Burns patients were assessed 12 months following their injury to determine the factors that predict development of post-traumatic stress disorder (PTSD). Among 35 patients, 31 per cent suffered PTSD, 29 per cent suffered subclinical PTSD reactions and 40 per cent displayed no PTSD symptoms. ⋯ The results indicate that postinjury adjustment factors are critical determinants of PTSD development following burns. Implications for therapeutic interventions are discussed.

Exposure of the skin to nitrous oxide, a liquified gas stored under pressure in a cylinder, can occur in anaesthesiologists and in those involved in recreational misuse of the gas. A case is reported of a man who presented to the emergency department after sniffing nitrous oxide and sustaining frostbite injury to his left cheek. Conservative management of this injury allowed spontaneous separation of the necrotic tissue and healing of the granulating wound by contraction.

Magnetic resonance imaging: a new diagnostic aid in the care of high-voltage electrical burns.
Magnetic resonance imaging (MRI) can detect and delineate alterations in the hydration properties of tissues such as oedema and necrosis. The distinction between living tissue oedema and frank necrosis is also possible with MRI, by use of a spin-echo (SE) sequence and a fast spin-echo (FSE) sequence with a 1.5 T imager. With this background, the aim of this study was to examine the ability of MRI for early detection of concealed tissue injuries caused by high-voltage electrical burns, an entity not previously explored. ⋯ The T2-weighted images provided substantial information about the localization and amount of muscle necrosis, thus enabling increased surgical precision in the treatment of these high-voltage injury victims. FSE sequences produce T2-weighted images with increased speed of acquisition and/or increased image resolution compared to conventional SE sequence. Two illustrative examples are provided.

A case of a chemical burn following cutaneous exposure to vinylpyridine is presented. This unusual injury was distinguished by the delay in onset of pain and erythema, followed by gradual resolution leaving patchy skin discolouration. The properties of vinylpyridine are outlined. This case illustrates the dangers of long-term chemical storage and the importance of proper disposal.
