Review Meta AnalysisComputer-assisted surgery for knee ligament reconstruction.
Anterior cruciate ligament (ACL) reconstruction is one of the most frequently performed orthopaedic procedures. The most common technical cause of reconstruction failure is graft malpositioning. Computer-assisted surgery (CAS) aims to improve the accuracy of graft placement. Although posterior cruciate ligament (PCL) injury and reconstruction are far less common, PCL reconstruction has comparable difficulties relating to graft placement. This is an update of a Cochrane review first published in 2011. ⋯ From the available evidence, we are unable to demonstrate or refute a favourable effect of CAS for cruciate ligament reconstructions of the knee compared with conventional reconstructions. However, the currently available evidence does not indicate that CAS in knee ligament reconstruction improves outcome. There is a need for improved reporting of future studies of this technology.

Botulism is an acute paralytic illness caused by a neurotoxin produced by Clostridium botulinum. Supportive care, including intensive care, is key but the role of other medical treatments is unclear. This is an update of a review first published in 2011. ⋯ There is evidence supporting the use of human-derived botulinum immune globulin (BIG) in infant intestinal botulism. A single randomized controlled trial demonstrated significant decreases in the duration of hospitalization, mechanical ventilation and tube or parenteral feeding with BIG treatment. This evidence was of moderate quality for effects on duration of mechanical ventilation but was otherwise of high quality. Our search did not reveal any evidence examining the use of other medical treatments including serum trivalent botulism antitoxin.

Review Meta AnalysisSystemic antibiotics for symptomatic apical periodontitis and acute apical abscess in adults.
Dental pain can have a considerable detrimental effect on an individual's quality of life. Symptomatic apical periodontitis and acute apical abscess are common causes of dental pain and arise from an inflamed or necrotic dental pulp, or infection of the pulpless root canal system. Clinical guidelines recommend that the first-line treatment for teeth with symptomatic apical periodontitis or an acute apical abscess should be removal of the source of inflammation or infection by local, operative measures, and that systemic antibiotics are currently only recommended for situations where there is evidence of spreading infection (cellulitis, lymph node involvement, diffuse swelling) or systemic involvement (fever, malaise). Despite this, there is evidence that dentists continue to prescribe antibiotics for these conditions. There is concern that this could contribute to the development of antibiotic-resistant bacterial colonies both within the individual and within the community as a whole. ⋯ There is very low quality evidence that is insufficient to determine the effects of systemic antibiotics on adults with symptomatic apical periodontitis or acute apical abscess.

ReviewRegular long-term red blood cell transfusions for managing chronic chest complications in sickle cell disease.
Sickle cell disease can cause severe vaso-occlusive crises and dysfunction of most organ systems. The two most common chronic chest complications due to sickle cell disease are pulmonary hypertension and chronic sickle lung disease. These complications can lead to morbidity (such as reduced exercise tolerance) and increased mortality. ⋯ There is a need for randomized controlled trials looking at the role of long-term transfusion therapy in pulmonary hypertension and chronic sickle lung disease. Due to the chronic nature of the conditions, such trials should aim to use a combination of objective and subjective measures to assess participants during an extended 'steady state' baseline, and after the intervention.

Review Meta AnalysisAnticoagulation for the long-term treatment of venous thromboembolism in patients with cancer.
Cancer increases the risk of thromboembolic events in patients including those receiving anticoagulation treatments. ⋯ For the long-term treatment of VTE in patients with cancer, LMWH compared with VKA reduces venous thromboembolic events but not mortality. The decision for a patient with cancer and VTE to start long-term LMWH versus oral anticoagulation should balance the benefits and harms and integrate the patient's values and preferences for the important outcomes and alternative management strategies.
