PURPOSE To evaluate and compare the workers' perception of comfort and use aspects regarding two types of hearing protectors (shell and earplug), in three units from a lumbering company, with different implantation times for Hearing Preservation Programs. METHODS This is a cross-sectional study comparing 440 workers' perception of hearing protectors, from three companies in Paraná State (Braz...

791 pression of the optic nerve has also been recommend­ ed, but it should be performed within 24 hours and its effectiveness is not clear [3]. Papillary mydriasis occurring during the treatment of blow out fracture might indicate irreversible blindness, because it means that the ciliary ganglion or short ciliary nerves are injured [4]. The ciliary ganglion is located posterolateral to the glob...

This paper investigates how formal techniques can be used for the analysis and verification of hybrid systems [1,5,7,16] — systems involving both discrete and continuous behavior. The motivation behind such research lies in the inherent similarity of the hierarchical and decentralized control strategies of hybrid systems and the communication and operation protocols used for distributed systems...

AIMS The aim of this study was to evaluate and to compare the effect of two fluoride varnishes and one fluoride/chlorhexidine varnish on Streptococcus mutans and Streptococcus sobrinus biofilm formation, in vitro. STUDY DESIGN Standard acrylic discs were prepared and divided into groups based on the varnish applied to the disc surface: Fluor Protector, Bifluoride 12, and Fluor Protector + Cer...

The prevention of fractures amongst older people consists of (i) prevention and treatment of osteoporosis, (ii) prevention of falling and (iii) prevention of fractures using injury-site protection. As the great majority of hip fractures are caused by a sideways fall with direct impact on the greater trochanter of the proximal femur, one approach to prevention is the use of an adequately configu...

BACKGROUND The LMA Protector™ is the latest CE marked single use supraglottic airway device. This airway device provides access and functional separation of the respiratory and digestive tracts. There are two ports (male, female ports) to provide suction in the laryngeal region and insertion of the gastric tube. The aim of our study is to assess the ease of use, airway quality, device positioni...

OBJECTIVES To assess predictors of hip-protector use in nursing home residents under usual-care conditions and after intervention consisting of structured education of nurses and nursing home residents and provision of free hip protectors. DESIGN Nested cohort analyses within a cluster randomized, controlled trial with 18 months follow-up. SETTING Forty-nine nursing home clusters in Hamburg...

INTRODUCTION Among surgical oncology patients, incisional surgical site infection is associated with substantially increased morbidity, mortality and healthcare costs. Moreover, while adults undergoing pancreaticoduodenectomy with preoperative placement of an intrabiliary stent have a high risk of this type of infection, and wound protectors may significantly reduce its risk, no relevant studie...

CONTEXT Past studies of the efficacy of hip protectors to prevent hip fracture in nursing home residents have had conflicting results, possibly due to potential biases from clustered randomization designs and modest adherence to intervention. OBJECTIVE To determine whether an energy-absorbing and energy-dispersing hip protector would reduce the risk of hip fracture when worn by nursing home r...
