Severe tricuspid regurgitation resulting from a flail leaflet is a rare cause of neonatal cyanosis. We report two neonates with profound cyanosis and severe tricuspid regurgitation caused by rupture of the papillary muscle supporting the anterior leaflet, without other structural heart defects. Ductal patency could not be established. Repair of the(More)
OBJECTIVE To report the successful use of extracorporeal membrane oxygenation (ECMO) as rescue therapy for severe necrotizing pneumonia secondary to infection by the Staphylococcus aureus species. DESIGN Case series. SETTING Pediatric intensive care unit at a freestanding tertiary care children's hospital. PATIENTS Two pediatric patients with severe(More)
OBJECTIVE To describe survival to intensive care unit (ICU) discharge and 6-month survival in a large cohort of pediatric oncology patients with severe sepsis. DESIGN Retrospective analysis. SETTING The ICU of a single pediatric oncology center. PATIENTS Patients with cancer admitted to the ICU of St. Jude Children's Research Hospital between January(More)
Extracorporeal membrane oxygenation (ECMO) is a lifesaving therapy, which has been used for the support of children with a broad range of diseases. Two pumps of differing mechanisms have been used to generate the extracorporeal flow: roller-head pumps and centrifugal pumps. Seven patients supported during ECMO with Levitronix Centrimag (Centrimag group(More)
T-lymphocyte subsets when measured in steroid responsive nephrotic syndrome (SRNS) have demonstrated significant variance from normal values. T-cell subsets were studied by using two-color flow cytometric analysis in 32 children (9.2 +/- 5 years of age) with SRNS. The children were divided into four groups: a) SRNS in acute relapse, on prednisone; b) SRNS(More)
OBJECTIVE To assess the following hypotheses regarding mechanically ventilated pediatric oncology patients, including those receiving hematopoietic stem cell transplant (HSCT) and those not receiving HSCT: 1) outcomes are more favorable for nontransplant oncology patients than for those requiring HSCT; 2) outcomes have improved for both populations over(More)
Intraosseous infusion is a well accepted means of obtaining emergency intravascular access in children. Despite the low incidence of serious complications from intraosseous infusions, the potential exists for growth plate injury and subsequent growth disturbance following intraosseous infusion. We conducted a prospective, blinded observational study of 10(More)
Radiographic procedures performed at a 100-bed pediatric hospital were reviewed jointly by a radiologist and the primary physician staff. The reviewers judged several procedures to be performed unnecessarily, with undue patient risk or cost. Low efficacy examinations were divided into two categories: (1) low-yield examinations with significant gonadal(More)
AIM To describe our experience using extracorporeal cardiopulmonary resuscitation (ECPR) in resuscitating children with refractory cardiac arrest in the intensive care unit (ICU) and to describe hospital survival and neurologic outcomes after ECPR. METHODS A retrospective chart review of a consecutive case series of patients requiring ECPR from 2001 to(More)
We report the case of a 22-month-old immunocompetent male child with fibrosing mediastinitis secondary to zygomycosis, an unusual presentation of a rare fungal infection. This patient was successfully treated with amphotericin B and itraconazole for 20 weeks. Stenting of the superior vena cava was helpful in relieving the patient's superior vena cava(More)
