Pediatric Airway Endoscopy: Recommendations of the Society for Pediatric Pneumology.

For many decades, pediatric bronchoscopy has been an integral part of the diagnosis and treatment of acute and chronic pulmonary diseases in children. Rapid technical advances have continuously influenced the performance of the procedure. Over the years, the application of pediatric bronchoscopy has considerably expanded to a broad range of indications. In this comprehensive and up-to-date guideline, the Special Interest Group of the Society for Pediatric Pneumology reviewed the most recent literature on pediatric bronchoscopy and reached a consensus on a safe technical performance of the procedure.

Balloon Eustachian Tuboplasty (BET) in Children: A Retrospective Multicenter Analysis.

OBJECTIVE: Generation of pilot data for planning of prospective BET-studies for treatment of dilatory Eustachian tube (ET) dysfunction in children. STUDY DESIGN: Retrospective multicenter analysis. SETTING: Nine ENT departments at tertiary care teaching hospitals. PATIENTS: 4-12-year-old children with chronic otitis media with effusion (COME) for more than 3 months or more than 3 episodes of acute otitis media during the last year, having failed standard surgical therapy at least once. INTERVENTION: BET with or without paracentesis, ventilation tube insertion, or tympanoplasty. MAIN OUTCOME MEASURES: Tympanic membrane appearance, tympanometry, and hearing threshold. RESULTS: Two hundred ninety-nine ETs of 167 children were treated. Mean age was 9.1 years (95% confidence interval [95% CI]: 8.7-9.4 yr). In 249 ears (83.3%), COME and/or retraction of the tympanic membrane were the indication for BET. Median hearing threshold was 20 dB HL (95% CI: 0-46 dB). One hundred fifty-five ears (51.8%, 95% CI: 46.1-57.4%) showed a tympanogram type B. Treatment consisted of BET without other interventions ("BET-only") in 70 children, 128 ears. Median length of follow-up for 158 (94.6%) children was 2.6 months (95% CI: 0.3-16.1 mo). After treatment, the tympanic membrane appeared normal in 196 ears (65.6%, 95% CI: 60.0-70.8%, p < 0.001). Median hearing threshold improved to 10 dB HL (95% CI: 0-45 dB, p < 0.001). Tympanograms shifted toward type A and C (type A: 39.1%, 95% CI: 33.7-44.7, p < 0.001). These improvements were also observed in subgroup analyses of "BET-only" treatment and the indication of "COME" respectively. CONCLUSION: BET is improving a variety of dilatory ET dysfunction-related ear diseases in children. This study provides detailed data for design and planning of prospective studies on BET in children.

Surgical Treatment of a Neuromucoepidermoid Carcinoma of the Left Main Bronchus via Posterolateral Thoracotomy in a 4-Year-Old Boy.

We report the case of a 4-year-old boy with a neuromucoepidermoid carcinoma of the left main bronchus. Complete resection of the carcinoma and reconstruction of the carina between lower and upper lobe by means of an end-to-end anastomosis was performed via a left-sided thoracotomy.

Unnoticed aspiration of palate plate impression material in a neonate: Diagnosis, therapy, outcome.

A 7 week old infant was admitted with respiratory failure. Chest X-ray showed an atelectatic right upper lobe, herniation of right middle and lower lobe into the left thorax, and compression-atelectasis of the left lung. Thoracic CT showed complete occlusion of the right superior bronchus with a radiopaque foreign material. Six weeks prior, an impression for a palate plate using polyvinylsiloxane was taken. The material was removed with a rigid endoscopy, in readiness of extracorporeal oxygenation in case of tracheal obstruction or bronchial rupture. After 4 months of follow-up a hyper reactive airway with recurrent upper and lower airway infections remains.

Non-echoplanar diffusion-weighted MRI in children and adolescents with cholesteatoma: reliability and pitfalls in comparison to middle ear surgery.

BACKGROUND: Currently, there is only limited and contradictory evidence of the role of diffusion-weighted MRI (DW-MRI) in the management of children with cholesteatoma. OBJECTIVE: To provide surgically controlled data that may allow to replace second-look surgery by non-echoplanar DW-MRI in children. MATERIALS AND METHODS: Fifty-five children and adolescents with a median age of 8.6 years (2.2-17.7 years) underwent 61 preoperative half-Fourier acquisition single-shot turbo spin-echo (HASTE) DW-MRI of their petrous bone. Surgical interventions followed within 24 h (79%), within 5 months (20%) or at 18 months (1 case). RESULTS: Surgery detected a cholesteatoma or retraction pocket in 41 of 61 cases (67%). In 49 cases (80%), the MR result was confirmed by surgical findings. Two MR findings were false-positive and 10 false-negative (including cholesteatomas <4 mm). HASTE DW-MRI alone had a sensitivity of 76% and a specificity of 90%. The positive predictive value was 94%, the negative predictive value 64%. In combination with preoperative otoscopy, sensitivity was 90% and negative predictive value 82%. CONCLUSION: DW-MRI correctly detected the majority of lesions but could not reliably exclude small cholesteatomas and empty retraction pockets. We would therefore not generally recommend MR as a substitute for second-look surgery.

Does diffusion-weighted MRI (DW-MRI) change treatment strategy in pediatric cholesteatoma?

CONCLUSION: This review highlights the currently limited and contradictory evidence on the role of diffusion-weighted magnetic resonance imaging (DW-MRI) in the management of pediatric cholesteatoma patients. Available data confirm the need for prospective DW-MRI studies of a larger number of pediatric patients. Factors such as patient compliance, adhesion to follow-up or local logistic circumstances should also be considered. OBJECTIVES: This systematic review aimed to collect and analyze the body of evidence on the usefulness of DW-MRI in first-stage tympanoplasty and in replacing second-look surgery in children with cholesteatoma. METHODS: A comprehensive search of medical databases was conducted. The keywords used were pediatric/paediatric, magnetic resonance imaging, MRI, DW-MRI, cholesteatoma, child, and all meaningful combinations of them. RESULTS: Only one study with 17 patients primarily fulfilled all criteria. Sensitivity, specificity, and positive and negative predictive values were 62%, 88%, 89%, and 58%, respectively. A second study retrospectively analyzed a subset of younger patients (n = 21) of a larger population. Sensitivity, specificity, and positive and negative predictive values were 100%. One additional study described 1 child and 11 adolescents among 32 cases. In all cases the correlation between imaging and surgery findings was 100%. There were no randomized controlled trials and power calculations were not performed.
