A 50-year-old man presented to the hospital for workup of a symptomatic inguinal hernia. At presurgical workup, findings from a contrast material-enhanced CT of the chest, abdomen, and pelvis revealed a large, well-defined and enhancing middle mediastinal mass arising from the right ventricular outflow tract. The mass was ultimately deemed resectable due to preserved fat planes between the mass and other mediastinal structures and the preservation of the right and left coronary arteries. The tumor was diagnosed as a mediastinal paraganglioma at histologic assessment. Keywords: Adults, Angiography, CT-Angiography, MR-Angiography, Cardiac, Neoplasms-Primary ©RSNA, 2021.
ABSTRACT
BACKGROUND: A new course was offered to introduce basic global health concepts to all first year Johns Hopkins medical students, that took advantage of new distance learning capacity to connect medical students in Baltimore with students and faculty in Uganda, Ethiopia, Pakistan and India. AIMS: Lessons learned from the launch of this new course will optimize the conduct of future global health courses at JHUSOM and may be of value to other institutions. METHODS: Feedback from the Hopkins students was obtained through an on-line structured course evaluation questionnaire. Unstructured student and faculty feedback from partners institutions was solicited via email. RESULTS: Students reported high levels of satisfaction with the course content and format, as well as achievement of course competencies and objectives. CONCLUSIONS: Distance learning can support unique, high-quality medical educational experiences that leverage technology and global connectivity, but also the power of group learning and "South-to-North" capacity building.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) colonization is a predictor of subsequent infection in hospitalized adults. The risk of subsequent MRSA infections in hospitalized children colonized with MRSA is unknown. METHODS: Children admitted to an academic medical center's pediatric intensive care unit between March 2007 and March 2010 were included in the study. Anterior naris swabs were cultured to identify children with MRSA colonization at admission. Laboratory databases were queried and National Healthcare Safety Network definitions applied to identify patients with MRSA infections during their hospitalization or after discharge. RESULTS: The MRSA admission prevalence among 3140 children was 4.9%. Overall, 56 children (1.8%) developed an MRSA infection, including 13 (8.5%) colonized on admission and 43 (1.4%) not colonized on admission (relative risk [RR], 5.9; 95% confidence interval [CI], 3.4-10.1). Of those, 10 children (0.3%) developed an MRSA infection during their hospitalization, including 3 of 153 children (1.9%) colonized on admission and 7 of 2987 children (0.2%) not colonized on admission (RR, 8.4; 95% CI, 2.7-25.8). African-Americans and those with public health insurance were more likely to get a subsequent infection (P < .01 and P = .03, respectively). We found that 15 children acquired MRSA colonization in the pediatric intensive care unit, and 7 (47%) developed a subsequent MRSA infection. CONCLUSIONS: MRSA colonization is a risk factor for subsequent MRSA infection in children. Although MRSA colonized children may have lower risks of subsequent infection than adults, children who acquire MRSA in the hospital have similarly high rates of infection. Preventing transmission of MRSA in hospitalized children should remain a priority.
