Background The internet is an increasingly utilised resource for accessing information regarding a variety of heath conditions. YouTube is a popular video sharing platform used to both seek and distribute information online. A search for ‘scoliosis’ was carried out using YouTube's search engine and data was collected on the first fifty videos returned. A JAMA score (to determine currency, authorship, source and disclosure) and scoliosis specific score (that measures the amount of information on the diagnosis and treatment options as devised by Mathur et al in 2005; scored 0–32) was recorded for each video to measure quality objectively. Additionally the number of views, number of comments and feedback positivity was documented for each. Data analysis was conducted using R 3.1.4/R Studio 0.98 with control for the age of each video in analysis models. The average number of views per video was 71,152 with an average length of 7 minutes 32 seconds. Thirty six percent of the videos fell under the authorship category of personal experience. The average JAMA score was 1.32/4 and average scoliosis specific score was 5.38/32. There was a positive correlation between JAMA score and number of views P=0.003. However in contrast there was a negative correlation between scoliosis specific score and number of views P=0.01.Materials & Methods
Results
Local anaesthetic has been reported to have a potentially detrimental effect on human chondrocytes both in vitro and in vivo. Due to chondroproliferative effects, magnesium may be an alternative intra-articular analgesic agent following arthroscopy. We aimed to examine the dose response effect of commonly used local anaesthetics on chondrocyte viability and also to report on the effect of adding magnesium to the local anesthetic agent. Human chondrocytes were grown under standard culture conditions. Cells were exposed to either lignocaine (0.5, 1, 2%), levobupivacaine (0.125, 0.25, 0.5%), bupivacaine (0.125, 0.25, 0.5%) or ropivacaine (0.1875, 0.375, 0.75%) for 15 minutes. Cells were also exposed to a local anesthetic agent with the addition of magnesium (10, 20, or 50%). Cells exposed to culture media or saline served as controls. The MTS assay was used to assess cell viability 24 hours after exposure. One-way ANOVA were used to test for statistical significance.Introduction
