ABSTRACT
Postcraniotomy and posttraumatic headaches can result in scars generating local pain or referred pain following a neuropathic pattern. One hypothesis is that the pain can be caused and maintained by scar neuromas, developed after the nerve injury during the surgical process or trauma. This study reports two patients with chronic unilateral headaches: the first one with a posttraumatic scar in the parietal region and the other with a postsurgical scar in the mastoid region. In both patients, the headache was ipsilateral to the scar, suggesting primary headaches (trigeminal autonomic cephalalgia (TAC), as hemicrania continua and chronic cluster headache). Pharmacological treatment for these conditions failed. Instead, there was complete remission of the headache with anesthetic blockade of scar neuromas (demonstrated by clinical examination in both patients). An active search for traumatic or nontraumatic scars is recommended in all patients with refractory unilateral headaches, and anesthetic blocks for scar neuromas can be effective in treating this pain.
ABSTRACT
OBJECTIVE: The purpose of this study was to investigate the correlation between head and neck posture and superficial neck flexor and extensor activity during performance of the craniocervical flexion test (CCFT) in women with migraine and healthy controls. METHODS: Fifty-two women with episodic migraine, 16 with chronic migraine, and 23 healthy controls participated. Head and neck posture were determined by assessing the craniovertebral (CV) angle and cervical lordosis angle. Surface electromyography signals were recorded bilaterally from sternocleidomastoid, anterior scalene, splenius capitis, and upper trapezius muscles as participants performed the CCFT. Differences in electromyogram activity and posture among groups were compared with analyses of variance. Correlations between posture and electromyogram activity were analyzed with the Pearson correlation coefficient. RESULTS: Both migraine groups had a significant increase in splenius capitis muscle activity, when acting as an antagonist, at the last stage of CCFT (F = 4.687; P = .012) compared with controls. No differences among groups were observed for head and neck posture. No significant correlation was found in the episodic migraine group. Moderate correlations between the CV angle and upper trapezius activity at the majority stages of the CCFT (-0.61 < r < -0.65, all P < .05) were observed within the chronic migraine group: the more extended the head posture, the higher the activity of the upper trapezius muscle. The CV angle also was correlated with upper trapezius muscle activity at the first stage of the CCFT and with splenius capitis muscle activity at the last stages (-0.42 < r < -0.52; P < .05). CONCLUSION: An extended (forward) head posture was moderately correlated with an increased in electrical activity of superficial neck extensor muscles, particularly the upper trapezius, when acting as an antagonist, during the performance of the CCFT in women with chronic but not episodic migraine.

BACKGROUND: The role of musculoskeletal disorders of the cervical spine in migraine is under debate. AIM: To investigate differences in musculoskeletal impairments of the neck including active global and upper cervical spine mobility, the presence of symptomatic upper cervical spine joints, cervicocephalic kinesthesia and head/neck posture between women with episodic migraine, chronic migraine, and controls. DESIGN: A cross-sectional study. SETTING: Tertiary university-based hospital. POPULATION: Fifty-five women with episodic migraine, 16 with chronic migraine, and 22 matched healthy women. METHODS: Active cervical range of motion, upper cervical spine mobility (i.e., flexion-rotation test), referred pain from upper cervical joints, cervicocephalic kinesthesia (joint position sense error test, JPSE), and head/neck posture (i.e. the cranio-vertebral and cervical lordosis angles) were assessed by an assessor blinded to the subject's condition. RESULTS: Women with migraine showed reduced cervical rotation than healthy women (P=0.012). No differences between episodic and chronic migraine were found in cervical mobility. Significant differences for flexion-rotation test were also reported, suggesting that upper cervical spine mobility was restricted in both migraine groups (P<0.001). Referred pain elicited on manual examination of the upper cervical spine mimicking pain symptoms was present in 50% of migraineurs. No differences were observed on the frequency of symptomatic upper cervical joints between episodic and chronic migraine. No differences on JPSE or posture were found among groups (P>0.121). CONCLUSIONS: Women with migraine exhibit musculoskeletal impairments of the upper cervical spine expressed as restricted cervical rotation, decreased upper cervical rotation, and the presence of symptomatic upper cervical joints. No differences were found between episodic or chronic migraine. CLINICAL REHABILITATION IMPACT: Identification treatment of the musculoskeletal impairments of the cervical spine may help to clinician for better management of patients with migraine.

OBJECTIVE: Previous studies have demonstrated the presence of active trigger points (TrPs) in women with migraine reproducing their headache attacks. No study has investigated whether these TrPs can alter cervical muscle function in migraine. Our objective was to analyze differences in the activation of superficial neck flexor and extensor muscles in women with migraine considering the presence of active TrPs in the splenius capitis (SC), the upper trapezius (UT), and the sternocleidomastoid (SCM) muscles. METHODS: Surface electromyography (EMG) was recorded from the superficial flexors (SCM and anterior scalene) and the extensor (SC, UT) muscles bilaterally as participants performed a staged task of cranio-cervical flexion (CCF; 5 contractions representing a progressive increase in CCF range of motion) in 70 women with migraine. They were stratified according to the presence or the absence of active TrPs in the SCM, the SC, or the UT musculature. A comparison of EMG normalized root mean square (RMS) values was conducted with a 2×5 analysis of covariance with the task level as the within-subject variable, group stratified by active TrPs as the between-subjects variable and the presence of neck pain as a covariable. RESULTS: All patients exhibited active TrPs in their cervical muscles, which reproduced their migraine. Women with migraine exhibiting active TrPs in the SCM (P<0.01), the UT (P<0.05), or the SC (P<0.05) muscles had lower normalized RMS values of their superficial neck flexors than those without active TrPs in the same muscles. In addition, individuals exhibiting active TrPs in the SC and the UT (both, P<0.05) muscles had higher normalized RMS values in the SC muscle than those without active TrPs in the same muscles. CONCLUSIONS: The presence of active TrPs in the cervical musculature determines an altered activation of superficial neck and extensor muscles during low-load, isometric CCF contractions in women with migraine.

OBJECTIVE: The aim of this study was to investigate the differences in the presence of head and neck-shoulder trigger points (TrPs) between women with episodic or chronic migraine and their association with migraine-related disability. MATERIALS AND METHODS: One hundred forty-three women, aged 18 to 60 years, with migraine were recruited to participate in this study. Migraine-related disability was evaluated with the Migraine Disability Assessment Questionnaire. TrPs were explored bilaterally within the masseter, temporalis, suboccipital, sternocleidomastoid, upper trapezius, and splenius capitis muscles. RESULTS: Ninety-eight women exhibited episodic migraine, whereas 45 had chronic migraine. Women with chronic migraine reported a higher related disability than those with episodic migraine (P=0.045). Women with episodic migraine had a similar number of TrPs (total number: 4.3±3.3; active TrPs: 3.0±2.9; and latent TrPs: 1.3±2.1) to those with chronic migraine (total number: 4.8±3.2; active TrPs: 3.4±2.9; and latent TrPs: 1.4±1.9). No linear association was observed between the number of TrPs and migraine-related disability in women with episodic or chronic migraine. CONCLUSIONS: Women with episodic and chronic migraine had a similar number of TrPs. TrPs may be considered a trigger factor that can facilitate the onset of migraine or also can potentially be a promoting factor for pain once the migraine attack has started and hence may contribute to related disability. Nevertheless, we observed that the number of TrPs in the head and neck-shoulder muscles in an interictal state was not associated with the degree of migraine-related disability, suggesting a multifactorial nature of self-perceived disability in this population.

OBJECTIVES: The aim of this study was to assess differences in the levels of hyperalgesia and cutaneous allodynia (CA) among women with migraine, temporomandibular disorders (TMD), or both. MATERIALS AND METHODS: Eighty women participated in the study. Mean ages for the control group, TMD group, migraine group, and migraine+TMD group were 26.15 (95% confidence interval [CI], 28.73 to 23.57), 31.65 (95% CI, 37.82 to 25.48), 35.05 (95% CI, 40.37 to 29.73), and 34.20 (95% CI, 37.99 to 30.41) years, respectively. The 12-item Allodynia Symptom Checklist was administered to assess CA. All participants underwent the Quantitative Sensory Test to determine the cold-pain and heat-pain thresholds. Mechanical pain thresholds were assessed using Semmes-Weinstein monofilaments. One-way analysis of variance and χ tests were used for statistical analysis. Alpha was set at 0.05 level for statistical significance. RESULTS: For all sites evaluated, the mean cold-pain threshold values were significantly lower in the TMD, migraine, and TMD+migraine groups compared with the control group. However, the mean heat-pain threshold values in the extracephalic region were significantly smaller only for the TMD+migraine group compared with the control group (41.94°C; 95% CI, 40.54 to 43.34 vs. 44.79°C; 95% CI, 43.45 to 46.12; P=0.03). Mechanical hyperalgesia in orofacial and neck sites was significantly lower in the TMD and TMD+migraine groups compared with the control group. Mean total 12-item Allodynia Symptom Checklist score in the TMD+migraine group was significantly higher than in the migraine group (9.53; 95% CI, 7.45 to 11.60 vs. 6.95; 95% CI, 5.35 to 8.55; P=0.02). CONCLUSIONS: More pronounced levels of hyperalgesia and CA were found in patients with both TMD and migraine. Thus, it is suggested that the concomitant presence of TMD and migraine may be related to intensification of central sensitization.

It has been well established that primary headaches (especially migraine, chronic migraine, and tension-type headache) and temporomandibular dysfunction (TMD) are comorbid diseases, with the presence of one of them in a patient increasing the prevalence of the others. The relationship between the 2 diseases may involve the sharing of common physiopathological aspects. Studies about the treatment of this disease association have shown that a simultaneous therapeutic approach to the 2 diseases is more effective than the separate treatment of each. As a consequence, specialists in orofacial pain are now required to know the criteria for the diagnosis of headaches, and headache physicians are required to know the semiologic aspects of orofacial pain. Nevertheless, a headache may be attributed to TMD, instead be an association of 2 problems - TMD and primary headaches - in these cases a secondary headache, described in item 11.7 of the International Classification of Headache Disorders, is still a controversial topic. Attempts to determine the existence of this secondary headache with a specific or suggestive phenotype have been frustrated. The conclusion that can be reached based on the few studies published thus far is that this headache has a preferential unilateral or bilateral temporal location and migraine-like or tension-type headache-like clinical characteristics. In the present review, we will consider the main aspects of the TMD-headache relationship, that is, comorbidity of primary headaches and TMD and clinical aspects of the headaches attributed to TMD from the viewpoint of the International Headache Society and of a group of specialists in orofacial pain. This paper aims to explore our understanding of the association between TMD and headaches in general and migraine in particular.

BACKGROUND: Several studies have presented evidence that blocking peripheral nerves is effective for the treatment of some headaches and cranial neuralgias, resulting in reduction of the frequency, intensity, and duration of pain. OBJECTIVES: In this article we describe the role of nerve block in the treatment of headaches and cranial neuralgias, and the experience of a tertiary headache center regarding this issue. We also report the anatomical landmarks, techniques, materials used, contraindications, and side effects of peripheral nerve block, as well as the mechanisms of action of lidocaine and dexamethasone. CONCLUSIONS: The nerve block can be used in primary (migraine, cluster headache, and nummular headache) and secondary headaches (cervicogenic headache and headache attributed to craniotomy), as well in cranial neuralgias (trigeminal neuropathies, glossopharyngeal and occipital neuralgias). In some of them this procedure is necessary for both diagnosis and treatment, while in others it is an adjuvant treatment. The block of the greater occipital nerve with an anesthetic and corticosteroid compound has proved to be effective in the treatment of cluster headache. Regarding the treatment of other headaches and cranial neuralgias, controlled studies are still necessary to clarify the real role of peripheral nerve block.

BACKGROUND: Migraine and temporomandibular disorders (TMDs) are reported to be associated. However, there are no reports on the association among migraines, TMDs and changes in body posture. OBJECTIVES: To assess changes in body posture in women suffering migraines with or without TMD compared with a control group. METHOD: Sixty-six women with a mean age of 18 to 45 years participated in this study. The groups were composed of 22 volunteers with migraine and TMD (MTMD), 22 volunteers with migraines without TMD (MG) and 22 women in the control group (CG). Static posture was assessed by photogrammetry, and 19 angles were measured. RESULTS: Postural asymmetry was observed in the face for 4 angles measured on the frontal plane in the MG group and for 4 angles of the trunk in the MG and MTMD groups with respect to CG. However, for comparisons between MTMD and CG, clinical relevance was identified for two angles of the sagittal plane (Cervical and Lumbar Lordosis, Effect Size - ES - moderate: 0.53 and 0.60). For comparisons between the MG and CG, the clinical relevance/potential was verified for three angles with moderate ES (ES>0.42). The clinical relevance when comparing MTMD and CG was identified for four angles of facial symmetry head inclination (ES>0.54) and for two angles between MG and CG (ES>0.48). CONCLUSION: The results demonstrated the presence of postural changes compared with a control group in women with migraines with or without TMD, and there were similar clinically relevant postural changes among the patients with migraines with and without TMD.

Contextualização: Há relatos na literatura sobre associações entre migrânea e disfunção temporomandibular (DTM). Entretanto, não há relatos sobre a associação entre migrânea, DTM e alterações da postura corporal. Objetivos: Avaliar a presença de alterações da postura corporal em mulheres com migrânea com e sem DTM em relação a um grupo controle. Método: Foram avaliados três grupos de 22 integrantes cada, na faixa etária de 18 a 50 anos, sexo feminino, compostos de voluntárias com migrânea e DTM (GMDTM), migranosas sem DTM (GM) e grupo controle (GC). As voluntárias foram submetidas à avaliação da postura estática por meio da fotogrametria, e foram mensurados 19 ângulos. Resultados: Foram observadas assimetrias posturais em quatro ângulos mensurados no plano frontal na face no GM e em quatro ângulos do tronco no GM e no GMDTM em relação ao GC. Entretanto, foi verificada relevância clínica para dois ângulos posturais no plano sagital (GM vs. GMDTM - lordose cervical e lombar, Effect size - ES moderados: 0,53 e 0,60) e, para comparação entre o GM e o GC, foi observada relevância clínica/potencial para três ângulos (ES>0,42). Foi verificada relevância clínica para quatro ângulos de simetria facial/inclinação da cabeça na comparação GMDTM e GM (ES>0,54) e para dois ângulos entre o GM e o GC (ES>0,48). Conclusão: Os resultados do presente trabalho demonstraram a presença de alterações de postura corporal em mulheres com migrânea com e sem DTM em relação ao grupo controle, e as alterações de postura foram similares entre os GM e GMDTM na análise de relevância clínica. .

AIMS: To investigate the effectiveness of single and concomitant treatment of migraine and temporomandibular disorders (TMD) in women with the comorbidity. METHODS: Eligible female patients met International Classification of Headache Disorders, second edition (ICHD-2) criteria for migraine with or without aura and the Research Diagnostic Criteria for myofascial TMD (Grade ll or lll). After a run-in period (30 days), women with both migraine and TMD were enrolled into a four-arm, double-blind, placebo-controlled, factorial study testing the separate and joint effects of a migraine treatment (propranolol 90 mg) and a TMD treatment (stabilization splint [SS]) in four groups of patients. The four treatment groups were propranolol and SS (n = 22); propranolol placebo and SS (n = 23); propranolol and non-occlusal splint (NOS) (n = 23); and propranolol placebo and NOS (n = 21). The primary endpoint for migraine was change in headache days from baseline to the third month, and the secondary endpoint was change in days with at least moderate headache in the same period. The TMD endpoints included pain threshold and mandibular vertical range of motion. Data were analyzed using analysis of variance (ANOVA, Dunn's post-hoc test) or Kruskal-Wallis test. RESULTS: For the primary endpoint, in intention-to-treat (ITT) analyses (n = 94), propranolol and SS were associated with a nonsignificant reduction in the number of headache days, relative to all other groups. For per-protocol (PP) Completer analyses (n = 89), differences in the number of headache days reached significance (P < .05). The propranolol and SS group was significantly superior to the other groups on all other headache endpoints and in disability, in both ITT and PP analyses. No significant differences among groups were seen for the TMD parameters. CONCLUSION: In women with TMD and migraine, migraine significantly improved only when both conditions were treated. The best treatment choice for TMD pain in women with migraine is yet to be defined.

OBJECTIVE: The pathophysiology of migraine and restless legs syndrome (RLS) seems to involve inherited mechanism and dysfunction of the dopaminergic system. Previous articles have shown that the frequency of RLS is higher in migraine patients than in controls. We conducted a study to evaluate comorbidities, medication used and depressive symptoms that can explain the relation between migraine and RLS. METHODS: A case-control study was performed in which patients with migraine (n=72) and a control group without migraine (n=72) were interviewed. Data including RLS diagnosis, depressive symptoms, comorbidities and drugs used were evaluated. RESULTS: There was a significant association between migraine and RLS (p=0.01), but comorbidities such as diabetes, hypertension, anemia and drugs used did not explain this association. Depression scores, as measured by the Beck Depression Inventory, were higher in migraine patients with RLS (p =0.04). CONCLUSION: No specific factors explaining the association between migraine and RLS were found. Symptoms of depression were more frequent in patients with migraine and RLS.
OBJETIVO: A fisiopatologia da enxaqueca e da síndrome das pernas inquietas (SPI) parece envolver mecanismos genéticos e disfunção do sistema dopaminérgico. Artigos anteriores mostraram que a frequência de SPI em pacientes com enxaqueca é maior do que nos controles. Desenvolvemos um estudo para avaliar comorbidades, medicamentos utilizados e sintomas depressivos em pacientes com migrânea e SPI. MÉTODOS: Foi desenvolvido um estudo de caso-controle. Foram entrevistados pacientes com enxaqueca (n=72) e sujeitos de um grupo controle (n=72). Foram avaliados dados incluindo diagnóstico de SPI, sintomas depressivos, comorbidades e medicamentos usados. RESULTADOS: Houve associação significativa entre enxaqueca e SPI (p=0,01). Comorbidades como diabetes, hipertensão, anemia ou drogas utilizadas não explicam esta associação. Escores de depressão, medidos pelo Inventário de Beck, foram mais altos em pacientes com enxaqueca e SPI (p=0,04). CONCLUSÃO: Não foram encontrados fatores específicos que explicam a associação entre enxaqueca e SPI. Sintomas de depressão foram mais frequentes em pacientes com enxaqueca e SPI.

OBJECTIVES: The aim of this study was to assess the prevalence of Temporomandibular Disorders (TMD), using the Research Diagnostic Criteria for TMD (RDC/TMD) in women with episodic and chronic migraine (M and CM), as well as in asymptomatic women. METHOD: Sample consisted of 61 women, being 38 with M and 23 with CM, identified from a headache outpatient center; we also investigated 30 women without headaches for at least 3 months (women without headache group - WHG). Assessment of TMD was conducted by a physical therapist who was blind to the headache status. RESULTS: The prevalence of TMD, assessed through the RDC, was 33.3% in the WHG, 86.8% in the M group and 91.3% of the CM group. Differences were significant when comparing M and CM groups with WHG (p<0.001), but not when comparing M and CM (p>0.05) as well as higher risk for TMD [odds ratio (OR)=3.15, 95% confidence interval (CI) 1.73-5.71 and OR=3.97, 95%CI 1.76-8.94]. CONCLUSION: Women with migraine are more likely to have muscular and articular TMD, suggesting that both disorders might be clinically associated, which demonstrate the importance of physical therapy assessment in the multidisciplinary team.
OBJETIVOS: Avaliar a presença de disfunção temporomandibular (DTM) usando o Critério Diagnóstico em pesquisa para disfunção temporomandibular (RDC/TMD) em mulheres com migrânea episódica e migrânea crônica (M e MC), bem como em mulheres sem nenhuma cefaleia. MÉTODO: A amostra foi composta por 61 mulheres, 38 com M e 23 com MC, selecionadas em um centro terciário de saúde; também foram avaliadas 30 mulheres sem nenhuma cefaleia nos últimos três meses (grupo de mulheres sem cefaleia - MSC). A avaliação da DTM foi realizada por um fisioterapeuta que não tinha conhecimento do diagnóstico das pacientes. RESULTADOS: Por meio do RDC/TMD, a frequência de DTM foi de 33.3% no grupo MSC, 86.8% no grupo M e 91.3% no grupo MC. A diferença foi significativa entre os grupos com migrânea e o grupo MSC (p<0.001), porém não houve diferença entre os grupos M e MC (p>0,05), bem como maior fator de risco de DTM [odds ratio (OR)=3,15, intervalo de confiança (IC) de 95% 1,73-5,71 e OR=3,97, IC95% 1,76-8,94]. CONCLUSÃO: Mulheres com migrânea têm maior frequência de DTM muscular e articular, sugerindo que essas condições estão clinicamente associadas, evidenciando a importância do fisioterapeuta na equipe de avaliação multidisciplinar.

Matrix metalloproteinases (MMP) are involved in the disruption of blood-brain barrier (BBB) during migraine attacks. In the present study, we hypothesized that two functional polymorphisms (C(-1306)T and C(-735)T) in MMP-2 gene and MMP-2 haplotypes are associated with migraine and modify MMP-2 and tissue inhibitor of MMP (TIMP)-2 levels in migraine. Genotypes for MMP-2 polymorphisms were determined by real time-PCR using Taqman allele discrimination assays. Haplotypes were inferred using the PHASE program. Plasma MMP-2 and TIMP-2 concentrations were measured by gelatin zymography and ELISA, respectively, in 148 healthy women without history of migraine and in 204 women with migraine (153 without aura; MWA, and 51 with aura; MA). Patients with MA had higher plasma MMP-2 concentrations and MMP-2/TIMP-2 ratios than patients with MWA and controls (P<0.05). While MMP-2 genotype and haplotype distributions for the polymorphisms were similar among the groups (P>0.05), we found that the CC genotype for C(-735)T polymorphism and the CC haplotype were associated with higher plasma MMP-2 concentrations in MA group (P<0.05). Our findings may help to understand the role of MMP-2 and its genetic variants in the pathophysiology of migraine and to identify a particular group of migraine patients with increased MMP-2 levels that would benefit from the use of MMP inhibitors.

Trigeminal neuralgia (TN) is a condition characterized by brief electric shock-like pains in the topography of the trigeminal nerve. The most common cause of this disorder is the compression of the trigeminal nerve root by tortuous or aberrant vessels. In this report, we describe a patient who presented due to paroxysmal and excruciating facial pain that was found to be secondary to pancreatic cancer.

The pathogenic mechanisms involved in migraine are complex and not completely clarified. Because there is evidence for the involvement of nitric oxide (NO) in migraine pathophysiology, candidate gene approaches focusing on genes affecting the endothelial function have been studied including the genes encoding endothelial NO synthase (eNOS), inducible NO synthase (iNOS), and vascular endothelial growth factor (VEGF). However, investigations on gene-gene interactions are warranted to better elucidate the genetic basis of migraine. This study aimed at characterizing interactions among nine clinically relevant polymorphisms in eNOS (T(-786)C/rs2070744, the 27 bp VNTR in intron 4, the Glu298Asp/rs1799983, and two additional tagSNPs rs3918226 and rs743506), iNOS (C(-1026)A/rs2779249 and G2087A/rs2297518), and VEGF (C(-2578)A/rs699947 and G(-634)C/rs2010963) in migraine patients and control group. Genotypes were determined by real-time polymerase chain reaction using the Taqman(®) allele discrimination assays or PCR and fragment separation by electrophoresis in 99 healthy women without migraine (control group) and in 150 women with migraine divided into two groups: 107 with migraine without aura and 43 with aura. The multifactor dimensionality reduction method was used to detect and characterize gene-gene interactions. We found a significant interaction between eNOS rs743506 and iNOS 2087G/A polymorphisms in migraine patients compared to control group (P < 0.05), suggesting that this combination affect the susceptibility to migraine. Further studies are needed to determine the molecular mechanisms explaining this interaction.
