Tratamento de ferida em Coendou prehensilis (Rodentia: Erethizontidae) com laserterapia e ozonioterapia: relato de caso / Wound treatment of Coendou prehensilis (Rodentia: Erethizontidae) with laser and ozone therapy: case report

O emprego conjunto da laserterapia e da ozonioterapia em feridas apresenta alto potencial benéfico para os pacientes, uma vez que contribui para o manejo da dor, tem ação anti-inflamatória e acelera o processo de cicatrização. Este relato de caso tem como objetivo apresentar o uso de terapias alternativas na cicatrização de ferida em exemplar de Coendou prehensilis. Um ouriço-cacheiro, fêmea, adulto, com peso de 4kg foi encaminhado para atendimento médico veterinário com histórico de ter sido atacado por um cão. Inicialmente o ouriço passou pelo procedimento de higienização e desbridamento da ferida, para a retirada das bordas necróticas. Adicionalmente, foram administrados clindamicina (10mg/kg), por via intramuscular (IM), uma vez por dia (SID), tramadol (4mg/kg, IM, SID), flunixin (0,3mg/kg, SID), por via subcutânea (SC), e ferrodextrano (25mg/kg, IM, SID). Apesar da terapia instituída, observou-se reincidência de crescimento necrótico tecidual, o que levou à eleição do tratamento da ferida com as técnicas de laserterapia e ozonioterapia. O emprego das terapias alternativas como adjuvante promoveu uma cicatrização satisfatória da ferida, com ausência de sinais de sensibilidade local e de infecção, bem como ausência de crescimento de bordas necróticas. O tratamento adjuvante foi eficaz e pode ser empregado em outras situações para cicatrização de ferida em mamíferos silvestres.(AU)

The use of therapy with laser beam and ozone in wounds has a high beneficial potential for patients, since it contributes to the management of pain, has an anti-inflammatory action and accelerates the cicatricial process. Due to this casuistry importance, the case report aims to present alternative therapy use for wound healing on a Coendou prehensilis. Thus, a female of C. prehensilis weighing 4kg, was sent to veterinary care. At first there was a hygiene process and debridement for necrotic edge removal. Furthermore, injected clindamycin (10mg/kg) was administered intramuscularly (IM), once a day (SID), tramadol (4mg/kg, IM, SID), flunixin (0.3mg/kg, SID), administered subcutaneously (SC) and iron dextran (25mg/kg, IM, SID). In spite of the established therapy, tissue necrotic growth was observed, which lead the wound treatment as healing by second intention, initiating an alternative therapy with laser beam and ozone. As a result, the healing was satisfactory due to the elected techniques, without signs of pain and infection. The adjuvant treatment with physiotherapy had advantageous effect and could be applied to wound healing in wild mammal animals.(AU)

Skeletogenesis of the pectoral girdle and forelimbs in embryos of Caiman yacare (Daudin, 1802) (Crocodylia, Alligatoridae)

Embryos of Caiman yacare were collected and subjected to the bone clearing and staining protocol in orderto analyze the ontogenetic patterns of ossification of the pectoral girdle and forelimb skeleton. The osseousstructure of the girdle and forelimbs of C. yacare begins to ossify starting at 30 days of incubation, withthe presence of dye retention in the scapula, coracoids, humerus, radius and ulna bones. During embryonicdevelopment, the autopodio of C. yacare has four bones in the carpus, the radial, ulnar, pisiform and carpaldistal 4+5 bone. Their ossification begins at 39 days of incubation with the radial, followed by the ulnar, and at54 days, the pisiform and the distal carpal 4 + 5. Each mesopodio has 5 metacarpi and are present 15 phalanges,two in digits I and V, three in digits II and IV, and four in digit III (phalangeal formula 2:3:4:3:2). Ossificationof the metacarpi starts at 27 days of incubation, following the sequence MCII=MCIII=MCIV>MCI>MCV.The first phalanges begin the process of ossification on day 36, continuing up to the last day of incubation.The sequence of ossification of the proximal phalanges is PPI=PPII=PPIII>PPIV=PPV, that of the medialphalanges is MPII>MPpIII>MPdIII>MPIV, and that of the distal phalanges is DPI>DPII>DPIII>DPV>DPIV.The ontogenetic pattern of the bones of the forepaw of C. yacare generally differs from that of other reptiles,although there are some similarities.
