Course of prevalence of scar contractures limiting function: A preliminary study in children and adolescents after burns

Epidemiological and clinical features of paediatric inpatients for scars: A retrospective study

OBJECTIVES

To describe the epidemiological and clinical features of paediatric scar inpatients and then to facilitate therapeutic schedule for children with scars.

METHODS

In this cross-sectional study, data of patients admitted for scar treatment in 1064 tertiary hospitals from 2013 to 2018 were extracted through the Hospital Quality Monitoring System (HQMS) database. Demographic and clinical features of children with scars were analysed statistically and highlighted compared with those of adults and the elderly scar cases.

RESULTS

In this study, 53,741 paediatric scar cases, accounting for 30.29% of all hospitalized for scar, were analysed. Compared to adults and the elderly, children with scars were mainly males (62.27% vs 50.98% vs 49.85%, P < 0.001) and were vulnerable to scalds (37.10%) and operative intervention (34.11%). Although the scalp/face/neck was the most common affected location, the proportion of scars involving upper limbs (27.88% vs 21.69% vs 7.28%, P < 0.001), lower limbs (15.14% vs 10.28% vs 6.56%, P < 0.001) and perineum (4.59% vs 3.13% vs 2.65%, P < 0.001) was higher in children than that in other two groups. Scar contracture was the most common complications in children (45.27%). Nearly 66% of paediatric scar cases received surgical treatment during hospitalization, among whom release of lesion was the most frequent operation (56.35%). The proportion of keloids was relatively lower in child cases than in other two groups (6.20% vs 14.48% vs 18.15%, P < 0.001). Additionally, the median LOS in child cases was 9 (5-15) days, slightly exceeding that in adult/elderly cases.

CONCLUSIONS

Scars were common inducing factors of hospitalization and contributed greatly to the disease burden of children. More attention should be paid to those who are males, burn survivors, or skin-injured at extremities and perineum to improve therapeutic strategies and prognoses for paediatric scar patients.

Management of Severe Extended Burn Axillary Contracture in a Low-resource Setting

Contracture is a common complication of deep burn injury, affecting up to one-third of patients. Although some degree of contracture occurs in any setting, severe extended axillary contractures are more often due to unavailable or inappropriate care. Very few cases have been described in the literature. Their management can be especially challenging in a low-resource environment. The purpose of this article is to present two cases in which severe postburn axillary contractures were effectively managed in a low resource setting, using an island perforator flap coupled with a skin graft or advancement flap. In severe extended axillary contracture, more than one technique is often required to cover the large defect created after contracture release.

Immediate Application of Biodegradable Temporizing Matrix To a Muscle Free Flap for Complex Soft Tissue Reconstruction

Background. Extensive degloving skin injuries in children are particularly challenging for the possible complications of restricting growth and function. Biodegradable temporizing matrix (BTM, PolyNovo) is traditionally used for acute burn care reconstruction and in this case was successfully used to manage a child with lower limb open fractures associated with severe degloving injuries. This novel use offers excellent short and intermediate outcomes.

Influence of agents and mechanisms of injury on anatomical burn locations in children <5 years old with a scald

OBJECTIVE

To demonstrate how the mechanism and agent of injury can influence the anatomical location of a scald.

DESIGN

Prospective multicentre cross-sectional study.

SETTING

20 hospital sites across England and Wales including emergency departments, minor injury units and regional burns units.

PATIENTS

Children aged 5 years and younger who attended hospital with a scald.

MAIN OUTCOME MEASURES

Primary outcome: a descriptive analysis of the mechanism, agent and anatomical location of accidental scalds. Secondary outcome: a comparison of these factors between children with and without child protection (CP) referral.

RESULTS

Of 1041 cases of accidental scalds, the most common narrative leading to this injury was a cup or mug of hot beverage being pulled down and scalding the head or trunk (132/1041; 32.9% of cases). Accidental scalds in baths/showers were rare (1.4% of cases). Accidental immersion injuries were mainly distributed on hands and feet (76.7%). There were differences in the presentation between children with accidental scalds and the 103 who were referred for CP assessment; children with scalds caused by hot water in baths/showers were more likely to get referred for CP assessment (p<0.0001), as were those with symmetrically distributed (p<0.0001) and unwitnessed (p=0.007) scalds.

CONCLUSIONS

An understanding of the distributions of scalds and its relationship to different mechanisms of injury and causative agents will help clinicians assess scalds in young children, particularly those new to the emergency department who may be unfamiliar with expected scald patterns or with the importance of using appropriate terminology when describing scalds.

The morbidity associated with paediatric burn wound escharotomies

INTRODUCTION

An escharotomy is an effective surgical procedure for the rapid decompression of a constricting and unyielding eschar, to permit restoration of blood flow. However, an escharotomy is also a full-thickness incision, which adds additional scarring to the burn injury area. The cosmetic and functional morbidity of escharotomy scarring in children is poorly characterised.

METHODS

Children who required a burn wound escharotomy at the Queensland Children's Hospital (QCH) between May 2011 and May 2020 were included. Demographics of these children were described. In addition, the number of operations for revision of escharotomy scars was recorded as an indicator of functional or cosmetic concern.

RESULTS

A total of 19 patients required an escharotomy after a burn injury. Children with 1% to 96% TBSA burns required an escharotomy, with a median of 28% (IQR 10-39%) TBSA. Two patients (81% and 96% TBSA) died. Seventy-one percent (12/17) of survivors had operative revisions of their escharotomy scars. The median time from burn to first scar intervention was 35 weeks (IQR 19-70 weeks).

CONCLUSION

There is substantial morbidity associated with escharotomies in children. Further investigation of the current methods of decompression after burn injury, and the long-term morbidity of escharotomy, is required.

Prevalence and predictors of scar contracture-associated re-hospitalisation among burn inpatients in China

Scar contracture, a common destructive complication causing increased re-hospitalisation rate of burn survivors and aggravated burden on the medical system, may be more seriously in Chinese population because of their higher susceptibility to scar formation. This study aims to evaluate the prevalence and predictors of scar contracture-associated re-hospitalisation among Chinese burn inpatients. This cross-sectional study screened burn inpatients hospitalised during 2013 to 2018 through the Hospital Quality Monitoring System database, among whom re-hospitalised for scar contracture were identified. Variables including sex, age, occupations, burn area, burn site and surgical treatment were analysed. Potential predictors of scar contracture-associated re-hospitalisation among burn inpatients were determined by univariate regression analyses. Of the 220,642 burn inpatients, 2146 (0.97%) were re-hospitalised for scar contracture. The re-hospitalised inpatients were predominantly men and blue-collar workers, showing younger median age at the time of burns, larger burn sizes, and higher percentage of surgical treatment compared other burn inpatients. Significant univariate predictors of scar contracture-associated re-hospitalisation included male sex, age < 50 years, blue-collar work, ≥ 40% total body superficial area burned, inhalation injured, and surgical treatment. Scar contracture is an intractable complication and a significant factor to increase re-hospitalisation rate among Chinese burn inpatients.

The development of burn scar contractures and impact on joint function, disability and quality of life in low- and middle-income countries: A prospective cohort study with one-year follow-up

OBJECTIVE

The aim of this study was to assess the development of burn scar contractures and their impact on joint function, disability and quality of life in a low-income country.

METHODS

Patients with severe burns were eligible. Passive range of motion (ROM) was assessed using lateral goniometry. To assess the development of contractures, the measured ROM was compared to the normal ROM. To determine joint function, the normal ROM was compared to the functional ROM. In addition, disability and quality of life (QoL) were assessed. Assessments were from admission up to 12 months after injury.

RESULTS

Thirty-six patients were enrolled, with a total of 124 affected joints. The follow-up rate was 83%. Limited ROM compared to normal ROM values was observed in 26/104 joints (25%) at 12 months. Limited functional ROM was observed in 55/115 joints (48%) at discharge and decreased to 22/98 joints (22%) at 12 months. Patients who had a contracture at 12 months reported more disability and lower QoL, compared to patients without a contracture (median disability 0.28 versus 0.17 (p = 0.01); QoL median 0.60 versus 0.76 (p = 0.001)). Significant predictors of developing joint contractures were patient delay and the percentage of TBSA deep burns.

CONCLUSION

The prevalence of burn scar contractures was high in a low-income country. The joints with burn scar contracture were frequently limited in function. Patients who developed a contracture reported significantly more disability and lower QoL. To limit the development of burn scar contractures, timely access to safe burn care should be improved in low-income countries.

Burn scar contracture release surgery effectively improves functional range of motion, disability and quality of life: A pre/post cohort study with long-term follow-up in a Low- and Middle-Income Country

OBJECTIVE

Burn scar contractures limit range of motion (ROM) of joints and have substantial impact on disability and the quality of life (QoL) of patients, particularly in a Low- and Middle-Income Country (LMIC) setting. Studies on the long-term outcome are lacking globally; this study describes the long-term impact of contracture release surgery performed in an LMIC.

METHODS

This is a pre-post cohort study, conducted in a referral hospital in Tanzania. Patients who underwent burn scar contracture release surgery in 2017-2018 were eligible. ROM (goniometry), disability (WHODAS 2.0) and QoL (EQ-5D) were assessed. The ROM data were compared to the ROM that is required to perform activities of daily living without compensation, i.e. functional ROM. Assessments were performed preoperatively and at 1, 3, 6 and 12 months postoperatively.

RESULTS

In total, 44 patients underwent surgery on 115 affected joints. At 12 months, the follow-up rate was 86%. The mean preoperative ROM was 37.3% of functional ROM (SD 31.2). This improved up to 108.7% at 12 months postoperatively (SD 42.0, p < 0.001). Disability-free survival improved from 55% preoperatively to 97% at 12 months (p < 0.001) postoperatively. QoL improved from 0.69 preoperatively, to 0.93 (max 1.0) at 12 months postoperatively (p < 0.001). Patients who regained functional ROM in all affected joints reported significantly less disability (p < 0.001) and higher QoL (p < 0.001) compared to patients without functional ROM.

CONCLUSIONS

Contracture release surgery performed in an LMIC significantly improved functional ROM, disability and QoL. Results showed that regaining a functional joint is associated with less disability and higher QoL.

Lower limb functional status and its determinants in moderate/major burns 3-6 months following injury: A two-center observational study

INTRODUCTION

Severe complications which may cause impaired physical functionoften develops over time following severe burn to the lower extremities. The purpose of this study was to clarify the clinical determinants of lower limb functional status, functional mobility and exercise capacity in moderate/major burns 3-6 months following the injury.

METHODS

The study included 42 patients, 12 with moderate injury and 30 with major injury, aged 19-59 years old. Lower Limb Functional Index was used to determine the lower limb functional status. Functional mobility and exercise capacity were evaluated with the Timed Up and Go test and the 6-min walk test, respectively. Scar quality and kinesiophobia were assessed with the Patient and Observer Scar Assessment Scale (POSAS) and the Tampa Scale for Kinesiophobia, respectively. Active range of motion (ROM) was measured with a universal goniometer.

RESULTS

Significant and independent predictors of lower limb functional status, functional mobility and exercise capacity related to POSAS score, kinesiophobia level, gender, burn severity, the number of operations, the presence of burnsinvolving any of the lower limb joints, knee ROM limitations, limitation in any of the lower limb joint ROMs, comorbidities, and truncal burns (p < 0.05).

CONCLUSIONS

Burn characteristics and clinical evaluations of patients are important determinants of the lower limb functional status, mobility and exercise capacity in burn patients. These predictors should be considered to improve physical functions related to the lower limb when creating a personalized rehabilitation program.
