[Reflex sympathetic dystrophy].

OBJECTIVE

To describe eight patients with reflex sympathetic dystrophy in terms of clinical and laboratory characteristics and treatment.

DESCRIPTION

Eight children (four girls) with reflex sympathetic dystrophy were retrospectively analyzed. The diagnosis of reflex sympathetic dystrophy was based on the presence of pain in the distal extremities, local edema, vasomotor instability and impairment of sensibility. Two patients had associated systemic lupus erythematosus, one had juvenile idiopathic arthritis and one had Glanzmanńs thrombasthenia. Mean age was 11.5 years. Most of the patients had lower extremity involvement (7/8). The most important clinical signs were pain, edema and vasomotor instability in the affected extremity (8/8), functional impairment (7/8), and impaired sensibility (3/7). The erythrocyte sedimentation rate was abnormal in three patients and the bone scans in five. All patients received non-steroidal anti-inflammatory drugs and physical therapy with improvement of the symptoms in seven patients, until six months of treatment. Three patients were submitted to acupuncture with good response. One patient had a severe disease and received tricyclic antidepressants, with improvement more than one year after.

COMMENTS

Reflex sympathetic dystrophy should be included as part of the differential diagnosis of limb pains of childhood, so that physicians can make an earlier diagnosis and prevent functional impairment.
