Studies using resources of a public family health program to estimate the prevalence of chronic daily headaches (CDH) are lacking. ⋯ The prevalence of CDH in the rural area of Brazil is similar to what has been reported in previous studies. A significant proportion of them have psychiatric comorbidities and/or TMD. In this sample, comorbidities were as frequent as reported in convenience samples from tertiary headache centers.

Comparative Study
An analysis of migraine triggers in a clinic-based population.
Many migraineurs report attack "triggers," but relatively few published data exist regarding the relative prevalences of individual triggers, variations related to gender, duration of migraine or migraine subtype, or the existence of any regional variations in the prevalences and distributions of triggers. ⋯ A large majority of migraineurs report migraine attack triggers, and the triggers most commonly reported include emotional stress, a disrupted sleep pattern, and various odors. These findings do not appear to vary according to geographic region or race/ethnicity. Among the triggers, MM appears inclined to provoke headache that is more severe, less amenable to treatment, or longer in duration than headaches that occur at other times during the cycle.

Case Reports
Hemicrania continua: a second case in which the remitting form evolved from the chronic form.
We report the case of a woman with a 15-year history of chronic hemicrania continua, which over time evolved to remitting hemicrania continua. This is the second reported case in the literature documenting this transition.

Burning mouth syndrome is a chronic pain condition characterized by burning, painful sensations within the oral cavity. A patient developed symptoms of burning mouth syndrome after initiating topiramate treatment for headache prevention. The symptoms resolved when the medication was discontinued, and the association was replicated upon re-challenge of the drug.

Further questions need to be addressed in the evaluation of locus of control (LOC) in headaches, such as reducing scale length and adapting them to diverse cultural environments, as in the case of Spain. ⋯ The so-called Headache-Specific Locus of Control Scale-Short Form 9 has turned out to be a parsimonious (9 items), valid, and reliable measure of headache LOC.
