54. Top Consults: Solitary Pulmonary Nodule

Posted on September 26, 2023 by Pulm PEEPs

We are thrilled to be back with another episode in our Top Consults series. We are talking about Solitary Pulmonary Nodules, which is something every pulmonologist will encounter in the clinic and on in-patient consults. We go through a number of cases and provide a framework for approaching these cases.

Meet our guests

Dr. Jessica Wang Memoli is board certified in pulmonary disease, critical care medicine and internal medicine. She is the Director of Bronchoscopy and Interventional Pulmonary, as well as the Associate Fellowship Program Director for Pulmonary Critical Care Medicine at the MedStar Washington Hospital Center. Dr. Wang Memoli received her medical degree from the University of Miami Miller School of Medicine. She completed her residency at MedStar Washington Hospital Center and her fellowship training at the Medical University of South Carolina in Charleston.

Dr. Nick Ghionni works at Union Memorial, Good Samaritan, and Franklin Square as an Intensivist and Pulmonologist. He completed his Internal Medicine residency at Mercy Catholic Medical Center in PA serving as Chief Internal Medicine resident. He was a fellow at MedStar Washington Hospital Center where he was the Chief Pulmonary Critical Care Fellow. His specific interests include mechanical ventilation, POCUS, and medical education.

Case Presentations

Case 1:

33 year old woman who came to the emergency department with acute onset of shortness of breath. She states that she had been in her normal state of health until this morning when she developed shortness of breath at rest, and chest pain. She does report a non-productive cough over the last few weeks which she feels may be contributing to her chest pain. She does report a history of asthma during childhood but without any exacerbations or maintenance therapies needed during her adulthood. She does report wheezing when she is sick with a cold but this is infrequent. The ED team sent off an initial work-up including a D-Dimer which was elevated, and she underwent a CTA of the chest for concern for possible PE. On the CT scan, there was no PE but the radiologist did call a “2 mm indeterminate right upper lobe pulmonary nodule.”

Case 2:

We have a 67-year-old male with a past medical history of ischemic cardiomyopathy, chronic systolic heart failure (LVEF 10-15%), s/p AICD, diabetes mellitus type 2, hyperlipidemia, hypertension, chronic kidney disease stage III, prostate cancer s/p seed implantation that was over 15 years ago who presented with acute decompensation of his heart failure and cardiogenic shock. He was successfully managed for that and is now being worked up by advanced HF and as a part of that workup got a chest CT, which found a RUL 6 mm nodule.

Case 3:

We have a 66-year-old male with a past medical history of HTN and drug abuse who presented to the ED with acute SOB, likely a COPD exacerbation. He was given bronchodilator and steroids as well as being started on Bipap. He eventually was able to be weaned off Bipap and was able to tolerate nasal cannula. As a part of his initial work up, the patient underwent CT scan for possible PE which demonstrated a new LUL spiculated nodule that is 1.3cm that is new since 2019.

Key Learning Points

Approaching Pulmonary Nodules:

A structured approach is essential due to the complexities of diagnosing pulmonary nodules.
Patient history, including risk factors, past interventions, and imaging, plays a vital role.
Nodules’ appearance, such as location, shape, or characteristics like calcification or spiculation, can provide diagnostic clues.
The nodules history on serial imaging is a key predictive risk factor for determining the likelihood that the nodule represents cancer
Tools like the Mayo Risk Calculator and Fleishner Society guidelines assist in risk assessment and guidance.
It’s essential to assess patient risk, and nodule risk, and prioritize patient concerns and education. Periodic monitoring or follow-up might be necessary based on the nodule’s risk and size.
A multidisciplinary approach involving various specialists ensures comprehensive care.

Key Discussion Points:

PET Scans:

Useful in gauging a nodule or tumor’s metabolic activity.
Large, hypermetabolic nodules are suspicious.
Not every positive PET result means malignancy; other causes like inflammation or scars can produce positive results.

Evaluating Nodules:

Consideration of nodule size, characteristics, patient history, and risk calculators is crucial.
Tumor boards provide a collaborative expertise approach.

Tissue Sampling & Testing:

The method of tissue sampling depends on resources and expertise.
CT-guided biopsy offers a high diagnostic yield but with a risk of pneumothorax.
Bronchoscopic biopsy provides a lower diagnostic yield than CT-guided biopsy but has a significantly reduced risk of complications.
Advanced diseases now often require molecular testing on tissue samples.

Ground Glass Nodules:

Different from solid nodules due to their slow growth rate.
Monitoring is crucial due to the potential for transformations raising cancer suspicions.
The approach for ground glass nodules typically involves more extended monitoring intervals than for solid nodules.

Holistic Evaluation:

Consider the nodule’s characteristics, the patient’s history, and clinical intuition.
Individualized patient assessment is as vital as evidence-based guidelines and clinical expertise.

Consult Patient

Ms. Pamela Harris (PH) is a 47-year-old woman with PMH of migraines, obesity s/p gastric sleeve (BMI now 33), and a history of remote DVT in her 20s while on OCP s/p 6 months of AC who is referred to pulmonary hypertension clinic for evaluation of dyspnea on exertion. She has actually had dyspnea for some time and previously it has been attributed to her weight. Based on this, she pursued a gastric sleeve and has lost 55 pounds, but continues to have shortness of breath. She has no cough, and does not get dyspnea at rest, but notes that after 1 flight of stairs, or 2-3 blocks on flat ground she has shortness of breath. She saw her PCP and had basic labs, basic spirometry, and an echocardiogram. He did not note anything significant on examination in the notes.

The labs had no anemia, and normal renal and liver function. Her serum bicarbonate was 25 and there was no blood gas. Spirometry showed an FVC 82% predicted, FEV1 83% predicted, and FEV1/FVC was 99% predicted. The echocardiogram had normal LVEF, mild LVH, normal RV size and function qualitatively. There was mild TR with tricuspid valve peak regurgitant velocity of 3.4 m/sec. The estimated PASP + RA pressure (based on normal IVC diameter 2.1 cm) was 46 mmHg.

RHC: Systemic BPs 140s/90s, with O2 saturations 97-98% on RA throughout. RA mean pressure was 9, RV was 48 with an RVEDP of 17, PA was 48/27 with mean of 34, and PCWP mean was 11. CO/CI by Fick was 5.56 / 2.42, and by thermo was similar, 5.8 / 2.52. Her PA sat was 62%, and PVR was 3.97 WU.

17. Top Consults: Pneumothorax

Posted on May 24, 2022 by Pulm PEEPs

This week on Pulm PEEPs we are resuming our Top Consults series with a common pulmonary presentation that can range from incidental to life-threatening: pneumothorax. We will talk through three different cases and review assessments and common management strategies. Make sure to subscribe to our show wherever you listen to podcasts, rate and review us, and visit our website to catch up on all our old content.

Meet Our Guests

Christine Argento is an Associate Professor of Medicine at Johns Hopkins Hospital and specializes in Interventional Pulmonology.

Charlie Murphy received his medical degree from LSU School of Medicine in New Orleans and completed his internal medicine residency at the Montefiore-Einstein Internal Medicine Residency Program. He is currently a Pulmonary and Critical Care fellow at New York-Presbyterian Hospital / Columbia University Medical Center, where he is one of the chief fellows.

Consult Patients

Barry is a 26-year-old man who came to the emergency department with acute onset of shortness of breath. He is tachypneic to 26, saturating 88% on RA so he was put on NC and is now 95% at 4L, HR 120, BP 145/85. There is only limited history but he reports he has never had anything like this before. His CXR shows a pneumothorax 5cm from the apex.

Larry is a 22-year-old man with normal HR and BP, saturating 96% on RA and breathing 14 x a minute. He has a CXR that shows a small pneumothorax. He has no past medical history and has never had a pneumothorax before, but he is a 1 PPD smoker and smokes marijuana.

Carrie is a 54-year-old woman who has been admitted with a COPD exacerbation. She has a history of emphysema, is not on home oxygen, and came in 2 days ago with worsening dyspnea and increased productive cough. She has been being treated with nebulizers every 4 hours, azithromycin, steroids, and supplemental O2 at 2L NC/ minute and never required NIPPV. This morning she had a coughing spell and significant chest pain and a CXR shows a moderate-sized left-sided pneumothorax. She is on 10L NC now with tachypnea to 26, and HR 105 but stable blood pressure.

Key Learning Points

Management options for a persistent air leak

— Conservative management: continue chest tube to suction

— Heimlich valve – can discharge a patient with this valve if they are stable to water seal, but don’t tolerate clamping

— Blood patch – inject the patient’s own blood into the chest tube to try to heal any pleural defect

— Chemical pleurodesis – inject talc powder, doxycycline, or another substance through the chest tube to cause pleural irritation and closure of the pleural space

— Endobronchial valve – off-label use

— VATS – surgical pleurodesis, resection of blebs

9. Top Consults: Interstitial Lung Disease Diagnosis

Posted on February 15, 2022 by Pulm PEEPs

This week we are absolutely thrilled to be joined by three Interstitial Lung Disease experts to discuss the workup and differential for a patient with a new presentation of suspected ILD. This is also our first episode in a collaboration between the Pulm PEEPs and the American Thoracic Society Clinical Problems Assembly. In a series of episodes, we will be joined by pulmonary experts from around the country who are leaders in the ATS CP Assembly to provide content on common and cutting-edge topics in PCCM.

Meet Our Guests

Sonye Danoff is an Associate Professor of Medicine at Johns Hopkins and is Co-Director of the John Hopkins Interstitial Lung Disease and Pulmonary Fibrosis program. She also serves as the Assembly Chair of the Clinical Problems Assembly for the American Thoracic Society.

John Kim is an Assistant Professor of Medicine at UVA and has both clinical and research expertise in interstitial lung disease with a focus on pulmonary fibrosis.

Shweta Sood is an Assistant Professor of Medicine at Penn Medicine whose expertise is in Interstitial Lung Disease. She is an integral part of fellowship training where she leads the monthly ILD conference for fellows as well as provides didactics for ILD cases.

Consult Patient

A 66-year-old man who is a never smoker with a past medical history of hypertension and osteoarthritis was admitted to the hospital after presenting with progressive dyspnea on exertion to dyspnea at rest and was found to be hypoxemic. He reports 4 months of progressive dyspnea on exertion but on further questioning, thinks he was last normal about 1.5 years ago when he could walk 2 miles at a time. Currently, he can only walk 0.25 to 0.5 miles before needing to stop. He reports an intermittent, dry cough throughout the day that is not associated with eating, position, or sleeping. A full ROS is negative including for rashes or joint pains. His family history is notable only for hypertension and hyperlipidemia. He is a never smoker, drinks in moderation 1-2 x a week, and lives in the suburbs with his wife. His house has central heating and air conditioning, they have no pets, and they have carpeted floors. He is a retired police detective.

His physical exam is notable for fine crackles at the bilateral bases on pulmonary auscultation, and he is breathing comfortably on nasal cannula although mildly tachypneic to 18 breaths per minute. He has no signs of volume overload, no peripheral clubbing, no rashes, and joint exam does not reveal swelling or synovitis.

Key Learning Points

Take away points from our guests:

— ILD is a symptom, not a diagnosis

— The first time a patient is evaluated for interstitial lung disease is the best chance for making the diagnosis so take the time to evaluate them thoughtfully

— Start the physical exam with the hands first. The hands can reveal a lot about the patient (clubbing, cyanosis, joint, skin, and nailbed findings) and it establishes a personal connection

— When doing the pulmonary exam, percuss first from top to bottom to learn the size of the lungs, and then listen from bottom to top

— When reading a CT scan the simplest approach is “Is it a UIP pattern or not?”. This can be your first diagnostic divide. UIP is consistent with IPF, and in select circumstances connective tissue disease, occupational lung disease, or advanced hypersensitivity pneumonitis. Non-UIP patterns have a broader differential

— A multi-disciplinary interstitial lung disease conference is the gold standard for establishing an ILD diagnosis

Gathering the history:

— Ask about onset: acute or chronic. “When was the last time your breathing was entirely normal?”

— Symptoms can be shortness of breath, a lingering cough, or often fatigue and decreased energy. Occurrence is important! Do symptoms occur only with exertion or at rest too?

— “Have you ever had chest imaging before?”

— Take a thorough exposure history, and the weird questions are all necessary! Ask about birds and feathers (pet birds, bird feeders, down pillows or blankets, hunting, taxidermy), mold or water damage, organic or inorganic compounds from work (landscaping, ship yards, coal mines)

American College of Chest Physicians – Interstitial Lung Disease Patient Questionnaire

Physical Exam:

— Assess stability first and foremost

— Lung findings: crackles, inspiratory squeaks (often in hypersensitivity pneumonitis)

— Look for evidence of alternative diagnoses: volume overload, liver disease, signs of infection

— Evaluate for signs of connective tissue disease: examine the skin around the forehead and mouth for signs of scleroderma, look for rashes, perform a thorough joint examination and look at their hands, and assess muscle strength

Imaging:

— Order a high-resolution CT scan without contrast. High resolution means thin slices that are 1-2 mm thick. Contrast should be avoided if possible because it makes looking for subtle reticulations or ground-glass opacities harder

— Inspiratory and expiratory films help evaluate for gas trapping. If present, this may indicate hypersensitivity pneumonitis

— Prone films allow you to distinguish reticular changes in the dependent portions of the lungs from atelectasis

Reading the CT scan:

— Look at the distribution first. Is it uniform from top to bottom or not? Is it subpleural, peripheral predominant, or central?

— Identify key features: reticulation, traction bronchiectasis, honeycombing, ground-glass opacities, cysts, and nodules

Laboratory evaluation:

— ANA, Scl-70, DS DNA, anti-RNP, anti-centromere, RF, CCP, SSA, SSB, RNA pol 3, HIV, myositis panel, Hypersensitivity pneumonitis panel

Pulmonary function tests:

— A restrictive ventialtory defect is the classic pattern and can tell you about severity. In ILD, TLC, VC, FRC, and RV are generally all reduced in proportion

— Identify if there is obstruction or not, because if present this may indicate coexisting emphysema or hypersensitivity pneumonitis

–The DLCO can be helpful for disease severity, and for raising concern about other co-existing diagnoses such as pulmonary vascular disease, or emphysema

— A DLCO < 50% predicted may predict that the patient will need oxygen with exertion and the patient should be walked

6 Minute Walk Test:

— This should be performed for all new patients because it is important for prognosis

— In the first year after diagnosis, a 6MWD should be performed every 3 – 4 months to assess disease trajectory. It can be done every 6 – 12 months after that.

Differential Diagnosis:

Silo ILDs into two large buckets

1) An exposure, trigger, or underlying cause is present: hypersensitivity pneumonitis, medication-induced, occupational lung disease, connective tissue disease, granulomatous disorder

2) Idiopathic interstitial pneumonia

4. Top Consults: Hemoptysis

Posted on December 7, 2021 by Pulm PEEPs

Pulm PEEPs hosts, Kristina Montemayor and David Furfaro, bring our first episode in our Top Consults series. In this series, we will bring in experts to work through the most common pulmonary and critical care consults. Whether you are the consulting physician, or a pulmonologist responding to the page, these episodes are geared to give you all the information you need to care for your patients!

Today, we are joined by Chris Kapp and Matthew Schimmel, two interventional pulmonologists, to discuss hemoptysis. Chris and Matt will help us work through two hemoptysis consults, and together we’ll provide a framework for thinking about hemoptysis, outline some key components of the evaluation, and delve into treatment options.

Key Learning Points

Hemoptysis Evaluation

Hemoptysis Management

Life-Threatening or Large Volume Hemoptysis

Stabilize the patient! Make sure the airway is protected either by the patient coughing themselves, or intubation if needed. Provide hemodynamic support with IVF, blood products, and pressors if needed. If it is known which lung has the bleeding the patient can be positioned so the lung with the bleeding is down. This protects the non-bleeding lung.
Correct any bleeding diathesis If the patient is on anti-coagulation, or has any reversible bleeding diathesis, these should be corrected immediately to reduce further bleeding.
Localize the bleed If the patient is stable, they should undergo a CTA to localize the bleeding. If they are not stable to make it to a CT scan, a bronchoscopy should be performed.
Bronchoscopic treatment In addition to clearing blood from the airway, bronchoscopy can localize the bleeding. With available expertise, bronchoscopic treatments can be performed such as ice saline, topical epinephrine, or balloon tamponade to isolate the bleed.
Definitive therapy with arteriography and embolization Patients with life-threatening hemoptysis should ultimately undergo arteriography and embolization of any bleeding vessel. If this is not possible, then surgery can be needed in some cases.
A note on diffuse hemoptysis If there is not one distinct bleeding lesion, then localizing and treating the bleed becomes more difficult. For diffuse alveolar hemorrhage, evaluation should be performed for if it is primary, and due to an immunologic cause and capillaritis, or secondary to a systemic disease and / or bleeding diathesis. These investigations will guide available treatment options. Capillaritis from an immunologic cause, such as lupus or vasculitis, can be treated with systemic glucocorticoids and an additional immunosuppressive agent such as cyclophosphamide or rituximab.

Non-life-threatening or Small Volume Hemoptysis

Monitor for clinical worsening Patient’s should be monitored, either in the in-patient or out-patient setting, for increased volume or frequency of hemoptysis and for any clinical worsening, such as desaturations or decreased ability to clear the airway.
Correct any bleeding diathesis If the patient is on anti-coagulation, or has any reversible bleeding diathesis, these should be corrected immediately to reduce further bleeding. In pattients with non-life-threateneing hemoptysis this requires careful consideration of balancing the risk of bleeding vs the benefits for continuing anti-coagulation.
Evaluate for underlying cause Patient’s should undergo imaging and evaluation for the underlying cause of the hemoptysis. This may be evidence of an underlying infection, a pulmonary embolism, or new lung lesions making the patient at risk. If the source can’t be found on non-invasive imaging, and there is no clear systemic source such as an infection, a bronchoscopy is warranted. Any underlying cause should be treated and investigated further.
Inhaled Tranexamic Acid Nebulized tranexamic acid is well tolerated and can help resolve hemopytysis without invasive procedures.
