19. Vicryl PG-910 "Minimal to slight foreign body responses have been routinely seen in multiple preclinical tissue reaction studies with VICRYL suture (usually muscle implantation), a typical tissue response to a foreign body that on occasion included foreign body giant cells. The tissue responses were not excessive and were considered a normal response to a foreign body." Dr Jim Oldham, pre-clinical safety group. Geraldine Harkins Marketing Manager ETHICON Products UK August 2008 In regard to internal sutures Pg-910 showed a 66% increase In risk when compared to PGA Gabrielli et al 2001 Plastic & Reconstructive surgery Vol.107, No 1 pp 40

20. Allergenic tendency steroid Haematoma Infection Suture reaction enhanced Allergies: in last case triadcortyl, aminophyliine, antzoline hydrozyzine Hcl, mepyramine malleate, piperazine, neomycin, bacitracin, soframycin, gentamycin and kanamycin

21. Conclusion We need to be clearer when describing wound problems Not all wounds lead to complications Haematomata may not be obvious for 21 days Steroids may compound haematoma effects PG-910 reaction is accelerated with haematoma Infection remains unproven
