RESUMEN
It is estimated that 80% of weight lifters and body-builders take anabolic-androgenic steroids. Their long-term use is associated with a variety of pathological conditions and premature death. Anabolic-androgenic steroid abuse may lead to changes in the presentation and progression of some conditions. It remains unclear whether anabolic steroids should be given to patients with a history of abuse of these drugs who are to undergo surgery. We report on a fatal outcome following surgery in a 48-year-old weight lifter.

The phenomena of preirradiation and postirradiation fading of LiF:Mg,Ti phosphors are considered a significant practical problem in routine dosimetry because of the uncertainties introduced, especially for mixed neutron-gamma dosimetry, as different fading corrections may be necessary for the gamma and neutron contributions. We have investigated if the region of interest (ROI) method is applicable to minimizing the fading effect for thermal neutron irradiation as it is for gamma irradiation. By employing the ROI method, which consists of integration between channel 31 below the glow curve maximum and channel 16 above the glow curve maximum, a constant dose value was obtained for the period of 90 d. Thus, by employing the ROI method, a fading independent evaluation of the thermal neutron dose can be made.

A case is presented of a 54-year-old man with a not very massive pulmonary embolism. The only clinical manifestation of the disease was periodical short-lasting unconsciousness. The diagnosis was made mainly on the basis of radioisotope pulmonary examination.
