From 1970 to 1990, 7564 patients with melanoma were seen at Duke University Cancer Center. Complete follow-up data were available in all patients. The estimated probability of a pulmonary metastasis developing 5, 10, or 20 years after initial diagnosis was 0.13, 0.19, and 0.30, respectively. Pulmonary metastases were documented in 945 patients (12%), these(More)
In order to construct a multivariate model for predicting early recurrence and cancer death for patients with stage I non-small cell lung cancer, 271 consecutive patients (mean age, 63 +/- 8 years) who were diagnosed, treated, and followed at one institution were studied. All patients were clinical stage I with head and chest/abdominal computed tomograms(More)
BACKGROUND Pectoralis flaps are frequently used to treat poststernotomy mediastinitis. We compared the outcomes of omental transfer, an alternative treatment for mediastinitis, with those of pectoralis flaps. METHODS Patients treated for poststernotomy mediastinitis with isolated omental flaps (n = 21) were compared with a group of consecutive patients(More)
BACKGROUND Post-sternotomy mediastinitis reduces survival after cardiac surgery, potentially further affected by details of mediastinal vascularized flap reconstruction. The aim of this study was to evaluate survival after different methods for sternal reconstruction in mediastinitis. METHODS Two hundred twenty-two adult cardiac surgery patients with(More)
BACKGROUND To identify the optimal use of anticoagulants after Carpentier-Edwards valve replacement, a retrospective study of all patients undergoing Carpentier-Edwards aortic (N = 378) or mitral (N = 370) valve replacement was done. METHODS AND RESULTS At the time of hospital discharge, 103 patients were managed with warfarin, 509 with aspirin alone, and(More)
To assess the value of intraoperative transesophageal echocardiography during cardiac valve surgery, 154 consecutive patients who had a valve operation in conjunction with pre- and postcardiopulmonary bypass transesophageal imaging were studied. Prebypass imaging yielded unsuspected findings that either assisted or changed the planned operation in 29 (19%)(More)
A retrospective analysis of 193 renal transplant recipients yielded 15 patients who developed pulmonary mycosis posttransplantation and one case in which mycotic lung infection existed at the time of transplant surgery. Agent responsible for infection included Nocardia asteroides in 8 cases, Asperigillus flavus in 5 cases, Cryptococcus neoformans in 4(More)
BACKGROUND The growth rate, or doubling time, of radiographically indeterminate pulmonary abnormalities is an important determinant of malignancy. Prospective calculation of doubling time, however, delays diagnosis and treatment. Positron emission tomography (PET) using the glucose analogue fluoride-18 fluorodeoxyglucose (FDG) measures the enhanced glucose(More)
BACKGROUND Sternal wound infection (SWI) remains a devastating complication after cardiac surgery, decreasing long-term and short-term survival. In treating documented SWI, negative pressure wound therapy (NPWT) reduces wound edema and time to definitive closure and improves peristernal blood flow after internal mammary artery (IMA) harvesting.
