The effect of providing a USB syllabus on resident reading of landmark articles

Background: The acquisition of new knowledge is a primary goal of residency training. Retrieving and retaining influential primary and secondary medical literature can be challenging for house officers. We set out to investigate the effect of a Universal Serial Bus (USB) drive loaded with landmark scientific articles on housestaff education in a pilot study. Methods: We created a USB syllabus that contains 187 primary scientific research articles. The electronic syllabus had links to the full-text articles and was organized using an html webpage with a table of contents according to medical subspecialties. We performed a prospective cohort study of 53 house officers in the internal medicine residency program who received the USB syllabus. We evaluated the impact of the USB syllabus on resident education with surveys at the beginning and conclusion of the nine-month study period. Results: All 50 respondents (100%) reported to have used the USB syllabus. The self-reported number of original articles read each month was higher at the end of the nine-month study period compared to baseline. Housestaff rated original articles as being a more valuable educational resource after the intervention. Conclusions: An electronic syllabus with landmark scientific articles placed on a USB drive was widely utilized by housestaff, increased the self-reported reading of original scientific articles and seemed to have positively influenced residents’ attitude toward original medical literature

Diagnosis of human immunodeficiency virus type 1 infection in infants by immune complex dissociation p24 assay

Using immune complex dissociation (ICD), we retrospectively examined serum and plasma of 206 infants aged 0 to 4 months who were perinatally exposed to human immunodeficiency virus (HIV). All samples were analyzed in a blinded manner. Infection status was determined based on the results of HIV culture and Centers for Disease Control and Prevention classification. The overall diagnostic sensitivity of the assay was 59% (93 samples, 73 infants), and specificity was 100% (160 samples, 133 infants). When the samples were analyzed according to age, sensitivity was highest at age 1 to 2 months (17 of 21 infants, 81%). Sensitivities at other ages were 53% at &lt; 1 month, 55% at 2 to 3 months, and 48% at 3 to 4 months (9 of 17, 11 of 20, and 12 of 25 cases, respectively). In 11 evaluable cases there was a possible correlation of p24 antigen quantitation (in picograms per milliliter) with disease progression. We conclude that, as determined in this study, the ICD p24 is a rapid diagnostic assay for HIV infection with a sensitivity of &gt;80% at 1 to 2 months of age and 100% specificity, as evaluated, up to 4 months of age.</jats:p

In 11 evaluable cases there was a possible correlation of p24 antigen quantitation (in picograms per milliliter) with disease progression. We conclude that, as determined in this study, the ICD p24 is a rapid diagnostic assay for HIV infection with a sensitivity of >80% at 1 to 2 months of age and 100% specificity, as evaluated, up to 4 months of age
