Carprofen induced the lowest frequency of gastrointestinal adverse effects, followed by meloxicam. Monitoring for adverse effects should be considered when nonsteroidal anti-inflammatory drugs are used to treat dogs with chronic pain.

This study evaluated the adverse effects of oral firocoxib in dogs. Six dogs (20.2+/-6.3 kg) were studied. Values for complete blood count (CBC), serum urea, creatinine, alanine transaminase, alanine phosphatase, gamma-glutamyl transferase, occult blood in feces, platelet aggregation, and buccal mucosal bleeding time were measured before and 7, 14, 21, and 29 days after SID treatment with firocoxib 5.3+/-0.34 mg/kg (FG) or lactose 1 mg/kg (LG) for 28 days, in a randomized crossover study. Gastrointestinal (GI) tract endoscopy was performed before treatment began and at 29 days. Lesions were scored from grade 0 to 6. Data were analyzed using anova and paired t-tests (P<0.05). None of the dogs presented adverse clinical effects. There were no significant changes in CBC, biochemical profiles within groups, or differences between groups. Pretreatment mean+/-SD bleeding time (LG, 70.7+/-32.1 sec; FG, 75.8+/-38.1 sec) and platelet aggregation (LG, 86.4+/-10.2%; FG, 85.6+/-9.2%) were not significantly different from readings at 29 days (LG, 95.2+/-25 sec; FG, 91.7+/-24 sec and LG, 73.2+/-15.1%; FG, 84+/-10.3%) nor the groups were different. None of the dogs had positive fecal occult blood tests, and endoscopic lesion scores were grade 0 both before treatment and at 29 days. Administration of firocoxib did not cause any adverse effects on GI, or hematological or serum biochemical variables and appears to have been well tolerated by dogs.

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.

ABSTRACT.A case admitted at the Small Animals Clinics Service, Veterinary Hospital, FMVZ -UNESP, in May, 1999 is described. A Brazilian Terrier dog, 3 years and 3 months old, weighing 1.7 kg was brought after 2 hours and a half from contact with a scorpion (Tityus bahiensis). The dog showed vocalization inserted with drowsiness. Physical examination showed slightly hyperemic mucous, pain, agressiveness, tachypnea, tachycardia, and discrete erythema on the right forelimb palmar face. An anesthetic block was performed around the stung area using 2% lidocaine hydrochloride without vasoconstrictor (10mL). The animal was asymptomatic, after 24 h treatment.

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.
