DEMONSTRATION OF THE GENUINE ISO-12P CHARACTER OF THE STANDARD MARKER CHROMOSOME OF TESTICULAR GERM-CELL TUMORS AND IDENTIFICATION OF FURTHER CHROMOSOME-12 ABERRATIONS BY COMPETITIVE INSITU HYBRIDIZATION
DEMONSTRATION OF THE GENUINE ISO-12P CHARACTER OF THE STANDARD MARKER CHROMOSOME OF TESTICULAR GERM-CELL TUMORS AND IDENTIFICATION OF FURTHER CHROMOSOME-12 ABERRATIONS BY COMPETITIVE INSITU HYBRIDIZATION
The recently developed competitive in situ hybridization (CISH) strategy was applied to the analysis of chromosome 12 aberrations in testicular germ cell tumors (TGCTs). DNAs from two rodent-human somatic cell hybrids, containing either a normal chromosome 12 or the p arm of chromosome 12 as their unique human material, were used as probes. Our results demonstrate a genuine iso-12p character of the standard marker chromosome in TGCTs. Moreover, variant markers were identified representing translocation products that also involve chromosome 12

Common surgical procedures in pilonidal sinus disease: A meta-analysis, merged data analysis, and comprehensive study on recurrence
Abstract We systematically searched available databases. We reviewed 6,143 studies published from 1833 to 2017. Reports in English, French, German, Italian, and Spanish were considered, as were publications in other languages if definitive treatment and recurrence at specific follow-up times were described in an English abstract. We assessed data in the manner of a meta-analysis of RCTs; further we assessed non-RCTs in the manner of a merged data analysis. In the RCT analysis including 11,730 patients, Limberg & Dufourmentel operations were associated with low recurrence of 0.6% (95%CI 0.3–0.9%) 12 months and 1.8% (95%CI 1.1–2.4%) respectively 24 months postoperatively. Analysing 89,583 patients from RCTs and non-RCTs, the Karydakis & Bascom approaches were associated with recurrence of only 0.2% (95%CI 0.1–0.3%) 12 months and 0.6% (95%CI 0.5–0.8%) 24 months postoperatively. Primary midline closure exhibited long-term recurrence up to 67.9% (95%CI 53.3–82.4%) 240 months post-surgery. For most procedures, only a few RCTs without long term follow up data exist, but substitute data from numerous non-RCTs are available. Recurrence in PSD is highly dependent on surgical procedure and by follow-up time; both must be considered when drawing conclusions regarding the efficacy of a procedure
