Alterações hematológicas em cães e gatos sob estresse

The leukocyte count interpretation on the blood helps on understanding about the possible dysfunction showed by the animal. In general, an abnormal leukogram allows the identification of pathological process. A lot of events lead to an increase in the number of neutrophils, among then, inflammatory process, infection and stress. Dependent on the stress mediator that the animal is submited, the leukocyte alteration will be different. Is important to know how the stress acts on the animal organism, changing the hematological parameters, in order to avoid mistakes on diseases‟ diagnosis. It‟s known that after a stress situation, it‟s expected that stress leukogram appears on the hemogram of the animal. However there are different kinds of stress with different responses. It‟s believed that when the animal is under an acute stress situation, a clinical picture of physiologic leukocytosis occurs which is mediated by the epinephrine. This is characterized by neutrophilia, lymphocytosis, monocytosis and eosinofilia. The physiologic leukocytosis is a transient alteration in the leukogram that occurs within minutes of the stimulus and due to fleeting effect of catecolamines it resolves within 20 to 30 minutes. However, if the animal is under chronicle stress, as solitude, it „s expected to find the stress leukogram on the leukogram, that can be noted especially in dogs. The stress leukogram is characterized by leukocytosis, neutrophilia, lymphopenia, monocytosis and eosinopenia. This kind of stress is induced by the glucocorticoids. It´s important to understand that stress leukogram takes time to occur. The variation on time depends on the animal species, although, in general, the glucocorticoides have a peak effects among 4 to 8 hours, which can last from 24 hours to 2 or 3 days

Endoscopia do trato gastrointestinal de cães e gatos

Endoscopy of the gastrointestinal tract is a specialized minimally invasive diagnostic method and with both diagnostic and therapeutic possibilities. It is divided into two major groups, the rigid and flexible endoscopy. The first most widely used for visualization of body cavities that do not have a light, like the chest, for example, and the second for those with light as the gastrointestinal tract. In Brazil there are few professionals, veterinary hospitals or clinics that offer this type of service. Thus, endoscopy is an area of expertise of the veterinarian who is in huge expansion and has shown great applicability with excellent results in both clinical medicine and surgical small animals

Manejo da insuficiência renal aguda em cães e gatos

Acute renal failure (ARF) may be defined as a subtle loss of renal function, leading to accumulation of nitrogenated substances. Several causes may lead to the development of ARF in an animal, including severe shock, intense blood loss, hypotension, dehydration, hypovolemia, deep anesthesia and nephrotoxins. Fluid therapy remains the basis of ARF treatment in animals. Thee therapeutic objective is to normalize fluid balance, solve hemodynamic problems and promote urine production. The objective of the present study is to review the procedures to manage acute renal failure in dogs and cats.

Doença cerebelar em cães e gatos

Diseases of the cerebellar system are common in small animals, and result in a clinical syndrome characterized by hypermetria, base-wide stance and intentional tremors of the head and body. All movements of the limbs are spastic and awkward. The neurological examination assists in the localization of lesions restricted to the cerebellum or in the detection of disorders relating to other parts of the nervous system, which characterizes a multifocal disease process. Neurological disorders in dogs and cats may suggest a very extensive list of differential diagnoses, since they may be caused by infectious, degenerative and traumatic processes, among others. The possible etiologies for cerebellar syndrome include: aplasia and hypoplasia, abiotrophy, cancer, vascular stroke and inflammatory disorders. The aim of this paper is to review the clinical signs that aid in the location of the cerebellar lesion and discuss the possible causes of this syndrome in dogs and cats.

Lissencefalia em cães e gatos: revisão

Lissencephaly is a condition characterized by a lack of cerebral convolutions and sulci, which results from defective migration of nervous cells precursors in the telencephalus. The cause is presumably genetic. Lhasa-Apso dogs are most frequently affected, even though it may also occur in association with cerebellar hypoplasia in the Irish Setter, Wire-Haired Terrier and Samoieda breeds. This association was also reported in a cat. Clinical signs consist of dementia, aggressiveness, seizures, visual and olfactive dysfunctions, slow postural reactions and reduced menace response. Definitive diagnosis requires exams such as magnetic resonance imaging, cerebral biopsy or necropsy. There is no specific therapy for this disease, and seizures must be treated with anticonvulsants. The aim of this study is to review the literature regarding lissencephaly.

Avaliação ultrassonográfica abdominal modo-B em cães e gatos filhotes: revisão de literatura

In veterinary medicine, the same clinician usually follows an animal from birth to old age, whereas in human medicine different specialists are required. It is therefore essential that veterinarians know the normal imaging, biochemical, hematological and physical exam values for younglings, which differ significantly from those of adults of the same species. Abdominal radiographies of young animals are poorly defined due to differences in tissue constitution in relation to adults. These same factors, however, substantially improve sonographic images of the region. Nonetheless, the interpretation of B-mode sonographic findings in puppies is difficult due to the lack of information about the normal parameters in this phase of life. The objective of this study was to compile information about peculiarities of abdominal B-mode ultrasonography in puppies and kittens.

Avaliação da participação e confiabilidade da população em relação à campanha de vacinação anual contra a raiva de cães e gatos no município de Botucatu, São Paulo, Brasil

The annual vaccination campaign against rabies is the most effective prevention procedure for this disease in dogs and cats and hence for human protection also. However, in 2010 and 2011, this activity was interrupted in Brazil due to the occurrence of adverse events associated with vaccination. Even though cases of canine rabies have been decreasing in the last two decades, vigilance must be strengthened in order to maintain pet owners trust in the vaccines provided in public services. This study aimed to determine pet owners participation in the annual vaccination campaign carried out in Botucatu. During March and April 2012, the period before the 42nd campaign, 312 pet owners, dogs and cats, were interviewed. The homes were randomly drawn in blocks from different sectors of the city; all houses on the same block over the 120 km² of urban area participated in the sampling process. Statistical analysis was performed descriptively. The results showed that the owners main motivation to vaccinate their pets during the campaigns is rabies prevention (36%), followed by the proximity of the vaccination station to the house (20.7%), zero cost (10.9%), and the combination of all three factors (16.1%). When asked if they would take their animals back to be vaccinated in another campaign, 60.1% answered yes, 13.5% would go to a private clinic, 2.2% would not take because they do not trust the vaccine and 1.6% had not decided yet. We conclude that the respondents have realized how dangerous Rabies is, because even after the break period, they still utilized the vaccination campaign demonstrating confidence in its effectiveness, while knowing the campaign goals facilitates understanding and participation.

Alimentos tóxicos para cães e gatos

Pet animals are closer to their owners and for this reason erroneously share the same alimentation. Several substances can cause intoxication or poisoning in dogs and cats, being many of those also found in human food. Some foods that are edible for humans or even to other animal species can be risky for dogs and cats due to different metabolic pathways, and further damage can be caused depending on the amount or concentration consumed. Poisoning in animals occur intentionally or accidentally in the household of its owner, occurring acute onset of clinical signs. Thus, the objective of this review was to present the food products for humans that cannot be given to dogs and cats as well as clinical signs characteristic of a toxicosis, also demonstrating the therapy for the damage created by consumption of those substances. This review explores the mechanisms of action and clinical signs of toxicosis caused by chocolate, xylitol, macadamia nuts, onions, garlic, grapes and raisins, avocado, alcoholic beverages and milk.
