Prospective study of clinical, neurophysiological and urodynamic findings in multiple sclerosis patients undergoing percutaneous transluminal venous angioplasty.

Objective: Verify whether Percutaneous Transluminal Angioplasty (PTA) may affect neural conduction properties in Multiple Sclerosis (MS) patients, thereby modifying patients' disability, with prospective neurophysiological, urodynamic, clinical and subjective well-being evaluations.

Methods: In 55 out of 72 consecutively screened MS patients, the following procedures were carried out before (T0), at 2-6 months (T1) and at 6-15 months (T2) after a diagnostic phlebography, eventually followed by the PTA intervention if chronic cerebrospinal venous insufficiency (CCSVI) was diagnosed: clinical/objective evaluation (Expanded Disability Status Scale, EDSS), ratings of subjective well-being, evaluation of urodynamic functions and multimodal EPs (visual, acoustic, upper and lower limbs somatosensory and motor evoked potentials).

Results: The number of dropouts was relatively high, and a complete set of neurophysiological and clinical data remained available for 37 patients (19 for urological investigations).

Factors influencing the diagnostic process of carpal tunnel syndrome.

There are no studies regarding the course leading to carpal tunnel syndrome (CTS) diagnosis and factors influencing the diagnostic process. The study aim is to analyse CTS diagnostic path assessing whether the type of physician (general practitioners or specialist) may influence the manner and timing of diagnosis, and whether CTS severity at diagnosis may be predicted by factors related to Public Health Service and/or to patient. A medical history form was filled in by 375 consecutive patients with idiopathic CTS enrolled at an electromyography service.

Sympathetic skin response. Glabella stimulation may be more useful than peripheral nerve stimulation in clinical practice.

The aim is to verify whether glabella electrical stimulation evokes sympathetic skin responses (SSR) without inter-side differences in latency and area of the responses and is more useful in mononeuropathies than peripheral nerve stimulation. SSRs were recorded in 25 healthy subjects from right palm, third (M3SSR) and fifth fingers and contralateral third finger. The inter-side differences of grand mean area and mean of largest area of M3SSR were significant only by ulnar nerve and not by glabella stimulation.

Incidence of ulnar neuropathy at the elbow in the province of Siena (Italy).

Background: Although ulnar neuropathy at the elbow (UNE) is the second most frequent focal peripheral neuropathy of the upper limb after carpal tunnel syndrome (CTS), no figures on its prevalence or incidence in the general population have been reported.

Objective: To determine the incidence of UNE in a general population.

Methods: Retrospective study to identify newly diagnosed cases on the basis of clinical symptoms or signs and slowing of motor conduction velocity of the ulnar nerve across the elbow or surgical evidence of nerve compression in the elbow region.

Mononeuropathies of the radial nerve: clinical and neurographic findings in 91 consecutive cases.

Retrospective features of 91 consecutive cases (68 men, 23 women; mean age 44.4 years) of radial mononeuropathy diagnosed over the last 8 years in two electromyography (EMG) services are reported to define the clinical and electrophysiological findings of radial neuropathies in relation to traumatic and non-traumatic causes and site of injury. The occurrence of radial neuropathy was 0.
