The clinical and pathological findings in two brothers with biochemically diagnosed Refsum's disease are given. The pathology, in general, was that already described in this condition. An unusual complication in one case was the development of renal failure. Death was caused in the other by heart failure.

Carnitine concentration was measured in plasma, muscle, and dialysate before and after haemodialysis in patients with renal failure and in plasma and muscle of healthy controls. In eight of the nine patients carnitine concentration in muscle after haemodialysis was only 10% of the concentration in controls. Plasma-carnitine varied in patients before dialysis and in all of them was reduced by dialysis. The loss of carnitine into the dialysate (190--2100 mumol/treatment) greatly exceeded the normal loss in urine for most of patients, and was only partly compensated for. In some patients normal or high plasma-carnitine and low concentrations in muscle indicated that the carnitine-concentrating mechanisms in the muscle cell had failed. The reduction in carnitine will interfere seriously with normal cellular functions and this may help to explain the clinical syndrome of cardiomyopathy and cardiac failure which has been observed in some patients treated for a long time with intermittent haemodialysis.

Myocardial involvement in lupus erythematosis takes the form of an interstitial myocarditis with cellular infiltration and fibrinoid necrosis. The most lesions are perivascular, and involve the arterioles. The myocardial fibres are involved secondarily to the vascular lesions, or by grossly, damaging sclerosis. The clinical features are variable:--no clinical features, but haemodynamic evidence of abnormal ventricular function, and perhaps sudden death;--arrhythmias and disorders of atrio-ventricular conduction;--cardiac failure, which may be due to a genuine cardiomyopathy (a part may be played by hypertension, pulmonary hypertension, renal failure, constrictive pericarditis or haemodynamically major valve disorders);--abnormalities of the coronary trunk in a certain number of cases. If anti-nuclear antibodies are present in a cardiomyopathy, the presence of DLE or of a drug-induced lupus syndrome must be suspected. There remain some awkward cases which defy classification, and which systematic use of echocardiography and pericardial and myocardial biopsy may be able to define more accurately.

A fistula located between the abdominal aorta and the inferior vena cava is an unusual acquired condition which necessitates prompt diagnosis and, in most instances, emergency surgical repair. The signs and symptoms are related to the size of the shunt. The classical findings are those of a continuous abdominal bruit, edema and venous pooling of the legs, wide pulse pressure, and sudden progressive high-output cardiac failure. Aortography is the definitive diagnostic procedure. However it is impractical in those situations presenting an asymptomatic fistula and contraindicated in presence of signs of progressive renal failure, where emergency surgical treatment is required. In these instances aorta-caval fistula can be correctly diagnosed by means of radionuclide aortography. The fistula can usually be repaired from within the aneurysm after endoarterectomy. Then the aortic graft replacement is completed. In rare cases the pathology at operation is such that this type of repair cannot be performed and an unexpected replacement of the inferior vena cava may be required. The purpose of this paper is to present the description of a patient in whom the diagnosis of aorta-caval fistula was confirmed by means of an isotope angiogram, followed by a successful surgical graft replacement of the abdominal aorta and a dacron tubular graft replacement of the inferior vena cava.

Adequate antihypertensive therapy will lower blood pressure to normotensive or near normotensive levels in 80-85% of patients. Long-term treatment results in a marked decrease in strokes and stroke recurrence, heart failure, renal failure, and progression to accelerated hypertension. The effects of long-term therapy on the occurrence of coronary artery disease are unclear.

Sixteen cases of lactic acidosis are reported: 7 phenformin treated diabetes, 5 cardiovascular diseases (2 myocardial infractions, 2 pulmonary embolisms, 1 heart failure). In 2 patients no etiology was found. Concomittant renal failure or liver diseases were found in respectively 9 and 4 cases. Patients presented the usual criteria of lactic acidosis: clinical, polypnea, severe hypotension (9/16), peripheral symptoms of shock (12/16), hypothermia (9/16), abdominal pain (9/16): biologically, acidosis (pH = 6,99 +/- 0,01, HCO3- = 5,9 +/- 1,5 mmol), hyperlactatemia (14,1 +/- 3,6 mmol/l) with hig lactate/pyruvate ratio (105 +/- 73), and anion gap (24,3 +/- 4,2 mmol/l). Sodium bicarbonate infusion was performed in all cases (2,5 to 42 mmol/kg). Few cases required volhemic expansion or furosemid induced diuresis. One patient was treated with extrarenal dialysis. 13 patients were alkalinised with less than 185% of estimated deficit measured from alkalin reserve: 12 died. 3 patients received 185% more than this deficit, associated with furosemid (1,8 to 12,5 mg/kg): only one patient died ten days after by casual disease, with lactatemia of 3,2 mmol/l. In spite of the small number of patients, these findings suggest that an early and massive alkalinisation, with large doses of furosemid, can improve the severe lactic acidosis prognosis.

Exertional rhabdomyolysis is a condition arising in several species of newly captured wild animals after some form of physical exertion and stress. It is characterized by muscle necrosis and myoglobinuria. Death may result from secondary renal failure, acute or chronic heart failure and progressive emaciation.

Near-drowning represents an insult that can affect all organ systems. A common pathway for injury is hypoxemia, acidosis, and hypoperfusion. Pulmonary insufficiency and CNS dysfunction are major causes of morbidity and mortality. Variations in vascular volume, heart failure, renal failure, coagulation disorders, and electrolyte disturbances may also be present. Patients should be observed for multisystem failure and therapy tailored to the particular needs of each victim.

In a patient suffering from obstructive cardiomyopathy (IHSS), the onset of septicaemia due to staphylococus aureus was accompanied: 1. by the appearance of massive mitral incompetence and of cardiac failure; 2. by a marked reduction in the left intra-ventricular pressure gradient; 3. by acute reversible renal failure (interstitial nephritis); 4. by a glomerulonephritis with immune complexes deposits. After the septicaemia had been treated, replacement of the mitral valve by a disc prosthesis of Lillehei was carried out. Twenty months after the operation, the patient was completely asymptomatic, and catheterisation showed that the left intra-venticular pressure gradient had disappeared, as had the haemodynamic signs of cardiac failure.

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.
