BACKGROUND AND OBJECTIVES: Surfactant protein B deficiency has become increasingly recognized as a cause of severe prolonged respiratory distress. Little has been written about the imaging appearance and the role of imaging in diagnosis. MATERIALS AND METHODS: Three newborn infants with severe respiratory distress exhibited prolonged diffuse pulmonary opacification radiographically. RESULTS: Diffuse ground-glass opacity and markedly prominent interlobular septa suggesting alveolar proteinosis were present on early thin-section chest computed tomographic (CT) images. Fibrotic changes with prominent interlobular septal thickening were present on a later CT. Surfactant protein B deficiency was confirmed by alveolar lavage and peripheral blood DNA analysis. CONCLUSION: Thin-section chest CT imaging contributes important information when this diagnosis is considered.
Despite widespread immunization against Bordetella pertussis, whooping cough remains potentially fatal in susceptible populations such as neonates. A case of neonatal pertussis with severe pulmonary hypertension (PH) requiring extracorporal membrane oxygenation (ECMO) is described. PH associated with pertussis severe enough to require ECMO is frequently irreversible and associated with a poor prognosis.
Extracorporeal membrane oxygenation (ECMO) has been recognized to be beneficial to overcome not only persistent pulmonary hypertension of the newborn, but also cardiopulmonary distress due to neonatal sepsis. However, few papers have reported on the efficacy of ECMO for surgical sepsis in neonates with underlying diseases. This paper reports our experience with ECMO in three newborns with gastric rupture, one of the most serious causes of surgical sepsis in the neonatal period. Over the past 12 years, 14 newborns had gastric rupture; 3 developed lethal cardiopulmonary distress that conservative strategies, including aggressive intensive care, failed to manage, and were selected for ECMO. The clinical data of these patients were retrospectively analyzed. The onset time and duration of ECMO varied from 23 to 143 h of age and 72 to 294 h, respectively. In case 3, complicated by massive intra-abdominal hemorrhage during ECMO, anticoagulants were changed from heparin alone to combined use with nafamostat mesilate, a thrombin inhibitor with a very short half-life. Ultrafiltration or hemodialysis was added in two cases to regulate massive volume overload associated with renal failure. Despite major hemorrhagic complications in two cases, all patients survived. Thus, ECMO may be beneficial in managing neonates with therapy-resistant gastric rupture.
