Electroconvulsive therapy (ECT) has been frequently considered relatively contraindicated in patients with space-occupying lesions in the brain. After the 7 cases available in the literature, we describe the safe use of ECT in a depressive patient with arachnoid cyst. We provide a comprehensive review on this clinical association, and we conclude that even if the few data available are reassuring, careful neurological evaluation before the ECT treatment is indicated.

L’électroconvulsivothérapie (anciennement dénommée sismothérapie, électronarcose ou électrochoc) est une technique thérapeutique utilisée dans certaines affections psychiatriques. Elle consiste en la réalisation d’une crise convulsive généralisée induite par le passage d’un courant électrique transcrânien. S’il est vrai que cette méthode continue de stigmatiser l’imaginaire collectif en suscitant effroi et méfiance (modèle de barbarie thérapeutique pour certains, traitement obsolète pour d’autres), elle se révèle, au contraire, être un traitement souvent très efficace, dans certains cas irremplaçable, et dans l’ensemble très bien toléré. Ainsi, ces dernières années ont vu un regain d’intérêt pour l’ECT. Elle constitue, aujourd’hui, la plus ancienne des somathérapies psychiatriques toujours en vigueur. [less ▲]

A new composite material prepared by mixing polycarbonate with carbon black has been tested as new kind of cathode, This material has been compared with a conducting polymer precipitated onto polycarbonate, both in aqueous and organic solutions. We report some examples of electrodeposition of magnetic alloys (Lanthanides/Transition metals) in Formamide, In this medium, the use of thin polypyrrole films cathodes had remained impossible, The preparation of amorphous and magnetic alloys onto PC/carbon black is evidenced by RES.

Adherent thin polymer films have been prepared by sequential electrodeposition of ethyl acrylate (EA) and acrylonitrile (AN) onto nickel. Their composition has been studied by IR spectroscopy and time of flight-secondary ion mass spectrometry. Morphology and thickness have been analyzed by atomic force microscopy and ellipsometry, respectively, and compared to single component films of PEA and PAN. No microphase separation was detected in the mixed PEA/PAN films. These show a granular morphology comparable to that of PAN films. The grains contain the two constitutive polymers, as confirmed by the selective thermal degradation of PEA. [less ▲]

The use of information-based measures to assess changes in conscious state is an increasingly popular topic. Though recent results have seemed to justify the merits of such methods, little has been done to investigate the applicability of such measures to children. For our work, we used the approximate entropy (ApEn), a measure previously shown to correlate with changes in conscious state when applied to the electroencephalogram (EEG), and sought to confirm whether previously reported trends in adult ApEn values across wake and sleep were present in children. Besides validating the prior findings that ApEn decreases from wake to sleep (including wake, rapid eye movement (REM) sleep, and non-REM sleep) in adults, we found that previously reported ApEn decreases across vigilance states in adults were also present in children (ApEn trends for both age groups: wake > REM sleep > non-REM sleep). When comparing ApEn values between age groups, adults had significantly larger ApEn values than children during wakefulness. After the application of an 8 Hz high-pass filter to the EEG signal, ApEn values were recalculated. The number of electrodes with significant vigilance state effects dropped from all 109 electrodes with the original 1 Hz filter to 1 electrode with the 8 Hz filter. The number of electrodes with significant age effects dropped from 10 to 4. Our results support the notion that ApEn can reliably distinguish between vigilance states, with low-frequency sleep-related oscillations implicated as the driver of changes between vigilance states. We suggest that the observed differences between adult and child ApEn values during wake may reflect differences in connectivity between age groups, a factor which may be important in the use of EEG to measure consciousness.

BACKGROUND: Electroencephalography (EEG) is best suited for long-term monitoring of brain functions in patients with disorders of consciousness (DOC). Mathematical tools are needed to facilitate efficient interpretation of long-duration sleep-wake EEG recordings. METHODS: Starting with matching pursuit (MP) decomposition, we automatically detect and parametrize sleep spindles, slow wave activity, K-complexes and alpha, beta and theta waves present in EEG recordings, and automatically construct profiles of their time evolution, relevant to the assessment of residual brain function in patients with DOC. RESULTS: Above proposed EEG profiles were computed for 32 patients diagnosed as minimally conscious state (MCS, 20 patients), vegetative state/unresponsive wakefulness syndrome (VS/UWS, 11 patients) and Locked-in Syndrome (LiS, 1 patient). Their interpretation revealed significant correlations between patients' behavioral diagnosis and: (a) occurrence of sleep EEG patterns including sleep spindles, slow wave activity and light/deep sleep cycles, (b) appearance and variability across time of alpha, beta, and theta rhythms. Discrimination between MCS and VS/UWS based upon prominent features of these profiles classified correctly 87 % of cases. CONCLUSIONS: Proposed EEG profiles offer user-independent, repeatable, comprehensive and continuous representation of relevant EEG characteristics, intended as an aid in differentiation between VS/UWS and MCS states and diagnostic prognosis. To enable further development of this methodology into clinically usable tests, we share user-friendly software for MP decomposition of EEG (http://braintech.pl/svarog) and scripts used for creation of the presented profiles (attached to this article).

Among the high research activity in the area of surface modification, electrografting is a very powerful and effective technique. When conducted under appropriate conditions of solvent and cathodic potential, the electropolymerization of (meth)acrylic monomers results in the chemisorption of the polymer on the conducting surface. This one-step electrografting technique is very easily implemented, can be applied to a wide range of (semi)-conducting surfaces by keeping the same chemistry and requires commonly used, readily available (meth)acrylate monomers. The wide variety of acrylic monomers suitable for this process makes available a broad range of surface properties including bactericidal, superhydrophobic and proteins repellent coatings. Electrografted smart coatings able to respond to external stimuli are also of interest particularly for sensors and actuators. [less ▲]
