“…The most reliable laboratory tool for assessing nociceptive pathway function is laser-evoked potential (LEP) recording (Haanpää et al, 2011;Valeriani et al, 2012). LEPs are related to the activation of type II AMH mechanothermal nociceptors.…”

RESUMOObjetivos: Realizar uma revisão da literatura sobre o tratamento da neuralgia pós-herpética com irradiações a laser de baixa intensidade. Métodos: A revisão foi realizada nos meses de novembro a dezembro de 2015 nas bases de dados LILACS, SciELO e Medline, utilizando-se os descritores "herpes zoster", "neuralgia" e "terapia a laser de baixa intensidade" e seus correspondentes termos em inglês. Os critérios de inclusão foram artigos disponíveis na íntegra, publicados em português, inglês, alemão ou espanhol, no período compreendido entre 2008 a 2015. Os critérios de exclusão foram textos incompletos, artigos que não abordaram diretamente a temática do estudo e repetição de um mesmo artigo na mesma ou em diferentes bases de dados, nesse caso sendo considerado apenas um deles. Resultados: A partir dos descritores utilizados foram encontrados 32 estudos. Após aplicação dos critérios de elegibilidade foram selecionados 15 artigos para leitura, dos quais foram excluídos dois por repetição e um por não apresentar resultados relevantes a esta pesquisa. Dessa forma, 11 estudos foram incluídos na revisão, dos quais cinco foram realizados nos Estados Unidos, dois no Brasil, dois na Alemanha e dois na Itália, sendo quatro ensaios clínicos, duas revisões sistemáticas e cinco relatos de casos. Os 11 estudos encontraram resultados positivos após aplicação do laser, principalmente diminuição da dor, e apenas um artigo mencionou pouca redução da neuralgia. Nos três estudos que informaram os parâmetros de irradiação estes não foram uniformes, sendo a média do comprimento de onda 740,6 nm, a média da potência 28 mW e a média do tempo de irradiação por ponto 53,4 segundos. Quanto ao número de sessões, houve grande variação, com uma média de aproximadamente 12 sessões em dia alternados. Conclusões: A terapia com laser de baixa intensidade ofereceu resultados positivos aos pacientes com neuralgia pós-herpética, entretanto não há um consenso quanto aos parâmetros a serem utilizados. Em razão dos diferentes protocolos descritos, é importante realizar mais estudos que auxiliem a padronizar os parâmetros dessa terapia aplicados à neuralgia pós-herpética. DESCRITORES: herpes zoster; neuralgia; terapia a laser de baixa intensidade. ABSTRACT Aims:To perform a literature review on the treatment of postherpetic neuralgia with low-intensity laser irradiation. Methods: The review was conducted in November and December 2015 by searching the terms "herpes zoster", "neuralgia", "low-level laser therapy", and "low-intensity laser therapy" in the LILACS, SciELO, and Medline databases. Full articles published in Portuguese, English, German, or Spanish between 2008 and 2015 were included. Incomplete articles, those that did not directly address the topic of interest, and those appearing in the same or in different data...

“…Laser-evoked potentials can be induced with stimulation from solid-state (thulium or neodinium-based) or CO 2 lasers. Solid-state lasers use shorter wavelengths, which leads to a faster rise in temperature that means shorter pulses and higher amplitudes are needed, thereby shortening the latency of the cortical response and reducing the risk of superficial burns 180 . However, the shorter wavelength means the technique is more easily affected by skin pigmentation than use of CO 2 lasers, so that the delivery of energy to the skin is uneven.…”

New technologies for the assessment of neuropathies

et al. 2017

Peripheral neuropathies are among the most common neurological disorders 1 . In routine clinical practice, diagnosis of peripheral neuropathies is typically based on clinical assessment, nerve conduction studies and needle electromyography, which can determine whether symptoms are caused by primary axonal damage or demyelinating damage. This distinction is often relevant to therapeutic choices and to prognosis, as axonal damage typically reflects an inflammatory (for example, vasculitic) or degenerative (for example, hereditary or idiopathic) process that correlates with disability, whereas demyelinating damage can reflect a hereditary neuro pathy, but more often reflects an acquired immunemediated neuropathy. Besides metabolic, inflammatory or primary degenerative neuropathies, peripheral nerves can also be damaged by compression from adjacent tissue structures, such as tendons, cysts or haematomas. In this case, proper identification of the site, nature and degree of the lesion might be challenging, but is relevant to treatment and prognosis. Moreover, some patients present with symptoms that suggest damage to small nerve fibres, which nerve conduction studies cannot be used to detect.In the past 15 years, several techniques have become available to investigate focal and diffuse peripheral neuropathies, and their reliability has widened the spectrum of diagnostic tools for clinicians and improved assessment of neuropathies. In this Review, we provide an overview of these new and emerging technologies. We first discuss peripheral nerve imaging with MRI and ultrasonography, which can provide information about the precise localization of neuro pathies and the pathological processes involved in large-fibre neuropathies, and can complement clinical and electrophysiological evaluation. We then consider techniques that can provide diagnostic information when the pathological process is restricted to small nerve fibres and is consequently not detectable with nerve conduction studies or neuroimaging. These include skin biopsy, which is established in clinical practice, and the emerging techniques of corneal confocal microscopy, laser-evoked potentials and heat-related and pain-related evoked potentials, and microneurography.Nerve imaging technology Advances in imaging techniques have made it possible to gain great insight into nerve pathology with magnetic resonance and ultrasound. Each approach offers distinct advantages, and can provide different information about damage to large myelinated fibres. Abstract | Technical advances are rapidly changing the clinical and instrumental approach to peripheral nerve diseases. Magnetic resonance neurography, diffusion tensor imaging and nerve ultrasonography are increasingly entering the diagnostic workup of peripheral neuropathies as tools that complement neurophysiology and enable investigation of proximal structures, such as plexuses and roots. Progress in the design of magnetic resonance scanners and sequences, and the development of high-frequency ultrasound probes mean th...
