Background Computed tomography (CT) of the paranasal sinuses is the diagnostic reference standard for chronic rhinosinusitis and related inflammatory sinus pathology. Nasal nitric oxide (nNO) levels have been investigated as a diagnostic tool in sinus disease because it decreases with sinus obstruction. Objective The primary aim of the study was to determine the correlation of passive (baseline) and dynamic (humming) nNO to CT findings of sinus inflammation and to sinonasal symptoms measured by the modified Sinonasal Outcome Test (26 items) (SNOT-26). Methods From June 2015 through January 2016, subjects had baseline and humming nNO levels measured with a chemiluminescence NO analyzer, and each subject underwent CT imaging and completed the SNOT-26 survey. CT images were scored using the Lund–Mackay (LM) system (LM scores >3 indicated sinus inflammation). Correlation was measured by linear and ordinal regression analysis that compared SNOT-26 scores, LM scores, and nNO measurements. Results Fourteen subjects were recruited. LM scores had a positive pairwise correlation with total SNOT-26 scores ( R 2 = .1457; correlation = .3817) and nasal-specific SNOT-26 scores ( R 2 = .4036; correlation = .6353). Baseline nasal nNO scores had a negative pairwise correlation with LM scores ( R 2 = .1580; correlation = −.3582), total SNOT-26 scores ( R 2 = .1515; correlation = −.3893), and nasal-specific SNOT-26 scores ( R 2 = .0805; correlation = −.4343). Although baseline nNO levels correlated with LM and SNOT-26 scores, humming nNO levels did not show a similar correlation. Conclusion Baseline passive nNO may be a useful and inexpensive point-of-care screening test for sinonasal opacification.

AbstractAlthough periorbital edema and ecchymosis are commonly encountered after facial plastic and reconstructive surgery procedures, there is currently no validated grading scale to qualify these findings. In this study, the modified “Surgeon Periorbital Rating of Edema and Ecchymosis (SPREE)” questionnaire is used as a grading scale for patients undergoing facial plastic surgery procedures. This article aims to validate a uniform grading scale for periorbital edema and ecchymosis using the modified SPREE questionnaire in the postoperative period. This is a prospective study including 82 patients at two different routine postoperative visits (second and seventh postoperative days), wherein the staff and resident physicians, physician assistants (PAs), patients, and any accompanying adults were asked to use the modified SPREE questionnaire to score edema and ecchymosis of each eye of the patient who had undergone a plastic surgery procedure. Interrater and intrarater agreements were then examined. Cohen's kappa coefficient was calculated to measure intrarater and interrater agreement between health care professionals (staff physicians and resident physicians); staff physicians and PAs; and staff physicians, patients, and accompanying adults. Good to excellent agreement was identified between staff physicians and resident physicians as well as between staff physicians and PAs. There was, however, poor agreement between staff physicians, patients, and accompanying adults. In addition, excellent agreement was found for intraobserver reliability during same-day visits. The modified SPREE questionnaire is a validated grading system for use by health care professionals to reliably rate periorbital edema and ecchymosis in the postoperative period. Validation of the modified SPREE questionnaire may improve ubiquity in medical literature reporting and related outcomes reporting in future.

Study Design. Systematic review and meta-analysis. Objective. To compare postoperative surgical, radiographic, and patient-reported outcomes following anterior cervical discectomy and fusion (ACDF) with and without plate fixation. Summary of Background Data. ACDF has evolved significantly over the years, including the placement of an anterior plate construct. Although promoting bony osseo-integration at the fusion site, there are a number of plate-related complications that can arise. The non-plating approach is less invasive, however, greater rates of cage subsidence have been associated with this model. Methods. We performed an electronic literature search for human studies that directly compared ACDF with and without anterior plate fixation. Outcomes of interest comprised of postoperative dysphagia, fusion success, and cage subsidence as well as patient reported outcomes, including the Neck Disability Index (NDI) scores and Visual Analog Scale (VAS) for both neck and arm pain. Results. A total of 15 studies (12 observational and 3 randomized controlled trials) and 893 patients (57% males) were included. Overall, ACDF with plate fixation was associated with significantly higher vertebral fusion rates (odds ratio [OR] 1.98; 95% confidence interval [CI] 1.16–3.37), lower subsidence rates (odds ratio [OR] 0.31, 95% CI 0.18–0.52), and more favorable VAS-neck pain scores at last follow-up (mean difference [MD] 0.59, 95% CI −0.78 to −0.41). Conversely, ACDF procedures without plate fixation had marginally better long-term VAS-arm pain scores (mean difference [MD] 0.2, 95% CI 0.04–0.36). No difference was found with regards to dysphagia (OR 1.21, 95% CI, 0.57–2.56) and NDI (MD 0.06, 95% C.I −0.54 to 0.42). Conclusion. Available evidence, although limited, suggests superior surgical outcomes in ACDF procedures with anterior plate fixation (increased fusion, decreased subsidence) and slightly better VAS-neck pain scores at last follow-up. Future longitudinal, multicenter randomized controlled trials should be completed to validate any associations found in this study. Level of Evidence: 3
