Monotherapy Trials with Gabapentin for Partial Epilepsy
The efficacy and safety of gabapentin as monotherapy for treatment of partial onset seizures were evaluated in three large multicenter, double-blind, parallel-group, dose-controlled trials. In the first trial, 275 outpatients with refractory partial epilepsy maintained on stable doses of one or two antiepileptic drugs (AEDs) were switched to gabapentin (GBP) monotherapy at 600 mg, 1200 mg, or 2400 mg daily. Patients were required to exit the 26-week double-blind phase of the study if they experienced worsening of seizure frequency. With respect to time to exit, there was no statistically significant difference among the three groups; only 3% of patients withdrew from the trial because of adverse events. In the second study, 82 hospitalized patients with medically refractory epilepsy were tapered off baseline AEDs and randomly assigned to GBP monotherapy at 300 mg/day or 3600 mg/day. Patients remained in the trial for a maximum of 8 days but had to exit the trial if they experienced one or more exit events. Time to exit was significantly longer in patients in the 3600-mg group (151 h) compared with those in the 300-mg group (85 h) ( p = 0.0001). None of the patients withdrew from the trial because of side effects. In the third study, 292 patients with newly diagnosed partial seizures were randomized to GBP 300, 900, or 1800 mg/day or to carbamazepine (CBZ) 600 mg/day. Patients remained in the trial for up to 6 months or until they experienced an exit event. Mean time to exit was significantly longer for patients who received GBP 900 mg/day ( p = 0.02) or 1800 mg/day ( p = 0.04) compared with those who received 300 mg/day. The completion rate for the CBZ group (37%) was similar to that of the GBP 900-mg (39%) and 1800-mg (38%) groups. Patients receiving CBZ had a higher withdrawal rate because of adverse events compared with the GBP 900-mg and 1800-mg groups. The results of these trials provide good evidence of the efficacy and safety of GBP as monotherapy for the treatment of partial-onset seizures.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/65608/1/j.1528-1157.1999.tb00927.x.pd
Relaying Memory through a Generated Environment
Abstract:
Khiam Detention Centre (KDC), a detention camp established by Israel in South Lebanon in 1985, is currently under heavy political interference that aims to manipulate and monopolise the writing of its burdened history. The preservation of memory of events that took place in this prison needs to be urgently addressed in the face of multiple attempts of its erasure and biased revisions. This study surveys three types of media sources that contain the memory of KDC: 1) interviews conducted with former prisoners; 2) the data-archives of a radio programme called Nahnu Bikhayr Taminuna Ankom(We are alive, tell us if you are) and 3) the built environment mapped with a sonic device. The extracted memories are then transcluded to a generated environment that virtually relays the mnemonic site of KDC. This project was done out of an urgent need to preserve KDCâs media imprints that are prone to erasure and modification. KDC is situated on the border of South Lebanon, a territory whose land and electromagnetic field have been occupied by state and non-state political actors. Since the claims of technological sovereignty inside the territory are tenuous and rife with the risk of political manipulation, I chose the space of the internet as provisionally more inclusive environment to host the virtual environment of KDC. Through three media sources, the generated environment allows users to experiment with the limitations and imposition of sound, allowing the critical recreation of the KDC site.

POWER OF CANTILEVER DESIGN IN THE CONTEMPORARY ARCHITECTURE
Cantilever is a structural form that extends horizontally and is supported by one end and free on the other while the load is distributed equally, initiated by the use of bridges and balconies in the buildings. The power of Cantilevers with its different designs is spreading throughout the world via various perspectives since it increases the ability of design creativity and gives proper solutions. However, from that point forward, a research gap that has been found missing relating the structural challenges and how it affects the design and the decisions taken by the clients/ owners paying budgets on such type of structural additions that may not achieve the 100% building safety. Lack of knowing the proper building technologies may lead to reduce limits of innovation, that resulted in building repetitive traditional prototype without remarkable decisions. This paper therefore aims to detect the new building technologies that enable architects to design a cantilever in their projects, helping the design and the load carrying problems and highlight the exceptional designs that challenges the attractive force and establish a flying structure. In order to achieve the mentioned aim, the paper will start presenting a literature review based on a desk research theories and methods of construction were used to clearly explains our topic âthe power of cantilevers in contemporary arch.â Supported with diverse analysis of Frank Lloyd Wright, Zaha Hadid, and Knight Architects
Longitudinal EEG Studies in a Kindred with Lafora Disease
We reviewed 18 EEG studies in four members of a family with the Lafora form of progressive myoclonic epilepsy. Each patient was the product of a consan-guinous marriage and presented as a teenager with progressive seizures, myoclonus, dementia, and ataxia, and had biopsy proven disease. The EEG early in Lafora disease has spike-wave activity resembling that seen in a primary generalized epilepsy; the background slowing is more typical of a secondary generalized epilepsy. With disease progression, there is increased epileptiform activity, and a striking change in the spike-wave complexes, with a marked increase in frequency up to 6â12 Hz, and many more short duration poly spike components. Unlike some other forms of secondarily generalized epilepsy, the EEG in Lafora disease is distinguished by an increased frequency of the spike-wave complexes with disease progression.

RESUMEN Se revisan 18 estudios de EEG en 4 miembros de una familia con la forma de Lafora de una epilepsĂa mioclĂnica progresiva. Cada paciente fue producto de un matrimonio consanguĂneo y en su adolescencia presentaron ataques progresivos, mioclonĂas, demencia y ataxia, y se les practiceĂ una biopsia que confirmĂ la enfermedad. Los EEGs practicados precozmente en la enfer-medad de Lafora tienen una actividad de punta-onda que semeja la que se observa en epilepsĂa generalizada primaria y la lentifi-caciĂn de la actividad de fondo es mĂs tĂpica de epilepsĂa generalizada sencundaria. A medida que la enfermedad progresa se observĂ un incremento de la actividad epileptiforme y un cambio sorprendente en los complejos punta-onda con marcado incremento de la frecuencia hasta 6â12 Hz. y muchos mĂs compo-nentes de polipuntas de breve duraciĂn. Contrariamente a otras formas de epilepsĂa generalizada secundaria el EEG en la enfermedad de Lafora se caracteriza por un incremento de la frecuencia de los complejos punta-onda a medida que la enfermedad progresa. ZUSAMMENFASSUNG Wir beurteilten 18 EEG-Untersuchungen bei 4 Mitgliedern einer Familie mit der Lafora-Form der progressiven Myoklonus-Epilepsie. Jeder Patient entstammte einer konsanguinen Ehe und wurde als Teenager mit progressiven AnfĂllen, Myoklonus, De-menz und Ataxie auffĂllig; die Diagnose wurde durch Biopsie bestĂtigt. Das EEG im frĂhen Verlauf einer Lafora-Erkrankung zeigt Spike Wave AktivitĂt, die der bei primĂr generalisierter Epilepsie Ăhnelt, wĂhrend die HintergrundaktivitĂt mehr fĂr eine sekundĂr generaliserte Epilepsie typisch ist. Mit fortschreitender Erkrankung tritt vermehrt epileptische AktivitĂt und ein deutli-cher Wechsel der Spike Wave Komplexe mit starkem Ansteigen der Frequenz auf 6â12 Hz und vermehrten kurzdauernden Polyspike-Komponenten auf. Im Gegensatz zu anderen Formen sekundĂr generalisierter Epilepsien zeigt das EEG bei der Lafora-Erkrankung mit Erkrankungsfortgang eine zunehmende Frequenz der Spike Wave Komplexe.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/65436/1/j.1528-1157.1991.tb05548.x.pd

Generalized Spike-Waves, Multiple Loci, and Clinical Course in Children with EEG Features of Benign Epilepsy of Childhood with Centrotemporal Spikes
In 41 patients with EEG features of benign epilepsy of childhood with centrotemporal spikes (BECCT), we noted associated generalized spike-wave discharges (GSWD) in 14.6% and multiple independent sharp wave foci in 9.8%. The presence or absence of these EEG features was not predictive of the clinical course. The high incidence of GSWD in children with BECCT suggests a possible relation in the expression of these two EEG traits.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66418/1/j.1528-1157.1992.tb01764.x.pd
Unilateral 14 and 6 Hz positive bursts
We describe the unilateral occurrence of 14 and 6 Hz positive bursts in successive EEGs in a 25-year-old woman following surgical resection of a left parietal arteriovenous malformation which had caused a left parieto-temporal intracerebral hematoma.This is only the second reported case of unilateral 14 and 6 Hz positive bursts. This could represent either a normal pattern seen unilaterally because of a skull defect or be a manifestation of neuronal damage.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/30132/1/0000509.pd
Variance of interburst intervals in burst suppression
Each EEG performed over a 3 year period at the University of Michigan with a diagnosis of generalized burst-suppression (BS) was reviewed. Ten EEGs from 10 patients with hypoxic-ischemic encephalopathy (HIE-BS) and 21 records from 8 patients with pentobarbital induced burst-suppression for treatment of status epilepticus (SE-BS) were reviewed. For each EEG, the mean duration of 40 interburst intervals (IBIs) as well as their coefficient of variability were calculated. We found that in the SE-BS group the coefficient of variability of IBI duration was highly correlated with the logarithm of mean IBI duration while in the HIE-BS group, there was no significant correlation between these 2 variables. This suggests that the underlying mechanism causing BS is different in the 2 groups and might be related to a uniform and progressive affection of similar brain structures in the SE-BS group and a more patchy and variable pathology in the HIE-BS group.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29010/1/0000039.pd
Novel mental retardationâepilepsy syndrome linked to Xp21.1âp11.4
We evaluated a kindred with X-linked mental retardation and epilepsy. Seven affected males with mild to moderate mental retardation developed seizures (primarily generalized, tonicâclonic, and atonic) that began on average at 6.8 months of age (range, 4 to 14 months). These patients did not have a history of infantile spasms. There were no dysmorphic features. Other than mental retardation, the neurological examination was unremarkable, with exception of 2 affected subjects who had mild generalized rigidity and ataxia. We identified tight linkage to a group of markers on Xp21.1âp11.4. A maximum two-point LOD score of +3.83 at Ξ = 0 was obtained for markers DXS8090, DXS1069, DXS8102, and DXS8085. This locus spans 7.7cM between DXS1049 and DXS8054 and does not overlap the locus for X-linked West syndrome. The tetraspanin gene, implicated in nonspecific mental retardation, is mapped to this region. We sequenced the tetraspanin coding sequence in subjects with X-linked mental retardation and epilepsy and did not identify disease-specific mutations. The syndrome we describe, designated X-linked mental retardation and epilepsy, is clinically and genetically distinct from X-linked West syndrome and other X-linked mental retardationâepilepsy syndromes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/34887/1/10051_ftp.pd
