3mN/s (n = 5), respectively (mean ± SD, p < 0.02). For mobilization of the mobile footplate, maximal forces during mobilization were similar during manual and robot-assisted manipulations, respectively 12 ± 2.5 (n = 6) and 19 ± 7.6mN (n = 7). Compared with mobilization of a mobile footplate, mobilization of a fixed footplate required ~ 60 and ~ 27 times higher maximal forces for manual and robot-assisted manipulations, respectively 724 ± 366.4 and 507 ± 283.2mN. Yank was twice as high during manual manipulation compared to robot-assisted manipulation (p < 0.05).

Robot-assisted manipulation of the ossicular chain was reliable. Our anatomical model of otosclerosis was successfully developed requiring higher forces for stapes mobilization.

The purpose of the study was to know whether the wideband absorbance measurements can be a useful tool to identify ears with otosclerosis. The present study analyzed WBA measurements and highlighted its effectiveness in identifying ears with otosclerosis and differentiating from healthy normal ears.

The study included 42 ears with otosclerosis which were compared with an equal sample size of healthy normal ears. WBA across frequencies and wideband average absorbance (375-2000Hz) at the peak and ambient pressure, and resonance frequency were measured and analyzed.

Results showed that WBA levels increased with an increase in frequencies up to 2000Hz and decreased thereafter, both in the otosclerosis and healthy normal ears. The mean WBA in the otosclerosis group was significantly lower in the 250-2000Hz frequency range than in the healthy normal ear group. The WBA values at ambient pressure reduced significantly up to 500Hz for the healthy normal ear group and 1500Hz for otosclerosis group, compared with peak pressure. Further, the analysis of wideband average absorbance at ambient pressure showed reduced absorbance (0.35) and higher resonance frequency (1350.33Hz) in the otosclerosis group compared with the healthy normal ear group (0.60 and 930.14Hz, respectively). ROC analysis indicated that WBA is suitable for identifying otosclerotic ears and also in differentiating from healthy normal ears based on WBA values from 250 to 1500Hz. High diagnostic values of WBA (> 90% sensitivity and specificity) were observed at a frequency of 1000Hz.

The inclusion of WBA into clinical routine test procedures could be a useful tool for detecting otosclerosis. Further research is required to validate its clinical use in combination with other middle ear measures.

To study the psychoacoustic and audiological characteristics of patients with chronic subjective tinnitus and provide basis for the personalized diagnosis and treatment of tinnitus through a single tinnitus multielement integration sound therapy (T-MIST) and analysis of efficacy preliminarily.

145 patients with tinnitus were assessed by systematic medical history collection, professional examination of otolaryngology, audiology examination, full precision test (FPT), residual inhibition test (RIT), tinnitus handicap inventory (THI) and visual analog scale (VAS) annoyance. The correlation among factors was performed.

The frequency of tinnitus was correlated with the frequency of maximum hearing loss (P < 0.05). The loudness of tinnitus was correlated with the loudness of maximum hearing loss (P < 0.05). In this study, T-MIST was used to treat tinnitus. After treatment, tinnitus alleviated VAS annoyance (P < 0.05). The results of RIT were correlated with the effect of T-MIST (P < 0.05).

There was a correlation between tinnitus and hearing loss. The RIT may indicate the effectiveness of acoustic therapy in patients. The FPT can find the hidden hearing loss without display on routine pure tone audiometry, so as to provide a clinical reference for the detection of early hearing loss in tinnitus patients.

The SARS-COV-2 virus has more than just an infectious role to play in the society. The rapid spread has also led to significant personal, professional, financial and economic recession globally. Health care professionals are getting seriously compromised due to these issues. No published data are available on the indirect effects of COVID-19 on high-risk medical specialties. Otorhinolaryngology is considered as one such specialty. Hence, we designed a national survey to address these issues.

A google questionnaire was sent to all the otorhinolaryngologists in Czech Republic with the help of the Czech Society of Otorhinolaryngology and Head and Neck Surgery to evaluate the problems they encountered during the first wave of COVID-19. learn more Personal, professional and financial losses were also addressed. Online access to the survey was from 15th April 2020 to 26th April 2020.

The psychosomatic indirect impact of the disease affected female doctors than males. Burnout syndrome was the most commonly reported problem. Around 44.75% of all doctors had a combination of health, financial and economic as well as professional development and educational issues. Doctors from private practices faced higher financial losses.

Our study showed that personal, professional and financial disturbances amongst doctors can lead to more serious consequences. With the lack of drastic measures in improving the support system for healthcare workers, the healthcare systems will fail quickly. Adequate support should be made mandatory by health authorities.

To evaluate the role of elective neck dissection (END) and of adjuvant radiation (aRT) in polymorphous adenocarcinoma (PAC), previously known as polymorphous low-grade adenocarcinoma (PLGA).

Retrospective cohort study of patients in the National Cancer Database with a histology of PAC (coded as PLGA) at a head and neck site diagnosed between 2004 and 2015. Multivariable Cox proportional hazard modeling was used to assess overall survival in the overall population, and in sub-analyses of clinically N0 disease, positive resection margins, and late stage disease.

A total of 922 patients [66.8% female; mean (SD) age, 60.9 (13.9) years] met inclusion criteria. 74.7% of patients received surgery alone, and 18.0% received surgery and aRT. Only 7.6% of patients with clinically N0 disease received an END, with 10.6% of these having at least one positive node. END did not have a survival benefit compared to no END [HR 1.28 (0.61-2.68)]. Compared to surgery alone, aRT did not have significantly increased survival in the overall population or in late stage [HR 0.68 (0.39-1.19) and HR 0.46 (0.18-1.22), respectively]. On sub-analysis of patients with positive resection margins, aRT had a significant survival benefit compared to surgery alone [HR 0.37 (0.14-0.99)].

PAC is a rare, slow-growing malignant tumor typically treated with surgical excision, with undefined indications for END or aRT. Our findings show END to not have a benefit to overall survival. In patients with positive resection margins, there was a survival benefit for aRT.

Evidence is accumulating that Staphylococcus aureus plays an important role as a disease modifier in upper and lower airway disease. We aimed to assess the association of staphylococcal enterotoxins (SEs) with allergic multimorbidity as well as the severity of chronic rhinosinusitis.

We retrospectively reviewed the medical records of 97 subjects aged 6years or older between March 2018 and June 2019 and analysed symptom scores, computed tomography scores, serum IgE levels to SEs, serum total and specific IgE levels to inhalant allergens. To evaluate eosinophilic chronic rhinosinusitis (ECRS), we used refractory ECRS score from the Japanese epidemiological survey.

Of the 97 patients enrolled, 29 (29.9%) were non-sensitised, 33 (34.0%) were mono-sensitised, and 35 (36.1%) were poly-sensitised. Sensitisation to SEs was closely associated with poly-sensitisation to inhalant allergens. SE-sensitised participants had higher median values for total and specific IgE levels to inhalant allergens than did non-SE-sensitised participants. SE sensitisation was associated with allergic multimorbidity and severe allergic diseases, such as ECRS.

This preliminary study suggested that sensitisation to SEs may play a role in the initiation of type-2 inflammatory responses, such as allergic rhinitis, ECRS, and allergic multimorbidity. Furthermore, sensitisation to SEs correlated with the severity of ECRS.

We reviewed the available literature on patients with lung cancer undergoing either uniportal (UVATS) or multiport video-assisted thoracoscopic surgery (MVATS).

Original research studies that evaluated perioperative and long-term outcomes of UVATS versus MVATS were identified, from January 1990 to April 2020. The perioperative, along with the oncologic and long-term survival outcomes, were calculated according to either a fixed or a random effect model, appropriately. The Q statistics and I

statistic were used to test for heterogeneity among the studies.

Twenty studies were included, incorporating a total of 1,469 patients treated with UVATS and 3,231 treated with MVATS. The incidence of complications was lower in patients treated with UVATS [OR 0.76 (95% CI 0.62, 0.93); p = 0.008]. The chest tube duration was significantly lower in the UVATS group (WMD -0.63 [95% CI -1.03, -0.23]; p = 0.002). Length of hospital stay (L.O.S.) was also lower in the UVATS patient group (WMD -0.54 [-0.94, -0.13]; p = 0.009), along with postoperative pain [WMD -0.
