The emergence of "mad cow disease" has sparked interest in prion diseases, including Creutzfeldt-Jakob disease, a spongiform encephalopathy that can mimic other rapidly progressive dementias. A systematic approach to evaluation and diagnostic testing can help rule out other causes.

This chapter discusses a three‐tiered undergraduate service‐learning program as a collaborative leadership structure, incorporating high‐impact practices.

Clinicians should be aware of the risk of opportunistic infections in patients who are immunocompromised. Opportunistic infections such as Pneumocystis jirovecii commonly are associated with HIV/AIDS, but less commonly considered in patients receiving immunosuppressive and/or immunomodulating therapies. This case report focuses on the management of an opportunistic infection in an HIV-negative patient on immunosuppressive medications for lymphoma and exacerbation of pulmonary fibrosis.
