BACKGROUND The optimum treatment of prostate cancer recurrence following radiation therapy (RT) remains controversial due to the lack of long-term data. OBJECTIVE Our aim was to review the survival of patients who underwent salvage cryotherapy to the prostate gland for biopsy-proven recurrent prostate cancer and establish prognostic indicators. DESIGN,(More)
BACKGROUND AND PURPOSE Widespread introduction of robot-assisted laparoscopic radical prostatectomy (RALRP) has led to multiple surgeons going through the learning curve (LC). One of the recommendations for surgeons on the LC for RALRP is to choose patients with smaller glands. We evaluated our LCs to determine whether prostate size influenced(More)
Nasopharyngeal secretions obtained from 94 children with acute respiratory illness were examined for the presence of respiratory syncytial virus (RSV), adenovirus, and influenza virus type A by virus culturing (virus isolation technique [VIT]), immunofluorescence assay (IFA), and enzyme-linked immunosorbent assay (ELISA). Similar results were obtained in at(More)
PURPOSE Treatment of lung cancer patients with antiangiogenesis agents is a new promising paradigm. Tumor cavitation is frequently noted in these patients, but the clinical significance of this finding has not been fully determined. Our purposes were to evaluate the frequency, imaging characteristics, and clinical outcome of patients receiving(More)
BACKGROUND As the clinical significance of chronic bronchitis among smokers without airflow obstruction is unclear, we sought to determine morbidity associated with this disorder. METHODS We examined subjects from the COPDGene study and compared those with FEV1/FVC ≥ 0.70, no diagnosis of asthma and chronic bronchitis as defined as a history of cough and(More)
BACKGROUND Low levels of physical activity (PA) are associated with poor outcomes in people with COPD. Interventions to increase PA could improve outcomes. METHODS We tested the efficacy of a novel Internet-mediated, pedometer-based exercise intervention. Veterans with COPD (N = 239) were randomized in a 2:1 ratio to the (1) intervention group (Omron(More)
Normal physiology relies on the organization of transmembrane proteins by molecular scaffolds, such as tetraspanins. Oncogenesis frequently involves changes in their organization or expression. The tetraspanin CD151 is thought to contribute to cancer progression through direct interaction with the laminin-binding integrins α3β1 and α6β1. However, this(More)
BACKGROUND Although T cells, especially CD8+, have been implicated in chronic obstructive pulmonary disease (COPD) pathogenesis, their role during acute exacerbations (AE-COPD) is uncertain. METHODS We recruited subjects with COPD and a history of previous AE-COPD and studied them quarterly to collect blood and spontaneously expectorated sputum while(More)
Chronic obstructive pulmonary disease (COPD) is a disease of aging in combination with genetic, environmental, and behavioral risk factors. Aging and many of these risk factors are shared with other diseases, and, as a result, it is not surprising that patients with COPD often have coexistent diseases. This review of COPD comorbidities uses a framework in(More)
BACKGROUND AND OBJECTIVES Mucocutaneous bleeding (MCB) is the main expression of inherited disorders of primary hemostasis. However, the relative prevalence of these disorders, their clinical differential diagnosis, and the proportion of patients with MCB of unknown cause (BUC) after an initial comprehensive laboratory testing are unknown.
