Periodontists routinely grow bone in the mouth to guarantee a stable environment for teeth and tooth implants. But whether it's better to build up bone before placing the implant, or to simply place the implant and allow bone to grow around it, has been a subject of considerable medical debate. http://medicalxpress.com/news/2012-05-two-step-tooth-implantation-built-up-bone.html Dentistry Tue, 22 May 2012 12:48:44 EST news256909708 Hip replacement is one of the most frequent operations carried out in Germany. Each year, doctors implant some 200,000 artificial hip joints. Often the artificial hips need to be replaced just ten years later. In the future, a new implant currently being developed using high technology materials could help prevent premature revision surgeries. http://medicalxpress.com/news/2012-05-hip-implant-long-term.html Other Fri, 04 May 2012 14:00:01 EST news255356920 Retina Implant AG, the developer of subretinal implants for patients blinded by retinitis pigmentosa (RP), announced that the first UK patients participating in the Company's multi-centre trial have been successfully implanted. The UK trial is set to include 12 patients in total and is being led in London by Mr. Tim Jackson, a consultant retinal surgeon at King's College Hospital and Senior Clinical Lecturer at King's College London, and in Oxford by Professor Robert MacLaren, professor of Ophthalmology at the University of Oxford and a consultant retinal surgeon at the Oxford Eye Hospital. http://medicalxpress.com/news/2012-05-patients-uk-retina-implant.html Medical research Thu, 03 May 2012 16:16:17 EST news255280566 (HealthDay) -- Hemiarthroplasty with the cemented Exeter implant provides pain relief comparable to hemiarthroplasty with the uncemented Alloclassic implant in elderly patients with a displaced femoral neck fracture, according to a study published in the April 4 issue of The Journal of Bone & Joint Surgery. http://medicalxpress.com/news/2012-04-hip-outcomes-similar-withwithout-cement.html Surgery Tue, 24 Apr 2012 14:30:02 EST news254490896 (Medical Xpress) -- Research to restore sight to the clinically blind has reached a critical stage, with testing underway of the prototype microchips that will power the bionic eye. http://medicalxpress.com/news/2012-04-microchip-success-bionic-eye.html Ophthalmology Tue, 03 Apr 2012 09:00:01 EST news252661058 The UK government's health regulator has advised new checks for patients who have undergone large head metal-on-metal hip replacements, following a major investigation by Newcastle University engineers. http://medicalxpress.com/news/2012-03-lifelong-metal-hip-implant-patients.html Other Thu, 01 Mar 2012 05:33:12 EST news249802376 (HealthDay) -- Testing patients for metal hypersensitivity before they receive joint or bone implants helps identify those at increased risk for complications due to metal hypersensitivity, a new study shows. http://medicalxpress.com/news/2012-02-skin-metal-sensitivity-joint.html Other Fri, 24 Feb 2012 13:50:01 EST news249308701 (HealthDay) -- Hormonal contraceptives appear to thwart pregnancy just as well in overweight and obese women as those of normal weight despite markedly lower pregnancy-prevention hormone levels among heavier females, a group of reproductive experts said. http://medicalxpress.com/news/2012-02-contraceptives-obese-women-hormone.html Obstetrics & gynaecology Fri, 24 Feb 2012 11:10:01 EST news249302807 A French judge on Friday charged the founder of the breast implant company at the heart of a global health scare with "involuntary injuries", his lawyer said. http://medicalxpress.com/news/2012-01-french-boss-breast-implant-firm.html Other Fri, 27 Jan 2012 04:50:03 EST news246860736 Researchers funded by the National Institutes of Health have developed a flexible brain implant that could one day be used to treat epileptic seizures.

Medical engineers at Technische Universitaet Muenchen have developed an electronic sensor chip that can determine the oxygen content in a patient's tissue fluid. This data can then be wirelessly transmitted to the patient's doctor to support the choice of therapy. A drop in oxygen content in tissue surrounding a tumor indicates that the tumor might be growing faster and becoming aggressive. http://medicalxpress.com/news/2011-08-sensor-chip-tumors.html Medical research Fri, 26 Aug 2011 10:51:49 EST news233574698 Patients with uveitis, the fifth leading cause of vision loss in the United States, treated with either systemic anti-inflammatory medicine or with a time-release implant surgically placed inside the eye experienced a similar degree of visual improvement over two years, according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania, the Mount Sinai School of Medicine, Johns Hopkins University and the University of Wisconsin.

The treatment, called InterStim Therapy is a minimally invasive procedure which uses electrical impulses to stimulate the sacral nerve and improve muscle function. It is one of the only effective long-term treatments for bowel incontinence available to patients and Northwestern Memorial Hospital is one of the first medical centers in the country to offer the procedure. http://medicalxpress.com/news/2011-07-therapy-millions-people-bowel-incontinence.html Diseases, Conditions, Syndromes Mon, 18 Jul 2011 14:41:58 EST news230218877
