Efficacy and safety of perampanel monotherapy in patients with focal-onset seizures with newly diagnosed epilepsy or recurrence of epilepsy after a period of remission: The open-label Study 342 (FREEDOM Study).

Objective: Our study assessed perampanel monotherapy in patients (aged ≥12 years) with focal-onset seizures (FOS) with or without focal to bilateral tonic-clonic seizures (FBTCS) in Japan and South Korea.

Methods: Study 342 (NCT03201900; FREEDOM) is a single-arm, open-label, Phase III study. Patients initially received perampanel in a 32-week 4-mg/d Treatment Phase (6-week Titration; 26-week Maintenance Periods).

[Cases of three patients undergoing chemotherapy for gastric cancer who developed Trousseau's syndrome].

Trousseau's syndrome involves unexplained thrombotic events along with malignancy. We report the cases of 3 patients undergoing chemotherapy for gastric cancer in whom Trousseau's syndrome occurred. Case 1 involved a 43-year-old woman undergoing S-1/cisplatin( CDDP) combination therapy as first-line chemotherapy for type 4 remnant gastric cancer( cT4bN2M1P1/stage IV) who experienced left hemiplegia.

Determination of language dominance with synthetic aperture magnetometry: comparison with the Wada test.

Cerebral dominance for language function was investigated with synthetic aperture magnetometry (SAM). The results were compared with those of the Wada test. SAM is a spatial filtering technique that enables demonstration of the spatiotemporal distribution of oscillatory changes (synchronization and desynchronization) in magnetoencephalography (MEG) signals elicited by specific brain activation.

[Application of synthetic aperture magnetometry for epilepsy surgery].

Recently developed synthetic aperture magnetometry (SAM) is a new MEG signal analysis introducing a high performance spatial filtering technique. SAM is not an inverse solution like dipole analysis, but rather an adaptive beamformer for estimating source activity at each selected voxel inside of the brain. SAM can estimate source changes as a function of time, or power changes subjected to statistical analysis from the non-averaged raw MEG data.

Neuromagnetic gamma-band activity in the primary and secondary somatosensory areas.

To evaluate the gamma-band activity related to somatosensory processing, we recorded neuromagnetic signals from seven healthy subjects. The source power changes evoked by electrical stimulation of the median nerve were estimated with synthetic aperture magnetometry (SAM). Source power in the low gamma band (40 Hz) decreased in the contralateral primary somatosensory cortex (SI) for a few hundred milliseconds (i.

Frequency-dependent spatial distribution of human somatosensory evoked neuromagnetic fields.

Using synthetic aperture magnetometry (SAM), we examined the spatial distribution of frequency changes in magnetoencephalography signal rhythms on individual magnetic resonance images following somatosensory stimulation. SAM is a novel statistical spatial filtering method that uses an adaptive beamformer. Electrical stimulation of the right median nerve demonstrated high-frequency event-related synchronization (ERS) in the 50-200-Hz range, consistently localized in the contralateral primary sensorimotor area in all subjects (n=7).
