Subarachnoid-pleural fistula. Case report and review of the literature.

A case is described of a subarachnoid-pleural fistula developing after resection of an intrathoracic benign nerve sheath tumor near the eleventh thoracic vertebra. The fistula was demonstrated by myelography and was corrected surgically. Of 12 previously reported cases, 11 occurred after trauma and one after an operation.

Flexible fiberoptic sigmoidoscopy--the Monroe Clinic experience. A prospective study of 5000 examinations.

Analysis of 5000 consecutive flexible fiberoptic sigmoidoscopies form the basis of this report. It is concluded that this method of examination of the distal large bowel is not only safe and comfortable for the patient but is a more appropriate examination than the rigid proctosigmoidoscopy because of the significant increase in pathologic material found. This examination has proven practical and acceptable in a multispecialty clinic setting and has completely replaced rigid proctosigmoidoscopy. Flexible sigmoidoscopy is now the standard "routine" examination of the rectum and distal colon. The rationale for this conclusion is presented in this timely report.
