ABSTRACT
A dor neuropática é causada por uma lesão ou doença do sistema nervoso somatossensitivo. Trata-se de uma manifestação sindrômica que envolve mecanismos inflamatórios e imunes com fisiopatologia ainda pouco esclarecida. O espectro de apresentação da dor neuropática é amplo e, assim, constitui um desafio na prática clínica. Este problema de saúde pública necessita de ampla capacidade técnica dos clínicos generalistas. Torna-se relevante identificar o potencial de cronificação do sintoma e adotar abordagens mitigantes do processo lesivo, estrutural e emocional. Nesse sentido, o diagnóstico adequado da dor neuropática é o primeiro passo na abordagem ao paciente. Diante disso, essa revisão objetiva facilitar a melhor escolha dos métodos diagnósticos no manejo clínico do paciente. Dentre estes, é possível citar a imagem por ressonância magnética funcional, eletroneuromiografia, tomografia por emissão de pósitrons, microneurografia, teste quantitativo sensorial, biópsias de pele, estudos de condução nervosa e de potencial somatossensorial evocado. A dor, por ser um processo sensorial subjetivo, apresenta amplo espectro de manifestações clínicas. Por essa razão, é possível fazer uso de técnicas como métodos de triagem e exames complementares para um diagnóstico mais específico.
Neuropathic pain is caused by an injury or illness of the somatosensory nervous system. It is a syndromic manifestation that involves inflammatory and immune mechanisms, whose pathophysiology is still poorly understood. The spectrum of presentation of neuropathic pain is wide and, therefore, it is a challenge in clinical practice. This public health problem requires the broad technical capacity of general practitioners. It is relevant to identify the potential for chronicity of the symptom and adopt mitigating approaches to the harmful, structural, and emotional process. In this sense, the proper diagnosis of neuropathic pain is the first step in approaching the patient. Therefore, this review aims to facilitate the best choice of diagnostic methods in the clinical management of the patient. Among these, functional magnetic resonance imaging, electroneuromyography, positron emission tomography, microneurography, quantitative sensory testing, skin biopsies, nerve conduction and evoked somatosensory potential studies are possible. Pain, being a subjective sensory process, has a wide spectrum of clinical manifestations. For this reason, it is possible to make use of techniques such as screening methods and complementary exams for a more specific diagnosis.

SUMMARY OBJECTIVE: The aim of this study was to highlight the differences between the cardiometabolic effects and the cardiovascular risk of physical inactivity and sedentary behavior. METHODS: A narrative bibliographic review was conducted. In the research, national and international articles were selected from the PubMed, SciELO, and LILACS databases using the descriptors "sedentary lifestyle, cardiovascular risk, physical inactivity, sedentary behavior, and cardiovascular risks." DISCUSSION: Both physical inactivity and sedentary behavior are related to metabolic and organic changes, promoting a chronic proinflammatory state, cardiac remodeling, increased body adiposity, and skeletal muscle dysfunction. It is possibly stated that both of them result in a higher risk of developing chronic diseases, resulting in higher global and cardiovascular morbidity and mortality, with nuances in their intrinsic effects. CONCLUSIONS: It is inferred that both physical inactivity and sedentary behavior are cardiovascular risk factors that can be modified with the correct clinical approach. It is necessary to differentiate physically inactive individuals from those with a high number of sedentary behaviors. These concepts need better clinical applicability to improve the prevention of primary and secondary cardiovascular risks.
