Defecatory complications are common after spinal cord injury (SCI) and have been attributed, in part, to an imbalance of the autonomic nervous system between parasympathetic and sympathetic effects on the colon. Because parasympathetic (i.e., cholinergic) input to the bowel may be downregulated after SCI, it was hypothesized that neostigmine, a medication that increases cholinergic tone by blocking the metabolism of acetylcholine, might promote bowel evacuation in these persons. Since neostigmine is known to cause bradycardia and bronchoconstriction, we also assessed whether these side-effects could be prevented by coadministration of neostigmine with glycopyrrolate, an anticholinergic agent that has limited activity on the muscarinic receptors of the colon. The hypothesis was tested in 13 persons with SCI in whom videofluoroscopy was carried out after instillation of a barium oatmeal paste into the rectum and descending colon. On separate days, subjects received, in a randomized, blinded design, one of three intravenous infusates (normal saline, 2 mg neostigmine, or 2 mg neostigmine + 0.4 mg glycopyrrolate). The effect of these infusates on bowel evacuation of the barium paste, heart rate, and airway resistance was determined. Both neostigmine and neostigmine + glycopyrrolate resulted in prompt bowel evacuation. The nadir heart rate was lower after neostigmine alone than with the combination. Neostigmine administration increased both total and central airway resistance, an effect that was not observed with the coadministration of glycopyrrolate. Other side-effects of neostigmine and the combination of drugs included muscle fasciculations and dry mouth, both of which were mild and short-lived. Abdominal cramping was noted in subjects with spinal cord lesions below thoracic level 10. These results indicated that neostigmine/glycopyrrolate administration is safe and well tolerated in persons with chronic SCI.

We report a case of severe dysphagia in a 29-yr-old woman with cerebral palsy after she was injected with botulinum toxin B to her lower limbs and lumbar paraspinal muscles. Four days after the treatment, she developed difficulty swallowing, more severe for solid foods than for liquids, accompanied by dry mouth, blurred vision, and voice hoarseness. Fifteen days after the injection, with worsening of her dysphagia, she was hospitalized. A laryngoscopic evaluation revealed bilateral vocal cord paresis, and a modified barium swallow test demonstrated delayed oral initiation, upper airway penetration, and no reflexive cough. In the following days, she improved spontaneously and was discharged 12 days later when she re-acquired the ability to swallow solid foods. Her symptoms resolved completely only 75 days after the injection. Although dysphagia is a common side effect of botulinum injection in the neck, to our knowledge, this is the first reported case of severe dysphagia after injection in a distant anatomic site.
