Fifty-nine patients were seen with oliguria in 1975. Forty had acute renal failure (ARF) and 19 rapidly reversible oliguria (RR). The causes of the oliguria were medical (64%), surgical (27%) and obstetrical (9%). The following were valuable in the assessment of patients with oliguria: urine sodium concentration (UNa) and osmolality, coagulation studies and high dose intravenous urography. Patients presenting with a high UNa or a coagulation abnormality were more likely to have ARF. Central venous pressure monitoring was helpful in the initial management but the administration of diuretics was not. Twenty patients with ARF were treated conservatively and the remainder by dialysis. Infection was both the commonest complication of ARF and the most frequent cause of death. Seventy percent of those with ARF died. Death was more common in the elderly or patients with a medical aetiology. The mortality of ARF remains high in spite of advances in the management of its metabolic and infective complications because of the acceptance of more high risk patients. An improved awareness of the preventable causes of oliguria is apparent.

The records of 110 patients with acute renal failure (ARF) admitted to the Department of Medicine of the Philippine General Hospital during a 5-year period (1983-1988) were reviewed. The objectives were to evaluate the clinical profile of ARF patients and to determine what factors influenced mortality. Infection significantly influenced the causation and prognosis of ARF. Fifteen patients died, for an overall mortality rate of 14%. Forty-six clinical variables were analyzed in order to identify factors correlated with mortality. Four variables significantly increased the risk of death from ARF: older age, hyperkalemia, oliguria, and presence of sepsis on admission. These characteristics define a subset of patients for whom more aggressive treatment of ARF is warranted.

Liver transplant is the first therapeutic choice in most of the advanced liver diseases. Nevertheless, its performance originates a number of complications derived from: a) conservation techniques of the organ (in our study a prolonged time of hot ischemia was significantly associated with); b) surgery (all patients who required massive blood transfusions developed metabolic alkalosis); c) the graft itself (all the F 1. degrees were significantly infected), and d) extrahepatic causes (cyclosporin was responsible for high blood pressure and nephrotoxicity which appeared as oliguria with good response to furosemide, as well as hyperglycemia). Some other relevant results in our series were: right pleural effusion and thrombopenia which appeared with a high incidence. Infections were usually originated the staphylococcus which grows in half of the cultures. We also want to highlight the short mean stay and the low mortality incidence in the ICU.

Sixty-one hospitalized infants aged one day to six months were enrolled in an open, multicenter noncomparative clinical study of the efficacy and safety of imipenem/cilastatin. Patients weighing less than 1500 g (four males/ten females, Group 1) and those greater than or equal to 1500 g (31 males/16 females, Group 2) were analyzed separately. Total daily dose (divided into b.i.d. (27) or t.i.d. (34) regimens) ranged from 50 to 101.4 mg/kg given for 10.8 days (means, range 2 to 35 days) for Group 1 and 39.7 to 103 mg/kg given for 11.2 days (means, range 1 to 41 days) for Group 2. The investigators graded the intensity of signs and symptoms of infections as moderate or severe in 86 and 91% of patients in groups 1 and 2, respectively, and bacterial pathogens were isolated pretreatment in 43 and 32% of patients. Eighty-eight percent of all bacterial pathogens were susceptible to imipenem in vitro. The most commonly isolated pathogens were Pseudomonas aeruginosa and Klebsiella pneumoniae. Patients who had confirmed bacterial infections and who did not receive concomitant antibiotics were considered evaluable for efficacy, including 6 (43%) in Group 1 and 15 (32%) in Group 2. Infection sites were (Group 1) respiratory (100%), and (Group 2) skin and skin structures (33%), urinary (11%), gastrointestinal (11%), septicemia alone (11%) and meningitis or respiratory (28% and 6% with sepsis, respectively). Safety analysis included all patients. Imipenem/cilastatin was well tolerated in 93% of Group 1 and 85% of Group 2 patients. Three patients' treatments were discontinued due to rash, oliguria or poor local tolerability. Three patients in Group 1 and four in Group 2 died; deaths were considered unrelated to imipenem/cilastatin. Results are as follows: (table; see text) In summary, 81% (17 of 21) of evaluable patients were clinically cured or improved, among whom 3 of 21 patients (14%) had serious clinical or laboratory adverse experiences which were considered possibly related to imipenem/cilastatin. These results are comparable to results reported with other single or multiple antibiotic regimens.

We studied 385 episodes of nosocomial bloodstream infections occurring over 45 months to ascertain if the etiologic organisms were independent predictors of death and morbidity. Independent predictors of death included respiratory failure, oliguria, metabolic acidosis, hypotension, increased age, antibiotic therapy in cases where susceptibility data were unknown, and infection with Pseudomonas aeruginosa. If parameters associated with septic shock were excluded, increased age, severity of disease, and infection with Candida spp. or P. aeruginosa predicted death. Infection with P. aeruginosa, Enterococcus, and Klebsiella pneumoniae predicted hypotension; severity of disease, polymicrobial infection, and infection with Candida spp., Enterococcus, Enterobacter, or Serratia marcescens predicted oliguria; infection with Candida spp. or P. aeruginosa, increased age, severity of disease, and inability to meet hospital financial obligations without assistance predicted respiratory failure. Inability to meet hospital financial obligations without assistance and severity of disease predicted hypothermia; infection with Candida spp. or P. aeruginosa and sex (male) predicted metabolic acidosis.

162 children with infantile spasms were treated with ACTH at the Children's Hospital, Helsinki, and at the Aurora Hospital, Helsinki, during 1960--76. In a large proportion (37%) of the children the treatment caused pronounced side effects, and the mortality was 4.9%. The most common complications were infections: septic infections, pneumonias, and urinary and gastrointestinal infections. Other side effects were arterial hypertension (11), osteoporosis (2), hypokalaemic alkalosis (2), and other marked electrolyte disturbances (10). In children necropsy showed fresh intracerebral haemorrhages. Four children developed oliguria and hyperkalaemia during and after withdrawal of ACTH. One of them had tubular necrosis confirmed by renal biopsy. Infections were significantly more common with large doses (120 units) of ACTH than with small ones (40 units). It is concluded that side effects, even severe ones, are more common during treatment than had been assumed. Careful watch is important before and after treatment. The benefit of very high dosages should also be reconsidered.

The aim of our study was to analyze the clinical course and outcome of acute renal failure (ARF) in patients with hemorrhagic fever with renal syndrome (HFRS). From 1983 to 1995, we treated 33 patients (27 males, 6 females) aged from 16 to 71 years. Half of patients were connected with work at a farm or in a forest. The disease was confirmed serologically with indirect immunofluorescence test (IFT) and enzyme-linked immunosorbent assay (ELISA). In 18 patients percutaneous kidney needle biopsies were analyzed. In 85% of the cases, the disease broke out from June to October. The most frequently expressed clinical signs and symptoms were fever, nausea/vomiting, headache, backache, abdominal pain, myalgia, diarrhea, conjunctival injection, and hemorrhages. Four patients had concomitant pancreatitis. In 25 patients, oliguria was present, and transient hemodialysis treatment was needed in 19 patients. Infection with Hantaan virus was established in 20 patients and with Puumala virus in 13 patients. At renal biopsy, acute interstitial nephritis accompanied with hemorrhages and necrosis was found, and at a later biopsy there were also signs of interstitial fibrosis. All patients were cured, but renal function was not completely recovered in some. We conclude that ARF is a serious complication in patients with HFRS. Although not lethal in our group of patients, many of them showed severe signs and symptoms of illness. Transient hemodialysis was necessary in two-thirds of the patients. Some degree of functional defects and morphological changes might persist.

Prophylactic hemodialysis has been employed in the treatment of 15 patients with acute renal failure due to acute tubular necrosis (12), bilateral renal cortical necrosis (two), and poststreptococcal glomerulonephritis (one). Dialyses, usually lasting six hours each, were begun before clinical evidence of uremia developed in each patient and/or before the nonprotein nitrogen reached 200 mg.%, and were repeated daily or often enough to maintain the nonprotein nitrogen below 150 mg.%. The hypothesis underlying this technic postulates (1) that wasting, sepsis and impaired wound healing in these patients may reflect tissue injury by the same dialyzable toxic agents which produce the uremic symptoms that are readily reversible by dialysis, and (2) that repeated dialyses should therefore prevent both clinical uremia and the later, often lethal sequelae. The results contrast dramatically with our own past experience in treating patients with acute renal failure with a carefully executed medical regimen together with hemodialysis on conventional indications. Except in one instance of crush injury with progressive intracerebral damage, and one brief occasion in another individual, these patients experienced a stable, convalescent clinical course, remained free of uremic symptoms or chemical imbalances, ate at least three meals daily which were unrestricted in amount and composition, and were ambulatory between dialyses unless confined to bed by associated disease. Wounds healed well. Infection either did not occur, or subsided after appropriate therapy. Fluid restriction was liberalized by means of ultrafiltration with dialysis. Regional heparinization of only the extracorporeal circuit eliminated actual or impending bleeding as a contraindication to dialysis. Chronic vessel cannulation made the frequent dialyses possible, but may have provided the route for repeated, transient bacterial contamination of the blood stream in the first hour of many dialyses. Marked anemia, despite reticulocytosis, moderate to mild weight loss and some mental deficit persisted in spite of the general clinical improvement and well-being. Three patients with tubular necrosis died after seven, 11 and 26 days of oliguria; both patients with bilateral renal cortical necrosis also succumbed, on the seventy-third and ninety-second days of renal failure, and after 29 and 40 dialyses, respectively. At autopsy, evidence of sepsis was conspicuously absent. The remaining 10 patients survived. Thus some, but not all, clinical manifestations of acute renal failure appear to be favorably influenced by prophylactic dialysis treatment. Our initial experience in this group of 15 patients does not of course prove that freedom from complications and a significantly better outlook for survival can be assured to patients with acute renal failure by these methods. However, it seems to offer a reasonable hope of this possibility which we cannot attach to management by medical measures alone, or by dialysis on conventional indications. If this hope is realized in greatly extended, subsequent series, then it seems inevitable that some form of prophylactic dialysis, or some equally effective alternative, should be adopted in treating the majority of patients with acute renal failure.

Acutely increased intraabdominal pressure can lead to multisystem organ dysfunction. Organ dysfunction consists of acute pulmonary failure secondary to compressive atelectasis and associated with high peak inspiratory pressures and impaired gas exchange, acute renal failure with marked oliguria without hypernaturia, intestinal and hepatic ischemia possibly leading to bacterial translocation or necrosis with peritonitis, increased intracranial pressures which may cause brain dysfunction or aggravate head injury edema, venous thrombosis and thromboembolism, and abdominal wall ischemia or necrosis. The diagnosis is made clinically in a patient with high peak inspiratory pressures, oliguria and an apparently tight abdomen, although urinary bladder pressure > or = 20 cm H2O pressure is suggestive. However, chronically increased intraabdominal pressure as is seen in the morbidly obese, pregnancy and cirrhosis may be misleading. As to treatment, once the diagnosis is made, the patient's abdomen should be opened and the tension relieved. The intestinal contents need to be protected and evaporative water loss minimized by either closing the skin and not the fascia or, if this is not possible, using an impermeable protective dressing. If the abdomen is difficult to close at the primary operation, it is best to prevent the development of an acute abdominal compartment syndrome by closing only the skin or leaving it open and using an impermeable dressing. In conclusion, the acute abdominal compartment syndrome has become increasingly recognized as a cause for multisystem organ failure. Recognition of the problem or prevention is mandatory for optimal patient survival.

The factors associated with a greater mortality risk in infants and young children undergoing dialysis have not been clearly determined. We report the results of a North American Pediatric Renal Transplant Cooperative Study designed to assess risk factors in patients aged younger than 6 years at initiation of dialysis therapy. Sixty-four nonsurvivors were matched with 110 survivors for age at dialysis initiation, primary renal disease, and year of entry onto the database. Questionnaires on 137 patients (51 nonsurvivors, 86 survivors) were completed by participating centers. Seventy-five percent (103 of 137 patients) of the patients were aged younger than 2 years at dialysis initiation; 42% (58 of 137 patients) had renal aplasia, dysplasia, and/or hypoplasia or obstructive uropathy; 62% were boys; and 62% were white. One-year patient survival rates were 83% in infants beginning dialysis at younger than 3 months of age, 89% in 3- to 23-month-olds, and 95% in 2- to 5-year-olds (P = 0.001). Comorbid nonrenal disease occurred in 37 of 51 nonsurvivors (74%) versus 46 of 84 survivors (55%; P = 0.027). Nonsurvivors had pulmonary disease and/or hypoplasia more often (14 of 37 nonsurvivors; 37.8% versus 8 of 46 survivors; 17.4%; P = 0.04). Oliguria or anuria was present in 23 of 33 nonsurvivors (70%) aged younger than 2 years versus 26 of 64 survivors (41%; P = 0.007). Infection accounted for 15 of 51 deaths (29.4%). In summary, these results suggest that age at dialysis initiation; presence of nonrenal disease, particularly pulmonary disease and/or hypoplasia; and oliguria or anuria in children aged younger than 2 years are identifiable as risk factors for mortality in these young patients.
