Abstract
Acute lower respiratory infection is the leading cause of child death in developing countries. Current strategies to reduce this problem include early detection and appropriate treatment. Better diagnostic and therapeutic strategies are still needed in poor countries. Artificial-intelligence chest X-ray scheme has the potential to become a screening tool for lower respiratory infection in child. Artificial-intelligence chest X-ray schemes for children are rare and limited to a single lung disease. We need a powerful system as a diagnostic tool for most common lung diseases in children. To address this, we present a computer-aided diagnostic scheme for the chest X-ray images of several common pulmonary diseases of children, including bronchiolitis/bronchitis, bronchopneumonia/interstitial pneumonitis, lobar pneumonia, and pneumothorax. The study consists of two main approaches: first, we trained a model based on YOLOv3 architecture for cropping the appropriate location of the lung field automatically. Second, we compared three different methods for multi-classification, included the one-versus-one scheme, the one-versus-all scheme and training a classifier model based on convolutional neural network. Our model demonstrated a good distinguishing ability for these common lung problems in children. Among the three methods, the one-versus-one scheme has the best performance. We could detect whether a chest X-ray image is abnormal with 92.47% accuracy and bronchiolitis/bronchitis, bronchopneumonia, lobar pneumonia, pneumothorax, or normal with 71.94%, 72.19%, 85.42%, 85.71%, and 80.00% accuracy, respectively. In conclusion, we provide a computer-aided diagnostic scheme by deep learning for common pulmonary diseases in children. This scheme is mostly useful as a screening for normal versus most of lower respiratory problems in children. It can also help review the chest X-ray images interpreted by clinicians and may remind possible negligence. This system can be a good diagnostic assistance under limited medical resources.

Randomized controlled trial of asthma risk with paracetamol use in infancy--a feasibility study. Clin Exp Allergy 2015; 45:448-56. [PMID: 25303337 DOI: 10.1111/cea.12433] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2014] [Revised: 09/03/2014] [Accepted: 09/26/2014] [Indexed: 11/29/2022]
Abstract
BACKGROUND There is non-experimental evidence that paracetamol (acetaminophen) use may increase the risk of developing asthma. However, numerous methodological issues need to be resolved before undertaking a randomized controlled trial to investigate this hypothesis. OBJECTIVE To establish the feasibility of a randomized controlled trial of liberal paracetamol as usually given by parents/guardians vs. a comparator (restricted paracetamol in accordance with WHO guidelines, ibuprofen or placebo), and childhood asthma risk. METHODS Questionnaires were completed by parents/guardians of infants admitted to Wellington Hospital with bronchiolitis to assess views about comparator treatments. Subsequently, infants of parents/guardians who provided informed consent were randomized to restricted or liberal paracetamol use for 3 months with paracetamol use recorded. RESULTS Of 120 eligible participants, 72 (60%) parents/guardians completed the questionnaire. Ibuprofen, restricted paracetamol and placebo were acceptable to 42 (58%), 29 (40%) and 9 (12%) parents/guardians, respectively. 36 (30%) infants were randomized to restricted or liberal paracetamol. Paracetamol use was greater for the liberal vs. restricted group for reported [Hodges-Lehmann estimator of difference 0.94 mg/kg/day (95% CI 0.2-3.52), P = 0.02] and measured use [Hodges-Lehmann estimator of difference 2.11 mg/kg/day (95% CI 0.9-4.18), P = 0.004]. The median reported and measured use of paracetamol was 2.0-fold and 3.5-fold greater in the liberal vs. restricted group. CONCLUSIONS AND CLINICAL RELEVANCE Although separation in paracetamol dosing is likely to be achieved with a liberal vs. restricted paracetamol regime, ibuprofen is the preferred comparator treatment in the proposed RCT of paracetamol use and risk of asthma in childhood.

Abstract
BACKGROUND Acute bronchiolitis is the most common cause of hospitalisation in infancy. Supportive care and oxygen are the cornerstones of management. A Cochrane review concluded that the use of nebulised 3% hypertonic saline (HS) may significantly reduce the duration of hospitalisation. OBJECTIVE To test the hypothesis that HS reduces the time to when infants were assessed as being fit for discharge, defined as in air with saturations of > 92% for 6 hours, by 25%. DESIGN Parallel-group, pragmatic randomised controlled trial, cost-utility analysis and systematic review. SETTING Ten UK hospitals. PARTICIPANTS Infants with acute bronchiolitis requiring oxygen therapy were allocated within 4 hours of admission. INTERVENTIONS Supportive care with oxygen as required, minimal handling and fluid administration as appropriate to the severity of the disease, 3% nebulised HS every ± 6 hours. MAIN OUTCOME MEASURES The trial primary outcome was time until the infant met objective discharge criteria. Secondary end points included time to discharge and adverse events. The costs analysed related to length of stay (LoS), readmissions, nebulised saline and other NHS resource use. Quality-adjusted life-years (QALYs) were estimated using an existing utility decrement derived for hospitalisation in children, together with the time spent in hospital in the trial. DATA SOURCES We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials and other databases from inception or from 2010 onwards, searched ClinicalTrials.gov and other registries and hand-searched Chest, Paediatrics and Journal of Paediatrics to January 2015. REVIEW METHODS We included randomised/quasi-randomised trials which compared HS versus saline (± adjunct treatment) or no treatment. We used a fixed-effects model to combine mean differences for LoS and assessed statistical heterogeneity using the I (2) statistic. RESULTS The trial randomised 158 infants to HS (n = 141 analysed) and 159 to standard care (n = 149 analysed). There was no difference between the two arms in the time to being declared fit for discharge [median 76.6 vs. 75.9 hours, hazard ratio (HR) 0.95, 95% confidence interval (CI) 0.75 to 1.20] or to actual discharge (median 88.5 vs. 88.7 hours, HR 0.97, 95% CI 0.76 to 1.23). There was no difference in adverse events. One infant developed bradycardia with desaturation associated with HS. Mean hospital costs were £2595 and £2727 for the control and intervention groups, respectively (p = 0.657). Incremental QALYs were 0.0000175 (p = 0.757). An incremental cost-effectiveness ratio of £7.6M per QALY gained was not appreciably altered by sensitivity analyses. The systematic review comprised 15 trials (n = 1922) including our own. HS reduced the mean LoS by -0.36 days (95% CI -0.50 to -0.22 days). High levels of heterogeneity (I (2) = 78%) indicate that the result should be treated cautiously. CONCLUSIONS In this trial, HS had no clinical benefit on LoS or readiness for discharge and was not a cost-effective treatment for acute bronchiolitis. Claims that HS achieves small reductions in LoS must be treated with scepticism. FUTURE WORK Well-powered randomised controlled trials of high-flow oxygen are needed.

Effect of inhaled hypertonic saline on hospital admission rate in children with viral bronchiolitis: a randomized trial. CAN J EMERG MED 2015; 12:477-84.

Abstract
ABSTRACT
Objective:
We sought to determine whether inhaled 3% hypertonic saline (HS) reduces admission to hospital in ambulatory children with moderately severe viral bronchiolitis. Secondary objectives compared changes in respiratory scores before and after treatment and assessed the need for unscheduled medical intervention within 7 days.
Methods:
Children under the age of 2 years presenting with moderately severe viral bronchiolitis to the emergency department of 4 general hospitals from November 2008 to March 2009 were randomly assigned to receive 3 consecutive 4-mL doses of nebulized 3% HS (treatment group) or 0.9% normal saline (NS; control group) in a double blind fashion, each coadministered with 1 mg salbutamol. Outcome measures included the difference in hospital admission rate and changes in respiratory distress scores.
Results:
A total of 81 children (mean age 8.9 mo, range 0.7–22 mo) were assessed over 88 visits on an intention-to-treat basis. No statistically significant differences were found between treatment groups. Children in the HS group had a nonsignificant trend toward greater improvement compared with NS controls with a same-day admission rate of 18% (95% confidence interval [CI] 9%–32%) versus 27% (95% CI 16%–42%), respectively. Respiratory Assessment Change Scores (RACS) favoured the HS group over NS controls (mean RACS 4.7 [95% CI 3.6–5.8] v. 3.7 [95% CI 2.5–4.9], respectively), although the CIs overlap and these differences were not statistically significant.
Conclusion:
The short-term use of nebulized 3% HS did not result in any statistically significant benefits, although a nonsignificant trend toward a decrease in admission rate and improvement in respiratory distress was found. A larger study would be required to determine whether these trends arise from a clinically relevant treatment effect.

Abstract
BACKGROUND Bronchiolitis is one of the most common respiratory problems in the first year of life. The sputum of infants with bronchiolitis has increased deoxyribonucleic acid (DNA) content, leading to mucous plugging and airway obstruction. Recombinant human deoxyribonuclease (rhDNase), an enzyme that digests extracellular DNA, might aid the clearance of mucus and relieve peripheral airway obstruction. OBJECTIVES To determine the effect of nebulised rhDNase on the severity and duration of viral bronchiolitis in children younger than 24 months of age in the hospital setting. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) 2012, Issue 7 which includes the Acute Respiratory Infections Group's Specialised Register, MEDLINE (1966 to July Week 4, 2012), EMBASE (1974 to August 2012) and LILACS (1982 to August 2012). SELECTION CRITERIA Randomised controlled trials (RCTs) using nebulised rhDNase alone or with concomitant therapy in children younger than 24 months of age hospitalised with acute bronchiolitis. DATA COLLECTION AND ANALYSIS Two review authors independently performed literature searches, assessed trial quality and extracted data. We obtained unpublished data from trial authors. We used Review Manager 5.1 to pool treatment effects expressed as the mean difference (MD) or standardised mean difference (SMD) with 95% confidence intervals (CI). MAIN RESULTS Three RCTs (333 participants) were identified, two of which were multicentre trials comprising only participants positive for respiratory syncytial virus (RSV). The other trial enrolled participants clinically diagnosed with bronchiolitis from a hospital in Italy. All studies used 2.5 mL (1 mg/mL) of nebulised rhDNase compared with placebo either as a daily or a twice daily dose. Adjunctive therapy included nebulised salbutamol, steroids, supplemental oxygen, intravenous fluids or tube feeding, nasal washing, nasal decongestants and antibiotics.Overall, nebulised rhDNase showed no benefit in clinically meaningful outcomes. Meta-analysis favoured the control group with a shorter duration of hospital stay (MD 0.50; 95% CI 0.10 to 0.90, P = 0.01) and better clinical score improvement (SMD -0.24; 95% CI -0.50 to 0.01, P = 0.06). The largest trial showed no difference in supplemental oxygen use or intensive care unit (ICU) admission.In one RCT, four out of 11 patients in the treatment group had atelectasis. Two of these patients showed distinctive clinical improvement after nebulised rhDNase.There was no significant difference in adverse events. These included temporary desaturation, temporary coughing, increased coughing, facial rash, hoarseness, dyspnoea and bad taste, reported in a total of 11 patients from both treatment groups. AUTHORS' CONCLUSIONS The results based on the three included studies in this review did not support the use of nebulised rhDNase in children under 24 months of age hospitalised with acute bronchiolitis. In these patients, treatment did not shorten the length of hospitalisation or improve clinical outcomes. It might have a role in severe bronchiolitis complicated by atelectasis, but further clinical studies would need to be performed.

Randomized placebo-controlled trial on azithromycin to reduce the morbidity of bronchiolitis in Indigenous Australian infants: rationale and protocol. Trials 2011; 12:94.

Abstract
BACKGROUND Acute lower respiratory infections are the commonest cause of morbidity and potentially preventable mortality in Indigenous infants. Infancy is also a critical time for post-natal lung growth and development. Severe or repeated lower airway injury in very young children likely increases the likelihood of chronic pulmonary disorders later in life. Globally, bronchiolitis is the most common form of acute lower respiratory infections during infancy. Compared with non-Indigenous Australian infants, Indigenous infants have greater bacterial density in their upper airways and more severe bronchiolitis episodes. Our study tests the hypothesis that the anti-microbial and anti-inflammatory properties of azithromycin, improve the clinical outcomes of Indigenous Australian infants hospitalised with bronchiolitis. METHODS We are conducting a dual centre, randomised, double-blind, placebo-controlled, parallel group trial in northern Australia. Indigenous infants (aged ≤ 24-months, expected number = 200) admitted to one of two regional hospitals (Darwin, Northern Territory and Townsville, Queensland) with a clinical diagnosis of bronchiolitis and fulfilling inclusion criteria are randomised (allocation concealed) to either azithromycin (30 mg/kg/dose) or placebo administered once weekly for three doses. Clinical data are recorded twice daily and nasopharyngeal swab are collected at enrollment and at the time of discharge from hospital. Primary outcomes are 'length of oxygen requirement' and 'duration of stay,' the latter based upon being judged as 'ready for respiratory discharge'. The main secondary outcome is readmission for a respiratory illness within 6-months of leaving hospital. Descriptive virological and bacteriological (including development of antibiotic resistance) data from nasopharyngeal samples will also be reported. DISCUSSION Two published studies, both involving different patient populations and settings, as well as different macrolide antibiotics and treatment duration, have produced conflicting results. Our randomised, placebo-controlled trial of azithromycin in Indigenous infants hospitalised with bronchiolitis is designed to determine whether it can reduce short-term (and potentially long-term) morbidity from respiratory illness in Australian Indigenous infants who are at high risk of developing chronic respiratory illness. If azithromycin is efficacious in reducing the morbidly of Indigenous infants hospitalised with bronchiolitis, the intervention would lead to improved short term (and possibly long term) health benefits.

Abstract
La bronchiolite è un’infezione virale stagionale delle vie respiratorie basse del lattante. Il suo agente causale principale è il virus respiratorio sinciziale. La comparsa di un distress respiratorio è legata all’intensità della risposta infiammatoria delle vie aeree. Benché si tratti di una malattia frequente, le cause della suscettibilità dei lattanti a questa infezione non sono conosciute. La diagnosi è clinica. Il trattamento è sintomatico in assenza di misure specifiche. I rapporti a medio e a lungo termine di un primo episodio di bronchiolite con le recidive e con l’asma non sono spiegati. Essi potrebbero dipendere dalla natura del virus in causa al momento del primo episodio e da fattori genetici individuali.

Abstract
CONTEXT The term small airways disease encompasses a generally poorly understood group of lung diseases that may arise primarily within the small airways or secondarily from diseases primarily affecting the bronchi or lung parenchyma. Their histology may be confusing; however, because treatments and prognoses vary, correct pathologic diagnosis is important. OBJECTIVE To present a nonexhaustive review of the pathology of primary and secondary small airways diseases, including small airways disease related to tobacco; to various other exposures, including mineral dusts; to diseases involving other areas of the lung with secondary bronchiolar involvement; and to recently described bronchiolitic disorders. DATA SOURCES Current literature is reviewed. CONCLUSIONS Small airways diseases include a wide variety of diseases of which the pathologist must consider. Uncommon conditions such as diffuse idiopathic neuroendocrine cell hyperplasia and diffuse panbronchiolitis may show relatively specific diagnostic features histologically; however, most small airways diseases exhibit nonspecific histologic features. Conditions not considered primary pulmonary diseases, such as collagen vascular diseases, bone marrow transplantation, and inflammatory bowel disease, must also be considered in patients with small airways changes histologically. Clinical and radiologic correlation is important for obtaining the best possible diagnosis.

Abstract
Acute lower respiratory infections (ALRI) are the major cause of morbidity and mortality in young children worldwide. ALRIs are important indicators of the health disparities that persist between Indigenous and non-Indigenous children in developed countries. Bronchiolitis and pneumonia account for the majority of the ALRI burden. The epidemiology, diagnosis, and management of these diseases in Indigenous children are discussed. In comparison with non-Indigenous children in developing countries they have higher rates of disease, more complications, and their management is influenced by several unique factors including the epidemiology of disease and, in some remote regions, constraints on hospital referral and access to highly trained staff. The prevention of repeat infections and the early detection and management of chronic lung disease is critical to the long-term respiratory and overall health of these children.
