Reflex sympathetic dystrophy in two young females.

Reflex sympathetic dystrophy in paediatric patients is a rarely recognized pain syndrome probably of neurovascular origin. The manifectations in two young females consisted of disabling pain and localized hyperesthesia in lower extremities without evident trauma. Sympathetic block followed by active mobilization and, in the patient with atrophic changes, lumbar sympathectomy, resulted in complete recovery. Reflex sympathetic dystrophy should be considered in the differential diagnosis of pain and tenderness in an extremity.

Reflex sympathetic dystrophy in children.

Two pediatric patients had reflex sympathetic dystrophy, which has been well described in adults but is rarely recognized in children. The syndrome consists of continuous pain, hyperesthesia, and autonomic symptoms occurring in an extremity, usually following trauma. The various types of presentation, differential diagnosis, and modes of therapy are discussed.

Skin potential and EMG changes induced by cutaneous electrical stimulation. II. Subjects with reflex sympathetic dystrophies.

In a group of patients suffering from reflex sympathetic dystrophies, the skin potential and EMG responses induced by electrical stimuli applied to the skin were recorded in the four limbs in order to study somato-sympathetic and somato-motor reflexes. In most patients, the amplitude, delay and shape of the cutaneous responses as well as the pattern of the EMG responses were different from those observed in normal subjects. In particular, it was possible to correlate the pattern of the cutaneous and muscular responses with the severity of the disease. The cutaneous sensory thresholds to electrical stimuli (tactile, tingling and pain threshold) showed different values in the dystrophic and in the contralateral limb. In all patients, a block of the sympathetic chain ipsilateral to the dystrophic limb was performed with local anesthetics. 1 h after the block, the cutaneous responses disappeared not only in the blocked limb but also in the contralateral limb. 48 h after the block, muscular and cutaneous responses as well as sensory thresholds showed a pattern similar to that observed in normal subjects. These findings show that the sympathetic block provides a resetting of the sensory thresholds and reflexes.

The reflex sympathetic dystrophy syndrome. A comprehensive analysis using fine-detail radiography, photon absorptiometry, and bone and joint scintigraphy.

Nine patients with reflex sympathetic dystrophy were examined. Clinical manifestations suggesting arthropathy were supported by radiographic demonstration of juxta-articular and subchondral bone erosions and by radionuclide demonstration of increased activity localized in the joint regions. Aggressive demineralization was demonstrated by fine-detail radiography and consisted of endosteal and intracortical excavation and subperiosteal and trabecular bone resorption. A one-third reduction in bone mineral was confirmed by quantitative analyses. Newer modalities of study have aided in the documentation of arthropathy in reflex sympathetic dystrophy and have helped in defining the patterns of aggressive bone resorption.

The reflex sympathetic dystrophy syndrome. II. Roentgenographic and scintigraphic evidence of bilaterality and of periarticular accentuation.

Patchy osteoporosis is the primary roentgenologic manifestation of the reflex sympathetic dystrophy syndrome (RSDS). As recent clinical and histologic data suggested articular changes in RSDS, fine-detail roentgenograms were obtained in eight consecutive patients. Juxta-articular and soft-tissue swelling, osteoporosis and erosions of the subchondral bone were found. 99mTcO4 and 99mTc-EHDP scintigraphy showed localization of nuclide predominantly in the juxta-articular tissues. Serial roentgenographic, scintigraphic and quantitative bone densitometric measurements showed changes that reflected the clinical course of the disease.

The reflex sympathetic dystrophy syndrome. I. Clinical and histologic studies: evidence for bilaterality, response to corticosteroids and articular involvement.

Eleven consecutive patients fulfulling criteria for the reflex sympathetic dystrophy syndrome (RSDS) were studied by quantitative clinical methods, providing measurements of swelling (ring size), tenderness (dolorimeter) and functional capacity (grip strength). The predominantly affected extremity was clearly identified by these technics and its serial progress determined in six patients. Corticosteroid therapy predictably resulted in improvement of all treated patients. Greater tenderness was found in the joints than in the interjoint areas, indicating a possible accentuation of the disease process in juxta-articular tissues. Synovial biopsy specimens in four patients were abnormal, and the histology was presented in detail for the first time. All patients showed bilateral involvement during the study, providing evidence for a central neural mechanism in the RSDS.

Reflex sympathetic dystrophy.

This paper describes a patient with typical post-traumatic Sudeck's atrophy of the right foot, who subsequently developed an atraumatic, painful osteoporosis of the left foot and right knee. It is suggested that cases of 'migrating osteolysis' and 'transient osteoporosis' of the lower limbs be grouped with classical Sudeck's atrophy as a reflex sympathetic dystrophy; Theories of pathogenesis have been reviewed and a possible theory of causation in atraumatic cases is presented.
