The clinical, laboratory, and histopathological features of seven cases of Aspergillus fumigatus prosthetic valve endocarditis are presented. The exact nature of the lesion, a combination of infective fungal endocarditis and thrombosis on the prosthetic valve, is discussed and the difficulties in clinical diagnosis are emphasized. Helpful indications were sudden unexplained heart failure with the appearance of new murmurs, and emboli to large or medium-sized systemic arteries. Fever and anaemia were inconstant, and in no case was blood culture or precipitin investigation helpful. Spore contamination of operating theatre air was the likely source of infection, and measures taken to overcome this and other predisposing factors are discussed. Since medical diagnosis is usually late and the few reported cures in this condition have included replacement of the prosthesis, early surgical intervention combined with antifungal chemotherapy is advised.

In this review the pathophysiological mechanisms of general clinical symptoms during the treatment of severe burn injuries (hypovolemia, katabolism, anemia, coagulation disorders, hyperbilirubinemia, hypoxia, cardiac insufficiency and bone disorders) are analysed with special reference to specific therapeutical measures.

In 214 patients with healed myocardial infarction an assessment was made of the prognostic value of risk factors relating to early postoperative cardiac decompensation which occurred in 50 cases. A significant influence was shown by age (greater than or equal to 75 years), pre-existing heart failure and load insufficiency, hypertension (greater than or equal to 180/95 mm Hg), advanced arteriosclerosis with cerebrovascular and renovascular symptoms, infections with fever or septicemia, emergency operations, lang-lasting surgery, decrease in blood pressure during operations (greater than or equal to 70 mm Hg systolic) and postoperative anemia (less than or equal to 3.5 millions erythrocytes/cmm). The postoperative cardiac failure took a lethal course in 60%. Pathogenetically, the discrepancy between O2-requirement and O2-supply in the previously damaged myocardium is of essential importance during the postoperative stress period.

A 91-year-old man had been treated for iron-deficiency anemia for four years before admission to the Geriatric Unit of the Hasharon Hospital because of cardiac insufficiency and epigastric pain. In the Unit, laboratory studies revealed, in addition to hypochromic anemia, a high level of plasma iron and a reduced iron-binding capacity. The low reticulocyte count in the peripheral blood despite hyperplasia in the bone-marrow erythrocyte series, the rapid disappearance of radioactive iron from the plasma, and the impaired erythrocytic uptake of iron were all indicative of the ineffective erythropoiesis. The findings suggested the possibility of sideroblastic anemia, and examination of bone-marrow aspirates stained for iron confirmed this diagnosis.

Following an episode of rheumatic carditis, severe mitral incompetence developed in a 9-year-old girl. A mitral annuloplasty succeeded for a short time in ameliorating her symptoms of cardiac failure. However, mitral incompetence recurred and was accompanied by severe anemia and hemosiderinuria. Distortion of erythrocytes was evident on a peripheral blood smear. A second mitral annuloplasty resulted in resolution of the hemolytic anemia.

Measles-associated pneumonia, which was severe enough to require mechanical ventilation, caused a mortality of 64%. The main indications for special respiratory care were severe infection and hypoxaemia. Complications of the disease occurred in 78% of the patients. The commonest were anaemia, enteritis and cardiac failure, and they contributed to the grave prognosis. Viral pneumonia was present in most of the patients who died; superinfection was rare. The characteristics of measles virus was present in 30% and of adenovirus in no less that 40%.

We measured aortic and central venous pressures beginning soon after birth in 40 prematurely born infants with moderate or severe erythroblastosis fetalis, including 13 with severe and 10 with mild hydrops fetalis. All but four were asphyxiated at birth and this affected intravascular pressures. Before resuscitation, aortic or central venous pressure or both were elevated in more than one third. All but two of the remaining infants had normal initial pressures. Following resuscitation which relieved acidosis, hypoxia, and anemia, but did not reduce blood acidosis, hypoxia, and anemia, but did not reduce blood volume, the high pressures usually fell to normal and occasionally to subnormal levels, normal pressures fell to subnormal in almost one half, and those with initial subnormal pressures remained hypotensive. In all, 40% were hypotensive after resuscitation; treatment with blood volume expanders consistently returned these pressures to normal. Only two of the 13 severely hydropic infants and none of the mildly hydropic had findings indicative of hypervolemia and myocardial failure which persisted after treatment of asphyxia.

Proceeding from their personal 5-years experience comprising over 1500 operations with extracorporeal circulation the authors formulate their tactics of the early postoperative therapy. The attention is mainly paid to the maintenance of the optimum pulmonary gas exchange, adequate haemodynamics and stable homeostasis. An important role belongs to prolonged artificial pulmonary ventilation that was used for therapeutic purposed in 324 cases of cardiac and respiratory insufficiency and for preventive purposes--in 908 patients. The therapeutic tactics for various forms of respiratory and cardiac insufficiency and multiform cardiac rhythm disorders is presented in detail. On the example of 149 patients shows that a moderately incomplete blood replacement in the postoperative period does not result in clearsut anaemia. The authors recommend donor blood transfusions when the hemoglobin level is below 10 Gm%.

A group of 278 patients, over the age of 60 years, and representative of geriatric and general medical admissions to the District General Hospital in Banbury, Oxforshire, was studied to correlate the prevalence of systolic murmurs to age, sex, cardiac failure, ischaemic heart disease, dysrrhythmias, hypertension, peripherial vascular disease and anaemia. The object was to establish the clinical significance of these murmurs and test a postulate that they could not be dismissed as benign. Seventy-five per cent of the murmurs were judged to be aortic and 12 per cent mitral in origin. The prevalence of systolic murmurs increased with age from 32 per cent at 60-64 years to 57 per cent over 85 years, and was greater in females (44 per cent) than in males (34 per cent). The presence of systolic murmurs was related to the presence of cardiac failure, ischaemic heart disease, dysrrhythmias, hypertension, peripheral vascular disease and anemia. Only 8 per cent of patients with systolic murmurs had none of the above-mentioned six cardiovascular abnormalities compared with 36 per cent of patients without such a murmur, while multiple cardiovascular abnormalities were also commoner in the former group. The mortality rate in hospital was similar for patients with or without a systolic murmur.

Nine patients with high-output cardiac failure from arteriovenous forearm dialysis fistulas are reviewed, and six new cases are presented. Decreases in cardiac output with temporary fistula occlusion ranged from 0.3 to 11.0 liters/min (mean, 2.9 liters/min); fistula flow rates varied from 0.6 to 2.9 liter/min (mean, 1.5 liters/min). Surgical correction of high-flow fistulas resulted in notable improvement of cardiac failure in 13 of 14 patients. Although cardiac failure in individuals who are receiving long-term dialysis treatment is usually caused by intrinsic cardiac disease, volume overload, or anemia, forearm fistulas with large flow rates may be an important contributing factor. Correction of these large flow rates may be an important contributing factor. Correction of these large flow rates by banding or closure can substantially improve cardiac function in selected patients.
