This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:
To assess the effects of pressure garment therapy for the prevention of hypertrophic scarring after burn injury.
Background. Burn injuries are a common cause of preventable morbidity and mortality. In all societies, burns continue to constitute a medical, psychological and economic problem. Burn wounds are one ...of the most common surgical emergencies leading to hospitalisation. Objectives. To understand the profile of patients with burn injuries presenting to Mankweng Hospital in Polokwane, Limpopo Province, South Africa. Methods. This was a retrospective study using a descriptive quantitative design to analyse the profile of all patients admitted consecutively to the Mankweng Hospital burns unit from 1 January 2018 to 31 December 2020. Results. During the study period, a majority of males (n=412; 56.7%) were admitted, indicating a significant sex difference. Conclusion. Children aged <5 years were found to be more affected than any other age group. Males were more affected than their female counterparts. Scalds and flame burns were the most common burn injuries.
Ocular burns are ophthalmic emergencies that can cause devastating injuries. This study aimed to analyze the epidemiology, complications, and management of ocular-periocular burns.
A total of 193 ...patients with ocular-periocular burns were admitted to our tertiary hospital from January 2018 to December 2020. The demographic characteristics of the patients, injury variables, complications, and treatments were evaluated.
There were 142 male (73.6%) and 51 female (26.4%) patients with a mean age of 32.53±17.75 years. The average total body surface area was 12% (range, 1–80%). Injuries were most common at work (52.3%) and home (36.3%). Thermal burns were the most common injuries (74.6%), followed by chemical (14.5%) and electrical burns (10.9%). Alkaline agents (75.0%), mainly sodium hydroxide and lime, were common in chemical burns. Superficial lid burns were significantly higher in the thermal group (p < 0.001), and grade III-IV corneal burns were significantly higher in the chemical group (p < 0.001). Various complications were developed in 50 (13%) eyes. Medical treatment only was performed in 318 (82.4%) eyes, and additional surgical treatment was performed in 64 (17.6%) eyes; however, 54 (14.0%) underwent more than one surgery. The most common complications were corneal scars (7.3%), limbal deficiency (4.1%), and ectropion (3.9%). The most frequent procedures performed were amniotic membrane transplantation (AMT) (11.9%) and tarsorrhaphy (6.7%).
Chemical burns, limbal and conjunctival ischemia, and full-thickness eyelid defects had a poor prognosis. The degree of limbal deficiency and ınjury of intraocular structures were found to have a great influence on the outcome of their visual acuity.
IMPORTANCE Although several reports are available on the use of conventional and cultured limbal epithelium using various substrates in the treatment of limbal stem cell deficiency (LSCD), the ...patient populations studied have been largely adults. Thus, to our knowledge, the outcomes of this procedure exclusively in a pediatric population have not been reported previously. OBJECTIVE To report the outcomes of autologous ex vivo cultivated limbal epithelial transplantation (CLET) in pediatric patients with LSCD after ocular burns. DESIGN AND SETTING A retrospective, interventional case series of patients treated at the L. V. Prasad Eye Institute, Hyderabad, India. PARTICIPANTS Children up to 15 years with LSCD secondary to chemical or thermal injury who underwent CLET from April 1, 2001, through June 31, 2010, with a follow-up of at least 1 year, were included in the study. INTERVENTION After a limbal biopsy specimen obtained from a healthy area of the limbus, the limbal epithelial cells were cultured on a denuded human amniotic membrane substrate using a xeno-free explant culture technique. A monolayer of cultivated epithelial cells along with the amniotic membrane was transplanted on the patient's affected eye after pannus excision. In cases of failure, the same procedure was repeated. MAIN OUTCOMES AND MEASURES Ocular surface stability and visual improvement were the primary and secondary outcome measures, respectively. Success was defined as a stable corneal epithelium without conjunctivalization. Eyes with conjunctivalization and persistent epithelial defects were classified as failures. RESULTS Of the 107 eyes of 107 patients included in this study, 73 eyes (68.2%) underwent 1 and 34 eyes (31.8%) underwent 2 autologous CLET procedures. At a mean follow-up of 3.4 years, 50 eyes (46.7%) achieved completely epithelialized, avascular, and stable ocular surfaces. At the final visit, 58 eyes (54.2%) had improvement in visual acuity of 0.2 or more logMAR units. CONCLUSIONS Autologous CLET was successful in restoring the ocular surface and improving vision in almost half of the children blinded by ocular burns.

Ocular chemical burns are an ophthalmic emergency and are responsible for 11.5%–22.1% of ocular injuries. Immediate copious irrigation is universally recommended in acute ocular burns to remove the ...offending agent and minimize damage. Conventional medical therapy consists of the use of agents that promote epithelialization, minimize inflammation, and prevent cicatricial complications. Biological fluids such as autologous serum, umbilical cord blood serum, platelet-rich plasma, and amniotic membrane suspension are a rich source of growth factors and promote healing when used as adjuncts to conventional therapy. Surgical treatment of acute ocular burns includes the debridement of the necrotic tissue, application of tissue adhesives, tenoplasty, and tectonic keratoplasty. Amniotic membrane transplantation is a novel surgical treatment that is increasingly being used as an adjunct to conventional treatment to promote epithelial healing, minimize pain, and restore visual acuity. Various experimental treatments that aim to promote wound healing and minimize inflammation are being evaluated such as human mesenchymal and adipose stem cells, beta-1,3 glucan, angiotensin-converting enzyme inhibitors, cultivated fibroblasts, zinc desferrioxamine, antifibrinolytic agents, antioxidants, collagen cross-linking, and inhibitors of corneal neovascularization.
Summary Improvements in acute burn care have enabled patients to survive massive burns that would have once been fatal. Now up to 70% of patients develop hypertrophic scars after burns. The ...functional and psychosocial sequelae remain a major rehabilitative challenge, decreasing quality of life and delaying reintegration into society. Approaches to optimise healing potential of burn wounds use targeted wound care and surgery to minimise the development of hypertrophic scarring. Such approaches often fail, and modulation of the established scar is continued although the optimal indication, timing, and combination of therapies have yet to be established. The need for novel treatments is paramount, and future efforts to improve outcomes and quality of life should include optimisation of wound healing to attenuate or prevent hypertrophic scarring, well-designed trials to confirm treatment efficacy, and further elucidation of molecular mechanisms to allow development of new preventive and therapeutic strategies.
Burns are a common type of skin injury encountered at all levels of medical facilities from private clinics to core hospitals. Minor burns heal by topical treatment alone, but moderate to severe ...burns require systemic management, and skin grafting is often necessary also for topical treatment. Inappropriate initial treatment or delay of initial treatment may exert adverse effects on the subsequent treatment and course. Therefore, accurate evaluation of the severity and initiation of appropriate treatment are necessary. The Guidelines for the Management of Burn Injuries were issued in March 2009 from the Japanese Society for Burn Injuries as guidelines concerning burns, but they were focused on the treatment for extensive and severe burns in the acute period. Therefore, we prepared guidelines intended to support the appropriate diagnosis and initial treatment for patients with burns that are commonly encountered including minor as well as moderate and severe cases. Because of this intention of the present guidelines, there is no recommendation of individual surgical procedures.
Burns are one of the most common injuries sustained globally. Low- and middle-income countries (LMICs) are disproportionately affected by burn injury morbidity and mortality; African children have ...the highest burn mortality globally. In high-income countries, early surgical intervention has shown to improve survival. However, when applied to burn victims in LMICs, improved survival in the early excision cohort (≤5 d) was not seen. Therefore, we aimed to determine the magnitude of the effect of surgical intervention on burn injury survival.
A retrospective analysis of a prospectively collected data, utilizing the Kamuzu Central Hospital Burn Database from May 2011 to July 2019, was performed. Pediatric patients (≤12 y) were included. Patients were excluded if they underwent surgical intervention for nonacute burn care management. Bivariate analyses stratifying by type of surgical intervention was performed, comparing demographics, burn characteristics, surgical intervention, and patient mortality. Standardized estimates were adjusted using the inverse-probability of treatment weights to account for confounding. Weighted logistic regression modeling was performed to determine the odds of mortality based on if a patient underwent surgical intervention.
During the study, 2364 patients were seen at the Kamuzu Central Hospital, 1785 (75.5%) were children ≤12 y who met inclusion criteria. In the overall cohort, 342 (19.2%) underwent operations, including split-thickness skin graft (n = 196, 57.3%), debridement (n = 116, 33.9%), escharotomy (n = 19, 5.6%), and amputation (n = 1, 0.3%). The surgery cohort was older (4.2 ± 3.1 versus 3.1 ± 2.6 y, P < 0.001) with larger percent total body surface area burns (16%, interquartile range: 10-24 versus 13%, interquartile range: 8-20, P < 0.001) than those who did not have surgery. In the propensity score–weighted logistic regression predicting survival, patients undergoing surgery after burn injury had an increased odds of survival (odds ratio: 5.24, 95% confidence interval: 2.40-11.44, P = 0.003) when compared with patients not undergoing surgery.
In this propensity-weighted analysis, surgical intervention following burn injury increases the odds of survival by a factor of 5.24 when compared with patients not undergoing surgical intervention. Efforts to enhance burn infrastructure to deliver surgical care is imperative to attenuate burn mortality in resource-poor settings.
