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.

Archives Highlights:
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.
Topical and oral emodepside formulations for last-line treatment of multianthelmintic drug-resistant hookworms when given orally to dogs are not bioequivalent.
This study was conducted in 3 phases, during which dogs received single doses of emodepside as the feline topical solution (1 mg/kg) orally, the canine modified-release tablet (1 mg/kg) orally, and the topical feline solution (3 mg/kg) topically. The feline topical solution administered orally at 1 mg/kg is not bioequivalent to the canine modified-release tablet. Markedly higher absorption of the feline topical solution administered orally raises potential safety concerns for extra-label use in dogs to treat multi-anthelmintic drug-resistant hookworm infections. Poor absorption following topical administration suggests it may be unsuitable for treating multi-anthelmintic drug-resistant hookworm infections.
Retrospective cohort study on diseases and risk factors associated with death in hospitalized neonatal foals.
Most prevalent diseases were sepsis (43.9%), enteritis (14.0%), and omphalitis (9.0%). Case fatality rate was 33.3%. Neonatal sepsis significantly increased the risk of death.
Adjuvant Chemotherapy Is Associated With Prolonged Survival Time in Small-Breed Dogs Undergoing Amputation for Appendicular Osteosarcoma.
The median time to distant progression for all dogs was 265 days, with no significant difference between treatment groups. The median overall survival for all dogs was 270 days, and it was significantly different between amputated dogs (150 days) and those also receiving adjuvant chemotherapy (353 days). In our cohort, osteosarcoma in small breeds behaved as aggressive as in large breeds.
Prevalence of Encephalitozoon hellem among companion and exhibition birds in Japan.
Although microsporidia can rarely cause severe systemic infections, including hepatitis, nephritis, and enteritis in young birds, most infected birds are subclinical and thought to recover spontaneously after a period of temporary spore shedding if they do not have immunosuppression. Microsporidia can cause self-limiting infection in immunocompetent humans and life-threatening chronic diarrhea in immunocompromised individuals.
