BACKGROUND |
The use of a metal radial head prosthesis to help stabilize an elbow with traumatic instability is appealing because internal fixation of multifragment, displaced fractures of the radial head is susceptible to either early or late failure. The newer modular prostheses are easier to size and implant, but their effective... |
METHODS |
Twenty-seven patients in whom a radial head replacement with a modular metal spacer prosthesis had been performed to treat traumatic elbow instability were evaluated with use of the Mayo Elbow Performance Index (MEPI), the American Shoulder and Elbow Surgeons Elbow Evaluation Instrument (ASES), and the Disabilities of ... |
RESULTS |
Seven patients underwent one or more subsequent operations to treat residual instability, heterotopic ossification and elbow contracture, ulnar neuropathy, or a misplaced screw. In two of these patients, the prosthesis was removed as part of an elbow contracture release or to treat infection. At an average of forty mon... |
CONCLUSIONS |
An intentionally loosely placed modular metal radial head prosthesis can help to restore stability in conjunction with repair of other fractures and reattachment of the lateral collateral ligament to the epicondyle in the setting of traumatic elbow instability with a comminuted fracture of the radial head. While a pros... |
The death toll from a government run mass sterilisation programme in the Indian state of Chhattisgarh reached 13 on 12 November, with a further 14 women described as “seriously ill.” |
The deaths triggered outrage across central India, where protesters took to the streets, smashed cars, and asked for the resignation of Raman Singh, the chief minister of Chhattisgarh.1 |
The sterilisations took place on 8 November in Bilaspur. A 59 year old doctor, R K Gupta, performed laparoscopic sterilisations on 83 women at a mass sterilisation camp held under a government …Lohmannella (Acari, Halacaridae) from a cold-water coral reef off Norway, description of two new and a list of North Atlantic ... |

BACKGROUND |
Berries are known to have many kinds of biological activities. We focused on their antiviral effect, which has not yet been well evaluated. |
RESULTS |
We compared the anti-influenza viral effects of berries belonging to the genus Vaccinium - 35 species of blueberry (Vaccinium cyanococcus), the Natsuhaze (Vaccinium oldhamii), bilberry (Vaccinium myrtillus) and cranberry (Vaccinium oxycoccos)- with those belonging to the genus Ribes, i.e. blackcurrant (Ribes nigrum). O... |
CONCLUSIONS |
Antiviral effects were found to differ markedly between berry species. Rabbiteye varieties tended to have higher antiviral effects than Northern, Southern and Half Highbush blueberry varieties. We also found that Natsuhaze, which has recently been harvested in Japan as a potential functional food, had an antiviral effe... |
