Comparative Study Clinical Trial Controlled Clinical Trial
Povidone iodine plus neosporin in superficial burns--a continuing study.
A total of 1053 patients with superficial burn injury were treated with povidone iodine plus neosporin (PVP + N) and the results after treatment were compared with those obtained after treating 1089 patients with silver sulphadiazine (SSD). Qualitative analysis showed Staphylococcus aureus and Pseudomonas spp. to be the most common infecting organisms. ⋯ Similarly, healing times were also better with PVP + N, with a maximum number of patients having healed within 15 days (P < 0.001). However, the mortality rates were not much different between the two groups.

Comparative Study Clinical Trial Controlled Clinical Trial
Characterization of T-cell subsets infiltrating post-burn hypertrophic scar tissues.
In this study, skin-infiltrating cells were characterized in both the active and remission phases of post-burn hypertrophic scar biopsies. Immunohistochemistry examination of active phase samples showed an abundant presence of Langerhans cells, T cells, macrophages, a low presence of natural killer cells and the lack of B lymphocytes. In active hypertrophic scars T lymphocytes infiltrate deep into the superficial dermis and are also observed in the epidermis: CD3+ cells were present at about 222 +/- 107 per 0.25 mm2. ⋯ Central to the immune hypothesis of hypertrophic scars is that some of the T-cell lymphokines act on keratinocytes, fibroblasts and other cell types to induce changes characteristic of these scars. The presence and close proximity of activated T lymphocytes and antigen-presenting cells of various phenotypes in both the epidermis and dermis of hypertrophic tissues provides strong circumstantial evidence of a local immune response. However, the manner in which T cells achieve and maintain their activated state in hypertrophic tissues is not yet known, and both antigen-dependent and independent mechanisms may contribute.

Research on the psychological impact of burn injuries has concentrated on major burns, while small burns have been largely neglected. In a prospective study, 45 patients with burn injuries ranging from 1 per cent or less up to 40 per cent total body surface area were assessed using semi-structured interviews within 2 weeks of sustaining the burn, and followed-up at approximately 3 months postburn to investigate the prevalence of mental health problems. ⋯ Patients with small burn injuries of 1 per cent or less also experienced clinically significant levels of psychological difficulties postburn. The implications for the identification of patients at risk of future psychological morbidity are discussed.

Despite the widespread use of liquid nitrogen, there are few reports of injuries caused by the use of this substance. We report a case in which a severe liquid nitrogen burn, requiring digital amputation, occurred despite the wearing of protective gloves. This case illustrates the potential dangers of working with liquid nitrogen, and raises questions as to whether adequate precautions are being taken to prevent such injuries.

Neuropathy in burn patients is frequently overlooked. This study aimed at looking for neuropathies among burn patients. It included 55 burn patients, whether symptomatic or asymptomatic, with variable depths of burn at different stages. ⋯ All the entrapment neuropathy developed after wound healing. Age above 20 years, electric burns burns involving full thickness of the skin and a surface area of more than 20 per cent were associated with a significantly higher prevalence of neuropathy. Other parameters were not found to be significant in the development of neuropathy.
