Unusual Foreign Body Aspiration as a Cause of Asphyxia in Adults: An Autopsy Case Report

A 68-year-old man with haemoptysis and extensive ipsilateral lung infiltrates

A 68-year-old male presented to the emergency department with a 24-h history of haemoptysis and fever. The patient also reported a productive cough for 5 years. He was a current smoker (smoking history of 80 pack-years) with an otherwise unremarkable past medical history. On examination, his respiratory rate was 24 breaths per min, heart rate was 120 beats per min, temperature 39.2°C and his oxyhaemoglobin saturation was 98% in room air. On auscultation, breath sounds were reduced and end-expiratory crackles were heard over the left lung. Physical examination was otherwise normal. Blood tests showed: white blood cells 14 500 cells·μL⁻¹ (neutrophils 12 000 cells·μL⁻¹, lymphocytes 1900 cells·μL⁻¹), haemoglobin 13.9 g·dL⁻¹, platelets 256 000 μL⁻¹, C-reactive protein (CRP) 128 mg·L⁻¹, erythrocyte sedimentation rate 90 mm·h⁻¹, normal electrolytes, urea 45 mg·dL⁻¹ and creatinine 1.22 mg·dL⁻¹.

Can you diagnose this 68-year-old male with 24-h history of haemoptysis, 5-year history of productive cough and ipsilateral lung infiltrates?https://bit.ly/3tyhANB

Management of a case of unacknowledged foreign body in the upper airway

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.

Alive in the Airways: Live Endobronchial Foreign Bodies

Aspiration of a foreign body into the lower airways is a common occurrence and can cause significant morbidity and mortality in humans. Most foreign bodies of the tracheobronchial tree are inanimate. However, the medical literature includes reports of live foreign bodies in the airways. Fish, leeches, and roundworms are the most common live foreign bodies of the lower airways. Fishermen are more prone to experience a live fish aspiration, whereas substandard conditions may expose individuals to leech and roundworm infestations. The dangers of and the approaches to the management of these foreign bodies differ from those associated with aspirated inanimate objects. The focus of this review of the medical literature was on live foreign body aspiration and its management.

Successful flexible bronchoscopic management of a large-sized aspirated partial denture

A 48-year-old male patient presented to the emergency room with a history of chest pain and breathlessness. Chest X-ray demonstrated a large radio-opaque foreign body in relation to the proximal right bronchial tree. The patient subsequently revealed a history of a misplaced denture 4 months previously. Urgent flexible bronchoscopy (FB) examination demonstrated a large partial denture impacted in the right intermediate bronchus, which was removed successfully using a flexible bronchoscope. Although rigid bronchoscopy (RB) is the procedure of choice for large-sized and impacted airway foreign bodies, the present case highlights the utility of FB in airway foreign body removal. In clinically stable patients with foreign body inhalation, FB can be employed initially as it is an outpatient and cost-effective procedure which can obviate the need for administration of general anaesthesia.

Foreign body aspiration of a dental bridge in the left main stem bronchus

Aspiration of tracheobronchial foreign bodies is a life-threatening event that occurs mainly in children. Occurrence in adults is rare and usually has a subtle presentation as most adults are unaware of aspiration of any foreign material. Decreased levels of consciousness, sedation, and neuromuscular diseases are major risk factors for foreign body aspiration in adults. Prompt diagnosis and intervention through foreign body retrieval are critical to prevent significant morbidity and mortality. Retrieval procedure is risky, and sudden decompensation of the patient can occur anytime. We are presenting an adult who accidentally aspirated his dental prosthesis during sleep and underwent successful retrieval of the dental bridge using flexible bronchoscopy.
