Esophageal caustic injuries in pediatrics: a sobering global health issue

Clinical evaluation and treatment outcomes of caustic ingestion injuries in Syrian pediatric patients: A retrospective study: Short title: High-dose steroids for pediatric caustic ingestions in Syria

Introduction

Accidental ingestion of caustic agents poses a significant concern in pediatric emergency departments globally. It is a growing public health concern in low-to-middle income countries, which often lack comprehensive data reporting. This study examines high doses of corticosteroid treatment outcomes of caustic ingestion injuries in Syrian pediatric patients, addressing clinical features, and associated variables.

Methods and materials

A retrospective observational study was conducted at University Pediatric Hospital from January 2016 to January 2019. Medical records were reviewed for patients aged <10 years with esophagoscopy-confirmed grade IIa, IIb, or III burns. Data collected included sociodemographics, esophagoscopy results, treatment details, and outcomes.

Results

Among 114 pediatric patients, 76 (67%) were males and 38 (33%) were females. Age groups included <1 year (11%), 1-3 years (39%), 3-5 years (29%), 5-7 years (11%), and >7 years (11%). Alkaline burns accounted for 54% of injuries, acidic for 32%, and other substances for 13%. Complications included bleeding (19%) and psychomotor disability (7%). The most common burn site was the entire esophagus (62%), with 81% having grade II burns. Healing was achieved in 71% of patients with high doses of corticosteroids treatment, and 29% required dilation, with final 92% healing rate.

Conclusion

The use of corticosteroids for esophageal strictures remains inconclusive, demanding further robust research with larger sample sizes and control groups. While our study revealed that high doses of corticosteroids treatment followed by esophageal dilation had a 92% success rate. However, our study demonstrates promising results, methodological limitations and absence of a control group underscore the need for more definitive evidence. Both alkali and acidic ingestion contribute to stricture development.

The Effects of Ellagic Acid on Experimental Corrosive Esophageal Burn Injury

This study aimed to investigate the antioxidant effect of Ellagic acid (EA) on wound healing in sodium hydroxide (NaOH)-induced corrosive esophageal burn injury. The interaction networks and functional annotations were conducted using Cytoscape software. A total of 24 Wistar albino rats were divided into control, corrosive esophageal burn (CEB) and CEB + EA groups. Burn injury was created by 20% NaOH and 30 mg/kg EA was per oral administered to rats. At the end of the 28-day experimental period, Malondialdehyde (MDA) content was measured. Esophageal tissue samples were processed for histological staining. The EA-target interaction network was revealed to be involved in regulating crucial cellular mechanisms for burn wound healing, with epidermal growth factor (EGF) identified as a central mediator. An increase in animal weight in the CEB + EA group was observed in the EA-treated group after CEB injury. Burn injury increased MDA content, but EA treatment decreased its level after CEB injury. Stenosis index, collagen degeneration, inflammation, fibrosis and necrosis levels were increased after CEB injury. EA treatment improved histopathology in the CEB + EA group compared to the CEB group. The expression of EGF was decreased in the CEB group but upregulated in the EA-treated group, suggesting a potential involvement of EA in cellular processes and tissue regeneration. EA, through its antioxidative and tissue regenerative properties, significantly contributes to alleviating the adverse effects of CEB injury, promoting wound healing.

Benzalkonium Chloride Poisoning in Pediatric Patients: Report of Case with a Severe Clinical Course and Literature Review

The use of disinfectants, particularly those containing quaternary ammonium compounds (QUACs), has dramatically escalated globally since the coronavirus disease 2019 pandemic. We report a case that highlights the risks associated with ingesting low-concentration QUAC solutions and emphasize the importance of effective management in resolving severe lesions without sequelae. A 17-month-old boy experienced severe respiratory failure after ingesting a disinfectant containing benzalkonium chloride (BAC). The child was initially treated at a local emergency department and was subsequently transferred to a pediatric poison center. Upon evaluation, the child was found to have grade III-A corrosive esophageal lesions and chemical pneumonitis. Several complications, including massive pneumothorax and candidemia, occurred during the clinical course of the disease. However, with timely medical intervention and appropriate supportive care, the patient completely recovered without any long-term sequelae. The properties of BAC and the comprehensive management approach may have been responsible for the patient's full recovery, despite the potentially life-threatening effects of ingesting disinfectants.

Effectiveness of sucralfate in preventing esophageal stricture in children after ingestion of caustic agents

Ingestion of caustic agents by children is a serious health issue that can affect the patient for the rest of his life. The role of sucralfate in preventing stricture caused by caustic agents is controversial, and limited studies have been conducted in this field. We aimed to investigate the effect of sucralfate on preventing esophageal stricture in children. Sixty children with mean age of 36.69 ± 20.50 months and grade II B esophageal burns due to ingestion of caustic agents were enrolled in the study. In the intervention group, in addition to the usual treatment, sucralfate was administered orally at a dose of 80 mg/kg every 2 h for 3 days. For the control group, only the usual treatment was prescribed. Stricture development was compared between groups based on endoscopic and radiologic findings. Of the 60 patients enrolled in the study, 53 were examined. The incidence of esophageal stricture in the intervention group was significantly lower than in the control group (37% versus 67%, P-value = 0.042). In addition, the odds of esophageal stricture after sucralfate intervention was significantly reduced after adjustment for potential confounders (OR = 0.198, P-value = 0.031).  Conclusions: The results of this study showed that sucralfate may reduce the development of esophageal stricture in children when used to manage IIB esophageal burns due to ingestion of caustic agents. What is Known: • Ingestion of caustic agents by children is a serious health issue that can affect the patient for the rest of his life. • The role of sucralfate in preventing stricture caused by caustic agents is controversial and limited studies have been conducted in this field. What is New: • It seems that sucralfate significantly reduces the incidence of esophageal stricture following the ingestion of caustic agents in children compared to the control group. • We believe that the prognosis may be improved and the risk of stricture formation may be reduced with high doses of sucralfate therapy in grade IIB esophageal injury.

Caregiver burden of families of children with corrosive esophageal injuries

This cross-sectional and descriptive study aimed to determine care burden of families of children with corrosive esophageal injuries. The study involved 112 parents who had children with corrosive esophageal injury. Caregiver's Stress Scale and Reactions to Helping Family Members Scale were used to assess care burden of families. Caregiver's Stress Scale median score was 7.0 [interquartile range 5.0], and Reactions to Helping Family Members Scale median score was 45.0 [interquartile range 14.0]. The burden of family caregivers was thus found to be high. Factors affecting the care burden were found to be child's age, parents' age, child's weight, substance type and pH, surgery status, and number of surgeries. Nurses should consider these factors when advising and educating these families. Additionally, initiatives including support groups should be planned with regard to the needs of these families with a high care burden.

Global Health Challenges: Why the Four S's Are Not Enough

A well-known tenant of global health is the need for the four-S's to be successful in providing care in any context; Staff, Stuff, Space and Systems. Advanced thoracoscopy is slow to gain traction in low- and middle-income countries (LMICs). To our knowledge, no pediatric advanced thoracoscopy had been attempted previously in either LMIC. Therefore, we report the challenges associated with the adoption of the first advanced thoracoscopic procedures in two LMIC hospitals by a visiting surgeon. To further identify aspects of care in promoting the introduction of advanced thoracoscopy, we added a fifth S as an additional category-Socialization. A key to accomplishing goals for the patients as a visiting surgeon, particularly when introducing an advanced procedure, is acceptance into the culture of a hospital. Despite facing significant obstacles in caring for complex thoracic pathology with heavy reliance on disposable and reusable instrumentation provided through donation and limitations in staff such as access to neonatologists and pediatric surgeons, many obstacles have been overcome. In this perspective article, we show that a "fifth S" is also integral-having local surgeons and anesthesiologists eager to learn with acceptance of the visiting surgeon's expertise opens a path towards attempting advanced procedures in limited-resource settings.

The role of endoscopy in caustic ingestion in the pediatric population: experience in a tertiary center

INTRODUCTION

caustic ingestion in children is rare but has potentially serious consequences.

AIM

to analyze the clinical and endoscopic features and the type of caustic ingested in our population.

METHODS

the upper endoscopies performed in this setting, as well as the characteristics of patients and caustics, were analyzed from 2010 to 2018.

RESULTS

fifty-one endoscopies were performed (48 cases of witnessed intake or high suspicion and three with a low suspicion) in patients with a mean age of 2.55 years. Alkali ingestion was more frequent (88.2 %) and 56.9 % of the endoscopies were normal, which was more frequent among those who ingested bleach (72 %). Alkali tended to produce more esophageal injuries (31.1 %) and acids tended to produce esophageal (20 %) and esophageal-gastric injuries (20 %). Four patients developed esophageal stenosis during follow-up.

DISCUSSION

even though more than half of the studies were normal, endoscopy is important in the diagnosis and prognosis of these patients.

Effects of Carvacrol in an Experimentally Induced Esophageal Burn Model: Expression of VEGF and Caspase-3 Proteins

INTRODUCTION

We investigated the therapeutic effects of carvacrol in an experimental esophageal burn rat model with immunohistochemical techniques. Materials and Methods: Three groups were included in this study, composed of eight Wistar albino rats each. The control group was given 1 mL 0.9% (wt/vol) NaCl; esophageal burns were induced in groups 2 and 3 by administration of 1 mL 40% NaOH in the distal 2 cm of the esophagus. The treatment group was administered 75 mg/kg carvacrol in 2 mL 0.9% NaCl for 10 days. After a routine histological examination of the tissues, sections were stained with vascular endothelial growth factor (VEGF) and caspase-3 for immunohistochemical analysis and were examined under a light microscope. Results: In the control group, there were regular cells in the cornified epithelial tissue and cylindrical cells in the basal layer, which faced toward the apical surface in the mitotic phase. The burn group displayed wide degeneration, necrosis, and abundant apoptotic cells in the epithelial tissue as well as intense inflammatory cell infiltration. In the treatment group, there was an increase in mitotic activity in the basal cells of the epithelial layer and degenerative changes, but a preserved epithelial layer and significant cornified structures. The treatment group showed positive caspase-3 expression in some apoptotic cells within the epithelial layer and in connective tissue, and there were only a small number of degenerated cells in the muscle layer. Additionally, in the treatment group, VEGF expression was evident in small numbers of inflammatory cells in the papillary region of the epithelium, and in dilated vascular endothelial cells. Conclusions: Carvacrol may contribute to a reduction in fibrosis by decreasing inflammation and preventing cell apoptosis.
