Four patients with oral chronic graft-versus-host disease pain were treated with loperamide oral-rinse solution. Two-week continued use of the drug solution improved not only the pain scores but also the pain-causing disabilities associated with eating, drinking and sleeping, with no noticeable side effects. Current results suggest that the mu-opioid agonist, loperamide, has a potential analgesic effect that could be clinically used as a peripheral analgesic agent for stomatits pain. However, these observations will need to be further confirmed in a randomized-controlled trial.

Closed multiple metacarpal fractures are uncommon. They are usually associated with significant soft tissue swelling. Early stable fixation and functional rehabilitation optimises outcome. We present a review of 19 patients with 43 metacarpal fractures treated by early open reduction and internal fixation with 2 mm plates. Eighteen patients recovered a full range of motion, while one patient was lost to follow-up. Implant removal on account of extensor irritation was required in only two metacarpals in two patients. Plating of multiple closed metacarpal fractures is a safe, reliable and consistently reproducible treatment method.

We present an alternative interpretation of the holographic phase dislocation loops revealed by Shindo et al. [J. Electron Microsc. 56(1): 1–5 (2007)] around a charged sample. Our interpretation does not involve the motion of secondary electrons around a charged object. It relates, instead, to fluctuating charges on the sample and to the resulting Moiré-type patterns in the hologram.
