Use of High-Resolution Ultrasound to Guide Alcohol Neurolysis for Chronic Pain.

BACKGROUND: The diagnosis and treatment of neuropathic pain is often clinically challenging, with many patients requiring treatments beyond oral medications. To improve our percutaneous treatments, we established a clinical pathway that utilized ultrasound (US) guidance for steroid injection and alcohol ablation for patients with painful neuropathy. OBJECTIVES: To describe a collaborative neuropathy treatment pathway developed by a neurosurgeon, pain physicians, and a sonologist, describing early clinical experiences and patient-reported outcomes. STUDY DESIGN: A retrospective case series was performed. METHODS: Patients that received percutaneous alcohol ablation with US guidance for neuropathy were identified through a retrospective review of a single provider's case log. Demographics and treatment information were collected from the electronic medical record. Patients were surveyed about their symptoms and treatment efficacy. Descriptive statistics were expressed as medians and the interquartile range ([IQR]; 25th and 75th data percentiles). Differences in the median follow-up pain scores were assessed using a Wilcoxon signed-rank test. RESULTS: Thirty-five patients underwent US-guided alcohol ablation, with the average patient receiving one treatment (range: 1 to 2), having a median duration of 4.8 months until reinjection (IQR: 2.9 to 13.1). The median number of steroid injections that individuals received before US-guided alcohol ablation was 2 (IQR: 1 to 3), and the median interval between steroid injections was 3.7 months (IQR: 2.0 to 9.6). Most (20/35 [57%]) patients responded to the survey, and the median pain scores decreased by 3 units (median: -3, IQR: -6 to 0; P < 0.001) one week following the alcohol ablation. This pain reduction remained significant at one month (P < 0.001) and one year (P = 0.002) following ablation. Most (12/20 [60%]) patients reported that alcohol ablation was more effective in improving their pain than oral pain medications. LIMITATIONS: Given the small sample size, treatment efficacy for alcohol neurolysis cannot be generalized to the broader population. CONCLUSIONS: US-guided percutaneous treatments for neuropathic pain present a growing opportunity for interprofessional collaboration between neurosurgery, clinicians who treat chronic pain, and sonologists. US can provide valuable diagnostic information and guide accurate percutaneous treatments in skilled hands. Further studies are warranted to determine whether a US-guided treatment pathway can prevent unnecessary open surgical management.

The impact of tinnitus on the quality of life in patients with temporomandibular dysfunction.

INTRODUCTION: The most common otological symptoms in patients with temporomandibular disorders (TMD) are ear fullness, tinnitus and ear pain. OBJECTIVE: To evaluate the impact of tinnitus on the quality of life for patients with TMD. METHOD: This is a quantitative, cross-sectional retrospective study. The sample consisted of 19 individuals with TMD, 17 (89.47%) females and 2 (10.53%) male, mean age 53.5 years. Data collection consisted of: anamnesis, pure tone audiometry, acuphenometry and application of the Portuguese version of the Tinnitus Handicap Inventory (Brazilian THI). RESULTS: 63.12% had had tinnitus for less than five years, and 15.79% had tinnitus that sounded like whistling, rain and/or a cricket. There was a predominance of laterality in the right ear (42.11%). 52.63% of the subjects reported that their tinnitus is continuous, while 31.58% stated that it lasts for days, and 47.37% report that it is common. The audiometry revealed mean audiometric thresholds above 25 dB HL in the high frequencies (3000, 4000, 6000 and 8000 Hz) bilaterally. In acuphenometry, the average loudness of the tinnitus was 21 dB SL the right ear and 17.85 dB SL in the left ear, and the average tinnitus pitch was 3775 Hz in the right ear and 3750 Hz in the left ear. The total THI score was 37.8 points. It appears that there is significant correlation between the THI scale, time of tinnitus duration and its occurrence. CONCLUSION: Tinnitus reported in patients with TMD caused moderate impact on quality of life and can be seen in the presence of background noise although daily activities can still be performed.

Musculoskeletal pain perception and hypertension / Percepção de dor musculoesquelética e hipertensão arterial

BACKGROUND AND OBJECTIVES: Several human studies have shown an inverse relation between pain perception and blood pressure. This study aimed at investigating the association between musculoskeletal pain report and hypertension in a group of workers. METHODS: Using a body diagram with image and intensity scale (1 to 10), 349 workers (243 males and 106 females) were asked about the presence and sensitivity to musculoskeletal pain. All were submitted to blood pressure measurement and diagnosis of hypertension by the occupational physician. RESULTS: One hundred workers (28.7%) have reported some type of musculoskeletal pain and from these 12 were hypertensive and 88 normotensive. There has been no difference in musculoskeletal pain prevalence and sensitivity between hypertensive and normotensive workers. Notwithstanding the lack of significant difference, in average hypertensive workers had higher prevalence (38.7% vs 27.7%) and sensitivity to pain as compared to normotensive workers (2.3±0.8 vs 2.1±0.9, respectively). CONCLUSION: It was not possible to confirm in the group of studied workers literature evidences that hypertensive individuals have lower pain prevalence and sensitivity as compared to normotensive individuals. .

JUSTIFICATIVA E OBJETIVOS: Diversos estudos em humanos têm demonstrado relação inversa entre percepção de dor e pressão arterial. O objetivo do estudo foi investigar a associação entre o relato de dor musculoesquelética e hipertensão arterial em um grupo de trabalhadores. MÉTODOS: Utilizando-se um diagrama corporal com imagem e escala para intensidade (1 a 10), 349 trabalhadores (243 homens e 106 mulheres) foram questionados a respeito da presença e sensibilidade à dor musculoesquelética. Todos foram submetidos a medidas de pressão arterial e diagnóstico de hipertensão arterial pelo médico do trabalho. RESULTADOS: Cem trabalhadores (28,7%) relataram algum tipo de dor musculoesquelética e destes 12 eram hipertensos e 88 normotensos. Não houve diferença nem na prevalência nem na sensibilidade da dor musculoesquelética entre trabalhadores hipertensos e normotensos. Apesar da ausência de diferença significativa, em média os hipertensos demonstraram maior prevalência (38,7% vs 27,7%) e sensibilidade à dor do que os normotensos (2,3±0,8 vs 2,1±0,9, respectivamente). CONCLUSÃO: Não foi possível confirmar no grupo de trabalhadores estudados as evidências da literatura de que indivíduos hipertensos possuem menor prevalência e sensibilidade à dor do que normotensos. .

Clinical topographic analysis of neuropathic pain in patients admitted in a center of multidisciplinary treatment / Análise clínico-topográfica da dor neuropática de pacientes admitidos em um centro de tratamento multidisciplinar

BACKGROUND AND OBJECTIVES: Verbal investigation is a critical step of nursing neurological evaluation of neuropathic pain patients, due to its multidimensionality. There are few studies in the literature specifically dealing with this subject. In light of the above, this study aimed at evaluating medical records on clinical topographic characteristics of neuropathic pain reported by patients from a multidisciplinary management center. METHODS: This is a documental, crossover and quantitative study evaluating 50 medical records of patients with established neuropathic pain diagnosis who came for routine consultations between January and June 2014. Data collection form was based on McGill Pain Questionnaire and data regarding age, gender, pain topography and presence of verbal descriptors were analyzed. Data were submitted to statistical analysis and Chi-square test was applied to compare association among variables. RESULTS: There has been prevalence of females (64%), with mean age of 57 years. Most common pain descriptors were from the sensory dimension and were associated to cases where neuropathy affected lower limbs (p=0.006). CONCLUSION: There has been association between topography and pain dimension. Due to the subjectivity and complexity involving neuropathic pain evaluation, it is necessary to understand its clinical manifestations and to prepare the whole multidisciplinary team, especially Nursing, which plays a critical role in verbal investigation of painful patients. .

JUSTIFICATIVA E OBJETIVOS: A investigação verbal é uma etapa fundamental do exame neurológico do enfermeiro na avaliação do paciente com dor neuropática, dada à sua multidimensionalidade. Na literatura, poucos são os trabalhos que lidam especificamente com esse tema. Diante disso, o objetivo deste estudo foi analisar registros em prontuários sobre as características clínico-topográficas da dor neuropática relatadas por pacientes de um centro de tratamento multidisciplinar. MÉTODOS: Estudo documental, transversal, de natureza quantitativa. Analisaram-se 50 prontuários de pacientes com diagnóstico estabelecido de dor neuropática que compareceram para consultas de rotina entre janeiro e junho de 2014. Utilizou- -se formulário para coleta de dados baseado no Questionário de Dor McGill e foram analisados dados referentes a idade, gênero, topografia da dor e presença de descritores verbais. Os dados foram submetidos a análise estatística e aplicou-se teste de Qui- -quadrado para comparar a associação entre as variáveis. RESULTADOS: Prevaleceram pacientes do gênero feminino (64%), com média de 57 anos. Os descritores de dor mais citados foram da dimensão sensorial e se associaram aos casos em que a neuropatia atingia os membros inferiores (p=0,006). CONCLUSÃO:: Foi observada uma associação entre topografia e dimensão da dor. Em virtude da subjetividade e complexidade que envolvem a avaliação da dor neuropática, faz-se necessário o conhecimento das suas manifestações clínicas e o preparo de toda a equipe multidisciplinar, sobretudo da Enfermagem, que desempenha papel fundamental na condução da investigação verbal do paciente com dor. .

Paracetamol e dipirona por via endovenosa aplicados à analgesia pós-operatória de pacientes pediátricos submetidos à amigdelectomia em hospital-dia: um estudo prospectivo, randomizado, duplo-cego, placebo controlado / Intravenous paracetamol and dipyrone for postoperative analgesia after day-case tonsillectomy in children: a prospective, randomized, double blind, placebo controlled study

O manejo da dor pós-amigdelectomia pode ser feito com uma série de medicamentos. OBJETIVO: O presente estudo duplo-cego placebo controlado pretendeu avaliar a eficácia de paracetamol e dipirona administrados por via endovenosa na analgesia de pacientes pediátricos pós-amigdelectomia. MÉTODO: Cento e vinte crianças com idades entre três e seis anos submetidas à amigdelectomia com ou sem adenoidectomia e/ou entubação foram randomizadas para receber infusões de paracetamol (15 mg/kg), dipirona (15 mg/kg) ou placebo (0,9% NaCl) durante a cirurgia. As avaliações foram executadas com 0,25, 0,50, 1, 2, 4, 6h de pós-operatório. Petidina 0,25 mg/kg foi utilizada como analgésico de resgate. Dose acumulada de petidina foi o desfecho primário. Medições de intensidade da dor, alívio da dor, nível de sedação, náusea e vômitos, hemorragia no pós-operatório e outros efeitos adversos foram anotados. RESULTADOS: Nenhuma diferença significativa foi encontrada na dose acumulada de petidina entre os grupos paracetamol e dipirona. A dose acumulada de petidina foi significativamente menor nos grupos paracetamol e dipirona em comparação ao grupo placebo. Nenhuma diferença significativa foi observada entre os escores de dor no pós-operatório dos grupos durante o estudo. CONCLUSÃO: Paracetamol endovenoso tem eficácia analgésica semelhante à da dipirona endovenosa; ambos ajudam a reduzir a necessidade de opioides na analgesia pós-operatória de pacientes pediátricos submetidos à amigdelectomia em hospital-dia.

Tonsillectomy is associated with severe postoperative pain for which, several drugs are employed for management. OBJECTIVE: In this double-blind, placebo-controlled study we aimed to evaluate the efficacy of intravenous paracetamol and dipyrone when used for post-tonsillectomy analgesia in children. METHOD: 120 children aged 3-6 yr, undergoing tonsillectomy with or without adenoidectomy and/or ventilation tube insertion were randomized to receive intraoperative infusions of paracetamol (15 mg/kg), dipyrone (15 mg/kg) or placebo (0.9% NaCl). Evaluation was carried out at 0.25, 0.50, 1, 2, 4, 6h postoperatively. Pethidine 0.25 mg/kg was utilized as rescue analgesic. Cumulative pethidine requirement was the primary outcome. Pain intensity measurement, pain relief, sedation level, nausea and vomiting, postoperative bleeding and any other adverse effects were noted. RESULTS: No significant difference was found in pethidine requirement between paracetamol and dipyrone groups. Cumulative pethidine requirement was significantly less in paracetamol and dipyrone groups vs. placebo. No significant difference was observed between groups in postoperative pain intensity scores throughout the study. CONCLUSION: Intravenous paracetamol is found to have a similar analgesic efficacy as intravenous dipyrone and they both help to reduce the opioid requirement for postoperative analgesia in pediatric day-case tonsillectomy.

Uso de questionários para avaliar a multidimensionalidade e a qualidade de vida do fibromiálgico / Using questionnaires to assess the quality of life and multidimensionality of fibromyalgia patients

A síndrome fibromiálgica (SFM) é uma síndrome dolorosa, de etiologia desconhecida, com alta prevalência e frequentes condições associadas, que causa grande impacto no cotidiano e na qualidade de vida dos pacientes. OBJETIVO: Verificar, devido ao seu caráter multifatorial, o poder discriminativo dos instrumentos, a fim de identificar indicadores que permitam expressar a autoavaliação e o autoconhecimento. PACIENTES E MÉTODOS: Trata-se de um estudo descritivo, exploratório, comparativo, de corte transversal e amostra de um grupo-teste (T), com diagnóstico de SFM (n = 63), e de um grupo-controle (C) submetido a interconsulta na Clínica da Dor (n = 75). Os instrumentos utilizados foram: Questionário de Impacto de Fibromialgia (FIQ), Escala Visual Analógica (EVA), Questionário de Dor McGill e o Protocolo Pós-Sono (PSI). Para avaliar a qualidade de vida, foi utilizado Questionário SF-12. RESULTADOS: Na amostra dos dois grupos houve predomínio do gênero feminino, média de idade de 42,3 ± 4,3 anos, 45 por cento casados e média de escolaridade de 8 ± 3,5 anos. Foi relatado um tempo médio de dor de 3,2 anos e uma média de dois anos para o diagnóstico de SFM no grupo T. O grupo T apresentou níveis mais altos de dor, ansiedade e depressão, pior qualidade de sono, menos flexibilidade e pior qualidade de vida, embora alguns desses sintomas também estejam presentes entre os indivíduos do grupo C. CONCLUSÃO: Todos os instrumentos têm poder discriminativo (P < 0,05), destacando FIQ, EAV e PSI, que produziram maior área sob a curva (AUC) ROC.

Fibromyalgia syndrome (FMS) is a painful condition of unknown etiology, highly prevalent, and associated with other conditions, which causes great impact on daily life and quality of life. OBJECTIVE: To assess, due to the multifactorial character of the FMS, the discriminating power of instruments used to identify good indicators of self-assessment and self-knowledge. PATIENTS AND METHODS: This is a descriptive, exploratory, comparative, cross-sectional study with quantitative approach, and sample comprising a treatment group (T), diagnosed with FMS (n = 63) and a control group (C), undergoing interconsultation at the Pain Outpatient Clinic (n = 75). The following instruments were used: Fibromyalgia Impact Questionnaire (FIQ); visual analogue scale (VAS); McGill Pain Questionnaire; and the Post-Sleep Inventory (PSI). To evaluate the quality of life, Medical Outcomes Study 12-item Short-Form Health Survey (SF-12) was used. RESULTS: In the two groups, female gender predominated. The mean age of the sample was 42.3 ± 4.3 years, 45 percent were married, and the average schooling was 8 ± 3.5 years. The mean duration of pain was 3.2 years, and a mean time of two years were required for the clinical diagnosis of FMS in group T. Group T had higher levels of pain, anxiety, and depression, worse quality of sleep, less flexibility, and worse quality of life, although some of these symptoms were also present in group C. CONCLUSIONS: All instruments had good discriminating power (P < 0.05), especially FIQ, VAS and PSI, whose areas under the ROC curve were greater.

Características clínicas de los pacientes que consultan a la Clínica de Dolor Crónico del Hospital Militar Central: histórico de 20 años / Clinical characteristics of patients consulting Chronic Pain Clinic of Hospital Militar Central, 20-year history / Características clínicas dos pacientes que consultam á Clínica de Dor Crônica de Hospital Militar Central, 20 anos de história

En este estudio se pretende identificar el perfil demográfico de los pacientes que acuden a la clínica del dolor del Hospital Militar Central que consultan por dolor crónico no maligno, a quienes se les ha valorado de manera integral y multidisciplinaria. Se revisaron los expedientes clínicos de los pacientes atendidos en la clínica de dolor del Hospital Militar Central (HMC) entre abril de 1989 y abril de 2009. Un total de 291 pacientes se tomaron de manera aleatoria simple como muestra representativa para un intervalo de confianza del 95%. Se utilizó un cuestionario que incluyó 26 descriptores que evaluaron datos demográficos, epidemiológicos, respuesta emocional y afectación en áreas de ajuste por la presencia de dolor crónico en estos pacientes. Se encontraron múltiples datos estadísticos, como relevante se halló un perfil de pacientes relacionados con las fuerzas militares en un 90% (nivel de confianza 95%, IC 86-93) entre funcionarios militares, no militares y sus beneficiarios. El 49,4% son militares (nivel de confianza 95%, IC 43-55%). Prevalece como entidad más importante el dolor lumbar crónico 41,2% (nivel de confianza 95%, IC 35-47%) y el relacionado a miembros superiores e inferiores 11,6% (nivel de confianza 95%, IC 7,8 - 15%). Los diagnósticos más comunes en salud mental dados por psicología o psiquiatría fueron el trastorno de adaptación en el 59% de los casos (nivel de confianza 95%, IC 53-64,9%) y el trastorno de depresión en un 18% (Nivel de confianza 95%, IC 14-22,8%). Se encontró un 81% de compromiso en el área laboral en pacientes menores de 65 años (nivel de confianza 95%, IC 76-86%) por causa del dolor crónico y un 86,3 % (nivel de confianza 95%, IC 80-92%) entre aquellos con edades entre los 15 y los 30 años. En conclusión, el dolor crónico como enfermedad de alto costo en la población general, es un factor importante de incapacidad o inhabilidad laboral en los pacientes que consultan a la clínica de dolor del HMC, faltan estudios para definir si la población militar es más susceptible comparada con la población no militar...

This study aims to identify the demographic profile of patients who come to the Chronic Pain Clinic of the Hospital Militar Central to consult regarding chronic nonmalignant pain, who have been evaluated in an integral and multidisciplinary way. The medical records of the patients assisted in the Chronic Pain Clinic of the Hospital Militar Central (HMC) between April 1989 and April 2009. A total of 291 patients were randomly selected as a representative sample for a trust interval of 95%. A survey questionnaire was used, which included 26 descriptors evaluating demographic and epidemiological data, and emotional response and affectation in adjustment areas due to the presence of chronic pain in these patients. Multiple statistical data were found. A relevant datum was to find a profile of patients related to the military forces by 90% (95% significance level, CI 86-93%) among military and non-military officers and their beneficiaries. 49.4% are military personnel (95% significance level, CI 43-55% ). Chronic lumbar pain stands out as the most prevalent item - 41.2% (95% significance level, CI 35-47%), and the one related to upper or lower limbs, 11.6% (95% significance level, CI 7.8-15%). Most common diagnoses in mental health provided by the psychology and psychiatry sections were adjustment disorders in 59% of the cases (95% significance level, CI 53-64.9%), and depression disorder at 18% (95% significance level, CI 14-22.8%). An 81% commitment degree was found in the work force in patients aged less than 65 (95% significance level, CI 76.65%) due to chronic pain, and 86.3% (0.5% significance level, CI 80-92%) among those from 15 to 30 years old. To conclude, chronic pain as a high-cost disorder in the general population is an important factor in labor absence leaves or inability among patients consulting at the Chronic Pain Clinic of the HMC. There is a lack of studies to define whether the military population is more susceptible in comparison with the non-military population...
