Association of influenza outbreaks with advanced pediatric medical support.

Retrospective data evaluated increases in advanced medical support for children with medically attended acute respiratory illness (MAARI) during influenza outbreak periods (IOP). Advanced support included hospitalisation, intensive care unit admission, or mechanical ventilation, for children aged 0-17 years hospitalised in Maryland's 50 acute-care hospitals over 12 influenza seasons. Weekly numbers of positive influenza tests in the Maryland area defined IOP for each season as the fewest consecutive weeks, including the peak week containing at least 85% of positive tests with a 2-week buffer on either side of the IOP. Peak IOP (PIOP) was defined as four consecutive weeks containing the peak week with the most number of positive influenza tests. Off-PIOP was defined as the 'shoulder' weeks during each IOP. Non-influenza season (NIS) was the remaining weeks of that study season. Rate ratios of mean daily MAARI-related admissions resulting in advanced medical support outcomes during PIOP or Off-PIOP were compared with the NIS and were significantly elevated for all 12 study seasons combined. The results suggest that influenza outbreaks are associated with increased advanced medical support utilisation by children with MAARI. We feel that this data may help preparedness for severe influenza epidemics or pandemic.

Pediatric Trauma.

Emergency department response to the pediatric trauma patient starts with the basics-ABCDE. Certain important differences in pediatric patients, such as airway physiology and drug dosing, must be considered but standardized resources are available. Pediatric blunt and penetrating trauma treatment also have mechanisms and nuances that distinguish them from adult cases. Pediatric literature is slowly growing which can shape evidence-based practice for care including blood transfusions, medications, and procedures.

Big Tests in Little People.

Can laboratory tests that are routinely used in adult patients also be used in pediatric patients? Does the current literature support the routine use of troponin, brain natriuretic peptide, D-dimer, and lactate in children? Adult problems such as acute coronary syndrome and pulmonary embolism are rare in pediatrics, and there is a paucity of literature on how blood tests commonly used to help diagnose these conditions in adults play a role in the diagnosis and management of children. This article presents the literature about 4 common blood tests and examines the clinical applications of each.

55-year-old Male with Fatigue.

This clinicopathological case presentation from the University of Maryland details the initial assessment and management of a 55-year-old, dialysis-dependent man with fatigue. We present how one of our emergency medicine faculty develops her differential when faced with this complaint. She describes how she arrives at the suspected diagnosis and the test she believes is needed to prove her hypothesis. The final surprising diagnosis is then revealed.
