Prevalence of red ear syndrome in juvenile primary headaches.
2010
Background: Previous studies have suggested a relationship between ‘red ear syndrome’ (RES) and pediatric migraine. Aims of this study were (i) to assess the frequency, specificity and sensitivity of RES in a population of pediatric migraineurs and (ii) to establish the pathophysiological mechanisms of RES associated with migraine. Methods and results: A total of 226 children suffering from headache (aged 4–17 years) were enrolled. One hundred and seventy-two (76.4%) were affected by migraine, the remaining 54 (23.6%) by other primary headaches. RES was followed significantly more frequently by migraine (23.3%; p < .0001), and was characterized by high specificity and positive predictiv…
The red ear syndrome and migraine: the role of the parasympathetic system in a complex and intriguing clinical association
2010
Background and aims: The red ear syndrome (RES) is a rare syndrome characterized by burning pain and cutaneous erythema in the ear. It is probably due to an autonomic dysfunction, because of a hypofunction of sympathetic and/or a hyperactivity of parasympathetic control. We have previously described an intriguing association with migraine. In the present study, we have investigated the pathophysiological links between the RES and the clinical features of migraine, and pointed out the crucial role of the parasympathetic system. Methods: A total of 172 young migraine sufferers (92 M and 80 F, aged 4–17 years) underwent a clinical and instrumental evaluation. A semi-structured interview about …
