Q: Abstract: Using neuropsychological testing procedures, we measured the behavioral characteristics of patients with epilepsy unaffected by anticonvulsant drugs and compared these results with control subjects matched for age, sex, and education. In a nationwide VA Cooperative study, 622 patients with well-defined seizure types were given a selected battery of neuropsychological tests prior to and at 1 month after initiation of drug therapy. Seventy-four control subjects were administered the same test battery under standardized conditions at the same VA testing centers. All tests of controls were also repeated 1 month later. The patients with epilepsy scored significantly and consistently below the level of the control subjects on all but three behavioral measures. Differences reaching statistical significance were found on tests of motor function (Finger Tapping, Pegboard, Color Naming), cognitive-attention (Digit Symbol, Discriminative Reaction Time, Word Fluency), and subtests of the Profile of Mood Status (tension, depression, vigor, and confusion). These data provide a profile of behavioral characteristics of unmedicated patients with epilepsy.

Q: Abstract: To determine the timing of symptoms and oocyst excretion after the acquisition of cryptosporidium infection, we used a screening parasitologic stool examination to identify patients and then contacted them for the collection of retrospective histories and follow-up stool specimens. The study included 68 otherwise healthy patients with an identifiable source and time of infection. All 68 had diarrhea, 61 had abdominal pain, most also had other gastrointestinal symptoms, 33 had fever, and all recovered spontaneously. Among the 50 patients who submitted follow-up stool samples, more than 90 percent of the 610 symptomatic days and of the 136 oocyst-positive stools occurred between days 7 and 28 of infection, the mean incubation period was 7.2 days (range, 1 to 12), and the mean duration of illness was 12.2 days (range, 2 to 26). During the oocyst-excretion period cryptosporidium was detected in 90 percent of Ziehl-Neelsen-stained fecal concentrates. The end of oocyst excretion could be accurately determined in 26 patients; 19 (73 percent) had positive stools after the cessation of symptoms for a mean period of 6.9 days (range, 1 to 15). Fourteen patients were studied for two or more months, and in three of them asymptomatic episodes of oocyst excretion were detected up to two months after clinical recovery. We conclude that many cases of symptomatic cryptosporidiosis occur among immunocompetent patients, some of whom may excrete oocysts even when they have become asymptomatic. Conversely, infected symptomatic patients may occasionally have intermittently negative stools.

Q: Abstract: To study patient preferences on physician attire and etiquette, we interviewed 200 patients on the general medical services of teaching hospitals in Boston and San Francisco. Of these 200 patients, 65% believed physicians should wear a white coat, 27% believed physicians should not wear tennis shoes, 52% believed physicians should not wear blue jeans, 37% believed male physicians should wear neckties, and 34% believed female physicians should wear dresses or skirts. Forty percent of patients wanted physicians to address them by first name, but only 10% of patients wanted to address their physicians by first name. A concurrent mailed survey of 74 medical house staff members at the two hospitals revealed wide variability in physicians' attire and in how patients were addressed at each institution. Thus, many house officers had habits that were less formal than a substantial portion of their patients preferred.
