Abstract: A 62-year-old man presents with a three-day history of progressive dyspnea, nonproductive cough, and low-grade fever. His blood pressure is 100/60 mm Hg, his heart rate 110 beats per minute, his temperature 37.9°C, and his oxygen saturation while breathing room air 86 percent. Chest auscultation reveals rales and rhonchi bilaterally. A chest radiograph shows bilateral pulmonary infiltrates consistent with pulmonary edema and borderline enlargement of the cardiac silhouette. How should this patient be evaluated to establish the cause of the acute pulmonary edema and to determine appropriate therapy?

Abstract: Respiratory syncytial virus (RSV), the most important cause of lower respiratory disease in infants and young children, is rarely considered among the causes for community-acquired lower respiratory infection in adults. All noninstitutionalized adults hospitalized with community-acquired pneumonia in two Ohio counties were evaluated between December 1990 and May 1992. Fifty-three (4.4%) of 1195 adults admitted during the RSV seasons and 4 (1.0%) of 390 in the off-season had serologic evidence of RSV infection, making RSV one of the four most common pathogens identified. RSV-infected patients had clinical features (e.g., wheezing and rhonchi) that distinguished them from all non-RSV-infected patients and other features (e.g., nonelevated white blood cell counts) that distinguished them from those infected with bacterial or atypical agents. However, RSV infection was not diagnosed during hospitalization for any of the 57 RSV-infected patients. RSV should be considered in the differential diagnosis for adults hospitalized between November and April with community-acquired lower respiratory infection.

Abstract: Background A large population in West Bengal, India has been exposed to naturally occurring inorganic arsenic through their drinking water. A cross-sectional survey involving 7683 participants of all ages was conducted in an arsenic-affected region between April 1995 and March 1996. The main focus of the study was skin keratoses and pigmentation alterations, two characteristic signs of ingested inorganic arsenic. Strong exposure-response gradients were found for these skin lesions. The study also collected limited information concerning respiratory system signs and symptoms, which we report here because increasing evidence suggests that arsenic ingestion also causes pulmonary effects. Methods Participants were clinically examined and interviewed, and the arsenic content in their current primary drinking water source was measured. There were few smokers and analyses were confined to non-smokers (N = 6864 participants). Results Among both males and females, the prevalence of cough, shortness of breath, and chest sounds (crepitations and/or rhonchi) in the lungs rose with increasing arsenic concentrations in drinking water. These respiratory effects were most pronounced in individuals with high arsenic water concentrations who also had skin lesions. Prevalence odds ratio (POR) estimates were markedly increased for participants with arsenic-induced skin lesions who also had high levels of arsenic in their current drinking water source (>500 μg/l) compared with individuals who had normal skin and were exposed to low levels of arsenic (,50 μg/l). In participants with skin lesions, the age-adjusted POR estimates for cough were 7.8 for females (95% CI : 3.1‐19.5) and 5.0 for males (95% CI : 2.6‐9.9); for chest sounds POR for females was 9.6 (95% CI : 4.0‐22.9) and for males 6.9 (95% CI : 3.1‐15.0). The POR for shortness of breath in females was 23.2 (95% CI : 5.8‐92.8) and in males 3.7 (95% CI : 1.3‐10.6). Conclusion These results add to evidence that long-term ingestion of inorganic arsenic can cause respiratory effects.

Abstract: To characterize lung sounds objectively, we examined, by means of time-amplitude plots, selected tape recordings of auscultatory phenomena considered by six observers to be typical of those in a standard classification. Normal lung sounds could not consistently be visually distinguished from adventitious sounds at conventional chart recorder speeds of 100 mm per second or less, but the differentiation was easily achieved when the time scale of the plots was raised to 800 mm per second. When discontinuous sounds (rales, crackles or crepitations) were heard clinically, the time-expanded wave forms showed intermittent "discontinuous" deflections usually less than 10 msec in duration. When continuous sounds (rhonchi or wheezes) were heard, the deflections were usually more than 250 msec. Time-expanded wave-form analysis provides reproducible visual displays that allow documentation of the differentiating features of lung sounds and enhances the diagnostic utility of the sounds.

Abstract: Adults presenting to an emergency department with acute respiratory illness were studied prospectively in an effort to identify sensitive clinical criteria for the diagnosis of pneumonia. Of 308 patients studied, 118 (38%) had definite or equivocal infiltrates and were considered to have pneumonia. No single symptom or sign was reliably predictive of pneumonia. Cough was the most common symptom in patients with pneumonia (86%), but was equally common in those with other respiratory illness. Fever was absent in 36 patients with pneumonia (31%). Abnormal findings on lung examination, that is, rales, rhonchi, decreased breath sounds, wheezes, altered fremitus, egophony, and percussion dullness, were each found in fewer than half of the patients with pneumonia. Twenty-six patients (22%) with a completely normal chest examination had pneumonia. Abnormal vital signs (temperature greater than 37.8 degrees C (100 degrees F), pulse greater than 100/min, or respirations greater than 20/min) were 97% sensitive for the detection of pneumonia. These criteria retained their sensitivity when films were subjected to a second, blinded interpretation by a senior radiologist. We conclude that restricting chest roentgenograms to patients with at least one abnormal vital sign will detect almost all radiographically demonstrable pneumonia in adult emergency department patients.
