A 24-year-old woman, a baby-sitter with no known comorbidities, presented to the outpatient department with complaints of modified Medical Research Council grade IV breathlessness for 3 months, chest pain, and dry cough for 2 weeks. There was no known disease history, including respiratory, flu-like illness, or connective tissue disorder. ⋯ A review of systems was negative for fever, arthralgia, myalgia, Raynaud phenomenon, skin thickening, rash, or leg swelling. The patient had no family history suggestive of a genetic syndrome.

Malignant pleural effusions (MPEs) often cause symptoms, and guidelines recommend early definitive intervention. However, observational data suggest that systemic anticancer treatment (SACT) may control MPE caused by certain pharmacologically sensitive tumors. ⋯ In this observational study, SACT was not associated independently on MPE resolution in pharmacologically sensitive tumors. Randomized trials are required, but with current data, patients with symptomatic MPE should receive early definitive pleural intervention regardless of underlying tumor or intended treatment.

Paracoccidioidomycosis (PCM), or blastomycosis in South America, is a systemic granulomatous mycosis related to activities associated with soil management, especially agriculture. PCM restricted to tracheobronchial tree region has not yet been reported.

An 8-month-old previously healthy, full-term girl presented with altered mental status after falling approximately 3 feet from a bed, landing on her head. In the ED, she had a CT scan of her head (Fig 1) and was intubated for airway protection. While in the PICU, initial chest radiography showed bilateral infiltrates that were consistent with ARDS, which subsequently resolved. ⋯ Lumbar puncture results were obtained, which were unremarkable. Extubation was attempted again on hospital days 15 and 22 with subsequent hypercapnia that required reintubation. She was able to gradually lengthen her CPAP trials but continued to have periods of hypercapnia and bradypnea.

Pseudomonas aeruginosa (PA) is a common cause of respiratory infection and morbidity. Pseudomonas elastase is an important virulence factor regulated by the lasR gene. Whether PA elastase activity is associated with worse clinical outcomes in ICU patients is unknown. ⋯ Elastase activity is associated with 30-day ICU mortality. A high elastase producing clinical isolate confers increased lung tissue inflammation compared with a low elastase producer in vivo.
