Following a brief outline of the history of haemodialytic technique, the most relevant recent progress is illustrated. Advances include the success of the internal artero-venous fistula for access to the vessels, of "less than" single "greater than" haemodialytic units, of three-times-a-week dialysis, and the creation of new disposable dialyzers of high efficiency and low priming volume. Some of the problems posed by the patient in periodic haemodialysis are then examined (the problem involved in the risk of hepatitis, that of persistent severe anemia even after haemodialysis has been begun and that of osteopathy) and the most suitable measures for preventing or limiting these situations are presented. Finally, survival indices of patients undergoing periodic haemodialysis are examined and it is concluded that, although various clinical problems have as yet failed to find a complete solution, the patient under haemodialysis can enjoy a satisfactory state of rehabilitation to family and working life and survive even for more than ten years after the terminal phase of uraemia.

Recent epidemiological surveys have demonstrated the association between malnutrition and infectious diseases. Parasitic infections, diarrhea, pneumonia, hepatitis and tuberculosis are more frequent and most serious in undernourished people and in infants with low birth weight. Data suggest an increased susceptibility to infectious diseases in individuals with protein-energy malnutrition and with iron-deficiency anemia; circulating lymphocytes and intraepithelial lymphocytes are also reduced in cases of malnutrition. Due to impaired immunological response, the effectiveness of prophilactic vaccination is doubtful in undernourished people; there have been, for example, reports of geographical variations in the response of children to polio virus vaccine. A whole series of strategies must be taken into consideration to break the vicious circle of malnutrition-infection; some of these are: breastfeeding; an improved schedule of vaccinations; nutritional supplement, especially for hospitalized patients; and prevention of low birth weight.

Exposure to infectious bursal disease virus (IBDV) at 1 day old followed by inclusion body hepatitis virus (IBHV) inoculation at 36 days produced typical lesions of hemorrhagic-aplastic anemia syndrome (HAS). The lesions included severe anemia, widespread hemorrhages, and dermatitis. HAS could not be induced in the first 4 weeks of life in chickens inoculated at one day old with IBHV alone or in combination with IBDV. It was concluded that the immunosuppressive effects of IBDV failed to alter the pathogenicity of IBHV in chicks less than 4 weeks old. This resistance was considered to be age-related. Subcutaneous inoculation of day-old chicks with IBDV produced a more severe infection than did oral exposure. Serial passage of IBHV in day-old chicks had no significant effect on the viral pathogenicity.

The serologic response of chickens to infectious bursal disease virus (IBDV) and inclusion body hepatitis virus (IBHV) was analyzed. Inoculation at one day old with either IBDV or IBHV significantly (P less than 0.05) reduced levels of serum gamma-globulins at 4 weeks postinoculation. This response was not elicited by inoculation of IBDV together with IBHV. Birds with experimentally induced or naturally occurring hemorrhagic anemia syndrome (HAS) had serum proteins quantitatively and qualitatively changed from those of controls. Serum protein profiles did not coincide, however, in experimentally infected and naturally infected chickens. Among naturally infected chickens, those that were IBHV-positive upon culture had significantly (P less than 0.05) lower hematocrit values.

The records of 104 patients with culture-proven enteric fever were reviewed and evaluated as to the clinical signs, laboratory findings, pathologic features and complications of the disease. One patient with fatal disseminated intravascular coagulation and enteric fever is also presented. Fever and bradycardia were the leading clinical signs followed by splenomegaly, hepatomegaly and rose spots. The principal complications of enteric fever included anemia, typhoid hepatitis, relapse and bleeding. Evidence of typhoid hepatitis was present in 30% of the patients tested. The pathology consisted of typhoid nodules of variable frequency and size depending upon the severity of the condition. The relationship of typhoid hepatitis to relapse seems to be more than coincidental as four out of seven patients who had relapse had abnormal liver tests. The occurrence of disseminated intravascular coagulation in enteric fever is rare; however, awareness of such a potential complication may be life-saving to the patient.

A 16-year-old girl with myocarditis and hepatitis in the course of mycoplasma pneumoniae infection was reported. She had fever and coughed for ten days prior to admission. At the time of admission infiltrations of the left lower lung field were revealed on the chest X-ray films. The ESR was elevated and CRP+6. There were no leukocytosis and anemia, but S-GOT, S-GPT and LDH were moderately increased. On the 11th day of admission VPC in bigeminy appeared and the third sound was heard. Subsequently biphastic and inverted T waves in leads V2 and V3 and flattening of T waves in leads II and aVF appeared. At the same time, the cardiac shadow was enlarged. Antibody titer to mycoplasma pneumoniae increased to more than 1:640 two weeks after admission and then it decreased gradually. The cold agglutinin test was 1:64 on the 8th day of the disease and then it became normal. ASO, antibodies to DNA and immunoglobulins were normal; ANA, Coombs test and LE test were negative. The abnormal ECG-findings were normalized three months later.

The number of patients who can be kept alive with the aid of chronic intermittent dialysis increases each year all over Europe. Since the percentage of patients who have dialysis at home is increasing, the general practitioner also contact with the medical complications of these patients. The most common of these problems: hepatitis, anemia, neurological disturbances, secondary hyperparathyroidism and cardiac and vascular changes with the usual therapeutic measures are discussed.

The ammonia hypothesis is the most likely explanation for the pathogenesis of hepatic encephalopathy in cirrhosis patients. Reduction of hyperammonemia is therefore the most consistent therapy. From this point of view, the antibiotics have a central significance for the reduction of ammonia formation in the intestinal tract. Equally important is the correction of the hypopotassemia, which may lead to a renally induced hyperammonemia. At the same time, disorders which favor the cerebral toxicity of ammonia, especially anemia and hypoxias, must be compensated. These various measures have improved the prognosis for hepatic encephalopathy of the cirrhosis patient, but were without effect on the course of the coma in severe toxic hepatitis. During the last toxic hepatitis. During the last 10 years, many treatment methods have been reported whose efficacy, however, could not be proved.

The association between anemia and chronic renal failure has been recognized since the early 19th century. With the introduction of regular dialysis treatment, an understanding of all aspects of this uremic complication has become of great importance, including an appreciation of the hazards of multiple blood transfusions. This analysis of hemoglobin levels and transfusion requirements in 84 dialysis patients focuses specific attention on hemolytic mechanisms, blood loss, and the effect of bilateral nephrectomy on erythropoiesis. Because no replacement for renal erythropoietin is available, particular attention must be paid to less important, but partially correctable factors that contribute to anemia. Blood transfusion requirements can then be reduced to a minimum, together with the risks of hypersplenism, hepatitis, and sensitization of the patient to alloantigens.

Acute normavolemic hemodilution is a mean of autotransfusion and allow hepatitis prophylaxis in major surgical procedures which general require homologous blood transfusions. The dilutional drop in blood viscosity is followed by an increased cardiac output, while blood pressure and heart rate remain stable. The CO incerase compensates for the reduced oxygen capacity of the diluted blood. Hemodilution was applied in a total of 88 patients. In 46 cases thorough circulatory and laboratory investigations were performed. While an average of 1785 ml blood was withdrawn and replaced synchronically by plasma substitutes, hematocrit was lowered to 24.8% mean and CO rose from 4.4 to 6.01 l/min. In one half of the patients side reactions were observed that occurred in combination as a syndrome in 8 patients: rise in systemic blood pressure and pulmonary artery pressure, disproportional CO increase, peripheral vasoconstriction, and ST-depression in ECG. The possible pathomechanisms of these side reactions are discussed. A sympathetic adrenergic reaction could be excluded by catecholamine estimation. Hyposia may be assumed to be the more probable reason. Since severe side reactions only occured at hematocrit levels below 26%, the dilution waslimited lately to hct 27%. Patients with coronary heart disease, age greater than 70 years, and anemia less than 12 g% hgb were excepted. In 70% of major surgical procedures, e.g. colonic surgery, homologous blood becomes necessary, in 50% in the amount of 2-4 units. The corresponding blood loss of 1000-2000 ml may be compensated by acute normovolemic hemodilution and autotransfusion. In fact, only 15% of our patients required homologous blood transfusions.
