BACKGROUND: Failure modes and effects analysis (FMEA) is used for the identification of potential risks in health care processes. We used a specific FMEA - based form for direct referral for colonoscopy and assessed it for procedurerelated perforations. METHODS: Ten experts in endoscopy evaluated and computed the entire referral process, modes of preparation for the endoscopic procedure, the endoscopic procedure itself and the discharge process. We used FMEA assessing for likelihood of occurrence, detection and severity and calculated the risk profile number (RPN) for each of the above points...

REVIEW
Yael Naaman, Limor Goldenhersh, Alon Ben-Arie
During the last decade sentinel lymph nodes biopsy has become an essential part of primary surgical treatment in a number of malignancies including breast cancer, melanoma and head-and-neck malignancies. Dye or radioactive substances are injected at the primary tumor site, followed by pre-operative and intra-operative mapping. During surgery only positive lymph nodes are being dissected instead of a complete dissection of the lymphatic basin. The advantages of sentinel lymph nodes dissection are reducing the side effects of extensive lymph nodes dissection, while maintaining high detection rates and sensitivity in identifying cases with lymphatic tumor spread...

PURPOSE: The mitogen-activated protein kinase phosphatases (MKPs) are a family of dual-specificity phosphatases that inactivate MAPKs by dephosphorylation. Impairment of MKP-1 expression in insulin resistance has been suggested to affect the cardioprotective properties of insulin. We hypothesized that manipulation of its activity during myocardial ischaemia/reperfusion of control as well as insulin-resistant rats may affect the outcome. METHODS: Hearts from 16 week dietary induced obese Wistar rats and their age matched controls were isolated, perfused in the working mode and subjected to 15 min global ischaemia / 30 min reperfusion or 35 min coronary artery ligation/ 60 min reperfusion...

Norfloxacin is often found in wastewater treatment plants, groundwater, and even drinking water causing environmental concerns because of its potential undesirable effects on human health or aquatic ecosystems. However, conventional treatments cannot deal with norfloxacin efficiently. This work proposes an efficiently enzymatic degradation of norfloxacin by chloroperoxidase (CPO). 82.18% degradation efficiency of norfloxacin was achieved after 25 min reaction time at pH 5.0 with an enzyme concentration of 1...

Intracranial germ cell tumors differ in histology and location, and require different clinical management strategies. We characterized the imaging features that may aid pre-operative differentiation of intracranial germinomas and non-germinomatous germ cell tumors (NGGCTs). This retrospective study analyzed 85 patients with intracranial germ cell tumors and adequate preoperative or pretreatment MRIs between 2000 and 2013 at our institution. Pretreatment MRI characteristics, apparent diffusion coefficient (ADC) values, tumor histopathology, and patient outcomes were compared...

PURPOSE: Chronic kidney disease (CKD) can place restrictions upon biopsychosocial development in children; consequently, assessment of self-reported quality of life (QoL) is important in patient evaluations. This research aimed to evaluate a generic and renal-specific self-report QoL scale, assess children's attitudes towards living with CKD and propose an appropriate tool for future individual clinical use or departmental audit. METHODS: Seventy-one children (41 male, 30 female; mean age = 13...

We report initial experience with novel three-dimensional (3D) image fusion software for guidance of transcatheter interventions in congenital heart disease. Developments in fusion imaging have facilitated the integration of 3D roadmaps from computed tomography or magnetic resonance imaging datasets. The latest software allows live fusion of two-dimensional (2D) fluoroscopy with pre-registered 3D roadmaps. We reviewed all cardiac catheterizations guided with this software (Philips VesselNavigator). Pre-catheterization imaging and catheterization data were collected focusing on fusion of 3D roadmap, intervention guidance, contrast and radiation exposure...

The principle of respect for autonomy requires informing patients adequately and appropriately about diagnoses, treatments, and prognoses. However, some clinical cases may cause ethical dilemmas regarding telling the truth. Under the existence especially of certain cultural, social, and religious circumstances, disclosing all the relevant information to all pertinent parties might create harmful effects. Even though the virtue of telling the truth is unquestionable, sometimes de facto conditions compel physicians to act paternalistically to protect the patient/patients from imminent dangers...

Lynch syndrome (LS) is a genetic condition conferring an elevated risk of gastrointestinal, gynecologic and other malignancies, often before the age of 50. Current guidelines recommend prophylactic gynecologic surgery to manage inherited cancers for female mutation carriers. Data is lacking on women's quality of life following surgery. In this pilot study, we explored how women described their quality of life post-prophylactic gynecologic surgery and the factors that affected post-surgery experiences. A qualitative interview study was the chosen design...

The use of remote optical feedback systems represents a promising approach for minimally invasive, nerve-sparing laser surgery. Autofluorescence properties can be exploited for a fast, robust identification of nervous tissue. With regard to the crucial step towards clinical application, the impact of laser ablation on optical properties in the vicinity of structures of the head and neck has not been investigated up to now. We acquired 24,298 autofluorescence spectra from 135 tissue samples (nine ex vivo tissue types from 15 bisected pig heads) both before and after ER:YAG laser ablation...

BACKGROUND: Preclinical and clinical research suggest that the α1 receptor antagonist prazosin reduces alcohol consumption. Furthermore, clinical studies indicate a role for prazosin in treating Post-Traumatic Stress Disorder (PTSD) symptoms and a recent trial suggested that pre-treatment blood pressure (BP) predicts therapeutic response for prazosin in PTSD patients. Whether pre-treatment BP may predict response to α1 blockers in alcohol-dependent (AD) patients is unknown. We previously reported a randomized controlled trial (RCT) where doxazosin, an α1 receptor antagonist with a more favorable pharmacokinetic profile than prazosin, reduced drinks per week (DPW) and heavy drinking days (HDD) in AD patients with a high family history density of alcoholism...

This study shows the Western theorization and interpretation of aging, place and health are not well suited to a non-western case. The current generation of older Chinese has experienced the transition from a planned economy to a socialist market economy. Urban changes have taken place in various ways. This study explains the spatio-temporal processes of older people with their changing places by conducting in-depth interviews with 47 older people living at home in Beijing. Their generational consciousness and old place identities are deeply rooted in pre-reform Collectivism and shaped by socialist ideologies of the past...

Thermal paper contains potentially toxic additives, such as bisphenol A (BPA), as a common color developer. Because of its known endocrine disrupting effects, structural analogues to BPA, such as bisphenol S (BPS), D-8 and Pergafast 201, have been used as alternatives, but little is known about the presence and toxicological effects of alternatives other than BPS. In this study, thermal paper is screened by direct probe ambient mass spectrometry (rapid pre-screening method not requiring sample preparation) and by liquid chromatography (LC) with high resolution time-of flight (TOF-MS) mass spectrometry...

The North American signal crayfish (Pacifastacus leniusculus) has invaded freshwater ecosystems across Europe. Recent studies suggest that predation of macroinvertebrates by signal crayfish can affect the performance of freshwater biomonitoring tools used to assess causes of ecological degradation. Given the reliance on biomonitoring globally, it is crucial that the potential influence of invasive species is better understood. Crayfish are also biogeomorphic agents, and therefore, the aim of this study was to investigate whether sediment-biomonitoring tool outputs changed following signal crayfish invasions, and whether these changes reflected post-invasion changes to deposited fine sediment, or changes to macroinvertebrate community compositions unrelated to fine sediment...

OBJECTIVE: When eating solids, stage II transport (St2Tr) propels triturated food into the pharynx for bolus formation and storage before swallowing. Although the existence of St2Tr is acknowledged, the reason for its existence remains unclear. Understanding it may facilitate development of food appropriate for individuals with dysphagia. The purpose of this study was to explore how measures of duration of eating and swallowing affect the number of St2Tr cycles. DESIGN: Videofluorography was performed on 13 healthy subjects eating 6-g squares of banana, tofu, and cookies...
