Following the publication of this article [1], the authors noticed that they incorrectly reported the Absolute risk of ischemic stroke in women aged 20 to 44 years in relation to the use of hormonal contraception and migraine status due to a miscalculation. They apologize for this misreported result.

A myofascial trigger point is defined as a hyperirritable spot in skeletal muscle that is associated with a hypersensitive palpable nodule in a taut band. It has been suggested that myofascial trigger points take part in chronic pain conditions including primary headache disorders. The aim of this narrative review is to present an overview of the current imaging modalities used for the detection of myofascial trigger points and to review studies of myofascial trigger points in migraine and tension-type headache. ⋯ Myofascial trigger points are prevalent in both migraine and tension-type headache, but the role they play in the pathophysiology of each disorder and to which degree is unclarified. In the future, ultrasound elastography may be an acceptable diagnostic test.

Several outcome studies have reported on the short- and long-term effects of migraine in selected clinical samples of children and adolescents. However, current knowledge of the course, incidence, and outcome predictors of frequent headaches in early adolescents in community populations is limited, and little is known about the long-term effects. Headache remains untreated in most of these young people. Here we examined the course, incidence, and outcome predictors of frequent headaches (at least once a week) over the long term (14 years) using previously assessed data at the baseline and 1-year follow-up of early adolescents. ⋯ Our findings suggest that gender, greater social impairment, and comorbid depressive symptoms are important indicators for both the short- and long-term prognosis of frequent headaches in early adolescents in community populations.

Multicenter Study
Impact of cluster headache on employment status and job burden: a prospective cross-sectional multicenter study.
Cluster headaches (CH) are recurrent severe headaches, which impose a major burden on the life of patients. We investigated the impact of CH on employment status and job burden. ⋯ CH might be associated with employment status. Most patients with CH experienced substantial burdens at work.
