A Nursing Intervention Increases Quality of Life and Self-Efficacy in Migraine: A 1-Year Prospective Controlled Trial.

OBJECTIVES: To compare the impact of a combined nursing and medical approach to a medical follow-up only on headache outcomes, quality of life, and self-efficacy in a cohort of migraineurs. BACKGROUND: Interdisciplinary approaches have been proposed for migraine management. A nursing intervention could improve patient outcomes. METHODS: We prospectively studied new patients referred to our tertiary headache center for migraine. The control group was followed by a physician; the active group was also followed by a nurse with a personalized intervention including adaptation of the lifestyle. RESULTS: Two hundred patients (176 women and 24 men, mean age 40 years old) were included and classified according to headache frequency. Each group was followed for 12 months with daily headache diaries. One hundred and sixty-two completed the study. There were no significant differences between groups for the decrease in headache days, the percent of chronic patients reverting to episodic status or the cessation of medication overuse. Patients in the control group were more likely to find a successful prophylaxis (55.6 vs 27.7%, P = .002). Despite this, the mean decrease in HIT-6 scores at month 8 was 5.23 ± 9.18 for the active group compared with a decrease of 2.10 ± 9.27 for the control group (P = .030, clinically significant difference of 3.13). Headache Management Self-Efficacy Scale (HMSE) scores, representing the feeling of self-efficacy, increased by 14.35 ± 18.41 for the active group vs 4.69 ± 21.22 in the control group (P = .002). CONCLUSION: A nursing intervention can lower the impact of migraines on the patient's life. The improvement in the HIT-6 score in this study was correlated with improvements in self-efficacy.

Neurostimulation for Refractory Cervicogenic Headache: A Three-Year Retrospective Study.

BACKGROUND: Occipital nerve stimulation (ONS) has been used for the treatment of neuropathic pain conditions and could be a therapeutic approach for refractory cervicogenic headache (CeH). AIM: The aim of this study is to assess the efficacy and safety of unilateral ONS in patients suffering from refractory CeH. METHODS: We conducted a retrospective chart review on patients implanted from 2011 to 2013 at CHUM. The primary outcome was a 50% reduction in headache days per month. Secondary outcomes included change in EuroQol Group Visual Analog Scale rating of health-related quality of life (EQ VAS), six item headache impact test (HIT-6) score, hospital anxiety and depression scale (HADS) score, work status, and medication overuse. RESULTS: Sixteen patients fulfilled the inclusion criteria; they had suffered from daily moderate to severe CeH for a median of 15 years. At one year follow-up, 11 patients were responders (69%). There was a statistically significant improvement in the EQ VAS score (median change: 40 point increase, p = 0.0013) and HIT-6 score (median change: 17.5 point decrease, p = 0.0005). Clinically significant anxiety and depression scores both resolved amongst 60% of patients. At three years, six patients were responders (37.5%). Out of the 11 responders at one-year post implantation, five had remained headache responders (R-R) and one additional patient became a responder (NR-R). There was a statistically significant improvement in the EQ VAS score (median change: 15 point increase, p = 0.019) and HIT-6 score (median change: 7.5 point decrease, p = 0.0017) compared with baseline. Clinically significant anxiety and depression scores both, respectively, resolved among 22.5% and 33.9% of patients. Five out of seven disabled patients were back to work. CONCLUSION: ONS may be a safe and effective treatment modality for patients suffering from a refractory CeH. Further study may be warranted.

Real-Life Response to Erenumab in a Therapy-Resistant Case Series of Migraine Patients From the Province of Québec, Eastern Canada.

BACKGROUND AND OBJECTIVE: Erenumab is the first migraine-specific preventive therapy approved by Health Canada since the approval of onabotulinumtoxinA 10 years ago. It is one of four calcitonin gene-related peptide antagonist monoclonal antibodies that have been commercialized worldwide for use in the headache pipeline. The objective of our study was to determine real-life efficacy of monthly erenumab for the prevention of migraine in a small case series of difficult-to-treat patients followed at a tertiary headache clinic from the Canadian province of Québec. METHODS: We performed a retrospective chart audit of patients having failed four or more conventional migraine oral preventive therapies and who were treated with monthly self-administered subcutaneous erenumab (70 or 140 mg/mL dose) over a 1-year period. We assessed the patients' baseline characteristics, response to treatment, and tolerability. RESULTS: A total of 18 patients with a diagnosis of high-frequency episodic migraines or chronic migraine met criteria (83.3% female; mean age: 48.7 years; mean duration of migraine condition: 32.9 years). Patients self-administered erenumab using a prefilled disposable autoinjector on a monthly basis; 16 patients received a 140 mg/mL dosage, two patients received a 70 mg/mL dosage. At 1 year follow-up, 50% of patients reported ≥ 50% reduction in migraine frequency and were deemed responders. Patients attempted six doses of erenumab therapy prior to discontinuation for non-response, except for two patients with other concomitant chronic pain conditions, who required ten doses to reach a 50% response. For the overall cohort, there was a decrease of 5.2 monthly migraine days; 9 days for responders and 1.3 days for non-responders (t-test (df = 16) = - 2.77, p = 0.014). There was an additional decrease of 7 monthly non-migraine days amongst patients with unremitting daily headaches; 8 days for responders and 5 days for non-responders (p > 0.05). There was a decrease of 5.4 monthly days using acute analgesics; 8.9 days for responders and 2 days for non-responders (T(16) = - 2.33, p = 0.033). The overall mean reduction in disability using the Headache Impact Test (HIT-6) score was 5.6 points; only responders showed a reduction in HIT-6 severity category (p > 0.05). The most commonly reported adverse event was constipation (16.7%), which did not lead to treatment discontinuation and was successfully managed in all patients with early counselling and intervention. CONCLUSION: This study supports the efficacy of erenumab in a case series of therapy-resistant migraine patients from the region of Québec. A high rate of previously failed preventive oral agents and medication overuse did not predict response in our patient cohort. In the presence of real-world complexity factors, such as psychological distress, regular opioid consumption and concomitant chronic pain conditions, a longer therapy trial may be warranted in obtaining optimal response.

Facebook, Instagram, Reddit and TikTok: a proposal for health authorities to integrate popular social media platforms in contingency planning amid a global pandemic outbreak.

In December 2019, a new severe respiratory coronavirus infection (COVID-19) was detected and has since spread across the globe to be ultimately declared a pandemic by the World Health Organization on March 11, 2020. For physicians and allied medical professionals, the period since has been marked by an increased and rapidly changing flow of information from multiple regional, national and international health authorities, regulating bodies and professional associations. Although social media platforms have an active presence in the instant dissemination of information and medical professionals display active participation in them, traditional channels such as email are still being emphasized as a means of communication. This article discusses the opportunities offered by social media platforms such as Facebook, Reddit and TikTok to disseminate medical information both for the use of physicians and as a means to communicate essential information to the public at large.

A Case Report of Refractory Notalgia Paresthetica Treated with Lidocaine Infusions.

BACKGROUND Notalgia paresthetica is a neuropathic condition that manifests as a chronic itch in the thoraco-dorsal region. It is often resistant to treatment, and specific guidelines for its management are lacking. As such, we present a treatment approach with intravenous lidocaine infusions. CASE REPORT The case involves a 50-year-old woman with spinal cord injury caused by an epidural abscess. The patient developed notalgia paresthetica and sublesional neuropathic pain following its drainage. In the course of her pain management, she was treated with intravenous lidocaine which resulted in profound relief of notalgia paresthetica. CONCLUSIONS Intravenous lidocaine was effective in relieving neuropathic itch in the patient case presented.

A case report of complex auricular neuralgia treated with the great auricular nerve and facet blocks.

BACKGROUND: The great auricular nerve is a cutaneous branch of the cervical plexus originating from the C2 and C3 spinal nerves. It innervates the skin over the external ear, the angle of the mandible and the parotid gland. It communicates with the ansa cervicalis. Great auricular neuralgia is rarely diagnosed in clinical practice and can be refractory. We present a new approach using ultrasound-guided nerve blocks. CASE: We present a case of a 41-year-old female with paroxysmal ear pain accompanied by dysautonomia, tingling in the tongue, dysphagia, dysarthria and abdominal symptoms. No significant findings were found on cervical and brain imaging. The patient responded partially to a great auricular nerve block. A combined approach using this block with facet block of C2 and C3 induced a more pronounced and prolonged benefit. CONCLUSION: Great auricular neuralgia is not often encountered in practice and can be accompanied by symptoms originating from the ansa cervicalis network. A combined approach of nerve blocks can be considered in refractory cases.

Ultrasound-Guided Trigger Point Injection for Serratus Anterior Muscle Pain Syndrome: Description of Technique and Case Series.

Chronic chest pain is a challenge, and serratus anterior muscle pain syndrome (SAMPS) is often overlooked. We have developed an ultrasound-guided technique for infiltrating local anesthetics and steroids in patients with SAMPS. In 8 patients, the duration of chronic pain was approximately 19 months. Three months after treatment, all patients had experienced a significant reduction in pain. Infiltration for SAMPS confirms the diagnosis and provides adequate pain relief.
