RESUMO

Adenotonsillectomy is the most common indication for sleep-disordered breathing in children. Measuring pharyngeal closing pressures in anaesthetised children allows identification of severe obstructive sleep apnoea. This technique could help quantify immediate surgical impact and risk stratify postoperative treatment in these patients.

RESUMO

The current available literature evaluating pediatric multidisciplinary aerodigestive programs for the management of aerodigestive disorders in infants was reviewed. Multidisciplinary aerodigestive programs have emerged to provide coordinated and comprehensive care for the growing population of children with aerodigestive conditions, including complex airway, pulmonary, gastrointestinal, and feeding disorders, which are prevalent among infants discharged from the neonatal intensive care unit (NICU). The team approach central to aerodigestive clinics offers a comprehensive diagnostic workup and unified management plan through consolidated interdisciplinary clinics, combined endoscopic procedures, and regular team discussions, leading to improved resource utilization and health care outcomes. We review common conditions presenting in the NICU that benefit from the aerodigestive model of care, including esophageal atresia, prematurity, bronchopulmonary dysplasia with or without tracheostomy or ventilator dependence, and dysphagia.

RESUMO

PURPOSE: Primary ciliary dyskinesia (PCD) is a rare disorder of the mucociliary clearance leading to recurrent upper and lower respiratory tract infections. PCD is difficult to clinically distinguish from other entities leading to recurrent oto-sino-pulmonary infections, including primary immunodeficiency (PID). Nasal nitric oxide (nNO) is a sensitive and specific diagnostic test for PCD, but it has not been thoroughly examined in PID. Past publications have suggested an overlap in nNO levels among subjects with PCD and PID. We sought to determine if nNO measurements among patients diagnosed with PID would fall significantly above the established PCD diagnostic cutoff value of 77 nL/min. METHODS: Children > 5 years old and adults with definitive PID or PCD diagnoses were recruited from outpatient subspecialty clinics. Participants underwent nNO testing by standardized protocol using a chemiluminescence analyzer and completed a questionnaire concerning their chronic oto-sino-pulmonary symptoms, including key clinical criteria specific to diagnosed PCD (neonatal respiratory distress at term birth, year-round cough or nasal congestion starting before 6 months of age, any organ laterality defect). RESULTS: Participants included 32 patients with PID, 27 patients with PCD, and 19 healthy controls. Median nNO was 228.9.1 nL/min in the PID group, 19.7 nL/min in the PCD group, and 269.4 in the healthy controls (p < 0.0001). Subjects with PCD were significantly more likely to report key clinical criteria specific to PCD, but approximately 25% of PID subjects also reported at least 1 of these key clinical criteria (mainly year-round cough or nasal congestion). CONCLUSIONS: While key clinical criteria associated with PCD often overlap with the symptoms reported in PID, nNO measurement by chemiluminescence technology allows for effective discrimination between PID and PCD.

RESUMO

BACKGROUND: Primary ciliary dyskinesia (PCD) is a rare disorder of motile cilia associated with situs abnormalities. At least 12% of patients with PCD have situs ambiguus (SA), including organ laterality defects falling outside normal arrangement (situs solitus [SS]) or mirror image inversion (situs inversus totalis [SIT]). RESEARCH QUESTION: Do patients with PCD and SA achieve worse clinical outcomes compared with those with SS or SIT? STUDY DESIGN AND METHODS: This cross-sectional, multicenter study evaluated participants aged 21 years or younger with PCD. Participants were classified as having SA, including heterotaxy, or not having SA (SS or SIT). Markers of disease severity were compared between situs groups, adjusting for age at enrollment and severe CCDC39 or CCDC40 genotype, using generalized linear models and logistic and Poisson regression. RESULTS: In 397 participants with PCD (mean age, 8.4 years; range, 0.1-21), 42 patients were classified as having SA, including 16 patients (38%) with complex cardiovascular malformations or atrial isomerism, 13 patients (31%) with simple CVM, and 13 patients (31%) without cardiovascular malformations. Of these, 15 patients (36%) underwent cardiac surgery, 24 patients (57%) showed an anatomic spleen abnormality, and seven patients (17%) showed both. The remaining 355 participants did not have SA, including 152 with SIT and 203 with SS. Overall, 70 participants (17%) harbored the severe CCDC39 or CCDC40 genotype. Compared with participants without SA, those with SA showed lower median BMI z scores (P = .03), lower FVC z scores (P = .01), and more hospitalizations and IV antibiotic courses for acute respiratory infections during the 5 years before enrollment (P < .01). Participants with cardiovascular malformations requiring surgery or with anatomic spleen abnormalities showed lower median BMI z scores and more hospitalizations and IV therapies for respiratory illnesses compared with participants without SA. INTERPRETATION: Children with PCD and SA achieve worse nutritional and pulmonary outcomes with more hospitalizations for acute respiratory illnesses than those with SS or SIT combined. Poor nutrition and increased hospitalizations for respiratory infections in participants with SA and PCD are associated with cardiovascular malformations requiring cardiac surgery, splenic anomalies, or both.

RESUMO

BACKGROUND: Organ laterality defects in primary ciliary dyskinesia (PCD) are common, ranging from complete mirror image organ arrangement, situs inversus totalis (SIT), to situs ambiguus (SA), which falls along the spectrum of situs solitus (SS) and SIT. Targeted investigations for organ laterality defects are not universally recommended in PCD consensus statements. Without investigations beyond chest radiography (CXR), clinically significant defects may go undetected leading to increased morbidity. We hypothesize that clinically significant SA defects remain undetected on CXR and targeted investigations are needed to detect various laterality defects associated with morbidity. METHODS: This retrospective study collected data from PCD clinics at two Canadian children's hospitals from 2012 to 2020. Participants <30 years old with a confirmed or clinical diagnosis of PCD were enrolled. CXR images were reviewed, and reports of other targeted investigations, including chest computed tomography, abdominal ultrasound, echocardiogram, upper gastrointestinal series, and splenic function studies, were extracted from medical records. Situs classifications from CXR alone versus CXR with add-on targeted investigations were compared using Cochran's q and McNemar tests. RESULTS: One hundred and fifty-nine PCD patients were included, median age at PCD diagnosis of 6.1 years (range: 0-28). The situs classification differed significantly from CXR images alone versus CXR with add-on targeted investigations (p < 0.001); SS 88 (55%) versus 75 (47%), SIT 59 (37%) versus 46 (29%), and SA 12 (8%) versus 38 (24%). Identified SA defects were cardiovascular (21, 13%), intestinal (9, 6%), and/or splenic (16,10%). CONCLUSIONS: In PCD patients, clinically significant SA defects may not be detected by CXR alone. Our results suggest that the routine use of CXR with add-on targeted investigations may be justified.
