RESUMO
BACKGROUND: Capsule endoscopy (CE) is increasingly used in patients with suspected or known Crohn's disease (CD). OBJECTIVE: To determine the diagnostic yield of CE and the distribution of small-bowel (SB) lesions in symptomatic patients with known CD. DESIGN AND SETTING: Retrospective review of CE procedures performed in patients with CD between 2001 and 2005 in a tertiary care center. PATIENTS: One hundred thirty-four patients with an established diagnosis of CD and symptoms suggestive of active disease. INTERVENTIONS: Swallowing the capsule. MAIN OUTCOME MEASUREMENTS: Diagnostic yield of CE and distribution of SB lesions in patients with CD. RESULTS: One hundred forty-six CE procedures were performed on 134 CD patients. Fifty-two (39%) of 134 patients had CE findings diagnostic of active CD (> 3 ulcerations), and 17 (13%) had findings suggestive of active CD (< or = 3 ulcerations). Fifty-seven (42%) patients had normal findings, and 6% had normal but incomplete studies. The distribution of SB lesions was 32% in the duodenum, 53% in the jejunum, 67% in the proximal ileum, and 85% in the distal ileum. CE was comparable to ileoscopy in detecting ileal ulcerations (55% vs 48%), but superior to SB follow-through in detecting CD lesions in the SB (incremental yield of 32%; 95% CI, 9%-54%; P = .0017). LIMITATIONS: Retrospective study from a single center. CONCLUSIONS: CE identified SB lesions in approximately half of symptomatic CD patients. Large-scale prospective studies are needed to evaluate whether positive CE findings may affect disease outcomes.

The association between Down syndrome and gastrointestinal anomalies such as duodenal and esophageal atresia, tracheoesophageal fistulas, and Hirschsprung's disease is well documented. More recently, an association between Down syndrome and achalasia was reported. In this report, we describe a 48-year-old woman with a history of Down syndrome who presented with dysphagia. Work-up of the dysphagia showed not only achalasia but also a duodenal duplication. To our knowledge, there have been no reports of Down syndrome associated with duodenal duplication. Whether this finding is simply a coincidence or whether duodenal duplication is associated with Down syndrome will need to be determined with future studies.

A 35-year-old woman with a history of indeterminate colitis developed symptoms of multiple sclerosis after treatment with infliximab. Neurologic examination confirmed upper and lower extremity motor and sensory deficits. MRI showed multiple enhancing white matter lesions distributed throughout her brain as well as her thoracic spine. There may be a link between inflammatory demyelinating disease of the central nervous system and anti-tumor necrosis-alpha therapy. This case report describes the onset or worsening of a demyelinating process after the initiation of infliximab therapy in a patient with indeterminate colitis.
