Myasthenia in pregnancy: best practice guidelines from a U.K. multispecialty working group.
A national U. K. workshop to discuss practical clinical management issues related to pregnancy in women with myasthenia gravis was held in May 2011. The purpose was to develop recommendations to guide general neurologists and obstetricians and facilitate best practice before, during and after pregnancy. The main conclusions were (1) planning should be instituted well in advance of any potential pregnancy to allow time for myasthenic status and drug optimisation; (2) multidisciplinary liaison through the involvement of relevant specialists should occur throughout pregnancy, during delivery and in the neonatal period; (3) provided that their myasthenia is under good control before pregnancy, the majority of women can be reassured that it will remain stable throughout pregnancy and the postpartum months; (4) spontaneous vaginal delivery should be the aim and actively encouraged; (5) those with severe myasthenic weakness need careful, multidisciplinary management with prompt access to specialist advice and facilities; (6) newborn babies born to myasthenic mothers are at risk of transient myasthenic weakness, even if the mother's myasthenia is well-controlled, and should have rapid access to neonatal high-dependency support.

Comparative StudyMedical therapy and subthalamic deep brain stimulation in advanced Parkinson's disease: a different long-term outcome?
Few clinical trials reported the comparative short-term efficacy of subthalamic nucleus deep brain stimulation (STN-DBS) versus medical therapy in advanced Parkinson's disease (PD). However, the comparative efficacy, safety and the potential disease-modifying effect of these treatments have not been investigated over a longer follow-up period. ⋯ To our knowledge, this is the first long-term comparison between medical and surgical therapies; a superior efficacy of STN-DBS was observed on motor disability, while no significant differences were observed in the progression of motor symptoms and, apart from phonemic verbal fluency, of neuropsychological alterations.

Novel C12orf65 mutations in patients with axonal neuropathy and optic atrophy.
Charcot-Marie Tooth disease (CMT) forms a clinically and genetically heterogeneous group of disorders. Although a number of disease genes have been identified for CMT, the gene discovery for some complex form of CMT has lagged behind. The association of neuropathy and optic atrophy (also known as CMT type 6) has been described with autosomaldominant, recessive and X-linked modes of inheritance. Mutations in Mitofusin 2 have been found to cause dominant forms of CMT6. Phosphoribosylpyrophosphate synthetase-I mutations cause X-linked CMT6, but until now, mutations in the recessive forms of disease have never been identified. ⋯ This work describes a mutation in the C12orf65 gene that causes recessive form of CMT6 and confirms the role of mitochondrial dysfunction in this complex axonal neuropathy.

Cognitive deficits in mild Parkinson's disease are associated with distinct areas of grey matter atrophy.
The neuroanatomical substrates underlying cognitive impairment in Parkinson's disease (PD) remain poorly understood. To address this gap, we compared the grey matter atrophy patterns in PD patients with mild cognitive impairment (PD-MCI) with PD patients having no cognitive impairment (PD-NCI), and examined relationships between atrophic regions and cognitive performance in specific domains. ⋯ Domain specific cognitive impairment in mild PD is associated with distinct areas of grey matter atrophy. These regions of atrophy are demonstrable early in the disease course and may serve as a biomarker for dementia in PD.
