The purpose of this study was to use a validated rabbit model to assess the effects on surgically-induced knee joint contractures of two combined pharmacological interventions celecoxib (CXB) loaded on an implanted collagen membrane, and subcutaneously (SQ) injected ketotifen. Thirty rabbits were randomly divided into five groups. The first group received no intervention after the index surgery. The remaining four groups underwent intra-articular implantation of collagen membranes loaded with or without CXB at the time of the index surgery; two of which were also treated with SQ ketotifen. Biomechanical joint contracture data were collected at 8, 10, 16, and 24 weeks. At the time of necropsy (24 weeks), posterior capsule tissue was collected for messenger RNA and histopathologic analyses. At 24 weeks, there was a statistically significant increase in passive extension am life for patients with this debilitating condition. © 2020 Orthopaedic Research Society.

To investigate whether HLHS incident rates in Poland are seasonally variable. METHODS Data on 791 cases of HLHS from the Registry collected between 2004 and 2016 was analyzed. RESULTS The median gestational age for the 734 cases of HLHS detected was 23 weeks. Comparing the age at time of HLHS detection between 2004 and 2016, a decrease from 26 to 20.8 weeks was observed. We noted a rapid increase in HLHS incidence during the initial years of the Registry data, the annual percentage change during that period was 22.0% and this trend lasted until 2010. In the following years, the Registry becam
