the family of staphylinidae (rove beetles) includes 40000 species and has a world-wide distribution . many species of paederus have been known for a long time as the causative agent of linear dermatitis. paederus beetles are attracted to artificial lights in the evening during the hot and humid summer nights. whenever they are crashed or smeared on the skin they release their toxin called pede...

background: linear dermatitis is endemic in iran where most cases occur in the caspian sea coast and fars prov­ince. the disease is caused by beetles of the genus paederus which are active from early spring to beginning of au­tumn although its incidence rises from may to august. the classic taxonomy of paederus spp. is based on the male genitalia that is very complex and needs expertise. in thi...

the present study was performed during spring, summer and fall of 1997 in the central and western parts of fars province, iran, led to identification of paederus ilsae bernhauer and paederus iliensis coiffait (col: staphylinidae). this is the first original report of the latter species from iran. the adults have 5 months activity in average, begin lately in april and then continue until early s...

Palisaded granulomatous dermatitis is an uncommon pathologic condition potentially associated with several disorders. These include drugs, inflammatory bowel disease, multiple myelomas, rheumatoid arthritis, and systemic lupus erythematosus. An illustrative case of a man with palisaded granulomatous dermatitis who subsequently developed ulcerative colitis is described, and the characteristics o...

The linear ubiquitin chain assembly complex (LUBAC) ubiquitin ligase complex, composed of HOIL-1L-interacting protein (HOIP), heme-oxidized IRP2 ubiquitin ligase-1L (HOIL-1L), and SHANK-associated RH domain protein, specifically generates linear polyubiquitin chains and is involved in NF-κB activation. Lack of SHANK-associated RH domain protein, which drastically reduces the amount of HOIP and ...

Use dermoscope to identify inflammatory dermatoses with facial erythema as the main feature and other atypical clinical manifestations. By reviewing data dermoscopic images of outpatients in our hospital, four diseases rosacea, seborrheic dermatitis, contact dermatitis atopic were screened out, their characteristics obtained: Rosacea is a diffuse distribution polygonal blood vessels on red or p...

skin disorders comprise more than 35% of all occupationally related diseases. 90-95% of work-related dermatoses are contact dermatitis. effects of occupational dermatitis in the lives of workers are substantial. to plan any preventive program we need basic statistics of the problem, that we had no reliable one which includes a lot of industries in iran. therefore we decided to determine occupat...
