Review Case Reports
[The bilateral long thoracic nerve palsy presenting with "scapula alata", as a result of weight training. A case report].
A 28-year-old male barber with no similar disease in his family admitted to our hospital because of difficulty of raising his arms in March 2003. When he was 18 years old, he broke his left clavicle. He started weight training from January 2003, then he gradually felt difficulty to raise his arms. ⋯ Thus the diagnosis of bilateral long thoracic nerve palsy was made. Bilateral scapular winging (scapula alata) is commonly caused by systemic disease, especially muscular dystrophy or spinal muscular atrophy. Bilateral long thoracic nerve palsy by weight training should be known as one of the cause for the "scapula alata".

Case Reports
[Traumatic extracranial vertebral artery dissection treated with coil embolization--a case report].
We reported a 37-year-old man who developed vertigo, dysarthria and left hemiparesis following neck pain. Magnetic resonance imaging (MRI) demonstrated infarct in the right superior cerebellar artery (SCA) territory. Duplex color-flow imaging detected dissection (double lumen) in the right vertebral artery (VA) at the level of the C4-C6 vertebra (V2 segment). ⋯ Despite administration of anti-thrombotic agents, he recurrently suffered from transient ischemic attacks. Serial duplex color-flow imaging echography revealed that the dissection of the right VA gradually became more stenotic and extended to the distal site. Coil-embolization of the right VA by endovascular therapy was performed, and thereafter the dissecting lesion of the right VA was completely occluded and ischemic attacks disappeared.

Case Reports
[A case of multiple sclerosis with bilateral useless hand syndrome as a main clinical feature].
A 41-year-old, right-handed man was admitted to our hospital on September 12, 2002, due to progressive clumsiness in both hands. The patient had been diagnosed as having multiple sclerosis three years prior to admission. He noticed difficulty in manipulating objects three months before admission. ⋯ Clumsiness of fine finger movements with astereognosis in our patient is similar to numb clumsy hands or limb-kinetic apraxia due to cervical spondylosis or postcentral gyrus lesion, respectively. This indicates an important role of the high cervical posterior cord in conveying a kinesthetic sense necessary to guide fine finger movements. It should be kept in mind that high cervical lesions in multiple sclerosis causes clumsy hands mimicking limb-kinetic apraxia.

Case Reports
[A case of early stage CADASIL showing only dizziness and vertigo with a novel mutation of Notch 3 gene].
We report a 39-year-old woman who presented with only dizziness and vertigo for 2 months. Neurological examination revealed no abnormalities except for hypereflexia on the left side extremities. Neurootological examination revealed no abnormalities. ⋯ Mutational analysis of Notch3 gene disclosed a novel missense mutation substituting arginine for cysteine at codon 206 (C206R) in exon 4 of the Notch3 gene, confirming the diagnosis of CADASIL. Interestingly, similar dizziness and vertigo were present not only in the patient, but also in the other two sisters who had the same gene mutation as the patient. This report supports the idea that the external capsule lesion is one of the signs suggestive of CADASIL as a diagnosis.

Cluster headaches are characterized by strictly unilateral paroxysmal attacks of severe pain with associated autonomic sign and symptom. Prevalence is 5 times higher in men than in women in our cases. About 10-15% of patients have chronic symptoms without remissions, but we estimated less frequent in Japanese (6.6% in our series). ⋯ Treatment of cluster headache includes both acute therapy aimed at aborting individual attacks and prophylactic therapy aimed at preventing recurrent attacks during the cluster period. There are many choices using for both therapies. Based on our clinical experience, we recommended the combination of nasal sumatriptan for acute attacks and verapamil 240 mg/day for prophylaxis.
