Prevotella osteomyelitis after dental capping procedure

Abstract

We present a 49 year old man who presented to the emergency department with severe lower back pain of 5 days duration. One week prior he had been diagnosed with a right psoas muscle abscess and was discharged with a 28 day course of moxifloxacin after the preliminary culture from the psoas grew an anaerobic organism. MRI of the lumbar spine showed marrow edema in the L2 body, occupying most of the anterior two thirds of the body, with cortical erosion at the anteroinferior aspect of L1. Blood cultures were negative and bone biopsy of L2 showed neutrophilic invasion and reactive changes. Cultures grew Prevotella oralis. Hematogenous spread from a composite bonding procedure for exposed teeth roots is thought to be the source for the vertebral osteomyelitis. This is a plausible spread of infection in our case because it was thought that the osteomyelitis occurred first and spread to the psoas muscle.

Erosion of the sella turcica and pituitary expansion secondary to polymicrobial brain abscesses: a case report

“…and Prevotella spp. has been reported earlier, this marks the first description of skull base erosion with concomitant enlargement of pituitary gland secondary to a polymicrobial infection [4][5][6][7]. Here, we present this unique case along with a brief review of the pertinent literature.…”

“… Prevotella spp. are anaerobic Gram-negative bacilli commonly identified in oral, vaginal, and gut microbiota and a known culprit causing BA in patients with a history of dental procedures [6, 15, 16]. Corynebacterium spp.…”

Septic Embolism Associated With Periodontal Disease: A Case Report

“…Regarding Provetella oralis , a gram-negative anaerobic bacteria, fluroquinolones are often used, but increasing resistance has been documented. With rising resistance to fluoroquinolones by Provetella oralis , clinicians should be aware of clinical failure in patients taking these antimicrobials and switch to meropenem, another considered regimen for this agent [ 1 , 12 ].…”

Secondary anaerobic infection in a case of multidrug resistant tubercular paraspinal abscess: A rare presentation

“…Anaerobic organisms have been reported rarely and among them, the most common are the Streptococcus species. Apart from this, there are two case reports by Parvimonas micra , two by Prevotella species, one case report by Fusobacterium, Bacteroides and Propionibacterium each [10–14]. In all these anaerobic infections of psoas abscess, some or the other underlying cause have been reported are dental cavity, malignancy, muscle trauma, history of past surgery, decubitus ulcer and even diabetes mellitus.…”
