A platelet count of less than 150,000 per microliter of blood is called thrombocytopenia. Platelet count monitoring is essential in the care of burn patients. The aim of this study was to evaluate platelet count in groups of patients with different percentage of burns on the body surface and its relationship with the severity of burns and mortality. This retrospective descriptive cross-sectional study was performed on patients admitted to Shahid Motahari Hospital over a period of six months. The study was conducted on burn patients who were admitted to the hospital on the first day after injury. Patients were divided into two groups of with or without thrombocytopenia in the first week. Demographic information and treatment information about the patients were recorded. SPSS V.26 software was used for the statistical analysis of data. In this study, the prevalence of thrombocytopenia in the first week after burns was 36%. The variables of age, sex, duration of hospitalization, burn agent, percentage of burns and use of silver sulfadiazine ointment were significantly different in the two groups of patients. The group without thrombocytopenia had a mortality rate of 5.1%, while the group with thrombocytopenia had a rate of 32.2%. Based on the results of this study, thrombocytopenia is significantly associated with mortality in burn patients. Furthermore, the results of this study indicate that age, sex, burn agent, percentage of burns, and the use of silver sulfadiazine ointment have a clear impact on the thrombocytopenic status of patients.
La thrombopénie est définie par un compte plaquettaire <150 000/mm3, et la surveillance de la numération plaquettaire (NP) fait partie de la biologie de routine chez les brûlés. Cette étude a pour but l’évaluation de la cinétique de la NP chez des brûlés sur des surfaces variables et sa relation avec la sévérité de la brûlure et la mortalité. Il s’agit d’une étude rétrospective auprès de patients admis dans les 24h suivant leur brûlure dans le CTB de l’hôpital Shahid Motahari durant une période de 6 mois. Nous avons comparé ceux ayant subi une thrombopénie dans la première semaine aux autres (démographie, traitement), les statistiques ayant été réalisées avec SSPS version 26. La prévalence de la thrombopénie précoce est de 36%. Âge, sexe, cause, surface brûlée, recours à la sulfadiazine argentique et durée d’hospitalisation étaient différents entre les deux groupes. La mortalité des patients thrombopénique était de 32,2% VS 5,1%. Elle est significativement associée à la mortalité. L’âge, le sexe, la cause, la surface et la sulfadiazine argentique sont associées à la survenue de thrombopénie.

This literature review will provide a critical narrative overview of the highlights and potential pitfalls of the reported animal models for limbal stem cell deficiency (LSCD) and will identify the neglected aspects of this research area. There exists significant heterogeneity in the literature regarding the methodology used to create the model and the predefined duration after the insult when the model is supposedly fully fit for evaluations and/or for testing various therapeutic interventions. The literature is also replete with examples wherein the implementation of a specific model varies significantly across different studies. For example, the concentration of the chemical, as well as its duration and technique of exposure in a chemically induced LSCD model, has a great impact not only on the validity of the model but also on the severity of the complications. Furthermore, while some models induce a full-blown clinical picture of total LSCD, some are hindered by their ability to yield only partial LSCD. Another aspect to consider is the nature of the damage induced by a specific method. As thermal methods cause more stromal scarring, they may be better suited for assessing the anti-fibrotic properties of a particular treatment. On the other hand, since chemical burns cause more neovascularisation, they provide the opportunity to tap into the potential treatments for anti-neovascularisation. The animal species (i.e., rats, mice, rabbits, etc.) is also a crucial factor in the validity of the model and its potential for clinical translation, with each animal having its unique set of advantages and disadvantages. This review will also elaborate on other overlooked aspects, such as the anaesthetic(s) used during experiments, the gender of the animals, care after LSCD induction, and model validation. The review will conclude by providing future perspectives and suggestions for further developments in this rather important area of research.

Thermal burns produce tissue damage, which eliminates the protective role of tissue. Due to the extensive tissue damage from severe burns, an overactive immune response occurs. Furthermore, this raises the possibility of getting sepsis, a condition in which a bacterial infection spreads throughout the body rather than only in the area of the injury or localized infection. To determine the compounds of Ajwa dates have the potential as an anti-inflammatory and antibacterial agent in infectious thermal burns. The research method used the Preferred Reporting Items for Systematic Review and Meta-Analyses guideline. Various references were collected from the online database Google Scholar and PubMed including reports, journals, and all references mostly published no more than the past 10 years. This systematic review revealed 16 research articles that were pertinent. Polyphenolic substances such as flavonoids, glycosides, and phenolic acids were found in ajwa dates. Specified polyphenol chemicals have the ability to interact with one or more immune cell receptors, moving intracellular messages and influencing the host\'s immunological response. Ajwa dates\' polyphenol acts as an anti-inflammatory agent in severe burns by inhibiting the expression of pathogen-associated molecular pattern receptors, controlling transcription factors, and changing the phenotype of macrophage cells, among other ways. The bacterial activity and immune response regulation of Ajwa dates, on the other hand, also serve as an antibacterial agent directly. The polyphenol compounds in Ajwa dates have the potential to operate as an anti-inflammatory and antibacterial agent in infected thermal burns.

UNASSIGNED: To study and compare the demographic and clinical profile of acute ocular burns (AOB) in children and adults.
UNASSIGNED: This retrospective case series included 271 children (338 eyes) and 1300 adults (1809 eyes) who presented to two tertiary eye care centers within one month of sustaining AOB. Data regarding demographics, causative agents, severity of injury, visual acuity (VA), and treatment were collected and analyzed.
UNASSIGNED: Males were more commonly affected particularly among adults (81% versus 64%, P < 0.00001). Among children, 79% sustained domestic injuries, whereas 59% of adults had work-place injuries (P < 0.0001). Most cases were due to alkali (38%) and acids (22%). Edible lime (chuna, 32%), superglue (14%), and firecrackers (12%) in children, and chuna (7%), insecticides, lye, superglue (6% each), toilet cleaner (4%) and battery acid (3%) in adults, were the main causative agents. The percentage of cases with Dua grade IV-VI was greater in children (16% versus 9%; P = 0.0001). Amniotic membrane grafting and/or tarsorrhaphy were needed in 36% and 14% of affected eyes in children and adults, respectively (P < 0.00001). The median presenting VA was logMAR 0.5 in children and logMAR 0.3 in adults (P = 0.0001), which improved significantly with treatment in both groups (P < 0.0001), but the final VA in eyes with Dua grade IV-VI burns was poorer in children (logMAR 1.3 versus logMAR 0.8, P = 0.04).
UNASSIGNED: The findings clearly delineate the at-risk groups, causative agents, clinical severity, and treatment outcomes of AOB. Increased awareness and data-driven targeted preventive strategies are needed to reduce the avoidable ocular morbidity in AOB.

Many studies demonstrate that being burned has both physical and psychological sequelae that affect quality of life. Further, these effects may be more prevalent in some regions and populations. We sought to access the unbalanced distributions and temporal trends concerning the health burden of thermal burns.
Data were collected from the Global Burden of Disease Study 2017, and the disability-adjusted life year (DALY)1 was used as a measure of health burden. Linear regression was used to evaluate the relationship between the age-standardized DALY rate and socio-demographic index.2 Joinpoint regression analysis and comparison line charts were all applied to assess the temporal trends of burns.
The age-standardized DALY rate of global thermal burns decreased by 43.7%, from 197 (95% CI: 152-228) per 100,000 in 1990 to 111 (95% CI: 93-129) per 100,000 in 2017. The burden was borne mainly by children 1-4 years of age and people over 80 years. Socio-demographic index was negatively correlated with the age-standardized DALY rate. In low-middle and low socio-demographic index regions, the decreasing trends were slower than other regions with an average annual percentage change of -2.1% (95% CI: -2.2 to -2.0) and -2.1% (95% CI: -2.1 to -2.0), respectively. Among six geographical regions, Africa presented the highest age-standardized DALY rates of 352 (95% CI: 275-410) per 100,000 in 1990 and 208 (95% CI: 175-236) per 100,000 in 2017, and also the slowest average decreasing trend, with an average annual percentage change of -1.9% (95% CI: -2 to -1.8).
The global burden of thermal burns shows a downward trend from 1990 to 2017, and regions with lower socio-demographic index and Africa show greater burdens and smaller downward trends.

The aim of the study was to evaluate the efficacy and safety of the Collost bioplastic material in the treatment of borderline and mosaic burns.
UNASSIGNED: We conducted a prospective multicenter study, which included 94 patients aged 1 to 12 years with thermal skin burns (grade II-III by ICD-10). Patients were divided into four groups. In groups 1-3, various forms of the Collost bioplastic material were used (group 1 - 7% gel, group 2 - membranes, group 3 - powder) in combination with hydrocolloid dressings containing Ag+ ions. Patients of the control group (group 4) underwent the traditional local conservative treatment using hydrocolloid dressings alone. Concomitant therapy was similar in all of the participating centers. The total follow-up period was 4 weeks from the date of burn injury.
UNASSIGNED: On day 14, there were 23 cases (92%) of complete epithelization in group 1, 13 cases (68.4%) - in group 2, 21 cases (78%) - in group 3, and 9 cases (39.1%) - in group 4. The data from groups 1 and 3 significantly differed from those in control (p<0.05). The epithelialization of the burned skin in the Collost groups (7% gel and powder) was on average one week faster compared to the control.
UNASSIGNED: The Collost bioplastic material (in the form of gel or powder) in combination with hydrocolloid dressings can be a functional and inexpensive alternative to autografts in the treatment of borderline and mosaic burns.

Experimental burn models are essential tools for simulating human burn injuries and exploring the consequences of burns or new treatment strategies. Unlike clinical studies, experimental models allow a direct comparison of different aspects of burns under controlled conditions and thereby provide relevant information on the molecular mechanisms of tissue damage and wound healing, as well as potential therapeutic targets. While most comparative burn studies are performed in animal models, a few human or humanized models have been successfully employed to study local events at the injury site. However, the consensus between animal and human studies regarding the cellular and molecular nature of systemic inflammatory response syndrome (SIRS), scarring, and neovascularization is limited. The many interspecies differences prohibit the outcomes of animal model studies from being fully translated into the human system. Thus, the development of more targeted, individualized treatments for burn injuries remains a major challenge in this field. This review focuses on the latest progress in experimental burn models achieved since 2016, and summarizes the outcomes regarding potential methodological improvements, assessments of molecular responses to injury, and therapeutic advances.

Thermal burns of the oral cavity usually arise from ingestion of hot foods or beverages. A 38-year-old female patient presented with two painful ulcerative erythematous patches of the palate. The patient was consulted on the same day lesions appeared. Medical history was unremarkable. Clinically significant self-inflicted injuries may result in wide ulcers in the mouth and usually do not take less than 2 weeks to heal, whereas our patient, treated with low-level laser therapy, had a complete response in day 4, after 2 days of treatment. The fact that multiple lesions were present signaled against the World Health Organization exclusion diagnosis of erythroplakia for red patches. A traumatic ulcer, regardless of its cause of origin, usually heals within 2 weeks, after the source of injury is resolved. A thermal burn in the oral cavity usually takes longer than that to heal, but whenever this time frame is not respected, the suspicion of a potentially malignant disorder should always arise, and a biopsy should be performed. The present case showed two painful thermal burns with great results in terms of speeding up the relieve of symptoms and healing time with soft laser as opposed to the traditional treatment with oral topical corticosteroid.

Comparative studies of human tissue damage caused by burns are challenging because precise information regarding the temperature, time, and duration of the exposure is often missing. Animal models cannot be fully translated to the human system due to interspecies differences in cutaneous tissues. We used a human composite tissue model to compare tissue damage caused by thermal burns with different dynamics. Equal subcutaneous/cutaneous composite tissue samples from six donors were first exposed to either preheated steel (100 °C) or a precision flame burner (300 °C) and were then maintained in vitro for seven days. Histological and immunohistochemical analyses revealed that flame burns instantly caused deep and stable damage to the subcutaneous tissue, which stayed constant for seven days. By contrast, contact burns inflicted tissue damage that was initially superficial but then expanded deeper into the adipose tissue. This spatiotemporal expansion of tissue damage was essentially accompanied by macrophage and fibroblast activation, which points towards inflammation resolution and wound healing. Our study suggests that thermal differences in burns directly influence the course of tissue damage, the cellular response and, consequently, the likely dynamics of repair processes days after burn injuries.

During magnetic resonance imaging, thermal burns are a potential cause of injury. We experienced a rare case of magnetic resonance imaging burn injury caused by jogging pants. The list of materials of the jogging pants did not indicate any metal. However, light, thin metal fibers were used. Changing to suitable magnetic resonance imaging-compatible clothing is important before undergoing magnetic resonance imaging. To minimize the risk of magnetic resonance imaging burns, it is necessary to increase staff awareness and communicate and comply with pretreatment safety checks.
