Oral cavity infection: an adverse effect after the treatment of oral cancer in aged individuals.

Pan J, Zhao J, Jiang N - J Appl Oral Sci (2014 Jul-Aug)

Bottom Line: In this study, the oral cavity microorganisms such as bacteria and yeast were taken for the analysis.Here, we used antimicrobial agents which are common in clinical practice.The oxacillin resistance of S. aureus isolate confirms that the prevalence of MRSA is increasing in accordance to age-factor and immune compromise in elderly patients.

ABSTRACT

Objective: The immune compromised patients after treatment of oral cancer may have a chance of infection by drug-resistant opportunistic microbes. We investigated the occurrence of opportunistic microorganisms in aged individuals receiving follow-up examinations after treatment of oral cancer in China.

Material and methods: These patients were used as test group and the respective age grouped healthy individuals as control group. In this study, the oral cavity microorganisms such as bacteria and yeast were taken for the analysis. After the screening of representative microorganisms, their aptitude of pervasiveness against drugs was studied. Here, we used antimicrobial agents which are common in clinical practice. We also performed studies to investigate the presence of toxin genes in methicillin-resistant S. aureus (MRSA).

Results: The results indicate that the prevalence of drug-resistant microbes was more pronounced in oral cancer patients after initial treatment above 70 years old. The oxacillin resistance of S. aureus isolate confirms that the prevalence of MRSA is increasing in accordance to age-factor and immune compromise in elderly patients.

Conclusions: This study reveals the occurrence of drug-resistant opportunistic microorganisms in oral cavity after treatment for oral cancer in aged individuals. Special attention should be directed to MRSA during the treatment of oral cancer, and to realize the fact of immune compromise in elderly patients.

Mentions: The samples were collected from surgical scar, saliva, gingiva, and palate of 78elderly Chinese (43 cases of group I and 35 cases of group II). The majority ofidentified microorganisms were Candida, Staphylococcus andPseudomonas species. The graphical representation for thepercentage of species identification from one species in one isolates or two speciesin same isolates were presented in two sets of group I & II in each species(Figure 2). Statistical analysis revealed nosignificant difference between groups in the number of isolated microorganisms or thenumber of participants with these isolates.
