ACTH infusion at the time of unilateral adrenalectomy inhibits the early rapid compensatory growth (CAG) in the remaining adrenal. We examined the hypothesis that different duration of surgery and/or the enhanced response to the stress of surgery, induced by estradiol treatment, might modify CAG. Adult male rats untreated …

Over the last few decades, worldwide average life expectancy has grown significantly and therefore the percentage of the elderly has correspondingly increased. As a result, clinical medicine has focused much interest on the latter age group and their health problems. During the 20th century, the typical elderly patient was a person with an acute or chronic disease but typically without any major disability…

A 6-year old girl was examined having two years previously presented a transient Cushing’s syndrome, followed by recurrent hyponatremia, attributed to inappropriate ADH secretion (SIADH). The brain MRI showed no abnormalities on repeated examinations, except for a suggestion of empty sella syndrome. During the past two years she also presented recurrent episodes of a prolonged febrile illness of unknown origin…

Atrial Natriuretic Peptide (ANP) is a hormone produced by cardiac atrial myocytes. Thyroid hormones may affect its release. The aim of this study was to analyze the effect of hyper and hypothyroidism on the secretion of ANP and its relationship with the changes of the renin-angiotensin-aldosterone system. Plasma ANP concentration as well as plasma renin activity (PRA) and aldosterone …

Radioactive iodine is a widely used treatment for hyperthyroidism caused by solitary autonomously functioning thyroid nodule (toxic adenoma). The aim of this retrospective analysis is to report the long term effects of this therapy on the thyroid function of patients with toxic adenoma treated in our department. Between 1968 and 1996…

Both smoking and thyroid dysfunction are frequent in the general population. Many studies have shown that cigarette smoking interferes with thyroid function and with the evolution of thyroid pathology (e.g. goiter formation and thyroid cancer development). Some studies have also suggested a significant correlation of Graves’ hyperthyroidism and Graves’ ophthalmopathy…

Severe Graves’ ophthalmopathy constitutes a complex therapeutic challenge and treatment outcome often is not satisfactory. Established methods of treatment include high-dose glucocorticoids, orbital radiotherapy and orbital decompression. Recently, the use of intravenous glucocorticoids has been shown to provide more favorable results than oral glucocorticoids…

Nuclear receptors are ligand-regulated transcription factors that evolved from an ancestral orphan receptor into a highly diverse family present throughout the entire animal kingdom. They encompass receptors for steroid and non-steroid hormones, vitamins and metabolic intermediates. These receptors signal through endocrine, paracrine, autocrine and intracrine networks …

Many Greek and Latin medical terms are in use on account of the fact that modern day Western conventional medicine originates in Greek and Roman anti-quity. The writings of Hippocrates and Galen, as well as of Celsus and Plinius…

The purpose of this study was to investigate the value of “high-resolution ultrasonography” in the differential diagnosis of benign from malignant thyroid nodules. The study included ultrasonography examination of 77 patients with thyroid nodules, who underwent thyroidectomy. The histological findings were subsequently compared …
