The Diagnostic Yield of Histopathologic Sampling Techniques in PAN-Associated Cutaneous Ulcers

Abstract: Table 1. No statistically significant differences were found between scans evaluated by the 2 investigators about wound area and volume. The relative errors and the intraclass correlation coefficients are reported in Table 2. The ICC values were excellent for both intrarater and interrater reproducibility with a very low relative error value. The mean ± SD time for a full scan acquisition on the wound area and volume was 3.6 ± 1.4 minutes.Comment. The laser scanner system used in this study enables users to ac… Show more

“…All but one woman healed within 3 weeks; the exception was an RTR with persistent ulceration, underscoring the role of host immunity in the pathogenesis of EBVVU. The almost 100% prevalence of arteritis, histopathology that correlates with punched-out ulcers, 8,31,32 further highlights the existence of immunopathology and incriminates EBV as the putative target of the host immune response.…”

“…Timing of biopsy and failure to include the deep submucosa-subcutis can explain a lower frequency of vasculitis, more specifically arteritis, reported in the literature. 8,31,32 Detection of EBV DNA by PCR was found in 4 of 6 biopsies tested (67%). 5,16,19,20,23,25 In 3 of 4 specimens showing vasculitis, PCR detected EBV DNA.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…Nur so können die betroffen Arteriolen und mittelgroßen Arterien der dermo-dermalen Junktionszone und Subkutis erfasst werden. Der häufigste Grund für eine Wiederholung der Gewebeentnahme bei Patienten mit einer kutanen PAN ist die unzureichende Menge an Gewebe für eine aussagekräftige histologische Untersuchung [21]. Auch wenn bei der PAN typischerweise mittelgroße Gefäße betroffen sind, können ebenfalls kleine Gefäße der Dermis betroffen sein und daher gerade bei zu oberflächlicher Biopsie eine Immunkomplexvasculitis der kleineren Gefäße vortäuschen.…”
