Reflex sympathetic dystrophy associated with extraforaminal disc herniation at the L5-S1 level.

We report an association between an extraforaminal disc herniation at the L5-S1 level causing an L5 radiculopathy and a reflex sympathetic dystrophy (RSD) in the affected foot. This is only the second reported case of a disc herniation at this level causing an RSD syndrome. We opted to treat both problems through a retroperitoneal approach involving a discectomy and a surgical sympathectomy. There was immediate and lasting relief from all symptoms, which has been maintained at 18 months' follow-up. The possible mechanisms for this condition are discussed as well as the various treatment options.

Reflex sympathetic dystrophy syndrome in stroke patients with hemiplegia-three phase bone scintigraphy and clinical characteristics.

In an attempt to investigate the correlation between three phase bone scintigraphy (TPBS) and the clinical manifestation of reflex sympathetic dystrophy syndrome (RSDS) in the upper extremity of hemiplegia, we collected 30 patients with cerebral vascular accidents (CVA) confirmed by head computed tomography (infarction or hemorrhage) within 3 months of their CVA event. All patients received TPBS after admission. Clinical assessment for the development of the RSDS was done at least 3 months (268 +/- 120 days) after the stroke. The correlation between the development of RSD and certain clinical variables (including sex, age, side affected, caused of stroke, and motor stage) were analyzed. Twelve patients (40%) manifested definite or probable RSDS, as assessed by Tepperman's criteria, during the follow-up period. Nineteen patients (63%) exhibited radionuclide evidence of RSDS based on delayed bone scan criteria performed within 3 months (43 +/- 25 days) of the stroke. The positive delayed image of TPBS demonstrated a sensitivity = 92%; specificity = 56%; positive predictive value = 58%, and negative predictive value = 91%. The Kappa statistics for agreement between positive bone scan and RSDS development was 70% (Kappa = 0.43, p < 0.05). Neither sex, age, side affected, cause of stroke, or motor stage had a significant correlation with clinical RSDS. In conclusion, TPBS is a useful screening tool for the development of RSD in hemiplegic patients. However, the diagnosis of RSDS depends on the clinical evaluation and that TPBS as an adjunct assessment of RSDS must be interpreted with caution.

Reflex sympathetic dystrophy (algoneurodystrophy): temperature studies in the upper limb.

The temperature response of the hands to mild cold stress (20 degrees C for one minute) has been measured in 20 normal subjects, 20 patients with reflex sympathetic dystrophy (RSD) and 10 patients with chronic upper limb pain (CULP) of uncertain origin. The results of RSD and CULP groups were significantly (p less than 0.05) different from normal but were indistinguishable. For each patient, 11 variables obtained from the thermal stress test were compared with the normal range. Ten of the RSD group and seven of the CULP group had four or more abnormal variables and were considered to have a thermoregulatory abnormality. The thermal stress test is useful in the objective assessment of RSD. It is non-invasive, patient acceptable and reproducible.

[Three phase bone scintigraphy of reflex sympathetic dystrophy and its change with sympathetic blockade].

We examined three phase bone scintigraphy performed at various stages, covering 13 patients with reflex sympathetic dystrophy (RSD) of limbs. In three patients, changes following sympathetic nerve block were examined. In stage-1, radiation count in the affected limbs increased markedly in phases 1 to 3 as compared with the values in healthy limbs. In stage-2, radiation count decreased in phase-1, showed about the same level in phase-2, and maintained an increased level in phase-3. In stage-3, count decreased in phase-1 and 2, and showed about the same level in phase-3. In patients who received a chemical sympathectomy in its early stage, the count was found to have returned to normal level over a short period of time from phase 1 to 3. Three phase bone scintigraphy was considered useful in understanding the pathologic condition of RSD and follow-up evaluation of treatment mainly consisting of sympathetic nerve block.

The use of three-phase radionuclide bone scanning in the diagnosis of reflex sympathetic dystrophy.

One hundred forty-five consecutive three-phase radionuclide bone scans were reviewed. One hundred two of these were performed to evaluate pain in the hand. Of these, 23 patients clinically had reflex sympathetic dystrophy (RSD). The hand scans were performed by the three-phase technique. Phase I is a radionuclide angiogram. Phase II is the blood pool or tissue phase. Phase III consists of delayed images obtained 3 to 4 hours after radionuclide injection. Detailed analysis of the 145 three-phase radionuclide bone scans of the hand demonstrated that the diffuse increased tracer uptake in the delayed image (phase III) is diagnostic for RSD, with a sensitivity of 96% and a specificity of 98%. The two early phases (radionuclide angiogram and blood pool) were positive in only 45% and 52% of the RSD patients, respectively. The strictly interpreted delayed radionuclide image is extremely sensitive in the diagnosis of RSD and will facilitate the early diagnosis and subsequent treatment of this syndrome.

Cervical mass lesion presenting as reflex sympathetic dystrophy of the hand.

A case with multiple small joint swelling and skin dystrophic changes in the right hand was initially treated as seronegative non-specific arthritis. Later, a triple phase bone scan indicated reflex sympathetic dystrophy (RSD) and the primary lesion was shown on MRI scan to be a cervical cord mass with associated sub-acute haematoma. The case underscores the need to consider RSD in the differential diagnosis of such conditions and the importance of a detailed neurological examination in RSD with no local causative factor.

Health-related quality of life in chronic refractory reflex sympathetic dystrophy (complex regional pain syndrome type I).

The aim of this study was to find out which aspects of health-related quality of life (HRQL), measured with generic instruments, are important to patients with reflex sympathetic dystrophy (RSD) affecting the arm or leg. The Sickness Impact Profile 68 (SIP68), the Nottingham Health Profile (NHP), and the EuroQol-5D (EQ-5D) were completed by 54 patients suffering from RSD (33 arm, 21 leg). The scores of the three questionnaires for patients with an affected arm or leg are presented. Aspects relevant to patients with RSD of the arm include the NHP1 dimensions of pain (mean score: 63%), sleep (58%), and energy (45%), and the EQ-5D dimensions of pain (67% extreme), usual activities (76% some problems), and self care (76% some problems). Aspects relevant to patients with RSD of the leg include the SIP68 dimensions of social behavior (51%) and mobility control (46%), the NHP 1 dimensions of pain (mean score: 86%), mobility (54%), energy (53%), and sleep (52%), and the EQ-5D dimensions of mobility (81% some problems), pain (71% extreme), and usual activities (71% some problems). The study showed that applying generic HRQL instruments and measuring treatment effect with the dimensions scoring high provides a responsive instrument which at the same time gains information concerning dimensions not maximally responsive to a specific disease. Some dimensions which, on the basis of their label, might be expected to be important were found not to be so. After using this approach, clinicians can more directly focus treatment on specific areas that have been shown to affect a patient's HRQL.

Bilateral cingulumotomy in the treatment of reflex sympathetic dystrophy.

Bilateral anterior cingulumotomy has been used to treat psychiatric diseases and chronic pain. We report an interesting case involving a young woman who underwent cingulumotomy for the treatment of intractable total body pain secondary to generalized reflex sympathetic dystrophy. Her initial response after two procedures was excellent though 1 year later her pain recurred and was resistant to a subsequent cingulumotomy.

Electrical spinal cord stimulation in reflex sympathetic dystrophy: retrospective analysis of 23 patients.

OBJECT: The aim of the study was to assess retrospectively the clinical efficacy and possible adverse effects of electrical spinal cord stimulation (SCS) for the treatment of patients with reflex sympathetic dystrophy (RSD). METHODS: Twenty-three patients who suffered severe pain due to RSD were included in the study. The SCS system was implanted only after a positive 1-week test period. The visual analog scale (VAS) score for pain (1-10) was obtained in all patients prior to treatment, 1 month postimplantation, and at last follow up. At final follow-up examination, patients were asked to rate the effect of their treatment on the 7-point global perceived effect scale. Eighteen (78%) of 23 patients treated between 1991 and 1997 reported improvement during the test period. Permanent implantation of SCS system was not performed in the other five patients. Complications occurred in nine (50%) of 18 patients. The system was removed in three patients after implantation (17%). At the end of follow up (mean 32 months) 15 patients still had an implanted system. The mean pain score had decreased from 7.9 to 5.4 (p<0.001). In the other eight patients the pain score had not changed significantly. In 13 patients (57%) in whom the SCS system was implanted, clinical status had much improved or improved; these cases were regarded as successful. CONCLUSIONS: In this retrospective series, the majority of patients with RSD reported a subjective improvement after implantation of an SCS system.

Variation in measurements of range of motion: a study in reflex sympathetic dystrophy patients.

OBJECTIVE: To quantify the amount of variation attributed to different sources of variation in measurement results of upper extremity range of motion, and to estimate the smallest detectable difference (SDD) between measurements in reflex sympathetic dystrophy (RSD) patients. DESIGN: Two observers each measured in two sessions the range of motion of several upper extremity joints of RSD patients participating in an outcome study. SETTING: Department of Rehabilitation of a university hospital. SUBJECTS: Twenty-nine upper extremity RSD patients. MAIN OUTCOME MEASURES: The range of motion of forward flexion and external rotation of the shoulder, extension, flexion and supination of the elbow, palmar, dorsiflexion and ulnar, radial deviation of the wrist of affected and nonaffected sides, using a two-armed goniometer and an inclinometer. The measurement results were analysed using an analysis of variance according to the generalizability theory. RESULTS: The results indicate that observer and patient-observer were important sources of variation. The random error was the most important source of variation. Averaged over all ranges of motion the observer contributed 3.9% to the total variation, patient-observer interactions contributed 5.2% and the random error 20.3%. The SDD was smallest for elbow flexion, 7.1 degrees and 9.6 degrees and was largest for external rotation of the shoulder, 24.8 degrees and 28.7 degrees. The SDD was smaller for the nonaffected side as compared to the affected side for the majority of ranges of motion except elbow extension, wrist dorsiflexion, and radial and ulnar deviation. CONCLUSION: Clinically, our results indicate that range-of-motion measurements in RSD patients are subject to considerable variation and indicate that results of medical examinations in order to assess disability on the basis of range-of-motion measurements are subject to the same variation.

Electromotive administration of guanethidine for treatment of reflex sympathetic dystrophy: a pilot study in eight patients.

Persistent neuropathic pain is associated with diagnostic and therapeutic challenges that may be very difficult to resolve. This report describes eight patients with incapacitating, posttraumatic neuropathic pain characteristic of reflex sympathetic dystrophy (RSD) who were treated by electromotive administration of guanethidine into affected areas of skin. Following 1-5 treatments, six patients experienced complete resolution of all superficial symptoms of hyperalgesia, pain, pallor, coolness, and sweating of the affected areas. One patient demonstrated partial relief of these symptoms, and one patient failed to respond. The results of this preliminary study suggest that electromotive administration of the the sympatholytic agent, guanethidine, may be useful in the treatment of some types of neuropathic pain. These findings justify the implementation of further controlled studies.

Reflex sympathetic dystrophy: a sympathetically mediated pain syndrome or not?

Because of the controversy concerning the manner in which the sympathetic nervous system is involved in reflex sympathetic dystrophy (RSD), its name was changed to one having no mechanistic connotations. This article reviews the relevant literature in support of not only the taxonomical changes to complex regional pain syndrome (CRPS) but also provides evidence of sympathetic dysfunction demonstrated in animal models of neuropathic pain.

Reflex sympathetic dystrophy of the upper extremity--a 5.5-year follow-up. Part I. Impairments and perceived disability.

The aim of this retrospective and long-term follow-up study was to identify impairments resulting from reflex sympathetic dystrophy (RSD) of the upper extremity and to analyze the relationship between impairment and disability in RSD patients. The study group consisted of a referred sample of 65 RSD patients, with clinical signs in the upper extremity. RSD developed after fractures of the wrist or hand in 29 patients or after a carpal tunnel release in 9 patients. The mean interval between the RSD diagnosis and our evaluation was 5.5 (3-9) years (SD = 0.8). The main outcome measurements were the impairments assessed by standard physical examination. ADL and pain were quantified with a visual analogue scale (VAS). Pain was evaluated immediately before and after the physical examination and the perceived pain was determined in the week before the examination. Significant differences in impairments were found between the affected and the unaffected sides (p < 0.05). According to the AMA-guides, the impairments did not lead to disabilities. Significant correlations were found between VAS-ADL and VAS-pain in the last week prior to evaluation and full fist grip-strength. Pain seems to be the most disabling effect.

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.

The clenched fist syndrome. A psychiatric syndrome mimicking reflex sympathetic dystrophy.

We describe a patient with swelling and pain in his right hand, which persisted for 1 year after minimal trauma. We think this represents a case of "clenched fist syndrome," a conversion disorder with unique somatic features that is easily mistaken for reflex sympathetic dystrophy syndrome. Included is a comparison of other psychological illnesses in which unusual physical findings involve the hand.

[A case of reflex sympathetic dystrophy following a retinous surgery].

We present a case of a 54-year-old female with post-operative severe continuous ocular pain which occurred 3 months after retinal operation. Her general and mental conditions were good. We diagnosed it reflex sympathetic dystrophy and treated with stellate ganglion blocks (SGB) and continuous cervical epidural blocks. SGB and continuous cervical epidural blocks were effective. With increasing numbers of retinal surgery in recent years, more patients will suffer from postoperative ocular pain. We conclude that SGB or epidural block is useful for the therapy of ocular pain which can not be controlled by drugs and other therapy.
