Evaluating the child with recurrent lower respiratory tract infections

Low Prevalence of Severe Underlying Pathology in Children With Recurrent Respiratory Tract Infections

No underlying pathology could be detected in 64% of 208 children presenting with recurrent respiratory tract infections in general pediatric practice. Asthma/preschool wheezing and adenoid hypertrophy were commonly diagnosed. None of the children had a severe primary immunodeficiency or severe pulmonary illness such as cystic fibrosis. Our findings can guide pediatricians in their diagnostic approach of children with respiratory tract infections.

ACR Appropriateness Criteria® Pneumonia in the Immunocompetent Child

Pneumonia is one of the most common acute infections and the single greatest infectious cause of death in children worldwide. In uncomplicated, community-acquired pneumonia in immunocompetent patients, the diagnosis is clinical and imaging has no role. The first role of imaging is to identify complications associated with pneumonia such as pleural effusion, pulmonary abscess, and bronchopleural fistula. Radiographs are recommended for screening for these complications and ultrasound and CT are recommended for confirmation. The second role of imaging is to identify underlying anatomic conditions that may predispose patients to recurrent pneumonia. CT with intravenously administered contrast is recommended for this evaluation. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Reliability and Construct Validity of the Penetration-Aspiration Scale for Quantifying Pediatric Outcomes after Interarytenoid Augmentation

OBJECTIVE

To assess the reliability and construct validity of the Penetration-Aspiration Scale in children.

STUDY DESIGN

This was a retrospective cohort study of pre- and postoperative video modified barium swallow studies from children who underwent interarytenoid injection augmentation for unexplained persistent pharyngeal dysphagia. Two pediatric speech and language pathologists reviewed each study twice in a blinded and randomized fashion.

SETTING

Tertiary academic pediatric hospital.

SUBJECTS AND METHODS

Thirty children were identified with adequate pre- and postoperative modified barium swallow studies within 4 weeks of intervention. Children were separated into clinical outcome groups based on ability to advance to thinner diet consistencies postoperatively. Construct validity was assessed with a mixed linear model to test the hypothesis that only the clinically improved group would receive better Penetration-Aspiration Scale scores after surgery. Reliability was assessed by calculating chance-corrected agreement between raters (interrater) and raters' repeat evaluations (intrarater).

RESULTS

Inter- and intrarater reliabilities (Cohen's κ) were both excellent. Results of the mixed model revealed a significant interaction between outcome group and pre- and postoperative time interval. As hypothesized, this involved a significant improvement in Penetration-Aspiration Scale score only in the improved group.

CONCLUSIONS

These findings suggest that the Penetration-Aspiration Scale is a reliable and valid measure of clinical response to interarytenoid injection augmentation in children.

Recurrent Pneumonia in Children: A Reasoned Diagnostic Approach and a Single Centre Experience

Recurrent pneumonia (RP), i.e., at least two episodes of pneumonia in one year or three episodes ever with intercritical radiographic clearing of densities, occurs in 7.7%–9% of children with community-acquired pneumonia. In RP, the challenge is to discriminate between children with self-limiting or minor problems, that do not require a diagnostic work-up, and those with an underlying disease. The aim of the current review is to discuss a reasoned diagnostic approach to RP in childhood. Particular emphasis has been placed on which children should undergo a diagnostic work-up and which tests should be performed. A pediatric case series is also presented, in order to document a single centre experience of RP. A management algorithm for the approach to children with RP, based on the evidence from a literature review, is proposed. Like all algorithms, it is not meant to replace clinical judgment, but it should drive physicians to adopt a systematic approach to pediatric RP and provide a useful guide to the clinician.

Both pharyngeal and esophageal phases of swallowing are associated with recurrent pneumonia in pediatric patients

INTRODUCTION

One of the underlying causes of recurrent pneumonia in children is swallowing dysfunction, with aspiration syndrome. Swallowing dysfunction should be considered not only a problem of the oropharyngeal phase but also a problem of the esophageal phase.

OBJECTIVES

This study aimed to determine the relationship between findings from a swallowing study and a history of recurrent pneumonia in pediatric patients.

METHODS

A videofluroscopic swallowing study of 274 pediatric patients who had swallowing dysfunction was conducted. Information on a history of recurrent pneumonia during a 1-year period was obtained from hospital files.

RESULTS

The median age of the participants was 33 months (min =10, max = 180), of whom 51.8% were females. In the study, 83.2% of the patients had cerebral palsy, 7.7% had syndromic symptoms, 3.6% had muscular dystrophy, and 5.5% were classified as "other." During the 1-year period, 67.9% of the participants had a history of recurrent pneumonia history. Furthermore, 66.4% had oral dysfunction, 32.5% had laryngeal penetration, 46.4% had aspiration, 45.3% had abnormal esophageal body function, and 35.8% had reflux symptoms. There was no correlation between oral dysfunction and recurrent pneumonia (P = .902), but there was a positive correlation between recurrent pneumonia and laryngeal penetration (P < .001, r = .26), aspiration (P < .001, r =.49), abnormal esophageal body function (P = .002, r = .18), and reflux (P < .001, r = .22).

CONCLUSION

Both pharyngeal swallowing disorders, such as penetration and aspiration, and esophageal disorders and reflux may result in recurrent pneumonia in pediatric patients. Thus, all phases of deglutition should be considered and followed up during swallowing evaluation.

Beyond the “Choosing wisely”: a possible attempt

Since the fundamental principles of the medical profession were clearly defined in a physician charter in 2002, special considerations have been expressed about the adequate distribution of health care resources taking in account the individual patient needs to optimize the health care service. The correct application of procedures represents a key point in order to reach the appropriateness of care, that means to avoid unnecessary or inappropriate procedures as well as the underutilization of the necessary procedures. In this context, the Choosing wisely campaign have been widely used and disclosed and even the Italian Society of Pediatric Allergology and Immunology - SIAIP has been working to make recommendations in order to ensure the appropriateness of care in the field of allergy and optimize the use of health care resources.

Recurrent/Persistent Pneumonia among Children in Upper Egypt

OBJECTIVES

Recurrent/persistent pneumonia in children continues to be a major challenge for the pediatricians. The aim of our study was to establish the prevalence and underlying causes of recurrent/persistent pneumonia in children in Upper Egypt.

SETTINGS

Assiut University Children Hospital, Assiut, Egypt.

PATIENTS AND METHODS

Patients, admitted for pneumonia to the hospital during 2 years, were investigated with microbiological, biochemical, immunological and radiological tests in order to establish the prevalence of recurrent/persistent pneumonia and to find out its underlying causes.

RESULTS

113 out of 1228 patients (9.2%) met the diagnosis of recurrent/persistent pneumonia. Identified causes were; aspiration syndrome (17.7%), pulmonary TB (14.0%), congenital heart disease (11.5%), bronchial asthma (9.7%), immune deficiency disorders (8.8%) and vitamin D deficiency rickets (7.0%). Other causes included; congenital anomalies of the respiratory tract, interstitial lung diseases, bronchiectasis, and sickle cell anemia. No predisposing factors could be identified in 15% of cases.

CONCLUSION

Approximately 1 out of 10 children with diagnosis of pneumonia in Assiut University Children Hospital had recurrent/persistent pneumonia. The most frequent underlying cause for recurrent/persistent pneumonia was aspiration syndrome, followed by pulmonary TB.
