Fatal corrosive ingestion: A study from South and South-East Delhi, India (2005-2014)

Rabbi NA, Pradeeptha S, Kumar S, Selvaraj B, Gunasekaran K. Deliberate self-poisoning and harm: A meticulous quest of methods in vogue

Background:

Deliberate self-poisoning and harm (DSPH) is an unabating problem with a wide variation in the methods used across the world. Hence, this study was conducted to understand the current spectrum of methods used for DSPH by patients in our geographic locality and catchment area with special emphasis on newer compounds and drugs used.

Methods:

This retrospective study included patients presenting with DSPH to the emergency department (ED) between January 2017 and December 2018.

Results:

This study included 1802 patients, with a mean age of 32 ± 12.7 years. Of the patients, 85% were in the young to middle age group (16–45 years). Agrochemicals (n = 604, 33.5%), drugs (n = 498, 27.6%), plant toxins (n = 150, 8.3%) and rodenticides (n = 145, 8%) were the predominantly used compounds. The major emergency resuscitation procedures required in the ED were intubation (n = 321, 18%), vasopressor support (n = 73, 4%) and cardiopulmonary resuscitation (n = 27, 1.4%). A quarter (23.2%) was discharged stable from the ED, whereas a further 56.5% were discharged stable after hospital admission. The in-hospital mortality rate was 3% (n = 47). Multivariate logistic regression analysis showed rodenticides (odds ratio (OR): 22.32; 95% confidence interval (CI): 8.05–61.88; P = 0.005) and plant poisons (OR: 23.92; 95% CI: 8.95–63.94; P = 0.005) to be the independent predictors of mortality.

Conclusion:

DSPH is prevalent in the highly productive young age group. Agrochemical ingestion and drug overdose are the most common methods used, whereas rodenticide and plant poisoning are associated with significant mortality.

The Diagnosis of a Case of Household Cleaner Fatality

Household cleaners are an unavoidable entity in our routine domestic life. They are available either in company-labeled bottles or locally made unlabeled bottles especially in the developing countries. In this report, we are discussing a case of fatal ingestion of household cleaner, which was stored in an unlabeled bottle. The deceased developed features of gastrointestinal irritation, such as vomiting and pain in throat and abdomen. He also had features of aspiration such as cough and chest crepitation. Finally, he developed metabolic acidosis, gastric perforation, respiratory failure, and died within a day. The autopsy features such as teeth discoloration, corrosion of mouth and lips, and histopathological findings helped us in concluding that the ingredients contained some corrosive mineral acid. This case highlights the importance of histopathological examination of viscera in alleged cases of household cleaner poisoning where toxicological analysis of viscera gives negative results.

Corrosive injury of the upper gastrointestinal tract: the evolving role of a radiologist

Corrosive injury is a devastating injury which carries significant morbidity. The upper gastrointestinal tract is predominantly affected with severity ranging from mild inflammation to full thickness necrosis which may result in perforation and death. Among the complications, stricture formation is most common, causing dysphagia and malnutrition. Endoscopy has a pivotal role in the diagnosis and management, with a few shortcomings. Imaging has an important role to play. Besides radiography, there is an increasing role of CT scan in the emergency setting with good accuracy in identifying patients who are likely to benefit from surgery. Further, CT scan has a role in the diagnosis of complications. Oral contrast studies help in assessing the severity and extent of stricture formation and associated fistulous complications in the subacute and chronic phase. The scope of intervention radiology for this condition is increasing. Fluoroscopy-guided balloon dilatation, drainage of collections or mucoceles, endovascular embolization of point bleeders, placement of feeding jejunostomy and image-guided biopsy are among the procedures that are being performed. Through this review we aim to stress the role the radiologist plays in the diagnosis and follow-up of these patients and in performing radiological interventions. Besides this, we have also highlighted few salient points to help understand the pathophysiology and management of such injuries which is paramount to ensure a good long-term outcome.
