Abstract
BACKGROUND The characteristics of primary headaches in patients with ruptured brain aneurysm embolization have not been well understood to date. AIMS OF THE STUDY This study was conducted to evaluate the influence of endovascular treatment (EVT) of ruptured intracranial aneurysm (RIA) and the pattern of previous primary headache. METHODS We evaluated the pattern of headache in patients who suffered a RIA and EVT within one year before the rupture, and prospectively evaluated the characteristics of headache for up to 12 months after EVT. Sixty patients were evaluated and a questionnaire about headache was applied at the time of admission. These patients were contacted 3, 6 and 12 months after treatment to complete the study by filling out follow-up questionnaire on the headache. RESULTS Thirty-seven patients had headache before the rupture, 16 with tension-type headache (TTH), 11 with migraine without aura, nine with migraine with aura with and one with non-specific characteristics. There was a significant reduction in the frequency of pain for up to 12 months for patients with TTH (P < 0.001) and migraine without aura (P = 0.012), but there was a reduction in pain intensity over the same period in TTH (P = 0.002), migraine with aura (P = 0.004) and migraine without aura (P < 0.001). CONCLUSION There was a reduction of the primary headache after endovascular treatment of ruptured brain aneurysm.

Abstract
The case of a 25-year-old white male, who had migrainous headaches each time he sat in front of his personal computer screen, is described. Changing the screen frequency from 60 to 75 Hz through a Windows command could abolish the headaches. In several surveys, computer screens have been reported to be a migraine trigger. We hypothesize that this environmental trigger may be related to the abnormal flicker fusion thresholds that have been described in migraineurs. It may be that modifying the frequencies of light sources, such as computer screens, could become a non-pharmacological approach to prevent migraine attacks.

Abstract
A randomized double-controlled trial involving 22 patients with Noonan syndrome (NS) and 22 normal individuals (control group) was carried out to determine the prevalence of migraine in patients with NS. The NS group consisted of 11 males aged 19.55 ± 6.11 years and 11 females aged 18.81 ± 5.47 years. The control group consisted of 11 males aged 19.55 ± 6.6 years and 11 females aged 18.81 ± 5.47 years. Seven NS-group patients reported migraine without aura (MO), and three reported probable MO (PMO). Taken together, these represent a prevalence of migraine in the NS group of 45.5%. Two control-group patients reported MO, a prevalence of 9.09%. The prevalence of migraine was significantly higher in the NS-group patients than in the controls ( P < 0.005), suggesting a positive association between NS and migraine. Nevertheless, further studies are needed to confirm our findings.

Abstract
The critical flicker frequencies (CFF) of individuals with migraine with and without aura were determined and compared to those of normal controls. Twenty-six migraine patients, 12 with aura and 14 without aura and 30 healthy controls were included. Migraineurs were tested during a migraine-free period, through both the continuous flicker method (CFM) and the forced choice method (FCM). Migraineurs presented a mean flickering fusion threshold lower than healthy controls with the CFM (40.45 vs. 44.33, respectively; P = 0.019) and with the FCM (34.16 Hz vs. 38.5 Hz, respectively, P = 0.019). Both groups of migraineurs had significantly lower thresholds as compared to controls, migraineurs with aura presenting the lowest thresholds for the fusion of flickering ( P = 0.008 and P = 0.0001 with the CFM and the FCM, respectively). Results confirmed and extended previous observations of abnormal flicker fusion thresholds in migraineurs. We hypothesize that this finding might be related to a shorter cortical stimulation silent period.

Abstract
The aim of this study was to estimate the 1-year prevalence of migraine and the degree of the association of migraine with some sociodemographic characteristics of a representative sample of the adult population of Brazil. This was a cross-sectional, population-based study. Telephone interviews were conducted on 3848 people, aged 18-79 years, randomly selected from the 27 States of Brazil. The estimated 1-year gender- and age-adjusted prevalence of migraine was 15.2%. Migraine was 2.2 times more prevalent in women, 1.5 times more in subjects with > 11 years of education, 1.59 times more in subjects with income of < 5 Brazilian Minimum Wages per month, and 1.43 times more in those who do not do any physical exercise. The overall prevalence of migraine in Brazil is 15.2%. Migraine is significantly more prevalent in women, subjects with higher education, with lower income, and those who do not exercise regularly, independently of their body mass index.

Abstract
The objectives of this study were to estimate the 1-year prevalence of chronic daily headache (CDH) and the degree of the association of CDH with some sociodemographic characteristics of the adult population of Brazil. This was a cross-sectional, population-based study. We conducted telephone interviews with 3848 people, aged 18-79 years, randomly selected from the 27 States of Brazil. The degree of the association was calculated through prevalence ratios, adjusted with Poisson regression by gender, age and some sociodemographic factors. The estimated 1-year gender- and age-adjusted prevalence of CDH was 6.9±. CDH was 2.4 times more prevalent in women, 1.72 times more in unemployed, 1.63 times more in subjects with high household income and two times greater in those who did not exercise. The overall prevalence of CDH in Brazil is high. CDH is significantly more prevalent in women, the unemployed, subjects with higher income, and in those who do not exercise.

Abstract
Thirteen subjects with trigeminal neuralgia were treated with botulinum-A neurotoxin (BoNT/A) in an open-label pilot study. After BoNT/A, visual analog scale score, surface area of pain, and therapeutic coefficient were reduced in all patients and for all branch trigeminal nerves studied. Therefore, BoNT/A is an efficient treatment. There were no major side effects. A placebo-controlled clinical trial is needed to confirm these findings.

Abstract
Cortical spreading depression was described in 1943 by Aristides Leão, a Brazilian neurophysiologist. Initially considered to be a mysterious event as it was discovered serendipitously, its nature has become progressively better known. Cortical spreading depression is now accepted as the mechanism underlying migraine aura and has became known as either Leão's spreading depression or cortical spreading depression. Recent studies have suggested a role for Leão's cortical spreading depression in the pathogenesis and symptomatology of neurologic disorders such as transient global amnesia, head injury, and cerebrovascular diseases.

AIMS To report the case of a 26 year old white man, who developed chronic meningitis and intracerebral granulomata 15 days after an episode of near drowning in a swamp. METHODS Aspergillus fumigatus was isolated from cerebrospinal fluid cultures. RESULTS The patient died 70 days after the symptoms were first noticed, and seven days after a subarachnoid haemorrhage. Aspergillus has never been reported before as a cause of intracranial infection after near drowning. CONCLUSIONS Physicians must be aware of this possibility when confronted with such a situation, because there are now effective therapeutic options for systemic aspergillosis.

Abstract
The idiopathic stabbing headache (ISH) is characterized by a stabbing pain of short duration, variable localization and an errant evolution pattern. As its biological mechanisms are unknown and the treatment options are little effective, this disorder shows a strong impact on the patient's life. Two females and one male, aged 76, 66 and 72 years, respectively, started presenting ISH within 20 days after the onset of a stroke. All the patients were treated for the ISH with celecoxib, a COX-2 specific inhibitor, with full recovery from ISH up to 6 days after it was first administered. The interruption of the drug 60 days after the treatment with celecoxib induced again the appearance of algic symptoms in two patients. We concluded that cerebrovascular diseases (CD) can lead to ISH and that the COX-2 inhibitor can be an effective prophylactic drug for ISH after CD.

Abstract
To investigate the relevance of lacking or diminished visual input on the expression of migraine, we evaluated its prevalence and clinical features in a population of visually impaired subjects. Between September 1999 and April 2000, 203 visually impaired subjects with a headache inventory were surveyed. Those with headache were assessed according to IHS criteria for the presence of migraine. Migraineurs had their symptoms further detailed through an interview and a headache diary. Of the 104 subjects reporting headaches during the last 6 months, 29 had migraine (14.2%). The prevalence of migraine was not influenced by whether the visual impairment was complete or partial. Mean frequency of migraine attacks was 2.7/month. Most subjects (96%) reported severe and/or moderate attacks. Nausea, vomiting, aggravation by activity and phonophobia were reported by 62%, 37.9%, 86.2% and 96.6% of the subjects, respectively. Visual impairment does not seem to influence prevalence of migraine or its clinical features.

Abstract
The tactile analogue scale (TAS) was elaborated to be used in blind subjects or those who can not use the vision during their crises. The objective of this study was to characterize, from TAS, the architecture of migraine attacks in subjects with visual disability. For that, 11 migrainous with visual disturb (MVD) subjects were studied and 22 migrainous subjects with no visual disability as a control group. All patients fulfilled the criteria for migraine and the patients of the group studied showed visual acuteness less than 20/200. To evaluate the results, the patients of the group MVD were subdivide within two groups, according to their visual acuteness: subgroup A subjects with subnormal vision and subgroup B amaurotic ones. In subgroup A measurement 46 attacks with average of the migraine attacks of the 56.50 mm, in the subgroup B 45 attacks with average of the 59.58 mm and in the control group 92 attacks with average of the 49.88 mm. When subgroup B and control group were compared there was a significant statistic difference (p=0.022). Through these outcomes we can observe that the migrainous subjects with no visual afference show a higher pain intensity during the migraine crises comparing to those subjects with no visual handicap. The study suggests that, as in other forms of sensibility, the total visual loss can also interfere in the nociceptive control of the pain during the migraine attacks.

Abstract
Migraine comprises a great many encephalic structures in its pathophysiology with the trigeminal nerve (TN) type being one of the main ones. For the purpose of determining a possible influence of the greater occipital nerve (GON) on migraine behavior, 37 patients who showed this pathology were studied. Using a double blind "cross over" group and submitting those patients to a GON infiltration with bupivacaina 0.5% (BP) and physiological serum 0.9% (PS), the clinical effects were evaluated: subjectively, through a pain analytical visual scale; objectively, by determining the threshold of pain perception (algometry). The comparison between the two groups (BP-PS) and (PS-BP) has shown that the number and duration of the attacks did not show significant statistical differences during the study. The intensity of the attacks was lower in group (BP-PS) only after the second infiltration (p=0.020), in the other moments no differences have been observed between the groups. The conclusion is that the anesthetic blockage with BP on the GON does not change the number of crises and their duration, but it does provokes an intensity reduction after 60 days from the infiltration. The results shown here suggest that GON participates in the cranial nociceptive modulation during crises of migraine without aura.

Abstract
Idiopathic stabbing headache is a quite unknown disorder. Its main features consist of brief stabbing pains, lasting few seconds. In most cases, idiopathic stabbing headache is underdiagnosed. We have followed up migraine patients during a period of 12 months, aiming to determine the prevalence and main features of idiopathic stabbing headache while occurring apart from migraine attacks. Two hundred and thirty-three of the 280 patients initially surveyed were included in the analysis of the results. Ninety-four patients presented idiopathic stabbing headaches (40.4%), being 72 of them females (76.5%). For migraine with idiopathic stabbing headaches, mean age, age of beginning of migraine and years with migraine were 33, 22.5 and 10.6 years, respectively. Mean duration of the idiopathic stabbing headaches was reported to be 1.42 seconds [ 1 second by 68 patients (72.4%), 2 seconds by 17 (18.1%), 3 seconds by 6 (6.3%), 4 seconds by 1 (1.05%) and 5 seconds by 2 (2.15%)]. Pain paroxysms were reported to be unilateral by 86 (91.4%) and bilateral by 8 (8.6%) of the cases. They were reported to be temporal by 56 patients (60%), occipital by 15 (15.6%), frontal by 8 (8.5%), temporo-occipital by 7 (7.4%), parietal by 5 (5.3%), fronto-temporal by 1 (1.06%), cervical by 1 (1.06%) and ocular by 1 patient (1.06%). The study confirms a high prevalence of idiopathic stabbing headaches in migraineurs. Its main clinical features could be well determined during the interval between migraine attacks.

Abstract
Pseudomigraine with pleocytosis is a self-limited and rather benign disorder, characterized by recurrent bouts of migrainous headaches, associated to focal neurological symptoms and to cerebrospinal fluid abnormalities. We have submitted an individual with pseudomigraine to three lumbar punctures. The first and the third lumbar punctures, carried out during symptomatic periods, revealed a cerebrospinal fluid with aseptic lymphomonocytic pleocytosis, and an opening pressure of 400 and 440 mmH2O, respectively. The cerebrospinal fluid pressure measured during an asymptomatic period was normal (190 mmH20). Although the underlying mechanisms of this disorder remain elusive, there is some evidence that suggests an involvement of autoimmune mechanisms leading to a reduction of the cerebral blood flow, similar to that seen in the cortical spreading depression. In this report, we raise the possibility of a contributory role to be played by the elevated cerebrospinal fluid pressure on the pathophysiology of this disorder.

Abstract
Thirty-three migraineurs and 23 healthy controls were submitted to pressure algometry before and after light-induced discomfort was elicited by progressive light stimulation in a monoblind fashion. Pressure algometries were performed on the emergence of the supraorbital, infraorbital, mental and greater occipital nerves, and over the temporal muscles, always throughout the same sequence and from right to left. Measurements were carried out before and immediately after light stimulation and after 10 min of the second algometry. The final result for each site measured at each time-point was the mean of the three measurements. Light stimulation was carried out progressively until light-induced discomfort was reported, to a maximum of 20,000 lux. A heat-blocking glass protected patients' eyes. Migraineurs presented significant and persistent drops in pain perception thresholds after light stimulation, at all sites tested (P = 0.002 to < 0.0001). These drops were not seen in controls, in whom, conversely, a less significant increase was seen on right infraorbital and left temporal muscle sites. Our results indicate that in migraineurs, light may have a relevant role in trigeminal and cervical pain perception thresholds.

Abstract
Algometry of pressure is a technique that measures the physiology of the nociceptive system. Acting directly on the responsive peripheral nociceptors to pressure stimuli, this technique allows the study on nociceptive integrity in normal subjects or having different algic syndromes. Utilizing 29 asymptomatic volunteers, the threshold of the painful perception was studied, measuring them in a direct way over the emergence of the supra-orbital, infra-orbital and mental nerves. The following algometric average were recorded: right mental nerve 46.2 Kg/cm2 and left 48.6 Kg/cm2; right supra-orbital nerve 47.7 Kg/cm2 and left 45.2 Kg/cm2; right infra-orbital nerve 53.9 Kg/cm2 and left 55.4 Kg/cm2. After reviewing the principles of the algometry utilization, we have validated this protocol, showing the average values obtained by measuring the trigeminal system, afterwards comparing them with an inervated region by cervical branches (major occipital nerve) and the temporal muscle.

Abstract
Cranial sensory innervation is supplied mainly by the trigeminal nerves and by the first cervical nerves. Excitatory and inhibitory interactions among those nerve roots may occur in a mechanism called nociceptive convergence, leading to loss of somato-sensory spatial specificity. Three volunteers in an experimental trial had sterile water injected over their greater occipital nerve on one side of the neck. Pain intensity was evaluated 10, 30 and 120 s after the injection. Two of the patients reported intense pain. Trigeminal autonomic features, suggestive of parasympathetic activation, were seen associated with trigeminally distributed pain. These data add to and reinforce previous evidence of convergence of cervical afferents on the trigeminal sensory circuit.

Abstract
Despite the lipomas are the tumors that more commonly occur in the corpus callosum (CC), its incidence in the population is not common. We report on a 5-year old boy, with history of retardation in the psychomotor development and disturbs in the gait, secondary to generalized hypotony. Magnetic resonance imaging showed a curvilinear lipoma of the CC related to its hypertrophy. In the literature patients with CC lipoma usually have agenesis or hypotrophy of the CC, but in the reported case we have seen, by the first time, a hypertrophy of the CC. We made embryologic, genetic, clinical, radiographic and therapeutic considerations about the patients that have CC lipoma comparing to findings in the case we report.

Abstract
The influence of the dopaminergic system on the pathophysiology of migraine has been suggested as a result of recent genetic discoveries. A possible hyper-reactivity of the dopaminergic receptors DRD2 reinforced the evidence regarding this. We describe a 31 years-old male patient affected by a generalized dystonia secondary to perinatal hypoxia. At age 16, the patient started having headache crises that met the criteria for migraine with aura. After three years of treatment for dystonia with tetrabenazine, a clear reduction in the frequency, intensity and duration of the crises was perceived. During two periods longer than two months, the interruption of the treatment with tetrabenazine brought about an aggravation of the migraine crises. We present this case as being the first description in the literature showing the beneficial effects of tetrabenazine, a blocker of dopaminergic receptors, on the behavior of migraine with aura.

Abstract
The transformation of a primary headache into a chronic daily headache (CDH) may or may not be related to the overuse of pain-killers, as their influence on the pathophysiological mechanisms remain inconclusive. We describe three patients (female, aged 65 and 39 years, and male, 46) affected by cervicogenic headache (CH) and CDH linked to the overuse of pain-killers (ergotamine derivatives) that were submitted to the infiltration of the greater occipital nerve (GON). At the end of three days of treatment, a total improvement of the pain symptoms was recorded, which allowed for the withdrawal of the ergotamine derivatives. The CH cannot be ranked with the CDHs, since it presents an organic etiology; however, if the pain is daily and the diagnosis is belated, the indiscriminate and excessive use pain-killers may occur. In the cases described, the overuse of pain-killers did not affect the natural evolution of this headache after treatment with the infiltration of the GON, as all the patients who underwent infiltration showed a total improvement of their painful symptoms, without headache resulting from the withdrawal of pain-killers, nor did they show any pharmacological dependence. This is an evidence that the CH presents and organic etiology, not being influenced in its pathophysiology by the overuse of ergotamine derivatives.

Abstract
Neurofibromatosis type 1 (NF1) can virtually affect any organ, presenting most frequently with "cafe au lait" spots and neurofibromas. Vasculopathy is a known complication of NF1, but cerebrovascular disease is rare. We report the case of a 51-year-old man admitted to the hospital with a history of stroke four months before admission. On physical examination, he presented various "cafe au lait" spots and cutaneous neurofibromas. Neurologic examination demonstrated right-sided facial paralysis, right-sided hemiplegia, and aphasia. Computed tomography scan of head showed hypodense areas in the basal ganglia and centrum semiovale. Radiographs of cranium and cervical spine showed basilar impression. Angiography revealed complete occlusion of both vertebral and left internal carotid arteries, and partial stenosis of the right internal carotid artery. A large network of collateral vessels was present (moyamoya syndrome). It is an uncommon case of occlusive cerebrovascular disease associated with NF1, since most cases described in the literature are in young people, and tend to spare the posterior cerebral circulation. Basilar impression associated with this case may be considered a pure coincidence, but rare cases of basilar impression and NF1 have been described.

Abstract
The case of a 42-year-old woman with prolonged migraine visual aura without headache, whose long-lasting episodes of visual aura were successfully controlled by oral sumatriptan, is reported. Effectiveness of sumatriptan was unequivocal, since, after taking sumatriptan, duration of aura would drop from 1.5 h to approximately 20 min. This case suggests that sumatriptan may cross the blood-brain barrier and block spreading depression.

Abstract
The anatomic distribution of the greater occipital nerve during its path permits a close relationship with muscular structures, tendons, vessels and bones. The rupture of this relationship can origin its irritation and headache. We describe an uncommon association between an osteolytic lesion on occipital bone and greater occipital nerve. The patient, female 50, has been presenting headache for two years on the right occipital region spreading to the hemicranic and ipsilateral supraorbital region. The symptoms started spontaneously or by pressure on the trapezius tendon. The pain lasted about 30 minutes, compressive, mild intensity, with no autonomic symptoms and no improvement after the infiltration in the greater occipital nerve. The total improvement of the symptoms after releasing the nerve has allowed us to associate this lesion to the presence of algic symptoms.

Abstract
We report the case of a 32-year-old woman who complained of dull and compressing occipital pain, with unilateral radiation to the left frontal and supraorbital areas (of the sickening type). The radiological, clinical, neurosurgical and neuropathologic investigation disclosed a medulloblastoma bulging and tickening the tentorium cerebelli. This case shows how mechanical stimuli of the structures innervated by the tentorial nerve can cause pain with characteristics of trigeminal and cervical involvement.

Abstract
Headache is an important diagnostic element in pheochromocytoma and it may characterize a body reaction to pathological hormonal oscillations. We observed the pheochromocytoma instability in 20 patients during arterial hypertension and tried to correlate with headache. We found that isolate hypertension is not the only factor in headache pathogenesis. It is possible that changes in catecholamines, adrenomedullin and other neuropeptides may cause some of these symptoms.

Abstract
A case of acute schistosomiasis with magnetic resonance images (MRI) of the brain suggestive of demyelinating lesions, pyramidal disorder in the lower limbs and normal cerebrospinal fluid is presented. Diagnosis could be established by detection of antibodies on blood and cerebrospinal fluid. Schistosoma mansoni involves the spinal cord more often than the brain. Praziquantel associated to prednisolone was effective in this case. There are few reports of brain involvement with S. mansoni, but its prevalence is probably greater. Due to the paucity of studies, its pathophysiology and therapeutics remain to be better clarified. The immune and MRI aspects are emphasized.

We are not aware of any other report of such association. Until the pathophysiology of the S.U.N.C.T. syndrome becomes completely clarified, the relationship between the preceding ocular trauma and the occurrence of the clinical manifestations remains speculative. Clinical, pathophysiological therapeutic aspects of the S.U.N.C.T. syndrome are reviewed.
