MRSA pre-screening effective in reducing otolaryngic surgical infection rates
Pre-operative screening of patients for methicillin-resistant staphylococcus aureus (MRSA) may be an effective way to reduce infection rates following otolaryngic surgeries, according to new research published in the January 2009 issue of Otolaryngology – Head and Neck Surgery.
Replacing a total hip replacement
Each year thousands of patients undergo total hip replacement surgery in order to help alleviate pain associated with debilitating hip disease and other related hip problems. According to a new study published in the January 2009 issue of The Journal of Bone and Joint Surgery, while many successful, long-term results have been documented, limited information currently exists regarding why hip replacements fail in the United States population.
Toxicity mechanism identified for Parkinson's disease
Neurologists have observed for decades that Lewy bodies, clumps of aggregated proteins inside cells, appear in the brains of patients with Parkinson's disease and other neurodegenerative diseases. more
Molecular imaging enables earlier, individualized treatment of thyroid cancer
In a study to determine the diagnostic value of molecular imaging in nodal staging of patients with thyroid cancer, researchers were able for the first time to accurately distinguish between cancerous cells in regional lymph nodes and normal residual thyroid tissue directly after surgery. more
Dormant cancer cells rely on cellular self-cannibalization to survive
A single tumor-suppressing gene is a key to understanding, and perhaps killing, dormant ovarian cancer cells that persist after initial treatment only to reawaken years later, researchers at The University of Texas M. D. Anderson Cancer Center report in the December Journal of Clinical Investigation
Scientists identify new congenital neutropenia syndrome and causative gene mutation
A team of scientists has discovered a new syndrome associated with severe congenital neutropenia (SCN), a rare disorder in which children lack sufficient infection-fighting white cells, and identified the genetic cause of the syndrome: mutations in the gene Glucose-6-phosphatase, catalytic subunit 3 (G6PC3). The findings, which are published in the Jan. 1, 2009 issue of The New England Journal of Medicine, were made by an international team of scientists, composed of 14 researchers from the Medical School of Hannover in Germany and12 from other research institutions, including the National Center for Biotechnology Information at the National Library of Medicine, National Institutes of Health. more
Family history of prostate cancer does not affect some treatment outcomes
In a first of its kind study, a first-degree family history of prostate cancer has no impact on the treatment outcomes of prostate cancer patients treated with brachytherapy (also called seed implants), and patients with this type of family history have clinical and pathologic characteristics similar to men with no family history at all, according to a January 1 study in the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology. more
