Head and neck infections in children due to Eikenella corrodens: Report of three cases and review of literature

INTRODUCTION

Eikenella corrodens is a small, nonmotile Gram-negative rod that is part of the normal flora in the mouth, upper respiratory, gastrointestinal, and genitourinary tracts. It is classically found in human bite (fist to mouth) infections but is also seen in respiratory tract and head and neck infections.

METHODS

We describe three cases of E. corrodens causing head and neck infections in children seen in our institution between 2013 and 2019. We also reviewed the available literature on pediatric head and neck infections caused by E. corrodens.

RESULTS

All 3 children recovered and fit the trends identified in the 58 patients published in the literature from 1976 to 2019.

CONCLUSIONS

E. corrodens is responsible for a range of head and neck infections in pediatric patients. It is a not infrequent cause of head and neck infections in children and should be considered when selecting presumptive antibiotic therapy.

Needle Licker’s Osteomyelitis Revisited: An Unusual Case of Vertebral Osteomyelitis withEikenella corrodensin a Diabetic Patient

Vertebral osteomyelitis due toEikenella corrodensis extremely rare. We report an unusual case of an infection caused byE. corrodensin a self-insulin-administering patient with diabetes. Similar to needle licker’s osteomyelitis, our case shows most likely the same pathomechanism and stresses the importance of correct insulin application.

Subcutaneous Eikenella corrodens, Actinomyces sp., and α-Hemolytic Streptococcus Abscess of the Thigh following a Vitamin B12 Injection

This case report describes a 38-year-old female presenting with a thigh abscess caused by Eikenella corrodens, Actinomyces sp., and α-hemolytic Streptococcus following an intramuscular vitamin B12 injection administered at an outpatient clinic. After failure to improve clinically with intravenous daptomycin and after visualization of the abscess with gas bubbles on CT scan, she was taken to the operating room for three separate surgical irrigation and debridement procedures. Treatment also included intravenous ampicillin/sulbactam followed by oral amoxicillin/clavulanic acid therapy. She remained symptom free and without infection at nine months following hospitalization. It was suspected that poor hygiene played a role in the infection, but a definitive cause was not identified.
