    ABSTRACT: The aims of this study were to identify the generator of the paroxysmal partial discharges in Panayiotopoulos syndrome by means of magnetoencephalography and to determine the significance of these formations in the epileptogenesis of the developing nervous system. We report magnetoencephalographic data for two cases of Panayiotopoulos syndrome showing the rapid generalization of the source of interictal spikes that explains extraoccipital manifestations such as ictal vomiting and consciousness disturbance.

    ABSTRACT: An 11-year-old male was admitted because of frequent vomiting and truncal ataxia which had lasted for over one week. He had clear consciousness but slowly-progressive mild headache and ataxic gait. Cranial CT revealed a 4 cm hematoma in the right cerebellar hemisphere. Angiography showed a 2 x 2 cm nidus of a pial arteriovenous malformation (AVM) in the right hemisphere fed from the right posterior inferior cerebellar artery and draining into the inferior hemispheric vein. We performed a surgical resection of the AVM after decompression therapy to counteract the brain edema. He recovered completely without any neurological deficits. This case suggests that cerebellar hemorrhage caused by AVM should be considered as a possible diagnosis when mild symptoms of headache and ataxia proceed gradually.

    ABSTRACT: We report a 12-year-old boy who had one seizure comprising deviation of the eyes followed by impairment of consciousness for 30 minutes at the age of 6 years. No visual hallucination or ictal vomiting was observed. Interictal electroencephalography showed repetitive spikes and spike-wave discharges over the left occipital lobe. Magnetoencephalography revealed that the estimated dipoles were clustered in the left cuneus on magnetic resonance imaging, which corresponded to the area of peripheral vision and the associated visual cortex but not to the central visual cortex. Magnetoencephalography is advantageous for determining the electrophysiologic mechanism of early-onset benign childhood occipital seizures.

    ABSTRACT: We report on a three-generation family (daughter, mother, and maternal grandmother) with a syndrome of inappropriate secretion of antidiuretic hormone (SIADH)-like condition in the absence of inappropriate ADH secretion. In the three females, a water load test showed severely reduced urinary water excretion, with the ratio of urine volume to the loaded water being 10-33% (normal value: 70.2 +/- 7.8%). Urinary AQP2 excretion was normal, as was the DNA sequence of AVPR2 and AQP2. The results suggest the presence of a new dominantly inherited disorder for tubular water resorption.

    ABSTRACT: Anti-galactocerebroside (anti-GC) antibody has recently been recognized as a possible demyelinating agent. On the 9th day of Mycoplasma pneumoniae (Mp) pneumonia, an 8-year-old boy had a seizure lasting three hours followed by loss of consciousness for 30 hours. Anti-GC antibody titers and myelin basic protein in the CSF were 1:640 and 8.1 ng/dl, respectively. There were no neurological sequelae. It is suggested that the degree of elevation of anti-GC antibody titers in CSF may not correlate well with the severity and neurological prognosis in Mp encephalitis.
