Retrospective analysis of predisposing factors for difficult lumbar punctures requiring image guidance in pediatric oncology patients.

Pediatr Hematol Oncol 2021 Apr 1:1-14. Epub 2021 Apr 1.

Department of Pediatric Medicine, Division of Anesthesiology, St. Jude Children's Research Hospital, Memphis, Tennessee, USA.

Success rates of lumbar punctures (LPs) in children are reportedly as low as 50%. In addition to procedural complications and failure, difficult LPs are a risk factor for traumatic LPs (TLPs), which can potentially affect diagnostic utility and alter treatment plans for pediatric oncology patients. To identify the intrinsic factors associated with technically difficult LPs in the pediatric oncology population, we performed a retrospective review of patients who required diagnostic imaging modalities for LP procedures at a single pediatric oncology institution between September 2008 and November 2018.

Cardiac tamponade: an educational review.

Eur Heart J Acute Cardiovasc Care 2020 Jul 6. Epub 2020 Jul 6.

Cardiac tamponade is a pericardial syndrome characterised by an impairment of the diastolic filling of the ventricles causing reduction of cardiac output, usually producing signs and symptoms of cardiac arrest, if untreated. The main causes of cardiac tamponade include percutaneous cardiac interventions, malignacies, infectious/inflammatory causes, mechanical complications of myocardial infarction and aortic dissection. The diagnosis of cardiac tamponade is a clinical diagnosis based on a suggestive history and clinical presentation with worsening dyspnoea, distended jugular veins, muffled heart sounds and pulsus paradoxus, and should be confirmed by echocardiography.
