Multiple sclerosis in diverse populations: characteristics in distinct Arab ethnicities in Israel.

Background: Multiple sclerosis (MS) prevalence and genetic susceptibility varies among the different ethnic groups of Jews and Arabs in Israel.

Objective: Characterization of MS disease course in Christian, Muslim and Druze Arabs in Israel.

Methods: Historical cohort and three-year follow-up cohort analyses based on interviews and clinical charts of 149 Arab MS patients (78 Muslims, 49 Christians and 22 Druze) from three MS centers in Israel.

Repeated electrophysiologic studies in patients with carpal tunnel syndrome following local corticosteroid injection using a novel approach.

Background: Local corticosteroid injection (LCI) for the treatment of carpal tunnel syndrome (CTS), using the classic method, is usually associated with improvement in different electrophysiologic parameters of the median nerve. However, there is no correlation between the clinical response and these electrophysiologic parameters.

Objectives: To evaluate the effect of our novel approach of LCI for the treatment of CTS on repeated electrophysiologic studies of the median nerve.

A novel approach of local corticosteroid injection for the treatment of carpal tunnel syndrome.

The objective of the study was to compare the favorable response rate, time duration, and pain level of local corticosteroid injection using a novel approach for the treatment of carpal tunnel syndrome vs a classic approach. Patients with symptomatic carpal tunnel syndrome of less than 1-year duration were randomized for local corticosteroid injection using either the classic approach or a novel approach. In our approach (novel), we used a 29 gauge x 1/2-in.
