Regression of cholesterol induced venous plaques after cholesterol withdrawal in rabbits.

Rabbits receiving a dietary cholesterol supplement of 0.5% develop atheromatous plaques in the systemic arteries, the pulmonary artery, the pulmonary veins and the venous cavities of the plexus pampiniformis in the funiculus spermaticus. Six months after the withdrawal of the cholesterol supplement the arterial lesions are still present, and show a fibrous transformation. This study is the first report of the total regression of the lesions in the particular venous localizations of the lungs and the plexus pampiniformis. The level of intraluminal pressure is discussed as the possible mechanism responsible for the diverging vascular reactivity.

Prospective comparison of T2-weighted fast spin-echo, with and without fat suppression, and conventional spin-echo pulse sequences in the upper abdomen.

PURPOSE: To evaluate use of fast spin-echo (FSE) magnetic resonance imaging with and without fat suppression in the liver and upper abdomen. MATERIALS AND METHODS: Conventional spin-echo (SE) T2-weighted, FSE T2-weighted, and fat-suppressed FSE T2-weighted images from 37 patients strongly suspected to have focal hepatic lesions were evaluated. RESULTS: Quantitative analysis demonstrated that fat-suppressed FSE imaging had the highest lesion-liver contrast-to-noise ratio; conventional SE imaging, the lowest. In a qualitative analysis, FSE imaging was preferred. In a rank order analysis, FSE imaging was preferred 83% of the time and fat-suppressed FSE imaging 17% of the time as regards overall image quality; fat-suppressed FSE imaging was preferred 64% of the time, FSE imaging 23% of the time, and conventional SE imaging 13% of the time as regards signal abnormality detection. CONCLUSION: FSE imaging with and without fat suppression is a potentially useful pulse sequence for evaluating the upper abdomen.

Second vertical osteotomy 15 years after initial operation.

A case of mandibular prognathism that existed 15 years after a previous attempt at correction has been presented. The initial procedure was the vertical osteotomy done via an extraoral approach. A second attempt at correction was undertaken with use of the same approach. The anatomic changes existing as a result of the first surgical procedure were of extreme interest. A decreased anteroposterior length of the sigmoid notch with posterior placement of the coronoid process was observed. Also, an increased thickness of the mandibular rami in a mediolateral plance was present. The clinical problems encountered as a result of these changes were difficulty in overlapping proximal and distal segments without definite osseous reductions and the inability to set back the mandible further without coronoidectomy. When these procedures were done, the patient's treatment was managed very successfully.

Management of orofacial infection in patients with chronic renal disease.

Chronic renal failure with resulting imbalance of electrolytes complicated the treatment of a patient with acute facial cellulitis that resulted from a carious molar. The patient's condition improved significantly after three days of hospitalization with meticulous medical and surgical care. He was able to return home after five days.
