ABSTRACT
Intestinal volvulus in patients with Crohn's disease is rare and we could find only one report of sigmoid volvulus with active Crohn's colitis. We have seen a 54-year-old woman with long-standing Crohn's disease who developed large-bowel obstruction. After eventual detorsion of the sigmoid volvulus, we found that her ileum was involved with active Crohn's disease and that her colonic mucosa was free of mucosal lesions. In this case, we suspect that the reactivation of the ileal Crohn's disease as well as other features commonly associated with Crohn's disease contributed to the development of sigmoid volvulus by causing fixation, torsion, and dilatation of distal bowel.

Interpretation of electroglottography (EGG) as an index of glottal contact area has been complicated by difficulty obtaining independent validation measures. The purpose of this research was to implement a new simultaneous EGG/videostroboscopic technique for the evaluation of the relationship between a discontinuity in the opening phase of the EGG waveform with the onset of glottal opening viewed via videostroboscopy. The results support previous suggestions that this EGG discontinuity, when observed in nonpathologic individuals, usually marks the onset of glottal opening along the superior surface of the vocal folds.
