We determined the association between vitamin D status as 25hydroxyvitamin D [25(OH)D] and disease activity in a cohort of 201 Crohn's Disease (CD) patients in Saskatoon, Canada over three years. The association between high-sensitivity C-reactive protein (hs-CRP) and 25(OH)D and several disease predictors were evaluated by the generalized estimating equation (GEE) over three time-point measure...

Background: Febrile seizures are the most common convulsive disorder in children. There is growing evidence that vitamin D can affect gene expression and modulate various cell metabolisms. Also vitamin D may have a role in the etiology of febrile seizures. We aimed to explore vitamin D status in children with febrile seizure. Materials and Methods: This cross-sectional study was conducted on 40...

The majority of the vitamin D in our body is produced by cutaneous synthesis in response to sunlight. As more and more people live in cities and spend the bulk of their time indoors, it can be difficult to get sufficient sun exposure for adequate cutaneous production of vitamin D. Therefore, vitamin D insufficiency has become a very common health problem worldwide. The Korea National Health and...

We read with concern the article by Tangpricha et al (1) on tanning and vitamin D status in a recent issue of the Journal. They concluded, on the basis of their study, that “tanning beds may also provide some medical benefit.” Our concern is based on several factors. First, Tangpricha et al recruited a convenience sample via an online bulletin board and newspaper advertisement. Hence, their stu...
