Insights
Button battery ingestion in children can cause serious esophageal damage. Prompt diagnosis and treatment are crucial to prevent severe complications and ensure positive outcomes.
Area of Science:
- Pediatric Gastroenterology
- Emergency Medicine
- Otolaryngology
Background:
- Button batteries (BB) are common household items that pose a significant ingestion risk to young children.
- Esophageal lodgement of ingested button batteries can lead to severe mucosal injury and complications.
Observation:
- Two pediatric cases of button battery ingestion with esophageal lodgement are presented.
- Case 1: Timely diagnosis and treatment resulted in no sequelae.
- Case 2: Delayed diagnosis led to both early and late complications.
Findings:
- The critical importance of prompt diagnosis and appropriate management of suspected button battery ingestion in children is demonstrated.
- Delayed intervention significantly increases the risk of severe esophageal damage and long-term adverse effects.
Implications:
- Highlights the need for heightened awareness among parents and healthcare providers regarding the dangers of button battery ingestion.
- Emphasizes the necessity of rapid diagnostic and therapeutic protocols for esophageal button battery foreign bodies in pediatric patients.
- Underscores the potential for severe morbidity and mortality if button battery ingestion is not managed effectively.
Abstract:
We report two cases of oesophageal lodgement of ingested button batteries (BB) in young children. In one case the diagnosis and subsequent treatment was made in a timely fashion and the patient suffered no sequelae. In the second case there was a delay in diagnosis and the patient subsequently suffered both early and late complications. The purpose of this report is to highlight theingestion importance of the correct management of suspected BB ingestion.

Multiple Voltage Sources
In series, the positive terminal of one battery is connected to the negative terminal of another battery. Hence, the voltage of each battery is added to give the net voltage, which is increased because each battery boosts the electrons that enter it. The same current flows through each battery because they are connected in series.

Voltaic/Galvanic Cells
Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
Charging Conductors By Induction
Generally, conductors like metals do not allow any excess charge to be present on them. Any excess charge added to metals easily flows away, for example, when a metal is placed on the Earth. This process is called earthing.
However, conductors can be charged by a process called induction. For example, consider charging a...
