Epidemiological evaluation of the dogs with oral tumors attended in the Veterinary Hospital of Federal University of Rio Grande do Sul

Os tumores orais em cães representam cerca de 6% de todas as neoplasias dessa espécie. O objetivo deste trabalho foi realizar um estudo epidemiológico dos cães com tumores orais atendidos no Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul durante o período de julho de 2003 a julho de 2007. Realizou-se a pesquisa nos arquivos do Laboratório de Histopatologia e nas fichas clínicas dos animais, para avaliação de dados como raça, sexo, idade e o tipo histológico dos tumores. Procedeu-se à análise de 79 cães, dentre os quais 39 (49,37%) eram machos e 40 (50,63%) eram fêmeas, com idades variando entre um e dezesseis anos (média de 7,7 anos). Os cães mais acometidos foram os sem raça definida, com dezesseis casos (19,76%), seguido pela raça Poodle, com doze casos (14,82%). As neoplasias malignas representaram 50,63% dos casos e as benignas 49,37%%. Os tumores mais comumente encontrados foram o melanoma e o épulis acantomatoso, com dezenove casos cada (23,46%), seguidos pelo fibrossarcoma e o épulis fibromatoso, com nove casos cada (11,11%), plasmocitoma com oito casos (9,88%), ameloblastoma com quatro casos (4,94%), carcinoma epidermoide e osteossarcoma com três casos cada (3,7%). Por meio deste estudo, verificou-se que os tumores malignos apresentam uma maior incidência, e os tipos histológicos mais frequentes foram o melanoma, o fibrossarcoma, o épulis acantomatoso e fibromatoso.Oral tumors reach about 6% of all the neoplasm in dogs. The objective of this research was to form an epidemiological study on dogs with oral tumors that have been treated at the Veterinary Hospital of Federal University of rio Grande do Sul from July 2003 to July 2007. The research was conducted within the archives of the histopathology laboratory, using the animals’ clinical files, in which they had been categorized by breed, sex, age and the tumors’ histology. Among the total 79 dogs analyzed, 39 (49.37%) were male and 40 (50.63%) were female. The age range of the dogs spanned from 1 to 16 years, with the average age being 7.7 years. Regarding the types of dogs which were affected by tumors, the most, 16 (19.76%), were mixed breed, followed by the poodle, with 12 cases (14.82%). Malignant neoplasms were found in 50.63% of the cases, and benign neoplasms in 49.37% of the cases. The most common tumors found was the melanoma and acanthomatous epulis with 19 cases each (23.46%), followed by fibrosarcoma and fibrous epulis with 9 cases each (11.11%), plasmocytoma with 8 cases (9.88%), ameloblastoma with 4 cases (4.94%), squamous cell carcinoma and osteosarcoma with 3 cases each (3.7%). Ultimately, this study indicates that malignant tumors were more prevalent than benign, and that the most common histological types of tumors were melanoma, fibrosarcoma, acanthomatous epulis and fibrous epulis

Use of ALGaInP laser in the wound healing of experimental cutaneous lesions in rabbits

Background: Animals with extensive cutaneous lesions remain hospitalized for long periods. In addition to increasing treatment costs, this also causes stress in these animals. Low-power laser is widely used to support tissue repair processes. Its use in the treatment of cutaneous wounds has been studied, as it reduces the wound healing period and the consequences caused by the lesion. The study aimed to evaluat the wound healing process of experimental cutaneous wounds in rabbits with the use of laser therapy. Materials, Methods & Results: Ten healthy New Zealand rabbits were used in the study, which were divided in two groups (n=5). Skin biopsies were carried out on day 16 in Group 1 and on day 8 in Group 2. The animals were under general anesthesia for the experimental cutaneous lesion to be carried out. Two 1 cm2 wounds were made on the back of each animal. The lesions were measured by a pachymeter in the immediate postoperative period, then covered with sterile gauze and maintained with rubber bandages. The animals were treated only with Tramadon 3 mg.kg-1 twice a day, during 3 days. Only the lesions on the right side of the animals were irradiated regularly, on each side of the wound, at a distance of 0.5 cm from the margin. The equipment used was a 660 nm wavelength AlGaInP laser diode (Laserpulse, Ibramed), pulsed at a frequency of 20 Hz, at a dose of 3 J and stimulation time of 12 s. The left-side lesions represented the control and the treatment administered to them consisted only of a cleanse using a NaCl solution at 0.9% once a day. The measurement of the lesion area was made every two days with a pachymeter, and the macroscopic characteristics were noted on a control card. For the histological evaluation of the wound healing process, biopsy specimens were taken from the right and left lesions on the sixteenth day in G1 and on the eighth day in G2, by means of a 6mm punch. The samples were stained with Hematoxylin-eosin for the global evaluation of the tissue section, and with Masson’s trichrome for evaluation of the presence of collagen fibers in interstitial fibrosis sites. Hyperemia followed by a discreet bleeding could be observed in wounds treated with laser after its application. With regard to the wound healing area, there was no difference between treated and control animals in both groups. However, in the microscopic evaluation of G1, in relation to the histological variables, significantly higher results were found in lesions treated with laser however, in the microscopic evaluation of G1, in relation to the histological variables, significantly higher results were found in lesions treated with laser: vascular proliferation, fibroblast and collagen proliferation, as well as the presence of hair follicles. In G2, only the fibroblastic proliferation showed a significant difference (P = 0.08) in lesions treated with laser. Discussion: There was no difference in the number of inflammatory cells in this study, perhaps because the control animals underwent laser treatment of the contralateral lesion. However, the treated animals had a higher number of deposited collagen fibers than the control ones, corroborating the data mentioned in literature. The most important result found was associated with vascular proliferation, which showed a significant difference (P = 0.046). The formation of new blood vessels seems to be substantially facilitated by the laser use, because a relatively higher number of elements was found in the group irradiated by it, as similarly hyperemia and bleeding were observed during treatment. The results obtained suggest that irradiation with AlGaInP diode laser, at a dose of 3 J, acted as a biostimulative agent in the wound healing of experimental lesions. Evidence of this could be demonstrated by an accelerated cell proliferation process during the experiment. The experimental lesion, animal species selected and laser application method were adequate for the execution of this project
