Occupation and bladder cancer risk.

This study examines the estimated risk of bladder cancer associated with various occupations among 1,465 cases identified in Orange County, California, during 1984-1988. The annual age-adjusted incidence rate per 100,000 population in Orange County was similar to that of the Surveillance, Epidemiology, and End Results Program of the National Cancer Institute: 25.7 in males and 6.2 in females. Cases were compared with a sample of Orange County residents relative to broad category of current occupation, adjusted for age and cigarette smoking. The estimated relative risks were significant for males in machine trades (relative risk (RR) = 2.69, 95% confidence interval (CI) 1.24-5.82) and processing occupations (RR = 5.77, 95% CI 1.43-23.27) and for females in machine trades (RR = 8.34, 95% CI 1.14-61.17) and homemakers (RR = 5.37, 95% CI 2.40-11.99) as compared with individuals of the same sex in professional, technical, and managerial occupations.

Multiple rheumatoid nodules of the renal cortex.

We report the findings of a large localized collection of rheumatoid nodules in the renal cortex of a male patient with long-standing seropositive rheumatoid arthritis. Rheumatoid nodules are a rare occurrence in the urinary tract, with only two previous reports of renal involvement, to our knowledge. A possible relationship, on the basis of immunologically mediated mechanisms, to accompanying chronic pyelonephritis is proposed.

Is event frequency encoded automatically? The case of alcohol intoxication.

The four experiments reported show that sensitivity to event frequency is diminished by alcohol intoxication. In two experiments on confusion between presented and generated words, the function relating estimated to actual frequency was steeper for sober than intoxicated subjects. In two experiments on word-frequency estimates after a word-pronunciation task, the influence of alcohol intoxication was identified at the input as opposed to the test stage. We conclude that these findings are inconsistent with the idea that frequency-of-occurrence information is automatically encoded.

Anti-HTLV III ELISA and Western blot testing in a blood donor population: implications for donor notification.

We have evaluated the western blot (WB) test for distinguishing anti-HTLV III ELISA-positive donors who have likely been exposed to HTLV III from those that are false positives. Of 1,955 donors, 26 were positive for anti-HTLV III by ELISA testing. Only 6 (23%) were positive by WB: 5 of these 6 were male homosexuals with multiple partners and 5 of 6 had low Th/Ts ratios. The WB-positive donors gave the highest absorbance values in the anti-HTLV III ELISA assay. The immunologic abnormalities in the WB-positive donors suggest that they should be notified of their test results. We conclude that basing a donor notification policy on WB results is the optimum public health strategy for blood banks at the present time.

Fact and fantasy: the roles of accuracy and variability in confusing imaginations with perceptual experiences.

In Experiment 1, pictures were presented to subjects two, five, or eight times, and subjects were asked to imagine each pciture two, five, or eight times. Subsequently, subjects estimated the number of times each picture had been presented. Their estimates of the frequency of these external events were influenced by imagination trials; this effect was greater for good imagers than for poor imagers. Experiment 2 involved a similar design in which subjects were asked either to imagine the same referent for a word or to imagine a different referent for a word on successive imagination trials. Consistency (same referent) did not increase the influence of imaginations on immediate judgments of external frequency. Thus, the results of Experiment 1 were attributed to the greater accuracy (as opposed to greater consistency) of good imagers' internal generations of the stimuli. Furthermore, variation (imagining different referents), like greater accuracy, increased the effects of imagination trials on immediate but not on delayed judgments of frequency. Possible mechanisms underlying these effects are discussed. In general, the two studies show that qualitative characteristics of completely covert generations influence their impact on estimates of the frequency of external events.

Cardio-respiratory changes during pneumoencephalography.

Carbon-respiratory changes associated with changes in posture and injection of intrathecal oxygen were studied in fifeen patients undergoing pneumoencephalography in a Phillips isocentric chair, while breathing spontaneously and anaesthetised with halothane in oxygen. Haemodynamic changes associated with changes in posture were of a minor nature. A rise in PaCO2 occurred in the prone position in two obese patients. There were significant rises in blood pressure following injection of more than 5 ml of oxygen as a bolus into the subarachnoid space.
