Predictive power of the polygraph: can the "lie detector" really detect liars?

Expanded use of the polygraph as a detector of lies has been proposed in the United States and the United Kingdom. The positive predictive value of the polygraph (ie, the proportion of positive test results that are true positives) was assessed, on the evidence of the best published data for the sensitivity and specificity of the device. In many screening or investigative situations, the predictive value would be poor; most of the positive results would be false positives. Consequently, truthful persons incriminated as liars by the polygraph would outnumber actual liars with a positive result on the test.

Postpartum acute myocardial infarction: a rare occurrence of uncertain etiology.

Two women who had an acute myocardial infarction during the early postpartum period are described, and the findings in nine other women previously reported on are summarized. Attention is called to the atypical nature of ischemic heart disease and myocardial infarction in these patients when compared with myocardial infarction during pregnancy and with ischemic heart disease in men. Postpartum infarcts most often occur in women in their 20s during their first pregnancy, frequently a pregnancy complicated by the preeclampsia-eclampsia syndrome, and are associated with a high mortality rate. In one of our patients and one patient previously reported on, the results of coronary arteriography were normal, suggesting that coronary arterial thromboembolism or spasm was a cause of the infarction. Because postpartum myocardial infarction may be unrelated to atherosclerotic narrowing, detailed angiographic studies in such patients appear warranted. These cases indicate the variety and complexity of ischemic heart disease in women.

Pseudoephedrine producing postural hypotension in a pilot.

A pilot taking pseudoephedrine (Sudafed) experienced postural hypotension documented as being caused by the drug. This care reemphasizes the potential hazard of self-medication for upper respiratory tract symptoms by flight crew members.
