DIAGNOSTIC AND CLINICAL ASPECTS OF NORMOCALCEMIC PARATHYROID HYPERPLASIA AND NON-RENAL SECONDARY HYPERPARATHYROIDISM IN EXPOSED AND NON;EXPOSED TO IONIZING RADIATION INDIVIDUALS (LITERATURE REVIEW AND OWN RESEARCH DATA).

Parathyroids are the key regulators of calcium-phosphorus metabolism. By means of parathyroid hormone they respond to any changes in the serum level of calcium and phosphorus ions and determine the integrity of skeleton, affecting almost all systems and cells where calcium and phosphorus are involved in metabolism and/or signaling.Disorders of parathyroid function are associated with significant complications accompanying secondary hyperparathyroidism.

CHARACTERISTICS OF NON-RENAL NORMOCALCIEMIC HYPERPARATHYROIDISM IN THE CHORNOBYL NPP ACCIDENT SURVIVORS.

Objective: to assess the hormonal and metabolic disorders in the Chernobyl nuclear power plant (ChNPP) accident survivors (AS), having got secondary normocalcemic non-renal hyperparathyroidism (HPT) in the late period upon exposure to ionizing radiation (IR).

Materials And Methods: The routine clinical, anthropometric, instrumental (thyroid and parathyroid diagnosticultrasound), laboratory (biochemical, hormonal), statistical methods were applied. In both prospective (n = 48, control group n = 19) and retrospective studies the data of 2,234 subjects including 1,372 irradiated adults (862 non-irradiated persons in the control group) were evaluated.

PROBLEMATIC ASPECTS, COMPLICATIONS, MISCONCEPTIONS AND DEBATABLE ISSUES OF IODINE PROPHYLAXIS IN RADIATION EVENTS (REVIEW).

Unlabelled: Prerequisite. Since the advent of nuclear energy, industry and weapons, a possibility of radiation events i.e.

CLINICAL-METABOLIC AND HORMONAL RELATIONSHIPS BETWEEN PARATHYROID DISEASE AND OTHER NON-CANCEROUS ENDOCRINE DISORDERS IN THE CHORNOBYL NPP ACCIDENT SURVIVORS.

Objective: to investigate the clinical, hormonal-metabolic and structural features of parathyroid injuries in sur-vivors exposed to ionizing radiation after the Chornobyl NPP accident in adulthood and childhood, both with theirconnections to other non-cancerous endocrine disorders, and to establish the respective interhormonal and dys-metabolic relationships.

Materials And Methods: Clinical effects of ionizing radiation on the endocrine system in persons affected by theChornobyl NPP accident (n = 224) and their descendants (n = 146), compared with the general population sample(n = 70) were the study object. All patients underwent the ultrasound thyroid and parathyroid examination.

[HYPERPARATHYROIDISM AND PARATHYROID LESIONS IN THE ChNPP ACCIDENT SURVIVORS].

Objective: Study of the status of parathyroid glands in individuals exposed to ionizing radiation as a result of the ChNPP accident and comparison with the general population of Ukraine.

Materials And Methods: Subjects exposed as a result of the ChNPP accident (n = 1,348) and people from the general population of Ukraine (n=655) were examined. Diagnostic ultrasound scan of thyroid and parathyroid glands (PTG) was conducted in all study subjects.
