BACKGROUND Informal employment is common in developing countries, including Egypt. This type of employment may have significant consequences on mental health. OBJECTIVE To determine the prevalence and risk factors of common mental disorders and substance abuse among temporary hired hospital cleaners. METHODS A cross-sectional study was conducted on 242 adult temporary cleaners and 209 perma...

Although whiplash is a common cause of disability, there is usually no demonstrable pathology and this leaves scope for moral hazard in claims for loss of earnings. Using weekly data about temporary disability, prescription drug purchases and the use of health services during 1996-2007, we examine the effects of a Danish 2002 reform that extended the period where whiplash claimants could get co...

BACKGROUND AND PURPOSE The significance of brain temperature to outcome in cerebral ischemia is recognized. Numerous variations of depth, duration, and delay of cooling have been studied in animal models. It is important to become familiar with these studies to design appropriate clinical trials. With that in mind, a critical review of the pertinent literature is presented, taking into consider...

B options allow bidders to instantly purchase at a specified price an item listed for sale through an online auction. A temporary buyout option disappears once a regular bid is submitted, whereas a permanent option remains available until it is exercised or the auction ends. Such buyout price may be static and remain constant throughout the auction, or dynamic and vary as the auction progresses...

OBJECTIVES This study aims to investigate the effect of primary surgery on the morbidity of reoperative thyroid surgery. PATIENTS AND METHODS Fifty-seven patients (14 male, 43 female; mean age 41 years; range 21 to 70 years), who underwent reoperative thyroid surgery in our clinic between January 2007 and January 2012 were retrospectively analyzed in terms of vocal cord paralysis, temporary o...

The indication for prophylactic temporary and permanent pacing during acute myocardial infarction (MI) complicated by bundle branch block is high risk of progression via a Type II pattern to second or third degree (high degree) AV block during hospitalization or follow-up. In this study, determinants of high degree AV block during hospitalization and sudden death or recurrent high degree block ...

For some patients diagnosed with rectal cancer, surgery will involve the creation of a temporary or permanent ostomy. When the colostomy is located in the sigmoid or descending colon, regulation of fecal output can occur through irrigation, a procedure that involves instilling fluid into the bowel to flush out gas and fecal material. When successfully used, irrigation can prevent fecal output b...

Mortality following permanent occlusion of both common carotid arteries decreases as the time between the first and second occlusions increases in Fischer 344 rats. Our goal was to examine the possibility that collaterals develop after unilateral carotid artery occlusion. During temporary occlusion of both carotid arteries in nine ketamine-anesthetized male rats, mean +/- SEM blood flow in both...

An Innovative Simulation Environment for Cross-Domain Policy Enforcement Lifeng Wang, Zhengping Wu Department of Computer Science and Engineering University of Bridgeport, Bridgeport, CT Policy-based management is necessary for cross-domain organization collaborations and system integrations. In reality different systems from different organizations or domains have very different high-level pol...

Corneal hydration and protection can be achieved through increased lubrication or decreased evaporation. Hence, an important therapeutic strategy to corneal desiccation involves occlusion of the lacrimal drainage system in order to decrease tear outflow and provide additional ocular surface hydration. Three general approaches can be used: temporary, reversible, or permanent occlusion of the lac...
