Relationship between child abuse history, trauma, and dissociation in Russian college students

OBJECTIVE: The research was conducted to determine the relationship between violent trauma, child abuse history, and dissociative symptoms in a Russian population. METHOD: Three hundred and one undergraduate students from Moscow State Linguistics University participated in the study and completed the Dissociation Continuum Scale, the Violence History Questionnaire, the Traumatic Events Survey (TES), and a demographic measure. RESULTS: Scores on dissociation and its subfactors were significantly higher in the Russian sample compared to the normative US group. The best predictors for dissociation were experiencing a violent trauma, child abuse history, and/or the experience of a fearful event. Those participants with a prior child abuse history were more symptomatic after adult trauma than those with no such history. CONCLUSIONS: The relationship between trauma/abuse and dissociation is unlikely to be a result of suggestion by therapists or media exposure, since the correlation appears in a Russian population who are relatively unexposed to these suggestive sources. The validity, reliability, and structure of the dissociation measure were relatively similar in American and Russian samples.     

Back pain/discomfort in pregnancy: invisible and forgotten

This paper is a comprehensive literature review of original research on the nature of back pain/discomfort in pregnancy. The causes of back pain/discomfort in pregnancy are reviewed and discussed, and the clinical manifestations and implications are explored. This analysis revealed that approximately 50% of pregnant women experience back pain/discomfort with little or no intervention from their health care providers. Thus, back pain/discomfort in pregnancy seems to be invisible and forgotten in contemporary antenatal care. Evidence-based guidelines are provided for both women and health professionals as a way of increasing attention to the prevention of unnecessary back pain/discomfort during pregnancy.     

Eye movement patterns of captioned television viewers

Eye movement of six subjects was recorded as they watched video segments with and without captions. It was found that the addition of captions to a video resulted in major changes in eye movement patterns, with the viewing process becoming primarily a reading process. Further, although people viewing a specific video segment are likely to have similar eye movement patterns, there are also distinct individual differences present in these patterns. For example, someone accustomed to speechreading may spend more time looking at an actor's lips, while someone with poor English skills may spend more time reading the captions. Finally, there is some preliminary evidence to suggest that higher captioning speed results in more time spent reading captions on a video segment.     

Time spent viewing captions on television programs

The eye movements of 23 deaf subjects, ages 14 to 61 years, were recorded 30 times per second while the subjects watched four 2.5-minute captioned television programs. The eye movement data were analyzed to determine the percentage of time each subject actually looked at the captions on the screen. It was found that subjects gazed at the captions 84% of the time, at the video picture 14% of the time, and off the video 2% of the time. Age, sex, and educational level appeared to have little influence on time spent viewing captions. When caption speed increased from the slowest speed (100 words per minute, or wpm) to the fastest speed (180 wpm), mean percentage of time spent gazing at captions increased only from 82% to 86%. A distinctive characteristic of the data was the considerable variation from subject to subject and also within subjects (from video to video) in regard to percentage of time spent gazing at captions.     

Test-taking skills: a missing component of deaf students' curriculum

Often, conclusions about what students have learned in school are based on their performance on standardized or informal tests. For several reasons, these tests may not accurately reflect deaf students' learning. The author discusses the limitations of tests and other "products" administered to students during or after reading that are interpreted as reflecting comprehension of what is read. The author also reviews documented differences in test-taking abilities of deaf and hearing students, and describes specific compensatory test-taking strategies used by deaf readers. A rationale is provided for including a formal test-taking skills component in the curriculum for deaf students. Finally, the author discusses portfolio assessment and contemporary societal forces working against academic testing.

Three Cases of Lead Toxicity Associated with Consumption of Ayurvedic Medicines

Ayurveda is a traditional form of medicine used by majority of the Indians. Here we report three cases of lead toxicity, following intake of Ayurvedic medicines. Three patients presented with blood lead levels (BLLs) of 122.4, 115 and 42.8 μg/dl respectively at the time of hospitalization. The first case was chelated with D- penicillamine, the second with calcium disodium ethylene diamino tetra acetate (EDTA) and the third with environmental intervention and education. Associated Ayurvedic products were collected from patients and analyzed for metallic concentration. Cessation of Ayurvedic medication along with chelation, nutritional intervention and education, reduced the BLL to 27.4 μg/dl in the first case after 1 year, 21.1 μg/dl after 9 months in the second and 18.2 μg/dl after 6 months in the third case.
