Keeping kids safe: caregivers' perspectives on the determinants of physical activity in rural Indigenous communities.

Introduction: Physical activity is one way to ameliorate the disproportionately high obesity rates among Indigenous children yet little is known about the determinants of physical activity in First Nation communities.

Methods: A socioecological approach was used to explore the determinants that influence physical activity among Indigenous children in six First Nation communities in north-eastern Ontario, Canada. A thematic analysis of eight focus groups with 33 caregivers of Indigenous children was conducted.

[Comparison between the terminal motor pudendal nerve terminal motor latency, the localization of the perineal neuralgia and the result of infiltrations. Analysis of 53 patients].

Aim: The aim is to study the value of the pudendal nerve terminal motor latency (PNTML) testing, in respect to the painful side in patients with pudenda neuralgia, and to determine whether a possible increased latency in the painful side is predictive of a good result with the infiltration.

Method: This retrospective study included 53 outpatients (42 women, mean age 62) with suffering from pudendal neuralgia, who were seen between 2000 and 2004. The mean duration of the pain was 30+/-47 months.

Magnetoencephalographic studies of two cases of diffuse subcortical laminar heterotopia or so-called double cortex.

Two cases (a young male and a girl, suffering intractable epilepsy) of diffuse subcortical laminar heterotopia, or so-called double cortex (DC) have been investigated using magnetoencephalography (MEG). MEG confirmed involvement of both cortices (hetero- and normocortex) in the genesis of interictal spikes, and, according to the heterogeneity of DC syndrome, some differences were observed: spike initiation in the normocortex and latter involvement of the heterotopic cortex in the man, and rather a cancellation in both cortices in the girl. In addition, participation of heterotopic cortex in physiological activities could be demonstrated in the man.

Magnetoencephalography in stroke: a 1-year follow-up study.

Recovery after stroke is closely linked to cerebral plasticity. Magnetoencephalography (MEG) is a non-invasive technique, which allows location of cerebral cells activities. In the present work, a cohort of patients has been studied with MEG.

Non-supervised spatio-temporal analysis of interictal magnetic spikes: comparison with intracerebral recordings.

Objective: Our main goal was to evaluate the accuracy of an original non-supervised spatio-temporal magnetoencephalography (MEG) localization method used to characterize interictal spikes generators.

Methods: MEG and stereotactic intracerebral recordings (stereo-electro-encephalographic exploration, SEEG) data were analyzed independently in 4 patients. MEG localizations were performed with and without anatomical constraints.
