The clinical presentation of intervertebral disc, facet joint, nerve root, and sacroiliac (SI) joint diseases are often indistinguishable. SI joint arthritis likely accounts for a significant proportion of what is called "low-back pain" or "sciatica." Our goal was to determine the incidence of SI joint arthritis in patients with this presentation. ⋯ There is a relatively high incidence of SI joint arthritis in patients undergoing evaluation for "low-back pain" or "sciatica." Hence, SI joint arthritis should be considered a possible diagnosis in these patients.

Apheresis is an important technique, used increasingly for a variety of conditions. It is sometimes performed via peripheral access because of concern over major complications associated with central venous catheter (CVC) placement. This study was to determine the safety and success of radiologic placement of CVCs for apheresis. ⋯ CVCs are safe for apheresis if real-time sonographic guidance is used for the puncture, guide wire and catheter placement are confirmed fluoroscopically, and the duration of catheterization is short.

Comparative Study
Comparison of digital angiographic images with conventional radiographs for detection of pneumothorax after needle biopsy of lung.
To compare the rate of detection of pneumothoraces from images obtained from a digital angiographic system (1024 x 1024 matrix) and from conventional film-screen chest radiographs, following fine-needle biopsy of the lung. ⋯ The detection of pneumothorax from digital images was far inferior to that from standard film-screen chest radiographs. Therefore, standard chest radiographs are recommended after fine-needle biopsy of the lung.
