Estudio transversal de prevalencia y características del dolor crónico en pacientes con esquizofrenia / Prevalence and features of chronic pain among patients with schizophrenia

Background: People with schizophrenia generally refrain from manifesting somatic symptoms, and may not complain of pain. Therefore these patients may have an insensitivity to pain. Aim: To determine the prevalence of chronic pain in a sample of patients with schizophrenia. Patients and Methods: The McGill Pain Questionnaire (MPQ) was answered by 79 outpatients with schizophrenia with a mean age of 47 years (67% men) attended at a public hospital in Chile. Results: Chronic pain, defined as lasting more than six months, was reported by 15.2 % of patients. Acute pain was reported by 63% of patients. No significant differences were observed in sociodemographic characteristics or duration of illness between patients with acute or chronic pain. The assessment of the different pain dimensions showed a predominance of sensory and affective components, with pain rating indexes of 0.82 and 0.71, respectively. Conclusions: These results indicate that the prevalence of pain among people with schizophrenia, is similar to that of the general population.

Introducción: El dolor crónico no oncológico (DCNO) es un tema de salud pública con alta prevalencia en Chile. Existe evidencia sobre la necesidad de abordaje multidisciplinario por profesionales capacitados. El año 2013 se crea el policlínico de DCNO por la especialidad de fisiatría, coordinando atención con anestesista para intervencionismo. El Objetivo de este trabajo es conocer las características clínicas de los usuarios en control en policlínico de DCNO. Material y Método: Estudio retrospectivo, descriptivo, observacional. Desde la base de datos de usuarios atendidos entre inicios del 2013 y mayo 2018 de policlínico DCNO del Servicio de Medicina Física y Rehabilitación del HHHA; se recogen variables como: sexo, edad, etnia, previsión, ruralidad, diagnóstico ingreso, intensidad dolor (según NRS), tratamiento farmacológico, entre otras. Para manejo estadístico se utiliza planilla Excel, con pruebas paramétricas (promedio, mínimo, máximo), tablas y gráficos. Resultados: Los usuarios en control en el periodo fueron 125, con un 67,2% de mujeres y una mediana de edad de 55,5 años (mínimo 12, máximo 88). El 58,4% tenía como previsión Fonasa B, 83.2% presenta domicilio urbano, 16% etnia mapuche. El mayor número de ingresos ocurrió el año 2017. Las derivaciones provienen de especialidades médicas (25,6%), quirúrgicas (29,6%), fisiatría (24,8%). Según tipo de dolor, el 49,6% es nociceptivo, 32% neuropático y 18,4% mixto. Al ingreso, la intensidad fue 90% severa y 10% moderada (según NRS). Los principales diagnósticos de ingreso fueron 44,8% patología de columna, 27,2% patología neurológica, 12,8% fibromialgia y 15,2% otras. Al ingreso mayoría de los usuarios usaba paracetamol, tramadol gotas o comprimidos; actualmente 23% recibe metadona, 8% parches buprenorfina, 20% paracetamol, 27,2% tramadol en gotas/comprimidos y 23,2% pregabalina/ gabapentina. En el 51,2% se requirió cambio de terapia; en el 79,7% por analgesia insuficiente y 20,3% por reacción adversa a medicamentos. Se realizó derivación a intervencionismo en 21 usuarios. 15 usuarios fueron dados de alta de policlínico DCNO (12%). Conclusiones: Estos datos servirán para futuras investigaciones y medir impacto de nuestras intervenciones. Se presenta como desafío aumentar recursos de la unidad, demostrar beneficio de atención interdisciplinaria y bajar costos para la institución.

Introduction: Non-oncological chronic pain (NOCP) is a public health issue with high prevalence in Chile. There is evidence of the need for a multidisciplinary approach by trained professionals. In 2013, the NOCP polyclinic was created for the specialty of physiatry, coordinating care with anesthesiologist for interventionism. The objective of this work is to know the clinical characteristics of users in control in NOCP polyclinic. Material and Methods: Retrospective, descriptive, observational study. From the database of users attended between the beginning of 2013 and May 2018, from the NOCP polyclinic of the Physical Medicine and Rehabilitation Service of the HHHA; variables such as: sex, age, ethnicity, foresight, rurality, income diagnosis, pain intensity (according to NRS), and pharmacological treatment, among others are collected. For statistical management Excel spreadsheet isused, with parametric tests (average, minimum, maximum), tables and graphs. Results: The users in control in the period were 125, with 67.2% of women, a median age of 55.5 years (minimum 12, maximum 88). 58.4% had Fonasa B as a forecast, 83.2% have an urban address, 16% Mapuche ethnicity. The highest number of admissions occurred in 2017. The referrals come from medical specialties (25.6%), surgical specialties (29.6%), and physiatry (24.8%). According to type of pain, 49.6% is nociceptive, 32% neuropathic and 18.4% mixed. At admission, the intensity was 90% severe and 10% moderate (according to NRS). The main diagnoses of admission were 44.8% spinal pathology, 27.2% neurological pathology, 12.8% fibromyalgia and 15.2% others. On admission, most users used paracetamol, tramadol drops or tablets; currently 23% receive methadone, 8% patches buprenorphine, 20% paracetamol, 27.2% tramadol in drops / tablets and 23.2% pregabalin / gabapentin. In 51.2%, therapy change was required; in 79.7% due to insufficient analgesia and 20.3% due to adverse drug reaction. A derivation to interventionism was carried out in 21 users. 15 users were discharged from polyclinic DCNO (12%). Conclusions: These data will serve for future research and measure the impact of our interventions. It is a challenge to increase the resources of the unit, demonstrate the benefit of interdisciplinary attention and lower costs for the institution.

Acute and chronic back pain in adults and elderly in southern Brazil: a population-based study / Dor aguda e crônica nas costas em adultos e idosos no sul do Brasil: um estudo de base populacional

Aims: to determine the prevalence of acute and chronic back pain and associated factors and identify the consequences of this pain in adults and the elderly in southern Brazil. Methods: cross-sectional study conducted in 2019, in Criciúma, Santa Catarina, in individuals aged 18 and over. Acute back pain was pain in the cervical, thoracic, or lumbar regions not exceeding 3 months and chronic pain as pain for 3 months or more. Bivariate analyzes and multinomial logistic regression were performed. Results: among the 820 participants, the prevalence of back pain was 67.0%, acute pain 39.3% (95% CI: 35.5% to 43.3%) and chronic pain 27.4% (95% CI: 24.5% to 30.4%). Acute back pain was associated with women, overweight, obesity, and with WMSD/RSI, while chronic pain chronic pain was found mostly in women, being related to leisure inactivity ...were female, leisure inactivity, falls, Work-related musculoskeletal disorder/repetitive strain injury, and arthritis/rheumatism. Conclusions: acute pain was greater among overweight/obese and chronic pain contribute to absenteeism and demand for health services.

Objetivos: determinar a prevalência de dores aguda e crônica nas costas e fatores associados e identificar as consequências dessas dores em adultos e idosos no Sul do Brasil. Métodos: estudo transversal realizado em 2019, em Criciúma, Santa Catarina, em indivíduos com 18 anos ou mais. Dor aguda foi a dor nas regiões cervical, torácica ou lombar não superior a três meses e dor crônica como dor por três meses ou mais. Foram realizadas análises bivariadas e regressão logística multinomial. Resultados: entre os 820 participantes, a prevalência de dor nas costas foi de 67,0%, dor aguda 39,3% (IC 95%: 35,5% a 43,3%) e dor crônica 27,4% (IC 95%: 24,5% a 30,4%). A dor aguda nas costas foi associada a mulheres, sobrepeso, obesidade e a distúrbio musculoesquelético relacionado ao trabalho/lesão por esforço repetitivo, enquanto a dor crônica, foi constatada majoritariamente em mulheres, tendo relação com sedentarismo, quedas, distúrbio musculoesquelético relacionado ao trabalho/lesão por esforço repetitivo e artrite/reumatismo. Conclusões: a dor aguda mais associada a excesso de peso/obesidade e a dor crônica contribuiu para o absenteísmo e procura pelos serviços de saúde.

Functional capacity, risk of falling and chronic pain in older adults during the COVID-19 pandemic: a telemonitoring study / Capacidade funcional, risco de queda e dor crônica em idosos durante a pandemia de COVID-19: um estudo de telemonitoramento

OBJECTIVE: To compare active and sedentary older adults regarding functional capacity, risk of falling, and chronic pain in a population assisted by telemonitoring during the pandemic lockdown. METHODS: This analytical, cross-sectional study included 104 older adults who were telemonitored during the COVID-19 lockdown by a team from a Brazilian Unified Health System outpatient clinic specializing in geriatrics and gerontology. A structured interview was used to collect data. Following normality testing with the Shapiro-Wilk test, Student's t-test was used for group comparisons. Associations were analyzed using the χ2 test, and the odds ratio was calculated in a 2x2 table of sedentarism and falls in the last six months. The data were analyzed using SPSS version 26.0, with p ≤ 0.05 considered significant. RESULTS: The 57 active older adults had a lower rate of continuous medication use (24.84 vs 27.62%), fewer falls (50 vs 32.11%), less pain (12.31 vs 3.83%), and greater independence in basic activities of daily living (44.39 vs 26.46%). CONCLUSIONS: Older adults who were physically active in the midst of social distancing had better functional capacity in basic activities of daily living, fewer falls, and less pain than their sedentary peers. Independence in instrumental activities of daily living did not differ significantly between the groups.

comparar idosos ativos e sedentários no que diz respeito à capacidade funcional, risco de quedas e dores crônicas dentro de uma população em distanciamento físico, atendida por telemonitoramento. METODOLOGIA: estudo analítico, transversal, de abordagem quantitativa com 104 idosos que vivenciavam a pandemia da COVID-19 em distanciamento físico, acompanhados por telemonitoramento pela equipe de um ambulatório especializado em geriatria e gerontologia pertencente ao Sistema Único de Saúde e classificados em dois grupos comparados. Para as comparações por grupos, utilizou-se do teste t de Student, seguindo análise prévia de parametrização pelo teste de Shapiro-Wilk. A análise de associação foi realizada pelo teste χ2 e em proporções 2x2 calculou-se a razão de chances (Odds Ratio), entre ser sedentário e quedas nos últimos seis meses. Estatística realizada no Statistical Package for the Social Sciences versão 26.0, adotando significância com valor de p ≤ 0,05. Para coleta de dados, utilizou-se um roteiro de entrevista estruturada. RESULTADOS: 57 idosos ativos utilizavam menor quantidade de medicamentos de uso contínuo (24,84 vs 27,62%), apresentavam menos quedas (50 vs 32,11%) e dor (12,31 vs 3,83%), e eram mais independentes para atividades básicas de vida diária (44,39 vs 26,46%). CONCLUSÕES: idosos praticantes de exercício físico durante a pandemia da COVID-19 apresentaram melhor capacidade funcional no que diz respeito às atividades básicas de vida diária, redução na ocorrência de quedas e dor quando comparados aos idosos sedentários na mesma condição. Não se observou diferença significativa para independência nas atividades instrumentais de vida diária entre tais idosos.

Factores asociados a la ideación suicida y el dolor crónico en pacientes adultos mayores asistidos en un hospital general de la ciudad de Buenos Aires / Associated factors with suicidal ideation and chronic pain in elderly patients assisted in a general hospital of the city of Buenos Aires

Introducción: el siguiente estudio tuvo como finalidad explorar algunas características demográficas asociadas al dolor crónico y el desarrollo de ideas de suicidio en una población de pacientes mayores de 65 años. Método: se realizó un estudio observacional y analítico de corte transversal mediante el relevamiento de datos a partir historias clínicas de pacientes mayores de 65 años que concurrieron a los consultorios externos del equipo de geriatría del Servicio de Psiquiatría del Hospital Italiano de Buenos Aires, entre junio de 2018 y diciembre de 2018. Resultados: se incluyó en el estudio un total de 222 pacientes, de los cuales 50 (23%) presentaron indicadores de dolor crónico y 33 pacientes (14,6%) lo hicieron de ideación suicida. Mediante estudio de correlación se estableció que estar ocupado, padecer dolor crónico y haber tenido más de una internación psiquiátrica son factores que incrementan el riesgo de presentar ideación suicida. Las variables ideación suicida, edad, y el estado civil ‒separado o divorciado en comparación con estar casado‒ son factores asociados a la presencia de dolor crónico. Conclusiones: el dolor crónico y la ideación suicida son factores que contribuyen a aumentar la fragilidad en personas mayores y deben ser estudiados en mayor profundidad para comprender los distintos modos de expresión de la patología psiquiátrica en esta población. (AU)

Introduction: the following study aimed to explore some demographic characteristics associated with chronic pain and the development of suicidal ideas in a population of patients over 65 years. Method: an cross-sectional observational and analytical study was carried out by collecting data from clinical histories of patients over 65 years of age who attended the external offices of the geriatrics team of the Psychiatry service of the Italian Hospital of Buenos Aires between June 2018 and December 2018. Results: a total of 222 patients were included in the study, of which 50 (23%) presented indicators of chronic pain and 33 patients (14.6%) had suicidal ideation. A correlation study established that being employed, suffering from chronic pain and having had more than one psychiatric hospitalization are factors that increase the risk of presenting suicidal ideation. The variables suicidal ideation, age, and separated or divorced marital status compared to being married are factors associated with the presence of chronic pain. Conclusions: chronic pain and suicidal ideation are factors that contribute to increasing frailty in elderly patients and should be studied in greater depth to understand the different modes of expression of psychiatric pathology in this population.

Avaliação dos fatores determinantes da autoeficácia em idosos da comunidade com dor crônica musculoesquelética / Evaluation of self-efficacy determinants in community-dwelling older adults with chronic musculoskeletal pain

INTRODUÇÃO: A autoeficácia pode ser definida como a força das convicções que se tem de poder executar determinada atividade obtendo o resultado esperado. Ela pode funcionar como potente mediador entre a dor crônica musculoesquelética e a maneira como o idoso lida com suas próprias incapacidades. OBJETIVO: Avaliar os fatores determinantes das crenças de autoeficácia e do medo do exercício em idosos da comunidade com dor crônica musculoesquelética. METODOLOGIA: Estudo transversal com idosos que sofrem de dor crônica musculoesquelética. Incluíram-se apenas indivíduos da área urbana que relataram dor há mais de três meses. Selecionou-se a amostra de forma não probabilística por conveniência. As variáveis estudadas basearam-se em dados sociodemográficos, na caracterização da dor pelo inventário breve de dor e pela escala Leeds Assessment of Neuropathic Symptoms and Signs (LANSS), na autoeficácia pela escala de autoeficácia para dor crônica e, para a crença sobre o exercício físico, elaboraram-se questões simples. Para as análises estatísticas aplicaram-se frequência absoluta e relativa, teste x2 e teste de Mann-Whitney U quando pertinentes. RESULTADOS: A amostra compreendeu 193 idosos, em sua maioria mulheres com baixa escolaridade. A autoeficácia foi mais bem avaliada por idosos que moravam sós e por aqueles que foram classificados com dor exclusivamente nociceptiva. CONCLUSÃO: Ainda que possuam dores crônicas, idosos com melhor autoeficácia sentem-se confiantes na realização de suas tarefas e possuem melhor capacidade para o enfrentamento das mudanças relacionadas ao envelhecimento e para o autocuidado.

INTRODUCTION: Self-efficacy is defined as the strength of a person's convictions in being able to perform a given activity and obtain the expected result. It may act as a potent mediator between chronic musculoskeletal pain and how older adults cope with their disabilities. OBJECTIVE: To evaluate the determinants of self-efficacy beliefs and fear of physical exercise in community-dwelling older adults with chronic musculoskeletal pain. METHODS: This cross-sectional study recruited older adults with chronic musculoskeletal pain. Only individuals living in an urban area in southern Brazil and who reported pain for more than 3 months were included. A convenience sample was selected in a nonprobabilistic fashion. The study variables consisted of sociodemographic data; pain based on the Brief Pain Inventory and the Leeds Assessment of Neuropathic Symptoms and Signs for Patients with Chronic Pain; and self-efficacy based on the Chronic Pain Self-Efficacy Scale. Also, simple questions were created for physical exercise beliefs. For statistical analysis, absolute and relative frequency, x2 test, and Mann-Whitney U test were used as appropriate. RESULTS: The sample consisted of 193 older adults, mostly women with low level of education. Self-efficacy was best rated by older adults living alone and by those who were classified as exclusively nociceptive pain. CONCLUSION: Despite having chronic pain, older adults with higher self-efficacy feel confident in performing their tasks and have greater ability to cope with changes related to aging and to engage in self-care.

Diagnóstico de espondiloartrite axial em pacientes com fibromialgia / Axial spondyloarthritis diagnosis in fibromyalgia patients

Objetivo: Avaliar pacientes com fibromialgia e dor lombar, bus- cando características clínicas de espondiloatrites axiais. Méto- dos: Neste estudo transversal, cem pacientes com fibromialgia e idades entre 18 e 65 anos foram avaliados. A avaliação consis- tiu em um questionário baseado no braço clínico dos critérios Assessment of Spondyloarthritis International Society para diag- nóstico de espondiloatrites axiais e um questionário de impacto da fibromialgia (Revised Fibromyalgia Impact Questionnaire). Re- sultados: Quando o braço clínico da Assessment of Spondyloar- thritis International Society foi aplicado em pacientes com fibro- mialgia e dor lombar, 80% dos pacientes preencheram os critérios para diagnóstico de espondiloatrites axiais. As principais carac- terísticas de espondiloatrite axial foram dor lombar inflamatória, boa resposta a drogas anti-inflmatórias não esteroidais, artrite e entesite. Pacientes com critérios de espondiloatrites axiais posi- tivos apresentaram maiores níveis séricos de proteína C-reativa (p=0,00035). O valor médio do Revised Fibromyalgia Impact Ques- tionnaire para todos os pacientes avaliados foi 63,6, e não houve di- ferença entre os pacientes que preencheram os critérios e aqueles que não preencheram. Conclusão: Pacientes com fibromialgia e dor lombar frequentemente apresentam características clínicas de espondiloatrite axial, e aqueles que preencheram os crité- rios clínicos para espondiloatrites axiais também apresentaram maiores níveis séricos de proteína C-reativa.

Objective: To evaluate patients with fibromyalgia and back pain for clinical features of axial spondyloarthritis. Methods: In this cross-sectional study, one hundred fibromyalgia patients between 18 and 65 years old were assessed. The assessment consisted of a questionnaire based on the clinical arm ofthe Assessment of Spondyloarthritis International Society criteria for the diagnosis of axial spondyloarthritis and a questionnaire on the impact of fibromyalgia (Revised Fibromyalgia Impact Questionnaire). Re- sults: When the clinical arm of the Assessment of Spondyloarthri- tis International Society was applied in patients with fibromyal- gia and back pain, 80% of the patients met the clinical criteria for diagnosis of axial spondyloarthritis. The main features of axial spondyloarthritis in fibromyalgia patients were inflammatory back pain, good response to non-steroidal anti-inflammatory drugs (NSAIDs), arthritis, and enthesitis. Patients with positive axial spondyloarthritis criteria presented with higher C- reac- tive protein levels (p=0.00035). The mean value of the Revised Fibromyalgia Impact Questionnaire for all patients assessed was 63.6 and there was no difference between patients that met the criteria for axial spondyloarthritis and those who did not. Con- clusion: Patients with fibromyalgia and back pain often present clinical features of axial spondyloarthritis, and those who met the clinical criteria for axial spondyloarthritis also presented with higher levels of C-reactive protein.

Prevalência e fatores associados a problema crônico de coluna em mulheres em idade fértil / Prevalence and factors associated with chronic back problem in women of childbearing age

Resumo No Brasil, dados da Pesquisa Nacional de Saúde (PNS) estimaram 27,0 milhões de pessoas (18,5%) que referiram Problema Crônico de Coluna (PCC), afetando mais mulheres que homens. Este trabalho tem o objetivo de identificar, entre as mulheres em idade fértil, os fatores associados ao PCC. Trata-se de um estudo transversal realizado com dados da PNS, em que a variável dependente foi a prevalência de PCC, enquanto que os fatores associados incluíram itens sociodemográficos, hábitos de vida, histórico reprodutivo, estado nutricional, diagnóstico de depressão e percepção de saúde. Foram avaliadas 22.621 mulheres com idade entre 18 e 49 anos e, destas, 14,8% referiram ter PCC. Os fatores de risco estudados foram: aumento da faixa etária; viver com cônjuge/companheiro; multiparidade; ser tabagista; sobrepeso ou obesidade, ter Circunferência da Cintura (CC) acima de 80cm e índice Circunferência/Estatura (C/E) acima de 0,5; autopercepção de saúde negativa; e diagnóstico de depressão. O único fator de proteção encontrado foi escolaridade. As associações observadas concluem que idade, viver com cônjuge/companheiro, tabagismo, multiparidade, sobrepeso e obesidade, risco aumentado para doenças cardiovasculares, diagnóstico de depressão e autopercepção de saúde negativa estão associados ao desenvolvimento de PCC em mulheres de idade fértil.

Abstract Chronic Back Problem (CBP) is a public health concern. In Brazil, data from the National Health Survey (PNS) estimated 27.0 million people (18.5%) who reported CBP, affecting more women than men. This study aims to identify the factors associated with CBP among women of childbearing age. It is a cross-sectional study carried out with data from the PNS, where the dependent variable was the prevalence of CBP, and associated factors included socio-demographic items, life habits, reproductive history, nutritional status, diagnosis of depression and health perception. A total of 22,621 women aged 18 to 49 years were interviewed. Of these, 14.8% reported having CBP. The risk factors studied were: increased age; living with spouse; multiparity; smoking; overweight or obese, having Waist Circumference (WC) above 80cm and Circumference/Height (C/E) index above 0.5; negative self-perception of health; and depression. The only protective factor associated with CBP risk reduction was education level. We conclude that age, living with a spouse/partner, smoking, multiparity, being overweight or obese, increased risk for cardiovascular diseases, depression and negative self-perceived health are associated with the development of CBP in women of childbearing age.

Prevalencia de dolor crónico en pacientes con distrofia muscular de Duchenne en etapas no ambulantes / Prevalence of chronic pain in Duchenne muscular dystrophy patients in non-ambulatory stage

INTRODUCTION: Chronic pain is a frequent symptom in patients with Duchenne muscular dystrophy (DMD) as reported, in up to 73%, affecting their normal activities, participation and quality of life; however it is an underdiagnosed symptom, and therefore, undertreated. OBJECTIVE: to establish the prevalence of chronic pain in a population with non-ambulatory DMD attending Instituto Teletón Santiago (ITS). MATERIALS AND METHODS: Descriptive, cross-sectional study in DMD patients of Instituto Teletón Santiago, of 12 years old and older, who were in an early or late non-ambulatory stage. By means of a questionnaire designed by the authors, adapted from 'Brief Pain Inventory' and 'ID-Pain', and administered via telephone, it was possible to obtain data on the presence of acute, chronic pain and its intensity, frequency, location, clinical characteristics and interference with daily life activities and the use of analgesic drugs. Data collected helped to do an estimation of the prevalence of pain in the last week, chronic pain as well as summary measures for location, intensity and clinical characteristics. RESULTS: of 74 active patients with DMD and in compliance with the inclusion criteria, 23 subjects responded the questionnaire (31% response rate); average age was 18.3 years, and 9 months since loss of walking ability; prevalence of acute pain was 13% and 13% for chronic pain; most common localization was in the hips, followed by neck, spine and lower limbs; duration and frequency were variable and of moderate intensity. CONCLUSION: Pain has a lower prevalence in the studied population compared to the literature, however, it affects multiple locations and has an impact on their daily activities, and therefore it is important to record the presence of chronic pain in clinical practice. It is necessary to get a higher response rate in future studies and quantify pain with an instrument developed especially for this population.

INTRODUCCIÓN: El dolor crónico es un síntoma frecuente en pacientes con distrofia muscular de Duchenne (DMD) reportado en hasta un 73%, afectando las actividades, participación y calidad de vida; sin embargo, es un síntoma subdiagnosticado y por ende subtratado. OBJETIVO GENERAL: Determinar prevalencia de dolor crónico en población con DMD en etapa no ambulante que se atiende en Instituto Teletón Santiago (ITS). MATERIALES Y MÉTODOS: Estudio descriptivo, transversal en pacientes con DMD, activos en Instituto Teletón Santiago, de 12 años y más de edad, que se encontraban en etapa no ambulante temprano o tardío. Mediante la aplicación de un cuestionario diseñado por los autores adaptando Brief Pain Inventory e ID-Pain, aplicado vía telefónica, se obtuvo datos sobre la presencia de dolor agudo, crónico, intensidad, frecuencia, localización, tiempo de duración, características clínicas del dolor, interferencia en actividades de vida diaria y uso de fármacos analgésicos. Con los datos recolectados se estimó la prevalencia de dolor crónico, de la última semana y medidas de resumen para localización, intensidad y características clínicas. RESULTADOS: De 74 pacientes activos con diagnóstico de DMD que cumplían criterios de inclusión, se encuestaron 23 sujetos (porcentaje de respuesta de 31%); edad promedio de 18,3 años y 9 años desde pérdida de la marcha; la prevalencia de dolor agudo fue de 13% y de dolor crónico 13%; la localización más frecuente fue en las caderas, seguido por cuello y columna y extremidades inferiores, de duración y frecuencia variable e intensidad moderada. CONCLUSIÓN: El dolor tiene menor prevalencia en la población estudiada en relación con la literatura, sin embargo, afecta múltiples localizaciones e impacta en sus actividades de la vida diaria, por lo que es importante consignar la presencia de dolor crónico en la práctica clínica. Se hace necesario obtener un mayor porcentaje de respuesta en futuros estudios y cuantificar el dolor con un instrumento confeccionado especialmente para esta población.

Implementing a chronic pain ambulatory care: preliminary results / Implementação de atendimento ambulatorial para dor crônica: resultados preliminares

Abstract Background and objectives: Pain is one of the most common reason for seeking medical care. This study aimed to analyze patients with chronic pain in Maricá, Rio de Janeiro State, Brazil. Methods: A transversal retrospective study with 200 patients, who were treated in ambulatory care in a public hospital from June 2014 to December 2015. The variables considered were: pain intensity, type of pain, anatomical location, diagnosis and treatment. The data were statistically analyzed, the Fisher's exact test was applied, and the probability p was significant when ≤0.05. Results: We analyzed 200 patients with chronic pain, most of them female (83%). Mean age was 58.6 ± 13.01 years old. The patients were classified in groups by age, six groups with ten years of difference between them. Main age range was the 50-59 years old group, with 49 females (32%) and 5 males (15%). About 65.5% of the total of patients (131) had severe pain (Numeric Rating Sacale was 9.01). Mixed pain was predominant, affecting 108 patients (92 females and 16 males, what represents 55% and 47% of the total of females and males, respectively, that participate in the study). The most prevalent anatomical pain (159 patients, 131 females and 28 males) was in the lower limbs. Lower back pain was present in 113 of the 200 patients (94 females and 19 males). In the 30-39, 50-59, 60-69 years old group, the results for pain locations were significant: p = 0.01, p = 0.0069, p = 0.0003, respectively. Conclusion: The prevalence of chronic pain was associated with females in 50-59 years old and severe mixed pain. Pain was located mainly in lower limbs and lumbar region. The most frequent diagnosis was low back pain followed by fibromyalgia. The patients were informed about their disease and treatment.

Distribution of depression, somatization and pain-related impairment in patients with chronic temporomandibular disorders

Abstract Objective the aim of this study was to describe the frequency of psychosocial diagnoses in a large sample of patients attending a tertiary clinic for treatment of temporomandibular disorders (TMD). Material and Methods six hundred and ninety-one patients who sought treatment for pain-related TMD were selected. Chronic pain-related disability (Graded Chronic Pain Scale, GCPS), depression [Symptoms Checklist-90 (SCL-90) scale for depression, DEP] and somatization levels (SCL-90 scale for non-specific physical symptoms, SOM) were evaluated through the Research Diagnostic Criteria for TMD (RDC/TMD) Axis II psychosocial assessment; TMD diagnoses were based on the Axis I criteria. Results the majority of patients presented a low disability or no disability at all, with only a small portion of individuals showing a severely limiting, high disability pain-related impairment (4.3%). On the other hand, abnormal scores of depression and somatization were high, with almost half of the individuals having moderate-to-severe levels of depression and three-fourths presenting moderate-to-severe levels of somatization. The prevalence of high pain-related disability (GCPS grades III or IV), severe/moderate depression and somatization was 14.3%, 44% and 74.1% respectively. Gender differences in scores of SCL-DEP (p=0.031) and SCL-SOM (p=0.001) scales were signficant, with females presenting the highest percentage of abnormal values. Conclusion patients with TMD frequently present an emotional profile with low disability, high intensity pain-related impairment, and high to moderate levels of somatization and depression. Therefore, given the importance of psychosocial issues at the prognostic level, it is recommended that clinical trials on TMD treatment include an evaluation of patients' psychosocial profiles.

Évaluation de la prise en charge médicamenteuse de la douleur chronique

Introduction. Les douleurs chroniques sont fréquentes en oncologie et en rhumatologie. Elles constituent un problème de santé publique. Le traitement de la douleur comporte des thérapeutiques médicamenteuses et non médicamenteuses. L'objectif du travail était d'évaluer la prise en charge médicamenteuse des patients présentant une douleur chronique. Méthodologie. Il s'agit d'une étude longitudinale et prospective de cinq mois. Elle a été réalisée dans le service d'oncologie de l'Hôpital Général de Yaoundé et le service de rhumatologie de l'Hôpital Central de Yaoundé. Nous avons inclus tous les patients présentant un syndrome douloureux chronique et ayant donné leur consentement éclairé. Les variables étudiées étaient l'intensité de la douleur, les pathologies en cause, les protocoles antalgiques, les effets secondaires, l'observance et la satisfaction des patients. Résultats. Six cent six patients étaient recrutés avec une majorité féminine. Les pathologies les plus rencontrées en rhumatologie étaient : l'arthrose (71,2%), la hernie discale (20,1 %). En oncologie il s'agissait du cancer du sein (24,1%) et du cancer du col de l'utérus (13,8%). A la consultation initiale, l'intensité de la douleur était légère (1,5%), modérée (94,7%) et sévère (3,8%). Les antalgiques utilisés étaient dominés par le paracétamol (56,1%) et le tramadol (39,8%). Les coantalgiques utilisés étaient les antiépileptiques (43,1%) et les myorelaxants (34,5%). Au troisième rendez-vous, la douleur était légère (90,6%), l'observance au traitement était moyenne chez 426 patients (70,3%) et 97,2% des patients étaient satisfaits. Conclusion. La prise en charge de la douleur chronique est effective et adaptée. Elle fait appel aux antalgiques usuels. Les co-antalgiques occupent une place non négligeable

Caracterização da dor em pacientes com doença de Parkinson / Pain characterization of Parkinson's disease patients

FUNDAMENTO: A dor é um sintoma não motor frequente em indivíduos com doença de Parkinson (DP). Pode estar associada aos sinais motores ou surgir no início da doença. Os mecanismos subjacentes à dor na DP ainda não são bem elucidados e muitos fatores podem influenciá-la, como o uso de levodopa e a presença de outros sintomas não motores, como depressão. OBJETIVOS: Descrever a prevalência e caracterizar a dor em pacientes com DP de um centro terciário referência em pesquisa e assistência clínica. MÉTODOS: Foram recrutados pacientes com diagnóstico de DP idiopática a partir do ambulatório de neurologia do Centro de Especialidades Médicas (CEM) da Santa Casa de Belo Horizonte/MG. Um questionário para coleta de dados sociodemográficos e clínicos foi aplicado. A função cognitiva, gravidade dos sinais e sintomas, depressão, distúrbios de sono e fadiga foram avaliados. A dor foi mensurada por meio do Questionário de McGill e Escala Visual Numérica. RESULTADOS: Participaram do estudo 45 pacientes, sendo que 19 (42,2%) apresentavam queixa de dor e, em sua maioria, após o diagnóstico de DP (74%). Não houve diferença entre os grupos com dor e sem dor para os parâmetros clínicos avaliados, com exceção da fadiga que foi mais prevalente (p=0,036) e mais grave (p=0,031) nos pacientes com dor. CONCLUSÃO: A dor é um sintoma prevalente em pacientes com DP atendidos no CEM. A partir dos resultados obtidos pelo McGill, observou-se que a dor crônica e profunda, acometendo principalmente os membros inferiores, com importantes aspectos sensoriais e afetivos, foi comum nos pacientes avaliados.

BACKGROUND: Pain is a common non-motor symptom in Parkinson´s Disease (PD). It can be associated to motor signs or can arise in the beginning of the disease. Mechanisms of pain in PD are not completely understood. Moreover, many factors can interfere, such as use of levodopa and presence of other non-motor symptoms as depression. OBJECTIVES: The aim of this study was to describe prevalence and characterization of pain in PD patients from a research and clinical terciary care center in Belo Horizonte, Minas Gerais, Brazil. METHODS: PD patients from the Neurology Center of Santa Casa Hospital (Belo Horizonte, MG, Brazil) were recruted. Socio-demographic and clinical data were collected. Cognitive function, severity of PD signs and symptoms, depression, sleep disturbance and fatigue were evaluated. Pain was measured by McGill Pain Questionnaire and Visual Numeric Scale (VNS). RESULTS: Forty-five PD patients participated in the study and 42,2% had pain complaints, mostly (74%) after PD diagnosis. No difference between group with pain or without pain for clinical parameters was detected, except for fatigue, which was more prevalent (p=0,036) and more severe (p=0.031) in patients with pain. CONCLUSION: Pain was very prevalent in PD patients from CEM. Results obtained from McGill showed that chronic and deep pain, mostly in lower limbs, with important physical and affective features was very common in this sample of PD patients.

Evaluación gastrointestinal en los pacientes con fiebre mediterránea familiar con dolor abdominal crónico y tratados con colchicina: serie de casos / Gastrointestinal evaluation in colchicine-treated familial Mediterranean fever patients with chronic abdominal pain: Cases series

El objetivo de este estudio fue evaluar a los pacientes con fiebre mediterránea familiar (familial Mediterranean fever, FMF) y dolor abdominal crónico resistentes al tratamiento con colchicina. Se incluyó a 48 pacientes diagnosticados en nuestro consultorio de reumatología pediátrica que tenían dolor abdominal a pesar del tratamiento con colchicina. A todos los pacientes se los derivó a un gastroenterólogo pediátrico. Se registraron las características del dolor, tales como aparición, duración y frecuencia; se planificó una endoscopía digestiva para obtener un diagnóstico diferencial. Se determinó la presencia de una mutación del gen MEFV en 46 pacientes. La mediana de la duración del tratamiento fue de 2,8 años. Aproximadamente el 60% de los pacientes tenían dolor abdominal todos los días o de dos a tres veces a la semana; en el 73% de los casos, duró menos de tres horas. A 41 pacientes se les realizó una endoscopía digestiva alta. La gastroduodenitis es un hallazgo frecuente en los pacientes con FMF y dolor abdominal persistente a pesar del tratamiento. Los pacientes con los puntajes más altos de severidad de la enfermedad tenían inflamación digestiva grave.

The aim of the study to evaluate familial mediterranean fever (FMF) patients with chronic abdominal pain unresponsive to colchicine treatment. Forty-eight patients who diagnosed in our Pediatric Rheumatology clinics and suffering from abdominal pain despite colchicine treatment were include. All patients were referred to a pediatric gastroenterologist. The pain characteristics such as onset, duration and frequency were recorded; gastrointestinal (GI) endoscopy was planned for differential diagnosis. MEFV mutation was determined in 46 patients. The median duration of treatment was 2.8 years. Approximately 60% of the patients suffered from abdominal pain every day or 2-3 times a week, in 73% of the cases it lasted less than three hours. Forty-one patients underwent upper GI endoscopy. Gastroduodenitis is a common finding in persisting abdominal pain despite therapy of FMF patients. The patients with the highest disease severity scores had severe inflammation within the entire GI system.

Saúde, dor e atividades de vida diária entre idosos praticantes de Lian Gong e sedentários / Health, pain and daily activities among elderly people practicing Lian Gong and sedentary elderly people

Resumo A prática regular de atividade física entre idosos contribui tanto para a prevenção e a redução da dor, quanto atua na promoção do envelhecimento ativo. Diante disso, este estudo teve como objetivo avaliar a presença de dor crônica em idosos atendidos em uma unidade de atenção primária do interior do estado de São Paulo, comparando os praticantes da ginástica chinesa (Lian Gong) e os idosos sedentários. Participaram deste estudo 60 idosos, sendo 30 integrantes de um grupo de Lian Gong e 30 sedentários. A presença da dor foi avaliada pelo Questionário Nórdico de Sintomas Osteomusculares, adaptado e validado para a cultura brasileira. A presença da dor nos últimos sete dias foi maior (62,3%) no grupo de praticantes de Lian Gong, porém com menor impedimento para realização de atividades (55,5%) quando comparados com o grupo de sedentários. Nos indivíduos ativos a presença da dor na parte inferior das costas foi estatisticamente menor (p < 0,05) quando comparados ambos os grupos. A prática do Lian Gong esteve relacionada com a percepção positiva da própria saúde, o menor uso de medicamentos, a adoção de práticas de autonomia no próprio cuidado e a sensação de menor impedimento para realizar atividades de vida diária.

Abstract It is a well-known fact that the practice of physical activity on a regular basis among elderly people contributes to the prevention and reduction of pain, as well as promote active ageing. Based on this premise, the scope of this study was to evaluate the presence of chronic pain among elderly people attended in a primary health care unit in a city in the interior of Sao Paulo State, Brazil, by comparing those who practice Chinese gymnastics (Lian Gong) and the sedentary. Sixty elderly people were divided between 30 sedentary and 30 who participate in a group practicing Lian Gong. The presence of pain was assessed through the Nordic Questionnaire on Musculoskeletal Symptoms, already adapted and validated for Brazilian culture. When questioned about pain in the last seven days, the Lian Gong group showed a higher presence (62,3%) of pain when compared to the sedentary group, although they had fewer difficulties in performing daily activities (55,5%). Among the active elderly the presence of lower back pain was statistically inferior (p < 0.05) when comparing the groups. The practice of Lian Gong was associated to a more positive perception of one's health, less use of medicines, as well as the adopting of self-care practices and the feeling of fewer impairments in performing daily activities.

Dor lombar em adolescentes do semiárido: resultados de um censo populacional no município de Caracol (PI), Brasil / Low back pain among adolescents in the semiarid region: results of a population census in the city of Caracol, State of Piauí, Brazil

Resumo O objetivo deste artigo é avaliar a prevalência e os fatores associados à dor lombar nos últimos 12 meses entre adolescentes de um município do sul do estado do Piauí, Brasil. Estudo transversal com 1112 adolescentes de 13-19 anos do município de Caracol. Investigaram-se características demográficas, socioeconômicas, nutricionais, comportamentais e comorbidades. O desfecho foi a ocorrência de dor lombar (DL) nos últimos 12 meses. Foi calculada a prevalência do desfecho de acordo com as variáveis independentes. Entre os adolescentes com DL no último ano, foi calculada a proporção de indivíduos com dor lombar crônica. Para análise dos fatores associados, foi utilizada a regressão de Poisson bruta e ajustada para cálculo das razões de prevalência. A prevalência de dor lombar nos últimos 12 meses foi de 32,9%. De acordo com a análise ajustada, sexo feminino (RP = 1,75; IC95%:1,45-2,10), idade entre 18-19 anos (RP = 1,27; IC95%:1,01-1,62), maior renda (RP = 1,33; IC95%:1,06-1,67), estar trabalhando (RP 1,25 IC95%:1,02-1,53) e apresentar distúrbios psiquiátricos menores (RP 1,51 IC95%: 1,25-1,82) permaneceram associados à DL nos últimos 12 meses. Este estudo encontrou elevada prevalência de DL entre adolescentes de um município pequeno do semiárido nordestino.

Abstract The scope of this article is to assess low back pain prevalence and associated factors in the last 12 months among adolescents in a city in the south of the State of Piauí. It was a cross-sectional study which included 1,112 adolescents aged 13-19 in the city of Caracol, Piauí. Demographic, socio-economic, nutritional, behavioral and comorbidty characteristics were investigated. The outcome was the occurrence of low back pain (LBP) in the last 12 months. The outcome prevalence was calculated in accordance with independent variables. The proportion of individuals with chronic LBP was calculated among adolescents with LBP in the last 12 months. Crude and adjusted Poisson regression was used to estimate the prevalence ratio in the analysis of associated factors. The prevalence of LBP in the last 12 months was 32.9%. According to the adjusted analysis, being female (PR = 1.75; 95%CI:1.45-2.10), being aged 18-19 (PR = 1.27; 95%CI:1.01-1.62), having higher income (PR = 1.33; 95%CI:1.06-1.67), having a job (PR 1.25 95%CI:1.02-1.53) and having minor psychiatric disorders (PR 1.51 95%CI: 1.25-1.82) were associated with LBP in the last 12 months. This study found a high prevalence of LBP among adolescents in a poor city in the semiarid region of Northeast Brazil.

Pain and temporomandibular disorders in patients with eating disorders

Abstract Orofacial pain and temporomandibular dysfunction may cause chronic facial pain, which may interfere with the emotional state and food intake of patients with eating disorders (ED), such as anorexia nervosa (AN) and bulimia nervosa (BN). Sixty-four patients were assigned to four groups: Group A (AN - restricting subtype): 07; Group B (AN - purging subtype ): 19; Group C (BN): 16; and Group D (control): 22. Complaints of pain are more prevalent in individuals with eating disorders (p<0.004). There are differences between the presence of myofascial pain and the number of hospitalizations (p = 0.046) and the presence of sore throat (p=0.05). There was a higher prevalence of masticatory myofascial pain and complaints of pain in other parts of the body in ED patients; however, there was no difference between ED subgroups. There was no difference in the number of self-induced vomiting between ED patients with and without myofascial pain.
