1/229. The Freestyle stentless bioprosthesis for prosthetic valve endocarditis.We report a case of methicillin-resistant staphylococcus aureus-induced prosthetic valve endocarditis, which was successfully treated with aortic valve replacement using the Freestyle stentless bioprosthesis. The total root and stentless design of this bioprosthesis allows for more radical removal of infected tissue and easier treatment for annular abscess, while requiring less prosthetic materials than a conventional prosthesis. This bioprosthesis thus seems to be a valuable option for active endocarditis.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
2/229. Echocardiographic features of an unusual case of aortic valve endocarditis.In a patient with aortic valve endocarditis a myocardial abscess, complete heart block and acute aortic regurgitation developed. echocardiography gave evidence of large aortic valve vegetations, and at operation vegetations were found to have destroyed the right coronary cusp and part of the noncoronary cusp. Following surgery the patient recovered. echocardiography may prove to be a useful noninvasive technique to aid in the timing of surgical therapy in patients with valvular vegetations.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
3/229. Listeria endocarditis causing aortic root abscess and a fistula to the left atrium.We report the case of a 74-year-old man who presented with endocarditis on a porcine aortic valve replacement. Five of six blood cultures grew listeria monocytogenes. Transoesophageal echocardiography demonstrated the presence of a cavity posterior to the aortic annulus, apparently communicating with the left atrium. The patient underwent successful aortic valve re-replacement. Listeria endocarditis is rare with only 58 reported cases in the literature and is associated with high mortality.- - - - - - - - - - ranking = 4keywords = abscess (Clic here for more details about this article) |
4/229. Atypical infective endocarditis.BACKGROUND: Although infective endocarditis has changed in the recent past as a result of microbiologic and risk factors, it continues to be clinically challenging. The disease is characterized by the formation of septic masses of platelets on the surfaces of heart valves. Several mechanisms can cause or contribute to the development of endocarditis. Although risk factors for infective endocarditis are well known, patients with atypical signs and symptoms continue to challenge us. methods: We describe a case report of a patient admitted to our inpatient service with back pain and presumed pyelonephritis. A medline literature search was conducted, using the key words "endocarditis," "back pain," and "bacterial," for the years 1986 to the present. RESULTS AND CONCLUSIONS: A 42-year-old woman with a history of intravenous drug abuse was admitted to the family practice service with back pain and pyelonephritis. She developed hypoxia and a new heart murmur and had continued fevers. blood cultures drawn in the emergency department grew methicillin-resistant staphylococcus aureus. A bone scan and magnetic resonance imaging led to the diagnosis of epidural abscess. What appeared to be a simple case of pyelonephritis with back pain became a case of infective endocarditis complicated by an epidural abscess.- - - - - - - - - - ranking = 2keywords = abscess (Clic here for more details about this article) |
5/229. Do not snog the dog: infective endocarditis due to capnocytophaga canimorsus.We present a case of prosthetic valve endocarditis and paravalvular abscess caused by the canine bacteria capnocytophaga canimorsus in a 63-year-old man, who made a habit of snogging his pet dog. capnocytophaga canimorsus can cause culture-negative endocarditis, therefore a high level of clinical awareness and the appropriate isolation techniques are important for making the diagnosis. Antibiotic therapy and properly timed excision of the infected focus are recommended.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
6/229. Endocardial abscesses in children: case report and review of the literature.The rarity of perivalvular abscesses arising as a complication of bacterial endocarditis in the pediatric population limits its recognition and awareness of its often malignant course. The diagnosis depends on a combination of clinical criteria, including persistent fever and bacteremia, the presence of an atrioventricular block and persistent embolic phenomenon, and transthoracic or transesophageal echocardiographic confirmation. Because of the infrequency of perivalvular abscesses in children, there is no consensus on a treatment strategy. Early detection and intervention with antibiotics and surgical debridement are recommended to decrease the morbidity and mortality associated with this disease. A case of a 14-year-old boy with an aortic root abscess is presented, along with review of other cases reported in the last 20 years in children in relation to risk factors, clinical features, diagnosis, therapy, and mortality.- - - - - - - - - - ranking = 7keywords = abscess (Clic here for more details about this article) |
7/229. cardiac tamponade: an unusual, fatal complication of infective endocarditis.Infective endocarditis still occurs in Western countries and so far, it has been an important medical problem. The spectrum of infective endocarditis complications may be extremely wide. We report two unusual cases of infective endocarditis complicated with heart rupture and pericardial effusion. In one case, the infective process spread from the aortic valve developing a sinus of valsalva aneurysm with subsequent aortic perforation. The perforation reached the right auricular epicardial region with subsequent epicardial rupture and hemopericardium. In the other patient, an infective process of the aortic cusps induced the formation of multiple abscesses in the left ventricle and in the right atrium. An annular abscess of the tricuspid valve was found. From the right atrium, an infected fistula spread through the atrial wall and perforated the epicardial surface of the right auricle. Aside from the rare occurrence of these complications in patients affected with infective endocarditis, these cases are of clinical interest because they raise the problem of the need of greater sensitivity to the diagnosis of endocarditis and proper diagnostic approach.- - - - - - - - - - ranking = 2keywords = abscess (Clic here for more details about this article) |
8/229. brucellosis: unusual presentations in two adolescent boys.Two boys presented with variable signs and symptoms of infectious disease that challenged diagnosis. One of the two patients had aortic valve vegetations and lower extremity aneurysms, and the other had calvarial osteomyelitis, epidural abscess, pleural effusions, and pulmonary nodules. Only after a battery of bacterial and fungal agglutination tests was the unsuspected diagnosis made in each of brucellosis from brucella canis.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
9/229. An unusual case of acquired ventricular septal defect as a complication of aortic valve endocarditis: echocardiographic delineation of multiple subvalvular complications in one patient.We describe a patient with unusual echocardiographic features of prosthetic aortic valve endocarditis. Transesophageal echocardiography in this patient demonstrated a large multiloculated aortic root abscess extending to mitral-aortic intervalvular fibrosa, a high acquired ventricular septal defect, paravalvular aortic regurgitation caused by aortic valve dehiscence, and anterior mitral valve leaflet perforation.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
10/229. Splenic abscesses caused by actinomyces meyeri in a patient with autoimmune hepatitis.We report a case of actinomycosis with uncommon localizations that was due to actinomyces meyeri. Although penicillin is the standard treatment for this condition, our patient was treated successfully with imipenem. actinomyces organisms are important constituents of the normal flora of mucous membranes and are considered opportunistic pathogens; these organisms may produce infection after local trauma, surgery, or aspiration. The mains forms of actinomycosis are cervicofacial, thoracic, and abdominal; most cases are due to actinomyces israelii, whereas other actinomyces species are occasionally implicated. actinomycosis usually occurs in immunocompetent persons, but may occur in persons with diminished host defenses.- - - - - - - - - - ranking = 4keywords = abscess (Clic here for more details about this article) |
