The Sixth Extinction: Infectious Diseases Implications

By John Toney, MD, FIDSA

October 24th, 2017

Dr. Toney discusses the phenomenon of mass extinctions occuring over the history of life on our planet, and how it is believed we are currently in the sixth worldwide extinction. He speculates on its relevance in the context of human pathogens such as Clostridium difficile, multidrug resistant gram negative enteric bacteria, and on the persistance of gut microbiota. He closes by discussing potential future therapies for human diseases given the waning antimicrobial agent options we currently have to treat them.

Infectious Diseases Discoveries of Historical Importance

By Adam Pettigrew, MD

October 3rd, 2017

Dr. Adam Pettigrew takes us on a journey through the history of infectious diseases discovery.  Starting off in ancient Greece, he then catapults forward into the renaissance and then on to the 19th and 20th centuries  to understand where the modern practice of infectious diseases originated.

Climate Change and Infectious Diseases: A Decade Later

By Manuel Castro, MD

September 1st, 2017

Dr. Manuel Castro presents an update on the effects that climate change is having on infectious diseases as we approach the end of the second decade of the new millennium.  He covers the impact that a warming climate is having on ecosystems that breed infectious pathogens as well as the vectors that carry them.

Neutropenic Fever in the 21st Century

By Rod Quilitz, Pharm.D., BCOP

August 1st, 2017

Dr. Quilitz discusses the risk factors behind neutropenic fever. He then discusses prominent bacterial, fungal, and viral pathogens which cause infections in the immunocompromised cancer patient.

Pneumonia Patterns

By John Greene, MD

July 21st, 2017

Dr. John Greene discusses different patterns of consolidation visible on lung imaging and the differential diagnosis for pneumonia in immunocompetent and immunocompromised patients. He reviews CT imaging for ground glass opacities, consolidation, nodular opacities, and nodular cavitary lesions on the lungs. He covers interstitial pulmonary fibrosis, pulmonary alveolar proteinosis, community acquired viral and bacterial pneumonia, fungal infections, and mycobacterial infections among others. He specifically discusses nocardia, mycobacterium avium complex and hypersensitivity pneumonitis. He then covers several cases studies and management strategies. His updated talk was originally presented in 2013.

Bugs, Drugs, and Stem Cells

By Aliyah Baluch, MD, Msc

July 17th, 2017

Dr. Baluch introduces the audience to to concept of hematopoietic stem cell transplantation.  She discusses the timeline for infections and the tools for their work-up, including antimicrobial drugs.  She also reviews the current paradigm for the work-up of neutropenic fever, and the treatment of “common” ID issues.  Lastly, she discusses useful infectious diseases resources for the clinician.

Infectious Diseases Emergencies

By Misbuhuddin Syed, M.D.

July 10th, 2017

Dr. Syed discusses various infectious diseases syndromes that are “emergencies,” i.e., require urgent intervention.  Among those discussed include fulminant meningococcal disease, viral hemorrhagic fever, SARS, MERS, Anthrax, Plague, Tularemia, and other agents of bioterroism.
