Abstract

PRACTICAL RELEVANCE:Traumatic injury of the urinary tract may be caused by external accidental trauma or due to iatrogenic injury (typically as a result of catheterisation procedures). Thorough patient assessment and careful attention to patient stabilisation are essential, with diagnosis and surgical repair delayed until the patient is stable, if necessary. Treatment depends on the location and severity of the trauma. If diagnosed and treated promptly, the chance of survival of a patient without other concurrent injuries is good.

CLINICAL CHALLENGES:Following accidental trauma, at the initial presentation urinary tract injury can be overshadowed by other injuries, but if left undiagnosed or untreated it can lead to serious morbidity and potentially mortality. Many of the surgical techniques described for management of urinary tract trauma can be associated with complications, and so comprehensive communication with the owners is necessary.

PATIENT GROUP:The main population affected by urinary tract trauma is young, adult male cats, owing to their roaming behaviour, as well as their anatomy and the resulting increased risk of urethral obstruction and its associated management.

AIMS:This article aims to serve as a guide to all veterinarians who treat cats for the diagnosis and management of urinary tract trauma in cats.

EVIDENCE BASE:This review summarises the current knowledge available from a number of original articles and textbook chapters in the literature that cover all aspects of feline urinary tract trauma, and is supported by the authors' own clinical experience.

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.

The Ideal Canine Companion: Re-Exploring Australian Perspectives on Ideal Characteristics for Companion Dogs.
The ideal dog was characterised as medium-sized, with a short- low- or non-shedding coat, and acquired as a puppy from a shelter/rescue. Desired traits included being affectionate, healthy, non-aggressive, safe with children, housetrained, non-destructive when alone, and not prone to escaping.

Duration of efficacy and effect of implant location in adult queens treated with a 9.4 mg deslorelin subcutaneous implant.
The average duration of action of the 9.4 mg deslorelin implant was 790 ± 155 days (range 525-1140 days) with no significant difference in duration or efficacy depending on implantation sites. The 9.4 mg deslorelin implant causes pharmacological sterilization for about 2 years in female cats, is fully reversible, and caused no clinically relevant side effects when administered at both interscapular and periumbilical sites.

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.

Mass rabies exposure of veterinary health care workers in Germany: Management, immune response, and tolerability of post exposure-prophylaxis.
In 2008, Germany was declared free from terrestrial rabies by the WOAH. However, illegal pet imports can still lead to rabies exposure, as seen in the 2021 case of a rabid puppy illegally imported to Germany, resulting in a mass exposure (39 veterinary clinic staff) incident.
