Management of acute and chronic migraine

Comparing the Effect of Intranasal Lidocaine 4% with Peppermint Essential Oil Drop 1.5% on Migraine Attacks: A Double-Blind Clinical Trial

Background:

Prevalence of migraine, as a chronic neurovascular disorder, was approximately 10.3 and 23.1% among men and women, respectively, mostly in people younger than 40 years old. Migraine is prevalent in different geographic areas worldwide. The present study was designed to compare the impact of intranasal lidocaine 4% and peppermint essential oil drop 1.5% on migraine attacks.

Methods:

In this double-blind, parallel, randomized controlled trial, 120 adult patients with a diagnosis of migraine based on the International Headache Society criteria were treated with intranasal lidocaine drop 4% or peppermint essential oil drop 1.5% or placebo. Patients expressed their symptoms 5 and 15 min after dripping, and if they still had a headache after 15 min, they were given the second dose. Patients with a second dose of medication, 15 min later recorded their headache rate. All patients recorded their symptoms after 30 min. Symptoms of the patients were followed by a researcher through the phone and in-person after 2 months. Then, the questionnaires were filled.

Results:

In the present study, there was a significant difference among groups in headache intensity after treatment (P < 0.001). In 40% of the patients in the peppermint oil and lidocaine groups, the intensity of headache decreased. In the placebo group, fewer patients responded highly to the treatment, whereas 41.5% of patients in the lidocaine group and 42.1% of patients in the peppermint oil group responded to the treatment considerably.

Conclusions:

Concerning the findings of the present study, nasal application of peppermint oil caused considerable reduction in the intensity and frequency of headache and relieved majority of patients' pain similar to lidocaine. On the basis of findings of this study, it can be concluded that nasal menthol, such as lidocaine, can be used to relieve migraine headaches.

A Qualitative, Systems Thinking Approach to Study Self-Management in Women With Migraine

BACKGROUND

A dearth of effective and affordable treatment options has rendered nonpharmacological self-management a crucial part of living with migraine-a debilitating neurobiological condition without cure that disproportionately disables vulnerable women.

OBJECTIVE

The aim of the study was to describe the development and use of a systems thinking, problem-structuring data collection approach that was applied to the study of migraine self-management with women in diverse social locations.

METHODS

Two systems mapping activities were developed for use in focus groups: one to unpack a migraine episode (system support map) and the other (connection circle [CC]) to construct a mental model of self-management. Later in the process, a strengths-based problem-solving tool was developed to replace the CC.

RESULTS

The CCs-often enlightening for affluent participants-left marginalized women feeling overwhelmed and defeated, as a solution to one challenge became the cause of another. Through constant comparison analysis, we recalibrated the approach using a theory, clinical experience, and participant feedback and replaced the CC with a strengths-based problem-solving activity highlighting relationships and trade-offs in a more agential, actionable way.

DISCUSSION

Bringing a critical lens and strengths-based approaches to work with vulnerable populations can replace traditional deficit thinking in healthcare, developing options for leveraging resources and understanding complex health behaviors without losing sight of systemic, distributional justice issues. These systems thinking tools can provide a way to extrapolate the complexities of actual self-management behaviors and challenges faced by vulnerable women with migraine versus what they may be instructed to do by a medical model that does not always account for the social and structural determinants of equity and health.

Traditional Uses of Medicinal Plants from the Canadian Boreal Forest for the Management of Chronic Pain Syndromes

OBJECTIVE

Chronic pain is more prevalent in indigenous populations who often prefer traditional remedies over allopathic drugs. Our objective was to investigate the traditional uses of medicinal plants from the Canadian boreal forest for the management of chronic pain syndromes.

METHODS

We reviewed the most extensive database on medicinal plants used by aboriginal people of the Canadian boreal forest to investigate the plants used in the management of 3 of the most common chronic pain syndromes: arthritis/rheumatism; back pain; and headache/migraine. We also reviewed the pharmacology and phytochemistry literature to investigate concordance with indigenous knowledge.

RESULTS

A total of 114 medicinal plant species were reported, of which 27 (23.5%) were used to treat more than 1 chronic pain syndrome. Pharmacological or phytochemical evidence to explain plant function as chronic pain remedy was available in the literature for only 38 species (33%), with several species reported to have anti-inflammatory and analgesic properties effective in treating chronic pain syndromes.

CONCLUSIONS

Our study showed the potential of boreal plants as alternative and complementary medicines for the treatment of chronic pain syndromes that could be enhanced by further research on efficacy and safety issues.

The psychometric properties of the persian migraine-specific quality of life questionnaire version 2.1 in episodic and chronic migraines

Background. Migraine-specific quality of life (MSQ) is a valid and reliable questionnaire. Linguistic validation of Persian MSQ questionnaire, analysis of psychometric properties between chronic and episodic migraine patients, and capability of MSQ to differentiate between chronic and episodic migraines were the aims of this study. Method. Participants were selected from four different neurology clinics that were diagnosed as chronic or episodic migraine patients. Baseline data included information from MSQ v. 2.1, MIGSEV, SF-36, and symptoms questionnaire. At the third week from the baseline, participants filled out MSQ and MIGSEV. Internal consistency (Cronbach alpha) and test-retest reproducibility (intraclass correlation coefficients) were used to assess reliability. Convergent and discriminant validities were also assessed. Results. A total of 106 participants were enrolled. Internal consistencies of MSQ among all patients, chronic and episodic migraines, were 0.92, 0.91, and 0.92, respectively. Test-retest correlation of MSQ dimensions between visits 1 and 2 varied from 0.41 to 0.50. Convergent, item discriminant, and discriminant validities were approved. In all visits MSQ scores were lower in chronic migraine than episodic migraine; however, the difference was not statistically significant. Conclusion. Persian translation of MSQ is consistent with original version of MSQ in terms of psychometric properties in both chronic and episodic migraine patients.
