Show moreObjectives A last resort for therapy for intractable benign paroxysmal positional vertigo (BPPV) is mechanical occlusion of the posterior semicircular canal. The aim of this review was to assess the effect of posterior canal occlusion for intractable posterior canal BPPV on vertigo and to determine the risk of loss of auditory or vestibular function. Data Sources A systematic literature search according to the PRISMA statement was performed on PubMed, the Cochrane Library, Embase, Web of Science, and CINAHL. The last search was conducted in June 2018. Review Methods Cohort studies with original data and case reports describing >5 cases were included if they analyzed the effect of posterior semicircular canal obliteration in adults with intractable posterior BPPV on vertigo. Two authors screened titles and abstracts for eligibility. The first author screened full texts and analyzed the data. Results Eight retrospective studies met the eligibility criteria. The quality of all individual studies was rated fair. Canal occlusion was performed on 196 patients. All studies reported complete resolution of BPPV in all patients (100%). Among postoperatively tested patients, total loss of auditory function and vestibular function was reported in 2 of 190 (1%) and 9 of 68 (13%), respectively. Conclusion Posterior semicircular canal plugging resulted in 100% resolution of BPPV in patients with intractable BPPV in all studies. However, the strength of evidence was weak. Potential serious complications, such as deafness and loss of vestibular function, should be taken into account. Show less

Show moreObjective: To analyze and compare experiences of anxiety and discomfort caused by the Epley maneuver and the willingness for a potential retreatment between younger (≤70 yr) and older (>70 yr) patients.Study design: Prospective, observational cohort study.Setting: Tertiary referral center.Methods: Dutch adults, diagnosed with posterior canal benign paroxysmal positional vertigo, were included. Patients with dementia or subjected to an Epley maneuver ≤4 months before the hospital visit were excluded. Patients were asked about their experiences with the Epley maneuver directly after the maneuver, after 2 weeks and after 2 months. Differences in experiences between the age groups were tested with the Fisher's exact test and subgroup analyses were performed using multivariable logistic regression.Results: Out of 179 included patients, 115 (64%) were aged ≤70 and 134 (75%) were female. In both groups, 25% reported anxiety directly after the Epley maneuver. Two weeks later, 19 and 27%, respectively (p = 0.26) reported anxiety. In the young group, 30% expressed discomfort directly after treatment compared with 45% in the elderly (OR 1.98, 95% CI 1.05-3.75, p = 0.04). Two weeks later, this was 36 and 38%, respectively (p = 0.87). This decreased to 24 and 33%, respectively (p = 0.37), after 2 months. There was no significant difference in willingness for potential retreatment between both groups after 2 weeks (93 and 95%, respectively, p = 0.75) nor after 2 months (97 and 92%, respectively, p = 0.13).Conclusion: The Epley maneuver results in little anxiety and discomfort both in young and in elderly patients. Most patients show willingness for potential retreatment in case symptoms recur. Show less

Show moreObjectives: To evaluate non echo-planar diffusion weighted magnetic resonance imaging (non-EP DW MRI) at 9 months after primary surgery to rule out residual cholesteatoma in patients scheduled before second-look-surgical exploration.Study Design: Prospective observational study.Setting: Secondary teaching hospital.Patients/Interventions: Patients who were scheduled for second-look-surgery after primary canal wall up repair of cholesteatoma underwent 1.5 T MRI including non-EP DWI and high-resolution coronal T1 and T2-FS SE sequences.Main Outcome Measures: Imaging studies were evaluated for the presence of cholesteatoma by three independent observers. Intraoperative observations were regarded the standard of reference. Ear, nose, throat (ENT) surgeons were blinded for imaging findings. The primary outcome was the negative predictive value (NPV) of MR imaging, secondary outcomes were sensitivity, specificity, and positive predictive value.Results: Thirty-three patients underwent both MRI and surgery, among whom 22 had a cholesteatoma. Mean time between primary surgery and MRI was 259 days (standard deviation [SD] 108). NPV of non-EP DW MRI in detecting recurrent cholesteatoma was 53% (95% CI: 32-73%). Sensitivity and specificity were 59% (39-77%) and 91% (62-98%), respectively. The positive predictive value was 93% (69-99%). In five out of nine false-negative cases, recurrent cholesteatoma measured 3mm or less. Using a 3mm detection threshold, NPV increased to 79%.Conclusion: Non-EP DW MRI cannot replace second look surgery in ruling-out residual cholesteatoma at 9 months after primary surgery. It could be used in a follow-up strategy in low risk patients. Further research is needed which types of residual cholesteatoma are not revealed by MRI. Show less

Show moreBACKGROUND The number of studies on the prognostic value of the right ventricular ejection fraction (RVEF) in patients with ischemic heart disease (IHD) is limited, whereas it is widely accepted that the left ventricular ejection fraction (LVEF) is a strong prognostic factor. We assessed whether RVEF measured by multigated planar equilibrium radionuclide ventriculography (RNV) is an independent prognostic factor in patients with IHD. METHODS AND RESULTS We retrospectively identified 347 consecutive patients with IHD (mean age 71 ± 11 years; 18% women) who underwent multigated planar equilibrium RNV between 2004 and 2008 to determine the LVEF, which also provided the RVEF (mean 44.7% ± 11.0%). We categorized patients according to RVEF in ≥40% (n = 240) and <40% (n = 107). Patients were followed for a median of 826 days (range 3-2,400) for the occurrence of events [all-cause mortality (n = 60), cardiac mortality (n = 33), and cardiac hospitalization (n = 78)]. Cox regression analysis with significant univariate predictors [coronary artery revascularization (P = .003), diuretics (P = .03), and statins (P < .001)] showed that an RVEF <40% was associated with a 2.90 (1.68-5.00)-fold higher risk of all-cause death. Accordingly, a decreased RVEF was associated with a 2.15 (1.34-3.43)-fold increase in the risk of cardiac hospitalization and a 5.11(2.32-11.23)-fold risk of cardiac death. CONCLUSION RVEF measured by multigated planar equilibrium RNV is an independent prognostic factor in patients with chronic IHD. Show less
