Perturbed Ion Temperature and Toroidal Flow Profile Measurements in Rotating Neoclassical Tearing Mode Magnetic Islands.

The perturbed ion temperature and toroidal flow were measured in rotating neoclassical tearing modes (NTM) in a tokamak for the first time. These toroidally and radially resolved profiles were obtained by impurity ion spectroscopy in a 2,1 NTM in DIII-D. In agreement with drift-kinetic simulations, the electron temperature profile is flat, while the ion temperature gradient is restored across the magnetic island O point in the presence of fast ions; the perturbed flow has minima in the O points and maxima at the X points.

Clinically important estimates of improvement after septoplasty.

Objective: A statistically significant improvement in nasal obstruction ratings following septoplasty is not necessarily clinically important. This study aimed to establish useful measures of septoplasty success, namely the minimal clinically important difference and the desirable clinically important difference.

Methods: Patients rated nasal obstruction on a 0-100 visual analogue scale pre-operatively and at 5.

Septoplasty: early (first year) and late (fourth year) post-operative results in 604 patients.

Objective: As prospective outcomes of septoplasty with or without turbinoplasty beyond the first year are few and have diverging results, this study evaluated later septoplasty results three to four years post-operatively.

Methods: Patients undergoing septoplasty completed the Nasal Surgical Questionnaire pre-operatively, and at 6-12 months (early post-operative assessment) and 36-48 months (late post-operative assessment) after surgery. Primary outcome was visual analogue scale ratings for nasal obstruction (with a scale ranging from 0 to 100).

Self-Reported Complications after Tonsillectomy: Comparison of Responders and Nonresponders to a Mailed Questionnaire.

Some studies of tonsillectomy outcomes have low response rates to mailed quality control questionnaires. This study evaluated the effect of nonresponders to mailed questionnaires about posttonsillectomy complications by determining whether mail responders and nonresponders differ. Questionnaires were mailed to patients 3-6 weeks after tonsillectomy to assess postoperative complications, defined as contact with a private practitioner and/or hospital readmission related to postsurgical bleeding, pain, or infection.
