Migraine is included in the top-ten disabling diseases and conditions among the Western populations. Non-invasive neurostimulation, including the Cefaly® device, for the treatment of various types of pain is a relatively new field of interest. The aim of the present study was to explore the clinical experience with Cefaly® in a cohort of migraine patients previously refractory or intolerant to topiramate prophylaxis. A prospective, multi-center clinical study was performed in patients diagnosed with episodic or chronic migraine with a previous failure to topiramate treatment requiring prevention with Cefaly® according to the treating physician’s suggestion. A 1-month period of baseline observation was followed by a 3-month period of observation during the use of transcutaneous supraorbital nerve stimulation (t-SNS) with Cefaly® as the only preventive treatment. A small but statistically significant decline was shown over time in the number of days with headache (HA), the number of days with HA with intensity ≥5/10, and the number of days with use of acute medication after 3 months (p < 0.001 for all of the three changes). Twenty-three patients (65.7%) expressed their satisfaction and intent to continue treatment with Cefaly®. Compliance was higher among satisfied subjects compared to non-satisfied subjects. None of the explored factors were significantly associated with the reason for the failure of topiramate. Three-months of preventive treatment for episodic or chronic migraine with t-SNS proved to be an effective, safe and well tolerated option for the treatment of patients with migraine who were intolerant or did not respond to topiramate.

Evidence on whether the therapeutic effect and good safety profile of onabotulinumtoxinA (Botox®) in chronic migraine (CM) patients is maintained over long term treatment is still limited. We herein aimed at assessing whether there is a sustained benefit and good safety with repeated onabotulinumtoxinA sessions in CM over more than three years of treatment. We prospectively enrolled 65 CM patients, who were classified as responders after three sessions of onabotulinumtoxinA and were eligible to further continue treatment. Data documenting longitudinal changes from the trimester after the third onabotulinumtoxinA administration (T1) to the trimester after completing two years of treatment (T2) and eventually to the trimester after completing three years of treatment (T3) in (i) mean number of monthly headache days (ii) migraine severity as expressed by the mean number of days with peak headache intensity of > 4/10, and (iii) mean number of days with use of any acute headache medication, were prospectively collected from patients’ headache diaries. A total of 56 (86.1%) of 65 patients achieved to attain onabotulinumtoxinA over three years. At T3, a significant reduction in mean monthly headache days was evident, compared to T1 (3.4 ± 1.7 vs 7.2 ± 3.8; P < 0.001) with diminished mean number of monthly days with peak headache intensity of more than 4/10 and a significant change in days using acute headache medications per month between T1 and T3 (2.8 ± 1.3 vs 4.7 ± 3.2; P < 0.001). Significant changes were also noticed in all efficacy variables from T2 to T3. Therapy was safe and well tolerated with low rates of adverse events or drop-outs. The long -term treatment with onabotulinumtoxinA proved effective, safe and well tolerated over three years. Our findings support the strategy to consistently deliver sessions of use of onabotulinumtoxinΑ over long time in CM patients (Trial registration NTC03606356, registered retrospectively, 28 July 2018).

Paclitaxel-based regimens are frequently associated with the development of peripheral neuropathy. The autonomous nervous system (ANS) effects, however, of this chemotherapeutic agent remain unexplored. We investigated a group of 31 female patients with ovarian cancer receiving treatment with paclitaxel and carboplatin, as well as a group of 16 healthy age- and gender-matched healthy volunteers. All study participants completed a questionnaire and were assessed neurophysiologically at three time points (baseline, 3–4 months and 6–8 months following the onset of chemotherapy). The evaluation of the ANS included assessment of the adrenergic cardiovascular function (orthostatic hypotension-OH), parasympathetic heart innervation (30/15 ratio) and sympathetic skin response (SSR). At the 3–4 months ANS assessment, 19.2 % of the patients had systolic OH and the same percentage had diastolic OH, but at the 6–8 months evaluation no patient had systolic OH and only 13.8 % had diastolic OH. The values of the 30/15 ratio were significantly reduced at both time points, whereas the SSR was not affected. Combined paclitaxel and carboplatin chemotherapy is associated with significant effects on the parasympathetic heart innervation and occasionally with effects on the adrenergic cardiovascular reaction. The SSR remained unaffected. Physicians should be alert to the possibility of these treatment-emergent side effects, so as to monitor ANS parameters and introduce treatment modifications accordingly. Our findings however, should be validated in larger cohorts.

We sought to assess the effectiveness of combining dual therapy with onabotulinumtoxinA (BTX) add-on to anti-calcitonin gene-related peptide (CGRP) monoclonal antibodies (anti-CGRP MAbs) in treatment-refractory patients with chronic migraine (CM). We retrospectively reviewed the medical files of 19 treatment-refractory patients with CM who had failed to two oral migraine preventatives, at least three consecutive BTX cycles (less than 30% response rate), at least three consecutive sessions with either fremanezumab or erenumab (less than 30% response rate), and were eventually switched to dual therapy with BTX add-on to any of the already-given anti-CGRP MAbs. We then assessed from baseline to each monotherapy or dual intervention predefined efficacy follow-up the changes in the following efficacy outcomes: (i) monthly headache days (MHD), (ii) monthly days with moderate/severe peak headache intensity, and (iii) monthly days with intake of any acute headache medication. Response (50% reduction in MHD) rates, safety, and tolerability were also determined. In the majority of cases (n = 14), dual targeting proved effective and was associated with clinically meaningful improvement in all efficacy variables; 50% response rates (also disability and QOL outcomes) coupled with favorable safety/tolerability. Our results advocate in favor of the view that dual therapy is effective and should be considered in difficult-to-treat CM patients who have failed all available monotherapies.

The aim of this study was to record the demographic and epidemiological data on adult patients with headache who attend the emergency department (ED) and the diagnoses that made by the neurologists in the ED of a tertiary care hospital in metropolitan Thessaloniki (Greece). In an open prospective study, demographic and epidemiological data were collected on all patients who reported headache (as chief complaint or not) and presented to the ED of Papageorgiou Hospital between August 2007 and July 2008. Headache patients accounted for 1.3% of all ED patients and for 15.5% of patients primarily referred to the ED neurologist. Tension type headache was the most frequent diagnosis, followed by secondary headaches and migraine. The large number of patients without final ED diagnosis and ward admission for further evaluation sheds a light on the immense workload of Greek ED physicians. Furthermore, we found evidence for the misuse of Emergency Medical Services by chronic headache patients. These findings indicate shortcomings in the pre-hospital (primary care) management of headache patients in the Greek National Health System to an extent unreported so far.

Objective: this post hoc analysis aimed to evaluate the efficacy of fremanezumab in difficult-to-treat chronic migraine (CM) patients with and without psychiatric comorbidities (PCs), mainly anxiety and/or depression. Methods: We assessed data from CM patients with and without PCs who failed at least 3 preventives and eventually received at least 3 consecutive monthly doses of fremanezumab 225 mg. Outcomes included the crude response (≥50% reduction in monthly headache days (MHDs)) rates to fremanezumab from the baseline to the last clinical follow-up. The changes in MHDs; MHDs of moderate/greater severity; monthly days with intake of abortive medication; and the proportion of patients’ changing status from with PCs to decreased/without PCs were also compared. Disability and quality of life (QOL) outcomes were also assessed. Results: Of 107 patients enrolled, 65 (60.7%) had baseline PCs. The percentage of patients with (n = 38/65; 58.5%) and without (n = 28/42; 66.6%) PCs that achieved a ≥50% reduction in MHDs with fremanezumab was comparable (p = 0.41), whereas MHDs were significantly reduced (difference vs. baseline) in both patients with PCs (mean −8.9 (standard error: 6.8); p < 0.001) and without PCs (−9.8 (7.5); p < 0.001). Both groups experienced significant improvements in all other efficacy, disability, and QOL outcomes at comparable rates, including in MHD reduction. A significant proportion of fremanezumab-treated patients with baseline PCs de-escalated in corresponding severities or even reverted to no PCs (28/65; 43.1%) post-fremanezumab. Conclusions: fremanezumab appears to be effective as a preventive treatment in difficult-to-treat CM patients with and without PCs while also being beneficial in reducing the severity of comorbid anxiety and/or depression.
