Predictive factors for oropharyngeal mycosis during radiochemotherapy for head and neck carcinoma and consequences on treatment duration. Results of mycosis in radiotherapy (MIR): a prospective longitudinal study.

Background And Purpose: Oropharyngeal mycosis (OPM) is a complication of radiotherapy (RT) treatments for head and neck (H&N) cancer, worsening mucositis and dysphagia, causing treatment interruptions and increasing overall treatment time. Prophylaxis with antifungals is expensive. Better patient selection through the analysis of prognostic factors should improve treatment efficacy and reduce costs.

DP7, a novel dihydropyridine multidrug resistance reverter, shows only weak inhibitory activity on human CYP3A enzyme(s).

The aim of this study was to investigate the effects of 3,5-dibenzoyl-4-(3-phenoxy-phenyl)-1,4-dihydro-2,6-dimethylpyridine (DP7), a novel multidrug resistance (MDR) reverter, on cytochrome P450 (CYP)-activities by human and rat liver microsomes. Effects of DP7 were assessed with use of selective substrates, markers of CYP activities. With rat microsomes, ethoxyresorufin (ETR) was used as substrate for CYP1A1, penthoxyresorufin (PTR) for 2B, benzyloxyresorufin (BZR) for 1A1/2, 2B, 2C, 3A.

[Community interventions among tobacco control strategies: coping with their definition and evaluation].

Community interventions represent a key component of the current anti-smoking strategies. We propose a conceptual framework for classifying these interventions, based on the concept of community utilised in different studies. We identified 5 different focuses: geographical areas (i.

[Effective laws for tobacco control: EU directives and Italian legislation].

Effective tobacco control policies include law issuing: bans/restrictions on smoking in public areas and workplaces, increasing of taxes on tobacco products, bans on advertising of tobacco products, warning labels on cigarette boxes. For some of these policies the European Union (EU) has introduced specific directives that EU member states have to put into law. This paper briefly presents literature data, EU directives and the laws consequently issued in Italy.
