Primary Skull Base Lymphoma: Manifestations and Clinical Outcomes of a Great Imitator.
Objectives Primary skull base lymphoma (PSBL) represents a rare manifestation of extranodal lymphoma. Presenting with nonspecific symptomatology and imaging findings, PSBL often masquerades as more common cranial base pathology and thus can present a diagnostic challenge. The objectives of this study were to characterize the manifestations and clinical outcomes of PSBL. ⋯ Lymphoma within CSF portended significantly worse overall survival (85% vs 18% at 3-years; P < .001). Conclusion A history significant for multiple cranial nerve palsies, B-symptoms, and imaging findings inconsistent with common skull base pathology should raise suspicion for PSBL. CSF analysis in the setting of PSBL can provide diagnostic and prognostic value for patients.

Randomized Controlled Trial Multicenter Study Comparative StudyLidocaine/Phenylephrine Nasal Spray versus Nebulization Prior to Nasoendoscopy: A Randomized Controlled Trial.
Objective To objectively compare the nasal decongestion potency of lidocaine/phenylephrine when delivered with a nasal nebulizer and a nasal spray before a rigid nasoendoscopic examination. Study Design Open-label randomized controlled trial. Setting Multicenter study. ⋯ The examining endoscopist further supported the degree of nasal decongestion via subjective assessment of the nasal cavity ( P = .001). Pain scores obtained after the intervention showed a significant decrease in pain threshold when the nasal nebulizer was used instead of the nasal spray ( P = .040). Conclusions This study suggests that the delivery of lidocaine/phenylephrine to the nasal cavity by the nasal nebulizer provides better decongestive and analgesic potency as compared with the delivery by nasal sprays.

Objective To determine the incidence of posttracheostomy tracheal stenosis and to investigate variables related to the patient, hospitalization, or operation that may affect stenosis rates. Study Design A combined retrospective cohort and case-control study. Setting Tertiary care academic medical center. ⋯ Conclusion Greater than 10 days of orotracheal intubation prior to tracheostomy and endotracheal tube cuff pressure ≥30 mm H2O were associated with greater rates of subsequent tracheal stenosis. The only patient-related factor associated with tracheal stenosis was obesity. Surgical variables associated with increased rates of subsequent stenosis included placement of a tracheostomy tube size >6, use of percutaneous technique, and failure to create a Bjork flap.
