This paper discusses the methodology used to determine the optimal ion-exchange column size to process all separate batches of feeds from acid mine drainage wastewater. The optimal design ensures the best utilization of resin material and therefore results in a minimum amount of spent resins. Ion exchanger materials have been studied for removing heavy metals from a metal bearing wastes. For th...

The populations, infrastructure and ecology of cities are at risk from the impacts of climate change which affect urban ventilation and cooling, urban drainage and flood risk and water resources. Built areas exert considerable influence over their local climate and environment, and urban populations are already facing a range of weather-related risks such as heat waves, water pollution and floo...

OBJECTIVE To determine what practices are used by hospitals to prevent ventilator-associated pneumonia (VAP) and, through qualitative methods, to understand more fully why hospitals use certain practices and not others. DESIGN Mixed-methods, sequential explanatory study. METHODS We mailed a survey to the lead infection control professionals at 719 US hospitals (119 Department of Veterans Af...

BACKGROUND Over the last decade, there has been a significant increase in the number of cutaneous abscesses. While there is general agreement that abscesses should be treated with incision and drainage, it is unclear whether systemic antibiotics should be routinely prescribed. OBJECTIVE To evaluate whether systemic antibiotics, when compared with a placebo, improve cure rates in patients with...

OBJECTIVE Although parenteral antibiotic treatment is a standard approach for tuboovarian abscesses, a significant proportion of patients fail therapy and require interventional radiology (IR) guided drainage. The objective of this study is to assess if specific clinical factors are associated with antibiotic treatment failure. STUDY DESIGN Retrospective medical record review of patients hosp...

Study Design Case report. Objective Incidental durotomy (IDT) is a common complication of spinal surgery. The use of collagen matrix graft along with hydrogel dural sealant is a common method of IDT repair. With this method, there have been several reported cases of detrimental dural sealant expansion in the literature. One case study reported an expansion rate greater than 300%; many report ne...

INTRODUCTION Deep neck space abscesses (DNAs) are relatively common otolaryngology-head and neck surgery emergencies and can result in significant morbidity with potential mortality. Traditionally, surgical incision and drainage (I&D) with antibiotics has been the mainstay of treatment. Some reports have suggested that ultrasound-guided drainage (USD) is a less invasive and effective alternativ...

Background: Historically open surgical drainage has been the treatment of choice for pyogenic liver abscess. The records of 54 patients with pyogenic liver abscess were reviewed to determine whether earlier diagnosis with current imaging tests and definitive treatment with antibiotics and aspiration drainage was an effective alternative to surgery. Methods: The clinical features, laborator...
