Endocarditis secondary to Hemophilus parainfluenzae is an uncommon entity that appears to be increasing in frequency, perhaps due to improved laboratory isolation techniques. Although controversial, most of the published literature recommends a penicillin, with or without concomitant gentamicin, as definitive therapy. We report the first successful use of the third-generation cephalosporin ceftizoxime in an ampicillin-allergic patient. A 55-year-old white female was hospitalized after 5 days of experiencing fever, chills, nausea, and vomiting. A cardiac echocardiogram revealed a large mitral valve vegetation, and the patient was treated with intravenous ampicillin, gentamicin, and clindamycin. Two weeks after emergency mitral valve replacement the patient developed spiking fevers and a macular, erythematous rash while receiving ampicillin. Ceftizoxime was initiated and continued to complete a 4-week period of intravenous antibiotics. Follow-up at 14 months showed no further evidence of infection. Ceftizoxime appears efficacious in eradicating H. parainfluenzae in patients allergic to penicillin.

Patients usually provisionally diagnosed as having typhoid fever or pneumonia are regularly admitted to the Rietfontein Fever Hospital suffering from psittacosis. The main symptoms are intense headache, chills and fever and an irritating non-productive cough. Later most patients develop signs of pneumonitis most clearly seen on radiographic examination. An important clue to the diagnosis is a history of contact with birds, most often budgerigars and more recently cockatiels. The diagnosis may be confirmed by the isolation of Chlamydia psittaci, the causative organism, but more usually reliance is placed on the results of serological tests revealing the development of chlamydial antibodies. None of the patients in this series developed serious complications, but if not treated psittacosis sufferers may develop severe pneumonitis, hepatitis and gastro-enteritis; the mortality rate is up to 20%. A rare but fatal complication is chlamydial endocarditis, presenting with the signs and symptoms of subacute bacterial endocarditis, but giving repeated negative blood cultures. The illness responds specifically to treatment with tetracycline antibiotics within 48 hours. Chlamydial infections are widespread among avian species. In the RSA most cases of psittacosis have resulted from contact with budgerigars and cockatiels, but outbreaks have been associated with imported batches of birds including South American parrots and Australian finches, emphasizing the need for vigilance at seaports.

This communication concerns a case of endocarditis caused by Corynebacterium diphtheriae. The patient was a 35-year-old male drug addict who was brought to the hospital with fever, chills, and abdominal pain. Two days after admission, blood cultures were found to be growing gram-positive rods suggestive of diphtheroids. Repeated blood cultures grew the same organism, which was identified as a nontoxigenic strain of C. diphtheriae. The patient subsequently was identified as having acquired immune deficiency syndrome. Although isolates are divided into toxigenic and nontoxigenic strains, all isolates of C. diphtheriae should be considered potentially toxigenic. Because diphtheria generally is considered only of historic interest, few laboratories perform tests to identify it and instead report all isolates as "diphtheroids" or Corynebacterium. Because all isolates are potentially toxigenic, and because there is a large reservoir of nonimmunized people, laboratories must be alert to possible serious epidemiologic situations.

Based on the findings of 50 patients with infective endocarditis, 37 affecting the aortic, six the mitral and seven both the aortic and mitral valves, in addition to analysis of predisposing factors, prominent signs and symptoms distinctive for the clinical entity were assessed (Tables 1 to 3). Preexistent conditions such as aortic valve lesions including bicuspid aortic valve as well as mitral valve lesions including mitral valve prolapse were proven in 66%. Factors which may have compromised host defense mechanisms such as cachexia and chronic alcohol or intravenous drug abuse were present in isolated cases. In 38% of the patients, a diagnostic or therapeutic manipulation, suspected to have given rise to the bacteremia, antedated the onset of endocarditis. Malaise, fatigue and chills were the most frequent symptoms (Table 4). Fever and cardiac murmurs were observed in all patients, anemia and bacteremia in 74% of the patients, respectively (Tables 4 to 6). In blood cultures, the most common microorganisms were found to be hemolytic and nonhemolytic streptococci accounting for 65% of positive findings, followed by enterococci and gram-negative bacteria each with 14% respectively (Table 6). Congestive heart failure predominated among cardiac complications with its occurrence in 84% of the patients. Valvular ring or myocardial abscess, aortic or sinus of Valsalva aneurysm, occasionally with perforation, were found in 24% of our patients. Coronary embolism was documented in 6%; infection-associated pericarditis was observed only rarely (Table 7). Extracardiac complications involved the skin, central nervous system, spleen and kidneys, respectively, in 20 to 30% of the patients. Complications afflicting the eyes, lungs, gastrointestinal tract and the musculo-skeletal system were seen with a lesser frequency of 0 to 12% (Table 8). The diagnosis of infective endocarditis, rendered highly-probable by the constellation of fever, cardiac murmur, bacteremia and anemia, necessitates, however, confirmation through cardiac examinations. In this respect, electrocardiographic and radiologic findings are of limited value, although they may be useful in the detection of cardiac complications. In 6% of the patients, positive criteria for myocardial infarction were indicative of coronary embolism and, i 30%, atrioventricular or fascicular block suggested the presence of abscess formation (Table 9). As radiologic evidence of heart failure, 74% of the patients were found to have pulmonary vascular congestion (Table 10).(ABSTRACT TRUNCATED AT 400 WORDS)

Data of clinical examinations of 54 patients suffering from septic endocarditis are presented. Under examination there were patients admitted for this disease to a city hospital within a 5-year period. In 10 patients, the septic endocarditis was complicated with cerebral circulation disorders of the type of thromboembolism, subarachnoidal and hemispheral hemorrhages, mixed stroke, and cerebral vasculitis. Sometimes the cerebral circulation disorders preceded the development of septic endocarditis, and in such cases the diagnosis was difficult, especially in elderly patients with symptoms of cardiac insufficiency of other etiology. In such patients, the disease could be diagnosed correctly when the cerebral circulation disorder developed in the presence of a general infection (with fever, chills, and blood picture changes) and there were indications of frequently repeated thromboembolisms.

A 28-year-old man with a history of rheumatic heart disease, alcoholism and amphetamine abuse presented with severe left upper quadrant abdominal pain and persistent fever. He stayed at home for the previous two months due to intermittent dull lower abdominal pain, chills, fever and tarry stools without seeking medical help. A diagnosis of infective endocarditis with splenic infarcts and a renal infarct was made based on the echocardiographic and abdominal computer tomography scan findings. His clinical course was complicated by an acute inferior wall myocardial infarction and cerebral hemorrhage. Despite aggressive medical treatment, his condition deteriorated. One month later, his condition became more critical with pneumonia and intractable shock, and his family requested his discharge. He died soon after leaving the hospital.

A 26 year old female patient was admitted to our hospital because of septic temperatures and chills. In the patient's history renal insufficiency has been known for several years due to agenesia of the right and pyelonephritic renal congestion of the left kidney. Long lasting anorexia nervosa had been treated by psychotherapeutical interventions for years and when failing it necessitated repeated intravenous nutrition by central venous lines. The prominent symptom of the intravenously treated young woman was fever up to 39.7 degrees C and pneumonia, which was considered by the first treating clinic to be caused directly by diminished immunoreactivity in malnutrition and preuremia. The chest X-ray confirmed pneumonia and revealed multiple abscesses in both lungs (Figure 1). After being transferred to our intensive care unit the pathophysiological context became obvious. From inspection (positive jugular pulsation), from auscultation (holosystolic murmur at the left parasternal border) tricuspid incompetence due to infective endocarditis was suspected. This was confirmed immediately by TM and two-dimensional transthoracic echocardiography, which showed a large vegetation on the anterior tricuspid valve leaflet (Figures 2a and 2b). Tricuspid regurgitation was also ascertained by color flow echocardiography (Figure 2c). Several blood cultures were positive for staphylococcus aureus. Clinical and laboratory recovery was achieved by antibiotic therapy with vancomycin and cephtazidim for 3 months.(ABSTRACT TRUNCATED AT 250 WORDS)

We conducted a retrospective study to characterize the clinical course, microbiologic spectrum, and risk factors for endocarditis and for associated mortality in a large series of patients with documented pacemaker endocarditis. Using a computerized search through the medical records of 10 major hospitals in Israel from 1982 to 1992, and carefully reviewing the charts, we identified 44 patients with pacemaker endocarditis. The cases were categorized as definite (n = 25), probable (n = 12), or possible (n = 7) infective endocarditis based on strict case definition. Fever and chills were the most common symptoms. Increased ESR, leukocytosis, microscopic hematuria, and anemia were the most common laboratory findings. A relatively high proportion of the patients were diabetic. The most common source of endocarditis was infection acquired by the placement procedure or infection of the pacemaker pouch. Demographic, clinical, and laboratory features were similar to those of endocarditis patients of a similar age range without pacemakers, although the frequency of fever and chills was higher in our patients than in those patients and splenomegaly, vascular embolic phenomena, and new or changing murmurs were rare in our patients. The major pathogens were Staphylococcus aureus and Staphylococcus epidermidis, similar to other series of pacemaker-associated bacteremia and similar to the microbiologic findings of early prosthetic-valve endocarditis. However, this microbiologic profile is different from that of native-valve endocarditis. Although the present series did not show a statistically significant advantage to electrode removal over conservative treatment, when analyzed together with pooled data from other studies, it suggests that the surgical approach is preferable.(ABSTRACT TRUNCATED AT 250 WORDS)

A 26-year-old man who had suffered from intermittent chills and fever over a two month period was quite clear of heart or kidney involved developed acute deterioration of renal function. A new pansystolic murmur over the apex of the heart was heard on auscultation, and echocardiography clearly showed a vegetation about 0.7-0.9 cm in size on the atrial site of the mitral value. Laboratory investigation displayed normochromic anemia with negative Coombs' test. Immunological studies were positive for rheumatoid factor and circulating immune complex. High serum levels of erythrocyte sedimentation rate and C-reactive protein, nephritic sediment of urinalysis and negative blood cultures for bacteria, tuberculosis or fungus were also noted. Abdominal sonography showed normal kidney size, bilaterally. Renal biopsy revealed typical crescentic glomerulonephritis. After intravenous penicillin therapy for two weeks, the serum creatinine level recovered from 6.7 mg/dl to 2.0 mg/dl and circulating immune complex disappeared. In consideration of cardiac insufficiency and the potential risk for complications of the vegetation, the patient underwent mitral valve replacement. Four weeks after operation, all the abnormal data had resolved completely. These data suggested that infective endocarditis with rapidly progressive glomerulonephritis is curable by antibiotic therapy and surgical intervention.

Infection is an infrequently reported complication following septoplasty and septorhinoplasty. Among the recognized but rare infections are toxic shock syndrome, spinal osteomyelitis, meningitis, septic cavernous sinus thrombosis and endocarditis. A high index of suspicion is required to diagnose these infections early and thereby minimize morbidity and mortality. We present a case of endocarditis following septoplasty in a patient who had no identifiable preoperative risk factors but who experienced recurrent fever and chills postoperatively.
