1/22. Staphylococcus capitis endocarditis: two cases and review of the literature.coagulase negative staphylococci are the principal cause of prosthetic valve endocarditis but are a rare cause of native valve infections. However, the incidence of native valve endocarditis is increasing. Staphylococcus capitis is a coagulase negative staphylococcus with the capacity to cause endocarditis on native heart valves. Two cases of native valve endocarditis caused by S capitis are presented; both in patients with aortic valve disease. The patients were cured with prolonged intravenous vancomycin and rifampicin and did not need surgery during the acute phase of the illness. Five of the six previously described cases of endocarditis caused by this organism occurred on native valves and responded to medical treatment alone.- - - - - - - - - - ranking = 1keywords = staphylococcus (Clic here for more details about this article) |
2/22. Smitten by a kitten.Mammalian bite wounds are commonly encountered in the emergency department. When patients come early (<8 hours after injury), local infection is not usually evident. At this stage, the issue of providing prophylactic antibiotic therapy arises. We report a complication of a cat bite to the hand in a previously healthy 32-year-old man. This patient did not seek medical treatment immediately after the cat bite, and distinct local infection did not develop. Nevertheless, his course was complicated with acute Staphylococcus aureus endocarditis. We discuss the common pathogens involved in a cat bite infection, including S aureus, and delineate the indications for prophylactic antibiotic therapy after a mammalian bite wound.- - - - - - - - - - ranking = 0.06912846372677keywords = aureus (Clic here for more details about this article) |
3/22. staphylococcus lugdunensis pulmonary valve endocarditis in a patient on chronic hemodialysis.We describe a case of staphylococcus lugdunensis pulmonary valve endocarditis in a 65-year-old woman on chronic hemodialysis and provide a review of previously reported cases. The patient presented with fever and altered mental status, but had no other localizing symptoms or signs; coagulase-negative staphylococcus (subsequently identified as S. lugdunensis) was isolated from two sets of blood cultures. Transthoracic and transesophageal echocardiograms showed a large (2.3 x 3.1 cm) vegetation on the pulmonary valve with moderate valvular insufficiency. The patient was treated with 6 weeks of antibiotic therapy and is stable 4 months following the completion of therapy; no surgical intervention was performed. Of the 28 previously reported cases of S. lugdunensis endocarditis, only 1 had previously survived with medical therapy alone. This is the 3rd case report of S. lugdunensis endocarditis in a patient on hemodialysis; the presumed portal of entry in this and previously reported cases was the vascular access device. endocarditis due to this organism is characterized by a high mortality, rapid tissue destruction, and a predilection for native valves. Because the clinical outcome is much more favorable with valvular replacement, speciation of the organism assumes great importance in defining the therapeutic approach. copyright copyright 1999 S.

4/22. Value of repeated multiplane transesophageal echocardiography in a patient with mitral valve ring abscess and left ventricular pseudoaneurysm.mitral valve ring abscess and ventricular pseudoaneurysm are rare complications of infective endocarditis. We describe the case of a 58-year-old man who was admitted to our hospital with sepsis caused by Staphylococcus aureus and in whom tricuspid and mitral valve endocarditis developed within 2 weeks. Despite widespread antibiotic therapy, the endocarditis proceeded to form a mitral valve ring abscess and a left ventricular pseudoaneurysm. The diagnosis was set by repeated multiplane transesophageal echocardiography and confirmed by heart surgery.- - - - - - - - - - ranking = 0.034564231863385keywords = aureus (Clic here for more details about this article) |
5/22. Pseudo-aneurysm of the aortic root in a patient with mechanical aortic prosthesis.The authors describe a case of an ex-intravenous drug user, who received mechanical valve prostheses in the aortic and mitral position for Staphylococcus aureus endocarditis and developed a pseudo-aneurysm of the aortic root with major peri-valvular regurgitation one year after surgery. The images of the transesophageal echocardiogram are presented.- - - - - - - - - - ranking = 0.034564231863385keywords = aureus (Clic here for more details about this article) |
6/22. Three cases of destructive native valve endocarditis caused by staphylococcus lugdunensis.Described here are three cases of acute native valve endocarditis due to the coagulase-negative pathogen staphylococcus lugdunensis with serious complications. Two of the three patients died despite optimal antibiotic therapy and cardiovascular surgery. These cases demonstrate the aggressive nature of S. lugdunensis and emphasize the importance of identifying coagulase-negative staphylococci to the species level and not considering the isolation of S. lugdunensis from normally sterile body fluids as contamination. On the contrary, when this organism is found in patients with endocarditis, early surgery should be considered. The possibility that this organism could be misidentified as S. aureus because of "autocoagulation" and that commercial identification systems may misidentify it as S. haemolyticus, S. hominis or S. warneri should also be remembered.- - - - - - - - - - ranking = 0.034564231863385keywords = aureus (Clic here for more details about this article) |
7/22. pulmonary valve endocarditis during puerperal sepsis.A case of pulmonary valve endocarditis caused by Staphylococcus aureus during puerperal sepsis in a female patient is reported. The M-mode and two dimensional echocardiographic finding are described. A review of the literature shows that this entity is rare. A large vegetation in the leaflet of the pulmonary valve was excised and the patient recovered after a full course of antibiotics.- - - - - - - - - - ranking = 0.034564231863385keywords = aureus (Clic here for more details about this article) |
8/22. Pacemaker-induced Staphylococcus aureus mitral valve acute bacterial endocarditis complicated by persistent bacteremia from a coronary stent: Cure with prolonged/high-dose daptomycin without toxicity.Continuous high-grade Staphylococcus aureus bacteremia suggests acute bacterial endocarditis (ABE), a protected focus, ie, an abscess, or a device-related infection. daptomycin was curative of S. aureus ABE and coronary stent-related bacteremia. Prolonged high-dose daptomycin therapy (12 mg/kg per day for 41 days) is not associated with any toxicity. Persistent S. aureus bacteremia in ABE should suggest myocardial or perivalvular abscess. If intracardiac abscess can be ruled out and there is no extracardiac source of the S. aureus bacteremia, then a device-related infection should be considered.- - - - - - - - - - ranking = 0.27651385490708keywords = aureus (Clic here for more details about this article) |
9/22. Multiresistant-MRSA tricuspid valve infective endocarditis with ancient osteomyelitis locus.BACKGROUND: Methicillin-resistant S. aureus (MRSA) with low susceptibility to glycopeptides is uncommon. CASE PRESENTATION: The case of a 50-year-old non-drug addict patient presenting with tricuspid valve infective endocarditis (IE) by MRSA resistant to vancomycin and linezolid is presented. There was response only to quinupristin/dalfopristin. He had a motorcycling accident four years before undergoing right above-the-knee amputation and orthopaedic fixation of the left limb. There were multiple episodes of left MRSA-osteomyelitis controlled after surgery and vancomycin therapy. MRSA isolated from the blood at the time of IE presented with the same profile than the isolated four years earlier. Sequential treatment with teicoplanin-cotrimoxazole and Linezolid associated to vancomycin--rifampicin--cotrimoxazole had no improvement. infection was controlled after 28 days of therapy with quinupristin/dalfopristin. CONCLUSION: The literature presents only a few cases of MRSA IE not susceptible to glycopeptides in not drug addicted patients. This case shows the comparison of a highly-resistant MRSA after previous S. aureus osteomyelitis treated with glycopeptides. This is the first description of successful treatment of resistant-MRSA IE of the tricuspid valve complicated by multiple pulmonary septic infarction with quinupristin/dalfopristin.- - - - - - - - - - ranking = 0.06912846372677keywords = aureus (Clic here for more details about this article) |
10/22. Infective endocarditis of native valve after anterior nasal packing.We present a case report of a patient who was previously treated for spontaneous epistaxis with a petroleum jelly gauze (0.5 in x 72 in) anterior nasal packing filled with an antibiotic ointment, along with prophylactic oral clindamycin. The patient presented with fever and hypotension 3 days after the nasal packing. Her blood cultures grew methicillin-resistant staphylococcus aureus and the transesophageal echocardiography showed vegetation on the atrial surface of the posterior mitral valve leaflet, confirming the diagnosis of bacterial endocarditis attributable to nasal packing. Several case reports discuss toxic shock syndrome after nasal packing, but none describe endocarditis of the native heart valves subsequent to anterior nasal packing. Current guidelines on endocarditis prophylaxis produced by the american heart association, European Cardiac Society, and British Cardiac Society together with published evidence do not recommend endocarditis prophylaxis for patients with native heart valves undergoing anterior nasal packing.- - - - - - - - - - ranking = 0.034564231863385keywords = aureus (Clic here for more details about this article) |
