Fluoroscopy Dose and Time Characteristics During Endoscopic Retrograde Cholangiopancreatography (ERCP).

Radiation exposure during endoscopic retrograde cholangiopancreatography is known, however, data in relation to radiation usage is unclear. We evaluate radiation exposure using fluoroscopy dose (FD) and time (FT). A prospective analysis of 197 patients undergoing endoscopic retrograde cholangiopancreatography was completed.

Ocular Radiation Threshold Projection Based off of Fluoroscopy Time During ERCP.

Objectives: Current international guidelines for ocular radiation exposure suggest a threshold of 20 millisieverts (mSv)/year. Although endoscopists wear lead aprons, use of protective eye wear is optional. This study was conducted to analyze the lens radiation exposure during endoscopic retrograde cholangiopancreatography (ERCP) for endoscopists to determine the time of fluoroscopy needed to warrant using lens protection during ERCP.

Elevation of tumor necrosis factor-alpha in cerebrospinal fluid of autistic children.

Recent reports implicating elevated cytokines in the central nervous system in a small number of patients studied with autism have reported clinical regression. These studies have not focused on tumor necrosis factor-alpha as a possible marker for inflammatory damage. A series of 10 children with autism had clinical evaluation of their serum and spinal fluid for inflammatory changes and possible metabolic disease as part of their neurological evaluation.
