A prevalence estimate of pervasive developmental disorder among immigrants to Israel and Israeli natives- a file review study.

BACKGROUND: The prevalence rates of pervasive developmental disorder (PDD) have risen in the West over the last 10 years. There is argument over the etiology of this change in rates. Social and cultural processes including migration have been hypothesized. Israel, as a country of ongoing immigration with a national registry of children diagnosed with PDD, offers an opportunity to compare rates of PDD among immigrants from developing countries and native Israelis. METHOD: A Social Security national registry of 1004 children diagnosed with PDD was reviewed and rates were calculated using data extracted from the Israel National Bureau of Statistics. Of all Jewish children that were born in the years 1983-1997 and who are currently living in Israel, we defined four groups: (1). native Israelis of non-Ethiopian extraction (N = 1198, 300), (2). native Israelis of Ethiopian extraction (N = 15600), (3). immigrants of non-Ethiopian extraction (N = 110300) and (4). children born in Ethiopia (N = 11800). A further breakdown of groups 1 and 3 by well-characterized ethnic or geographical origins was not possible. RESULTS: The rate of PDD was significantly elevated in native Israelis as compared to all immigrant children. Among immigrants, the rate of PDD in Ethiopian-born children was lower than that of those born in other countries. The rate of PDD in immigrant Ethiopian children was much lower than in native Israeli children of Ethiopian extraction. CONCLUSIONS: Birth in Israel, an industrialized country, is a marker for an environmental risk factor for PDD. This may indicate that gestation, birth or infancy in industrialized countries exposes children to environmental insults that increase the risk for contracting PDD.

Femur BMD bias associated with DPX-IQ reanalysis of DPX-acquired scan files.

Bone mineral density values calculated by DPX-IQ software reanalysis of original DPX software analyzed scans were compared at the femur region. Based on the results for 24 subjects each scanned on 12 different occasions, a significant bias at all sites--neck, Ward's triangle and trochanter--ranging from -0.7% (neck) to -2.1% (trochanter) was found. For the trochanter site 16 of the 24 subjects had significantly lower mean BMD values after DPX-IQ reanalysis, a trend also noted at the neck and Ward's triangle. Although it has been recommended that scans analyzed with DPX software do not require DPX-IQ reanalysis, our findings strongly indicate that DPX-IQ reanalysis is essential to minimize total error during follow-up BMD determinations.

FILEMAN41C--an interactive data management system for biomedical data selected from a free definable file by a pocket calculator.

An interactive system for the storage, retrieval and analysis of numerous clinical data is described. Due to the simple structure of the dialogue, no special knowledge of computer handling is required by the experimenter. The program is written for the Hewlett-Packard HP-41C pocket calculator and is suitable for a number of moderately sized experiments.
