Ultrasonography in the evaluation of wrist swelling in children.

We studied 15 children using high resolution ultrasonography. In all patients, ultrasound clearly demonstrated the nature of the soft tissue abnormality; 11/15 had thickening of the common synovial sheaths surrounding extensor tendons of the fingers, 1/15 had thickening of the flexor tendons and 3/15 had abnormalities consistent with ganglion cysts. These results indicate that ultrasound is an important yet noninvasive tool in the assessment of wrist swelling in children.

Comparison of techniques for examining long-term ECG recordings.

The Holter superimposition method was compared with the Argus/H computer system and the Stein/Peterson frozen display technique in the analysis of 94 long-term ambulatory ECG recordings using technical staff experienced with each analysis procedure. The use of the Holter superimposition method resulted in a failure of detection of 33-66 percent of ventricular and supraventricular arrhythmias as compared to the two other computer-based playback systems. The Argus/H system and the frozen display method of Stein and Peterson were comparable with respect to ventricular arrhythmia detection, but the frozen display method was superior to the Argus/H system with respect to the detection of supraventricular arrhythmias.
