    First documented case of pulmonary alveolar proteinosis with atopy presenting secondary to CSFR2B mutation
    (2022-08-01) KIYAN, GÜRSU; Sasihuseyinoglu A. S. , ÖZCAN D., Avci A., KIYAN G.
    Pulmonary alveolar proteinosis (PAP) is a rare lung disorder in which surfactant-derived lipoproteins accumulate excessively within pulmonary alveoli, causing severe respiratory distress. It is essential to gain a better understanding of the signs to clinically diagnose PAP and include PAP among the differential diagnoses of interstitial pulmonary diseases or other diseases with similar manifestations. We describe a 2.5-year patient with atopy who presented with pulmonary infiltration, recurrent wheezing, and cough despite steroid and salbutamol administration via inhalation. High-resolution computed tomography revealed crazy-paving patterns in both lungs, suggesting PAP. An open lung biopsy revealed intra-alveolar granular amphophilic material, which was strongly positive on periodic acid-Schiff staining. The results of pulmonary-associated surfactant protein B and C gene analyses were normal. However, granulocyte-macrophage colony-stimulating factor receptor beta-protein was not detected in leucocytes, and a novel mutation was identified in the CSF2RB gene. The patient was diagnosed with PAP and treated with whole-lung lavage. Key Words: Pulmonary alveolar proteinosis, Child, Atopy, Wheezing.

    The effect of postoperative ventilation strategies on postoperative complications and outcomes in patients with esophageal atresia: Results from the Turkish Esophageal Atresia Registry

    © 2022 Wiley Periodicals LLC.Objectives: Postoperative ventilatory strategies in patients with esophageal atresia (EA) and tracheoesophageal fistula (TEF) may have an impact on early postoperative complications. Our national Esophageal Atresia Registry was evaluated to define a possible relationship between the type and duration of respiratory support on postoperative complications and outcome. Study Design: Among the data registered by 31 centers between 2015 and 2021, patients with esophago-esophageal anastomosis (EEA)/tracheoesophageal fistula (TEF) were divided into two groups; invasive ventilatory support (IV) and noninvasive ventilatory support and/or oxygen support (NIV-OS). The demographic findings, gestational age, type of atresia, associated anomalies, and genetic malformations were evaluated. We compared the type of repair, gap length, chest tube insertion, follow-up times, tensioned anastomosis, postoperative complications, esophageal dilatations, respiratory problems requiring treatment after the operation, and mortality rates. Results: Among 650 registered patients, 502 patients with EEA/TEF repair included the study. Four hundred and seventy of patients require IV and 32 of them had NIV-OS treatment. The IV group had lower mean birth weights and higher incidence of respiratory problems when compared to NIV-OS group. Also, NIV-OS group had significantly higher incidence of associated anomalies than IV groups. The rates of postoperative complications and mortality were not different between the IV and NIV-OS groups. Conclusion: We demonstrated that patients who required invasive ventilation had a higher incidence of low birth weight and respiratory morbidity. We found no relation between mode of postoperative ventilation and surgical complications. Randomized controlled trials and clinical guidelines are needed to define the best type of ventilation strategy in children with EA/TEF.
