Bacteria resistant to the antibiotic colistin are also commonly resistant to antimicrobial substances made by the human body, according to a study in mBio, the online open-access journal of the American Society for Microbiology. Cross-resistance to colistin and host antimicrobials LL-37 and lysozyme, which help defend the body against bacterial attack, could mean that patients with life-threatening multi-drug resistant infections are also saddled with a crippled immune response. Colistin is a last-line drug for treating several kinds of drug-resistant infections, but colistin resistance and the drug's newfound impacts on bacterial resistance to immune attack underscore the need for newer, better antibiotics. http://medicalxpress.com/news/2013-05-resistance-last-line-antibiotic-bacteria-resistant.html Diseases, Conditions, Syndromes Tue, 21 May 2013 00:00:01 EST news288291710 Antibiotics for acute rhinosinusitis (ARS) are prescribed frequently— especially for younger adult patients and in primary care settings—despite recent consensus guidelines that discourage antibiotic use in mild cases, according to a study in the May 2013 issue of Otolaryngology–Head and Neck Surgery. http://medicalxpress.com/news/2013-05-variations-antibiotic-acute-rhinosinusitis-states.html Surgery Thu, 09 May 2013 10:48:45 EST news287315304 Giving prescribers access to education and advice or imposing restrictions on use can curb overuse or inappropriate use of antibiotics in hospitals, according to a new Cochrane systematic review. This is important because unnecessary use of these life-saving drugs is a key source of antibiotic resistance in bacteria. http://medicalxpress.com/news/2013-04-excessive-antibiotics-hospitals.html Medications Mon, 29 Apr 2013 19:00:02 EST news286480695 A more rapid laboratory test for pregnant women to detect potentially deadly Group B strep (GBS) has been successful at identifying GBS colonization in six and a half hours, according to the results of a study from The University of Texas Health Science Center at Houston (UTHealth). http://medicalxpress.com/news/2013-03-rapid-group-strep-successful.html Obstetrics & gynaecology Fri, 08 Mar 2013 17:55:20 EST news281987709 An increasing number of bacteria is evolving antibiotic resistance. Much-feared representatives of this steadily growing group include Staphylococci strains. At this point, multi-resistant forms of the bacterium Staphylococcus aureus - the "hospital germ" known commonly by its acronym, MRSA - can only be treated with a select subset of antibiotics as many drugs have simply stopped working. This is precisely why the field of medicine is in desperate need of new treatment options. http://medicalxpress.com/news/2013-02-multi-resistant-germs.html Diseases, Conditions, Syndromes Wed, 13 Feb 2013 09:51:22 EST news279971456 A major European and global health issue is resistance to or inappropriate use of antibiotics. The European Centre for Disease Prevention and Control (ECDC) estimates that each year, antimicrobial resistance (AMR) results in 25 000 deaths and related costs of over EUR 1.5 billion in healthcare expenses and productivity losses. Over the last four years, there has been a significant increasing trend of combined resistance to multiple antibiotics in both Klebsiella pneumoniae and E. coli in more than one-third of the EU/EEA countries. In addition, in several Member States, between 25 % and up to more than 60 % of Klebsiella pneumoniae from bloodstream infections show combined resistance to multiple antibiotics. http://medicalxpress.com/news/2013-01-threat-antibiotic-resistance.html Diseases, Conditions, Syndromes Thu, 10 Jan 2013 06:15:02 EST news277020890 As a result of concerns about antibiotic resistance, doctors in the United States are increasingly prescribing newer, more costly and more powerful antibiotics to treat urinary tract infections, one of the most common illnesses in women. http://medicalxpress.com/news/2012-10-antibiotic-resistance-urinary-tract-infection.html Medications Thu, 11 Oct 2012 15:40:43 EST news269188834 Career paths can start to take shape in many unexpected ways.

Few studies have compared treatments against each other in terms of effectiveness and safety. Furthermore, concerns that the long-term use of antibiotics to treat acne might contribute to bacterial resistance increases the urgency to test treatment regimens and to develop more effective non-antibiotic therapies, according to a Seminar, published Online First in The Lancet. http://medicalxpress.com/news/2011-08-lack-widely-acne-treatments-limiting.html Medications Mon, 29 Aug 2011 18:30:01 EST news233847500 Total joint replacement surgeries can help relieve joint pain common in people with conditions like osteoarthritis. But sometimes, the debris from prosthetic joints leads to aseptic loosening, or disintegration of surrounding bones. In 2009, a Wayne State University researcher determined that the anti-inflammatory antibiotic erythromycin can prevent and treat such disintegration. There was one caveat, however: there are side effects associated with long-term usage of erythromycin. http://medicalxpress.com/news/2011-08-antibiotic-localized-treatment-bone.html Medical research Tue, 09 Aug 2011 08:33:15 EST news232097583
