Osteossarcoma em gatos : revisão de literatura

Neoplasias ósseas primárias costumam ser incomuns em gatos, sendo o Osteossarcoma (OSA) o tipo que mais acomete a espécie. O OSA é um tumor mesenquimal maligno, cuja as células produzem matriz óssea. Tem comportamento agressivo com crescimento rápido e alto potencial de realizar metástase, podendo acometer o esqueleto apendicular, tendo predileção por membros pélvicos como fêmur distal e tíbia proximal, e o esqueleto axial, afetando regiões como crânio e cavidade oral. É rara a ocorrência de OSA extraesquelético em gatos. O objetivo desse estudo é abordar os aspectos do OSA na espécie felina na clínica de pequenos animais, elucidando os sinais clínicos da doença, bem como os principais métodos de diagnóstico e de tratamento disponíveis.Primary bone neoplasms are often uncommon in cats, with Osteosarcoma (OSA) being the type that most affects the species. OSA is a malignant mesenchymal tumor, which cells produce bone matrix. It has an aggressive behavior with rapid growth and a high potential for metastasis. It can affect the appendicular skeleton and has a predilection for pelvic limbs such as the distal femur and proximal tibia, and the axial skeleton, affecting regions such as skull and oral cavity. The occurrence of extraskeletal OSA in cats is rare. The objective of this study is to highlight the relevance of OSA to the feline species in the small animal clinic, elucidating the clinical signs of the disease, as well as the main methods of diagnosis and treatment available

Use of thermography as an auxiliary method to diagnose orofacial pain: a case study

ABSTRACT Thermography is an auxiliary diagnostic method widely used to assess soft tissues and thus diagnose neuropathic or inflammatory pain. The objective of this paper was to report a case in which thermography was used as an auxiliary method to diagnose neuropathic pain. The patient in question is a 43-year-old woman with complaints of pain and sensitivity in the upper and lower left dental arches, particularly when consuming alcoholic beverages. The case was assessed with thermography, followed by the Cold Stress Test. The symmetry of the thermographic images and the localized changes helped rule out neuropathic problems and diagnose the orofacial inflammatory pain. The thermography was used as an auxiliary instrument to diagnose orofacial pain, proving to be efficient. Also, the thermography helped rule out changes originating in peripheral, small-fiber, and inflammatory neuropathies, aiding the patient’s differential diagnosis. The thermography also helped identify the thermo-anatomical points and, with the qualitative and quantitative analyses, noninvasively investigate the possible causes of the orofacial pain reported by the patient
