Skeletal muscle changes were evaluated in patients suffering from hemiparesis after stroke. Concentric needle EMG and single fiber EMG of the paretic gastrocnemius medialis muscle were performed. Maximal amplitude of H, T and M responses in calf muscles of both the affected and the unaffected sides were determined by usual electrophysiological techniques.(More)
The relationship between autonomic dysfunction and peripheral somatic neuropathy was investigated in uraemics. The battery of autonomic tests included R-R interval variation test, deep breathing, Valsalva manoeuvre, heart rate and blood pressure responses to standing, and sustained handgrip. Maximum conduction velocity along sensory and motor fibres of the(More)
A clinical and electrophysiological study evaluated the usefulness of local steroid therapy for carpal tunnel syndrome (CTS). To evaluate the efficacy of local steroid therapy 32 patients (53 nerves) were randomly assigned to one of two groups: one (27 nerves) received 15 mg methylprednisolone acetate injected locally and the other (26 nerves) received the(More)
IMPORTANCE Convergent biological, epidemiological, and clinical data identified urate elevation as a candidate strategy for slowing disability progression in Parkinson disease (PD). OBJECTIVE To determine the safety, tolerability, and urate-elevating capability of the urate precursor inosine in early PD and to assess its suitability and potential design(More)
We investigated involvement of the peripheral nervous system in 6 patients with amyotrophic chorea-acanthocytosis. Electromyographic and neurographic findings, and pathological changes as demonstrated by examination of biopsy specimens of muscle and sural nerve indicate that most patients had an axonal sensorimotor polyneuropathy with more pronounced(More)
IMPORTANCE New technologies are rapidly reshaping health care. However, their effect on drug development to date generally has been limited. OBJECTIVES To evaluate disease modeling and simulation, alternative study design, novel objective measures, virtual research visits, and enhanced participant engagement and to examine their potential effects as(More)
Ampicillin is considered a 'safe' drug in patients with neuromuscular transmission disorders although recently some doubt has been raised. The effect of ampicillin on neuromuscular transmission was studied in healthy subjects by means of single-fiber electromyography. A statistically significant increase of mean jitter value and of recordings with(More)
A battery of cardiovascular reflex tests were performed in 35 patients with chronic renal failure on intermittent haemodialysis. An impairment of parasympathetic control was found isolated (14%) or combined with a damage of sympathetic control of cardiovascular system (26%). Moreover, maximum conduction velocity along sensory and motor fibres of posterior(More)
BACKGROUND High-throughput approaches are increasingly being used to identify genetic associations across multiple phenotypes simultaneously. Here, we describe a pilot analysis that considered multiple on-treatment laboratory phenotypes from antiretroviral therapy-naive patients who were randomized to initiate antiretroviral regimens in a prospective(More)
Parkinson's disease is a complex heterogeneous disorder with urgent need for disease-modifying therapies. Progress in successful therapeutic approaches for PD will require an unprecedented level of collaboration. At a workshop hosted by Parkinson's UK and co-organized by Critical Path Institute's (C-Path) Coalition Against Major Diseases (CAMD) Consortiums,(More)
