Forty-two arterial blood pH and gas determinations were carried out on 11 patients with fulminant hepatic failure. The most common type of acid-base disturbance was that of respiratory alkalosis in 22 cases (52.4%). This was partially compensated in 13 subjects (31.0%) while an accompanying metabolic alkalosis was present in 9 (21.5%). Partially compensated metabolic acidosis was observed on 15 occasions (35.7%), all of which were in patients with laboratory evidence of impaired renal failure. The mental status of the patients was evaluated in each of the categories of acid-base disturbances. Some degree of correlation was evident between the PCO2 and the magnitude of base excess and that of the severity of the encephalopathy. The lower PCO2 and greater negative base excess values tended to be nearly always present in totally comatose subjects. By contrast, there was no clear cut relationship between pH and mental state.

Computerized EEG was performed in 20 patients with renal failure before and after haemodialysis (HD), applying spectral analysis and Hjorth's EEG descriptors in EEG quantification, correlation and factor analysis as statistical procedures to analyse the connections of EEG, blood variables and psychological performance. The main results were: (1) Moderate uraemic encephalopathy -- according to Kiley's (1971) standards -- was present in most of our patients, before and after HD. (2) Before HD, EEG slowing was most strongly connected with the creatinine level and EEG acceleration with hyperkalaemia, which in most cases accompanied a high urea level. (3) Significant EEG changes after HD were: decrease of percentage delta activity, increase of Hjorth's 'mobility', decrease of Hjorth's 'complexity'. (4) The theta/alpha ratio (Matousek 1968) was significantly correlated with the patient's general clinical state after HD. (5) Visual discrimination, memory and maximal tapping speed improved significantly after HD. Only Hjorth's EEG parameters were correlated with test performance in that patients with low voltage and fast EEGs did worse in visual discrimination.

Enteral hyperalimentation in four patients with severe alcoholic hepatitis and anorexia increased spontaneous food intake, increased their nitrogen balance and the patients improved clinically. Seven patients with alcoholic hepatitis, who were clinically ill and able to eat only 410-1,100 calories per day, were given a 900 mosM/l. parenteral "hyperalimentation" solution by a peripheral vein (P-900). The intravenous nutrition provided daily 51.6-77.4 gm. amino acids in addition to oral intake. All patients improved. None developed detectable encephalopathy after 16-42 days of P-900 therapy. Five additional patients had ascites and alcoholic hepatitis. The daily infusion of 2,000 ml. P-900 was not associated with hyponatremia, renal failure or encephalopathy in four of these five patients who improved and continued their diuresis. P-900 therapy was discontinued in one because of progressive hyponatremia. The observations indicate that over and above the maximum tolerable oral nutrition, intravenous nutrition can be effectively utilized by clinically ill, jaundiced patients with alcoholic hepatitis without precipitating encephalopathy or interference with standard therapy of ascites.

Arterial hypertension, either transient or persistent, may be induced or aggravated by ingestion of various chemical agents, such as drugs, poisons, and food. Most of these agents either cause sodium retention and expand extracellular fluid volume or act as direct or indirect sympathomimetics. Others act directly on arteriolar smooth muscle. For a few agents, no precise mechanism has been ascertained. Hypertensive reactions may also occur as a result of drug interactions or food and drug interactions. In addition, paradoxical increases in pressure may be encountered during or after discontinuance of antihypertensive therapy. In general, these pressure increases are small and transient; however, a few have been associated with severe hypertension involving encephalopathy, strokes, and irreversible renal failure. Careful review of a patient's drug regimen, including over-the-counter preparations, may avoid chemically induced hypertension. Identification of any offending or incriminating agent will prevent the labeling of a chronic illness and obviate the need for lifelong antihypertensive therapy.

Serum octopamine levels were significantly higher in twenty patients with fulminant hepatic failure (FHF) during the first 48 h of grade IV coma than in health control subjects (3.38 +/- 0.20 ng/ml and 1.75 +/- 0.19 ng/ml respectively, P less than 0.001). Serial measurements in five patients who died without regaining consciousness showed serum octopamine to remain raised, and concentrations in the cerebrospinal fluid at death reflected serum levels. In five patients who regained consciousness, improvement in encephalopathy was associated with a significant reduction in serum octopamine. Renal failure in patients with FHF was found to contribute to raised serum octopamine but could not alone account for the observed levels. Patients given neomycin therapy did not have significantly lower serum octopamine levels than an untreated group. There was, however, a significant correlation between elevated serum octopamine and the occurrence of gestrointestinal bleeding during the previous 24 h. Charcoal haemoperfusion did not appreciably reduce serum octopamine levels.

Complications are the major causes of illness and death after burning and most of them stem from the burn wound. Their origin and importance are reviewed with emphasis on problems and growing points in knowledge. Fluid leakage from the circulation into the burn is the cause of hypovolemic shock, but the underlying permeability changes in the burn are only partly understood. Other nonbacterial complications include acute cardiac failure, acute anemia, hemolytic jaundice, renal failure, encephalopathy, complex hypermetabolic effects including pseudodiabetes, gastric and duodenal ulceration, deep vein thrombosis and pulmonary embolism, pulmonary and glomerular microthrombosis, hepatic jaundice, and arterial thrombosis. Involvement of the airway in conflagrations carries special hazards like glottic edema and inhalation of irritant fumes. Nowadays, bacterial causes are dominant and these remain the main challenge. Bacterial infection and invasion of the burn are usually responsible for septicemia, bronchopneumonia, and pyelonephritis although other sources also contribute. Indirect manifestations of septicemia include paralytic ileus, acute gastric dilatation, toxic myocarditis, and some cases of renal failure. Therapeutic complications like agranulocytosis, thrombocytopenia, and colitis occur at times. High concentrations of oxygen given therapeutically can produce fatal aseptic hypoxic pneumonitis.

Plasma renin activity has been measured daily in 36 patients suffering from self poisoning with acetaminophen. In 3 developing porto-systemic encephalopathy terminal renal failure developed with high plasma renin activity. In 2 who developed acute renal failure without porto-systemic encephalopathy, plasma renin activity was noted to rise before serum creatinine and to return to initial levels after 3 or 4 days while renal failure persisted. Six other patients with similar hepatic damage showed comparable rises in renin without developing renal failure. Our findings are consistent with but do not establish a pathogenetic role for renin in acetaminophen-induced acute renal failure. It is suggested that other factors may act with renin to bring about renal failure.

Congenital Hepatic fibrosis is an uncommon disease, which is autosomal recessive. Two forms of the disease are distinguished: a rare one becoming manifest in the neonatal period with signs of progressive renal failure secondary to polycystic kidneys, in such cases the liver fibrosis is usually asymptomatic, and the diagnosis is therefore often first established post mortem. In the other more usual form the patients present during infancy with bleeding from rupture of esophageal varices caused by portal hypertension. One case is reported, and the history of his two brothers are referred to. In our case a portacaval anastomosis was performed and the patient is asymptomatic with no signs of encephalopathy. His two brothers died, one of bleeding from esophageal varices, the other of hemolytic anemia. In both cases the diagnosis was first made post mortem.

The progressive encephalopathy observed in 5 children with chronic renal failure was clinically similar to the so-called dialysis encephalopathy of adults, except that it was not related to dialysis therapy. Renal osteodystrophy is more prevalent in children than in adults and often more severe. The attempt to control the crippling deformities of renal osteodystrophy in growing children with renal insufficiency has led to the use of large quantities of aluminum containing antacids. The encephalopathy observed in children with chronic renal failure may be related to the oral ingestion of aluminum containing compounds in the presence of persistent secondary hyperparathyroidism. We suggest that alternative methods for the adequate control of serum phosphorus levels should be sought and indications for parathyroidectomy in children reevaluated. During the past 18 mos we have lowered the dose of aluminum containing compounds to 50 to 100 mg/Kg/day in our patients with progressive renal failure and recommend parathyroidectomy. No new cases of the encephalopathy have occurred.

Hepatic dysfunction occurs in up to 10% of patients with sickle cell crisis; however, hepatic failure is quite unusual. Cocaine hepatotoxicity has recently been recognized in humans with liver biopsies showing varying patterns of necrosis. Most patients reported with cocaine intoxication have rhabdomyolysis with renal failure, and half of the cases have been fatal. A patient with concomitant sickle cell crisis and cocaine intoxication presented with hepatic failure, coagulopathy, and encephalopathy. Transjugular liver biopsy showed focal areas of confluent necrosis and large areas of collapse. Cocaine intoxication should be considered in the differential diagnosis of hepatic failure in patients with sickle cell anemia.
