Slow Wound Healing In Women May Be Due To Estrogen

SOURCE: Medical News Today

DATE:  April 4, 2012

EXCERPT: "Estrogen causes wounds in women to heal slower than in men - who have lower levels of estrogen - says a new study published in the April 2012 issue of the FASEB Journal. In the report, scientists from the University of California, Berkeley, provide the first evidence that mild injury response in the eye is fundamentally different in males and females because of estrogen. This discovery provides new clues for successfully treating a wide range of inflammatory diseases such as dry eye disease, rheumatoid arthritis, lupus, multiple sclerosis, and scleroderma."   more

Occupational Sunlight Exposure And Kidney Cancer Risk In Men

SOURCE:  Medical News Today

DATE:  March 8, 2010

EXCERPT: "According to a new study, men employed in occupations with potential exposure to high levels of sunlight have a reduced risk of kidney cancer compared with men who were less likely to be exposed to sunlight at work. The study did not find an association between occupational sunlight exposure and kidney cancer risk in women."   more

SOURCE: Medical News Today

DATE:  March 31, 2009

EXCERPT: "In an international human genetic study, researchers at UT Southwestern Medical Center have identified a gene linked to the autoimmune disease lupus, and its location on the X chromosome might help explain why females are 10 times more susceptible to the disease than males."   more

Hormone Cream Smoothes Skin Not Damaged by Sun CME (with audio)

SOURCE: MedPage Today

DATE:  September 15, 2008

EXCERPT: "Estradiol cream stimulated collagen production which smoothed wrinkled skin in elderly women, but only in areas that had not been exposed to the sun, researchers here reported. ...  And the effect of estradiol appeared to be gender-specific. For example, although men did have a benefit, it was less than the response observed in women."    more

FDA Warns of Injection-Site Reactions with Naltrexone for Alcoholism

SOURCE: MedPageTODAY

DATE:  August 14, 2008

EXCERPT: "  Serious injection-site reactions, including abscesses that required surgical treatment up to debridement, have been reported in patients given naltrexone (Vivitrol) injections for alcoholism prevention.   ...  The FDA said data indicated that there is a variable depth of subcutaneous tissue dependent on the gender and weight of the patient. "Women may be physiologically at higher risk for injection-site reactions due to typically higher gluteal fat thickness," the FDA said. ..."   more
