PurposeTo evaluate with magnetic resonance elastography (MRE) whether patients with constrictive pericarditis (CP) have increased hepatic stiffness. CP results in reduced pericardial compliance, ventricular interdependence, and right heart failure. Patients with untreated CP may develop liver fibrosis and ultimately cirrhosis due to chronic venous congestion. Chronic venous congestion ± fibrosis may lead to increased liver stiffness.Materials and MethodsProspectively, patients with suspected CP underwent 2D transthoracic echocardiography, cardiac MRI, and liver MRE. An automated method was used to draw regions of interest (ROIs) on the stiffness maps to calculate the mean liver stiffness in kilopascals (kPa). A t‐test with α = 0.05 was performed between stiffness values of patients with positive and negative CP findings based on previously published echocardiography criteria.ResultsNineteen patients met inclusion criteria with a mean ± standard deviation (SD) age of 51 ± 16 years. Nine patients (47%) had CP. Mean liver stiffness trended higher in patients with CP compared to those without CP (4.04 kPa vs. 2.46; P = 0.045). Liver stiffness correlated with MRI septal bounce (P = 0.04), inferior vena cava size (P = 0.003), echo abnormal septal motion (P = 0.04), and echo mitral inflow variation >25% (P = 0.02). Only MRI septal bounce predicted CP by echocardiography (P < 0.001).ConclusionCP was associated with increased liver stiffness. The increased stiffness is most likely secondary to chronic hepatic venous congestion and/or fibrosis. MRE may be useful for noninvasive liver stiffness assessment in CP. J. Magn. Reson.

Abstract Background Cervical dystonia is thought to result in high disease burden, but limited information exists on its impact on employment and work productivity. We utilized data from the Cervical Dystonia Patient Registry for the Observation of OnabotulinumtoxinA Efficacy (ClinicalTrials.gov identifier: NCT 00836017) to assess the impact of cervical dystonia on employment and work productivity and examine the effect of onabotulinumtoxinA treatments on work productivity. Methods Subjects completed a questionnaire on employment status and work productivity at baseline and final visit. Baseline data were examined by severity of cervical dystonia, predominant subtype, presence of pain, prior exposure to botulinum toxin, and/or utility of a sensory trick. Work productivity results at baseline and final visit were compared in subjects who were toxin‐naïve at baseline and received three onabotulinumtoxinA treatments. Results Of 1,038 subjects, 42.8% were employed full‐ or part‐time, 6.1% unemployed, 32.7% retired, and 11.8% disabled. Of those currently employed, cervical dystonia affected work status of 26.0%, caused 29.8% to miss work in the past month (mean, 5.1 ± 6.4 days), and 57.8% reported decreased productivity. Half of those unemployed were employed when symptoms began, and 38.5% attributed lost employment to cervical dystonia. Pain, increasing severity, and anterocollis/retrocollis had the largest effects on work status/productivity. Preliminary analyses showed that absenteeism and presenteeism were significantly decreased following onabotulinumtoxinA treatments in the subpopulation that was toxin‐naïve at baseline. Conclusions This analysis confirms the substantial negative impact of cervical dystonia on employment, with cervical dystonia‐associated pain being a particularly important driver. OnabotulinumtoxinA treatment appears to improve work productivity.

Background and Purpose— The association between hemorrhagic stroke and use of nonsteroidal anti-inflammatory drugs (NSAIDs) is not well established. We conducted a systematic review and meta-analysis of observation studies to further characterize this possible association. Methods— Case–control and cohort studies that reported odds ratio, relative risk, hazard ratio, or standardized incidence ratio comparing risk of hemorrhagic stroke among NSAIDs users versus nonusers were systematically searched. Point estimates from each study were extracted. Pooled risk ratios (RR) and 95% confidence intervals (CI) for all NSAIDs and individual NSAIDs were calculated using random-effect, generic inverse variance method. Results— Ten studies were identified and included in our data analysis. As a single group, NSAIDs use was associated with a small but insignificant risk of hemorrhagic stroke with the pooled RR of 1.09 (95% CI, 0.98–1.22). Individual NSAIDs analysis revealed a significantly increased risk among diclofenac and meloxicam users (RR 1.27; 95% CI, 1.02–1.59 and RR 1.27; 95% CI, 1.08–1.50, respectively). The risk estimate for rofecoxib users was higher, but statistically nonsignificant (RR 1.35; 95% CI, 0.88–2.06). Conclusions— Overall, the use of NSAIDs is not associated with an increased risk of hemorrhagic stroke, although this risk was modestly significantly elevated in diclofenac and meloxicam users.

AbstractBackgroundFactors predicting locoregional relapse after surgery for oropharyngeal squamous cell carcinoma (SCC) were identified in the pre‐human papillomavirus (HPV) era. We examined whether traditional indications for adjuvant radiotherapy (RT) or adjuvant chemoradiotherapy (CRT) still correlate with locoregional relapse in HPV‐positive patients after transoral robotic surgery (TORS).MethodsRetrospective review of oropharyngeal SCC cases identified patients with HPV‐positive tumors who did not receive adjuvant therapy after TORS despite intermediate or high‐risk features.ResultsMedian follow‐up was 26.7 months (range, 4.9–73.1 months). Five of 25 eligible patients (20%) relapsed at a median 4.8 months (range, 3.2–7.8 months). Two of 18 (11%) intermediate and 3 of 7 (43%) high‐risk patients relapsed. Kaplan–Meier 2‐year locoregional relapse‐free survival estimates for intermediate and high‐risk patients were 88% and 57% (p = .078), respectively.ConclusionTraditional indications for adjuvant RT or CRT were associated with high risk of locoregional relapse in HPV‐positive patients treated with TORS alone. © 2015 Wiley Periodicals, Inc.
