Neuroblastoma olfatório em cão: achados tomográficos e histopatológicos

The occurrences of neoplasia’s in the nasal cavity in dogs occur in approximately 1% of all neoplasms. Olfactory neuroblastoma is a neuroepithelial neoplasm of the nasal cavity and paranasal sinuses rarely reported in dogs and has as main clinical signs epistaxis, sneezing, respiratory distress, facial deformity and neurological changes. For definitive diagnosis, histopathological examination is indispensable, and extensive mitosis, pleomorphism and necrosis are generally observed. There is still no standard protocol for the treatment of olfactory neuroblastoma, but removal of the tumor followed by radiotherapy is the treatment modality that has given the patients a longer survival time. The objective of this work was to report a case of olfactory neuroblastoma in a dog with no defined breed at eleven years old, highlighting the diagnostic methods for this disease, with emphasis on tomographic and histopathological findings.

Carcinoma de células escamosas em felino: relato de caso

Squamous cell carcinoma (SCC), also known as squamous cell carcinoma, squamous cell carcinoma or squamous cell carcinoma, is a cutaneous malignant neoplasm that appears frequently in felines, presenting in this species a distinct behavior of the other species. Prolonged exposure to ultraviolet (UV) light seems to be one of the etiologic factors of the disease, just as the hypopigmented and low-hair areas are the most affected. The color of the coat is one of the predisposing factors, it is known that white-coated cats are more likely to present the disease when compared to the pigmented ones. Regarding localization, most of the lesions are observed in the head and more often in the nasal plane, followed by the auricles and eyelids, and may present in varied forms as proliferative or erosive. The diagnostic suspicion comes through the history and clinical characteristics of the lesions, but for diagnostic definition cytological and histopathological examination is necessary. Precocity in diagnosis has a fundamental effect on prognosis. There are several treatment modalities for squamous cell carcinoma including surgery, ionizing radiation, chemotherapy, photodynamic therapy, electrochemotherapy and cryosurgery. Cryosurgery consists of the controlled use of low temperatures in order to induce cell death. The objective of this work was to report two cases of felines diagnosed with squamous cell carcinoma treated with different protocols. Animal 1 is a 10-year-old, male, 10-year-old male with ulcerative lesion in the nasal plane for approximately 6 months, attended at the Veterinary Clinic in Olinda-PE. The diagnosis was made through a cytological examination, identifying squamous cell carcinoma. The treatment established was cryosurgery, but the animal did not receive a favorable treatment response, probably due to the delay in the search for veterinary care, which delayed the diagnosis and consequently aggravated the neoplastic lesion making it difficult to treat. The animal was submitted to euthanasia after worsening of its clinical condition, 2 months after starting the treatment. Animal 2 is a 14-year-old undefined female feline with ulcerative lesion in the left ear. The diagnosis was made through cytology and histopathology. The established treatment was surgery. To date, the animal has not had any complications.

Comparação de alfa-2-adrenérgicos na anestesia epidural sacrococcigea de gatas submetidas à ovariosalpingohisterectomia

The research was carried out at the Veterinary Hospital, the Department of Veterinary Medicine of Rural Federal University of Pernambuco, where they were used 15 cats undergoing ovariosalpingohisterectomy, participated and aged between one and three years, with weight that ranged between three and four pounds, divided into three groups, submitted to ovariosalpingohisterectomy. The animals were pre-medicated with acepromazine 2%, 0.05 mg/kg. The Ketamine hydrochloride 50 mg/ml, 10 mg/kg and diazepam 5 mg/ml, 0.5 mg/kg, were used for anesthetic induction and maintenance was performed using the ketamine hydrochloride at a dose of 4 mg/kg. Then, they were subjected to epidural anesthesia the sacrococcygeal using only clonidine in dose of 20 μg/kg or xylazine at the dose 2 mg/kg or saline (placebo) 1 ml/3.5-kg. The animals were assessed in relation to hemodynamic parameters, respiratory and body temperature, in addition to the evaluation of the analgesic potential and intensity was reached from the measurement glucose, lactate and cortisol levels, since the pre-anesthetic until the end of the surgery.

Alterações microbianas dos produtos de pescados curados: Revisão

By definition, fish are aquatic organism used for human consumption, including all their parts and derivatives. Being a product subject to inadequate manipulation and easy deterioration, fish consumption may become a risk to public health, being a potential transmitter of pathogenic microorganisms to humans. So it is necessary to implement appropriate conservation techniques for this class of food. The cure process is used in order to increase the shelf-life and the added value of products, as well as influence their organoleptic characteristics.
