Upper airway involvement in Stevens-Johnson syndrome and toxic epidermal necrolysis.

Background: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare life-threatening hypersensitivity conditions associated with epidermal detachment and mucositis. The indication for flexible nasoendoscopy (FNE) and overall predictive factors for early intubation are unclear.

Objectives: To describe the incidence of airway involvement and the key indicators for intubation in our SJS or TEN patient cohort.

Mitral Annular Plane Systolic Excursion as a predictor of Left Ventricular Ejection Fraction in mechanically ventilated patients.

Introduction: The accurate measurement of Left Ventricular Ejection Fraction (LVEF) requires high-quality images and echocardiography expertise. Critically ill patients can present challenges in obtaining good acoustic windows for ultrasound, particularly for ICU trainees early in their ultrasound learning. Mitral Annular Plane Systolic Excursion (MAPSE), a simple measurement, may be useful in this context to estimate LV systolic function.
