ABSTRACT
Pathology is not traditionally chosen by medical students applying to residency. In osteopathic medical schools, limited access to dedicated pathology faculty further complicates this issue. Because of a lack of pathology experiences, osteopathic medical students may not be as familiar with a pathology career. The purpose of this brief report is to describe the pilot experience of implementing a pre-existing web-based, free virtual platform for pathology education as alternative, supplemental exposure to pathology for osteopathic medical students at our institution. We began to offer the online pathology elective for Academic Year 2022-2023. Using the online free service of PathElective, this course provided a valuable exposure to pathology with multiple modules in anatomic, clinical, and digital/molecular pathology, before and after assessments, recorded videos by pathology experts, handouts, and reading assignments. During the first week, three introductory modules were required followed by weeks 2-4, in which the students would complete a total of 10 modules of their own choice. In total, 14 students participated in this virtual rotation from August 2022-May 2023. All chose cardiac pathology as the most popular module. Three of the 14 students matched into pathology residencies. This small cohort of 4th year medical students at our osteopathic medical school successfully completed a virtual elective rotation with the resources of PathElective. We report the success of this experience and hope to continue monitoring progress.
ABSTRACT
Marantic endocarditis (ME) is defined by noninfectious valvular vegetations. The most common disorders associated with ME are malignancy with or without hypercoagulable state, intercardiac instrumentation, residual vegetations from previously treated infective endocarditis (IE), renal insufficiency, and burns. Another important cause of ME is systemic lupus erythematosus when accompanied by vegetations, that is, Libman-Sacks endocarditis. ME should be differentiated from IE because they may present with similar clinical features. Both ME and IE may present with fever and a heart murmur with or without embolic phenomenon. Leukocytosis and elevated erythrocyte sedimentation rate suggest the diagnosis of IE. The hallmark of IE is a cardiac vegetation and continuous high-grade bacteremia. After exclusion of the causes of culture negative endocarditis, the absence of bacteremia clearly differentiates ME from IE. We present a case of ME mimicking acute bacterial endocarditis (ABE). The differential diagnostic features of ME versus IE are discussed. To the best of our knowledge, this is the first reported case of quadrivalvular ME with massive vegetations on all cardiac valves, as well as the aorta, atria, and pulmonary artery.
