The polygraph test - a flawed diagnostic method

Article Abstract:

The polygraph test, or 'lie detector' test, may not be a reliable method for evaluating the honesty of an individual's statements. The polygraph test was invented in the early 1900s, and has been used in different types of investigations and for personnel screening. It works on the principle that telling a lie causes a reproducible physiological reaction. Theoretically, telling a lie stimulates the autonomic nervous system causing changes in involuntary processes such as blood pressure, pulse, breathing patterns and perspiration. Proponents of the test believe that polygraph results are as reliable as those of other diagnostic tests such as electrocardiography. Others believe that other factors may affect the validity of polygraph results. Some individuals who undergo testing may experience complex emotions that affect their autonomic nervous system, and change their test results. Others are able to escape detection by tensing their muscles or using certain drugs. Most state and federal courts restrict the use of polygraph test results or do not allow their use.

Battling HIV on many fronts

Article Abstract:

The US needs to develop a coordinated program to deal with HIV infection. While there are many programs and support services for AIDS patients, very little attention is given to people recently infected with HIV. HIV infection should be a reportable disease and the public health response should include contact tracing and partner notification. Patients should have access to effective drugs and physicians with expertise in treating HIV infection. They should also be protected from discrimination. Studies have shown that treatment with combination drug therapy can reduce viral concentrations to undetectable levels.

Private health care in Canada

Article Abstract:

Canada's government-funded universal health care system is characterized by the public provision of core physician and hospital services and the absence of co-payments and other patient charges. Canada is anticipating an infusion of private care for core services and experts believe that an increase in private health care will benefit the public health system.
