We conducted an investigation of Borrelia miyamotoi infections in humans and ticks in northeastern China. Of 984 patients reporting recent tick bites, 14 (1.4%) were found to be infected with B. miyamotoi by PCR and genomic sequencing. The 14 patients had nonspecific febrile manifestations, including fever, headache, anorexia, asthenia, and arthralgia. Rash, eschar, and regional lymphadenopathy were each observed in 1 patient. Four (28.6%) patients were hospitalized because of severe disease. B. miyamotoi was detected in 3...

BACKGROUND: Cluster headache (CH) is a disabling primary headache disorder characterized by severe periorbital pain. A subset of patients does not respond to established pharmacological therapy. This study examines outcomes of a cohort of mainly chronic CH patients treated with sphenopalatine ganglion (SPG) stimulation. METHODS: Patients were followed in an open-label prospective study for 12 months. Ninety-seven CH patients (88 chronic, 9 episodic) underwent trans-oral insertion of a microstimulator targeting the SPG...

"Sinus headache" is a common chief complaint that often leads patients to an otolaryngologist's office. Because facial pain may or may not be sinogenic in origin, the otolaryngologist should be equipped to evaluate and treat or to appropriately refer these patients. Analysis of current data indicates that the majority of patients who present with sinus headaches actually have migraines. Furthermore, the downstream effect of the cytokine cascade initiated in migraine physiology can cause rhinologic symptoms, including rhinorrhea, congestion, and lacrimation, which may also confound diagnosis...

BACKGROUND: Deep brain stimulation (DBS) is an important form of neuromodulation that is being applied to patients with motor, mood, or cognitive circuit disorders. Despite the efficacy and widespread use of DBS, the precise mechanisms by which it works remain unknown. Over the last decade, magnetoencephalography (MEG) has become an important functional neuroimaging technique used to study DBS. OBJECTIVE: This review summarizes the literature related to the use of MEG to characterize the effects of DBS...

BACKGROUND: Cluster headache (CH), a rare primary headache disorder, is currently thought to be a genetic susceptibility which play a role in CH susceptibility. A large numbers of genetic association studies have confirmed that the HCRTR2 (Hypocretin Receptor 2) SNP rs2653349, and the ADH4 (Alcohol Dehydrogenase 4) SNP rs1126671 and rs1800759 polymorphisms are linked to CH. In addition, the CLOCK (Circadian Locomotor Output Cycles Kaput) gene is becoming a research hotspot for CH due to encoding a transcription factor that serves as a basic driving force for circadian rhythm in humans...

A panel of 9 experts, including neurologists, other headache specialists, and medical and pharmacy directors, from 4 health plans (1 integrated delivery network and 3 plans with commercial, Medicare, and Medicaid lines of business), convened to discuss cluster headache (CH). Topics covered included the current treatment landscape, treatment challenges, economic impact of disease, and gaps in care for patients with CH. One major challenge in the management of CH is that it is underrecognized and frequently misdiagnosed, leading to delays in and suboptimal treatment for patients who suffer from this painful and disabling condition...

The FDA has cleared gammaCore (non-invasive vagus nerve stimulator [nVNS]) for the treatment of episodic cluster headache (eCH). With the exception of subcutaneous sumatriptan, all other treatments are used off label and have many limitations. The FDA approval process for devices differs from that of drugs. We performed a review of the literature to evaluate new evidence on various aspects of gammaCore treatment and impact. The ACute Treatment of Cluster Headache Studies (ACT1 and ACT2), both double-blind sham-controlled randomized trials, did not meet the primary endpoints of the trials but each demonstrated significant superiority of gammaCore among patients with eCH...

Stimulation of the cervical vagus nerve with implanted vagus nerve stimulation (iVNS) has been used clinically for more than 20 years to treat patients with epilepsy. More recently, a non-invasive cervical vagus nerve stimulation (nVNS), gammaCore, was developed, which has been purported to also stimulate the vagus nerve without the cost and morbidity associated with an iVNS system. gammaCore has been used to acutely treat various types of primary headaches, including migraine and cluster headaches (CH), and for the prevention of episodic, chronic, and menstrual migraines and CH...

BACKGROUND: Sphenopalatine ganglion is the largest collection of neurons in the calvarium outside of the brain. Over the past century, it has been a target for interventional treatment of head and facial pain due to its ease of access. Block, radiofrequency ablation, and neurostimulation have all been applied to treat a myriad of painful syndromes. Despite the routine use of these interventions, the literature supporting their use has not been systematically summarized. This systematic review aims to collect and summarize the level of evidence supporting the use of sphenopalatine ganglion block, radiofrequency ablation and neurostimulation...

Headache is a common episodic or chronic neurologic disorder. Treatment options and diagnosis are restricted by an incomplete understanding of disease pathology and the lack of diagnostic markers. Wu-Zhu-Yu decoction (WZYD), a traditional Chinese medicine (TCM) formula containing four TCM herbs, is commonly used in the treatment of headache in China. To deeply understand more about headache and investigate the pain-relief mechanism of WZYD, a comprehensive metabolomics study combined with multivariate data processing strategy was carried out...

Multinodular and vacuolating neuronal tumors (MVNT) are low grade neuronal tumors classified in cerebral tumors based on 2016 WHO central nerve system classification. Previously, MVNTs were probably tumors incidentally determined by imaging methods, but they could not be diagnosed or they were misdiagnosed. Two cases are reported in the present study, for which radiological imaging was carried out for epilepsy in one and for headache in the other. The first case was a twenty seven years old female patient with headache complaint...

Background Clinical observations and results from recent studies support the use of non-invasive vagus nerve stimulation (nVNS) for treating cluster headache (CH) attacks. This study compared nVNS with a sham device for acute treatment in patients with episodic or chronic CH (eCH, cCH). Methods After completing a 1-week run-in period, subjects were randomly assigned (1:1) to receive nVNS or sham therapy during a 2-week double-blind period. The primary efficacy endpoint was the proportion of all treated attacks that achieved pain-free status within 15 minutes after treatment initiation, without rescue treatment...

BACKGROUND/OBJECTIVES: Puberty seems to be a turning point in cluster headache (CH) onset. To verify its influence on CH phenotype, we focused on cases with onset ≤13 years. A review of the literature follows. METHOD: We considered CH cases with age-of-onset ≤13 years evaluated at our center between 1975 and 2015; these cases were matched by sex to two consecutive patients with age-of-onset as close as possible (±2 years) to the median age-of-onset of the overall CH population...

BACKGROUND: Indoor residual spraying of insecticide (IRS) is a key intervention for reducing the burden of malaria infection. Effectiveness and success of this strategy are to a considerable extent dependent on knowledge and practice of the target community regarding the IRS. Iran has entered the malaria elimination phase, and IRS has been considered as the main strategy for malaria vector control. Therefore, this study was conducted to determine the household knowledge and practices about malaria and IRS in Bashagard County, one of the malaria-endemic areas in the southeast of Iran...
