title: Alpha-hemolytic streptococci: a major pathogen of iatrogenic meningitis following lumbar puncture. Case reports and a review of the literature.
abstract: Iatrogenic meningitis following lumbar puncture is a rare complication of myelography, spinal anesthesia, intrathecal chemotherapy, and epidural anesthesia. Sporadic cases and clusters of iatrogenic meningitis have been reported after intrathecal therapy, but most incidental cases are reported after myelography. Four cases of iatrogenic meningitis caused by viridans streptococci and a review of the literature are presented here. Observations and a case control study implicated a single anesthesiologist as the source. Probable cause of this cluster is non-observance of infection control measures as to the routine wearing of masks during the procedure. New infection control guidelines were implemented. A review of the literature on iatrogenic meningitis is given. Viridans streptococci have emerged as major pathogens of this complication. These findings underline the need to wear face masks since these bacteria are commensals of the oral cavity.
