Cardiac tamponade with renal failure due to hemangioma of the heart.

In a 18 year-old woman, an isolated benign hemangioma of the right atrium led to cardiac tamponade and acute renal failure. After 8 days of anuria, the tumor was excised and replaced by a pericardial patch. The persistence of severe renal shutdown necessitated further hemodialysis during 22 days postoperatively. The patient was discharged on the 45th day in good hemodynamic and renal condition. Thirteen cases of benign hemangioma of the heart have been reported in the literature: 12 were found at autopsy; only 4 were complicated by hemopericardium but none of these survived.

[An indication for a permanent pacemaker : digitialis therapy for cardiac failure with disturbed atrioventricular conduction (author's transl)].

In twenty patients with advanced heart disease with severe cardiac failure and the presence of conduction disturbances before digitalis therapy, but in whom such disturbances were worsened or revealed by the treatment, it was necessary to insert a permanent pacemaker in order to make effective long term digitalisation possible without the risk of excessive bradycardia or pauses due to worsening of atrioventricular block. Six patients died within a period of 9 days to 34 months after insertion of the pacemaker, two were lost from sight, and the other 12 were followed-up regularly for an average period of 20 months, their condition remaining stationary and, in general, satisfactory.

Cytomegalovirus infection and graft survival in renal graft recipients.

We have studied 85 patients who received a renal transplant for CMV infection as well as for herpes simplex (HSV), herpes zoster (HZ), measles, mumps, rubella and hepatitis B. We found no evidence of primary or secondary infections for the non herpetic viruses except for hepatitis B infection that occurred in 17 per cent of the patients. CMV infection occurred in 87 per cent of the patients while antibody rises to HZ and HSV occurred in 30 and 13 per cent of the patients, respectively. The CMV infections occurred 2 to 4 months after the transplantation (mean time 11.1 weeks) and seemed to trigger the first episode of renal rejection that occurred earlier in the CMV infected group (mean time 12.1 weeks) than in the uninfected group (mean time 18.6 weeks). This difference in time is highly significant, p less than 0.001). However these CMV injections did not decrease the longterm survival of the grafted kidneys.

[Analysis of factors which can influence results of aortocoronary bypass surgery].

The various factors influencing the result of treatment have been studied in a series of 100 consecutive patients undergoing aorto-coronary bypass graft surgery. There were three operative deaths and twelve cases of post-operative infarction. Longterm, 85% of them were three year survivors, clinical improvement being maintained in 84% of them. Post-operative tests showed that 70% of patients have no pain on the maximal exercise test, but 48% had ischaemic depression of the ST segment. From among the 47 patients who had follow-up arteriography, 78% of the grafts were patent, but no improvement of the contractility of the left ventricle could be demonstrated (pre-operative ejection fraction 47 +/- 3%, post-operative 49+/- 3%). The pre-operative clinical features rarely give any indication of the prognosis. The same is true in the present series of the condition of the left ventricle, bearing in mind the fact that patients with grossly impaired ventricular contractility (ejection fraction below 30%) were routinely excluded from surgery. It is essentially the state of the coronary arterial network, as assessed by a score made up from the degree and number of stenoses, the quality of the distal bed, and the anatomical distribution, which will pick out those patients more at risk both from the surgery and from post-operative death and in whom the longterm result is likely to be disappointing with no improvement in function, with obstruction of the grafts, or with secondary death.

[Circadian rhythmus of the excretion of electrolytes and urinary proteins in rats].

Circadian rhythms in urinary water, sodium, potassium and proteins excretion are studied in 45 rats living alone in metabolism cages. Urines are collected during 4 consecutive 6 hours long periods during 2 consecutive days. Large circadian variations of these parameters (especially water and proteins excretion and urinary protein concentration) are described. The influence of feeding rhythms on the circadian urinary excretion rhythms is discussed. It is proposed that nightly renal hemodynamic changes (during meal digestion or with high renin plasma levels) can induce modifications in glomerular filtration rate and electrolytes and macromolecules transglomerular flow.

[Nycthemeral variations of blood and urine urea, creatinine and total proteins in rats].

The present study evidences blood and urine urea, creatinine and total proteins circadian variations in 50 male rats. Venous blood is sampled at behind socket sinus once a week at different hours (8, 11, 14, 17, 20, 23, 2 and 5) and urines are collected during 4 consecutive six hours periods in animals living in metabolism cages (8-14, 14-20, 20-2, 2-8). Blood three nitrogen substances circadian variations bring out the decrease at 17 h and increase at 23 or 2 h. Urinary excretion variations curves shows, in all cases, an increase more than 40% during the nightly periods. The influence of feeding rhythms on the blood and urine three derivates circadian rhythms is discussed. Moreover, night diuresis increase and urea and creatinine urinary remarkable constancy suggest water, solutes and macrosolutes transglomerular pathway nightly increase existence. Urea (+ 40%) and creatinine (+ 30%) clearance nightly significative increase confirms glomerular filtration circadian variations and its nightly increase.

[beta2-Microglobulin in renal transplanted patients (author's transl)].

Plasma beta2m has been measured frequently during long term follow-up of kidney transplanted outpatients. The ratio of beta2m/log creatinine was abnormally high in 15 patients of this series bearing a symptomatic hepatitis independently of any modification of immunodepressive drug administration schedule (azathioprine and corticoids). The true effect of azathioprine could not be isolated whereas corticotherapy modified clearly the beta2m/creatinine ratio : increase of dosage for rejection resulted in a fall of the ratio whereas fast reduction increased the ratio acting essentially on circulating beta2m level (12 cases). The beta2m/creatinine ratio was normal or occasionally diminished in the 22 patients having an uneventful clinical course. Six patients showed mixed effects of hepatitis and variation of corticoid dosage and 7 cases were too much intricated to permit a good analysis of the data.

Nine years' experience with internal arteriovenous fistulas for haemodialysis: a study of some factors influencing the results.

Data were collected concerning 314 internal arteriovenous fistulas created in 242 adult patients (92 women and 150 men). The immediate failure rate for the various techniques used ranged from 7-7 to 12-0 per cent, except for ulnar fistulas which had a rate of immediate thrombosis of 20-7 per cent. Survival rates were significantly lower for patients submitted to a combined therapy of dialysis and kidney transplantation when compared with patients treated with dialysis alone. The probability of survival of an arteriovenous fistula was lower in women than in men but the difference was significant only in patients undergoing transplantation. Survival rates at 2 years in dialysed patients were 87-6 per cent for distal radial-cephalic side-to-side fistulas, 100 per cent for radial-cephalic end-to-side fistulas located in the mid-forearm, 78-5 per cent for radial-cephalic end-to-side fistulas created near the wrist, 53-1 per cent for distal radial-cephalic end-to-end fistulas and 60-9 per cent for ulnar fistulas. Thrombosis was responsible for 87-2 per cent of 109 late failures. The incidence of infection was 1 case/11 patient years of haemodialysis.

Droperidol in acutely agitated patients. A double-blind placebo-controlled study.

Forty-one acutely agitated patients received an i.v. injection of 4 ml of a double blind solution containing either 10 mg of droperidol or placebo. The need for further medication (5 mg of haloperidol after 3 minutes or individually adapted psychotropics after 30 minutes) was used as a parameter for the evaluation of the results. Three minutes after the injection, haloperidol was needed by only six out of 19 patients of the droperidol group, but by 19 patients of the control group. Thirty minutes after the first injection, further medication was needed by only four droperidol patients and 10 placebo patients. No side effects could be attributed to the double blind medication.

Kidney graft rejection crisis: time-evolution, prognostic significance and role in infection.

For 255 kidney grafts performed during the past twelve years, 622 rejection crises (RC) were analysed. Irreversible RC occurred more frequently in second than in first grafts during the first post-operative trimester. A clear relationship between long term graft tolerance and RC occurring during the first post-operative month was observed. Infection was related to RC in 61% of cases. Infections following corticosteroid therapy after short intervals were usually characterised by a poor prognosis. These clinical features have practical implications for immunosuppressive treatment.

[Polycystic kidney treated by iterative hemodialysis and kidney transplantation. 25 cases].

Between January 1968 and December 1975, 25 patients (13 men and 12 women) were treated in the dialysis and transplantation unit of the Brugmann Hospital for terminal renal insufficiency secondary to polycystic disease. Nine patients (36%) underwent repeated surgery in order to ensure adequate successful vascular access for haemodialysis, whilst only 14.1% of patients suffering from renal insifficiency of another cause had to undergo operation on more than one occasion in order to be treated. In the majority of cases vasospasm was responsible for the obliteration of internal or external arterio-venous shunts. It was particularly common in women with a normal or low blood pressure. In this group, 3/4 of the patients needed several operations in order to make dialysis possible. Fourteen patients underwent bilateral nephrectomy. One death occurred in a patient who had received a renal transplant during the same operation. Fifteen kidney grafts were carried out and percentages of functional transplants at one and two years were 45.4 and 37.8% respectively. These poor results may be explained by the fact that 13 of our 15 patients were aged more than 40 years.
