Measuring the Angular Accuracy of a Clinician-Performed Epley Maneuver Used to Treat Benign Paroxysmal Positional Vertigo.

INTRODUCTION: Particle repositioning maneuvers have become the criterion standard for managing benign paroxysmal positional vertigo. The Epley canalolith repositioning maneuver is used to treat posterior canal benign paroxysmal positional vertigo and is successful in up to 90% of cases. However, when performed, there are many clinician variabilities, and angles are approximate. It is not known how accurate each angle needs to be for the target canal to be adequately stimulated. The objective of this study was to measure the angular accuracy of clinician-guided Epley maneuvers using a three-axis accelerometer. METHODS: Ten healthy subjects were recruited; participants had no known audio vestibular pathology. Five right-hand-dominant clinicians performed Epley maneuvers on both ears of two different participants. Twenty maneuvers were carried out in total. Angular movements were recorded using a vestibular feedback electronic device, the SHIMMER accelerometer. Data were recorded and analyzed using the EYESWEB Open Platform. RESULTS: Results showed that there was angular error at every stage of the clinician-performed Epley maneuver. The most accurate movement was positioning the head to the left of 45 degrees for a left ear maneuver with an average error of 2.94 degrees. The least accurate was when positioning the patient to face the floor at 135 degrees from supine for a right ear maneuver with an average error of 17.6 degrees. CONCLUSION: Even when experienced ENT clinicians perform a standard Epley maneuver, there is a wide range of angular inaccuracy at each stage. Face to floor is particularly inaccurate. However, given that a majority of procedures (90%) work on the first attempt, there must be an acceptable but unknown range of angular inaccuracy. Novel technologies could improve the angular accuracy, potentially give better results, and allow a broad range of individuals to perform a more accurate Epley maneuver.

The impact of COVID-19 on acute urinary stone presentations: a single-centre experience.

BACKGROUND: The COVID-19 pandemic has seen a change in the numbers of patients presenting to the emergency department (ED) with non-COVID symptoms, resulting in delayed presentations of many medical and surgical conditions. AIMS: To examine the impact of COVID-19 on acute urolithiasis presentations to the ED. METHODS: In this retrospective, single-centre, observational study, we reviewed all CT KUBs (and their corresponding cases) ordered in ED for possible acute urolithiasis in a 100-day period immediately prior to COVID-19 and in a 100-day period immediately afterwards. We sought to establish the number of CT KUBs performed and the number confirming urolithiasis. We recorded patients' age, gender, stone size and location. We also analysed CRP, WCC and creatinine as well as the duration of patients' pain and the management strategy adopted for each case. RESULTS: One hundred ninety-eight CT KUBs were performed, 94 pre-COVID and 104 intra-COVID. A total of 70.2% (n = 66) and 66.3% (n = 69) were positive for urolithiasis pre-COVID and intra-COVID respectively (p = 0.56). There was a significantly higher percentage of females pre-COVID compared with intra-COVID (54% vs 36%, p = 0.012). There was no difference in median ureteric stone size seen between the groups (4.7 mm pre-COVID vs 4.0 mm intra-COVID, p = 0.179). There were no significant differences in WCC, CRP or creatinine levels. One patient in the pre-COVID group and two in the intra-COVID groups required percutaneous nephrostomies. CONCLUSION: The COVID-19 pandemic did not result in fewer or sicker patients presenting with acute ureteric colic cases to the ED.

A review of primary care referrals for patients with dizziness and vertigo: prevalence and demographics.

BACKGROUND: International studies show that dizziness and vertigo are a significant burden on the general population, with 20-30% experiencing symptoms over a lifetime. There are no Irish studies indicating prevalence. The aim of this study was to review primary care referrals for patients with dizziness and vertigo to an otolaryngology tertiary centre. METHODS: A review of an out-patient department waiting list was performed on primary care referrals for dizziness and vertigo to an otolaryngology tertiary centre. Demographic information was recorded on all patients referred between May 2017 and August 2019. RESULTS: Two hundred fifteen patients out of 901 patients (24%) referred to an otologist between May 2017 and August 2019 were referred with dizziness as a presenting complaint. The average age was 51 years. F/M ratio was 3:2. The average waiting time was 441 days. The most common associated otological symptom was tinnitus (42%). Relevant comorbidities included anxiety, depression, migraine/headaches and cardiac disease. CONCLUSION: This study demonstrates that a significant number of patients referred to an otologist from primary care are referred with dizziness and vertigo and supports the need for the establishment of multi-disciplinary vestibular/balance centres to address and manage these patients.

A comparison of oncological outcomes after abdominoperineal excision before and after the implementation of a selective perineal flap closure program.

BACKGROUND AND OBJECTIVES: Abdominoperineal excision (APE) is the operation chosen when a patient has low rectal cancer unamenable to sphincter preserving surgery. Perineal flap reconstruction is associated with less wound morbidity but little is known about oncological outcomes. The objective was to compare outcomes in patients undergoing APE before and after the introduction of a program that utilized flap reconstruction of the perineum. METHODS: A retrospective review of a prospectively maintained database was performed. Patients who underwent APE followed by primary closure or flap reconstruction between 1998 and 2018 were selected. The cohorts were divided according to the implementation of the flap reconstruction program in July 2009. Clinicopathological data, recurrence and survival were compared between the cohorts. RESULTS: One hundred and forty nine patients underwent APE for rectal adenocarcinoma between 1998 and 2018. There were 57 patients in the pre-flap era and 92 in the post-flap era. Forty-six patients underwent flap reconstruction in the latter cohort (50%). More patients in the post-flap era underwent neoadjuvant chemoradiotherapy (85.9% vs. 63.2%; p < .01). Margin positivity rates decreased from 21.1% in the pre-flap era to 10.9% in the post-flap era (p = .10) and there was an associated improvement in incidence and time to local recurrence (p = .03). CONCLUSION: The use of perineal flap reconstruction is associated with a longer median time to local recurrence. Perineal flap reconstruction may contribute to reduced margin positivity.

Implementation of day of surgery admission for rectal cancer surgery in Ireland following a national centralisation programme.

BACKGROUND: Centralisation of rectal cancer surgery has altered the delivery of colorectal cancer care in Ireland. This has resulted in an increased demand for elective surgical beds in designated centres. AIM: This study aimed to assess if day of surgery admission (DOSA), in conjunction with implementation of a coordinated enhanced recovery pathway can reduce length of stay following elective rectal cancer resection. METHODS: This is a retrospective review from a single institution. Our prospectively maintained Dendrite® Database was interrogated. Three time points were analysed across a 7-year period (2011, 2012, 2016). The first predates the introduction of a dedicated DOSA programme, the next was directly thereafter, and the final was 5-years post-implementation. These dates coincide with the centralisation of rectal cancer surgery to this centre. Outcomes included unadjusted length of stay and rates of DOSA pre-and post-implementation of the programme. RESULTS: The introduction of a DOSA pathway resulted in a fivefold increase in day of surgery admissions and a related 3-day reduction in average length of stay within a single year of implementation. This further improved in 2016, showing an almost 83% increase (15.90-98.50%) in day of surgery admission and a reduction in average length of stay from 16.4 to 12.4 days when compared to 2011. CONCLUSIONS: Despite an increase in caseload of 54%, an estimated 272 bed days were saved. This demonstrated that DOSA is sustainable and highly effective in tackling the increased inpatient bed demands associated with the growing requirement for elective surgery.
