Prevalence of Thyroid Nodules in Residents of Ukraine Exposed as Children or Adolescents to Iodine-131 from the Chornobyl Accident.

Although childhood exposure to radioactive iodine-131 (I-131) is an established risk factor for thyroid cancer, evidence for an association with thyroid nodules is less clear. The objective of this study is to evaluate the association between childhood I-131 exposure and prevalence of ultrasound-detected thyroid nodules overall and by nodule histology/cytology (neoplastic/suspicious/non-neoplastic), size (<10 mm/≥10 mm), and number (single/multiple). This is a cross-sectional study of radiation dose (mean = 0.

Neonatal outcomes following exposure in utero to fallout from Chernobyl.

Iodine 131 (I-131), the principal component of nuclear fallout from the Chernobyl accident, concentrates in the thyroid gland and may pose risks to fetal development. To evaluate this, neonatal outcomes following the accident in April of 1986 were investigated in a cohort of 2582 in utero-exposed individuals from northern Ukraine for whom estimates of fetal thyroid I-131 dose were available. We carried out a retrospective review of cohort members' prenatal, delivery and newborn records.

Xenotransplantation of cultured newborn pig thyroid tissue for the treatment of post-radioiodine hypothyroidism in rats.

The aim of the present study was to develop atransplantation technique for restoration of thyroidfunction in rats with radioiodine-inducedhypothyroidism. Each Wistar rat received the dose of75.0 muCi of 131-iodine by intraperitonealinjection.

[Permanent hypoparathyroidism due to thyroid cancer surgical procedures in patients exposed to radiation in the Chernobyl, Ukraine, nuclear reactor accident].

Background And Objective: Postoperative hypoparathyroidism is a rare, but complex endocrine disorder. The purpose of this case series study was to evaluate the symptoms, signs and sequelae of the disease in a major homogeneous patient group after the Chernobyl accident in the Ukraine.

Patients And Methods: This study is based on a random sample of 25 patients with symptomatic permanent hypoparathyroidism after surgical procedures on the thyroid for carcinoma following the Chernobyl accident in May 1986.
