Patient Presentation
A 26-year-old man presents to his primary care doctor with 1.5 months of intermittent dyspnea, cough, chest tightness, and fatigue. His dyspnea was initially exertional, and he noticed he could do less at the gym. However, in the past 3-4 weeks it has progressed to being even with mild movement. His brother was recently diagnosed and treated for acute bronchitis so he thought this could be similar. In the office, he is noted to be tachypneic with an oxygen saturation of 83% breathing ambient air. A chest X-ray is obtained and he is sent urgently to the emergency department.

Crazy Paving is a radiological term describing ground glass opacities with superimposed interlobular septal thickening. The differential diagnosis is broad and includes infectious, neoplastic, and autoimmune processes. It is not limited to just Pulmonary alveolar proteinosis (PAP) but is suggestive in an appropriate clinical setting.
PAP is a disorder of surfactant production or clearance and its etiology is divided into three major subgroups. Primary or autoimmune; Secondary such as from toxic inhalations, hematological disorders, or medications; and Congenital
PAP is diagnosed by positive Periodic acid-Schiff (PAS) staining of lipo-proteinaceous material in the distal bronchioles and alveoli on lung biopsy. The diagnosis can be made with PAS-positive BAL staining, but this has limited sensitivity and lung biopsy is necessary for the diagnosis in up to 30 – 35% of cases.
It is important not to anchor on a diagnosis when a patient presents to you for re-evaluation even if seen by a prior expert. This was pivotal in this case!
Please don’t put anything in your lung. Any toxic inhalation exposure could result in significant damage to lung parenchyma and morbidity as a result.
Today on Pulm PEEPs, we are joined by two pioneers in the field of post-intensive care outcomes and delirium research. Drs.

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.

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
We are thrilled here at Pulm PEEPs to have our first episode with our new Associate Editor Tess Litchman.

Patient Presentation
A young man in his 20s presented to the emergency department with one week of cough and small volume hemoptysis. He has been experiencing several episodes of hemoptysis per day during this time. He says he coughs up about 1/4 cup of blood with each episode. He also adds that for the past 2 weeks he also has noticed worsening nausea, vomiting, headaches, and fatigue. He saw his primary care doctor and he was diagnosed with new hypertension and started on clonidine 0.1 mg three times a day, and provided cough medication. However, his symptoms continued. Given the increasing frequency of the hemoptysis and worsening nausea, he presented to the emergency department.
