Although not generally recommended, scheduled central venous catheter (CVC) removal is sometimes carried out in order to reduce the CVC-related bloodstream infection (CRBSI) incidence. We conducted a simulation for scheduled CVC removal within the multicenter CRBSI registry (SECRECY). Non-tunneled jugular and subclavian CVC in patients with hematological disease or with germ cell tumors (including patients receiving autologous stem cell transplantation [SCT]) were included. Cases were randomized in a 1:1:1:1 ratio to either a simulated, scheduled CVC removal after 7, 14, and 21 days, or to non-simulated, unscheduled CVC removal (control group). The primary endpoint was definitive CRBSI incidence for a scheduled CVC removal after 14 days (dCRBSI-D14rmv). Among other, secondary endpoints were definite CRBSI incidence for a scheduled removal after 7 days (dCRBSI-D7rmv) and 21 days (dCRBSI-D21rmv). Data on 2984 CVC were included. Patients’ median age was 59 (range 16–95) years, 58.8% being male. The vast majority (98.4%) were patients with hematological malignancies. Jugular veins were the main insertion site (93.2%). dCRBSI-D14rmv was 3.10/1000 CVC days as compared to 4.15/1000 CVC days in the control group (p = 0.23). There was a significant difference between dCRBSI-D7rmv (0.86/1000 CVC days) and controls (p < 0.001), but not between dCRBSI-D21rmv (4.10/1000 CVC days) and controls (p = 0.96). Our data suggest that in patients with hematological diseases or autologous SCT recipients scheduled CVC removal after 14 days does not result in a lower CRBSI incidence compared to unscheduled removal.Trial registration: DRKS00006551, 2014/09/29, retrospectively registered.

Of 804 surgically treated parotid gland tumours, every fifth (19.9%) was situated medially from the 8th cranial nerve. Among these deep lobe tumours (DLT) there are more malignant tumours (36.8%) than in superficial lobe tumours (SLT; 11.4%). This fits especially the carcinoma arising in pleomorphic adenomas (14.3% in DLT; 3.1% in SLT). Postoperative complications of the 8th cranial nerve, defective tumour capsules, and necessary second or third look operations are more frequently in DLT than with SLT. Early diagnosis of tumours that are still small, is therefore very important.
