Perineal trauma after vaginal birth is common and can be associated with short- and long-term health problems. Perineal hyaluronidase (HAase) injection has been widely used to reduce perineal trauma, perineal pain and the need for episiotomy since the 1950s. The administration of HAase is considered to be a simple, low risk, low cost and effective way to decrease perineal trauma without causing adverse effects. ⋯ Perineal HAase injection during the second stage of labour may result in a lower incidence of perineal trauma (tears or episiotomy, or both) compared with no intervention, but not compared with placebo injection, in women having a vaginal delivery. Meanwhile, perineal HAase injection likely reduces the incidence of perineal oedema 24 hours after vaginal delivery compared with placebo injection. The potential use of perineal HAase injection as a method to reduce perineal trauma and perineal oedema remains to be determined as the number of high-quality trials and outcomes reported was too limited to draw conclusions on its effectiveness and safety. Further rigorous randomised controlled trials are required to evaluate the role of perineal HAase injection in vaginal deliveries, including evaluating whether there is any differential effect based on the dose, frequency and positioning of HAase injection.

Review Meta AnalysisTranexamic acid for preventing postpartum haemorrhage after caesarean section.
Postpartum haemorrhage (PPH) is common and potentially life-threatening. The antifibrinolytic drug tranexamic acid (TXA) is recommended for treating PPH; it reduces the risk of death from haemorrhage by one-third when given soon after bleeding onset, but not overall risk of death. Interest in whether TXA may be effective in preventing PPH is growing. Evidence indicates that TXA given more than three hours after injury to bleeding trauma patients increases mortality. Potential harm becomes critical in prophylactic use of TXA. Reliable evidence of the effect and safety profile of TXA is required before widespread prophylactic use can be considered. ⋯ The published protocol and updates to the review can be accessed: Protocol (2009) DOI: 10.1002/14651858.CD007872 Original Review (2010) DOI: 10.1002/14651858.CD007872.pub2 Review Update (2015) DOI: 10.1002/14651858.CD007872.pub3.

Support for parents and families after stillbirth and neonatal death.
This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To identify and assess the effect of support interventions focused on psychological, social, and emotional outcomes for bereaved parents (including birth and non-birthing mothers, fathers, partners) and family members of parents (e.g. grandparents; siblings) who have experienced stillbirth or neonatal death.

Review Meta AnalysisNon-corticosteroid immunosuppressive medications for steroid-sensitive nephrotic syndrome in children.
About 80% of children with steroid-sensitive nephrotic syndrome (SSNS) have relapses. Of these children, half will relapse frequently, and are at risk of adverse effects from corticosteroids. While non-corticosteroid immunosuppressive medications prolong periods of remission, they have significant potential adverse effects. Currently, there is no consensus about the most appropriate second-line agent in children with frequently relapsing SSNS. In addition, these medications could be used with corticosteroids in the initial episode of SSNS to prolong the period of remission. This is the fifth update of a review first published in 2001 and updated in 2005, 2008, 2013 and 2020. ⋯ New studies incorporated in this review update indicate that rituximab compared with prednisone, tacrolimus, or MMF is a valuable additional agent for managing children with relapsing SSNS. Comparative studies of CNIs, MMF, and levamisole suggest that CNIs may be more effective than MMF and that levamisole may be similar in efficacy to MMF. Important new studies suggest that MMF prolongs remission following rituximab, that levamisole may prevent infection-related relapse more effectively than changing from alternate-day to daily prednisone and that levamisole and prednisone compared with prednisone alone may prolong the time to first relapse. There are currently 23 ongoing studies which should improve our understanding of how to treat children with frequently relapsing SSNS.
