The applications of transcranial Doppler in ischemic stroke.

Background: This overview provides a summary of the applications of transcranial Doppler (TCD) in ischemic stroke.

Results: A fast-track neurovascular ultrasound protocol has been developed for detecting occlusion or stenosis. The technique is more reliable in the carotid area than in the posterior circulation.

[Dermatitis in cats and humans caused by Cheyletiella mites reported in Iceland.].

Cheyletiella mites (Acarina) are ectoparasites that infest cats, dogs and rabbits in many countries of the world. Upon contact with infested animals the mites may temporarily produce grouped, erythematous macules on the skin of humans which rapidly develop a central, vesicular papule. These signs are most often found on the arms and the trunk.
