Este trabalho teve como objetivo identificar os micro-organismos mais frequentes no sítio cirúrgico e testar as suas sensibilidades in vitro para diferentes antibióticos. Foram utilizados 35 animais submetidos a procedimentos cirúrgicos eletivos. As amostras foram coletadas com swabs na região cutânea das incisões cirúrgicas antes e após a anti-sepsia e ao final do procedimento cirúrgico. Amostras ambientais foram obtidas através de placas com ágar sangue, posicionadas sob os panos de campo durante todo o procedimento. As colônias provenientes do crescimento bacteriano foram contadas e identificadas, sendo os gêneros mais frequentes submetidos ao antibiograma pela técnica de discodifusão. Foram identificados seis gêneros distintos de bactérias provenientes do sítio cirúrgico, sendo os mais freqüente Staphylococcus spp. O antibiograma mostrou a eficiência predominante da clindamicina em todas as amostras e sensibilidade parcial à cefalexina. Foi possível estabelecer um cálculo em que a contaminação bacteriana esteve relacionada em função do tempo do procedimento cirúrgico durante a primeira hora. O estudo reafirmou a importância do conhecimento dos micro-organismos presentes em sítios cirúrgicos veterinários bem como a vigilância destes.

This work had as objective identify the microorganisms most frequently at the surgical site and test their sensitivities to different antibiotics in vitro. The study included 35 animals submitted to elective surgical procedures. Samples were collected using sterile swabs in the region of cutaneous surgical incisions before and after antisepsis and the end of the surgical procedure. The environmental samples were obtained from blood agar plates positioned under the draping throughout the procedure. The colonies from the bacterial growth were identified and counted, and the genres frequently subjected to antibiotic susceptibility by disk diffusion technique. We identified six different genera of bacteria from the site of surgery, and the most frequent Staphylococcus spp. The antibiogram testing showed the predominant efficiency of Clindamycin in all samples and sensitivity partial to Cephalexin. It was possible to establish a calculation that bacterial contamination was associated with time of the surgical procedure during the first hour. The study reaffirmed the importance of knowledge of micro-organisms present in veterinary surgical sites as well as monitoring these.

A 10-year-old DSH cat was referred for a dental evaluation and extraction procedure. Subsequently, the animal developed an acute onset of ocular discharge. Ophthalmologic examination revealed presence of unilateral ocular mucoid discharge leading to a diagnosis of epiphora secondary to nasolacrimal duct obstruction. Dacryocystorhinography was performed and confirmed the presence of a nasolacrimal duct obstruction, presumably acquired after an invasive dental procedure. Additionally, a vinyl cast in situ study of the nasolacrymal apparatus was performed to demonstrate the route of the nasolacrimal duct in the cat and its relationship to oral dental structures. This report documents an unusual case in which excessive inflammation/edema following tooth extraction caused acute epiphora secondary to extraluminal compression of the distal nasolacrimal duct.

Chemical restraint of large felids is necessary for the handling, transportation, clinical assessment, and induction of anesthesia. The objective of this study was to evaluate the efficacy and safety of chemical restraint using a combination of tiletamine, zolazepam, detomidine, and atropine with interspecific allometric scaling doses in captive Panthera onca. There were ten males (two melanistic ones) and five females weighing between 35 and 80 kg. The evaluation of the chemical restraint protocol was carried out during routine management of the animals for physical examination, collection of blood and bone marrow samples, dental evaluation, and other procedures. During pre-established intervals, rectal temperature, heart rate, respiratory rate, nociception of thoracic and pelvic limbs, muscle relaxation and loss of the righting reflex were monitored. Loss of the righting reflex occurred at 8 ± 1.89 minutes post-injection (MPI). Respiratory rate returned at 77.6 ± 8.18 MPI; return of consciousness occurred at 112.6 ± 12.28 MPI, and complete recovery at 153 ± 12.47 MPI. There were no statistical differences between heart and respiratory rate means and oxyhemoglobin saturation. For rectal temperature, there was a significant reduction. The protocol analyzed was efficient for the chemical restraint of jaguars, enabling the manipulation, transportation, physical examination, dental evaluation, blood and bone marrow sample collection, and other minor invasive procedures of medium duration in these animals.

Dentre 970 casos de neoplasias diagnosticados entre abril de l974 e março de l996 no Serviço de Patologia do Hospital Veterinário da Universidade Federal do Paraná, 28 casos (2,88%) ocorreram em animais selvagens ou exóticos. Dezoito desses animais eram mamíferos (seis hamsters, quatro camundongos, dois coelhos, uma cutia, uma cobaia, um macaco prego, um lobo guará, um puma e um leão) e 9 eram aves (dois canários belgas, dois papagaios, dois periquitos australianos, uma marreca irerê, um lóris negro e um sabiá laranjeira). Destes, 17 casos (60,7%) eram de neoplasias malignas, sendo seis linfossarcomas, três carcinomas espinocelulares, três carcinomas indiferenciados, um fibrossarcoma, um hemangiossarcoma, um sarcoma indiferenciado, um seminoma, um adenocarcinoma de glândula sebácea e um adenocarcinoma indeterminado. As neoplasias benignas somaram nove casos (32,1%), sendo dois hemangiomas, dois lipomas, dois fibromas, um adenoma hepatocelular, um papiloma e um tricoepitelioma. Além disso, registraram-se dois casos (7,0%) de carcinomas basocelulares, considerados mais como localmente agressivos do que como malignos. Abstract From 1974 to 1996, 28 cases of neoplasia were diagnosed in wild or exotic animals at the Service of Animal Pathology, Veterinary Hospital, Federal University of Paraná - Brazil, comprising 2.88% of all neoplasia diagnosed during that period. Eighteen cases (66.7%) occurred in mammals (six hamsters, four mice, two rabbits, one agouti, one guinea pig, one capuchin monkey, one manned wolf, one puma and one lion). Nine cases (33.3%) were diagnosed in birds (two domestic canaries, two amazon parrots, two budgerigars, one white-faced whistling-duck, one black lory and one rufous-bellied thrush). Seventeen cases (60.7%) were of malignant neoplasia: six lymphosarcomas, three epidermoid carcinomas, three undifferentiated carcinomas, one fibrosarcoma, one hemangiosarcoma, one undifferentiated sarcoma, one seminoma, one sebaceous gland adenocarcinoma, and one undetermined adenocarcinoma. Benign neoplasia totaled nine cases (32.1%): two hemangiomas, two lipomas, two fibromas, one hepatocelular adenoma, one papilloma and one trichoepithelioma. Additionally, two basal cell carcinomas were diagnosed. These were considered as locally aggressive, rather than malignant neoplasms.

RESUMO: Uma fêmea de coelho-anão apresentando uma membrana vascularizada exuberante cobrindo cerca de 90% da superfície corneana do olho direito foi atendida em um hospital veterinário universitário. Com diagnóstico de pseudopterígio, a coelha foi submetida a intervenção cirúrgica corretiva, com técnica baseada em incisão da conjuntiva aberrante em três secções radiais. O tecido restante foi suturado à conjuntiva bulbar com fio absorvível poliglactina 910 de calibre 6-0, empregando-se ciclosporina tópica para prevenção de recidivas. Ao exame histopatológico o tecido apresentava estroma conjuntivo normal revestido por epitélio conjuntival, sem células caliciformes. O animal se recuperou sem intercorrências e nenhum sinal de recidiva foi observado trinta dias após o procedimento.Palavras-chave: lagomorfo; oftalmologia; membrana aberrante; pseudopterígio ABSTRACT: A female dwarf-rabbit presenting an exuberant vascularized membrane covering about 90% of the corneal surface of the right eye was examined and treated at a veterinary teaching hospital. Diagnosed with pseudopterygium, the animal was submitted to corrective surgery based on incision of the membrane in three radial sections. The remaining tissue was sutured to the bulbar conjunctiva with 6-0 polyglactin 910. Topical cyclosporine treatment was prescribed to avoid recurrences. Histopathological analysis showed normal stroma and conjunctival epithelium with no goblet cells. The rabbit recovered with no complications and no signs of recurrences were noticed until thirty days after surgery.
