ReviewTropical dermatology: Venomous arthropods and human skin: Part II. Diplopoda, Chilopoda, and Arachnida.
Members of arthropod classes Chilopoda (centipedes), Diplopoda (millipedes), and Arachnida (spiders and scorpions) cause tissue injury via bites, stings, and/or a release of toxins. A few members of the Acari subclass of Arachnida (mites and ticks) can transmit a variety of infectious diseases, but this review will cover the noninfectious manifestations of these vectors. Dermatologists should be familiar with the injuries caused by these arthropods in order to initiate proper treatment and recommend effective preventative measures.

Recommendations and current practices for the reconstitution and storage of botulinum toxin type A.
Current guidelines from the Centers for Disease Control and Prevention (CDC) regarding the reconstitution and storage of botulinum toxin type A (BT-A) differ from those of the Centers for Medicare and Medicaid Services and current clinical practice. CDC guidelines require single-patient use of BT-A vials. Strict adherence to these guidelines creates waste and a significant financial impediment, and does not confer increased protection from infection, assuming standard safe injection practices are followed. ⋯ A single vial of BT-A can be safely administered to multiple patients, assuming standard safe injection techniques are followed. After reconstitution, Our data suggest that BT-A can be stored beyond the recommended time period of 4 hours.
