AIM OF THE STUDY: To analyze the epidemiological characteristics of Raynaud's syndrome in childhood.
PATIENTS AND METHODS: We conducted a nine-year-retrospective survey of children up to 17 y seen with Raynaud's syndrome. Charts were retrieved from pediatrics and dermatology outpatient units, and from the registry of capillaroscopy. A specific questionnaire was designed and missing data were completed after a phone interview of the parents.
RESULTS: A definite diagnosis of Raynaud's syndrome was ascertained in 23 patients with marked female predominance (SR = 0.27). Triggering factors were essentially a cold environment and emotions. The mean age at the diagnosis was 11 y (5 to 16 y) with an onset after ten years in 65% of cases. Eleven of these Raynaud's syndromes were secondary with ten connectivitis, eight remained essential and four were suspected to be secondary.
DISCUSSION: This series of pediatric Raynaud's syndromes was important according to scarcity of literature on this topic. The diagnosis is made upon exclusive clinical basis and we underline the high frequency of serious underlying conditions. Further etiologic investigations are mandatory for any pediatric patient with Raynaud's syndrome. The sensitivity (78%) and specificity (80%) of capillaroscopy were of interest in our patients; its prognosis value needs to be evaluated in a larger group of patients.
