The authors report two cases of sulfadiazine-induced obstructive nephropathy that were diagnosed with ultrasound (US). Renal US demonstrated layered clusters of echogenic shadowing material--presumed to be sulfa crystals--which cleared when the crystalluria resolved. The authors conclude that renal US is helpful in diagnosing sulfa calculi and subsequent obstructive nephropathy. 相似文献

Endoscopy is commonly accepted as the gold standard in the evaluation of neoplastic colonic disease. The procedure is used to confirm or exclude lesions detected on barium enemas, with the assumption that the endoscopist was successful in reaching the appropriate segment of the colon. We collected 18 cases, all with proved colonic neoplasm 2-8 cm in diameter that were detected by barium enema but overlooked on initial endoscopy. All of the lesions were relatively flat with little intraluminal protuberance. Histologic examination showed malignant foci in six of 11 tumors that were resected. In two of the other seven patients, unresected lesions progressed to advanced carcinomas. This experience suggests that a repeat barium enema is indicated when endoscopy fails to detect a colonic tumor suspected on barium enema examination. 相似文献

Current methods of teaching cataract surgery include lectures, wet-lab sessions, and participation in real surgery. We describe a new method using a microendoscopic cyclophotocoagulation device during phacoemulsification cataract extraction and posterior chamber intraocular lens (IOL) implantation in 4 eyes of 4 patients. Endoscopic visualization during surgery aided in construction of the corneal incision, location of the capsulorhexis edge, and estimation of the lens groove depth. It also demonstrated clinical findings not observable with the surgical microscope such as misplaced IOL haptics and residual lens cortex. Use of the endoscope enhanced the educational value of the surgery and the final surgical outcome. 相似文献

OBJECTIVE: The objective of this study was to determine the value of early (< 6 months) duplex scanning after carotid endarterectomy (CEA) with an intraoperative completion study with normal results. Attention was paid to restenosis rates and reoperation for recurrent stenosis within the first 6 months. METHODS: A retrospective review was performed on 380 CEAs (338 patients) with intraoperative completion studies and duplex surveillance within the first 6 months. Results of completion studies, restenosis rates, and recurrent symptoms were evaluated for each operation. Studies were performed from 0 to 200 days postoperatively (median, 28). RESULTS: Intraoperative completion studies included 333 angiograms, 26 duplex scans, and 21 angiograms with duplex scans. Of the 380 intraoperative completion studies, 28 (7.5%) had abnormal findings, including 14 abnormal internal carotid arteries (ICAs). Twenty-four procedures were revised, and the findings of all repeat completion studies were normal. Of the initial completion studies, in four cases, abnormalities (3 ICAs) were insignificant and did not warrant further intervention. Follow-up ICA duplex scans had normal results after 364 (95.8%) CEAs. There were 14 mild recurrent ICA stenoses and two moderate recurrent ICA stenoses; neither had abnormal findings from the completion study. There were no severe recurrent ICA stenoses. External carotid artery (ECA) recurrent stenosis included 7 mild, 15 moderate, and 9 severe restenoses. CONCLUSIONS: Only 0.5% of CEAs developed moderate restenosis. No procedures had severe recurrent stenosis on duplex scan within the first 6 months, and none required intervention. Duplex surveillance in the first 6 months is relatively unproductive, providing that there were normal results from an intraoperative completion study for each patient. Routine surveillance can be started at 1 year. 相似文献

Hemorrhagic colitis due to Escherichia coli O157:H7 is a distinct clinical entity characterized by abdominal pain, watery diarrhea progressing to bloody diarrhea, and little or no fever. It has been reported to have a mortality as high as 31%. This form of colitis is not described in the radiologic literature. This paper describes the radiographic findings, and stresses the need for radiologists to be familiar with the disease in order to assist in early diagnosis. Key clinical and epidemiological features are reviewed. 相似文献

Small bowel involvement in rheumatoid arthritis is rare and is caused by vasculitis, which results in ulceration, perforation, and necrosis of the small bowel. The authors present a case of rheumatoid vasculitis associated with a small bowel stricture. The patient had a 3-week history of daily postprandial bloating, abdominal cramping, and vomiting. Barium study demonstrated partial small bowel obstruction. Pathologic examination of a resected segment of the small bowel proved that the stricture was caused by rheumatoid vasculitis. To the authors' knowledge, this is the first reported case of such an association in the radiology literature. 相似文献

Esophageal intramural hematoma can mimic other causes of chest pain. When the patient is known to have coronary artery disease, the diagnosis may be difficult. Moreover, the course may be complicated and may harm the patient if antiplatelet drugs, thrombolytics, and anticoagulants are used. The presence of odynophagia should alert the clinician to the possibility of an esophageal origin, even in a patient with known coronary artery disease. We present a case in which early recognition of the clinical presentation prevented potential iatrogenic complications. 相似文献
