Influence of pain and urinary symptoms on quality of life in young men with chronic prostatitis-like symptoms

BACKGROUND: Our aims in the present study were to estimate the influences of pain and urinary symptoms on quality of life, and to determine which of these two variables has the most predictive power with respect to quality of life in young men with chronic prostatitis-like symptoms. METHODS: Chronic prostatitis-like symptoms were measured by the National Institutes of Health-Chronic Prostatitis Symptom Index. Of the 28,841 men aged 20 years who lived in the study community, 18,495 men (a response rate 64.1%) agreed to participate in the study. A total of 1057 men who complained of symptoms indicative of chronic prostatitis were included in the study. The influences of pain and urinary symptoms on quality of life were determined using logistic regression analysis. The receiver operating characteristic (ROC) curve was used to estimate the predictive ability of each of these variables with respect to quality of life. RESULTS: Results from multivariate analysis showed that both pain and urinary symptoms were associated with an increased likelihood of impaired quality of life, although pain contributed more to a reduced quality of life than urinary symptoms. Relative to men who experienced mild pain, men who experienced moderate pain had a 3.9-fold risk of poor quality of life (odds ratio [OR], 3.87; 95% confidence interval [CI], 2.86-5.23; P < 0.001) and those who experienced severe pain had a 15.7-fold risk of reduced quality of life (OR, 15.68; 95% CI, 6.59-37.35; P < 0.001). Moderate urinary symptoms were associated with a 1.4-fold risk of bother (OR, 1.41; 95% CI, 1.01-1.99; P < 0.001) and severe urinary symptoms were associated with 2.4-fold risk (OR, 2.39; 95% CI, 1.37-4.12; P < 0.001), relative to mild urinary symptoms. Comparison of the effects of pain and urinary symptoms showed that pain severity had the most predictive power for bother, quality of life, and quality-of-life impact. The areas under the ROC curves for bother, quality of life, and quality-of-life impact were 71.3%, 69.3% and 72.5%, respectively. CONCLUSION: Urinary symptoms and pain might be associated with an increased likelihood of impaired quality of life in young men with chronic prostatitis-like symptoms. In addition, our findings suggest that pain severity is the most influential variable for determining quality of life in this population.     

Appropriateness of digoxin use in medical outpatients

PURPOSE: Digoxin is the third most commonly prescribed drug, yet limited information exists about its use in outpatients. Therefore, 242 medical outpatients receiving digoxin at our hospital were studied to evaluate the appropriateness of its use, defined by: (1) current or past supraventricular arrhythmias and/or (2) left ventricular systolic dysfunction (ejection fraction less than 45 percent). PATIENTS AND METHODS: Charts of 242 patients receiving digoxin were obtained. The patients were divided into groups based upon their physician's stated indication for digoxin therapy. Patients with only a clinical diagnosis of congestive heart failure (CHF) underwent echocardiography or radionuclide angiography to quantify left ventricular systolic function. Those with documented supraventricular arrhythmias and/or those with confirmed left ventricular systolic dysfunction were classified as appropriate candidates for digoxin. RESULTS: Ninety-five percent of patients received digoxin for appropriate indications; 75 percent had confirmed supraventricular arrhythmias (27 percent also had CHF) and 20 percent with normal sinus rhythm had documented systolic dysfunction. However, physicians had difficulty in the clinical assessment of left ventricular function; 18 percent of patients with sinus rhythm and CHF by the Framingham scoring system and 20 percent of those with supraventricular arrhythmias and CHF had preserved systolic function. An S3 was present in 15 percent of patients with preserved ejection fraction and CHF and in 69 percent with low ejection fraction; hypertension was significantly more common in the former group. Noninvasive assessment of systolic function was obtained in 97 percent of patients independent of this study, yet some patients without supraventricular arrhythmias and with documented preservation of systolic function continued to receive the drug. CONCLUSION: Noninvasive assessment of left ventricular function, which appears to have become routine, is of value in the appropriate utilization of digoxin, since clinicians' assessment of left ventricular function may be inaccurate. Physicians also do not always discontinue digoxin therapy when indicated.
