Item Acesso aberto (Open Access) Indução do estro em cutias (Dasyprocta leporina) utilizando-se protocolos à base de prostaglandina isolada ou em associação com análogo de GnRH(FEPMVZ Editora, 2018-06) PEIXOTO, Gislayne Christianne Xavier; MAIA, Keilla Moreira; CAMPOS, Lívia Batista; OLIVEIRA, Gislaine Borba; OLIVEIRA, Maurilio Fernandes de; BRITO, Adriel Behn de; DOMINGUES, Sheyla Farhayldes Souza; SILVA, Alexandre Rodrigues; ALMEIDA, Laressa Marques deWe compared the efficiency of protocols for estrus induction in agoutis. Five females received double intraperitoneal administration of cloprostenol (5µg) on a 2-days interval; other five females were treated with intravulvar administration of 30µg gonadotrophin release hormone analogue (GnRH associated to intraperitoneal administration of 5µg cloprostenol after seven days and a new administration of GnRH analogue after two days. Every 3 days, the agoutis’ reproductive cycle was monitored by blood collection for hormonal analysis, ovarian ultrasound and vaginal cytology. Two females, originally in luteal phase, that received isolated prostaglandin presented estrous signs at 3 and 6 days after the second drug administration. From the females that received the association, two that were originally in luteal phase presented estrus at 4 days after treatment, and one other presented estrus only after 10 days. There was no significant statistical difference regarding the efficiency of treatments for estrus induction (P>0.05). We conclude that, according to the protocols tested in the study, the use of isolated prostaglandin or its association to GnRH analogue for estrus induction in D. leporine shows an efficiency limited to the females that were in luteal phase in the beginning of the treatment.Item Acesso aberto (Open Access) Long-term assessment of a modified tibial tuberosity advancement technique in dogs(FEPMVZ Editora, 2018-08) MEDEIROS, Regina Mendes; SILVA, Marco Augusto Machado; TEIXEIRA, Pedro Paulo Maia; CHUNG, Denise Granato; CONCEIÇÃO, Maria Eduarda Bastos Andrade Moutinho da; CHIERICE, Gilberto Orivaldo; PADILHA FILHO, João Guilherme; DIAS, Luís Gustavo Gosuen GonçalvesThe purpose of study was to assess long-term clinical and radiographic aspects of dogs’ stifle joints which had undergone a modified tibial tuberosity advancement technique (mTTA). A total of 15 stifles that had undergone mTTA for CCL disease of 11 patients were included in this study. Assessments involved patient’s gait analysis, cranial drawer and tibial compression tests, stifle goniometry range of articular motion, thigh and leg girth and radiographic evidence of progression of osteoarthrosis. Variables were compared between operated and healthy limbs and among moments (M0) on the early postop; (M1) 120 days postop; and (M2) approximately 5 years following surgery. A questionnaire regarding owner’s perceptions after approximately 5 years of surgery was assessed. Most dogs presented positive response to cranial drawer and tibial compression tests on operated knees. There was also decrease on goniometry and thigh girth and increase in leg girth. Radiographic evidence of progression of osteoarthritis was seen especially on the long-term follow-up (M2). On gait analysis, most animals presented some degree of lameness in different conditions, in contrast to owners’ perceptions. Osteoarthritis still develops in dogs following mTTA surgery for CCL disease. However, owners were overall satisfied with their recovery and would be willing to accept indication of mTTA for dogs with ruptured CCL.
