Background: Cell-mediated immunity (CMI) plays an important role in resistance against leishmaniasis. Leishmanin test (Montenegro skin test) is a method in evaluation of immune system reaction against cutaneous leishmaniasis. The TDR/WHO reference Leishmanin produced by the Pasteur Institute of Iran is used worldwide. Two other antigens produced by Razi Serum Institute of Iran, Killed Leishmani...

The three skin disorders of Lyme borreliosis in Europe include erythema migrans, an acute, self-limited lesion; borrelial lymphocytoma, a subacute lesion; and acrodermatitis chronica atrophicans, a chronic lesion. Using quantitative reverse transcription-PCR, we determined mRNA expression of selected chemokines, cytokines, and leukocyte markers in skin samples from 100 patients with erythema mi...

We have investigated the photoprotective properties of tanning using erythema as an endpoint. Previously unexposed buttock skin sites of 16 young, healthy adults (8 skin type II, and 8 skin type III) were exposed daily (Mon-Fri) for 2 weeks to 0.5 and 0.75 minimal erythema doses (MED) of solar-simulated radiation (SSR). Erythema and melanin levels were assessed daily both visually and quantitat...

Cancer chemopreventive effects of polyphenols from green tea (GTP) in mouse models of photocarcinogenesis are established. The present study is extended from mouse model to human system in vivo to determine the effect of topical application of GTP to human individuals against UV light-induced DNA damage in the form of cyclobutane pyrimidine dimers (CPDs) in the skin. UVB-induced CPDs were detec...

Benztropine, an anticholinergic drug, caused a number of skin changes only in the areas of the body that previously had demonstrated clinical symptoms of multiple sclerosis (MS). These changes included erythema, telangiectasias, non-pitting edema and flaky/scaly skin. Despite continuation of the benztropine, the skin changes eventually resolved. However, a few months later, minimal erythema and...

Ultraviolet radiation (UVR) has a significant impact on human skin and is the major environmental factor for skin cancer formation. It is also believed that 80% of the signs of skin aging are attributed to UVR. UVR induces inflammatory changes in the skin via the increase in oxidative stress, DNA damage vascular permeability, and fluctuation in a myriad of cytokines. Acutely, UVR causes skin in...

Erythema multiforme is an acute mucocutaneous disorder, characterized by varying degrees of blistering and ulceration. We report a case of recurrent herpes-associated erythema multiforme managed with prophylactic acyclovir. An 11-year-old boy had lesions in the oral cavity and lips, which had been diagnosed as erythema multiforme minor. Four months later, the patient had desquamative gingivitis...

OBJECTIVE To objectively measure the change in size of the wheal or erythema resulting from the skin prick test. DESIGN Prospective randomized trial involving patients with allergic rhinitis recruited from March 8, 2009, through August 21, 2009, in Seoul, South Korea. SETTING Otorhinolaryngology clinic of a university hospital. PATIENTS Of 69 patients suspected of having allergic rhinitis...

Erythema multiforme major was diagnosed in a dog with necrotizing parvoviral enteritis. Skin lesions consisted of ulceration of the footpads, pressure points, mouth, and vaginal mucosa; vesicles in the oral cavity; and erythematous patches on the abdomen and perivulvar skin. Microscopic examination of mucosal and haired skin specimens revealed lymphocyte-associated keratinocyte apoptosis at var...
