Author Abstract

A 5-year-old gelding used for showing was presented for surgical repair of a full-thickness 15 mm diameter defect in the right pinna, which had occurred as a delayed complication following laser excision of a sarcoid. The defect had resulted in progressive deformity of the ear, and the horse was considered at risk of further injury if the defect became entrapped on a fixed object. Two artificial dermis meshes were inserted to encourage the formation of granulation tissue across the defect, and a commercially available skin expander was implanted adjacent to the site. Eighteen days later, a second surgery was performed to remove the skin expander and to mobilise a local rotational skin flap to close the defect. Both surgeries were performed under standing sedation and local anaesthesia. The site healed well, avoiding further potential trauma to the ear and deformity due to tissue contracture at the site, although some deformation of the lateral aspect of the cartilage remained.

Canine distemper outbreak and laryngeal paralysis in captive tigers (Panthera tigris).
All suspected and confirmed cases of CDV infections were significantly associated with laryngeal inflammation, which developed into paralysis in almost 50% of cases. Altogether, 50% of all tiger cases with chronic infection developed stridor at 314 days after virus infection. Therefore, laryngeal paralysis may result from CDV infection and degeneration, potentially affecting the peripheral and central nervous systems. This condition could pose a life-threatening risk to tigers.

[Disease Caused by Filoviruses: An Update].
The Marburg and Ebola viruses belong to the Filoviridae family and are known to cause emerging zoonotic diseases. These viruses have a high case fatality rate and are easily transmissible from person to person, which makes them capable of triggering outbreaks, including in non-endemic regions, and are also considered agents of bioterrorism. This review aims to improve clinical knowledge and the approach to suspected cases of FD. Improved surveillance and preparedness for potential global outbreaks are essential measures to effectively respond to these public health threats and to ensure that healthcare professionals are well-informed and prepared to deal with these diseases.

Insights into breeding management and contraception in catteries - What we learned from an online survey.
Progestin pills (n = 235, 47.4 %) were most commonly administered in queens, followed by deslorelin implants (DSRI) (n = 53, 10.7 %). Regarding tomcats, the slight majority of breeders (n = 229, 53.3 %) did not use contraceptives, next common were DSRI (n = 141, 32.8 %). Within the study population, contraceptives were most popular in (Northern) Europe, while least common in Northern America.

Cryptorchidism in dogs and cats presented for elective gonadectomy: A descriptive cohort study of 306 animals treated between 2018 and 2023.
5,476 dogs and 11,559 cats were presented to the same facility for elective surgical castration, suggesting a cryptorchid incidence of 3.21 % for dogs and 1.12 % for cats. Cryptorchid testes were more commonly observed in the inguinal area than in the abdomen, and were more frequently located unilaterally on the right side in both dogs and cats.
