Caustic Ingestion in Children: a Systematic Review and Meta-Analysis

The effects of liquid bleach ingestion on children's esophageal and gastric mucosa

OBJECTIVES

The ingestion of caustic substances is currently a significant health concern in pediatric age, being bleach products among the most commonly ingested. The management of children having ingested bleach is currently controversial since scientific data on their degree of toxicity toward the esophageal and gastric mucosa are currently very poor. Therefore, our study aims at comprehensively analyzing the effects of bleach ingestion in children as well as at evaluating patterns of ingestions, clinical symptom development, and endoscopic findings.

METHODS

This prospective observational study was carried out between January 2017 and December 2023 at the Pediatric Department of Santobono Children's Hospital in Naples. Children aged 0-18 years admitted for bleach ingestion were enrolled.

RESULTS

One hundred children with a mean age of 58.7 months were included in the study. Eighty-nine/100 (89%) children had ingested household bleaches (both chlorine- or peroxidase-based) while 11/100 (11%) had ingested homemade or industrial bleaches. The latter were significantly more likely to develop esophagogastric lesions, while children having ingested commercially available household bleaches did not report significant mucosal lesions.

CONCLUSIONS

Our data suggest that the toxicity of commercially available household bleaches on the gastrointestinal tract is very low. Therefore, digestive endoscopy is generally unnecessary in case of household bleach ingestion. Conversely, a timely endoscopic evaluation and close follow-up should be performed in children who ingest homemade or industrial bleaches.

Deer velvet powder-induced antral stricture mimicking infantile hypertrophic pyloric stenosis in a 3-month-old infant: a case report

Antral stricture is a rare cause of gastric outlet obstruction in infants, typically linked to infantile hypertrophic pyloric stenosis (IHPS). We report a case of a 3-month-old male with a 1.5-month history of progressively worsening, nonbilious vomiting. Although initial imaging suggested IHPS, intraoperative findings revealed a sealed antral perforation with dense adhesions, leading to a distal gastrectomy with Billroth I reconstruction. A detailed retrospective history disclosed that the infant had been given deer velvet powder, suspected to have contributed to the perforation and subsequent stricture formation. This novel association highlights potential risks of unregulated supplement use in infants and underscores the need for further investigation.

Accidental Trisodium Phosphate [Na3PO4] (TSP) Ingestion in a Child

BACKGROUND

It is not uncommon for a child to present to the hospital due to accidental ingestions, and oftentimes they are the result of a child accessing household cleaning or home improvement products. Typically, the upper gastrointestinal tract is the site of initial tissue insult and prognosis of these cases depends on a variety of factors, including the ingested substance, injury extent, and assessments and treatments rendered. Possible post-ingestion complications that make management difficult may include mediastinitis, hemodynamic instability, gastrointestinal perforation, erosion and scarring.

CASE

In this case, a 13-month-old boy accidently swallowed Trisodium phosphate [Na3PO4] (TSP), a common household all-purpose heavy-duty cleaner. After ingestion, the patient presented to the emergency department where a multi-disciplinary team-initiated care. Work-up included regular vital checks, electrolyte profiles, blood profiles and an esophagogastroduodenoscopy. He was eventually discharged and scheduled to return for follow-up with esophagram, without long term consequences.

CONCLUSIONS

Although the ingestion of TSP has occurred before, the literature regarding consumption of this specific detergent is negligible. This case provides evidence regarding the treatment and outcome of a paediatric patient who accidentally swallowed TSP and offers guidance in the management of their care.

Short-term and long-term management of caustic-induced gastrointestinal injury: An evidence-based practice guidelines

The Indian Society of Gastroenterology has developed an evidence-based practice guideline for the management of caustic ingestion-related gastrointestinal (GI) injuries. A modified Delphi process was used to arrive at this consensus containing 41 statements. These statements were generated after two rounds of electronic voting, one round of physical meeting, and extensive review of the available literature. The exact prevalence of caustic injury and ingestion in developing countries is not known, though it appears to be of significant magnitude to pose a public health problem. The extent and severity of this preventable injury to the GI tract determine the short and long-term outcomes. Esophagogastroduodenoscopy is the preferred initial approach for the evaluation of injury and contrast-enhanced computed tomography is reserved only for specific situations. Low-grade injuries (Zargar grade ≤ 2a) have shown better outcomes with early oral feeding and discharge from hospital. However, patients with high-grade injury (Zargar grade ≥ 2b) require hospitalization as they are at a higher risk for both short and long-term complications, including luminal narrowing. These strictures can be managed endoscopically or surgically depending on the anatomy and extent of stricture, expertise available and patients' preferences. Nutritional support all along is crucial for all these patients until nutritional autonomy is established.

COVID19 Vaccination Considerations for Pregnant Women: A Systematic Review

Background

Following the coronavirus disease 2019 (COVID-19) pandemic, pregnant women are at a higher risk of developing severe COVID-19 disease. This study investigated whether pregnant women should get vaccinated against COVID-19 or not. Pregnant women in comparison with non-pregnant women.

Materials and Methods

This study was a systematic review that searched the PubMed, Embase, and Scopus databases using the keywords "COVID-19" OR "SARS-CoV-2" OR "Coronavirus Disease" OR "2019-nCoV" AND "pregnancy "OR "pregnant" AND "vaccine" OR "vaccination" from January 2020 to April 2022.

Results

Of the 37 selected studies, 15 (40.50%) declared positive views, 9 (24.30%) had inconclusive views, and 13 (35.20%) opposed vaccination due to a lack of adequate information.

Conclusions

Despite the discrepancies among the studies, one-third of the studies suggested that pregnant women be enrolled in clinical trials to investigate the outcomes of the COVID-19 vaccination on maternal and fetal outcomes. However, the majority of the studies recommended maternal immunization against COVID-19.

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.

Pediatric Acute Respiratory Distress Syndrome and Tracheal Injury in a Patient Requiring Extracorporeal Membrane Oxygenation Following Cement Aspiration: A Case Report

BACKGROUND

Ingestion and aspiration of caustic substances is a common problem in pediatrics and carries the risk of associated aspiration pneumonitis, laryngeal injury, and esophageal injury. Extracorporeal membrane oxygenation (ECMO) has been used to support adults with acute respiratory distress syndrome (ARDS) from aspiration of cement dust, however, literature outlining pediatric management in cases of alkali lung and airway injuries is lacking.

CASE SUMMARY

A 6-year-old boy presented with ARDS from cement aspiration requiring high-pressure ventilation. He had further complications of tracheal injury with subsequent pneumomediastinum secondary to the alkali burn. He required ECMO to facilitate repeat bronchoscopy for cement particle washout and to enable recovery from ARDS and tracheal injury.

CONCLUSION

This case highlights the need to perform early bronchoscopy and gastrointestinal endoscopy for injury assessment and foreign body removal in alkali burns. It also emphasizes the value of ECMO support for respiratory failure and facilitating bronchoalveolar lavage when it is not otherwise tolerated.

Development and validation of a risk prediction nomogram for serious arrhythmias in acute digoxin toxicity among pediatrics: A multicenter study

Digoxin is a cardiac glycoside obtained from the leaves of the foxglove plant, Digitalis lanata. Several studies have described the safety of digoxin including various life-threatening events, notably cardiac arrhythmias. Early identification of high-risk patients and subsequent initiation of the utmost medical care are associated with a better prognosis. The assessment of serum digoxin levels, which is not always convenient, is the only tool used to evaluate the severity of digoxin exposure. However, the feasibility of this tool, particularly in resource-restricted countries, remains unclear. Therefore, the current study aimed to establish and validate a feasible alternative tool, a bedside nomogram, to identify pediatric patients diagnosed with acute digoxin intoxication who are at risk of developing serious arrhythmias. This was a two-phase, multicenter, retrospective study. The prevalence of serious arrhythmias was approximately 17%. Patients diagnosed with serious arrhythmias showed significantly higher serum digoxin, random blood glucose, and potassium levels but lower sodium, magnesium, and hemoglobin levels. Serious arrhythmias were associated with significantly lower P-R intervals, shorter QTc intervals, and more frequent digoxin effects (p < 0.05). The proposed nomogram showed that combining age and initial random blood glucose, sodium, and potassium levels could predict the future incidence of serious arrhythmia with an accuracy of 96.2% (sensitivity = 94.4%, specificity = 96.5%), an area under the curve (AUC) of 0.977, and p < 0.001. Validation of the proposed nomogram yielded an AUC for the nomogram probability of approximately 81%, and the AUC for the predicted probability using the developed model was 98.3%, indicating that both the validated model and the developed nomogram were significant predictors of serious arrhythmia. The utility of using the four-factor nomogram to determine the risk of serious arrhythmia in children exposed to an overdose of digoxin is comparable, if not superior, to the serum digoxin level.

Caustic ingestion leads to pneumonectomy and right colonic interposition, a unique case report

INTRODUCTION

Corrosive ingestion forms serious problem, with various outcomes depending on the time of diagnosis and treatment. We report here a case with rare and dangerous complications.

PRESENTATION OF CASE

A two-year-old girl came to our hospital, complaining of solids' dysphagia. Retrieving her medical history showed that she had ingested a corrosive liquid accidentally. Without knowing the nature of the ingested agent, the local doctor removed it, using nasal gastric tube. This procedure induced vomiting, which in turn led to more damage. She stayed in the area's hospital for 40 days with just supportive treatment. The radiological investigations suggested severe stenosis. The dilation was done, but the patient did not respond after three months of treatment. Therefore, a gastrostomy was done. The esophagus replacement was inevitable, but the parents refused the surgical approach. Three months later, she returned to our hospital complaining of a productive cough. The radiological investigations suggested destruction in the left lung with a high suspicion of tracheoesophageal fistula. The treatment was through a surgical approach by removing the damaged lung tissue and closing the tracheoesophageal fistula. The patient got better after a month of the surgery, which allowed us to replace the esophagus and close the tracheoesophageal fistula.

DISCUSSION

corrosive treatment varies a lot, depending on the patient's situation. Accurate treatment prevents severe and unexpected complications.

CONCLUSION

More stringent instructions should be enacted among medical providers, corrosive agents' producers, and the public to be more careful when dealing with corrosive chemicals.

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.

Endoscopic Grading as a Predictor to Develop Strictures in Corrosive Esophagitis in Children

INTRODUCTION

The incidence of corrosive esophagitis, also known as caustic esophagitis in children, is still increasing in developing countries, according to different clinical reports. Acids and alkalis are, in the same manner, involved in the pathogenesis of corrosive esophagitis in children. The aim of our study was to determine the incidence and endoscopic grading of corrosive esophagitis in a cohort of children from a developing country.

MATERIALS AND METHODS

We performed a retrospective analysis of all pediatric patients who were admitted for corrosive ingestion at Pediatric Clinic II, Emergency Hospital for Children, Cluj-Napoca, over 10 years.

RESULTS

A total of 22 patients consisting of 13 (59.09%) girls and 9 boys (40.91%) were found in the present research. The majority of children lived in rural areas (69.2%). The results of laboratory tests were not well correlated with the degree of the injury. White blood cell counts over 20,000 cells/mm³, an increase in the C-reactive protein level and hypoalbuminemia were noticed only in three patients with strictures. The lesions were associated with increased levels of the pro-inflammatory cytokines, including interleukin (IL)-2, IL-5 and Interferon-gamma. Severe late complications such as strictures have been noticed in children with grade 3A injuries. The endoscopic dilation was done after the six months endoscopy. None of the patients treated with endoscopic dilation required surgical intervention for esophageal or pyloric perforation or dilation failure. The majority of complications (such as malnutrition) were noticed in children with grade 3A injuries. In consequence, prolonged hospitalization has been required. The second endoscopy (done six months after ingestion) revealed stricture as the most common late complication (n = 13, 60.60%: eight patients with grade 2B and five with grade 3A).

CONCLUSION

There is a low incidence of corrosive esophagitis in children in our geographic area. Endoscopic grading is a predictor of late complications such as strictures. Grade 2B and 3A corrosive esophagitis are likely to develop strictures. It is crucial to avoid strictures and to prevent malnutrition.

Initial clinical and laboratory parameters triaging non-pharmaceutical acute pediatric poisoned patients for potential adverse outcomes: a three-year retrospective study

Identifying high-risk pediatric patients with non-pharmaceutical poisoning is crucial to avoid prospective complications and decrease the evident hospital economic burden. Although the preventive strategies have been well studied, determining the early predictors for poor outcomes remains limited. Therefore, this study focused on the initial clinical and laboratory parameters as a triage of non-pharmaceutical poisoned children for potential adverse outcomes taking the causative substance effects into account. This retrospective cohort study included pediatric patients admitted to Tanta University Poison Control Center from January 2018 to December 2020. Sociodemographic, toxicological, clinical, and laboratory data were retrieved from the patient's files. Adverse outcomes were categorized into mortality, complications, and intensive care unit (ICU) admission. Out of enrolled 1,234 pediatric patients, preschool children constituted the highest percentage of the patients investigated (45.06%), with a female predominance (53.2%). The main non-pharmaceutical agents included pesticides (62.6%), corrosives (19%), and hydrocarbons (8.8%), mainly associated with adverse consequences. The significant determinants for adverse outcomes were pulse, respiratory rate, serum bicarbonate (HCO3), Glasgow Coma Scale, O2 saturation, Poisoning Severity Score (PSS), white blood cells (WBCs), and random blood sugar. The cutoffs of serum HCO3 < 17.55 mmol/l, WBCs >8,650 cells/microliter, and PSS > 2 points were the best discriminators for mortality, complications, and ICU admission, respectively. Thus, monitoring these predictors is essential to prioritize and triage pediatric patients who require high-quality care and follow-up, particularly in aluminum phosphide, sulfuric acid, and benzene intoxications.

The comparison of alpha lipoic acid with methylprednisolone and sucralfate in subacute wound healing corrosive esophagus-induced rats: An experimental study

Background

This study aims to compare methylprednisolone frequently used in the therapeutic practices of corrosive esophagus burns, sucralfate, a protective material of mucosal surfaces, and alpha lipoic acid, the most potent antioxidant in a rat model.

Methods

A total of 40 female Sprague-Dawley rats were used in this study. The rats were equally divided into control, alpha lipoic acid, methylprednisolone, and sucralfate groups (n=10). A corrosive esophagus burn was created by using 10% pH:12 sodium hydroxide. No treatment was applied to the control group, and each group was given their own treatment. The treatment was continued regularly until the eighth day, when they were sacrificed. The corrosive esophagus burn lines were removed and tissue sections were stained with hematoxylin and eosin.

Results

The difference in ulceration in the group treated with alpha lipoic acid was significant, compared to the other groups. The most excellent complete epithelialization and complete re-epithelialization were observed in the alpha lipoic acid group. The difference between the groups was significant, with complete re-epithelialization being the lowest in the control and methylprednisolone groups (42.9% and 12.5%, respectively) and the highest in the alpha lipoic acid group (77.8%). In terms of ulceration and re-epithelialization, comparable values were found in the alpha lipoic acid group. The main difference was that the inflammation levels in the sucralfate group were lower and more favorable than the other groups in this period. The glutathione level was significantly higher in the alpha lipoic acid group and decreased the tissue hydroxyproline level.

Conclusion

Alpha lipoic acid reduces esophageal ulceration, severity and prevalence of inflammation, severity and prevalence of fibrosis, decreases tissue damage by increasing blood glutathione level, and also reduces stricture in corrosive esophagus burns in rats.

Utilization of chest tube as an esophagus stent in pediatric caustic injuries: A retrospective study

BACKGROUND

The management of caustic esophageal burns in the pediatric population has changed over the years, while the most optimal management with regards to effectiveness, availability, and cost-beneficent stays controvertible.

AIM

To describe how to utilize a chest tube for esophageal stenting in pediatrics.

METHODS

Data regarding the etiology, treatment, and complications of caustic injury in pediatrics over 10 years was collected retrospectively. Furthermore, data regarding the patient's follow-up who underwent esophageal chest tube (ECT) were collected. The ECT was prepared by carving a narrowed section in the chest tube while maintaining the radiopaque section. The ECT will then be positioned from the cricopharyngeal and exited through the nostril and fixed on the patient's cheek.

RESULTS

During the period of our study, data from 57 patients with an average age of 2.5 years (range 1-12; SD = 1.7) were obtained. The results showed that 89% of esophageal injury was due to alkaline and 9.4% were caused by acidic agents. The treatment methods showed that 29 patients (50.8%) recovered with dilatation alone. In 16 patients (28.06%), the esophageal repair was performed by using the colon, and in 5 patients (8.7%), other surgical methods were used and in 7 patients (12.2%), the ECT stents were used. ECT was inserted in 7 cases with a mean age of 2 (range: 1.5-3) years who were classified as grade IIB or III. Grading was performed by endoscopy assessment on the first day. Antibiotics and corticosteroids were administrated as initial medical management for all patients. ECT implantation was done during the first 8 d for 5 out of 7 cases (mean: 3.8 d). For the 2 patients, ECT was used after 27 (patient 6) d and 83 (patient 7) d. The reason for late stenting in these patients was a postponed referral to our center, in which patient 7 even received 4 dilation episodes before visiting our center. ECT was removed after an average of 44 d in the first 5 patients, while in the other 2 patients (6 and 7) was 2 and 1 wk, respectively. There was no complication related to, or failure of, stent placement. It is worth mentioning that none of the 7 ECT cases required gastrostomy or jejunostomy.

CONCLUSION

The ECT method introduced in our study can be used as a broadly available, economic, and easy-use facility for esophageal stenting, particularly in developing countries and emergency departments which have limited access to modern equipment. Further multicenter studies with higher volume patients are required for further deployment of this method.

Esophageal Stents for the Management of Benign Esophageal Strictures in Children and Adolescents: A Systematic Review of Observational Studies

Little is known about the efficacy and safety of esophageal stents for the management of esophageal strictures in children and adolescents. A systematic review was performed to assess the efficacy and safety of esophageal stents for the management of benign esophageal strictures in children and adolescents. Observational studies related to the examination of esophageal stents in pediatrics were extracted using the original databases by December 2021. We found 18 retrospective and prospective studies with a total of 340 children and adolescents. Overall, our findings show that different therapeutic modalities based on esophageal stents were offered to children and adolescents for various indications, in which most studies reported successful cases, although ineffective claims cannot be ignored. Fully covered self-expandable metal stent, self-expandable metal stent, and silastic esophageal stent were the stent types most used, although different materials and prototypes were reported as well. The number of stents used per patient and the duration of the stenting therapy varied widely (ranging from 1 to 584 days). Such treatments were not standardized because of different factors, such as different tolerance to complications in subjects aged 1 month and 16 years, frequent stent migration requiring removal followed or not by its replacement, different guides provided by each stent manufacturer, and successful healing of esophageal lesions. Different esophageal stents may be a reasonable therapeutic approach for the management of benign esophageal strictures in children and adolescents. We believe that esophagus-sparing methods like stents represent a promising alternative or adjunctive treatment to be considered in pediatrics.

Severe Esophageal Stricture Post Accidental Corrosive Substance Ingestion: A Case Report of Balloon Endoscopic Dilation

Corrosive substance ingestion is a very serious home accident, mostly common in developing countries. It frequently causes esophageal burns in the acute stage and esophageal stricture, stenosis, and even cancer in the chronic stage. Severe cases of caustic esophagitis may require esophageal replacement. We describe a case of balloon endoscopy dilation in a two-year-old girl with a severe stricture of the esophagus resulting from accidental ingestion of a corrosive substance (strong alkaline liquid) which helped the patient preserve the esophagus and prevent esophageal replacement. We describe the clinical complication and development during the treatment.

Indications and Yield of Pediatric Endoscopy in Bahrain: A Tertiary Center Experience

Background and Objectives. Gastrointestinal (GI) endoscopy is a medical field that has been evolving in the last decades. Innovative advances in pediatric endoscopy led to more accurate diagnosis of various GI diseases. This study aimed to assess the appropriateness of endoscopic procedures’ indications and to evaluate the diagnostic and therapeutic yield of pediatric GI endoscopy, considering the limitations to access this facility. Material and Methods. Retrospective, cross-sectional, and analytical chart review was performed for children who underwent GI endoscopy at Salmaniya Medical Complex, Bahrain, from 1995 to 2020. Demographic data, endoscopic indications, and findings were collected and compared. Results. Of 1,111 patients, 1,101 (99.1%) were included in the study. 589 (53.6%) patients were males. Median age at the time of endoscopy was 8 (interquartile range 3, 11) years. 1534 endoscopies were performed (1193 upper GI endoscopies (UGIE) and 341 colonoscopies) in 1296 sessions. The mean number of endoscopies per year was $59\pm 30.9$ procedures with 81.4% reduction noted after coronavirus pandemic ( $P<0.0001$ ). Ratio between UGIE to colonoscopy was 3.5 : 1. Median number of endoscopies per patient was one, ranging from one to eight procedures. 1153 (89%) sessions were diagnostic, and 143 (11.0%) were therapeutic. Main endoscopic indication was chronic abdominal pain (451 (40.9%) patients) followed by upper GI bleeding (302 (27.4%) patients). Overall positive yield was 68.1% (716/1052 procedures). Endoscopic yield varies according to the type of procedure ( $P=0.003$ ). Colonoscopy alone gave a higher yield (82.6%, 38/46 procedures) compared to combined procedures (75.4%, 141/187) and UGIE alone (65.6%, 537/819). Conclusions. This study emphasizes a careful selection of the type of endoscopic procedures, based on the expected endoscopic yield, to diagnose and treat pediatric GI diseases. In patients with chronic abdominal pain, endoscopy should be reserved as a second-line tool to avoid unnecessary use of invasive procedures.

Caustic ingestion in children treated at a tertiary centre in South Africa: can upper endoscopy be omitted in asymptomatic patients?

PURPOSE

Considering that clinical presentation and gastrointestinal tract (GIT) injuries post-caustic ingestion vary in children, this study aims to establish whether a correlation exists between clinical presentation and endoscopic findings.

METHODS

This retrospective study comprised patients referred to a paediatric surgical unit between 2016 and 2018 within 72 h post-caustic ingestion. Data collected included caustic agents ingested, clinical presentation, endoscopic findings and management. Oesophageal injuries were graded according to the Zargar's endoscopic classification and gastric injuries classified as mild to severe.

RESULTS

Fifty patients with a mean age of 2.4 years were managed during the study period. Potassium permanganate (KMNO4) was the most frequently ingested substance in 27 (54%) patients. All 30 (60%) asymptomatic patients had no positive endoscopic findings regardless of clinical signs. Among the symptomatic patients (n = 20), 15 (75%) had oesophageal injuries (p = 0.01). Stridor was associated with a higher grade of oesophageal injury (p = 0.007).

CONCLUSIONS

Clinical signs and symptoms post-caustic ingestion correlated with endoscopic findings in our study. Endoscopy can be safely omitted in asymptomatic patients, including those with isolated staining secondary to KMNO4 ingestion. Symptomatic patients should have an endoscopy performed within 48-72 h of the insult to diagnose injuries.

Sequelae of Corrosive Injury in Children: An Observational Study

Aim

This study aims to determine the sequelae of corrosive ingestion in children.

Methods

A retrospective study was conducted in the Department of Pediatric Surgery at a Tertiary Center. The children presenting between January 2015 and December 2020 with a history of ingestion of caustic agents were included in the study.

Results

A total of 26 children were included in the study. The children with suicidal attempts were significantly older than those who ingested the corrosive agents accidentally (14.2 ± 1.9 years vs. 6 ± 3.3 years; P < 0.01; Student's t-test). Sixteen (62%) children had esophageal strictures, 8 (31%) had pyloric strictures, and a child (4%) had both esophageal and gastric strictures. Eight (31%) children required an initial feeding jejunostomy and 6 (23%) required a feeding gastrostomy as they had significant weight loss on presentation. Eleven (65%) esophageal strictures responded to the dilatation regimen and are symptom-free on follow-up. Three (18%) children with esophageal stricture underwent esophageal replacement. Eight (31%) children had a pyloric stricture and all of them were treated with a modified Billroth I gastro-duodenostomy. The children who presented after 2 months were found to have a significantly increased need for esophageal replacement (3/9 vs. 0/17; P = 0.03; Fischer's exact test).

Conclusion

The corrosive ingestion in children is associated with higher morbidity. The sequelae include esophageal and antro-pyloric strictures. A feeding gastrostomy or jejunostomy was required in more than half of the patients. The children presenting after 2 months of ingestion were associated with an increased need for esophageal replacement.

Evaluation of Pediatric Early Warning System and Drooling Reluctance Oropharynx Others Leukocytosis scores as prognostic tools for pediatric caustic ingestion: a two-center, cross-sectional study

Caustic chemicals are widely distributed in our environment. Exposure to caustic agents is a lifelong problem associated with severe tissue and mucous membrane injuries. In pediatrics, corrosive exposure is the most common cause of nonpharmaceutical exposure presenting to poison control centers. Therefore, this study evaluated the role of the Pediatric Early Warning System (PEWS) and Drooling Reluctance Oropharynx Others Leukocytosis (DROOL) scores as early in-hospital outcome predictors following corrosive ingestion. The current study was a two-center, retrospective, cross-sectional study carried out among pediatric patients diagnosed with acute caustic ingestion during the past 4 years. Most exposure occurred accidentally among boys (59.4%) living in rural areas (51.9%) of preschool age (50% were 2-4 years old). Residence, body temperature, respiratory rate, vomiting, skin and mucosal burns, retrosternal pain, respiratory distress, Oxygen (O2) saturation, Glasgow Coma Scale score, HCO₃ level, total bilirubin level, anemia, leukocytosis, and presence of free peritoneal fluid were significant predictors of esophageal injuries (p < 0.05). DROOL and PEWS scoring were the most significant predictors of esophageal injuries with worthy predictive power, where odds ratio (95% confidence interval (CI)) was 1.76 (0.97-3.17) and 0.47 (0.21-0.99) for PEWS and DROOL, respectively. At a cutoff of < 6.5, the DROOL score could predict esophageal injuries excellently, with AUC = 0.931; sensitivity, 91.7%; specificity, 72.5%; and overall accuracy, 91.3%. At a cutoff of > 6.5, PEWS could significantly predict unfavorable outcomes, with AUC = 0.893; sensitivity, 94.4%; specificity, 71.9%; and overall accuracy, 89.3%. However, PEWS better predicted the need for admittance to the intensive care unit (ICU). Pediatric Early Warning System (PEWS) and Drooling Reluctance Oropharynx Others Leukocytosis (DROOL) are potentially useful accurate scorings that could predict the esophageal injuries and ICU admission following corrosive ingestion in pediatrics.

Corrosive upper gastrointestinal strictures in children: Difficulties and dilemmas

Children constitute 80% of all corrosive ingestion cases. The majority of this burden is contributed by developing countries. Accidental ingestion is common in younger children (< 5 years) while suicidal ingestion is more common in adolescents. The severity of injury depends on nature of corrosive (alkali or acid), pH, amount of ingestion and site of exposure. There are multiple doubts and dilemmas which exist in management of both acute ingestion and chronic complications. Acute ingestion leads to skin, respiratory tract or upper gastrointestinal damage which may range from trivial to life threatening complications. Esophagogastroduodenoscopy is an important early investigation to decide for further course of management. The use of steroids for prevention of stricture is a debatable issue. Upper gastrointestinal stricture is a common long-term sequelae of severe corrosive injury which usually develops after three weeks of ingestion. The cornerstone of management of esophageal strictures is endoscopic bougie or balloon dilatations. In case of resistant strictures, newer adjunctive therapies like intralesional steroids, mitomycin and stents can be utilized along with endoscopic dilatation. Surgery is the final resort for strictures resistant to endoscopic dilatations and adjunctive therapies. There is no consensus on best esophageal replacement conduit. Pyloric strictures require balloon dilatation , failure of which requires surgery. Patients with post-corrosive strictures should be kept in long term follow-up due to significantly increased risk of carcinoma. Despite all the endoscopic and surgical options available, management of corrosive stricture in children is a daunting task due to high chances of recurrence, perforation and complications related to poor nutrition and surgery.

Factors affecting the outcome of endoscopic dilatation in refractory post-corrosive oesophageal stricture in Egyptian children: a single-centre study

BACKGROUND

An important complication of corrosive ingestion is oesophageal stricture. Improvements in endoscopes and accessories have supported an increase in the number of patients who are conservatively treated with endoscopic dilations. In this study, we aimed to detect factors affecting the outcome of endoscopic dilatation for refractory post-corrosive oesophageal stricture.

METHODS

This study was carried out in the Paediatric Endoscopy Unit in the Children's Hospital and included 100 children older than 2 years of age of both sexes who had an established diagnosis of post-corrosive oesophageal stricture on repeated endoscopic dilatation sessions. The duration of the condition was more than 6 months, and dilatation failed to achieve a diameter of 14 mm during the first five sessions at 2-week intervals (refractory), excluding other causes of oesophageal stricture.

RESULTS

Males represented 63% of patients. The mean age of enrolled children was 5.9 ± 2.6 years; 90% of patients ingested an alkaline corrosive substance (potash). The total number of dilatation sessions ranged from 16 to 100, with a mean number of sessions ranging from 37.2 ± 14.9. Fifty-four patients (54%) were well controlled by regular endoscopic dilatation with good clinical and endoscopic outcomes, and no more dilatations were needed.

CONCLUSION

Endoscopic dilation is an effective method for managing refractory post-corrosive oesophageal strictures that require a long follow-up period. There are a lot of factors affecting the outcome.

Caustic Ingestion in Children: 1 Year Experience in 3 Italian Referral Centers

OBJECTIVES

Despite the efforts to reduce the exposure to corrosive household products, caustic ingestion in children is currently a significant medical problem. The aims of the present study were to evaluate the clinical consequences of caustic ingestion and to identify prognostic factors that could concur in driving both diagnostic and therapeutic management.

METHODS

All consecutive children referred for ingestion of a caustic substance from June 2017 to June 2018 were enrolled. Medical records, laboratory and endoscopic findings were reviewed and analyzed.

RESULTS

We enrolled 44 children with caustic ingestion. Alkaline agents were ingested by 26 of 44 (59.1%) patients, whereas acid agents were ingested by 18 of 44 patients (40.9%). Alkaline rather than acid agents were associated with a worse endoscopic score (r: 0.45) and a higher probability of early esophageal stricture occurrence (r: 0.38). The specific risk of the presence of severe esophageal lesions rose progressively with increasing number of symptoms whereas no esophageal injury was found in asymptomatic patients.

CONCLUSIONS

Our data suggest that endoscopic evaluation is mandatory in symptomatic patients to direct therapeutic management, but it could be avoided in asymptomatic patients after accidental ingestion, particularly if the ingestion is only suspected and patients have no oropharyngeal burns.

Effectiveness of the educational interventions on improvement of the performance of burning ward nurses

Introduction — Burning is one of the most accidents with a higher rate of morbidity and mortality. The aim of this study was to investigate the status of nursing cares in the burning ward to improve the quality of nursing service following the education. Methods — An after-before intervention-educational audit study was conducted on burning ward nurses in Iran. The data were collected using a researcher-made checklist based on the Ministry of Health standards with “Yes/No” questions. The data were analyzed using SPSS software version.16 through descriptive statistics and Mc-Nemar nonparametric metric test. Results — The population consisted of 20 nurses working in the burning ward of the Sina Hospital in Tabriz/Iran. Presentation of nursing services was good in terms of the primary care (80.5%) and during hospitalization (83.4%); and it was weak in terms of the secondary care (42.5%). A significant improvement was observed following the educational intervention according to the results of the Mc-Nemar test performed before and after intervention (P<0.001). Conclusion — Audit education improved the nursing secondary cares and follow- up care after patients discharge. It is necessary to hold educational workshops for improving the nurses̓ performance in the other fields.

Polyurethane scaffolds seeded with autologous cells can regenerate long esophageal gaps: An esophageal atresia treatment model

BACKGROUND

Pediatric patients suffering from long gap esophageal defects or injuries are in desperate need of innovative treatment options. Our study demonstrates that two different cell sources can adhere to and proliferate on a retrievable synthetic scaffold. In feasibility testing of translational applicability, these cell seeded scaffolds were implanted into piglets and demonstrated esophageal regeneration.

METHODS

Either porcine esophageal epithelial cells or porcine amniotic fluid was obtained and cultured in 3 dimensions on a polyurethane scaffold (Biostage). The amniotic fluid was obtained prior to birth of the piglet and was a source of mesenchymal stem cells (AF-MSC). Scaffolds that had been seeded were implanted into their respective Yucatan mini-swine. The cell seeded scaffolds in the bioreactor were evaluated for cell viability, proliferation, genotypic expression, and metabolism. Feasibility studies with implantation evaluated tissue regeneration and functional recovery of the esophagus.

RESULTS

Both cell types seeded onto scaffolds in the bioreactor demonstrated viability, adherence and metabolism over time. The seeded scaffolds demonstrated increased expression of VEGF after 6 days in culture. Once implanted, endoscopy 3 weeks after surgery revealed an extruded scaffold with newly regenerated tissue. Both cell seeded scaffolds demonstrated epithelial and muscle regeneration and the piglets were able to eat and grow over time.

CONCLUSIONS

Autologous esophageal epithelial cells or maternal AF-MSC can be cultured on a 3D scaffold in a bioreactor. These cells maintain viability, proliferation, and adherence over time. Implantation into piglets demonstrated esophageal regeneration with extrusion of the scaffold. This sets the stage for translational application in a neonatal model of esophageal atresia.

Overview of caustic ingestion cases at the Children's Hospital of Vilnius University Hospital Santaros klinikos between 2011 and 2018

Background

Although not common, caustic ingestion can cause serious injury and sequelae. Clinical symptoms do not always represent the depth of lesions of the intestinal tract, which makes management of these patients difficult.

Materials and methods

Between 2011 and 2018, we performed a retrospective one-centre study on ingestion of corrosive agents by children. We used ICD-10 codes of X49, X54.X, and T28.2. Cases of eye or skin burns were excluded.

Results

Sixty-five cases were found. Due to a lack of data, we analysed 56 cases. The majority of them were boys (64%); 41% of patients were between 12 and 24 months old. The median age was one year. In 68% of cases, the corrosive substance was alkali: laundry detergent pods and sodium hydroxide accounting for 25% and 14%, respectively. Of the  hospitalised patients and all those admitted to the paediatric intensive care unit (PICU), 78% had oesophagogastroduodenoscopy (EGD), 61% within 24 h after ingestion. The time of EGD was not known for 29% of patients. Nine (29%) had 2nd- or 3rd-degree burns of the oesophagus or the  stomach, one of them did not have any visible changes of the lips and oral mucosa or any symptoms.

Conclusions

Physicians should be suspicious about potential lesions of the gastrointestinal tract when managing caustic ingestion cases. It is recommended to perform EGD for symptomatic children within 24 hours after the accident.

Correlation of 99mTc sucralfate scan and endoscopic grading in caustic oesophageal injury

PURPOSE

To determine a correlation between the 99mTc sucralfate scan and the endoscopy findings in children with caustic oesophageal injury.

METHODS

This is an observational analytic study of children who had both 99mTc sucralfate scan and endoscopy after caustic substance ingestion at our institution in a period between January 2009 and September 2016. The oesophageal injury was classified into low grade and high grade according to the degree of adhesion on 99mTc sucralfate scan and modification of Zargar endoscopic grading.

RESULTS

Out of a total of 197 children, 40 children were identified who had both investigations done on average 26 h post-injury. Low-grade adhesion on 99mTc sucralfate scan was found in 27 children (68%), and all had low-grade Zargar's oesophageal injuries. None of these subsequently developed residual pathology. Thirteen had high-grade adhesion and five of these had high-grade injury on endoscopy. Three (23%) developed oesophageal strictures. Correlation of 99mTc sucralfate and endoscopic findings reached statistical significance with a p value of 0.0014. No morbidity was associated with either the scan or endoscopy.

CONCLUSIONS

We concluded that low-grade sucralfate scan finding has the potential to successfully eliminate the need for invasive endoscopy under general anaesthesia and thereby reducing procedure-related morbidity, hospitalization and associated costs. However, mandatory endoscopy is required in children with high-grade adhesion seen on 99mTc sucralfate scan. This requires confirmation using a larger prospective study.

Accidental aspiration of a solid tablet of sodium hydroxide

Sodium hypochlorite is a corrosive, highly alkaline (pka=7.52) household product. Ingestion of sodium hypochlorite liquid is common, showing toxicity on the oesophagus and stomach. Nevertheless, cases of sodium hypochlorite ingestions in pellet are rare and the management of them is unknown. We report the case of a 65-year-old man who accidentally swallowed a bleach tablet of 3.5 g. Six hours later, the patient developed an aphonia associated with dysponea stage IV, motivating a nasofibroscopy showing glottis and supraglottic necrosis and oedema for which the patient received intravenous steroids, was intubated and then underwent a tracheotomy. After 2 weeks under tracheotomy, local evolution was favourable allowing a removal of the cannula and a return back home.

Corticosteroids for Preventing Caustic Esophageal Strictures: Systematic Review and Meta-analysis

OBJECTIVES

Caustic ingestion can have a complicated clinical course. Corticosteroids are widely used but there is uncertainty about its role in preventing esophageal stricture formation following caustic ingestion. This systematic review and meta-analysis assessed the available clinical evidence regarding the efficacy and safety of corticosteroids for preventing esophageal strictures following caustic injury.

METHODS

We assessed randomized controlled trials (RCTs) that compared corticosteroids versus no corticosteroids in the prevention of esophageal stricture formation following caustic ingestion. We searched the following databases from inception to March 2017: PubMed, Embase, and the Cochrane Central Register of Controlled Trials. Two reviewers retrieved eligible articles, assessed risk of bias, and performed data extraction. The main outcome measure was the prevention of esophageal stricture formation.

RESULTS

The search identified 763 citations. Three RCTs involving 244 participants met the inclusion criteria. There was no benefit of corticosteroids in the prevention of esophageal strictures following the ingestion of caustic materials (risk ratio [RR] = 0.63, 95% CI = 0.29-1.37).

CONCLUSIONS

The available evidence does not support the use of corticosteroids for the prevention of esophageal strictures following caustic ingestion. The overall quality of the evidence is limited because of methodological weaknesses and small sample sizes in the primary studies.

Clinico-epidemiological Characteristics of Corrosive Ingestion: A Cross-sectional Study at a Tertiary Care Hospital of Multan, South-Punjab Pakistan

Introduction Corrosive ingestion is a grave public health problem. It is a medical emergency and shows diverse clinical presentations. The ingestion of corrosive substances has devastating effects on upper gastrointestinal and respiratory tracts and the corrosive injury is associated with numerous life-threatening complications. The present study aims to explore the clinico-epidemiological characteristics of patients of corrosive ingestion presenting at a tertiary care hospital of Multan, Pakistan. Method The target study population consists of all the patients with primary diagnosis of corrosive ingestion who presented to the department of thoracic surgery, Nishtar Medical University Hospital Multan, Pakistan, from January 2016 to December 2017. The follow-up cases and the cases with ingestion of substances other than corrosives were not included in the study. All the included cases were evaluated by detailed history, thorough physical examination and the necessary investigations. The post-cor-rosive tissue damage was classified accord-ing to Zargar's classification system. All the demographic data and other variables were measured and recorded using a Performa. The data were analyzed by using computer program SPSS 21 version. Results The total study population was 206 patients. There were 135 females (65.5%) and 71 male patients (34.5%). Age ranged from 2 to 42 years (mean 23.44 ± 7.19). Only seven cases were found in the age group of 2-7 years. The residents of rural areas showed a slightly increased inclination towards corrosive ingestion. One hundred and ten cases were unmarried (53.4%) while 90 patients were married (43.7%). The incidence of corrosive ingestion was much high in illiterate/less educated patients belonging to the groups of lower socio-economic status. One hundred and ninety-seven patients ingested corrosive substances deliberately with the suicidal intention (95.6%). The acid used as bathroom cleaner and the laundry bleaches were the most commonly used corrosive agents. In 166 cases the corrosive materials were already present at home for domestic purposes (80.6%), but 18 subjects particularly purchased these corrosive substances to commit suicide. The quantity of ingested material ranged between 10 ml and 150 ml with a mean of 42.6 ml ± 33.2. The shortest hospital stay was one day, and the longest one was 60 days. Esophagus and oropharyngeal area were the most common site which sustained the corrosive injury, whereas corrosive injury to duodenum was least frequent (34.5 %). Conclusion Corrosive ingestion is a serious medical problem and it requires a multidisciplinary approach and a good coordination between different medical specialists. Underprivileged teenager females of rural areas are more likely to ingest corrosive materials with suicidal intention. In most of the ingestions, household cleaning products are used. Only the patients with severe corrosive injury should be admitted to intensive care units. Enforcing regulations for the manufacturers of household cleaning products can significantly reduce the incidence of this potentially fatal condition.

Oral Chemical Burns Reported to the Poisons Information Centre in Erfurt, Germany, from 1997 to 2014

Devastating oral burns often followed by lifelong complications can result from ingestion of caustic substances. However, although being one of the most challenging situations in clinical practice, literature data on the epidemiology of oral burns are still scarce. Retrospective analysis of all cases of oral burns after ingestion of corrosive substances reported to the Poisons Information Centre in Erfurt, Germany, from 1997 to 2014 was performed. In total, 482 calls because of oral burns were registered, with no change in the numbers of cases during the years. In the majority of the instances (47%), toddlers were affected, followed by middle-aged adults (33%). In both age groups, the male sex prevailed. Ingestion of corrosive substances with babies, schoolchildren, adolescents, and elderly were much less frequent. In most cases (78%), the injury occurred accidentally and only in 5% of the instances in suicidal intent; 85% of the suicidal attempts were committed by middle-aged adults and 15% by elderly. Main agents involved in oral burns were cleansing agents (37%), remedies (12%), disinfectants (7%), acids or bases (6%), technical fluids (6%), cosmetics (5%), and foods (5%). Mostly, the calls came from emergency department doctors (58%), in 19% laymen were calling from home, and in 18% the calls came from a doctor's office. Most of the injuries occurred accidentally, in the domestic setting and in toddlers, and would have been preventable. Thus, a more comprehensive education of the population, especially of parents, regarding the dangers arising from household chemicals is still needed.
