ABSTRACT
BACKGROUND: Clostridium perfringens septic arthritis of the sternoclavicular joint has not been reported previously. CASE REPORT: We present the case of a 70-year-old patient with a history of stage IV colon cancer who presented to the emergency department with chest and neck pain for 3 days. After assessment, he was discharged home on analgesics. Within 24 h he returned, critically ill with C. perfringens septic arthritis of the left sternoclavicular joint and septic shock. Why Should an Emergency Physician Be Aware of This? Emergency physicians should be aware of the possibility of C. perfringens sternoclavicular joint septic arthritis in patients with unexplained chest, shoulder, or neck pain, especially when associated with a history of colorectal carcinoma or immunosuppression. A finding of C. perfringens bacteremia should prompt a search for occult gastrointestinal malignancy.

Occult Hepatitis B infection (OBI), defined as the presence of serum HBV DNA without detectable HBsAg, can be classified into seropositive OBI [anti-HBc and/or anti-hepatitis B surface (anti- HBs) positive] and seronegative OBI (anti-HBc and anti- HBs negative). We examined the role of anti-HBc as a screening test for OBI in HCV patients with chronic liver diseases and evaluated the possible impact of OBI on liver disease progression. 90 patients with hepatitis C related chronic liver diseases (CLD) and negative for HBsAg were divided into three equal groups; chronic hepatitis, liver cirrhosis and hepatocellular carcinoma (HCC). Patients were tested for anti-HBc by ELISA and by PCR for S-gene. Total anti-HBc was found in 26 patients (28.9%). 8 patients (8.9%) had positive serum HBV DNA. Of these, 2 were positive for anti-HBc and 6 negative for anti-HBc. No correlation between OBI and severity of HCV related CLD was observed. In conclusion, as OBI was not associated with total anti-HBc, it is invaluable surrogate marker for OBI detection.
