Preferences and perceptions of 617 migraine patients on acute and preventive migraine treatment attributes and clinical trial endpoints.

BACKGROUND: To identify the preferences and perceptions of migraine patients for acute and preventive treatment options and to investigate which treatment outcomes are the most important. DESIGN AND METHODS: The authors performed a choice-format survey in a cohort of migraine patients from Greece and Cyprus. A self-administered questionnaire developed in collaboration with the Greek Society of Migraine Patients was used. RESULTS: Questionnaires were collected from 617 migraine patients. Efficacy was preferred over safety as the single most important parameter, both in acute and preventive treatment. When analyzing single outcomes, patients prioritized a complete pain remission at 1-hour post-dose for acute therapies. Regarding migraine prevention, a 75% reduction in frequency, intensity of pain, accompanying symptoms and acute medication intake were considered as most important. Conversely, outcomes routinely used in clinical trials, namely complete or partial pain remission at 2-hours post-dose for acute treatment and 50% or 30% reduction in migraine frequency for prevention, were not deemed particularly relevant. Tablet formulation was mostly preferred, both in acute and preventive treatment. Conclusion: Listening to patients' needs may add a piece of the puzzle that is generally missing in clinical practice and often explains the lack of adherence in both acute and preventative anti-migraine therapies.

Buried Bumper Syndrome: A common complication of levodopa intestinal infusion for Parkinson disease.

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) is required for Levodopa/Carbidopa Intestinal Gel (LCIG) delivery in patients with advanced Parkinson's disease (PD) as well as for enteral feeding in a variety of neurological disorders. Buried Bumper Syndrome (BBS) is a serious complication of PEG. The frequency of BBS in patients receiving LCIG treatment has never been reported. OBJECTIVES: To compare the frequency of BBS in patients on LCIG treatment or on enteral feeding over the past 12 years and identify possible risk factors. METHODS: We reviewed prospectively recorded data from 2009 to 2020 on two case-series: LCIG-treated PD patients and non-PD patients on enteral nutrition. We identified all BBS incidences. Patients' characteristics, clinical manifestations, BBS management, possible risk factors and outcomes were analyzed. RESULTS: During the 12 years, 35 PD patients underwent PEG insertion for LCIG infusion, and 123 non-PD patients for nutritional support. There were eight cases of BBS in six PD patients (17.1%). Six of them were effectively managed without treatment discontinuation. Of the enteral feeding patients, only one developed BBS (0.8%) (p < 0.001). We identified inappropriate PEG site aftercare, weight gain, early onset PD, longer survival, treatment duration, dementia and PEG system design as potential risk factors for BBS development. CONCLUSIONS: BBS occurs more frequently in LCIG patients than in patients receiving enteral feeding. If detected early, it can be successfully managed, and serious sequalae or treatment discontinuation can be avoided. Regular endoscopic follow-up visits of LCIG-treated patients and increased awareness in patients and clinicians are recommended.

Advanced technologies and novel neurostimulation targets in trigeminal autonomic cephalalgias.

The trigeminal autonomic cephalalgias (TACs) are a group of rare but disabling primary headache disorders. Their management is challenging, since only few effective treatments are available and high doses may be required to control the headache, compromising patients' adherence to treatments. A significant minority of patients, who fail to respond to or tolerate established treatments, are left with enormous level of disability and disruption to their quality of life. A growing body of evidence demonstrates the efficacy of central and peripheral neuromodulation approaches for management of patients with refractory TACs. In view of the potential risks related to deep brain stimulation of the posterior hypothalamic region, occipital nerve stimulation is currently considered the first treatment option for refractory chronic TACs. However, in view of the presence of paraesthesia induced by the stimulator, no robust controlled trials have been possible so far. Additionally, the equipment used for occipital nerve stimulation is not designed specifically for peripheral nerve stimulation, thus a significant proportion of patients experience device-related complications that often require surgical revisions. To overcome these issues, new neurostimulation technologies using less invasive or non-invasive approaches and modulating different neuroanatomical targets have been recently studied.
