Complex regional pain syndrome in the orofacial region. Case report / Síndrome complexa de dor regional em região orofacial. Relato de caso

ABSTRACT BACKGROUND AND OBJECTIVES: The complex regional pain syndrome is characterized by presenting autonomic, sensory and motor difficult to control changes of the chronic evolution. Its pathophysiology and treatment are not fully defined, and the search for an increasingly effective treatment is a subject of medical concern. The involvement of the orofacial region has an even rarer incidence, and the literature reports only 14 cases in five decades. The objective of this report was to warn physicians and researchers about the importance of a correct diagnosis and to show the possibility of controlling this dysfunction with conservative treatment. CASE REPORT: A 68-year-old female patient, who after a facial trauma and three subsequent surgical procedures, developed orofacial complex regional pain syndrome. Several therapeutic regimens were performed, and after the last one she became completely asymptomatic: oxcarbazepine (900mg/day), morphine-controlled liberation (120mg/day), fluoxetine (40mg/day) and clonazepam (2mg/day), electrotherapy and oral rehabilitation. CONCLUSION: The diagnosis criteria for complex regional pain syndrome recommended by the International Association for the Study of Pain, revised in 2007, should be followed. The treatment of this neuropathic syndrome includes anticonvulsants, tricyclics, opioids, electrotherapy and somatic and stellate ganglion block, the latter when the pain is maintained by the sympathetic nervous system. In this report of an orofacial complex regional pain syndrome II, pain control was shown without the need for sympathetic ganglion block, which can be a warning to the medical class to a correct diagnosis and an effective and less invasive treatment.

RESUMO JUSTIFICATIVA E OBJETIVOS: A síndrome complexa de dor regional se caracteriza por apresentar alterações autonômicas, sensitivas e motoras de evolução crônica de difícil controle. Sua fisiopatologia não está totalmente definida e a busca por um tratamento cada vez mais eficaz é objeto de preocupação médica. O comprometimento da região orofacial tem uma incidência ainda mais rara e a literatura relata apenas 14 casos em cinco décadas. O objetivo deste relato foi alertar médicos e pesquisadores para a importância de um diagnóstico correto e mostrar a possibilidade de controle dessa disfunção com o tratamento conservador. RELATO DO CASO: Paciente do sexo feminino, 68 anos, após trauma facial e três intervenções cirúrgicas posteriores, desenvolveu quadro de síndrome complexa de dor regional orofacial. Foram realizados vários esquemas terapêuticos, o último dos quais tornou-a completamente assintomática: oxcarbazepina (900mg/dia), morfina de liberação controlada (120mg/dia), fluoxetina (40mg/dia) e clonazepam (2mg/dia), eletroterapia e reabilitação oral. CONCLUSÃO: Os critérios de diagnóstico para a síndrome complexa de dor regional, preconizados pela International Association for the Study of Pain, revisados em 2007, devem ser seguidos. O tratamento desta síndrome neuropática inclui anticonvulsivantes, tricíclicos e opioides, eletroterapia, bloqueio somático e de gânglio estrelado, este último quando a dor for mantida pelo sistema nervoso simpático. Neste relato de uma síndrome complexa de dor regional II orofacial foi mostrado o controle da dor sem a necessidade de bloqueio do gânglio simpático, o que pode alertar a classe médica para um correto diagnóstico e um tratamento eficaz e menos invasivo.

Acupuncture as Adjuvant Therapy for Sleep Disorders in Parkinson's Disease.

There are few studies which attest the efficacy of acupuncture on treatment of sleep disturbs in Parkinson disease. The aimed of this randomized clinical trial was to evaluate the effects of acupuncture on sleep disturbs of 22 patients with diagnosis of idiopathic Parkinson disease (Hoehn-Yahr 1 to 3) who have assistance on the Pro-Parkinson Program of Clinical Hospital at Federal University of Pernambuco in Brazil. All participants were evaluated by Parkinson Disease Sleep Scale (PDSS) before and after 8 weeks. The experimental group was submitted to 8 sections (once a week) which had duration of 30 minutes. The control group had no intervention. The intervention was executed using the acupuncture points LR3 (Taichong), SP6 (Sanyinjiao), LI4 (Hegu), TE5 (Wai-Guan), HT7 (Shenmen), PC6 (Neiguan), LI11 (Quchi), GB20 (Fengchi). Paired analyses were obtained by Wilcoxon test and independent analyses were made according to Mann-Whitney test. This study presented a potential therapeutic benefit of acupuncture on sleep disturbs of Parkinson's disease patients. This study showed a possible therapeutic benefit through acupuncture in sleep disorders in patients with PD. However, we propose new studies related to the effects of acupuncture on the clinical symptoms and evolution of the disease.

Effects of acupuncture and electroacupuncture on estradiol-induced inflammation and oxidative stress in health rodents

PURPOSE:To investigate the effects of classical acupuncture (Ac) and electroacupuncture (EAc) on estradiol-induced inflammation and oxidative stress in health rodents. METHODS: Twenty-four eight-week old female rats were treated with estradiol valerate (EV) 4.0 mg i.m. single dose and randomly assigned to four groups (n=6): G1(control), G2 (Ac), G3 (EAc 2 Hz) and G4 (EAc 100 Hz). After 60 days all rats were anesthetized with chloral hydrate 10% (0.1 ml/30 g weight of the animal) and submitted to Ac/EAc for twenty minutes. The procedures were repeated on days three, five, seven and nine of the study. The equivalent of the human right ST-36 (Zusanli) and SP-6 (Sanyinjiao) acupoints were chosen for needling and electrical stimulation. On the 10th day of the experiment, all rats were anesthetized for collection of blood and tissues (ovaries) samples for biochemical analysis and histological examination. RESULTS:Glutathione (GSH) and malonaldehyde (MDA) concentrations increased significantly in all groups (plasma and ovary) while myeloperoxidase (MPO) activity decreased significantly in all groups compared with control group (G1). CONCLUSIONS:Both classical acupuncture and electroacupuncture decrease systemic and local oxidative stress and ovary inflammation in healthy rats exposed to estrogenic stimulation. EAc enhances lipid peroxidation at systemic and local levels in female rats exposed to estrogenic stimulation.(AU)
