Efficacy and safety of cutting therapy in the treatment of migraine: A protocol for systematic review and meta-analysis

BACKGROUND

Migraine is a chronic paroxysmal neurovascular disease in which pain on one or both sides of the head is the main manifestation and is accompanied by other neurological manifestations. Clinical practice has shown that cutting therapy as a complementary alternative medicine can play a role in relieving migraine attacks. However, there is no consensus on the efficacy of cutting treatment in the treatment of migraine. The aim of this study was to conduct a meta-analysis to systematically evaluate the efficacy and safety of cutting therapy in the treatment of migraine.

METHODS

First, databases were searched for relevant literature. The main databases we searched were PubMed, the Web of Science, MEDLINE, Embase, Cochrane Library, the Chinese National Knowledge Infrastructure, the Chinese Science Journal Database, Wanfang Data, and the Chinese Biomedical Literature Database. The keywords searched were "cutting treatment," " traditional Chinese medicine cutting treatment," and "migraine." The search was conducted from inception to November 2021. Second, 2 reviewers independently completed the process of study selection, data extraction, risk of bias assessment and data synthesis in strict accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses Protocols statement guidelines. Finally, we will use Review Manager Version 5.3 software for meta-analysis.

RESULTS

This study will provide the most recent evidence related to the treatment of migraine by cutting therapy.

CONCLUSION

The results of this systematic evaluation will provide an objective evidence-based framework for judging the effectiveness and safety of cutting therapy in the treatment of migraine.

Kopfschmerz bei Parietal- und Okzipitallappenepilepsien

Epilepsiepatienten leiden überdurchschnittlich häufig unter Kopfschmerzen. Dies gilt insbesondere für Patienten mit idiopathisch generalisierten und parietookzipitalen Epilepsien. Die Häufigkeit des gemeinsamen Auftretens von Kopfschmerzen und Epilepsie überschreitet dabei die rechnerische Koinzidenz, sodass von einer Komorbidität beider Syndrome auszugehen ist. Bestärkt wird diese Hypothese durch überlappende genetische Veränderungen sowie gemeinsame pathophysiologische Mechanismen. Bis zu 62 % der Patienten mit z. B. Parietal- und Okzipitallappenepilepsie (POLE) geben Kopfschmerzen an. Diese treten v. a. nach dem Anfall (postiktal) auf und manifestieren sich am häufigsten als Migräne-ähnlicher Kopfschmerz oder Spannungskopfschmerz. Seltener kommt es zu Kopfschmerzen vor (periiktal), während (iktal) oder zwischen (interiktal) epileptischen Anfällen. Bei transienten neurologischen Ausfallsymptomen mit begleitenden Kopfschmerzen ist differenzialdiagnostisch neben der Migräne an vaskuläre Ereignisse wie Synkopen oder eine transiente ischämische Attacke zu denken.

[Tips for taking the medical history in patients with syncope]

Transient loss of consciousness represents one of the most frequent reasons for patients to present in the emergency room. Already at the very beginning, the diagnostic work-up is faced with fundamental questions: (1) Was it really a loss of consciousness? (2) Which department (neurology, cardiology, or others) should check the patient? (3) Is an in-hospital diagnostic work-up required? These questions can be answered from a meticulous patient history which needs to be adjusted to the individual case but also has to systematically go through a list of questions. Patient history has to clarify whether syncope was present. Nonsyncopal events such as falls, transient global amnesia, epilepsy, psychogenic pseudosyncope, transient ischemic attack and drop attacks should be distinguished. In a second step, the four groups of causes of syncope can be assessed. Neurocardiogenic reflex syncope usually occurs with typical prodromes in typical situations in (younger) patients without heart disease. Orthostasis always occurs in upright position, typically associated with standing up and in patients treated with antihypertensive drugs. Arrhythmogenic syncope frequently shows an abrupt onset without prodromes, associated with injury and with palpitations or fast heart beat before the attack, in older patients frequently associated with known heart disease, in young patients without heart disease frequently with a family history positive for arrhythmias or sudden cardiac death. A positive history of structural cardiovascular disease should be considered as a cause of syncope, particularly if it occurs during exercise or in supine position, or is associated with chest pain or dyspnea. This review summarizes the most important questions that can elucidate the cause of syncope.
