Case Reports
A 24-Year-Old Man With Hemoptysis Found to Have a Chest Mass and Contralateral Axillary Lymphadenopathy.
A 24-year-old man, never smoker, with no medical or surgical history, not currently on medications, presented to the ED with a second episode of gross hemoptysis, 4 months after an initial episode that had not previously been evaluated. He described the current episode of hemoptysis as "enough to fill the sink"; however, he did not further quantify. He has no history of recurrent epistaxis, hematemesis, or other evidence of clotting disorder. ⋯ He had no lower extremity pain or swelling. He routinely exercises and generally lives a healthy lifestyle. He is a health care worker who has not routinely worked with patients infected with SARS-CoV-2, although he received his second (of two) COVID-19 vaccines 4 days before presentation.

Posttraumatic stress disorder (PTSD) has been linked to respiratory symptoms and functional limitations, but the mechanisms leading to this association are poorly defined. ⋯ A diagnosis of PTSD was associated with a reduced anaerobic threshold, oxygen pulse, and peak oxygen uptake. This objective reduction in cardiopulmonary work is independent of baseline lung function, was not associated with abnormalities in gas exchange or respiratory reserve, and may be related to deconditioning.

A 60-year-old man with a history of COPD, uncontrolled diabetes (hemoglobin A1c, 10.6%), obesity (BMI, 33.4), and a family history of Ehlers-Danlos syndrome came to the ED with several hours of acute-onset severe left mid-axillary pleuritic chest pain without alleviating factors. The pain had no specific triggers, including activities or heavy meals. It was associated with nausea, chills, and diaphoresis; also, it was preceded by a few weeks of subacute flulike symptoms for which he did not seek medical attention. He denied previous similar symptoms, recent trauma, or surgeries.

A 49-year-old woman presented to the ED with sudden onset abdominal pain, nausea, and vomiting. Her medical history included an uncomplicated gastric lap band surgery 9 years ago and subsequent removal of lap band after 6 years. ⋯ The patient denied smoking and heavy alcohol consumption. She was currently employed as a scrub technician in a local surgical center.

Hypersensitivity pneumonitis (HP) is an inflammatory and/or fibrotic disease affecting the lung parenchyma and small airways. It typically results from an immune-mediated reaction provoked by an overt or occult inhaled antigen in susceptible individuals. ⋯ Given the high prevalence of foam in pillows and mattresses, mold in foam in bedding may explain many HP cases with a previously unrecognized cause. Early identification and avoidance of foam in bedding may prevent HP progression to end-stage pulmonary fibrosis and death.
