RF- Insufficient Exposure to Sunlight and Global Mortality: Should We Advise Against or Recommend Sun Exposure?

Sunlight exposure assessment: can we accurately assess vitamin D exposure from sunlight questionnaires?

The purpose of this review is to summarize the peer-reviewed literature in relation to sunlight exposure assessment and the validity of using sunlight exposure questionnaires to quantify vitamin D status. There is greater variability in personal ultraviolet (UV) light exposure as the result of personal behavior than as the result of ambient UV light exposure. Although statistically significant,...

Sun exposure and mortality from melanoma.

BACKGROUND Melanoma incidence and survival are positively associated, both geographically and temporally. Solar elastosis, a histologic indicator of cutaneous sun damage, has also been positively associated with melanoma survival. Although these observations raise the possibility that sun exposure increases melanoma survival, they could be explained by an association between incidence and early...

Re: Sun exposure and mortality from melanoma.

The relationship between sun exposure and melanoma mortality and risk of lymphoma was explored in two recent articles and a related editorial ( 1 – 3 ) .

( 2 ) demonstrated, within the limits of a retrospective study, that patients with melanoma have a better prognos...

Should we recommend PEC and when?

Percutaneous endoscopic colostomy (PEC) was first described in 1986, by Jeffrey Ponski [1], who had invented percutaneous endoscopic gastrostomy a few years before that [2]. Performed by 2 operators, PEC consists of placing a tube in the colon during colonoscopy in order to provide antegrade colonic enemas (ACE) in severe constipation or fecal incontinence [3,4]. The PEC tube can also be used a...
