[Left aorto-ventricular tunnel. Diagnosis with transthoracic and transesophageal echo-Doppler].

Aortic-left ventricular tunnel is an infrequent congenital heart lesion consisting of an abnormal tubular-shaped communication between the aortic root and the left ventricle that bypasses the aortic valve. It is clinically undistinguishable from aortic insufficiency. Its prompt and precise diagnosis is crucial since early surgical treatment is definitely indicated, in contrast to aortic insufficiency. In our case, two-dimensional and pulsed color-flow Doppler imaging established the diagnosis, and the transesophageal approach was a great aid in detecting the aortic opening with its turbulent diastolic flow, and in tracing its intramyocardial course. This paper may be of interest not just as a new case-report but insofar as it stresses how importantly the transthoracic and transesophageal echocardiographic and Doppler scanning contributes to its diagnosis and therapeutic indication.

Carbamazepine: an alternative drug for the treatment of nonhereditary chorea.

Five patients with a moderate to severe degree of nonhereditary chorea were successfully treated with standard anticonvulsant doses of carbamazepine. In two cases, the cause of chorea was related to a streptococcal infection. In another patient, the involuntary movements appeared seven days after severe head injury. The cause in the remaining two patients could not be determined with certainty, despite extensive laboratory investigations. Improvement began within four to 15 days after the initiation of therapy. No side effects were noticed in four patients throughout treatment (3 months to 36 months). In one patient, the medication had to be discontinued after 17 days, because of an allergic cutaneous rash. In view of our results, we propose that carbamazepine be considered as an alternative drug for the treatment of nonhereditary chorea.

[Pneumococci resistant to penicillin].

Between January of 1983 and December 1984, 11 strains of pneumococci resistant to penicillin were isolated, from a total of 46 strains studied with clinical signification, thus accounting for 23.9%. In nine cases (19.5%) pneumococci showed partial resistance to penicillin and in two strains (4.3%) resistance was total. Pneumococcal disease in our 11 patients was demonstrated by blood culture in 7 cases and by culture of the CSF, in 4. Diagnosis of the patients were as follows: 4 sepsis in immunosuppressed host, 2 bacteremia without an evident focus, 1 pneumonia, 3 meningitis and 1 ventriculitis. Vancomycin and rifampin are the most active in this cases. Some of the new cephalosporins of the third generation (cefotaxime and ceftriaxone) and cefuroxime have a good activity in vitro and a good passage to the CSF.
