Research has shown that individual members of traditional support groups gain a sense of identity and community and feelings of respect and support. Online support groups provide individuals avenues to find medical information and thus learn more about a given condition or illness. Little has been studied about the learning and instruction that occurs in online social support groups, especially in groups about chronic pain. The purpose of this qualitative case study was to explore the perceptions and experiences of members who participated in one open social support group. Siemen's constructivism theory served as the basis for comprehending the learning and instruction that took place in this group, and the research questions focused on the support group members' perceptions of this learning and instruction. Data were collected from 10 individuals who participated in a Facebook Reflex Sympathetic Dystrophy support group. Yin's case study framework provided additional support data analysis. Data were collected through individual, semistructured telephone interviews and observations of online discussions. A combination of open and axial coding was used to support content analysis. Themes identified were learning, knowledge, persuasion, and acceptance of underlying negativity. Online social support group participation involved shared experiences that facilitated learning and instruction; these findings could influence the structures of other support groups. Positive social change occurs when individuals are knowledgeable and well educated about social support groups because it is in these groups that trends, issues, and new information are learned. Informal learning occurs with the increased digital skills, especially within a person's virtual support networks

Introdução e objetivos: Estudos recentes sugerem que a estimulação magnética transcraniana repetitiva (EMTr) aplicada sobre o córtex motor é eficaz no tratamento analgésico de doentes com dor crônica. O objetivo deste estudo foi avaliar os efeitos da aplicação da EMTr sobre o córtex motor, utilizada como co-intervenção terapêutica no tratamento de pacientes com síndrome complexa de dor regional (SCDR) refratária aos tratamentos convencionais. Métodos: Vinte e três doentes com SCDR na mão foram distribuídos aleatoriamente em dois grupos de tratamentos para receberem o tratamento padrão (analgésicos, medicações adjuvantes e terapia física) associado a dez sessões diárias e consecutivas de EMTr rápida ou estimulação magnética placebo (EMTp), aplicadas sobre a região correspondente ao córtex motor da mão acometida. Os grupos foram comparados em relação aos aspectos epidemiológicos, apresentação clínica da doença, intensidade da dor, alterações do humor, qualidade de vida e função do membro acometido até noventa dias após a conclusão do tratamento, utilizando-se de entrevistas estruturadas, da escala visual analógicas de dor (EVA), do questionário de dor de McGuill (QM), do questionário PIQ-6 (Pain Inpact Questionnaire), do questionário DASH (Disabilities of Arm, Shoulder and Hand), do questionário SF-36 e dos questionários Hamilton para ansiedade e depressão. Resultados: Ocorreu redução significativa dos escores da EVA no grupo tratado com EMTr durante o tratamento, que durou até o sétimo dia após o encerramento das aplicações (p<0.05). A redução média da EVA no grupo tratado com EMTr foi de 4.65 cm (redução de 50.9% dos escores de dor), estatisticamente superior ao grupo tratado com placebo, no qual a redução foi de 2.18 cm (redução de 24.7%). A diminuição dos escores de dor na EVA foi independente de outras variáveis em estudo, exceto pela melhora no domínio sete do questionário SF-36 (aspectos emocionais). Conclusões: A aplicação de EMTr rápida sobre a área motora da mão de doentes com SCDR, associada a um programa de tratamento padrão, resulta em diminuição maior da percepção espontânea da dor quando comparada ao efeito do tratamento padrão isolado, independentemente de outros possíveis efeitos da EMTr sobre o humor, função do membro acometido ou qualidade de vida / Background and aims: There are many evidences that repetitive transcranial magnetic stimulation (r-TMS) of the motor cortex is effective in relief of chronic pain. The aim of this study was to evaluate the analgesic effects of r-TMS in patients with refractory CRPS. Methods: Twenty-three patients presenting with complex regional pain syndrome (CRPS) of the hand were randomly selected and treated with conventional treatment (analgesics, adjuvant medications and physical therapy) plus sham-TMS or r-TMS to the motor cortex opposite the affected limb: 100% MT, 10 hz, 10 s trains, 25 trains daily, 10 daily sessions. The Visual Analogical Scale of Pain (VAS), McGill Questionnaire, Pain Impact Questionnaire (PIQ-6), Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH), Hamilton Depression and Anxiety Rating Scales and SF-36 Questionnaire were the instruments used for the evaluation. The groups were comparable with regards to socio-demographics, mood and pain intensity. Evaluations were performed before, during TMS treatment and up to three months the end of the treatment. Results: There was a significant reduction in VAS scores favoring the r-TMS group up to the seventh follow-up day (p <0.05). The mean reduction in the rTMS group was of 4.65 cm (fall of 50.9%) against 2.18 cm (fall of 24.7%) in sham group during treatment. Improvement in VAS scores was independent of other variables, except for improvement in emotional aspects in the SF-36. Conclusions: During r-TMS sessions there was significant and positive improvement in pain experience of CRPS patients regardless of mood, function or quality of life effects

Topical exposure to isopropyl alcohol has been reported in the literature to be toxic if sufficient isopropyl alcohol is absorbed (1-5). A clinical case is reported where a 48-y-old female presented with multiple unexplained cardiac and neurological deficits. The woman had developed the deficits over a 6-mo period in which she had been soaking towels with isopropyl alcohol and applying then to her skin overnight to ease arm pain she was experiencing. Cessation of the isopropyl alcohol exposure resolved her deficits within 3 d. A controlled repeat dermal exposure to isopropyl alcohol under clinical observation reproduced the deficits noted with corresponding serum and urine concentrations of isopropyl alcohol and acetone. Cessation of topical isopropyl alcohol exposure lead to subsequent resolution of all toxicities.
