Low back pain (LBP) is a common disorder affecting an increasing number of people worldwide, whose diagnosis is focused on the identification of triggering causes. First line therapy usually starts from conservative approaches, whereas second line treatments include a spectrum of minimally invasive techniques, before resorting to more invasive surgical approaches. Among minimally invasive techniques, percutaneous oxygen-ozone injections represent one of the most common and cost-effective procedures. Aim of this study is to provide a metanalysis on literature evidences on percutaneous oxygen-ozone injections, comparing image-guided to non-image-guided techniques for LBP treatment. Imaging-guided procedures showed better performances compared to non-image-guided techniques based only on anatomical landmarks, with higher therapeutic efficacy and lower age-related variability in clinical results.

Objective: Long term intravenous access in paediatrics is challenging in terms of ease of procedure, maintenance of catheter and complications. Small calibre of peripheral veins in children make insertion of peripheral long-term access difficult. Our centre adopted the use of tunneled adult Peripherally Inserted Central Catheter (PICC) for central venous access in paediatrics with the hope to improve these challenges. We describe a single institute 3-year experience of this technique. Material & Methods: Retrospective analysis of patients aged less than 12 years old who had tunneled PICC insertions from January 2018 till December 2020. The following data was recorded and studied: indication, reason for removal, duration of PICC, vessel inserted, device type and complications. Results: Eleven adult PICCs were inserted from this technique in 10 children. The average age was 35.7months and weight was 13.2kg. The youngest patient was 3 months old at 6.9kg. Most common indication for insertion was for long term antibiotics (82%) and the remainder were for difficult intravenous access. The procedure was done under local anaesthetic with sedation in 90% of cases. Average duration of PICC was 26.8 days. Out of 11 PICCs only 1 had line related infection that required premature removal of the catheter. 55% completed the intended duration while 27% of PICCs had dislodged. Conclusion: Tunnelled adult PICC for central venous access in paediatrics is a feasible option for long term vascular access and has a lower risk of infection. However, almost a third of the catheters inserted still suffered premature dislodgement.
