Radiation dose assessment of pediatric computed tomography of the chest: the need to consider patient size.

Objective: To evaluate the radiation dose of chest computed tomography (CT) examinations of pediatric patients and the extent to which volume CT dose index (CTDIvol) underestimates radiation dose in comparison to size specific dose estimates (SSDE).

Methods: Single-center, retrospective study of consecutive unenhanced pediatric (age <18 years) chest CTs between October 2015 and October 2016. Radiation dose as well as demographic and clinical data were recorded from 133 chest CTs.

Sensory-Motor-Oral Stimulation Combined with Early Sucking During the Mandibular Distraction Osteogenesis Process in Children with Robin Sequence.

Objective: To describe the findings of children with Robin Sequence (RS) who received sensory-motor-oral stimulation combined with early sucking during mandibular distraction osteogenesis (MDO), compared with children who did not receive the intervention.

Design: A quasi-experimental study. Setting: A tertiary public hospital.

Clinical outcomes before and after videofluoroscopic swallow study in children 24 months of age or younger.

Objective: To evaluate the combined impact of videofluoroscopic swallow study (VFSS) and therapeutic feeding and swallowing interventions on clinical outcomes in children with oropharyngeal dysphagia (OPD).

Methods: This was an uncontrolled longitudinal analytical study in which OPD patients were evaluated before and after VFSS. Children ≤ 24 months of age diagnosed with OPD in a clinical setting and undergoing VFSS for investigation and management of OPD were included in the study.

Endoscopic evaluation of neonates with signs of upper airway obstruction in the neonatal unit of a tertiary hospital.

Introduction: The aim of the study is to evaluate major causes of upper airway obstruction in newborns receiving healthcare at our institution, their method of endoscopic assessment and the rate of complications related to these procedures.

Materials And Methods: This is a case series study of patients from institutional neonatal intensive care unit (NICU) presenting signs of ventilatory dysfunction for whom an endoscopic airway assessment was warranted. Information of interest was collected from medical records according to a Clinical and Endoscopic Assessment Protocol created for the study.

Brazilian guidelines for the pharmacological treatment of the pulmonary symptoms of cystic fibrosis. Official document of the Sociedade Brasileira de Pneumologia e Tisiologia (SBPT, Brazilian Thoracic Association).

Cystic fibrosis (CF) is a genetic disease that results in dysfunction of the CF transmembrane conductance regulator (CFTR) protein, which is a chloride and bicarbonate channel expressed in the apical portion of epithelial cells of various organs. Dysfunction of that protein results in diverse clinical manifestations, primarily involving the respiratory and gastrointestinal systems, impairing quality of life and reducing life expectancy. Although CF is still an incurable pathology, the therapeutic and prognostic perspectives are now totally different and much more favorable.
