Oral healthcare of the patient receiving chemotherapy and/or marrow transplantSolomon, Charlene S. January 1996 (has links)
Magister Scientiae Dentium - MSc(Dent) / Between September 1992 and August 1995, all patients with haematological malignancies who
were treated as in-patients in the Haematology Unit at Groote Schuur Hospital received a twice
weekly, oral and perioral examination. Sixty patients were monitored while following the
traditional hospital oral care protocol (chlorhexidine, hydrogen peroxide, sodium bicarbonate,
thymol glycol, benzocaine mouthrinse and nystatin). The mouth care protocol was then changed
(protocol A = chlorhexidine, benzocaine lozenges, amphotericin B lozenges) and patients
monitored until the sample size matched that of the hospital mouth care regimen (n = 60). A
further 60 patients were then monitored using a third protocol (protocol B = benzydamine
hydrochloride, chlorhexidine, benzocaine lozenges, amphotericin B lozenges). A statistically
significant reduction in oral complications was found upon introduction and maintenance of
protocols A and B. The findings of this study suggest that improved oral care and a structured
oral care routine reduces the number of oral complications associated with chemo- and
radiotherapy. / Medical Research council

Periodontal Inflamed Surface Area (PISA)— Psychometric Evaluation and Biological Correlates of a Promising Index for Measuring Periodontal InflammationAlnasser, Lubna January 2022 (has links)
Periodontal inflammation is a hallmark of periodontitis and a primary driver of progressive periodontal tissue destruction. In addition, inflammation is hypothesized as a critical mechanistic intermediate linking periodontal disease to systemic inflammation and extra-oral disease outcomes. However, most of the commonly used measures of periodontitis, for research and/or surveillance purposes, focus on quantifying the periodontal tissue loss (i.e., gingival recession (GR) and clinical attachment loss (CAL)). There are few indices that focus on quantifying periodontal inflammation in the periodontal literature, and there are inherent limitations in the way they are calculated.
The Periodontal Inflamed Surface Area (PISA) is a composite measure that incorporates bleeding on probing (BOP) and other measures of periodontal disease to quantify the amount of periodontal inflamed surfaces. This dissertation examined PISA as a useful measure that attempted to quantify periodontal inflammation, and it is divided into three parts. The first paper is a scoping review focused on reviewing the relevant literature around PISA since its introduction to the literature in 2008. The second paper is an empirical paper that examined the psychometric properties of PISA compared to other measures of periodontitis.
The third paper is another empirical study that explored how PISA correlated with some biological features of periodontitis, including the subgingival microbial profile, systemic immune response, and selected dysbiosis indices. The empirical papers utilized data from two population-based cohorts: the Oral Infections, Glucose Intolerance, and Insulin Resistance Study (ORIGINS) and the Washington Heights Inwood Community Aging Project's Ancillary Study of Oral Health (WHICAP-OH). The review found that PISA was primarily utilized in studies that looked at oral-systemic health connections, with results that mostly confirmed the associations between periodontal disease and systemic health. However, most evidence suffered from methodological concerns that could limit the validity and generalizability of results. The psychometrics analyses showed that PISA had good sensitivity, specificity, and accuracy in identifying patients with periodontitis.
The latent factor analyses suggested a multi-level three-factor model showing PISA to cluster with bleeding on probing in the same factor that indicates an inflammation component of the unobserved periodontal disease status. The third paper showed that PISA was significantly associated with alpha diversity indices (Shannon's, Simpson's, and Faith's phylogenetic diversity) and two of the dysbiosis indices in both cohorts. The strength of associations and amount of variance explained in some of the biological features were higher for PISA than other measures of periodontitis. The evidence from this dissertation suggests that PISA is a valuable index that describes periodontal inflammation and has good psychometric properties. Future research can explore the replication of our methods in other cohorts to expand the validity and utility of PISA in periodontal literature.

recognition and Incision of Oxidative Intrastrand Cross-Link Lesions by UvrABC NucleaseMattar, Costy, Keith, Rob L., Byrd, Ryland P., Roy, Thomas M. 01 August 2006 (has links)
Septic pulmonary embolization (SPE) is a rare but serious disorder. It is a well-recognized potential problem in the settings of tricuspid valve endocarditis, septic thrombophlebitis, infected central venous catheters, and postanginal septicemia. Less well documented is the occurrence of SPE in patients with periodontal disease without suppurative thrombophlebitis of the great vessels of the neck. We report a patient with SPE in whom periodontal disease was the only identifiable nidus of infection and review the literature regarding the four other patients reported to have suffered this complication.

ANTIBIOTIC RESISTANCE OF PERIODONTAL PREVOTELLA INTERMEDIA/NIGRESCENS IN 2011 AND 2021Chrobocinski , Kaitlin A January 2022 (has links)
Prevotella intermedia/nigrescens group bacteria are Gram-negative, non-motile, anaerobic rods abundant in the subgingival microbiome of human periodontitis patients, and relatively sparse in persons with periodontal health. P. intermedia/nigrescens may be inadequately suppressed in periodontal pockets with conventional mechanical-surgical forms of periodontal therapy. Therefore, short-term systemic antibiotic therapy is often recommended in the treatment of recalcitrant (refractory) severe periodontitis patients where high numbers of P. intermedia/nigrescens persist in the subgingival microbiota. Limited available data suggests that the antibiotic sensitivity profile of periodontal P. intermedia/nigrescens has changed over time among severe periodontitis patients in the United States, with increasing levels of antibiotic resistance reported. These findings have potentially important clinical implications for dental professionals and their severe periodontitis patients which need further confirmation and clarification. To further expand knowledge on this clinically relevant issue, the purpose of the present study was to determine and compare over a 10-year period (2011 versus 2021) the prevalence of in vitro resistance of periodontal P. intermedia/nigrescens to the antibiotics amoxicillin, metronidazole, clindamycin, and doxycycline. / Oral Biology
