Review Meta AnalysisPain management for tubal sterilization by hysteroscopy.
Tubal sterilization by hysteroscopy involves inserting a foreign body in both fallopian tubes. Over a three-month period, the tubal lumen is occluded by tissue growth stimulated by the insert. Tubal sterilization by hysteroscopy has advantages over laparoscopy or mini-laparotomy, including the avoidance of abdominal incisions and the convenience of performing the procedure in an office-based setting. Pain, an important determinant of procedure acceptability, can be a concern when tubal sterilization is performed in the office. ⋯ The available literature is insufficient to determine the appropriate analgesia or anesthesia for sterilization by hysteroscopy. Compared to paracervical block with normal saline, paracervical block with lidocaine reduced pain during some portions of the procedure. Intravenous sedation resulted in lower pain scores during insertion of the second tubal device. However, neither paracervical block with lidocaine nor conscious sedation significantly reduced overall pain scores for sterilization by hysteroscopy.

Review Meta AnalysisBotulinum toxin for the treatment of strabismus.
The use of botulinum toxin as an investigative and treatment modality for strabismus is well reported in the medical literature. However it is unclear how effective its use is in comparison to other treatment options for strabismus. ⋯ The majority of published literature on the use of botulinum toxin in the treatment of strabismus consists of retrospective studies, cohort studies or case reviews. Although these provide useful descriptive information, clarification is required as to the effective use of botulinum toxin as an independent treatment modality. Four RCTs on the therapeutic use of botulinum toxin in strabismus have shown varying responses ranging from a lack of evidence for prophylactic effect of botulinum toxin in acute sixth nerve palsy, to poor response in patients with horizontal strabismus without binocular vision, to no difference in response in patients that required retreatment for acquired esotropia or infantile esotropia. It was not possible to establish dose effect information. Complication rates for use of Botox™ or Dysport™ ranged from 24% to 55.54%.

Review Meta AnalysisInhaled versus systemic corticosteroids for preventing chronic lung disease in ventilated very low birth weight preterm neonates.
Chronic lung disease (CLD) remains an important cause of mortality and morbidity in preterm infants and inflammation plays an important role in its pathogenesis. The use of inhaled corticosteroids may modulate the inflammatory process without concomitant high systemic steroid concentrations and less risk of adverse effects. ⋯ This review found no evidence that early inhaled steroids confer important advantages over systemic steroids in the management of ventilator dependent preterm infants. Neither inhaled steroids nor systemic steroids can be recommended as a part of standard practice for ventilated preterm infants. Because they might have fewer adverse effects than systemic steroids, further randomised controlled trials of inhaled steroids are needed that address risk/benefit ratio of different delivery techniques, dosing schedules and long-term effects, with particular attention to neurodevelopmental outcome.

Review Meta AnalysisIntracutaneous or subcutaneous sterile water injection compared with blinded controls for pain management in labour.
Intracutaneous or subcutaneous injection of sterile water is rapidly gaining popularity as a method of pain relief in labour and it is therefore essential that it is properly evaluated. Adequate analgesia in labour is important to women worldwide. Sterile water injection is inexpensive, requires basic equipment, and appears to have few side effects. It is purported to work for labour pain. ⋯ The outcomes reported severely limit conclusions for clinical practice. We found little robust evidence that sterile water is effective for low back or any other labour pain. Neither did we find any difference in delivery or other maternal or fetal outcomes. Further large, methodologically rigorous studies are required to determine the efficacy of sterile water to relieve pain in labour.

Review Meta AnalysisInterventions to improve the use of systematic reviews in decision-making by health system managers, policy makers and clinicians.
Systematic reviews provide a transparent and robust summary of existing research. However, health system managers, national and local policy makers and healthcare professionals can face several obstacles when attempting to utilise this evidence. These include constraints operating within the health system, dealing with a large volume of research evidence and difficulties in adapting evidence from systematic reviews so that it is locally relevant. In an attempt to increase the use of systematic review evidence in decision-making a number of interventions have been developed. These include summaries of systematic review evidence that are designed to improve the accessibility of the findings of systematic reviews (often referred to as information products) and changes to organisational structures, such as employing specialist groups to synthesise the evidence to inform local decision-making. ⋯ Mass mailing a printed bulletin which summarises systematic review evidence may improve evidence-based practice when there is a single clear message, if the change is relatively simple to accomplish, and there is a growing awareness by users of the evidence that a change in practice is required. If the intention is to develop awareness and knowledge of systematic review evidence, and the skills for implementing this evidence, a multifaceted intervention that addresses each of these aims may be required, though there is insufficient evidence to support this approach.
