Foreign body aspirations are commonly seen in emergency departments (EDs) worldwide, presenting with cough, dyspnea, wheeze, and decreased air entry. Chest radiographs are commonly utilized diagnostic tools to confirm foreign object aspiration. The following is a case report of a child who presented in the ED with a carinal push-pin aspiration and a lack of respiratory symptoms; an extremely rare ED presentation of foreign body aspirations masquerading as a foreign body ingestion.

Grass awns commonly cause respiratory disease in dogs; when located in the trachea or bronchi, they cause severe bronchial inflammation and sepsis. The interplay of cough, bronchoconstriction, and mucus secretion can result in a less effective expulsive cough phase, especially when the causal factor persists. The bronchial exudate could consequently become trapped in the upper respiratory tracts of dogs with bronchial vegetal foreign bodies. Read More

Recognizing and acting early on airway compromise reduces morbidity and mortality in patients with airway obstruction. Causes include foreign bodies, toxic/hot fumes, difficult intubation, laryngeal spasm, and tumors. Before definitive control of the airway is possible, provide 100% oxygen with a tightly fitting mask to optimize body oxygen stores. Read More

Tracheobronchial foreign body aspiration occurs rarely in adults and may go unrecognized for a long time, but early detection and immediate retrieval of the foreign body are essential to prevent major morbidity. We describe the case of an adult who unusually aspirated part of his dental prosthesis during an attempted strangulation, which was unacknowledged until 6 months later when he was hospitalized with acute respiratory failure and required an emergency surgical tracheotomy. The foreign body was successfully removed via flexible bronchoscopy. Read More

Aspiration of foreign-bodies remains a major life-threatening situation in children and have always been a source of interest and confusion to otolaryngologists due to their varied presentations. These conditions if not promptly diagnosed and managed can prove to be fatal, but the current mortality is only one percent compared to pre bronchoscopy era (Rothman and Boeckman in Ann Otol Rhinol Laryngol 89:434-436, 1980). Peak incidence of this condition is in early childhood due to child's habit of putting small objects in mouth to determine their taste and texture and chew while teething. Read More

Background: Coins are made of metal, which is generally radiopaque, and so physicians often have the misconception that all coins are detectable by radiography. Here, we report a case of intentionally swallowed coins in the oesophagus of an adult; the coins could not be detected on chest radiography but were detected using computed tomography (CT).

Case Presentation: A 46-year-old woman with a history of depression presented to the emergency department after an intentional medication overdose and ingestion of two Japanese 1-yen coins. Read More
