The latest Centers for Disease Control and Prevention (CDC) guidelines recommend routine HIV screening for a large segment of the population, given that the individual understands that an HIV test will be performed unless he or she declines testing (opt-out testing). The CDC recommendation calls for the elimination of formalized requirements for written consent and pretest counseling to encourage more Americans to voluntarily accept testing. Knowledge of HIV infection can increase early access to care and treatment and reduce further transmission. A rapid non-invasive test for HIV infection (OraQuick Advance) from oral fluid has recently become available. It offers two distinct advantages: 1) results are available within twenty minutes, thereby eliminating a long waiting period; and 2) it has high sensitivity and specificity comparable to blood testing. A preliminary positive test result must be confirmed with a Western Blot by an outside laboratory or physician. Important ethical and legal issues must be resolved before the successful implementation of HIV testing in the dental setting. An educational emphasis on broader coverage of HIV testing is also needed within the dental school curriculum. The integration of HIV testing into dental practice is discussed as well. A policy of screening patients in dental offices will contribute to a major advance in public health

Physicians treating newly incapacitated patients often must help navigate surrogate decision-makers through a difficult course of treatment decisions, while safeguarding the patient's autonomy. We offer guidance for intensive care physicians who must frequently address the difficult questions concerning disclosure of confidential information to surrogates. Three clinical vignettes will highlight the ethical challenges to physician disclosure of a critically ill patient's HIV status. Two key distinctions are offered that influence the propriety of disclosure: first, whether HIV infection represents a 'primary cause' for the patient's critical illness; and second, whether the surrogate may be harmed by failure to disclose HIV status. This balanced consideration of the direct duties of physicians to patients, and their indirect duties to surrogates and third-party contacts, may be used as a framework for considering other ethical obligations in the intensive care unit. We also provide a tabulation of individual US state laws relevant to disclosure of HIV status

BACKGROUND: The American Diabetes Association has established recommendations for the testing of undiagnosed people. Once diagnosed, those with diabetes must strive to maintain a level of glucose control that results in a metabolism that approaches that of people without diabetes. The dentist also can provide risk-reduction strategies for people prone to develop diabetes, and refer patients with signs and symptoms suggestive of diabetes to physicians. METHODS: The authors describe criteria for establishing a diagnosis of diabetes and for identifying people at high risk of developing the disease. A combination of approaches in the medical management of type 1 and type 2 diabetes mellitus is presented, along with target outcomes. RESULTS: Patients with diabetes maintain a glycosylated hemoglobin value of no higher than 7 percent. New therapeutic research includes early clinical trials of islet cell transplantation and therapeutic cloning from human stem cells, which may provide an alternate source of insulin-producing islet cells and, thus, may offer a potential cure for diabetes. CONCLUSIONS: Rigorous metabolic control of diabetes can be achieved through a combination of therapeutic modalities and the establishment and maintenance of target outcomes. The dentist can implement preventive strategies and refer patients with signs and symptoms suggestive of diabetes to physicians. CLINICAL IMPLICATIONS: The dentist and physician must work together as a team to achieve rigorous metabolic control of diabetes in their patients
