ABSTRACT
Objective: Evaluate clinical outcome of dorsal root ganglia (DRG) pulsed radiofrequency (PRF) treatment in neuropathic pain of patients with radiculopathy regarding improvement of pain and degree of patients? satisfaction. Method: Forty-five procedures in cervical and lumbossacral spine. Data collected by phone call interviews (independent researcher). Evaluation done after one month and at minimum three months follow-up. Analyzed data included objective and subjective improvement, and degree of satisfaction. Results: Outcome much better in 31%, 36% better, 24% unchanged, 9% worse. At initial evaluation, relief was rated: 24% excellent, 16% good, 27% moderate, 33% poor. At late evaluation, 27% excellent, 18% good, 7% moderate, 49% poor. Degree of satisfaction was high (82% of patients reported they certainly or probably would repeat the procedure). Conclusion: PRF was effective and safe in selected patients. Most patients were satisfied and would repeat/recommend the procedure...
Objetivo: Avaliar a evolução clínica do tratamento com radiofrequência pulsada (RFP) de gânglio da raiz dorsal (GRD) na dor neuropática em pacientes com radiculopatia, considerando melhora da dor e grau de satisfação dos pacientes. Método: Quarenta e cinco procedimentos na coluna cervical e lombossacra. Os dados foram coletados por meio de entrevistas telefônicas (pesquisador independente). Avaliação inicial feita após um mês e final no mínimo de três meses de acompanhamento. Dados analisados incluíram melhora objetiva, subjetiva e o grau de satisfação. Resultados: Evolução ?muito melhor? em 31%, ?melhor? em 36%, ?inalterado? em 24%, ?pior? em 9%. Na avaliação inicial: 24% ?excelente?, 16% ?bom?, 27% ?moderada?, 33% ?pobre?. Na avaliação final, 27% ?excelente?, 18% ?bom?, 7% ?moderada?, 49% ?pobre?. O grau de satisfação foi elevado (82% dos pacientes relataram que certamente ou provavelmente repetiriam o procedimento). Conclusão: RFP foi eficaz e segura em pacientes selecionados. A maioria dos pacientes ficou satisfeita e repetiu/recomendou o procedimento...

153 SmEDTMP was obtained from enriched 153Sm irradiated at the 5 MW Chilean Research reactor and labelled at a molar ratio of 15:1 pH 7.5. Biodistribution, autoradiography, radiochemical purity tests were done for evaluation. 40 patients were treated with 37-55 MBq/kg weight. Bone scans using 99mTcHMDP were obtained prior and after treatment. Bone marrow depression was observed in 37 percent of them and normal liver function in all of them. In 45 percent the pain dissapear completely, in 22,5 percent significantly decreased and partially in 30 percent. In 17 patients more than one dosis was injected. Our preliminary results indicate that 153 SmEDTMP is a promising radiotherapeutic agent for palliative treatment of metastasic bone cancer pain and encourage its use specially because it can be produced in countries with low economic resources, thus a large number of patients can get the benefits of this new procedure
