Aural tuberculosis at the start of the 21st century. Literature review according to SWiM guidelines. Part 2: Treatment

ObjectivesSystematic review of the scientific literature dedicated to treatment modalities and results for aural tuberculosis published since the start of the 21^st century.Material and methodsSearch of the Medline, Cochrane and Embase databases for the period 2000 - 2020. Selection of articles in English, French and Spanish devoted to clinical cases and series documenting treatment of auricular tuberculosis. Extraction of data on pre-established files documenting treatment modalities and results. Reading of articles by two authors. Analysis performed according to SWiM guidelines, evaluating cure, tuberculosis-related death, treatment-related complications, improvement in facial palsy, and hearing sequelae rates.ResultsOne hundred and twenty eight articles: 118 case reports (159 patients) and 10 cohorts (177 patients) from 42 countries were analyzed. Female/male sex ratio was 1.2 with ages ranging from 1 month to 87 years. Medical treatment consisted in 5 to 24 months’ antitubercular antibiotic treatment using 2 to 8 antibiotics. Mastoidectomy, tympanoplasty and facial nerve decompression were associated to medical treatment in 64.7%, 17.4% and 6.2% of cases, respectively. Overall rates of cure, death, treatment-related complications, facial sequelae and hearing sequelae were 96.8%, 2%, 9.5%, 35.8% and 75.5%. In case reports, BCG vaccination did not appear to protect against facial palsy and severe intracranial complications (P > 0.6). There was no significant correlation (P > 0.3) between death and the clinical variables tested, and facial nerve decompression did not appear to influence outcome for facial function (P = 0.4).ConclusionMedical treatment is very effective but not without risk of death, complications and sequelae. It is the same as for pulmonary tuberculosis. Indications for and benefit of major auricular surgery during medical treatment deserve further studies.     

Correlation between cow’s milk protein allergy and otitis media: a systematic review

ObjectivesTo review the evidence pertaining to the association between cow’s milk protein allergy and recurrent acute otitis media and otitis media with effusion.MethodsThe CENTRAL, Web of Science, EMBASE, MEDLINE, LILACS databases, and gray literature were searched.ResultsFour studies were included, identifying the prevalence rates: 0.2% of delayed speech due to chronic otitis media with effusion in 382 children with cow’s milk protein allergy, 10.7% of cow’s milk protein allergy in 242 children who underwent ENT procedures, 40% of cow’s milk protein allergy in 25 children with recurrent otitis media with effusion and higher tendency to otitis media in children with cow’s milk protein allergy of 186 children (1.5 + 0.6 vs. 0.4 + 0.1; p < 0.1).ConclusionConsidering the characteristics and methodological variations of the identified studies, it is not possible to state that there is reliable evidence of an association between cow’s milk protein allergy and otitis media.     

Implementation of a Semistructured Clinical Event Documentation Tool for Acute Adverse Contrast Reactions

PurposeTo improve the efficiency and accuracy of clinicians documenting acute clinical events related to contrast agent administration using a web browser–based semistructured documentation support tool.MethodsA new tool called Contrast Incident Support and Reporting (CISaR) was developed to enable radiologists responding to contrast reactions to document inciting contrast class, type of event, severity of contrast reaction, and recommendation for future contrast use. Retrospective analysis was conducted of all CT and MRI examinations performed between February 2018 and December 2019 across our hospital system with associated contrast reaction documentation. Time periods were defined as before tool deployment, early adoption, and steady-state deployment. The primary outcome measure was the presence of event documentation by a radiologist. The secondary outcome measure was completeness of the documentation parameters.ResultsA total of 431 CT and MRI studies with reactions were included in the study, and 50% of studies had radiologist documentation during the pre-CISaR period. This increased to 66% during the early adoption period and 89% in the post-CISaR period. It took approximately 9 months from the introduction of CISaR to reach full adoption and become the main method for adverse contrast reaction documentation. The percentage of radiologist documentation that detailed provoking contrast agent class, severity of reaction, reaction type, and future contrast agent recommendation all significantly increased (P < .0001), with greater than 95% inclusion of each element.ConclusionThe implementation of a semistructured electronic application for adverse contrast reaction reporting significantly increased radiologist documentation rate and completeness of the documentation.     

超声造影规范化护理专家共识

为了实现超声对比剂（也称超声造影剂）高效、合理、安全、规范化输注，国内相关医护专家总结了国内外文献证据及临床经验，按照循证医学原则充分讨论后，制订了该共识，旨在为我国超声对比剂安全输注的规范化和标准化提供参考意见。共识介绍了超声对比剂的应用现状和安全性、相关法规与流程，造影前、中、后的规范化护理，并提出16条推荐意见。提出目前国内批准上市使用的超声对比剂安全性高，建议医护人员根据最新说明书或专家共识进行配药和给药，并从造影室管理、风险预案、人员资质等方面予以规范。     

中性粒细胞/淋巴细胞比值与冠状动脉造影后造影剂肾病的相关性分析

【目的】探讨中性粒细胞/淋巴细胞比值(NLR)与冠状动脉造影(CAG)后造影剂肾病(CIN)的相关性。【方法】以本院心内科收治的行CAG检查的患者125例为研究对象。根据是否发生CIN,将125例患者分为CIN组和非CIN组。比较两组的基线资料,采用多因素logistic逐步回归分析筛选CIN的独立危险因素,采用受试者工作曲线(ROC)分析NLR比值预测CIN的价值。【结果】125例患者发生CIN共23例,发生率为18.4%。与非CIN组比较,CIN组患者年龄大,糖尿病比例高,尿素氮、血肌酐、尿β2微球蛋白、C反应蛋白以及NLR比值均明显升高(P<0.05),肾小球滤过率(GFR)明显降低(P<0.05),造影剂用量明显增加(P<0.05)。多因素logistic逐步回归分析显示:高龄、糖尿病、基础肾功能不全、血肌酐、C反应蛋白、NLR比值、造影剂用量是发生C1N的独立危险因素(P<0.05)。当cutoff取6.5,NLR预测CIN的曲线下面积为0.865,灵敏度为85.9%,特异度为83.4%。【结论】NLR比值≥6.5时是发生CIN的独立危险因素,对于预测CIN有较高的价值。
