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)

Epidemiological aspects of the Brazilian spotted fever: serological survey of dogs and horses in an endemic area in the State of São Paulo, Brazil.

In order to obtain information on Brazilian spotted fever, a study in domestic animals was performed in the County of Pedreira, State of São Paulo, Brazil, where 17 human cases had been notified. Serum samples obtained from animals were tested by indirect immunofluorescence for detectable antibodies to spotted fever-group rickettsiae. Seropositivity was revealed in 12 (36.4%) of 33 dogs and seven (77.8%) of nine horses from the endemic area. For comparison, blood samples from dogs and horses from non endemic area were tested and four (12.9%) of 31 dogs and three (27.3%) of 11 horses were positive. The highest titers of antibodies by IFA (IgG > or = 1:1024) were found only in three dogs and six horses from endemic area. The results suggest that dogs as horses may serve as environmental sentinels for establishing the prevalence of foci of spotted fever in Brazil.

Secondary dengue infection in schoolchildren in a dengue endemic area in the state of Rio de Janeiro, Brazil.

A seroepidemiologic survey was carried out in schoolchildren from public schools of the Niterói municipality, state of Rio de Janeiro, Brazil, after a period of sequential epidemics by dengue virus type 1 and 2 (DEN-1 and DEN-2). 450 blood samples were obtained by fingertip puncture and collected on filter paper discs. The hemagglutination inhibition (HAI) test was carried out using DEN-1 and DEN-2 antigens. HAI titres were demonstrated in 66% (297/450) of the sera and the geometric means of the titres were 1/182 and 1/71 for DEN-1 and DEN-2, respectively. Secondary infections were observed in 61% (181/297) of positive cases. Among these, 75% (135/181) were under fifteen years old. No dengue haemorrhagic fever (DHF) was reported in these children. Asymptomatic or oligosymptomatic infections were detected in 56% of the studied population. The absolute and relative frequencies of positive tests by age group and sex did not evidence statistically significant difference. The number of individuals infected probably produced a immunologic barrier responsible for the non occurrence of dengue epidemic in the latter years.
