Although typical CH patients have one to two unilateral neuralgiform headache attacks with conjunctival injection and attacks a day, typical PH patients experience 10 and typical SUNCT/ tearing (SUNCT) or short-lasting unilateral neuralgiform headaches with SUNA patients suffer 50, there is a marked skew that favours a lower cranial autonomic symptoms (SUNA).

  • Trigeminal Autonomic Cephalalgias CQ IV-1
    IV Trigeminal autonomic cephalalgias CQ IV-1 How are trigeminal autonomic cephalalgias classified and typed? Recommendation The International Classification of Headache Disorders 3rd Edition (beta version; ICHD-3 beta) classifies cluster headache together with related diseases under “Trigeminal autonomic cephalalgias”. Furthermore, “Trigeminal autonomic cephalalgias” is further divided into five subtypes: cluster headache, paroxysmal hemicrania, short-lasting unilateral neuralgiform headache attacks, hemicrania continua and probable trigeminal autonomic cephalalgia. Grade A Background and Objective The objective of this section is to classify Trigeminal“ autonomic cephalalgias” according to the International Classification of Headache Disorders 3rd Edition (beta version; ICHD-3 beta).1)2) Comments and Evidence Cluster headache and related diseases are characterized by short-lasting, unilateral headache attacks accompanied by cranial parasympathetic autonomic symptoms including conjunctival injection, lacrimation, and rhinorrhea. These syndromes support the involvement of trigeminal-parasympathetic reflex activation, and ICHD-3 beta introduces the concept of trigeminal autonomic cephalalgias (TACs) (Table 1). TACs comprise the following subtypes: 3.1 cluster headache, 3.2 paroxysmal hemicrania, 3.3 short-lasting unilateral neuralgiform headache attacks, 3.4 hemicrania continua, and 3.5 probable trigeminal-autonomic cephalalgia.

    B. RELATIVELY LOCALIZED SYNDROMES OF THE HEAD AND NECK GROUP II: NEURALGIAS OF THE HEAD AND FACE Trigeminal Neuralgia (Tic Douloureux) (II-1) Definition Sudden, usually unilateral, severe brief stabbing recurrent pains in the distribution of one or more branches of the Vth cranial nerve. Site Strictly limited to the distribution of the Vth nerve; unilateral in about 95% of the cases. Usually involves one branch; may involve two or, rarely, even all three branches. The second, third, and first branches of the Vth cranial nerve are involved in the foregoing order of frequency. The pain is more frequent on the right side. System Nervous system. Main Features Prevalence: relatively rare. Incidence: men 2.7, women 5.0 per 100,000 per annum in USA. Most patients have a lesion compressing the nerve where it leaves the brain stem. In patients with multiple sclerosis, there is also an increased incidence of tic douloureux. Sex Ratio: women affected perhaps more commonly than men. Age of Onset: after fourth decade, with peak onset in fifth to seventh decades; earlier onset does occur, but onset before age 30 is uncommon. Pain Quality: sharp, agonizing electric shock-like stabs or pain felt superficially in the skin or buccal mucosa, triggered by light mechanical contact from a more or less restricted site (trigger point or trigger zone), usually of brief duration-a few seconds (but reportedly occasionally up to 1-2 minutes followed by a refractory period of up to a few minutes. Time Pattern: paroxysms may occur at intervals or many times daily or, in rare instances, succeed one another almost continuously.

  • Bilateral Sunct Syndrome Associated to Chronic Maxillary Sinus Disease
    Arq Neuropsiquiatr 2006;64(2-B):504-506 BILATERAL SUNCT SYNDROME ASSOCIATED TO CHRONIC MAXILLARY SINUS DISEASE Denis Bernardi Bichuetti1, Wellington Yugo Yamaoka2, João Ricardo Parrela Bastos3, Deusvenir de Souza Carvalho4 ABSTRACT - SUNCT syndrome (short lasting unilateral neuralgiform headache with conjuntival injection and tearing) is defined as short attacks of periorbital unilateral pain and accompanied by ipsilateral lacrima- tion and redness of the same eye. We present an unusual SUNCT case with bilateral pain that started five years ago after an acute maxillary sinus infection that evolved to chronic sinusitis. This association has been described in few SUNCT cases, but its causal role remains uncertain. The patient was a 58 years old man that fulfilled a headache diary that showed the usual circadian pattern, worsening in the morning and afternoon, and responded to treatment with gabapentina. He was submitted to a functional endoscopic sinus surg e ry and evolved with milder pain. In a review of 21 patients, 5 had a past medical history of sinusi- tis, but the causal role of this association remained uncertain. KEY WORDS: SUNCT, bilateral, sinusitis, gabapentina Síndrome SUNCT de ocorrência bilateral associada a sinusopatia maxilar crônica RESUMO - A síndrome SUNCT (short lasting unilateral neuralgiform headache with conjuntival injection and tearing) é definida como curtos ataques de dor periorbital unilateral, acompanhada de lacrimejamento e h i p e remia conjuntival ipsilateral.

    The Clinical, Therapeutic and Radiological Spectrum of SUNCT, SUNA and Trigeminal Neuralgia By Giorgio Lambru The Headache Group Institute of Neurology University College London London WC1N 3BG A thesis submitted in fulfillment of the requirements for the degree of Doctor of Philosophy (PhD) University of London 2018 I, Giorgio Lambru, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Dr Giorgio Lambru 1 Abstract This thesis examines and compares the demographics, clinical phenotype, radiological findings and response to medical and surgical treatments of SUNCT (short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing) and SUNA (short-lasting unilateral neuralgiform headache attacks with autonomic symptoms). Given the similarities between SUNCT, SUNA and trigeminal neuralgia (TN), the demographics and clinical phenotype of these disorders were also compared. In the first study (Chapter 2) a cohort of 133 patients (SUNA=63 and SUNCT=70) was phenotyped and the clinical characteristics of SUNA compared to those of SUNCT. Statistically significant predictors for SUNCT rather than SUNA were only found for ipsilateral ptosis [OR: 3.37 (95% CI: 1.50, 7.66), p<0.0001] and rhinorrhoea [OR: 2.42 (95% CI: 1.09, 5.41), p=0.034]. Furthermore, a significantly higher proportion of SUNCT patients (n=56, 80.0%) reported marked lacrimation compared to SUNA patients (n=20, 46.5%) (P<0.001). In the second study (Chapter 3) 45 SUNCT and 34 SUNA patients had high-resolution cisternal imaging MRI scans to asses the presence of trigeminal neurovascular conflict.

  • Case Reports 35
    Case Reports 35 Pain Relief in Short-Lasting Unilateral Neuralgiform Headache with Conjunctival inJection and Tearing Syndrome with Intravenous Ketamine: A Case Report Shunji Shiiba, Teppei Sago, Kazune Kawabata Abstract Purpose: Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) is a rare form of primary headache, classified as trigeminal autonomic cephalalgia. Since the underlying mechanism of the pathogenesis has not yet been determined, a standardized therapeutic strategy for SUNCT is unavailable. We present a case of SUNCT syndrome with successful pain relief by intravenous administration of ketamine, an N-methyl-D-aspartate receptor (NMDAR) antagonist. Case report: A 56-year-old male patient reported severe throbbing and shooting pain in forehead, temporal and periorbital region. We confirmed conjunctival injection, lacrimation, blepharoptosis, and miosis as symptoms related to autonomic activity, and made a diagnosis of SUNCT based on ICHD-3 beta. Numerous treatments were attempted, including pregabalin, gabapentine, non- steroidal antiinflammatory drugs, acetaminophen, steroids, antidepressants, triptans, nerve blocks, and intravenous lidocaine with unsatisfactory results. Intravenous administration of ketamine (0.4 mg/kg) for one hour, was found to relieve the severe pain. Conclusion: Intravenous ketamine can effectively treat SUNCT syndrome. This case demonstrated that involvement of NMDAR could be one of the mechanisms of SUNCT syndrome pathogenesis and establish a therapeutic strategy for this pain syndrome. Keywords: SUNCT; Ketamine; NMDA receptor, Trigeminal neuralgia; neuropathic pain.

Yára Dadalti Fragoso1 ABSTRACT - Aim of the study: To report a case of unilateral headache with two possibilities of diagnosis. Method: Case re p o rt . Results: Patient with unilateral, intense, stabbing periocular headache with con- juntival 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 hemicra- nia 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.
