This study compared the intra- and inter-examiner reliability of the Florida Probe, Florida Disk Probe, and conventional periodontal probe. Using these instruments, each of three examiners made repeated measurements of probing depth (using the Florida Probe and conventional probe), relative attachment level (using the Florida Disk Probe), and clinical(More)
This study compared the intra- and inter-examiner measurement error of the Florida Probe, Florida Disk Probe, and conventional periodontal probe in persons having moderate to severe periodontitis. Single pass measurements using the conventional probe were compared to both single and double pass (corrected) measurements using the Florida Probe and Florida(More)
CONTEXT Hypertrophic cardiomyopathy (HCM) has been regarded as a disease that causes substantial disability, with annual mortality rates of up to 6%, based largely on reports from tertiary referral centers. OBJECTIVE To assess the clinical course of HCM in a patient cohort more closely resembling the true disease state. DESIGN Retrospective cohort(More)
BACKGROUND Active compression-decompression (ACD) CPR combined with an inspiratory impedance threshold device (ITD) improves vital organ blood flow during cardiac arrest. This study compared survival rates with ACD+ITD CPR versus standard manual CPR (S-CPR). METHODS AND RESULTS A prospective, controlled trial was performed in Mainz, Germany, in which a(More)
OBJECTIVES Reliable prevalence data would be useful in assessing the impact of sudden cardiac death in young competitive athletes on the community and designing effective preparticipation screening strategies. BACKGROUND The frequency with which these catastrophes occur is largely unknown. METHODS We utilized a circumstance unique to Minnesota in which(More)
BACKGROUND, AIMS The primary purpose of this study was to determine the association of salivary and gingival crevicular fluid (GCF) cotinine levels with periodontal disease status in smokers and non-smokers. METHODS 147 male smokers and 30 male non-smokers were included in the current longitudinal study. The 177 individuals were part of a group of 200(More)
This investigation was designed to compare the predominant plaque micro-organisms from a Chinese group of patients exhibiting periodontitis with an age-, sex- and periodontal disease-matched Caucasian group of patients. In addition to race, the 2 population groups differed with respect to diet and oral hygiene habits, or effectiveness at removing plaque.(More)
Some bacterial antigens such as S. aureus enterotoxins can selectively stimulate T cells that express specific V beta genes of the T cell antigen receptor (TCR). The purpose of this study was to investigate whether or not periodontal bacteria could similarly alter the expression of V beta families within the TCR complex. Peripheral blood mononuclear cells(More)
We analyzed pre- and postoperative data from 36 consecutive patients, who developed acute renal failure requiring hemodialysis after open heart surgery, to determine which factors predicted survival. Seventeen patients (47%) survived. Age, sex, preoperative renal dysfunction, severity of underlying heart disease, perioperative myocardial infarction,(More)
Gingivitis and periodontitis are among the most common diseases known to man. Although bacterial plaque is generally accepted as the primary etiologic agent, little information is available concerning the influence that host genetic factors have on these diseases. The purpose of the present study was to examine the relative contribution of environmental and(More)
