Background: Botulinum toxin (BoNT) has been in use since the late 1970s, and over the last 20 years, its use has been extended to new indications in various areas of medicine. During these years of clinical use, some of the initial ideas have changed, and others have remained stable along with increasing experience with and knowledge about BoNTs.

Objective: To review the literature and prescribing information on all of the available products and to update the concept of handling toxins (preparations, reconstitution, storage, sterility, and dilution).

Methods: A review (not Cochrane type analysis) of the medical literature based on relevant databases (MEDLINE, PubMed, Cochrane Library, specialist textbooks, and manufacturer information) was performed.

Conclusions: Many of the precautions around BoNT use, often recommended by the manufacturers, are described in the clinical literature as too restrictive. The literature suggests that toxins may be sturdier and more-resistant to degradation than previously understood.

Background: While previous reports characterised global and regional variations in RSV seasonality, less is known about local variations in RSV seasonal characteristics. This study aimed to understand the local-level variations in RSV seasonality and to explore the role of geographical, meteorological, and socio-demographic factors in explaining these variations.

Methods: We conducted a systematic literature review to identify published studies reporting data on local-level RSV season onset, offset, or duration for at least two local sites.

Background: Pain is a major challenge for patients with rheumatoid arthritis (RA), with many people suffering chronic pain. Current RA management guidelines focus on assessing and reducing disease activity using disease-modifying anti-rheumatic drugs (DMARDs). Consequently, pain care is often suboptimal, with growing evidence that analgesics are widely prescribed to patients with RA, despite potential toxicities and limited evidence for efficacy.
