Use of platelet-rich plasma in the treatment of desmitis of distal interphalangeal joint collateral ligament in a horse

Background: Platelet-rich plasma (PRP) has been increasingly used to hasten healing of tendonitis and desmitis, allowinghorse athletes to go back to practicing sports in a shorter period of time. However, its use has rarely been reported in thetreatment of desmitis of the collateral ligaments of the distal interphalangeal joint (CL-DIP), which is based on the useof horseshoes and rest for at least six months. This paper describes the use of PRP as an aid in the treatment of CL-DIPin a horse athlete.Case: A male Criollo horse, 450 kg, about 15-year-old, used for paleteada. The animal had a month-long history of lameness, and a visual inspection revealed an increase in volume in the lateral dorsal region of the limb proximal to the coronaryband of the hoof. A specific examination of the locomotive system showed Grade III, Category 5 claudication, which became evident the beginning of the exercise and ceased after a short period. A radiographic evaluation of the distal phalanxrevealed no clinically relevant changes. Therefore, and in view of the location of the increased volume, an ultrasound scanwas performed, which showed an image compatible with an extensive hematoma in the region underlying the periopliccorium, while the CL-DIP presented swelling with large areas of hypoechogenicity. Considering the findings of the image,the physical examination and the history of the horse, desmitis of the collateral ligaments of the distal interphalangeal jointwas diagnosed. The treatment plan consisted of rest, application of a therapeutic horseshoe, and infiltration of the lesionwith platelet-rich plasma (PRP). First, however, warm compresses were applied to reduce the swelling. The PRP wasobtained by collecting whole blood from the external jugular vein, subjecting it to double centrifugation, and separatingthe supernatant blood plasma. The end product was applied to the lesion by ultrasound-guided infiltration. The horseshoewas a model...

Dioctophymatosis as cause of dyspnea in a dog / Dioctofimatose como causa de dispnéia em cão

Dioctophyme renale is a parasite of the nematode class that can infect various species, including humans and dogs. Usually, the parasite migrates to the right kidney of the definitive host. Although, aberrant migrations have been previously reported, they mainly occur without clinical manifestations. No reports of dyspnea secondary to D. renale infestation has been found in the reported literature. The aim of this paper is to report intense respiratory distress caused by the presence of the parasite in the thoracic cavity of a dog. Radiographic images revealed multiple circular structures with a cavity with a radiopaque, thick contour in the thorax, which raised the suspicion of pulmonary bullae. Ultrasound examination revealed nematode infestation in the right kidney, scrotum, and thoracic cavity. Subsequently, right nephrectomy, orchiectomy and trans-sternal thoracotomy were performed to remove the parasites. The patient exhibited recovery after the procedures.(AU)

Dioctophyme renale é um parasita da classe de nematoda que pode infectar diferentes espécies, incluindo humanos e cães. Normalmente, o parasita migra para o rim direito do hospedeiro definitivo. Embora migrações erráticas tenham sido relatadas anteriormente, estas geralmente ocorrem sem manifestações clínicas. Não foram encontrados relatos de dispnéia secundária à infestação de D. renale. O objetivo deste trabalho é relatar a presença do parasita na cavidade torácica de um cão, causando angústia respiratória. As imagens radiográficas revelaram a presença de múltiplas estruturas circulares com aspecto de cavidade e contorno espesso radiopaco no tórax, o que suscitou a suspeita de bullae pulmonar. O exame de ultra-som foi determinante na revelação de infestação múltipla por nematódeos, no rim direito, escroto e cavidade torácica. Posteriormente, como medida terapêutica, foram realizadas os procedimentos de nefrectomia direita, orquiectomia e toracotomia transesternal para remoçãodos parasitas. O paciente evoluiu clinicamente bem após os procedimentos.(AU)

Use of gamithromycin for the treatment of osteomyelitis secondary to foot rot in a sheep

Background: Lameness is one of the main causes of economic losses in sheep breeding, especially in the distal region of the limbs. Poor sanitation management, especially in terms of hygiene conditions and the introduction of animals without previous preventive care, is an important predisposing factor in sheep flocks. Interdigital phlegmon (foot rot) is a bacterial disease that causes pain, heat, edema, hyperemia in the region, and can lead to secondary processes such as osteomyelitis. This case report describes the use of gamithromycin for the treatment of osteomyelitis secondary to foot rot in a sheep.Case: An Ile-de-France ewe exhibiting signs of lameness, pain, heat, hyperemia and edema in the four digits was treated at the Veterinary Hospital of UNIPAMPA. The lesions were characterized by interdigital phlegmon, commonly known as foot rot, and the right thoracic limb was more affected, exuding a foul odor and purulent secretion. The affected limbs were treated topically with an antiseptic solution. The lesions healed completely except for the right thoracic limb, whose clinical condition worsened. Osteitis was suspected, and was confirmed by radiographic evaluation of the region. Treatment with ceftiofur was introduced, but proved to be ineffective. Nevertheless, the lesion was found to have worsened, and a new X-ray evaluation was made, which revealed dislocation of the distal phalanx as well as involvement of the middle and proximal phalanges. Thus, we decided to perform chemical arthrodesis of the distal interphalangeal joint. Before beginning this procedure, contrast X-rays were taken that revealed the development of a fistulous pathway connecting the distal interphalangeal joint to the proximal interphalangeal joint, which precluded this procedure. In view of the worsening of the condition, amputation of the distal and middle phalanges was performed, as well as scraping of the distal edge of the proximal phalanx.[...](AU)

Nanotubos de carbono: potencial de uso em medicina veterinária / Carbon nanotubes: potential use in veterinary medicine

A utilização de nanomateriais em sistemas de segurança alimentar, detecção de patógenos, proteção de ambientes, no diagnóstico e tratamento de doenças, como sistema de entrega de fármacos e na bioengenharia tecidual tem contribuído para os avanços alcançados na ciência animal. Suas propriedades físicas, químicas e mecânicas, além de seu grande potencial de associação com outros materiais contribuem para sua aplicação em diferentes campos da medicina veterinária, por exemplo, como biomarcadores, onde as propriedades eletrônicas e ópticas possibilitam a transdução de sinais, na terapia fototérmica, devido à habilidade em converter a luz infravermelha (LIV) em calor, na engenharia tecidual, graças à resistência mecânica, flexibilidade, elasticidade e baixa densidade, além de muitas outras possíveis aplicações. O objetivo deste trabalho é informar sobre conceitos, propriedades e aplicações dos NTCs, destacando sua aplicabilidade nas áreas biomédicas, com destaque para setores da medicina veterinária que já se utilizam desse material.(AU)
