Acute and chronic thyroid diseases are the most frequently detected disorders being second only to diabetes mellitus.The World Health Organization points out that thyroid diseases’ incidence tends to grow every year. The present paper consists of clinical practice guidelines that consider etiology, clinical course, diagnostics and treatment of acute and chronic inflammatory thyroid diseases (except those of autoimmune type).The clinical practice guidelines provide an important working tool for clinicians including specialty physicians and medical experts. Containing structured and concise information on the specific nosology, diagnostic methods and treatment tips these guidelines allow medical specialists to quickly resolve difficulties and choose the most efficient and personalized treatment (following strict principles of evidence-based medicine at the same time).The clinical practice guidelines were drawn up by highly-skilled professional team of specialty physicians approved by the Expert Council of Russian Federation’s Health Department. These guidelines contain the most complete and up-to-date information required to diagnose acute and chronic thyroiditis, provide patient care and treatment.The working group publishes the present paper in the professional journal dealing with endocrinology topics to improve healthcare quality and refine treatment of acute and chronic thyroiditis (autoimmune thyroiditis excluded). It is advisable to acquaint as many endocrinology and general (family) medicine specialists as possible with the full text of these clinical guidelines.

Primary aldosteronism (PA) is the most common form of secondary arterial hypertension. In patients with PA, more so than in the general population, there is a prevalence of insulin resistance, diabetes mellitus, metabolic syndrome, osteoporosis, and symptoms of depression; these conditions are more likely to manifest a gluco- rather than mineralocorticoid excess. This fact is of particular importance in light of recent studies that have shown that PA is often associated with glucocorticoid excess. Since the first reports of cases of combined secretion of aldosterone and cortisol in 1979, the number of cases of so-called Connshing syndrome has increased. An analysis of data from recent studies suggests that hypercortisolism in PA is closely associated with an increased risk of cardiovascular complications, metabolic disorders and post-surgical adrenal insufficiency. The most important diagnostic problem in adenomas with combined secretion is the risk of false interpretation of the results of adrenal venous sampling (AVS). The indications that suggest aldosterone-and-cortisol-co-producing adenoma are the lack of suppression of cortisol levels following a night test with 1mg of dexamethasone, and an adrenal tumo of over 2.5cm. As an alternative test capable of differentiating this type of tumor, a number of researchers have proposed measuring the level of so-called hybrid steroids in the peripheral plasma and urine. Taking into account the high prevalence and potential risks, ruling out of excess corisol secretion is obligatory in all cases of PA before AVS and when planning surgery.
Primary hyperaldosteronism (PA) - is the clinical syndrome, results from autonomous of the major regulators of secretion, aldosterone overproduction by a tumorous or hyperplastic tissue in adrenal cortex. Being the most frequent cause of secondary hypertension, PA may be represented by disorders with unilateral or bilateral aldosterone overproduction and differential diagnosis between them is crucial for choosing a right therapeutic approache: lifelong medical therapy with mineralocorticoid receptor antagonists or unilateral adrenalectomy. Adrenal venous sampling (AVS) is currently the «gold standard» test for identifying laterality of excess hormone production, unlike imaging tests, sensitivity and specificity of which is not enough, due to inability to evaluate functional activity with confidence, and also to limitations in detecting tiny abnormalities of adrenals, such as microadenoma or hyperplasia. Excluding certain cases, AVS is recommended to patients with confirmed PA, planning surgical treatment, to determine the lateralization of aldosterone hypersecretion. Described clinical case of patient with confirmed lateralization from adrenal without any detected lesions on CT-imaging and nonfunctioning tumour on contralateral side, highlights the importance of using AVS for decision to refer patients for surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
