Review Meta AnalysisSweet-tasting solutions for needle-related procedural pain in infants one month to one year of age.
Administration of oral sucrose or glucose with and without non-nutritive sucking is frequently used as a non-pharmacological intervention for needle-related procedural pain relief in infants. ⋯ There is insufficient evidence to confidently judge the effectiveness of sweet-tasting solutions in reducing needle-related pain in infants (one month to 12 months of age). The treatments do, however, appear promising. Data from a series of individual trials are promising, as are the results from a subset meta-analysis of studies measuring duration of crying. Further well controlled RCTs are warranted in this population to determine the optimal concentration, volume, method of administration, and possible adverse effects.

Review Meta AnalysisBisphosphonates in multiple myeloma: a network meta-analysis.
Bisphosphonates are specific inhibitors of osteoclastic activity and used in the treatment of patients with multiple myeloma (MM). While bisphosphonates are shown to be effective in reducing vertebral fractures and pain, their role in improving overall survival (OS) remains unclear. This is an update of a Cochrane review first published in 2002 and previously updated in 2010. ⋯ Use of bisphosphonates in patients with MM reduces pathological vertebral fractures, SREs and pain. Assuming a baseline risk of 20% to 50% for vertebral fracture without treatment, between 8 and 20 MM patients should be treated to prevent vertebral fracture(s) in one patient. Assuming a baseline risk of 31% to 76% for pain amelioration without treatment, between 5 and 13 MM patients should be treated to reduce pain in one patient. With a baseline risk of 35% to 86% for SREs without treatment, between 6 and 15 MM patients should be treated to prevent SRE(s) in one patient. Overall, there were no significant adverse effects associated with the administration of bisphosphonates identified in the included RCTs. We found no evidence of superiority of any specific aminobisphosphonate (zoledronate, pamidronate or ibandronate) or nonaminobisphosphonate (etidronate or clodronate) for any outcome. However, zoledronate appears to be superior to placebo and etidronate in improving OS.

Review Meta AnalysisModifications of the Epley (canalith repositioning) manoeuvre for posterior canal benign paroxysmal positional vertigo (BPPV).
Benign paroxsymal positional vertigo (BPPV) is a syndrome characterised by short-lived episodes of vertigo associated with rapid changes in head position. It is a common cause of vertigo presenting to primary care and specialist otolaryngology (ENT) clinics. BPPV of the posterior canal is a specific type of BPPV for which the Epley (canalith repositioning) manoeuvre is a verified treatment. A range of modifications of the Epley manoeuvre are used in clinical practice, including post-Epley vestibular exercises and post-Epley postural restrictions. ⋯ There is evidence supporting a statistically significant effect of post-Epley postural restrictions in comparison to the Epley manoeuvre alone. However, it important to note that this statistically significant effect only highlights a small improvement in treatment efficacy. An Epley manoeuvre alone is effective in just under 80% of patients with typical BPPV. The additional intervention of postural restrictions has a number needed to treat (NNT) of 10. The addition of postural restrictions does not expose the majority of patients to risk of harm, does not pose a major inconvenience, and can be routinely discussed and advised. Specific patients who experience discomfort due to wearing a cervical collar and inconvenience in sleeping upright may be treated with the Epley manoeuvre alone and still expect to be cured in most instances.There is insufficient evidence to support the routine application of mastoid oscillation during the Epley manoeuvre, or additional steps in an 'augmented' Epley manoeuvre. Neither treatment is associated with adverse outcomes. Further studies should employ a rigorous randomisation technique, blinded outcome assessment, a post-treatment Dix-Hallpike test as an outcome measure and longer-term follow-up of patients.

Review Meta AnalysisExpectant care versus surgical treatment for miscarriage.
Miscarriage is a common complication of early pregnancy that can have both medical and psychological consequences such as depression and anxiety. The need for routine surgical evacuation with miscarriage has been questioned because of potential complications such as cervical trauma, uterine perforation, hemorrhage, or infection. ⋯ Expectant management led to a higher risk of incomplete miscarriage, need for unplanned (or additional) surgical emptying of the uterus, bleeding and need for transfusion. Risk of infection and psychological outcomes were similar for both groups. Costs were lower for expectant management. Given the lack of clear superiority of either approach, the woman's preference should be important in decision making. Pharmacological ('medical') management has added choices for women and their clinicians and has been examined in other reviews.

Review Meta AnalysisCaffeine as an analgesic adjuvant for acute pain in adults.
Caffeine has been added to common analgesics such as paracetamol, ibuprofen, and aspirin, in the belief that it enhances analgesic efficacy. Evidence to support this belief is limited and often based on invalid comparisons. ⋯ The addition of caffeine (≥ 100 mg) to a standard dose of commonly used analgesics provides a small but important increase in the proportion of participants who experience a good level of pain relief.
