Between January 1977 and December 1982, 34 patients below the age of 20 years (age range 1.9–20 yr, mean 12.3 years) were
treated for 38 episodes of infective endocarditis (IE). Twenty three patients (68%) had rheumatic heart disease (RHD), while
11 had congenital heart disease (CHD). Echocardiography was diagnostic of IE in 10 of 12 patients (83%) in whom it was performed.
Blood culture was positive in only 15 instances (40%), staphylococcus being the most common organism isolated. Twenty eight
(74%) episodes of IE resulted in a cure by medical treatment. Ten patients (26%) died during the medical treatment 9(90%)
because of relentless congestive heart failure and 1(10%) due to cerebral embolism. Infective endocarditis in children is
an important therapeutic problem. Culture negative endocarditis is frequent in our setting. 相似文献

From 1950 through 1989 at Tokyo University's Department of Pediatrics, 25 children were treated for bacterial endocarditis. Twenty-two of these patients had previously been diagnosed as suffering from congenital heart disease. Twenty one of the 25 patients had positive blood cultures. Streptococcus viridans was the most common organism isolated, although the incidence of Streptococcus viridans infection has decreased in the last 20 years. In present series only a few post-surgical cases with congenital heart disease occurred. There were three deaths which all occurred prior to 1965. 相似文献

A retrospective study was undertaken to study children who presented with infective endocarditis (IE) to a university teaching hospital in Beirut, Lebanon, between January 1977 and May 1995. Of 41 patients with IE (24F, 17M), 28 (68%) were diagnosed between 1977 and 1985. Patients' ages ranged from 3 to 18 y (mean age 11.3+/-2.8 y), and 13 patients were <10 y of age. Clinical presentations included: fever (in 88%), heart failure (in 39%), neurologic findings (in 20%) and embolic phenomena (in 22%). Nineteen patients (46%) had underlying congenital heart disease (CHD) with tetralogy of Fallot and pulmonary stenosis being the most common. Sixteen patients (39%) had underlying rheumatic heart disease (RHD). A total of 5 children (12%) with normal cardiac anatomy had IE. One had underlying acquired viral myocarditis with mitral insufficiency. Echocardiography showed vegetations in 60%. Blood cultures were positive in 31 patients (76%). IE occurred in three patients following cardiac surgery. In one patient it occurred within 2 mo of surgery and in the other two it occurred within 6 mo. Streptococcus viridans and Staphylococcus aureus were the two most commonly isolated bacteria. Overall mortality rate was 29% (not statistically significant between patients presenting between 1977-1985 and 1986-1995; p = 0.17). There was no statistically significant difference in mortality among the groups (five in the group with CHD, six with RHD and one with structurally normal heart). This study demonstrates that RHD is an important underlying cause of IE in children in our community. This finding is similar to those in other developing countries and different from those in developed countries. Distribution of pathogens and CHD in our study is comparable to some reports in the literature, except for the higher proportion of patients with underlying pulmonary stenosis. Bacterial endocarditis prophylaxis should be emphasized in patients with RHD or pulmonary stenosis. 相似文献

ABSTRACT. A retrospective study of Swedish children with infective endocarditis (IE) during the period 1971-80 was made. Sixty-six instances were identified in 64 children (0.39 cases per 100000 children per year). Fifty (78%) had a previously known heart disease. Most commonly this was a ventricular septal defect and tetralogy of Fallot. Seventy-one percent had positive blood cultures. Streptococcus viridans and Staphylococcus aureus were most commonly isolated. Twenty-two percent of the children had undergone previous cardiac surgery. One case closely followed cardiac surgery and in only nine children could a definite port of entry of infection be demonstrated. 相似文献

Brain abscess is an uncommon intracranial suppurative infectious disease, especially in children. The clinical presentation, treatment and outcome of 75 children with brain abscesses admitted to the Department of Pediatric Infectious Diseases at Hacettepe University Faculty of Medicine were retrospectively analyzed. Seventy-five cases of brain abscess within a 28-year period were included in this study. Fever and headache were the most common presenting symptoms. Cyanotic congenital heart disease was the most common predisposing factor. The most common pathogen was Streptococcus spp. Although congenital heart disease remained the most common predisposing factor for development of intracerebral abscess, the rate of immunocompromised diseases as a predisposing factor of brain abscess has increased in recent years, and better management of otogenic infections also influences the prevalence of the disease. 相似文献

From 1978 through 1987, thirteen pediatric patients aged 14/12 years to 16/12 years were hospitalized for infective endocarditis (IE). Ten cases presented as acute septicemia with modification or development of a murmur and/or heart failure. Three patients had subacute endocarditis. Prior to the endocarditis, ten patients had recognized heart disease, whereas three had no known cardiac abnormality. The organism was recovered in seven cases, from blood cultures in six cases (3 Staphylococcus aureus, 1 group D streptococcus, 1 Staphylococcus albus, and 1 Salmonella typhi) and from a prosthesis in one case (Corynebacterium). Echocardiography confirmed the diagnosis in every patient except the one that had a prosthesis. Although all the patients received parenteral antimicrobial therapy, selected according to bacteriologic data when available, complications developed in every case, including heart failure in nine patients. Three children died, eight underwent valve replacement or repair once the infection was under control, and two have residual valvular disease. This study confirms that, in pediatric patients, the prognosis of IE remains severe despite advances in antimicrobial therapy and the contribution of echocardiography. 相似文献

BACKGROUND: Infective endocarditis (IE) is still one of the major complications of congenital heart disease and, therefore, prevention has always been an important issue. But there has been no large scale investigation of IE in Japan. METHODS: Clinical and microbiological features in 183 patients with congenital heart diseases complicated with infective endocarditis (IE), which were treated in our institute in the last 28 years, were reviewed. RESULT: During the period, the age distribution of the patients shifted to an older age; 80% were older than 15 years in the latest 7 year period. In the underlying diseases more complex conditions increased, such as the post Rastelli operation. Dental or oral diseases were the major preceding events and Streptococcus was the major pathogen throughout the study periods in the data. CONCLUSION: The result indicates the importance of continuing education for the prevention of IE and oral hygiene especially in adult patients with a risk for IE. 相似文献
