Shoulder pain and reflex sympathetic dystrophy.

Shoulder pain has become one of the commonest clinical problems in modern North American society. The pathogenetic mechanisms vary widely, and often times, speculations about the underlying pathology have not been substantiated by investigative studies. In the past year, progress in our knowledge about shoulder pain has not been significant. We discuss the topic by dividing shoulder pain into four categories: 1) shoulder pain of local origin; 2) pain referred to the shoulder; 3) shoulder and neck pain; and 4) shoulder pain and reflex sympathetic dystrophy. It appears that a thorough history taking, an understanding of the psychosocial background of the patient, and a complete physical are equally important in the clinical evaluation of painful shoulders.

[A microneurographic analysis of minor reflex sympathetic dystrophy with increased skin sympathetic activity--report of a case].

A 48-year-old man developed swelling, redness, and allodynia in his left palm. Routine physical and neurological examinations revealed no abnormal findings except for left palmar hyperhidrosis. A clinical diagnosis of minor reflex sympathetic dystrophy with causalgia was made. Skin sympathetic activity (SSA), dominating palm sweating and skin vasoconstriction, and discharges of single afferent fiber from the rapidly adapting-type I (RA-I) unit were recorded microneurography from the median nerve at the cubital fossa. SSA obtained from the affected side was significantly increased compared with that from the normal (right) side. The receptive field of RA-I unit in this case was larger than those of normal controls. Enlargement of the receptive field might suggest presence of collateral sprouting in the injured nerve fibers. Allodynia in the left palm was suspected to be resulted from misdirect sprouting between A alpha . beta to A delta . C fibers. Excessive sympathetic out flow to the skin is considered to be the cause of palmar hyperhidrosis, swelling with redness, and lowered pain threshold, since pain threshold is under regulation of SSA. It is concluded that these sensory and autonomic symptoms were resulted from increased sympathetic out flow to the skin and collateral sproutings in the peripheral nerve fibers.

Reflex sympathetic dystrophy in cervical spinal cord injury patients.

Sixty consecutive patients admitted to the spinal cord injury unit at a Downey, California medical center were evaluated for hand and upper extremity pain. Patients averaged nine months postinjury and had an average age of 37 years. Seven patients (11.7%) complained of diffuse hand pain, swelling, and stiffness. All patients with complaints were evaluated with three-phase radionuclide scintigraphy. Six of those seven patients had scintigrams consistent with reflex sympathetic dystrophy (RSD), an overall incidence of 10%. Three of these six patients were treated with stellate ganglion blocks, which gave relief of symptoms and allowed return to their rehabilitation program. An awareness of RSD as a cause of pain in spinal cord injured patients should lead to earlier recognition and treatment.

Phantom pain with probable reflex sympathetic dystrophy: efficacy of fentanyl infiltration of the stellate ganglion.

BACKGROUND AND OBJECTIVES: The stellate ganglion can alleviate phantom pain of the upper extremity, possibly because of the presence in it of enkephalin receptors, as has been suggested by experimental and clinical reports. A case is reported in which fentanyl, instead of local anesthetic, was used for stellate ganglion block. METHODS: A 49-year-old man, with a left below-elbow amputation, presented with probable symptoms of reflex sympathetic dystrophy, pain and temperature changes at the stump, and phantom hand symptoms the English-language literature revealed no reports of the use of fentanyl infiltration of the stellate ganglion was performed for management of this condition. RESULTS: Significant alleviation of pain and sensation of warmth at the stump and in the phantom hand was achieved. CONCLUSIONS: Fentanyl infiltration of the stellate ganglion proved to be successful in the management of the pain and temperature sensation changes in the stump and phantom upper extremity.

Laser Doppler measurements of skin blood flow before, during, and after lumbar sympathetic blockade in children and young adults with reflex sympathetic dystrophy syndrome.

Changes in the skin capillary blood flow (SBF) and temperature before, during, and 1 hour after unilateral lumbar paravertebral sympathetic blockade (LSB) were studied simultaneously with laser Doppler flowmetry and thermometry in patients with reflex sympathetic dystrophy syndrome. The baseline flow measurements in the toes on the affected limb were significantly lower than in the contralateral limb (p less than 0.01). During LSB, a 10-fold increase in SBF was detected within 4 minutes after injection of a local anesthetic agent when the sympathetic blockade was effective; an increase of more than 1 degrees C in the skin temperature occurred within 11 minutes. Measurements 1 hour after blockade showed an 18-fold (mean) increase in SBF in the toes (p less than 0.0001) and a 2-fold (mean) increase in SBF in the thighs (p less than 0.001). There was a significant decrease in the skin blood flow in the contralateral toes after the sympathetic blockade (p less than 0.01). We conclude that laser Doppler flow measurements can be used to detect immediate onset of sympathetic blockade in patients under general anesthetic or conscious sedation.
