The rise and fall of fasciculations in amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis is a devastating neurodegenerative disease with a median survival of 3 years from symptom onset. Accessible and reliable biomarkers of motor neuron decline are urgently needed to quicken the pace of drug discovery. Fasciculations represent an early pathophysiological hallmark of amyotrophic lateral sclerosis and can be reliably detected by high-density surface electromyography.

UK case control study of smoking and risk of amyotrophic lateral sclerosis.

: Susceptibility to amyotrophic lateral sclerosis (ALS) is associated with smoking in some studies, but it is not clear which aspect of smoking behavior is related. Using detailed records of lifetime smoking we investigated the relationship between smoking and ALS in a UK population. : In this retrospective case-control study, smoking status was collected using environmental questionnaires from people diagnosed with ALS between 2008 and 2013 and from age, sex and geographically matched controls.

Remarkable motor recovery after riboflavin therapy in adult-onset Brown-Vialetto-Van Laere syndrome.

The clinical diagnosis of Brown-Vialetto-Van Laere syndrome in this woman with rapidly progressive pontobulbar palsy led to empirical high-dose oral riboflavin (1200 mg/day) therapy. This resulted in a dramatic improvement in her motor function from being anarthric, dysphagic, tetraparetic and in ventilatory failure to living independently with mild dysarthria and distal limb weakness. DNA sequencing of the SLC52A3 gene found compound heterozygous C-terminus mutations, V413A1/D461Y, consistent with recent reports of mutations within the riboflavin transporter genes (SLC52A2 and SLC52A3) in this condition.

Homozygosity analysis in amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) may appear to be familial or sporadic, with recognised dominant and recessive inheritance in a proportion of cases. Sporadic ALS may be caused by rare homozygous recessive mutations. We studied patients and controls from the UK and a multinational pooled analysis of GWAS data on homozygosity in ALS to determine any potential recessive variant leading to the disease.

The sex ratio in amyotrophic lateral sclerosis: A population based study.

Replicable risk factors for ALS include increasing age, family history and being male. The male: female ratio has been reported as being between 1 and 3. We tested the hypothesis that the sex ratio changes with age in a population register covering the south-east of England.

No association of DPP6 with amyotrophic lateral sclerosis in an Italian population.

We have attempted to replicate a recently reported association of polymorphism rs10260404, in the Dipeptidyl-peptidase 6 gene (DPP6), with susceptibility to amyotrophic lateral sclerosis (ALS) in a large independent Italian cohort of 904 cases and 1036 controls. Minor allele frequency was 0.38 in cases and 0.

Comparison of two percutaneous radiological gastrostomy tubes in the nutritional management of ALS patients.

Patient care and minimizing complications post gastrostomy have to date received little attention in ALS patients. We compare the complications associated with pigtail and mushroom type percutaneous radiological gastrostomy tubes in this patient group. Patients requiring PRG received either Wills-Oglesby or the skin level Entristar.
