Chronic rhinosinusitis: phenotypes and endotypes.

PURPOSE OF REVIEW: Chronic rhinosinusitis (CRS) is a broad classification of airway inflammation that affects a significant portion of the population. The current model of delineating patients suffering from CRS is dated and is no longer as simple as the presence of polyps or no polyps. Continued advances in the endotype descriptions of CRS have allowed for new phenotypic descriptions that aid in driving management and research efforts. RECENT FINDINGS: Geographic differences exist between patient presentations, which require a molecular evaluation of the driving forces. Increased understanding of these differences allows for patient-specific treatment decisions. SUMMARY: New descriptions of CRS phenotypes allow for more targeted therapy for patients, particularly to those with difficult to control disease. The previously broad classification of CRS with or without nasal polyps is no longer sufficient at driving these treatment decisions.

Flat sticker as a mobile airway foreign body: A case report and review of the literature.

Diagnosis of an airway foreign body in the setting of an unwitnessed aspiration event remains a challenge for physicians in the emergency setting. We describe a case of a 2-year-old male who presented to the emergency department with atypical symptoms resulting from ingestion and aspiration of a large, flat sticker. The airway foreign body remained in place for over 24 hours despite obtaining appropriate airway imaging, and the object was later removed without complication via rigid bronchoscopy in the operating room. Further review of this case and the current literature highlighted multiple lessons. Initial evaluations should combine a rigorous history and physical with strict guidelines on usage of multiple imaging modalities (eg, plain radiographs and CT). Imaging should be obtained with the patient devoid of all obstructive materials in multiple positions (eg, upright, supine, lateral) in order to maximize the physician's ability to positively diagnose airway foreign bodies prior to definitive treatment with rigid bronchoscopy.

Association of Urine Albumin Excretion With Incident Heart Failure Hospitalization in Community-Dwelling Adults.

OBJECTIVES: This study examined the association between urinary albumin excretion and incident heart failure (HF) hospitalization. BACKGROUND: Excess urinary albumin excretion is more strongly associated with incident stroke and coronary heart disease risk in black than in white individuals. Whether similar associations extend to HF is unclear. METHODS: This study examined the associations between the urinary albumin-to-creatinine ratio (ACR) and incident hospitalization for HF overall in 24,433 REGARDS (Reasons for Geographic and Racial Differences in Stroke) study participants free of suspected HF at baseline; findings were stratified by race and HF subtype (preserved vs. reduced ejection fraction). Models were adjusted for sociodemographic, clinical, and laboratory variables including estimated glomerular filtration rate, and multiple imputation was used to account for missing covariate data. RESULTS: After a median follow-up of 9.2 years, 881 incident HF events (332 preserved ejection fraction, 447 reduced ejection fraction, 102 unspecified) were observed. Compared to the lowest ACR category (<10 mg/g), the risk of incident HF increased with increasing ACR categories (10 to 29 mg/g hazard ratio [HR]: 1.49; 95% confidence interval [CI]: 1.26 to 1.78; 30 to 300 mg/g HR: 2.32; 95% CI: 1.93 to 2.78; >300 mg/g HR: 4.42; 95% CI: 3.36 to 5.83) in the fully adjusted model. Results did not differ by race. The magnitude of the association between ACR and HF with preserved ejection fraction was greater than with HF with reduced ejection fraction (HR comparing highest vs. lowest ACR category: 6.20; 95% CI: 4.15 to 9.26 vs. HR: 4.37; 95% CI: 3.00 to 6.25, respectively; p = 0.05). CONCLUSIONS: Higher ACR was associated with greater risk of incident HF hospitalization in community-dwelling black and white adults.
