Objectives: To devise a clinical classification of children diagnosed with ASD according to etiologic workup.

Methods: Children diagnosed with ASD (n=436) from two databases were divided into groups of symptomatic, cryptogenic or idiopathic, and variables within each database and diagnostic category were compared.

Results: By analyzing the two separate databases, 5.4% of the children were classified as symptomatic, 27% as cryptogenic and 67.75% as idiopathic. Among other findings, the entire symptomatic group demonstrated language delays, but almost none showed evidence for regression. Our results indicate similarities between the idiopathic and cryptogenic subgroups in most of the examined variables, and mutual differences from the symptomatic subgroup. The similarities between the first two subgroups support prior evidence that most perinatal factors and minor physical anomalies do not contribute to the development of core symptoms of autism. Conclusions: Differences in gender and clinical and diagnostic features were found when etiology was used to create subtypes of ASD. This classification could have heuristic importance in the search for an autism gene(s).

Objectives: To examine the effect of seasonality, weather and holidays on hip fracture incidence in older adults. The study population comprised 2050 patients aged 65 years or more who sustained a proximal hip fracture.

Methods: The computerized files of the patients were reviewed for trends in incidence by season, precipitation, minimum and maximum temperatures, day of the week, and certain Jewish festivals.

Results: Hip fractures were more likely to occur in the winter than in the summer (P < 0.0001). Factors that significantly correlated with hip fracture were the maximum daily temperature (r = -0.746, P = 0.005) followed by the minimum daily temperature (r = -0.740, P = 0.006) and precipitation (r = 0.329, P = 0.02). There were fewer fractures on Saturdays (the Sabbath) as compared to other days of the week (P = 0.045). Researching the incidence on Jewish festivals, we found an elevated incidence on Passover (P < 0.0001) and a reduced incidence on the Day of Atonement (Yom Kippur) (P = 0.013).

Conclusions: In older people there is an elevated incidence of proximal hip fractures during the winter and on the Jewish festivals. On weekends and on the Day of Atonement the incidence of proximal hip fractures was reduced.

Objectives: To determine whether exposure to the Holocaust from preconception to early infancy is a cause of chronic morbidity in adulthood.

Methods: This pilot study involved 70 European Jews born in countries under Nazi rule (exposed group) during the period 1940–1945 who were interviewed to determine the presence of chronic diseases. A control group of 230 Israeli-born individuals of the same descent, age, and gender distribution were extracted from the Israel National Health Interview Survey-2 (unexposed group). The prevalence of selected risk factors and chronic diseases was compared between the groups.

Results: The prevalence of cardiovascular risk factors and morbidity was significantly higher in the exposed group: body mass index (BMI) (29.06 ± 3.2 vs. 26.97 ± 4.42, P = 0.015), hypertension (62.9% vs. 43%, P = 0.003), dyslipidemia (72.9% vs. 46.1%, P < 0.001), diabetes (32.9% vs. 17.4%, P = 0.006), angina pectoris (18.6% vs. 4.8%, P = 0.001) and congestive heart failure (8.6% vs. 1.7%, P = 0.013). The prevalence of cancer (30.0% vs. 8.7% P < 0.001), peptic ulcer disease (21.4% vs. 7%, P = 0.001), headaches/migraines (24.3% vs. 12.6%, P < 0.001) and anxiety/depression (50.0% vs. 8.3%, P < 0.001) was also higher in the exposed group.

Conclusions: These results suggest that exposure to Holocaust conditions in early life may be associated with a higher prevalence of obesity, dyslipidemia, diabetes, hypertension, cardiovascular morbidity, malignancy and peptic diseases in adulthood. These findings set the stage for further research, which might define those exposed as a high risk group for chronic morbidity.
