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.

Células mononucleares da medula óssea no tratamento da ruptura total dos tendões flexores e ligamento suspensor do boleto em equino

This paper describes the case of a horse treated in a Teaching Veterinary Hospital. The sutures of the flexor apparatus associated with cell therapy, the stem cell, provided a rapid response of repair compared to other cases treated in routine of the Hospital. The association of conventional treatments with the mononuclear fraction of bone marrow significantly contributed to the reduction of the hyperextension of the metatarsophalangeal joint. Ultrasound images showed rapid fill cell and decrease in inflammation.

Pitiose nasal em equino

Pythiosis is a subcutaneous infection caused by aquatic fungi (Pythium insidiosum) which occurs in some animal species, as human beings. This paper describes an Quarter Horse, breed in Pernambuco, Brazil, who had this infection. The horse presented nodular and ulcerated lesions only in nasal mucosa and the diagnosis was made by histopathologic analysis and clinical signals. Based in the histopathologic findings and anamneses information by the owner the authors believed this is an atypical presentation of this infection caused by the contact with water offered at stable.
