Central nervous system (CNS) - related symptoms occur in haemorrhagic fever with renal syndrome (HFRS). To study the CNS and ophthalmic involvement in nephropathia epidemica (NE), the European type of HFRS, we included 26 patients in a prospective study. Most common CNS-related symptoms were headache (96%), insomnia (83%), vertigo (79%), nausea (79%), and vomiting (71%). Ophthalmic symptoms were reported by 82% of patients; 41% had photophobia and 50% had impaired vision. A transient loss of vision was recorded in one patient, who also had a generalized seizure. Minor white matter lesions were found in about half of the patients investigated with brain magnetic resonance imaging (MRI). Electroencephalography (EEG) showed severe alterations in only one patient, and slight and reversible patterns in another two patients. Neopterin, interleukin-6 and interferon-gamma levels in the cerebrospinal fluid (CSF) were elevated, which may indicate immune activation. However, we found no evidence of intrathecal NE virus replication. We conclude that CNS-related symptoms are common in NE, and transient ophthalmic involvement can be demonstrated in about half of the patients.

We studied 253 children aged <15 years. Phase 1 included 193 children with migraine (1.1 and 1.2) divided into two groups (<10 and > or = 10 years). We studied the relationship between age and migraine type, headache characteristics, and associated symptoms of the International Headache Society (IHS) definition. A higher frequency of migraine with aura, pulsatile quality, and unilateral location was observed in older children. In phase 2 we studied 176 children with headache (excluding migraine with aura), comparing diagnostic criteria, definition items, sensitivity, and specificity. The results showed that item B of the definition was the most frequent cause of exclusion in the 1.7 diagnostic group. Compared with Vahlquist and the IHS, the Prensky criteria were the most sensitive. Sensitivity was >70% for pain of moderate/severe intensity, duration between 2 and 48 h, isolated photophobia, isolated phonophobia, and aggravation with physical activity. Specificity was >70% for nausea, vomiting, phonophobia and photophobia, isolated photophobia, aggravation with physical activity, and isolated phonophobia. Based on three alternative definitions, each modifying one item of the IHS definition, the sensitivity and specificity of these alternative definitions were compared with the "extended" criteria (children with migraine without aura and migrainous disturbance, according to the IHS criteria, grouped together). Exclusion of headache duration increased sensitivity by 10%, compared to restrictive IHS criteria, without decreasing specificity.

This is a study of two children with neuroradiologically diagnosed dolichobasilar anomaly: in both cases, the diagnosis was based on magnetic resonance imaging and magnetic resonance angiography findings. We examined the first child (R., aged 6 years and 8 months) following four episodes of intense pain in the left orbit, lasting between 10 and 30 min and accompanied by photophobia and vomiting. The second child (S., aged 9 years and 2 months), suffering from Marfan's syndrome, was examined following recurrent episodes of intense pain that started above the left orbit, moving to the homolateral orbit after a few minutes. These episodes, which lasted between 20 and 30 min, took place mainly at night and were accompanied by phono-photophobia and vomiting. In both cases, the pain attacks can be interpreted as a result of compression of the root of the trigeminal nerve caused by an arterial malformation.

Migraine is a common illness characterised by severe, often throbbing and/or unilateral headache, which may be accompanied by sensitivity to light or noise. A minority of migraine attacks are preceded by transient visual or sensory disturbances. Migraine is associated with reductions in health-related quality of life both during and between attacks. Despite methodological limitations in cost-of-illness studies, it is clear that the cost of migraine to society is substantial. Indirect costs (primarily workplace productivity losses) make up 75 to 90% of total costs. Direct costs, such as the cost of drug treatment, physician consultation, hospitalisation and emergency room treatment, make up most of the remainder. Sumatriptan is an effective and well tolerated agent in the treatment of migraine. Its main advantage over other agents used in the acute management of migraine appears to be its rapid onset of action. Sumatriptan reduces headache severity within 2 hours of oral administration in 50 to 67% of patients and within 1 hour of subcutaneous administration in 70 to 80% of patients. Headache recurs in approximately 40% of patients who initially respond to oral or subcutaneous sumatriptan; however, a second dose of the drug is effective against the symptoms of recurrence in a majority of patients. Some patients experience relief of non-headache migraine symptoms, including nausea, vomiting, photophobia and phonophobia. Adverse events reported after sumatriptan are generally mild and transient. Data from studies of patients who used their usual therapies and sumatriptan in nonblinded, sequential phases indicate that both workplace and nonworkplace productivity losses were reduced during sumatriptan therapy. A cost-benefit analysis applied to some of these workplace productivity data indicated that, including direct costs and productivity savings, sumatriptan was associated with a net reduction in total cost of migraine. In retrospective cost analyses, sumatriptan was associated with increased prescription costs: the effect of the drug on other direct treatment costs was less clear. A retrospective pharmacoeconomic model suggested that the cost-effectiveness of subcutaneous sumatriptan versus subcutaneous dihydroergotamine depended on which outcome measure was of greatest interest. For measures of rapid relief of migraine, sumatriptan was superior, but the cost of achieving rapid relief was substantial. Sumatriptan improved global quality-of-life scores compared with patients' usual therapy in a randomised crossover trial and appeared to do the same when the drugs were administered in nonblinded, sequential phases in trials which used general and migraine-specific quality-of-life instruments. Thus, sumatriptan is associated with a fast onset of action and improvements in health-related quality of life in patients with migraine. However, the cost of achieving rapid relief of migraine symptoms may be substantial. Compared with patients' usual treatments, sumatriptan appeared to reduce workplace and non-workplace productivity losses. However, few economic data from well controlled prospective comparisons of sumatriptan with other available agents are available to quantify the effect of sumatriptan on the overall cost of migraine.

This review of the literature reveals that migraine is a common, chronic condition featuring episodic attacks which vary in severity and symptomatology. Throbbing, unilateral headache, which is aggravated by activity, is the most prominent feature, although a high proportion of sufferers also experience phonophobia, photophobia and nausea, which may lead to vomiting. Preceding aura is a less common feature of the attack. The frequency and duration of migraine attacks varies widely between individuals, though the median frequency is around 1 attack per month and median duration is roughly 24 h. Migraine attacks can have a profound effect on the day-to-day lives and well-being of the sufferer. In the long term, migraine may cause profound emotional changes and result in coping strategies that interfere with working, social and family life and many normal daily activities. These effects are apparent in quality of life studies on migraine patients. Thus, the impact of migraine on many quality of life parameters is similar to that of other chronic conditions such as osteoarthritis, diabetes and depression. Reduction in the personal burden of migraine can be facilitated by encouraging migraine sufferers to consult their doctor, through accurate diagnosis of migraine headaches and assessment of the disability suffered by the migraineurs, and through improved and well-executed treatment strategies.

This retrospective study sought to examine the benefits of the nonprescription combination of acetaminophen, aspirin, and caffeine (AAC; Excedrin Migraine, Bristol-Myers Squibb Company, New York, New York) for the treatment of menstruation-associated migraine compared with migraine not associated with menses. Data were derived from 3 double-masked, randomized, placebo-controlled, single-dose trials enrolling subjects who met the International Headache Society's diagnostic criteria for migraine with or without aura. Subjects with incapacitating disability (attacks requiring bed rest >50% of the time) and those who usually experienced vomiting > or =20% of the time were excluded. Retrospective analysis of the 1220 subjects included in the efficacy-evaluable data set indicated that 185 women treated menstruation-associated migraine, 781 women treated migraine not associated with menses, and 1 woman provided no information regarding menstrual status. At baseline and at 0.5, 1, 2, 3, 4, and 6 hours postdose, subjects assessed the intensity of headache pain, functional disability, nausea, photophobia, and phonophobia. Pain intensity, nausea, photophobia, and phonophobia were rated on a 4-point scale ranging from 0 = none to 3 = severe; functional disability was rated on a 5-point scale ranging from 0 = none to 4 = incapacitating. For both menstruation-associated migraine and migraine not associated with menses, the proportion of subjects with pain intensity reduced to mild or none (responders) was significantly greater with AAC than with placebo at all postdose time points from 0.5 through 6 hours (P< or =0.05), with no statistically significant difference in treatment effect between menstruation-associated migraine and migraine not associated with menses at any postdose time point. Migraine characteristics such as photophobia, phonophobia, and functional disability were significantly improved in AAC-treated subjects at all time points from 1 through 6 hours (P< or =0.01) in both the menstruating and nonmenstruating groups. Significant relief from nausea was experienced in both menstruation-associated migraine and migraine not associated with menses, but relief appeared earlier in the AAC nonmenstruating subjects (2 hours postdose, P< or =0.01) than in the menstruating subjects (6 hours postdose, P< or =0.05). Beginning at 3 hours postdose, significantly fewer subjects treated with AAC required rescue medication (P< or =0.05) for menstruation-associated migraine (AAC 6%, placebo 15%) and migraine not associated with menses (AAC 7%, placebo 14%). The most commonly used rescue medications in both the menstruating and nonmenstruating groups were nonsteroidal anti-inflammatory drugs, prescription combination analgesics/narcotics, and prescription migraine preparations. AAC was well tolerated in both menstruation-associated migraine and migraine not associated with menses; in general, adverse experiences were similar in both groups. The proportion of subjects who had 1 or more adverse experiences was significantly higher among those receiving AAC than among those receiving placebo (menstruation-associated migraine: AAC 26.4%, placebo 12.6%, P = 0.025; nonmenstruation-associated migraine: AAC 18.6%, placebo 11.4%, P = 0.005). Adverse experiences were similar in type and severity to those previously associated with single doses of acetaminophen, aspirin, or caffeine. Thus the nonprescription combination of AAC was highly effective in treating the pain, disability, and associated symptoms of both menstruation-associated migraine and migraine not associated with menses.

Two-hundred-and-seventy-eight patients with acute migraine attacks with or without aura were treated in 17 centers with 1.8 g lysine acetylsalicylate i.v. (Aspisol; = 1 g acetylsalicylic acid), 6 mg sumatriptan s.c. or placebo using a double-blind, double-dummy, randomized, multicenter parallel group study design. Two-hundred-and-seventy-five of them fulfilled the criteria for efficacy analysis, corresponding to 119 patients treated with lysine acetylsalicylate (L-ASA), 114 with sumatriptan and 42 with placebo injections. Both treatments were highly effective compared to placebo (p < 0.0001) in decreasing headache from severe or moderate to mild or none (verbal rating scale, VRS, placebo = 23.8%). Sumatriptan showed a significantly (p = 0.001) better response (91.2%) compared to L-ASA (response 73.9%). Of the patients in the L-ASA-group, 43.7% were pain-free after 2 h; 76.3% after sumatriptan and 14.3% after placebo. It took patients on average 12.6 (L-ASA), 8.2 (sumatriptan), and 19.4 h (placebo) to be able to work again. There was no significant difference between treatment groups in recurrence of headache in responders within 24 h (18.2% L-ASA, 23.1% sumatriptan, 20% placebo). Accompanying symptoms (nausea, vomiting; photophobia, phonophobia, and visual disturbances) improved with both verum treatments to a similar extent. L-ASA was significantly better tolerated than sumatriptan (adverse events L-ASA 7.6%, sumatriptan 37.8%). In conclusion, subcutaneous sumatriptan and lysine acetylsalicylate i.v. are effective treatments for patients suffering from migraine attacks. Sumatriptan is more effective, but resulted in more adverse events.

Migraine is a paroxysmal disorder characterized by attacks of headache, nausea, vomiting, photophobia, phonophobia, and malaise. This review summarizes new treatment options for therapy of the acute attack. Mild or moderate migraine attacks are treated with antiemetics followed by analgesics such as aspirin, paracetamol, nonsteroidal anti-inflammatory drugs, or antiemetics combined with ergotamine or dihydroergotamine. Sumatriptan, a specific serotonin (5-HT)1B/D agonist is used when attacks do not respond to ergotamine, or when intolerable side effects occur. The new migraine drugs zolmitriptan, naratriptan, rizatriptan, and eletriptan differ slightly in their pharmacological profiles, which translates into minor differences in efficacy, headache recurrence, and side effects. New drugs in migraine prophylaxis include cyclandelate, valproic acid and magnesium.

Migraine is a paroxysmal disorder characterized by attacks of headache, nausea, vomiting, photophobia and phonophobia, and malaise. This review summarizes new treatment options for the therapy of acute attacks. Sumatriptan was the first specific serotonin-1B/D agonist for the treatment of acute migraine attacks. Apart from the oral and subcutaneous formulation, it is also available as nasal spray and suppository. The other new migraine drugs zolmitriptan, naratriptan, rizatriptan and eletriptan differ in their pharmacological profiles, which translates into minor differences in efficacy, headache recurrence and side-effects. Importantly, in clinical practice individual patients may show a preference for one treatment over another. New drugs in migraine treatment include substance-P antagonists, nitric oxide synthetase inhibitors and calcitonin gene-related peptide antagonists.

A 32-year-old woman presented with severe headache, photophobia, fever, nausea, vomiting, and worsening vision. She had also noted several months of amenorrhea. She was febrile to 38.9 degrees C. Laboratory evaluation revealed a markedly elevated erythrocyte sedimentation rate. Lumbar puncture revealed a cerebrospinal fluid lymphocytic pleocytosis and an elevated protein level. Endocrine studies revealed evidence of panhypopituitarism without diabetes insipidus. A magnetic resonance imaging study showed a 2-cm pituitary mass with optic chiasmal compression. The patient had a trans-sphenoidal resection of the mass. Pathology revealed multinucleated giant cells in necrotic debris, but no evidence of pituitary tumor. Studies looking for evidence of systemic granulomatous disease were negative. The patient was considered to have idiopathic giant-cell granulomatous hypophysitis. After surgery, the patient's vision improved and hormone replacement therapy was initiated. This case illustrates that idiopathic giant-cell granulomatous hypophysitis should be considered in the differential diagnosis of a patient presenting with a pituitary mass, hypopituitarism, and meningitis-like symptoms.
