Preventing aspiration incidents: redesigning inhalers for enhanced safety: A case study of coin aspiration

The conventional metered dose inhaler (MDI) has long served as a cornerstone in the management of asthma and chronic obstructive pulmonary disease (COPD), affecting millions annually. Despite its advantages, a persistent challenge is seen in the form of patient education and the unchanged design of these inhalers since their inception in 1956. This lack of progress in MDI design has inadvertently contributed to incidences of foreign body inhalation. In this case presentation we report a 50-year-old male with a past medical history of asthma, who faced an incident of foreign body inhalation with use of his inhaler. The patient aspirated a dime when he administered his inhaler, as it had become lodged in the device's mouthpiece, which was uncapped. This case, like many others, demonstrates the need for innovative changes in MDI inhaler design. While numerous articles or cases concentrate on foreign body removal, the primary objective of this case report is to investigate preventative measures and solutions aimed at averting incidents of inhalation.

Foley catheter technique for the extraction of coins lodged in the upper esophagus of children

INTRODUCTION

Coins are the most commonly ingested foreign bodies in children. They usually become lodged in the upper oesophagus and should be managed immediately. The aim of the present study was to evaluate the characteristics and outcomes of patients with coins lodged in the upper oesophagus, who underwent coin removal using a silicone Foley balloon catheter without fluoroscopy or anaesthesia and evaluate the safety of the procedure.

MATERIALS AND METHODS

Patients who were admitted from January 2007 to December 2022 for coins lodged in the oesophagus and extracted with silicone Foley balloon catheter without anestehesia were evaluated retrospectively. We focused on the patient characteristics and clinical presentations, and the treatment safety, efficacy, and outcomes.

RESULTS

773 patients (416 male, 357 female), with a mean age of 3.5 years (range 6 months to 16 years), who ingested coin and extracted with Foley catether is included. The majority of patients (n = 728, 94.17%) were successfully managed by silicone Foley balloon catheter extraction. Our overall success was 94.17%, with 88.30% of coins retrieved and 5.9% pushed into the stomach. Patients who were successfully treated with Foley catheter were discharged on the same day except for 7 (0.90%) who had minimal bleeding. Only 45 (5.82%) patients required oesophagoscopy in the operating room and these patients were kept overnight for clinical follow-up, without any further interventions.

CONCLUSION

A Foley balloon catheter can be used to safely and effectively remove coins that are lodged in the upper oesophagus avoiding the risk of general anesthesia.

Management of Gastrointestinal Foreign Bodies with Brief Review of the Guidelines

Foreign body (FB) ingestion is a common health problem that affects children more than adults. According to gastroenterologists' guidelines, the management of FB ingestion differs slightly between adult and children. This review aimed to compile adult and children guidelines and establish an understandable association to reveal the requirements and timing of the endoscopic procedure, which is the most effective and least complicated technique for gastrointestinal FBs. Coins, pins, and chicken and fish bones have been the most commonly ingested FBs. However, with their increasing use in recent years, large batteries with lithium-ion conversion, stronger magnets composed of rare earth metals, such as neodymium, and superabsorbent objects have become the most morbid and mortal, necessitating new management strategies. Although the approach to gastrointestinal FBs is controversial, with different treatment options available in different disciplines, many studies have demonstrated the efficacy and safety of endoscopic procedures. Many factors influence the timing of endoscopy, including the nature, size, and location of the ingested object and the patient's clinical condition.

Esophageal discoid foreign body detection and classification using artificial intelligence

BACKGROUND

Early and accurate radiographic diagnosis is required for the management of children with radio-opaque esophageal foreign bodies. Button batteries are some of the most dangerous esophageal foreign bodies and coins are among the most common. We hypothesized that artificial intelligence could be used to triage radiographs with esophageal button batteries and coins.

OBJECTIVE

Our primary objective was to train an object detector to detect esophageal foreign bodies, whether button battery or coin. Our secondary objective was to train an image classifier to classify the detected foreign body as either a button battery or a coin.

MATERIALS AND METHODS

We trained an object detector to detect button batteries and coins. The training data set for the object detector was 57 radiographs, consisting of 3 groups of 19 images each with either an esophageal button battery, esophageal coin or no foreign body. The foreign bodies were endoscopically confirmed, and the groups were age and gender matched. We then trained an image classifier to classify the detected foreign body as either a button battery or a coin. The training data set for the image classifier consisted of 19 radiographs of button batteries and 19 of coins, cropped from the object detector training data set. The object detector and image classifier were then tested on 103 radiographs with an esophageal foreign body, and 103 radiographs without a foreign body.

RESULTS

The object detector was 100% sensitive and specific for detecting an esophageal foreign body. The image classifier accurately classified all 6/6 (100%) button batteries in the testing data set and 93/95 (97.9%) of the coins. The remaining two coins were incorrectly classified as button batteries. In addition to these images with a single button battery or coin, there were two unique cases in the testing data set: a stacked button battery and coin, and two stacked coins, both of which were classified as coins.

CONCLUSION

Artificial intelligence models show promise in detecting and classifying esophageal discoid foreign bodies and could potentially be used to triage radiographs for radiologist interpretation.

Contamination of coins and banknotes as sources of transmission of parasitic pathogens: a pilot study from Iran

OBJECTIVE

This study was conducted to determine the presence, type, and rate of parasitic contamination in Iranian currencies.

STUDY DESIGN

This was a cross-sectional study.

METHODS

Coins and banknotes of different denominations were randomly collected from sellers and markets in Tabriz, Northwest of Iran, for examining parasitic contamination.

RESULTS

Entamoeba coli and Giardia intestinalis were the most identified species of parasites in this study. Other parasites detected were Cryptosporidium parvum, Ascaris lumbricoides, Entamoeba histolytica, Fasciola hepatica, and Toxocara cati. A high rate of parasitic contamination was found in banknotes compared with coins, and a statistically significant association was found between parasitic contamination and the apparent condition of the currencies. The notes of lower denominations showed the highest contamination rates. The highest parasitic contamination was found in coins and banknotes obtained from public toilet services, butchers, and beggars.

CONCLUSIONS

The findings emphasize the role of circulating coins and banknotes in the risk of pathogenic parasite transmission.

The requirements of cryptocurrency for money, an Islamic view

This research aims to evaluate the suitability of cryptocurrency as money from the Islamic perspective. Money, in the Islamic perspective, has specific characteristics and requirements, such as stability and is based on assets. Cryptocurrency may not fulfil this as it has queries as money from the Islamic perspective. The research method applied data of 23 cryptocurrency prices and related information. The result shows that cryptocurrency is hugely volatile and has limits to being called ‘money,’ as it is limited and used for speculation, which is prohibited in Islam. The research implies that Muslims would be reluctant to use cryptocurrency as money, as a currency of transaction. This reason raise an expectation that the cryptocurrency will not develop rapidly in Muslim countries.

Which coin is easier to pass esophagus spontaneously?

OBJECTIVE

To determine the factors associated with the spontaneous passage (SP) of coins lodged in the esophagus in children.

SUBJECTS AND METHODS

A total of 351 pediatric patients with coin ingestion admitted to our hospital from March 2016 to March 2019 were included in the study. The patients underwent a period of overnight watch with a repeated chest x-ray within 24 h after the commencement of hospitalization. The influencing factors (sex, age, types of coin, time in the esophagus, and location) were analyzed.

RESULTS

The repeated chest x-ray showed coins that had passed into the stomach or intestine in 68 patients. Sex, age, time in the esophagus, location in the esophagus or the types of coins were not associated with SP, but the distribution of the esophageal coins varied statistically significantly in the different ages.

CONCLUSION

Coins pass spontaneously through the esophagus (19.4%) within 24 h, unrelated to sex, age, time of esophagus lodging, coin location in the esophagus, or coin types. Children approximately two years old were more likely to ingest small coins (10 or 50 cents), whereas children approximately five years old were more likely to ingest a large coin (1 Yuan).

Predictive factors associated with spontaneous passage of coins: A ten-year analysis of paediatric coin ingestion in Australia

OBJECTIVES

Coins are the commonest foreign body ingested in paediatric populations. Although most ingested coins are either spontaneously passed or retrieved with medical intervention without serious consequence, there is potential for serious morbidity and mortality related to paediatric coin ingestion. We performed a 10-year retrospective review of Australian denomination coin ingestion at a tertiary paediatric hospital in Sydney, Australia. We attempted to determine whether a relationship exists between coin size, patient age, coin ingestion and spontaneous passage.

METHODS

Hospital records of all children presenting in a 10-year period to a paediatric tertiary care centre for coin ingestion were reviewed. Demographic information, coin denomination, previous history, symptoms, investigations, management, outcome and complications were recorded.

RESULTS

241 cases were identified. The majority (55%) of cases occurred in children ≤3 years of age (range 7 months-11 years, mean 3.39 years). The most common location where coins were identified was in the proximal third of the oesophagus or at the cricopharyngeus (65%). Spontaneous passage occurred in 84 cases (34.9%) while 167 cases (69.3%) required intervention. Children ≤3 years were more likely to ingest small coins (<22 mm) (OR: 2.44; 1.39-4.17) and children >3 years were more likely to ingest larger coins (22-26 mm) (OR: 2.17; 1.39-4.35).

CONCLUSIONS

Coin size, coin weight and age of the child appear to be predictors for both likelihood of ingestion and spontaneous passage in paediatric coin ingestion cases. A child with minimal symptoms, witnessed ingestion and radiographic identification of the coin in the lower oesophagus or more distal can often be safety observed for up to 24 h in anticipation of spontaneous passage.

Utilization of a handheld metal detector protocol to reduce radiation exposure in pediatric patients with esophageal coins

OBJECTIVE

The primary objective of this study is to assess the utility of a handheld metal detector for identification and surveillance of patients with known esophageal coin ingestion to reduce repeat x-rays and associated radiation exposure.

METHODS

Prospective study of children presented to the emergency department with esophageal coins confirmed by an initial x-ray were enrolled. The otolaryngology team used the handheld metal detector to detect and localize the coin on patient. If admitted for observation, the metal detector was used to ensure coin persistence prior to going to operating room for removal. No further x-rays were done if same location is confirmed.

RESULTS

A total of 19 patients (10 months-14 years) with 20 esophageal coins were enrolled. 14 patients (73.7%) were initially detected in the emergency department by the metal detector. 11 (58%) asymptomatic patients admitted for period of observation, repeat x-rays were avoided in 10 (90.9%) patients prior to removal in the OR. All proximal esophageal coins were detected with the metal detector. There were 5 (26.3%) patients who failed initial detection of coin, and all of these were in the mid-distal esophageal location with depth from skin >7 cm.

CONCLUSION

A handheld metal detector is rapid, cost-effective surveillance tool to reduce exposure to radiation from repeated x-rays in patients with esophageal coins. In contrast to all prior published studies, which did not objectively examine depth, the distance of the coin from skin surface appears to be a major limitation. Parents have provided positive feedback on the protocol.

The financial impact of flipping the coin

BACKGROUND

Esophageal foreign body retrieval is typically performed by rigid or flexible esophagoscopy. Despite evidence supporting the efficacy and safety of balloon extraction, it is rarely performed. We sought to establish the financial benefits of this minimally invasive approach.

METHODS

A retrospective review of 241 children with esophageal coins between 2011 and 2013 was performed. Coins were removed via endoscopy or fluoroscopic-guided balloon retrieval. Timing, symptoms, facility cost, and patient charges were compared.

RESULTS

Two hundred patients had attempted balloon retrieval with 80% success. Forty-one patients went directly for operative removal. Patients with respiratory difficulty (p=0.05), wheezing (p<0.01), or fever (p=0.03) were more often taken directly for endoscopic retrieval. The median cost and charges for attempted balloon extraction were $484 and $1647. The median cost and charges for primary endoscopy were $1834 and $6746. The median total cost and charges of attempted balloon extraction including ED, OR, transport, admission, and balloon retrieval were $1231 and $3539 versus $3615 and $12,204 in the primary endoscopy group (p<0.001, p<0.001). Seventeen percent of patients who underwent attempted balloon retrieval were admitted prior to removal compared to 76% who underwent primary endoscopy (p<0.001).

CONCLUSIONS

Fluoroscopic guided balloon extraction of esophageal coins is a financially prudent choice which shortens hospital stay.

The Vulnerable Indian One Rupee Coin

Coins are the most commonly ingested foreign body encountered in the pediatric population, with a peak incidence between 6 months and 3 years of age. Although some ingested coins may be aspirated, most coins pass through the alimentary tract without causing any complications. Coins in the esophagus causing symptoms require immediate removal. The management of asymptomatic coins has been a perplexing problem to the clinicians for decades. We recently managed an interesting case of an impacted Indian one rupee coin in the esophagus of a 13-year-old girl, by performing a simple yet novel technique, by using a conventional flexible endoscopic biopsy forceps. Further, reviewing the literature we inferred that the rounded, stainless steel Indian one rupee coin with a diameter of 25 mm, by itself seems to be vulnerable for impaction in the esophagus and therefore needs to be promptly addressed even if asymptomatic.

Updates in pediatric gastrointestinal foreign bodies

Although most ingested foreign bodies in children pass spontaneously, certain foreign bodies can be harmful and they require special attention and emergent medical intervention to prevent significant morbidity and mortality. This article presents an overview of the epidemiology, diagnosis, management, and complications of foreign body ingestions in children. Particular attention is paid to coins, sharp objects, long objects, food bolus, caustic liquids, batteries, and magnets.

Endoscopic retrieval of 28 foreign bodies in a 100-year-old female after attempted suicide

Foreign body ingestion is a common emergency situation in children with one or a few objects having been ingested. Here we report our experience using endoscopic retrieval in a female centenarian with dyspnea and foreign bodies in the esophagus. She attempted suicide by swallowing 26 coins and two other foreign bodies. A gastroscope was used to remove all foreign bodies in the lower esophagus. In total, 26 coins, one ferrous ring and one cylindrical plastic object were retrieved. To our knowledge, this is the first clinical report on retrieval of so many foreign bodies in a single case.

Foreign body in ear, nose and throat: experience in a tertiary hospital

To study the incidence of various foreign bodies in patients of different age and sex, attending E.N.T. Department, a retrospective review was done in Department of E.N.T., Burdwan Medical College and Hospital, Burdwan. About 334 patients with foreign body in ENT region presented to Department of E.N.T., Burdwan Medical College and Hospital from October 2008 to September 2010 were included in the study. Foreign body in ENT region is a common problem frequently encountered in both children and adults. Their accurate diagnosis and management without any complications is often challenging.
