  • Tracking generalized tonic-clonic seizures with a wrist accelerometer linked to an online database SEIZURE-EUROPEAN JOURNAL OF EPILEPSY Velez, M., Fisher, R. S., Bartlett, V., Le, S. 2016; 39: 13-18

    Abstract

    Clinical management of epilepsy and current epilepsy therapy trials rely on paper or electronic diaries often with inaccurate self-reported seizure frequency as the primary outcome. This is the first study addressing the feasibility of detecting and recording generalized tonic-clonic seizures (GTCS) through a biosensor linked to an online seizure database.A prospective trial was conducted with video-EEG (vEEG) in an epilepsy monitoring unit. Patients wore a wristwatch accelerometer that detected shaking and transmitted events via Bluetooth® to a bedside electronic tablet and then via Wi-Fi to an online portal. The watch recorded the date, time, audio, duration, frequency and amplitude of events. Events logged by the watch and recorded in a bedside paper diary were measured against vEEG, the "gold standard."Thirty patients were enrolled and 62 seizures were recorded on vEEG: 31 convulsive and 31 non-convulsive. Twelve patients had a total of 31 convulsive seizures, and of those, 10 patients had 13 GTCS. The watch captured 12/13 (92.3%) GTCS. Watch audio recordings were consistent with seizures in 11/12 (91.6%). Data were successfully transferred to the bedside tablet in 11/12 (91.6%), and to the online database in 10/12 (83.3%) GTCS. The watch recorded 81 false positives, of which 42/81 (51%) were cancelled by the patients. Patients and caregivers verbally reported 15/62 seizures (24.2% sensitivity) but no seizures were recorded on paper logs.Automatic detection and recording of GTCS to an online database is feasible and may be more informative than seizure logging in a paper diary.

  • Detection of inferolateral trunk syndrome by neuromonitoring during catheter angiography with provocative testing. Journal of neurointerventional surgery Le, S., Dodd, R., López, J., Nguyen, V., Cho, S. C., Lee, L. 2013; 5 (2)

    Abstract

    It is not uncommon that endovascular balloon test occlusion (BTO) is performed to assess collateral blood flow and risk of injury of permanent occlusion of the internal carotid artery (ICA). This case is the first reported of detection and reversal of the inferolateral trunk (ILT) syndrome in an awake patient during provocative BTO; prompt recognition of the syndrome effectively prevented permanent neurologic deficits.The case of a 42-year-old woman is reported who had a left sphenoid wing meningioma with extension into the cavernous sinus and who underwent awake catheter angiography with provocative BTO of the ICA. Serial examinations by intraoperative monitoring neurologists and neurointerventionalists detected acute progressive left retro-orbital pressure followed by sudden inability to adduct the left eye, or a left medial rectus palsy, indicative of the ILT syndrome which led to immediate balloon deflation and resolution of the deficits. The hypothesis was that hypoperfusion of the ILT, an arterial branch of the ICA which provides blood supply to several cranial nerves (CN) III, CN V1 and CN V2, caused her acute symptoms.Although cerebral ischemia is a well known complication of endovascular procedures, CN ischemia is a rare potential risk. Knowledge of cerebrovascular anatomy and serial examinations prevented neurologic deficits; this case underscores the added utility of examinations by intraoperative monitoring neurologists and interdisciplinary collaboration.

  • An online diary for tracking epilepsy EPILEPSY & BEHAVIOR Le, S., Shafer, P. O., Bartfeld, E., Fisher, R. S. 2011; 22 (4): 705-709

    Abstract

    My Epilepsy Diary is a free Web-based application on the public website epilepsy.com, available for patients to track epilepsy and to aid clinicians with data-based, individualized management. The first aim of this descriptive study was to outline electronic diary functions. Second, the study retrospectively profiled a large cohort of 2010 calendar year diary users including demographics, seizure types, temporal distribution of seizures, triggers, and use and side effects of antiepileptic drugs (AEDs). A total of 1944 users provided demographic information and 1877 recorded seizure data. Most (64%) users were women. Average age was 29.9±16.0 years. A total of 70,990 seizure entries and 15,630 AED entries were logged. Events were apportioned as 79% seizures and 21% seizure clusters. Specific AEDs were detailed in 7331 entries: monotherapy was used in 18% and polytherapy in 82%. Mood-related side effects were most commonly reported in 19% of 1027 users.

  • Gelastic epilepsy and hypothalamic hamartomas: neuroanatomical analysis of brain lesions in 100 patients BRAIN Parvizi, J., Le, S., Foster, B. L., Bourgeois, B., Riviello, J. J., Prenger, E., Saper, C., Kerrigan, J. F. 2011; 134: 2960-2968

    Abstract

    Hypothalamic hamartomas present with isolated fits of ictal laughter (gelastic epilepsy) or a combination of gelastic and other types of seizures. Many of these patients also suffer from cognitive decline, neuropsychiatric comorbidities and precocious puberty. Although there is a large body of anecdotal evidence about hypothalamic hamartomas and gelastic seizures, many questions still remain to be answered. For instance, which specific hypothalamic regions are most affected by the location of hamartomas causing laughing versus other types of seizures? Does the neuroanatomical localization of the lesions differ in cases with only gelastic seizures or a combination of gelastic and other types of seizures? Does the location of the lesions correlate with the presence of precocious puberty, and does the type of lesion influence the severity or the type of seizures? In a retrospective review of clinical and structural neuroimaging data from 100 cases of gelastic epilepsy and hypothalamic hamartoma, we aimed to address these questions by analysing the clinical presentation and the neuroanatomical features of the hypothalamic lesions in these patients. Our findings suggest that in all 100 cases, lesions were centred at the level of the mammillary bodies in the posterior hypothalamus. Compared with the patients with pure gelastic seizures (n = 32), those with gelastic and other types of seizures (n = 68) had significantly longer duration of epilepsy (P < 0.001), whereas age of seizure onset, the volume of lesions and the proximity to the mammillary bodies were not different between the two groups. In contrast, patients with cognitive or developmental impairment and those with precocious puberty had significantly larger lesions involving the anterior and posterior hypothalamus.

  • Clinical Presentation and Long-Term Outcome of Cerebral Venous Thrombosis NEUROCRITICAL CARE English, J. D., Fields, J. D., Le, S., Singh, V. 2009; 11 (3): 330-337

    Abstract

    Despite recent advances, the clinical features of cerebral venous thrombosis (CVT) remain incompletely characterized. To our knowledge, no case series have been reported from North American centers with detailed long-term outcome data, and few studies have evaluated recanalization rates.All cases of CVT at a single tertiary care hospital between 1995 and 2004 were retrospectively reviewed. Follow-up information was obtained from direct patient interviews.Follow-up data were available for 58 of 61 CVT patients (median 50 months). Average age was 40, and 66% were women. Headache and focal neurological deficits were noted in 82% and 72%, respectively. Intracranial hemorrhage was seen in 44%. Hypercoagulable risk factors were identified in 84%. Anticoagulation was initiated acutely in 84%, including in all patients with intraparenchymal hemorrhage (IPH). The percentage of patients with a modified Rankin Score (mRS) of 0 to 2 at admission, hospital discharge and last follow-up were 41%, 67%, 90%, respectively; the rate of favorable long-term outcome did not differ significantly between patients with and without IPH. In the subset of 21 patients with follow-up imaging available for direct review, 90% had partial or complete recanalization.The demographics, clinical presentation, imaging findings, and risk factors in this large North American cohort of CVT patients strongly support the observations of previous European case series. In addition, the favorable long-term outcome and recanalization rates observed lend further support to the safety and efficacy of acute heparin therapy for the treatment of symptomatic CVT (irrespective of the presence of ICH).
