Use of Phototherapy and Er-YAG Laser in the Management of Mandible Osteoradionecrosis: A Case Report.

Introduction: Osteoradionecrosis (ORN) is a secondary complication from radiotherapy, which is difficult to manage and significantly reduces the life quality of the affected patients. Case Report: A 59-year-old female patient, diagnosed with infiltration by squamous cell carcinoma in the left cervical region, underwent adjuvant cervical-facial radiotherapy with a total dose of 66.6 Gy of radiation. Eight years after the diagnosis, the patient underwent multiple extractions and, subsequently, the installation of osseointegrated implants, evolving to extensive intraoral bone exposure associated with oral cutaneous fistula. The patient was initially exposed to photobiomodulation therapy (PBMT), with a low-power laser at wavelengths of 660 nm and 808 nm, and thereafter to antimicrobial photodynamic therapy (aPDT). After an improvement in the clinical condition and resolution of the oral cutaneous fistula, a surgical procedure with the Er: YAG laser was performed to remove the remaining necrotic bone. Once the ORN condition was completely treated, the patient's oral rehabilitation was implemented by the installation of an upper mucous-supported total prosthesis and a lower implant-supported prosthesis. Conclusion: The patient is in a clinical follow-up and has no signs of bone necrosis recurrence, suggesting that low and high-power laser treatment can be an effective therapeutic alternative to resolve this condition.

Application of vascular photobiomodulation therapy in individuals with low back pain and its relationship with global methylation / Aplicação da terapia por fotobiomodulação vascular em indivíduos com lombalgia e sua relação com a metilação global

ABSTRACT BACKGROUND AND OBJECTIVES: Low back pain is among the most disabling conditions worldwide, and among the epigenetic factors, methylation in CpG islands of gene promoter regions can modulate gene expression, potentially correlating with the development of the disease and providing insights into the choice of treatment. The objective of this study was to assess the efficacy of therapy using modified ILIB related to DNA methylation processes in low back pain. Secondary objectives of this study included investigating pain intensity, gender, sociodemographic data, and physical-functional profile. METHODS: This prospective study was conducted in a municipality in the southern region of Brazil. The sample consisted of 30 participants of both genders, with an average age of 41.77 years. The following aspects were analyzed: anthropometric characteristics, global methylation using the ELISA method, pain level, physical activity level, functional disabilities, and hesitancy level related to work and physical activity-related activities. RESULTS: A statistically significant association was observed between methylation levels before and after treatment application for the experimental and placebo groups (p < 0.005), demonstrating a mean responsiveness between methylation and treatment (d = 0.5). However, there were no other statistically significant associations correlated with the other work variables. CONCLUSION: The results obtained in this study suggest the need for further research related to the identification of specific genes in methylation, as well as the standardization of dosimetry used for transcutaneous ILIB laser application in the radial artery.

RESUMO JUSTIFICATIVA E OBJETIVOS: A lombalgia está entre as condições mais incapacitantes no mundo e; dentre os fatores epigenéticos, a metilação em ilhas CpG de regiões promotoras de genes pode modular a expressão gênica permitindo uma possível correlação ao desenvolvimento da doença, como também pode trazer esclarecimentos a respeito do tratamento a ser escolhido. O objetivo deste estudo foi verificar a eficácia da terapia através do uso do ILIB modificado relacionada ao processo de metilação de DNA na lombalgia. Os objetivos secundários deste estudo foram a investigação da intensidade da dor, sexo, dados sociodemográficos e perfil físico-funcional. MÉTODOS: Este estudo, desenvolvido em um município da região sul do Brasil, caracteriza-se como prospectivo. A amostra deste estudo foi composta por 30 participantes, de ambos os sexos, com idade média de 41,77 anos. Foram analisados os seguintes aspectos: características antropométricas, metilação global através do método ELISA, nível de dor, nível de atividade física, incapacidades funcionais e nível de hesitação para realizar atividades relacionada ao trabalho e atividade física. RESULTADOS: Observou-se associação estatisticamente significativa entre os níveis de metilação antes e a após aplicação do tratamento para grupo experimental e placebo (p<0,005) demostrando uma média responsividade entre as variáveis metilação e tratamento (d=0,5). No entanto, não houve nenhuma outra associação estatística correlacionada as demais variáreis do trabalho. CONCLUSÃO: Os resultados obtidos neste estudo sugerem que há necessidade mais estudos relacionados a identificação de genes específicos na metilação, além da necessidade de padronização de dosimetria utilizadas para aplicação do laser ILIB de forma transcutânea, em artéria radial.

Effects of photobiomodulation with blue Light Emitting Diode (LED) on the healing of skin burns.

The management of skin burns is still challenging. Among the therapeutic methods used, there are topical treatments with pharmacological and herbal agents, low-intensity therapeutic ultrasound, use of biomaterials, reconstructive techniques and photobiomodulation therapy. The aim of this study was to evaluate the effects of photobiomodulation with blue Light Emitting Diode (LED) on burn healing. Fifty Wistar rats were divided into control (CTRL) (n = 25) and blue LED (LED) (n = 25), with subgroups (n = 5) for each time of euthanasia (7, 14, 21, 28 and 32 days). Treated animals were daily irradiated (470 nm, 1W, 0.44 W/cm2, 50 J/cm2). Clinical evaluations were performed and the Wound Retraction Index (WRI) was determined. Histological sections were submitted to hematoxylin-eosin, toluidine blue and the immunohistochemical technique, with anti-α-SMA and anti-TGF-ß1 antibodies. All data were directly collected by previously calibrated evaluators in a blind manner. The values were included in a statistical program. For all statistical tests used, 5% significance level (p < 0.05) was considered. No statistically significant differences in WRI between groups were observed (p > 0.05). Re-epithelialization was higher using LED at 7 and 14 days (p < 0.05) and greater amount of inflammatory cells was observed at 7 days (p = 0.01). With LED at 21 and 32 days, greater number of mast cells were observed (p < 0.05), as well as smaller number of myofibroblasts at 14, 21, 28 and 32 days (p < 0.05) and lower percentage of TGF-ß1 positive cells in the conjunctiva at 7, 14 and 21 days (p < 0.05). Negative correlations were observed in LED between the percentage of TGF-ß1 in the epithelium and the mean number of inflammatory cells and number of myofibroblasts (p < 0.05). The results suggest that, depending on the period, blue LED can modulate the healing processes of third-degree skin burns, such as re-epithelialization, inflammatory response, mast cell concentration, myofibroblast differentiation and TGF-ß1 immunoexpression. Despite these effects, this therapy does not seem to have significant influence on the retraction of these wounds. Future studies, using different protocols, should be carried out to expand the knowledge about the photobiomodulatory mechanisms of this type of light in the healing process.

Efeitos clínicos da fotobiomodulação como terapia adjuvante não-cirúrgica na periodontite crônica: uma revisão integrativa da literatura / Clinical effects of photobiomodulation as non-surgical adjuvant therapy for chronic periodontitis: an integrative literature review

Introdução: A doença periodontal, de origem infecciosa, constitui diferentes quadros clínicos de caráter multifatorial e inflamatório. A fotobiomodulação é uma técnica não invasiva que tem demonstrado ser capaz de diminuir a inflamação e proporcionar alívio da dor. Estudos também demonstraram que a adoção da fotobiomodulação adjuvante à raspagem e alisamento radicular tem sido capaz de reduzir a carga bacteriana proveniente da periodontite crônica. Objetivos: Analisar os efeitos da fotobiomodulação como terapia adjuvante à raspagem e ao alisamento radicular no tratamento da periodontite crônica publicados nos últimos cinco anos. Métodos: Trata-se de uma revisão integrativa da literatura, realizada no período de setembro a novembro de 2021, mediante a utilização dos seguintes descritores: "Periodontitis", "Photobiomodulation" e "Therapy, selecionando artigos publicados em inglês durante o período entre 2016 a 2021. Resultados: Foram identificados 47 trabalhos. Destes, foram excluídos 39 estudos que se dispersaram do tema e 2 que se encontravam indisponíveis para o acesso, resultando em 6 artigos que foram consultados integralmente. Foi consenso entre os artigos consultados que a prática da fotobiomodulação tornou-se um potencial agente terapêutico no tratamento da periodontite crônica contribuindo para a redução da contagem de periodontopatógenos e que atua de maneira coadjuvante às raspagens radiculares. Conclusão: A fotobiomodulação mostrou-se uma ferramenta promissora na área odontológica. Entretanto, a grande variedade nos parâmetros de tratamentos e protocolos utilizados na fotobiomodulação impossibilita uma comparação e uma análise mais crítica e rigorosa dos resultados obtidos nos trabalhos analisados.

Introduction: Periodontal disease, which has an infectious origin, constitutes a multifactorial and inflammatory different clinical condition of multifactorial, inflammatory, and infectious origin. Photobiomodulation is a non-invasive technique that has been shown to decrease inflammation and provide pain relief. Studies also have shown that the choosing of photobiomodulation as adjuvant therapy to scaling and root planing has been able to reduce the bacterial load from chronic periodontitis. Objectives: To analyze the effects of photobiomodulation as an adjuvant therapy to scaling and root planing in the treatment of chronic periodontitis in the studies published in the last five years. Methods: This is an integrative literature review, carried out from September to November 2021, using the following descriptors: "Periodontitis", "Photobiomodulation" and "Therapy, from selected articles published in English during the period between 2016 to 2021. Results: From the research and selection of studies to compose this integrative literature review, 47 studies were initially identified based on the descriptors. From those, 39 papers that were outside from the topic and 2 papers that were unavailable for access were excluded from the present review. Then remained, 6 articles that were fully consulted. The practice of photobiomodulation has become a potential therapeutic agent in the treatment of chronic periodontitis reducing the count of periodontopathogens and as an adjunct therapy to root scaling. Conclusion: Photobiomodulation therapy has become a promising tool in the dental field, however, the great variety in the treatment parameters and protocols used for photobiomodulation makes impossible to compare and perform a more critical and rigorous analysis of the results collected in the present work.

Effects of Photobiomodulation on High-Intensity Intermittent Anaerobic Performance of Lower Limbs in Brazilian Jiu-Jitsu Athletes: A Randomized, Crossover, Double-Blind Clinical Trial.

Photobiomodulation (PBM) has ergogenic effects on aerobic and anaerobic efforts and may improve sports performance. As Brazilian jiu-jitsu (BJJ) fighting requires both aerobic and anaerobic metabolism, so PBM may be effective in increasing the physical performance of BJJ athletes. Thus, this study aimed to verify the effects of PBM with different energy doses (6 or 12 J per point) on high-intensity intermittent anaerobic performance in BJJ athletes. METHODS: Eleven male athletes performed three lower limb Wingate testing sessions. At the beginning of each session, in a randomized, crossover, double-blind fashion, the athletes received PBM with a dose of 6 J (4.5 J/cm2) or 12 J (9.1 J/cm2), or placebo (PLA) at 17 points in each lower limb. In each session, the squat jump (SJ) and three Wingate test series were performed, with a 3-minute interval between series. Heart rate (HR) was collected immediately before, after each Wingate test, and at 1, 3, and 5 minutes after the last test. The rate of perceived exertion (RPE) was reported after each Wingate test. Differences between Wingate tests and treatment sessions were set at p<0.05. RESULTS: No differences were observed between treatments in SJ height, Wingate performance, HR, and RPE (p>0.05; for all comparisons). The Wingate test session promoted a reduction in anaerobic capacity in the second and third sets in all conditions, indicating fatigue (p<0.05). CONCLUSION: Treatment with PBM did not produce a dose-dependent ergogenic response in high-intensity intermittent performance in BJJ athletes.

Objetivo: Estudo quase experimental aprovado pelo Comitê de Ética em Pesquisas com Seres Humanos ­ COPEP da Universidade Estadual de Maringá, sob Parecer nº. 5.262.784, cujo objetivo foi avaliar a segurança e eficácia da laseracupuntura como uma abordagem terapêutica complementar no tratamento da fadiga e capacidade pulmonar em pacientes pós-COVID. Materiais e método: Nos meses de fevereiro e maço de 2023, no ambulatório de enfermagem da Universidade Estadual do Paraná, Campus de Paranavaí, foram recrutados 23 pacientes da comunidade acadêmica (discentes, docentes e agentes universitários) da própria universidade, com idade mediana de 24 anos (IQR = 22,0, 32,0), com diagnóstico prévio de COVID-19 e que apresentavam sintomas de fadiga e queixa de desconforto respiratório por pelo menos quatro semanas após a recuperação da fase aguda da doença. Dados demográficos, socioeconômicos e de estado de saúde geral e relacionados à COVID-19 foram coletados. Os pacientes foram tratados com duas sessões semanais de laseracupuntura por um período de cinco semanas. Para identificação da presença e intensidade da fadiga, foi aplicada a Escala de Fadiga de Piper Revisada com 23 itens e dividida em três dimensões, no início e final do tratamento e realizados testes de função pulmonar por espirometria para descrição do padrão ventilatório dos voluntários, em todas as sessões. Resultados: Participaram 23 voluntários com idade mediana de 24 anos (IQR, 22-32) e predominantemente do sexo feminino (N= 15 [65%]) e da cor branca (N = 13 [56,4%]). A maioria dos voluntários tinha sobrepeso ou obesidade (N = 16 [79,6%]). Após a fase aguda da COVID-19, os sintomas mais relatados foram ansiedade (65%), queda de cabelo (35%) e dor de cabeça (30%). Todos os participantes apresentaram fadiga intensa pós-COVID (6,36 [IQR = 6,00 ­ 7,73]). Os resultados do estudo mostraram que o tratamento com a laseracupuntura resultou em redução significativa nas pontuações da escala de fadiga quanto à Dimensão comportamental (Diferença média [DM] = -1,65; IC 95%; 0,56-2,75; p < 0,001) Dimensão afetiva (DM = -2,43; IC 95%; 1,33-3,52; p < 0,001) e Dimensão sensorial (DM= -2,85; IC 95%; 2,08-3,63; p < 0,001), além do total geral de fadiga (-2,44; IC 95%; 1,63-3,24; p < 0,001), mas não apresentou qualquer efeito nas medidas de função pulmonar como Capacidade Vital Forçada (DM = -0,87; IC 95%; -4,24, 5,98); p = 0,727), manobra básica avaliada em espirometria e relação entre Volume expiratório forçado em 1 segundo (VEF1) e Capacidade vital forçada (CVF), o VEF1/CVF (DM = -1,00; IC 95%; -10,38-8,39; p = 0,828). Nenhum efeito colateral foi relatado durante o tratamento. Conclusão: O protocolo de laseracupuntura foi seguro e bem tolerado pelos pacientes, sem efeitos colaterais relatados durante o tratamento, sugerindo que a laseracupuntura pode ser uma opção segura para o tratamento da fadiga pós-COVID-19. Apesar da intervenção não ter provocado efeito nos padrões respiratórios dos voluntários, estes verbalizaram melhora da expansibilidade e dor torácica, aumento do fôlego e disposição. Sugere-se novos estudos controlados para melhor compreensão do manejo dos sintomas pós-agudos da COVID-19.

Objective: Quasi-experimental study approved by the Ethics Committee for Research with Human Beings ­ COPEP of the State University of Maringá, Opinion nº. 5,262,784, whose objective was to evaluate the safety and efficacy of laser acupuncture as a complementary therapeutic approach in the treatment of fatigue and lung capacity in post-COVID patients. Materials and method: In February and March 2023, at the nursing clinic of the State University of Paraná, Campus Paranavaí, 23 patients were recruited from the academic community (students, professors and university agents) of the university itself, with a median age of 24 years old (IQR = 22.0, 32.0), with a previous diagnosis of COVID-19 and who had symptoms of fatigue and a complaint of respiratory distress for at least four weeks after recovery from the acute phase of the disease. Demographic, socioeconomic, and general health and COVID-19 related data were collected. The patients were treated with two laseracupuncture sessions per week for a period of five weeks. To identify the presence and intensity of fatigue, the Revised Piper Fatigue Scale was applied, with 23 items and divided into three dimensions, at the beginning and end of treatment, and pulmonary function tests were performed by spirometry to describe the ventilatory pattern of the volunteers, in all sessions. Results: Participants were 23 volunteers with a median age of 24 years (IQR, 22-32) and predominantly female (N = 15 [65%]) and Caucasian (N = 13 [56.4%]). Most volunteers were overweight or obese (N = 16 [79.6%]). After the acute phase of COVID-19, the most reported symptoms were anxiety (65%), hair loss (35%) and headache (30%). All participants experienced severe post-COVID fatigue (6.36 [IQR = 6.00 ­ 7.73]). The results of the study showed that treatment with laser acupuncture resulted in a significant reduction in scores on the fatigue scale for the Behavioral Dimension (Mean difference [MD] = -1.65; CI 95%; 0.56-2.75; p < 0.001) Affective dimension (DM = -2.43; CI 95%; 1.33-3.52; p < 0.001) and Sensory dimension (DM = -2.85; CI 95%; 2.08-3, 63; p <0.001), in addition to the fatigue grand total (-2.44; 95% CI; 1.63-3.24; p < 0.001), but had no effect on measures of lung function such as Forced Vital Capacity (MD = -0.87; 95% CI; -4.24, 5.98); p = 0.727), basic maneuver evaluated in spirometry and ratio between Forced Expiratory Volume in 1 Second (FEV1) and Forced Vital Capacity (FVC), FEV1/FVC (DM = -1.00; CI 95%; -10.38 -8.39; p = 0.828). No side effects were reported during treatment. Conclusion: The laseracupuncture protocol was safe and well tolerated by patients, with no reported side effects during treatment, suggesting that laseracupuncture may be a safe option for treating post-COVID-19 fatigue. Although the intervention had no effect on the breathing patterns of the volunteers, they reported improvement in chest expansion and pain, increased breath and disposition. New controlled studies are suggested to better understand the management of post-acute symptoms of COVID-19.

Se han recopilado datos demográficos, socioeconómicos y de salud general relacionados con el programa COVID-19. Los pacientes fueron tratados con dos sesiones de laseracupuntura por semana durante cinco semanas. Para la identificación de la presencia y la intensidad de la fatiga, se revisó la escala de fatiga de los piper con 23 elementos y se dividió en tres dimensiones, al inicio y al final del tratamiento, y se realizaron pruebas de función pulmonar mediante espirometría para describir el patrón de ventilación de los voluntarios, en todas las sesiones. Resultados: participaron 23 voluntarios con una edad media de 24 años (RCI, 22-32) y predominantemente mujeres (N = 15 [65%]) y blancas (N = 13 [56,4%]). La mayoría de los voluntarios presentaron sobrepeso u obesidad (N = 16 [79,6%]). Después de la fase aguda de COVID-19, los síntomas notificados más frecuentemente fueron ansiedad (65%), pérdida de pelo (35%) y dolor de cabeza (30%). Todos los participantes presentaron fatiga grave post-COVID (6,36 [IQR = 6,00 - 7,73]). Los resultados del estudio mostraron que el tratamiento con laseracupuntura dio lugar a una reducción significativa de las puntuaciones de la escala de fatiga para la dimensión conductual (Diferencia media [DM] = -1,65; IC del 95%; IC del 0,56-2,75; p < 0,001) La dimensión afectiva (DM = -2,43; IC del 95%: 1; 33-3,52; p < 0,001) y dimensión sensorial (DM = -2,85; IC del 95% 2,08-3,63; p < 0,001), además de la fatiga general (-2,44; IC del 95%: 1,63-3,24; p < 0,0 01), pero no tuvo efecto sobre las medidas de función pulmonar como capacidad vital forzada (DM = -0,87; IC del 95%; -4,24,5,98); p = 0,727), maniobra basal evaluada en espirometría y relación entre el volumen respiratorio forzado 1 segundo (VEF1) y la capacidad viciosa forzada (CVF), EF1/CVF (DM = -1,00; IC del 95%; -10,38-8,39; p = 0,828). No se notificaron efectos adversos durante el tratamiento. Conclusión: El protocolo de laseracupuntura fue seguro y bien tolerado por los pacientes, sin efectos secundarios notificados durante el tratamiento, lo que sugiere que la laseracupuntura puede ser una opción segura para el tratamiento de la fatiga post-COVID-19. Aunque la intervención no tuvo efecto sobre los patrones respiratorios de los voluntarios, verbalizaron mejoría en la capacidad de expansión y dolor torácico, dificultad respiratoria y disposición. Se sugieren nuevos estudios controlados para entender mejor el manejo de los síntomas post-agudos de COVID-19.

A pandemia da COVID-19, provocou um grande impacto na saúde mental das pessoas, mesmo após a fase aguda da doença, resultando em altas taxas de ansiedade e depressão, tornando necessário o desenvolvimento e a avaliação de tratamentos, não farmacológicos, eficazes para aliviar esses sintomas. Este estudo quase-experimental, aberto, unicêntrico, realizado nos meses de fevereiro e março de 2023, no ambulatório de enfermagem da Universidade Estadual do Paraná, campus de Paranavaí, teve como objetivo avaliar a eficácia da Laseracupuntura, para o tratamento de ansiedade e depressão, na Síndrome Pós-COVID-19. O estudo foi aprovado pelo Comitê de Ética (Parecer nº. 5.262.784). Foram coletados dados demográficos, socioeconômicos e de estado de saúde. A presença e a intensidade de ansiedade e depressão foram verificadas no início e, ao final, do tratamento, por meio do Inventário de Ansiedade de Beck (21 itens) e Inventário de Depressão de Beck (21 itens). Ao todo, 23 voluntários receberam até 10 sessões, de um protocolo de Laseracupuntura, para tratar ansiedade e depressão pós-COVID-19. Os pontos P1, PC6, E36, E25, VC6, VC12, VC17 e Yintang, foram estimulados por luz de laser infravermelho sobre a pele. Os participantes eram predominantemente, mulheres, de raça/cor branca e tinham sobrepeso ou obesidade. Os sintomas pós-agudos da COVID-19, mais relatados, foram: ansiedade, queda de cabelo e dor de cabeça. A mediana inicial de pontuação das escalas de ansiedade e depressão foram de 23,00 (IQR, 13,50 ­ 27,50) e 22,00 (IQR, 11,50 ­ 26,50), respectivamente. A intervenção resultou em reduções significativas, nas pontuações de duas escalas: de ansiedade (DM = -9,74; IC 95%, 4,88 ­ 14,60; p < 0,001) e depressão (DM = -9,87; IC 95%; 5,53 ­ 14,21; p < 0,001). Nenhum efeito colateral foi relatado durante o tratamento. Os resultados obtidos neste estudo, sugerem que, a Laseracupuntura pode ser uma terapia eficaz e segura para tratar sintomas de ansiedade e depressão em pacientes pós-COVID-19. Além disso, o uso da laseracupuntura, tem a vantagem adicional de ser menos invasiva que a Acupuntura tradicional, tornando-a uma opção atraente para pessoas que buscam tratamentos integrativos para saúde mental, sem os riscos presentes em terapias medicamentosas tradicionais. Recomenda-se a realização de mais estudos ­ principalmente ensaios clínicos randomizados ­, para confirmar a eficácia da Laseracupuntura.

The COVID-19 pandemic has had a major impact on people's mental health even after the acute phase of the disease, resulting in high rates of anxiety and depression, making it necessary to develop and evaluate treatments, non- pharmacological, effective to alleviate these symptoms. This quasi-experimental, open- label, unicentric study, conducted in February and March 2023, at the nursing outpatient clinic at Paraná State University, Paranavaí campus, aimed to evaluate the effectiveness of Laseracupuncture, for the treatment of anxiety and depression, in Post-COVID-19 Syndrome. The study was approved by the Ethics Committee (Opinion No. 5 262 784). Demographic, socioeconomic and health status data were collected. The presence and intensity of anxiety and depression were verified at the beginning and at the end of the treatment, through the Beck Anxiety Inventory (21 items) and Beck Depression Inventory (21 items). In all, 23 volunteers received up to 10 sessions of a Laseracupuncture protocol to treat post-COVID-19 anxiety and depression. The points P1, PC6, E36, E25, VC6, VC12, VC17 and Yintang, were stimulated by infrared laser light on the skin. Participants were predominantly women of white race/color and were overweight or obese. The most reported post-acute symptoms of COVID-19 were: anxiety, hair loss, and headache. The median baseline scores for the anxiety and depression scales were 23.00 (IQR, 13.50 - 27.50) and 22.00 (IQR, 11.50 - 26.50), respectively. The intervention resulted in significant reductions in the scores of two scales: anxiety (DM = -9.74; 95% CI, 4.88 - 14.60; p < 0.001) and depression (DM = -9.87; 95% CI; 5.53 - 14.21; p < 0.001). No side effects were reported during treatment. Results obtained in this study suggest that Laseracupuncture may be an effective and safe therapy for treating symptoms of anxiety and depression in post-COVID-19 patients. In addition, the use of laseracupuncture has the additional advantage of being less invasive than traditional Acupuncture, making it an attractive option for people seeking integrative treatments for mental health, without the risks present in traditional drug therapies. Further studies - mainly randomized clinical trials - are recommended to confirm the efficacy of Laseracupuncture.

Los participantes fueron predominantemente mujeres blancas/de raza y tenían sobrepeso u obesidad. Los síntomas post-agudos más frecuentemente notificados de COVID-19 fueron ansiedad, pérdida de pelo y dolor de cabeza. La mediana inicial de la puntuación de ansiedad y depresión osciló entre 23,00 (RPI, 13,50 - 27,50) y 22,00 (RI, 11,50 - 26,50), respectivamente. La intervención dio lugar a reducciones significativas en las puntuaciones de dos escalas: ansiedad (DM = -9,74; IC del 95%, 4,88 - 14,60; p < 0,001) y depresión (DM = -9,87; IC del 95%; IC del 5,53 al 14,21; p < 0,00 1. No se notificaron efectos adversos durante el tratamiento. Los resultados de este estudio sugieren que Laseracupuntura puede ser una terapia eficaz y segura para tratar los síntomas de ansiedad y depresión en pacientes post- COVID-19. Además, el uso de laseracupuntura tiene la ventaja adicional de ser menos invasiva que la acupuntura tradicional, lo que la convierte en una opción atractiva para las personas que buscan tratamiento integrador para la salud mental, sin los riesgos presentes en los medicamentos tradicionales. Se recomiendan otros estudios, principalmente ensayos clínicos aleatorizados, para confirmar la eficacia de Laseracupuntura.

Desafios terapêuticos da mucosite oral em oncopediatria / Therapeutic challenges of oral mucositis in pediatric oncology

O Neuroblastoma (NB) é uma neoplasia do sistema nervoso simpático, e o segundo tumor sólido maligno extracraniano mais comum da infância. Na terapia antineoplásica, complicações orais podem ser observadas, dentre elas a mucosite oral (MO). Trata-se de uma inflamação aguda da mucosa, proveniente da toxicidade dos quimioterápicos. Este relato de caso enfatiza o manejo da MO, bem como sua influência na condição sistêmica e qualidade de vida. Paciente do sexo feminino, nove anos, apresentou recidiva de NB metastático, após tratamento de primeira linha. Admitida na unidade hospitalar para tratamento oncológico na enfermaria de pediatria oncológica, queixando-se de dor intensa em cavidade bucal e orofaringe, associada a pancitopenia severa febril. Ao exame físico apresentava disfagia e déficit ponderal grave, que debilitava a deglutição da própria saliva. O exame intraoral revelou lesões de MO grau 3, segundo a Organização Mundial de Saúde (OMS), em lábios, gengiva anterior e orofaringe. O tratamento consistiu em remoção de debris local, higiene da cavidade bucal com clorexidina 0,12% e utilizando haste flexível de algodão estéril tipo "Swab", visando controle microbiano local, diariamente. Além disso, foi aplicado no leito eritematoso e hemorrágico fotobiomodulação (660 nm, 50 mW, 2 J/cm2, 90 segundos) pontualmente nas áreas do leito da lesão e em varredura na região de orofaringe (sessões intercaladas). Foi prescrito acetato de racealfatocoferol (vitamina E) para ação antioxidante e hidratação dos lábios. Concomitante a mucosite, a paciente apresentou pancitopenia febril severa, sendo necessário uso de cefepima 150 mg/kg/dia, com coleta prévia de hemoculturas, fator estimulador de colônias de granulócitos, Fluconazol, hidratação e suporte nutricional. As hemoculturas foram negativas. As consequências da mucosite contribuíram para desnutrição e piora da qualidade de vida. Conclui-se que a intervenção odontológica em interdisciplinaridade, possibilitou o restabelecimento físico e emocional, possibilitando melhor uma qualidade de vida da paciente (AU).

Neuroblastoma (NB) is a neoplasia of the sympathetic nervous system and the second most common extracranial malignant solid tumor in childhood. In antineoplastic therapy, oral complications can be observed in antineoplastic therapy, among them oral mucositis (OM). It is an acute mucosa inflammation resulting from the toxicity of chemotherapy drugs. This case report emphasizes the management of OM and its influence on the systemic condition and quality of life. A female patient, nine years old, presented a recurrence of metastatic NB after first-line treatment. She was admitted to the hospital unit for oncological therapy in the pediatric oncology ward, complaining of severe pain in the oral cavity and oropharynx associated with severe febrile pancytopenia. On physical examination, she presented dysphagia and severe weight deficit, which weakened the swallowing of her saliva. According to the World Health Organization (WHO), the intraoral exam revealed third-grade OM lesions on the lips, anterior gum, and oropharynx. Treatment consisted of removing local debris, cleaning the oral cavity with 0.12% chlorhexidine, and using a flexible, sterile cotton swab, aiming for daily local microbial control. In addition, photobiomodulation (660 nm, 50 mW, 2 J/cm2, 90 seconds) was applied to the erythematous and hemorrhagic bed, punctually in the areas of the lesion and sweeps in the oropharynx region (interspersed sessions). Racealphatocopherol acetate (vitamin E) was prescribed for antioxidant action and lip hydration. Concomitant with mucositis, the patient had severe febrile pancytopenia, requiring cefepime 150 mg/kg/day, with previous collection of blood cultures, granulocyte colony-stimulating factor, fluconazole, hydration, and nutritional support. Blood cultures were negative. The consequences of mucositis contributed to malnutrition and worsened quality of life. It is concluded that the interdisciplinary dental intervention enabled physical and emotional restoration, enabling a better quality of life for the patient (AU).

Photobiomodulation therapy prevents dysgeusia chemotherapy induced in breast cancer women treated with doxorubicin plus cyclophosphamide: a triple-blinded, randomized, placebo-controlled clinical trial.

PURPOSE: To evaluate the effectiveness of photobiomodulation (PBMT) in preventing dysgeusia in breast cancer patients treated with doxorubicin-cyclophosphamide (AC). METHODS: This is a phase II, randomized, triple-blind, placebo-controlled clinical trial involving 112 breast cancer patients treated with AC. The patients were divided equally into two groups: a test group treated with 2 J red laser and 3 J infrared laser on 21 points that were symmetrically distributed on the tongue on day 0 of four cycles of AC, and an equal placebo group treated with simulated PBMT to blind the patient, evaluator, and statistician. The clinicopathological and sociodemographic data, results of taste test, and subjective taste analysis, and the QoL, ECOG performance status, body mass index, and other side effects were recorded. The data were analyzed using ANOVA-RM/Bonferroni, Friedman/Dunn, and chi-square/Fisher's exact tests. RESULTS: PBMT patients showed less objective and subjective taste loss (p<0.05). On the other hand, the placebo group showed a higher ECOG status (p=0.037) and more significant weight loss (p<0.001) after four cycles of AC. The QoL was significantly higher in the PBMT group (p<0.05) at all assessment periods, and PBMT treatment also reduced the incidence of cachexia (p=0.020), anorexia (p<0.001), diarrhea (p=0.040), oral mucositis (p=0.020), and vomiting (p=0.008). CONCLUSION: PBMT reduced the taste loss and improved the overall health status and QoL of patients with breast cancer treated with AC.

Clinical Evaluation of Intravascular Blood Irradiation with Laser, Photobiomodulation, and Photodynamic Therapy in Cancer Patients with Mucositis.

Objective: To assess the clinical application of intravascular laser irradiation of blood (ILIB), photodynamic therapy (PDT), and photobiomodulation therapy (PBM-T) in mucositis in cancer patients. Background: PBM-T and PDT are used for the management of oral mucositis (OM) and there are no studies associating intravascular laser irradiation of blood (ILIB) for this purpose. Materials and methods: Thirty-six patients were allocated by convenience into three groups according to the established therapy: PDT+PBM-T (n = 10); PDT+PBM-T+ILIB (n = 10), and ILIB (n = 16). PDT was performed with the photosensitizer curcumin and irradiation of the oral cavity with blue light-emitting diode (LED) (power 1200 mW and wavelength 468 nm). PBM-T was performed using low-intensity laser (power 100 mW, wavelength 660 nm, and spot energy 1 J) at 26 points of the oral cavity. ILIB was applied with a bracelet on the radial artery using the low-intensity laser (100 mW of power, 660 nm wavelength, and 30 J of total energy). All therapies were performed weekly for 5 weeks. The results of the OM degrees were analyzed using the Wilcoxon test. Results: There was a significant reduction in the degrees of OM after treatment with PDT+PBM-T (p = 0.0117), PDT+PBM-T+ILIB (p = 0.0277), and ILIB (p = 0.0277). Conclusions: It was concluded that ILIB, PDT, and PBM-T reduced the severity of mucositis and prevented its onset. Clinical Trial Registration number: RBR-54XS25.

Photobiomodulation of red and green lights in the repair process of third-degree skin burns.

The aim of this study was to evaluate the photobiomodulation of red and green lights in the repair process of third-degree skin burns in rats through clinicopathological and immunohistochemical parameters. Sixty male Wistar rats were divided into three groups: control (CTRL) (n = 20), red LED (RED) (n = 20), and green LED (GREEN) (n = 20), with subgroups (n = 5) for each time of euthanasia (7, 14, 21, and 28 days). Daily applications in RED (λ630 ± 10 nm, 300 mW) and GREEN groups (λ520 ± 30 nm, 180 mW) were performed at four points of the wound (total 36 J/cm2 in RED and 240 J/cm2 in GREEN). After euthanasia, the wound retraction index (WRI) was evaluated. In histological sections, the re-epithelialization degree, the angiogenic index (AI), and the amount of myofibroblasts in wounds were analyzed. At 14 and 21 days, the RED group induced higher re-epithelialization and WRI compared to CTRL (p > 0.05) and GREEN groups (p < 0.05). At 7 and 14 days, greater AI were observed in the GREEN group, with significant difference in relation to CTRL group at 7 days (p < 0.05). At 21 and 28 days, a trend was observed for greater amount of myofibroblasts in the GREEN group, with significant difference in relation to CTRL group at 21 days (p < 0.05). The results suggest greater potential of the green light to stimulate angiogenesis in the initial periods and myofibroblastic differentiation in the final periods of the repair of third-degree skin burns. Red light may stimulate further re-epithelialization and wound retraction, especially in advanced repair phases.

Avaliação do processo de reparo alveolar em ratos utilizando ß- tricálcio-fosfato associado ou não ao laser de baixa potência / Evaluation of the alveolar repair process in rats using ß-Tricalcium Phosphate associated or not with low power laser

O uso de biomateriais em substituição ao enxerto autógeno tem sido objeto de estudo, e apresentando resultados promissores. Deste modo, o objetivo desse estudo foi verificar os efeitos do ß-tricálcio-fosfato e do LASER de baixa potência no processo de reparo alveolar. Foram utilizados 96 ratos (Rattus novergicus albinus Wistar), sendo 24 ratos para análise dos cortes calcificados e 72 ratos para análise dos cortes descalcificados. Os animais foram submetidos a exodontia do incisivo superior direito e em seguida foi feita a separação por grupo e por tempo. Para os cortes calcificados, foi feita a divisão em 4 grupos de 6 animais cada: Grupo CO (Controle), Grupo BTF (Biomaterial), Grupo LS (LASER de baixa potência), Grupo BTFL (biomaterial LASER de baixa potência), eutanasiados no período de 28 dias. Para análise dos cortes descalcificados foram utilizados os mesmos grupos em tempos de eutanasia de 7,14 e 28 dias. As maxilas foram removidas e submetidas às análises histológica e histométrica nos cortes descalcificados e análise tomográfica microcomputadorizada (Micro-Ct) nos cortes calcificados. A análise por micro-Ct evidenciou formação de tecido ósseo em todos os grupos, porém não houve diferença entre os grupos experimentais e o controle. A análise histométrica evidenciou maior presença de tecido ósseo neoformado estatististicamente significante em LS aos 7 dias quando comparados aos demais grupos. Desta forma, concluiu-se que o LASER de baixa potência acelerou as fases inicias do processo de reparo alveolar(AU)

The use of biomaterials to replace autogenous grafts has been the subject of study, and has shown promising results. Thus, the objective of this study was to verify the effects of ß-tricalcium-phosphate and low-power LASER on the alveolar repair process. 96 rats (Rattus novergicus albinus Wistar) were used, being 24 rats for analysis of calcified cuts and 72 rats for analysis of decalcified cuts. The animals underwent extraction of the upper right incisor and then the separation was made by group and by time. For the calcified cuts, the division was made into 4 groups of 6 animals each: Group CO (Control), Group BTF (Biomaterial), Group LS (low power LASER), Group BTFL (low power LASER biomaterial), euthanized in the 28-day period. For the analysis of decalcified cuts, the same groups were used at times of euthanasia of 7.14 and 28 days. The jaws were removed and subjected to histological and histometric analysis in the decalcified sections and microcomputerized tomographic analysis (Micro-Ct) in the calcified sections. Micro-Ct analysis showed bone tissue formation in all groups, but there was no difference between experimental and control groups. Histometric analysis showed a greater presence of statistically significant neoformed bone tissue in LS at 7 days when compared to the other groups. Thus, it was concluded that the low-power LASER accelerated the early stages of the alveolar repair process(AU)

Effect of blue LED on the healing process of third-degree skin burns: clinical and histological evaluation.

The aim of this study was to evaluate the effects of blue light-emitting diode (LED) on the healing process of third-degree skin burns in rats through clinical and histological parameters. Forty male Wistar rats were divided into two groups: control (CTR) (n = 20) and blue LED (BLUE) (n = 20), with subgroups (n = 5) for each time of euthanasia (7, 14, 21, and 28 days). LED (470 nm, 1 W, 12.5 J/cm2 per point, 28 s) was applied at four points of the wound (total, 50 J/cm2). Feed intake was measured every other day. It was observed that there were no statistically significant differences in the Wound Retention Index (WRI) of the BLUE group in relation to CTR group (p > 0.05) at the evaluation times. After 14, 21, and 28 days, it was observed that the animals in the BLUE group consumed more feed than animals in the CTR group (p < 0.05). At 7 days, there was a statistically significant increase in the angiogenic index (AI) in BLUE (median: 6.2) when compared to CTR (median: 2.4) (p = 0.01) and all animals in BLUE had already started re-epithelialization. This study suggests that blue LED, at the dosimetry used, positively contributed in important and initial stages of the healing process of third-degree skin burns.

Efeito a curto prazo da laser acupuntura na dor, ansiedade e depressão de pacientes com disfunção temporomandibular: ensaio clínico randomizado / Short-term effect of laser acupuncture on pain, anxiety and depression in patients with temporomandibular disorders: randomized clinical trial

Objetivo: Avaliar o efeito a curto prazo da laser acupuntura na dor, ansiedade e depressão em pacientes com DTM. Métodos: Foi realizado um ensaio clínico randomizado cego com portadores de DTM, diagnosticados pelo Critério de Diagnóstico de DTM (RDC/TMD). 60 pacientes foram alocados de forma aleatória em quatro grupos distintos: aconselhamento (AC), placa Oclusal (PO), fisioterapia (FP) e laser acupuntura (LA) e foram avaliados no baseline, e com 1 mês após a terapia. Para avaliação da ansiedade foram utilizados HADS, BAI, e o IDATE. Para a depressão foi BDI e HADS. Para dor foi utilizada a EVA. Foi utilizado o teste Kruskal-Wallis com nível de confiança de 95% para análise entre grupos. O pós teste de Mann-Whitney, para verificar onde estava a diferença encontrada entre os grupos. E o teste de classificações assinadas por Wilcoxon, para análise entre os tempos analisados. Resultados: Ao longo do tempo houve redução na sintomatologia dolorosa nos grupos PL (p=0,001), FP (p= 0,014) e grupo LA ficou no limiar de significância (p= 0,08). Após 30 dias de terapia houve redução significativa entre os grupos FP versus AC (p=0,004) e FP versus LA (p=0,006). O grupo FP foi o único grupo que reduziu os sintomas de ansiedade pelo BAI (p=0,09) e pelo IDATE-E (p=0,042). Nos parâmetros depressivos houve diferença estatisticamente significativa ao longo do tempo pelo BDI nos grupos PO (p=0,044) e LA (p=0,009). Entre os grupos houve diferença estatisticamente significativa pelo BDI, entre PO versus LA (p=0,004), e FP versus LA (p=0,005). E pelo HADS, entre FP versus LA (p=0,012). Conclusão: Para pacientes com ansiedade e depressão, a laser acupuntura não é a terapia mais indicada para diminuição da sintomatologia dolorosa a curto prazo (AU).

Objective: To evaluate the short-term effect of laser acupuncture compared with counseling, occlusal plaque, and physiotherapy treatments on pain, anxiety, and depression in TMD patients. Methods: A randomized clinical trial was performed with patients with TMD, diagnosed by the TMD (RDC / TMD). 60 patients were randomly allocated to four distinct groups: counseling (AC), Occlusal Plaque (PO), physical therapy (PF) and laser acupuncture (LA) and were evaluated at baseline, and at 1 month after therapy. To evaluate anxiety, HADS, BAI, and STAI were used. For depression was BDI and HADS. For pain, VAS was used. The Kruskal-Wallis test with a 95% confidence level was used for intergroup analysis. The Mann-Whitney post-test, to verify where was the difference found between the groups. And the Wilcoxon signed rank test for analysis between the times analyzed. Results: Over time there was a reduction in pain symptoms in the PL (p = 0.001), PF (p = 0.014) and LA groups were at the significance threshold (p = 0.08). After 30 days of therapy there was a significant reduction between the PF versus AC (p = 0.004) and FP versus LA (p = 0.006) groups. The FP group was the only group that reduced anxiety symptoms by BAI (p = 0.09) and by STAI-E (p = 0.042). In depressive parameters there was a statistically significant difference over time by BDI in the PO (p = 0.044) and LA (p = 0.009) groups. Between groups there was a statistically significant difference by BDI, between PO versus LA (p = 0.004), and PF versus LA (p = 0.005). And by HADS, between FP versus LA (p = 0.012). Conclusion: For patients with anxiety and depression, laser acupuncture is not the most appropriate therapy to reduce pain symptoms in the short term (AU).
