Psychopathy is strongly associated with serious criminal behaviour (for example, rape and murder) and recidivism. However, the biological basis of psychopathy remains poorly understood. Earlier studies suggested that dysfunction of the amygdala and/or orbitofrontal cortex (OFC) may underpin psychopathy. Nobody, however, has ever studied the white matter(More)
OBJECTIVE To assess the importance of diabetes, diabetes control, hyperglycemia, and previously undiagnosed diabetes in the development of surgical-site infections (SSIs) among cardiothoracic surgery patients. SETTING A 540-bed tertiary-care university-affiliated hospital. DESIGN Prospective cohort and case-control studies. PATIENTS All patients(More)
We conducted independent case-control and retrospective cohort investigations to assess the relationship between diaphragm use and urinary tract infection (UTI). In the former, we compared diaphragm use and vaginal flora among 114 women with acute UTI and 85 women with acute urinary tract symptoms and no UTI. In the latter study, we ascertained the(More)
Fifty-two cases of toxic-shock syndrome that occurred in January 1, 1976 through August 31, 1980, were reported to the Utah State Health Department between February 1 and August 31, 1980. The annual attack rate for Utah based on a six-month surveillance period was 14.4 per 100,000 women ages 12-49 years. All cases were in women who had onset of illness(More)
Three cases of pubic osteomyelitis in athletes are reported. The clinical presentation in each case was acute groin, hip, or perineal pain; fever; chills; inability to bear weight; and pubic symphysis tenderness. Since radiographic changes in the pubic bone can be delayed, a high index of suspicion is required by the clinician. Although Staphylococcus(More)
beta-Lactamase production and MIC determinations for penicillin, methicillin, and cephalothin were assessed for 67 strains of Staphylococcus saprophyticus and correlated with results of disk diffusion susceptibility testing. Fifty-five (82%) of the 67 strains produced beta-lactamase, and 40 (77%) of these beta-lactamase-producing strains were susceptible(More)
The clinical and epidemiologic characteristics of chronic pulmonary histoplasmosis, as compared with the more familiar acute pulmonary histoplasmosis, are relatively unknown. Opinions vary as to the pathogenesis, and only the severe forms of the disease are readily recognized. Over a 22 month period following the excavation of blackbird roost, an unusual(More)
A 27-year-old man presented with a history of acquired immunodeficiency syndrome and the new onset of weakness and numbness of the lower extremities. During the course of a prolonged and extensive evaluation fraught with iatrogenic complications, it was discovered that his complaints were fabricated and his history of having acquired immunodeficiency(More)
We evaluated and compared 81 urinary tract infections (UTIs) with Staphylococcus saprophyticus occurring in 72 college women with Escherichia coli UTIs. During the 14-month study period, S saprophyticus was the second most common cause of UTIs, accounting for 11% of the total. Staphylococcus saprophyticus infections occurred more frequently during the late(More)
