Introduction: Burn scars cause cosmetic disfigurement and psychosocial distress. We present two Fitzpatrick phototype (FP) III patients with burn scars successfully treated with combination pulsed dye laser (PDL) and non-ablative fractional lasers (NAFL). Case 1: A 30-year-old, FP III woman with a history of a second-degree burn injury to the bilateral arms and legs affecting 30% body surface area (BSA) presented for cosmetic treatment. The patient received three treatments with 595 nm PDL (7 mm, 8 J, 6 ms), six with the 1550 nm erbium:glass laser (30 mJ, 14% density, 4–8 passes) and five with the 1927 nm thulium laser (10 mJ, 30% density, 4–8 passes). Treated burn scars improved significantly in thickness, texture and colour. Case 2: A 33-year-old, FP III man with a history of a second-degree burn injury of the left neck and arm affecting 7% BSA presented for cosmetic treatment. The patient received two treatments with 595 nm PDL (5 mm, 7.5 J, 6 ms), four with the 1550 nm erbium:glass laser (30 mJ, 14% density, 4–8 passes) and two with the 1927 nm thulium laser (10 mJ, 30% density, 4–8 passes). The burn scars became thinner, smoother and more normal in pigmentation and appearance. Discussion: Our patients’ burn scars were treated with a combination of PDL and NAFL (two wavelengths). The PDL targets scar hypervascularity, the 1550 nm erbium:glass stimulates collagen remodelling and the 1927 nm thulium targets epidermal processes, particularly hyperpigmentation. This combination addresses scar thickness, texture and colour with a low side effect profile and is particularly advantageous in patients at higher risk of post-procedure hyperpigmentation. Conclusion: Our cases suggest the combination of 595nm PDL plus NAFL 1550 nm erbium:glass/1927 nm thulium device is effective and well-tolerated for burn scar treatment in skin of colour.

An unusual burn case caused by hot wormwood leaf water was discussed. A 29-year-old woman sustained a 7% second-degree burn on both buttocks and left thigh. This case report highlights a rare cause of a chemical burn that may become more common with increasing use of this Chinese traditional medicine. The prevention measures of this burn injury were also presented.

This paper presents a model for heat and moisture transfer through firefighters’ protective clothing (FPC) during radiation exposure. The model, which accounts for air gaps in the FPC as well as heat transfer through human skin, investigates the effect of different initial moisture contents on the thermal insulation performance of FPC. Temperature, water vapor density, and the volume fraction of liquid water profiles were monitored during the simulation, and the heat quantity absorbed by water evaporation was calculated. Then the maximum durations of heat before the wearer acquires first- and second-degree burns were calculated based on the bioheat transfer equation and the Henriques equation. The results show that both the moisture weight in each layer and the total moisture weight increase linearly within a given environmental humidity level. The initial moisture content in FPC samples significantly influenced the maximum water vapor density. The first- and second-degree burn injury time increase 16 sec and 18 sec when the RH increases from 0% to 90%. The total quantity of heat accounted for by water evaporation was about 10% when the relative humidity (RH) is 80%. Finally, a linear relationship was identified between initial moisture content and the human skin burn injury time before suffering first- and second-degree burn injuries.

Burn injury represents a complex clinical entity with significant associated morbidity and remains the second leading cause of trauma-related death. An understanding of the local and systemic pathophysiology of burns has led to significant improvements in mortality. Thermal insult results in coagulative necrosis of the skin and the depth or degree of injury is classified according to the skin layers involved. First-degree burns involve only epidermis and heal quickly with no scar. Second-degree burns are further classified into superficial partial thickness or deep partial thickness depending on the level of dermal involvement. Damage in a third-degree burn extends to subcutaneous fat. There is a substantial hypermetabolic response to severe burn, resulting in significant catabolism and untoward effects on the immune, gastrointestinal, and renal systems. Accurate assessment of the extent of burn injury is critical for prognosis and initiation of resuscitation. Burn size, measured in total body surface area, can be quickly estimated using the rule of nines or palmar method. A more detailed sizing system is recommended once the patient has been triaged. Appropriate diagnosis of burn depth will be important for later management. First-degree burns are erythematous and painful, like a sunburn; third-degree burns are leathery and insensate. Differentiating between second-degree burn types remains difficult. There are a number of formalized criteria during assessment that should prompt transfer to a burn centre.
