Two hundred and forty-two elderly patients (> 65 years) with acute renal failure (ARF) treated at a predominantly medical intensive care unit between 1975 and 1990 were retrospectively analyzed for underlying diseases, severity of disease (as evaluated by the rate of ventilated patients, septicemia and APACHE II score, respectively), causes of ARF, acute and chronic risk factors for the development of ARF, complications during treatment and outcome. Overall mortality was 61%; 28 patients (12%) died in spite of resolution of ARF so actually, 49% of the patients died in ARF. Outcome was comparable to other age groups with overall mortality being 57% in patients < 18 years and 59% in those 19-65 years. Moreover, within the group of elderlies mortality did not increase with age and was 60% in those aged 65-68 and 54% in those aged > 80 years, respectively. The need for renal replacement therapy, plasma creatinine > 6 mg/dl, anuria, BUN > 120 mg/dl, ventilator dependency and the presence of septicemia all negatively affected outcome. During the years 1975 to 1990 mortality decreased from > 70% to < 50% (p < 0.02). This improvement of survival was seen in spite of an increase in the severity of disease (1975-1982: 20% ventilated patients, 24% with septicemia, 1983-1990 51% and 40%, respectively, p < 0.01). We conclude that age per se is not an important determinant of survival in patients with ARF and that prognosis has improved considerably during the last 15 years and this was seen in spite of an increase in the severity of disease. It is not justified to withhold therapy in elderly patients acquiring ARF.

A method to provide left ventricular circulatory assistance without thoracotomy was developed and implemented in 2 patients. The left atrium is cannulated from the neck by passing a catheter across the interatrial septum (Dennis technique) using fluoroscopic and echocardiographic imaging. To facilitate ambulation, the arterial catheter is connected to the right axillary artery. Left atrial to axillary arterial flow is produced by a centrifugal pump. Two patients were perfused at 2.7 to 3.5 L/min for 5 and 6.5 days. One patient had successful coronary angioplasty during perfusion and remains alive 1 year later. The other patient died of sepsis and anuria that preceded implementation of circulatory assistance. The Dennis method of continuous left ventricular circulatory assistance avoids thoracotomy, requires a minimal operation, is portable and inexpensive, uses widely available equipment, and is particularly suitable for patients in cardiogenic shock after acute myocardial infarction. The method is safe and cost-effective, and merits wider application in selected patients.

Over a 28-year period, 113 out of 2986 (3.8%) patients dialysed for acute renal failure at a referral center in North India were diagnosed to have acute renal cortical necrosis (ACN). Obstetric causes were responsible for ACN in 56.6% patients and nonobstetric causes in 43.4%. Within the obstetric group, ACN developed in association with complications of late pregnancy in 37.1% and following septic abortion in 19.5%. The various nonobstetric causes included viperine snake bite in 14.2%, hemolytic uremic syndrome in 11.5%, renal allograft rejection in 5.3%, acute gastroenteritis in 4.4%, acute pancreatitis in 3.5%, septicemia in 2.7%, and trauma and drug-induced IV hemolysis in 0.9% patients. Total anuria was the commonest presenting feature and was noted in 78.8% of patients. Renal histology showed diffuse cortical necrosis in 62.8% and patchy lesions in 37.2% patients. Computerized tomography (CT scan) of the kidneys revealed characteristic diagnostic findings in all the 5 patients in whom it was done. Dialytic support could be withdrawn as a result of improvement in renal function in 19 patients with patchy cortical necrosis. Dialysis-free survival of as long as 12 years has been recorded. The present study shows that, in contrast to the Western world, ACN continues to be a common cause of acute renal failure in developing countries. CT scan of the kidneys is helpful in establishing an early diagnosis.

Ninety patients with esophageal perforations were operated on at our institutions between 1970 and 1992. Thirty-four of them were seen after delayed diagnosis (> 24 hours) with mediastinal sepsis caused by perforation of the thoracic esophagus. There were 18 patients with spontaneous ruptures, 11 with instrumental perforations (including one caused during laparotomy), and 3 perforations caused by foreign bodies. One patient had perforation of an esophageal ulcer into the pericardium and another had perforation of an esophageal diverticulum into the mediastinum. Nineteen patients underwent primary repair of the perforation with cleansing and drainage of the mediastinum and the pleural cavity. The remaining 15 had primary extirpation of the thoracic esophagus, irrigation of the mediastinum with antibiotics, cervical esophagostomy, gastrostomy, and drainage of the mediastinum and pleural cavity. Nineteen of the 34 patients survived (hospital mortality 44%). Of patients with primary repair, only six survived (in-hospital mortality 68%), whereas only two patients treated with esophagectomy died (in-hospital mortality 13%). The difference was highly significant (p = 0.001). The most common cause of death was multiorgan failure resulting from sepsis. Postoperative complications developed in four patients treated with primary repair (two sepsis, one empyema, and one anuria) and in seven patients treated with esophagectomy (two empyema, two sepsis, one pneumonia, one mediastinal abscess, and one brain abscess). After healing of the mediastinitis, the esophagogastric continuity was reconstructed with colon in 11 patients and stomach in two patients. In the management of delayed esophageal perforation with mediastinal sepsis, esophagectomy is superior to primary repair alone, which often leads to mediastinal leakage, continued sepsis, and death.

One hundred and twenty patients with a mean age of 38 years (range 12-85 years; M 91, F 37) were studied over a period of 5 years in a teaching hospital in Dhaka. Sixty-two patients presented with probable anuria with 1-4 days' duration, 63 patients presented with oliguria, and 3 were nonoliguric. The causes of acute renal failure were medical (94), surgical (22), obstetrical (13). Of the medical cases, the causes were gastroenteritis in 42 cases, gastroenteritis with CNS involvement in 11 cases, rapidly progressive glomerulonephritis in 10 cases, acute viral hepatitis in 8 cases, and septicemia in 8 cases. Of 22 surgical cases, postoperative acute renal failure was the cause in 9, road traffic accident in 6, and renal calculus disease in 7. There were 13 cases in the obstetrics group, of whom 9 were due to abortion, 2 were due to preeclampsia, and the other 2 were postoperative. The mean blood urea of all cases was 35 mmol/L and serum creatinine was 988 mumol/L. Dialysis was required in 105 cases; of these, 72 were medical cases, 21 were surgical cases, and 12 were obstetric cases. The overall survival rate was 75%. The improved survival is probably due to timely referral and prompt medical management.

Massive hemolysis and renal failure are rare complications of infection with Clostridium perfringens, resulting in a very high mortality rate (70-100%). The severity of the infection depends on the presence of underlying conditions such as malignancies and diabetes mellitus. In patients without underlying disorders, massive hemolysis and anuria have been observed in only eight cases, according to recent reports. This case report describes a 61-year-old man who died of C. perfringens septicemia with massive hemolysis and anuria less than 4 h after admittance to the hospital, despite rapid and adequate antibiotic treatment. No focal infection was found.

We report on a 15-month-old boy with renal hypouricemia who presented with acute renal failure, anuria and sepsis due to bilateral obstructing ureteral uric acid stones. He was treated successfully with extracorporeal shock wave lithotripsy. Metabolic survey of 10 relatives revealed a rare hereditary disorder in 4 siblings: isolated renal hypouricemia and hyperuricosuria. To our knowledge this is the youngest reported case of hereditary renal hypouricemia and 1 of the youngest patients to be treated with extracorporeal shock wave lithotripsy.

In the years 1990-1994, 43 patients with ruptured abdominal aortic aneurysms (RAAA) were operated on at the Department of Vascular Surgery of the Na Homolce Hospital in Prague. Men outnumbered women, average patient age was 70 years. The mean delay between onset of symptoms and hospital admission counted 27 hrs. Prior to transportation, one half to two thirds of patients went through at least two types of confirmative evaluation (CAT, ultrasound, angiography) and/or were referred via two or more hospital departments. In two thirds of patients profound shock with oligoanuria and hypotension were found. Anuria/hypotension proved to occur in a significantly lower rate in later survivors compared to later dead (11.8% vs. 23.5%: p < 0.05). Persistent hypotension during surgery together with eventual resuscitation as well as free blood found within the abdominal cavity showed up as further ominous factors. Renal failure was the leading postoperative complication (51.2%) with 27.9% of patients requiring hemodialysis after repair. Sepsis (25.6%), pneumonia (20.9%) and hemorrhage (13.9%) followed. Twenty-six patients were lost (60.5%) either within the first hours and days after surgery because of irreversible hemorrhagic shock or between the second and fourth week due to the sequels of organ failure and sepsis. In our cohort, regardless of age, sex, concomitant disease or the type of surgery, the patient's status on admission determined his/her further destiny. Urgent transfer to a specialized center going hand in hand with prompt and effective reanimation steps are the patient's only hope for survival.

Acute renal failure (ARF) in burn disease results in a range of phenomena important not only from theoretical, but also from practical point of views, whose causes are manifold. ARF is generally defined as a rapid renal failure resulting in accumulation of protein metabolism degradation products (catabolism). It has been known, for some time, that thermal agents do not produce only local skin damages, but also disturb the integrity of the whole organism producing major functional damages of all organs and systems. Most frequently organs affected by burn disease are the following: the lungs, the heart, the kidney, the liver and blood coagulation systems. There are many factors influencing the renal function during the burns. The most important are: decreased cardiac output, respiratory failure with hypoxia and acidosis, toxaemia and sepsis [1, 4, 6 7, 8-10, 12, 19]. ARF in burn disease may be early due to hypovolaemia and hypoperfusion of the kidneys or late, occurring after a week as a consequence of infection and endotoxaemia. Development of ARF in burn disease is a very unfavorable prognostic sign necessitating a complex evaluation. Anuria in an early phase of burn disease may indicate the development of ARF, particularly if urine findings are positive to haemoglobin, proteins, myoglobin, which is of the utmost importance in deep burns inflicted by high voltage current. The immediate cause of anuria in burn disease may be a reflex transfer and penetration of the large quantities of toxic materials into the circulation form the region affected by burns leading to the spasm of afferent glomerular arteriolae producing sudden discontinuation of glomerular filtration. After burns, sudden increase in the osmotic activity ensues in the affected tissue. Some low molecular links may result, and such particles tend to change the osmotic balance and stimulate the development of oedema, and if not excreted, they increase osmolarity. In 20-30% of the patients with burn disease anuria is absent [2, 5, 11, 14, 18, 20]. The genesis of burn disease-associated anaemias is therefore multifactorial. These factors are the following: haemorrhage, haemolysis and etrythropoiesis level decrease. In massive burns, large amounts of non-specific inflammatory components are produced as well: prostaglandins, histamine, quinines leukocyte phenomena, bacterial toxins, etc. [1, 6, 13-16]. The study based on a years-long treatment of our patients with burn disease included on 100 patients. The youngest of the patients was 14 years old, and the oldest 65 years. The percent of burns-affected body surface ranged from 25% to 75%. In 3/4 of the patients the picture of an early renal failure developed, with oliguria immediately after infliction of the burns with rapid increase of serum urea and creatinine levels, while in 1/4 of the patients ARF occurred on the eighth day following the infliction of the burns. "late form of acute renal failure". Among our series with burn disease, anuria was present in 34.0% of patients and oliguria in 25.0%. ARF (early phase) occurred in 59 patients, 38 patients had no sing of ARF, while late ARF developed only in 3 patients. ARF-associated mortality rate was high among these patients (23%), being 6% among anuric patients with ARF and 17% in patients with ARF with anuria. Seventy-seven percent of the patients survived, and their serum and urine analyses performed upon subsequent out-patient follow-up examinations ranged within normal values. Such high percentage of survival among our patients included in the study is based on an early diagnosis of ARF, understanding of pathophysiology of shock associated with burn disease, adequate therapeutic approaches, including both medicamentous treatment and extracorporeal haemodialysis along with early surgical management (Shema 1, 2). For the time being, haemodialysis is the most effective therapeutical procedure in the treatment of ARF, although the mortality rate of dialyzable patients

Adrenalin insufficiency associated with adrenal hemorrhage, is a rare complication after cardiac surgery in neonates. A boy suffering from transposition of the great arteries, who had an arterial switch-operation on day three of his life, acquired a bilateral adrenal hemorrhage. Clinically the situation resembled a septic shock. Despite large doses of catecholamines, he continued to have severe arterial hypotension, anuria, and kyperkalemia. The clinical condition did not change, although sepsis specific therapy was initiated. Consequently adrenal insufficiency, as a possible postoperative complication, was considered and prednisolon, initially in a dose of 15 mg/kg/d, was administered. The clinical condition improved dramatically. The diagnosis could be confirmed by ultrasound examination and determination of cortisol and ACTH plasma levels. Adrenal insufficiency was only transitory, adrenal sonography on day 135 returned to normal. The surgical procedure on heart-lung bypass, the obligatory anticoagulation and the perioperative stress have to be considered as pathogenetic factors.
