Studies have reported an increased risk for asthma following lower respiratory tract infections, but few studies have specifically assessed this risk in children diagnosed with pneumonia in infancy. Furthermore, it is not fully understood whether this association is indicative of a causal relationship or if certain children have a predisposition for both diseases. ⋯ Children diagnosed with pneumonia in infancy have a highly increased risk for prevalent asthma at 4 years, which might have implications for future asthma preventive measures and needs to be considered when assessing the morbidity that can be attributed to pneumonia.

Practice Guideline
Executive Summary Diagnosis and Evaluation of Hypersensitivity Pneumonitis: CHEST Guideline and Expert Panel Report.
The purpose of this summary is to provide a synopsis of evidence-based and consensus-derived guidance for clinicians to improve individual diagnostic decision-making for hypersensitivity pneumonitis (HP) and decrease diagnostic practice variability. ⋯ Diagnosis of HP should employ a patient-centered approach and include a multidisciplinary assessment that incorporates the environmental and occupational exposure history and CT pattern to establish diagnostic confidence prior to considering BAL and/or lung biopsy. Additional research is needed on the performance characteristics and generalizability of exposure assessment tools and traditional and new diagnostic tests in modifying clinical decision-making for HP, particularly among those with a provisional diagnosis.

Sweet's Syndrome (SS), also known as acute febrile neutrophilic dermatosis, is one of several cutaneous inflammatory disorders classified as neutrophilic dermatoses. Respiratory complications are described in <50 cases in the literature,1 without prior report of lung transplantation (LT). This article explains the clinical course of the first patient to receive LT for pulmonary SS and presents evidence suggesting recurrence of the primary lung disease in the allograft.

A 58-year-old man presented to the ED with a 1-week history of progressive weight loss, generalized weakness, unsteadiness, and dizziness. In hospital, he experienced a witnessed episode of loss of consciousness with no observable respirations that lasted for 15 minutes. His arterial blood gas demonstrated hypercapnic respiratory failure, and he required mask ventilation and vasoactive medications. ⋯ The patient's medical history was pertinent for a diagnosis of prostatic carcinoma 3 years previously that was found to be castrate resistant. He had metastases to his hip, ribs, and thoracic spine. Previous treatments had included bicalutamide, docetaxel, and abiraterone; he was receiving leuprolide therapy on presentation.

Case Reports
A 60-Year-Old Man With Dyspnea, Proximal Muscle Weakness, and Pulmonary Arterial Hypertension.
A 60-year-old man with no significant medical history presented to the pulmonology clinic with 2 years of progressive weakness and shortness of breath. Showering and other activities of daily living caused him significant fatigue and dyspnea. He had a 20-pack-year smoking history, but no significant history of alcohol or illicit drug use. ⋯ Physical examination showed mild inspiratory crackles in the lung bases, loud splitting of the second pulmonic valve (P2) with a right parasternal heave, and 2+ pitting edema in the lower extremities. There was muscle weakness, pain, and wasting of the proximal upper and lower extremities, particularly in his legs. He denied any joint pain, and there was no evidence of rash or dysphagia.
