1/437. Serial electroencephalographic findings in patients with MELAS.

    To clarify the electroencephalographic characteristics of mitochondrial myopathy, encephalopathy, lactic acidosis, and strokelike episodes (MELAS), the medical records and electroencephalograms of six patients with MELAS and two of their relatives with MELA (mitochondrial myopathy, encephalopathy, and lactic acidosis, without strokelike episodes) were retrospectively reviewed. All have a point mutation in the mitochondrial dna at nucleotide position 3243. The electroencephalograms (n = 79) were divided into four groups according to the time relation to the strokelike episode: (1) before the first strokelike episode, (2) within 5 days after the strokelike episode (acute stage), (3) between 6 days and 1 month after the strokelike episode (subacute stage), and (4) more than 1 month after the strokelike episode (chronic stage). In the acute stage, 10 of the 11 electroencephalograms (9 strokelike episodes in four patients) revealed focal high-voltage delta waves with polyspikes (FHDPS), which were recognized as ictal electroencephalogram. Ictal events during FHDPS included focal clonic or myoclonic seizure and migrainous headache. In the subacute and chronic stages, focal spikes or sharp waves and 14- and 6-Hz positive bursts were frequently recorded. The authors' results suggest that FHDPSs present a reliable and accurate indicator of a strokelike episode in patients with MELAS.

2/437. Limb-threatening lower extremity ischemia successfully treated with intra-arterial infusion--case reports.

    The authors present two patients with acute arterial vasospasm of the lower extremities causing marked ischemia. One patient had a history of Raynaud's disease, the second had been taking Cafergot for migraine headaches. Both patients's were given a test dose of intra-arterial tolazoline (50 mg). The patient with Raynaud's disease demonstrated marked improvement diffusely and was successfully treated with overnight infusion of papaverine. The second patient, taking Cafergot, demonstrated no angiographic response to tolazoline. It was speculated that the arteries of this patient were thrombosed. The patient was successfully treated with urokinase and remained free of pain at the 15-month follow-up.

3/437. Lamotrigine in the prophylactic treatment of migraine aura--a pilot study.

    The aim of this study was to evaluate the efficacy of lamotrigine, a glutamate antagonist blocking voltage-sensitive sodium channels, in the prophylaxis of migraine aura symptoms. Glutamate is one of the main neurotransmitters involved in the development of cortical spreading depression. The study was conducted as an open longitudinal trial over 7 months, with a treatment phase of 4 months and a post-treatment period of 3 months. Thirteen patients suffering from migraine with aura and 2 patients with aura but without migraine were enrolled and treated with lamotrigine. The dose was gradually increased in steps of 25 mg up to 100 mg per day, depending on the patient's aura symptoms. Aura symptoms were reduced from baseline (an average of 1.3 aura episodes per month) to month 4 (0.1, p < 0.001). High statistical significance was also observed with regard to aura duration (23 min at baseline vs 4 min at 4 months, p < 0.001). In all 15 cases, increases in aura frequency (on average sevenfold, p < 0.001) and aura duration (minutes; on average more than threefold, p < 0.001) were evident following cessation of treatment. A number of mild to moderate adverse events without any medical consequences occurred. The study outcome suggests that lamotrigine is effective in preventing migraine aura symptoms and in influencing migraine headache frequency.

4/437. Medicolegal issues: headache.

    This article addresses headache-related topics in which medicolegal issues have occurred or in which they are likely to occur. Where possible, an actual case has been presented. Most sections of this article are divided into three parts: principle of care, case history, and discussion and recommendations. When appropriate, American Academy of neurology guidelines have been noted.

5/437. ophthalmoplegic migraine and periodic migrainous neuralgia, migraine variants with ocular manifestations.

    The spectrum of migraine has been outlined with particular attention to two entities: ophthalmoplegic migraine and Periodic Migrainous neuralgia. Although quite different in many respects from classical migraine, the relationship of a periodic localized vascular phenomenon giving rise to headache and transient neurologic signs, classify PMN and OPGM as migraine variants. Supportive of this concept, the literature has been reviewed in both entities, and some observations are made on the validity of earlier reports. It is the author's opinion that Raeder's syndrome should be reserved for patients with a lesion localizing in the paratrigeminal area. This does not exclude migraine as an etiologic agent but also recognizes tumors, infections and fractures as being more common.

6/437. Prolonged migraine aura without headache arrested by sumatriptan. A case report with further considerations.

    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.

7/437. ergotamine-induced intermittent claudication.

    We report about a female patient with intermittent claudication caused by ergotamine. She used ergotamine as a treatment for migraine headaches for more than 4 years. The claudication began 7 month before admission. Colour Doppler sonography and angiography showed severe stenosis of the left external iliac and superficial femoral artery. The patient was treated with phenprocoumon for one year after withdrawal of ergotamine. After that the superficial femoral stenosis disappeared completely, but the external iliac stenosis was still present and was consequently successfully treated by atherectomy. The histology showed a fibrosis of the intima and a hypertrophy of the media.

8/437. migraine with aura-like headache associated with moyamoya disease.

    A 49-year-old woman was admitted to our hospital because of severe headache. She had a 10-month history of migraine with aura-like headache that occurred every 7 to 10 days and was preceded by photopsia. Brain CT showed cerebral infarction of the left occipital lobe. Bilateral carotid angiograms showed vascular occlusions in the supraclinoid portion of the bilateral internal carotid arteries with telangiectatic vessels acting as collateral channels to the occluded distal carotid arteries, which were consistent with the diagnosis of moyamoya disease. headache resolved gradually and has never developed again after the infarct of the left occipital lobe. Pathophysiological mechanisms of migraine-like headache were discussed. We conclude that borderline perfusion of occipital lobe cortex could be a trigger for the development of migraine with aura-like headache in susceptible patients. In the case of atypical attack of migraine detailed investigation should be done to detect underlying vascular diseases such as moyamoya disease.

9/437. abdominal pain in children.

    Chronic vague abdominal pain is an extremely common complaint in children over 5 years, with a peak incidence in the 8 to 10 year group. In over 90 per cent of the cases no serious underlying organic disease will be discovered. Most disease states can be ruled out by a careful history, a meticulous physical examination, and a few simple laboratory tests such as urinalysis, sedimentation rate, hemoglobin, white blood count determination, and examination of a blood smear. If organic disease is present there are often clues in the history and the examination. The kidney is often the culprit--an intravenous pyelogram should be done if disease is suspected. barium enema is the next most valuable test. Duodenal ulcers and abdominal epilepsy are rare and are over-diagnosed. If no organic cause is found, the parents must be convinced that the pain is real, and that "functional" does not mean "imaginary." This is best explained by comparing with "headache"--the headache resulting from stress and tension hurts every bit as much as the headache caused by a brain tumor or other intracranial pathology. Having convinced the patient and his parents that no serious disease exists, no further investigation should be carried out unless new signs or symptoms appear. The child must be returned to full activity immediately.

10/437. oculomotor nerve schwannoma associated with ophthalmoplegic migraine.

    PURPOSE: To describe a patient with an oculomotor nerve schwannoma who had symptoms of ophthalmoplegic migraine. methods: Case report. RESULTS: A 23-year-old woman had a history of recurrent headache accompanied by transient right oculomotor palsy since age 7 years. ophthalmoplegic migraine was diagnosed. She was subsequently found to have a structural lesion of her right oculomotor nerve on magnetic resonance imaging. The magnetic resonance image characteristics were consistent with schwannoma originating from the oculomotor nerve. CONCLUSIONS: This case illustrates that an intrinsic lesion of the oculomotor nerve (schwannoma) may be associated with a painful relapsing-remitting oculomotor palsy mimicking the clinical syndrome of ophthalmoplegic migraine.
