Background and aim: The normal range of thyroid functions during pregnancy differs between ethnic groups. The aim of this work was to assess the thyroid functions in normal pregnant Egyptian females in order to establish a population-specific reference range. Thyroid peroxidase antibodies (TPO Abs) and thyroid volume were also assessed.Methods: The study included 150 normal pregnant Egyptian females (with no history suggestive of thyroid...

Autoimmune Thyroid Disease (ATD) is associated with normal thyroid function (type 1) in most cases with variable incidence of functional evolution toward either hypo (type2, A or B if present or not goiter) or hyperthyroidism (type3).To study the evolution of thyroid function in a longitudinal study, along a scale of six years, in relationship to thyroid volume, 128 subjects (80 females and 48 males), aged from 28 to 78 years, were considered, with the f...

Hyperprolactinaemia in the presence of pituitary tumour can occur from tumour secretion or from stalk compression causing loss of dopaminergic inhibition. It is generally accepted that, in the presence of a large pituitary mass, a serum prolactin level up to 3000mU/l indicates stalk compression rather than a prolactinoma; the clinical diagnosis of prolactinoma depends on the degree of hyperprolactinaemia in the context of pituitary tumour size. Our aim was to examine more form...

Introduction: Previous reports have shown that subjects with insulin resistance have increased thyroid volume and nodule prevalence. We investigated the effects of metformin on thyroid volume and nodule size.Methods: This prospective data were gathered on newly diagnosed subjects with insulin resistance (n=100, 68 female, 32 male) between August 2008 and May 2010. Measurements of thyroid hormones and thyroid ultrasonography was performed in all ...

Objective: To find a relation between thyroid parameters (thyroxin serum level, thyroid antibodies, thyroid gland volume and ultrasound texture) and serum level of selenium.Background: Selenium deficiency can lead to a decrease of triiode-thyronine in peripheral tissues. Changes in thyroid hormone production can be reflected in followed thyroid parameters.Methods: In 33 patients ultrasound examination of thyroid gland was performed...

Background: Body Mass Index (BMI) and waist circumference (WC) are currently used to assess obesity. BMI and WC do not take into account fat/muscle distribution or allow for distinctions between gender, age or ethnicity. WC reflects abdominal fat distribution more accurately, but is operator-dependant and variable in terms of reproducibility. BVI is a totally new, reproducible and novel concept using a 3D body scanner and appropriate software, to measure total body and 8 body ...

Introduction: Bariatric surgery would end up with great alterations in homeostatic measures such as glucose and lipid metabolism and hormonal regulation, which of all are interweaved with some number of ways to each other. The hormonal modulation extands along a wide span starting from the change in gastrointestinal peptides, to the effect in insulin and other nutrient metabolism regulatory hormones and even the hormones establishing thyroid and calcium homeostasis. Secondary ...

Aim: Overt/subclinic hypothyroidism and hyperthyroidism are known to be associated with cardiovascular risks. There have been no studies evaluating the relationship between nodule presence and arterial stiffness in individuals with euthyroid nodular goitre. Our aim in this study is to demonstrate whether nodule presence and nodule stiffness affect arterial stiffness in individuals with euthyroid nodular goitre by using pulse wave analysis (PWA).Materials...

Background: Measuring testicular volume (TV) by orchidometer is a standard method of pubertal staging in boys. A paucity of evidence exists as to its inter and intra-user reliability and the impact of clinicians’ gender, training and experience on the accuracy of measurements. Specifically engineered prosthetic models of different size testes were developed to investigate the reliability of TV estimation.Method: The study was conducted over the thre...

We evaluated the volume of pituitary adenoma in patients treated with ocreotide LAR (SSLAR) prior to surgery.Materials and methods: Twenty-six patients (22 females and 4 males, mean age 57.5±15.0 years) were treated with SSLAR: 5 patients with microadenoma – during 6 months, and 21 patients with macroadenoma – during 12 months before surgery, as recommended by the Polish Society of Endocrinology. Concentration of hGH and IGF1 was evaluated...
