Author Abstract

Background: Use of lasers in veterinary medicine has significantly increased over the past decade. What was once a piece of equipment, almost exclusively used by veterinary specialists, has now become a common piece of equipment in general veterinary practices. It is imperative to know the appropriate situations and diseases for which lasers can be used.

Aim of the article: This article covers the basics of lasers, including discussion of both diode and CO₂ lasers. It also discusses several skin diseases and/or conditions in which lasers are commonly used.

Aseptic protocol breaches are common among veterinary students scrubbing, gowning, and gloving into surgery.
At least 1 aseptic protocol breach (APB) was noted in 46.3% of the 96 procedures observed. The most common mistakes noted were contact of the sterile towel onto nonsterile surfaces (17.7%), contact of the gown with nonsterile surfaces (17.7%), touching sterile objects with bare hands (12.5%), and improper scrubbing technique (17.4%).

Prevalence of discospondylitis and association with congenital vertebral body malformations in English and French bulldogs.
The prevalence of discospondylitis was 3.4 (1.6-6.7) times higher in French bulldogs and 4.3 (1.7-9.8) times higher in English bulldogs, compared with the overall hospital cohort. One or more vertebral malformations were present in 12 French bulldogs (92.3%), 6 English bulldogs (75.0%), and 1 "other" breed dog (1.1%). Discospondylitis was diagnosed adjacent to congenital vertebral body malformations in 12 (80%) intervertebral discs in French bulldogs and 5 (50%) intervertebral discs in English bulldogs.

Trust in veterinarians and association with vaccine information sources and vaccination status among dog and cat owners.
62.9% of dog and 61.2% of cat owners were classified as trusting their veterinarians. On average, dog owners consulted 2.50 sources about vaccine information; cat owners consulted 2.27 sources. Veterinarians were the most common primary sources of information for 85.4% of dog owners with high levels of trust, but only 62.6% of dog owners with lower levels. This was the case for 83.8% and 56.3% of cat owners.

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.

Recovery of ambulation in small, nonbrachycephalic dogs after conservative management of acute thoracolumbar disk extrusion.
Forty-nine of fifty-one (96%) of deep pain-positive and 10/21 (48%) of deep pain-negative dogs recovered ambulation within the 12-week period. The median time to ambulation was 11 and 25 days for deep pain-positive and -negative dogs, respectively. Reduction in spinal cord compression varied among individuals from minimal to complete and apparently was unrelated to the recovery of ambulation.
