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.

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.

Abdominal sepsis and septic shock are still major causes of mortality in intensive care units (ICU). Acute renal failure (ARF) is one of the hallmarks encountered in septic shock. The pathophysiological alterations leading to ARF are poorly understood. A novel murine model of polymicrobial sepsis (colon ascendens stent peritonitis [CASP]) was used to investigate functional renal parameters, renal chemokine transcription levels, and recruitment of inflammatory leukocytes in septic ARF. CASP was induced by inserting a 14-gauge stent into the colon ascendens of C57BL/6 mice, generating a septic focus resulting in polymicrobial sepsis. Mice were monitored for urine output and serum azotemia. Kidneys were harvested for analysis of leukocyte infiltration by immunohistochemistry and chemokine gene expression by RNase protection assay (3, 6, 12, and 18 h). CASP, but not sham-CASP, resulted in anuria immediately after surgery and in elevated serum creatinine and BUN detected 18 h after CASP surgery, confirming acute renal failure. Progressive induction of chemokine gene expression was observed for IP-10, MIP-2, MIP-1alpha, MIP-1beta, MCP-1, and RANTES peaking at 12 h with subsequent decrease. Immunohistochemistry revealed an accumulation of neutrophils and monocytes which had adhered to the renal vascular endothelium. Thus, acute renal failure in sepsis is accompanied by a marked upregulation of chemokines of the CC and CXC group within the kidney.

Acute renal failure (ARF) associated with liver disease is a commonly encountered clinical problem of varied etiology and high mortality. We have prospectively analyzed patients with liver disease and ARF to determine the etiology, clinical spectrum, prognosis and factors affecting the outcome. Other than hepatorenal syndrome patients, out of 221 cases, 66 developed ARF secondary to various liver disease like cirrhosis (n = 29, mortality 8, risk factors-older age p < 0.01, grade III/IV encephalopathy p < 0.05), fulminant hepatic failure (n = 25, mortality 15, risk factor-prolonged prothrombin time p < 0.01), and obstructive jaundice (n = 12, mortality 7, risk factor-sepsis p < 0.01). In these three groups the factors leading to ARF were volume depletion (24), gastrointestinal bleed (28), sepsis (34), drugs (27) [aminoglycosides (9) and NSAID (18)] along with hyperbilirubinemia. Various types of ARF with contemporaneous liver injury were malaria (n = 37, mortality 15, risk factors-higher bilirubin p < 0.001, higher creatinine p < 0.05, anuria p < 0.05 and dialysis dependency p < 0.05), sepsis (n = 36, mortality 22, risk factors-age p < 0.001, higher bilirubin p < 0.01, oliguria p < 0.05), hypovolemia with ischemic hepatic injury (n = 14, mortality 5, risk factors-higher creatinine p < 0.05 and SGPT p < 0.01), acute pancreatitis (n = 12, mortality 4, risk factors-higher bilirubin p < 0.001, higher SGPT p < 0.01, dialysis dependency p < 0.05), rifampicin toxicity (n = 10, no mortality), paroxysmal nocturnal hemoglobinuria (n = 3, no mortality), CuSO4 poisoning (n = 3 mortality 2), post abortal (n = 11, mortality 6, risk factors higher creatinine p < 0.05 and SGPT p < 0.01), ARF following delivery including HELLP syndrome (n = 12, mortality 4, risk factors-higher bilirubin p < 0.01 and SGPT p < 0.01), and of uncertain etiology (n= 14 mortality 4). 133 patients (60.2%), required hemodialysis hemodialfiltration or peritoneal dialysis. ARF associated with liver disease is having high mortality (42.5%). Avoidance of dehydration, hypotension, nephrotoxic drugs and sepsis, with promote dialytic support are necessary to reduce mortality and morbidity.

To evaluate the clinical benefit of the prophylactic use of urate oxidase in children with non-Hodgkin's lymphoma (NHL), we analyzed the incidence and complications of tumor lysis syndrome (TLS) in children with B-cell acute lymphoblastic leukemia (B-ALL) or stage III/IV Burkitt's lymphoma and a lactate dehydrogenase (LDH) level > or =500 U/l before and after the introduction of a protocol amendment to use urate oxidase for the prophylaxis of TLS. Data from 1791 children with NHL enrolled in the two subsequent multicenter studies NHL-BFM 90 and 95 were evaluated. The presence of the side effects TLS, anuria, sepsis, and other complications during the first 2 weeks after admission were registered. Until March 1996, no urate oxidase was used (period 1). From November 1997 all children with B-ALL or stage III and IV B-NHL and LDH > or =500 U/l should receive urate oxidase prophylactically (period 3). In between (period 2), urate oxidase was given in a minority of hospitals therapeutically. Initial chemotherapy was identical. Altogether, 78 children (4.4%) developed a TLS. Patients with B-ALL had the highest risk to develop a TLS (26.4%) followed by B-ALL/Burkitt's lymphoma and a LDH > or =500 U/l (14.9%). In period 1, 16.1% and 9.2% of the latter children developed a TLS or anuria, respectively, compared to 12.3% and 6.2% in period 3 ( p=NS). The incidence of sepsis remained unchanged (5.0% vs 4.6%). In children with B-ALL the differences in the incidence of TLS and anuria between period 3 and period 1 were more pronounced, reaching significance for anuria (15.4% vs 3.8%, p=0.03). Our results suggest that patients with the highest risk to develop a TLS might benefit from the prophylactic use of urate oxidase.

Acute renal failure may be caused by a failure of renal perfusion (pre-renal failure), damage to the renal parenchyma (intrinsic renal failure) or obstruction of the urinary tract (post-renal failure). Most cases of intrinsic renal failure in the newborn are due to asphyxia, often in combination with sepsis and nephrotoxic drugs. Persistent elevation of the plasma creatinine concentration above 132.5 micromol/l (1.5mg/dl) is widely accepted as a diagnostic criterion. Oliguria or anuria may occur but is not always present. Post-renal failure is diagnosed by renal ultrasonography and is treated by relief of the obstruction. Pre-renal and post-renal failure can be distinguished by an analysis of urinary indices, especially the fractional sodium excretion, and by the response to fluid replacement. The conservative management of intrinsic renal failure includes careful attention to fluid balance, maintenance of adequate nutrition and prevention or correction of hyperkalemia, acidosis and hyperphosphatemia. Severe cases may require dialysis: peritoneal dialysis is used in most cases, but extracorporeal methods, including intermittent hemodialysis, hemofiltration and hemodiafiltration, are possible. Congenital chronic renal failure, usually caused by renal dysplasia with or without obstruction, presents in a manner similar to that of acute renal failure, with a progressive deterioration of plasma biochemical values. Dialysis is rarely necessary in the newborn period. The conservative management of chronic renal failure is similar to that of acute renal failure, with particular emphasis on nutrition, control of acidosis and the prevention of renal osteodystrophy by the use of dietary phosphate binders and vitamin D analogs.

Recent studies have indicated that protective lung strategies may improve outcomes in acute lung injury. We hypothesized that the use of a lower tidal volume early during septic shock may protect against the subsequent development of acute lung injury. Fourteen fasted, anesthetized, invasively monitored, mechanically ventilated, female sheep (26.4 +/- 4.5 kg) underwent cecal ligation and perforation to induce sepsis. Sheep were then randomized to ventilation with low (6 mL/kg) or high (12 mL/kg) tidal volumes. A positive end-expiratory pressure of 10 cm H(2)O was applied in each case. Ringer's lactate was titrated to maintain pulmonary artery occlusion pressure at baseline levels. No vasoactive agents or antibiotics were used. Survival time was longer in the low- than in the high-tidal-volume group (21.8 +/- 2.4 vs. 17.6 +/- 4.1 h, respectively, P < 0.05). The times to develop hypotension and anuria were longer in the low-tidal-volume group (18.1 +/- 3.1 vs. 12.0 +/- 2.8 h, P < 0.05, and 17.6 +/- 1.6 vs. 14.1 +/- 3.8 h, P < 0.05). Although the Pao2/Fio2 tended to be lower in the low- than in the high-tidal-volume group (P = 0.06), postmortem examination showed a lower lung tissue wet/dry ratio in the low- than in the high-tidal-volume group (7.1 +/- 0.5 vs. 9.1 +/- 0.7, P < 0.05). A low-tidal-volume ventilation strategy applied early during septic shock may be beneficial in terms of reducing the amount of lung edema and prolonging survival time.
