Household income is associated with attack frequency, but not with the prevalence of headache: an analysis of self-reported headache in the general population in Germany.

Background: Headache disorders are among the most prevalent neurological disorders worldwide. However, whether groups differing in socioeconomic position (SEP) are disproportionately affected by headache disorders has not yet been adequately clarified. Our aim was to analyse (1) the headache prevalence by socioeconomic position (SEP) and (2) the attack frequency by SEP in a German population-based adult sample.

Relationship between Contingent Negative Variation and afterimage duration in migraine patients.

Background: Abnormalities in electrocortical parameters and persistence of afterimage after visual stimulation are known to occur in migraine patients. The results of studies on Contingent Negative Variation (CNV) and afterimage persistence in migraine patients suggest a link between these two phenomena and a connection to the pathomechanism of migraine.

Objectives: To date, no studies have investigated both afterimage duration and CNV parameters in the same subjects.

Comparison of empathy profiles of medical students at the start and in the advanced clinical phase of their training.

Background: The National Competence Based Catalogue of Learning Objectives for Undergraduate Medical Education (NKLM) cites empathy as a basic competence for medical doctors. Based on a multidimensional concept of clinical empathy, empathy profiles of medical students at the start of their training and in the 9 semester were identified and compared in order to draw conclusions for the conception of effective course offers.

Method: Using the Saarbrücker Personality Questionnaire on Empathy (SPF-IRI), self-rated empathy was recorded in a cross-sectional study of medical students (1 semester: N=192/9 semester: N=221).

Efficacy of cranial electrotherapy stimulation in patients with burning mouth syndrome: a randomized, controlled, double-blind pilot study.

Background: The Burning mouth syndrome (BMS) is a chronic pain syndrome characterized by a burning sensation in the oral mucous membranes. The etiology and pathophysiology of BMS is largely unexplained. To date, there is no evidence-based treatment strategy for BMS.
