Interventions and controls to prevent emergency service vehicle incidents: A mixed methods review.

Background: Emergency service vehicle incidents (ESVI), including crashes, rollovers, and roadside struck-by-incidents, are a leading cause of occupational fatality and injury among firefighters and other emergency responders. Though there are numerous strategies and interventions to prevent ESVIs, the evidence base for these strategies is limited and dispersed. The goal of this study was to gather and present a review of evidence-based ESVI interventions.

Identification of profilin as an IgE-binding component in latex from Hevea brasiliensis: clinical implications.

Considering the high occurrence of profilin as an allergen in many plant species, the assumption was made that profilin might be an allergen in Hevea brasiliensis, a member of the latex producing Euphorbiaceae family. Using IgE-binding inhibition by purified profilins we demonstrated that profilin is an IgE-binding component in the cytosolic fraction of natural latex and, to a lower extent, in the rubber fraction. Thirty-five out of 36 sera containing IgE to ragweed-profilin reacted with profilin from latex, indicating structural homologies between profilins from latex and ragweed.

[Challenge provocation tests and nonspecific bronchial hyperreactivity in occupational asthma].

The aim of the study is to determine the interest of realistic challenge (nasal and bronchial) in occupational respiratory symptoms appearing during work. 75 patients were included in the study. The protocol included prick tests, measuring total and specific IgE, spirometry and metacholine test to assess bronchial hyperreactivity (BHR), realistic challenge by rhinomanometry and plethysmography measuring NR (nasal resistance) and RWA (Airway resistance).

[Occupational asthma and rhinitis: challenge tests and nasal hyperreactivity: current practice and future perspectives].

Nasal hypersensitivity is defined by an exaggerated response to certain specific stimuli such as a work-related agent, non-specific stimuli (irritant effect), or to allergic or inflammation mediators. The study of nasal hypersensitivity always involves provocation tests with other practical assays. In the occupational context, the provocation test most routinely used are "challenge tests", carried out with suspected substances provided by the patient, and non-specific tests with mediators (histamine and carbachol).
