Efeitos hemodinâmicos e metabólicos imediatos determinados pelas soluções de cloreto de sódio a 7,5% e de sua associação ao dextran 70 a 6% na reanimação do choque hemorrágico: estudo experimental em cães

JUSTIFICATIVA E OBJETIVOS: O dextran associado à solução hipertônica de cloreto sódio a 7,5% apresenta efeitos hemodinâmicos benéficos no controle prolongado da reanimação no choque hemorrágico. O objetivo deste estudo foi verificar se a associação do dextran à solução de cloreto de sódio a 7,5% apresentaria vantagens na avaliação imediata dos parâmetros hemodinâmicos e metabólicos na reanimação em modelo de choque hemorrágico controlado em cães. MÉTODO: Foram estudados 16 cães submetidos à hemorragia controlada até que a pressão arterial média atingisse 40 mmHg e permanecesse assim por até 30 minutos. Estes foram divididos em G1, com administração de NaCI a 7,5%, e G2, com administração NaCI a 7,5% combinada com dextran 70 a 6%, no volume de 4 mL.kg-1, durante três minutos. Foram avaliados os parâmetros hemodinâmicos e metabólicos. Consideraram-se quatro momentos: M1 - 10 minutos após o preparo cirúrgico, M2 - obtido na metade da fase de choque, M3 - obtido dois minutos após o final da administração das soluções, M4 - 30 minutos após o início da reanimação. RESULTADOS: Após a reanimação, não houve diferença significativa dos valores da FC, PAM, PCP e IRVS. O G2 apresentou valores maiores do IC em M4. Os valores da SvO2 foram menores no G1, final do experimento. A C(a-v)O2 foi maior no G1 nos momentos M3 e M4. Os valores do VO2 aumentaram nos dois grupos em M4 e os valores do lactato plasmático aumentaram progressivamente até M3 e diminuíram em M4. Houve aumento dos valores do Na plasmático e redução do hematócrito nos dois grupos. CONCLUSÕES: O G2 mostrou melhor desempenho hemodinâmico principalmente após 30 minutos do início da reanimação. Observou-se, também, maior expansão plasmática e melhor perfusão tecidual na associação do dextran ao NaCl a 7,5%.

Follicular thyroid carcinoma in dogs. Report of cases

The treatment of choice for these cases was surgical removal. In both cases the diagnostic was infiltrative follicular carcinoma of thyroid. The first animal did not present a good recovery after the surgery, and died four hours after the procedure. In the second case, the diagnosis was more precocious and antineoplastic chemotherapy was used after the surgery. At the time of submission of this manuscript, this animal had survived for foully months. Currently, there is a need to define the protocols of chemotherapy to avoid relapse and metastases, in order to increase the life expectancy in dogs with thyroid neoplasm.

Comparación de la conductancia hidráulica dentinaria, de acuerdo al tiempo de aplicación de desensibilizantes con base de oxalatos

ABSTRACT. Introduction: an in vitro model was used to measure the hydraulic conductance in human dentin discs treated with oxalic acid for 15, 30 or 60 s maintaining the occlusive effect and measuring 7 and 14 days after application. Methods: 45 dentin discs measuring 1 mm thick were obtained from human third molars which were free of caries and in no occlusion; the samples were obtained from patients aged 16 to 30 years. Discs were sorted out into three study groups (n = 15) depending on the time of application of a commercial solution of oxalate-based dentin desensitizer (DD) (BisBlock®) which contains ˂ 5% oxalic acid of 1.5-1.8 pH: in group A the agent was applied for 15 s, in group B it was applied for 30 s, and in group C for 60 s. The hydraulic conductance of each disc was calculated after acid etching, which corresponds to the maximum permeability of discs (100%) after immediate application of oxalic acid, as well as seven and fourteen days of storage in saline solution. The statistical analysis was done with ANOVA test and post-hoc Games-Howell test. Results: 35,46 ± 23.41% in Group A, 36.34 ± 15.88% in Group B and 24.99 ± 14.99% in Group C, showing that the use of DD for 15, 30 or 60 s decreased permeability in a statistically significant manner (p <0.05). Conclusions: DD was effective in reducing hydraulic conductance regardless of application time, but this reduction was temporary only, since after seven days permeability returns to values close to those of baseline.

Conscientizar para o bem-estar animal: posse responsável

The community awareness on responsible ownership associated with public policies is key to the promotion of animal welfare. Most cities have a large population of dogs and cats wandering causing serious health problems and abuse. This project aimed to guide and inform the population aimed at animal welfare with the simple and direct approach to issues related to responsible ownership, management, nature conservation and zoonoses. The methodology developed to approach the project in two modules: the I and II, along public and private Elementary and High Schools in Araçatuba. Module I (Mod.I) is basedon the use of puppet theater and musicals, considering the target audience children 3-10 years and the second module (Mod 2) consists of presentations of lectures by undergraduate and graduate course of Veterinary Medicine FMVA UNESP campus Araçatuba, being the target audience of High School teenagers. Data collection proceeded by questionnaires, with questions regarding the care and practices to pets. The results revealed that there is a lack of information about animal welfare practice.

Orientação sobre posse responsável em uma área endêmica para leishmaniose visceral canina

The purpose of this work was to provide guidance to householders in the responsible care of their pets, in a region where canine visceral leishmaniasis is endemic. Questionnaires on responsible ownership and the control of this disease were completed by owners of dogs and cats in the city of Araçatuba, São Paulo State, Brazil, in order to evaluate their level of knowledge. Based on the identified deficiencies, the project team provided the owners of the pets with individual guidance at home, focusing on the most critical issues. Concerning nutrition, 70.45% (62/88) of owners provided pet food only, 27.28% (24/88) administered a mixed diet, and 2.27% (2/88) provided homemade food. Additionally, 78.41% (69/88) did not permit the consumption of raw meat, rare meat, or bones. 9.09% (8/88) of owners allowed their pets to wander the neighborhood alone. Among dogs, 14.77% (13/88) had never been clinically tested by a qualified professional, and 6.82% (6/88) and 15.91% (14/88) had never received any kind of vaccine or vermifuge, respectively. In relation to population control, only 20.45% (18/88) of the dogs had been sterilized. It was also observed that 25% (22/88) of owners had already had canine visceral leishmaniasis seropositive dogs in their homes. 54.55% (12/22) of these owners had referred their pets to veterinary clinics for euthanasia, 22.73% (5/22) had used the services of the city’s animal disease control center, and 18.18% (4/22) had paid for private treatment. Nevertheless, 35.23% (31/88) of the dogs had never been submitted to tests for infection diagnosis. From the results obtained, it could be inferred that the individuals who participated in this study were poorly informed concerning basic pet care, demonstrating a need to implement community awareness campaigns for the responsible ownership of pets.

Epidemiological aspects of dog bites considering biter dogs and victims

The aim of this study was to characterize dog bites using data on biter dogs and victims. An exploratory cross-sectional study was performed using 203 records of individuals who had attended in public health services in 2009 in the municipality of Araçatuba, São Paulo, Brazil, after they had been bitten by a dog. Over 70% (92/129) of the biter dogs were male and most of them (71%) received as a gift. Dog owners reported companionship as the main reason for acquiring the dog. The victims who were children were predominantly male, while the victims who were elderly were predominantly female. Most children were bitten on the head/neck, while adults were bitten on the hands/feet and lower limbs (p<0.0001). The owner of the dog was known in 83.2% of cases. However, rabies observation of the biter dog following the attack was only reported in 59.4% of cases. Situations involving aggression were related to dogs having escaped from their home (18.7%) or roaming free on the streets (17.0%). The analysis of biting dog characteristics using information obtained from dog bite victims and biting dog owners can help direct the medical treatment for dog bite victims. Moreover, concepts of responsible dog ownership can reduce the occurrence of bites.

Programa de conscientização de idosos sobre posse responsável de animais de estimação em bairro periférico do município de Araçatuba, SP

Currently, responsible ownership of pets has been widely discussed. In the past, they were brought to our society and it is our duty nowadays to establish this relationship between man and animal. This study aimed at evaluating the level of knowledge of elderly dog owners about responsible ownership with emphasis on control of canine visceral leishmaniasis and at the same time make them aware of the precautions to be taken. An individual questionnaire on the subject was applied to 68 elderly people. They all belong to Nossa Senhora Aparecida Village, located on the suburb of Araçatuba-SP. Along with the interview, veterinary students advised them on the control of canine visceral leishmaniasis, the importance of sterilization in cats and dogs and the responsible ownership, with distribution of informative leaflets. Fecal samples from dogs were collected by the owners and they were sent to the Laboratory of Parasitology and Parasitic Diseases at Odontology Faculty at Araçatuba UNESP to be processed through the Willis-Mollay technique. Anthelmintic were acquired in the project and donated for the treatment of animals tested positive. 56.25% (63/112) out of the total number of dogs examined were females, aged between one and ten years. Only 32.14% (36/112) had access to the streets, 90.18% (101/112) were not castrated and 58% (65/112) were mixed breed (SRD). Among the owners, 88.24% (60/68) did not know what zoonosis is and 14.71% (10/68) were not aware what leishmaniasis is. Regarding the researched animals, 62.50% (70/112) had ectoparasites (fleas and ticks). It was also observed that 67.86% (76/112) of dogs had been dewormed, but in 59.82% (36/112) of cases, the intervals between these processes were irregular. For females, 85.71% (54/63) had no prevention heat and it was noted that 19.51% (8 / 41) had already given birth, had dystocia. With these data we can confirm the lack of information by these elderly and the need to establish community awareness and continued programs.

Eletrocardiografia, sedação e qualidade da recuperação do butorfanol ou buprenorfina em cães pré-tratados pela acepromazina

The aim of this work was to evaluate the electrocardiography effects (ECG), sedation time and quality of recovery due to buprenorphine (G1) and butorphanol (G2) administration in dogs pretreated with acepromazine. Seven adult dogs were submitted to both protocols, with a thirty days interval between groups. G1 animals were premedicated with acepromazine (0.1 mg/kg) followed 10 minutes later with buprenorphine (0.005 mg/kg), both applied intravenously. The same procedure was performed for G2 employing butorphanol (0.3 mg/kg) instead of buprenorphine. The measurements of the variables heart rate (HR), duration and amplitude of P wave, P-R intervals (PR), QRS complex duration, R wave amplitude, Q-T intervals (QT) and R-R intervals (RR) were taken immediately before application of acepromazine (M0), 10 minute after administration of acepromazine (M10) and 10 minutes after opioids administration (M20). Serial measurements were carried out in 10 minute intervals after the administration of butorphanol or buprenorphine up to 60 minutes. Numeric data were submitted to Tukey Analysis (p < 0.05). The amplitude of P wave decreased 30 minutes after the administration of the butorphanol. Sedation time was longer in G1 (78 minutes) than G2 (72 minutes) and recovery was good in both groups. These results indicate that butorphanol or buprenorphine produced discreet alterations on ECG, which don´t contraindicate its clinical use.

Morphological, immunohistochemical and molecular study of renal lesions in canine visceral leishmaniasis (CVL)

Canine visceral leishmaniasis (CVL) is an anthropozoonosis characterized by a clinically chronic progressive disease. Non lymphoid organs are also affected, especially the kidneys. Dogs with leishmaniasis usually die with renal failure despite treatment. Haematoxylin-eosin (HE) staining in kidney tissue sections has low sensitivity for parasite identification. Immunohistochemistry (IHC) and polymerase chain reaction (PCR) are efficient methods for Leishmania sp. antigen and DNA detection in cases of low parasite burden. The present study aims to identify renal lesions of CVL and correlate them with microscopic findings determined by histochemistry, IHC and PCR. Both IHC and PCR provided similar positivity for amastigote identification, 3/20 animals (15%), thus increasing detection of the parasite in renal tissues when compared with histopathologic examination. The lesion most commonly observed with visceral leishmaniasis-positive canine kidney tissue was membranoproliferative glomerulonephritis, followed by interstitial nephritis without correlation to the number of amastigotes.

Nefroblastoma em cão de 4 meses: relato de caso

Renal nephroblastoma is a malignant tumor composed by embryonic tissue that affects mainly puppies. This works reports the occurrence of unilateral renal nephroblastoma in a puppy with four months. The diagnosis was obtained by histopathological examination of mass obtained by exploratory laparotomy, with realization of nephrectomy. The animal died at 15 days post-operatively by the presence of pulmonary metastases. The survival rate with surgical excision of the mass, with or without complementary therapies, can vary with the stage of disease.

Avaliação dos conceitos sobre posse responsável exercida pela terceira idade em instituições não governamentais de Araçatuba-SP

Pets bring expressive benefits into the life of the elderly, so it becomes necessary to emphasize some of the concepts regarding responsible ownership consisting of a set of important attitudes that accounts for the well-being of all. In this context, non-governmental institutions represent an excellent mean of communication and information. Besides, the increase of the third aged people population indicates that a survey of parameters to this respect is necessary. Being thus, the objective of this work was to analyze the aged ones´ level of knowledge regarding their responsibility for their pet. A questionnaire was applied to 134 aged people, members of non-governmental organizations in the city of Araçatuba, SP, in order to find out how they took care of their pet animals. The pets aged from 2 to 336 months, being 43,3% mixed-breed animals. Out of that, 60,9% were male dogs and among cats, 65.2% were female cats. There was a 69.4% preference for dogs and a 17.9% preference for cats, only 10.5% of the elderly had preference for birds. From the descriptive statistics analysis it could be observed that 69.40% did not have any access to the street and that 50% did not have a veterinarian follow-up. Regarding vaccination it could be observed that 71.64% had received the rabies vaccine and 70.9% had received the combination vaccine. Also, 74.63% did not know the right moment to give medicines against animal worms. Another important fact was that 85.07% of the animals were not castrated and 84.91% were not under any preventive contraception method. In regard to food 50.75% of the animals were fed strictly with animal food, 12.69% with domestic food and 36.57% with both. Finally, 78.36% of the pets had never been ill. In this way, we can assure the importance of making responsible pet ownership measures well-known among third-aged people.
