Conservative Treatment of Parapneumonic Effusion in Children: Experience From a 10-Year Consecutive Case Series.

BACKGROUND: In children with parapneumonic effusion (PPE), it remains unclear when conservative treatment with antibiotics suffixes or when pleural drainage is needed. In this study we evaluate clinical features and outcomes of children with PPE. METHODS: A retrospective, multicentre cohort study at 4 Dutch pediatric departments was performed, including patients 1-18 years treated for PPE between January 2010 and June 2020. RESULTS: One hundred thirty-six patients were included (mean age 8.3 years, SD 4.8). 117 patients (86%) were treated conservatively and 19 (14%) underwent pleural drainage. Patients undergoing pleural drainage had mediastinal shift more frequently compared with conservatively treated patients (58 vs. 3%, difference 55%; 95% CI: 32%-77%). The same accounted for pleural septations/pockets (58 vs. 11%, difference 47%; 95% CI: 24%-70%), pleural thickening (47 vs. 4%, difference 43%; 95% CI: 20%-66%) and effusion size (median 5.9 vs. 2.7 cm; P = 0.032). Conservative management was successful in 27% of patients (4 of 15) with mediastinal shift, 54% of patients (13 of 24) with septations/pockets, 36% of patients (5 of 14) with pleural thickening, and 9% of patients (3 of 32) with effusions >3 cm, all radiological signs generally warranting pleural drainage. In patients treated conservatively, median duration of hospitalization was 5 days (IQR 4-112) compared with 19 days (IQR 15-24) in the drainage group ( P < 0.001), without significant difference in readmission rate (11 vs. 4%, difference 6%; 95% CI: -8%-21%). CONCLUSION: This study suggests that the greater amount of children with PPE could be treated conservatively with antibiotics only, especially in absence of mediastinal shift, pleural septations/pockets, pleural thickening or extensive effusions.

Question 6: What is the use of allergy testing in children with asthma?

Disagreement exists between asthma guidelines on the routine use of allergy testing in the diagnostic work-up of a child with persistent asthma, although the important role of inhalant allergy in the pathophysiology of asthma and allergic rhinitis is undisputed. The usefulness of screening for inhalant allergies in asthma is connected to the efficacy of allergen reduction measures and specific immunotherapy, both of which appear to be more effective in children than in adults. Allergen-specific exposure reduction recommendations are therefore an essential part of childhood asthma management. Such recommendations should be guided by appropriate diagnosis of inhalant allergy, based on a structured allergy history and results of sensitization tests. Specific IgE testing and skin prick testing show comparable results in identifying clinically important sensitizations. Although a therapeutic medication trial can be started pragmatically in children with asthma without diagnosing their inhalant allergy, we recommend making or excluding an accurate diagnosis of inhalant allergy.

Barriers and Facilitators When Implementing Web-Based Disease Monitoring and Management as a Substitution for Regular Outpatient Care in Pediatric Asthma: Qualitative Survey Study.

BACKGROUND: Despite their potential benefits, many electronic health (eHealth) innovations evaluated in major studies fail to integrate into organizational routines, and the implementation of these innovations remains problematic. OBJECTIVE: The purpose of this study was to describe health care professionals' self-identified perceived barriers and facilitators for the implementation of a Web-based portal to monitor asthmatic children as a substitution for routine outpatient care. Also, we assessed patients' (or their parents) satisfaction with this eHealth innovation. METHODS: Between April and November 2015, we recruited 76 health care professionals (from 14 hospitals). During a period of 6 months, participants received 3 questionnaires to identify factors that facilitated or impeded the use of this eHealth innovation. Questionnaires for patients (or parents) were completed after the 6-month virtual asthma clinic (VAC) implementation period. RESULTS: Major perceived barriers included concerns about the lack of structural financial reimbursement for Web-based monitoring, lack of integration of this eHealth innovation with electronic medical records, the burden of Web-based portal use on clinician workload, and altered patient-professional relationship (due to fewer face-to-face contacts). Major perceived facilitators included enthusiastic and active initiators, a positive attitude of professionals toward eHealth, the possibility to tailor care to individual patients ("personalized eHealth"), easily deliverable care according to current guidelines using the VAC, and long-term profit and efficiency. CONCLUSIONS: The implementation of Web-based disease monitoring and management in children is complex and dynamic and is influenced by multiple factors at the levels of the innovation itself, individual professionals, patients, social context, organizational context, and economic and political context. Understanding and defining the barriers and facilitators that influence the context is crucial for the successful implementation and sustainability of eHealth innovations.

Management and outcome of 35 cases with foetal/neonatal alloimmune neutropenia.

AIM: The aim of this study was to provide an overview of foetal/neonatal alloimmune neutropenia (FNAIN), together with advice on the clinical management. METHODS: Neutrophil serology in the Netherlands is centralised at Sanquin Diagnostic Services. We examined FNAIN cases between January 1, 1991, and July 1, 2013, to determine the number of cases diagnosed, the relationship with human neutrophil antigen (HNA) antibody, the clinical presentation and therapeutic interventions. RESULTS: We identified 35 FNAIN cases. The detected HNA antibodies were as follows: anti-HNA-1a (n = 7), anti-HNA-1b (n = 12), anti-HNA-1c (n = 2), anti-HNA-2 (n = 8), anti-HNA-3a (n = 1), anti-HNA-5a (n = 1) and anti-FcγRIIIb (n = 4). No infections were diagnosed in 14 neonates, and the other 21 neonates suffered from omphalitis (n = 6), urinary tract infection (n = 1), candida mucositis (n = 1), fever of unknown origin (n = 6) and sepsis (n = 7, 20%). Parity, gestational age, birthweight, neutrophil counts and antibody specificity were not significantly different for cases with, and without, infections. All the infected children were treated with antibiotics. No children died. CONCLUSION: More than half (21) of the 35 cases of FNAIN presented with infections and most implicated were HNA-1a, HNA-1b and HNA-2. Treatment with antibiotics seemed adequate. A neonatal neutropenia workflow model for use in neonatal intensive care units is presented.

Langerhans cell histiocytosis presenting with complicated pneumonia, a case report.

We describe a 2 ½ year old boy presenting with fever, abdominal pain and splinter haemorrhages of the nails. On further examination there were signs of pneumonia with pleural effusion. This was treated with mini-thoracotomy, drainage and intravenous antibiotics. Further diagnostic workup for underlying causes showed diffuse cystic lung disease, suggestive of Langerhans cell histiocytosis. This was confirmed on pathology specimens, which showed Langerhans cells in lung tissue, nail bed and skin biopsy samples, indicating multisystem Langerhans cell histiocytosis. The patient was treated with Prednisone and Vinblastin according to the LCH-III guidelines. In this case report we give a brief description on cystic lung disease in children, Langerhans cell histiocytosis and associated nail abnormalities.

Pulmonary disease assessment in cystic fibrosis: comparison of CT scoring systems and value of bronchial and arterial dimension measurements.

PURPOSE: To retrospectively compare thin-section computed tomographic (CT) scores obtained with five scoring systems for assessment of pulmonary disease in children with cystic fibrosis and to determine additional value of bronchial and arterial dimension measurements. MATERIALS AND METHODS: Scores obtained with five thin-section CT scoring systems were compared. A score of 0 indicated the absence of abnormalities; a higher score meant that more structural abnormalities were seen. Three observers assigned scores and then reassigned scores after intervals varying from 1-2 weeks to 1-2 months at review of thin-section CT scans obtained in 25 children with cystic fibrosis. Interobserver and intraobserver reliability was calculated with intraclass correlation coefficients. Quantitative measurements of bronchial and arterial dimensions were obtained. Thin-section CT scores were correlated (Spearman correlation) with bronchial and arterial dimensions and with results of pulmonary function tests (PFTs), such as forced expiratory volume in 1 second (FEV(1)). RESULTS: Scores with all five scoring systems were reproducible, with intraclass correlation coefficients of 0.74 and higher (P <.05), and showed significant correlations with FEV(1) (R = -0.73 to -0.69, P <.01). Ratio of bronchial diameter to accompanying pulmonary arterial diameter was correlated with thin-section CT scores but not with FEV(1). Ratio of bronchial wall thickness to accompanying pulmonary arterial diameter was not correlated with thin-section CT scores or PFT results. CONCLUSION: Thin-section CT scores were reproducible and were correlated with PFT results. Measurements of bronchial dimensions were not significantly related to scores or PFT results.
