We retrospectively examined the relationship between fluoroquinolone use and the susceptibilities of 11 bacterial pathogens to fluoroquinolones in 10 US teaching hospitals from 1991 through 2000. Statistical significance was determined by 2-way analysis of variance, with the number of isolates tested each year as a weighting factor. The analysis of baseline-to-end point change in the percentage of susceptibility and the slope of the regression line (trend line) for logit percentage of susceptibility showed that the overall percentage of susceptibility to fluoroquinolones decreased significantly during the study period (P<.05) and that change in percentage of susceptibility was significantly related to change in fluoroquinolone use (P<.05). Particularly notable were the decreases in the susceptibilities of Pseudomonas aeruginosa, Proteus mirabilis, and Escherichia coli (decreases of 25.1%, 11.9%, and 6.8%, respectively).

The Sexual Health Inventory for Men (SHIM) is an effective way to assess erectile difficulty (ED). Despite documented efficacy, however, many physicians may be reluctant to incorporate it into clinical practice because of the intimate nature of the questionnaire. In an attempt to devise and test an easy-to-use computer-based SHIM score indicator for office use, more than 30,000 SHIM questionnaires were administered to men visiting physicians' offices in 2000. Information about age, current smoking status, diabetes, depression, hypertension, prostate disease, and cholesterol levels was also collected. A logistic regression model with a sensitivity of 81.8% and a specificity of 57.7% was created to predict the likelihood of ED in a patient scoring below 21 (SHIM definition). This model was built into a highly graphic Windows-based program. The SHIM score indicator is a convenient way to rapidly identify patients at high risk for ED who should be further assessed.

Human salmonellosis linked to contact with live poultry is an increasing public health concern. In 2012, eight unrelated outbreaks of human salmonellosis linked to live poultry contact resulted in 517 illnesses. In July 2012, PulseNet, a national molecular surveillance network, reported a multistate cluster of a rare strain of Salmonella Braenderup infections which we investigated. We defined a case as infection with the outbreak strain, determined by pulsed-field gel electrophoresis, with illness onset from 25 July 2012-27 February 2013. Ill persons and mail-order hatchery (MOH) owners were interviewed using standardized questionnaires. Traceback and environmental investigations were conducted. We identified 48 cases in 24 states. Twenty-six (81%) of 32 ill persons reported live poultry contact in the week before illness; case-patients named 12 different MOHs from eight states. The investigation identified hatchery D as the ultimate poultry source. Sampling at hatchery D yielded the outbreak strain. Hatchery D improved sanitation procedures and pest control; subsequent sampling failed to yield Salmonella. This outbreak highlights the interconnectedness of humans, animals, and the environment and the importance of industry knowledge and involvement in solving complex outbreaks. Preventing these infections requires a 'One Health' approach that leverages expertise in human, animal, and environmental health.
