Rheumatic fever--is a social disease; it's incidence is connected with the sensitivity of the patients and infection--group A streptococcus. Such factors as social and economic conditions, accessibility of public health services and environmental factors may influence the spread of streptococcus. In the last decade the mortality rate (rheumatic cardiac failure) decreased in the Republic of Cuba from 4.2 x 10(5) in 1968 down to 2.1 in 1985. It's incidence was within 2.1 and 6.0/1.000 (children at an age of 5-14 years).

As many as 76 patients suffering from inactive rheumatic fever associated with different stages of heart failure were examined for uricemia, diurnal uricosuria, and xanthine oxidase activity in blood serum. It was established that in rheumatic fever, the activity of xanthine oxidase increased even at the early stages of heart failure. The presence in some of the patient of the enzyme activation combined with hyperuricosuria and normal content of uric acid in blood serum suggests "latent" hyperuricemia. In patients with severe heart decompensation, there was an appreciable activation of xanthine oxidase, which correlated, as a rule, with high hyperuricemia. Activation of xanthine oxidase in patients with rheumatic fever evidences hyperproduction of uric acid. It is advisable that in such cases the uricodepressive treatment may be indicated.

Forty-six children with acute rheumatic fever were admitted to Coronation Hospital, Johannesburg, between April 1981 and December 1984; 4 of them were admitted twice during this period. Their ages ranged from 4.5 years to 12.4 years. Carditis was present in 26 patients, arthritis in 22, chorea in 14, subcutaneous nodules in 3 and erythema marginatum in 2. Three patients died and a further 3 had to undergo emergency valve replacement for intractable cardiac failure. Thirty-five developed rheumatic heart disease; they all had mitral regurgitation. Compliance with prophylaxis was acceptable in only 22 cases.

Rheumatic fever has been disappearing in the United States, especially during the past two decades. In the past two years, however, there have been 40 patients seen at the Columbus (Ohio) Children's Hospital diagnosed as having acute rheumatic fever. In marked contrast to the infrequency during the preceding ten years. Twenty of the 40 patients had carditis. Five of these patients were suffering from heart failure, and there was one death. The cause for this outbreak has not yet been found, but some possible causes are discussed. A possible nationwide resurgence of this disease may be heralded by our experience and that of others.

A total of 75 patients with rheumatic fever, 49 acute (ARF) and 26 acute-on-chronic (A-C-RF), registered in the Zimbabwean Midlands during a 7 year period [1973-1980], followed up for 1-12 years where each one had a potential of follow-up of at least 5 years, were reviewed. Their mean age at diagnosis was 13.2 +/- 7.9 (range 3-39) years and 5 of them were over thirty years old. Thirty five percent were followed up regularly although only 20% realised the full potential. 12% of ARF who initially had no carditis, developed it on a recurrence. The disease was more florid among defaulters than among regulars; chronic valvular lesions being clinically established in 2.8 +/- 1.8 (range 1-6) years; chronic heart failure developing in 5.2 years and death occurring in relatively young patients aged 10.9 +/- 3.0 years old. There were more recurrences among defaulters than among regulars (p less than 0.001). The follow-up was better in those with clinically established valvular lesions, worse in the asymptomatic ones and it was unrelated to age or residence. In addition to improving social-economic conditions, parenteral penicillin prophylaxis should be continued until one is at least 40 years old.

The features of rheumatic heart disease in 31 Nigerian children aged 5-11 years are presented. The majority of these children sought medical attention when they were in advanced cardiac failure. In approximately 23% of the children a past history of acute rheumatic fever was obtained. It is suggested that in developing countries, skin ulcers may be as important a focus of beta-haemolytic streptococcal infection as the throat is in developed countries in the aetiology of acute rheumatic fever. Rheumatic heart disease in developing countries present two main problems, namely, diagnosis and management including prophylaxis. The differential diagnosis of rheumatic heart disease in some tropical countries and the factors which affect the management of the disease are discussed.

The initial attack of acute rheumatic fever is hardly ever diagnosed in our environment. Most cases of acute rheumatic fever are seen during recurrent illness when cardiac damage is already severe and death from cardiac failure common. In the absence of effective primary prophylaxis against rheumatic fever in the foreseeable future it is important to find every case of acute rheumatic fever at the first attack, as on this would depend effective secondary prophylaxis and, hopefully, reduction of the morbidity and mortality rates. A prospective study was set up to achieve this aim. All cases suspected of having rheumatic fever among children seen at the Lagos University Teaching Hospital over a period of five years were subjected to the Jones' diagnostic criteria for diagnosis, and grouped into "Initial illness" and "Recurrent illness" groups. Twenty-one cases of acute rheumatic fever were diagnosed during the period, out of which ten (47.6%) were in the initial stage of the illness. There was a direct relationship between the severity of cardiac involvement and delay in recognition of the condition. It was concluded that efforts aimed at prompt recognition of the initial illness would be rewarding in minimising cardiac morbidity and mortality.

Due to the lack of specificity of the clinical picture in the right-sided infective endocarditis, the correct diagnosis is rarely made. We reviewed 30 cases with right-sided or right and left infective endocarditis, treated in the INC from 1946 to 1982. The average age was 20 years. Rheumatic fever (53%), congenital heart disease (40%) and cardiac prostheses (7%) were the more common underlying diseases. The diagnosis was made on an average 7.3 months after the first symptom. Heart failure (93%), fever (76%), weight loss (73%), haemoptysis (66%) and general malaise (53%) were the predominant symptoms. There was no diagnostic suspicion in 9 patients (30%) and in 7 from 16 with negative blood culture, the infection was exclusively right-sided. Peripheral and pulmonary embolism was the most frequent complication. (66%) There were 29 deaths (96.6%). In all of them the diagnosis was confirmed in the postmortem examination. Heart failure and septic shock were the main causes of death. Almost all patients were infected with gram-negative germs and staphylococcus Aureus. This diagnosis should be suspected in a patient with known heart disease, who develops unexplained heart failure, moreover if pulmonary emboli are a feature. The diversity of the isolated germs is different from other publication that have shown staphylococcus as the most prevalent microorganism. This difference can be explained by the lack of drug abuse in our cases. The mortality rate is higher than in the left sided endocarditis.

Thirty-three children with acute rheumatic fever were studied using echocardiography to characterize heart involvement in this disease. Among 26 subjects with a first episode of acute rheumatic fever, 18 had a clinical diagnosis of carditis and six had heart failure. Heart failure usually resulted from valvular incompetence rather than from myocardial failure in these patients. Conversely, among seven subjects with recurrent rheumatic fever, five had a clinical diagnosis of carditis and four had heart failure. Severe left ventricular dysfunction noted on echocardiography probably contributed significantly to the appearance of heart failure in two of these four subjects. Ten patients were initially believed not to have carditis: a diagnosis of mitral valvulitis was made in two of these ten on the basis of the results of the echocardiographic examination. Echocardiography, which provides important information on the cardiac status of patients with acute rheumatic fever, may help in assessing the prognosis and may be useful in the therapy of these patients.

During the 10-year period 1970-79, 88 patients underwent valve replacement for complications of bacterial endocarditis. The mean age of the patients was 42 (15-60) years. There were 64 men and 22 women. Thirty-three patients had a history of rheumatic fever. In 11 cases the murmur was heard already in childhood. In 44 cases (50%) no heart disease was diagnosed before the onset of symptoms of bacterial endocarditis. Strepto- and staphylococci were the most common organisms found in culture. In 12 cases a dental and in 12 a respiratory tract infection preceded the endocarditis. In 51 cases, however, the origin of the infection remained unestablished. Intractable heart failure and embolizations were most common indications for operation. Only 9 patients underwent operation in the acute phase. Aortic valve replacement (AVR) was performed in 58 cases, mitral valve replacement (MVR) in 19, both AVR and MVR in 6, AVR and aneurysm of sinus Valsalva repair in 3 cases, AVR and repair of VSD in one and AVR combined with myocardial revascularization and replacement of the ascending aorta for aneurysm in one case. The early mortality was 9 patients (10%) and late mortality 9 patients. During follow-up times of up to 10 years, 7 patients experienced embolic complications. They recovered uneventfully. One valve prosthesis was replaced because of thrombosis and another due to paraprosthetic leak. Two patients had a late recurrent bacterial endocarditis 5 and 8 years postoperatively. They were treated conservatively and recovered. It was concluded that after valve replacement for bacterial endocarditis, the risk of recurrent infection is relatively low and that results approaching those for elective valve replacement can be achieved.
