Annually hundreds of crab-eating foxes (Cerdocyon thous) are referred to rehabilitation centers and zoos in Brazil. The ultrasonographic study of wildlife species is an important tool for a non-invasive and accurate anatomical description and provides important information for wildlife veterinary care. The aim of the present study was to determine the characteristics of the main abdominal organs as well as the vascular indexes of the abdominal aorta and renal arteries of crab-eating foxes (Cerdocyon thous) using mode B ultrasonography and Doppler ultrasonography, respectively. Ultrasonographic features of the main abdominal organs were described and slight differences were noticed between ultrasound imaging of abdominal organs of crab-eating foxes and other species. The bladder presented wall thickness of 12 +/- 0.01 mm, with three defined layers. Both, the right and left kidneys presented corticomedullary ratio of 1: 1 and similarly to the adrenals and the liver, they were homogeneous and hypoechoic compared to the spleen. The spleen was homogeneous and hyperechoic compared to the kidneys. The stomach presented 3 to 5 peristaltic movements per minute, wall thickness of 39 +/- 0.05 mm and lumen and mucosa with hyperechoic and hypoechoic features, respectively. Small and large intestines presented 2 to 3 peristaltic movements per minute, wall thickness of 34 +/- 0.03 mm and three defined layers with hyperechogenic (submucosa and serosa) and hypoechogenic (muscular) features. Ovaries of the female crab-eating fox were hypoechoic compared to the spleen and with heterogeneous parenchyma due to the presence of 2x2 mm ovarian follicles. Prostates of the six males were regular and with a well defined boundary, with a homogeneous and hyperechoic parenchyma compared to the spleen. Vascular indexes of the abdominal aorta (PSV: 25.60 +/- 0.32 cm/s; EDV: 6.96 +/- 1.68cm/s; PI: 1.15 +/- 0.07 e RI: 0.73 +/- 0.07) and right (PSV: 23.08 +/- 3.34cm/s; EDV: 9.33 +/- 2.36cm/s; PI: 1.01 +/- 0.65 e RI: 0.65 +/- 0.16) and left renal arteries (PSV: 23.74 +/- 3.94cm/s; EDV: 9.07 +/- 3.02cm/s; PI: 1.04 +/- 0.31 e RI: 0.64 +/- 0.10) were determined. Thus, conventional and Doppler ultrasonographic imaging provides basic information that can be used as reference for the species as well for other wild canids and it is a precise and non-invasive method that can be safely used to evaluate and diagnose abdominal injuries in these patients.

The author has verified the average depth of the mandibular fossa, in the X-ray image, using the oblique lateral transcranial technique from the right and left sides samples of each patient, which included a total of 176 patients, 87 male and 89 female. The patients were in following phases: deciduous dentítion (the patients had only deciduous teeth in the oral cavity or, if they had any permanent teeth, they could not be in occlusion), mixed dentition (the patients presented deciduous and permanent in the oral cavity) and permanent dentition (the patients had only permanent teeth in the oral cavity), until the eruption of the permanent third molars, in the region from São José dos Campos. São Paulo. Brazil. The patients were under treatment at the Dental School. UNESP (São Paulo State University). ln order to measure the depth of the mandibular fossa in millimeters an imaginary line was traced on the X-ray image, perpendicular to the other line that served as a reference, which was traced from the botton part of the articular eminence up to the tympanosquamous fissure. After the data were obtained and put in a data sheet, they underwent statistical analysis. The results showed that, in the average, the depth of the mandibular fossa in masculine sex is non-statistically signíficant larger than what was observed in feminíne sex, and the right side is larger than the left side, with significant statistical differences. However, only in permanent dentition, in masculine sex, the depth of the mandibular fossa on the right side is larger than on the left side with significant statistical differences

The Temporomandibular Joint is a noble structure of the complex mandibular, a lot of research was conducted on the to signs and symptoms of the alterations that attack those structures. ln spite of the high incidence of the DTM in children, there's little knowledge about it, wich makes difficult the treatment Desorders Craniomandibulares (DCM) or Desorders Temporomandibulars (DTM). The Temporomandibular Joint is composed basically by three elements: bones, muscles and disk, in relation to bony part, we have the fossae mandibular that is part of the temporary bone and wich houses the condyle mandibular, accomplishing the articulation among the cranium and the jaw (it leaves piece of furniture of the articulation). Our intention in that work was of verifying a possible asymmetry of the fossae mandibular on the left side and of the right side in relation to two straight line: a straight line that coincided with the plane medium sagittal and another perpendicular straight line to the plan medium sagittal. Analyzing, the fossae mandibular in 91 dry craniums of children, with age varying between four months of life intrauterina and five years, in x-rays in that the incidence was cranium-flow, we could end that: in spite of we find statistical significance in relation to that asymmetry, clinic cannot affirm that interferences on occlusion exists for that asymmetry

The response of bone metabolism is directly related to hormonal factors and mechanical stimuli that the bone is exposed. The ultrasonic energy on bone healing have been shown to be crucial for the stimulation and improvement in quality of newly formed tissue. The aim of this study was to analyze the action of low intensity ultrasound on bone healing of tibial osteotomy in rats subjected to tail suspension, through histological analysis and histomorphometry. Eighteen Rattus norvegicus albinos, Wistar, adults were divided into three groups, arranged as follows: G1 (n = 6), who remained free for a period of 15 days, G2 (n = 5), suspended by the tail for a period of 15 days and G3 (n = 7), suspended by the tail for a period of 36 days. In all three groups, both tibias were subjected to mono-cortical bone injury 4X2 mm in the medial region of the diaphysis, and the left limb was used as control and the right limb undergoing treatment with ultrasound (U.S.). The right tibia was treated with pulsed ultrasound at a frequency of 1.5 MHz, duty cycle 1:4, 30mW/cm2, for 12 sessions of 20 minutes each. Samples of tibia were subjected to histological analysis, blindly, with light microscopy and histomorphometric analysis by specific software Image-Pro 6.1. The average percentage of new bone formation were subjected to analysis of variance in subdivided parcels and multiple comparison test "Student-Newman-Keuls (SNK), with a significance level of 5%. The average values and standard deviations of the percentage of newly formed bone for the groups showed the least amount of bone repair G1t (13.62% ± 4.88%) - G1c (8.68% ± 4.16%) compared G2t groups (27.17% ± 11.36%) - G2c (10.10% ± 7.90%) and G3t (23.19% ± 5.61%) - G3c (15.74% ± 7 08%). However, the mean values and standard deviations of the percentage of newly formed bone repair in the tibia treated G2t and G3t were significantly higher when compared to the repair of tibia in the control group (G2c and G3c). Consequently, we conclude that ultrasound has helped to accelerate bone repair in both the presence and absence of cargo.

Foi atendido no Hospital Veterinário “Luiz Quintiliano de Oliveira”, o felino Nick, SRD, de quatro meses de idade, pesando 700 gramas, com histórico de trauma por arranhadura em bulbo ocular esquerdo. Ao exame físico específico, evidenciou-se úlcera profunda e prolapso de íris, sendo então indicada a enucleação. Ao exame físico geral, observou-se freqüência cardíaca (FC) de 160 batimentos.min-1, frequência respiratória (f) de 80 movimentos.min-1, tempo de preenchimento capilar menor do que dois segundos, temperatura retal (TR) de 39,2oC e mucosas normocoradas. Como medicação pré-anestésica, empregou-se acepromazina (0,04 mg.kg-1) e metadona (0,3 mg.kg-1), administradas pela via intramuscular. A veia femoral esquerda foi cateterizada com cateter 24G para administração de Ringer com Lactato de sódio (10 mL.kg-1.h- 1 ). A indução foi realizada por máscara facial tendo-se como agente o isofluorano em fluxo diluente de 100 mL.kg-1.min-1 de oxigênio a 100%, seguida de intubação orotraqueal com sonda n o 2,5 sem cuff. Seguiu-se a manutenção anestésica com a mesma mistura da indução, administrada por meio de circuito anestésico sem reinalação de gases, do tipo Baraka, mantendose o paciente sob ventilação assistida. Ato contínuo, realizou-se a técnica anestésica peribulbar de punção única inferior, utilizando-se lidocaína 2% com vasoconstritor (3mg.kg-1) associada a bupivacaína 0,5% sem vasoconstritor (0,8mg.kg-1), perfazendo um volume total de 0,3ml.kg-1 . Uma agulha 13x4,5 foi introduzida em todo o seu comprimento com o bisel voltado para a órbita, no terço lateral do fórnice conjuntival inferior da órbita esquerda, administrando-se a associação dos agentes anestésicos locais, seguida de compressão manual da área para facilitar a difusão dos mesmos. Durante o procedimento anestésico, realizou-se a monitoração da FC, f, pressão arterial sistólica (PAS), TR e saturação periférica da hemoglobina (SpO2). O tempo total de anestesia e cirurgia foi de 30 e 20 minutos, respectivamente, e a SpO2, concentração de isofluorano e TR mantiveram-se em 99±1%, 1,7±0,8% e 37,4±1,5oC, respectivamente. O plano anestésico manteve-se estável, sem a necessidade de resgate analgésico. Não houve a ocorrência de reflexo óculo-cardíaco (ROC) frente à manipulação do nervo óptico, o que pode ser atribuída provavelmente ao bloqueio peribulbar. A anestesia regional é frequentemente empregada para cirurgias oftálmicas em humanos, como a facoemulsificação, sendo que o manejo anestésico pode contribuir para o sucesso do procedimento. Pode-se concluir que, também na espécie felina, o bloqueio peribulbar pode ser uma boa alternativa para a realização de protocolos de anestesia balanceada para procedimentos oftálmicos.
