Methods: A questionnaire based on that used by the European Thyroid Association and the American Thyroid Association was drawn up.

[Treatment and follow up protocol in differentiated thyroid carcinomas of follicular origin].

Differentiated thyroid carcinoma of follicular origin (DTCFO), although not very frequent, has registered a raising incidence in the last decades. In the majority of the cases, DTCFO is a curable disease when treated and monitored by experienced, multidisciplinary teams. These factors contribute to an increasing number of DTCFO survivors requiring life-long monitoring, due to the possibility of occurrence of recurrences many years after the initial treatment.
