    Association between level of education and oral health status in 35-, 50-, 65- and 75-year-olds

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 8 2003
    J. Paulander
    Abstract Aim: The aim of the present study was to evaluate the association between educational level and dental disease, treatment needs and oral hygiene habits. Material and methods: Randomized samples of 35-, 50-, 65- and 75-year-olds, classified according to the educational level: [low (LE): elementary school or higher (HE)], were identified. In 1091 subjects, a number of characteristics such as (i) number of teeth, (ii) periodontal attachment levels (PAL), (iii) caries and (iv) occlusal function were recorded. Educational level, oral hygiene and dietary habits were self-reported. Non-parametric variables were analyzed by ,2, Mann,Whitney U,Wilcoxon's rank sum tests, and parametric variables by Student's t -test (level of significance 95%). A two-way anova was performed on decayed, missing and filled surfaces to investigate the interaction between age and educational level. All statistical procedures were performed in the SPSS© statistical package. Results: The number of remaining teeth was similar for LE and HE in the 35-year olds (25.8 versus 26.6), but in the older age groups LE had significantly a larger number of missing teeth. The LE groups (except in 65-year olds) exhibited significantly more PAL loss. LE had significantly fewer healthy gingival units in all but the 75-year age group. In all age groups, LE had fewer intact tooth surfaces and a significantly poorer occlusal function. The frequency of tooth cleaning measures and dietary habits did not differ between LE and HE. Conclusion: Educational level was shown to influence the oral conditions and should be considered in assessing risk, and in planning appropriate preventive measures. Zusammenfassung Ziel: Das Ziel der vorliegenden Studie war die Evaluation der Verbindung zwischen Bildungsniveau und Erkrankungen der Zähne, Behandlungsnotwendigkeit und oralen Hygienegewohnheiten. Material und Methoden: Randomisierte Gruppen von 35-, 50-, 65- und 75-Jährigen, die entsprechend ihres Bildungsniveau: niedriges Niveau (LE): Grundschule oder höheres Niveau (HE) klassifiziert wurden, wurden gebildet. Bei 1091 Personen wurden eine Anzahl von Charakteristika aufgezeichnet: (i) Anzahl der Zähne, (ii) parodontales Stützgewebeniveau (PAL), (iii) Karies, (iv) okklusale Funktion. Bildungsniveau, orale Hygiene und Eßgewohnheiten wurden selbst erfasst. Parameterfreie Variable wurden mit dem Chi-Quadrat test, dem Mann,Whitney U,Wilcoxon Rangsummentest und die parametergebundenen Variablen mit dem Student t -test (Signifikanz-Niveau 95 %) analysiert. Die Zwei-Wege ANOVA wurde auf dem DMF-s durchgeführt, um die Beziehung zwischen Alter und Bildungsniveau zu untersuchen. Alle statistischen Berechnungen wurden mit dem SPSS Statistik Programm vorgenommen. Ergebnisse: Die Anzahl der verbliebenen Zähne war zwischen LE und HE ähnlich bei den 35-Jährigen (25.8 vs. 26.6), aber in den älteren LE-Gruppen waren signifikant höhere Zahlen für fehlende Zähne. Die LE-Gruppen (ohne die 65-Jährigen) zeigten signifikant größeren PAL Verlust. LE hatten signifikant weniger gingivale Gesundheit bei den 75-Jährigen. In allen Altersgruppen hatten die LE weniger intakte Zahnoberflächen und signifikant geringere okklusale Funktion. Die Häufigkeit der Zahnreinigung und die Eßgewohnheiten unterschieden sich zwischen LE und HE nicht. Schlussfolgerung: Das Bildungsniveau hat einen Einfluss auf die oralen Bedingungen und sollte bei der Erfassung des Risikos und bei der Planung geeigneter Präventionsmaßnahmen beachtet werden. Résumé But: Le but de cette étude était d'évaluer l'association entre niveau d'éducation et maladie dentaire, besoins de traitement et habitudes d'hygiène orale. Matériel et méthodes: Des échantillons randomisés de sujets âgés de 35-, 50-, 65- et 75 ans, classés selon leur niveau d'éducation: [Bas (LE): école élémentaire, ou élevé (HE)] furent identifiés. Chez 1091 sujets, on a enregistré les caractéristiques suivantes: (i) nombre de dents, (ii) niveau d'attache parodontal (PAL), (iii) caries et (iv) fonction occlusale. Le niveau d'éducation, l'hygiène orale, et les habitudes alimentaires étaient rapportés par les patients eux-même. Les variables non paramétriques furent analysées par les tests chi carré, Mann,Whitney U,Wilcoxon rank sum, et les variables paramétriques par le test t de Student (niveau de signification 95%). 2-way ANOVA fut réalisé sur le DMFS pour rechercher l'interaction entre l'âge et le niveau d'éducation. Toutes les opérations statistiques furent menées par utilisation de SPSS©. Résultats: le nombre de dents restantesétait semblable pour LE et HE chez les sujets de 35 ans (25.8 vs. 26.6), mais dans les groupes plus âgés, LE présentait un nombre significativement plus important de dents absentes. Le groupe LE (sauf chez les patients de 65 ans) présentait plus de perte de PAL. LE présentait moins d'unités gingivales saines sauf dans le groupe de patients âgés de 75 ans. Dans tous les groupes d'âge, LE avait moins de surfaces dentaires intactes et une fonction occlusale significativement plus faible. La fréquence des mesures de nettoyage dentaire et les habitudes alimentaires n'étaient pas différentes entre les groupes LE et HE. Conclusion: Il est montré que le niveau d'éducation influence les conditions orales et cela doit être pris en considération lors de la mise en évidence du risque et dans la planification de mesures de prévention appropriées.

    Is pleomorphic lobular carcinoma really a distinct clinical entity?

    JOURNAL OF SURGICAL ONCOLOGY, Issue 5 2008
    Claire L. Buchanan MD
    Abstract Background Attempts to define the clinical behavior of pleomorphic lobular carcinoma (PLC) have been limited to small series, and clinical management strategies have yet to be established. We describe our experience with PLC as compared to classic ILC and invasive ductal carcinoma (IDC). Methods From 9/1996 to 5/2003, clinical and histopathologic data for 5,635 patients undergoing primary surgical treatment and sentinel lymph node biopsy for breast cancer were collected. Four hundred eighty one (8.5%) patients were diagnosed with ILC; 3,978 (70.6%) with IDC. Of those with ILC, 356 (74%) patients had material available for pathologic re-review and comprise our study population: 52 were classified as PLC; 298 were classified as classic ILC; and 6 cases were reclassified as IDC. We compared clinical, pathologic, and treatment factors for patients with PLC, ILC, and IDC using the Wilcoxon rank sum and Fisher's exact tests. Results PLC were larger than ILC and IDC (20 vs. 15 vs. 13, P,<,0.001), had more positive nodes (median 1 vs. 0 vs. 0, P,<,0.05) and more frequently required mastectomy (63.5% vs. 38.7% vs. 28.8%, P,<,0.001). In addition, more patients with PLC had developed metastatic disease compared to patients with ILC (11.5% vs. 3.7%, P,<,0.05). Conclusions These findings suggest that PLC is a distinct clinical entity that presents at a more advanced stage and may require more aggressive surgical and adjuvant treatment. J. Surg.

    Prehospital Electrocardiograms (ECGs) Do Not Improve the Process of Emergency Department Care in Hospitals with Higher Usage of ECGs in Non,ST-segment Elevation Myocardial Infarction Patients

    CLINICAL CARDIOLOGY, Issue 12 2009
    Michael T. Cudnik
    Background This article will describe the impact of prehospital electrocardiogram (ECG) use on emergency department (ED) processes of care for non,ST-segment elevation myocardial infarction (NSTEMI) patients and assess the characteristics associated with prehospital ECG use. Methods This is a retrospective, multicenter, observational analysis of NSTEMI patients captured by the National Cardiovascular Data Registry-Acute Coronary Treatment and Intervention Outcomes Network Registry,Get with the Guidelines (NCDR ACTION-GWTG) in 2007. Patient and hospital data were stratified by documentation of a prehospital ECG (pECG). Hospitals were stratified into tertiles of pECG use by higher pECG (>5.6%, n 91), lower pECG (, 5.6%, n = 83), or no pECG (n = 100). Statistical evaluation was done via Wilcoxon rank sum and ,2 tests. Results There were 21 251 patients eligible for analysis. A pECG was documented in 1609 (7.6%) patients. Of 274 hospitals, 100 (36.5%) had no pECGs recorded. Median ED length of stay (LOS) was shorter at no pECG hospitals vs lower pECG hospitals (3.97 h vs 4.12 h, P < 0.05), but not higher pECG hospitals vs no pECG hospitals (3.85 h vs 3.97 h, P = not significant [NS]). A pECG was not associated with an improvement in ED performance metrics (use of aspirin, ,-blocker, any heparin) in the higher pECG hospitals vs no pECG hospitals or the lower pECG hospitals vs no pECG hospitals. Conclusions Use of prehospital ECG in NSTEMI patients is uncommon. In contrast to its impact on reperfusion times in ST-segment elevation myocardial infarction (STEMI) patients, its use does not appear to be associated with an improvement in ED processes of care at the hospital level.

    The effect of home-use fluoride gels on glass,ionomer, compomer and composite resin restorations

    JOURNAL OF ORAL REHABILITATION, Issue 7 2003
    P. Dionysopoulos
    summary The purpose of this study was to investigate the resistance to dissolution by two home-use fluoride gels on the surface integrity of glass,ionomer, resin modified glass,ionomer, compomer and composite resin restorations. Class V cavities prepared in extracted teeth were restored with a glass,ionomer (Fuji II), a resin modified glass,ionomer (Vitremenr), two compomers (Dyract and F-2000) and a composite resin (Z-100). Groups of five specimens of each material were treated for 24 h with one of the following: (i) distilled water, (ii) neutral fluoride gel and (iii) acidulated phosphate fluoride (APF) gel. Surface degradation of the restorations was studied using standard electron microscopy (SEM), rated according to specific criteria and statistically analysed by the Wilcoxon test (rank sums). Acidulated phosphate fluoride was found to have a significant effect on all examined materials, while minimal effects resulted from the neutral fluoride gel compared with the control group.
