ReviewArthroscopic surgery for degenerative knee disease (osteoarthritis including degenerative meniscal tears).
Arthroscopic knee surgery remains a common treatment for symptomatic knee osteoarthritis, including for degenerative meniscal tears, despite guidelines strongly recommending against its use. This Cochrane Review is an update of a non-Cochrane systematic review published in 2017. ⋯ Arthroscopic surgery provides little or no clinically important benefit in pain or function, probably does not provide clinically important benefits in knee-specific quality of life, and may not improve treatment success compared with a placebo procedure. It may lead to little or no difference, or a slight increase, in serious and total adverse events compared to control, but the evidence is of low certainty. Whether or not arthroscopic surgery results in slightly more subsequent knee surgery (replacement or osteotomy) compared to control remains unresolved.

Gabapentinoids are increasingly prescribed to manage chronic noncancer pain (CNCP) in older adults. When used concurrently with opioids, gabapentinoids may potentiate central nervous system (CNS) depression and increase the risks for fall. We aimed to investigate whether concurrent use of gabapentinoids with opioids compared with use of opioids alone is associated with an increased risk of fall-related injury among older adults with CNCP. ⋯ In this sample of older Medicare beneficiaries with CNCP, initiating gabapentinoids and opioids simultaneously compared with initiating opioids only was not significantly associated with risk for fall-related injury. However, addition of gabapentinoids to an existing opioid regimen was associated with increased risks for fall. Mechanisms for the observed excess risk, whether pharmacological or because of channeling of combination therapy to high-risk patients, require further investigation. Clinicians should consider the risk-benefit of combination therapy when prescribing gabapentinoids concurrently with opioids.

In addition to the well-known clinical early symptoms of hantavirus disease (fever, flank and abdominal pain as well as arthralgia), unusual neurological changes in the context of infection come into focus. The spectrum of neurological symptoms ranges from transient myopia to severe pareses in the context of Guillain-Barré syndrome. In endemic areas, rapid IgM tests for initial assessment are of certain value for differential diagnosis. ⋯ A new systematic review could not confirm a human-to-human transmission previously postulated for South American hantaviruses. While all known human pathogenic hantaviruses are transmitted by rodents, other hantaviruses have been recently detected in shrews, moles, and bats. The clinical significance of these new viruses is quite unclear as yet.

Randomized Controlled Trial
Efficacy and Safety of a New Sustained-released Pregabalin Formulation Compared with Immediate-release Pregabalin in Patients with Peripheral Neuropathic Pain: A Randomized Non-inferiority Phase 3 Trial.
This study investigated whether a new sustained-release (SR) pregabalin formulation is noninferior to immediate-release (IR) pregabalin in alleviating peripheral neuropathic pain in Korean patients. ⋯ The results demonstrate that the new once-daily SR pregabalin formulation is noninferior to twice-daily IR pregabalin in reducing peripheral neuropathic pain and is well tolerated in Korean patients with diabetic peripheral neuropathy or postherpetic neuralgia after 12 weeks of treatment.
