We retrospectively reviewed 55 episodes that fulfilled criteria for Staphylococcus aureus endocarditis in 50 drug addicts. The most common presenting symptoms were fever(90%), chest pain(58%), and cough(43%). All patients had evidence of right-sided heart involvement, and a murmur of tricuspid insufficiency was noted in 42%. Evidence of left-sided heart involvement was present in only 5%. The most helpful laboratory aid in facilitating an early clinical diagnosis of endocarditis was the chest x-ray film. Roentgenographic evidence of septic pulmonary emboli was present in 67% of initial chest films and eventually in 87% of all cases. All but five patients completed at least four weeks of intravenous antibiotic therapy. No patients required cardiac surgery and there were no deaths. The apparent predilection of S aureus for the right side of the heart and infrequent left-sided involvement may explain why addicts with endocarditis have a favorable response to antibiotic therapy.

A 29 year old man experienced exertional dyspnea and coughing 3 1/2 years after insertion of a Brauwald-Cutter aortic valve prosthesis. Clinical examination suggested pulmonary arterial hypertension, and cardiac catheterization revealed a saccular lesion apparently arising from the left ventricular outflow tract and producing compression of the right pulmonary artery. Origin from the left ventricular outflow tract just under the aortic ring was confirmed at operation. The lesion apparently arose from an anular excavation related to previous endocarditis with abscess formation. Reported cases of similar aneurysmal lesions are briefly reviewed, and other known causes of the pulmonary arterial compression syndrome are discussed.

Four patients with infective endocarditis caused by Actinobacillus actinomycetemcomitans seen at the National Taiwan University Hospital between January 1985 and December 1990 are reported. There were two men and two women with a mean age of 40 years. Three had had a xenograft replacement, the other one had prolapse of mitral valve. Carious teeth were noted in two. The most common presenting symptoms were fever, cough, dyspnoea, and weight loss and the duration of symptoms before diagnosis varied from 2 weeks to 2 months. Peripheral stigmata of endocarditis were not present in any patient. Laboratory investigation revealed haematuria and anaemia in three patients, and elevated erythrocyte sedimentation rates in all four. None had leucocytosis. Echocardiography was performed more than once for each patient and vegetation was demonstrated in only one. Blood culture became positive after 7-10 days of incubation. One of the isolates was resistant to penicillin. The diagnosis was delayed due to the indolent clinical course, non-specific presentation, and the slow growth of the organism. However, all patients were cured clinically and bacteriologically after 6 weeks of intravenous antibiotic therapy which included penicillin, cefamandole, chloramphenicol, or aztreonam, with or without an aminoglycoside. All patients were free of evidence of recurrence after 6-25 months of follow-up.

Before the development of echocardiography, cardiac disease in the horse was diagnosed if a loud heart murmur (grade III-IV/VI or louder) and clinical signs of congestive heart failure (coughing, edema, venous distention, jugular pulsations) were detected on physical examination. Arrhythmias that persisted during and after exercise also indicated cardiac disease, which could be characterized electrocardiographically. Electrocardiography, thoracic radiography, angiography, cardiac catheterization, and oximetry could add only small pieces of information about the heart. M-mode echocardiography provided the first "window" with which to evaluate the heart and its intracardiac structures, albeit an ice-pick one-dimensional view. With M-mode echocardiography, the diameter of the aorta at the valves, the left ventricle, right ventricle, and left atrial appendage, as well as the thickness of the interventricular septum and left ventricular free wall, could be measured. Motion and thickness of the tricuspid, mitral, and aortic valves could be assessed, but only in a one-dimensional plane. Two-dimensional echocardiography provided an added dimension, resulting in visualization of all the intracardiac structures, aorta, and pulmonary artery. Two-dimensional echocardiography became the diagnostic technique of choice for the evaluation and characterization of congenital cardiac disease in critically ill neonates, as well as in adult horses. Two-dimensional echocardiography also improved the ability to diagnose valvular regurgitations, characterize valvular lesions (bacterial endocarditis, ruptured chorda tendineae), myocardial function (segmental wall motion abnormalities), atrial size, mass lesions (endocarditis, neoplasia, and thrombi), and pericardial effusion. Information about blood flow was obtained using contrast echocardiography but was limited to certain cardiac abnormalities (congenital cardiac defects and tricuspid regurgitation). This information about blood flow was limited to the detection of positive or negative contrast jets. Comprehensive information about blood flow was lacking until the application of Doppler echocardiography to equine cardiology. Pulsed-wave and color flow Doppler echocardiography resulted in precise localization of the abnormal blood flow and semiquantitation of the shunt flow or regurgitant jet. Color flow Doppler echocardiography sped up the localization and semiquantitation of the jet in many instances and provided some information about blood flow velocity in the enhanced and variance modes. The peak velocity of jets can be determined using continuous-wave Doppler echocardiography. This value then can be used to estimate pressure difference between cardiac chambers or to calculate cardiac output noninvasively if angles parallel to flow can be obtained. Thus, information about cardiac size, function, and blood flow can be combined to diagnose cardiac disease in horses and to formulate a prognosis for life and performance.

Bacterial endocarditis of the tricuspid valve was diagnosed in a cow with weight loss, reduced milk production, and intermittent fever. Clinical signs of disease included jugular and mammary vein pulses, tachycardia, large cardiac silhouette, and grade-III/V holosystolic murmur. The diagnosis was also supported by echocardiographic findings and isolation of Streptococcus viridans from blood samples. The cow was treated with penicillin, furosemide, acetylsalicylic acid, heparin, and potassium chloride and survived 14 months after the diagnosis, producing 1 live calf and 4 viable embryos. The cow's heart rate exceeded an upper normal limit of 80 beats/min during most of the initial 4 months of treatment. Additional clinical signs of disease that were observed during treatment included diarrhea, ventral edema, and coughing. General medicine and cardiology textbooks have previously minimized the potential benefits of anticoagulant use in cases of septic endocarditis. The advent of routinely performed embryo transfer procedures may make treatment of endocarditis feasible in cattle with exceptional genetic merit.

The characteristics features of right-sided endocarditis are summarized in this case report of a 30-year-old female admitted with a history of high grade, continuous, fever, breathlessness, and dry cough over a 10-day period. The patient had had an incomplete abortion 15 days earlier for which dilatation and curettage was performed. On examination, the patient was toxic, febrile with a pulse of 118/minute and respiration 36/minute. Her blood pressure was 110/70 mm Hg. There was soft, tender hepatomegaly and soft splenomegely. There also were scattered coarse crepitations over both lungs. The vaginal examination revealed posterior fornicial bogginess and tenderness. Urine and cervical pus swab showed growth of klebsiella. The blood culture was negative. A plan chest X-ray revealed multiple, small, basal, pulmonary infiltrates. Posterior colopuncture revealed a small quantity of clear, yellowish fluid. Abdominopelvic ultrasonography revealed an ill-defined haziness in the parauterine region. The patient was treated with ampicillin, gentamycin, and metronidazole, but she continued to deteriorate. An urgent exploratory laparotomy was performed. The patient died on the 2nd postoperative day. The autopsy findings revealed that the heart was normal in size and shape. The tricuspid valve showed a large vegetation projecting into the ventricle. Microscopic examination revealed polymorphonuclear infiltration with clumps of gram-negative bacillifocal areas of myocarditis also were seen. In lungs the right lower lobe showed a small, hemorrhagic infarct. Both the liver and spleen were congested. Kidneys showed multiple petechiae on the external surface and on the cut section. Endocarditis during pregnancy may be because of perinatal infections, urinary tract infection, or septic thrombophlebitis of pelvi veins. Septic abortion of pelvic infection secondary to IUD also can provide portal of entry for bacteria. The common organisms are streptococcus, staphylococci, and occasionally bacteroides and gram negative bacilli. Clinical suspicion of right-sided endocarditis is justified in any patient with prolonged fever, cough, pleuritic pain, tachycardia, and multiple pulmonary infiltrates. Heart murmurs are usually absent and if present are soft and may be heard at atypical sites.

The clinical findings during a major epidemic of Q-fever which affected 415 people in the Val de Bagnes (Valais, Switzerland) in the autumn of 1983 are reported. Q-fever symptoms were evident in 191 cases but inconspicuous or absent in 224 cases. The symptoms most frequently reported were prolonged high fever, headaches, severe exhaustion, loss of appetite, cough and myalgia. Amongst disorders which accompany acute Q-fever, pneumonia and granulomatous hepatitis are very frequent, while myopericarditis and glomerulonephritis are less frequently observed. Endocarditis, a later complication of Q-fever, is a severe illness which more frequently affects patients with underlying valvular lesions. New serological techniques now permit more rapid and more accurate diagnosis of both acute and chronic Q-fever.

Branhamella catarrhalis--a Gram-negative diplococcus--differs biochemically from other Neisseriaceae and possesses a specific protein with antigenic properties. Although scattered cases of meningitis and endocarditis have been reported since 1907, B. catarrhalis has been considered a non-pathogenic, pharyngeal commensal. However, relatively recent reports have shown B. catarrhalis to play a significant role in the etiology of otitis media and bronchopulmonary infections. Some reports also indicate a pathogenic role in sinusitis and longstanding cough in children, and in acute laryngitis in adults. B. catarrhalis is susceptible to co-trimoxazole, erythromycin, cephalosporins and tetracyclines. Most strains are also susceptible to penicillin, but the frequency of beta-lactamase producing B. catarrhalis has increased from 4% to 25% during the last six years (Sweden). First choice antibiotics in infections with penicillin-resistant strains would be erythromycin and co-trimoxazole.

Your recent lead article on toxic shock and tampons (November 1, p. 1161) prompts me to report a case of pelvic infection and staphylococcal septicemia 8 days after the insertion of a Lippes loop. Pelvic infection is a recognized complication of IUDs; although there have been 2 reports of endocarditis occurring in susceptible patients following the insertion of an IUD, septicemia is rare. A previously healthy 31-year old married woman had a loop inserted at a family planning clinic. 3 days later she developed sweating, vomiting, confusion, and cough and during the following 48 hours became disoriented with hallucinations. She was referred to the hospital with suspected encephalitis and on admission was febrile (38.8 degrees Celsius) and stuporose but responded to simple commands. Blood pressure was 95/60 mmHg but there were no other abnormal signs. Hemoglobin was 12.2 g/dl, white blood count 4.0x109/1 (80% neutrophils), erythrocyte sedimentation rate 70mm in the 1st hour; cerebrospinal fluid normal. Chest x-ray examination revealed patchy consolidation in the upper lobes of both lungs and an electroencephalogram showed bilateral nonspecific abnormality. 3 blood cultures taken on admission yielded penicillin-resistant Staphylococcus aureus. She was treated with high-dose intravenous cloxacillin and 24 hours after starting the antibiotic had improved markedly and the IUD was removed. Culture from the coil and also from a high vaginal swab yielded Staph aureus with a similar antibiogram to that of the organism cultured from the blood. Subsequent recovery was uneventful, although repeat chest x-ray examination showed small abscess cavities in the upper lobes of both lungs. The patient was discharged 4 weeks after admission and serial chest radiographs have confirmed complete resolution of the pneumonia and abscesses. There is little doubt that this patients' septicemia with lung abscess formation and encephalopathy originated in the genital tract. The patient was both toxic and shocked but was different from patients with the recently described toxic shock syndrome in that her blood culture was positive for Staph aureus. The case provides another example of the importance of this organism as a cause of infection associated with the insertion of foreign bodies into or through the vagina.

In patients admitted to the hospital with community-acquired pneumonia, intravenous antimicrobials can be safely switched to oral administration when the patient shows evidence of early clinical improvement. In our institution, patients are switched to oral antibiotics when: (A) cough and respiratory distress are improving, (B) patient is afebrile for at least 8 h, (C) the white blood cell count is returning toward normal, and (D) there is no evidence of abnormal gastrointestinal absorption. Patients with respiratory infections of unknown etiology are switched to an oral antibiotic with the same spectrum of activity as the intravenous empiric antibiotic. Combining our prospective clinical studies, we have patient outcome data for more than 150 patients admitted to the hospital with community-acquired pneumonia, who were treated with switch therapy. The clinical cure rate was 99.3%. The total hospital savings for 1994 based on the 80 patients with community-acquired pneumonia who were treated with switch therapy was $114,080. Discontinuation of intravenous lines will decrease the patient's risk for local cellulitis, abscess formation, septic thrombophlebitis, line sepsis, and endocarditis. The early hospital discharge associated with switch therapy will decrease the patient's risk for other nosocomial infections such as urinary or respiratory tract infections. Switch therapy is associated with a clinical cure rate that is equivalent to conventional therapy. In the area of cost-effective use of antibiotics, switch therapy should be considered as one of the primary options for health care cost containment.
