RESUMO -O linfoma é uma neoplasia com origem nos tecidos hematopoiéticos sólidos e é um dos tumores mais freqüentes em cães. Os resultados dos exames laboratoriais obtidos foram retirados dos prontuários de 54 cães com diagnóstico de linfoma, atendidos num período de 28 meses (fevereiro de 1997 a maio de 1999) no Hospital -Botucatu -SP. O objetivo foi descrever as alterações hematológicas, do exame de urina e do perfil bioquímico sérico nestes cães. As alterações hematológicas mais freqüentes foram anemia e leucocitose, que ocorreram em 44,44% dos casos. As alterações do exame de urina e do perfil bioquímico sérico foram infreqüentes. O aumento sérico da bilirrubina e das enzimas hepáticas sugerem invasão do fígado por células neoplásicas. A hipercalcemia e hiperglobulinemia foram as síndromes paraneoplásicas suspeitas neste estudo. Conclui-se que os achados bioquímicos e hematológicos do linfoma canino são inespecíficos e variados.Palavras chave: cão, linfoma, perfil bioquímico, hematologia, urinálise.ABSTRACT -Canine lymphoma, one of the frequently detected tumors in dogs, is a neoplasia originating in lymphoid tissues. Over a period of 28 months (February 1997 -May 1999) the hematologic, urinalysis and biochemical alterations of 54 dogs with a clinical diagnosis of lymphoma were evaluated at the Veterinary Hospital -Botucatu, SP. Anemia and leukocytosis were the most frequent hematological changes occurring in 44.44% of the cases. Changes in the routine urinalysis or serum clinical chemistry were infrequent. Increased serum levels of bilirubin and liver enzymes suggest invasion of the liver by neoplastic cells. Hypercalcemia and hypergammaglobulinemia were suspected as paraneoplasic syndromes in this study. We conclude that the biochemical and hematological findings of canine lymphoma are nonspecific and variable.
RESUMO -O linfoma é uma neoplasia com origem nos tecidos linfóides sólidos e bastante freqüentes em cães. O objetivo deste trabalho foi descrever os sinais clínicos dos cães com diagnóstico linfoma citológico e/ou histopatológico, atendidos no Hospital Veterinário da FMVZ de Botucatu -SP. Os dados obtidos foram retirados dos prontuários de 54 cães com linfoma, atendidos num período de 28 meses (fevereiro de 1997 a maio de 1999) no referido hospital. A manifestação clínica mais comum foi linfoadenopatia generalizada em 87,04% dos cães. Os sinais clínicos também incluíram apatia (68,52%), perda de peso (68,52%) e hiporexia (42,59%). Os resultados permitem concluir que os sinais clínicos do linfoma canino são variados e inespecíficos.Palavras chave: cão, linfoma, sinais clínicos, linfoadenopatia.ABSTRACT -Canine lymphoma, one of the most frequently detected tumors in dogs, is a neoplasia originating in lymphoid tissues. Over a period of 28 months (February 1997 -May 1999, 54 dogs with diagnosis of lymphoma were evaluated at the Veterinary Hospital of Botucatu, SP. The objective was to describe the clinical findings of dogs with lymphomas. Lymphadenopathy was the clinical finding of highest incidence (87.04%) among the animals studied. Apathy (68.52%), weight loss (68.52%) and hyporexia (42.59%) were the most frequent clinical findings. We conclude that the clinical findings vary as a function of anatomical classification and clinical staging of the tumor.
Presentación de casos clínicos RESUMENLa distrofia miotónica de Steinert es una enfermedad multisistémica, autosómica dominante, con un amplio espectro de gravedad y manifestaciones clínicas. La forma más grave es aquella que se manifiesta en el periodo neonatal, llamada distrofia miotónica congénita. Se destaca la hipotonía global al nacer y el compromiso de la función respiratoria. Las complicaciones son frecuentes, principalmente, retraso del desarrollo psicomotor, del crecimiento pondoestatural, dificultades alimentarias y constipación. Se asocia a un mal pronóstico, con una mortalidad global de hasta un 50% de los niños gravemente afectados. Presentamos cinco casos de distrofia miotónica congénita con el objetivo de describir manifestaciones clínicas, métodos diagnósticos, tratamiento y pronóstico. Los datos existentes en la literatura sobre el desarrollo psicomotor, complicaciones y pronóstico de los supervivientes con distrofia miotónica congénita son pocos. En nuestra serie de casos, las limitaciones psicomotoras presentadas son significativas. Palabras clave: distrofia miotónica tipo 1, hipotonía muscular, insuficiencia respiratoria, mortalidad, retraso del desarrollo psicomotor. SUMMARYSteinert myotonic dystrophy is a multisystemic disease, autosomal dominant, with a wide spectrum of severity and clinical manifestations. The most severe form is one that manifests in the neonatal period, called congenital myotonic dystrophy. This condition is distinguished by overall hypotonia at birth and respiratory function compromise. Complications are frequent, mainly psychomotor development delay, growth failure, food difficulties and constipation. It is associated with a poor prognosis, with an overall mortality of up to 50% of severely affected children. We present five patients with congenital myotonic dystrophy in order to describe clinical manifestations, diagnosis, treatment and prognosis. Existing data in the literature on psychomotor development, complications and prognosis of survivors with Distrofia miotónica congénita en una Unidad de Cuidados Intensivos Neonatales: serie de casosCongenital myotonic dystrophy in a Neonatal Intensive Care Unit: case series congenital myotonic dystrophy are scarce. In our case studies, we have found significant chronic psychomotor limitations.
