The anti-granulocyte receptor-1 (Gr-1) mAb, RB6-8C5, has been used extensively to deplete neutrophils in mice and to investigate the role of these cells in host defense. RB6-8C5 binds to Ly6G, which is present on neutrophils, and to Ly6C, which is expressed on neutrophils, dendritic cells, and subpopulations of lymphocytes and monocytes. It is thus likely(More)
The phenotype of wound macrophages has not been studied by direct examination of these cells, yet macrophages recruited to sites of injury are described as alternatively activated macrophages, requiring IL-4 or IL-13 for phenotypic expression. This study characterized wound macrophage phenotype in the PVA sponge wound model in mice. Eighty-five percent of(More)
BACKGROUND There is controversy regarding the need for prophylactic level VI central node dissection in patients with low-risk papillary thyroid carcinoma (PTC). This study focuses on the incidence of persistent level VI nodal disease in low-risk PTC without prophylactic central node dissection. METHODS PTC was known at the time of thyroidectomy in 304 of(More)
In this study, we investigated the role of interleukin (IL)-1 signaling in wound healing. IL-1 receptor type I (IL-1R) knockout (KO) mice showed reduced fibrosis in both cutaneous and deep tissue wounds, which was accompanied by a reduction in inflammatory cellular infiltration in cutaneous but not in deep tissue wounds. There were no differences in either(More)
OBJECTIVE Esophageal cancer patients receiving induction chemoradiation to 41 Gy randomized to minimally invasive (MIS) esophagectomy have fewer postoperative pulmonary complications compared with those who underwent open procedures. We evaluated the feasibility of MIS Ivor Lewis esophagectomy in patients treated with induction chemoradiation to 50.4 Gy. (More)
BACKGROUND In colorectal cancer, the involvement of regional lymph nodes with metastasis is an established prognostic factor. The impact of the number of positive nodes on patient outcome with stage IV disease is not well defined. METHODS A retrospective review was performed of 1,421 patients at two tertiary referral centers with stage IV colorectal(More)
BACKGROUND AND OBJECTIVE Our goal was to evaluate the different subtypes of mucosal melanoma and describe specific variables that predict outcomes. METHODS Prospective review of two tertiary care center databases identified 76 mucosal melanoma patients; 73 with complete records were included. Demographic and clinical data were analyzed. Cox regression(More)
This article provides an overview of the approach to patients who may benefit from palliative care. While the article's details lend themselves to the treatment of complications secondary to advanced malignancies, the data herein can also be extrapolated to other chronic, terminal diseases. Guidelines for patient selection are discussed, using currently(More)
The role of Toll-like receptor 4 (TLR4) in the regulation of inflammation and fibrosis in sterile wounds was investigated in TLR4 signal-deficient (C3H/HeJ or TLR4(-/-) ) and control mice using the subcutaneously implanted polyvinyl alcohol sponge wound model. Total and differential wound cell counts 1, 3, and 7 days after injury did not differ between(More)
Fifty percent of patients with colorectal cancer will develop metastases at some time during their disease, with the liver being the most common site. Recent advances in the treatment of metastatic colorectal cancer have led to a change in treatment paradigm. What follows is a review of the surgical management of hepatic colorectal metastases responding to(More)
