ABSTRACT
Spondylodiscitis is a common referral to spinal on call services. Identification of the causative organism is vital in order to dictate the appropriate antibiotic treatment. In this context, the surgical and interventional radiology team is often asked to perform a diagnostic biopsy. The aim of the present study was to assess whether the sampling location affects the diagnostic yield. Our results suggest that the overall positive diagnostic yield was 35%. When disc material was included in the sample the diagnostic yield significantly improved to 47%. Bone sampling alone had a positive yield of 15%. Age, pre-biopsy CRP, pre-biopsy use of antibiotics did not seem to affect the likelihood of obtaining a positive yield. These results suggests that when performing image guided biopsies for suspected cases of spondylodiscitis the inclusion of disc material is important.

Illness caused by hantaviruses is often severe and is typically characterized by diffuse pulmonary disease or renal insufficiency depending on the type of hantavirus. Here we report 2 cases of hantavirus infection that resulted in severe cognitive impairment but did not have any pulmonary or renal manifestations. These 2 cases may be indicative of previously underreported symptoms of hantavirus infection and might represent examples of hantavirus-related encephalopathy.
