COVID-19 is a global pandemic that is wreaking havoc with the health and economy of much of human civilization. In this document from the American Autonomic Society, we identify the potential risks of exposure to patients, physicians, and allied healthcare staff. We provide guidance for conducting autonomic function testing safely in this environment.Recently, hybrid glenoid components have been developed, consisting of cementless highly porous metal central peg, monoblock keel or cage along with cemented backside polyethylene surface. The aims of this study were twofold (1) to determine the revision and complication rates of hybrid glenoid components, consisting of porous metal pegs or coatings attached to the polyethylene, for aseptic loosening in TSA and (2) to evaluate the rate of radiolucent lines in patients who underwent TSA with hybrid glenoid components consisting of porous metal pegs or coatings attached to the polyethylene. The US National Library of Medicine (PubMed/MEDLINE), EMBASE and the Cochrane Database of Systematic Reviews were queried for publications utilizing the following keywords "hybrid" OR "bone-ingrowth" OR "bone ingrowth" AND "TSA" OR "total" AND "shoulder" AND "arthroplasty" OR "replacement". Five articles were included for analysis (470 operated shoulders, mean follow-up 47.5 months). The overall weighted mean modified methodology Coleman score was 51.2/100, indicating a moderate level of overall methodological quality. The survival rate of hybrid glenoid components was 97.4% (458 out of 470 cases), while the rate of glenoid-related complications was 2.8% (13 cases). Finally, there were 54 cases (out of 313 reported; 17.3%) with glenoid radiolucency (none of them required revision). TSA with hybrid fixation glenoid components was associated with high survivorship and low rate of glenoid component-related complications at 4 years mean follow-up. In addition, there was limited evidence to show that the short- to mid-term outcome of TSA using hybrid glenoid components is not inferior to the outcome of cemented all-polyethylene glenoid components.Purpose This paper aims to report the impact of COVID-19 outbreak on Emergency Ear nose and Throat (ENT) activity, in Lombardy (Italy), during COVID-19 pandemic. Methods The number of accesses to Emergency Department requiring ENT consultations between February 21st and May 7th, 2020, was retrospectively collected, along with the conditions treated. Data were stratified in 1-week time spans, to evaluate the evolving trends during the on-going epidemic and a comparison with the two previous years was performed. Results A significant reduction in the number of consultations performed during the pandemic was observed, as high as - 91% compared to the same period of 2018. Conclusion Multiple reasons can explain such a reduction of Emergency ENT consultations, not least the fear of potentially being infected by SARS-CoV-2 by while accessing the hospital. The analysis performed might be useful as a starting point for a future reorganization of first aid consultations once the epidemic will be resolved.Purpose Differences in the definition and classification of cholesteatoma hinders comparing of surgical outcomes of cholesteatoma. Uniform registration is necessary to allow investigators to share and compare their findings. For many years surgical cholesteatoma procedures were divided into two main groups canal wall up mastoidectomy (CWU) and canal wall down mastoidectomy (CWD). Recently, mastoid obliteration can be added to both procedures. selleck chemicals Because of great variation within these main groups, the International Otology Outcome Group (IOOG) proposed the new SAMEO-ATO classification system to categorize tympanomastoid operations. The aim of our study was to correlate the mastoid bone extirpation (M-stage) with the contemporary (CWU, CWD with or without obliteration) system. Methods Demographic characteristics and type of performed surgery were registered for 135 cholesteatoma patients from sixteen hospitals, both secondary and tertiary care institutions, across the Netherlands. In addition, the surgical reports were collected, retrospectively classified according to the contemporary system and the new system and compared. Correlations of the outcomes were calculated. Results In total, there were 112 CWU and 14 CWD (both with or without obliteration) suitable for correlation analysis. Z test for correlation between the M-stage and CWU procedure was significant for M1a and M1b procedure and significant for M2c with the CWD procedure. Conclusion The newly proposed SAMEO-ATO classification seems to be more detailed in the registration of surgical procedures than surgeons currently are used to. All M-stages of the SAMEO-ATO system are correlating well to the standard CWU and CWD except one 'in between' M-stage.Objective To present and analyse the radiological findings, surgical findings, pre-implantation and post-implantation speech and hearing outcomes of nine children with SMS Type III cochleovestibular malformation. Study design Retrospective case series of nine children with pre-lingual profound sensorineural hearing loss who underwent cochlear implantation (Jan 2012 to July 2019). These children had been classified as Type III malformation according to the SMS Classification of cochleovestibular anomalies. Facial nerve anomalies, CSF leaks and any other significant surgical finding were noted. Meaningful Auditory Integration Scale (MAIS) was used to report the child's pre-operative and two-year post-implantation auditory and speech abilities. Any significant improvement was assessed using the Wilcoxon signed rank test. P value less then 0.05 was considered significant. Results Out of nine patients, five patients sustained CSF gushers, while three patients had mild CSF leak, which were plugged adequately. No facial nerve anomalies were encountered. Post-op course was uneventful for all nine patients. MAIS scores at a two-year follow-up showed significant statistical improvement (P less then 0.05) when compared to pre-operative scores. Conclusion Cochlear implant is the treatment of choice for children with type III cochleovestibular malformation. There are significant auditory and speech improvements expected. However, the surgeon should bear in mind the risk of CSF leak and subsequent meningitis.
