Migraine Is the Most Prevalent Primary Headache in Individuals with Temporomandibular Disorders

Journal:Journal of Orofacial Pain (Summer 2010)

Authors:Franco A, Goncalves D, Castanharo S, et al.

Purpose:The study is designed to “assess the prevalence of primary headaches (HA) in adults with temporomandibular disorders (TMD) who were assessed in a specialty orofacial pain clinic, as well as in controls without TMD.”

Results:The study included “158 individuals with TMD seen at a university-based specialty clinic, as well as 68 controls.” The results demonstrated that “among individuals with TMD, migraine was the most prevalent HA (55.3%), followed by tension-type headache (30.2%),” and 14.5% had no headache. The researchers concluded that “TMD was associated with increased primary HA prevalence rates” and migraine was the most common primary HA diagnosis” for those with TMD.

Association between Body Mass Index and Migraine

Journal:European Neurology (July 22, 2010)

Authors:Téllez-Zenteno J, Pahwa D, Hernandez-Ronquillo L, et al.

Purpose:To “explore the prevalence of overweight and obesity in patients with migraine.”

Results:The researchers studied “1,371 patients with migraine and 612 controls.” Age and gender were matched for both groups. The results demonstrated that “overweight and obesity in migraine patients versus controls” was “statistically significant;” however, no “association was found between the disability and severity of migraine and BMI.”

Plasma and Saliva Levels of Nerve Growth Factor and Neuropeptides in Chronic Migraine Patients

Journal: Oral Diseases (July 23, 2010)

Authors:Jang M, Park J, Kho H, et al.

Purpose:The study was designed to “investigate the level and interrelationship of nerve growth factor (NGF) and sensory neuropeptides [substance P (SP), calcitonin gene-related peptide (CGRP)]” in the “plasma and saliva of chronic migraine patients.” Researchers also sought to “analyze the association between pain intensity and their concentration.”

Results:The “plasma and resting whole saliva were collected from 33 chronic migraine patients and 36 control subjects.” The results demonstrated that “chronic migraine patients showed higher NGF and neuropeptide levels in both plasma and saliva.” Also of note, “plasma NGF, and plasma and saliva levels of SP and CGRP were highly associated with pain intensity.” The researchers concluded that the “increased production of NGF and sensory neuropeptides may play an important role in the maintenance of pain in chronic migraine and analysis.”

//Clinical Trials

Pilot Study to Compare Frovatriptan vs. Topiramate for Prevention of Migraine

Study Type:Interventional

Age/Gender Requirements: 18 years (male/female)

Sponsor:Roger Cady, MD

Formulation and Evaluation of Rizatriptan Benzoate Mouth Disintegrating Tablets

Journal:Indian Journal of Pharmaceutical Sciences (January 2010)

Authors:Keny R, Desouza C, Lourenco C

Purpose:The investigation was designed to develop and evaluate mouth disintegrating tablets of rizatriptan benzoate.

Results:The team developed the disintegrating tablets using “superdisintegrants crospovidone, carboxymethylcellulose calcium, Indion 414 and Indion 234” through the “direct compression method.” The tablets were evaluated for “thickness, uniformity of weight, content uniformity, hardness, friability, wetting time, in vitro and in vivo disintegration time, mouth feel, in vitro drug release and assay by high performance liquid chromatography.” The researchers found that the “formulation containing combination of crospovidone and Indion 234” produced the best results. Also, “apart from fulfilling all official and other specifications, the tablets exhibited higher rate of release.”

Abnormal Brain Activity in Migraineurs

"There has been increasing evidence that the processing and perception of sensory stimuli is abnormal even outside of attacks," said Dr. Till Sprenger, regarding the results of study he and a team of researchers from CSF Headache Group and Technische Universität München. “Now our findings underline that abnormal brain activity in migraineurs is not restricted to attacks—that there is an extensive alteration of functional connectivity in multiple networks reflecting the migraineurs phenotype, emphasizing that migraine is a disorder of the brain."

Sedentary Activity Linked to Back Pain and Headache in Teenagers

Although the amount of time teenagers spend in front of the TV, as well as on the computer or playing video games, has long been associated with physical complaints, an international team of researchers has now definitively linked TV viewing, computer use, and computer gaming (screen time) to back pain and recurrent headaches.
