Staphylococcus capitis endocarditis due to a transvenous endocardial pacemaker infection: case report and review of Staphylococcus capitis endocarditis.

Objectives: Newer microbiologic methods to determine the species of coagulase-negative staphylococci (CoNS) have evolved which have shown that most endocarditis due to CoNS is caused by Staphylococcus epidermidis, and far fewer by Staphylococcus warneri and Staphylococcus lugdunensis.

Methods: The recent opportunity to successfully treat a patient with methicillin-resistant Staphylococcus capitis endocarditis secondary to an infected transvenous pacemaker led to a review of the literature relating to S. capitis endocarditis.

In the lung aerosol cyclosporine provides a regional concentration advantage over intramuscular cyclosporine.

Background: Acute rejection remains an almost universal complication among lung transplant recipients. Refractory rejection as well as chronic systemic immunosuppression is associated with significant morbidity and mortality. Recent studies suggest that aerosol cyclosporine may address these issues by effectively preventing acute cellular rejection while maintaining low systemic drug concentrations.

Congenital Heart Surgery Nomenclature and Database Project: mitral valve disease.

The extant nomenclature for mitral valve disease is reviewed for the purpose of establishing a unified reporting system. The subject was debated and reviewed by members of the STS-Congenital Heart Surgery Database Committee and representatives from the European Association for Cardiothoracic Surgery. All efforts were made to include all relevant nomenclature categories using synonyms where appropriate.

Reoperative pulmonary thromboendarterectomy.

Background: Recurrent symptomatic pulmonary hypertension is uncommon after primary pulmonary thromboendarterectomy (PTE). We reviewed our experience with patients undergoing repeat PTE to determine the risk factors for recurrent disease, and the selection criteria, relative risks, and functional outcomes of reoperative PTE.

Methods: Since 1990, 13 of 870 (1.

Mixed hematopoietic chimerism induces donor-specific tolerance for lung allografts in rodents.

Mixed hematopoietic chimerism is a state in which bone marrow hematopoietic stem cells from two genetically different animals coexist. We investigated whether mixed hematopoietic chimerism, resulting from the transplantation of host and donor bone marrow into a lethally irradiated rat, would confer donor-specific tolerance to lung allografts. Recipient rats (Fisher or or Wistar Furth [WF]) were irradiated (1,100 cGy) and reconstituted with a mixture of T-cell-depleted syngeneic plus allogeneic bone marrow.
