34. Fellows’ Case Files: The Ohio State University College of Medicine

Posted on February 7, 2023 by Pulm PEEPs

Welcome back to Pulm PEEPs Fellows’ Case Files series. We are traveling to the midwest to visit The Ohio State University College of Medicine and hear about another great pulmonary case.

Meet Our Guests

Kashi Goyal is a second-year Pulmonary and Critical Care Fellow at The Ohio State University Wexner Medical Center. She obtained her MD at OSU, and then completed her Internal Medicine residency at Beth Israel Deaconess Medical Center. She worked as a hospitalist and educator before going back to fellowship and remains passionate about medical education.

Lynn Fussner is an Associate Professor of Internal Medicine at OSU and has been there since completing her fellowship and Post-doctorate at Mayo Clinic. In addition to her clinical work in the multidisciplinary vasculitis clinic, she is a translational researcher with a focus on inflammatory pulmonary disorders and vasculitis.

Avi Cooper is an Assistant Professor of Medicine at Ohio State University College of Medicine and the Program Director of the Pulmonary and Critical Care Fellowship. He is an Associate Editor at the Journal of Graduate Medical Education. Last but not least, he co-hosts the Curious Clinician Podcast, one of the most popular medical education podcasts.

Key Learning Points

**Spoilers Ahead** If you want to think through the case on your own we advise listening to the episode first before looking at these points.

The three most common causes of cough in adults in the USA are cough variant asthma, GERD, and post-nasal drip
A post-viral cough can last for 8-12 weeks and still be within normal
Sinus symptoms in a chronic cough can just be sinusitis and post-nasal drip, but should consider eosinophilic granulomatosis with polyangiitis (EGPA), aspirin exacerbated respiratory disease (AERD), cystic fibrosis, or ciliary dyskinesia.
Examination of a wheeze
- Fixed sound vs variable
- Pitch: larger central airways vs lower peripheral airways
- Is it throughout the cycle or at a certain phase?
- Ask the patient to cough before listening and ask them to breathe out through their mouth
Approach to eosinophilia in a patient with cough and dyspnea
- Multi-system involvement vs lungs
  - Multi-system involvement
    - Vasculitis
    - Parasitic infection
    - Hematologic malignancy
    - Medication side effect
    - Primary hypereosinophilic syndromes
  - Within the lungs:
    - Parenchymal disease
      - Loeffler’s syndrome
      - Eosinophilic pneumonia
    - Airway disease
      - Asthma
      - ABPA
If you have a high suspicion for airways disease, PFTs should be requested with bronchodilator testing regardless of the degree of obstruction on baseline spirometry
Asthma alone should not cause ground glass opacities, so if see these in a patient with asthma we think about:
- Infection, especially atypical infections
- EGPA
- Vasculitis with DAH
- ABPA
- Hypogammaglobulinemia or other immunodeficiency
EGPA diagnosis
- ANCA testing is only positive in 60% of patients with EGPA so a negative test doesn’t rule it out by any means
- It is easiest to make a diagnosis when there is a clear small vessel manifestation
  - Alveolar hemorrhage
  - Mononeuritis multiplex
  - Glomerulonephritis
- Many patients with asthma, nasal polyposis, and high peripheral eosinophilia have EGPA but don’t have a clear small vessel feature of vasculitis or a positive ANCA
  - These patients typically have eosiniophilia a lot higher than when thinking about allergic phenotype asthma alone. As a rule of thumb, at least an absolute eosinophil count > 1000

7. Top Consults: Severe Asthma Exacerbation

Posted on January 18, 2022 by Pulm PEEPs

We are excited to bring you another episode in our Pulm PEEPs Top Consults series! Kristina Montemayor and David Furfaro, are joined by Sandy Zaeh to discuss the assessment and management of a patient with a severe asthma exacerbation. We’ll follow a consult patient from the emergency department to the ICU, and cover everything from the physiology of pulsus paradoxus in asthma to how to manage the ventilator in status asthmaticus. Listen today and please send any questions our way on Twitter @pulmPEEPS.

Meet Our Guests

Sandy Zaeh is an Instructor of Medicine and Pulmonary & Critical Care Medicine physician at Yale School of Medicine.

3. A Case of Worsening Episodic Dyspnea

Posted on November 23, 2021 by Pulm PEEPs

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!
