An account is given of early discoveries concerning the nature of diseases of animals. These discoveries laid the foundations for the development of veterinary public health services in Europe. Special reference is made to developments in Germany.
The risk of ocular involvement in temporal arteritis is difficult to assess in the individual case. Using Doppler ultrasound sonography a clearly reduced flow or arrest of flow in the supratrochlear artery of the amaurotic side could be demonstrated in three patients. Attempts to compress branches of the external carotid artery caused no change of flow behaviour. Doppler sonography thus permits assessment of involvement of orbital vessels. This indicates the risk of loss of vision.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
