There have been few population-based studies of acute transverse myelitis (ATM). Therefore, incidence and population selectivity of this disorder in different regions is not well known. Data on all Jewish patients with ATM throughout Israel were collected for the period 1955 through 1975. Based on 62 patients who satisfied rigid diagnostic criteria, the(More)
The incidence of amyotrophic lateral sclerosis (ALS) in Israel was determined for the period 1959 through 1974. A total of 246 patients with ALS was ascertained. The male-female ratio was 1.62:1. The average annual age-adjusted incidence per 100,000 persons increased during this period by 41%. The increase was almost entirely due to a higher rate in persons(More)
A growing body of evidence suggests that Alzheimer's disease (AD) is associated with local inflammation processes, including the activation of inflammatory cytokines. We performed a case-control association study between sporadic AD patients and the exon 5 position +3953 polymorphism in the potent pro-inflammatory cytokine, interleukin-1beta (IL-1B). Recent(More)
PrP(Sc), an aberrantly folded protein, is the only identified component of the prion, an agent causing fatal neurodegenerative diseases such as scrapie and bovine spongiform encephalopathy. Dimethyl sulfoxide (DMSO) has been shown to reduce the accumulation of PrP(Sc) in scrapie-infected (ScN2a) cells, and to inhibit its aggregation in vitro. In humans,(More)
All identified Israeli patients with amyotrophic lateral sclerosis (ALS) with onset of the disease from 1959 through 1975 (n = 318) were evaluated clinically. Most of our patients (63%) presented with weakness; only 10% presented with atrophy and 3% with fasciculations. In 31% of the cases, the onset of the disease was focal and 22% of the patients(More)
This case-control study was aimed at identifying environmental risk factors for multiple-sclerosis (MS). Ninety-three Israeli-born MS patients identified in country-wide studies and 94 age- and sex-matched controls were interviewed. The questionnaire covered a large span of factors at ages 0, 10 and onset of the disease, with particular emphasis on(More)
The incidence and prevalence of multiple sclerosis (MS) were compared, controlling for age, in native-born Israelis of different origins and in immigrants to Israel. This comparison was carried out in two populations, countrywide and in Jerusalem. In the countrywide population, ascertainment was based mainly on hospitalizations; it included 252 patients who(More)
In Israel, SSPE has been shown to be much more frequent among Sephardic Jews and Arabs than among Ashkenazic Jews. In the present study, we tried to explore environmental factors that may be of etiological importance and explain these differences in prevalence. The study is a case-control one, which includes 95 patients and 2 groups of controls, with 95(More)
The relation between birth order and risk of multiple sclerosis (MS) was studied among MS patients in Israel. The evaluation was both by case-control study and comparison of expected and observed birth order in Israel-born patients. Results showed an excess of first-born and a low birth order among MS patients. Conversely, in MS patients born abroad but who(More)
