This Study May Prevent Broken Bones

The best way to prevent a fracture is to stop bones from reaching the point where they are prone to breaking, but understanding the process of how bones form and mature has been challenging. Now researchers at the University of Houston department of health and human performance have created a process that grows real human bone in tissue culture, which can be used to investigate how bones form and grow. "We have manufactured a structure that has no synthetic components, " said Mark Clarke, associate professor and principal investigator. "It's all made by the two cell types bones start with inside the body. What you end up with is a piece of material that is identical to newly-formed, human, trabecular bone, including its mineral components, its histology and its growth factor content.

Acute Leukemia: First-In-Class Treatment

EUREKA project E! 3172 NKSTIM has produced a new potential drug to stimulate cancer patients' own 'natural killer' cells to attack and eliminate cancer cells; currently undergoing clinical testing in patients with leukaemia or myeloma. Existing knowledge of how transplanted bone marrow cells eradicate tumours gave the foundation for designing the new drug. Providing the remaining clinical trials are successful, the drug will offer the first real treatment option for older people with acute myeloid leukaemia, whose age precludes them from bone marrow transplantation. It also promises improved options for treating other types of cancer, such as multiple myeloma and lymphoma.

UAB Bone Center Director Wins Distinguished Service Award From Clinical Pathology Society

The director of the University of Alabama at Birmingham (UAB) Center for Metabolic Bone Disease has won the 2009 Ward Burdick Award for Distinguished Service to Clinical Pathology from the American Society for Clinical Pathology (ASCP). Jay M. McDonald, M.D., a professor in the UAB Department of Pathology, is a leader in reforming and maintaining national standards for clinical pathology training. McDonald helped author the current highest standards for laboratory testing of diabetes mellitus samples and has been an international leader in establishing clinical pathology as both a basic research and clinical discipline. McDonald is a senior scientist at UAB's Comprehensive Cancer Center, Center for AIDS Research, Center for Aging, Gene Therapy Center, Center for Health Promotion and BioMatrix Engineering and Regenerative Medicine Center.

Recurring Dislocations? New Shoulder Repair Technique Effective When Standard Procedures Are Not

The shoulder is the most commonly dislocated joint in the human body, occurring most often in young, athletic people. New research from the University of Michigan Health System shows patients who have recurrent shoulder dislocations may benefit from surgical reconstruction using cadaver bone and cartilage to essentially 'sculpt' a new shoulder. For some patients, standard stability-restoring procedures are ineffective. "We've been looking at defects of the humeral head, which is the ball part of the shoulder, and the effects of those [defects] on recurrent instability following surgical repair, " says Jon Sekiya, M.D., surgeon and associate professor in the Department of Orthopaedic Surgery.

What Is A Fracture? What Are Broken Bones?

A fracture, also referred to as a bone fracture, FRX, FX, F x or # is a medical condition where the continuity of the bone is broke. A significant percentage of bone fractures occur because of high force impact or stress; however, a fracture may also be the result of some medical conditions which weaken the bones, for example osteoporosis, some cancers or osteogeneris imperfecta. A fracture caused by a medical condition is known as a pathological fracture. The word break is commonly used by lay (non-professional) people. Among health care professionals, especially bone specialists, such as orthopedic surgeons, break is a much less common term when talking about bones.

University Of Florida Scientists Use Virus To Kill Cancer Cells While Leaving Normal Cells Intact

A virus that in nature infects only rabbits could become a cancer-fighting tool for humans. Myxoma virus kills cancerous blood-precursor cells in human bone marrow while sparing normal blood stem cells, a multidisciplinary team at the University of Florida College of Medicine has found. The findings are now online and will appear in an upcoming issue of the journal Leukemia. The discovery could help make more cancer patients eligible for bone marrow self-transplant therapy and reduce disease relapse rates after transplantation. "This is a new strategy to remove cancer cells before the transplant, " said virologist Grant McFadden, Ph.D., senior author of the paper and a member of the UF Genetics Institute.

Most Surveyed Clinicians Will Prescribe Amgen GlaxoSmithKline's Prolia As Either A Second Or Third Line Therapy For Osteoporosis

Decision Resources, one of the world's leading research and advisory firms for pharmaceutical and healthcare issues, finds that the majority of surveyed clinicians say they will use Amgen/GlaxoSmithKline's Prolia as either a second- or third-line therapy for osteoporosis if the drug receives regulatory approval for the indication. Prolia, which is expected to receive approval from the Food and Drug Administration in early 2010, will be prescribed in later lines of therapy as most surveyed clinicians indicate that they will likely continue using bisphosphonates as first-line treatments. Bisphosphonates, most notably alendronate (Merck's Fosamax, generics) and Sanofi-Aventis/Procter & Gamble's Actonel, currently dominate the osteoporosis and osteopenia drug markets.

Predictive Implications Of Bone Turnover Markers After Treatment In Hormone-Refractory Prostate Cancer Patients With Painful Osseous Metastases - Bone is a very common site of prostate cancer metastases, and in most patients the only site of disease progression. At the skeletal site of metastatic invasion, the bone metabolism is deregulated as a result of the presence of tumour cells in the bone microenvironment. Since emerging evidence suggests that biomarkers of bone turnover carry notable potential to become useful tools for monitoring patients with metastatic bone disease, we measured a panel of bone formation and bone resorption markers in a relatively homogenous group of patients with hormone-refractory prostatic carcinoma (HRPC) and bone only metastases, immediately before 186Rhenium-l, l-hydroxyethylidene diphosphonate (186Re-HEDP) therapy and strictly after 3 months.

DGIMED Receives FDA Clearance On IM Nail System

DGIMED ORTHO, Inc. announced that the company has received notification of clearance on its 510(k) submission for the Company's proprietary Drill and Intramedullary (IM) Nail system. "This timely notification keeps us on track as we now plan to initiate our market validation work to gain additional feedback on our system. This will significantly contribute to our continued development of the next generation DISTALOCK Drill and IM Nail system." said Phil Smith, the Company's President and CEO. "This is great news! " The Drill System uses an innovative approach to ensure the accurate placement of the distal locking screws used to stabilize the rod-like implants used for long bone fractures of the femur and tibia.

Good Stress Response Enhances Recovery From Knee Surgery, Stanford Study Shows

The right kind of stress response in the operating room could lead to quicker recovery for patients after knee surgery, according to a new study led by Stanford University School of Medicine researchers. The results could be used to develop methods for predicting how well patients will fare after they leave the hospital. The study, conducted with colleagues at Yale University and published Dec. 1 in the Journal of Bone and Joint Surgery, found that patients whose immune systems responded to the stress of surgery by mobilizing large numbers of pathogen-fighting cells and redistributing them to skin and other tissues recovered more quickly and completely than those patients whose immune system showed little or no reaction.
