The coexistence of paroxysmal hemicrania and temporomandibular disorder: Importance of multidisciplinary approach.

Paroxysmal hemicrania (PH) is a trigeminal autonomic cephalalgia, a rare primary headache characterized by unilateral periorbital and/or temporal attacks of severe intensity and short duration. In this situation, the determination of a correct diagnosis is crucial for the establishment of a proper management strategy. In the case of head and facial pain, this step is usually a big challenge since many conditions share the same features, as some primary headaches and temporomandibular disorders (TMD). The relationship between PH and TMD has not been determined. This paper describes a case of a female patient diagnosed with TMD and presenting concomitant headache attacks fulfilling the International Headache Society's criteria for PH. It is also emphasized the importance of dentist in this scenario, for many times responsible for the initial diagnosis of facial/head pain. Moreover, it is presented an integrated and simultaneously approach of both conditions, PH and TMD.

Cefaleas trigémino autonómicas: 3 casos de localización dentomaxilar / Trigeminal autonomic cephalalgias: 3 cases of dentomaxillar location

Las cefaleas trigemino autonómicas (CTAs: cefalea tipo cluster, hemicránea paroxística y el SUNCT) son un grupo de cefaleas primarias, caracterizadas por la presencia de dolor unilateral en la distribución somática del nervio trigémino, asociada a características autonómicas cráneofaciales ipsilaterales. A pesar de sus elementos comunes, de forma individual, difieren con respecto a su duración, frecuencia y la respuesta a indometacina. Se presentan tres casos de CTAs de localización primaria dentomaxilar, sus características comunes y particulares, y la necesidad del diagnóstico diferencial con cuadros dolorosos provenientes de estructuras estomatognáticas.

The Trigeminal Autonomic Cephalalgias (TACs: Cluster headache, paroxysmal hemicrania and SUNCT) are a primary headache grouped characterized by the presence of unilateral pain in the somatic distribution of the trigeminal nerve, associated with craniofacial ipsilateral autonomic features. Despite their common elements, individually these headaches differ with respect to attack duration, frequency, and response to indomethacin.A three cases of TACs of dentomaxilar location is presented, common and particular characteristics, and the need for differential diagnosis with pain from stomatognathic structures.

Hemicránea paroxística de localización dentomaxilar: reporte deun Caso / Dento maxilar paroxysmal hemialgia: case report

La hemicránea paroxística es un cuadro de cefalea primaria, agrupada dentro de las Cefaleas Trigémino Autonómicas(CTAs), junto con la cefalea cluster y el SUNCT, caracterizada por la presencia de dolor unilateral en la distribución somática del nervio trigeminal y asociada a características autonómicas craneofaciales ipsilaterales. A pesar de sus elementos comunes, de forma individual, difieren con respecto a su duración, frecuencia y la respuesta a indometacina. Se presenta un caso de hemicránea paroxística de localización primaria dentomaxilar, sus características comunes y particulares respecto de las demás CTAs, y la necesidad del diagnóstico diferencial con cuadros dolorosos provenientes de estructuras estomatognáticas.

Paroxysmal hemialgia is a primary cephalea of the AutonomousTrigeminus Cephaleas type (ATCs) along with cluster cephalea and SUNCT characterized by the presence of unilateral pain in the somatic distribution of the trigeminal nerve associated to autonomous craniofacial ipsilateral characteristics. Despite the common elements, individually they differ with respect to the length, frequency and response to indomethacin. We present a primary location dento maxilar paroxysmal hemialgia case, its common and particular characteristics with respect to all other ATCs and the need to a differential diagnose with pain coming from stomatognathic structures.

Black, white and shades of grey: SUNCT or short-lasting chronic paroxysmal hemicrania? / Preto, branco e tons de cinza: SUNCT ou hemicrania paroxística crônica de curta duração?

AIM OF THE STUDY: To report a case of unilateral headache with two possibilities of diagnosis. METHOD: Case report. RESULTS: Patient with unilateral, intense, stabbing periocular headache with conjuntival injection and tearing. Although the duration of attacks was typical of SUNCT, there was complete remission of the pain with indomethacin, suggesting that this was a case of chronic paroxysmal hemicrania with unusually short attack duration. CONCLUSION: Therapeutic trials of indomethacin on younger patients presenting clinical diagnosis of SUNCT could be tried on a more regular basis.

MOTIVO DO ESTUDO: Relatar um caso de cefaléia unilateral com duas possibilidades diagnósticas. MÉTODOS: Relato de caso. RESULTADOS: Paciente com cefaléia unilateral, intensa, em pontadas em região periocular, com congestão conjuntival e lacrimejamento. Embora a duração das crises fosse típica de SUNCT, houve remissão completa da dor com indometacina, sugerindo que se trate de um caso de hemicramia paroxística crônica com crises de duração atipicamente muito curta. CONCLUSÃO: Testes terapêuticos com indometacina em pacientes mais jovens com diagnóstico clínico de SUNCT poderiam ser tentados de forma mais regular.
