UNASSIGNED: To evaluate the prevalence and clinical characteristics of limbal stem cell deficiency (LSCD) in the setting of a tertiary referral cornea practice at an academic center.
UNASSIGNED: A retrospective chart review was performed to identify all unique medical record numbers (MRNs) presenting to a single cornea specialist (JHH) at the University of Minnesota during calendar years 2019 and 2020. Records were queried and confirmed for a diagnosis of LSCD. Clinical characteristics of identified patients, including demographics, etiology of LSCD, severity of LSCD, treatment, and best corrected visual acuity (BCVA) at final follow-up, were documented.
UNASSIGNED: In total 1436 unique MRNs were identified over the study period. There were 61 individuals (91 eyes) diagnosed with LSCD, resulting in a prevalence of 4.25% (95% CI, 3.33-5.42). Of 91 eyes, 60 eyes were bilateral (65.9%). Among all eyes, ocular surface burns were the most common etiology (18.7%) followed by iatrogenic or medicamentosa (15.4%). There were 51 eyes (56.0%) that underwent some form of transplantation. The median BCVA at final follow-up was Snellen 20/80 (range 20/20 to no light perception).
UNASSIGNED: The prevalence of LSCD found at a cornea subspecialty tertiary referral center in our study was much higher than previously reported prevalence rates. This may reflect referral bias and potential underdiagnosis of LSCD in practices outside of subspecialty referral centers. The high prevalence rate in our study also suggests that LSCD patients are concentrated in subspecialty referral practices, with many having high morbidity disease. This constitutes a major health burden for these practices.

Thermal injury to the pharyngeal structures is uncommon, and clinicians generally attribute these injuries to consuming hot foods or liquids. While thermal injuries have been reported with the ingestion of hot substances, thermal injuries from vape pens have not been widely described in the literature. We present a case of a 35-year-old male who presented to the emergency department (ED) with oropharyngeal burns after utilizing a vape pen that malfunctioned. The patient had visible burns on his uvula, as well as on the soft and hard palate. Additionally, he had symptoms of difficulty swallowing and a hoarse voice, which raised concerns about a possible deeper airway or lung injury. The patient required a flexible nasopharyngolaryngoscopy by a head and neck surgeon, which revealed mild edema and erythema of the epiglottis and the arytenoids. The patient was admitted to the hospital overnight for observation and treatment with analgesia and dexamethasone. The following morning, the patient\'s symptoms had improved. The repeat nasopharyngolaryngoscopy showed improvement in the swelling of the epiglottis and arytenoids, and the patient was deemed stable for discharge. This case brings attention to the variety of injuries possible from e-cigarette use and the importance of prompt management of oropharyngeal thermal injuries.

Ocular burns can have three origins: chemical (by acid or alkaline agents), luminous (by ultraviolet radiation) or thermal. We report the cases of eight patients with ocular burns (3 thermal and 5 chemical). Of these, one patient had a grade 2 burn according to the Dua classification, two had grade 3 damage and one had grade 4. One patient had grade 3 damage in the right eye and grade 4 in the left eye. Anterior segment optical coherence tomography (AS-OCT) was performed in two patients, showing corneal de-epithelialization, corneal thickening and a hyper-reflective line in the posterior stroma. All patients received medical treatment with topical antibiotics, topical corticosteroids, cycloplegics and wetting agents. Five patients had outpatient treatment with clinical improvement. Three patients were hospitalized, one of whom received an amniotic membrane graft (AMG), one had an AMG followed by a transfixing keratoplasty (TK), and the other is scheduled for a TK. Ocular burns are associated with significant functional risk, warranting prompt and effective management.

Burn injuries pose significant challenges to both patients and healthcare systems globally. This retrospective observational study, conducted at the burn center in a tertiary care hospital in Rawalpindi, Pakistan, aimed to delineate the patterns of burn injuries and correlate them with demographic and clinical presentations. A total of 99 patients were included, with 54 males and 45 females, ranging in age from three months to 70 years. Flame burns were the most common type (n=69), with the majority being accidental (n=87). Limbs were the most frequently affected body parts (n=32), often with lesser-degree burns (n=28). Notably, self-inflicted injuries were predominantly observed in males (n=7), while assault cases were more common in females (n=4). Statistical analysis revealed significant associations between the degree of burn and the body parts affected, as well as between the mode of injury and the affected body parts. Burn injuries due to assault or self-infliction tended to have higher morbidity rates, often resulting in fatalities. Additionally, the cause of burn injury showed significant associations with the affected body parts, with contact and electric burns affecting limbs and chemical burns mainly affecting the head and face. These findings underscore the need for targeted burn prevention programs, emphasizing first aid education and addressing specific risk factors in high-risk groups and settings. By implementing preventive strategies and evaluating their effectiveness, the burden of burn injuries can be reduced, leading to improved patient outcomes and quality of life.

Thermal burn injuries can result in significant morbidity and mortality. The combination of ethanol intoxication with thermal burn injury results in increased morbidity through an exaggerated inflammatory response involving many organs. Recent studies have linked involvement of the lipid mediator Platelet-activating factor (PAF) in the pathology associated with intoxicated thermal burn injury (ITBI). The present studies tested the roles of PAF and the elevated levels of subcellular microvesicle particles (MVP) generated in response to ITBI in the subsequent multi-organ toxicity. First, thermal burn injury of HaCaT keratinocytes preincubated with ethanol resulted in augmented MVP release, which was blocked by inhibiting the PAF-generating enzyme cytosolic phospholipase A2 and the PAF receptor (PAFR). Second, ITBI of mice resulted in increased pro-inflammatory cytokine production and neutrophilic inflammation in multiple organs which were not present in mice deficient in PAFRs nor the MVP-generating enzyme acid sphingomyelinase (aSMase). Moreover, the increased bacterial translocation from the gut to mesenteric lymph nodes previously reported in murine ITBI was also dependent upon PAFR and aSMase. MVP released from ITBI-treated keratinocytes contained high levels of PAFR agonistic activity. Finally, use of topical aSMase inhibitor imipramine following ITBI attenuated the widespread organ inflammatory response of ITBI, suggesting a potential therapeutic for this condition. These studies provide evidence for PAF-enriched MVP generated in skin, which then act upon the gut PAFR resulting in bacterial translocation as the mechanism for the multi-organ dysfunction associated with ITBI. Inasmuch as aSMase inhibitors are widely available, these studies could result in effective treatments for ITBI.

Prompt management of burn-related globe trauma can prevent long term complications. Delays in diagnosis may occur when globe trauma is associated with life-threatening injuries. We aimed to improve the understanding of the epidemiology, acute assessment and management of burns-related globe and adnexal trauma admitted to two trauma centres in Sydney, Australia.
Admitted patients with burns-related globe and/or adnexal trauma were retrospectively reviewed at Royal North Shore Hospital (RNSH) and Royal Prince Alfred Hospital (RPAH) between January 2015 and December 2019. The International Classification of Disease, Tenth Revision codes was used to search and identify patients. Medical records were reviewed to extract data on demographics, injuries, ocular examination and ophthalmology involvement.
Over the 5-years, 101 patients with globe and/or adnexal burns-related trauma were admitted to RNSH or RPAH. Median age was 37years. Most patients were male (76%) and were injured while at home or work (74%). Patients with chemical exposure were more likely to have globe trauma (100% vs 72%, p < 0.001) and severe globe trauma (54% vs 32%, p = 0.028). On initial review by emergency staff, 14 patients were not referred to ophthalmology, of these there were 2 patients where the diagnosis was delayed.
Globe trauma is common in patients with chemical exposure. Thorough ocular assessment within the acute setting is vital to diagnose globe trauma. We investigated hospitals with specialised burn staff, further research is required to understand the management of globe trauma in hospitals without such resources.
Chemicals in household-products can cause severe globe trauma. Globe trauma can occur alongside large burns leading to delay in its diagnosis and management. Ophthalmology can assist in the early diagnosis and management of globe trauma.

Organ dysfunction and failure increase the morbidity and mortality following major burn. Alteration of liver morphology and function is common following major burns; however, it has not received much attention. In this study we have assessed the impact of thermal burn on liver in relation with mortality.
55 patients (33 female and 22 males) with TBSA 10-90% and age ranged from 18 to 75 years were included. A bed side serial ultrasonography to assess the volume of liver and liver function tests was done on the 2nd, 9th and 16th day following burn. Baseline demographic and clinical information such as age, gender, burn size and outcome of patient were also collected.
8 patients died during 2nd week following burn and 47 survived. The mean TBSA for survivors was 37% and for non survivors 80%. Mean liver volume in survivors steadily decreased from 1693.70 cm3 to 1631.31 cm3 over 3 weeks. Mean liver volume in non- survivors steadily increased from 1855.88 cm3 to 2028.50 cm3 over 2 weeks. Liver function test in survivors steadily improved while in non survivors it deteriorated over 2 weeks.
There is a correlation between altered liver morphology and function with mortality among severely burnt patients however liver volume did not show statistical significance. A decreasing trend of liver dysfunction parameters and hepatomegaly following burn is associated with good prognosis.

Decreased bone mineral density (BMD) is a common condition after a burn with significant complications that would be a global health problem. Also, balance can further worsen due to burning complications. Therefore, this study aims to analyze the additive effects of selected Qigong training exercises for 2 months to the standard physiotherapy regimen on bone mineral density and balance control post-thermal burn injuries.
110 participants (75 males and 35 females), aged 25-50, with deep second and third-degree thermal burns affecting the trunk and lower extremities, and a total body surface area (TBSA) of 30-45%, allocated randomly into two equal groups of 55. Group A has Qigong training along with its standard physiotherapy regimen, and the control group (Group B) has only a standard physiotherapy regimen. For eight weeks, the interventions were used four times a week. The bone mineral density (BMD), T-score of the lumbar spine, the overall stability index (OSI), and the dynamic limits of stability (DLOS) were assessed pre-intervention and after eight weeks of intervention.
A two-way mixed MANOVA showed that there was a significant increase in BMD, T-score, and DLOS and a significant decrease in OSI in a favor of the Qigong training group after eight weeks of treatment compared with that of the control group. Both groups showed a significant improvement in BMD, T- score, DLOS, and OSI post-treatment compared with that at the baseline. There were statistical significances in the favor of the Qigong training group after eight weeks of treatment (P < 0.001).
In patients with repaired second and third-degree thermal burns of the trunk and lower legs, Qigong training activities combined with a standard physiotherapy regimen for 2 months were more helpful in increasing bone mineral density and improving balance control than the standard physiotherapy regimen alone.

Worldwide, thermal burn is the leading etiological type of burn injury accounting for 86% of burn injuries requiring admissions. Flame, Scald, and contact burn are the leading causes of thermal burn. Changes in the sociodemographic characteristics of societies have led to alterations in the epidemiology of burn. An understanding of such changes in the epidemiology of burn is essential in formulating and executing adequate burn prevention programs. We sought to establish the current trend in the etiology, gender distribution, age, occurrence of inhalation injury, burn surface area, burn depth, and mortality rate of thermal burns at Ibadan. This was a retrospective study carried out between January 2013 and December 2022. Thermal burns constitute 92% of burn injuries. The male-to-female ratio was 1.4:1. There were 265 (45%) patients in the pediatric age group and 323 adults (55% of the patients). The proportion of flame, scald, and contact burns were 378 (58%), 203 (32%), and 14 (2%), respectively. Flame burns resulting from liquified petroleum gas (LPG) explosion show a rising trend, with a decline in flame burns from kerosene (P < .001). One hundred and ninety (32%) patients had inhalation injury. The overall mortality was 19% (N = 114). Kerosene flame, 38% (17 of 45 patients), and LPG, 32% (41 of 130 patients), were the most lethal causes of flame injuries (P < .043). The study shows the increasing contribution of LPG to the etiology of thermal burn injuries. Burn prevention programs should target safe use of LPG stoves and cylinders.
