Link between skin cancer, vitamin D

Researchers at Henry Ford and Wayne State University have explained a link between Vitamin D levels and basal cell carcinoma, a discovery which could lead scientists to better understand the development of the most common form of skin cancer.

In a small study, boffins found elevated levels of Vitamin D enzymes and proteins in cancerous tissue taken from 10 patients compared to normal skin tissue taken from them.

Previous studies have linked Vitamin D deficiency with certain cancers but this is believed to be the first time researchers looked at Vitamin D and basal cell carcinoma.

“This finding may help us in future research to determine whether vitamin D plays a causative or reactive role in the development and progression of skin cancer,” says Iltefat Hamzavi, MD, senior staff physician in Henry Ford’s Department of Dermatology and the study’s lead author.

The study will be presented at the Photomedicine Society’s annual meeting in Miami, one day before the American Academy of Dermatology’s annual meeting.

Basal cell carcinoma is the most common form of skin cancer. This cancer forms in the basal cells of the deepest layer of the skin.

Stressed people likely to grind teeth at night

Stress not only hurts your brain, but also has a bad effect on teeth, claims a new study.
Boffins writing in BioMed Central’s open access journal Head & Face Medicine studied the causes of ‘sleep bruxism’, gnashing teeth during the night, finding that it was especially common in those who try to cope with stress by escaping from difficult situations.

Maria Giraki, from Heinrich-Heine-University, Düsseldorf, Germany, worked with a team of researchers to study the condition in 69 people, of whom 48 were ‘bruxers’.  

She said, “Bruxing can lead to abrasive tooth wear, looseness and sensitivity of teeth, and growth and pain in the muscles responsible for chewing.

Its causes are still relatively unknown, but stress has been implicated. Tooth grinding was measured by thin plates that were placed in trial participants mouths’ overnight, while stress and coping techniques were assessed by three questionnaires.

HIV/Aids is the leading cause of death in women

A UN programme on HIV/Aids has warned that HIV is fast becoming the leading cause of death and disease among women of reproductive age worldwide.

UNAids launched a five-year action plan at the start a 10-day conference in New York, addressing the gender issues which put women at risk.

And one of the key issues it said is that 70 percent of women worldwide have been forced to have unprotected sex.

UNAids says such violence against women should not be tolerated.

“By robbing them of their dignity, we are losing the opportunity to tap half the potential of mankind to achieve the Millennium Development Goals,” the BBC quoted Executive Director Michel Sidibe as saying.

“Women and girls are not victims, they are the driving force that brings about social transformation,” he stated.
