Introduction: During pregnancy, the thyroid volume (TV) increases by 20% to 35% in areas with iodine deficiency. In iodine-sufficient countries, while some studies showed an increase in TV by 10–15%, others did not observe any change in TV during pregnancy. Thyroid nodules may be present in up to 15–35% of pregnant women in areas with moderate iodine deficiency. However, in areas with iodine-sufficient, thyroid nodules were investigated in a few number of studies...

Introduction: The changes observed in thyroid ultrasound during pregnancy are related to the nutritional status of iodine, but its association with TSH levels or the presence of thyroid peroxidase antibodies (TPOAb) is unclear.Objective: To compare the relationship between the findings in thyroid ultrasound and thyroid function tests in the first trimester of pregnancy in an iodine sufficient area.Subjects and methods: We conducted...

Objective: To compare the results of immunohistochemistry (IHC) and DNA sequencing in detection of BRAF V600E mutation in papillary thyroid carcinomas (PTC). BRAF V600E mutation is the most common genetic alteration in papillary thyroid carcinomas and is associated with worse prognosis. Direct sequencing is usually performed, but less expensive immunohistochemistry can be used instead.Methods: Study was performed in 54 consecutive PTCs during 2014–2...

Fibroblast growth factor 21 (FGF21) is an emerging regulator of energy homeostasis and a novel target for the development of therapies to treat diabetes, cardiovascular disease, and obesity. FGF21 was discovered in an in vitro high throughput screen. It was later shown to have impressive metabolic pharmacology including glucose, lipid, and body weight lowering effects in a variety of animal models, including non-human primates. When tested clinically an FGF21-based an...

Objective: Cushing’s disease (CD) is caused by pituitary corticotrophin (ACTH)-secreting tumours. Our aim is to show our experience in a third level hospital attending a 500 000 based population area from 1990 to now.Methods: We review retrospectively the medical reports of all patients diagnosed as CD from 1990 by a data collection protocol. We reject the reports without enough or inadequate information. We present results by using descriptive stat...

Introduction: Retrospective study of patients undergoing thyroid surgery at the Hospital Virgen de la Luz, Cuenca (Spain) during the years 2010–2013.Material and methods: We evaluated data of 92 patients basically with nodular thyroid disease, who were studied and treated in our hospital.Results: Our series is made up of 92 patients (25% men and 75% women) with an average age of 52 years. The most common form of presentation (...

Objective: We investigated the clinical usefulness of thyroid blood flow measurement by colour-flow Doppler ultrasonography in predicting relapse of Graves’ disease (GD).Patients and methods: In 30 euthyroid GD patients, (eight males and 23 females), aged 17–68 years (mean 43.8±12.8), after at least 1 year of treatment with anti-thyroid drug (ATD) and just before its withdrawal, we evaluate with colour-flow Doppler ultrasonography the colo...

Introduction: 25-Hydroxyvitamin D (25(OH)D) deficiency is a growing healthcare problem in HIV-infected patients. Evidence suggests that an optimal level of 25(OH)D would avoid secondary hyperparathyroidism but its optimal serum concentration has not been defined in HIV-infection. The aim of our study was to identify the 25(OH)D serum concentration that correlates to i-PTH increase and describe the prevalence of hypovitaminosis D in a cohort of HIV-infected patients.<p clas...

TSH level has been proposed as a thyroid malignancy predictor in nodular thyroid disease. In addition, several clinical studies have reported that higher preoperative serum TSH levels were associated with more advanced stages of differentiated thyroid cancer (DTC) at the time of diagnosis.Methods: We collected retrospectively preoperative serum TSH from patients diagnosed of papillary thyroid cancer (PTC) who had undergone total thyroidectomy during the ...

The performance of late-night salivary cortisol (LNSC) and optimal number of samples to accurately diagnose post-operative recurrence of Cushing’s disease (CD) at an early-stage are unknown. We performed a retrospective analysis in a single tertiary-care center to compare the accuracy of multiple salivary sampling strategies to diagnose early-stage recurrences of CD. 36 patients in remission of CD after surgery were followed up for 69.2±10.6 mo with multiple successi...
