With a binary response Y, the dose-response model under consideration is logistic in flavor with pr(Y=1 | D) = R (1+R)(-1), R = λ(0) + EAR D, where λ(0) is the baseline incidence rate and EAR is the excess absolute risk per gray. The calculated thyroid dose of a person i is expressed as Dimes=fiQi(mes)/Mi(mes). Here, Qi(mes) is the measured content of radioiodine in the thyroid gland of person ...

BACKGROUND Use of recombinant human thyrotropin increases the thyroid radioiodine (iodine 131 [(131)I]) uptake and may have a role in the context of (131)I therapy of benign goiter. METHODS In a double-blind, placebo-controlled trial, 57 patients with nodular nontoxic goiter (51 women and 6 men) were randomized to receive either 0.3 mg of recombinant human thyrotropin (n = 28) or placebo (n =...

This is the case report of a 39-year-old lady who presented with clinical and laboratory features secondary hypothyroidism two years after achieving biochemical resolution Graves' disease cessation anti-thyroid medications. The thyroid function tests at presentation revealed: Serum T3 1.33ng/ml (normal range 0.8-1.7ng/ml), T4 2.92 4.5-12.0µg/dl), TSH 0.2mIU/l 0.5-5.0mIU/l). Thyroid-related auto...

The functions of hypothalamic-pituitary-thyroid axis are attenuated in type 1 diabetes mellitus due to insulin deficiency. The use of intranasally administered insulin is of considerable interest for treatment of diabetes and cognitive disorders, but its effect on the thyroid system has not been investigated yet. We studied the influence of long-term treatment with intranasal insulin on the hyp...

orthopantomography is a well-established imaging technique in dental diagnosis. although its exposure to individuals is relatively low compared to other diagnostic radiology examinations, it is still the most frequent x-ray examination. so it is important to estimate absorbed dose to critical organs in this examination. the present study was designed to determine the radiation doses to eyes, pa...

OBJECTIVE To quantify the radiation dose in the thyroid attributable to different CT scans and to estimate the thyroid cancer risk in pediatric patients. METHODS The information about pediatric patients who underwent CT scans was abstracted from the radiology information system in one general hospital between 1 January 2012 and 31 December 2012. The radiation doses were calculated using the I...

Radiation exposure dosimetry for the personnel is based on measurements of phantom studies. To determine effective dose values for different X-ray equipment, TLD-measurements were performed using an Alderson Phantom in the patient position and a second phantom in the typical position of the personnel. Various types of protective clothing as well as fixed shields were considered in the calculati...

OBJECTIVE The aim is to study the incidence of thyroid cancer in surgically treated nodular thyroid disease, clinicopathological characteristics and treatment results. METHODS A retrospective review of 45 patients with thyroid malignancy at King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia during a 3-years period between January 2000 through to December 2003 was carried out...
