Ooforectomia videoassistida por acesso pré-femural em targaruga-de-ouvido-vermelho (Trachemys scripta elegans)

The usual surgical technique for accessing the coelomic cavity of chelonians through the horny shields and bone plates of plastron by using a Dremel machine (plastron osteotomy) is considered slow, traumatic, and very painful for the patient. In this paper a technique of coelioscopic-assisted prefemoral oophorectomy is described in red-eared slider. The time spent on accessing the coelomic cavity, removal of the follicles and ovaries, and anesthetic recovery was markedly decreased (three hours less) in comparison with the traditional technique. The rapid return of the patient to normal activity demonstrates an important reduction in pain at post-surgical recovery. The extra cost resulting of the use of endoscopy and a specialized veterinarian service is clearly justified by the positive results described above.

Estudo da biomecânica oclusal e da aderência da resina acrílica auto-polimerizável (polimetilmetacrilato) em fraturas de rinoteca de tucanos (Ramphastos toco)

Traction effort was applied perpendicularly to the axis of toucan beaks and for accomplishment of the essay a dynamometer was used. The beak was completely fractured when submitted to traction of 270.40 N. For fixation of the fractured beaks acrylic resin was applied using a strip of 2.0cm of width. The second beak presented resistance up to 69.75 N. The third beak was submitted to acid conditioning and resisted to force of 63.29 N. Other two new tests were accomplished the whole surface of the rhinotheca filled out. The fourth beak was not submitted to the acid attack and it resisted up to 134.40 N, and the fifth was submitted to the acid etch and it resisted up to 101.50 N. The present work did not observe statistical correlation and, consequently, differences among the procedures with previous use of acid attack and those without the use of the same.

Oral myiasis in a captive hippopotamus.

Causes of dental infections can be related to failed dental eruption, malocclusion, abrasion, fractures with or without exposure of the dental pulp, and periodontal disease. Reports of oral myiasis in megavertebrates in captivity are infrequent, perhaps due to the difficulty in observing the oral cavity in such species. This report describes a case of oral myiasis in an adult male hippopotamus in the gingival area and alveolar mucosa of the left mandibular canine tooth.
