The two major forms of contact dermatitis are irritant contact dermatitis and allergic contact dermatitis. Irritant contact dermatitis is seen in roughly 80% of contact dermatitis cases.1 Irritant contact dermatitis is an inflammatory, but nonimmunologic doseand time-dependent skin response to direct cellular injury caused by a skin irritant, and it does not require prior sensitization.2,3 Comm...

orf is a mucocutaneous disease that occurs when non-intact skin comes into contact with contaminated sheep saliva. the lesions may complicate to lymphangitis or secondary bacterial infection, but systemic complications such as erythema multiforme, maculopapular rash, and generalized lymphadenopathy are rare. in this paper, we present two cases of erythema multiforme following orf disease.

BACKGROUND It is well established that UV radiation provokes an immunological depletion in the skin, enabling the development of malignant cutaneous tumors. Most nonmelanoma skin cancer patients are considered to be UVB-susceptible. OBJECTIVE To study the behavior of UVB- susceptibility in malignant melanoma (MM) patients and whether this is a risk factor to the development of MM. METHODS E...

Current diagnostic methods for skin cancers are based on some morphological characteristics of the pigmented skin lesions, including the geometry of their contour. The aim of this article is to model the early growth of melanoma accounting for the biomechanical characteristics of the tumor micro-environment, and evaluating their influence on the tumor morphology and its evolution. The spatial d...

The problem of electrical impedance between the skin and the electrode is an on-going challenge in bio-electronics. This is particularly true in the case of Electrical Impedance Tomography (EIT), which uses a large number of skin-contact electrodes and is very sensitive to noise. In the present article, contact impedance is measured and compared for a range of electrodes placed on the thorax of...

BACKGROUND The ability of novices to perform imaging of skin lesions is not well studied. OBJECTIVES To determine the ability of 12th grade high school students without formal training to take clinical and dermatoscopic images of skin lesions on patient-actors. PATIENTS/METHODS Nineteen participants were divided into 11 gender-specific groups of 1-2 students. Groups were provided written in...

OBJECTIVE The purpose of this study was to explore the association between tuberculin reaction size in contacts with positive tuberculin skin test results and a variety of contact and index patient variables. PATIENTS AND METHODS We reviewed the contact investigation records for tuberculosis patients identified by the Tuberculosis Prevention and Control Center of Lleida, Spain, over a period ...

conclusions a higher number of bacterial flora was found in the bodybuilders particularly those using aas in comparison to the controls, which might be due to the influence of these aas on the skin microflora and transmission of the bacteria through the direct contact of the naked skin with the exercise instruments. background anabolic-androgenic steroids (aas) abuse by the athletes has dramati...
