Carcinoma de células escamosas em epitélio nasal de um hamster chinês: relato de caso

The squamous cell carcinoma (SCC) is a neoplasm that affect pets, production animals and exotic animals, and it’s very common in tropical countries like Brazil, once it develops a sparsely pigmented, stratified squamous epithelium and on surfaces mucosa exposed to ultraviolet action. The SCC is quite infiltrative but rarely causes metastases. Its occurrence in the nasal epithelium is widely reported in cats. This case is a chinese hamster (Cricetulus griséus), female, young, who developed a nasal nodule, and their only clinical sign was intense itching. The animal underwent surgery to perform an incisional biopsy, which was referred to the Veterinary Pathology Service of UNESP, campus of Araçatuba (SP) for histopathological evaluation. The material showed features consistent with squamous cell carcinoma well differentiated.

Histomorfometria do útero de gatas submetidas à ovariosalpingohisterectomia

Histomorphometric data were obtained from cats uterine horns: either nulliparous (n = 6), primiparous (n = 6), multiparous (n = 6) and treated with contraceptive (n = 6). The material was collected after surgery, fixed in paraformaldehyde and embedded in paraplast® resin to be sliced in a microtome. The obtained sections were stained with hematoxylin - eosin and measured under a light microscope: uterine wall total thickness (μm), endometrium total height, endometrial glands diameter and glandular epithelia height, total myometrium, internal and external myometrium and vascular layer thickness. It was concluded that: 1 - contraceptive use and number of pregnancies altered the uterine structure, 2 - one pregnancy does not appear to affect the uterine lining structures as occurs in multiparous cats, 3 – there was no variation on the evaluated structures between nulliparous and primiparous cats except for inner myometrium, 4 - the total myometrium hight and the endometrium hight showed similar variations except for the contraceptive treated cats group, 5 - the outer myometrium showed marked changes in the treated cats, 6 – the less marked morphological variations were for the endometrial glands diameter and glandular epithelium hight, 7 - the presence of dilated endometrial glands was found only in treated cats.

Leishmaniose visceral no Brasil

Visceral leishmaniasis (VL) is among the most important vector-borne diseases that occur in Brazil, mainly due to its zoonotic nature. It is currently present in almost all Brazilian territory, and its control is a challenge both for veterinarians and for public health officials. The etiologic agent is Leishmania infantum (syn chagasi), and the main vector in Brazil is Lutzomyia longipalpis. Of all animals identified as reservoirs of VL, the dog is considered the most important domestic reservoir. Although the disease has already been identified in cats, the epidemiological role of this animal species is still unclear. This article presents a brief review of the epidemiological situation of the disease, its mode of transmission, clinical features in dogs and cats as well as possible risk factors associated with the occurrence of the disease in Brazil.

Autismo: aspectos cognitivos, educacionais e neurobiológicos com base na análise dos livros Mundo singular: entenda o autismo e o Os gatos nunca mentem sobre o amor e na literatura especializada

The autism is a severe mental illness that involves psychological, social, educational and neurobiological aspects. The Education plays an important role in recovering, preserving and increasing the cognitive task of people with autism. There are several ways to observe a person with autism. Through the studying of cases, it is also possible to address issues of everyday life of the person with the illness, its cognitive issues and its obstacles of psychosocial involvement, as well as psychological aspects such as illness acknowledgement. Through specialized literature, it is possible to identify characteristics referring to the learning process and neurobiological components involved in the condition, such as brain activity disorder and genetic factors. The objectives of this paper are: from the analysis of two books: Unique World: comprehend the Autism (SILVA, A. B. B; GAIATO, M.B; REVELES, L.T) and The cats never lie about love (DILLON, J.), it is intended to describe cognitive and psychosocial aspects of the autism. Based on the specialized literature, the goal is to identify cognitive and neurobiological components in the illness. The methods that were used: analysis of the books Unique World: comprehend the Autism and The cats never lie about love to describe psychosocial and educational aspects of the autism; analysis of the specialized literature to identify clinical and neurobiological components of the illness, such as changes in brain activity, genetic factors or clinical evolution; and also details of the Education role in preserving the person with autism and his cognitive and emotional development. The study had the documentary research as reference for the methodological design, including book analysis and research in specialized literature. It is intended to deepen discussions about the Education roles related to the cognitive and neurobiological aspects of the autism

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.

Meningite supurativa secundária a otite média e interna em um gato: relato de caso

Suppurative meningitis are rarely reported in dogs and cats. The present study aims to report the occurrence of suppurative meningitis secondary to otitis media and interna in a five-year-old female Persian cat examined at the Veterinary School of Unesp-Botucatu with acute progressive multifocal neurological alterations. Analysis of the cerebrospinal fluid (CSF) demonstrated predominance of neutrophils (90%) and the presence of bacteria. Therapy with antibiotics was initiated, but the animal came to die. beta-hemolytic Staphylococcus, beta-hemolytic Streptococcus and Proteus mirabilis were detected in fragments sent to culture. The present report demonstrates the importance of performing more specific exams such as complete CSF analysis in cases of otitis media and interna. This way, central nervous infections can be diagnosed and treated in a timely manner, as those are acute diseases with poor prognosis.

Glioma misto em um cão: relato de caso

Intracranial neoplasms are common causes of neurological disorders in middle-aged and elderly dogs. With the feasibility of computed tomography, it is now possible to determine the extent and exact location of brain tumors, identifying them ante mortem in dogs and cats. This paper aims to report the occurrence of a mixed glioma in a Boxer dog examined at the Veterinary Hospital of Unesp, Botucatu Campus. The animal presented with a brain syndrome of acute onset and progressive course. CT scan showed the presence of a mass in the right cerebral hemisphere extending from the frontal to the parietal region and involving the basal ganglia. Given the gravity of the neurological disorder, the owner chose to perform euthanasia. Microscopic analysis of the mass allowed the diagnosis of mixed glioma.

Ritmo sinoventricular secundário a hipercalemia em gatos com obstrução uretral: breve descrição de três casos

Hyperkalemia is a common electrolyte imbalance in cats with obstructive feline lower urinary tract disease (FLUTD). The effects of serum potassium elevation in heart rhythm are serious and potentially lethal. The clinical manifestations reflect changes in the excitability of the cell membrane. Increased potassium levels lead to a reduction of the resting membrane potential of heart muscle cells, making them less excitable and resulting in cardiac arrhythmias. The sinoventricular rhythm with atrial arrest is among the types of arrhythmias caused by hyperkalemia. The purpose of this report was to highlight the importance of electrocardiographic monitoring for the early detection of potentially lethal arrhythmias in cats with obstructive FLUTD. We hereby describe the occurrence of three cases treated at the Small Animal Clinic of FMVZ/Unesp, Botucatu Campus.

Contato com gatos: um fator de risco para a toxoplasmose congênita?

Toxoplasmosis is an important zoonosis and one of the most common parasitic infections throughout the world, which may cause among other problems several fetal pathologic alterations. Congenital toxoplasmosis is a result of transplacental transmission of Toxoplasma gondii due to a prime infection of the mother during pregnancy. Several studies have determined that the main risk factor for infection in pregnant women is the consumption of uncooked meat, which contributed from 30 to 63% of cases; other 6% to 17% of infections were related to contaminated soil. The relationship between pregnant women and their cats constitutes nothing more than a healthy experience when main transmission mechanisms and risk factors related to the disease are known.

Avaliação de sobrevida, alterações genitourinárias, comportamentais e de peso corpóreo no pós-operatório tardio em cadelas e gatas submetidas à ovariosalpingohisterectomia sob diferentes métodos de ligadura do pedículo ovariano

A contracepção cirúrgica é utilizada no controle populacional, por impedir definitivamente a reprodução e ser mais econômica em relação à eutanásia. As complicações ocorrem pela intervenção cirúrgica ou por efeitos sistêmicos da privação do estrógeno. Objetivou-se monitorar o período pós-operatório de cadelas e gatas castradas em projeto de extensão universitária, com o intuito de avaliar os benefícios e a incidência de efeitos adversos. Foram questionados por telefone os proprietários de 178 fêmeas castradas (135 caninas e 43 felinas), entre um e dois anos após a cirurgia. As questões envolviam o estado atual do animal, possível mortalidade, neste caso a causa da morte e quanto tempo após a cirurgia ocorreu, se ocorreram alterações físicas como ganho de peso, incontinência urinária e dermatite peri-vulvar e alterações comportamentais positivas, como docilidade e diminuição do comportamento de perambulação, ou negativas, como apatia, agressividade e agitação excessiva. Das 135 cadelas castradas, 12 (8,89%) apresentaram óbito, apenas um relacionado à cirurgia, 87 (64,44%) apresentaram ganho de peso após a cirurgia, uma (0,74%) apresentou incontinência urinária e quatro (2,96%) dermatite peri-vulvar. Alterações de comportamento positivas foram relatadas em 38 (28,15%) cadelas e negativas em seis (4,44%). Das 43 gatas castradas, seis (13,95%) apresentaram óbito, nenhum relacionado à cirurgia, 25 (58,14%) apresentaram ganho de peso, uma (2,32%) incontinência urinária e duas (4,65%) dermatite peri-vulvar . Alterações de comportamento positivas ocorreram em 20 fêmeas (46,51%) e alterações negativas em nenhuma fêmea (0%). Pode-se concluir que a contracepção cirúrgica apresenta boa relação custo-benefício no que diz respeito a alterações pós-operatórias de longo prazo.
