Is season of birth associated with multiple sclerosis?

Objective - To compare the monthly distribution of multiple sclerosis (MS) patients' births with that of the Sicilian population. Background -Studies on the association between season of birth and risk of MS are scanty and controversial. Design and methods - Archives of the Institute of Neuropsychiatry of the Universities of Palermo and Catania were searched up to 1995 for definite MS patients (McDonald & Halliday criteria). The monthly distribution of MS patients' births (N=965) was compared with that of the Sicilian population (N = 5,608,307). Results -The distribution of births among MS patients compared with the general population was not different when tested by the X 2 statistic (P > …

Intravenous gammaglobulin treatment in chronic progressive multiple sclerosis

Incidence of multiple sclerosis in Bagheria City, Sicily, Italy.

We investigated the incidence of multiple sclerosis (MS) in a Sicilian community located at sea level. The study was a retrospective search for MS patients. Incidence was studied in the period from 1 January 1985 to 31 December 1994. We searched for definite MS patients, according to Poser's criteria, among the population resident in Bagheria (Palermo province). There were 25 subjects affected by MS, of which 20 were incident MS patients. The average annual incidence was 4.4 per 100 000 persons (n = 453 385 person-years). The incidence increased over time (1985-1989 = 3.5, 1990-1994 = 5.3). A parallel decrease of the interval between onset and diagnosis of MS was observed (1985-1989, 3.7 ye…

A transcranial magnetic stimulation study evaluating methylprednisolone treatment in multiple sclerosis

Objective - To investigate the efficacy of two different high doses of intravenous methylprednisolone (IVMP) during Multiple Sclerosis (MS) relapses. Background - Transcranial Magnetic Stimulation (TMS) is the most sensitive neurophysiological ascertainment to quantify motor disability, to follow the recovery from an MS relapse, and to detect the response to treatment. Design and method - Twenty-four clinically definite relapsing - remitting MS patients presenting a relapse were randomly assigned to a treatment for 5 days with IVMP 1 or 2 g/day. The response to treatment of each patient was evaluated through Expanded Disability Status Scale (EDSS), Medical Research Council (MRC) score, and …
