Two patients presented with papular eruptions that could not be diagnosed clinically. Biopsies of these lesions showed eosinophilic pustular folliculitis (EPF). Both cases were subsequently found to have infestations: one as a result of cutaneous larva migrans was successfully treated with ivermectin and the other caused by scabies mites was successfully treated with topical pyrethrin. The two cases of EPF presented emphasize the need for careful clinicopathological correlation to determine the cause.
A 46 year old man with Crohn's disease developed a widespread pustular eruption associated with intermittent fever and arthritis. Histological examination demonstrated cutaneous vasculitis with leukocytoclasia, and IgM and C3 on direct immunofluorescence. This is characteristic of the bowel-associated dermatosis-arthritis syndrome, also known as the bowel bypass syndrome without bypass, a recently described complication of inflammatory bowel disease. This is the ninth case reported to date.
The compound 1,2-benzisothiazolin-3-one (BIT) is the active ingredient in Proxel GXL a commonly used preservative in many industries. The present case report identifies the carpet industry as an additional source of occupational allergic contact dermatitis to BIT.
Allergic contact dermatitis to garlic usually has a typical clinical presentation but this is often masked if it presents concurrently with another form of hand dermatitis. Patch testing with 1% diallyl disulfide in petrolatum is recommended when garlic allergy is suspected.
There are many reasons to believe that oral participation in the target language (TL) is beneficial for classroom language learners. In addition to the prominence current second language acquisition (SLA) theory gives to processes that assume learner production of the TL (e.g. negotiation of meaning), teachers often view oral participation as a measure of learner involvement. Thus, it is often assumed that learners who participate often are likely to make greater proficiency gains. This correlational study examined this assumption by investigating the relationship between learners’ oral participation in classes for English as a foreign language (EFL) at a Japanese university and their gains in TL proficiency. Results indicated that while the quality of learners’ participation (accuracy, complexity, and fluency) was positively related to gains in TL ability, quantity of participation was not. While not indicative of a cause–effect relationship, the results suggest that teachers might wish to consider encouraging quality of participation as well as quantity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
