Objective

To validate and assess the reproducibility of the ISAAC Written Allergic Rhinitis Questionnaire (WARQ) for children aged between 6 and 7 years by telephone contact.

Methods

Observational study through interviews with guardians of children aged 6–7 years using the ISAAC Allergic Rhinitis (AR) module questionnaire in three different phases separated by 2 weeks each: telephone interviews in the first and third contacts and face-to-face interviews, with the same guardian of telephone interviews, in the second contact. Reproducibility was estimated using the Kappa index and validation using the sensitivity and specificity coefficients.

Results

Data from 94 children (48 from the allergic rhinitis Control Group ‒ CG) were analyzed. Reproducibility showed perfect agreement (100%) for the question number 1 – Which refers to the symptoms of AR, ever: “Has your child ever had a problem with sneezing or a runny or a blocked nose when he/she did not have a cold or the flu?” and for the question number 2 – Which refers to current symptoms of AR: “In the past 12 months, has your child had a problem with sneezing or a runny or a blocked nose when he/she did not have a cold or the flu?” A strong agreement was also observed for the question number 3 (κ = 0.871) – it defines the presence of comorbidity of allergic rhinoconjuntivitis “In the past 12 months, has this nose problem been accompanied by itchy-watery eyes?” The validation showed high specificity (≥76.7%) and sensitivity (≥98%) for all questions, except for the ones related to seasonality and intensity of symptoms.

Conclusions

Our results showed that the ISAAC AR module questionnaire by telephone interviews has good reproducibility and high agreement with the clinical diagnosis of AR. It may be an appropriate alternative tool in epidemiological studies of childhood AR, especially in periods of social isolation, such as Coronavirus pandemic.

Objectives

To compare Anatomy-Based Fitting (ABF) vs. Default Fitting (DF) in terms of music perception and music enjoyment in CI users.

Methods

CI users ≥ 18 years implanted with a Synchrony ST Flex28 (MEDEL) with at least 12 months of experience with either ABF or DF, with good speech tests outcomes (≥ 65% disyllables) were enrolled. Music tasks were assessed with “Discovery” level of Meludia online interactive music tool, which includes Rhythm (beat count), Spatialization (differentiating between lower and higher notes), Stable/unstable (perception of stability or instability), Melody (ascendant or descendant), and Density (presence of one or multiple simultaneous sounds). Each task consists of five levels of difficulty. Participants were allowed a maximum of 4 attempts to complete a level. The Music-Related Quality of Life (MuRQoL) and the Munich Music (MUMU) questionnaires evaluated music background.

Results

Twenty CI users took part: 10 using ABF and 10 DF. There were no significant differences in age at implantation (53.2 ± 15.0 vs. 53.8 ± 14.5y), time since surgery (1.8 ± 0.5 vs. 2.4 ± 1.5y), or the percentage of disyllables in silence (68.0 ± 8.0 vs. 77.3 ± 11.5%) between groups. Regarding Meludia scores, differences were observed between both groups in Density: ABF had better mean scores when completing the level in only one attempt (8.7 ± 2.5 vs. 4.6 ± 3.1, p = 0.016) and required fewer restarts to complete the five levels (6.6 ± 1.6 vs. 9.3 ± 2.3; p = 0.009). Furthermore, the fifth level of Density was successfully completed by 60% of patients with ABF, while none of the patients with DF achieved this (p = 0.003). The scores obtained in MuRQoL were similar between ABF and DF groups. In a similar way, the MUMU showed no differences in terms of frequency and music importance.

Conclusions

ABF demonstrates specific advantages in certain musical tasks, specifically in processing multiple sounds simultaneously. Further studies are necessary to explore additional benefits of ABF in musical skills in CI users. NCT05319678.

目的比较基于解剖的装配（ABF）与默认装配（DF）对 CI 用户音乐感知和音乐享受的影响：方法：招募年龄≥ 18 岁、植入 Synchrony ST Flex28 (MEDEL)、使用 ABF 或 DF 至少 12 个月、语音测试结果良好（双音节率≥ 65%）的 CI 用户。音乐任务使用 Meludia 在线互动音乐工具的 "发现 "级别进行评估，包括节奏（节拍计数）、空间化（区分低音和高音）、稳定/不稳定（感知稳定或不稳定）、旋律（升调或降调）和密度（同时出现一个或多个声音）。每项任务由五个难度级别组成。参与者最多可尝试 4 次完成一个级别。音乐相关生活质量（MuRQoL）和慕尼黑音乐（MUMU）问卷对音乐背景进行了评估：结果：20 名 CI 用户参加了调查：10 人使用 ABF，10 人使用 DF。植入时的年龄（53.2 ± 15.0 岁 vs. 53.8 ± 14.5 岁）、手术后的时间（1.8 ± 0.5 岁 vs. 2.4 ± 1.5 岁）或静音时的双音节百分比（68.0 ± 8.0% vs. 77.3 ± 11.5%）在各组间无明显差异。关于 Meludia 分数，两组之间在密度上存在差异：ABF 组在只尝试一次就完成该级别时平均得分更高（8.7 ± 2.5 vs. 4.6 ± 3.1，p = 0.016），在完成五个级别时需要重新开始的次数更少（6.6 ± 1.6 vs. 9.3 ± 2.3；p = 0.009）。此外，60% 的 ABF 患者成功完成了第五级密度，而 DF 患者则无一成功完成（p = 0.003）。ABF 组和 DF 组的 MuRQoL 得分相似。同样，MUMU 在频率和音乐重要性方面也没有显示出差异：结论：ABF 在某些音乐任务中，尤其是在同时处理多种声音方面表现出了特殊的优势。有必要开展进一步研究，探索 ABF 对 CI 用户音乐技能的其他益处。NCT05319678.证据等级：3级。

Objective

To identify risk factors for Lymph Node Metastasis (LNM) in pT3-4 Laryngeal Squamous Cell Carcinoma (LSCC) patients with negative margins, and develop a nomogram to predict LNM risk.

Methods

872 patients were divided into training (2010–2014) and validation (2015–2016) cohorts. Univariate and multivariate analyses identified LNM risk factors. A nomogram incorporating significant factors was developed in the training cohort.

Results

Smoking history, maximal tumor diameter ≥3.0 cm, depth of tumor invasion >1.0 cm, and supraglottic tumor location were significantly associated with LNM on multivariate analysis. A predictive nomogram incorporating these factors showed good discrimination (C-index > 0.7) in both cohorts. Patients were stratified into low, moderate and high-risk subgroups based on total risk scores.

Conclusions

A LNM risk prediction model and risk grouping system was established, which may aid treatment selection for pT3-4 LSCC patients. The model and algorithm could help optimize neck management for this high-risk patient population.

目的方法：将872例患者分为训练组（2010-2014年）和验证组（2015-2016年）。单变量和多变量分析确定了LNM风险因素。在训练队列中绘制了包含重要因素的提名图：结果：在多变量分析中，吸烟史、肿瘤最大直径≥3.0厘米、肿瘤侵犯深度>1.0厘米和声门上肿瘤位置与LNM显著相关。包含这些因素的预测提名图在两个队列中均显示出良好的区分度（C 指数 > 0.7）。根据总风险评分将患者分为低、中和高风险亚组：建立了LNM风险预测模型和风险分组系统，可帮助pT3-4 LSCC患者选择治疗方法。该模型和算法有助于优化这一高风险患者群体的颈部管理：

Objective

To understand the characteristics of cervical lymph node metastasis in Oropharyngeal Squamous Cell Carcinoma (OPSCC) patients, explore the risk factors for lymph node metastasis, and its impact on prognosis.

Methods

Retrospective cohort study. Statistical analysis of the relationship between various clinicopathological factors and lymph node involvement, as well as the independent risk factors affecting lymph node metastasis and their impact on prognosis.

Results

The cervical lymph node metastasis rate in this group was 89.2%, with the palatine tonsils and base of the tongue more prone to cervical lymph node metastasis (p = 0.007); lower pathological differentiation of OPSCC was more likely to develop cervical lymph node metastasis (p = 0.017). The P16 protein positive rate in this group was 58.8%. P16 protein expression did not affect the incidence rate of cervical lymph node metastasis in OPSCC (p = 1.000) but influenced the risk of multiple lymph node metastases (p = 0.011) and was a risk factor affecting the prognosis of OPSCC (p = 0.003). However, the lymph node metastasis status did not affect the survival time of OPSCC patients.

Conclusion

In the Shanxi region of China, HPV-related OPSCC accounts for a higher proportion; OPSCC has a high rate of cervical lymph node metastasis, but lymph node metastasis does not significantly increase the mortality risk of OPSCC patients, which may be related to the unique characteristics of HPV-related OPSCC.

Retrospective cohort study.

目的了解口咽鳞癌（OPSCC）患者颈淋巴结转移的特征，探讨淋巴结转移的风险因素及其对预后的影响：方法：回顾性队列研究。统计分析各种临床病理因素与淋巴结受累的关系，以及影响淋巴结转移的独立危险因素及其对预后的影响：本组患者的颈淋巴结转移率为89.2%，其中腭扁桃体和舌根部更容易发生颈淋巴结转移（P=0.007）；病理分化较低的OPSCC更容易发生颈淋巴结转移（P=0.017）。该组患者的P16蛋白阳性率为58.8%。P16 蛋白表达不影响 OPSCC 的宫颈淋巴结转移发生率（p=1.000），但影响多淋巴结转移的风险（p=0.011），并且是影响 OPSCC 预后的风险因素（p=0.003）。然而，淋巴结转移状态并不影响OPSCC患者的生存时间：结论：在中国山西地区，HPV相关OPSCC所占比例较高；OPSCC的宫颈淋巴结转移率较高，但淋巴结转移并不会显著增加OPSCC患者的死亡风险，这可能与HPV相关OPSCC的特殊性有关。证据级别Ⅳ：回顾性队列研究。

Objectives

This study aimed to clarify the impact of hypertonic solutions on various outcomes, including persistence or reduction of nasal crusts, polypoid edema, and postoperative inflammatory symptoms.

Methods

We searched PubMed, Embase, and Cochrane Central Register of Controlled Trials for studies comparing hypertonic with isotonic saline irrigation after FESS in adult patients with Chronic Rhinosinusitis (CRS). Outcomes were polypoid mucosa, nasal crusts, and variation from the baseline of Sino-Nasal Outcome Test (SNOT) 20/22 and Visual Analog Scale (VAS). For statistical analysis, we used RevMan 5.4.1, and assessed heterogeneity with I² statistics.

Results

We included a total of 479 patients from 7 studies. In the hypertonic saline group, there was a reduction in the nasal crust Risk Ratio (RR) (RR = 0.65; 95% CI 0.49 to 0.87; p = 0.004; I² = 0%) after 30–45 days and severe crusts at 14–21 days (RR = 0.59; 95% CI 0.38 to 0.91; p = 0.02; I² = 0%). Additionally, the persistence of polypoid mucosa was lower in the intervention arm (RR = 0.53; 95% CI 0.43 to 0.65; p < 0.00001; I² = 0%) after 14–21 days. In the symptomatic evaluation hypertonic saline group showed an improvement in postoperative symptoms by a VAS Mean Difference (MD) (MD = −5; 95% CI −5.77 to −4.24; p < 0.00001; I² = 0%) and a SNOT 20/22 Standard Mean Difference (SMD) (SMD = −1.65; 95% CI −2.7 to −0.61; p = 0.002; I² = 93%) reduction from baseline in 30–45 days after the surgery.

Conclusion

Hypertonic saline showed a superior improvement in postoperative evaluation by means of nasal crusting, mucosal healing aspect, and nasal inflammatory symptoms compared with isotonic saline irrigation.

本研究旨在阐明高渗溶液对各种结果的影响，包括鼻痂、息肉样水肿和术后炎症症状的持续或减轻。方法我们检索了 PubMed、Embase 和 Cochrane Central Register of Controlled Trials 等文献，比较了慢性鼻窦炎（CRS）成人患者 FESS 术后高渗和等渗生理盐水灌洗的研究。研究结果包括息肉状粘膜、鼻腔结痂、中鼻结果测试（SNOT）20/22 和视觉模拟量表（VAS）与基线的差异。我们使用 RevMan 5.4.1 进行了统计分析，并用 I2 统计量评估了异质性。在高渗盐水组中，30-45 天后鼻痂风险比 (RR) 降低（RR = 0.65；95% CI 0.49 至 0.87；p = 0.004；I2 = 0%），14-21 天后严重鼻痂风险比降低（RR = 0.59；95% CI 0.38 至 0.91；p = 0.02；I2 = 0%）。此外，14-21 天后，干预组的息肉状粘膜持续性较低（RR = 0.53；95% CI 0.43 至 0.65；p < 0.00001；I2 = 0%）。在症状评估中，高渗盐水组的术后症状有所改善，VAS平均差（MD）（MD = -5; 95% CI -5.77 to -4.24; p < 0.00001; I2 = 0%）和SNOT 20/22标准平均差（SMD）（SMD = -1.65; 95% CI -2.7 to -0.结论与等渗盐水灌洗相比，高渗盐水通过鼻腔结痂、粘膜愈合方面和鼻腔炎症症状对术后评估有更好的改善作用。

Objective

This study aims to evaluate the cognitive performance in adults with hearing loss and to identify associations between clinical characteristics of hearing loss and cognitive outcomes.

Methods

In this cross-sectional analytical observational study, adults with hearing loss underwent the Mini-Mental State Examination (MMSE), following the collection of their clinical and audiometric data.

Results

Among 134 evaluated individuals, a majority reported a progressive onset (91.04%) and bilateral nature (87.31%) of hearing loss, with moderate hearing loss being the most common (41.04%). Sensorineural hearing loss was prevalent in 76.12% of cases, with presbycusis identified as a primary etiology in 37.31%. Comorbidities were reported in 61.19% of participants, with 16.42% using benzodiazepines or antidepressants regularly. Symptoms included imbalance (33.58%), vertigo (42.54%), and tinnitus (73.88%). Notably, a sudden onset of hearing loss and imbalance complaints were linked to a higher likelihood of subnormal MMSE performance. Analysis revealed varied cognitive domain performances associated with different clinical characteristics of hearing loss.

Conclusion

Various aspects of hearing loss, such as bilateral and sensorineural types, and the presence of symptoms like tinnitus and vertigo, significantly influence cognitive performance. Specifically, sudden onset hearing loss and imbalance complaints are associated with poorer overall cognitive outcomes in the MMSE. These findings underscore the importance of considering the diverse impacts of hearing loss characteristics on cognitive functions.

Objectives

Several studies have evaluated the prognostic significance of Perineural Invasion (IPN) in laryngeal cancer; however, the results are non-conclusive. Therefore, we conducted a meta-analysis aiming to identify the prognostic value of IPN in laryngeal cancer.

Methods

A literature review was performed, searching MedLine via PubMed, Scielo, Lilacs, Cochrane and Websco. RevMan 5.4 was used for the statistical analysis.

Results

A total of 19 laryngeal cancer studies were included. The results indicate that IPN in laryngeal cancer shows 2-year survival with RR 0.71 (0.59‒0.86); disease-free survival RR 0.51 (0.14–1.95); and locoregional recurrence RR 1.71 (1.25–2.35).

Conclusion

IPN is a negative prognostic factor in laryngeal cancer.

研究目的有几项研究评估了喉癌神经周围侵犯（IPN）的预后意义，但结果尚无定论。因此，我们进行了一项荟萃分析，旨在确定 IPN 在喉癌中的预后价值：方法：通过PubMed、Scielo、Lilacs、Cochrane和Websco检索MedLine，进行文献综述。统计分析使用 RevMan 5.4：结果：共纳入 19 项喉癌研究。结果显示，IPN在喉癌中的2年生存率为RR 0.71（0.59-0.86）；无病生存率为RR 0.51（0.14-1.95）；局部复发率为RR 1.71（1.25-2.35）：结论：IPN是喉癌的不良预后因素。

Objective

This study describes the training experience with the Versius Robotic System (CMR Surgical) for Transoral Robotic Surgery (TORS), the setup of the robot and its applicability in a human case.

Methods

A model mannequin with anatomical characteristics simulating the TORS working space was used for training purposes. Optimal docking, positioning of robotic arms and placement of instruments were defined using the mannequin. A human patient was selected based on the inclusion criteria, and a standardized protocol for robotic techniques was developed. The surgical procedure was conducted in accordance with ethical guidelines.

Results

The synthetic polymer mannequin mimicking human tissues and anatomy was used to define the robot set up for TORS. The patient was indicated for bilateral tonsillectomy due to recurrent episodes of tonsillitis. Bipolar Maryland and monopolar scissors were used. The procedure was uneventful. The patient remained hospitalized for 1 day and returned to work activities within 6-days, with no complications.

Conclusion

The specialized mannequin proved to be effective in the simulation, training proposal and set up standardization. Furthermore, the Versius robot was found to be safe and achieved excellent results during surgery. Despite being very promising, the Versius system is still in its developmental phase and requires larger-scale samples for a more comprehensive evaluation.
