[Stroke etiology and long-term need of care in ischemic stroke patients].

About 80 % of all strokes are of ischemic origin. Among these the Trial of ORG 10 172 in Acute Stroke Treatment (TOAST) classification denotes five the etiological categories: large-artery atherosclerosis, cardioembolism, small-artery occlusion, strokes of undetermined etiology and strokes of other determined etiology, which are based on imaging and diagnostic findings. The object of research is the distribution of these TOAST categories in a demographically defined population and their impact on the need of care.

Anatomic and morphometric changes to gerbil posterior cristas following transtympanic administration of gentamicin and streptomycin.

Many studies have sought to document ototoxic damage and to study repair and regeneration of mammalian vestibular sensory epithelia. However, linear density analysis of the sensory cells or use of methods that focus on detection of actin in the stereocilia and cuticular plates at the reticular lamina detect only the disappearance of "hair cells" as defined by a narrow set of criteria. The research presented here focuses on the effects of two ototoxic drugs (gentamicin and streptomycin).

Plaque, gingivitis and dental aptitude test scores of dental students.

In general, plaque and gingivitis scores were correlated negatively with the manual parameters and positively with the academic and mental parameters studied. Plaque showed significant negative correlations with the manual average and the carving test. Gingivitis also demonstrated a negative correlation, just short of significance, with the manual average, but virtually no correlation existed between gingivitis and the carving test.
