The 40‐item Eating Attitudes Jest, the 26‐item Eating Attitudes Test, the Restrained Eating Inventory (El), and the Eating Disorders Inventory (EDI) were given to 81 women who were participating in an eating disorders study. The EAT‐26 totals and the scores of the three factors were intercorrelated. The scores of the EAT‐26 were also correlated with the scores of the EAT‐40, and El, and the EDI. The EAT‐26 correlated significantly with all three of its factors as well as with the EAT‐40. These results suggest that the EAT‐26 is a reliable and economical substitute for the EAT‐40. The EAT‐26 correlates highly with the eight subscales of the EDI and with the El, suggesting concurrent validity.

Introduction Catheter stability during atrial fibrillation ablation is associated with higher ablation success rates. Rapid cardiac pacing and high‐frequency jet ventilation (HFJV) independently improve catheter stability. Simultaneous modulation of cardiac and respiratory motion has not been previously studied. The objective of this study was to determine the effect of simultaneous heart rate and respiratory rate modulation on catheter stability. Methods Forty patients undergoing paroxysmal atrial fibrillation ablation received ablation lesions at 15 prespecified locations (12 left atria, 3 right atria). Patients were randomly assigned to undergo rapid atrial pacing for either the first or the second half of each lesion. Within each group, half of the patients received HFJV and the other half standard ventilation. Contact force and ablation data for all lesions were compared among the study groups. Standard deviation of contact force was the primary endpoint defined to examine contact force variability. Results Lesions with no pacing and standard ventilation had the greatest contact force standard deviation (5.86 ± 3.08 g), compared to lesions with pacing and standard ventilation (5.45 ± 3.28 g; P < .01) or to lesions with no pacing and HFJV (4.92 ± 3.00 g; P < .01). Lesions with both pacing and HFJV had the greatest reduction in contact force standard deviation (4.35 ± 2.81 g; P < .01), confirming an additive benefit of each maneuver. Pacing and HFJV together was also associated with a reduction in the proportion of lesions with excessive maximum contact force (P < .001). Discussion Rapid pacing and HFJV additively improve catheter stability. Simultaneous pacing with HFJV further improves catheter stability over pacing or HFJV alone to optimize ablation lesions.

Arthritis pain is a complex phenomenon involving intricate neurophysiological processing at all levels of the pain pathway. The treatment options available to alleviate joint pain are fairly limited and most arthritis patients report only modest pain relief with current treatments. A better understanding of the neural mechanisms responsible for musculoskeletal pain and the identification of new targets will help in the development of future pharmacological therapies. This article reviews some of the latest research into factors which contribute to joint pain and covers areas such as cannabinoids, proteinase activated receptors, sodium channels, cytokines and transient receptor potential channels. The emerging hypothesis that osteoarthritis may have a neuropathic component is also discussed.

Seven eating disorder groups were assessed via a self‐adjustable light beam for levels of body image distortion at seven body sites. Groups were catego‐ rized on the basis of present weight, past history of lowest weight, and pur‐ gative activity. The normal weight purging group had significantly higher body distortion levels on three body sites when compared to other clinical groups and control subjects. Results are discussed with regard to research in‐ dicating that body size distortion may not be specific to traditional anorexic categories.

The present study was designed to evaluate the effects of triazolam 0.5 mg on the sleep of insomniac patients when given for 3 weeks. The results showed that both acute and chronic triazolam administration are effective in decreasing sleep latency, increasing sleep duration, increasing sleep efficiency and decreasing total wake time without producing major effects on sleep staging. Sleep Stages 1 and 2 were significantly altered by drug treatment but in a positive direction. This change is primarily attributable to the significant decrease in sleep onset. Deep sleep and REM were not significantly changed during triazolam treatment nor was there any evidence of REM rebound after discontinuation of the medication. It was noted that some of the sleep parameters measured shifted toward baseline measures in the first night after triazolam treatment was terminated. However, the total recovery period recorded (7 days) showed the quality and quantity of sleep obtained to be improved over baseline measures. The recovery data compared favourably with those improvements noted during chronic administration of triazolam. It was also found that 3 weeks of triazolam 0.5 mg usage did not result in tolerance to its hypnotic properties. Thus, triazolam maintains its hypnotic effectiveness throughout 3 weeks of administration.
