Foram revisados os dados de 138 equinos com laminite, atendidos no período de dez anos. Destes, 48 casos de laminite crônica foram selecionados com o objetivo de relacionar a recuperação clínica dos cavalos com a utilização de dois métodos diferentes de distribuição de apoio sobre os cascos: palmilha de isopor e palmilha de isopor associada ao ferrageamento. Os cavalos foram divididos de acordo com a recuperação clínica, método de distribuição de apoio escolhido e grau de rotação da terceira falange. Também foi estabelecido o tempo médio de tratamento. Considerando os graus de rotação 3 a 5, 6 a 8, 9 a 11 e acima de 11, e comparados os dois métodos de distribuição de apoio sobre os cascos, não foi observada diferença estatística na porcentagem de animais com recuperação clínica. Contudo, dos animais que utilizaram palmilha de isopor, 43,5 ± 14% recuperaram-se clinicamente, e nos que utilizaram palmilha de isopor associada ao ferrageamento, obteve-se 69,5 ± 19% de recuperação clínica. Não houve correlação entre o aumento do grau de rotação da terceira falange e tempo de tratamento. Também a recuperação clínica dos animais não teve relação com tempo de tratamento. A literatura correlaciona vários fatores ao prognóstico, porém, neste trabalho demonstrou-se que a o retorno à função anteriormente exercida pelo cavalo não está relacionado ao tempo de tratamento, contudo, sofre influência da utilização do método de ferrageamento. | Data from 138 horses with laminitis treated in the period of ten years were reviewed. Of these, 48 cases of chronic laminitis were selected in order to relate the clinical recovery of horses using two different methods of distribution of body weight on the hooves: foam pad and foam pad associated with shoeing. The horses were divided according to clinical recovery, the weight distribution method chosen and degree of rotation of the third phalange. Also the average time of treatment was established. Considering the degrees of rotation 3-5, 6-8, 9-11 and above 11, and comparing the two methods of distribution of body weight on the hooves, there was no statistical difference in the percentage of animals with clinical recovery. However, 43.5 ± 14% of horses that used foam pad and 69,5 ± 19% of them that used foam pad associated with shoeing recovered clinically. There was no correlation between the increase of the degree of rotation of the third phalanx and treatment time. Clinical recovery of animals was not related to treatment time. Several factors are correlated with prognosis in the literature, but this study demonstrated that the return of the function previously performed by the horse is not related to treatment time, however, is influenced by the use of shoeing.

Com o objetivo de avaliar a ultrassonografia torácica (incluindo a ecocardiografia) como método de exame complementar em pacientes portadores de efusão pleural e/ou pericárdica, realizou-se a ultrassonografia torácica em 30 cães, machos e fêmeas de raças e idades variadas. Animais atendidos nos serviços de Pronto-Atendimento, Clínica Médica ou Clínica Cirúrgica do HOVET/USP com efusão pleural e/ou pericárdica, detectadas por meio de exame radiográfico, ultrassonografia emergencial ou toracocentese exploratória foram incluídos no estudo. Observou-se efusão pleural em 12 cães (40%), efusão pericárdica em oito (26,66%) e efusão pleural e pericárdica em outros dez cães (33,33%). A causa da efusão pleural e/ou pericárdica foram avaliadas ultrassonograficamente como sendo: nódulo/tumor cardíaco (5 - 16,66%), nódulo/tumor intratorácico (5 - 16,66%), insuficiência cardíaca congestiva por cardiomiopatia dilatada (4 - 13,33%) ou endocardiose de mitral e tricúspide (3 - 10%), efusão pericárdica idiopática (3 - 10%), linfossarcoma (2 - 6,66%), piotórax (2 - 6,66%), ruptura diafragmática (1 - 3,33%), hérnia peritônio-pericárdica (1 -3,33%), pneumonia e pleurite (1 - 3,33%), tumor de ovário com metástases torácicas (1 - 3,33%), pericardite infecciosa (cinomose) (1 - 3,33%) e hipoalbuminemia (1 - 3,33%). Concluiu-se que a ultrassonografia torácica demonstrou ser um excelente método diagnóstico auxiliar nos casos de efusão pleural e / ou pericárdica, além de ser não invasivo e seguro para o paciente, permitindo guiar punções com segurança e realizar o exame em diferentes decúbitos, evitando assim o estresse do paciente. | To evaluate diagnostic accuracy of thoracic ultrasonography (including echocardiography) of patients with pleural and/or pericardial effusion, thoracic ultrasonography was performed in 30 dogs, males and females, of different breeds and ages. The animals were admitted to the Emergency, Internal medicine or Surgery department of the Faculty of Veterinary Medicine, University of São Paulo, presenting with pleural and/or pericardial effusion, diagnosed by thoracic radiography, emergency thoracic ultrasonography or exploratory thoracocentesis. Twelve (40%) dogs had pleural effusion, 9 (30%) had pericardial effusion and 9 (30%) had both pleural and pericardial effusions. The definitive cause of effusion were obtained by thoracic ultrasonography as follows: heart mass (5 -16,66%), intrathoracic mass (5 - 16,66%), congestive heart failure by dilated cardiomyopathy (4 - 13,33%) or mitral and tricuspid insufficiency (3 - 10%), idiopathic pericardial effusion (3 - 10%), lymphosarcoma (2 - 6,66%), pyothorax (2 - 6,66%), traumatic diaphragmatic hernia (1 - 3,33%), congenital peritoneopericardial hernia (1 - 3,33%), pneumonia and pleuritis (1 - 3,33%), ovarian neoplasia and thoracic metastasis (1 - 3,33%), infectious pericarditis (distemper) (1 - 3,33%) and hypoalbuminemia (1 - 3,33%). The conclusion was that thoracic ultrasonography was an excellent auxiliary exam in animals with pleural and/or pericardial effusion, and it's not invasive and safe for the patient, allowing to guide biopsies and perform the exam in different decubits, avoiding patient stress.

The primary objective of this study was to determine whether or not Spiroplasma mirum would be capable of producing lesions of transmissible spongiform encephalopathy (TSE) when inoculated in raccoons (Procyon lotor) and, if that was possible, to compare the clinicopathological findings with those of transmissible mink encephalopathy (TME) in the same experimental model. For this purpose, 5 groups (n 5 5) of raccoon kits were inoculated intracerebrally with either S. mirum and/or TME. Two other groups (n 5 5) of raccoon kits served as sham-inoculated controls. All animals inoculated with TME, either alone or in combination, showed clinical signs of neurologic disorder and were euthanized within 6 mo post-inoculation (MPI). None of the carcasses revealed gross lesions. Spongiform encephalopathy was observed by light microscopy and the presence of abnormal disease-causing prion protein (PrPd) was detected by immunohistochemistry (IHC) and Western blot (WB) techniques in only the raccoons administered TME. Raccoons inoculated with Spiroplasma, but not administered TME agent, were euthanized at 30 MPI. They did not show clinical neurologic signs, their brains did not have lesions of spongiform encephalopathy, and their tissues were negative for S. mirum by polymerase chain reaction (PCR) and for PrPd by IHC and WB techniques. The results of this study indicate that Spiroplasma mirum does not induce TSE-like disease in raccoons.
