Meloxicam associado ou não ao tramadol no controle da dor após ovário-histerectomia videoassistida em cadelas

The aim of this study was to evaluate the efficacy of meloxicam with or without tramadol for pain control after laparoscopic-assisted ovariohysterectomy (OVH) by two-portal access. Were selected 14 healthy dogs to perform video-assisted OVHs. The animals were divided randomly into two groups (GM and GMT). The GM group received meloxicam (0.2mg kg-1, s.i.d), whereas the GMT group received the combination of meloxicam (0.2mg kg-1, s.i.d) and tramadol (4mg kg-1, tid), both for two days after surgery. To evaluate the post-surgical pain Melbourne and EVA scales were used, and blood glucose and serum cortisol were measured. There was no statistical difference when evaluating GM and GMT groups and the Melbourne scale or the visual analogue scale VAS. Cortisol measurements did not reach values higher than the reference for the species, while blood glucose levels did not present significant statistical variation throughout the evaluation time or between groups. With these results, we concluded that the use of meloxicam with or without the tramadol at the doses and dosage schedules proposed, is effective to control postoperative pain in bitches that had undergone video-assisted OVH with two-portal access.

Gemistocytic astrocytoma in the spinal cord in a dog: a case report

Relata-se um caso de uma variante rara de astrocitoma na medula cervical, diagnosticado em cadela com sinais neurologicos progressivos, inicialmente assimetricos, de tetraparesia nao ambulatoria, com reflexos segmentares e tonus muscular normais nos quatro membros e ausencia de dor a palpacao da coluna cervical. A mielografia revelou atenuacao da linha de contraste ventral e dorsal na regiao da terceira a quinta vertebra cervical. A necropsia, foi observada massa cilindrica intramedular que se estendia da terceira a sexta vertebra cervical, a qual substituia toda a substância cinzenta da medula espinhal. No estudo histologico, observou-se substituicao da substância por manto de celulas neoplasicas arranjadas frouxamente. As celulas eram grandes e levemente arredondadas. O citoplasma eosinofilico, bem delineado, por vezes formava processos interligando as celulas. O nucleo era excentrico, redondo, oval ou reniforme, e o nucleolo evidente. Logo, as alteracoes microscopicas observadas na medula espinhal cervical foram compativeis com astrocitoma gemistocitico.

Reparo de lesão penetrante em parede torácica de cão, ocasionada por javali (Sus scrofa scrofa), com flape unipediculado de músculo reto abdominal

Penetrating thoracic wounds caused by animal bites are common in dogs and are characterized by extensive trauma and adjacent soft tissue devitalization. When the local musculature is insufficient for the reconstruction, muscle flaps can be taken to repair the thoracic defect. The aim of the present report is to demonstrate an alternative to the thoracic wall defect repair in a dog which was attacked by javali (Sus scrofa scrofa), using unipediculated flap of the rectus abdominis muscle. Based on the literature, this reconstructive technique has not yet been described. The rectus abdominis muscle flap proves to be a useful alternative for the repair of extensive and infected thoracic wall lesion in dogs.
