Quentin Lisan, Ollivier Laccourreye, Pierre Bonfils
OBJECTIVES: Sinonasal inverted papillomas (SIP) present a potential for recurrence years after the surgery, but most studies report short-term follow-up, and risk factors for recurrence are still debated. Furthermore, several classifications are described, and no consensus exists regarding which one should be used. The aims of this study were to report our long-term results, investigate for potential risk factors for recurrence, and compare the existing 8 staging systems. METHODS: Over a 28-year period, 110 patients with a diagnosis of SIP were enrolled...

Anticonvulsant drugs are often used in the treatment of epilepsy. However, their therapeutic monitoring is often necessary in order to obtain an appropriate dose adjustment, due to the proximity between their therapeutic and toxic ranges. The aim of this study was to carry out the synthesis, characterization and use of restricted access carbon nanotubes (RACNTs) in an online method for the analyses of phenobarbital and carbamazepine and primidone from untreated human blood plasma by column switching liquid chromatography...

Cisplatin holds an illustrious position in the history of chemistry most notably for its role in the virtual cure of testicular cancer. Here we describe a role for this small molecule in cyanide detoxification in vivo. Cyanide kills organisms as diverse as insects, fish, and humans within seconds to hours. Current antidotes exhibit limited efficacy and are not amenable to mass distribution requiring the development of new classes of antidotes. The binding affinity of the cyanide anion for the positively charged metal platinum is known to create an extremely stable complex in vitro...

Previous studies in Jeddah, western Saudi Arabia, showed rotavirus (RV) prevalence around 40% in pediatric inpatients with gastroenteritis (GE) with a maximum level during cooler months. Currently, there are no data on impact of rotavirus vaccine (RVV) on RV-GE in Saudi Arabia. Therefore, this study was conducted to assess impact of RVV on incidence and severity of RV-GE in hospitalized pediatric patients; 3 years after introduction of RVV in Saudi immunization program (SIP) in January, 2013.This cross-sectional observational study included GE cases under 5 years of age admitted to 2 tertiary hospitals, in Jeddah, from October to December, 2015...

This study focused on the role of bioaccessibility in the phenanthrene (PHE) biodegradation in diffusely contaminated soil, by combining chemical and microbiological approaches. First, we determined PHE dissipation rates and PHE sorption/desorption isotherms for two soils (PPY and Pv) presenting similar chronic PAH contamination, but different physico-chemical properties. Our results revealed that the PHE dissipation rate was significantly higher in the Pv soil compared to the PPY soil, while PHE sorption/desorption isotherms were similar...

This paper introduces a novel bacterial identification assay based on thermal wave analysis through surface-imprinted polymers (SIPs). Aluminum chips are coated with SIPs, serving as synthetic cell receptors that have been combined previously with the heat-transfer method (HTM) for the selective detection of bacteria. In this work, the concept of bacterial identification is extended toward the detection of nine different bacterial species. In addition, a novel sensing approach, thermal wave transport analysis (TWTA), is introduced, which analyzes the propagation of a thermal wave through a functional interface...

Surface electromyogram-controlled powered hand/wrist prostheses return partial upper-limb function to limb-absent persons. Typically, one degree of freedom (DoF) is controlled at a time, with mode switching between DoFs. Recent research has explored using large-channel EMG systems to provide simultaneous, independent and proportional (SIP) control of two joints-but such systems are not practical in current commercial prostheses. Thus, we investigated site selection of a minimum number of conventional EMG electrodes in an EMG-force task, targeting four sites for a two DoF controller...

Eighteen lactating dairy cows were used to elucidate their preference for green, grey, or red troughs. The herd was managed under a rotational grazing system with ad-libitum access to water until 11:30 h. For 9 days, all cows were tested individually following the afternoon milking. Cows drank similar quantities, spent a similar amount of time drinking, and took a similar number of sips from the 3 trough colors (p > .05). In 75% of the tests, cows drank more than 95% of the test period from the same trough...

BACKGROUND & AIMS: There is growing interest in the use of bone marrow cells to treat liver fibrosis, however little is known about their anti-fibrotic efficacy or the identity of their effector cell(s). Sphingosine-1-phosphate (S1P) mediates egress of immune cells from the lymphoid organs into the lymphatic vessels; we investigated its role in the response of hematopoietic stem cells (HSC) to liver fibrosis in mice. METHODS: Purified (c-kit+/sca1+/lin-) hematopoietic stem cells (HSC) were repeatedly infused into mice undergoing fibrotic liver injury...

BACKGROUND: Sipuleucel-T (SIP-T), which functions by stimulating cancer-specific dendritic cells, prolongs survival in men with prostate cancer. Ipilimumab (IPI) achieved a borderline survival advantage in a large randomized trial. SIP-T and IPI are potentially synergistic. PATIENTS AND METHODS: Nine men with progressive metastatic castrate-resistant prostate cancer (mCRPC) were treated prospectively with SIP-T followed immediately by IPI with one of the following doses of IPI: 1 mg/kg at 1 week after SIP-T; 1 mg/kg at 1 and 4 weeks after SIP-T; or 1 mg/kg at 1, 4, and 7 weeks after SIP-T...

INTRODUCTION: The incidence of head and neck cancer (HNC) in the UK is rising, with an average of 31 people diagnosed daily. Patients affected by HNC suffer significant short-term and long-term post-treatment morbidity as a result of dysphagia, which affects daily functioning and quality of life (QOL). Pretreatment swallowing exercises may provide additional benefit over standard rehabilitation in managing dysphagia after primary HNC treatments, but uncertainty about their effectiveness persists...

INTRODUCTION: Fatigue has been identified as an outcome of concern following burn but is rarely captured in outcomes studies. We aimed to: (i) describe the prevalence, and predictors, of moderate to severe fatigue in the first 12 months following burn, and (ii) establish the association between fatigue and health-related quality of life and work outcomes. METHODS: Adult burns patients, admitted >24h, were recruited from five BRANZ sites. Participants were followed-up at 1-, 6-, and 12-months after injury using the Brief Fatigue Inventory (BFI), 36-item Short Form Health Survey (SF-36) and the Sickness Impact Profile (SIP)-work scale...

Proteins and peptides are key components of the labile dissolved organic matter pool in marine environments. Knowing which types of bacteria metabolize peptides can inform the factors that govern peptide decomposition and further carbon and nitrogen remineralization in marine environments. A (13)C-labeled tetrapeptide, alanine-valine-phenylalanine-alanine (AVFA), was added to both surface (normoxic) and bottom (hypoxic) seawater from a coastal station in the northern Gulf of Mexico for a 2-day incubation experiment, and bacteria that incorporated the peptide were identified using DNA stable isotope probing (SIP)...
