Frequent chromosomal gains in recurrent juvenile nasopharyngeal angiofibroma.

2007

Juvenile nasopharyngeal angiofibroma (JNA) is a rare benign tumor, mostly affecting adolescent males. Some patients develop recurrences after surgery independently of completeness of removal. Only very limited data concerning underlying chromosomal changes are available. We therefore analyzed samples of 22 JNAs, including six recurrences, with comparative genomic hybridization (CGH). Additionally, quantitative image cytometry was used for measurement of DNA aneuploidy in representative samples. Of the 13 primary JNAs without later recurrence, DNA gains were identified on autosomes in only two samples. Four patients with one or two recurrences were included in the study; for one of these, no…

ELS live surgery: a developing story

2019

Since 2015, the European Laryngological Society (ELS) has organized on a yearly basis the European Laryngological Live Surgery Broadcast. The goal of this paper is to demonstrate the increasing worldwide audience. The number of individual computers logged in, number of estimated audience, and number of countries with an active audience were calculated and compared to the numbers in 2015. In 2018, 19 live interventions were performed in three parallel sessions. The surgeons worked in 10 departments in 8 different countries. The number of individual computers logged in increased from 1000 in 2015 to 16000 in 2018. The estimated audience increased from 3000 to 32000 visitors. The number of cou…
