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.

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.

Cognitive dysfunction syndrome (CDS) is a progressive degenerative disorder of older dogs, characterized by a decline in cognitive function. The main clinical signs consistent with CDS are: disorientation, changes in socio-environmental interaction, sleep-wake cycle disturbance, changes in hygiene habits, urinate and/or defecate in unusual places, decreased physical activity, anxiety and eating disorders. There are no specific diagnostic tests for this condition in vivo, but alterations in neurological examination, cognitive tests and magnetic resonance imaging can be observed. The diagnosis is confirmed by histopathological examination of brain tissue. Diets rich in antioxidants, environmental enrichment with exercise and the use of selegiline and L-deprenyl have been recommended for the treatment of CDS.

Computed tomography (CT) can be considered an important test to identify the presence of primary brain neoplasias in dogs. CT results can help define the type of brain tumor when associated with clinical findings. It allows the identification of lesions and their features, such as size, location, compression and invasion of adjacent tissue. One must analyze the density, mass effect, peritumoral edema, calcification, and image enhancement after intravenous injection of contrast medium. Gliomas, meningiomas and tumors of the choroid plexus and pituitary are the most common primary brain neoplasms diagnosed by CT in dogs. The aim of this paper is to review the literature related to primary brain tumors and report their most important tomographic features, in order to help clinicians achieve a presumptive diagnosis of tumor type.

Desde os anos 1950, tem se constatado que, em alguma medida, os valores do terapeuta se fazem presentes na psicoterapia, podendo, inclusive, influenciar os valores dos clientes. Embora apresente uma concepção de valores diferente das tradicionais, a terapia analítico-comportamental não é uma exceção. Este trabalho busca esclarecer como os valores do terapeuta podem se manifestar na clínica analítico-comportamental, sejam esses valores pessoais ou compartilhados com alguma cultura (e.g., sociedade em geral, Psicologia, Análise do Comportamento). Para tanto, mostra-se como o conceito de valor tem sido abordado na Análise do Comportamento e o que possibilita a manifestação dos valores do terapeuta na clínica analítico-comportamental. Por fim, discutem-se brevemente algumas implicações do tema para a prática clínica.

Abstract Background Oral squamous cell carcinoma (OSCC) is a frequent neoplasm, which is usually aggressive and has unpredictable biological behavior and unfavorable prognosis. The comprehension of the molecular basis of this variability should lead to the development of targeted therapies as well as to improvements in specificity and sensitivity of diagnosis. Results Samples of primary OSCCs and their corresponding surgical margins were obtained from male patients during surgery and their gene expression profiles were screened using whole-genome microarray technology. Hierarchical clustering and Principal Components Analysis were used for data visualization and One-way Analysis of Variance was used to identify differentially expressed genes. Samples clustered mostly according to disease subsite, suggesting molecular heterogeneity within tumor stages. In order to corroborate our results, two publicly available datasets of microarray experiments were assessed. We found significant molecular differences between OSCC anatomic subsites concerning groups of genes presently or potentially important for drug development, including mRNA processing, cytoskeleton organization and biogenesis, metabolic process, cell cycle and apoptosis. Conclusion Our results corroborate literature data on molecular heterogeneity of OSCCs. Differences between disease subsites and among samples belonging to the same TNM class highlight the importance of gene expression-based classification and challenge the development of targeted therapies.

It has been evaluated clinically and radiographically the effect of the extrusion of calcium hydroxide paste in teeth with periapical lesions. Twenty-five patients with teeth showing pulp necrosis and periapical lesions were submitted to endodontic treatment. Dressing calcium hydroxide paste, iodoform and propylene glycol were used. Clinically, the symptoms were evaluated after treatment and, radiographically, the reabsorption of extravasated paste and repair process of the periapical lesion. Only three patients had symptoms severe in the first 24 hours, the paste was completely reabsorbed within 15 days and no interference in the repair process.

FUNDAMENTO: A realização da angiografia coronariana na insuficiência cardíaca sem etiologia definida é frequentemente justificada para avaliação diagnóstica de cardiopatia isquêmica. Porém, o benefício clínico dessa estratégia não é conhecido. OBJETIVO: Avaliar a prevalência de cardiopatia isquêmica mediante critérios angiográficos em pacientes com insuficiência cardíaca e fração de ejeção reduzida sem etiologia, assim como o seu impacto na decisão terapêutica. MÉTODOS: Foram avaliados pacientes ambulatoriais consecutivos com insuficiência cardíaca e disfunção sistólica, que tiveram a angiografia coronariana indicada para esclarecimento etiológico da cardiopatia, no período de 1º de janeiro de 2009 a 31 de dezembro de 2010. Os pacientes com diagnóstico de doença arterial coronariana, sorologia positiva para doença de Chagas, cardiopatia congênita, valvopatia grave ou pacientes submetidos a transplante cardíaco foram excluídos da análise. A amostra foi dividida em dois grupos conforme a indicação do cateterismo. Grupo-1: Sintomáticos em razão de angina ou insuficiência cardíaca refratária. Grupo-2: Presença de > 2 fatores de risco para doença arterial coronariana RESULTADOS: Cento e sete pacientes foram incluídos para análise, sendo 51 (47,7%) pacientes pertencentes ao Grupo-1 e 56 (52,3%), ao Grupo-2. A prevalência de cardiopatia isquêmica foi de 9,3% (10 pacientes), e todos pertenciam ao Grupo-1 (p = 0,0001). Durante o seguimento, apenas 4 (3,7%) tiveram indicação de revascularização miocárdica; 3 (2,8%) pacientes apresentaram complicações relacionadas ao procedimento. CONCLUSÃO: Em nosso trabalho, a realização da angiografia coronariana em pacientes com insuficiência cardíaca e disfunção sistólica sem etiologia, apesar de embasada pelas atuais diretrizes, não evidenciou benefício quando indicada apenas pela presença de fatores de risco para doença arterial coronariana.
