Síndrome de la arteria mesentérica superior (Síndrome de Wilkie): A propósito de un caso en una adolescente / Superior mesenteric artery syndrome (Wilkie syndrome): A case report in an adolescent

Introducción. El síndrome de la arteria mesentérica superior, también conocido como síndrome de Wilkie, es una entidad infrecuente en la que una reducción del ángulo o espacio aorto-mesentérico determina una compresión extrínseca con obstrucción del tercio distal del duodeno, demostrando síntomas y signos característicos de obstrucción intestinal. El pilar del tratamiento es el manejo médico conservador con repleción nutricional, con el objetivo de aumentar el grosor de la grasa retroperitoneal y con esto resolver la compresión duodenal. Caso clínico. Paciente de 16 años, con un curso crónico marcado por dolor abdominal, estreñimiento, distensión, pirosis y pérdida de peso. Inicialmente se trató como una enfermedad ácido-péptica, con pobre mejoría, por lo que se realizaron estudios imagenológicos con lo que se documentó una disminución del ángulo aortomesentérico. Resultado. Se instauró un manejo médico con un protocolo de repleción nutricional por vía oral, para lograr ganancia de peso y evitar la cirugía. Conclusión. Con base a los síntomas y hallazgos en imágenes diagnósticas se hizo el diagnóstico de síndrome de la arteria mesentérica superior, que es una causa de obstrucción intestinal con muy baja incidencia. Su presentación clínica incluye gran variedad de síntomas, entre los que destaca el dolor abdominal y la pérdida de peso. Es frecuente la confusión con otras enfermedades más frecuentes, como enfermedad ácido-péptica, reflujo gastrointestinal y malabsorción. Su diagnóstico requiere un alto índice de sospecha, por lo que es importante conocer esta entidad y considerarla en el estudio de pacientes con los síntomas mencionados.

Introduction. Superior mesenteric artery syndrome, also known as Wilkie syndrome, is a rare entity in which a reduction in the aorto-mesenteric angle or space determines extrinsic compression with obstruction of the distal third of the duodenum, demonstrating characteristic symptoms and signs of intestinal obstruction. The mainstay of treatment is conservative medical management with nutritional repletion, with the aim of increasing the thickness of the retroperitoneal fat and thereby resolving duodenal compression. Clinical case. A 16-year-old patient, with a chronic course marked by abdominal pain, constipation, bloating, heartburn and weight loss. Initially was treated as an acid-peptic disease, with poor improvement. Imaging studies were performed, which documented a decrease in the aorto-mesenteric angle. Conclusion. Based on the symptoms and findings on diagnostic images, the diagnosis of superior mesenteric artery syndrome was made, which is a cause of intestinal obstruction with a very low incidence. Its clinical presentation includes a wide variety of symptoms, among which abdominal pain and weight loss stand out. Confusion with other more common diseases is common, such as acid-peptic disease, gastrointestinal reflux and malabsorption. Its diagnosis requires a high index of suspicion, so it is important to know this entity and consider it in the study of patients with the aforementioned symptoms.

ABSTRACT Objective: To describe the chronology, evolution and impact of global research into chronic postoperative pain. Materials and methods: A bibliometric study was conducted using the Scopus database. A structured search was designed and validated, thereby allowing the collection of metadata, which were analyzed through the Bibliometrix package of the R programming language. The study involved the description of the general characteristics, evolution and calculation of impact metrics of global research into chronic postoperative pain. Results: The study included 1,496 documents, which spanned from 1983 to 2023. Original articles accounted for 70.7 % (n =1,059) of the total output, followed by reviews (n = 357; 23.8 %). There was an international collaboration rate of 15.6 %, and there has been sustained growth in output since 1983, with a sharp increase in the last 13 years, 2022 being the most prolific one (n =191 published documents). It was identified that Canada and Denmark lead the impact of global research and have the most productive authors and institutions. However, the United States is the most prolific country because it leads significant collaboration, mainly with European and Latin American countries. Neuropathic pain, risk factor assessment and pain management were identified as some of the most frequent topics. Over the past approximately 10 years, there has been persistent interest in research on quality of life, prediction, prevention, and risk factor assessment. Recently, there has been interest in studying pain in video-assisted thoracoscopic surgery and developing predictive models. Conclusions: The study revealed sustained growth in global research on chronic postoperative pain over the past 40 years. Such growth has been mainly led by Canadian and Danish institutions, despite the United States being the most prolific country. Moreover, there has been a significant transition in the studied topics, moving from the use of drugs and identification of risk factors to the study of predictive models, data systematization, and video-assisted surgery.

Chronic Pain and Erectile Dysfunction: Mechanism, Treatment, and Future Perspective

@#Erectile dysfunction is a problem with multiple causes and is challenging to diagnose. Chronic pain has been associated with erectile dysfunction in some studies. Chronic pain can be a potential direct or indirect cause of sexual dysfunction. A decreased sexual desire due to restricted sexual activity in chronic pain can result in erectile dysfunction. Erectile dysfunction has been linked to migraines, chronic pain, and psychological factors. Multiple neurotransmitters may contribute to the pathophysiology of erectile dysfunction. Depression and anxiety, as well as painkillers like pregabalin and opioids, can be indirect causes of erectile dysfunction. Numerous factors affect the occurrence of erectile dysfunction; therefore, erectile dysfunction must be treated holistically.

Chronic pain among older adults and its impact on satisfaction with social participation: development and validation of the "Instrument to Assess Older Adults' Social Participation". A descriptive quantitative study

ABSTRACT BACKGROUND: We aimed to develop and validate a practical instrument to assess older adults' satisfaction with their social participation (SP). DESIGN AND SETTING: This methodological validation study was conducted at a public higher education institution. METHODS: A two-phase study was designed, developed, and validated to assess older adults' satisfaction with their SP. In the first phase, we conceptualized SP and developed an "instrument to assess older adults' satisfaction with their SP (IAPSI)," as approved by a committee of specialists, pre-tested, and partially validated. Second, we determined the IAPSI's reproducibility using Cronbach's alpha to measure internal consistency, Pearson's and Spearman's coefficients to measure correlations, the Bland-Altman plot and intraclass correlation coefficient (ICC) to measure reproducibility. We also generated a receiver operating characteristic (ROC) curve. RESULTS: 102 older adults (mean age, 87.29) participated in the first phase. Moderate internal consistency (Cronbach's alpha 0.7) and significant moderate correlations with quality of life by World Health Organization Quality of Life (WHOQOL)-bref and by WHOQOL-old social domains (Pearson's coefficients 0.54 and 0.64, respectively; P < 0.001) were found. The ROC curve indicated an IAPSI score of 17 as the threshold for the impact of pain on satisfaction with SP (83.3% sensitivity and 88.9% specificity, P < 0.001). In the second phase, 56 older adults (between 81 and 90 years old) participated. We found adequate intra- and inter-observer reproducibility for the IAPSI (ICC 0.96 and 0.78, respectively). CONCLUSION: We have developed a practical instrument with appropriate psychometric properties to assess older adults' satisfaction with their SP.

Influence of the COVID-19 pandemic on sleep quality, psychosocial aspects, and physical activity levels in patients with chronic pain in Brazil: COVIDor cross-sectional study / Influência da pandemia de COVID-19 na qualidade do sono, em aspectos psicoemocionais e no nível de atividade física de pacientes com dor crônica no Brasil: estudo observacional COVIDor

ABSTRACT BACKGROUND AND OBJECTIVES: The social distancing of COVID-19 pandemic exacerbated symptoms of chronic pain patients. Furthermore, it is necessary to consider the sociocultural context of coping with the pandemic in different countries. The objective of this study was to evaluate pain, psychoemotional symptoms, sleep quality, and level of physical activity in chronic pain patients during the COVID-19 pandemic in Brazil. METHODS: Individuals with fibromyalgia, migraine and chronic low back pain were included. The survey was performed through a questionnaire elaborated by researchers on the Forms application, from Google Drive, in the period between October 2020 and March 2021, with straight and clear questions about pain, psychoemotional aspects, sleep quality, and level of physical activity. Binary or multinominal logistic regression analysis was performed to identify possible predictors. RESULTS: 973 people were evaluated, 63.5% had fibromyalgia, and 98.3% were female. Anxiety increased the odds ratio in 395% of chronic pain patients to feel pain (ß: 1.375; OR: 3.956; p=0.001) and a greater intensity of pain increases in 62.3% the chance of these individuals not performing physical activity (ß: -0.474; OR: 0.623; p=0.001). Pain intensity increased the odds ratio of having insomnia by 186.9% (ß: 0.625; OR: 1.869; p=0.001) and the chance of taking sleep drugs by 160.4% (ß: 0.472; OR: 1.604; p=0.001). CONCLUSION: The social isolation of COVID-19 pandemic maximized the vicious cycle between painful symptoms, anxiety, and sleep disorders in chronic pain patients in Brazil. The intensification of these factors is associated with the reduction of physical activity levels.

A intensidade da dor aumentou a razão de chances de ter insônia em 186,9% (ß: 0,625; OR: 1,869; p= 0,001) e a chance de tomar fármacos para dormir em 160,4% (ß: 0,472; OR: 1,604; p=0,001). CONCLUSÃO: O isolamento social da pandemia de COVID-19 maximizou o ciclo vicioso entre sintomas dolorosos, ansiedade e distúrbios do sono em pacientes com dor crônica no Brasil. A intensificação desses fatores está associada à redução de atividade física.

Prevalence and impact of comorbidities in women with chronic pelvic pain / Prevalência e impacto de comorbidades em mulheres com dor pélvica crônica

ABSTRACT BACKGROUND AND OBJECTIVES: Chronic pelvic pain (CPP) is a common condition in women and there are often associated comorbidities. The objective of this study was to evaluate the prevalence of comorbidities in patients with CPP and to seek associations between comorbidities and the manifestations of chronic pain. METHODS: Observational case-control study with sociodemographic, behavioral and clinical information, including comorbidities, in 246 women, 123 with CPP and 123 without CPP (control group). RESULTS: Anxiety, depression, migraine and endometriosis were the most frequent comorbidities in women with CPP. The comorbidities assessed in the CPP group were not associated with pain intensity score, history of abortion, physical violence or sexual violence (p>0.05). In the group of women with CPP and endometriosis, the median anxiety and depression score was significantly lower than in the group without endometriosis (14.5; 95% CI: 11.0-14.9) versus (17.0; 95% CI: 14.6-16.7), p=0.012 and (13.0; 95%CI: 11.1-15.9) versus (16.5; 95% CI: 14.5-17.6), p= 0.045, respectively. In patients with migraine, the median depression score was higher in the group of women with CPP compared to the group without CPP (15.0; 95% CI: 14.1-17.8) versus (10.0; 95% CI: 8.5-12.4), p=0.048. CONCLUSION: The most prevalent comorbidities in women with CPP were mental disorders, migraine and endometriosis. Comorbidities were not related to pain intensity, physical violence or sexual violence. Having a diagnosis of endometriosis is associated with lower anxiety and depression scores in patients with CPP. Overlapping migraine and CPP were associated with a worse depression score.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor pélvica crônica (DPC) é uma condição comum em mulheres e frequentemente há comorbidades associadas. O objetivo deste estudo foi avaliar a prevalência de comorbidades em pacientes de DPC e buscar associações entre comorbidades e as manifestações da dor crônica. MÉTODOS: Estudo observacional de caso-controle com informações sociodemográficas, comportamentais e clínicas, incluindo comorbidades, em 246 mulheres, sendo 123 com DPC e 123 sem DPC (grupo controle). RESULTADOS: Ansiedade, depressão, enxaqueca e endometriose foram as comorbidades mais frequentes em mulheres com DPC. As comorbidades avaliadas no grupo com DPC não se associaram com o escore de intensidade da dor, com história de aborto, de violência física nem de violência sexual (p>0,05). No grupo de mulheres com DPC e endometriose, a mediana do escore de ansiedade e de depressão foi significativamente menor do que no grupo sem endometriose (14,5; IC 95%: 11,0-14,9) versus (17,0; IC 95%: 14,6-16,7), p=0,012 e (13,0; IC 95%: 11,1-15,9) versus (16,5; IC 95%: 14,5-17,6), p=0,045, respectivamente. Em pacientes com enxaqueca, a mediana do escore de depressão foi maior no grupo de mulheres com DPC em relação ao grupo sem DPC (15,0; IC 95%: 14,1-17,8) versus (10,0; IC 95%: 8,5-12,4), p=0,048. CONCLUSÃO: As comorbidades mais prevalentes em mulheres com DPC foram transtornos mentais, enxaqueca e endometriose. As comorbidades não se associaram à intensidade da dor, violência física ou sexual. O diagnóstico de endometriose associou-se a menores escores de ansiedade e de depressão em mulheres com DPC. A sobreposição de enxaqueca e DPC associou-se a um pior escore de depressão.

Relationship between core function and pressure pain threshold in senior women with non-specific chronic low back pain: cross-sectional study / Relação entre a função do core e o limiar de dor a pressão em mulheres idosas com dor lombar crônica inespecífica: estudo transversal

ABSTRACT BACKGROUND AND OBJECTIVES: Chronic nonspecific low back pain (CNLBP) is a public health issue. Dysfunctions in muscle activation and spinal stability are estimated to directly impact pain intensity. Additionally, senior women experience greater decline in muscle function due to aging, rendering this demographic more susceptible to developing low back pain. The aim of this study was to analyze the correlation between core muscle instability, strength, and endurance with pressure pain threshold in senior individuals with CNLBP. METHODS: This is a quantitative observational study, with a descriptive cross-sectional design, conducted on women aged 60 to 79 years. The pressure pain threshold (PPT). The pressure pain threshold (PPT) was assessed using a pressure algometer applied to the paravertebral and anterior tibial musculature. Trunk instability was assessed on both a stable and an unstable seat, positioned atop a force platform that provided real-time displacement of the pressure center. Maximum isometric strength and endurance of trunk flexors and extensors were assessed using the McGill protocol. Person's correlations coefficient (r) was calculated, and the data were presented as mean and standard deviation. The significance level was set at p<0.05. RESULTS: This study included 49 senior women (67,3±5,6 years; body mass index of 28,5±5,2 kg/m2; pain intensity of 4,6±2,3 on a 0-10scale). No correlation was observed between PPT at L3, L5 and TA with lumbar instability, maximum isometric strength and trunk muscle endurance. CONCLUSION: In this study, no correlation was found between lumbar instability, maximum isometric strength and trunk muscle endurance with the PPT in senior women with CNLBP.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor lombar crônica inespecífica (DLCI) é um problema de saúde pública. Estima-se que disfunções na ativação muscular e na estabilidade da coluna possam repercutir diretamente na intensidade da dor. Além disso, em decorrência da idade, as mulheres idosas apresentam maior declínio na função muscular, tornando esse público mais suscetível a desenvolver a dor lombar. O objetivo deste estudo foi analisar a correlação entre instabilidade, força e resistência dos músculos do core com o limiar de dor por pressão em idosas com DLCI. MÉTODOS: Trata-se de um estudo observacional quantitativo, com delineamento transversal descritivo, realizado em mulheres com idade entre 60 e 79 anos. O limiar de dor por pressão (LDP) foi avaliado com um algômetro de pressão na musculatura paravertebral (bilateralmente ao processo espinhoso nível de L3 a L5) e cinco cm abaixo da tuberosidade da tibial direita no tibial anterior. A instabilidade de tronco foi avaliada em um assento estável e outro instável, posicionados sobre uma plataforma de força para análise do deslocamento do centro de pressão em tempo real. A força isométrica máxima e a resistência de flexores e extensores do tronco foi avaliada por meio do protocolo de McGill. Foi calculado o coeficiente de correlação de Pearson (r), os dados foram expressos em média e desvio padrão e o valor considerado significativo quando p<0,05. RESULTADOS: Participaram deste estudo 49 mulheres (67,3±5,6 anos; índice de massa corporal de 28,5±5,2 kg/m2; intensidade da dor 4,6±2,3 em uma escala de 0- a 10). Não foi encontrada correlação entre o LDP em L3, L5 e TA com instabilidade lombar, força isométrica máxima e resistência dos músculos do tronco. CONCLUSÃO: Não foi encontrada, neste estudo, uma correlação entre a instabilidade lombar, a força isométrica máxima e a resistência dos músculos do tronco com o LDP em mulheres idosas com DLCI.

Tracking and considerations on the therapeutic management of neuropathic pain in adult patients with sickle cell disease / Rastreamento e considerações sobre a conduta terapêutica na dor neuropática em pacientes adultos com doença falciforme

ABSTRACT BACKGROUND AND OBJECTIVES: Sickle cell disease is considered the most common hereditary disorder in Brazil. The chronic pain resulting from some complications of sickle cell disease is still poorly understood, inadequately described, and under-researched. This study aimed to characterize chronic pain in individuals with sickle cell disease, evaluate its treatment, and discuss the importance of studying it as a distinct pathology. METHODS: A cross-sectional study based on comparative analysis between two associations of sickle cell disease patients, one in Brazil and the other in France. The Pain Detect Questionnaire was used to assess neuropathic pain, and Odds Ratio was used to evaluate the strength of the association between opioid use and the recurrence of chronic painful crises. RESULTS: In Brazil, the Pain Detect questionnaire revealed that 55% of patients had a probable neuropathic component, 23% negative, and 22% uncertain. In France, the application resulted in 51% for probable presence, 29% for negative, and 20% for uncertain. All patients reported constant pain. As for the frequent use of opioids, the results were 62% in Brazil and 32% in France. The Odds Ratio calculation results were: OR 15.14 (95% CI = 4.777- 41.4, p < 0.0001) in Brazil; and OR 7.5 (95% CI = 2.121- 25.74, p = 0.0013) in France. CONCLUSION: While it is commonly believed that pain in sickle cell disease is primarily related to somatic and visceral tissue damage after vaso-occlusive events, this study indicated emerging evidence of neuropathic processes involved. Thus, there should be a significant concern about the management of chronic pain and particularly opioid dependence in Brazil.

RESUMO JUSTIFICATIVA E OBJETIVOS: Dentre as alterações hereditárias, a doença falciforme é considerada a mais comum no Brasil. A dor crônica decorrente de suas complicações ainda é mal compreendida, inadequadamente descrita e pouco pesquisada. O presente estudo teve como finalidade caracterizar a dor crônica em indivíduos com doença falciforme, avaliar o seu tratamento e discutir a importância de seu estudo como uma doença em si. METODOS: Estudo transversal, baseado na análise comparativa entre duas associações de indivíduos acometidos pela doença falciforme, com sede no Brasil e na França. Foi aplicado o questionário Pain Detect para avaliação da dor neuropática e a Odds Ratio para avaliar a intensidade de associação entre o uso de opioides e a recorrência de crises álgicas de cunho crônico. RESULTADOS: O questionário Pain Detect apontou que no Brasil 55% de pacientes da doença calciforme apresentam componente neuropático provável, 23% negativo e 22% incerto. Na França, os resultaram foram de 51% para componente provável, 29% negativo e 20% incerto. Dos acometidos pela doença, 100% relataram dores constantes, sendo que fizeram uso frequente de opioides 62% no Brasil e 32% na França. O cálculo do Odds Ratio apontou os seguintes resultados: OR 15,14 (IC 95% = 4,777- 41,4, p < 0,0001) no Brasil; e OR 7,5 (IC 95% = 2,121- 25,74, p = 0,0013) na França. CONCLUSÃO: Embora haja uma crença de que a dor na doença falciforme seja primariamente relacionada à lesão tecidual a nível somático e visceral após os eventos vasoclusivos, o estudo apontou evidências emergentes de processos neuropáticos envolvidos. Assim, deve haver uma preocupação quanto ao manejo da dor crônica e em especial à dependência química pelos opioides no Brasil.

Fear and avoidance of shoulder movement according to the International Code of Functioning: cross-sectional study / Medo e evitação de movimento do ombro segundo o Código Internacional de Funcionalidade: estudo transversal

ABSTRACT BACKGROUND AND OBJECTIVES: Shoulder pain is a limiting condition that has a major impact on daily activities and work. Knowing which specific activities involving the shoulder are associated with the occurrence of higher levels of pain may be of interest to professionals. The use of images of shoulder movements can be an effective tool to check the presence of pain and fear of movement, break down language and cultural barriers, and facilitate communication between professional and patient. The objectives of this study were: (1) to carry out a descriptive analysis of fear responses and movement avoidance based on passive viewing of images of shoulder movements based on the International Classification of Functioning, Disability and Health (ICF) codes; (2) to check whether there is a correlation between fear responses and movement avoidance with the Shoulder Pain and Disability Index (SPADI). METHODS: In this cross-sectional observational study, individuals with chronic shoulder pain were recruited. Participants responded to the Shoulder Pain and Disability Index (SPADI) and the TAMPA Scale of Kinesiophobia (TSK) to measure the intensity of shoulder pain and disability, and fear of movement, respectively. Participants viewed 58 movement images based on codes and descriptors from the third chapter of ICF. In addition, they responded to a numerical scale to judge fear of movement and a second numerical scale to judge movement avoidance. RESULTS: The study included 42 individuals. The activities belonging to the mobility subgroup (chapter 4), which refers to chapter 3 of the ICF, are those that present greater responses of fear and movement avoidance. Multiple regression resulted in a significant model [F(1, 40) = 31.119; p<0.001; R2 = 0.438], when verifying whether fear and movement avoidance responses related to ICF images are associated with SPADI in participants with chronic shoulder pain. The fear response is associated with SPADI (β=0.661; t=5.578; p<0.001), however, the avoidance response did not present a significant result with the scale (β=−0.063; t=-0.160; p=0.874). CONCLUSION: Movements that refer to mobility seem to be the most feared and avoided by people with chronic shoulder pain. Fear of movement is associated with shoulder disability.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor no ombro é uma condição limitante, que apresenta grande impacto nas atividades de vida diárias e no trabalho. Conhecer quais atividades específicas envolvendo o ombro estão associadas à ocorrência de maiores níveis de dor pode ser de interesse dos profissionais. A utilização de imagens de movimentos do ombro pode ser uma ferramenta eficaz para verificar a presença de dor e medo de movimento, quebrar barreiras de linguagem e culturais e facilitar a comunicação entre profissional e paciente. Os objetivos deste estudo foram: (1) realizar a análise descritiva das respostas de medo e evitação do movimento a partir da visualização passiva de imagens de movimentos do ombro baseadas nos códigos da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF); (2) verificar se há correlação das respostas de medo e evitação do movimento com o Índice de dor e Incapacidade do Ombro (SPADI). METODOS: Neste estudo observacional do tipo transversal foram recrutadas pessoas com dor crônica no ombro. Os participantes responderam ao Shoulder Pain and Disability Index (SPADI) e à Escala TAMPA de Cinesiofobia (TSK) para mensurar a intensidade da dor e incapacidade do ombro, e de medo do movimento, respectivamente. Os participantes visualizaram 58 imagens de movimentos baseadas em códigos e descritores do terceiro capítulo de Atividade e Participação da CIF. Além disso, responderam a uma escala numérica para julgar o medo do movimento e a uma segunda escala numérica para julgar a evitação ao movimento. RESULTADOS: Participaram do estudo 42 pessoas. As atividades pertencentes ao subgrupo mobilidade (capítulo 4), referente ao capítulo 3 da CIF, são as que apresentam maiores respostas de medo e evitação do movimento. A regressão múltipla resultou em um modelo significativo [F (1, 40) = 31, 119; p<0,001; R2 = 0,438], ao verificar se as respostas de medo e evitação do movimento referente às imagens da CIF estão associadas ao SPADI dos participantes com dor crônica no ombro. A resposta de medo é associada ao SPADI (β=0,661; t=5,578; p<0,001), porém a resposta de evitação não apresentou resultado significativo com a escala (β=−0,063; t=−0,160; p=0,874). CONCLUSÃO: Os movimentos que se referem à mobilidade parecem ser os mais temidos e evitados por pessoas com dor crônica no ombro. O medo do movimento está associado com a incapacidade do ombro.

Objetivo: Compreender o cotidiano de portadores de dor neuropática decorrente de lesão traumática. Metodologia: Pesquisa exploratória, descritiva, de abordagem qualitativa, com participantes selecionados por meio de mídias sociais. A coleta de dados foi realizada entre o período de julho a setembro de 2022, com indivíduos adultos que possuem diagnóstico de dor neuropática após lesão traumática. A coleta ocorreu por meio de um formulário online, utilizando um questionário sociodemográfico e um questionário aberto, para a captura de informações pertinentes sobre seu caso clínico e vivência com a dor crônica. Os dados foram analisados por meio de Bardin. Todos os preceitos éticos foram respeitados e o projeto foi aprovado sob parecer n.º 5.529.581 da Universidade Cesumar. Resultados: Participaram 15 pessoas com dor neuropática, com prevalência do sexo feminino (93,3%), com idade entre 41 a 50 anos (66,7%). Observou-se que 53,3% relataram comorbidades crônicas, sendo as doenças psíquicas, ansiolíticas e cardíacas mais citadas. Ainda, 33,3% dos participantes relataram que foram internados por causas de dores ou por tentativa de suicídio, 93,3% usam opióides e analgésicos potentes e ainda foram citados antidepressivos e ansiolíticos em 62% das respostas. Dentre os temas em destaque nas respostas, sobressaíram-se "Contexto e diagnóstico da dor neuropática; Vivência e frequência da dor; Apoio profissional e familiar diante da doença". Considerações Finais: Nesse sentido, a percepção acerca dos profissionais de saúde e valorização do médico para o tratamento da dor neuropática está relacionada, muitas vezes, à necessidade de aumentar o conhecimento referente ao manejo da dor e à utilização de opióides.

Objective: To understand the daily life of patients with neuropathic pain resulting from traumatic injury. Methodology: Exploratory, descriptive research, with a qualitative approach, with participants selected through social media. Data collection was carried out between July and September 2022, with adult individuals diagnosed with neuropathic pain after traumatic injury. The collection took place through an online form, using a sociodemographic questionnaire and an open questionnaire, to capture relevant information about their clinical case and experience with chronic pain. Data were analyzed using Bardin. All ethical precepts were respected and the project was approved by report n.º 5,529,581 of Cesumar University. Results: 15 people with neuropathic pain participated, with a prevalence of females (93.3%), aged between 41 and 50 years (66.7%). It was observed that 53.3% reported chronic comorbidities, with psychic, anxiolytic and cardiac diseases being the most cited. Also, 33.3% of the participants reported that they were hospitalized due to pain or a suicide attempt, 93.3% used opioids and potent analgesics, and antidepressants and anxiolytics were mentioned in 62% of the answers. Among the topics highlighted in the responses, the most important were "Context and diagnosis of neuropathic pain; Experience and frequency of pain; Professional and family support in the face of the disease". Final Considerations: In this sense, the perception of health professionals and the appreciation of physicians for the treatment of neuropathic pain is often related to the need to increase knowledge regarding pain management and the use of opioids.

Cervical anterior arthrodesis: autologous or synthetic graft? / Artrodese cervical via anterior: enxerto autólogo ou sintético? / Artrodesis cervical anterior: ¿injerto autologo o sintético?

ABSTRACT: Objective: To compare patients who underwent anterior cervical arthrodesis with autologous iliac crest graft and those who used synthetic graft. Methods: Analysis of 38 patients aged between 18 and 100 years with anterior cervical spondylosis of 1 or 2 levels in a spine surgery service. Results: degenerative cervical spine changes associated with cervicalgia and cervicobrachialgia. Excluded: previous cervical spine surgeries, fractures, or surgery above two levels. Two groups were formed with 19 patients, one using autologous graft and the other using synthetic tricalcium phosphate - a questionnaire assessed satisfaction (Oswestry and VAS) pre- and postoperatively. Bone consolidation was evaluated by tomography at nine months. Results: Mean ODI (Group 1) was 68.5% ± 4.6% preoperatively and 27.2% ± 3.8% postoperatively, being statistically relevant (p<0.001). VAS performed to evaluate the cervical region, Group 1 pre and post-op was considered statistically relevant (p<0.001). No significant difference was observed when comparing the mean values found in the postoperative period between Group 1 and Group 2 (p=0.463). Only two patients complained of chronic pain, representing 10% of the total. In nine-month tomography, 100% of patients in Group 1 and 100% of Group 2 showed bone consolidation, with no statistically relevant difference (p=0.676) between the groups. Conclusion: Similar functional and osteointegration outcomes were observed in both types of grafts. Synthetic graft minimizes the risks and complications of using allografts. Level of Evidence III; Retrospective comparative study.

Medicines for managing lower pain in patients with failed back surgery syndrome treated with neuromodulation / Medicamentos para manejo da dor em pacientes com síndrome da falha da cirurgia na coluna tratados com neuromodulação / Medicamentos para el manejo del dolor en pacientes con síndrome de cirugía fallida de columna tratados con neuromodulación

ABSTRACT: Objective: To compare the use of drugs to control low back pain in the pre- and postoperative periods among patients with Failed Back Surgery Syndrome (FBSS) undergoing neuromodulation. Methods: Retrospective observational study analyzing the medical records of patients with FBSS who underwent neuromodulation, followed up in an outpatient clinic from 2018 to 2020. The characteristics of the patients were evaluated: the use of medications, quality of life through the results of the Short Form 36 Health Survey Questionnaire (SF-36), and functional capacity using the Oswestry Disability Index (ODI) in the pre-surgical and post-surgical periods (06 months, 01 year). The criterion for establishing statistical significance was p≤0.05. Results: 56 patients were evaluated. There was a reduction in the use of pain control drugs after the institution of neuromodulation, including in the opioid class (d=0.81). An improvement was also observed in the ODI scores (p<0.001) and all the SF-36 domains (p<0.02) in the postoperative periods investigated. Conclusion: The data suggest that neuromodulation positively impacted back pain by reducing medication use and improving functional capacity and quality of life. Level of Evidence IV; Retrospective, Observational Study.

Impact of the COVID-19 pandemic on the perception of treatment and chronic musculoskeletal pain in users of a family health unit: qualitative study / Impacto da pandemia da COVID-19 na percepção do tratamento e da dor musculoesquelética crônica em usuários de uma unidade de saúde da família: estudo qualitativo

ABSTRACT BACKGROUND AND OBJECTIVES: Chronic pain has a high demand for health care due to its multifactorial cause. The COVID-19 pandemic represented a scenario of social stress, in which there was a reduction in care for chronic non-communicable diseases, including cases of chronic pain. The aim of this study was to understand the impacts of the pandemic on this population, considering the perception of pain, experience with care and mental health. METHODS: This is an exploratory case study using a qualitative methodology. An intentional sample of six patients diagnosed with chronic musculoskeletal pain, of both genders and aged between 30 and 70 was used. The individuals underwent a semi-structured interview, in which the data was analyzed by thematic analysis and coding. RESULTS: After the analysis, three themes emerged: 1) Multidimensional impact of pain and coping strategies; 2) Characteristics of the health service and individual-centered care; 3) Influence of pain on quality of life and perspective of future life. The impact of health care was a factor of anxiety and uncertainty about pain. It had repercussions on new coping strategies, such as telehealth. In this context, Primary Health Care was a scenario capable of managing the short- and long-term quality of life of individuals with chronic pain. CONCLUSION: This study contributed to understanding the impact of the COVID-19 pandemic on individuals with chronic pain, which represents a challenge to current care.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor crônica apresenta alta demanda de assistência à saúde, devido a sua causa multifatorial. A pandemia da COVID-19 representou um cenário de estresse social, em que houve redução de atendimentos às doenças crônicas não transmissíveis, incluindo os casos de dores crônicas. O objetivo deste estudo foi compreender os impactos da pandemia para este público, considerando a percepção da dor, experiência com assistência e saúde mental. MÉTODOS: Trata-se de um estudo de caso exploratório de metodologia qualitativa. Foi utilizada uma amostra intencional de seis pacientes com diagnóstico de dor musculoesquelética crônica, de ambos os sexos e com idade entre 30 e 70 anos. Os indivíduos passaram por uma entrevista semiestruturada, na qual os dados foram analisados por análise temática e codificação. RESULTADOS: Após a análise, emergiram três temas: 1) Impacto multidimensional da dor e estratégias de enfrentamento; 2) Características do serviço de saúde e atenção centrada no indivíduo; 3) Influência da dor na qualidade de vida e na perspectiva de vida futura. O impacto na assistência à saúde foi um fator de ansiedade e incertezas sobre a dor. Isso repercutiu em novas estratégias de enfrentamento, como os teleatendimentos. Nesse contexto, a Atenção Primária à Saúde foi o cenário capaz de gerenciar a qualidade de vida a curto e a longo prazo dos indivíduos com dor crônica. CONCLUSÃO: Este estudo contribuiu para a compreensão do impacto da pandemia da COVID-19 em indivíduos com dor crônica, o qual representa desafios à assistência atual.

How the practice of Mindfulness influences the treatment of patients with chronic non-cancer pain associated or not with other therapies: systematic review / Como a prática de Mindfulness influencia no tratamento de pacientes com dor crônica não oncológica associado ou não a outras terapias: revisão sistemática

ABSTRACT BACKGROUND AND OBJECTIVES: Chronic pain has a significant impact on patients' quality of life and the use of drug therapy is often insufficient. Therapies based on Mindfulness come in different forms and have been used as a strategy to manage this condition. Practices can guide attention to the present, help reinterpret pain and improve physical and emotional control skills via the cingulate cortex, somatosensory cortex, parietal operculum, cuneus, and anterior insula. This study seeks to evaluate the results of Mindfulness in terms of its influence on the quality of life of patients with chronic non-cancer pain and the neural changes that this practice promotes, such as greater or lesser activation or variation in size of areas as insula and cingulate cortex, and how these interfere with the perception of pain, with the aim of verifying the applicability of Mindfulness as a complementary method to treatment in this group of patients. CONTENTS: Systematic Review submitted to PROSPERO datadase under number 359011. The search was carried out in the Pubmed, Medline, LILACS and DIALNET databases between 2019 and 2022 with the descriptors and Boolean operator [(MINDFULNESS) AND (CHRONIC PAIN)]. The selection of articles includes randomized clinical trials, cohort studies and case control studies in English, Spanish and Portuguese languages. The risk of bias was assessed using ROB2 and the quality of evidence using GRADE. After analysis, ten studies were assessed as essential for this review. Articles that addressed Mindfulness intervention for chronic pain that responded and added information to the research question were included and articles that did not focus on "Mindfulness" and "chronic pain", studies without free access and texts whose results were not published up to the date of the search were excluded. To analyze Mindfulness therapies, the majority of studies cover more than 50 patients and use scales such as the Brief Pain Inventory (BPI-DPN Q4), Patient Global Impression of Change (PGIC), Five Facet Mindfulness Questionnaire (FFMQ), Chronic Pain Acceptance Questionnaire (CPAQ) and Pain Catastrophizing Scale (PCS). CONCLUSION: The practice of Mindfulness can reduce chronic pain and improving its perception, acceptability and quality of life by enabling the reduction of suffering, anxiety and stress associated with pain through neural changes. As there are limitations in the studies regarding the specific target population and standardization of assessment, it is recommended that future articles address the practice in children, the elderly and athletes with chronic pain, in addition to a detailed methodology to evaluate and promote the sessions. It should be noted that Mindfulness is not a cure for chronic pain, however it presents safety and effectiveness in its different application protocols, with a level of evidence similar to cognitive behavioral therapy.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor crônica tem um impacto significativo na qualidade de vida dos pacientes e o uso de terapia farmacológica muitas vezes é insuficiente. As terapias baseadas em Mindfulness (Atenção Plena) apresentam-se de diversas formas e têm sido utilizadas como estratégia no manejo dessa condição. As práticas podem conduzir a atenção ao presente, auxiliar na reinterpretação da dor e aprimorar habilidades de controle físico e emocional via córtex cingulado, somatossensorial, opérculo parietal, cúneo e ínsula anterior. O objetivo deste estudo foi avaliar a Mindfulness quanto a sua influência na qualidade de vida dos pacientes com dor crônica não oncológica e as alterações neurais que essa prática promove, como maior ou menor ativação ou variação de tamanho de áreas como a ínsula e córtex cingulado, e como estas interferem na percepção da dor, tendo como finalidade verificar a aplicabilidade da Atenção Plena como método complementar ao tratamento nesse grupo de pacientes. CONTEÚDO: Revisão Sistemática submetida no banco de dados PROSPERO sob o número 359011. Realizou-se a busca nas bases de dados Pubmed, Medline, LILACS e DIALNET entre 2019 e 2022 com os descritores e operador booleano [(MINDFULNESS) AND (CHRONIC PAIN)]. Incluiu-se na seleção de artigos ensaios clínicos randomizados, estudos de coorte e estudos de caso controle nos idiomas inglês, espanhol e português. O risco de viés foi avaliado pelo ROB2 e a qualidade de evidência por meio do GRADE. Após análise, 10 estudos foram avaliados como essenciais para esta revisão. Foram incluídos os artigos que abordavam intervenção em Mindfulness para dor crônica que responderam e agregaram informações à pergunta da pesquisa e excluídos os artigos que não possuem o foco em "Mindfulness" e "dor crônica", estudos sem livre acesso e textos cujos resultados não foram publicados até a data da busca. Para analisar as terapias de Mindfulness, os estudos, em sua maioria, abordam mais de 50 pacientes e usam escalas como o Brief Pain Inventory (BPI-DPN Q4), Patient Global Impression of Change (PGIC), Five Facet Mindfulness Questionnaire (FFMQ), Chronic Pain Acceptance Questionnaire (CPAQ) e Pain Catastrophizing Scale (PCS). CONCLUSÃO: A prática de Mindfulness é capaz de diminuir a dor crônica e melhorar sua percepção, aceitabilidade e qualidade de vida ao possibilitar a redução do sofrimento, ansiedade e estresse associados à dor por meio de alterações neurais. Por haver limitações nos estudos com relação à população-alvo específica e à padronização de avaliação, recomenda-se que artigos futuros abordem a prática em crianças, idosos e atletas com dor crônica, além de metodologia detalhada para avaliar e promover as sessões. Ressalta-se que a Mindfulness não é uma cura para a dor crônica, no entanto apresenta segurança e eficácia em seus diferentes protocolos de aplicação, com nível de evidência similar à terapia cognitiva comportamental.
