Annular urticarial lesions in a child must establish a main differential diagnosis with urticaria multiforme, common urticaria, acute hemorrhagic edema of infancy, erythema marginatum, erythema annulare centrifugum, annular erythema in childhood, erythema multiforme, Sweet's syndrome, Schönlein-Henoch purpura, erythematosus lupus, several systemic vasculitis, and serum sickness.

The objectives of this study were to determine the diversity, seasonal dynamics and abundance of ticks infesting cattle in Isfahan zone, Iran. The study was conducted in three traditional cattle farms. No acaricides had been applied to cattle at the selected farms. Adult ticks were collected twice per month from different parts of the cattle's body. Environmental data, including relative humidi...

Tick-borne diseases pose a serious threat to human health in South-Eastern Europe, including Kosovo. While Crimean-Congo hemorrhagic fever (CCHF) is a well-known emerging infection in this area, there are no accurate data on Lyme borreliosis and tick-borne encephalitis (TBE). Therefore, we sampled and tested 795 ticks. Ixodes ricinus (n = 218), Dermacentor marginatus (n = 98), and Haemaphysalis...

BACKGROUND/OBJECTIVES Abundant consumption of seaweeds in the diet is epidemiologically linked to the reduction in risk of developing cancer. In larger cases, however, identification of particular seaweeds that are accountable for these effects is still lacking, hindering the recognition of competent dietary-based chemo preventive approaches. The aim of this research was to establish the antipr...

Sequences from the Anaplasma phagocytophilum 16S rRNA gene were detected in 5 ticks representing 3 species (Hyalomma marginatum, Rhipicephalus turanicus, and Boophilus kohlsi) collected from roe deer (Capreolus capreolus) in Mount Carmel, Israel. The sequences were all identical to those of Ap-variant 1 strain.

Keratoacanthoma centrifugum marginatum (KCM) is a rare variant of keratoacanthoma (KA). It is characterized by a progressive peripheral expansion and central healing leaving atrophic scar. It is sometimes confused with squamous cell carcinoma (SCC) both clinically and histopathologically. We here report a case of KCM over the extensor aspect of the right forearm in a 57-year-old man with an abn...

background: rhipicephalus sanguineus and hyalomma marginatum are the most common spe­cies in sheep herds in northeast of iran. there is preliminary evidence that these species may be the vectors of babesia ovis in iran. we carried out two experiments in mashhad area, khorasan razavi province to determine whether b. ovis could be transovarially transmitted by r. san­guineus and h. marginatum . m...

An outbreak of lameness amongst Merino lambs, associated with the presence of Hyalomma ticks, was investigated on a farm in the south-western Free State, South Africa. The purpose was to follow the progress of the condition and to determine the extent of involvement of the two Hyalomma species which occur in the region. The flock of experimental sheep (n = 460) ranged free in natural veld under...
