Robotic surgical technology with its three-dimensional, high-definition view gives surgeons the sensation of touch, even as they operate from a remote console. A new study describes the phenomenon, called intersensory integration, and reports that surgical outcomes for prostate cancer surgery using minimally invasive robotic technology compare favorably with traditional invasive surgery.

Contralateral prophylactic mastectomy, a preventive procedure to remove the unaffected breast in patients with disease in one breast, may only offer a survival benefit to breast cancer patients age 50 and younger, who have early-stage disease and are estrogen receptor negative, according to researchers.

A research team that conducted the gene therapy trial for an inherited blindness reports that a study in animals has shown that a second injection of genes into the opposite, previously untreated eye is safe and effective, with no signs of interference from unwanted immune reactions following the earlier injection. These new findings suggest that patients who benefit from gene therapy in one eye may experience similar benefits from treatment in the other eye.

Scientists recently assessed the light emitted by a home-use intense-pulsed light (IPL) hair reduction system and confirmed that it is safe. This confirmation is important, as IPL devices must meet the necessary safety guidelines, to ensure users are protected in the case of accidental exposure to the human eye.

An eight-year prospective study of more than 30,000 postmenopausal Swedish women found that those who were using or had used HRT had significantly higher rates of cataract removal, compared with women who had never used HRT. Alcohol consumption seemed to increase HRT's harmful effect.

Senior eye doctors are warning people to keep liquid capsules for fabric detergents out of the reach of children after a wave of eye injuries in young children at their hospital.

In an eye-opening editorial, a leading expert urges the medical community to use ultrasound instead of computed tomography as the first-line imaging test for better diagnosis capability in the evaluation of acute female pelvic and lower abdominal conditions.

Researchers are now a step closer to deciphering a leading cause of blindness in the United States -- glaucoma. They found that the first sign of injury in glaucoma actually occurs in the brain. The findings show that glaucoma is very much like other neurodegenerative central nervous system diseases.

Researchers have determined that regular use of aspirin, acetaminophen and non-steroidal anti-inflammatory drugs increases the risk of hearing loss in men, particularly in younger men, below age 60.

Researchers have developed a new assessment tool to measure the severity of symptoms that can complicate stem cell transplantation. The tool assesses symptoms resulting from chronic graft-vs.-host disease (cGVHD).

Researchers have discovered a new method for predicting -- with up to 99 percent accuracy -- the fate of stem cells. Using advanced computer vision technology to detect subtle cell movements that are impossible to discern with the human eye, scientists can successfully forecast how a stem cell will split and what key characteristics the daughter cells will exhibit.

Smoking is already a known risk factor for age-related macular degeneration, cataract and thyroid eye disease. Now, the first study to specifically examine the impact of smoking on uveitis-inflammation of the eye's middle layer of tissue-indicates that tobacco smoke likely plays a role in this serious eye disease, as well. In the United States about 10 percent of blindness is caused by uveitis.

Nanoparticles are atmospheric materials so small that they can't be seen with the naked eye, but they can very visibly affect both weather patterns and human health all over the world -- and not in a good way, according to a new study.

One year post-surgery, patients who underwent Descemet's stripping automated endothelial keratoplasty (DSAEK) experienced greater cell loss overall compared to those who underwent penetrating keratoplasty (PKP), according to a new analysis of data. However, the study showed that cell loss in DSAEK patients plateaued more quickly than in those who underwent PKP.

Scientists have discovered that TKS4, a protein implicated in cancer metastasis, also plays a significant role in Frank-Ter Haar syndrome, a rare fatal disorder.

Scientists in Massachusetts are reporting new evidence that certain high blood pressure drugs may be useful in preventing and treating diabetic retinopathy, the leading cause of vision loss in people with diabetes. The study, the largest to date on proteins in the retina, could lead to new ways to prevent or treat the sight-threatening disease, they say.

A comprehensive drug development strategy that starts with extensive screening of potential targeting peptides to identify prototype small-molecule drugs has produced two that target the EGFR and VEGFR pathways in novel ways.

Scientists have successfully used mouse embryonic stem cells to replace diseased retinal cells and restore sight in a mouse model of retinitis pigmentosa. This strategy could potentially become a new treatment for retinitis pigmentosa, a leading cause of blindness that affects approximately one in 3,000 to 4,000 people, or 1.5 million people worldwide.

A completely novel approach to analyzing time-lapse images of live stem cell behaviors has yielded a tool for successfully predicting outcomes of stem and progenitor cells. It will allow scientists to search for mechanisms that control stem cell specialization, the main obstacle in advancing the use of stem cell therapy for treatment of disease.

Schizophrenia and bipolar disorder affect 10s of millions of individuals around the world. These disorders have a typical onset in the early 20s and in most cases have a chronic or recurring course. Neither disorder has an objective biological marker than can be used to make diagnoses or to guide treatment.
