ABSTRACT

O linfoma é a neoplasia hematopoiética mais frequentemente diagnosticada na clínica de pequenos animais, sendo caracterizado por uma proliferação descontrolada de linfócitos, acometendo principalmente animais idosos. Dentre os achados clínicos mais comuns da doença, a linfadenopatia periférica recebe destaque. Manifestações clínicas como perda de peso, anorexia, edema subcutâneo, êmese, massas cutâneas, disfagia, ascite e dispnéia são também frequentemente encontradas. O diagnóstico dos linfomas é de extrema importância, sendo primordial para estabelecimento do prognóstico do animal, podendo ser feito através da análise citomorfológica de amostras obtidas por punção aspirativa e avaliação histopatológica. A poliquimioterapia é realizada como protocolo terapêutico de eleição para animais com linfoma. Foi atendido no Serviço de Clínica e Cirurgia Oncológica do Hospital Veterinário da Universidade Federal de Uberlândia (HV-UFU), um Buldogue Inglês, de dois anos de idade, apresentando linfonodonomegalia generalizada e diagnosticado com linfoma difuso de grandes células. O diagnóstico foi obtido por exame histopatológico e o imunohistoquímico revelou imunofenotipagem B. O paciente foi submetido a quimioterapia, sendo escolhido o protocolo Winscosin (CHOP) de 19 semanas com remissão completa ao término do protocolo. O objetivo deste trabalho é relatar um caso de linfoma difuso de grandes células em um Buldogue Inglês de dois anos de idade com remissão completa após a realização de quimioterapia.(AU)


Lymphoma is the hematopoietic neoplasm most frequently diagnosed in the clinic of small animals, being characterized by an uncontrolled proliferation of lymphocytes, affecting mainly elderly animals. Among the most common clinical findings of the disease, peripheral lymphadenopathy is highlighted. Clinical manifestations such as weight loss, anorexia, subcutaneous edema, emesis, skin masses, dysphagia, ascites and dyspnea are also frequently encountered. The diagnosis of lymphomas is extremely important, being essential for establishing the animal's prognosis and can be done through cytomorphological analysis of samples obtained by aspiration puncture and histopathological evaluation. Polychemotherapy is performed as the therapeutic protocol of choice for animals with lymphoma. It was treated at Serviço de Clínica e Cirurgia Oncológica do Hospital Veterinário da Universidade Federal de Uberlândia (HV-UFU), a two-year-old English Bulldog, with generalized lymph node enlargement and diagnosed with diffuse large cell lymphoma. The diagnosis was obtained by histopathological and immunohistochemical examination and revealed immunophenotyping B. The patient underwent chemotherapy, and the 19- week Winscosin (CHOP) protocol was chosen with complete remission at the end of the protocol. The aim of this work is to report a case of diffuse large cell lymphoma in a two-year-old English Bulldog with complete remission after chemotherapy.(AU)

ABSTRACT

The study of articular sounds using a computerized system (SonoPAK) in patients with temporomandibular disorders (TMD) of inflammatory origin revealed an increase of vibratory energy when compared to asymptomatic individuals. The following conclusions were reached: 1. The amount of vibratory energy registered in these patients ranged from 8.50 to 57.61 Hz. The major vibrations occurred in the middle of the mandibular opening cycle; 2. The mean vibratory energy measured at less than 300 Hz was between 5.70 and 48.64 Hz and at higher than 300 Hz was between 3.70 and 8.99 Hz; 3. The peak amplitude in the patients with inflammation ranged from 0.35 to 3.96 Pascal and the peak of frequency from 83.20 to 120.20 Hz.

ABSTRACT

Unilateral surgical transposition of the masseter muscle from the masseteric fossa to the central area of the mandibular body below the molar teeth was performed in ten adult rabbits. Six months later the animals were sacrificed, the masseter muscles were dissected and then removed to be fully dried and weighed; the skull was cleaned for anatomical examination of the mandible and the teeth. It was noticed that the transposed muscles were firmly attached and functionally adapted, but underwent a drastic reduction of their weight. The smooth surface of the mandibular body which became activated by the new muscular pull was now rough and irregular due to osseous neoformation. The original area of attachment (masseteric fossa) was remodelled not only regressively but also by bone apposition (exostoses) in some sites. The dental arches kept normal, except for alveolar bone resorption next to the first molar in two animals and accentuated sagittal deviation in another one.

ABSTRACT

With the aim of studying in the fibrous structure of the compact bone, as revealed by the split-line technique, unilateral surgical transposition of the masseter muscle from the masseteric fossa to the central area of the mandibular body below the molar teeth was performed in seven adult rabbits. Six months later the animals were killed, their mandibles were removed, cleaned and then decalcified. Split-lines were made on the lateral surface of both the control and the operated side of the mandible. Myotransposition induced alterations in the split-line patterns; they showed to be entangled and disorganized, which mean structural changes in the bone itself.

ABSTRACT

Taurodontism does not involve molar teeth exclusively. To call attention to the occurrence of this phenomenon in premolars, 4,459 extracted mandibular and maxillary premolars were examined. Eleven showed evidence of taurodontism. Roentgenograms taken from a buccolingual direction confirmed the diagnosis of taurodont teeth.
