Are Organic Foods Safer or Healthier Than Conventional Alternatives? A Systematic Review

Posted by on in Skin Matters

alert_12_iconThe health benefits of organic foods are unclear. To review evidence comparing the health effects of organic and conventional foods. MEDLINE (January 1966 to May 2011), EMBASE, CAB Direct, Agricola, TOXNET, Cochrane Library (January 1966 to May 2009), and bibliographies of retrieved articles. English-language reports of comparisons of organically and conventionally grown food or of populations consuming these foods. 17 studies in humans and 223 studies of nutrient and contaminant levels in foods met inclusion criteria.

Immunosuppressive effects of fish oil and flaxseed oil

Posted by on in Skin Matters

Alert_11_iconThe omega-6 fatty acids are the predominant polyunsaturated fats. The omega-6 and omega-3 fatty acids are metabolically distinct and have opposing physiologic functions. Animal and human studies support the hypothesis that omega-3 PUFA suppress cell mediated immune responses. The increased omega-6/omega-3 ratio in Western diets most likely contributes to an increased incidence of cardiovascular disease and inflammatory disorders.

A Comprehensive Review of the Adverse Effects of Systemic Corticosteroids

Posted by on in Skin Matters

Corticosteroids are commonly prescribed by practitioners in many medical specialties for the treatment of chronic inflammatory conditions. The use of corticosteroids in the treatment of chronic rhinosinusitis is well described and based on their anti-inflammatory effects. The duration of corticosteroid therapy in these conditions is often less than 1 month, in contrast to the treatment of chronic respiratory diseases (ie, asthma, chronic obstructive pulmonary disease) or autoimmune disorders (ie, rheumatoid arthritis, systemic lupus erythematosus, Crohn disease, and ulcerative colitis), which can last for years.

Immunosuppressive activity on the murine immune responses of glycyrol from Glycyrrhiza uralensis via inhibition of calcineurin activity

Posted by on in Skin Matters

This paper is to search for an effective immunosuppressant from Glycyrrhiza uralensis (Licorice, Gan Cao). Our results show the immunosuppressive activity of glycyrol and this activity should be due to its inhibitory effect on CN activity, thereby suppressing IL-2 production and regulating T lymphocytes. Thus, glycyrol could be a candidate for development as a novel immunomodulatory drug.

Biologic Therapy and Risk of Infection

Posted by on in Skin Matters

Biologic compounds are being used more frequently to treat a multitude of systemic inflammatory conditions. These novel compounds are composed of antibodies or other peptides that act through one of three mechanisms: inhibiting inflammatory cytokine signaling (typically tumor necrosis factor or TNF), inhibiting T-cell activation, or depleting B-cells. The increase in use and ever expanding list of new immune modulating therapies make knowledge of the infectious complications associated with immune modulation even more important. Of particular concern is the risk for developing atypical and opportunistic infections including tuberculosis, herpes zoster, Legionella pneumophila, and Listeria monocytogenes.

Consequences of systemic absorption of topical glucocorticoids and Evaluation of the pituitary-adrenal axis function in patients on topical steroid therapy

Posted by on in Skin Matters

Alert4_iconIn this Volume 65, Issue 1 of the JAAD, Kerner et al report blunted adrenal responses after the use of topical corticosteroids. While it is reassuring that laboratory values remained within the normal range in this particular study, the blunted responses serve as a reminder that systemic absorption of topically applied corticosteroids can have systemic implications.

Resveratrol and curcumin suppress immune response through CD28/CTLA-4 and CD80 co-stimulatory pathway

Posted by on in Skin Matters

The role of resveratrol (can be extracted from grape, veratrum album which commonly known as the False Helleborine, also known as White Hellebore, European White Hellebore, White Veratrum) and curcumin (extracted from Turmeric, also known as yellow ginger) is well documented in cancer, inflammation, diabetes and various other diseases. However, their immuinnosuppressive action on T cells, B cells and macrophages is not well documented.

Multi-organ damage induced by anabolic steroid supplements: a case report and literature review

Posted by on in Skin Matters

alert2_iconThe use of anabolic supplements and other related drugs for bodybuilding and enhancing athletic performance is nowadays widespread and acutely pervasive all around the world. This alarming increase in the use of anabolic and amino acid supplements has been linked to a diverse array of pathologies. As previously reported, the abuse of androgenic steroids is not without severe physiological, psychiatric and physical costs.
