Randomized Controlled TrialAssessing the risk of subsequent tonic-clonic seizures in patients with a history of simple or complex partial seizures.
Patients who present with only simple or complex partial seizures have a poorly documented prognosis. Treatment may be advocated to prevent future secondary generalised seizures, reduce the frequency of further simple or complex partial seizures or a combination of both. ⋯ Patients presenting with a history of only partial seizures are at low risk of subsequent tonic-clonic seizures in the period of time to which therapeutic decisions are relevant. The effects of the antiepileptic drugs used in the MESS study are greater for tonic-clonic seizures than they are for partial seizures.

Increased risk of multiple sclerosis relapse after in vitro fertilisation.
Exogenous sexual steroids together with pregnancy have been shown to influence the risk of relapses in multiple sclerosis (MS). Treatments used during assisted reproductive techniques may consequently influence the short term evolution of MS by modifying the hormonal status of the patient. The objective of this study was to determine if there was an increased risk of developing exacerbations in women with MS after in vitro fertilisation (IVF). ⋯ An increased relapse rate was observed in this study after IVF in patients with MS and may be partly related both to IVF failure and the use of GnRH agonists.

Thalamic sensory strokes with and without pain: differences in lesion patterns in the ventral posterior thalamus.
Vascular lesions of the posterolateral thalamus typically result in a somatosensory syndrome in which some patients develop central neuropathic post-stroke pain (CPSP). Damage to the spinothalamic tract terminus is assumed to be a prerequisite for thalamic CPSP. At the nuclear level, it remains a matter of debate whether the ventral posterolateral nucleus (VPL) or the posterior portion of the ventral medial nucleus (VMpo) constitutes the decisive lesion site. The hypothesis of the study was that lesion location in thalamic CPSP patients differs from that in thalamic stroke patients without pain, and the aim was to identify whether this difference comprises the VPL and/or the VMpo. ⋯ This study specifies the role of the VPL in thalamic CPSP and shows that the posterolateratal and inferior parts in particular are critically lesioned in pain patients. In this thalamic subregion, afferents of the spinothalamic tract are known to terminate. In contrast, the data do not support a pivotal impact of the VMpo on thalamic CPSP.

(1) To study the neuropsychological and psychopathological profile in myoclonus-dystonia (M-D) patients with and without a mutation in the DYT11 gene. (2) To explore whether cognitive and psychiatric impairments are related to severity and duration of motor symptoms. Herewith, this study may help to clarify whether neuropsychological and psychiatric symptoms are associated with the DYT11 mutation or are secondary to the burden of motor impairments that originated in early childhood. ⋯ The findings of this study suggest that anxiety disorders and executive dysfunctions may be part of the phenotype of M-D patients with a DYT11 mutation, whereas depressive symptoms and semantic fluency impairments may be secondary to suffering from a chronic movement disorder, regardless of DYT11 gene mutation.
