Denture stomatitis (DS) is the most common oral fungal infection in denture wearers. Photodynamic inactivation (PDI) has been showing to be an effective technique in vivo against fungi, including fungal infections in the oral cavity. The disinfection of both oral mucosa and denture may represent a real advantage in terms of fungus control. This clinical study was designed to explore methylene blue (MB)-mediated PDI on oral mucosa and prosthesis of patients with DS. Subjects with DS were divided into two groups. One group received treatment based on the use of oral miconazole gel 2% (MIC). The other group received treatment by PDI using MB at 450 μg/mL and a diode laser (λ = 660 nm) with 100 mW and fluence of 28 J/cm2. Clinical outcome was evaluated regarding the degree of oral mucosa erythema and microbiological reduction of Candida spp. located in both palatal mucosa and prosthesis. Our results showed that PDI was significantly more effective than MIC in ameliorating inflammation after 15 days. Following 30 days, no statistically significant differences were observed between groups. Regarding the fungal burden, although the MIC group has presented more pronounced inactivation than PDI for both mucosa and prosthesis, no statistically significant differences were detected between them. This clinical study suggests that PDI can reduce fungal load and decrease the inflammation degree in patients with Candida-associated denture stomatitis.

Management system development to establish an alumini database: application to a nuclear institution
2007 - MOREIRA, FERNANDO J.F.; GUENA ANA M.O.; NAKAMURA, EMILIA K.; VIEIRA, MARTHA M.F.; DIAS, AILTON F.
To pursue the alumni professional evolution has been a long time aspiration. To solve this problem it was developed at IPEN - Nuclear and Energy Research Institute, with support from CNEN - National Nuclear Energy Commission, a system to collect data from graduate alumni. This system was introduced in 2006, during the 30 years celebration of the Nuclear Technology Graduate Program from IPEN, held in association with the University of São Paulo - USP. The main purpose is to follow the career development of the alumni, mainly those not employed in any of the institutes linked to CNEN. The developed system allowed the creation of a database comprising information about the academic degree, professional status and the extension of their contribution to the society. It allows also to follow if the knowledge obtained remained restrict to the Universities and Research Institutes or reached the private companies. The system allows several statistics to be done concerning not only the alumni but also the professors. In this work the first results of the data collection are presented, containing more than 750 responses from a total around 1340 alumni. The final purpose is to upgrade this system to collect data from the several institutes linked to CNEN, either graduate or undergraduate alumni.
