Gastric Volume and Its Relationship to Underlying Pathology or Acid-suppressing Medication.

Background: Pulmonary aspiration during sedation is a major concern for sedation providers, making identifying high-risk patients a priority. Gastric fluid volume (GFV), an accepted risk factor for aspiration, has not been well characterized in fasting children. We hypothesized that GFV would increase with gastrointestinal (GI) pathology and decrease with regular acid-suppressor use.

Comparative assessment of change in fat mass using dual X-ray absorptiometry and air-displacement plethysmography.

Objective: To compare the accuracy of body composition measurements to small, defined changes in fat mass between dual X-ray absorptiometry (DXA) and air-displacement plethysmography (ADP).

Methods: Fifty-six healthy adults, 29 women and 27 men (age, 38 ± 12.4 years; BMI, 27.

Retinal and choroidal arterial occlusion in Wegener's granulomatosis.

Purpose: To describe a patient with Wegener's granulomatosis presenting with bilateral retinal and choroidal arterial occlusion.

Methods: A 64-year-old male with Wegener's granulomatosis was examined using ophthalmoscopy and indocyanine green angiography.

Results: The patient had central retinal arterial occlusion in the right eye and branch retinal arterial occlusion in the left eye associated with bilateral choroidal infarcts.
