  • Purpose: Due to rapid changes in the industrial structure in last decade, the wider various types of chemical agents were introduced. Burn surgeons should be well-informed with rapid changes of chemical burns. We present the recent incidence trends of causing agents of chemical burns. Methods: From 2010 to 2019, 92 chemical burn victims were included in this study. A retrospective study was made about the type, distribution and incidence of the causing agents of chemical burns. Initial treatments of most chemical burn wounds are copious saline irrigation by tap water, except hydrofluoric acid burn cases managed by 10% calcium gluconate injection. In alkali chemical burns on extremity, if thin eschars appear in postburn 2~3 days, acute early surgical escharectomy and split thickness skin graft were done. Results: More than 9 types of major chemicals causing chemical burns were surveyed, and the most common causing agent of chemical burns was Hydrofluoric acid (23.9%) followed by Acetic acid (19.6%) and Sodium hydroxide (8.7%). Conclusion: From 2010 to 2019, changes in the causing agent of chemical burns are that the types of major causing agents of chemical burns have increased and the distribution and incidence of causing agents have changed compared to previous reports. According to this study, more than 9 types of major chemicals causing chemical burns were surveyed, and the most common causing agent of chemical burns was Hydrofluoric acid (23.9%) followed by Acetic acid, Sodium hydroxide.

  • In the extremity surgery, pneumatic tourniquet and povidone-iodine solution are commonly used to provide an aseptic, bloodless field, and their complication rate has remained low. However, chemical burn under tourniquet has been rarely reported. Patients sustained burn injuries over the dependent, weight-bearing regions such as posterior neck, back, buttocks and posterior thighs. This rare adverse complication occurred in a 22-year-old man who underwent modified Brostrom operation with arthroscopic os trigonum excision. 10% povidone-iodine was used as topical antiseptic, and full thickness burn occurred underneath the area of tourniquet application. Main causes of povidone-iodine related chemical burn are considered maceration, irritation of the skin, long term use of the tourniquet and pressure. To reduce the complications like chemical burn, awareness of the risk and the possible pathogenesis as well as the preventive measures is important in surgical practice.

  • TCA is widely used in cosmetic treatments such as chemical peels, tattoo removal, and also in gynecological procedures for managing cervical intraepithelial neoplasia. However, storage of high concentration of TCA in a gynecology office is a potential hazard, as it may accidentally cause severe chemical burns. We report a case of deep dermal TCA chemical burn on genital area, which occured accidentally and resulted from misuse of high concentration (90%) of TCA coated vaginal gauze packing dressing during gynecological procedures.

  • This study is to investigate changes of pore structure with different burn-off degree of steam activated carbons manufactured from domestic anthracite. The activated carbons were characterized by adsorption of nitrogen at 77 K. Steam activation substantially enhanced the porosity of the activated carbons. Burn-off increased linearly according to increasing activation time, and total pore volume and BET surface area increased with burn-off. Activation at $800^{\circ}C$ increased more micropore volume than that at $950^{\circ}C$. Activated carbons manufactured at high temperature had less microporosity than that at lower temperature, but had more developed macroporosity. The steam activation produced an enlargement of pore below $100{\AA}$ diameter in the activated carbons. Furthermore, the porosity in the $6{\sim}40{\AA}$ pore diameters range increased considerably with the degree of burn-off.

  • The theory previously proposed to simulate hole depth in the weak burn intensity limit is extended to examine the hole depth at arbitrary burn intensity using 3-level system model. The hole spectrum simulated using constant fluence gives different hole depth for strong burn intensity while it gives same hole depth for weak burn intensity region. The calculated hole growth curves are compared with published experimental data for oxazine720 in glycerol and tetracene in MTHF glass.

  • Purpose: Chemical burn accounts for a small proportion of burns in burn patient population. However, chemical injuries own importance to their deep tissue destruction which continues long after the initial exposure. $YUHANROX^{(R)}$ is a domestic bleach which has been widely used in Korea. Chemical burn by the domestic bleach is an unusual case. Methods: A 70 yrs old female soiled with stool, her husband wiped the mess with $YUHANROX^{(R)}$. Skin edema, erythematous lesion was developed the second day, and she was admitted to our hospital via emergency department. Results: Complete epithelization was done after 3 times STSG but, severe scar was formed. Conclusion: We report this case to warn about the dangers of domestic bleaches chemical substances and to emphasize that they should be used with caution. Public relation of the primary care of the chemical burn injury is needed.

  • Hydrofluoric acid is a colorless gas or fuming liquid with a strong, irritating odor. Hydrofluoric acid burns are uncommon; however, if severe burn occur, they caused death from systemic effects, such as fatal cardiac arrthmia. We experienced two cases of hydrofluoric acid chemical burns on digits. These patients had typical clinical features of hydrofluoric acid chemical burns, such as pulsating pain at the burn site, as well as ischemic and necrotic skin changes. The hydrofluoric acid chemical burn was confirmed by a history of exposure. Subsequently, we made a calcium gluconate gel by mixing 20% calcium gluconate, an antagonist against hydrofluoric acid, with lubricant, and we injected 10% calcium gluconate subcutaneously when they complained of pain rated at higher than 5 on the pain scale. Simultaneously, we monitored the patients' electrocardiographs and checked their serum total calcium, ionized calcium, and magnesium levels serially. Clinical presentations and the emergency management of hydrofluoric acid chemical burns were reviewed along with the current literature. These patients were discharged without any significant complications.

  • Purpose: Hydrofluoric acid(HF) is one of the most dangerous mineral acids with the dissociated fluoride ions. The initial corrosive burn is caused by free hydrogen ion, and the second and more severe burn is caused by penetration of fluoride ions into subcutaneous tissues. Silver is a cation producing dressing, an effective antimicrobial agent, but older silver-containing formulations are rapidly inactivated by wound environment, requiring frequent replenishment. But, $Acticoat^{(R)}$ is a relatively new form of silver dressing which helps avoid the problems of earlier agents. The aim of this study is to evaluate effects of $Acticoat^{(R)}$, silver-containing dressing on the treatment for HF injury wound. Methods: From september 2006 to september 2007, the study was carried out with 10 patients who had HF partial thickness burns. $Acticoat^{(R)}$ dressing and 10% calcium gluconate wet gauze dressings in 10 cases. As a principle, in the emergency treatment, partial or complete removal of the nail and early bullectomy along with copious washing with normal saline was done, depending on the degree of HF invasion of the wound. Wound was dressed with $Acticoat^{(R)}$ and 10% calcium gluconate solution. The effect of dressing was investgated by serial bacterial culture and wound exudates assessment. Results: We therefore reviewed 10 cases of HF-induced chemical burns and treatment principle. The 10 cases who came to the hospital nearly immediately after the injury healed completely without sequelae. Conclusion: As the industrial sector develops, the use of HF is increasing more and more, leading to increased incidences of HF-induced chemical burns. The education of patients regarding this subject should be empathized accordingly. In conclusion, $Acticoat^{(R)}$ dressing is a better choice for HF partial thickness burn injuries because of shorter healing time, less pain and more comfortable dressing.

  • When we use the total-etch dentin adhesive system for composite resin restorations, gel or liquid acid etchant such as 37% phosphoric acid is commonly used. Thirty seven percentage phosphoric acid is very powerful erosive agent, and can cause severe harmful effects when it contacts with an oral mucosa and facial skin. This case describes iatrogenic chemical burn on facial skin caused by phosphoric acid which was happened during composite resin restorative procedure. Chemical burn by acid etchant can be evoked by careless handling of remnant and syringe. In order to prevent these iatrogenic injuries, we should check the complete removal of the etching agent both in intra and extra-oral environments after etching and rinsing procedure and it is necessary to use of the rubber dam or isolation instruments. If accidental burn were occurred. immediate wash with copious water. And bring the patient to the dermatologist as soon as possible.

  • Dichloromethane is widely used as a solvent in paint removers. Unlike inhalation injury, contact injury caused by dichloromethane is not well known. Two patients who had undergone skin grafting to treat chemical burn of the hand caused by dichloromethane exposure were evaluated, and a literature review was done. Two healthy men aged 37 and 40 years visited our hospital with chief complaints of pain on the hands due to dichloromethane exposure. The patients had not worn protective clothing. Multiple bullae were initially noted. On the next day, fluctuation in bullae and purulent discharge were observed, and central eschar change was noted. On the 18th day after the burn, escharectomy and full-thickness skin graft were performed. Therefore, workers who use dichloromethane should wear protective clothing at workplaces. If exposed to the chemical, the worker should be instructed to do a quick wash and visit the hospital.
