Tolerability of clobazam as add-on therapy in patients aged 50 years and older with drug-resistant epilepsy.

Objective: To evaluate the tolerability of clobazam in patients with drug-resistant epilepsy aged 50 years and older.

Methods: We performed a single center, retrospective chart review of patients at least 50 years of age with drug resistant epilepsy of any type who started clobazam as an add on therapy. Retention rate, safety, and tolerability at 6 and 12 months and last follow-up, and the discontinuation rate due to side effects were analyzed.

A quantitative method for evaluating cortical responses to electrical stimulation.

Background: Electrical stimulation of the cortex using subdurally implanted electrodes can causally reveal structural connectivity by eliciting cortico-cortical evoked potentials (CCEPs). While many studies have demonstrated the potential value of CCEPs, the methods to evaluate them were often relatively subjective, did not consider potential artifacts, and did not lend themselves to systematic scientific investigations.

New Method: We developed an automated and quantitative method called SIGNI (Stimulation-Induced Gamma-based Network Identification) to evaluate cortical population-level responses to electrical stimulation that minimizes the impact of electrical artifacts.

A case of paraneoplastic neuromyelitis optica associated with small cell lung carcinoma.

Neuromyelitis optic spectrum disorders are demyelinating conditions that are typically idiopathic, though various case reports have demonstrated an association with malignancy. We present the case of a 64year old woman with NMOSD in the setting of small cell lung cancer. She had longitudinally extensive transverse myelitis and left eye optic neuritis; aquaporin-4 antibodies were elevated.

Barriers to the use of intravenous tissue plasminogen activator for in-hospital strokes.

Background: Patients who have ischemic strokes (ISs) while hospitalized for other conditions may be less likely to receive intravenous tissue plasminogen activator (IV tPA) when compared to patients who have strokes in the community. This study explored possible barriers to IV tPA use in these patients.

Methods: Stroke diagnosis was confirmed by chart review for all adult patients admitted to Bellevue Hospital between January 1, 2004 and December 31, 2008 who were discharged with a primary or secondary International Classification of Diseases, 9th edition code for transient ischemic attack, intracerebral hemorrhage, or IS.
