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:
Case Series: Computed Tomography Features of Extraskeletal Osteosarcoma in Six Dogs.
Although the presence of intralesional mineralization is not a pathognomonic finding, it was consistently identified in the present case series. Therefore, exOSA should be considered in the differential diagnosis when mineralization occurs in a mass unrelated to osseous structures.
Owner survey suggests cats may be undertreated for pain compared to dogs after an elective ovariohysterectomy or orchiectomy.
Analgesics were prescribed for 19 of 162 (12%) pets: 14 of 88 (16%) dogs and 5 of 74 (6.7%) cats. There was no difference in the prescription of analgesics between dogs and cats after ovariohysterectomy or orchiectomy. 15 of 19 owners reported their compliance in administering analgesics at 78.9%. Owners' subjective assessments showed that 24 of 86 (28%) dogs and 12 of 68 (17%) cats appeared painful at home.
The 4 prokinetic drugs metoclopramide, cisapride, pyridostigmine, and capromorelin do not increase fecal output or food intake in healthy New Zealand rabbits (Oryctolagus cuniculus).
Every day, rabbits produced a median of 75 g (range, 9 to 145 g) of feces, 226 fecal pellets (range, 12 to 412 pellets), and 151 mL (range, 5 to 420 mL) of urine. Metoclopramide, cisapride, pyridostigmine, and capromorelin had no effect on fecal production (both weight and number of pellets), food intake, urine production, or water intake compared to placebo at 24, 48, or 72 hours after administration.
How to plan and provide general anesthesia for a troop of 98 hamadryas baboons (Papio hamadryas) for contraceptive and preventative health interventions.
A group of 12 veterinarians, 2 zookeepers, and 6 volunteers anesthetized all animals within 2 days. The baboons were orally premedicated with midazolam (0.1 to 0.5 mg/kg) and anesthetized with medetomidine (40 to 60 µg/kg, IM) and ketamine (2 to 4 mg/kg, IM); isoflurane at rates of 1.5% to 2% was used for maintaining anesthesia if necessary. For population management, the animals received a contraceptive implant (adult females), orchiectomy (young males), or vasectomy (breeding males).
Head tilt in 6 Ankole-Watusi cattle (Bos taurus ankole) with chronic exudative cornual sinusitis.
Clinically, 4 of the 6 cases had concurrent otitis at the time of initial clinical observation. Medical management was the standard across all cases with limited surgical success in 2 cases. Due to intractable and progressive clinical signs despite treatment attempts, euthanasia and postmortem examinations were performed.
