Nephrotic proteinuria with pre-eclampsia.

During a retrospective study of 100 patients who underwent renal biopsy because of pregnancy complicated by hypertension, we found 19 patients whom proteinuria exceeded 5.0 Gm. per 24 hours and an additional eight patients in whom excretion ranged between 3.5 and 5 Gm. per day. Of these 27 patients, 23 had the kidney lesion of pre-eclampsia, and three of them had superimposed hypertensive changes in the vasculature. The remaining four had other renal diseases. We located and re-examined 10 of the 23 pre-eclamptic women, 12 to 104 (mean, 36) months after delivery. Serum creatinine levels were normal in all but one, who was discovered to have polycystic kidney disease. During the same time period, we located the records of six women who had heavy proteinuria during gestation but were normotensive. Thus, at our institution, pre-eclampsia is the most common cause of the nephrotic syndrome in pregnancy. The frequency of nephrotic proteinuria in pre-eclampsia appears higher than previously suspected, but, despite this fact, recovery was complete in most instances.

The effect of respiratory motion on the echocardiogram.

The effects of respiratory movements on the ultrasonic echoes of the cardiac structures were recorded and analyzed in 50 consecutive patients. Deep inspiration in cooperative patients resulted in a considerable increase of dense anterior echoes, with blotting out of any distal or posterior echoes in 12 of 44 patients (group A). In the second or larger series (32 of 44 patients; group B), a posterior displacement of most of the identifiable intrinsic cardiac echoes was seen with deep inspiration, particularly those of the posterior wall of the left ventricle. Forced expiration produced an opposite or anterior displacement of the cardiac echoes. Normal respirations showed similar but smaller excursions.

Value of surface counting in predicting response to splenectomy in haemolytic anaemia.

The value of surface counting with (51)Cr-labelled red cells in predicting response to splenectomy in haemolytic anaemia has been analysed in 18 cases. The cases included six patients with congenital haemolytic anaemias, four with primary autoimmune haemolytic anaemias, and eight patients with secondary haemolytic anaemias (four with a positive antiglobulin test). All patients showed evidence of splenic accumulation of labelled cells and in 16 of the cases this was confined to the spleen. Improvement followed splenectomy in 17 of the cases although there was no close correlation between the magnitude of accumulation of radioactivity as measured by excess counts and the degree of response. The reasons for these discrepancies are discussed, The only patient who completely failed to respond to splenectomy had a sideroblastic element to the anaemia. It has been concluded that surface counting is of value in selecting patients for splenectomy but should not be depended upon without reference to other clinical and haematological factors, which are likely to influence the prognosis.
