Dexmedetomidine sedation for awake fiberoptic intubation of patients with difficult airways due to severe odontogenic cervicofacial infections.

Purpose: Odontogenic infections present challenging airway scenarios to surgeons and anesthesiologists. Among specialists, there is controversy over airway management for those patients with airways made difficult by trismus and swelling with anatomic impingement and derangement. Awake fiberoptic intubation has achieved favor in the oral and maxillofacial surgery and anesthesiology communities for management of such difficult airways, but patient comfort and anxiety management with traditional agents may prove hazardous because of potential suppression of protective mechanisms and respiratory depression.

Clear cell atypical fibroxanthoma:a clinicopathologic study.

Introduction: The atypical fibroxanthoma (AFX) is considered by most authorities to represent a superficial or minimally invasive variant of malignant fibrous histiocytoma that most often presents as a solitary nodule on the sun-exposed skin of the elderly. Among the rarest variants is the clear cell AFX, a lesion which raises consideration to a differential diagnosis encompassing a variety of neoplastic and non-neoplastic clear cell proliferations.

Methods: We describe three cases of a distinctive cutaneous neoplasm arising in the sun-exposed skin of elderly patients.
