Fifteen-minute consultation: the child with pica

Pica is defined as the persistent ingestion of non-nutritive substances for more than 1 month at an age at which this behaviour is deemed inappropriate. It occurs most commonly in children, in patients with learning disabilities and in pregnancy. The aetiology of pica is poorly understood and is probably multifactorial. Clinical assessment can be difficult. History and examination should be tailored to address potential complications of the substance being ingested. Complications can be life threatening. Pica often self-remits in younger children. In those with learning disabilities, however, pica may persist into adulthood. Management strategies should involve a multidisciplinary approach, and interventions are primarily behavioural in nature. There is limited evidence to support pharmacological interventions in the management of children with pica.

Clinician’s gaze behaviour in simulated paediatric emergencies

Aim Differences in the gaze behaviour of experts and novices are described in aviation and surgery. This study sought to describe the gaze behaviour of clinicians from different training backgrounds during a simulated paediatric emergency. Methods Clinicians from four clinical areas undertook a simulated emergency. Participants wore SMI (SensoMotoric Instruments) eye tracking glasses. We measured the fixation count and dwell time on predefined areas of interest and the time taken to key clinical interventions. Results Paediatric intensive care unit (PICU) consultants performed best and focused longer on the chest and airway. Paediatric consultants and trainees spent longer looking at the defibrillator and algorithm (51 180 ms and 50 551 ms, respectively) than the PICU and paediatric emergency medicine consultants. Conclusions This study is the first to describe differences in the gaze behaviour between experts and novices in a resuscitation. They mirror those described in aviation and surgery. Further research is needed to evaluate the potential use of eye tracking as an educational tool.

Calibration of confidence and assessed clinical skills competence in undergraduate paediatric OSCE scenarios: a mixed methods study

BackgroundThe relationship between confidence and competence in clinical skills development is complex but important. This study aims to determine undergraduate paediatric student confidence in performing three common paediatric clinical skills framed as Objective Structured Clinical Examination (OSCE) scenarios and to compare this with subsequent assessed performance. The study also aims to explore possible barriers to successful paediatric skills completion.MethodsA mixed-methods study was conducted on medical students. Cross-sectional questionnaire data relating to confidence in performing a number of paediatric skills were compared with assessed paediatric skills competency. Focus groups were carried out to identify themes in paediatric skills completion to triangulate this data.ResultsEighty-five medical students participated in the study. Students had high levels of pre-test confidence in their ability to perform paediatrics skills. However agreement between pre-test confidence and subsequent task performance was poor and students had significantly greater belief in their skills ability than was subsequently demonstrated. Focus groups identified paediatric skills complexity, conflicting teaching and having limited supervised skills opportunities and as being possible contributory factors to this discrepancy.ConclusionsStudent paediatric skills confidence is not matched by performance. The reasons for this are diverse but mostly modifiable. A major factor is the lack of supervised skills experience with appropriate feedback to support students in learning to calibrate their confidence against their competence. A number of recommendations are made including the introduction of formative assessment opportunities.

How to use… a blood film

The diagnostic relevance of the blood film cannot be underestimated in the assessment of children with suspected primary or secondary haematological conditions. The blood film not only serves as a diagnostic tool but also allows for screening, monitoring of disease progression and therapeutic response in children with a variety of haematological conditions. This article outlines the appearance of normal paediatric and neonatal blood films. The technical aspects involved in preparing a blood film are discussed. Consideration is given to the indications for preparing a blood film and some of the limitations of blood films. Finally, attempts are made to highlight the role of the blood film in the diagnosis of some common paediatric and neonatal conditions.

How to use the videofluoroscopy swallow study in paediatric practice

In paediatric practice feeding, eating, drinking and swallowing difficulties are present in up to 1% of children. Dysphagia is any disruption to the swallow sequence that results in compromise to the safety, efficiency or adequacy of nutritional intake. Swallowing difficulties may lead to pharyngeal aspiration, respiratory compromise or poor nutritional intake. It causes sensory and motor dysfunction impacting on a child’s ability to experience normal feeding. Incoordination can result in oral pharyngeal aspiration where fluid or food is misdirected and enters the airway, or choking where food physically blocks the airway The incidence is much higher in some clinical populations, including children with neuromuscular disease, traumatic brain injury and airway malformations. The prevalence of dysphagia and aspiration-related disease is increasing secondary to the better survival of children with highly complex medical and surgical needs. This article aims to outline the indications for performing videofluoroscopy swallow (VFS). This includes the technical aspects of the study, how to interrupt a VFS report and some of the limitations to the study.

G168 An observational study of clinician’s gaze behaviour during simulated paediatric emergencies

Aims Clinicians collect, prioritise and respond to visual cues when making decisions about patient care. This is of particular importance in the resuscitation environment where they are required to absorb and process large volumes of complex visual information in a time critical manner. Eye tracking technology allows for the measurement of an observer’s point of gaze based on where their pupil is focused. Eye tracking technology has been used in aviation and surgery to describe differences in the gaze behaviour between experts and novices. The aim of this study was to describe the gaze behaviour of clinicians from different training backgrounds during a simulated paediatric emergency. Methods Twenty-seven clinicians from different clinical areas within a tertiary children’s hospital undertook a standardised, six minute, high fidelity simulated paediatric emergency. Participants wore SMI Eye Tracking Glasses. We measured the number of times participants looked at predefined key areas (fixation count) and the duration of time spent looking at each of these areas (dwell time). The time taken to key clinical interventions was also recorded. Results Participants from all groups looked more frequently and for longer at the patient (chest and airway) than any of the other key areas of interests. Paediatric Intensive Care Unit (PICU) consultants focused longer on the chest and airway than any other groups. The gaze behaviour of paediatric consultants and trainees was similar. Both groups spent longer looking at the defibrillator and algorithm (51,180 ms and 50,551 ms respectively) than the PICU consultants and consultants in paediatric emergency medicine (19,804 ms and 28,095 ms respectively). The PICU consultants were quickest to perform key clinical interventions. Conclusions This study is the first to describe differences in the gaze behaviour between clinicians from different backgrounds during a simulated paediatric emergency. Differences observed between experts and novices are similar to those described in aviation and surgery. Further research is needed to evaluate the potential use as an educational tool in the resuscitation setting.

Is vitamin D useful in the treatment of growing pains

A 6-year-old girl attends your general paediatric outpatient clinic. She describes intermittent pain in both legs over a period of 4 months. The pain is worse at night. She is otherwise well and clinical examination is normal. Blood tests sent by her general practitioner are normal except for a vitamin D level of 35 nmol/L. You make a diagnosis of growing pains and wonder whether there is any evidence to support giving vitamin D in the management of growing pains. Is treatment with vitamin D an effective management option in a 6-year-old girl with growing pains? We searched PubMed and Medline (1946–present) using the key words: ‘Vitamin D’ AND ‘child* OR adoles*’ AND ‘growing pains’. The search was performed in June 2017. The results were filtered to include only English articles. The PubMed search yielded 14 results. Following review of the titles and abstracts five articles were identified for full-text review. The Medline search yielded five results. These were the same five articles identified for full-text review in our PubMed search. After a detailed appraisal of these five articles, we selected four papers which we felt adequately addressed the clinical question. No further …
