The efficacy of sacral nerve stimulation (SNS) to treat faecal incontinence has been demonstrated in the short- and mid-term. We analysed SNS outcome first patients with a permanent neurostimulator whom follow-up ranges up 14 years.Of 12 who underwent from 1994 1999, 9 were eligible for long-term analysis (defined as minimum 7 years). In 3 device had be removed because pain or neurological disease. Functional was monitored prospectively by standardized questionnaire. For efficacy, recorded...

Small blue round cell sarcomas (SBRCSs) are a heterogeneous group of tumors with overlapping morphologic features but markedly varying prognosis. They characterized by distinct chromosomal alterations, particularly rearrangements leading to gene fusions, whose detection currently represents the most reliable diagnostic marker. Ewing (ESs) common SBRCSs, defined fusions involving EWSR1 and transcription factors ETS family, while frequent non-EWSR1-rearranged SBRCSs harbor CIC rearrangement....
