Fever of unknown origin (FUO) has been defined as a fever of ≥101°F that persists for 3 weeks or more. It is not readily diagnosed after 1 week of intensive in-hospital testing or after intensive outpatient or inpatient testing. Fevers of unknown origin may be caused by infectious diseases, malignancies, collagen vascular diseases, or a variety of miscellaneous disorders. The relative distribution of causes of FUOs is partly age-related. In the elderly, the preponderance of FUOs is attributable to neoplastic and infectious etiologies, whereas in children, collagen vascular diseases, neoplasms, and viral infectious disease predominate. The diagnostic approach to FUOs depends on a careful analysis of the history, physical findings, and laboratory tests. Most patients with FUOs exhibit localizing findings that should direct the diagnostic workup and limit diagnostic possibilities. The most perplexing causes of FUOs involve those without specific diagnostic tests, e.g., juvenile rheumatoid arthritis (JRA) or adult Still's disease. In a young adult with FUO, if all of the cardinal symptoms are present, JRA may present either a straightforward or an elusive diagnosis, if key findings are absent or if the diagnosis goes unsuspected. ⋯ Diagnostic fever curves are most helpful in cases where the diagnosis is most elusive, as was the case here. Relatively few disorders are associated with a double quotidian fever, ie, visceral leishmaniasis, mixed malarial infections, right-sided gonococcal acute bacterial endocarditis, and JRA. Because the patient received antipyretics during the first week of admission, fever was not present. After infectious disease consultation during week 2 of hospitalization, antipyretics were discontinued, and a double quotidian fever was present, which provided the key diagnostic clue in this case.

Randomized Controlled Trial Multicenter Study Comparative Study
The role of the endotracheal tube cuff in microaspiration.
The cuff of the endotracheal tube (ETT) is designed to provide a seal within the airway, allowing airflow through the ETT but preventing passage of air or fluids around the ETT. Deliberate or inadvertent movement of the ETT may affect cuff pressure or shift folds in the cuff, mobilizing pooled secretions. ⋯ These complications are costly in terms of morbidity and mortality, as well as hospital expense. We will discuss the role of the ETT cuff in microaspiration and identify potential directions for future research to improve outcomes in mechanically ventilated patients.

After hospitalization for a cardiac event, older adults are frequently discharged to a skilled nursing facility (SNF) for postacute care. The American Association of Cardiopulmonary Rehabilitation recommends that cardiac care be integrated into procedures at SNFs. ⋯ The integration of cardiac care into SNFs is important to ensure the safety of therapy and improve the transition of patients from SNFs to outpatient cardiac rehabilitation programs.

Randomized Controlled Trial Comparative Study
Inexperienced nurses and doctors are equally efficient in managing the airway in a manikin model.
The aim of the present study was to investigate whether minimally trained medical and nursing school graduates would be equally efficient in placing a laryngeal mask airway (LMA) and in intubating the trachea with the Macintosh blade or a videolaryngoscope in a manikin model. Airway management is an essential skill for both physicians and nurses who may be confronted with a critically ill patient, because in the emergency department the airway is not exclusively managed by medical personnel. Several studies have shown that other healthcare professionals are not any less efficient in securing the airway. ⋯ Nurses are as efficient as physicians in managing the airway safely and adequately with the 3 different techniques in manikins.

Lipoid pneumonia (LP) is a rare type of pneumonia that is radiologically characterized by lung infiltrates, although imaging alone may not be diagnostic. We describe an unusual 61-year-old patient with idiopathic LP presenting as a solitary pulmonary nodule mimicking lung cancer because of its rapid growth. After treatment with oral prednisone, a control chest radiogram indicated complete normalization of the radiologic features. This case shows that LP should be considered in the diagnostic assessment of any undefined pulmonary mass, after malignancy has been pathologically excluded.
