Work-related burns: a 6-year retrospective study

During the 6 years from July 1984 to May 1990, 193 patients (30.2 per cent of all patients) were admitted to our regional adult burn centre, for treatment of work-related burn injuries. The median age of patients was 32.5 years (range 18-64 per cent), and 94 per cent were males. Fifty-nine per cent of the patients came from metropolitan Toronto, and 40 per cent from rural Ontario. Most of the patients (97.3 per cent) were referred to the burn centre within 24 h of their injury. The most common aetiology was electrical injury (29.5 per cent), followed by flame (24.4 per cent), contact (10.4 per cent), flash (9.8 per cent), tar and asphalt (9.3 per cent), scald (7.8 per cent), chemical (5.1 per cent), steam (4.7 per cent) and grease (1 per cent). Within the electrical burn group, about one-half were flash burns, one-quarter were clothing fire injuries, and one-quarter were contact injuries. These occupational burns tended to be extensive injuries. The median body surface area (BSA) was 16.5 per cent, with a median full thickness (FT) component of 5.0 per cent. The average length of stay was 20.0 days. Inhalation injury requiring intubation occurred in 14.8 per cent of patients. Sepsis--confirmed by positive blood cultures--developed in 14 per cent of the patients, at an average time of 8.8 days postburn. Staphylococcus aureus was the commonest organism isolated from blood cultures. Pneumonia occurred in 6.3 per cent of patients. A total of 207 surgical procedures was performed on 113 of the 193 patients.(ABSTRACT TRUNCATED AT 250 WORDS)     

Epidemiological pattern of adult burn injuries

An epidemiological survey of 411 patients over a period of five and a half years is analysed. There were no yearly trends but there was a slight increase in the number of female burns during the survey. There were 293 males, 71.3 per cent and 118 females, 28.7 per cent. The majority of the burns occurred in the younger age groups and reflect the cause of the injury. Approximately one-half of the injuries were burns of less than 10 per cent and three-quarters were of less than 20 per cent. The most extensive burns were caused by petrol and clothes fires. Predisposing conditions were present in 23.8 per cent of the patients, with alcohol abuse figuring prominently. Epilepsy was present in 2.7 per cent of the patients. The major predisposing conditions, causes and complications of the burn injuries are discussed. Burn infection occurred in 18.2 per cent of the patients and septicaemia in 3.5 per cent. There was a mortality rate of 8.3 per cent and the average length of hospital stay was 22.9 days. While these burns are mainly preventable it is difficult to see how this can be fully achieved.     

Epidemiology and mortality of adult burns in Catalonia.

Burn injuries still produce significant morbidity and mortality in developed countries. The incidence of burns in Catalonia is similar to other countries, with 31.2 per 100000 person/year referred to a specialized unit for definitive treatment. The Burn Center of the Vall d'Hebron hospital system is located at the General Hospital. It is the only facility for burns in the state of Catalonia. The catchment population is 6 million people, with 1814 +/- 89 burned patients treated in the emergency room per year and 396 +/- 15 of them admitted per year. Overall mortality is 3.49%. Inhalation injury and ARDS have a low incidence in our series with a high mortality. Factors associated with an increase in mortality are contact burns, inhalation injury, age and burn size. Pre-existing conditions did not affect survival in our series and 75% of all deaths occurred in the first week. Patients were treated with early serial debridement and cerium nitrate sulfadiazine, with results comparable to others in the literature. Mortality rates were compared to the Abbreviated Burn Severity Index, with a disparity in results, advocating the necessity to find a better and more applicable prognostic test for the outcome of burn injuries.     

Paediatric burn injuries in New England, USA

The authors analysed a subset of data from the New England Regional Burn Program (NERBP) to describe the epidemiology of burn injuries for children aged from birth to 19 years in the six-state New England area of the USA. The subset of the NERBP data analysed pertained to residents of the six New England states who were admitted to hospital for the treatment of a burn injury sustained between 1 July 1978 and 30 June 1979. Analysis of the data revealed that 1128 (41 per cent) of the 2742 hospitalized burns identified occurred to persons between the ages of birth and 19 years, yielding an overall burn incidence rate of 30.7 burns per 100,000 person-years. Children aged from birth to 2 years sustained a higher burn rate, 96.7 burns per 100,000 child-years, than did children in any other age category. The burn rate for males was higher than the rate for females in each age category, as were the rates for black children compared to white children. Children in Massachusetts experienced the highest overall burn rate among the six New England states; the lowest rate occurred in New Hampshire. Overall, 63 per cent of the burns occurred in a residential setting. The most common activities related to burn injury were food preparation and food consumption, which accounted for 471 (42 per cent) of the burn injuries.     

Management of acute calvarial burns in children

BACKGROUND: Although rare, head burns involving the calvarium are a serious complication of burns and electrical injury, and present therapeutic challenges to the surgical burn care team. We evaluated our experiences and compared available strategies to address this challenge. METHODS: Records of all burned children between January 1986 and December 2000 were reviewed. Twenty-seven children (15 boys and 12 girls) with scalp burns extending at least into the outer table of bone were identified and compared with a matched group of 30 patients admitted for acute thermal burns without skull injury. RESULTS: Flame burn was the injury mechanism in 78% of these patients and electrical injury was the injury mechanism in 22%. The incidence of calvarial burns in our patient population was 1.2% for thermal burns and 5.6% for electrical injuries during the study period. The age distribution was biphasic, with maximums in infancy for thermal burns and in puberty for electrical injuries. Eight of 27 patients (29.6%) developed full-thickness calvarial bone defects. In 23 patients, calvarial burn wound coverage was achieved with bone debridement and immediate or delayed placement of autograft skin. In four patients (all with electrical injury), local scalp flaps were required for closure. The length of hospital stay and overall number of acute operative procedures significantly increased for patients with calvarial burns. CONCLUSION: Acute calvarial burns are safely managed by bone debridement in combination with staged autografting or early flap coverage. Although flap coverage reduces the number of required procedures, the extensive wound size in thermal burns restricts acute flap procedures primarily to electrical injuries. Compared with patients without skull injury, length of hospital stay and the number of acute operative procedures are tremendously increased in patients with calvarial burns.     

Etiology and outcome of burns in Tabriz, Iran. An analysis of 2963 cases.

BACKGROUND AND AIMS: Burn injuries still produce a significant morbidity and mortality in Iran. A 3-year retrospective review of burn victims hospitalized at a major burn center was conducted to determine the etiology and outcome of patients in Tabriz. MATERIAL AND METHODS: Two thousand nine hundred sixty + three patients were identified and stratified by age, sex, burn size, presence or absence of inhalation injury, cause of burn. There is one burn center in the East Azarbygan province serving 3.3 million people over an area of 47,830 sq.km. RESULTS: The overall incidence rates of hospitalization and death were 30.5% and 5.6% per 100000 person years. The mean patient age was 22 years, and the male: female ratio was 1.275. There were 555 deaths altogether (18.7%). The highest incidence of burns was in the 1-9 age group (29.2%). Patients with less than 40 percent of burned surface constituted 79.8% of injuries. The most common cause of burns was kerosene accident in adults and scald injuries in children. The mean length of hospitalization was 13 days. The mean body surface area burned was larger with higher mortality in females than in males (p < 0.001). Inhalation injuries were strongly associated with large burns and were present in all flame-burn fatalities. CONCLUSION: In our opinion, social factors are the main drive leading to an unacceptably high rate of burn injuries in our societies. Most of the burn injuries were caused by domestic accidents and were, therefore, preventable; educational programs might reduce the incidence of burn injuries.     

A policy of early excision and grafting in elderly burn patients shortens the hospital stay and improves survival

Early excision and grafting of the burn wound appears to shorten the hospital stay and decrease mortality in children and adults. However, whether an early surgical approach is safe in elderly burn patients has not been resolved. To answer this question we carried out a prospective study of early surgery in 114 consecutive patients over the age of 50 years. Patients were generally operated on between post-burn days 2 and 5. The mean age of the patients was 68 years, with a burn size of 22 per cent, of which 13 per cent was full thickness skin loss. The mean hospital stay of the surviving patients was reduced by 40 per cent compared to national averages (P less than 0.001). The mortality rate for the entire group of patients was 17 per cent, with 2 deaths in the 65 patients with burns less than 20 per cent total body surface area (TBSA). Although the mortality rate for patients with burns greater than 20 per cent TBSA was 35 per cent, this was less than predicted (P less than 0.05). The improvement in survival appeared to be due to a decrease in the incidence of lethal burn wound infections.     

Hand burns in children under 5 years of age

In order to evaluate the epidemiology and functional results of hand burns in young children, 92 consecutive patients (126 hand burns) under age 5 years admitted to a Burn Center were reviewed. Scald burns (49 per cent) were most common, followed by flame (34 per cent), contact (14 per cent) and electrical burns (3 per cent). The child was left unattended by an adult in 53 per cent of cases and documented abuse was present in 6 per cent. The mean total body surface area (TBSA) burned was 17 per cent, and 77 patients (85 per cent) had additional burns in other areas (arms 34 per cent, legs 31 per cent, chest 29 per cent and face 27 per cent).

Palmar burns occurred in 24 hands (19 per cent), dorsal in 41 (33 per cent), while both surfaces were burned in 61 (48 per cent). Joints involved included the MP in 96 (76 per cent). PIP in 87 (69 per cent) and DIP in 80 (63 per cent). The depth was superficial partial thickness in 53 (47 per cent), deep partial in 55 (44 per cent), and full thickness in 18 hands (14 per cent); a total of 29 hands were grafted (15 deep partial and 14 full thickness). Escharotomies were required in 12 hands (9 per cent) (9 flame and 3 scald) and partial amputation of digits was required in 3 (2 per cent).

Follow-up was available in 46 hands from 7 to 120 months (mean 39 months). Partial thickness burns (34) healed with normal (32) or near-normal (2) hand function and developmental delay occurred in one patient. Hand function in 12 full thickness burns was normal in 9, decreased in 3 with developmental delay in 2 patients. The number of reoperations required per hand burned after hospital discharge varied with age (2 years and under 1.2 vs. over 2 years 0.6), depth (deep partial 0.4 vs. full thickness 1·6) and surface involved (palmar 1.3 vs. dorsal 0.1 vs. both 1.5), indicating that children under 2 years with full thickness palmar burns are at increased risk of developing burn scar deformities requiring surgical correction. Although 24 total reoperations were required in 25 deep partial and full thickness hand burns, residual burn scar deformities were present in only 2 hands at follow-up (1 boutonniere and I web space contacture).

It is concluded that the overall outcome of hand burns in this age-group is good and developmental delay is rare with proper acute management and prompt surgical correction of burn scar deformities.     

Epidemiology and mortality of burns in the South West of Iran

Burn injuries still produce a significant morbidity and mortality in Iran. This study was carried out to analyze the epidemiology, mortality, and current etiological factors of 2043 burn patients who were admitted to the burn centers in the Fars province during 4 years (1994-1998). There were two burn centers in the Fars province serving 3817036 people over an area of 124,000 km(2). The overall incidence rates of hospitalization and death were 13.4 and 4.6 per 100000 person-years. The mean age was 21.9 years, and 51% of patients were children under 19-years-old. The highest rates of hospitalization and death were observed in the elderly (80 years). Also young females (20-29 years) had a high rate of hospitalization. Thus, 55% of the patients had BBS less than 40%. Burn injuries were more frequent and larger with higher mortality in females than in males (P<0.0001). There was also statistically significant correlation between age groups, gender, and BBS with mortality rate (P<0.0001). Flame was the most common etiology of burns. There was also significant correlation between age groups and type of burns (P<0.0001). Suicide attempts for all the patients > or = 11 years were the cause of 41.3% (256/620) of the burns involving women and of 10.3% (40/388) of the burns involving men. The overall case fatality rate was 34.4%. The mortality rate was significantly higher for self-inflicted burns (78%) than for accidental burns (26.7%). Most of the lesions requiring hospital admission occurred during the winter months. Factors associated with an increase in mortality were suicidal burns, burn size, age, and flame burns. Most of the burn injuries were caused by domestic accidents and were, therefore, preventable.     

Epidemiological survey of burns treated in Ankara, Turkey and desirable burn-prevention strategies

From 1 January 1979 to 31 December 1993, 1109 patients were admitted to our burn unit located at Hacettepe University. Of the patients, 638 (57.5 per cent) were children (under the age of 16 years). The male to female ratio was 1.4: 1 in children, and was approximately 2.6: 1 for patients over 16 years of age. Of the 638 paediatric patients, 67 (10.5 per cent) sustained electrical burns. The causes of injury in the remaining 571 cases (89.5 per cent) were hot liquids in 379 (66.4 per cent of the non-electrical burns), flame in 190 (33.3 per cent) and contact burns in two (0.3 per cent). Of the scalds, 296 (78.1 per cent of the scalds), 52 (13.7 per cent), 22 (5.8 per cent) and nine (2.4 per cent) were caused by hot water, milk, meal and oil respectively. Of the flame burns, 21 (11.1 per cent) were due to LPG explosions.

Of the 471 adult patients (over 16 years), 159 (33.8 per cent) were injured by electricity. The causes of non-electrical burn injuries were: hot liquid in 25, flame in 274, chemical agents in four, contact in four, and other causes in four. Although our centre is located in Central Anatolia, 41.8 per cent of all patients were referred from the other six regions of Turkey. Of the 1109 inpatients, 645 (58.2 per cent) were injured in Central Anatolia, 279 (25.2 per cent) in the Black Sea Region, 55 (5.0 per cent) in the Mediterranean Region, 18 (1.6 per cent) in the Marmara Region, 34 (3.1 per cent) in the Aegean Region, 52 (4.7 per cent) in Southeastern Anatolia and 26 (2.3 per cent) in Eastern Anatolia. Approximately two-thirds of the patients (419) required one or more surgical interventions, including debridement and grafting, as well as amputation. The most important early complications were acute renal failure (148 patients −13.3 per cent), sepsis (660 patients −59.5 per cent) and gastrointestinal haemorrhage (seven patients −0.6 per cent). The overall mortality rate was 34.4 per cent. The epidemiological pattern of the burns showed that emergency measures should be taken to prevent scalding accidents to children throughout the country, and for electrical burns in adults, particularly those living in the Black Sea Region. In establishing, implementing and directing prevention programmes, regional differences should be taken into consideration.     

Thermal injury in the elderly: when is comfort care the right choice?

The factors contributing to a higher mortality rate in elderly thermal injury victims are not well delineated. The purpose of this study is to determine the impact of the initial injury, medical comorbidities, and burn size on patient outcome and to determine a level of injury in this population when comfort care is an appropriate first choice. Individual medical records of patients over 65 years of age admitted to our burn center over a 10-year interval were reviewed for patient demographics, mechanism of injury, total body surface area (TBSA) burned, medical comorbidities, use of Swan-Ganz catheters, evidence of inhalation injury, level of support, and patient outcome. The mechanisms of thermal injury were flame (68%), scald (21%) and electrical or chemical contact (11%). Twenty-six preventable bathing, cooking, and smoking-related injuries were seen (33%). The average TBSA was 25 per cent. Average length of stay varied depending on outcome. The overall mortality rate for this group was 45 per cent. Patients older than 80 years with 40 per cent or greater TBSA burned had a 100 per cent mortality rate despite aggressive treatment. Burn wound size correlated better with probability of poor outcome than age. Thermal injuries in the elderly are becoming more important with the aging of our population. Underlying medical problems--specifically chronic obstructive pulmonary disease--do play a role in increased patient morbidity and mortality. This study shows that age greater than 80 years in combination with burns greater than 40 per cent TBSA are uniformly fatal despite aggressive therapy. We believe that delaying the start of comfort-only measures in this situation only prolongs the pain and suffering for the patient, the family, and the physician.     

Volkmann’s contracture in high-voltage electrical injury

Burn injuries are a common form of trauma, it occurs in 1% of the population of Australasia each year. Of these injuries, the devastating effects of high-voltage electrical burns in deep-tissue injury causing compartment syndrome and subsequent Volkmann’s ischemic contracture are well documented. This report highlights the importance of early recognition of the severe electrical burn injury and its clinical consequences. Early identification through vigilant monitoring and diagnostic adjuncts, together with early intervention, whether conservative monitoring or operative management is of utmost importance in the prevention of ongoing complications and recovery from injury.     

Burns in patients over 60 years old: epidemiology and mortality.

Epidemiology and mortality among burn patients over age 60 years who were admitted to the Burn Centre of La Fé Hospital (Valencia, Spain) between 1 January 1988 and 1 January 1991 have been studied. A total of 443 patients (7.8 per cent of all presenting patients) were hospitalized during this 3-year period; of these, 69 (15.5 per cent) were over 60 years old. There were 40 females and 29 males (mean age, 72.2 years). Mean burn area was 21.6 per cent of total body surface, and the most commonly involved regions were the lower limbs (81 per cent). Fire flames were the most common cause of burns (65.2 per cent) and produced the most extensive lesions. Eight-five per cent of the accidents occurred at home, and winter was the season of highest incidence. Patient mortality was 33.3 per cent, the most common causes of which were hypovolaemic shock during the first 24 h and pneumonia in the later stages.     

Retrospective evaluation of admission criteria for paediatric electrical injuries

In the medical community, the practice of admitting all electrical burns for 24–48 h of observation, monitoring and laboratory evaluation is widespread. This retrospective review of paediatric electrical burns was conducted to determine which patients may safely be treated as outpatients.

Retrospective analysis of all paediatric burns admitted between 1980 and 1991 identified 35 patients with electrical injuries. Patients were divided into two groups for analysis: those burned by exposure to household voltages (120–240 V; n=26) and those exposed to high voltages, in excess of 1000 V (n=9).

The majority of household electrical injuries occurred secondary to contact with the household 120 V (21/26). Contact with an extremity accounted for the largest number of these injuries (18/26). The mouth was the second most frequent site of injury (7/26). Most of these patients (20/26) had < 1 per cent BSA burn. No patient in the household-voltage group had an arrythmia that required treatment, nor were there any identified examples of compartment syndrome or other vascular complications. Seven patients did require minimal skin grafting. No deaths occurred in either group.

The patients in the household-voltage group were significantly younger. High-voltage electrical injuries occurred in an older patient population and required more aggressive care and surgical intervention. This was evident at the time of initial evaluation. Based on these data, healthy children with small partial-thickness electrical burns and no initial evidence of cardiac or neurovascular injury do not appear to need hospital admission.     

The problems and prevention of burns in developing countries

Burns are rapidly assuming greater importance as a cause of ill health in the developing nations. The major factors include gross ignorance of fire prevention, the quick spread of slums and the persistence of old traditional customs and beliefs. One hundred and forty-one new cases of burns were treated at the University of Calabar Teaching Hospital (UCTH) in a 2-year period from January 1984 to December 1985. A large proportion of the patients (91, or 64.5 per cent) were minor burns, while 40 (28.4 per cent) were serious burns, and 10 patients (7.1 per cent) suffered major burns. Thirteen patients (9.2 per cent) left hospital against medical advice or absconded without completing their treatment. There were six deaths (4.3 per cent), most of the deaths occurred in the major burns group. Lack of drugs and intravenous fluids, delay in bringing the patients to hospital, ignorance, superstition and old cultural and traditional beliefs contributed to the morbidity and mortality. Most of the burn injuries were caused by domestic accidents and were therefore preventable.     

Adult kitchen-related burn injuries: The impact of COVID-19

IntroductionKitchen-related burn injuries are common and preventable. To limit the spread of COVID-19, public health orders encouraged the public to stay at home which may have led to an increase in kitchen-related burn injuries.ObjectiveTo assess adult kitchen-related burns treated in an outpatient setting in general, and especially looking at the impact of the COVID-19 pandemic on the incidence and epidemiology of these burns.MethodsFor this retrospective, population-based study, data were obtained for adult patients who suffered burn injuries resulting in a visit to a Canadian tertiary Burn Clinic between April 2016 and March 2021 specifically looking at demographics, burn etiology, severity and anatomical location and the need for surgery. Separately, we compared the patients before and after the beginning of the COVID-19 pandemic (April 1, 2020).ResultsA total of 1380 burn patients were identified. Of these, 38 % (N = 521) sustained a kitchen-related burn. The median patient age was 40 years (range 18–95) and 282 (54.1 %) were female. The most common etiology and location were scald (76.8 %) and anterior arm (28.5 %), respectively. Thirty-two (6.1 %) patients required admission to the Burn Unit and 26 of these had surgeries. Additionally, 72 (13.8 %) patients had surgery as an outpatient. During the COVID-19 pandemic, East Asian patients saw a significant increase in kitchen burns (p < 0.01).ConclusionOver 1/3 of burns at the outpatient burn clinic were kitchen-related. About 94 % of these were treated as outpatient only. The incidence of kitchen-related burns did not change during the COVID-19 pandemic, but we found significant differences in ethnic distribution. These results provide a unique opportunity to focus on communication and education and set up preventative measures.     

Profile of the paediatric burn patient in a Canadian burn centre.

Five hundred and eighty-three children (0-18 years old), consisting of 33.4 per cent of all burn inpatients, were admitted to the University of Alberta Hospitals over an 11-year period (January 1978 to December 1988). Demographic and outcome variables, in addition to aetiological factors, were examined. 48.4 per cent of burns occurred in children less than 4 years of age, with males predominating in every age group (P less than 0.001). Children had smaller burns, a higher incidence of scalds, less inhalation injuries and a lower mortality compared to adult burn patients admitted over the same time period (P less than 0.05). There was a low incidence of confirmed child abuse by burns (1.4 per cent). High-risk environments identified were the home (74.6 per cent of burns) and recreational settings (12.4 per cent of burns), mainly occurring around campfires. Native children were overrepresented in the burn population compared to the general population by a factor of approximately 10:1. Scald prevention, high-risk environments (home and recreational), high-risk populations (male and natives) and unsafe practices with flammable liquids (petrol in particular) should be emphasized in paediatric burn prevention programmes.     

Epidemiology of isolated adult lower limb burns over 15 years with a focus on preventable work-related injuries

Our aim was to describe the epidemiology of isolated adult lower limb burns presenting to the Pinderfields Regional Burns Centre, Wakefield, United Kingdom between 2003 and 2018. Data was obtained using our local records of the international Burn Injury Database (iBID).6059 patients were treated in our department during this period. 18.7% presented with isolated lower limb burns (n = 1133). 65.4% of patients were male (n = 741). Scald was the most common mechanism of injury. Work-related burns accounted for 23.4% of the injuries (n = 265).36% of patients were admitted (n = 408), and 11.7% underwent surgical intervention (n = 133).Isolated lower limb burns are common in patients in the working age group. Work-related injuries are preventable. Targeted education to highlight the risks, reduce the incidence, and improve awareness of first aid measures are recommended.     

Economic burden of burn injuries in the Netherlands: A 3 months follow-up study

IntroductionBurn care has rapidly improved in the past decades. However, healthcare innovations can be expensive, demanding careful choices on their implementation. Obtaining knowledge on the extent of the costs of burn injuries is an essential first step for economic evaluations within burn care. The objective of this study was to determine the economic burden of patients with burns admitted to a burn centre and to identify important cost categories until 3 months post-burn.Patients and methodsA prospective cohort study was conducted in the burn centre of Maasstad Hospital Rotterdam, the Netherlands, including all patients with acute burn related injuries from August 2011 until July 2012. Total costs were calculated from a societal perspective, until 3 months post injury. Subgroup analyses were performed to examine whether the mean total costs per patient differed by age, aetiology or percentage total body surface area (TBSA) burned.ResultsIn our population, with a mean burn size of 8%, mean total costs were €26,540 per patient varying from €742 to €235,557. Most important cost categories were burn centre days (62%), surgical interventions (5%) and work absence (20%). Flame burns were significantly more costly than other types of burns, adult patients were significantly more costly than children and adolescents and a higher percentage TBSA burned also corresponded to significantly higher costs.Discussion and conclusionMean total costs of burn care in the first 3 months post injury were estimated at €26,540 and depended on age, aetiology and TBSA. Mean total costs in our population probably apply to other high-income countries as well, although we should realise that patients with burn injuries are diverse and represent a broad range of total costs. To reduce costs of burn care, future intervention studies should focus on a timely wound healing, reducing length of stay and enabling an early return to work.     

An analysis of 1704 burn injuries in Hong Kong children

Over a 12-month period, 1704 children less than 15 years old with burn injuries seen in the accident and emergency departments of seven major regional hospitals in Hong Kong were analysed with respect to their epidemiological data. The age group with the highest risk for injury was 0-4 years (57 per cent) and with a maximum at 1-2 years of age. Boys showed a significantly higher incidence of burns than girls at any age. Ninety-three per cent of the accidents occurred at home and 92 per cent were scalds caused by hot water and other fluids. In the great majority of patients the total body area of burn did not exceed 5 per cent. Younger children had a higher incidence of burns involving the head, face and anterior trunk, 39 per cent of the 0-4 year age group required hospital admission. During the winter months, the children tended to suffer from deeper burns.
