Insights
Red ear syndrome (RES) is a highly specific indicator of pediatric migraine, often linked to shared trigeminal-autonomic reflex pathways. This finding aids in diagnosing migraine in children.
Area of Science:
- Neurology
- Pediatrics
Background:
- Previous research suggests a link between red ear syndrome (RES) and pediatric migraine.
- The study aimed to evaluate RES frequency, specificity, and sensitivity in pediatric migraineurs.
- Investigating the pathophysiological mechanisms of RES in migraine was also a key objective.
Purpose of the Study:
- To determine the frequency, specificity, and sensitivity of red ear syndrome (RES) in children with migraine.
- To explore the pathophysiological mechanisms underlying the association between RES and migraine in pediatric patients.
Main Methods:
- 226 children (aged 4-17) with headaches were enrolled.
- Migraine diagnosis was confirmed in 172 children (76.4%).
- Statistical analysis, including univariate and multivariate logistic regression, was performed to identify associations.
Main Results:
- Red ear syndrome (RES) occurred in 23.3% of migraine patients, significantly more often than in other headache types (p < .0001).
- RES demonstrated high specificity (96.3%) and positive predictive value (95.3%) for pediatric migraine.
- Associations were found between RES and male gender, throbbing pain, vomiting, and phonophobia, with male gender, throbbing pain, and vomiting confirmed by multivariate analysis.
Conclusions:
- Red ear syndrome (RES) serves as a highly specific diagnostic sign for migraine in children.
- The association of RES with migraine features suggests a shared pathophysiological background, potentially involving the trigeminal-autonomic reflex.
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 predictive value (96.3 and 95.3%, respectively). According to the univariate statistical analysis, RES showed a statistically significant association with male gender, throbbing quality of the pain, vomiting and phonophobia. It was confirmed by a multivariate stepwise logistic regression model only for the throbbing quality of the pain, vomiting and male gender.
Conclusions:
Our study showed that (i) in children, RES is a highly specific sign for migraine. In addition, the evidence of an association of RES with some migraine features partially provoked by the parasympathetic system supports the hypothesis of a shared pathophysiological background (e.g. via the activation of the trigeminal-autonomic reflex).
