Introduction: Pituitary apoplexy (PA) is a rare incident defined by the occurrence of necrosis and/or haemorrhage of the pituitary gland. PA is a clinical syndrome characterized by the sudden onset of headache, vomiting, visual impairment and decreased consciousness in some cases. The objectives of our study are to describe its clinical, biological and imaging features as well as the management of PA in the region of Sfax.Patients and methods: It is a re...

The opportunity to study the effects of prolonged fasting is rare. In this study we recorded anthropometric, biochemical and endocrine changes during the refeeding period following a 44 day fast, and compared them with results from 16 age-, sex- and body mass index (BMI)-matched controls.The index subject took only water to drink during the fast. He lost 24.5kg changing his BMI from 29 to 21.6. He underwent careful slow refeeding for the first 4 days usi...

Cellular sensitivity to circulating glucocorticoids is critical and is principally determined by the level of glucocorticoid receptor (GR). GR expression is most potently regulated by glucocorticoids themselves, although the mechanism is unknown. The rat GR gene encodes at least eleven alternate and untranslated exons 1, eight of which lie in a 3kb CpG island close to exon 2. We have recently shown that individual exons 1 are subject to tissue specific expression and regulatio...

Introduction: Thyroid function is commonly impaired in β-thalassemic patients with an estimated prevalence of hypothyroidism of 9–11%. According to literature, iron overload is the main cause of tissue damage involving both thyroid and pituitary gland, thus leading to primary or secondary hypothyroidism respectively. However, thyroid morphology has been rarely investigated in adults. The aim of this study is to evaluate thyroid volume (TV) and thyroid morphology in &...

Background: Differential thyroid cancer (DTC) is classified into papillary, follicular and papillary micro thyroid cancer. Also, mean platelet volume (MPV) is an independent risk factor for cardiovascular disease. The aim of the present study was to investigate MPV values in DTC patients.Materials and methods: The levels of MPV were assessed in 183 patients with DTC 44 papillary thyroid cancer (mean age 43.±13.9) 34 papillary micro thyroid cancer (m...

Objective: There are contradictory results regarding the possible association of the TSHR polymorphism D727E with TMNG. Furthermore the influence of smoking on the thyroid volume has been reported by several authors. A possible association of smoking with thyroid nodules and particularly TMNG has not been investigated up to date.Methods: In this study, 88 patients with TMNG were included. Diagnosis was verified by ultrasonography, scinthiscan, and measur...

In the thyroid gland the volume of colloid in the follicles varies considerably. The usually used number weighted mean volume (Vn) does not describe this variation in the distribution of the volume of colloid.Aim: To develop a set of assumption-free stereological methods to determine the variation of the volume of colloid in respect of number and size and to determine the coefficient of this variation (CV). For this purpose we introduce the volume-weight...

Objective: To understand the factors associated with changes in thyroid nodule volume with previous benign citology.Material and Methods: This is a prospective single-center observational study. We included patients with a benign citology from March/2016 to May/2018 and ultrasound follow-up after 12–24 months. Initially we determined the nodule size (volume in ml), and its risk of malignancy was classified according to ATA 2015 criteria. Volume cha...

BackgroundAldosterone excess causes volume retention and cardiovascular damage. We evaluated the long-term haemodynamic changes in patients with targeted treatment of primary aldosteronism (PA) (n = 40) in comparison with essential hypertension (EH) (n = 40) and untreated normotensive controls (n = 40).MethodsPA patients were subjected to adrenal vein sampling and allocated to adren...

Introduction: Prolactin is a multifunctional pituitary hormone. The effect of prolactin on platelet activation is not well understood. Prolactinomas are the most common type of pituitary adenomas, and they are medically responsive to dopamine agonists. Mean platelet volume (MPV) is a marker of platelet function and activation. The aim of this study was to evaluate MPV values before and 6 months of cabergoline treatment when normoprolactinemia was achieved.<p class="abstext...
