Nonlinear Faraday rotation for optical limitation.

The possible use of the nonlinear Faraday effect for optical limitation of the laser power is investigated in a resonant Faraday medium placed between two crossed polarizers. The results are comparable with those obtained at strong magnetic fields as a result of the linear Faraday effect. Advantages of the method are the narrow bandwidth and the wide field of view. The investigations are interesting from the viewpoint of applications for optical sensor protection and automation of the experiment. All measurements are performed at the F(g) = 2 --> F(e) = 1 hyperfine structure transition of the 87Rb D1 line.

[Severe pulmonary complications of massive intoxication with calcium channel blockers and isosorbide mononitrate--a case report].

A 22-year-old man was admitted to the acute intoxication unit after suicidal intoxication with 100 tablets of verapamil, diltiazem and isosorbide mononitrate. He developed shock, paralytic ileus and adult respiratory distress syndrome (ARDS). The patient required high doses of catecholamines and mechanical ventilation with high inspiratory pressure. Pulmonary barotrauma (pneumothorax, pneumomediastinum, pneumoperitoneum and soft tissue emphysema) was a secondary complication to mechanical ventilation. It is well known that alveolar epithelial type II cells synthesize and secrete all components of the surfactant. Surfactant secretion in epithelial type II cells is inhibited by calcium channel blockers and it predisposes to develop ARDS. This case illustrates the possibility of ARDS in the verapamil and diltiazem intoxication and the need for a heightened awareness of this potential complication.
