Eficácia da imunoterapia no tratamento de pitiose facial em equino

Background: Pythiosis in horses is a proliferative and ulcerative disease that primarily affects the skin and subcutaneous tissue of limbs, thoracic-abdominal region and head. This disease sometimes can also affect limb bones or cause tumoral masses in abdomen. Usually, the cutaneous cases are confused with habronemiasis. The disease is more common in marshy areas, places with formation of slow drainage ponds and aquatic vegetation under high temperatures. The aim of this study was to describe the development of facial lesions in a horse caused by pythiosis in Cuiaba, Mato Grosso, and, additionally to discuss relevant issues regarding the diagnosis, clinical course and response to immunotherapy treatment.Case: One five years old mare of unknown breed, created in property located in the Cerrado region, had a wound on its face difficult to be healed and non-responsive to several treatments based on ivermectin and organophosphate administrated by either topical or systemic via. The animal was assisted on the farm of origin by the veterinary team of the Clinical Medicine sector, of the Veterinary Hospital, Universidade Federal de Mato Grosso (HOVET-UFMT). on the occasion of the visit, which occurred 60 days after onset of signs, the animal showed a circular single large lesion, ulcerative with serous discharge on the right part of its face, between the eyes and nostrils. There were some necrotic foci with sinus, from which kunkers were extracted; a condition compatible with pythiosis. The diagnosis was confirmed by histology, ELISA and PCR.Discussion: Assuming pythiosis from data obtained from the survey and profile of the lesion (secretory aspect, emaciation and presence of sinus and kunkers), immunotherapy treatment was immediately applied. The advanced clinical aspects and the fact that early diagnosis and treatment are essentials to satisfactory therapeutic response were also taken into consideration for starting the treatment. The remission of signs was achieved after five subcutaneous applications with 14 days between each application. From the second application, it was observed clinical improvement and after 60 days of treatment there was almost complete remission of signs. The signs for a satisfactory response in the injury site followed the order of decreasing secretory aspect, decreasing borders, decrease the itching and bringing the edges together with the formation of a thin layer of crust on the surface. Pythiosis cases with lesions on the face and lower abdomen are commonly confused with habronemiasis by macroscopic and widespread similarity between technicians and attendants, and essential support to the diagnosis through laboratory tests, which in turn are still underutilized. In this case, the authors demonstrated the therapeutic efficacy of immunotherapy as an advantage, considering the possibility of applying it in cases of lesions in areas of difficult surgical access, treatment conditions in the field, with low cost and ease of application. Further studies approaching this alternative therapy are necessary, since side effects have been observed in some cases.

Continuous Electrical Current and Zinc Sulphate Administered by Transdermal Iontophoresis Improves Skin Healing in Diabetic Rats Induced by Alloxan: Morphological and Ultrastructural Analysis

Purpose. Evaluated the effects of continuous electrical current (CEC) or zinc administrated by transdermal iontophoresis (Zn+TDI). Methods. 120 male Wistar rats were submitted to an incision surgery at the anterior region of abdomen and distributed into 6 experimental groups with 40 animals: 3 diabetic groups and 3 normal groups, untreated and treated with CEC alone or with Zn+TDI. Each group was further divided into 4 subgroups with 10 rats each to be evaluated on the 4th, 7th, 14th, and 21st day after surgery. In each period, clinical and laboratory parameters from the animals were analyzed. Results. The analysis by optical and scanning electron microscopy showed a delay in the phases of wound healing in diabetic rats without treatment in all periods of the experiment; breaking strength (BS) was significantly reduced in skin scars of untreated diabetic rats when compared to other groups. In contrast, BS in skin scars of nondiabetic groups and diabetic rats treated with Zn+TDI showed significant increase in those, besides not presenting delayed healing. Conclusion. Electrical stimulation of surgical wounds used alone or in association with zinc by TDI is able to consistently improve the morphological and ultrastructural changes observed in the healing of diabetic animals.

Efeitos cardiorrespiratórios do butorfanol em cães pré-tratados ou não pela levomepromazina

Objetivou-se com este experimento avaliar os efeitos do butorfanol precedido ou não pela levomepromazina sobre a freqüência cardíaca (FC), as pressões arteriais sistólica, diastólica e média (PAS, PAD e PAM, respectivamente), a freqüência respiratória (f), a concentração de dióxido de carbono ao final da expiração (ETCO2), a saturação da oxihemoglobina (SpO2), o volume corrente (VC) e o volume minuto (VM), em cães. Para tal, foram empregados vinte animais adultos, clinicamente saudáveis, distribuídos igualmente em dois grupos (GC e GL). Ao GC administrou-se solução salina a 0,9% (Controle), no volume de 0,2mL kg-1, pela via intravenosa (IV). Decorridos 15 minutos, administrou-se butorfanol na dose de 0,3mg kg-1 pela mesma via. Aos animais do GL foi adotada a mesma metodologia, porém substituindo-se a solução salina pela levomepromazina na dose de 1mg kg-1. As medidas das variáveis cardiorrespiratórias iniciaram-se imediatamente antes da aplicação dos fármacos (M1). Novas mensurações foram realizadas 15 minutos após a administração da solução salina a 0,9% ou levomepromazina (M2) e 10 minutos após a administração de butorfanol (M3). As demais colheitas foram realizadas a intervalos de 10 minutos, durante 30 minutos (M4, M5 e M6, respectivamente). Os dados numéricos colhidos foram submetidos à Análise de Variância (ANOVA), seguida pelo teste de Tukey (p<0,05) para as comparações das médias. O emprego do butorfanol promoveu diminuição significativa das freqüências cardíaca e respiratória e do volume minuto no grupo previamente tratado pela levomepromazina; entretanto, essas alterações foram discretas, não comprometendo os demais parâmetros circulatórios e respiratórios.
