In cases where equipment is being placed in a container or bin and picked back up, nurses and doctors are required to wash their hands or use alcohol sanitizer before going back to the container to use the same equipment.Independent studies by Ignaz Semmelweis in 1846 in Vienna and Oliver Wendell Holmes, Sr. in 1843 in Boston established a link between the hands of health care workers and the spread of hospital-acquired disease. The U.S. Centers for Disease Control and Prevention (CDC) state that "It is well documented that the most important measure for preventing the spread of pathogens is effective handwashing". In the developed world, hand washing is mandatory in most health care settings and required by many different regulators.In the United States, OSHA standards require that employers must provide readily accessible hand washing facilities, and must ensure that employees wash hands and any other skin with soap and water or flush mucous membranes with water as soon as feasible after contact with blood or other potentially infectious materials (OPIM).In the UK healthcare professionals have adopted the Ayliffe Technique, based on the 6 step method developed by Graham Ayliffe, JR Babb and AH Quoraishi. Drying is an essential part of the hand hygiene process. In November 2008, a non-peer-reviewed study was presented to the European Tissue Symposium by the University of Westminster, London, comparing the bacteria levels present after the use of paper towels, warm air hand dryers, and modern jet-air hand dryers.
Like only few other known tetracycline derivatives, demeclocycline causes nephrogenic diabetes insipidus. Furthermore demeclocycline might have psychotropic side effects similar to lithium.Tetracyclines bind to cations, such as calcium, iron (when given orally), and magnesium, rendering them insoluble and inadsorbable for the gastrointestinal tract. Demeclocycline should not be taken with food (particularly milk and other dairy products) or antacids. Mechanism of action
As with related tetracycline antibiotics, demeclocycline acts by binding to the 30S ribosomal subunit to inhibit binding of aminoacyl tRNA which impairs protein synthesis by bacteria. It is bacteriostatic (it impairs bacterial growth, but does not kill bacteria directly).Demeclocycline inhibits the renal action of antidiuretic hormone by interfering with the intracellular second messenger cascade (specifically, inhibiting adenylyl cyclase activation) after the hormone binds to vasopressin V2 receptors in the kidney. Exactly how demeclocycline does this has yet to be elucidated, however. Brand names
Brand names include Declomycin, Declostatin, Ledermycin, Bioterciclin, Deganol, Deteclo, Detravis, Meciclin, Mexocine, and Clortetrin. == References ==
