background: staphylococcus aureus, the major virulence factor of hospital and community acquired infections, secretes numerous exotoxins (super antigens), which may affect immunological and inflammatory status in psoriatic skin lesion. objectives: this study is designed to compare the s. aureus super antigens level in sera of psoriatic patients with normal cases (nevus). patients and methods: a...

background: as the early and accurate diagnosis of all diseases, including skin disorders directly influences the duration of treatment and its costs, which may be a significant burden, it is very important for physicians to be familiar with all types of diseases, especially those with a higher incidence in population. considering that disease patterns vary from region to region and there is no...

Neoplasms of the skin can be hard to differentiate clinically, but nevertheless they can result in entirely different consequences. While the colloquially called “white skin cancer” describes rather harmless changes of the skin, the “black skin” cancer is feared. As other doctors from different specialties, other than dermatologist, are also consulted when discussing diagnostic findings of thei...

studies undertaken during the last 5 years in the babol research station of the institute of public health research, teheran university, with the collaboration of the international agency for research on cancer in the caspian littoral and ardabil area in the north of iran has indicated the presence of cancer in 48 different sites. the five more prevalent types of cancer found in that area in or...

The human skin papillomaviruses (HPVs) represent a group of ubiquitous viruses detected at a high prevalence in the normal skin of healthy adults. In the present study, we analyzed skin swab samples from babies during their first days of life and from infants at various ages up to age 4 years. Specimens from their parents and, for the newborn babies, environmental samples were also investigated...

In this review the potential application of near-infrared spectroscopy for the in vitro and in vivo characterization of skin is presented. The near-infrared attenuated reflectance spectroscopy allows the determination of the overall skin water content as well as of the various components constituting the skin, i.e., stratum corneum, epidermis and dermis. This technique provides the possibility ...
