Medscape Medical News    Share   Share on FacebookTwitterShare on LinkedinE-mail article
The US. Food and Drug Administration gave clinicians a much-needed new weapon against tough bacterial infections by approving ceftaroline fosamil (Teflaro; Forest Laboratories) for treating community-acquired bacterial pneumonia and acute bacterial skin and skin-structure infections, including the notorious methicillin-resistant Staphylococcus aureus. Ceftaroline, an injectable antibiotic, is a cephalosporin, which counter bacteria by interfering with their cell walls. More

Scientists have managed to produce a small-scale version of a human liver in the laboratory using stem cells. The success increases hope that new transplant livers could be manufactured, although experts say that this is still many years away. More

Researchers: Lungs can 'taste' dangerous bacteria
The Wall Street Journal    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The same taste buds we have on the tongue to detect bitterness also exist on lung muscle so that the airways can "taste" dangerous illness-causing bacteria, according to new research published that could lead to better treatments for respiratory conditions. When the taste receptors in the lungs detect these bugs that cause pneumonia and other serious infections, the muscle relaxes and the airways expand. More

Cancer antigen 125 (CA125) levels decline significantly after bilateral salpingo-oophorectomy (BSO), to the extent that normal reference levels might not apply to these women, researchers from The Netherlands report. The currently accepted upper limit of 35 U/mL for CA125 is based on values measured in healthy men and women with a median age of 35 years, the researchers note, but normal values vary during the normal menstrual cycle and differ between premenopausal and postmenopausal women.

Early data from the 1,000 Genomes Project, an international effort to build a detailed map of human genetic variation, is already offering new clues about human disease, including why some people are more severely affected by disease than others. Dr. Evan Eichler of the University of Washington in Seattle and colleagues used findings from the pilot phase of the project to identify subtle differences among people in areas of the genome where DNA sequences are often repeated many times.

Conventional yearly Pap test reduces cancer risk
after CIN treatment

Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
An annual conventional Pap test appears to be the best method for reducing cervical cancer deaths, and costs, in women who have been previously treated for high-grade cervical intraepithelial neoplasia. According to a modeling study, published in the November issue of Obstetrics & Gynecology, yearly conventional cytology surveillance reduced cervical cancers and cancer deaths in this population, compared with triennial cytology.
