David Graham, Gideon Lipman, Vinay Sehgal, Laurence B Lovat
The landscape for patients with Barrett's oesophagus (BE) has changed significantly in the last decade. Research and new guidelines have helped gastroenterologists to better identify those patients with BE who are particularly at risk of developing oesophageal adenocarcinoma. In parallel, developments in endoscopic image enhancement technology and optical biopsy techniques have improved our ability to detect high-risk lesions. Once these lesions have been identified, the improvements in minimally invasive endoscopic therapies has meant that these patients can potentially be cured of early cancer and high-risk dysplastic lesions without the need for surgery, which still has a significant morbidity and mortality...

Non-vestibular cranial nerve schwannomas (NVCNS) are rare lesions, representing <10 % of cranial nerve schwannomas. The optimal treatment for NVCNS is often derived from vestibular schwannomas experience. Surgical resection has been referred to as the first line treatment for those benign tumors, but significant complication rates are reported. Stereotactic radiosurgery (SRS) has arisen as a mainstay of treatment for many benign tumors, including schwanommas. We retrospectively reviewed the outcomes of NVCNS treated by SRS to characterize tumor control, symptom relief, toxicity, and the role of hypo-fractionation of SRS dose...

From the 1940s through 1977, at least 590,000kg of polychlorinated biphenyls (PCBs) were released into the Hudson River from General Electric manufacturing plants located in Hudson Falls and Fort Edward, New York. In 1984, the U.S. Environmental Protection Agency designated a nearly 322km reach as the Hudson River PCBs Superfund Site. Here we describe a Fish Health Assessment study, part of a Natural Resource Damage Assessment, that evaluated the prevalence of toxicopathic lesions in adult brown bullhead (Ameiurus nebulosus), smallmouth bass (Micropterus dolomieu), and yellow perch (Perca flavescens)...

In a ProteoChip‑based screening system and subsequent studies, serine‑aspartic acid‑valine (SDV) was demonstrated to specifically bind to integrin αvβ3. An SDV‑containing peptide could target the tumor vessel and it may be an effective replacement for molecular imaging of the tumor. In the present study, a hexapeptide, SDV‑glutamic acid‑cysteine‑glycine (ECG), was developed and evaluated its diagnostic performance as a tumor imaging agent in tumor‑bearing mice. The hexapeptide SDV‑ECG was synthesized using Fmoc solid‑phase peptide synthesis...

Focal segmental glomerulosclerosis (FSGS) is characterized by focal and segmental obliteration of glomerular capillary tufts with increased matrix. FSGS is classified as collapsing, tip, cellular, perihilar and not otherwise specified variants according to the location and character of the sclerotic lesion. Primary or idiopathic FSGS is considered to be related to podocyte injury, and the pathogenesis of podocyte injury has been actively investigated. Several circulating factors affecting podocyte permeability barrier have been proposed, but not proven to cause FSGS...

Small cell-like change (SCLC) is a rare prostate lesion which has been described in only two previous studies (total of eight cases). Its relation to possible neuroendocrine differentiation remained unclear. We evaluated 11 SCLC cases with immunohistochemistry and electron microscopy. SCLC was characterized by crowded hyperchromatic small nuclei with scant cytoplasm, rosette-like structures, finely granular chromatin with indistinct nucleoli, and lack of mitoses, apoptoses, and necroses. In nine cases, SCLC was admixed with high-grade cancer, and in two cases, it represented a separate intraductal process, spatially remote from a low-volume Gleason score 6 (grade group 1) cancer...

BACKGROUND: Chronic total occlusions remain one of the biggest challenges for interventional cardiologists and the high risk of restenosis and stent thrombosis is still a major problem. Drug-coated balloons showed favorable results for the treatment of in-stent restenosis and other lesion types. The aim of this study was to evaluate the feasibility and outcome of a drug-coated balloon only approach for chronic total occlusion. METHODS: We included 34 patients with a native chronic total occlusion treated only by drug-coated balloons...

Recent advances in the surgical treatment of early stage non-small cell lung cancer (NSCLC) have focused heavily on making procedures less invasive, less radical, and better tolerated. Advances in accuracy and increased utilization of cross-sectional imaging allows for diagnosis of smaller and more indolent tumors and preinvasive lesions. Similar to advanced disease, early-stage treatment is now being tailored to individual patients and their tumors. Sublobar resections are gaining acceptance as an oncologically equivalent approach to lobectomy in well-selected stage I patients...

INTRODUCTION: Human immunodeficiency virus (HIV) infection gradually destroys the body's immune system, which makes it harder for the body to fight infections. HIV infection causes a quantitative and qualitative depletion of CD4 lymphocyte count, which increases the risk of opportunistic infections. Thus, CD4 count is one of the key factors in determining both the urgency of highly active antiretroviral therapy (HAART) initiation and the need of prophylaxis for opportunistic infections...

BACKGROUND AND AIMS: We aimed to determine whether finite element analysis (FEA)-derived plaque structural stress (PSS) analysis can predict serial changes in atheroma volume, type, and tissue composition within a fibroatheroma-containing target segment. METHODS: Overall, 210 patients (210 untreated coronary artery lesions) underwent serial (baseline and 12-month follow-up) grayscale- and virtual histology (VH)-intravascular ultrasound (IVUS). Baseline PSS was assessed at the minimal lumen and at the maximum necrotic core (NC) sites...

Stem cell transplantation, which is based on the application of mesenchymal stem/stromal cells (MSCs), is a rapidly developing approach to the regenerative therapy of various degenerative disorders characterized by brain and heart failure, as well as skin lesions. In comparison, the use of stem cell transplantations to treat infertility has received less attention. One of the causes of miscarriages and fetal growth delay is the loss of the decidual reaction of endometrial cells. The present study modeled decidualization processes in pseudopregnant rats...

PURPOSE: The complexity of upper extremity (UE) behavior requires recovery of near normal neuromuscular function to minimize residual disability following a stroke. This requirement places a premium on spontaneous recovery and neuroplastic adaptation to rehabilitation by the lesioned hemisphere. Motor skill learning is frequently cited as a requirement for neuroplasticity. Studies examining the links between training, motor learning, neuroplasticity, and improvements in hand motor function are indicated...

Bacterial canker, caused by Xanthomonas citri subsp. citri (Xcc), is one of the most destructive diseases of citrus. The pectolytic enzymes produced by phytobacteria are important virulence factors involved in tissue maceration, electrolyte loss and cell death of host plants. In this study, the promoter activity of the pectolytic enzyme genes pel1, pel2, pel3, pglA, and peh-1 were investigated in Xcc XW19 strain using the β-glucuronidase (GUS) gene as a reporter. GUS activity expressed under the control of the pel1, pel3, pglA, and peh-1 gene promoters positively correlated with bacterial growth...

The current National Comprehensive Cancer Network (NCCN) Guidelines consider the role of 2-deoxy-2-(18)F-fluoro-d-glucose positron emission tomography/computer tomography (FDG PET/CT) in the evaluation of cholangiocarcinoma (CCA) as "uncertain," and have recommended contrast enhanced computed tomography (CECT) but not FDG PET/CT as a routine imaging test for CCA workup. We set out to compare the diagnostic performance of FDG PET/CT and CECT in patients with CCA. The retrospective study included patients with CCA who underwent FDG PET/CT and CECT within 2-month interval between 2011 and 2013 in our hospital...

A 46-year-old woman suddenly developed peripheral edema. Her massive proteinuria, hypoproteinemia, and renal biopsy findings yielded the diagnosis of minimal change disease (MCD). In addition, lung Mycobacterium avium infection was diagnosed according to a positive culture of her bronchoalveolar lavage fluid. The lung lesion was improved by anti-nontuberculous mycobacteria therapy. Surprisingly, her proteinuria also gradually decreased and she attained complete remission of MCD without any immunosuppressive therapy...
