We implemented the individualized treatment (IT) regimen for children with inguinal hernia and the Lichtenstein hernioplasty using an acellular tissue matrix patch (LHAP) for those with high risks. This retrospective study compares the complications of conventional laparoscopic high hernia sac ligation (LHSL) with those of the IT regimen for the management of pediatric inguinal hernia and investigates whether the recurrence rate of inguinal hernias in children treated by IT is lower than that of those treated by LHSL. The subjects of this retrospective study were 3006 children who underwent LHSL or IT for inguinal hernia between February, 2008 and February, 2016 at the Beijing Chao-Yang Hospital (Beijing, China). They comprised 1516 (50.4%) children who underwent LHSL between February, 2008 and December, 2012, and 1490 (49.6%) who underwent IT between January, 2013 and June, 2016. We analyzed the patients' data, including clinical characteristics and postoperative complications. The mean follow-up was 85.31 months for the LHSL group and 43.34 months for the IT group (P

This study is to establish a rabbit model for human prosthetic joint infection and biofilm formation. Thirty-two healthy adult rabbits were randomly divided into four groups and implanted with stainless steel screws and ultra-high molecular weight polyethylene (UHMWPE) washers in the non-articular surface of the femoral lateral condyle of the right hind knees. The rabbit knee joints were inoculated with 1 mL saline containing 0, 102, 103, 104 CFU of Staphylococcus epidermidis (S. epidermidis) isolated from the patient with total knee arthroplasty (TKA) infection, respectively. On the 14th postoperative day, the UHMWPE washers from the optimal 103 CFU group were further examined. The SEM examination showed a typical biofilm construction that circular S. epidermidis were embedded in a mucous-like matrix. In addition, the LCSM examination showed that the biofilm consisted of the polysaccharide stained bright green fluorescence and S. epidermidis radiating red fluorescence. Thus, we successfully create a rabbit model for prosthetic joint infection and biofilm formation, which should be valuable for biofilm studies.
