Abstract

We report a case of delayed postanoxic encephalopathy (DPE) studied with serial diffusion weighted imaging five times in a one-year period along with apparent diffusion coefficient (ADC) map as well as ADC values of periventricular white matter. Compared to the normal value, the ADC values of the white matter were initially low on the three (0.68 +/- 0.08 x 10(-3) mm(2)/s) and seven-week images (0.67 +/- 0.08 x 10(-3) mm(2)/s) but gradually recovered to the normal range on the four, six, and twelve-month images (0.78 +/- 0.05, 0.80 +/- 0.05 and 0.87 +/- 0.11 x 10(-3) mm(2)/s, respectively). Among the several pathogenetic mechanisms associated with DPE, these serial changes may be consistent with cytotoxic edema, from apoptosis, triggered by hypoxia.

Perceived quality of life of adults with developmental and other significant disabilities.

PURPOSE: The purpose of this qualitative study was to describe the perceived quality of life (PQOL) of adults with significant disabilities who were living in community settings. METHODS: Six male and six female volunteers (mean age 48 years, standard deviation 14 years), half with developmental and half with acquired disabilities, were interviewed about their quality of life. The interviews were audio-taped and transcribed verbatim. Text units were identified in the narrative data and were coded, sorted, and entered in an Index Tree. Data analysis utilized the Constant Comparison Technique with underlying themes emerging in 11 areas. RESULTS: The highest PQOL was noted in Health and Housing; the lowest in Transportation/Physical Accessibility and Employment. Deficits in Transportation/Physical Accessibility compromised PQOL in other areas. In regards to employment, seasonal, part-time and occasional work were common, and assistive technology and computers were rarely used to enhance employment capabilities. PQOL depended on the availability of appropriate supports and services, and tended to differ between those with developmental and those with acquired disabilities. CONCLUSION: Policy makers and advocacy groups could best improve the PQOL for those with severe disabilities by facilitating transportation and employment services.

Cognitive mechanisms, psychosocial functioning, and neurocognitive rehabilitation in schizophrenia.

The aim of the present study is to test Brenner's model of cognitive functioning in schizophrenia. It is assumed that elementary cognitive disorders (attention and encoding) and complex cognitive disorders (recall, concept formation) reinforce each other. Cognitive disorders are supposed to cause detrimental effects on functional outcome. We used cognitive rehabilitation as a strategy to induce cognitive changes in 27 patients assigned to treatment groups following the cognitive modules of the Integrated Psychological Treatment (IPT). Ten schizophrenic patients without cognitive impairments worked as a control group. With only one minor conceptual change (replacing concept formation with executive function, a more comprehensive construct), we found that our data fitted with Brenner's model. A relationship has been found between neuropsychological improvements and higher levels of autonomy and social functioning. These findings have important implications not only for cognitive assessment but also for selecting targets in cognitive rehabilitation.

Associations between attitudes toward hormone therapy and current use of it in middle-aged women.

OBJECTIVES: To investigate the association between attitudes toward hormone therapy (HT) and use of it and explanatory factors for the association found. METHODS: All women in two primary healthcare districts aged 45, 50, 55 or 60 in 2000 or 2001 (n=771) received a questionnaire consisting of quality-of-life instruments and items concerning menopause, health, healthcare, symptoms, sociodemographic factors and attitudes toward HT. RESULTS: A total of 564 women (74%) responded to the questionnaire. In the women with a positive or a neutral attitude, rather than a negative one, the age- and menopause-adjusted odds ratios for current HT use were 18.55 (95% CI 8.55, 40.11) and 2.61 (1.15, 5.93), respectively. Health-related factors, factors concerning one's own person and psychosocial factors were the groups of factors found to contribute to explaining the association between attitudes and current HT use. Together, the three groups of factors explained 42 and 98%, respectively, of a positive and a neutral attitude's association with current use of HT. Individual factors of importance in these factor groups were a feeling of being appreciated outside the home, satisfaction with one's work, marital status, own climacteric period, visits to a physician and past use of hormonal contraceptives. In contrast, level of education and the occurrence of cold sweats/hot flushes was not found to contribute to the explanation. CONCLUSIONS: Factors concerned with women's everyday life, contentment with oneself and use of healthcare services were of importance in explaining the associations between attitudes toward HT and current use of it. Consideration at these factors in counselling women about HT is recommended.
