Spinal Cord Electrical Stimulation for Refractory Angina Treatment

Cardiovascular disease (CVD) is the main cause of death worldwide, including in Brazil. Angina pectoris is a challenging disease because its clinical manifestation is not always related to the degree of obstruction. Visceral pain fromany source can be totally disabling. It influences all aspects of the life of a patient and it can be one of the main causes of absence from work and of family disruption. Spinal cord electrical stimulation (SCES) has been traditionally applied for the treatment of neuropathic pain, with good to excellent results. Visceral pain syndrome can be as debilitating and disabling as somatic or neuropathic pain; however, there seems to be a lack of consensus on the appropriate treatment and strategies for these disorders. Themajor difference of SCES for visceral pain, compared to postlaminectomy syndrome or to regional complex syndrome, is the number of stimulated dermatomes. In most viscera, the somatotopic arrangement has two to four medullar levels, sometimes requiring laterality. After reviewing the literature, we have concluded that SCES is now a viable, low-risk option with satisfactory results for the treatment of neuropathic and visceral pain; therefore, it can be used in refractory angina after the failure of standard therapy. However, further studies are required to increase the application and efficacy of this procedure in the clinical practice.

Ozonioterapia em lombociatalgia / Ozone therapy for lumbosciatic pain

JUSTIFICATIVA E OBJETIVOS: A maioria dos adultos sofre de vários episódios de lombalgia durante sua vida. A ozonioterapia é método minimamente invasivo, capaz de oferecer analgesia para a maioria dos pacientes, com raros relatos de complicações. O objetivo deste estudo foi revisar a literatura referente ao uso da ozonioterapia no tratamento de lombalgia e lombociatalgia. CONTEÚDO: Realizada busca na Biblioteca Virtual em Saúde utilizando as seguintes palavras-chaves: ozone, therapy, pain, back, lumbodynia. As fontes de busca incluíram: LILACS, Medline, Cochrane, Pubmed, Ibecs, e em revistas para trabalhos, sobre estudos publicados originalmente nas línguas inglesa, espanhola e portuguesa, nos últimos anos. Foram selecionados 54 artigos. Deles dois eram estudos multicêntricos aleatórios, quatro eram revisões sistemáticas, uma era metanálise com mais de 8.000 pacientes em múltiplos centros, um era consenso nacional italiano, vários trabalhos duplamente encobertos, alguns com grupo controle, e muitos observacionais. O grau de evidência para alicerçar uma recomendação mais vigorosa ainda é considerado baixo (II-3 para a administração intradiscal e II-1 para intramuscular paravertebral ou intraforaminal), porém, este panorama parece dinâmico e com tendência a favor da indicação da ozonioterapia. CONCLUSÃO: A ozonioterapia se mostrou eficaz no tratamento da lombalgia com ou sem ciatalgia, sendo associada a poucos eventos adversos.

BACKGROUND AND OBJECTIVES: Most adults have several low back pain episodes during their lives. Ozone therapy is a minimally invasive method able to promote analgesia for most patients, with few reports of complications. This study aimed at reviewing the literature on the use of ozone therapy to treat low back pain and lumbosciatic pain. CONTENTS: Virtual Health Library was searched using the following keywords: ozone, therapy, pain, back, lumbodynia. Search sources included: LILACS, Medline, Cochrane, Pubmed, Ibecs and scientific journals, looking for articles originally published in English, Spanish and Portuguese in recent years. Fifty-four articles were selected. Two were randomized multicenter studies, four were systematic reviews, one was a meta-analysis with more than 8 thousand patients from different centers, one was a national Italian consensus, many were double-blind studies, some had control groups and many were observational studies. The level of evidence to support a stronger recommendation is still low (II-3 for intradiscal administration and II-1 for paravertebral or intraforaminal muscular administration), however this scenario seems to be dynamic with a trend toward the indication of ozone therapy. CONCLUSION: Ozone therapy was effective to treat low back pain with our without sciatic pain, being associated to few adverse events.

Auto-eficácia e sintomas depressivos em doentes com dor crônica / Self-efficacy and depressive symptoms in chronic pain patients

CONTEXTO: Auto-eficácia é a crença na habilidade pessoal de desempenhar com sucesso tarefas ou de apresentar comportamentos para produzir um resultado desejável. É conceito-chave para o adequado controle de doenças crônicas e estudos sobre o tema são incipientes no Brasil. OBJETIVO: Avaliar a crença de auto-eficácia de pacientes com dor crônica e relacioná-la a variáveis sociodemográficas, de características da dor e à presença de sintomas depressivos. MÉTODOS: A amostra, de conveniência, foi de 132 sujeitos. Os instrumentos utilizados foram a Escala de Auto-Eficácia para Dor Crônica (AEDC) e o Inventário de Depressão de Beck (IDB). RESULTADOS: O escore médio de auto-eficácia foi 170,8 (DP = 56,7). Auto-eficácia menor foi observada nos pacientes com até 8 anos de escolaridade, quando comparada à de pacientes com escolaridade entre 9 e 11 anos (p = 0,015). Auto-eficácia mais elevada foi observada nos doentes com dor menos intensa (p = 0,042). A Escala AEDC apresentou correlação negativa com o IDB (r = - 0,48; p < 0,01). CONCLUSÕES: Os doentes com escolaridade de até 8 anos apresentaram auto-eficácia menor que os doentes que tinham entre 9 e 11 anos de escolaridade. Os pacientes com dor menos intensa e os doentes com menos sintomas depressivos apresentaram maior auto-eficácia.

BACKGROUND: Self-efficacy is the belief about oneÆs personal ability to perform a task or specific behavior successfully. Self-efficacy is a key concept to manage chronic diseases and the studies about it are insufficient in Brazil. OBJECTIVE: To evaluate chronic pain patientÆs self-efficacy belief and relate to social demographic variables, pain and depressive symptoms. METHODS: The convenience sample was 132 subjects. The instruments utilized were Chronic Pain Self-efficacy Scale (CPSS) in Portuguese version (AEDC) and Beck Depression Inventory (BDI). RESULTS: The self-efficacy average score was 170.8 (DP = 56.7). Low self-efficacy was observed in 8 year education level patients compared to 9 to 11 year education level (p = 0.015). Higher self-efficacy was observed in patients with lower pain intensity (p = 0.042). The AEDC was negative correlated to IDB depression (r = - 0.48; p < 0.01). CONCLUSIONS: Patients with 8 year education level showed low self-efficacy than patients with 9 to 11 year education level. Subjects with lower pain intensity and fewer depressive symptoms showed higher self-efficacy scores.
