Ultrasound of inherited vs. acquired demyelinating polyneuropathies.
We compared features of nerve enlargement in inherited and acquired demyelinating neuropathies using ultrasound. We measured median and ulnar nerve cross-sectional areas in proximal and distal regions in 128 children and adults with inherited [Charcot-Marie-Tooth-1 (CMT-1) (n = 35)] and acquired [chronic inflammatory demyelinating polyneuropathy (CIDP) (n = 55), Guillaine-Barre syndrome (GBS) (n = 21) and multifocal motor neuropathy (MMN) (n = 17)] demyelinating neuropathies. We classified nerve enlargement by degree and number of regions affected. ⋯ Ultrasound identified patterns of diffuse nerve enlargement can be used to screen patients suspected of having CMT-1. Normal, mildly, or regionally enlarged nerves in demyelinating polyneuropathy suggests an acquired etiology. Early treatment in CIDP may impede nerve enlargement.

Potential impact of self-perceived prodromal symptoms on the early diagnosis of Parkinson's disease.
The detection of Parkinson's disease (PD) at stages earlier than current diagnostic criteria allow for may increase the efficacy of disease-modifying therapies. Here we studied the relationship between retrospectively reported prodromal non-motor and motor features of PD, their pre-diagnostic presentation to physicians, and the extrapolated potential of an earlier diagnosis of PD considering early diagnostic markers detected at presence. One hundred and fifteen PD patients (41 women; age 63.2 ± 8.6 years) underwent a structured face-to-face interview on 22 prediagnostic symptoms. ⋯ In the prediagnostic phase, 99 % of patients consulted a physician because of motor symptoms but only 36 % with non-motor symptoms, mostly pain (20 %), depression/anxiety (9 %), constipation, bladder urgency, insomnia, REM sleep behaviour disorder, sexual dysfunction, and malignant melanoma (each, <6 %). Assuming the potential detectability of present hyposmia, asymmetric motor slowing and SN-h, a triad highly specific for PD, as early as 5 years prior to diagnosis, up to 84 (73 %) patients could have been identified in the prediagnostic phase using their or their physicians' awareness of early symptoms. We conclude that educating the general population and physicians on the importance of distinct prodromal features and applying symptom-specific diagnostic programs can improve the early detection of PD.

Lacosamide (LCM) is a treatment option for status epilepticus (SE) described in several series. We therefore proposed to describe its use in status epilepticus patients in our hospital. All patients admitted to our hospital for SE from September 2010 to April 2012 were evaluated. ⋯ LCM is a useful drug that represents an alternative in the treatment of non-convulsive or focal motor SE. Its efficacy might be more important when it is administered as a second or third option after benzodiazepines. A randomized trial is required to confirm these results.

Randomized Controlled Trial Multicenter StudyLong-term effects of tafamidis for the treatment of transthyretin familial amyloid polyneuropathy.
Tafamidis, a transthyretin (TTR) kinetic stabilizer, delayed neuropathic progression in patients with Val30Met TTR familial amyloid polyneuropathy (TTR-FAP) in an 18-month randomized controlled trial (study Fx-005). This 12-month, open-label extension study evaluated the long-term safety, tolerability, and efficacy of tafamidis 20 mg once daily in 86 patients who earlier received blinded treatment with tafamidis or placebo. Efficacy measures included the Neuropathy Impairment Score in the Lower Limbs (NIS-LL), Norfolk Quality of Life-Diabetic Neuropathy total quality of life (TQOL) score, and changes in neurologic function and nutritional status. ⋯ AEs were similar between groups; no patients discontinued because of an AE. Long-term tafamidis was well tolerated, with the reduced rate of neurologic deterioration sustained over 30 months. Tafamidis also slowed neurologic impairment in patients previously given placebo, but treatment benefits were greater when tafamidis was begun earlier.

Randomized Controlled TrialHigh-rate repetitive transcranial magnetic stimulation in migraine prophylaxis: a randomized, placebo-controlled study.
Repetitive transcranial magnetic stimulation (rTMS) is an emerging treatment for pain but there is no class 1 study on its role in migraine prophylaxis. In this study we report the efficacy and safety of high-rate rTMS in migraine prophylaxis. Adult migraine patients having >4 attacks/month were randomized to high-rate rTMS or sham stimulation. ⋯ Functional disability also improved significantly in rTMS group (P = 0.0001). Only one patient following rTMS developed transient drowsiness and was withdrawn from the study. This study provides evidence of the efficacy and safety of 10 Hz rTMS in migraine prophylaxis.
