Non-strangulated acquired hernias in stallions are rare, especially when the herniated content is not intestinal loops. Thus, the aim of the current study is to describe a case of acquired non-strangulated inguinoscrotal hernia in a stallion, whose herniated content was the omentum. The patient was a Criollo stallion with history of rhabdomyolysis, laminitis and bilateral scrotal volume increase observed in the left scrotal region. The animal presented pain in both thoracic limbs, abnormal blood test, especially hypoproteinemia, and mild pain during palpation in the left inguinal ring region. Hydrocele secondary to hypoproteinemia was suspected. After admission, the animal showed signs of acute abdomen, which were clinically reversed. With this, the animal was subjected to ultrasound examination of the scrotal region, whose findings suggested non-strangulated inguinal hernia, although the content could not be identified. Surgical treatment was chosen in order to identify the herniated content and remove the left testicle. Access to the affected scrotum was performed, in which the presence of fluid and a portion of the omentum was observed surrounding the testis and adhering to it. The animal was discharged after he recovered from the surgery and from laminitis. During the breeding season, the stallion remained with a herd of mares for natural mating. After 15 months of surgery, the animal was reassessed and showed no active signs of inflammatory and degenerative processes in the remaining testis. On this occasion, a pregnancy diagnosis was also performed, and all the mares were pregnant. It is concluded that the presence of omentum as a herniated content does not represent a surgical emergency but can make the reproductive prognosis reserved. In addition, removal of the affected testicle can benefit the spermatogenesis of the remaining testicle.
Equine-assisted therapy is a method used since ancient times to rehabilitate individuals. The biomechanics provided by horses and the friction between their back and the riders’ saddle generate impulses that are transmitted to riders’ central nervous system; thus, these horses must be healthy enough to enable the desired therapeutic effect. The aim of the current study is to investigate lameness prevalence and intensity in equine-assisted therapy horses in Rio Grande do Sul State. The adopted methodology consisted of the objective evaluation of lameness based on Lameness Locator® wireless inertial sensors, which were placed in the 21 horses assessed in six equestrian centers in Rio Grande do Sul State. Results have shown that 90.1% of the assessed horses presented lameness in the hind (54.2%) and forelimbs (45.8%), as well as that 72% of them with presented mild lameness degree. This outcome has evidenced the need, and significance, of assessing these horses’ locomotor system. To support effective therapy and protect equine welfare, it is essential that veterinarians should regularly monitor these animals in order to treat and prevent disease. Even subtle lameness can influence the generated stimuli; thus, it is an important factor to be taken into consideration when selecting equine-assisted therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
