Upper Airway Burn Injury
Overview: Inhalational injury is a broad term describing respiratory tract damage from heat, smoke, or chemical irritants. Upper airway injury is primarily thermal (heat absorbed in the naso-/oropharynx). Findings include mucosal erythema/ulceration/edema, airway compromise from swelling, and possible facial/neck burns. Impaired mucociliary clearance increases infection risk and distal airway obstruction.

Epidemiology:
- United States (2020): ~1.4 million fires, ~3,500 civilian deaths, ~15,200 injuries
- Up to 77% of deaths due to pulmonary complications (e.g., CO poisoning)
- Common Causes:
- Hot food/beverages
- Hot metal objects
- Dental procedures or airway lasers (iatrogenic)
- E-cigarette explosions
- Reverse smoking
- High-Risk Populations: Neurological impairment, denture wearers, extremes of age (children, elderly)
Clinical Presentation:
- Suspect based on exposure to heat, smoke, or chemicals
- Ask about duration of exposure, enclosed space, loss of consciousness
- Signs and Symptoms: Nausea/vomiting (consider CO poisoning), facial burns, singed nasal hairs, soot in nose/oropharynx, oral pain or drooling, hoarseness, stridor, lip/tongue/uvula swelling, tachypnea, sub-/suprasternal retractions
- Primarily clinical suspicion
- Flexible Nasopharyngoscopy: Assess edema and airway patency
- Labs: CBC, electrolytes, BUN/Cr, lactate, toxicology screen, ABG with co-oximetry (if CO exposure suspected)
- Chest Radiograph: Low sensitivity early
Management:
- Initial Priorities:
- ABCs with early airway protection
- Early Intubation Indications: for progressive hoarseness, stridor, decreased LOC, significant edema or blistering
- Supportive Care: Head elevation, fluid management, humidified oxygen
- Corticosteroids and antibiotics remain controversial

Question of the Week
A 58-year-old man presents with a left-sided neck mass that has progressively enlarged over the past 3 months. He denies odynophagia, dysphonia, and unintentional weight loss. He has a 30-pack-year smoking history and drinks alcohol socially. Physical examination reveals a firm 3.5-cm left level III cervical lymph node fixed to the underlying structures. Flexible laryngoscopy reveals subtle pooling of secretions in the left pyriform sinus but no obvious mucosal lesion. CT scan of the neck with contrast demonstrates a necrotic cervical lymph node with extranodal extension as well as asymmetric thickening of the hypopharyngeal mucosa. Panendoscopy with directed biopsies is negative for malignancy.
Which of the following is the most appropriate next step in management?
(A) Observation with repeat imaging in 3 months
(B) Repeat panendoscopy with random biopsies
(C) PET-CT scan of the head and neck to identify an occult primary tumor
(D) Open excisional biopsy of the necrotic cervical lymph node identified on CT
(E) Empiric chemoradiation to the neck without further workup

Deep Learning Model for Pediatric Middle Ear Disease

Can your smartphone diagnose an ear infection?
Otitis media is one of the most common pediatric diagnoses, yet distinguishing acute otitis media (AOM) from otitis media with effusion (OME) remains challenging and contributes to inappropriate antibiotic use. In this multicenter prospective cohort study, 737 tympanic membrane (TM) images from 219 children aged 6 months to 10 years undergoing myringotomy and tympanostomy tube placement were obtained using consumer-grade smartphone otoscopes to train a deep learning classifier. Images were labeled intraoperatively as AOM (N = 73, 9.9%), OME (N = 190, 25.8%), no effusion (N = 274, 37.2%), or no TM in image (N = 200, 27.1%). The model achieved a mean weighted accuracy of 92.5%, with category-specific weighted accuracies of 94.7% for AOM, 88.4% for OME, 87.9% for no effusion, and 98.8% for no TM in image. Precision ranged from 56.0% to 98.0%, and recall ranged from 77.0% to 98.0% across categories. Although the model was developed using anesthetized children in the operative setting, its strong performance suggests meaningful potential for translation into outpatient and telemedicine settings. This study represents an important step toward scalable, artificial intelligence (AI)-assisted otoscopic evaluation that may improve diagnostic accuracy, reduce inappropriate antibiotic prescribing, and expand access to pediatric ear care.
Emily Chestnut’s Takeaway: This study highlights how AI can be designed to prioritize both accuracy and equity. As telemedicine continues to expand, tools like this model may help bridge diagnostic gaps while supporting more responsible antibiotic use in pediatric populations.
