Vascularização arterial e venosa do linfonodo poplíteo em cães

Poplíteo lympho nodes in the dogs is placed, to the right and the left in popliteo an appointed space fossa, in distal part of the muscles femoral biceps, laterally and semi-tendinous, medially, projecting in the height of the face volume of the joint to femoro tibial e femoro patellar (joint of the knee). In this study twenty and five dogs, males and females adult, originating the Araçatuba municipal kennel had been used whose captures had been effected by the animal sanitary defense of this city. The arterial vessels destined to this structure always derive, of both the sides, the femoral artery distal volume and vary of 10 the 1, more frequently of 2 (7 times, 28%) to the right and of 6 the 2, equally more frequently of 2 (8 times, 32%). So soon as one has still to right 5 and 6 branches (3 times, 12%), 1, 7 and 10 (1 time, 4%). Relatively to the veins derived from this lympho nodes, always converges to the lateral safena vein, these vessels oscillates between 9 and 2, more frequently of 3 (6 times, 24%), to the right and of 12 the 2, more frequently of 3 (10 times, 40%) to the left. Thus, others deriving branches of popliteo lympho nodes right and that if they insert in the above-mentioned vein are in number of 2 and 5 (5 times, 20%), 4 and 6 (2 times, 8%) and 8 and 9 (1 time, 4%). In spite of, to the left side it is examined in number de 2 branches (6 times, 24%), 4 (4 times, 16%), 6 (3 times, 12%) and finishing 9 and 12 branches (1 time, 4%). The size of popliteo lympho node in seropositive dogs for Visceral Leishmaniasis can meets enters 7,8 × 3,8 × 6,1 a 50,0 × 20,7 × 28,5, in mm, being average 26,18 × 10,5 × 15,97 mm for right and 26,98 × 11,14 × 15,25 mm for left (concerning the measures dorsoventral, latero-lateral and cranial-caudal, respectively).

Avaliação clínica e parasitológica de cães naturalmente infectados por Leishmania (Leishmania) chagasi submetidos a tratamento com antimoniato de meglumina e alopurinol

Aiming to assess the efficacy of the treatment, to verify the occurrence of possible disease relapses and to search for the presence of parasites after the treatment, seven dogs naturally infected by Leishmania sp., were submitted to a treatment with meglumine antimoniate and allopurinol. For this, lymph node and bone marrow aspiration biopsies were carried out at seven moments. After the end of the six-month observation period all dogs were submitted to euthanasia. Then, spleen and liver imprints and in vitro cultures were carried out to search for amastigote forms of the parasite. All animals presented remission of the symptoms and during all the observation period no dog presented relapse of the disease, although amastigote forms of the parasite were observed in two of the animals at the end of the experiment. Thus, it was possible to conclude that the treatment promotes clinical healing but it does not eliminate the parasites completely.

Avaliação da função glomerular de cães sadios e nefropatas sob estimulação dopaminérgica

Dopamine is an endogenous compound widely used in intensive care. It has a broad spectrum of action, on the cardiovascular system and urinary tract. Increased glomerular filtration rate, renal blood flow and fractional excretion of sodium and phosphorus are expected renal effects in normal individuals, but are poorly explored in veterinary medicine. This study was conducted to evaluate the glomerular function of dogs with renal disease submitted to continuous infusion of dopamine. Different doses of dopamine were administered in healthy and nephropathic dogs. Laboratory evaluations of creatinine clearance and urinary protein/creatinine ratio were performed during and after treatments. Creatinine clearance showed dose-dependent increase in healthy dogs. In dogs with renal disease, the dose of 1μg/kg/min GFR increased slightly, without changing the urine P/C and blood pressure, while the dose of 3μg/kg/min increased urinary protein excretion.

Avaliação morfométrica, realizada pelo exame ultrassonográfico, da veia porta, veia cava caudal e aorta abdominal em cães saudáveis de diferentes pesos corpóreos

The diameters and areas of portal vein, caudal vena cava and abdominal aorta are useful measurements in dogs. These values can be easily measured by ultrasonographic exam, and variations of normality can be an important indicator of hepatic or extra-hepatic alterations. This study aimed to measure the diameter and areas of portal vein, caudal vena cava and abdominal aorta in healthy dogs, with normal corporal score, divided in groups according to the body weight, and assess whether the data are influenced by animal weight. Thirty dogs were examined and divided into three groups (Group A: ≤ 10 kg Group B: from 10.1 to 20.0 kg; Group C: ≥ 20.1 kg). To measure the diameters and areas of portal vein, caudal vena cava and abdominal aorta, the animal was kept in left lateral decubitus position and the transducer was placed on the right lateral abdominal wall, at approximately the 10 th or 11 th intercostal space, in the porta hepatis region. The diameters and areas of the portal vein, caudal vena cava and abdominal aorta were significantly lower for dogs in Group A with respect to other groups and the dogs from Groups B and C had similar results with each other. The diameters and areas of the portal vein, caudal vena cava and abdominal aorta may vary with the animal size, and reference values must be specific for small, medium and large dogs.

Prevalência das arritmas cardíacas e distúrbios de condução em cães e gatos em Botucatu, Brasil (2003-2007)

Cardiac arrhythmias are important electrocardiographic disorders in small animal medicine since some of them can cause serious situations, such as cardiac arrest and death. It's essential to recognize ECG abnormalities and the frequency they occur to improve the therapy. The aim of this study was to determine the prevalence of cardiac arrhythmias in dogs from January 2003 to April 2007 by retrospective analysis of ECGs obtained at the Veterinary Hospital at UNESP - Botucatu - SP. The most common rhythm disturbances in this population were sinus tachycardia and ventricular premature complexes in dogs and sinoventricular rhythm in cats.

Avaliação histológica e morfométrica do retalho axial oris angularis e da terapia por ondas de choque aplicados a defeito palpebral experimental em cães

Considering that the cutaneous flap can be affected by isquemic complications the extra corporeal shock wave therapy (ESWT) was described as rescue techniques. The present study was developed to analyze histological and with morfometry, twenty one skin samples treated or not with the shock wave therapy, obtained from flap's distal border, used in this study to repair eyelids' experimental defects in dogs. The flap with or without ESWT did not show any histological sign of inflammatory or atrophic alterations. Both group treated showed similar morphometrical characteristics. The ESWT with the protocol used in this study (2500 impulses at 0,15 mJ/mm 2) did not demonstrate significant clinical outcomes as a rescue technique when applied over the oris angularis flap, however results showed no signals of collateral deleterious effects.

Dermatopatias em cães: Revisão de 257 casos

The purpose of this study was to collect data on skin diseases in dogs evaluated at the Veterinary Hospital of the Northern Parana State University (UENP), in Bandeirantes, Parana, Brazil. Dermatological conditions amounted to 31.38% of all consultations in dogs, and the most common skin conditions observed were, from the most to the least common: bacterial, parasitic, fungal, immune, and keratinization disorders; general skin diseases and psychogenic conditions. The highest scoring diseases, in number of occurrences were, in descending order: Superficial folliculitis, demodicidosis, dermatophytosis, bacterial otitis, deep folliculitis, dry dekeratinization, allergic dermatitis caused by flea bites, fungal ear infections, scabies, impetigo, malassezia dermatitis, parasitical otitis, pad dermatitis, and atopic dermatitis.

Detecção de anticorpos anti-leishmania infantum syn chagasi em cães de São José do Rio Preto, São Paulo

Visceral leishmaniasis (VL) has been a widespread zoonosis in São Paulo since 1998, when the first autochthonous canine case was identified in Araçatuba. The aim of this study was to determine the occurrence of anti-Leishmania infantum syn chagasi antibodies in serum samples of 584 dogs from São José do Rio Preto, São Paulo, a non endemic area for the disease. Five dogs (0.86%) seroconverted by ELISA and one (0.17%) by immunochromatography. The indirect immunofluorescent reaction, carried out in 138 animals whose optical densities were above or close to ELISA's cutt-off point, evidenced two dogs (1.45%) with titers above 1:40. Only one dog was serum-reactive on the three techniques. Although there was not a history of displacing this animal to endemic areas, the dog had been acquired in a region with canine and human cases of VL. These results suggests that there were no autochthonous cases of canine VL in this population.

Ocorrência de anticorpos contra Leishmania spp., Neospora caninum e Toxoplasma gondii em soros de cães atendidos no Hospital Veterinário da Universidade Estadual de Londrina-Pr

The aim of this study was to detect the presence of IgG antibodies anti-Leishmania spp., Toxoplasma gondii and Neospora caninum in dogs from a Veterinary Hospital from Universidade Estadual de Londrina. Blood samples from 112 animals were obtained by jugular venipuncture to obtain sera. The samples were tested by indirect immunofluorescence to detect antibodies anti-Leishmania spp., anti-N. caninum and anti-T. gondii. Thirteen (11.61%), 25 (22.32%), and 57 (50.89%) samples were positive for Leishmania spp., N. caninum, and T. gondii, respectively. The co-presence of anti-Leishmania spp. and N. caninum was observed in 6 (5.36%), anti-Leishmania spp. and anti-T. gondii in 8 (14.7%), and anti-N. caninum and anti-T. gondii in 18 (16.07%) samples. The co-presence of anti-Leishmania spp., anti-N. caninum and anti-T. gondii was observed in 5 (4.46%) dogs. There was a higher prevalence of Leishmania in Toxoplasma and Neospora positive animals, however, these results were not statistically significant (range p = 0.052 p = 0.06). The dogs have an important role in the epidemiological cycle of these diseases, which are important in animal and public health. The northern state of Paraná is an endemic area for human cutaneous leishmaniasis, therefore, studies should be conducted to uncover the real role of dogs as reservoirs of Leishmania to humans in the state.

Avaliação de colesterol e triglicerídeos séricos em cães saudáveis suplementados com ômega n-3

The analysis of serum cholesterol and triglycerides was performed in 20 healthy mongrel dogs, 10 male and 10 female, before and after supplementation for 30 days with fatty acids of long chain polyunsaturated derived from omega-3 n (497mg docosahexaenoic acid and 780mg eicosapentaenoic acid). The serum cholesterol presented a significant reduction after supplementation in both sexes (271.6±79.8mg/dL; 236,2±67,6mg/dL, before and after supplementation respectively). Regarding serum triglycerides, there was a reduction only in females (57.8±12,1mg/dL; 45.2±7,8mg/dL, before and after supplementation respectively), with no effect of supplementation in males.

Caracterização de agravos causados por cães e gatos a seres humanos no município de jaboticabal, são paulo, durante o período de 2000 A 2009

The lack of proper control of dogs and cats population and irresponsible pet ownership are factors that favor animal attack and pose serious public health concern. The aim of the present study was to characterize the injuries caused by dogs and cats to humans in the municipality of Jaboticabal, between the years 2000 and 2009, with a view to demonstrate the importance of aggression control in reducing both the risk for rabies transmission and the number of post exposure prophylaxis administration. A retrospective and descriptive study was conducted. 3,972 out of 4,149 records of patients who sought the public health service after being attacked by an animal were analyzed. Dogs were the species that most caused injuries. In the moment of the attack, the doǵs clinical status was declared as healthy in 81.8% of records; and in 81.1% of cases this status were maintained throughout the entire observation period of the aggressor. Most of injuries were characterized by bites in hands or feet, with multiple and superficial wounds. The number of injuries was high, therefore it is crucial to implement strategies to reduce injuries caused by animal attack through health promotion, educational activities and strengthening of integration of public health and veterinary services so that the decision to institute post-exposure prophylaxis is taken with criteria and safety.

Coccidiose em cães e gatos do município de andradina, estado de são paulo, Brasil

Coccidiosis is one of the most common parasitic diseases in dogs and cats in all the world. The aim of this study was to determine the occurrence of this parasitosis in dog and cat population at the Municipality of Andradina in the State of São Paulo, from 2007 to 2009. Fecal samples from 97 cats and 93 dogs were analyzed by using the techniques of flotation in saturated sodium chloride and spontaneous sedimentation. The species were classified according to morphology of the oocysts. Cystoisospora fecal oocyst found in 71.1% (69/97) of the cats, and simple infection by C. rivolta and C. felis occurred respectively in 41.0% (16/39) and 20.5% (8/39) animals, with P ≥ 0.2319. In 39.7%(37/93) of the dogs was found positive for Cystoisospora spp. And the species C. canis identified in the largest proportion (63.9%) with P = 0.0005. From the results, we conclude that dogs and cats had high incidence of infection Cystoisospora, being C. canis and C. rivolta most observed species, respectively.
