Medical College Documents

Multisystem Inflammatory Syndrome in Children (MIS-C), representing a new entity in the spectrum of manifestations of COVID-19, bears symptomatic resemblance with Kawasaki Disease (KD). This review explores the possible associations between KD and the human coronaviruses and discusses the pathophysiological similarities between KD and MIS-C and proposes implications for the pathogenesis of MIS-C in COVID-19. Since 2005, when a case-control study demonstrated the association of a strain of human coronavirus with KD, several studies have provided evidence regarding the association of different strains of the human coronaviruses with KD. Thus, the emergence of the KD-like disease MIS-C in COVID-19 may …

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Background: Children with acute febrile illness with no localizing signs often receive antibiotics empirically in most resource-poor settings. However, little is known about the burden of bacteremia in this category of patients, and an appraisal is thus warranted. This will guide clinical practice and promote rational antibiotics use.

Methods: We prospectively followed up 140 under-five children who presented with acute undifferentiated fever at the emergency/outpatient pediatric unit of a secondary healthcare facility. Baseline clinical and laboratory information was obtained and documented in a structured questionnaire. We compared baseline characteristics between participants with bacteremia and those without bacteremia. We further fitted …

We conducted a prospective clinical feasibility study of EarlySense’s novel under-mattress MCPM technology in neonates at Pumwani Maternity Hospital in Nairobi, Kenya. To assess feasibility, we compared the performance of EarlySense’s technology to Masimo’s Rad-97 pulse CO-oximeter with capnography technology for heart rate (HR) and respiratory rate (RR) measurements using up-time, clinical event detection performance, and accuracy. Between September 15 and December 15, 2020, we collected and analyzed 470 hours of EarlySense data from …

Extubated Vv-Ecmo For Covid-19 Ards In An Immunosuppressed Pediatric Renal Transplant Patient., Johanna I. Orrick, Cara Holton, Tara Benton, Jenna Miller

Posters

Extracorporeal membrane oxygenation (ECMO) for coronavirus disease 2019 (COVID-19) associated acute respiratory distress syndrome (ARDS) in adults is common, and outcomes are similar to those for non-COVID-19 ARDS on ECMO1. However, children are much less likely to have severe COVID-19 disease, and thus the need for extracorporeal support is rare2,3. Even pediatric solid organ transplant recipients with active COVID-19 infections typically do not require ECMO.4 We present the case of an immunosuppressed pediatric patient with COVID-19-related ARDS who had an excellent outcome on VV-ECMO. An 11-year-old female with a history of polycystic kidney disease status post renal transplant three years …

Purpose:

Radiation epidemiology studies of childhood cancer survivors treated in the pre-computed tomography (CT) era reconstruct the patients’ treatment fields on computational phantoms. For such studies, the phantoms are commonly scaled to age at the time of radiotherapy treatment because age is the generally available anthropometric parameter. Several reference size phantoms are used in such studies, but reference size phantoms are only available at discrete ages (e.g.: newborn, 1, 5, 10, 15, and Adult). When such phantoms are used for RT dose reconstructions, the nearest discrete-aged phantom is selected to represent a survivor of a specific age. In this work, …
