The association between stress and headache: A longitudinal population-based study.

Introduction: We studied the association between stress intensity and headache frequency for tension-type headache (TTH), migraine and migraine with coexisting TTH (MigTTH).

Method: We studied a population-based sample of 5159 participants (21-71 years) who were asked quarterly between March 2010 and April 2012 about headache and stress. Log-linear regression in the framework of generalized estimating equations was used to estimate regression coefficients presented as percent changes to describe the association between stress intensity (modified visual analog scale (VAS) from 0 to 100) and headache frequency (days/month) stratified by headache subtypes and age groups and adjusted for sex, age, frequent intake of acute pain drugs, drinking, smoking, BMI and education.

Do illness perceptions predict pain-related disability and mood in chronic orofacial pain patients? A 6-month follow-up study.

Unlabelled: In our study, we investigated the predictive value of illness beliefs as measured by the revised illness perception questionnaire (IPQ-R) in the context of other clinical predictors in patients with chronic orofacial pain over a 6-month follow-up period. Consecutive patients (152) referred to the interdisciplinary orofacial pain service at the Centre for Dental and Oral Medicine and Cranio-Maxillofacial Surgery, University of Zurich received questionnaires to assess pain and pain-related disability, anxiety, depression as well as physical and mental quality of life at three time points: prior to treatment, 3 and 6 months after beginning of treatment.

Results: significant improvement was found over time for all outcome measures except mental quality of life.

PRISM (pictorial representation of illness and self measure): a novel visual instrument to assess pain and suffering in orofacial pain patients.

Aims: To use PRISM (Pictorial Representation of Illness and Self Measure), a visual instrument that has recently been developed and validated to assess suffering in patients with chronic physical illness, in orofacial pain patients and test for associations of PRISM with established assessment tools for pain, affective symptoms, and sleep. Of particular interest was the utility of PRISM as a screening tool for severely suffering patients.

Methods: One hundred and two orofacial pain patients recruited from a specialized outpatient service completed a questionnaire-based survey, including established assessment tools: the Visual Analog Scale (VAS), Graded Chronic Pain Scale (GCPS), the Hospital Anxiety and Depression Scale (HADS), and the Insomnia Severity Index (ISI), as well as a paper and pencil version of PRISM.

Enhanced negative feedback sensitivity of the hypothalamus-pituitary-adrenal axis in chronic myogenous facial pain.

Unlabelled: Dysregulations of the hypothalamus-pituitary-adrenal (HPA) axis, as a physiological substrate of stress, have been observed in patients with different stress-related and chronic pain disorders. In this study, we investigated possible dysregulations of the HPA axis in patients with masticatory muscles pain. In 20 patients with myogenous facial pain and 20 healthy controls, awakening cortisol responses, i.

[The Interdiscipilinary Orofacial Pain Consulting Service at the Center for Dental and Oral Medicine and Cranio-Maxillofacial Surgery, University of Zurich, Switzerland].

At the Center for Dental and Oral Medicine and Cranio-Maxillofacial Surgery of the University of Zurich, a new interdisciplinary pain consulting service was established in early 2005 due to the increasing number of referrals of orofacial pain patients to the center. This unit comprises specialists of various dental and medical disciplines as well as psychologists and physical therapists. This article highlights the most common clinical pictures of chronic orofacial pain patients and describes the organizational mechanisms associated with referrals to our interdisciplinary pain service.
