Comparison of D-dimer concentration and thromboelastography for diagnosis of cerebrovascular accidents in dogs: A retrospective study.

Background: Cerebrovascular accidents (CVAs) in dogs are diagnosed using magnetic resonance imaging (MRI). This modality is sometimes unavailable, and CVAs can resemble other lesions on MRI. D-dimer concentration and thromboelastography (TEG) are utilized in human medicine in addition to diagnostic imaging to support diagnosis of CVAs, but their use in veterinary patients has not been assessed.

Evaluating the effectiveness of common disinfectants at preventing the propagation of Mycobacterium spp. isolated from zebrafish.

Mycobacteriosis is a bacterial disease that is common in captive, wild and research fish. There is no one causative agent of mycobacteriosis, as several strains and species of Mycobacterium have been identified in zebrafish. With increased usage and investment in wild-type and mutant zebrafish strains, considerable value is placed on preserving zebrafish health.

[Syncope and occupational risk survey: the role of continuing education and multidisciplinary approach].

Syncope is a common disorder characterized most of the times by a positive clinical outcome. However, it may turn to a life threatening event even for working colleagues and third party when occurring during an high risk job. We have recently found that, out of 670 patients admitted to the Emergency Department (ED) for syncope, about 50% were potential workers, being their age between 18 and 65 years.

[Syncope and work: role of the occupational physician and global risk stratification].

Safety risk for subjects suffering from syncope while working has not been as yet addressed by occupational medicine. The present study was aimed at evaluating a new developed methodology for job tasks risk stratification in patients with syncope. During a work-shop on syncope and occupational risk, 149 occupational physicians (OP) with about 10 years of clinical experience were asked to fulfil a Visual Analogue Scale (VAS) concerning the doctor's estimated potential damage (D) to the worker and the probability of a damage to occur (P) should syncope take place during the job task.

Studies of Venezuelan encephalitis in migrating birds in relation to possible transport of virus from South to Central America.

All of 13 species of northward migrating shorebirds and 7 species of songbirds captured on the Pacific coast of Guatemala during April and May of 1974--1976 were susceptible to infection with small doses of either an epizootic or an enzootic strain of Venezuelan encephalitis (VE) virus. They produce moderate to high levels of viremia for 2--4 days post-inoculation; levels high enough to infect both epizootic and enzootic vector mosquitoes. Viremias were often sufficient even on the 3rd day after inoculation, a time that might represent the end of a migratory flight, assuming that the physiological state of the birds after capture reflected that during migratory flight.
