Critical analysis of the international classification of headache disorders diagnostic criteria (ICHD I-1988) and (ICHD II-2004), for migraine in children and adolescents

The present study analyzed the (ICHD I-1988) and ( ICHD II-2004) diagnostic criteria in children and adolescents. Our population consisted of 496 patients of the Headache Outpatient Ward for Children and Adolescents retrospectively studied from 1992 to 2002. Individuals were classified according to three diagnostic groups: Intuitive Clinical Diagnosis ( Gold Standard), ICHD I-1988 and ICHD II-2004. They were statistically compared using the variables: Sensitivity ( S), Specificity (Sp), Positive Predictive Value (PPV), Negative Predictive Value (NPV). When ICHD I-1988 was used, the sensitivity of migraine without and with aura was 21% and 27%, respectively, whereas in ICHD II-2004 it changed to 53% and 71% without affecting specificity. As a conclusion, the current classification criteria ( ICHD II-2004) showed greater sensitivity and high specificity for migraine than ICHD I-1988, although it improved migraine diagnosis in children and adolescents, the sensitivity remains poor.

How to Investigate and Treat: Migraine in Patients with Temporomandibular Disorders

Migraine and temporomandibular disorders (TMD) are highly prevalent conditions that frequently coexist in the same patient. The relationship between migraine and TMD is complex. Migraineurs often have pain in the TMD area; TMD sufferers, in turn, often experience headaches in addition to the pain in the jaw. Finally, migraine and TMD are comorbid, and the final phenotype of patients with the comorbidity may represent the aggregated contribution of both. Herein we briefly discuss the clinical commonalities of migraine and TMD, and the differential diagnosis of these conditions with other causes of facial pain. We close by presenting our experience in the treatment of patients with the comorbidity.

Lateral pterygoid muscle volume and migraine in patients with temporomandibular disorders

Lateral pterygoid muscle (LPM) plays an important role in jaw movement and has been implicated in Temporomandibular disorders (TMDs). Migraine has been described as a common symptom in patients with TMDs and may be related to muscle hyperactivity. This study aimed to compare LPM volume in individuals with and without migraine, using segmentation of the LPM in magnetic resonance (MR) imaging of the TMJ. Twenty patients with migraine and 20 volunteers without migraine underwent a clinical examination of the TMJ, according to the Research Diagnostic Criteria for TMDs. MR imaging was performed and the LPM was segmented using the ITK-SNAP 1.4.1 software, which calculates the volume of each segmented structure in voxels per cubic millimeter. The chi-squared test and the Fisher's exact test were used to relate the TMD variables obtained from the MR images and clinical examinations to the presence of migraine. Logistic binary regression was used to determine the importance of each factor for predicting the presence of a migraine headache. Patients with TMDs and migraine tended to have hypertrophy of the LPM (58.7%). In addition, abnormal mandibular movements (61.2%) and disc displacement (70.0%) were found to be the most common signs in patients with TMDs and migraine. In patients with TMDs and simultaneous migraine, the LPM tends to be hypertrophic. LPM segmentation on MR imaging may be an alternative method to study this muscle in such patients because the hypertrophic LPM is not always palpable.

Myofascial Pain Syndrome as a Contributing Factor in Patients with Chronic Headaches

Objectives: The purpose of this study was to evaluate the prevalence of active and latent trigger points [TrPs], as well as analyze the prevalence of different types of headaches in chronic headache patients. The active and latent TrPs in muscles of orofacial and cervical regions were also evaluated. Methods: There were 290 subjects who participated in this study. Trigger points were identified according to Simons et al.'s diagnostic criteria. Trigger points were considered active if subjects recognized the evoked referred pain as their familiar headache. If the evoked referred pain was not recognized as the familiar headache, the TrPs were considered latent. Differential diagnosis for headache was performed on the basis of International Headache Society criteria. Results: Trigger points could be diagnosed in 77 percent of patients and, in 89 percent of these, active TrPs were found. Muscle tenderness could be observed in 22 percent of patients, and only 1 percent patients were muscle-pain-free. The headache diagnosis showed that 26 percent had tension-type headache, 13 percent had migraine, and 61 percent had combined episodes of tension-type headache and migraine. The highest number of TrPs were found in temporalis [N = 159], masseter [N = 126], and occiptofrontalis [N = 113] muscles. Active TrPs were more frequent in temporalis and occiptofrontalis muscles. Conclusions: Subjects with chronic headaches had a higher prevalence of TrPs, and headache complaints could be reproduced during stimulation of active TrPs that were localized more frequently in temporalis and occiptofrontalis muscles. The presence of TrPs may be a contributing factor in the initiation and/or perpetuation of chronic headaches.
