Abstract
Corynebacterium Jeikeium is a pathogen rarely involved in orthopaedic infections. Till date only 14 cases of osteomyelitis are described in the literature, envolving the tibia, foot and prosthethic (hip and joint) infection. To our knowledge, Corynebacterium Jeikeium as not been reported as an infectious agent of the spine. Our goal is to describe a case of scoliosis surgical site infection by a Corynebacterium Jeikeium specimen.
This is a retrospective and descriptive case report based on data from clinical records, patient observation and analysis of complementary exams.
We present a 24 year old female with a history of premature birth, West syndrome, spastic cerebral palsy and spina bifida. She was sent to our consult for evaluation of dorsolombar scoliosis. In October of 2014, she was submitted to surgery – posterior spine arthrodesis and instrumentation (D10 to L5) with bilateral pedicle screws and two chromium-cobalt bars. The early post-operative period was without complications. She was discharge at the seventh day of internment and was seen, fifteen days postoperative, at the consultation office, where the dressings were changed, with no signs of surgical site infection. One month post-operative, she recurs to the office because of an apparent seroma at the surgical site wound. There was no reference to fever or other signs of local/systemic infection. A swabbing of the wound was done and the patient was medicated with Ciprofloxacine, 500mg 12/12 hours – the culture came back negative. Seven days later she was seen again, maintaining the seroma with purge of a serous-aspect fluid. Antibiotic therapy was maintained and another swabbing was collected – culture came back negative. Because of suspected surgical site infection, she was re-operated at December of 2014. Surgical wound debridement was performed; three tissue samples and one exudate were sent to the microbiological department. In all samples but one was identified a Corynebacterium Jeikeium. No sensitivity test was performed. Intravenous Vancomicine, 1 gram 12/12 hours was started and maintained during 8 days. Eleven days post-operative she was discharged with oral Vibramicin, 100 milligrams 12/12 hours for two weeks. She is currently being followed at the doctor's office, with no sign of reinfection of the surgical site.
This is the first reported case describing an infection of the spine by a Corynebactereium Jeikeium. Isolation of the causative agent of infection and literature-based directed antibiotherapy are important for a successful outcome.
