- Objective The aim of this study was to investigate knowledge about medication overuse headache (MOH) among pharmacy staff. Background MOH is a public health problem both in Sweden and in many other countries. Persons with MOH have limited contact with health care, and medications used are to large extent over-the-counter (OTC) medications. Therefore, pharmacists have an important role in, eg, advising these individuals about their medication use. Little is, however, known about the actual level of knowledge about MOH among pharmacy staff, which determines the quality of their advice to MOH sufferers. Methods A total of 326 questionnaires were distributed to 44 pharmacies in Gothenburg, Sweden. The questionnaire included background questions, questions about advice on headache treatment, source of knowledge about MOH, and questions on self-perceived and actual knowledge on MOH. Results The response rate was 70%. A majority of the pharmacy staff (90.6%) considered themselves to have knowledge about MOH to some or a greater extent. Almost half had learned about MOH through their university/vocational education. Only 8.6% knew that all 5 headache medications listed in the questionnaire can cause development of MOH, but 40% responded correctly on which treatment advice one can give a person with MOH. Actual knowledge on treatment advice differed significantly between groups of self-perceived knowledge. Conclusion The knowledge on MOH is insufficient among pharmacy staff, but with the proper knowledge, pharmacy staff is well positioned to effect both primary and secondary prevention of MOH. We suggest not only increasing educational efforts about MOH within pharmacy programs but also continuing education at the pharmacies for all staff. Further, it is also important to increase knowledge among pharmacy customers.

- Background.- Among the most common chronic pain conditions, yet poorly understood, are temporomandibular disorders (TMDs), with a prevalence estimate of 3-15% for Western populations. Although it is increasingly acknowledged that central nervous system mechanisms contribute to pain amplification and chronicity in TMDs, further research is needed to unravel neural correlates that might abet the development of chronic pain. Objective.- The insular cortex (IC) and cingulate cortex (CC) are both critically involved in the experience of pain. The current study sought specifically to investigate IC-CC functional connectivity in TMD patients and healthy controls (HCs), both during resting state and during the application of a painful stimulus. Methods.- Eight patients with TMD, and 8 age- and sex-matched HCs were enrolled in the present study. Functional magnetic resonance imaging data during resting state and during the performance of a pressure pain stimulus to the temple were acquired. Predefined seed regions were placed in the IC (anterior and posterior insular cortices) and the extracted signal was correlated with brain activity throughout the whole brain. Specifically, we were interested whether TMD patients and HCs would show differences in IC-CC connectivity, both during resting state and during the application of a painful stimulus to the face. Results.- As a main finding, functional connectivity analyses revealed an increased functional connectivity between the left anterior IC and pregenual anterior cingulate cortex (ACC) in TMD patients, during both resting state and applied pressure pain. Within the patient group, there was a negative correlation between the anterior IC-ACC connectivity and clinical pain intensity as measured by a visual analog scale. Conclusions.- Since the pregenual region of the ACC is critically involved in antinociception, we hypothesize that an increase in anterior IC-ACC connectivity is indicative of an adaptation of the pain modulatory system early in the chronification process.
