Abstract
Studies point out that trace elements take vital roles in immunological and inflammatory reactions, such as psoriasis, while the conclusions are controversial. The purpose of this study was to analyze the existing literatures and explore the relationship between the risk of psoriasis and four trace elements zinc (Zn), copper (Cu), iron (Fe), and selenium (Se). We identified 42 studies through the databases PubMed, Embase, Cochrane Library, Google Scholar, and Web of knowledge. After the meta-analysis, the serum zinc, iron, and selenium levels showed no remarkable difference between psoriasis and controls. The people with psoriasis showed a higher level of zinc in lesion tissue (standard mean difference (SMD) = 14.43; 95% confidence interval (CI), 7.89-20.97; P < 0.0001), and a higher level of serum copper than controls (SMD = 18.23; 95% CI, 5.06-31.40; P = 0.007). Our findings indicated that the trace element of copper and zinc levels are in a homeostatic imbalance in psoriasis patients when compared with controls, which raise the question whether this imbalance can be taken as the therapy target for psoriasis.

Abstract
In this review article we discuss current knowledge about iron in the skin and the cutaneous wound healing process. Iron plays a key role in both oxidative stress and photo-induced skin damage. The main causes of oxidative stress in the skin include reactive oxygen species (ROS) generated in the skin by ultraviolet (UVA) 320-400 nm portion of the UVA spectrum and biologically available iron. We also discuss the relationships between iron deficiency, anemia and cutaneous wound healing. Studies looking at this fall into two distinct groups. Early studies investigated the effect of anemia on wound healing using a variety of experimental methodology to establish anemia or iron deficiency and focused on wound-strength rather than effect on macroscopic healing or re-epithelialization. More recent animal studies have investigated novel treatments aimed at correcting the effects of systemic iron deficiency and localized iron overload. Iron overload is associated with local cutaneous iron deposition, which has numerous deleterious effects in chronic venous disease and hereditary hemochromatosis. Iron plays a key role in chronic ulceration and conditions such as rheumatoid arthritis (RA) and Lupus Erythematosus are associated with both anemia of chronic disease and dysregulation of local cutaneous iron hemostasis. Iron is a potential therapeutic target in the skin by application of topical iron chelators and novel pharmacological agents, and in delayed cutaneous wound healing by treatment of iron deficiency or underlying systemic inflammation.

Abstract
There is growing scientific evidence that the health, well-being and the attractiveness of the skin are strongly influenced by nutrition. Consumers recognize this and have supported the creation of a global cosmeceuticals market estimated in 2010 at $27.2 billion. Early in 2011, the US Department of Health and Human Services and Department of Agriculture issued the Dietary Guidelines for Americans, 2010. Twelve vitamins and nine minerals were recognized as essential. The minerals include calcium, copper, iron, magnesium, phosphorus, selenium, zinc, potassium and sodium. Although the topical benefits of several minerals such as zinc, magnesium and iron are recognized and, in some cases, approved by the FDA, the topical benefits of the others to the skin are largely unexplored and unexploited. This review attempts to summarize what has been published in the literature on the interactions of the eight of the nine essential elements with the skin.

Abstract
The content of chemical elements in rainwater is a suitable indirect indicator of its presence in airborne dust, sometimes referred to as rain fallout. Rainwater is considered a suitable monitor for environmental or natural pollution. The yearly content of chemical elements in rainwater may be considered as a good indicator for determining the influence of these environmental factors on the human body. We decided to investigate the relationship between chemical elements in rainwater and the frequency of hospitalizations for arterial hypertension, chronic obstructive pulmonary disease, and psoriasis. There is a mild correlation between zinc and cadmium and cases of arterial hypertension. For obstructive pulmonary disease, there is a strong correlation with the content of potassium, calcium, iron, manganese, lead and nickel, and with chloride, sulfide, total nitrogen, and nitrites. There is also a mild correlation with magnesium, zinc, copper, cadmium and chromium, and with ammonium nitrogen. In cases of hospitalization for psoriasis, a correlation was revealed with such elements as potassium, ammonium nitrogen, and phosphorus.

Abstract
Epidermal desquamation, a continuous but insensible bodily activity, is largely ignored unless the rate or amount of scale production becomes abnormal. It is the last topic to be considered in any serious discussion of epidermal growth and differentiation, but is becoming an increasingly fertile ground for investigation. This review summarizes: (a) methods for measuring desquamation; (b) variables that affect normal desquamation; (c) mechanisms of desquamation; (d) the role of desquamation in nutritional homeostasis; and (e) the role of desquamation as a first line of defense. Consideration is given to whether desquamation might be harnessed to eliminate or remediate toxins that have accumulated in the body.

Abstract
Until recently, the determination of metallic elements concentrations in normal skin, in vivo, was rare due to the lack of non-invasive techniques. Microdialysis has the advantage of being slightly invasive when applied to the collection in vivo of endogenous or exogenous substances from the skin. Iron is an active element in different cutaneous disorders. The aim of this work was to assess iron by atomic absorption spectrometry (AAS) after the collection of samples by microdialysis from human dermis. A first essential step, before determining the in vivo iron concentration in human dermis, was to establish an experimental protocol applicable to ex vivo as well as in vivo conditions. For this reason, this work deals only with the assessment of iron in ex vivo human dermis. A skin microdialysis technique and a calibration method, the No Net Flux, were used to quantify basal iron concentrations in human dermis and the same method was also used to determine in vitro and ex vivo iron recoveries. No differences were detected between in vitro and ex vivo recoveries. Ex vivo basal iron dermis concentrations ranged from 3.6 to 7.7 microg/l. This study shows that non-invasive microdialysis is an efficient method for sampling iron from human skin. A sensitive and accurate AAS technique was able to assess low iron concentrations in human dermis. The strategy adopted for this work was efficient and appropriate for the determination of iron in human skin and experiments will be carried out in vivo.

Abstract
The cellular part of the skin, the epidermis, is a very thin structure, approximately 120 microns thick, a fact which has hindered the exploration of the physiology of the epidermis in normal and pathological conditions. An additional complication is the fact that the epidermis contains layers of cells at different stages of differentiation. Therefore, conventional physiological capillary probes cannot, with any satisfactory precision, be located within a specified cell of a specified layer of the skin in vivo. Hence, alternative ways for the exploration of skin physiology have been sought for. In the past, analysis of the elemental content of skin was done was done as bulk measurements, and surprisingly wide ranges of elemental content were recorded. The width of these ranges was most certainly due to the sampling methods used rather than the sensitivity of the chosen method of analysis. Also, these older measurements did not discriminate between the different strata, and therefore the information provided little if any substance for a functional analysis of processes involved in normal and pathological differentiation of the epidermis. Particle probes, however, have been able to overcome such methodological problems. Over a period of 15 years we have studied normal human skin, normal-looking, paralesional skin from psoriatics, and skin from persons suffering from atopic dermatitis using PIXE analysis. In recent years, trace elements have been shown to work as secondary messengers or regulatory substances. As an example, calcium (Ca2+) has proven to be a very important signalling substance in a great variety of cellular systems. Studies with the transmission electron microscope (TEM) as well as histochemical methods have allowed an understanding of the role of Ca2+ in the differentiation process of the epidermis. Ca2+ has also been shown to play an important role in apoptosis (programmed cell death), which is currently a hot subject for the obvious reason that the final differentiation step between the stratum granulosum level and the stratum corneum represents a particular aspect of programmed cell death. The importance of the balance between calcium and zinc in apoptosis has been clearly demonstrated in a number of cellular systems, but we have still to clarify the validity of topical treatment with Zn ointments in different skin conditions. Substantial iron (Fe) losses via psoriatic lesions were demonstrated more than two decades ago, and these data were given new meaning when we found that a more discrete loss occurs in clinically normal-looking psoriatic skin. Obviously, such findings stress the importance of understanding the relation between the elemental content and normal and abnormal physiology. The ultimate goal of particle probe studies is to provide an understanding of the formation of a mature stratum corneum with a functional barrier reflected in physiological/biochemical mechanisms behind the properties of changed skin in patients afflicted with skin disorders of genetic or constitutional origin. This paper aims to give an overview of the state of the art in skin physiology made possible through the use of particle probes.

Abstract
BACKGROUND There is no objective laboratory technique to measure and to monitor disease activity in psoriasis. OBJECTIVE We assessed the effectiveness of using phosphorus 31 (31P) magnetic resonance spectroscopy (MRS) to noninvasively monitor metabolism in psoriasis and to compare these spectroscopic data with chromatographic analysis. METHODS Fourteen persons were enrolled in the study. 31P magnetic resonance spectra were obtained from skin of persons without skin disease, uninvolved psoriatic skin, nonpsoriatic erythroderma, and from skin of patients with psoriasis. In three patients with psoriasis 31P magnetic resonance spectra were repeated after treatment with methotrexate, UVB, etretinate, and topical steroids. Finally, shave biopsy specimens were obtained from two patients with psoriasis and submitted for chromatographic evaluation. RESULTS In patients with severe psoriasis, in comparison with the control group, elevations in phosphomonoester concentrations and in the phosphomonoester/phosphodiester ratio were observed. These appear to be useful markers to monitor treatment response in patients with psoriasis. Finally, 31P MRS data in conjunction with chromatographic analysis indicated a defect in phosphometabolism in psoriatic skin. However, it is unclear whether this defect is a cause or an epiphenomenon of the disease. CONCLUSION 31P MRS appears to be a sensitive, noninvasive technique to monitor disease activity in psoriasis. Further studies to characterize the defect in phosphometabolism in psoriatic skin are warranted.
