Effective immunity to dental caries: passive transfer to rats to antibodies to Streptococcus mutans elicits protection

Rat dams, given intravenous injections of heat-killed Streptococcus mutans 6715, mutant C211 demonstrated significant agglutinin activity to the homologous S. mutans in colostrum, milk, and serum. This antibody activity was associated with the immunoglobulin G (IgG) class. High titers of anti-S. mutans antibody associated with the IgG class were also exhibited in the sera and saliva of the offspring that suckled these dams. After challenge with the homologous, live S. mutans, these offspring developed significantly fewer caries on all molar surfaces than did nonimmunized infected controls. A secretory immune response (manifested by the presence of specific IgA antibody to S. mutans in colostrum and milk) was elicited (i) in rat dams locally injected, in the region of the mammary gland, with heat-killed S. mutans antigen, and (ii) in other rat dams that were provided formalin-killed S. mutans in their drinking water. Offspring suckling these dams were challenged with virulent S. mutans before weaning and developed significantly fewer caries than did their infected controls. These findings clearly suggest that passively derived IgG or IgA antibodies to S. mutans are protective against dental caries.     

Counseling patients to quit smoking. What to say, when to say it, and how to use your time to advantage

Helping patients stop smoking is one of the most important--and frustrating--services primary care physicians can provide. Many physicians are reluctant to spend time talking about tobacco use with patients who show little or no interest in changing their habits. Fortunately, specific technique have been identified that can make the task easier. This article from the distinguished Nicotine Dependence Center of the Mayo Clinic looks at the "best practices" for dealing with nicotine dependence.     

Glutamic acid decarboxylase--gene to antigen to disease

Glutamic acid decarboxylase (GAD) enzymes catalyse the formation of gamma-aminobuturic acid (GABA), which is a major transmitter in the central nervous system but also exerts functions in peripheral organs. Recent-molecular analyses have revealed surprising new roles for the GAD isoforms in human diseases of autoimmune character including neurological disorders and insulin-dependent diabetes. In the 1995 Frontiers in Medicine Symposium, the co-authors of this review discussed the genetics, cell biology, molecular immunology and the role of GAD as autoantigens in human autoimmunity. Studies on disease diagnosis, prediction, and prognosis have revealed unique patterns of reactivities in both cellular and humoral immune responses. Further work will be needed to establish whether the GAD molecules can be used to treat autoimmune diseases.     

Reply to Hyman and to Levy.

Replies to the objections of A. Hyman (1981) and S. M. Levy (1981) concerning the author's (see record 1980-10503-001) rejection of psychotherapy as the treatment of choice in health-habit modification (HHM). The case is restated for a shift away from an emphasis on intrapsychic variables in HHM. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Multimedia to teach urology to medical students

OBJECTIVES: To test the hypothesis that an interactive multimedia-based computer application may be used to teach urology to undergraduate medical students. METHODS: Third-year medical students rotating on their urology clerkship were studied. Student knowledge was measured with a multiple choice test administered in a pretest-post-test experimental design. The educational intervention was a multimedia-based application that presented a clinical module on hematuria, using natural language-like entries. Student attitudes toward the multimedia application were assessed by a survey. RESULTS: Twenty-three consecutive third-year medical students participated. Mean pretest and post-test scores +/- standard deviation were 35%+/-11% versus 74%+/-17%, respectively, P<0.0001. Student questionnaire responses indicated highly positive opinions that the multimedia-based module was easy to use, was fun, provided natural patient responses, had clear exercises, provided immediate feedback, was educational, and had a nonthreatening format, and that the multiple choice questions were clear and fair. CONCLUSIONS: Multimedia-based education may be used to teach urology to undergraduate medical students.
