Aim. To evaluate the efficacy of Brazilian green propolis in comparison to miconazole gel in the treatment of Candida-associated denture stomatitis. Methods. Forty-five denture stomatitis patients, with palatal mucosa erythema levels classified according to Newtons's criteria and with positive culture to Candida spp., were randomly divided into three treatment groups: 15 received miconazole gel 2%, 15 received propolis gel 2,5%, and 15 received propolis 24% for mouthwash. After four daily use lasting two weeks, they were reexamined for the denture stomatitis degree and for a second culture of Candida. The Wilcoxon's test was applied to compare the results of clinical classification of the denture stomatitis and the Candida spp. colonies numbers, before and after each treatment. The Kruskall-Wallis's test was used to compare efficacy among the three treatment groups. Results. There were a significant reduction or complete remission of denture stomatitis (P < 0.05)
and a significant decrease of Candida colonies for the three groups (P < 0.05).
There was no difference in the efficacy among the treatment groups (P > 0.05). Conclusion. Brazilian green propolis has a similar effect as miconazole in the treatment of Candida-associated denture stomatitis being an alternative in the therapeutics of this condition.
Osteolipoma is a rarely reported histologic variant of lipoma that exhibits bone formation. To the best of our knowledge, only 13 well-documented case reports of osteolipoma in the oral cavity have been published in the English literature. This study presents the clinical, radiographic, and histologic features of an osteolipoma in the oral cavity and reviews the pertinent literature. The patient was a 29-year-old female, who presented with an 8-month history of a painless, progressively enlarging, well-defined, movable submucosal mass in the left posterior buccal mucosa. The lesion had a hard consistency. Imaging findings revealed a spherical radiopacity with an irregular trabecular pattern. The lesion was excised and the diagnosis of osteolipoma was established. No recurrence was observed after a 5-year follow-up.
Impact of the organizational innovations in the performance of manufacture companies in Costa Rica and Germany. A case study. This investigation analyzes the direct and indirect impact produced by the organizational innovations implemented by the company. This study approaches the topic from a qualitative perspective through a case study analysis. Five study subjects were selected: three companies within an Industrial Corridor in Costa Rica and two companies from the federal state of Ba-den-Württemberg in Germany. As a result, the organizational innovation has a positive effect in the company's performance, and it was possible to identify both similarities and differences between countries and the implemented innovations. Another finding suggests that the firm's strategy plays a key role in defining future results of the organizational innovation. AbstrAct Esta investigación analiza el impacto directo e indirecto producido por las innovaciones organi-zacionales implementadas por las empresas manu-factureras en Costa Rica y Alemania. Este estudio abarca el tema desde una perspectiva cualitativa mediante un análisis de casos. Cinco compañías fueron seleccionadas: tres dentro de un corredor industrial en Costa Rica y dos compañías del es-tado federado de Baden-Wurtemberg en Alemania. Como resultado, la innovación organizacional tiene un efecto positivo en el desempeño de la empresa, y fue posible identificar similitudes y diferencias tanto entre los países como las innovaciones imple-mentadas. Otro hallazgo sugiere que la estrategia de la firma juega un papel importante en definir resultados futuros de la innovación organizacional. resumen Palabras clave: Innovación no tecnológica, innovación organizacional, desempeño empresarial, estudio de caso, industria manufacturera.
