Presentations and outcomes of familial hemophagocytic lymphohistiocytosis in the pediatric intensive care units (PICUs).

Objectives: We aimed to describe Familial Hemophagocytic Lymphohistiocytosis (F-HLH) patients' clinical features, intensive care courses, and outcomes.

Methods: Multi-center retrospective cohort study of pediatric patients diagnosed with F-HLH from 2015 to 2020 in five tertiary centers in Saudi Arabia. Patients were classified as F-HLH based on their genetic confirmation of known mutation or on their clinical criteria, which include a constellation of abnormalities, early disease onset, recurrent HLH in the absence of other causes, or a family history of HLH.

Use of Ceftolozane/tazobactam for the Treatment of Multidrug-resistant Pneumonia in a Pediatric Patient with Combined Immunodeficiency (CID): A Case Report from a Tertiary Hospital in Saudi Arabia.

Infections, with multidrug-resistant a, are a major concern in the pediatric intensive care unit, especially in immunocompromised patients. Some of these strains are resistant to all beta-lactams, including carbapenems, leaving very limited treatment options remaining. These options include aminoglycosides and colistin, both of which have poor pharmacokinetic profiles with significant toxicities.

Central venous lines are a risk factor for chylothorax in infants after cardiac surgery.

Objective: Chylothorax complicates congenital heart disease (CHD) surgery and may be associated with significant morbidity. Etiology of chylothorax is multifactorial, and it has been associated with deep venous thrombosis and obstruction from central venous lines (CVLs) in patients without CHD. We sought to determine whether CVL insertion site was associated with the occurrence of chylothorax in infants after cardiac surgery.

Successful continuous renal replacement therapy using two single-lumen catheters in neonates and infants with cardiac disease.

Background: Acute kidney injury (AKI) frequently occurs in neonates and infants after cardiopulmonary bypass (CPB) and may require renal replacement therapy (RRT). Peritoneal dialysis (PD) is the RRT modality of choice in neonates with AKI after CPB, but continuous renal replacement therapy (CRRT) may be necessary if PD is ineffective or contraindicated. Vascular access is challenging in this population, in part, due to small central vein size that may preclude placement.

Ischemia from extrinsic compression of the brachial artery by a stent in the venous outflow of a brachio-basilic arterio-venous graft.

Distal artery embolization is a well-known complication after mechanical thrombectomy, manifesting as limb ischemia. We describe a case of ischemia that developed after mechanical thrombectomy and stent placement in the venous anastomosis of a brachio- basilic arterio-venous graft. Subsequent investigations revealed that the stent had extrinsically compressed the adjacent brachial artery.
