Reliability of tuberculin skin test measurement

Article Abstract:

The reader's consistency may be a significant source of error among health care workers who evaluate tuberculin skin tests. Three measurements using two techniques were taken by one of two experienced health care workers on 96 tuberculin skin test reactions. There was a 2.7 millimeter (mm) to 3.7 mm difference in measurements 5% of the time among subsequent measurements done by either the same or alternate observer. These differences are enough to change whether a patient is classified as positive or negative in borderline cases.

The Technologies of Time Measurement: Implications at the Bedside and the Bench

Article Abstract:

The author discusses the introduction of time and its passage into diagnostic and therapeutic medicine, and how that aspect became an important factor in clinical and scientific study. For example, one aspect of this might be variations in body temperature measured over periods of time, and what the particular variances tell the clinician about the physiological condition. He goes on to discuss the case reporting techniques and the method in which information is organized to make it into useful data.

Developments in cervical and ovarian cancer screening: implications for current practice

Article Abstract:

Innovations in medical screening for cervical and ovarian cancer are discussed. As of 2000, there is no cost-effective screening test for ovarian cancer although several tests are under evaluation. The Pap test is the most commonly used test to detect cervical cancer, but it has disadvantages and many women do not have regular Pap tests.
