RESUMO
OBJECTIVE: To investigate the relationship between pain extent, as a clinical sign of central sensitization, and clinical, psychological, and pressure sensitivity in women with fibromyalgia syndrome (FMS). METHOD: In this study, 126 females with FMS completed demographic (age, gender, body mass index, height, weight), clinical (pain history, and pain intensity at rest and during daily living activities), psychological (depression and anxiety levels), and neurophysiological [pressure pain threshold (PPT)] assessments. The Central Sensitization Inventory (CSI) was also used to collect self-reported symptoms of sensitization. Pain extent and frequency maps were obtained from pain drawings using customized software. After conducting a multivariable correlation analysis to determine the relationships between variables, a stepwise linear regression model analysis was performed to identify variables associated with pain extent. RESULTS: Pain extent was positively associated with age (r = 0.17), years with pain (r = 0.27), pain during daily life activities (r = 0.27), and CSI (r = 0.42) (all p < 0.05). The stepwise regression analysis revealed that 27.8% of the pain extent was explained by CSI, age, and years with pain. CONCLUSIONS: This study found that larger pain extent was associated with self-reported outcomes, i.e. CSI, but not neurophysiological outcomes, i.e. PPTs, of sensitization in women with FMS. Older age and a longer history with pain symptoms were also associated with larger pain extent.

BACKGROUND: Myogenic temporomandibular disorders (MTMD) frequently coexist with other clinical conditions in the same individual. In the last decades, several authors have analyzed these comorbidities looking for the origin of this overlapping. Objetives: The aim of this study was to perform a comparative anaylisis between a group of patients with MTMD and a control group of dental patients without dysfunctional pathology to assess whether there are significant differences in the presence of systemic medical comorbidities between the two groups. MATERIAL AND METHODS: Restrospective epidemiological analysis, based on medical questionnaires in a group of 31 patients, women, aged from 24 to 58 (average 39.96 years), diagnosed with MTMD (Masticatory Myofascial Pain), with a control group with the same number of individuals, gender and age range to evaluate if there is a significant statistical difference in the presence of medical comorbidities in this group of patients with MTMD and if they are in a higher risk of suffering different pathological conditions. RESULTS: It was found that the group affected by MTMD presented many more associated medical conditions than the control group: health changes during the last year, medical evaluations and treatments, presence of pain, sinus disease, tinnitus, headache, joint pain, ocular disorders, fatigue, dizziness, genitourinary disorders and xerostomia among others; and they were also in a higher risk to suffer other pathological entities as headaches and articular pain. CONCLUSIONS: These results reinforce our hypothesis that MTMD belong to a group of medical conditions triggered by a loss of equilibrium of the individual's Psycho-Neuro-Endocrine-Immune (PNEI) Axis that produces alterations in the response against external stimuli in some genetically predisposed individuals. It is, therefore, necessary to change the way of diagnosing and managing these individual's medical conditions, being mandatory to look from a more multidisciplinary perspective than the one we are currently offering.

OBJECTIVES: To study the efficacy of manual therapy in the treatment of tension-type headache (TTH) by assessing the quality of randomized control trials (RCTs) published from the year 2000 to April 2013. METHODS: A search was performed in the following databases: MEDLINE, EBSCO, CINAHL, SCOPUS, PEDRO and OVID. An analysis was made of RCT including patients with TTH receiving any manual therapy, and assessing outcome measures including the intensity, and frequency or duration of the headache. Two independent referees reviewed the methodological quality of RCTs using the Jadad scale. Data from the studies were extracted by two different reviewers. RESULTS: A total of fourteen RCTs were selected. Twelve studies showed acceptable quality (Jadad scale ≥3), and the remaining 2 had low quality (Jadad=2). The studies showed positive results, including reduction in headache intensity and/or frequency, reduction of medication consumption, and improvement in quality of life. CONCLUSIONS: The effectiveness of manual therapy for TTH cannot be completely assessed due to the heterogeneity in study design, outcome measures, and different treatments. Nevertheless, the results suggest patients with TTH receiving manual therapies showed better progress than those receiving conventional treatment or placebo. Further studies of high quality using manual therapy protocols, and also including standardized outcome measures, are now needed to clarify the efficacy of manual therapy in the management of TTH.

OBJECTIVE: To examine the associations between function, quality of life, personality, cognitive and psychological outcomes with fatigue in patients with MS. METHODS: One hundred and eight patients (54% women) with definite MS participated. MS-related fatigue was assessed with the Fatigue Impact Scale (FIS). Demographic and clinical data (weight, height, medication and history of pain), specific disease outcomes (Functional Assessment of Multiple Sclerosis/FAMS), general disease outcomes (Beck Depression Inventory/BDI-II, and Short-Form Health Survey 36/SF-36) and personality (NEO Five-Factor Inventory/NEOFFI) were assessed. Correlation and regression analyses were performed to determine associations between variables. RESULTS: A significant positive correlation existed between the FIS and EDSS (r=0.190; P<0.05). Significant negative correlations between the FIS with specific disease (FAMS mobility: r=-0.333, P<0.01; FAMS symptoms: r=-0.443, P<0.01; FAMS emotional well-being: r=-0.412, P<0.01; FAMS general contentment: r=-0.325, P<. 01; and, FAMS thinking/fatigue: r=-0.706, P<0.01); general disease (all domains SF36: -0.508Assuntos

RESUMO
BACKGROUND: Neck pain is common among individuals with migraine, but there is a lack of information of how this comorbidity can be associated with cervical muscle function. This controlled cross-sectional study aimed to compare cervical muscle function, activity, and sensitization in women with migraine, neck pain, both, and neither. METHODS: This study included women, between 18 and 55 years old, with either episodic migraine with or without aura, without any concomitant headache diagnosis; chronic neck pain, with at least moderate intensity and mild disability; or neither headache nor neck pain. Pain pressure threshold, allodynia, muscle strength, and endurance and cervical muscles activity were evaluated. RESULTS: One hundred subjects, with mean age of 30.4 years old, were stratified by diagnosis (n = 25 per group) and by self-reported pain during tests. Lower endurance during flexion was observed for migraine and neck pain (34s) relative to neck pain alone (45s), migraine (40s), and controls (58s) (p = 0.04). For extensor endurance, means were 142s, 166s, 215s, and 270s, respectively (p < 0.001). Endurance times were impacted by the presence of test-induced pain decreasing about 40%-53% of the performance. Diagnostic groups did not differ significantly in strength (p > 0.05), but all pain groups presented significantly higher proportion of test-induced pain, lower muscle activity during the maximal isometric voluntary contractions, and lower pressure pain thresholds. CONCLUSION: Patients with migraine, chronic neck pain, and the association of both present altered cervical muscle function and activity. Also, test-induced pain impacts significantly on neck muscles endurance. SIGNIFICANCE: The diagnosis of migraine and chronic neck pain is associated with altered function and activity of the cervical muscles. However, the test-induced pain had an important contribution to worse cervical muscle endurance. This suggests that the therapeutic approach should focus on de-sensitization of the trigeminal-cervical complex when dealing with the comorbidity of migraine and cervical pain.

Our aim was to investigate the presence of mechanical hypersensitivity and active trigger points (TrPs) in the neck-shoulder muscles in elite swimmers with/without unilateral shoulder pain. Seventeen elite swimmers with shoulder pain; 18 swimmers without shoulder pain; and 15 elite athletes matched controls were recruited. Pressure pain thresholds (PPT) were assessed over the levator scapulae, sternocleidomastoid, upper trapezius, infraspinatus, scalene, subscapularis and tibialis anterior muscles. TrPs in the levator scapulae, upper trapezius, infraspinatus, scalene, sternocleidomastoid and subscapularis muscles were also explored. Swimmers with shoulder pain showed significant lower PPT in all muscles compared with controls (P<0.01). No differences in PPT were found between swimmers with and without shoulder pain, underlining widespread mechanical hypersensitivity. The mean number of TrPs for elite swimmer with and without shoulder pain was, respectively, 4.7 ± 1 (2.1 ± 1.5 active; 2.6 ± 1.4 latent) and 4.7 ± 1.3 (1.3 ± 1.3 active; 3.4 ± 1.5 latent), whereas healthy athletes only showed latent TrPs (2.4 ± 1.2). Elite swimmers with shoulder pain showed higher number of active TrPs than swimmers without pain, whereas it was the opposite for the number of latent muscle TrP (P<0.05). The reported mechanical hypersensitivity suggests that active TrPs play a role in the development of shoulder pain in elite swimmers.

This paper proposes 'QuickPIPER', a 15-item, validated one-dimensional model representing cancer-related fatigue, based on factor analysis testing of the Piper Fatigue Scale-revised (R-PFS). One hundred and eleven breast cancer survivors participated in this prospective, observational study of the QuickPIPER validation. Participants completed the R-PFS and the Profile of Mood States (POMS) Fatigue and Vigor subscales. The questionnaires were tested concurrently before and after a multimodal exercise programme trial. Psychometric characteristics assessed from the sample included internal consistency and factor analysis, concurrent criterion validity and predictive ability. The results shows that the correlation matrix for the QuickPIPER questionnaire was determined as suitable with the Kaiser-Meyer-Oklin values (0.89) and Bartlett's Test of Sphericity (P < 0.001). The total cumulative variance explained was 65.32%. The goodness-of-fit indices of confirmatory factor analysis were satisfactory (normed fit index = 0.91 and comparative fit index = 0.92). Test-retest reliability was very good (r = 0.947, P < 0.001). The QuickPIPER scores correlated with POMS Fatigue (r = 0.800) and POMS Vigor (r = -0.352) subscales. Predictive ability showed that the area under the curves for the screening questionnaires was 0.743 (95% confidence interval 0.579-0.906). The 15-item QuickPIPER possesses similar properties to the 22-item R-PFS and offers the important advantage of brevity.

INTRODUCTION: Headache is a frequent symptom at the acute phase of coronavirus disease 2019 (COVID-19) and also one of the most frequent adverse effects following vaccination. In both cases, headache pathophysiology seems linked to the host immune response and could have similarities. We aimed to compare the clinical phenotype and the frequency and associated onset symptoms in patients with COVID-19 related-headache and COVID-19 vaccine related-headache. SUBJECTS AND METHODS: A case-control study was conducted. Patients with confirmed COVID-19 infection and COVID-19-vaccine recipients who experienced new-onset headache were included. A standardised questionnaire was administered, including demographic variables, prior history of headaches, associated symptoms and headache-related variables. Both groups were matched for age, sex, and prior history of headache. A multivariate regression analysis was performed. RESULTS: A total of 238 patients fulfilled eligibility criteria (143 patients with COVID-19 related-headache and 95 subjects experiencing COVID-19 vaccine related-headache). Patients with COVID-19 related-headache exhibited a higher frequency of arthralgia, diarrhoea, dyspnoea, chest pain, expectoration, anosmia, myalgia, odynophagia, rhinorrhoea, cough, and dysgeusia. Further, patients with COVID-19 related-headache had a more prolonged daily duration of headache and described the headache as the worst headache ever experienced. Patients with COVID-19 vaccine-related headache, experienced more frequently pain in the parietal region, phonophobia, and worsening of the headache by head movements or eye movements. CONCLUSION: Headache caused by SARS-CoV-2 infection and COVID-19 vaccination related-headache have more similarities than differences, supporting a shared pathophysiology, and the activation of the innate immune response. The main differences were related to associated symptoms.
TITLE: Diferencias y similitudes entre la cefalea relacionada con la COVID-19 y la cefalea relacionada con la vacuna de la COVID-19. Un estudio de casos y controles.Introducción. La cefalea es un síntoma frecuente en la fase aguda de la enfermedad por coronavirus 2019 (COVID-19) y también uno de los efectos adversos más comunes tras la vacunación. En ambos casos, la fisiopatología de la cefalea parece estar relacionada con la respuesta inmunitaria del huésped y podría presentar similitudes. Nuestro objetivo fue comparar el fenotipo clínico y la frecuencia de los síntomas asociados y los síntomas de inicio en pacientes con cefalea relacionada con la COVID-19 y cefalea relacionada con la vacuna de la COVID-19. Sujetos y métodos. Se realizó un estudio de casos y controles. Se incluyó a pacientes con infección confirmada por COVID-19 y receptores de la vacuna de la COVID-19 que experimentaron un nuevo inicio de cefalea. Se administró un cuestionario estandarizado que incluyó variables demográficas, antecedentes previos de cefaleas, síntomas asociados y variables relacionadas con la cefalea. Ambos grupos se emparejaron por edad, sexo y antecedentes previos de cefaleas. Se realizó un análisis de regresión multivariante. Resultados. Un total de 238 pacientes cumplieron con los criterios de elegibilidad (143 pacientes con cefalea relacionada con la COVID-19 y 95 sujetos con cefalea relacionada con la vacuna de la COVID-19). Los pacientes con cefalea relacionada con la COVID-19 presentaron una mayor frecuencia de artralgia, diarrea, disnea, dolor torácico, expectoración, anosmia, mialgia, odinofagia, rinorrea, tos y disgeusia. Además, los pacientes con cefalea relacionada con la COVID-19 experimentaron una duración diaria más prolongada de la cefalea y describieron la cefalea como la peor que habían experimentado. Los pacientes con cefalea relacionada con la vacuna de la COVID-19 experimentaron con más frecuencia dolor en la región parietal, fonofobia y empeoramiento de la cefalea por movimientos de la cabeza o de los ojos. Conclusión. La cefalea causada por la infección por el SARS-CoV-2 y la cefalea relacionada con la vacunación de la COVID-19 presentan más similitudes que diferencias, lo que respalda una fisiopatología compartida y la activación de la respuesta inmunitaria innata. Las principales diferencias estuvieron relacionadas con los síntomas asociados.

The aim of the current study was to investigate the relationship between pressure pain thresholds, shoulder movement, mood state, pain perception, muscle endurance, quality of life and fatigue in breast cancer survivors (BCS). Fifty-nine BCS reporting fatigue were examined at 6 months post-treatment. Women completed the Piper Fatigue Scale, the Breast Cancer-Specific Quality of Life Questionnaire, the Profile of Mood State, and neck-shoulder visual analogue scale. Additionally, shoulder flexion range of motion, the McQuade test (trunk flexor endurance) and pressure pain thresholds over the C5-C6 joint, the deltoid muscle, the second metacarpal and tibialis anterior muscle were assessed. Fatigue was greater in those patients with higher depression (r= 0.45, P < 0.05), higher shoulder pain (r= 0.39, P < 0.05), higher neck pain (r= 0.46, P < 0.01), lower body image (r=-0.34, P < 0.05) and reduced shoulder movement (r=-0.32, P < 0.05). Regression analyses demonstrated that depression, cervical pain intensity, body image and shoulder mobility were associated with fatigue (r= 0.55, P < 0.001). A psychological state characterised with higher depression and reduced body image and a physical impairment with higher cervical pain intensity and reduced shoulder mobility confirm multidimensional character of fatigue in BCS.

Spatial changes in pressure pain hypersensitivity are present throughout the cephalic region (temporalis muscle) in both chronic tension-type headache (CTTH) and unilateral migraine. The aim of this study was to assess pressure pain sensitivity topographical maps on the trapezius muscle in 20 patients with CTTH and 20 with unilateral migraine in comparison with 20 healthy controls in a blind design. For this purpose, a pressure algometer was used to assess pressure pain thresholds (PPT) over 11 points of the trapezius muscle: four points in the upper part of the muscle, two over the levator scapulae muscle, two in the middle part, and the remaining three points in the lower part of the muscle. Pressure pain sensitivity maps of both sides (dominant/non-dominant; symptomatic/non-symptomatic) were depicted for patients and controls. CTTH patients showed generalized lower PPT levels compared with both migraine patients (P = 0.03) and controls (P < 0.001). The migraine group had also lower PPT than healthy controls (P < 0.001). The most sensitive location for the assessment of PPT was the neck portion of the upper trapezius muscle in both patient groups and healthy controls (P < 0.001). PPT was negatively related to some clinical pain features in both CTTH and unilateral migraine patients (all P < 0.05). Side-to-side differences were found in strictly unilateral migraine, but not in those subjects with bilateral pain, i.e. CTTH. These data support the influence of muscle hyperalgesia in both CTTH and unilateral migraine patients and point towards a general pressure pain hyperalgesia of neck-shoulder muscles in headache patients, particularly in CTTH.

Nummular headache (NH) is characterized by focal pain fixed within a small round or elliptical area of the head surface. Sensory dysfunction is apparently restricted to the symptomatic area, but a thorough analysis of cranial pain sensitivity has not been performed. Pressure pain sensitivity maps were constructed for 21 patients with NH and 21 matched healthy controls. In each subject pressure pain thresholds (PPT) were measured on 21 points distributed over the scalp. In each patient PPT were also measured in the symptomatic area and at a non-symptomatic symmetrical point. In both groups an anterior to posterior gradient was found on each side, with no significant differences of PPT measurements between sides or groups. In patients with NH, only the symptomatic area showed a local decrease of PPT (significant in comparison with the non-symptomatic symmetrical point, P < 0.001). These findings further support that NH is a non-generalized disorder with a peripheral source.

Nummular headache (NH) has been defined as a focal head pain that is exclusively felt in a small area of the head surface. Here we describe three patients who presented with focal head pain in two separate areas. This finding seems to be consistent with bifocal NH and further enlarges the clinical diversity of this headache disorder. The pathogenic mechanisms of NH may be active in multiple cranial areas in some particular patients.

Previous studies on pressure pain sensitivity in patients with migraine have shown conflicting results. There is emerging evidence suggesting that pain sensitivity is not uniformly distributed over the muscles, indicating the existence of topographical changes in pressure pain sensitivity. The aim of this study was to calculate topographical pressure pain sensitivity maps of the temporalis muscle in a blind design in patients with strictly unilateral migraine compared with controls. For this purpose, an electronic pressure algometer was used to measure pressure pain thresholds (PPT) over nine points of the temporalis muscle: three points in the anterior, medial and posterior parts, respectively. Pressure pain sensitivity maps of both sides (dominant or non-dominant; symptomatic or non-symptomatic) were calculated. The analysis of variance showed significant differences in PPT values between both groups (F = 279.2; P < 0.001) and points (F = 4.033; P < 0.001). Patients showed lower PPT at all nine points than healthy controls (P < 0.001). We also found lower PPT in the centre of the muscle compared with the posterior part of the muscle within both groups (P < 0.01). Interaction between group and points (F = 1.9; P < 0.05) was also found. Within the migraine group, PPT levels were decreased bilaterally from the posterior to the anterior column of the temporalis muscle (Student-Newman- Keuls analysis; P < 0.05), with the most sensitive in the anterior part of the muscle. For controls, PPT did not follow such anatomical distribution, the most sensitive point being the centre of the mid-muscle belly. This study showed bilateral sensitization to pressure in unilateral migraine, suggesting the involvement of central components.

No studies have investigated the effects of the treatments directed at the cervical spine in patients with temporomandibular disorders (TMD). Our aim was to investigate the effects of joint mobilization and exercise directed at the cervical spine on pain intensity and pressure pain sensitivity in the muscles of mastication in patients with TMD. Nineteen patients (14 females), aged 19-57 years, with myofascial TMD were included. All patients received a total of 10 treatment session over a 5-week period (twice per week). Treatment included manual therapy techniques and exercise directed at the cervical spine. Outcome measures included bilateral pressure pain threshold (PPT) levels over the masseter and temporalis muscles, active pain-free mouth opening (mm) and pain (Visual Analogue Scale) and were all assessed pre-intervention, 48 h after the last treatment (post-intervention) and at 12-week follow-up period. Mixed-model anovas were used to examine the effects of the intervention on each outcome measure. Within-group effect sizes were calculated in order to assess clinical effect. The 2 x 3 mixed model anova revealed significant effect for time (F = 77.8; P < 0.001) but not for side (F = 0.2; P = 0.7) for changes in PPT over the masseter muscle and over the temporalis muscle (time: F = 66.8; P < 0.001; side: F = 0.07; P = 0.8). Post hoc revealed significant differences between pre-intervention and both post-intervention and follow-up periods (P < 0.001) but not between post-intervention and follow-up period (P = 0.9) for both muscles. Within-group effect sizes were large (d > 1.0) for both follow-up periods in both muscles. The anova found a significant effect for time (F = 78.6; P < 0.001) for changes in pain intensity and active pain-free mouth opening (F = 17.1; P < 0.001). Significant differences were found between pre-intervention and both post-intervention and follow-up periods (P < 0.001) but not between the post-intervention and follow-up period (P > 0.7). Within-group effect sizes were large (d > 0.8) for both post-intervention and follow-up periods. The application of treatment directed at the cervical spine may be beneficial in decreasing pain intensity, increasing PPTs over the masticatory muscles and an increasing pain-free mouth opening in patients with myofascial TMD.

To date the effects of physical therapy or exercise in headaches has hardly been analysed. Conflicting results in previous studies might be due to the low number of clinical trials plus an indiscriminate application of different techniques. As different pathogenic mechanisms seem to be involved in each headache, the most appropriate techniques might differ in each case. Future research should address the evaluation of specific physical therapy procedures for each headache disorder, and the identification of those subgroups of patients who are most likely to benefit from a particular intervention.

The purpose of the study was to compare the co-activation of cervical agonist and antagonist muscles between people with chronic tension-type headache (CTTH) and healthy controls during brief isometric cervical flexion and extension contractions. Nine women with CTTH and 10 matched controls participated. Surface electromyographic (EMG) signals were detected from the sternocleidomastoid and splenius capitis muscles bilaterally during cervical flexion and extension contractions of linearly increasing force from 0% to 60% of the maximum voluntary contraction (MVC) in 3 s. Sternocleidomastoid and splenius capitis EMG average rectified values (ARV) were estimated at 10% MVC force increments. During cervical extension contraction, sternocleidomastoid (i.e. antagonist muscle) ARV was greater for patients than for controls in the force range 20-60% MVC (P = 0.029). During cervical flexion, the left splenius capitis (i.e. antagonist muscle) ARV was greater for CTTH patients regardless of the force level (P = 0.02). Maximum cervical flexion and extension force was lower for the CTTH patients compared with controls (P = 0.001). In conclusion, women with CTTH demonstrated greater co-activation of antagonist musculature during cervical extension and flexion contractions compared with healthy women. Increased co-activation of antagonist musculature may reflect reorganization of the motor control strategy in CTTH patients, potentially leading to muscle overload and increased nociception.

Cephalic and extracephalic allodynia are recognized as a common sign of sensory sensitization during migraine episodes. However, the occurrence of body pain in migraine has not been thoroughly explored. Here we report three patients presenting with spontaneous body pain in association with migraine attacks. A 41-year-old woman experienced face and limb pain along with migraine headaches; it started before, during or after headache, was usually ipsilateral to head pain, and could last from minutes to days. A 39-year-old woman had pain in her right limbs, back and neck for 30-60 min prior to right-sided migraine headaches. A 30-year-old woman perceived pain in her left upper limb for 24-48 h prior to left-sided migraine headaches. All patients had allodynia to mechanical stimuli over the painful areas. Spontaneous body pain may be associated with migraine attacks. Together with allodynia, this might be a consequence of central sensitization.

To date, no studies have investigated the predictive validity of variables from the initial examination to identify patients with tension-type headache pain who are likely to benefit from muscle trigger point (TrP) therapy. The purpose of this study was to develop a preliminary clinical prediction rule (CPR) to identify chronic tension-type headache (CTTH) patients who are likely to experience a successful response from TrP therapy. Consecutive patients with CTTH underwent a standardized examination and then received six sessions of TrP therapy over 3 weeks (two sessions per week). They were classified as having experienced a successful outcome at short-term (1 week after discharge) and 1-month follow-up based on a 50% reduction on at least one headache parameter (intensity, frequency or duration) and self-report perceived recovery. Potential predictor variables were entered into a stepwise logistic regression model to determine the most accurate set of variables for identifying treatment success. Data from 35 patients were included, of which 19 (55%) experienced a successful outcome. A CPR with four variables for short-term (headache duration < 8.5 h/day, headache frequency < 5.5 days/week, bodily pain < 47 and vitality < 47.5) and a CPR with two variables for 1-month (headache frequency < 5.5 days/week and bodily pain < 47) follow-up were identified. At short-term follow-up, if three of four variables [positive likelihood ratio (LR) 3.4] were present, the chance of experiencing a successful outcome improved from 54% to 80%, and if all the variables (positive LR 5.9) were present, the probability of success was 87.4%. At 1-month follow-up, if one of two variables (positive LR 2.2) was present, the probability of success increased from 54% to 72%, and if both variables (positive LR 4.6) were present, the probability of success was 84.4%. The present CPR provides the potential to identify CTTH patients who are likely to experience short-term and 1-month follow-up success with a muscle TrP therapy approach. Future studies are necessary to validate the CPR.

Ten patients (one man and nine women, mean age 48.8 +/- 20.1) presented with a stereotypical and undescribed type of head pain. They complained of strictly unilateral, shooting pain paroxysms starting in a focal area of the posterior parietal or temporal region and rapidly spreading forward to the ipsilateral eye (n = 7) or nose (n = 3) along a lineal or zigzag trajectory, the complete sequence lasting 1-10 s. Two patients had ipsilateral lacrimation, and one had rhinorrhoea at the end of the attacks. The attacks could be either spontaneous or triggered by touch on the stemming area (n = 2), which could otherwise remain tender or slightly painful between the paroxysms (n = 5). The frequency ranged from two attacks per month to countless attacks per day, and the temporal pattern was either remitting (n = 5) or chronic (n = 5). This clinical picture might be a variant of an established headache or represent a novel syndrome.
