This paper discusses positive therapeutic gains made with veterans whose primary treatment for posttraumatic stress disorder (PTSD) was artifact corrected neurofeedback. Assessments completed after both 20 and 40 halfhour sessions of treatment identified significant improvements for both auditory and visual attention using the IVA-2 and significant improvements in well-being based on the General Well-Being Scale (GWBS). It was discovered that neurofeedback impacted individuals' overall auditory attention and IVA-2 global auditory test scores significantly improved after both 20 (p < .007, Cohen's d = 0.5) and 40 training sessions (p < .0001, Cohen's d = 0.8). Veterans were found to have significant enhancements in auditory vigilance (p < .03), processing speed (p < .0009) and focus (p < .01). The IVA-2 global measure of visual attention was also found to show significant improvements after 20 sessions (p < .004, Cohen's d = 0.5) and after 40 sessions (p < .06, Cohen's d = 0.4). Specific improvements in visual processing speed (p < .04) and focus (p < .02) were identified after 40 sessions. Ratings of well-being significantly improved after treatment (p < .001, Cohen's d = 0.8) with 84% of the veterans improving five points or more on the GWBS. Improvements in well-being were found to be significantly correlated with increases in veterans' overall auditory attention (r = .44, p < .03) and auditory processing speed (r = .57, p < .005).

The 19 controls had non-malignant lung disease and, like the lung-cancer group, virtually all-were smokers (one exception); they were aged 47-82 (mean 66-2) and 12 were men. No patient was receivg steroids in any form or any other medication which might be expected to affect plasma sex hormone binding globulin concentratons.The table shows the results with both methods of measuring sex hormone binding globulin. Clearly there was no evidence at all for increased concentrations of sex hormone binding globulin in patients with lung cancer; indeed, the mean values in the patients with cancer were lower, albeit not significantly so. This was not due to our control group having higher values than the controls from the authors' study: our values for men Finally, it would be of interest to know more demographic data about the patients, such as age range, atopy, and what regular treatment they were using.In summary, the authors' findings need confirmation and clarificaton in a more precise prospective study, relating not only the incidence of acute asthma attacks but also the time ofpresentation (or time ofonset ofsymptoms, orboth) to the weather conditions during the preceding few hours. If confirmed the results would lend support to our hypothesis that certain combinations of meteorological factors can alter the level of bronchial hyperreactivity in patients with asthma.' At present the most likely factors are relative changes in temperature and relative humidity.
