ABSTRACT
OBJECTIVE: To investigate the prevalence and aetiology of bacteraemia following third molar extractions (B-TME), analysing the factors affecting its development. METHODS: The study group was formed of 100 patients undergoing third molar extractions under general anaesthesia. Peripheral venous blood samples were collected at baseline, 30 s after a mandibular third molar extraction and 15 min after completing the final extraction. Samples were inoculated into BACTEC aerobic and anaerobic blood culture bottles and were processed in the BacT/Alert. Subculture and further identification of the bacteria isolated was performed using conventional microbiological techniques. RESULTS: The prevalence of bacteraemia following third molar surgery was 62% at 30 s after the first dental extraction and 67% at 15 min after finishing the final extraction. The bacteria most frequently identified in the positive blood cultures were Streptococcus viridans (87.9%). CONCLUSION: In our series, the prevalence of B-TME at 30 s after a single third molar extraction was high, principally being of streptococcal aetiology, and was independent of the oral health status and the magnitude of the surgical procedure. Positive blood cultures persisted for at least 15 min after three to four dental extractions in a higher number of patients, questioning the supposedly transient nature of bacteraemia following dental extractions.

INTRODUCTION: Pseudomonas aeruginosa is usually the responsible agent for epidemics of folliculitis acquired in swimming pools and whirlpools. Sporadic cases of Pseudomonas folliculitis after epilation of the legs are well known by dermatologists, but unfrequently reported in the literature. CASE REPORT: We report the case of a 18-year-old female affected of folliculitis of the legs caused by Pseudomonas aeruginosa, after depilation. A meticulous investigation of contaminant sources was performed, and the responsible was the sponge used to wash the legs after depilation. DISCUSSION: Pseudomonas aeruginosa folliculitis after depilation is more frequent than usually reported. A meticulous study of the concomitant source of contamination is essential to avoid recurrent episodes.
