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.

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.

The burn center in our hospital is a national and regional (Southeast Asia) center. Of all admissions, 10% are related to blast explosions, and 8% due to chemical burns. In the acute burn management protocol of Singapore General Hospital, early surgical debridement is advocated for all acute partial-thickness burns. The aim of early surgical debridement is to remove all debris and unhealthy tissue, preventing wound infection and thereby expediting wound healing. In chemical burns, there can be stubborn eschars that are resistant to traditional debridement. We would like to present a novel technique using the diathermy scratch pad as a cheap and efficient tool for the dual purpose of surgical debridement and dermabrasion.

Purpose: Hydrofluoric acid(HF) is one of the most dangerous mineral acids with dissociated fluoride ions. As hydrofluoric acid is present in various household products(such as rust removers), a large population of industrials is at the risk of HF exposure. It is a very strong organic acid, used widely in glass etching, metal washing, and in the semiconductor industry. Even when using adequate safety measures, lack of care on the user's part results in chemical burn by HF. Symptoms caused by HF-induced chemical burns shows delayed manifestations resulting in a loss of proper treatment opportunities. We therefore reviewed 20 cases of HF-induced chemical burns and treatment principle. Methods: The objects of this study were 19 male patients and 1 female treated from March 2004 to March 2006. There were 19 cases of injury on digits and 1 on the wrist area. There were 15 cases of immediate treatment after sustaining HF-induced burns, and 5 cases of delayed treatment. As a principle, in the emergency treatment, partial or complete removal of the nail along with copious washing with normal saline was done, depending on the degree of HF invasion of the distal digital extremities. Results: The 15 cases who came to the hospital immediately after the injury were healed completely without sequelae, and those who delayed their treatment needed secondary surgical measures, due to the severity of inflammation and necrosis of the digital tissues. Conclusion: As the industrial sector develops, the use of HF is increasing more and more, leading to increase in incidences of HF-induced chemical burns. When treating chemical burns caused by HF, washing by copious amounts of normal saline, along with early removal of the nails, rather than calcium gluconate, seems to be a available method for preserving the shape and function of the digits and the nail. The education of patients regarding this subject should be empathized accordingly.

Oral mucosal burns can occur after contact with various chemical agents, and commonly manifest as areas of mucosal sloughing and ulceration. Policresulen (Albothyl, Celltrion Pharm Inc.) is an over-the-counter topical antiseptic that is frequently used to treat stomatitis. Policresulen solution is highly acidic, with an approximate pH of 0.6; it can thus cause mucosal injury when improperly applied in the oral cavity. Here, we present a rare case of an oral mucosal burn resulting from incorrect self-administration of policresulen and emphasize the importance of increasing understanding of this adverse drug event among consumers and health professionals.

A novel gene, designated mgt-6, containing four splicing variants, was isolated from a gene trap clone library of C3H/10T1/2 cells transfected with retroviral promoterless gene-trap vector, ROSAFARY. The transcript variants were differentially expressed in murine tissues and cell lines and differentially responded to diverse stimuli including TGF-${\beta}1$ and mitogen-activated protein kinase (MAPK) inhibitors. The mgt-6 gene encoded a protein of 37 or 11 amino acid residuals with cytoplasmic distribution. However, when C3H/10T1/2 cells were treated with 5-azacytidine, the protein translocated into cell nucleus as indicated by fused LacZ or C-terminally tagged EGFP. Our preliminary results suggest that further study on the role of mgt-6 gene in cell transformation and differentiation may be of significance.

Purpose: The purpose of this study was to examine the burn characteristics of female patients hospitalized in a burn center. Methods: This is a retrospective descriptive study. The subjects were 222 female patients aged over 19 years old having burn injuries from work sites between January 1, 2012 and December 31, 2014. Data were collected using electronic medical records about the burn-related characteristics. The data were analyzed descriptively. Results: Many of the subjects were in their forties and fifties. Most subjects showed burns with an area of less than 10% of the body surface with a severity of second degree. Scalding burns were the most frequent. Contact burns were usually of third-degree severity and occurred on hands and wrists. Flame burns affected the largest body surface area and frequently occurred on the face and mainly caused by explosion of a stove or kitchen gas. Chemical burns frequently occurred on the lower limbs. Conclusion: Female workers are exposed to the hazards of burn injuries in industrial accidents. Types of burn differ depending on the workplace conditions. Therefore, preventative measures for burn injuries should be established in accordance with the characteristics of each industry to which female workers belong.

Many commonly used household chemicals and medical eye drops look alike, resulting in a worldwide increase in incidences of accidents caused by confusion between similar-looking agents. In this case report, we present two patients who visited the emergency department following inadvertent instillation of tinea pedis treatment solution instead of eye drops. Both patients developed corneal chemical burns following the accidental application. Notably, the visual acuity and symptoms eventually recovered for both patients after hospitalization. However, complete recovery occurred only after several weeks. Both patients were relatively old and had been prescribed eye drops after previous ophthalmic surgery. Since the eye is a sensory organ that receives visual information, ocular injuries significantly affect the quality of life and social functioning of the patient. Incidences of accidental misidentification of eye drops are steadily increasing in South Korea; unfortunately, regulatory policies are unavailable to avoid such hazards. Therefore, physicians should be mindful of the potential risks associated with misidentification of everyday household products and must spend time educating patients when prescribing eye drops. Policy regulations are warranted for products with containers that resemble eye drop bottles. Such items need to be clearly labeled with additional warnings to prevent misidentification and accidental ocular instillation.

The more occurred during winter (29.7%). SB had mean 3.9% total body surface area (TBSA). The 251 (82.3%) had superficial burns by spillage of hot water/food on lower limbs (45.6%), feet (33.8%) in summer (34.8%), treated with simple dressing (92.8%). Morbidity rate was 5.6%; post traumatic stress disease (PTSD) (0.7%). FB had large wound (9.3% TBSA). The 209 (64.3%) had superficial burns by ignition to flammable oils (31.7%) and bomb powders (29.2%) on head/neck (60.3%), hands (58.6%) in summer (31.7%), autumn (30.2%). They underwent simple dressing (83.4%) and skin graft (16.0%). Morbidity rate was 18.8%; PTSD (10.5%), inhalation injuries (4.0%), corneal injury (3.7%), amputations (0.9%), and mortality rate (1.2%). CB had small (1.1% TBSA), deep burns (78.5%) by hotpack (80.4%) on lower limbs (80.4%). The more (59.8%) underwent skin graft. EB had 6.8% TBSA. The 29 (64.4%) had superficial burns by touching to high tension cable (71.1%) on hand (71.1%), upper limbs (24.4%) in autumn (46.8%). They underwent simple dressing (71.1%) and skin graft (24.4%). They showed high morbidity rate (40.0%); loss of consciousness (13.3%), nerve injuries (11.1%), neuropathy (8.9%), amputations (2.2%), and mortality rate (2.2%). Conclusions: The cook should wear apron over the boots during work. The lighter or smoking should be strictly prohibited during work with flammable liquids or bomb powders. Don't directly apply hotpack to skin for a long time. Use insulating glove during electric work. Keep to the basic can prevent severe injury and proper education is important.
