Shifts in Diagnostic Testing for Headache in the Emergency Department, 2015 to 2021.

Importance: Subarachnoid hemorrhage is typically diagnosed by noncontrast head computed tomography (CT); lumbar puncture is recommended if computed tomography is nondiagnostic, although CT cerebral angiography has been promoted as an alternative to lumbar puncture in this diagnostic pathway. The outcomes of this debate in practice have not been studied. Objective: To determine whether CT cerebral angiography use has increased in lieu of lumbar puncture among emergency department (ED) patients with headache, with an increase in unruptured intracranial aneurysm detection. Design, Setting, and Participants: This retrospective cohort study took place in 21 community EDs of an integrated health care system in Northern California between 2015 and 2021. Participants were adult (aged >17 years) health plan members with a chief concern of headache. Exclusions were prior diagnoses of subarachnoid hemorrhage, unruptured intracranial aneurysm, cerebral arteriovenous malformation, or cerebrospinal fluid shunt. Data were analyzed from October to November 2023. Exposures: CT cerebral angiography and/or lumbar puncture during the ED encounter. Main Outcomes and Measures: Primary and secondary outcomes were 14-day and 90-day unruptured intracranial aneurysm detection, respectively. Safety outcomes were missed diagnoses of subarachnoid hemorrhage or bacterial meningitis. The annual incidence of unruptured intracranial aneurysm detection was normalized to the incidence of subarachnoid hemorrhage (UIA:SAH ratio). Average annualized percentage changes were quantified using joinpoint regression analysis. Results: Among 198 109 included ED encounters, the mean (SD) age was 47.5 (18.4) years; 140 001 patients (70.7%) were female; 29 035 (14.7%) were Black or African American, 59 896 (30.2%) were Hispanic or Latino, and 75 602 (38.2%) were White. Per year, CT cerebral angiography use increased (18.8%; 95% CI, 17.7% to 20.3%) and lumbar punctures decreased (-11.1%; 95% CI, -12.0% to -10.4%), with a corresponding increase in the 14-day UIA:SAH ratio (3.5%; 95% CI, 0.9% to 7.4%). Overall, computed tomography cerebral angiography use increased 6-fold relative to lumbar puncture, with a 33% increase in the detection of UIA. Results were similar at 90 days and robust to sensitivity analyses. Subarachnoid hemorrhage (1004 cases) and bacterial meningitis (118 cases) were misdiagnosed in 5% and 18% of cases, respectively, with no annual trends (P = .34; z1003 = .95 and P = .74; z117 = -.34, respectively). Conclusions and Relevance: In this cohort study of ED patients with headache, increases in CT cerebral angiography use were associated with fewer lumbar punctures and higher detection of unruptured intracranial aneurysms, with no significant change in missed diagnoses of subarachnoid hemorrhage or bacterial meningitis. While this shift in diagnostic strategy appeared safe in the short-term, the long-term consequences remain unclear.

Daith piercing: Revisited from the perspective of auricular acupuncture systems. A narrative review.

BACKGROUND: Daith piercing is a special ear-piercing method that punctures the crus of the helix. The penetrated site at the ear's innermost point is assumed to stimulate a pressure point associated with the vagus nerve. It has been reported that the pierced spot relieves migraine and tension-type headaches by activating vagal afferents, leading to the inhibition of neurons in the caudal trigeminal nucleus via the nucleus tractus solitarii. OBJECTIVE: The objective of this narrative literature review is to summarize the current state of knowledge concerning daith piercing for the treatment of migraine and tension-type headaches from the perspectives of the Chinese and Western auricular systems. METHODS: PubMed and China National Knowledge Infrastructure databases were searched using the keywords "daith piercing," "auricular points," "headache," and "acupuncture" from database inception to September 1, 2023. Only studies on humans were eligible; otherwise, no further restrictions were applied to the study designs, type of headache, or patient population of the identified articles. Bibliographies of all eligible studies were screened for further eligible studies. The main outcome of interest was a quantitative measure of pain relief by daith piercing. Secondary outcomes were relapse time of headache and further outcomes related to daith piercing, if available. RESULTS: From a total of 186 identified articles, one retrospective study and three case reports fulfilled the inclusion criteria. No clinical trial was identified. The obtained studies describe patients experiencing chronic headaches undergoing daith piercing without changing or reducing their usual medication. In all case studies and the retrospective study, patients reported substantial reductions in pain immediately after daith piercing; however, headache symptoms recurred several weeks to months thereafter. From the perspective of the Chinese and Western auricular systems, no sufficient explanation for the described treatment effect of daith piercing was found. CONCLUSION: The available literature, combined with the reported recurrence of pain as well as the associated side effects of daith piercing, indicate that current evidence does not support daith piercing for the treatment of migraine, tension-type headaches, or other headache disorders. PLAIN LANGUAGE SUMMARY: This paper summarizes what we know about Daith piercing (DP) for chronic migraine and tension-type headache and discusses how DP might work. Current evidence does not support DP as an effective treatment of chronic migraine and tension-type headache. These findings might assist clinicians in discussing this subject with patients as well as guide future research.

Comprehensive neurosurgical treatment of right occipital arteriovenous malformation with advanced angiographic techniques.

/Summary. A 39-year-old female with a notable medical history of smoking and a familial predisposition to unruptured aneurysms presented with clinical symptoms of intermittent right-sided headaches, flashes of light, and pulsatile tinnitus in the right ear. Diagnostic evaluations, including advanced angiographic techniques, identified a right occipital arteriovenous malformation (AVM). The angiogram revealed significant venous flow voids, emphasizing the need for a comprehensive treatment approach. The Spetzler-Martin grading system classified the AVM as Grade 2, indicating a moderate risk profile. A strategic decision was made to undergo partial embolization of two primary arterial feeders from the right posterior cerebral artery (PCA). Subsequent post-embolization angiograms confirmed a marked reduction in arteriovenous shunting, validating the efficacy of the intervention. The surgical approach encompassed an occipital craniotomy, meticulous subarachnoid dissection, and intraoperative angiography to ensure complete resection. Post-operative assessments showcased a successful and complete AVM resection. The patient experienced a brief, transient headache post-surgery, which resolved on its own. She was discharged on the third post-operative day and has since reintegrated into her professional life. However, she reported a minor visual field deficit, which, while noticeable, did not impede her daily activities. This case underscores the importance of a holistic, patient-centric approach in managing AVMs [1-3]. It challenges the conventional wisdom from the ARUBA trial, advocating for a more nuanced, individualized treatment paradigm, especially for young patients with low-grade AVMs [4].

Effectiveness and safety of scalp acupuncture for treating migraine: A systematic review and meta-analysis.

OBJECTIVE: Migraine is a prevalent and disabling neurological disorder affecting a significant proportion of the global population. Although medications are the primary treatment option, their efficacy remains unclear. Thus, alternative therapies such as scalp acupuncture have gained momentum; however, evidence for the effectiveness of scalp acupuncture remains insufficient. Therefore, this review provides evidence regarding the effectiveness and safety of scalp acupuncture for the treatment of migraines. DESIGN: PubMed, EMBASE, CENTRAL, Oriental Medicine Advanced Searching Integrated System, Korean Studies Information Service System, Korean Medical Database, NDSL, Citation Information by NII, and China National Knowledge Infrastructure were searched from their inception to September 2022 to identify randomised controlled trials (RCTs) without language restrictions. Data were collected and analysed independently by two reviewers. The RoB 2.0 tool was used to evaluate the risk of bias, and a meta-analysis was conducted using RevMan software (V5.4). SETTING: Eight RCTs including 874 patients were selected. RESULTS: Scalp acupuncture had a higher total effective rate (relative risk [RR]:1.24; 95% confidence interval [CI]:1.08-1.43; P < 0.01) than that of ordinary acupuncture. The headache index decreased significantly (standardised mean differences [SMD]:-1.27; 95% CI:-2.06 to -0.48; P < 0.01), and the total effective rate was higher (RR:1.20; 95% CI:1.06-1.37; P < 0.01) with scalp acupuncture than with medications. However, evidence supporting the effectiveness of scalp acupuncture was not robust. No adverse events were reported. CONCLUSION: Scalp acupuncture appears to be more effective than other treatments for migraines. However, their safety remains uncertain. PROSPERO REGISTRATION NUMBER: CRD42022348879.

Using Battlefield Acupuncture (BFA or Auricular Acupuncture) to Treat Primary Headaches in the Emergency Department.

Patients with headaches who present to the emergency department (ED) need prompt pain management. Headaches are a common complaint in the ED. Urgent evaluation is critical to assess for life-threatening headache causes. Once the causes of secondary headaches are ruled out, various pain control modalities for primary headaches can be used. This article and case will illustrate the treatment of primary headaches using battlefield acupuncture (BFA) as it is effective, minimally invasive, and has minimal undesired side effects or interactions. BFA will continue to work after the patient has left the ED. Average pain relief can be 4-7 days but varies depending on etiology. BFA presents an opportunity to minimize costly resource overutilization while still providing an option for quick, safe, and effective pain control. The article will also briefly mention some crucial headache assessments (detailed education on headache assessment should be done separately by the reader).

Remission of Dowager's hump by manipulative correction of spinal alignment: a case report.

Dowager's hump is described as excessive kyphotic curvature in the thoracic spine with a Cobb angle of more than 40 degrees. This case report presents a 61 years old female office clerk who experienced headaches and neck pain for 3 years that extended into her right shoulder and upper chest. She consulted her primary care physician two months before seeing the chiropractor when the neck pain worsened. A diagnosis of cervicalgia related to osteoarthritis was made based on cervical and thoracic X-ray findings. The patient received non-steroid anti-inflammatory drugs (celecoxib and etoricoxib) and stretching exercises at home. At the onset of chiropractic care, radiographs showed loss of cervical lordosis, narrowing at the C4-5, C5-C6, and C6-7 intervertebral disc space with marginal osteophytes. Based on these findings, a working diagnosis of cervicogenic headache was established. After treatment for 9 months, the patient showed improvement in symptoms and function from cervical curve radiographic change and dextro-convexity of the thoracic spine. Avoiding forward head flexion and maintaining correct posture in daily activities will be key mechanisms to prevent the reoccurrence of Dowager's hump. The improvement of symptoms following chiropractic therapy has been shown to correlate with radiographic markers of spinal realignment.

Acupuncture for acute migraine attacks in adults: a systematic review and meta-analysis.

Objective To evaluate the effect and safety of acupuncture for acute migraine attacks in adults. DESIGN AND SETTING: We searched PubMed, MEDLINE(OVID), Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Chinese Science and Technology Periodical Database and Wanfang database from inception to 15 July 2022. We included randomised controlled trials (RCTs) published in Chinese and English comparing acupuncture alone against sham acupuncture/placebo/no treatment/pharmacological therapy or comparing acupuncture plus pharmacological therapy against the same pharmacological therapy. Results were reported as risk ratios (RRs) for dichotomous outcomes or mean differences (MDs) for continuous outcomes, with 95% CIs. Risk of bias was assessed with the Cochrane tool and the certainty of the evidence (CoE) with GRADE. : Main outcome measures : a) The rate of headache freedom (pain score=0) at 2h after the treatment; b) the rate of headache relief (at least 50% reduction of pain score); c) headache intensity at 2h after the treatment(study data from scales measuring pain intensity, including visual analogue scale, numerical rating scale) d) the improvement of headache intensity at 2h after the treatment; e) the improvement values of migraine-associated symptoms; f) adverse events. RESULTS: We included 21 RCTs from 15 studies with 1926 participants comparing acupuncture against other interventions. Comparing to sham acupuncture or placebo, acupuncture may result in an increase in the rate of headache freedom (RR 6.03, 95% CI 1.62 to 22.41, 180 participants, 2 studies, I2=0%, low CoE) and the improvement of headache intensity (MD 0.51, 95% CI 0.16 to 0.85, 375 participants, 5 studies, I2=13%, moderate CoE) at 2 hours after treatment. It also may result on a higher rate of headache relief (RR 2.29, 95% CI 1.16 to 4.49, 179 participants,3 studies, I2=74%, very low CoE) and greater improvement of migraine-associated symptoms (MD 0.97, 95% CI 0.33 to 1.61, 90 participants, 2 studies, I2=0%, very low CoE) at 2 hours after treatment but the evidence is very uncertain. Meanwhile the analysis indicates acupuncture probably results in little to no difference in adverse events compared with sham acupuncture (RR 1.53, 95% CI 0.82 to 2.87, 884 participants, 10 studies, I2=0%, moderate CoE). In acupuncture plus pharmacological intervention versus the same pharmacological intervention, acupuncture plus pharmacological therapy may result in little to no difference in the rate of headache freedom (RR 1.55, 95% CI 0.99 to 2.42, 94 participants, 2 studies, I2=0%, low CoE), the rate of headache relief (RR 1.20, 95% CI 0.91 to 1.57, 94 participants, 2 studies, I2=0%, low CoE) at 2 hours after treatment and adverse events(RR 1.48, 95% CI 0.25 to 8.92, 94 participants, 2 studies, I2=0%, low CoE). However, it may result in a reduction in headache intensity (MD -1.05, 95% CI -1.49 to -0.62, 129 participants, 2 studies, I2=0%, low CoE) and an increase in the improvement of headache intensity (MD 1.18, 95% CI 0.41 to 1.95, 94 participants, 2 studies, I2=0%, low CoE) at 2 hours after treatment compared with pharmacological therapy only. In comparison to pharmacological intervention, acupuncture may result in little to no difference in the rate of headache freedom (RR 0.95, 95% CI 0.59 to 1.52, 294 participants, 4 studies, I2=22%, low CoE), the rate of headache relief (RR 0.95, 95% CI 0.80 to 1.14, 206 participants, 3 studies. I2=0%, low CoE) at 2 hours and adverse events (RR 0.65, 95% CI 0.35 to 1.22, 294 participants, 4 studies, I2=0%, low CoE) after treatment. The evidence is very uncertain about the effect of acupuncture on the headache intensity (MD -0.07, 95% CI -1.11 to 0.98, 641 participants, 5 studies, I2=98%, very low CoE) and the improvement of headache intensity (MD -0.32, 95% CI -1.07 to 0.42, 95 participants, 2 studies, I2=0%, very low CoE) at 2 hours after treatment compared with pharmacological intervention. CONCLUSION: The body of evidence suggests that acupuncture may be more effective than sham acupuncture in the treatment of migraine. Acupuncture may also be as effective as pharmacological therapy. However, the certainty evidence across outcomes was low to very low and new high-quality studies can provide more clarity. PROSPERO REGISTRATION NUMBER: CRD42014013352.

The cervical spine in tension type headache.

INTRODUCTION: The concept that headaches may originate in the cervical spine has been discussed over decades and is still a matter of debate. The cervical spine has been traditionally linked to cervicogenic headache; however, current evidence supports the presence of cervical musculoskeletal dysfunctions also in tension-type headache. PURPOSE: This position paper discusses the most updated clinical and evidence-based data about the cervical spine in tension-type headache. IMPLICATIONS: Subjects with tension-type headache exhibit concomitant neck pain, cervical spine sensitivity, forward head posture, limited cervical range of motion, positive flexion-rotation test and also cervical motor control disturbances. In addition, the referred pain elicited by manual examination of the upper cervical joints and muscle trigger points reproduces the pain pattern in tension-type headache. Current data supports that the cervical spine can be also involved in tension-type headache, and not just in cervicogenic headache. Several physical therapies including upper cervical spine mobilization or manipulation, soft tissue interventions (including dry needling) and exercises targeting the cervical spine are proposed for managing tension-type headache; however, the effectiveness of these interventions depends on a proper clinical reasoning since not all will be equally effective for all individuals with tension-type headache. Based on current evidence, we propose to use the terms cervical "component" and cervical "source" when discussing about headache. In such a scenario, in cervicogenic headache the neck can be the cause (source) of the headache whereas in tension-type headache the neck will have a component on the pain pattern, but it will be not the cause since it is a primary headache.

Preventive treatment of refractory chronic cluster headache: systematic review and meta-analysis.

BACKGROUND: Preventive treatment for refractory chronic cluster headache (rCCH) is challenging and many therapies have been tried. OBJECTIVE: To study what could be considered the therapy of choice in rCCH through a systematic review and meta-analysis. METHODS: This review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The protocol was registered in PROSPERO (ID CRD42021290983). A systematic search was performed in MEDLINE, Embase, Cochrane, clinicaltrials.gov, and the WHO's-International-Clinical-Trials-Registry-Platform. Studies on the preventive treatment for rCCH as defined by the European Headache Federation consensus statement were included. A meta-analysis of the pooled response rate was conducted for the different therapies. RESULTS: Of 336 results, 45 were eligible for inclusion. Most articles studied the effect of neuromodulation as a preventive treatment for rCCH. The most studied neuromodulation technique was occipital nerve stimulation (ONS), with a pooled response rate in the meta-analysis of 57.3% (95% CI 0.481-0.665). Deep brain stimulation (DBS) was the second most studied treatment with a pooled response rate of 77.0% (95% CI 0.594-0.957). DBS results were more heterogeneous than ONS, which could be related to the different stimulation targets in DBS studies, and reported more serious adverse events than in ONS studies. The remaining therapies (anti-CGRP pathway drugs, warfarin, ketamine-magnesium infusions, serial occipital nerve blocks, clomiphene, onabotulinum toxin A, ketogenic diet, sphenopalatine ganglion radiofrequency or stimulation, vagus nerve stimulation, percutaneous bioelectric current stimulation, upper cervical cord stimulation, and vidian neurectomy) present weaker results or have less quality of evidence. CONCLUSIONS: The results of this systematic review and meta-analysis suggest that ONS could be the first therapeutic strategy for patients with rCCH based on the current evidence.

Natural Language Processing for Improved Characterization of COVID-19 Symptoms: Observational Study of 350,000 Patients in a Large Integrated Health Care System.

BACKGROUND: Natural language processing (NLP) of unstructured text from electronic medical records (EMR) can improve the characterization of COVID-19 signs and symptoms, but large-scale studies demonstrating the real-world application and validation of NLP for this purpose are limited. OBJECTIVE: The aim of this paper is to assess the contribution of NLP when identifying COVID-19 signs and symptoms from EMR. METHODS: This study was conducted in Kaiser Permanente Southern California, a large integrated health care system using data from all patients with positive SARS-CoV-2 laboratory tests from March 2020 to May 2021. An NLP algorithm was developed to extract free text from EMR on 12 established signs and symptoms of COVID-19, including fever, cough, headache, fatigue, dyspnea, chills, sore throat, myalgia, anosmia, diarrhea, vomiting or nausea, and abdominal pain. The proportion of patients reporting each symptom and the corresponding onset dates were described before and after supplementing structured EMR data with NLP-extracted signs and symptoms. A random sample of 100 chart-reviewed and adjudicated SARS-CoV-2-positive cases were used to validate the algorithm performance. RESULTS: A total of 359,938 patients (mean age 40.4 [SD 19.2] years; 191,630/359,938, 53% female) with confirmed SARS-CoV-2 infection were identified over the study period. The most common signs and symptoms identified through NLP-supplemented analyses were cough (220,631/359,938, 61%), fever (185,618/359,938, 52%), myalgia (153,042/359,938, 43%), and headache (144,705/359,938, 40%). The NLP algorithm identified an additional 55,568 (15%) symptomatic cases that were previously defined as asymptomatic using structured data alone. The proportion of additional cases with each selected symptom identified in NLP-supplemented analysis varied across the selected symptoms, from 29% (63,742/220,631) of all records for cough to 64% (38,884/60,865) of all records with nausea or vomiting. Of the 295,305 symptomatic patients, the median time from symptom onset to testing was 3 days using structured data alone, whereas the NLP algorithm identified signs or symptoms approximately 1 day earlier. When validated against chart-reviewed cases, the NLP algorithm successfully identified signs and symptoms with consistently high sensitivity (ranging from 87% to 100%) and specificity (94% to 100%). CONCLUSIONS: These findings demonstrate that NLP can identify and characterize a broad set of COVID-19 signs and symptoms from unstructured EMR data with enhanced detail and timeliness compared with structured data alone.

Neck Pain and Headache After Pinealectomy: Improvement with Multimodal Chiropractic Therapies.

BACKGROUND Pineal gland tumors are rare central nervous system tumors, and while neck pain and headaches may be common among those who have had these tumors removed, there is little research regarding management of these symptoms. CASE REPORT A 45-year-old man with a history of pineal germinoma treated with pinealectomy, chemotherapy, radiation therapy, and ventriculoperitoneal shunt placement at age 21 presented with chronic neck pain and headaches, which initially improved following his surgery and concurrent therapies, yet progressively worsened over the following years. He required thyroid and testosterone medication because of radiation-induced hypopituitarism, yet was employed, and until recently, active with playing tennis. He had previously seen his primary care provider, orthopedist, and neurologist, and had been cleared of severe pathology via brain magnetic resonance imaging and was referred to the chiropractor. On examination, the patient had severely limited passive cervical spine range of motion, yet hat no neurologic deficits, and radiographs showed mild cervical spondylosis and cervicothoracic scoliosis. His history and presentation were suggestive of radiation-induced fibrosis. The patient's neck pain, headaches, and quality of life improved with multimodal treatments including spinal and soft-tissue manipulation, stretches, and yoga. CONCLUSIONS This case illustrates long-term sequelae of a pineal gland tumor and its treatment, including neck pain and headache, and improvement with multimodal chiropractic therapies. Despite the success in this case, these results are not broadly generalizable. Further research is needed to understand the natural history of symptoms and effectiveness of multimodal therapies among patients who have had pineal tumor surgery.

Long COVID: Rapid Evidence Review.

Postacute sequelae of COVID-19, also known as long COVID, affects approximately 10% to 30% of the hundreds of millions of people who have had acute COVID-19. The Centers for Disease Control and Prevention defines long COVID as the presence of new, returning, or ongoing symptoms associated with acute COVID-19 that persist beyond 28 days. The diagnosis of long COVID can be based on a previous clinical diagnosis of COVID-19 and does not require a prior positive polymerase chain reaction or antigen test result to confirm infection. Patients with long COVID report a broad range of symptoms, including abdominal pain, anosmia, chest pain, cognitive impairment (brain fog), dizziness, dyspnea, fatigue, headache, insomnia, mood changes, palpitations, paresthesias, and postexertional malaise. The presentation is variable, and symptoms can fluctuate or persist and relapse and remit. The diagnostic approach is to differentiate long COVID from acute sequelae of COVID-19, previous comorbidities, unmasking of preexisting health conditions, reinfections, new acute concerns, and complications of prolonged illness, hospitalization, or isolation. Many presenting symptoms of long COVID are commonly seen in a primary care practice, and management can be improved by using established treatment paradigms and supportive care. Although several medications have been suggested for the treatment of fatigue related to long COVID, the evidence for their use is currently lacking. Holistic treatment strategies for long COVID include discussion of pacing and energy conservation; individualized, symptom-guided, phased return to activity programs; maintaining adequate hydration and a healthy diet; and treatment of underlying medical conditions.

Chiari Malformation Presenting as Headaches Associated with Laughter.

Presentation We describe the case of a 5 year old boy, referred to our outpatient department with a one year history of headaches associated with laughter. Diagnosis Investigation with MRI Brain revealed Chiari Type 1 Malformation (CM-1), with cerebellar tonsillar descent of 19mm below the foramen magnum. Treatment He is being managed conservatively with serial neuroimaging and symptom monitoring. Discussion CM-1 is a hindbrain malformation characterised by ≥5mm herniation of the cerebellar tonsils.1,2 It is diagnosed radiographically, and is increasingly being detected incidentally.3,4 The natural history of asymptomatic patients is usually to remain asymptomatic, and symptomatic patients often show symptom improvement, particularly in paediatric populations.3,5 Neurosurgical interventions may be offered based on symptoms and radiographic findings, but carries a complication rate of 8.2%.6.

Neck pain and Headache Complicated by Persistent Syringomyelia After Foramen Magnum Decompression for Chiari I Malformation: Improvement with Multimodal Chiropractic Therapies.

BACKGROUND Patients with Arnold-Chiari Malformation I (CM-I) treated with foramen magnum decompression (FMD) can have ongoing neck pain, headaches, and other symptoms complicated by persistent syringomyelia, yet there is little research regarding treatment of these symptoms. CASE REPORT A 62-year-old woman with a history of residual syringomyelia following FMD and ventriculoperitoneal shunt for CM-I presented to a chiropractor with progressively worsening neck pain, occipital headache, upper extremity numbness and weakness, and gait abnormality, with a World Health Organization Quality of Life score (WHO-QOL) of 52%. Symptoms were improved by FMD 16 years prior, then progressively worsened, and had resisted other forms of treatment, including exercises, acupuncture, and medications. Examination by the chiropractor revealed upper extremity neurologic deficits, including grip strength. The chiropractor ordered whole spine magnetic resonance imaging, which demonstrated a persistent cervico-thoracic syrinx and findings of cervical spondylosis, and treated the patient using a multimodal approach, with gentle cervical spine mobilization, soft tissue manipulation, and core and finger muscle rehabilitative exercises. The patient responded positively, and at the 6-month follow-up her WHO-QOL score was 80%, her grip strength and forward head position had improved, and she was now able to eat using chopsticks. CONCLUSIONS This case highlights a patient with neck pain, headaches, and persistent syringomyelia after FMD for CM-I who improved following multimodal chiropractic and rehabilitative therapies. Given the limited, low-level evidence for these interventions in patients with persistent symptoms and syringomyelia after FMD, these therapies cannot be broadly recommended, yet could be considered on a case-by-case basis.

[New developments in headache management in 2022]. / Nouveautés dans la prise en charge des céphalées.

Headaches are one of the most common causes of consultation in primary care. Due to their polymorphic character and sometimes severe etiologies, it is very important to properly classify these symptoms and to look for possible associated signs of severity. It is with this objective that the international classification of headache delivered its 3rd version in 2018 with the ICHD-3. In addition, revised and validated severity criteria were also published in 2018 under the name SNNOOP10. At the same time, the concept of green flags which could allow to diagnose a primary headache without further investigations has emerged. In terms of treatment, the development of CGRP neuropeptide antagonists has allowed a major advance in the treatment of the severe forms of migraine. Finally, integrative medicine is taking on a central role.

Les céphalées sont l'un des motifs de consultation les plus courants en médecine de premier recours. En raison de leur caractère polymorphe et des étiologies potentiellement graves, il est essentiel de bien les classifier et de rechercher les signes de sévérité associés. C'est dans cet objectif que la classification internationale des céphalées a livré sa troisième version en 2018 (ICHD-3). Des critères de sévérité révisés et validés ont également été publiés en 2018 sous le nom de SNNOOP10. En parallèle, le concept de drapeaux verts, qui permettrait de retenir un diagnostic de céphalées primaires sans autres examens, a émergé. En termes de traitement, le développement d'antagonistes du neuropeptide CGRP (Calcitonin Gene-Related Peptide) a permis une avancée majeure dans le traitement des formes de migraine sévères. La médecine intégrative y prend par ailleurs une place centrale.

Classification of pediatric headache cases referred to a neurology department.

BACKGROUND: Headaches are very common in children. The patients often have mild symptoms, but on occasion may have severe, secondary headaches. The present study aimed to clarify the details of children with headaches seen at the outpatient clinic of a pediatric neurological department. METHODS: The present, retrospective observational study was conducted at a tertiary pediatric hospital in Japan and enrolled children referred to the neurology department outpatient clinic for headache between April 2018 and March 2021. RESULTS: In total, 113 cases of headache were examined; of these, 99 (87.6%) were primary headaches, one case (0.9%) was a secondary headache, and 13 (11.5%) were unclassified or unspecified. There were 46 cases (40.7%) of tension-type headache (TTH), both confirmed and suspected, 30 cases (26.5%) of migraine, and 23 cases (20.4%) of a combination of the TTH and migraine. One case of secondary headache was attributed to an infection. Arachnoid cysts were found in seven patients (7.8%). Acute drug treatments were administered to 93 patients (82.3%), with acetaminophen being the most common drug, followed by ibuprofen. Prophylactic drug treatments were administered to 39 patients (34.5%), with goreisan (a Chinese herbal medicine containing Alisma orientale, Poria cocos, Polyporus umbellatus, Atractylodes lancea, and Cinnamomum cassia) being the most common (41%). CONCLUSIONS: Few cases of secondary headache and none of emergency headache were diagnosed. The prevalence of arachnoid cysts was higher than in the general pediatric population, suggesting that arachnoid cysts might be associated with headache.

Acupuncture for menstrual migraine: a systematic review.

BACKGROUND AND OBJECTIVE: In clinical practice, the evidence of acupuncture used as a treatment for migraine without aura is employed interchangeably to guide treatment for menstrual migraine. However, its effect and safety are not substantiated. This study aimed to assess the efficacy of acupuncture on the frequency and pain intensity of menstrual migraine. METHODS: We searched PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI) and other two Chinese databases from their inception to 1 May 2019. This study included randomised controlled trials of women with menstrual migraine receiving acupuncture or a valid control. Two reviewers independently completed study selection, data extraction and risk of bias assessment. We combined data with a fixed-effect model in RevMan. Clinical outcomes included migraine frequency and duration, headache intensity, and adverse events. RESULTS: Thirteen studies with 826 subjects were included, 9 of which had data suitable for meta-analyses. Current evidence showed that acupuncture was not superior to sham acupuncture in reducing monthly migraine frequency and duration, average headache intensity, and analgesic use at completion of treatment or follow-up. Pooled data demonstrated a significant improvement in mean headache intensity in the acupuncture group compared with drugs. However, all studies were underpowered and associated with moderate to high risk of bias. No serious adverse event was related to acupuncture treatment. CONCLUSIONS: There is no convincing evidence to support the use of acupuncture in treating menstrual migraine. Acupuncture cannot yet be recommended to patients with menstrual migraine until more solid evidence is produced. TRIAL REGISTRATION NUMBER: CRD42019119337.

Acupuncture for migraine prophylaxis: A protocol for systematic review and Bayesian network meta-analysis.

BACKGROUND: Migraine causes health problems in 1 billion people worldwide and imposes a huge social burden. Acupuncture therapy has a good clinical effect in migraine prophylaxis and is recommended by authoritative journals. We plan to conduct a Bayesian network meta-analysis to compare the efficacies of different acupuncture therapies. METHODS: We will search PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure, VIP database for Chinese technical periodicals, Chinese biological medical database, WanFang Data, Cochrane register of controlled trials, Chinese Clinical Trial Register, and ClinicalTrials.gov from their inception to July 1, 2022, for randomized controlled trials that studied different acupuncture therapies and other therapies for the preventive treatment of migraine. Migraine episodes, migraine days, headache intensity, and adverse events will be counted as outcomes. Two reviewers will independently complete the study selection, data extraction, and risk of bias assessment of all filtered trials. Pairwise meta-analysis and Bayesian network meta-analysis will be performed (if applicable) through Review Manager 5.3 and the "gemtc" and "rjags" packages of the R software. Confidence in Network Meta-Analysis will be used to evaluate the quality and credibility of the evidence for each outcome. RESULTS: The protocol will compare the efficacies of different acupuncture therapies for migraine prophylaxis. CONCLUSION: This study aims to help clinicians develop an effective and safe treatment plan for migraine prophylaxis.

Effects of Aromatherapy with Lavender (Lavandula angustifolia MILL) on Post-Dural Puncture Headache: A Randomized Placebo-Controlled Trial.

Context: Lavender has been proposed as an analgesic agent for different types of headaches in complementary and alternative medicine. However, no documented trial has been performed to investigate the effects of lavender in managing post-dural puncture headache (PDPH). Objective: To evaluate the effects of aromatherapy using lavender essential oil in reducing the severity of PDPH. Design: Randomized, placebo-controlled clinical trial with parallel group design. Setting: Post-operative wards of Kamkar-Arab-Nia and Nekooei Hedayati Hospitals in Qom, Iran. Participants: Patients with PDPH caused by spinal anesthesia (n = 50). Intervention: Patients received 15-minute inhalations of either lavender oil or liquid paraffin as placebo, using the same protocol. Outcome Measures: The severity of headache was scored before (baseline) and five times after the intervention (immediately, 30, 60, 90, and 120 minutes after) using the visual analog scale. Also, dosage and frequency of the received Diclofenac and adverse effects of the intervention were recorded. Results: Both groups showed a reduction in headache scores post intervention. However, the headache scores between the groups was significantly different only immediately after the intervention in favor of lavender oil (difference: 1.60 ± 0.63, P = .015). Furthermore, it was observed that the mean changes of the headache scores compared to baseline were significant at each time interval in favor of the placebo group (P < .05), except immediately after the intervention. No significant difference was observed in diclofenac intake between groups (P = .440). Also, no adverse effects were found from the intervention. Conclusions: Aromatherapy with lavender oil was observed to reduce the severity of PDPH only immediately after the intervention, while only minimal effects were observed at successive time intervals. However, it is noted that the study was likely underpowered and further studies are recommended to better understand the effects of lavender oil on PDPH and compare its effects to other herbal products or pharmacological agents commonly used for managing headaches.
