The hemolytic-uremic syndrome consists of microangiopathic hemolytic anemia, acute renal failure, and thrombocytopenia following a prodromal illness of gastroenteritis or upper respiratory infection. The syndrome can present in dramatic fashion with severe abdominal pain and signs of peritonitis suggesting an acute surgical crisis. In a series of 25 patients, 40% had abdominal pain, 25% had abdominal tenderness, and 20% had peritoneal signs. Clues to diagnosis in the early stages of the acute illness were mild to moderate hypertension, abnormal peripheral blood smear, anemia despite dehydration, and proteinuria. Significant abdominal pain and x-ray evidence of colitis may occur before development of typical laboratory findings, and these were evident in at least one case. Three patients underwent laparotomy for suspected bowel perforation. Colitis without perforation was found in all cases. In the absence of documented perforation, toxic megacolon, or intussusception, the decision to perform laparotomy in patients with hemolytic-uremic syndrome who have signs of peritonitis must be individualized. Failure to recognize the underlying renal problem can lead to serious errors in fluid and electrolyte management and delay of appropriate therapy.

While no unanimity of opinion exists regarding the risk to physical health from smoking marihuana, we have seen four cases that demonstrate clearly that intravenous usage is hazardous. The severity of the multisystemic involvement is dose-related. On initial examination, signs of most severe overdosage included fulminant gastroenteritis, hypoalbuminemia, toxic hepatitis confirmed by serial biopsy, acute renal failure, electrolyte disturbances, leukocytosis, anemia, and a relative thrombocytopenia. In three patients who shared a common needle, gingivostomatitis also developed.

Fifty-two clinical charts of children who had been discharged from this hospital, after being treated for acute renal failure, were analyzed to determine the incidence, presentation and results of the treatment used. We found that 0.7% of the total number of children admitted developed this complication and that 4/5 of them were under two years old. The initial illnesses were gastroenteritis, bronchial pneumonia, cyanogenic cardiopathies and sepsis. Some of the patients had hypoxic episodes or went into hypovolemic shock or a combination of both. In half of the patients diagnosis was reached from anamnesis, from of oliguria, acidosis and nitrogen retention. In the rest from whom a urine sample was obtained, the diagnosis was confirmed when the FeNa was higher than 2 and because the U/P osmolarity and urea were under 1.3 and 5 respectively. The oliguric type of acute renal failure was seen in 65% of the cases; the non-oliguric type in 35%. In the first group the mortality rate reached 6.5% even though a third of them were placed under dialysis. Yet, in another 7 cases, dialysis could not be used because the child was in shock. Of the 18 cases of non-oliguric acute renal failure, 12 recovered; only 3 required dialysis. We conclude that the high mortality rate in cases of acute renal failure depends on the severity of the underlying illness, the age of the patient and the delay in the diagnosis of the disease. The use of dopamine and furosemide, as well as the application of hemoperfusion instead place of peritoneal dialysis in neonates with sepsis, could improve results.

The diuretic effect of high doses of furosemide alone and furosemide plus mannitol was analysed retrospectively in 30 children with acute renal failure. In 10 children (Group 1) renal failure developed mainly during glomerulonephritis, and in 20 children (Group 2) the cause was gastroenteritis. The diuretic effects of furosemide and furosemide plus mannitol were evaluated measuring the 24-hour urine volume at the time of anuria, oliguria or normal diuresis. The highest mean single intravenous doses of furosemide were 6.5 and 14 mg/kg in Groups 1 and 2, respectively; the highest average daily doses were 10.1 and 25.5 mg/kg, respectively. A broad relationship was observed between single i.v. dose and diuretic response following administration of furosemide (1.2 to 30.8 mg/kg). In both groups of patients a statistically significant negative linear correlation was found between the daily intravenous dose of furosemide and the 24-hour urine volume. Calculations based on the obtained regression equations showed that the expected 24-hour urine volumes corresponding to daily diuresis normal for age could be obtained after administration of daily 2.8 to 1.4 mg/kg furosemide in Group 1 and 9.3 to 2.3 in Group 2. It is therefore suggested that the total daily dose of furosemide should not exceed 100 mg in children with acute renal failure. Administration of furosemide plus mannitol did not result in higher daily diuresis as compared to 24-hour urine volume obtained when furosemide was given alone. Furosemide was well tolerated. Electrolyte disturbances, especially in Group 2, were the most frequent side effects due to high doses of furosemide.

The spectrum and outcome of acute renal failure (ARF) were studied in 205 children aged between 1 month and 12 yr. There were 145 boys and 60 girls; 23 per cent were below 1 yr and 49 per cent between 1 and 4 yr. The main causes of ARF were haemolytic uraemic syndrome (HUS) in 36 per cent, serious infections in 19 per cent, acute gastroenteritis and dysentery in 17 per cent, glomerulonephritis (GN) in 13 per cent and intravascular haemolysis (IVH) in 6 per cent. Most patients with HUS, serious infections and gastroenteritis were below 5 yr, whereas GN and IVH occurred in older children. HUS was mostly associated with dysentery; Shigella and several other pathogens were isolated from stools in 35 per cent. In most patients with HUS disseminated intravascular coagulation and renal cortical necrosis were present, with a high mortality. The outcome was also poor in infants with serious infections. IVH occurred in patients with G-6-PD deficiency. In such patients and in those with post-streptococcal GN the prognosis was good. Crescentic GN had a poor outcome. Our observations highlight the common and serious nature of ARF in India. However, most of the underlying causes are preventable.

Between September and November 1988, six children (aged 4-17 months) from a parish in Upper Bavaria fell ill with a haemolytic-uraemic syndrome. The illness had been preceded by a gastroenteritis with at times haemorrhagic stools. All patients needed peritoneal dialysis for acute renal failure. A 12-month-old girl was left with statomotoric developmental impairment due to cerebral involvement, but the other five children were cured. In the first four children to be admitted stool examinations for the common enteritis-causing microorganisms had been negative. But in the following two, specific gene probes demonstrated enterohaemorrhagic E. coli O157: H- with formation of verotoxin 2 (Shiga-like toxin II). This group of microorganisms must be taken into account in the diagnosis of haemorrhagic enterocolitis, because they can cause severe complications.

Twenty infants and young children admitted with severe metabolic acidosis and a positive history of 'muti' ingestion were investigated. All had accompanying gastroenteritis and significant dehydration. Biochemical data was diagnostic of high anion/gap metabolic acidosis in the majority (70 per cent). Further biochemical data indicated that lactic acidosis and pre-renal azotaemia resulting from severe hypovolaemia were likely causes of the high anion GAP metabolic acidosis. There was no evidence to suggest that the ingested muti per se was associated directly with the acidosis or acute renal failure seen in these children.

Nine fatal cases of systemic mucormycosis observed in association with renal failure are described. Four patients were hospitalized for chronic renal failure as a consequence of chronic glomerulonephritis, myeloma kidney, chronic pyelonephritis, and polycystic kidney disease, respectively; and five patients presented with acute renal failure. The underlying causes in three of these five patients were gentamycin nephrotoxicity, acute gastroenteritis, and allograft rejection, respectively, and in the remaining two, acute renal failure was the result of extensive renal vascular and parenchymal invasion by mucor hyphae. Tissue invasion with mucormycosis was documented during life in two patients and at autopsy in seven patients. The infection was disseminated in five patients, and isolated pulmonary and rhinocerebral involvement occurred in two patients each. Our observations have shown that patients with renal failure are prone to develop mucormycosis, which carries a grave prognosis if therapy is not instituted in time.

This study records our experience with 40 infants who developed acute renal failure in a tropical environment over a period of 2 years. All the patients required intermittent peritoneal dialysis. Septicaemia (88%) and acute gastroenteritis (55%) constituted the leading causes of acute renal failure. Haemolytic uraemic syndrome was present in six (18%) patients. An elevated serum creatinine (85%), metabolic encephalopathy (75%), uncompensated metabolic acidosis (75%) and hyperkalaemia (48%) were the major indications for dialysis, while fluid overload was present in only 18% of the infants. Intermittent peritoneal dialysis was used in all the patients and was found to be effective. Procedural complications were minor and infrequently encountered. The clinical course and laboratory data consistent with haemolytic uraemic syndrome was observed in six patients, and acute tubular necrosis was the predominant renal lesion in the remainder. Mortality was 75%. The aetiology of acute renal failure in infants in the tropics differs significantly from that in the West, and even within a given country marked regional variations exist.

Clinical and epidemiological data on 16 patients with HFRS admitted to the University Hospital of Infectious Diseases in Zagreb during the past 10 years (1977-1986) are reported. In 13 of them, the diagnosis was confirmed serologically by indirect fluorescent method. All but two were men between 20 and 45 years of age (80% of patients). The disease appeared sporadically only. According to the domicile, way of living and working all the patients but three mentioned the contact with rodents in the fields or in other places (mill, storehouse). Three patients live in Zagreb and there was no possibility to get infected out of the town. The disease had moderate course, more rarely severe course when shock and acute renal failure developed. General symptoms with fever and algias dominated (febrile stage). Some of the patients had ophthalmic disturbances. Patients with a pronounced gastroenteritis developed shock the most frequently. In some of the patients back and abdominal pains followed by obstipation appeared. HFRS was incriminated disease because of febrile stage followed by the acute renal failure, oliguria, azotemia, polyuria and low urine osmolity. One female patient with active rheumatoid arthritis died after two-week staying in hospital due to irreversible shock followed by cardiopulmonary and renal failure.
