Renal function after nephrectomy for donor organs.

Thirty-three living related kidney donors were investigated at a mean of 5.8 years after donor nephrectomy (range 3-18 years) to detect late adverse effects. They were evaluated for hypertension, the presence of proteinuria and renal dysfunction as assessed by serum creatinine value and creatinine clearance. There was a significant rise in both diastolic blood pressure and serum creatinine levels and a trend towards significance in the decline in creatinine clearance. Eleven individuals had diastolic blood pressure greater than or equal to 90 mmHg but only 1 required treatment. Although the rise in serum creatinine reached significance the mean serum creatinine (104.91 mumol/l) remained within the normal range. Two patients showed a minimal rise in proteinuria. The overall results confirm that kidney donation is safe and indicate that there are no significant late sequelae.

[Value of echocardiography in the diagnosis of myxoma of the left auricle].

We have been able to differentiate the right pre-operatory diagnosis of mixoma in the left auricle versus "tumor" caused by hypertrophy and fusion of the papillary muscles of the left ventricle in a severe mitral stenosis. In the mixoma we find the echoes only in the ventricular diastole and not in the sistole; there is a place without echoes in the protodiastole--which has a diagnosis value, and sometimes in the telediastole. When it is a "tumor" in the fusioned papillary muscles of the left ventricle, echoes can be found in ventricular diastole and sistole and there are not spaces without echoes in the protodiastole as it is usual in the pedicled tumors of the left auricle. We have found a new sign to predict the existence of a tumor in the left auricle instead of a mitral stenosis; if we find echoes in the left auricle during the ventricular sistole, we will observe that the front edges of the waves form a capital W, and the back ones form a small w. In the central portions of both ws, the waves go forward as it should happen in the mitral valve when existing a real mitral stenosis. Nevertheless, as this central portion is surrounded by a space without echoes, it means that the tumor is a pedicled one, constitutes an obstruction and is causing similar signs to those pertaining to the mitral stenosis.
