View clinical trials related to Thyroid Abnormalities.
Filter by:Intensive care unit-acquired weakness (ICU-AW) is the most common neuromuscular impairment in critically ill patients. It affects more than 50 % of patients in the intensive care and is related to many problems as difficult weaning from mechanical ventilation, prolonged hospital stay and increased mortality.Thyroid disorders are also associated with neuromuscular abnormalities and may decrease the threshold for the development of any type of myopathy. However, no previous study investigated the direct relationship between thyroid dysfunction and ICUAW.This study aims at evaluation of the association between thyroid dysfunction and intensive care unit acquired weakness.
Background: - An inadequate filtering system at the Mayak nuclear weapons production facility in Ozyorsk, Russia, allowed the release of various radioactive materials, particularly I-131 (radioactive iodine) into the city's atmosphere during the 1950s. - A recent pilot study found a higher prevalence of thyroid nodules in Ozyorsk residents who were exposed to the radiation in childhood during years of heavy atmospheric emissions (1952-1953) than in children exposed in later years (between 1967 and 1991) when there were almost no radioactive releases. - Understanding the role of I-131 in the development of thyroid disease is important because I-131 is commonly used in medicine (e.g., to treat hyperthyroidism and thyroid cancer and to diagnose thyroid disease), and it is the major source of thyroid gland exposure in fallout from atomic bomb explosions, nuclear power plant accidents, and atmospheric venting from plutonium manufacturing facilities. Objectives: -To expand the pilot study to include 350 Ozyorsk residents who were exposed in childhood to moderate levels of radiation in order to evaluate thyroid disease in relation to the dose of I-131 exposure. Eligibility: -People who were born and living in Ozyorsk, Russia between 1954 and 1955, the period of mild radioactive releases from the Mayak nuclear weapons plant. Design: - Participants' thyroid gland and structure are examined with an ultrasound examination and blood tests. - Participants with a possible thyroid gland disorder are referred to specialists for additional diagnostic procedures.
