You have a question, or want to find out current perceptions about a subject, and a comprehensive literature search does not give the answer. A questionnaire or survey, if appropriately designed and administered, can be an easy and efficient way to collect data. However, a well-designed tool is essential to provide meaningful answers.Guidance on good questionnaire design is available.1–4 This can be framed around three simple steps: preparation—evaluation—delivery. Analysis and interpretation are the final stages of completing the research.Is a survey method the most appropriate research tool to answer the question? Questionnaires are useful to investigate opinions or attitudes of a population. If a questionnaire is chosen as the research tool, the next step is to identify whether a validated instrument already exists. If a tool needs to be designed, what format would be of greatest value in answering the enquiry; a structured interview or a self-completed written form? The latter can gather a large amount of rich data, while the former provides a deeper understanding through semistructured questioning.3Self-completed questionnaires require careful construction with clear articulation of purpose. Their success depends strongly on format as well as the wording; use an attractive, easy to navigate presentation and ensure the length is kept as short as possible. Consider whether to include open or closed questions, or a combination of both. Questions should only include a single point, written unambiguously and contained within short sentences.

你有一个问题,或者想要了解当前对某个主题的看法,而全面的文献检索并不能给出答案。问卷或调查,如果设计和管理得当,可以是一个简单和有效的方式来收集数据。然而,一个设计良好的工具对于提供有意义的答案至关重要。关于良好问卷设计的指导是可用的。这可以分为三个简单的步骤:准备-评估-交付。分析和解释是完成研究的最后阶段。调查方法是回答这个问题最合适的研究工具吗?调查问卷对调查民众的意见或态度很有用。如果选择问卷作为研究工具,下一步是确定是否已经存在有效的工具。如果需要设计一个工具,什么格式在回答查询时最有价值;是结构化面试还是自行填写的书面表格?后者可以收集到大量丰富的数据,而前者通过半结构化的提问提供了更深层次的理解。3 .自填问卷需要精心构建,目的明确。它们的成功很大程度上取决于格式和措辞;使用一个有吸引力的,易于浏览的演示文稿,并确保长度尽可能短。考虑是否包括开放式或封闭式问题,或两者结合。问题应该只包含一个点,写得明确,用短句表达。措辞应该适合你的调查对象,避免术语,以减少潜在的混淆。封闭式问题可以提供大量易于处理的(通常是数字)数据。开放式问题,比如免费的……

When any patient uses a medicine, it has the ability to cause a noxious and unintended response known as an ‘adverse drug reaction’ (ADR). A drug allergy is defined as an ADR with specific clinical features compatible with an immunological mechanism that re-occurs on re-exposure to that offending drug. Sometimes, it can be a challenge to decide from the clinical history alone as to whether a drug reaction is allergic or not without the need for further investigations.In September 2014, the National Institute for Health and Care Excellence (NICE) published a guideline entitled ‘Drug allergy: diagnosis and management of drug allergy in adults, children and young people’.1 This was developed due to variation in provision of care for people with a suspected drug allergy and to optimise best practice advice on the diagnosis, documentation and communication of drug allergy. Our focus here will be on the recommendations for children and young people.The British Society for Allergy and Clinical Immunology (BSACI) guidelines for the management of drug allergy were published in 20082 with an update which can be found in box 1. The European Association of Allergy and Clinical Immunology (EAACI) also published an international consensus of drug allergy in February 2014.3 Both of these look at the management of drug allergy within the secondary-care and tertiary-care setting, including details on specialist investigations, in contrast to the NICE guideline, which is aimed at all health professionals who review and manage children including in primary care. Differences between these guidelines are demonstrated in table 1.View this table:Table 1 Comparison of guidelinesBox 1 ### Resources
当任何患者使用一种药物时,它都有可能引起一种有害的、意想不到的反应,即“药物不良反应”(ADR)。药物过敏被定义为具有特定临床特征与免疫机制相容的不良反应,在再次接触该药物后再次发生。有时,如果不需要进一步的调查,仅从临床病史来判断药物反应是否过敏可能是一个挑战。2014年9月,国家健康与护理卓越研究所(NICE)发布了一份题为“药物过敏:成人、儿童和年轻人药物过敏的诊断和管理”的指南这是由于对疑似药物过敏的人提供的护理存在差异,并优化有关药物过敏的诊断、记录和交流的最佳实践建议。我们在这里的重点是针对儿童和年轻人的建议。英国过敏和临床免疫学学会(BSACI)药物过敏管理指南于2008年出版,其更新可在方框1中找到。欧洲过敏和临床免疫学协会(EAACI)也在2014年2月发表了一份关于药物过敏的国际共识。与NICE指南不同,这两份指南都着眼于二级和三级医疗机构的药物过敏管理,包括专家调查的细节,而NICE指南针对的是所有审查和管理儿童的卫生专业人员,包括初级医疗机构。表1展示了这些准则之间的差异。查看该表:表1指导方针的比较

How to use faecal calprotectin in management of paediatric inflammatory bowel disease 如何使用粪钙保护蛋白治疗儿童炎症性肠病
Pub Date : 2016-02-04 DOI: 10.1136/archdischild-2014-307941

Faecal calprotectin (FC) is a neutrophil-derived protein released in stool in response to mucosal inflammation. It is a simple, cheap and non-invasive test with high sensitivity and moderate specificity, which can be useful in the diagnosis and monitoring of inflammatory bowel disease (IBD). FC levels correlate well with bowel inflammation (both macroscopic and histological activity) and are not influenced by disease location or type of IBD. Despite the shortcoming with regards to specificity, it is the high sensitivity of FC that makes it a valuable screening tool in the diagnosis of IBD. It is especially effective in identifying children with low probability of IBD who would not benefit from further investigations. The cut-off value selected has a significant impact on the diagnostic accuracy of the test, influencing its sensitivity and specificity, and must be interpreted judiciously. Its role in disease monitoring is as an add-on test to Paediatric Ulcerative Colitis Activity Index and Paediatric Crohn's Disease Activity Index scores and can be used to differentiate disease relapse from functional symptoms. High levels of FC are also seen in a number of other conditions, such as gastrointestinal infections and coeliac disease. It is recommended that infective causes affecting the gut must be excluded first, before FC is measured.
粪钙保护蛋白(FC)是一种中性粒细胞衍生的蛋白,在粘膜炎症反应时在粪便中释放。它是一种简单、廉价、无创的检测方法,具有高灵敏度和中等特异性,可用于炎症性肠病(IBD)的诊断和监测。FC水平与肠道炎症(宏观和组织学活动)密切相关,不受疾病部位或IBD类型的影响。尽管在特异性方面存在不足,但正是FC的高灵敏度使其成为诊断IBD的有价值的筛查工具。它在识别那些不可能从进一步调查中获益的低概率IBD儿童方面特别有效。截断值的选择对检测的诊断准确性有显著影响,影响其敏感性和特异性,必须审慎解释。它在疾病监测中的作用是作为儿科溃疡性结肠炎活动指数和儿科克罗恩病活动指数评分的附加测试,可用于区分疾病复发和功能性症状。高水平的FC也见于许多其他疾病,如胃肠道感染和乳糜泻。建议在测量FC之前,必须首先排除影响肠道的感染原因。

Medically unexplained symptoms are common and not always easy to manage. A wide range of symptoms may be presented and anxiety in the child, family and paediatrician about the possibility of a missed serious organic diagnosis may hamper effective management. Evidence-based approaches to a number of different presenting problems share a number of components. A model for assessment and management based on clinical experience and this evidence base is described.

How to interpret malaria tests 如何解读疟疾检测结果
Pub Date : 2016-02-02 DOI: 10.1136/archdischild-2015-309048
E. Dyer, T. Waterfield, M. Eisenhut
There are over 300 new cases of imported paediatric malaria in the UK each year and this has been increasing over the last 20 years. Malaria in children is particularly difficult to diagnose because the initial presenting features are subtler than in adults and do not display the classical presenting features. However, they are also more likely to deteriorate rapidly and to develop severe malaria. The ‘gold standard’ for ruling out the diagnosis of malaria if clinically suspected is three negative thin and thick blood films, which require serial phlebotomy and the availability of trained technicians. There are now a range of other tests, including rapid diagnostic tests and PCR, as well as clinical features that make the diagnosis more or less likely. We explore the different tests available and whether these might replace the three negative blood films currently needed. We also look at whether we are able to use clinical features to aid the tests used for a diagnosis of imported malaria.
在英国,每年有超过300例新的输入性儿科疟疾病例,并且在过去20年中一直在增加。儿童疟疾尤其难以诊断,因为其最初的表现特征比成人更为微妙,没有典型的表现特征。然而,它们也更有可能迅速恶化并发展成严重的疟疾。如果临床怀疑是疟疾,排除疟疾诊断的“金标准”是三张阴性的薄血膜和厚血膜,这需要连续的静脉切开术和训练有素的技术人员。现在有一系列其他测试,包括快速诊断测试和PCR,以及使诊断或多或少可能的临床特征。我们探讨了不同的可用测试,以及这些测试是否可以取代目前需要的三种阴性血膜。我们还研究我们是否能够利用临床特征来辅助用于诊断输入性疟疾的检测。

A previously well 10-year-old girl presented with 3 months of L5-S2 back pain. This had started insidiously while in Sudan and woke her nightly. She reported 5 days of constipation and urinary frequency but no neurological symptoms, fevers or weight loss. Her body mass index was normal and she was premenarchal, although had signs of thelarche.Cardiovascular and respiratory examinations were normal. Routine observations were unremarkable. She reported L5-S2 pain upon lumbar extension (not present on palpation). No neurological signs were elicited. Abdominal examination revealed suprapubic fullness, clinically thought to represent constipation, with no organomegaly.What differentials should be considered? What are the red flag symptoms to elicit?Back pain affects 17%–26% of adolescents yet specific diagnoses are reached in only half of the cases.1 Significant pathologies should be carefully considered …
先前健康的10岁女孩表现为3个月的L5-S2背部疼痛。这是在苏丹的时候开始的,她每晚都被吵醒。她报告了5天的便秘和尿频,但没有神经系统症状、发烧或体重减轻。她的身体质量指数正常,虽然有更年期的迹象,但她处于月经前。心血管和呼吸检查正常。常规观察结果并不显著。她报告腰伸时L5-S2疼痛(触诊未见)。未出现神经学症状。腹部检查显示耻骨上充盈,临床认为代表便秘,没有器官肿大。应该考虑哪些差异?哪些是需要引起的危险症状?17%-26%的青少年患有背痛,但只有一半的病例得到了明确的诊断重要的病理应该仔细考虑……

A 2-year-old girl presented to the local emergency department with 4 days of vomiting, poor oral intake and fever. ‘Noisy’ breathing and cough were noted by her parents in the preceding 12 h. She was initially given oral antibiotics for tonsillitis before developing audible stridor. Oral and nebulised steroids were given for presumed croup, and she was transferred to the nearby paediatric emergency department for further management. Intravenous access was established prior to transfer.On paediatric assessment, she appeared pale and sitting in a tripod position with her neck in extension. Soft inspiratory stridor was present with a loud, wet barking cough. Oxygen saturations were maintained with wafting oxygen but desaturated when distressed. She was tachycardic though capillary refill was normal. Intravenous ceftriaxone was administered to cover for bacterial tracheitis, and although she was maintaining her own airway, …
一名2岁女童因呕吐4天、口腔摄入不良和发烧到当地急诊科就诊。在之前的12小时里,她的父母注意到她有“嘈杂”的呼吸和咳嗽。在出现可听到的哮鸣之前,她最初接受了扁桃体炎的口服抗生素治疗。假定组给予口服和雾化类固醇,她被转移到附近的儿科急诊科进行进一步治疗。转移前已建立静脉通路。在儿科评估中,她面色苍白,以三脚架的姿势坐着,颈部伸展。柔和的吸气性喘鸣伴大声、潮湿的吠叫性咳嗽。氧饱和度通过浮氧维持,但在遇险时降低。她心动过速,但毛细血管充盈正常。静脉注射头孢曲松来治疗细菌性气管炎,尽管她还能维持自己的呼吸道…

Public and patient involvement in paediatric research 公众和患者参与儿科研究

Public and patient involvement (PPI) in health research is a dynamic partnership between patients and/or members of the public and researchers. Involvement is distinct from being subjects of research (participation) as patients contribute to the research process as advisors and sometimes co-researchers. In practice, this may mean involvement in prioritising and developing research ideas, contributing to study design, carrying out the research and research dissemination.1 It should be emphasised that involvement is carried out ‘with’ or ‘by’ members of the public rather than ‘to’, ‘about’ or ‘for’ them.2PPI offers researchers valuable and unique insight into the particular condition being investigated to make research more relevant to patients. PPI is needed to improve the quality of research and increase accountability. It is also reported to have benefits of increased recruitment and retention of study participants.3 The reasons for this are varied. The research questions are more likely to be aligned with outcomes valued by patients. Recruitment materials designed with the public will be written more suitably and with greater relevance. Importantly, the public bring important insight into how burdensome study requirements are to everyday life. Additionally, the idea of PPI is itself appealing, which increases willingness to participate in research.For today's researchers, active PPI has further relevance as funding bodies frequently require evidence of PPI in the development of a research proposal and ask how patients and the public might be involved in the conduct of the research. For patients, it is ethical for them to have a voice in research that may have an impact on their health.Dame Sally Davies, chief medical officer for England, advocates PPI as the rule rather than the exception:No matter how complicated the research, or how brilliant the researcher, patients and the public always offer unique, invaluable insights. …
公众和患者参与卫生研究是患者和/或公众成员与研究人员之间的一种动态伙伴关系。参与不同于作为研究的主体(参与),因为患者以顾问的身份参与研究过程,有时也参与研究。在实践中,这可能意味着参与研究思路的优先排序和发展,为研究设计做出贡献,开展研究和传播研究应该强调的是,公众的参与是“与”或“由”公众参与,而不是“向”、“关于”或“为”他们参与。2PPI为研究人员提供了宝贵而独特的见解,使研究与患者更相关。提高研究质量和加强问责制需要PPI。据报道,它也有增加招募和保留研究参与者的好处造成这种情况的原因是多方面的。研究问题更有可能与患者所看重的结果相一致。为公众设计的招聘材料会写得更合适,更有针对性。重要的是,公众对学习要求给日常生活带来的负担有了重要的认识。此外,PPI的想法本身就很吸引人,这增加了参与研究的意愿。对于今天的研究人员来说,活性PPI具有进一步的相关性,因为资助机构在制定研究计划时经常需要PPI的证据,并询问患者和公众如何参与研究的实施。对病人来说,在可能影响他们健康的研究中发表意见是合乎道德的。英国首席医疗官Dame Sally Davies提倡将PPI作为常规而不是例外:无论研究多么复杂,或者研究人员多么杰出,患者和公众总是提供独特的、宝贵的见解。…
