Radiological anatomy assessment of the fissura pterygomaxillaris for a surgical approach to ganglion pterygopalatinum
2017
The ganglion pterygopalatinum has become a therapeutic target to treat various pain syndromes in recent years. It is located in the fossa pterygopalatina, and the fissura pterygomaxillaris is the main access to surgically approach this structure. Recently, the neuromodulation of the ganglion pterygopalatinum by microstimulator implantation has become the first therapeutic line in refractory cluster headache treatment. This invasive technique is performed transorally through the fissura pterygomaxillaris, and is limited by the size of the implantation device, which requires an opening of at least 2 mm. Therefore, extensive knowledge about the anatomy of the fissura pterygomaxillaris prior to…
Types of Triggers in Migraine - Factor Structure of the Headache Triggers Sensitivity and Avoidance Questionnaire and Development of a New Short Form…
2020
OBJECTIVE: To examine the factor structure of the Headache Triggers Sensitivity and Avoidance Questionnaire (HTSAQ) and its German version (HTSAQ-G), in order to identify potential different types of triggers. Furthermore, a short form of the questionnaire was developed. BACKGROUND: The HTSAQ includes 24 of the most commonly reported headache triggers (eg, stress, odors, lack of sleep). Both the HTSAQ and HTSAQ-G appeared to be reliable and valid measures of sensitivity to and avoidance of headache triggers. METHODS: In a cross-country collaboration, data from 2 cross-sectional studies including N = 391 individuals diagnosed with migraine from Australia (n = 222) and Germany (n = 169) were …
Determination of psychosocial factors in cluster headache - construction and psychometric properties of the Cluster Headache Scales (CHS).
2020
Background Cluster headache (CH) is clinically associated with considerable psychosocial burden. However, instruments to assess and characterize psychosocial factors in cluster headache more specifically are lacking. This study aimed to develop a self-report questionnaire, which assesses the broadest possible spectrum of psychosocial factors in cluster headache, the Cluster Headache Scales (CHS). Method Items of the Cluster Headache Scales were constructed based on a literature review and semi-structured interviews with several experts (including persons with cluster headache). A cross-sectional online survey was conducted to determine the psychometric properties and the factor structure of…
Age of onset of episodic and chronic cluster headache – a review of a large case series from a single headache centre
2016
Background In the largest case series of cluster headache (CH) published in the literature, age of onset varies between 29.6 and 31.6 years. Differences in onset age based on gender and subtype diagnosis are reported, while there are only few data on patients with childhood and elderly onset. We therefore deemed it useful to review our own large case series of CH patients. Methods The age of onset of cluster headache was investigated in a consecutive case series of 808 patients (585 men and 223 women), including 686 (503 men and 183 women) with episodic cluster headache (ECH), 103 (66 men and 37 women) with chronic cluster headache (CCH), and 19 with an indeterminate form of CH (16 men and …
Clinical course of patients with episodic cluster headache treated with corticosteroids inproximity to the sphenopalatine ganglion: A preliminary stu…
2011
Objective: A study is made of the clinical course of patients with episodic cluster headache following the injection of corticosteroids in the proximity of the sphenopalatine ganglion of the affected side. Study Design: A retrospective observation study was made corresponding to the period between 2006 and 2010. Patients with episodic cluster headache received corticosteroid infiltrations in the vicinity of the sphenopalatine ganglion. Data were collected to assess the clinical course, quantifying pain intensity and quality of life. A total of 23 patients (11 women and 12 men) with a mean age of 50.4 years (range 25-65) were included. Forty percent of the patients had undergone dental extra…
Switching on the deep brain stimulation: effects on cardiovascular regulation and respiration.
2011
Abstract Background Objective of this study was to evaluate the acute cardiovascular and respiratory effects of switching on the deep brain stimulation in the follow up of nine Parkinson's disease patients with subthalamic nucleus stimulation and six cluster headache patients with posterior hypothalamic area stimulation. Methods Systolic and diastolic blood pressure, heart rate, and respiratory rate were monitored continuously during supine rest in both groups. Each patient was assessed in two conditions: resting supine with stimulator off and with stimulator on. Results In supine resting condition switching on the DBS induced no significant changes ( p > 0.05) in systolic and diastolic bl…
Study of hypothalamic metabolism in cluster headache by proton MR spectroscopy
2006
The authors used 1H-MRS to investigate hypothalamic metabolism in 26 patients with cluster headache (CH) and 12 healthy subjects. Hypothalamic N-acetylaspartate/creatine was reduced in patients with CH vs controls (p < 0.01). Dividing the patients into episodic CH outside- and in-cluster periods and chronic CH, the hypothalamic N-acetylaspartate/creatine in all three subgroups of patients was reduced. The reduction of the neuronal marker N-acetylaspartate is consistent with hypothalamic neuronal dysfunction in patients with CH.
Lower-half facial migraine: a report of 11 cases.
2004
Purpose Vascular pain of the face constitutes a variant of pain of the head, and includes migraine, cluster headache, paroxysmal hemicrania, and a facial variant of the so-called lower-half migraine. Lower-half facial migraine is a condition difficult to classify; according to the international classifications it could not be found as an individual entity. The objective of the present study is to determine the difficulties we encountered in diagnosis, the ineffective treatments provided, and the pharmacologic treatment effect. Patients and methods A study is made of 11 cases of lower-half facial migraine, corresponding to 10 women and 1 man (mean age, 35 years), commenting on the clinical c…
Transcranial magnetic stimulation reveals cortical hyperexcitability in episodic cluster headache
2014
Abstract Evidence shows involvement of the cerebral cortex in the pathophysiology of cluster headache (CH). Here we investigated cortical excitability in episodic CH patients by using transcranial magnetic stimulation. In 25 patients with episodic CH and 13 healthy subjects we evaluated the motor cortical response to single-pulse (ie, motor threshold, input-output curves, cortical silent period) and paired-pulse (ie, intracortical facilitation, short intracortical inhibition) transcranial magnetic stimulation in both hemispheres. Thirteen patients were evaluated outside bout and the remaining 12 patients inside bout. Our results showed increased slope of the input-output curves after stimul…
Elusive amines and cluster headache: mutational analysis of trace amine receptor cluster on chromosome 6q23.
2004
Cluster headache (CH) is characterised by unilateral pain and ipsilateral autonomic features. To date, no molecular genetic evidence has been shown for CH. Small pedigrees and low penetrance render the identification of the CH-gene quite difficult. Nonetheless the association of CH and migraine to a new class of amine, namely trace or elusive amines such as tyramine, octopamine and synephrine, has recently been demonstrated. In particular, in comparison to healthy control subjects, all these neurotransmitters have been found to be greatly elevated in CH sufferers in plasma and platelets both in active and remission periods. A cluster of gene-encoding G-protein-coupled receptors that bind an…
