Gray-scale ultrasonography in the evaluation of neoplastic invasion of the base of the tongue.

Patients with primary carcinoma of the base of the tongue or direct invasion from contiguous areas were examined clinically and with ultrasound, and in some cases with computed tomography (CT), xerography, and polytomography. In all cases, multiple biopsy specimens were obtained. Utrasonography was better than the other imaging methods in delineating disease extent in the tongue itself, while CT and tomography were more useful in evaluating the retropharyngeal and lateral pharyngeal regions. It is suggested that ultrasound be used in the initial evaluation of such patients.

[Postoperative evaluation of Carpentier's mitral rings].

38 patients with Carpentier's ring inserted in the mitral position at surgery, are studied. The grade of the pre and postoperatory mitral murmur is correlated and compared with the radiographic size of the heart and left auricle as well as the pre and postoperatory angiocardiographic study. Only 3 (7'8%) of the 38 patients presented significant elevation of the pulmonary artery sistolic pressure together with important angiographic regurgitation. These three patients had to be operated on again, 60'52% did not present murmurs on these were grade I murmurs, while 76'32% did not present mitral reguritation. Only 8 of 14 patients with grade II sistole murmur in the postoperative period had grade II regurgitation. This no correlation was observed between the intensity of the murmur and the grade of angiocardiographic mitral regurgitation. We conclude that Carpentier's ring restores the mitral valve function to normal in the majority of cases and the angiocardiographic results are favorable.

[Clinical evaluation of amiodarone hydrochloride as an anti-arrhythmia agent].

15 patients with ventricular and supraventricular arrhythmias treated with Amiodarone hydrochloride via oral were studied. The results obtained show that in 86'6% of the cases the arrhythmia disappeared immediately, in 6'6% the arrhythmia disappeared late and in only one case the arrhythmia persisted. Statistical significance was found in the reduction of cardiac frequency as well as in the corrected QT interval for the frequency. The latter is an indirect consequence of the mode of action of the drug. The only side effect observed was the appearance of corneal opacification. It was demonstrated that this side effect is negligible when low doses which are equally effective are administered. The conclusion that Amiodarone is an excellent oral antiarrhythmic drug is reached. A daily dose of 400 mg during the first 20 days of each month with a rest of 10 days is recommended. In this way, the corneal opacification is minimal or nil. The possibility that the association of the drug with Quinidine could be effective in maintaining sinus rhythm post D.C. is suggested.

Liposarcoma of the stomach.

We present a case of gastric liposarcoma, a very uncommon pathology; only nine cases have been reported in the literature. We describe the radiologic findings of this neoplasm and emphasize the correlation between computed tomography (CT) and the macroscopic morphology of the tumor, which is conditioned by its histology. In our case, CT demonstration of fatty areas within the gastric mass facilitated the diagnosis. This finding has not been described for liposarcomas of the stomach.

[Angiocardiographic and clinical development of Carpentier's mitral rings].

Carpentier's ring was inserted in the mitral annulus of 79 patients suffering from mitral valve disease. 49 other patients also underwent surgery on other cardiac valves and are not considered in the present study. The mean follow up time was 19.5 months. The total hospital and late mortality in the isolated ring series was 3.8%. Clinical and hemodynamic improvement was evident postoperatively. The preoperative functional class (NYHA) of the patients was: I, 11.39%; II, 45.5%; III, 34.1%; IV, 8.86% respectively. The postoperative class was: I, 86.8%; II, 7.9%; III, 3.9%; and IV, 1.3% respectively. Postoperative hemodynamic and angiocardiographic evaluation was done in 27 patients. Mean pulmonary artery pressure fell from 49.8 +/- 2.4 mm. Hg to 38 +/- 2 mm. Hg. Mitral regurgitation present preoperatively in 66.6% of cases was present in residual form in only 18.5%. Atrial enlargement was moderate in 42.1% and severe in 57.9% before operation, and 80.3 moderate and 19.7 severe after operation. Tromboembolic accidents occurred in 2 patients (2.2%) both with severe atrial enlargement and atrial fibrillation pre and postoperatively. We conclude that Carpentier's ring is a valid alternative in the surgery of mitral valve disease.
