A 70 year old lady of recurrent ischaemic stroke on a chronic urinary catheter presented with purple discoloration of her catheter bag. Clinically, she was febrile. The urinary catheter drainage bag (Panel A) was purple stained. Her urine pH was alkaline at 7.5 with leucocytes present. The urine culture grew Klebsiella pneumoniae. She was treated with ampicillin/sulbactam which led to the resol...

Society's use of plastic is increasing, while the ability to properly manage waste decreasing. In response, improved management systems and adoption reusable products made from sustainable materials are needed. Municipal governments in United States beginning institute policies reducing unlimited free access such as bags, straws, Styrofoam. However, some state Great Lakes region, elsewhere, hav...

BACKGROUND Sealed irrigation of the capsular bag after removal of the cataractous lens isolates the interior of the capsular bag from the anterior segment, permitting isolated targeting of lens epithelial cells (LECs) in vivo using pharmacologic agents while minimizing the risk of damage to other intraocular structures. OBJECTIVES To assess the ability to deliver a nonspecific, extremely toxi...

Endotracheal intubation and extubation in intensive care unit (ICU) patients are difficult. Extubation will be more worrisome if patient has difficult intubation, sleep apnea, surgical procedure involving airway or surrounding structures. In such extubation airway exchange catheters (AEC) are used, as they are simple to use and able to provide oxygen to the patient. Rarely AEC use can cause pot...

the present study was conducted to investigate the possibility of using a modified in vitro gas production technique in place of the nylon bag method to estimate protein degradability of alfalfa hay in ruminants. in the in situ experiment dacron bags were filled with 3 g alfalfa hay. this was incubated in the rumen of three ruminally cannulated ghezel rams for the periods of 0, 2, 4, 8, 12, 16,...

Regulation of goods associated with negative environmental externalities may decrease consumption the targeted product, but be ineffective at reducing externality itself if close substitutes are left unregulated. We find evidence that plastic bag bans, most common disposable regulation in US, led retailers to circumvent by providing free thicker bags which not covered ban. In contrast, a change...
