Periannular complications in infective endocarditis involving prosthetic aortic valves.

The periannular extension of infection in prosthetic valve endocarditis (PVE) is a serious complication of infective endocarditis associated with high mortality. Periannular lesions in PVE occasionally rupture into adjacent cardiac chambers, leading to aortocavitary fistulae and intracardiac shunting. It is unknown whether the prognosis of patients with aortocavitary fistulae is worse than that of those with nonruptured abscesses.

Periannular complications in infective endocarditis involving native aortic valves.

The extension of infection in native valve infective endocarditis (IE) from valvular structures to the periannular tissue is incompletely understood. It is unknown, for example, whether the prognosis of patients with aortocavitary fistulae is worse than that of those with nonruptured abscesses. The aims of this study were to determine the distinct clinical characteristics of patients with aortocavitary fistulae and nonruptured abscesses in native valve IE and to evaluate the impact of fistulization on the outcomes of patients with native aortic valve IE complicated with periannular lesions.

Aorto-cavitary fistulous tract formation in infective endocarditis: clinical and echocardiographic features of 76 cases and risk factors for mortality.

Aims: To investigate the clinical features, echocardiographic characteristics, management, and prognostic factors of mortality of aorto-cavitary fistulization (ACF) in infective endocarditis (IE). Extension of infection in aortic valve IE beyond valvular structures may result in peri-annular complications with resulting necrosis and rupture, and subsequent development of ACF. Aorto-cavitary communications create intra-cardiac shunts, which may result in further clinical deterioration and haemodynamic instability.

Mycobacterium chelonae tenosynovitis of the hand.

Objective: Tenosynovitis of the hand due to atypical mycobacteria is an uncommon condition. We present a case of tenosynovitis of the hand due to Mycobacterium chelonae in a patient without a recognized penetrating injury, who was treated successfully with clarithromycin and antituberculous medications and without debridement. We reviewed the available literature to summarize the experience with this infectious entity.

[Liver transplantation in patients with HIV infection: a reality in 2004].

According to current estimates, there are 60,000 to 80,000 HIV and HCV coinfected individuals in Spain, and 5,000 to 10,000 HIV and HBV coinfected individuals. Among these patients, 10% to 15% have liver cirrhosis. Thus, end-stage liver disease is one of the major causes of death in our country.

Liver transplantation without steroid induction in HIV-infected patients.

Until recently, human immunodeficiency virus (HIV) infection was considered an absolute contraindication for liver transplantation in Spain. We present the first 4 cases of liver transplantation (LT) carried out in our center in patients infected with HIV and coinfected by the hepatitis C virus (HCV), immunosuppressed with cyclosporine A (CyA) and basiliximab, but without steroids. The 4 patients were male, with a mean age of 38.
