Auditory findings associated with Zika virus infection: an integrative review

IntroductionPossible associations between Zika virus infection and hearing loss were observed during the epidemic in the Americas.ObjectiveTo describe the auditory alterations, pathogenesis and recommendations for follow-up in individuals with prenatal or acquired Zika virus infection.MethodsBibliographic research conducted in March/2018–April/2019 at the main available databases. Article selection, data extraction and quality evaluation were carried out by two independent reviewers. Studies containing auditory evaluation of patients with congenital or acquired Zika virus infection; and/or hypotheses or evidences on the pathophysiology of auditory impairment associated with Zika virus; and/or recommendations on screening and follow-up of patients with auditory impairment by Zika virus were included.ResultsA total of 27 articles were selected. Sensorineural and transient hearing loss were reported in six adults with acquired Zika virus infection. Of the 962 studied children, 482 had microcephaly and 145 had diagnostic confirmation of Zika virus; 515 of the 624 children with auditory evaluation performed only screening tests with otoacoustic emissions testing and/or automated click-stimuli auditory brainstem response testing. Studies in prenatally exposed children were very heterogeneous and great variations in the frequency of altered otoacoustic emissions and automated click-stimuli auditory brainstem response occurred across the studies. Altered otoacoustic emissions varied from 0% to 75%, while altered automated click-stimuli auditory brainstem response varied from 0% to 29.2%. Sensorineural, retrocochlear or central origin impairment could not be ruled out. One study with infected mice found no microscopic damage to cochlear hair cells. Studies on the pathogenesis of auditory changes in humans are limited to hypotheses and recommendations still include points of controversy.ConclusionThe available data are still insufficient to understand the full spectrum of the involvement of the auditory organs by Zika virus, the pathogenesis of this involvement or even to confirm the causal association between auditory involvement and virus infection. The screening and follow-up recommendations still present points of controversy.     

基于VAS评价右美托咪定在宫颈癌根治术后镇痛及术后快速康复中的临床效果

目的:研究右美托咪定在宫颈癌根治术后镇痛及术后快速康复中的临床应用效果。方法:将2015年7月至2018年7月在本院行宫颈癌根治术的86例患者随机分为对照组和观察组各43例。对照组术后镇痛采用舒芬太尼和格拉司琼，观察组术后镇痛加用右美托咪定。采用视觉模拟评分法（VAS）评价患者术后1 h、6 h、12 h、24 h、48 h疼痛情况，采用Ramesay评分法评价患者不同时间点镇静状况，记录并比较两组患者不同时间点收缩压、舒张压、心率及呼吸频率变化，比较两组患者不良反应发生情况。结果:观察组患者术后6 h、12 h、24 h、48 h VAS评分均明显低于对照组（P＜0.05），Ramesay评分均明显高于对照组（P＜0.05）；观察组和对照组患者术后不同时间点呼吸频率比较，差异无统计学意义，但术后6 h、12 h、24 h观察组患者收缩压、心率均明显低于对照组（P＜0.05），术后1 h、6 h观察组患者舒张压明显低于对照组（P＜0.05）；观察组患者恶心呕吐、高血压发生率较对照组明显减低。结论:右美托咪定用于宫颈癌根治术后镇痛，可以提高镇痛镇静效果，稳定患者血流动力学，有助于术后快速康复。     

A Snapshot of the Guidelines on Vesicoureteral Reflux in Children

The main goal in the management of patients with vesicoureteral reflux (VUR) is the preservation of kidney function by minimizing the risk of pyelonephritis. By defining and analyzing the risk factors for each patient depending on age, sex, grade of reflux, lower urinary tract dysfunction, anatomic abnormalities, and kidney status, it is possible to identify those patients with a potential risk of upper urinary tract infection and resulting renal scarring. This paper gives a brief overview of the European Association of Urology guidelines for the management and treatment of VUR in children. These guidelines are based on the best currently available knowledge and evidence.     

8种寄生虫病例分析

本文报道并分析8例寄生虫病例,其中包括脑裂头蚴病、眼部裂头蚴病、肺吸虫幼虫移行症、肺吸虫病、钩虫病、肝吸虫病、包虫病和广州管圆线虫病各1例。8例寄生虫病均有不同程度的误诊,其中6例在寄生虫抗体筛查检测阳性后得以确诊。因此,寄生虫病应引起临床医生的重视,抗体筛查有助于发现寄生虫病例。     

肿瘤合并感染新冠肺炎患者临床分析及疫情期间肿瘤患者的管理建议

目的:探讨分析肿瘤合并新冠病毒感染患者情况并提出自己的思考与建议。方法:通过统计2020年1月至2020年3月期间纳入的313名本院肿瘤科在新冠疫情期间肿瘤合并感染新冠肺炎患者情况，汇总临床资料，分析患者肺部影像学特点，总结肿瘤合并新冠肺炎病毒感染患者临床特征、预后及转归等，并提出自己建议。结果:科室总共313名患者住院，5名新冠感染患者，新冠病毒肺炎发生率为1.6%，这比之前所报道的武汉市新冠病毒普通人群发生率0.37%要高接近3倍，肿瘤合并新冠患者死亡率接近20%。结论:对于疫情结束初期病房应尽量减少患者非必要往返医院次数，实行肿瘤患者分层管理，加强轻症患者随访，线上管理等；而对于住院患者，则采取缓冲分诊模式，做好病房消毒隔离以及管理，避免感染，减少肿瘤病房新型冠状病毒爆发概率。     

术前预后营养指数对肺癌术后并发症风险的预测价值

目的:探讨术前预后营养指数（prognostic nutritional index，PNI）对肺癌术后并发症风险的预测价值。方法:回顾分析2015年12月至2018年3月于我院行手术治疗的非小细胞肺癌患者180例，收集患者的临床资料以及术后并发症的发生情况，采用Logistic回归分析患者术后并发症的影响因素。结果:多因素Logistic回归分析表明，术前低PNI值是术后并发症Clavien-Dindo评分≥II级的独立危险因素（OR:1.10，95%CI:1.02~1.17，P=0.023）；根据术前PNI值将患者分为三组，分别为PNI≥50组（n=113）、45≤PNI<50组（n=47）、PNI<45组（n=20），各组术后并发症Clavien-Dindo评分≥II级以及Clavien-Dindo评分≥III级发生的比例分别为22.1%、40.4%、40.0%和6.2%、17.0%、25.0%，不同PNI值术后并发症发生率存在显著差异；PNI值可作为术后并发症发生风险及气胸、肺外感染的独立危险因素。结论:PNI值可作为肺癌患者术后并发症风险的有效预测因子。     

敷料更换的不同次数对穿刺引流术后穿刺口感染的影响

目的 研究敷料更换的不同次数对穿刺引流术后穿刺口感染的影响.方法 随机将该院2013年6月—2014年7月收治的100位进行穿刺引流术的患者分为两组,50例为A组,50例为B组. 为A组患者1周更换1次敷料,B组患者1周更换2次敷料. 对两组患者穿刺口感染的情况进行分析比较. 结果 A组患者穿刺口感染的几率显著低于B组(P<0.05),A组患者的病原菌定植率显著低于B组(P<0.05),两组患者导管相关性血流感染率差异无统计学意义(P>0.05). 结论 穿刺引流术后的患者1周更换1次敷料比较合理,既能降低患者术后穿刺口感染的几率,又能降低医护人员的工作量,但要注意在敷料发生松动或者潮湿时也要及时进行更换.     

Initiatives to reduce postoperative surgical site infections of the head and neck cancer surgery with a special emphasis on developing countries

Introduction: Surgery in patients with head and neck cancers is frequently complicated by multiple stages of procedure that includes significant surgical removal of all or part of an organ with cancer, tissue reconstruction, and extensive neck dissection. Postoperative wound infections, termed ‘surgical site infections’ (SSIs) are a significant impediment to head-and-neck cancer surgery and recovery, and need to be addressed.

Areas covered: Approximately 10–45% of patients undergoing head-and-neck cancers surgery develop SSIs. SSIs can lead to delayed wound healing, increased morbidity and mortality as well as costs. Consequently, SSIs need to be avoided where possible, as even the surgery itself impacts on patients’ subsequent activities and their quality of life, which is exacerbated by SSIs. Several risk factors for SSIs need to be considered to reduce future rates, and care is also needed in the selection and duration of antibiotic prophylaxis.

Expert commentary: Head and neck surgeons should give personalized care especially to patients at high risk of SSIs. Such patients include those who have had chemoradiotherapy and need reconstructive surgery, and patients from lower and middle-income countries and from poorer communities in high income countries, who often have high levels of co-morbidity because of resource constraints.
