Healthcare-associated infective endocarditis: a case series in a referral hospital from 2006 to 2011.

BACKGROUND: Healthcare-associated infective endocarditis (HCA-IE), a severe complication of medical care, shows a growing incidence in literature. OBJECTIVE: To evaluate epidemiology, etiology, risk factors for acquisition, complications, surgical treatment, and outcome of HCA-IE. METHODS: Observational prospective case series study (2006-2011) in a public hospital in Rio de Janeiro. RESULTS: Fifty-three patients with HCA-IE from a total of 151 cases of infective endocarditis (IE) were included. There were 26 (49%) males (mean age of 47 ± 18.7 years), 27 (51%) females (mean age of 42 ± 20.1 years). IE was acute in 37 (70%) cases and subacute in 16 (30%) cases. The mitral valve was affected in 19 (36%) patients and the aortic valve in 12 (36%); prosthetic valves were affected in 23 (43%) patients and native valves in 30 (57%). Deep intravenous access was used in 43 (81%) cases. Negative blood cultures were observed in 11 (21%) patients, Enterococcus faecalis in 10 (19%), Staphylococcus aureus in 9 (17%), and Candida sp. in 7 (13%). Fever was present in 49 (92%) patients, splenomegaly in 12 (23%), new regurgitation murmur in 31 (58%), and elevated C-reactive protein in 44/53 (83%). Echocardiograms showed major criteria in 46 (87%) patients, and 34 (64%) patients were submitted to cardiac surgery. Overall mortality was 17/53 (32%). CONCLUSION: In Brazil HCA-IE affected young subjects. Patients with prosthetic and native valves were affected in a similar proportion, and non-cardiac surgery was an infrequent predisposing factor, whereas intravenous access was a common one. S. aureus was significantly frequent in native valve HCA-IE, and overall mortality was high.

Adult rhabdomyoma of the larynx.

Introduction Rhabdomyoma is a rare benign tumor derived from skeletal muscles. Laryngeal rhabdomyomas are even rarer, with only approximately 40 reported cases in world literature. Laryngeal rhabdomyomas usually are seen as masses covered by mucosa. They are often solitary asymptomatic tumors, but symptoms such as hoarseness can occur. The radiologic features are usually those typical of benign neoplasms, showing well-delineated borders. The differential diagnoses for laryngeal masses include cysts, laryngoceles, and benign and malignant neoplasms. The diagnosis is usually made using histopathologic findings, but in some cases some difficulties can be found. Immunohistochemical staining is of great value in the differentiation of similar tumors. Treatment of rhabdomyoma is surgical excision. Objective To describe a case of rhabdomyoma of the larynx attended at Santa Casa de Misericórdia do Rio de Janeiro. Case Report A 35-year-old man presented with progressive hoarseness in the preceding year. Laryngoscopy showed a large submucosal tumor at the supraglottic region of the larynx. The neck computed tomography scan confirmed the submucosal mass, with distinct borders. The patient was taken to the operating suite, where endoscopic extirpation of the mass was performed. Initial histologic diagnosis was suggestive of paraganglioma, which was not confirmed by studies with immunohistochemical markers, and diagnosis was changed to adult-type rhabdomyoma. The patient recovered well. His voice returned to normal after 3 months. Discussion Although muscle tumors of the larynx are very rare, rhabdomyoma should be considered when there is a submucosal mass in the larynx.

Bartonella and Coxiella infective endocarditis in Brazil: molecular evidence from excised valves from a cardiac surgery referral center in Rio de Janeiro, Brazil, 1998 to 2009.

PCR was used to detect Coxiella burnetii and Bartonella spp in heart valves obtained during the period 1998-2009 from patients operated on for blood culture-negative endocarditis in a cardiac surgery hospital in Brazil. Of the 51 valves tested, 10 were PCR-positive; two were positive for Bartonella and one for C. burnetii.

Cardiac angiosarcoma.

Despite cardiac metastases are found in about 20% of cancer deaths, the presence of primary cardiac tumors is rare. Most primary tumors are benign, and malignant tumors comprise about 15%. We report a 21-year-old man with fever, dyspnea, and hemoptysis that was diagnosed with angiosarcoma of the right atrium and pulmonary metastasis. Patient was submitted to surgical tumor resection without adjuvant therapy and died four months after diagnosis.

Improvement in left ventricular dysfunction after surgical correction of mitral regurgitation.

OBJECTIVE: To evaluate whether left ventricular end-systolic (ESD) diameters < or = 51mm in patients (pt) with severe chronic mitral regurgitation (MR) are predictors of a poor prognosis after mitral valve surgery (MVS). METHODS: Eleven pt (aged 36 +/- 13 years) were studied in the preoperative period (pre), median of 36 days; in the early postoperative period (post1), median of 9 days; and in the late postoperative period (post2), mean of 38.5 +/- 37.6 months. Clinical and echocardiographic data were gathered from each pt with MR and systolic diameter > or = 51 mm (mean = 57 +/- 4mm) to evaluate the result of MVS. Ten patients were in NYHA Class III/IV. RESULTS: All but 2 pt improved in functional class. Two pt died from heart failure and infectious endocarditis 14 and 11 months, respectively, after valve replacement. According to ejection fraction (EF) in post2, we identified 2 groups: group 1 (n=6), whose EF decreased in post1, but increased in post2 (p=0.01) and group 2 (n=5), whose EF decreased progressively from post1 to post2 (p=0.10). All pt with symptoms lasting < or = 48 months had improvement in EF in post2 (p=0.01). CONCLUSION: ESD > or = 51 mm are not always associated with a poor prognosis after MVS in patients with MR. Symptoms lasting up to 48 months are associated with improvement in left ventricular function.

Cardiopatia reumática e endocardite infecciosa em paciente com síndrome de imunodeficiência adquirida / Rheumatic Heart Disease and Infective Endocarditis in a Patient with Acquired Immunodeficiency Syndrome

A 36-old-woman was admitted with an infectious syndrome, respiratory insufficiency and vasculitis. There was a history of chronic intravenous drug abuse, sexual promiscuity and rheumatic heart disease. She had HIV positive tests. The vasculitis and heart failure worsened and the patient died of stroke. At autopsy it was found histologic evidence of AIDS, rheumatic heart disease with Aschoff nodes, infective endocarditis with cerebral abscesses and thalamic infarction

Paciente do sexo feminino com 36 anos de idade, vida sexual promíscua e usuária de drogas endovenosas, com passado de cardite reumática, foi internada com síndrome infecciosa, insuficiência respiratória, insuficiência cardíaca congestiva e vasculite. A pesquisa para anticorpo anti-HIV foi positiva em teste realizado. Houve agravamento da vasculite e da insuficiência cardíaca e evolução para o óbito com acidente vascular cerebral. À necropsia constatou-se quadro anatomopatológico de síndrome de imunodeficiência adquirida (SIDA), cardiopatia reumática com nódulos de Aschoff e, ainda, endocardite infecciosa com abcessos cerebrais e infarto hemorrágico no tálamo.
