Clinical observation of endoscopic skull base reconstruction with an anterolateral thigh free fascia flap

ObjectiveRadiation osteonecrosis of the skull base after radiotherapy for nasopharyngeal carcinoma is one of the most serious complications, affecting patient survival and quality of life. To date, surgical resection is the main treatment for radiation osteonecrosis. The repair after the operation is very important. Inappropriate repair or lack of repair can easily cause local infection that can even spread to the brain, aggravating osteonecrosis. This study aimed to verify the feasibility and safety of the anterolateral thigh free fascia flap in repairing large skull base defects. MethodsFrom June 2021 to July 2022, a total of 12 patients with a history of radiotherapy for nasopharyngeal carcinoma received surgical treatment at the Department of Otolaryngology Head & Neck Surgery, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine. All patients were diagnosed with radiation osteonecrosis of the skull base with large skull base defects. During the endoscopic operation, a free anterolateral thigh fascia flap was used to repair the skull base and complete vascular anastomosis reconstruction. The preoperative and postoperative pain scores were retrospectively analyzed, and the dynamic changes in endoscopic surgery sites were observed. ResultsThe 12 patients had a median age of 58 y, with 8 (66.7%) males and 4 (33.3%) females. The median headache score for the patients was 5 (4–7) before surgery. The patient's headache was significantly relieved postoperatively, with 11 patients having a score of 0 and one patient having a score of 1. The stench was completely resolved after the operation. There were no serious complications during the perioperative period or 12 months after the operation. ConclusionThe application of anterolateral thigh free fascia flap in skull base reconstruction is a safe and reliable reconstruction technique suitable for endoscopic surgical repair of large-scale skull base necrosis.

Clinical Implications of the Association between Respiratory and Gastrointestinal Disorders in Migraine and Non-Migraine Headache Patients.

Headaches, particularly migraine, are associated with gastrointestinal (GI) disorders. In addition to the gut-brain axis, the lung-brain axis is suspected to be involved in the relationship between pulmonary microbes and brain disorders. Therefore, we investigated possible associations of migraine and non-migraine headaches (nMH) with respiratory and GI disorders using the clinical data warehouse over 11 years. We compared data regarding GI and respiratory disorders, including asthma, bronchitis, and COPD, among patients with migraine, patients with nMH, and controls. In total, 22,444 patients with migraine, 117,956 patients with nMH, and 289,785 controls were identified. After adjustment for covariates and propensity score matching, the odds ratios (ORs) for asthma (1.35), gastroesophageal reflux disorder (1.55), gastritis (1.90), functional GI disorder (1.35), and irritable bowel syndrome (1.76) were significantly higher in patients with migraine than in controls (p = 0.000). The ORs for asthma (1.16) and bronchitis (1.33) were also significantly higher in patients with nMH than in controls (p = 0.0002). When the migraine group was compared with the nMH group, only the OR for GI disorders was statistically significant. Our findings suggest that migraine and nMH are associated with increased risks of GI and respiratory disorders.

Functional brainstem representations of the human trigeminal cervical complex.

The human in-vivo functional somatotopy of the three branches of the trigeminal (V1, V2, V3) and greater occipital nerve in brainstem and also in thalamus and insula is still not well understood. After preregistration (clinicaltrials.gov: NCT03999060), we mapped the functional representations of this trigemino-cervical complex non-invasively in 87 humans using high-resolution protocols for functional magnetic resonance imaging during painful electrical stimulation in two separate experiments. The imaging protocol and analysis was optimized for the lower brainstem and upper spinal cord, to identify activation of the spinal trigeminal nuclei. The stimulation protocol involved four electrodes which were positioned on the left side according to the three branches of the trigeminal nerve and the greater occipital nerve. The stimulation site was randomized and each site was repeated 10 times per session. The participants partook in three sessions resulting in 30 trials per stimulation site. We show a large overlap of peripheral dermatomes on brainstem representations and a somatotopic arrangement of the three branches of the trigeminal nerve along the perioral-periauricular axis and for the greater occipital nerve in brainstem below pons, as well as in thalamus, insula and cerebellum. The co-localization of greater occipital nerve with V1 along the lower part of brainstem is of particular interest since some headache patients profit from an anesthetic block of the greater occipital nerve. Our data provide anatomical evidence for a functional inter-inhibitory network between the trigeminal branches and greater occipital nerve in healthy humans as postulated in animal work. We further show that functional trigeminal representations intermingle perioral and periauricular facial dermatomes with individual branches of the trigeminal nerve in an onion shaped manner and overlap in a typical within-body-part somatotopic arrangement.Trial registration: clinicaltrials.gov: NCT03999060.

A Systematic Review of Anesthetic, Saline and Dry Needling Injections for Headache Patients

Objectives Earlier literature provided evidence of neck pain relief via cervical trigger point injections with anesthetic agents. However, recent evidence suggests that intramuscular or paraspinal cervical injections with local anesthetic may provide relief for various types of headaches and orofacial pain as well. The primary purpose of this systematic review was to determine whether a cohort of retrospective case studies and randomized controlled trials using paraspinal cervical or intramuscular anesthetic injections were associated with a decrease in headache and orofacial pain. Methods A systematic review of the literature was performed to observe the association between headache or orofacial pain relief and paraspinal cervical injections with various pain-relieving agents. Literature searches using the key terms “headaches”, “paraspinous cervical injections”, “neck/intramuscular injections” and “orofacial pain” were performed in PubMed, Google Scholar, and Scopus. We implemented the preferred reporting items for systematic reviews and meta-analyses (PRISMA) format for the systematic review. Results Initially, four hundred forty articles were located during the systematic review. Five total articles were selected for review and 435 were excluded because they did not meet search criteria. Another two relevant articles were found during manual searches within references of the systematic review. The seven studies included were retrospective case studies involving patients with headaches or orofacial pain who received paraspinal cervical or other intramuscular injections. A total of 841 patients’ data were tallied from the 7 articles and 683 of those patients received anesthetic injections. Significant pain relief due to intramuscular or paraspinal cervical injections was observed in 83.7% of the patients. Conclusion Our systematic review of association between headache or orofacial pain relief and paraspinal cervical injections with various pain-relieving agents demonstrated a frequency of headache and orofacial pain relief of 83.7%. Such a large percentage compared to a robust placebo study provides promising evidence that this treatment may have a therapeutic role in the management of headache and orofacial pain. Despite limitations faced in performing our systematic review, it seems quite clear that pain relief for these headache patients can be attributed to intramuscular anesthetic or dry needling injections. While larger prospective studies should be performed regarding specific location and anesthetic, our systematic review provides additional evidence that anesthetic intramuscular and dry needling injections provide pain relief intension-type headaches (TTH), migraine headaches, cervicogenic headache pain, and orofacial pain.

Relation and Treatment Approach of Migraine in Pregnancy and Breastfeeding.

Headaches are one of the most frequent reasons people visit the neurology department. In 2019, headache issues ranked as the 14th most common cause of disability-adjusted life years globally. According to the International Headache Society, migraine is a particular type of headache that is unilateral, frequently throbbing, associated with vertigo, and sensitive to light, sound, and head movement. A migraine has four stages: premonitory, aura, headache, and postdrome. Migraine is the type of discomfort that most frequently complicates the pregnancy. A migraine is more common in women than in men. Migraines are influenced by increased levels of estrogen during pregnancy and a sharp decrease in those levels during puerperium. Untreated migraine can result in premature labor, hypertension, and low birth weight babies. Menstrual-related events occurred more frequently in migraine sufferers than in non-migraine sufferers. We have explained the relation of sex hormones that triggermigraine. We have also reviewed the therapeutic approach, such as pharmacological and non-pharmacological approaches, for migraine in pregnancy and breastfeeding. A migraine episode during menstruation was slightly more severe and complicated than a headache that wasn't a migraine. Breastfeeding is not prohibited by migraines. The steady estrogen levels brought on by lactating women's lack of menstruation may function as a protective factor. In addition to any required drug therapy, nonpharmacological techniques should always be used as the first line of treatment. Preconception counseling is an essential part of providing headache patients with safe therapy during pregnancy. Supplemental estrogen should not be used by any women who have an aura or who are 35 years of age or older because there is inadequate proof to support any long-term adverse effects. Paracetamol is advised for use in acute therapy during pregnancy. Mothers who used acetaminophen during pregnancy are more likely to have children with hyperkinetic disorders and characteristics resembling attention-deficit/hyperactivity disorder. Menstrual migraine can be treated in a variety of ways, including acute therapy, non-pharmacological therapy, and preconception counseling. Similar tactics are used to treat migraines during pregnancy, but it's important to take the medications' safety rating into account. Migraines and menstrual problems go together. A safeguarding element is a constant estrogen level during pregnancy and breastfeeding. The preferred method of treatment for migraine is non-pharmacological therapy, followed by prenatal counseling. Sumatriptan and acetaminophen are both effective treatments for transient migraine attacks that occur during pregnancy or breastfeeding.

Headache diagnoses in patients with orofacial pain at a specialized pain center

Background. Headache and orofacial pain (OFP) are widespread at specialized pain centers. However, reliable data on their prevalence and co-occurrence are lacking, and prevalence of OFP in headache patients seems to be underestimated. The aim of this study was to evaluate the types of headache in patients with OFP and types of OFP in patients with headache.Methods. We enrolled patients presenting with headache and/or OFP. Patients were examined by an experienced headache and pain specialist who questioned the patients about the presence of OFP. Depression was assessed with the Beck Depression Inventory (BDI-II), anxiety – with the Beck Anxiety Inventory (BAI). Bruxism was evaluated based on subject self-report.Results. We recruited 310 patients: 177 (57%) patients with headache, 28 (9%) patients with OFP and 105 (34%) patients presenting with both types of pain. The prevalence of OFP in headache patients was 37.2%. Migraine was the most prevalent type of headache, while painful temporomandibular disorder (TMD) – the most prevalent form of OFP. Patients with PFP presented with a high prevalence of sleep and awake bruxism.Conclusion. Migraine and pain-related TMD are the most prevalent diagnoses in a specialized pain center. OKI and OKI ACT are soluble forms of ketoprofen and reach peak concentration in 15 minutes. This enables faster onset of action compared to conventional NSAIDs and better tolerability. OKI and OKI ACT are recommended in the acute treatment of migraine with comorbid painful TMD.

Prevalence, natural history and dynamic nature of chronic headache and medication overuse headache in Italy: The SPARTACUS study.

Chronic headaches and medication overuse headache are common and burdening conditions. No studies have evaluated the prevalence of chronic headache and medication overuse headache in an unselected Italian population. We performed a three-year cross-sectional and longitudinal population-based study to investigate prevalence, natural history, and prognostic factors of chronic headache. We delivered a self-administered questionnaire to 25,163 subjects. Chronic headache patients were interviewed by General Practitioners. After three years, medication overuse headache patients were invited to undergo a neurological evaluation at our Center. 16,577 individuals completed the questionnaire; 6878 (41,5%) were episodic headache sufferers and 636 (3.8%) were chronic headache subjects. 239 (1.4%) patients were acute medication over-users. All medication overuse headache patients had migraine or headache with migrainous features. At the three-year follow-up of 98 patients, we observed conversion to episodic headaches in 53 (54.1%) patients. 27 (50.9%) patients remitted spontaneously. We present the first prevalence data on chronic headache and medication overuse headache in an unselected Italian population and a high rate of spontaneous remission. These data support the interpretation of medication overuse headache as a specific migraine-related disorder that may reflect chronic migraine's dynamic nature, the need for more specific medication overuse headache diagnostic criteria, and highlight the priority of targeted public health policies.

A Computer Vision-Based Application for the Assessment of Head Posture: A Validation and Reliability Study

As its name implies, the forward head position (FHP) is when the head is further forward of the trunk than normal. This can cause neck and shoulder tension, as well as headaches. The craniovertebral angle (CVA) measured with 2D systems such as Kinovea software is often used to assess the FHP. Computer vision applications have proven to be reliable in different areas of daily life. The aim of this study is to analyze the test-retest and inter-rater reliability and the concurrent validity of a smartphone application based on computer vision for the measurement of the CVA. Methods: The CVAs of fourteen healthy volunteers, fourteen neck pain patients, and fourteen tension-type headache patients were assessed. The assessment was carried out twice, with a week of rest between sessions. Each examiner took a lateral photo in a standing position with the smartphone app based on computer vision. The test-retest reliability was calculated with the assessment of the CVA measured by the smartphone application, and the inter-rater reliability was also calculated. A third examiner assessed the CVA using 2D Kinovea software to calculate its concurrent validity. Results: The CVA in healthy volunteers was 54.65 (7.00); in patients with neck pain, 57.67 (5.72); and in patients with tension-type headaches, 54.63 (6.48). The test-retest reliability was excellent, showing an Intraclass Correlation Coefficient (ICC) of 0.92 (0.86–0.95) for the whole sample. The inter-rater reliability was excellent, with an ICC of 0.91 (0.84–0.95) for the whole sample. The standard error of the measurement with the app was stated as 1.83°, and the minimum detectable change was stated as 5.07°. The concurrent validity was high: r = 0.94, p < 0.001. Conclusion: The computer-based smartphone app showed excellent test-retest and inter-rater reliability and strong concurrent validity compared to Kinovea software for the measurement of CVA.

Cerebrovascular reactivity after functional activation of the Brain using Photic Stimulation in Migraine and Tension Type Headache: a transcranial doppler Ultrasonography Study

BackgroundPrevious studies in headache patients measured the cerebrovascular reactivity (CVR) in response to photic stimulation but they have yielded contradictory results. The purpose of study was to measure CVR of both migraine and chronic tension headache (TTH) patients in response to photic stimulation.MethodsThe study included 37 migraineurs and 24 chronic TTH patients compared with 50 age- and sex-matched healthy volunteers. Peak systolic, end diastolic, mean flow velocities and CVR (PSV, EDV, MFV, and CVR) were measured using TCD ultrasonography of the middle, anterior, posterior cerebral and vertebral arteries (MCA, ACA, PCA, and VA) before and after 100 s of 14 Hz photic stimulation.ResultsA three-way repeated measures ANOVA interaction with main factors of Vessels (MCA, ACA, PCA, VA), Time (pre-post photic) and Groups (migraine, TTH, and control group) revealed significant 3-way interactions for measures of PSV (P = 0.012) and MFV (P = 0.043). In the migraine patients there was significantly higher PSV, EDV, and MFV in the MCA, ACA, and PCA after photic stimulation compared with baseline. The CVR of the MCA was also significantly higher in migraineurs than controls. In the TTH group, there was significantly higher PSV, EDV, and MFV (P = 0.003, 0.012, 0.002 respectively) in the VA after photic stimulation than at baseline. The CVR was significantly higher in the VA of TTH patients than controls.ConclusionCompared with controls after photic stimulation, the higher CVR of the MCA in migraineurs and of the VA in TTH patients could be used as diagnostic tool to differentiate between the two types of headaches.

Cross-sectional, hospital-based analysis of headache types using ICHD-3 criteria in the Middle East, Asia, and Africa: the Head-MENAA study

BackgroundHeadaches are frequent neurological disorders that are yet to be unveiled and treated comprehensively worldwide. Bearing in mind that the distribution of headache subtypes in neurology clinics (NC) is essential for planning appropriate diagnostic and therapeutic approaches, the primary goals of this multi-centric study are to carry out inter-regional comparisons by using current diagnostic criteria with evaluations of neurologists to delineate headache burden.MethodsA cross-sectional study between April 1 and May 16, 2022 was conducted with the participation of 13 countries from the Middle East, Asia, and Africa. Patients were included in the study on a specific day each week during five consecutive weeks. All volunteers over the age of 18 and whose primary cause for admission was headache were examined. The patients admitted to NC or referred from emergency services/other services were evaluated by neurologists by means of the International Classification of Headache Disorders (ICHD-3) criteria.ResultsAmong the 13,794 patients encountered in NC, headache was the primary complaint in 30.04%. The headache patients’ mean age was 42.85 ± 14.89 (18–95 years), and 74.3% were female. According to the ICHD-3 criteria, 86.7% of the main group had primary headache disorders, 33.5% had secondary headaches, 4% had painful cranial neuropathies along with other facial and headaches, and 5.2% had headaches included in the appendix part showing some overlapping conditions. While the most common primary headache was migraine without aura (36.8%), the most common secondary headache was medication-overuse headache (MOH) (9.8%). Headaches attributed to COVID-19, its secondary complications, or vaccines continue to occur at rates of 1.2%-3.5% in current neurology practice. Pain severity was significantly lower in Ivory Coast and Sudan than in Türkiye, Turkish Republic of Northern Cyprus, Iran, Egypt, Senegal, Tatarstan, and Azerbaijan (p < 0.001).ConclusionsThe study showed that migraine is still the most common motive for admissions to NC in different regions. Furthermore, MOH, an avoidable disorder, is the most common secondary headache type and appears to be a significant problem in all regions. Remarkably, pain perception differs between regions, and pain intensity is lower in Africa than in other regions.

Reduced cardiovagal baroreflex sensitivity is associated with postural orthostatic tachycardia syndrome (POTS) and pain chronification in patients with headache.

Non-cephalgic symptoms including orthostatic intolerance, fatigue, and cognitive impairment, are common in patients with chronic headache disorders and may result from alterations in the autonomic nervous system. However, little is known about the function of autonomic reflexes, which regulate cardiovascular homeostasis and cerebral perfusion in patients with headache. Autonomic function testing data from patients with headache collected between January 2018 and April 2022 was retrospectively analyzed. Through review of EMR we determined headache pain chronicity and patient self-report of orthostatic intolerance, fatigue, and cognitive impairment. Composite Autonomic Severity Score (CASS), CASS subscale scores, and cardiovagal and adrenergic baroreflex sensitivities were used to quantify autonomic reflex dysfunction. Descriptive analyses (Mann-Whitney-U or χ2, as appropriate) determined associations between autonomic reflex dysfunction and POTS as well as chronic headache. Binomial logistic regression adjusted for age and sex. Spearman's rank correlation determined the association between the total CASS score and the number of painless symptoms reported by each participant. We identified 34 patients meeting inclusion criteria, of whom there were 16 (47.0%) with orthostatic intolerance, 17 (50.0%) with fatigue, 11 (32.4%) with cognitive complaints, and 11 (32.4%) with Postural Orthostatic Tachycardia Syndrome (POTS). The majority of participants had migraine (n = 24, 70.6%), were female (n = 23, 67.6%) and had a chronic (>15 headache days in a month) headache disorder (n = 26, 76.5%). Reduced cardiovagal baroreflex sensitivity (BRS-V) independently predicted chronic headache [aOR: 18.59 (1.16, 297.05), p = 0.039] and POTS [aOR: 5.78 (1.0, 32.5), p = 0.047]. The total CASS was correlated with the total number of non-painful features in the expected direction (r = 0.46, p = 0.007). Abnormal autonomic reflexes may play an important role in pain chronification and the development of POTS in patients with headache.

A machine learning approach to support triaging of primary versus secondary headache patients using complete blood count.

Headaches account for up to 4.5% of emergency department visits, where they present a significant diagnostic challenge. While primary headaches are benign, secondary headaches can be life-threatening. It is essential to rapidly differentiate between primary and secondary headaches as the latter require immediate diagnostic work-up. Current assessment relies on subjective measures; time constraints can result in overuse of diagnostic neuroimaging, prolonging diagnosis, and adding to economic burden. There is therefore an unmet need for a time- and cost-efficient, quantitative triaging tool to guide further diagnostic testing. Routine blood tests may provide important diagnostic and prognostic biomarkers indicating underlying headache causes. In this retrospective study (approved by the UK Medicines and Healthcare products Regulatory Agency Independent Scientific Advisory Committee for Clinical Practice Research Datalink (CPRD) research [20_000173]), UK CPRD real-world data from patients (n = 121,241) presenting with headache from 1993-2021 were used to generate a predictive model based on a machine learning (ML) approach for primary versus secondary headaches. A ML-based predictive model was constructed using two different methods (logistic regression and random forest) and the following predictors were evaluated: ten standard measurements of complete blood count (CBC) test, 19 ratios of the ten CBC test parameters, and patient demographic and clinical characteristics. The model's predictive performance was assessed using a set of cross-validated model performance metrics. The final predictive model showed modest predictive accuracy using the random forest method (balanced accuracy: 0.7405). The sensitivity, specificity, false negative rate (incorrect prediction of secondary headache as primary headache), and false positive rate (incorrect prediction of primary headache as secondary headache) were 58%, 90%, 10%, and 42%, respectively. The ML-based prediction model developed could provide a useful time- and cost-effective quantitative clinical tool to facilitate the triaging of patients presenting to the clinic with headache.

Cluster headache polygenetic risk and known functional variants of CYP3A4 are not associated with treatment response.

The response to cluster headache treatments has a high interindividual variation. To date, treatment response has only been assessed by a candidate gene approach and no investigations into metabolic pathways have been performed. Our aim was to investigate the association between the polygenetic risk of cluster headache and treatment response to first-line cluster headache treatments as well as known functional variants of CYP3A4 and the response to verapamil. Further, it was aimed to replicate previous single nucleotide polymorphisms found to be associated with treatment response in cluster headache and/or migraine. In, 508 cluster headache patients diagnosed according to the International Classification of Headache Disorders were genotyped and participated in a semi-structured interview to evaluate treatment response. Polygenetic risk scores were calculated by the effect retrieved from a meta-analysis of the latest two genome-wide association studies on cluster headache. Inferior treatment response to oxygen, triptans and verapamil is associated with chronicity of cluster headache were confirmed but no evidence was found that a response could be predicted by a high genetic risk of cluster headache. Likewise, verapamil response was not associated with functional variants of CYP3A4. No support of the genetic variants previously reported to be associated with treatment response to triptans or verapamil was found. The clinically relevant variation in treatment response for cluster headache was not influenced by genetic factors in the present study.

Transient headache and neurological deficits with cerebrospinal fluid lymphocytosis syndrome: A comprehensive systematic review of 93 patients from 57 studies.

Headache with neurologic deficits and cerebrospinal fluid lymphocytosis, previously also termed pseudomigraine with temporary neurologic symptoms and lymphocytic pleocytosis, is a self-limiting syndrome characterized by moderate to severe headache associated with focal neurological deficits occurring in the context of lymphocytosis in the cerebrospinal fluid. As a consequence of its rarity, data regarding headache with neurologic deficits and cerebrospinal fluid lymphocytosis is sparse. Therefore, we conducted this review to analyze data related to 93 patients of headache with neurologic deficits and cerebrospinal fluid lymphocytosis, to characterize their demographics, clinical manifestations, investigations and treatment options. We performed a systematic review of cases reported through PubMed and Google scholar database, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. Keywords used were 'Headache with Neurologic Deficits and cerebrospinal fluid lymphocytosis', 'Headache with neurologic deficits and cerebrospinal fluid lymphocytosis syndrome'. The quality of the included studies was assessed using the Joanna Briggs Institute Critical Appraisal Tool. We analyzed a total of 93 cases of headache with neurologic deficits and cerebrospinal fluid lymphocytosis with a mean age of 28.8 years at onset. Seventy patients (75.2%) were adults, while 23 (24.7%) belonged to the pediatric age group. Comparing these groups, mean age at onset was 32.5 years and 14.3 years, respectively. The average duration of follow-up was 11.08 months. Thirty percent of patients experienced relapsing episodes of headache with neurologic deficits and cerebrospinal fluid lymphocytosis symptoms. The most common type of headache reported was unilateral severe throbbing episodic headache. Other associated symptoms included sensory deficit (60%) and motor deficits (54.8%). The least common symptoms were nystagmus and agraphia, which were reported in one patient each. Antiviral agents were a common treatment option in the acute phase (n = 23 patients [23.6%]), while Flunarizine was the most commonly used agent in the chronic setting (n = 3 patients [3.2%]). While most of the patients had normal brain magnetic resonance imaging, 20 patients had magnetic resonance imaging abnormalities, including (but not limited to) non-specific white matter lesions (eight patients) and meningeal enhancement (six patients). The most common electroencephalographic findings included diffuse and focal slowing. The mean cerebrospinal fluid opening-pressure was 240.5 mmH2O. Cerebrospinal fluid protein was elevated in 59 (63.4%) patients, with a mean value of 114 mg/dL. Two patients in our cohort were found to have cerebrospinal fluid oligoclonal bands. Headache with neurologic deficits and cerebrospinal fluid lymphocytosis tends to affect young individuals with a slight male predominance. Unilateral severe throbbing episodic headache with associated hemi-paresthesia and hemiparesis were the most common symptoms based on our review. Elevated cerebrospinal fluid opening-pressure can be seen in headache with neurologic deficits and cerebrospinal fluid lymphocytosis syndrome. Early recognition of the syndrome is paramount. Antivirals were found to be among the most widely used treatments in the acute setting. Magnetic resonance imaging of the brain is mostly normal. Diffuse and focal slowing were among the most common electroencephalographic findings. Cerebral flow abnormalities on perfusion scans are not uncommon in headache with neurologic deficits and cerebrospinal fluid lymphocytosis. Prospective studies with a larger sample size are needed to validate our findings and guide the clinical care of these patients.

The Global Campaign Against Headache and its future relation to IHS and WHO.

Preparations for the Global Campaign Against Headache done jointly with WHO started almost 25 years ago. It was officially incorporated 18 years ago. It is the story of a few dedicated individuals who, together with the World Health Organization, generated epidemiological data all over the world and made use of these data to gradually increase the position of headache disorders, until migraine became number two among all causes of years lost to disability. It is also the story of impressive development of scientific tools, their validation and use in low-income countries. Models of care for headache patients were developed that are adaptable and hence can be implemented in future throughout the world. The last phase of the campaign shall use the impressive data set generated to cause real improvement in the healthcare for people with headache throughout the world. The recent World Health Organization initiative: Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders invites international organizations to collaborate, and headache is mentioned. This calls for the International Headache Society and all its national members and all other organizations involved in headache to work together with Lifting the Burden, the organization in charge of the Global Campaign Against Headache.

Consensus recommendations on the role of nurses in the care of headache patients: protocol for a european e-delphi study

BackgroundNurses play an important role in the treatment of headache patients at the specialized headache centers in Europe, however, a unified definition of nursing tasks and conduction of tasks is lacking. The objective of this e-Delphi study is twofold. Initially, to obtain healthcare professional headache experts’ opinions on which tasks are associated with nurses’ care in migraine treatment. Then, through an iterative multi-staged process, to combine the opinions into group consensus statements and develop evident European nursing recommendations for migraine treatment.MethodsIn Delphi studies there are no unambiguous methodological guidelines and this protocol is being published to ensure transparency and quality in the study process. We invite nurses working in specialized headache centers and neurologists co-working with nurses in Finland, Denmark, Norway, Sweden, United Kingdom, Netherlands, Germany, Ireland, Estonia and Switzerland to participate anonymously in the expert panel. This e-Delphi study consists of three rounds of online questionnaires. We use Open-ended questions to capture the essentials of nurse tasks as understood by the expert panel members. Data are analyzed using content analysis. Predefined statements are applied for the experts to rate the importance of nurses’ tasks synthesized from a systematic examination of the existing literature. Consensus is measured using descriptive statistics; median, Interquartile range (IQR) and percentage agreement. Measurement of agreement between participants will be analyzed using inferential statistics; Kendall’s coefficient and stability between rounds; Wilcoxon rank-sum test. Statements, which receive consensus in the third round, are included in the final compilation of European recommendations for nurse care for migraine patients.DiscussionThe e-Delphi study will provide European recommendations on nurse care in migraine treatment, which could not be created on the basis of the existing literature. The recommendations can open for the conduction of further research including measurement of efficacy of clinical implementation of the recommended tasks.Trial registrationThe study is registered at The Region of Southern Denmark (21/52,885). According to The Regional Ethical Committee and Danish law, no additional approval is relevant (20212000-145). A written informed consent is obtained from all participants before inclusion in the study.

Vajinismusta başağrısı, anksiyete ve depresyon

Abstract&#x0D; Objective: Vaginismus is one of the most common problems among patients who apply to the sexual health outpatient clinic. It is known that sexual problems are more common in migraine and tension-type headache patients. Furthermore, the frequency of depression and anxiety is higher in both vaginismus and chronic headache patients. This study was conducted in 2021 and examined the headache characteristics, depression and anxiety in vaginismus patients.&#x0D; Material and methods: In this prospective study, 87 patients diagnosed with vaginismus in the sexual health outpatient clinic were interviewed. Fifty patients who agreed to participate in the study were questioned regarding headache, and Beck depression and Beck anxiety scales were applied.&#x0D; Results: Headache was present in 46% (n:23) of 50 vaginismus patients. Anxiety scores of patients with headaches were higher than those without headaches (p=0.032). The most common type of headache was migraine without aura (60.9%), followed by tension-type headache (30.4%). Beck depression scores of the low-income group were higher than the high-income group (p=0.006). There was no significant correlation between monthly headache frequency, total headache duration, Beck depression score, and Beck anxiety score.&#x0D; Conclusions: Headache is a common neurological symptom in vaginismus patients, and the frequency of migraine is higher than tension-type headaches. Anxiety values are higher in vaginismus patients experiencing a headache. Therefore, headache and anxiety should be considered in the follow-up and treatment of vaginismus patients.

The effectiveness of botulinum toxin for chronic tension-type headache prophylaxis: A systematic review and meta-analysis.

A systematic and meta-analysis was conducted to examine the evidence of the effects of botulinum toxin A on chronic tension-type headache. Cochrane, Embase, Ovid, ProQuest, PubMed, Scopus, Web-of-Science databases, and ClinicallTrials.gov registry were systematically searched for studies examining the effects of botulinum toxin A on tension-type headaches. The records were screened by two independent reviewers using pre-determined eligibility criteria. DerSimonian Liard random-effects meta-analyses were performed using the 'meta' package (5.2-0) in R (4.2.0). Risk of bias and quality of evidence were assessed using the Cochrane Collaboration's Tool RoB 2 and Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. Clinical significance was determined using pre-defined minimal clinically important differences. Eleven controlled trials were included (390 botulinum toxin A, 297 controls). Botulinum toxin A was associated with significant improvements in standardized headache intensity (-0.502 standard deviations [-0.945, -0.058]), headache frequency (-2.830 days/month [-4.082, -1.578]), daily headache duration (-0.965 [-1.860, -0.069]) and the frequency of acute pain medication use (-2.200 days/month [-3.485, -0.915]) vs controls. Botulinum toxin A-associated improvements exceeded minimal clinically important differences for headache intensity, frequency, and acute pain medication use. A 79% (28%, 150%) greater response rate was observed for botulinum toxin A vs controls in improving chronic tension-type headache. Treatment of eight chronic tension-type headache patients was sufficient to elicit a therapeutic response in one patient. Corroborating the current mechanistic evidence, our meta-analysis supports the utility of botulinum toxin A for managing chronic tension-type headaches. However, due to limitations in the quality of evidence, adequately-powered high-quality controlled trials examining the effects of Botulinum toxin A on chronic tension-type headache are warranted.

DNA-methylation and immunological response in medication overuse headache.

To investigate whether medication-overuse headache patients have differential DNA-methylation pattern. We collected blood samples from 120 medication-overuse headache-patients, 57 controls (29 episodic migraine patients and 28 healthy controls) in a hypothesis-generating cross-sectional case-control pilot study; 100 of the medication-overuse headache-patients were followed for six months and samples were collected at two and six months for the longitudinal methylation analyses. Blood cell proportions of leucocytes (neutrophils, NK-cells, monocytes, CD8+ and CD4+ T-cells, and B-cells) and the neutrophile-lymphocyte ratio were estimated using methylation data as a measure for immunological analysis and a cell type-specific epigenome wide association study was conducted between medication-overuse headache-patients and controls, and longitudinally for reduction in headache days/month among medication-overuse headache-patients. We found a higher neutrophile-lymphocyte ratio in medication-overuse headache-patients compared to controls, indicating a higher immunological response in medication-overuse headache-patients (false discovery rate (adjusted p-value)<0.001). Reduction in headache days/month (9.8; 95% CI 8.1-11.5) was associated with lower neutrophile-lymphocyte ratio (false discovery rate adjusted p-value = 0.041).Three genes (CORIN, CCKBR and CLDN9) were hypermethylated in specific cell types in medication-overuse headache-patients compared to controls. No methylation differences were associated with reduction in headache days in medication-overuse headache-patients after six months. This pilot study was consistent with higher immunological response in medication-overuse headache-patients which decreased with a reduction in headache days in longitudinal analysis. medication-overuse headache-patients exhibited differential methylation in innate immune cells but did not exhibit longitudinal differences with alterations in headache days. Our study creates hypotheses for further biomarker searches.ClinicalTrials.gov Identifier: NCT02993289.
