Abstract

OBJECTIVES:To describe self-reported radiation safety practices by equine veterinary technicians in North America and identify factors associated with these practices.

SAMPLE:154 equine technicians.

PROCEDURES:An electronic questionnaire regarding radiation safety practices during the use of portable x-ray equipment was sent to 884 members of the American Association of Equine Veterinary Technicians and Assistants. Data were summarized, and various factors were evaluated for associations with reported safety practices.

RESULTS:221 of 884 (25.0%) questionnaires were completed, including 154 by equine technicians who had been involved in equine radiography as x-ray tube operators, cassette holders, or both in the previous year. Lead apron use was suboptimal, reported as "always" for 80.0% (104/130) of tube operators and 83.1% (123/148) of cassette holders. Approximately 20% of participants never wore thyroid shields, and approximately 90% never wore lead eyeglasses. Almost 50% of participants did not have lead eyeglasses available. Although > 55% of participants always held the x-ray equipment by hand, 58.4% (73/125) of tube operators and 25.0% (35/140) of cassette holders never wore gloves. Cassette holders wore lead gloves and personal radiation dose-monitoring devices significantly more frequently than did tube operators.

CONCLUSIONS AND CLINICAL RELEVANCE:Compliance of North American equine technicians with radiation safety recommendations by the National Council on Radiation Protection and Measurements was suboptimal. Improvements in radiation safety training and education, strengthening the connection between academic institutions and private practices, and greater availability and requirement of personal protective equipment use by senior clinicians and employers might aid in improving safety practices.

Case series of maggot debridement therapy demonstrates safety and efficacy for treating problematic wounds in cats and dogs in Mexico.
Treatment was administered by applying 8-10 larvae per square cm surface area directly on the wound bed and covering the wound with a sterile polyester mesh, sutured to the skin. These were left on the wound for cycles of approximately 48 hours (24-72 hours); the cycles were repeated if more than 20% necrotic tissue remained after treatment. Review of these cases revealed that 80% of treated wounds achieved 100% debridement within 48-96 hours of treatment.

If embryonic death occurs before day 35 of gestation, the embryo is absorbed. Fetal death in the second half of gestation leads to abortion or fetal emphysema, maceration, or mummification.

Association between highly pathogenic avian influenza outbreaks and weather conditions in Japan.
We found that higher average air temperatures two to three weeks prior, lower average wind speeds four weeks prior, and longer sunlight hours two and four weeks prior to outbreaks were significantly associated with increased risk of HPAI outbreaks in Japan. These results suggest that weather may influence environmental survival and transmission of the virus, as well as patterns of wild bird movement that could seed new outbreaks.
