RESUMO

The quantification of ten microorganisms at the root ends and in the surrounding periradicular lesions was performed. Thirty 3 mm samples root ends and 30 samples of the surrounding chronic periapical infection were collected during apical microsurgery. Samples were triturated, and the bacterial DNA was obtained. The bacterial quantification was performed by using the SYBR Green system. At least one microorganism was detected in all patients. In both the root end and periapical samples, Fusobacterium nucleatum (71.6%), Dialister pneumosintes (58.3%) and Tannerella forsythia (48.3%) were the most prevalent species. Dialister pneumosintes showed statistically significant values in the root end, and F. nucleatum was also significant in the apical periodontitis samples. A statistically significant association between T. forsythia and Porphyromonas gingivalis in the root ends was observed. Bacterial associations from 2 to 7 species were observed in most samples. Extra-radicular and/or intra-radicular infections were present in all teeth with failed endodontic treatment, and showed polymicrobial infection in most cases, with a predominance of F. nucleatum, D. pneumosintes and T. forsythia. When present, Enterococcus faecalis was never found to be the most prevalent species. The presence of a microbial diversity in post-treatment apical periodontitis confirms the polymicrobial and synergistic characteristic of this process. Our results show that the bacterial array associated with the 3 mm root ends and periradicular lesions in post-treatment apical periodontitis are complex and with a high inter-individual variability. These results might be useful to delineate treatment strategies for microbial elimination in apical periodontitis. Further studies are necessary to elucidate the role of these microorganisms in endodontic treatment failures.

RESUMO

Gastric lipoma is considered a rare condition that may constitute a challenging diagnosis. A 51-year-old woman presented dysphagia and abdominal pain, and an upper digestive endoscopic study disclosed a gastric tumor located in the submucosa of the pyloric antrum. Conclusive diagnosis was established after repeated endoscopic biopsies, and the patient was subjected to an atypical gastrectomy, which evolved into a pyloric stenosis. This complication was appropriately corrected and the patient remains symptomless, under outpatient surveillance.

RESUMO

Os autores apresentam uma paciente de 47 anos, portadora de tumor maligno na regiao deltoide esquerda, operada ha oito meses, apresentando recidiva local. Foi reoperada visando a retirada total do tumor sendo efetuada quimio e radioterapia adjuvantes.Consideram finalmente a possibilidade de um fator imunologico haver contribuido para a boa evolucao do caso mencionado pelos autores
