Tendinose do supra-espinhoso em cães

Supraspinatus tendinosis was recently reported in dogs but it is a well-documented disorder in human beings, specie in which is considered the cause of pain and dysfunction in 51% of cases of shoulder problems. It can cause pain and lameness or be asymptomatic in dogs. The clinical relevance in canine specie is unclear and seems to be underestimated. The aim of this paper is to review the possible etiologies involved in this tendinopathy, the main diagnostic methods applied and actual options of therapies in veterinary medicine. Simultaneously, call the clinicians attention to this disorder as differential diagnosis for forelimb pain and lameness diseases.

Pitiose cutânea equina de localização atípica tratada topicamente com solução de anfotericina B e DMSO

Background: Cutaneous lesions by Pythium insidiosum infection are commonly observed in horses, especially in those living at flooded environments. Equine pythiosis is characterized by the development of tumoral masses that are frequently located at distal limbs, ventral abdomen, thorax, breast and face. The lesions are usually granulomatous, serosanguineous and ulcerated, most often destroyed by self-mutilation due to the intense pruritus. The proposed treatment includes surgical excision followed by antifungal drugs administration, which can be done systemically or topically. Amphotericin B and dimethyl sulfoxide (DMSO) in association has been successfully used for cutaneous pythiosis topical treatment due to the DMSO property to carry any substance through plasmatic membranes.Case: The present report concerns a 12-year-old mixed breed gelding presenting with self-mutilation of a tumoral mass located at the left flank. The owners reported that the horse had initially presented a small wound that had evolved to a 20-cm in diameter mass in 4 weeks. Tissue samples were collected, processed and stained by the Gomori's methenamine silver (GMS) method. The histopathological analysis revealed Pythium insidiosum hyphae in a granulomatous tissue, especially located at peripheral region, where kunkers were present. Surgical excision of the mass followed by cauterization was indicated as initial treatment, and due to financial reasons, the owners elected only the topical antifungal therapy to control the fungus infection after surgery. Flunixin meglumine was also administrated for five days aiming the control of pain and inflammation. The wound was cleaned with povidone-iodine solution and rinsed with a solution containing, 50 mg, of amphotericin B in 10 mL of sterile water and 10 mL of DMSO. This procedure was carried Out twice a day. The wound healed fast due to an excellent centripetal epithelialization. and the horse was discharged after 64 days showing only 5% of the initial wound area. The owner reported by telephone the complete healing and hair growth 10 days after discharge.Discussion: Despite the atypical location of the tumoral lesion described at the present report, the history and clinical manifestations, especially the intense pruritus, showed similarity with other characteristic reports of equine cutaneous pythiosis. The diagnosis was confirmed by the histopathological examination showing hyphae structures, as described to be evidences of the presence of Pythium insidiosum in the tissue. The surgical procedure was the first step to provide remission of clinical signs, and one day after surgery the pruritus desapeared. After excision of the granulomatous tissue and cauterization, daily topical administration of amphotericin B associated with DMSO was effective in destroying the infectious agent, as observed by the excellent epithelization. A pink granulation tissue grew up providing an ideal surface for epithelial migration and the healing process progressed quickly. Centripetal epithelialization reduced the wound area until 3% of the initial area in 64 days of treatment, when the remaining wound was found almost completely healed and covered with hair. At the present report, the horse presenting pythiosis was only topically treated. The recommended therapy using amphotericin B and DMSO solution was effective, economically viable and low risk, considering that the systemic antifungal therapy usually suggested is expensive and extremely nephrotoxic. The atypical location of the lesion on the left flank shows that any anatomical region can be affected by the fungus, since the conditions for its development were present.

Alterações do padrão ultrassonográfico do parênquima testicular em bovinos jovens da raça Nelore

The ultrasononographic examination of testicles is a noninvasive and rapid method that, allied to clinical examination, can lead to an early diagnostic of testicles disorders. The aim of the present study is to enhance andrologic evaluation and to make public altered ultrasonographic testicular parenchyma pattern in young Nelore bulls. Testes of 114 Nelore bulls from 9 to 15 months old were submitted to ultrasonographic evaluation (Frontal and transverse planes of testes). In this group, 111 animals presented testicular parenchyma with uniform pattern at low echogenicity, and the testicular echogenicity increased in proportion to the animal's age. Three animals, from 9 to 15 months old, presented heterogeneous testicular parenchyma with multiple hyperechoics

Orbital cellulitis associated with Toxocara canis in a dog

Reports of Toxocara canis ocular larva migrans are uncommon in animals, with only a few cases reported. Most reports involve larval migration into the retina and choroid, with parasitic invasion of the orbit reported only in experimental studies. This is the first clinical case of Toxocara canis infection in the retrobulbar region of a 10-year-old, cross-bred male dog presenting with unilateral orbital cellulitis. Ophthalmic signs included protrusion of the nictitating membrane, chemosis, exophthalmos and hypertropia. The parasite was diagnosed by histologic and parasitologic examination of orbital tissues, which were removed during enucleation.

Rectal atresia in a newborn donkey

P>A case of a type I rectal atresia (also known as membranous rectal atresia) in a newborn donkey is reported. Clinical examination, survey radiographs and barium enema radiographs suggested rectal atresia. An exploratory laparotomy was performed; however, surgical correction of the defect was not possible due to the narrow pelvic cavity. Euthanasia was performed. At necropsy, it was possible to observe a fibrous cord connecting the small colon to a residual rectal ampulla, which opened to a normal anus. The radiographic and anatomical characteristics enabled the classification of the defect as type I rectal atresia, which is a rare congenital anomaly that is difficult to correct through surgery. This report contributes to the study of rectal atresia in newborn equids, alerts for the occurrence in donkeys and is, to our knowledge, the first to be reported in this species in Brazil.

Gastric Torsion from an Intestinal Hernia Through a Rent in the Gastrosplenic Ligament in a Horse

The present report describes an 8-year-old gelding presenting with signs of severe abdominal pain. After performing a thorough physical examination, including rectal palpation and additional diagnostic tests, an exploratory laparotomy was recommended. The jejunum was found herniated through the gastrosplenic ligament, and the stomach was severely distended with gas. Given a poor prognosis, the horse was euthanized on the table. At necropsy, the stomach appeared dilated, with an 180 horizontal gastric torsion, from left (lateral) to right (medial), dividing the organ into dorsal and ventral compartments. We believe that the chronic traction exerted by an incarcerated and distended loop of jejunum, in the dorsal aspect of the gastrosplenic ligament, associated with trauma during episodes of intense rolling, enlarged the rent until it ruptured. Because of this rupture, the lateral dorsal aspect of the stomach became unattached, predisposing it to the torsion. (C) 2012 Elsevier B.V. All rights reserved.

Influence of different fat sources on the performance, egg quality, and lipid profile of egg yolks of commercial layers in the second laying cycle

This study was designed to evaluate the effects of different fat sources on the performance, egg quality, and lipid profile of the egg yolks of layers in their second production cycle. The fat sources were cottonseed oil, soybean oil, lard, sunflower oil, or canola oil. Experimental diets were fed to postmolt ISA Brown layers at 70 wk of age and the experimental period was 74 to 86 wk of age. The different fat sources did not influence performance or eggshell quality, but lipid profile of the egg yolk changed as a function of dietary fat sources. In general, the best changes, such as lower level of saturated fatty acids, higher levels of alpha-linolenic acid and DHA, and lower linoleic acid levels, were promoted by the addition of canola oil, but it did not promote enrichment of the eggs with polyunsaturated fatty acids.

Valor energético de algumas fontes lipídicas determinado com frangos de corte

Um experimento foi conduzido para se determinar o valor energético do óleo de soja refinado, do óleo de canola refinado, do óleo de girassol refinado, do óleo de frango, do óleo de peixe e da banha suína para frangos de corte. Foram utilizados 168 frangos de corte com 22 dias de idade, distribuídos em um delineamento inteiramente casualizado, com sete tratamentos (seis fontes lipídicas e uma ração-referência) e quatro repetições de seis frangos por unidade experimental. O experimento teve duração de oito dias, sendo a coleta de excretas realizada nos últimos cinco dias. As fontes lipídicas testadas substituíram a dieta basal em 20% na matéria natural. Os valores de energia metabolizável aparente corrigidos para retenção de nitrogênio na matéria natural foram: 9.201 kcal/kg para o óleo de soja; 8.129 kcal/kg para o óleo canola; 9.561 kcal/kg para o óleo de girassol; 8.251 kcal/kg para o óleo de frango; 8.715 kcal/kg para o óleo de peixe e 8.366 kcal/kg para a banha suína.
