We report an unusual case of rectal mesh erosion presenting 16 months after robotic sacrocolpopexy. The patient initially underwent a robotic sacrocolpopexy, lysis of adhesions, midurethral sling, and posterior colporrhaphy for symptomatic grade 2 pelvic organ prolapse and urodynamic stress incontinence. Her postoperative recovery was uneventful. Sixteen months later, an anterior 2 × 2-cm rectal mesh erosion was noted on the colonoscopy performed when she presented with hematochezia.

A study has been carried out in Haiti, involving 65 human subjects, mostly children, 39 of which had clinical symptoms of ribofiavin deficiency, in order to correlate clinical symptoms and erythrocyte glutathion reductase activity. Angular stomatitis was associated with overt biochemical deficiency in 25% of the cases examined and in most cases seemed to be related to other nutritional or infectious disorders.
