BACKGROUND/AIMS The aim of the study was to investigate the clinical and microbiological effects of azithromycin as an adjunct to the non-surgical treatment of periodontitis in adults. Azithromycin is an antibiotic which is taken up by phagocytes and is released over long periods in inflamed tissue but requires a total of only three doses of 500 mg to(More)
Cryptococcus neoformans is an unconventional dimorphic fungus that can grow either as a yeast or in a filamentous form. To facilitate investigation of genetic factors important for its morphogenesis and pathogenicity, congenic a and α strains for a filamentous form were constructed. XL280 (α) was selected as the background strain because of its robust(More)
Since last reviewing the field, controlled release products have made the jump from research to clinical practice. The potential to extend the efficacy of periodontal therapy with such products is exciting, but also needs careful evaluation. This review will look at recent developments and also will examine the eventual place for these products in(More)
Sexual reproduction in an environmental pathogen helps maximize its lineage fitness to changing environment and the host. For the fungal pathogen Cryptococcus neoformans, sexual reproduction is proposed to have yielded hyper virulent and drug resistant variants. The life cycle of this pathogen commences with mating, followed by the yeast-hypha transition(More)
Azithromycin is an azalide antibiotic with excellent in vitro activity against a wide variety of oral bacteria. It has a long half-life, good tissue penetration and is preferentially taken up by phagocytes. We investigated the microbiological efficacy of azithromycin as an adjunct to the non-surgical treatment of adult chronic periodontitis; its clinical(More)
Controlled release devices containing tetracyclines or metronidazole are now commercially available for use in periodontal pockets. This review, in two parts, evaluates the evidence for and against using antibiotics in the treatment of periodontitis and considers the role for systemic and local delivery. Guidelines for antibiotic usage and recommended(More)
A study was carried out to demonstrate in an Irish population whether older persons at risk from pneumococcal disease would accept an offer of the pneumococcal vaccine at the same time as their influenza vaccination. Of the 450 patients from 2 practices invited to attend for vaccination, 367 (81.6%) accepted both vaccines, a further 17 (3.8%) accepted the(More)
The formation of new cementum is an important issue in clinical periodontology, as cementum is required to provide attachment for newly formed periodontal tissues to the root surface. In this study a model of cementogenesis in vitro was used in order to test the effects of root surface demineralization on the migration, attachment and formation of a(More)
A convergent route has been developed to synthesize an antifungal tricyclic o-hydroxy-p-quinone methide diterpenoid and analogues. A Li/naphthalene-mediated reductive alkylation was employed for coupling β-cyclocitral and the corresponding benzyl chloride, while a BBr3-mediated one-pot bis-demethylation and intramolecular Friedel-Crafts alkylation was used(More)
SofScale is a pre-scaling gel, containing disodium EDTA and sodium lauryl sulphate, which is claimed to soften calculus and therefore facilitate its removal. 31 subjects were treated in a double blind randomised placebo controlled split mouth study to evaluate this product. Test or placebo gels were applied to the lingual surfaces of the mandibular teeth(More)
