The Efficacy of Powered Oscillating Heads vs. Powered Sonic Action Heads Toothbrushes to Maintain Periodontal and Peri-Implant Health: A Narrative Re…
2021
Objectives: To compare the efficacy of rotating-oscillating heads (ORHs) VS sonic action heads (SAHs) powered toothbrushes on plaque accumulation and gingival inflammation. Methods: An electronic (MEDLINE, Embase, Inspec, PQ SciTech and BIOSIS) and a complementary manual search were made to detect eligible studies. RCTs meeting the following criteria were included: final timepoint longer than 15 days; year of publication after 2000; patients without orthodontic appliances or severe systemic/psychiatric diseases. Studies comparing two or more different types of sonic/roto-oscillating toothbrushes were excluded. Selection of articles, extraction of data, and assessment of quality were made in…
Dentifrices : an update
2010
Objectives; The objective of this paper was to review the published evidence concerning the efficacy and potential for adverse reactions of modern dentifrices toothpastes. Data sources; Publications cited on MEDLINE since 1990. Some further pre-1990 publications are also referenced. Data selection; Studies concerning the efficacy of dentifrices and their components and any related putative adverse incidents. Data extraction; Papers were scrutinised for scientific and trial data. Data synthesis; Data concerning the efficacy of dentifrice components were summarised. Conclusions; The efficacy of fluoride salts in dentifrices in reducing dental caries is well established. Toothpastes, containin…
Update on the Management of Pediatric Psoriasis: An Italian Consensus
2022
Introduction Psoriasis affects children with a considerable burden in early life. Treating pediatric psoriasis is challenging also because of the lack of updated specific guidelines. With the recent approval of several biologics for pediatric psoriasis and the ongoing COVID-19 pandemic, the management of young psoriatic patients is facing major changes. A revision of treatment recommendations is therefore needed. Methods In September 2021, a board of six Italian dermatologists convened to update treatment recommendations. The board issued evidence- and consensus-based statements covering relevant areas of pediatric psoriasis, namely: assessment of psoriasis severity, management of children …
Approche géographique des approvissionnements en plaquettes foréstières des chaufferies du secteur collectif/tertiaire : application au Pays Loue-Lis…
2011
In a context of strong increase of fuelwood demand in the collective sector, the supply issue becomes central to all stakeholders, raising many issues relating to land and forestry planning, local development, environment ... Meanwhile, questions emerge: how much energy can be mobilized sustainably? Does the spatial and structural configuration of forests influence the supply process? Do we seek to minimize transport distances? Can we observe spatial competition between the boilers ? To understand the current organization of supplies, we analyzed two sets of data traceability of wood chips. Then, we have developed a model of local supply basins, considering constraints of renewability of th…
Caracterización de la función inmunitaria y plaquetaria en mamíferos marinos y sus alteraciones inducidas por el estrés, patologías o contaminantes m…
2021
El ecosistema marino está siendo sometido de forma incesante a la influencia humana. Los mamíferos marinos, al ser animales longevos que se encuentran en lo alto de la cadena alimentaria son buenos bioindicadores del estado del medio marino. Entre los impactos que más afectan a los mamíferos marinos de vida libre se encuentran la contaminación química, física y acústica, la pesca accidental y el calentamiento global. Diversos estudios han demostrado la presencia de contaminantes en los tejidos de mamíferos marinos varados. Por otro lado, algunos estudios han demostrado la presencia en el agua del mar de xenobióticos que todavía no se han analizado en los tejidos de los mamíferos marinos has…
Evaluación de la eficiencia de la incorporación de pruebas hematológicas al control preoperatorio de pacientes odontoestomatológicos hospitalarios
2015
El manejo del paciente antiagregado en el ámbito odontológico es un tema ampliamente debatido en la literatura actual. Existen diferentes protocolos en los que se diferencian las actuaciones dependiendo del tipo de procedimiento. En los procedimientos simples o menores, parece generalmente establecida la no necesidad de supresión del tratamiento antiagregante oral (AAO). Sin embargo, en los procedimientos mayores, complejos o invasivos existen dudas sobre la decisión a seguir y se presentan varios dilemas como el tiempo de supresión de AAO, los riesgos de supresión o no en relación a la patología que indicó la antiagregación, el manejo de casos de tratamiento antiagregante combinado, o en c…
Optimization of the detection of bacteriophages induced from Listeria sp.
1997
It is necessary to isolate new phages in order to improve the rate of typeability of Listeria monocytogenes strains. We propose a method which increases the detection of induced phages in the presence of inhibitory substances synthesized or liberated by the cells during phage production. Of the 29 phages isolated, 11 (38%) were detected by the spot-on-the-lawn technique and 18 (62%) were revealed by the soft-agar technique. To increase the rate of phage detection, both techniques appear useful. Listeria cultures were subjected to phage typing procedures utilizing these newly isolated phages and the French International set of phages. It appears that the newly isolated phages are good tools …
Purified Membrane-Containing Procapsids of Bacteriophage PRD1 Package the Viral Genome
2009
Icosahedral-tailed double-stranded DNA (dsDNA) bacteriophages and herpesviruses translocate viral DNA into a preformed procapsid in an ATP-driven reaction by a packaging complex that operates at a portal vertex. A similar packaging system operates in the tailless dsDNA phage PRD1 (Tectiviridae family), except that there is an internal membrane vesicle in the procapsid. The unit-length linear dsDNA genome with covalently linked 5'-terminal proteins enters the procapsid through a unique vertex. Two small integral membrane proteins, P20 and P22, provide a conduit for DNA translocation. The packaging machinery also contains the packaging ATPase P9 and the packaging efficiency factor P6. Here we…
Non-surgical periodontal treatment with a new ultrasonic device (Vectortm-ultrasonic system) or hand instruments. A prospective, controlled clinical …
2004
Objectives: The aim of this prospective, randomized, controlled clinical study was to compare the effectiveness of a newly developed ultrasonic device to that of scaling and root planing for non-surgical periodontal treatment. Material and Methods: Thirty-eight patients with moderate to advanced chronic periodontal disease were treated according to an “one-stage procedure” with either a newly developed ultrasonic device (VUS) (Vector™-ultrasonic system) or scaling and root planing (SRP) using hand instruments. Clinical assessments by plaque index (PlI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), gingival recession (GR), and clinical attachment level (CAL) were made …
Le vécu des sujets atteints de sclérose en plaques : modalités intersubjectives et conjugalité, stratégies adaptatives
