A high-urgency stroke code reduces in-hospital delays in acute ischemic stroke: a single-centre experience.

Timely treatment is essential in acute ischemic stroke as the chances of recovery diminish over time, so efforts are necessary to streamline in-hospital pathways and reduce delays. Here, we analyse the interventions to reduce door-to-needle time in stroke patients suitable for intravenous thrombolysis at the Emergency Department of San Carlo Borromeo Hospital, Milan, Italy. All stroke patients consecutively treated with intravenous thrombolysis at our centre from January 1, 2013 to December 31, 2015 were included in this analysis. The main interventions adopted were (1) continuous education of personnel, (2) reconsideration of blood tests and identify the ones really affecting treatment decision, (3) approval of a new high-urgency Stroke Code activated as soon as the triage nurse comes to know of a potential thrombolysis candidate. Median door-to-needle time progressively decreased from 103 min (iqr 78-120) in 2013, to 92 min (iqr 72-112) in 2014, and to 37 min (iqr 27-58) with the new Stroke Code (p < 0.001) in 2015. Simultaneously, median onset-to-treatment time decreased from 177 min (iqr 142-188) in 2013, to 155 min (iqr 141-198) in 2014, and to 114 min (iqr 86-160) with the new Stroke Code (p < 0.001 and p 0.005, respectively). We did not observe any significant difference in bleeding risks or deaths, whereas the likelihood of favourable outcome (mRS 0-2) increased. Streamlining in-hospital pathways with progressive interventions significantly decreases door-to-needle time and onset-to-treatment time and may contribute to improve stroke outcomes.

Migraine with aura white matter lesions: preliminary data on clinical aspects.

A few clinic-based magnetic resonance imaging studies report an increased risk of signal abnormalities in migraineurs brain's white matter, especially in migraine with aura subjects. A vascular genesis has been hypnotized and migraine with aura was considered an independent risk factor for stroke. Available data of magnetic resonance imaging alterations are often nonspecific and sometimes controversial. The aim of our study is to investigate migraine with aura patients with standardized brain magnetic resonance imaging to detect and to quantify the presence of white matter lesions and to analyze their relation with clinical data. We report preliminary data about first 90 subjects. We did not recognize any clinical aspect in close relationship with these alterations. The only clinical feature that seems to play a role in the presence of alterations is the age, and only in migraineurs women.

Electromyography data in chronic migraine patients by using neurostimulation with the Cefaly® device.

The objective of this observational study is to report clinical and instrumental results obtained in 23 chronic migraine sufferers treated with transcutaneous neurostimulation with the Cefaly(®) device. The electrom yography (EMG) parameters of the patients monitored before and during neurostimulation with the Cefaly(®) device showed a significant increase in the EMG amplitude and frequency values in the frontalis, anterior temporalis, auricularis posterior and middle trapezius muscles. The Cefaly(®) device could act on the inhibitory circuit in the spinal cord thus causing a neuromuscular facilitation and may help reduce contraction of frontalis muscles.

Headache, eating and sleeping behaviors and lifestyle factors in preadolescents and adolescents: preliminary results from an Italian population study.

Several dietary and lifestyle habits can be associated with headaches or with their progression to chronic forms in adults. We report the results of the first population study performed in Italy on a sample of preadolescent and adolescent students to assess the possible association between headache and specific habits and lifestyle factors. Preliminary data from 800 questionnaires showed that 365 subjects had headaches, which were of moderate-severe intensity, associated with anorexia, and caused absence from school in more than 50 % of students. The main finding was the evidence of a clear association between headache and irregular intake of meals (especially irregular breakfast) and sleep disturbance with significant differences when subjects with and without headache were compared. If confirmed, these results are likely to influence clinical practice as well to address educational programs in preadolescents and adolescents.

Headache at high school: clinical characteristics and impact.

Although migraine (MH) and tension type headache (TTH) are the most common and important causes of recurrent headache in adolescents, they are poorly understood and not recognized by parents and teachers, delaying the first physician evaluation for correct diagnosis and management. The purpose of this study is to assess the knowledge about headache impact among the students of a Communication Private High School in Rimini city, and to evaluate the main different types of headaches interfering with school and social day activities. A self-administered questionnaire interview was given to students of the last 2 years of high school; ten items assessed the headache experience during the prior 12 months, especially during school time: the features and diagnosis of headaches types (based on the 2004 IHS criteria), precipitating factors, disability measured using the migraine disability assessment (MIDAS); therapeutic intervention. Out of the 60 students, 84 % experienced recurrent headache during the last 12 months. 79 % were females, aged 17-20 years; a family history was present in 74 % of headache students, in the maternal line; 45 % of subjects were identified as having MH and 27 % TTH; 25 % had morning headache and 20 % in the afternoon; fatigue, emotional stress and lack of sleep were the main trigger factors for headache, respectively in 86, 50 and 50 % of students; 92 % of headache students could not follow the lessons, could not participate in exercises and physical activity because of the headache; none had consulted a medical doctor and the 90 % of all students had never read, listened or watched television about headache. This study remarks on the need to promote headache educational programs, starting from high school, to increase communication between teachers-family-physician and patient-adolescents, with the goal to have an early appropriate therapeutic intervention, improvement of the quality of life and to prevent long-term headache disease in the adult age.

Remarks on an educational training course on headache.

In the last years several studies have been performed on migraine; however, only few topics have changed the clinical practice. Among these, there are physiopathological insights (e.g., allodynia and gastric stasis) or therapeutical evidences (e.g., topiramate) that become very important in the management of migraine and could clarify the different response to the therapies. The aim of a training school on headache should be to link research to practice without transferring contradictory data. To teach is not only to support notions with simple data: we think that knowledge has to be used according to the condition of the patient and the situation in which the migraineurs live.

Frovatriptan for the prevention of postdural puncture headache.

Efficacy of 5-day treatment with oral frovatriptan 2.5 mg/die for the prophylaxis of post-dural puncture headache (PDPH) was tested in 50 in-patients. A mild headache occurred in 7 (14%) patients for a total of 9 days (p < 0.01 vs. no-PDPH). Most episodes of PDPH occurred in the first days of treatment (only 1 patient had headache at dismissal): 5 patients had only 1 episode, while 2 had headache for 2 consecutive days. No other symptoms were recorded. Occurrence of PDPH in a subgroup of 6 (12%) patients previously submitted to a diagnostic lumbar puncture was also examined: 4 of them reported a PDPH on the previous lumbar puncture in absence of triptans. In only 1 of these 4 patients PDPH recurred under treatment with frovatriptan. In conclusion, our non-randomized open-label study suggests efficacy of oral frovatriptan for PDPH prevention. These results need to be confirmed in a randomized, controlled, double-blind study.

Migraine and depression.

Investigations of migraine comorbidity have confirmed its association with diverse psychiatric conditions. This association appears to be stronger for major depression and anxiety disorders, but comorbidity has also been reported with substance abuse and certain mood disorders. This literature also indicates that greater psychiatric comorbidity exists for migraine sufferers with aura than without. There is evidence that psychiatric comorbidity is higher in transformed migraine than in episodic migraine. However, research into the possible mechanisms underlying these associations remains limited. Subjects with migraine should be carefully screened for depression, which should be managed to prevent transformation of migraine, to increase quality of life and to gain more successful migraine therapies.

Improvement in quality of life and activity limitations in migraine patients after prophylaxis. A prospective longitudinal multicentre study.

Improved health-related quality of life (HRQOL) and reduced activity limitations are prime objectives of migraine therapy, but no data on the effect of preventive treatments on these outcomes are available. We monitored changes in HRQOL using the Short Form 36 (SF-36) and headache-related activity limitations using the Migraine Disability Assessment Score (MIDAS) in 141 consecutive migraine without aura patients on prophylaxis. A total of 102 patients completed the 3-month study. Mean (SD) number of headache days/month dropped from 8.0 (3.7) to 5.0 (2.3) (P < 0.001). Mean monthly consumption of acute drugs reduced from 7.4 (3.5) to 4.4 (3.1) (P < 0.001). MIDAS total score reduced (improved) significantly. All SF-36 scale scores increased (improved), most significantly. This first study to assess prospectively the impact of prophylaxis on HRQOL and daily activities in a large series indicates that migraine prophylaxis has the potential to reduce the global burden of migraine on individuals and society.

Pharmacological therapy of atypical facial pain: actuality and perspective.

Atypical facial pain is a condition, which creates a difficult challenge for every physician, either for diagnosis or for choice of treatment. There are very few controlled studies and evidence-based data about what constitutes the gold standard treatment. Most physicians treat this condition with antidepressant agents, thinking that the psychiatric aspects, often present in these patients, play a fundamental role in the pathogenesis of the condition. However, antidepressant drugs are effective also in non-psychiatric patients, and new compounds, with no effect on psychological aspects, have recently seemed to show good activity in controlling pain in this disorder. We review the different possibilities available for treating this frustrating condition.

Anticonvulsant drugs in primary headaches prophylaxis.

Anticonvulsant drugs have been used in migraine prophylaxis since 1970. In recent years, new antiepileptic medications have given rise to much interest in pain control. Primary headaches prophylaxis is still based on old drugs, and physicians facing these conditions are always prompted to use any new possible choice. Among primary headaches, the most studied drug over last 15 years was divalproex sodium, and many papers showed its efficacy in the treatment of migraine headaches. Valproate is well tolerated and many dosages have been used with success. For the newer drugs, such as gabapentin, lamotrigine or topiramate, evidence is less strong but has been rapidly increasing in the last 5 years. In particular, topiramate has much more evidence of a good efficacy and a safe profile. We review the principal characteristics of their use, according to dosages, lasting of treatments, side effects and significant efficacy.

Measure of negative impact of migraine on daily activities, social relationships and therapeutic approach.

The study has been conducted in 9 European countries, interviewing 200 women in each country, aged 18-35, in fully working or studying period, to get a total of 1810 people. Migraine or severe headache was recognised and patients were studied to understand their behaviour. The features and severity of headache, the use of different drugs, the relationship between physicians and patients, the disability during attacks, the psychological aspects and the feeling of impotence that migraine patients experienced during their lives, are analysed and reported.

Psychological and emotional aspects and pain.

A patient's psychological condition can be influenced by symptoms and, at the same time, it can influence the perception of symptoms. In psychological assessment, pain can modify the results of a questionnaire, so a patient's state at the moment of the evaluation should be taken into account. Questionnaires used in assessment do not always provide clear-cut answers concerning the individual psychological component. Moreover, difficulties in classifying headache patients does not permit correct comparisons between population samples whenever patients are not classified into well defined homogeneous groups. Overall, in the three groups examined - migraine, tension-type headache and cluster headache - it can be affirmed that with self-report assessment based on questionnaires, the tension-type headache subjects present a more interesting psychological profile for its clinical implications.

The patient with medication overuse: clinical management problems.

Patients with chronic headache arise many problems in clinical management, often strictly related to medication overuse. IHS classification did not clear the different clinical presentation and a chapter dedicated to this problem is lacking. This condition is very frequently associated with psychiatric illness, so that the clinical features become more complex over the years. Most of patients share a past clinical condition of episodic migraine; this aspect is very important facing the therapeutical phase, because after discontinuing medication overuse, if present, the treatment must be direct toward this disease. To treat a patient with analgesic, or ergotamine, or triptan abuse, require much caution because stopping the drug may arise new problems, such as different headache, abstinence syndrome, epileptic seizures etc. We review the different possibility that we have to manage the overuser patient.

Migraine with aura and white matter abnormalities: Notch3 mutation.

The authors report on an Italian family with eight affected members who show autosomal dominant migraine with prolonged visual, sensory, motor, and aphasic aura. These symptoms are associated with white matter abnormalities on brain MRI. All living affected members carry a Notch3 mutation (Arg153Cys) previously reported in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). White matter abnormalities occur in a variable percentage of the general migraine population; CADASIL should be suspected in migraineurs with prolonged atypical aura and white matter abnormalities.

Verapamil in the prophylaxis of episodic cluster headache: a double-blind study versus placebo.

The authors performed a double-blind, double-dummy study to compare the efficacy of verapamil with placebo in the prophylaxis of episodic cluster headache. After 5 days' run-in, 15 patients received verapamil (120 mg tid) and 15 received placebo (tid) for 14 days. The authors found a significant reduction in attack frequency and abortive agents consumption in the verapamil group. Side effects were mild. These findings provide objective evidence for the effectiveness of verapamil in episodic cluster headache prophylaxis.

Quantification of headache disability: a diagnostic-based approach.

The quantification of the social and economic handicaps caused by headache is a complex problem, especially given the great variability of headache patients' clinical pictures. In the present study, 400 patients, consecutively admitted to Headache Centers in Pavia and Milan, were interviewed on the relationship between headache and their work and social activities, in order to evaluate their socioeconomic handicap due to headache. The analysis of the data primarily focused on attack-type headaches (migraine, cluster headache, and episodic tension-type headache) and chronic or daily headaches (chronic tension-type headache and migraine combined with tension-type headache). These latter types were often characterized by the daily use or abuse of analgesics. The overall profile which emerged from the study reveals relatively low levels of handicap or disability in work and social activities. These low levels can be mainly attributed to timely, and at times excessive, use of analgesics.

Clinical considerations on side-locked unilaterality in long-lasting primary headaches.

The relevance of side-locked unilateral pain (with no side shift) in diagnosing and differentiating primary long-lasting cephalgias such as tension headache and migraine is not clear. In the present study we have retrospectively examined the frequency of side-locked unilaterality in 1169 primary headache outpatients, whose pain duration was more than four hours. The cases were migraine (66%), tension-type headache (21%) and non-classifiable headache and atypical facial pain (not well defined headaches) (13%). The occurrence of side-locked unilateral pain was more frequent in migraine (17%) than tension headache (4%). However side-locked pain was found to be more frequent in patients with not-well-defined head pain (28%). Of the 1169 patients, 181 (15%) had side-locked unilateral pain: 70% of the 181 had migraine, 25% were not-well-defined head pain cases and 5% were tension-type headache cases. The high percentage of migraine cases in the side-locked unilateral group reflects the high proportion of migraine patients in the studied population.
