1/252. A case of reflex sympathetic dystrophy (complex regional pain syndrome, type I) resolved by cerebral contusion.We present a case of refractory reflex sympathetic dystrophy (RSD) (complex regional pain syndrome, type I) whose symptoms (ongoing pain, allodynia, hyperhydrosis and temperature abnormalities) were resolved after the patient suffered a traumatic cerebral contusion in the left temporal lobe, which caused no neurological deficit. This case suggests that symptoms of some RSD patients may largely sustained by a complex network involving the brain.- - - - - - - - - - ranking = 1keywords = dystrophy (Clic here for more details about this article) |
2/252. sympathetic nervous system and pain: a clinical reappraisal.The target article discusses various aspects of the relationship between the sympathetic system and pain. To this end, the patients under study are divided into three groups. In the first group, called "reflex sympathetic dystrophy" (RSD), the syndrome can be characterized by a triad of autonomic, motor, and sensory symptoms, which occur in a distally generalized distribution. The pain is typically felt deeply and diffusely, has an orthostatic component, and is suppressed by the ischemia test. Under those circumstances, the pain is likely to respond to sympatholytic interventions. In a second group, called "sympathetically maintained pain" (SMP) syndrome, the principal symptoms are spontaneous pain, which is felt superficially and has no orthostatic component, and allodynia. These symptoms, typically confined to the zone of a lesioned nerve, may also be relieved by sympathetic blocks. Since the characteristics of the pain differ between RSD and SMP, the underlying kind of sympathetic-sensory coupling may also vary between these cases. A very small third group of patients exhibits symptoms of both RSD and SMP. The dependence or independence of pain on sympathetic function reported in most published studies seems to be questionable because the degree of technical success of the block remains uncertain. Therefore, pain should not be reported as sympathetic function independent until the criteria for a complete sympathetic block have been established and satisfied.- - - - - - - - - - ranking = 0.2keywords = dystrophy (Clic here for more details about this article) |
3/252. Autonomic regulation of lymphatic flow in the lower extremity demonstrated on lymphoscintigraphy in patients with reflex sympathetic dystrophy.PURPOSE: nuclear medicine techniques were used to show that the peripheral lymphatics are under autonomic control in much the same way as the blood vessels that supply the same anatomic region. methods: Three patients with complex regional pain syndrome type 1 (reflex sympathetic dystrophy) involving a lower extremity were evaluated using three-phase bone scintigraphy and peripheral lymphoscintigraphy. Each patient was treated with ipsilateral chemical lumbar sympathectomy, and lymphoscintigraphy was repeated within several days of the procedure. RESULTS: All three patients had evidence of decreased flow (compared with the contralateral extremity) to normal flow after ipsilateral sympathectomy. Bone scintigraphy, before and after sympathectomy, was difficult to interpret because of the effects of altered weight bearing. Two patients who had unilateral peripheral edema showed marked improvement after sympathectomy and increased lymphatic flow. CONCLUSIONS: Peripheral lymphatic function is controlled by the autonomic nervous system. In reflex sympathetic dystrophy, peripheral edema may be caused by an increased sympathetic stimulus to the lymphatics. Further study of this phenomenon may show that nuclear medicine studies, such as bone scintigraphy and lymphoscintigraphy, can be used to distinguish patients who will benefit from sympathectomy from those who will not, thereby obviating invasive testing and unnecessary invasive treatment.- - - - - - - - - - ranking = 1.2keywords = dystrophy (Clic here for more details about this article) |
4/252. reflex sympathetic dystrophy in children.reflex sympathetic dystrophy is a syndrome characterized by pain in one or more extremities, usually associated with vasomotor changes. Its occurrence in childhood has long been thought to be rare. We describe six cases of pediatric reflex sympathetic dystrophy and suggest that this syndrome could be underdiagnosed in children and adolescents. Psychologic problems frequently play a role in this disorder, which often can be treated conservatively. We also point out that the diagnosis is mainly clinical. An early diagnosis can avoid unnecessary tests and potentially can improve response to treatment, and prognosis.- - - - - - - - - - ranking = 1.2keywords = dystrophy (Clic here for more details about this article) |
5/252. syringomyelia and complex regional pain syndrome as complications of multiple sclerosis.OBJECTIVE: To describe a patient from Southeast asia with the optic-spinal phenotype of multiple sclerosis who developed syringomyelia and resultant complex regional pain syndrome (formerly named reflex sympathetic dystrophy). DESIGN: Case report. SETTING: Department of neurology at a tertiary care hospital in the Republic of singapore. PATIENT: A 53-year-old Chinese woman with a history of optic neuritis developed an episode of left hemiparesis leading to a diagnosis of multiple sclerosis. Serial neuroimaging studies revealed an active demyelinating plaque in the cervical area that later progressed into a syrinx. Over a period of 1 year she also developed signs of sympathetic dysfunction including horner syndrome of the left eye and complex regional pain syndrome in the left hand. CONCLUSIONS: A case of the optic-spinal phenotype of multiple sclerosis that is commonly observed in Southeast asia is described. This characteristically tissue-destructive form of multiple sclerosis resulted in syringomyelia complicated by a complex regional pain syndrome. Possible pathogenic mechanisms for these associations are discussed.- - - - - - - - - - ranking = 0.2keywords = dystrophy (Clic here for more details about this article) |
6/252. reflex sympathetic dystrophy in pregnancy: nine cases and a review of the literature.OBJECTIVE: To better understand the diagnosis of reflex sympathetic dystrophy of the lower extremities in pregnant women. SUBJECT: disease analysis using a retrospective series of nine cases and a review of the literature (57 patients and 159 sites of reflex sympathetic dystrophy). RESULTS: This disorder should be considered in any painful pelvic girdle syndrome or lower extremity pain. The hip is involved in 88% of cases. Symptoms develop in the third trimester of pregnancy, between the 26th and the 34th weeks. magnetic resonance imaging (MRI) provides an early, accurate, and very specific diagnosis, although standard radiography continues to be the first-line diagnostic tool. Fracture occurs in 19% of patients. The etiology and pathophysiology remain unclear, although pregnancy itself appears to play a significant role in this disease. Although locoregional mechanical factors partly explain reflex sympathetic dystrophy. hypertriglyceridemia appears to be a risk factor. This disorder develops independently, but the conclusion of pregnancy appears to be necessary for cure. reflex sympathetic dystrophy does not appear to affect the course of the pregnancy. Indications for cesarean delivery remain obstetrical and should be discussed when a fracture is involved. Simple therapeutic management using gentle physical therapy provides rapid and complete recovery in 2-3 months. CONCLUSION: reflex sympathetic dystrophy during pregnancy remains poorly understood and underestimated. Only joints of the inferior limbs are involved. MRI appears to be the best diagnostic tool. Pathogenesis remains unclear. Fractures are not rare. Treatment should be non-aggressive.- - - - - - - - - - ranking = 1.8keywords = dystrophy (Clic here for more details about this article) |
7/252. reflex sympathetic dystrophy in a patient with the antiphospholipid syndrome.We describe a 50-year-old woman who developed severe pain of the left lower limb after an episode of thrombophlebitis. Bone scintigraphy and thermography showed results indicative of reflex sympathetic dystrophy. Laboratory analysis revealed the presence of the lupus anticoagulant. The patient was diagnosed as antiphospholipid syndrome complicated with reflex sympathetic dystrophy of the left lower limb. To our knowledge, this is the first report of a patient with reflex sympathetic dystrophy with underlying antiphospholipid syndrome.- - - - - - - - - - ranking = 1.4keywords = dystrophy (Clic here for more details about this article) |
8/252. Complex regional pain syndrome type-1: a rare complication of arteriovenous graft placement.Complex regional pain syndrome (CRPS) type-1 (previously termed reflex sympathetic dystrophy syndrome) may be manifested as sympathetically mediated pain and swelling in an extremity. Among the numerous causes of reflex sympathetic dystrophy, the most common is trauma. We describe a 71-year-old diabetic man with endstage renal disease who presented with CRPS type-1 of the left hand one month after construction of a PTFE (polytetrafluroethylene) arteriovenous graft. The symptoms of CRPS improved greatly with stellate ganglion blocks and physical therapy.- - - - - - - - - - ranking = 0.4keywords = dystrophy (Clic here for more details about this article) |
9/252. reflex sympathetic dystrophy associated with amyotrophic lateral sclerosis.reflex sympathetic dystrophy (RSD) is a syndrome characterised by severe distal pain and vasomotor changes. It is believed to be caused by sympathetic nervous system overactivity. Trauma is the most frequent precipitant event. An association with amyotrophic lateral sclerosis (ALS) has been reported only once. We report three patients with ALS in whom the occurrence of RSD, in one of them at a very early clinical stage, seemed to have precipitated a more rapid clinical evolution. New sprouting re-innervating fibres have abnormal ion channels which might increase the risk of RSD. On the other hand, motor changes have been described in RSD, as well as motor strength improvement after RSD treatment. The complex relation of ALS with RSD is discussed. In all ALS patients pain followed by further loss of function should prompt a search for RSD.- - - - - - - - - - ranking = 1keywords = dystrophy (Clic here for more details about this article) |
10/252. reflex sympathetic dystrophy arising in a patient with familial mediterranean fever.A 14-year-old girl with familial mediterranean fever (FMF) had had acute attacks of fever, abdominal pain, and arthritis for 4 years. Her last arthritis attack was protracted, leading to reflex sympathetic dystrophy (RSD) in her right lower extremity. Physical therapy along with sympathetic ganglion block and corticosteroid therapy was used for the treatment. To our knowledge, this is the first reported case of RSD arising in a patient with FMF. Early recognition of RSD in FMF patients is important, and physical therapy should be applied along with medical treatment.- - - - - - - - - - ranking = 1keywords = dystrophy (Clic here for more details about this article) |
