A case of fibrosis in the cheek of a 42-year-old woman is presented. The panoramic radiograph showed a well-defined, round radiopacity in the maxillary right third molar region. Other techniques revealed that it was a superimposition. The lesion was hard and painless and associated with hypertrophic scarring secondary to a burn injury many years earlier. Clinicians must be aware of the radiologic image of this fibrosis, so as not to confuse it with other radiopaque lesions of hard tissue origin that occur in both arches. A differential diagnosis is described.

Closed-loop ventilation and oxygenation with decision support fluid resuscitation to treat major burn injury with smoke induced acute respiratory distress syndrome.
Shock
January 2025
Department of Anesthesiology, The University of Texas Medical Branch, Galveston, Texas.
Introduction: The understanding of the interaction of closed-loop control of ventilation and oxygenation, specifically fraction of inspired oxygen (FiO2) and positive end-expiratory pressure (PEEP), and fluid resuscitation after burn injury and acute lung injury from smoke inhalation is limited. We compared the effectiveness of FiO2, PEEP, and ventilation adjusted automatically using adaptive support ventilation (ASV) and decision support fluid resuscitation based on urine output in a clinically relevant conscious ovine model of lung injury secondary to combined smoke inhalation and major burn injury.
Methods: Sheep were subjected to burn and smoke inhalation injury under deep anesthesia and analgesia.
Cutaneous absorption of methylene chloride is rarely toxic. This case shows that it can lead to carboxyhemoglobinemia. Exposure to methylene chloride should warrant a carboxyhemoglobin check and oxygen support.

JAMA Netw Open
January 2025
Department of Surgery, University of Washington, Seattle.
Importance: Timely access to care is a key metric for health care systems and is particularly important in conditions that acutely worsen with delays in care, including surgical emergencies. However, the association between travel time to emergency care and risk for complex presentation is poorly understood.
Objective: To evaluate the impact of travel time on disease complexity at presentation among people with emergency general surgery conditions and to evaluate whether travel time was associated with clinical outcomes and measures of increased health resource utilization.
