Pulmonary radiographs are essential adjuncts to the evaluation and diagnosis of suspected pulmonary disease. In the intensive care unit, radiographs are useful to confirm correct positioning of diagnostic and therapeutic devices. Patterns seen on the radiograph may be within broadly normal limits or may be interpreted as abnormal, especially when placed in the clinical context of a specific patient's problem. The description abnormal can be related to both nonspecific and specific radiographic patterns of disease. Nonspecific radiographic patterns of disease include location of disease, temporal course of disease, pleural abnormalities, hyperinflation, extra-alveolar air, atelectasis, bronchiectasis, and vascular disease. Specific radiographic patterns of disease are discrete anatomic structures seen on a radiograph, for example, cavitary and cystic disease. The interpretation of nonspecific and specific radiographic patterns is useful in diagnosis, selection of treatment, and monitoring of the course of disease and the patient's response to treatment.

Study Objectives: To evaluate the clinical safety, efficacy, and cost of a small indwelling pleural catheter (7F, Turkel Safety Thoracentesis System [Sherwood, Davis, and Geck; St. Louis]) vs repeated needle thoracentesis or closed tube thoracostomy as a means to drain a large-volume pleural effusion., Setting: Inpatients in a tertiary care university teaching hospital in urban Chicago., Design: Prospective, consecutive patient comparative study using historical controls., Patients: Fifty-seven therapeutic aspirations in 23 patients with large pleural effusions as defined by opacification of at least one third of the hemithorax on chest radiography. Patients were excluded if they had a history of thoracic surgery, documented loculations, structural chest abnormalities, severe coagulopathy, or refused to give informed consent., Measurements: Volume of each pleural aspiration, total fluid removed, pleural fluid lactate dehydrogenase, protein, glucose, cytologic analysis, microbiologic stains, and cultures based on clinical indications., Results: We found that initial thoracentesis and repeated pleural drainage using the indwelling catheter system is a safe, efficacious, and cost-effective procedure that may aid the evacuation and management of a large-volume pleural effusion. There were fewer adverse effects and complications such as pneumothorax, splenic laceration, hemopneumothorax, local pain, dry tap, and hematomas, as compared with previous reports. The overall complication rate was 12% (7/57). There were two pneumothoraces detected (3.5%), one of which required closed tube thoracostomy for treatment (1.75%). A further benefit comes in the form of a significant cost savings at our institution ($80 vs $240) when this needle-catheter system is used in place of closed tube thoracostomy in the drainage of a large-volume pleural effusion., Conclusion: An indwelling pleural catheter with the Turkel safety needle-catheter (as described in the study) can be used to successfully drain the pleural space with reduced morbidity and a significant cost saving in comparison to repeated needle thoracenteses or closed tube thoracostomy.

We conducted a worksite cardiovascular disease (CVD) awareness and education program at a large medical center. The program consisted of employee screening for blood pressure and total serum cholesterol level, dissemination of information on risk factors for CVD, counseling on behavior change, and evaluation of the screening event as an educational tool. During this five-day event, 2,284 employees were screened for hypertension and hypercholesterolemia. Consenting employees completed a health risk appraisal survey (n = 2,255) and received counseling on their results and CVD risk factors. Appropriate referrals to health care professionals and educational programs were made according to national guidelines. We developed three-month and six-month follow-up surveys and distributed them to all participating employees. The analysis of these data suggests some positive impact upon behavior change within this employee population. In addition to the two follow-up surveys, we held a second blood pressure and serum cholesterol screening eight months after the initial screening. Comparison of the levels taken from both screenings (n = 234) suggests that worksite screening programs may influence significant serum cholesterol and blood pressure reductions in high-risk employees.
