A case of systemic inflammatory response syndrome caused by pericoronitis of a wisdom tooth due to multidrug resistant Pseudomonas aeruginosa infection

Abstract

We report a case of systemic inflammatory response syndrome (SIRS) caused by multidrug resistant Pseudomonas aeruginosa (MDRP) infection during anti-leukemia chemotherapy. The origin of the infection was suspected because of third molar pericoronitis. A 25-year-old man presented with a chief complaint of right mandibular molar pain. His general condition then rapidly deteriorated. Subsequently, MDRP was detected by both blood culture and swabbing the gingival sulcus exudates in regions surrounding the infected third molar. In this patient, polymyxin B was administered by intravenous injection because of drug susceptibility. The patient was subsequently underwent right mandibular third molar extraction after a good recovery.
