10. A Case of Fevers, Night Sweats, and Dyspnea

Posted on by

This week, we have another great case episode on Pulm PEEPs! We are joined by Emily Fridenmaker who helps us think through a fascinating case presenation.

Meet Our Guests

Emily Fridenmaker is a Pulmonary, Critical Care, and Sleep Medicine fellow at the University of Kentucky College of Medicine. She went to medical school at West Virginia school of medicine and did her internal medicine residency at Charleston Area Medical Center

Patient Presentation

A middle-aged woman presents with 2-3 weeks of mild but progressive shortness of breath with exertion associated with low-grade fevers, worsening night sweats, and fatigue. Further history reveals a progressive non-productive cough and weight loss. She has a past medical history of neurologic dysfunction over two years and a working diagnosis of chronic inflammatory demyelinating polyneuropathy and is pursuing treatment in Mexico due to cost limitations. She has been receiving prednisone 10 mg daily and azathioprine. Aside from travel history to Mexico, her social history is notable for prior employment in a candle factory, and for hiking with some cave exploration. She is a former 20 pack-year smoker and has rare alcohol use.

Radiology Rounds – 2/22/22

Posted on by

This week we’re sharing a distinct radiology pattern on chest X-ray and CT scans that should raise its own differential. Make sure to listen to our case episode next week to hear more about this patient and the diagnostic workup.

3. A Case of Worsening Episodic Dyspnea

Posted on by

The Pulm PEEPs are excited to bring our first mystery case! Kristina Montemayor and Dave Furfaro hear a fascinating case presentation from Pulm PEEPs senior editor Ansa Razzaq. Join us as we work through this case together to come to a diagnosis, and share our thought process along the way. Come back to these show notes afterward, or once you’ve solved the case yourself, for some key teaching pearls and representative images.

Patient Presentation

A 66-year-old woman with no smoking history and past medical history of previously well-controlled asthma is referred to pulmonary clinic after multiple recent episodes of dyspnea, wheezing, and coughing. The episodes have features consistent with asthma exacerbations; however, they are also associated with migratory infiltrates. She has been treated with multiple courses of antibiotics and steroids, and despite escalating therapy, the episodes are occurring more frequently and she was worsening overall exercise tolerance. Listen in to hear more and try to solve the case!
