Splenic Embolization After Trauma: An Opportunity to Improve Best Immunization Practices.

J Surg Res 2018 Dec 14;232:293-297. Epub 2018 Jul 14.

Trauma/Critical Care Division, University of Kansas Medical Center, Kansas City, Kansas. Electronic address:

Background: The spleen is the second most commonly injured solid organ during blunt abdominal trauma. Although total splenectomy is frequently performed for injury, splenic rupture can also be managed by splenic embolization. For these patients, current Advisory Committee on Immunization Practices (ACIP) recommendations indicate that if 50% or more of the splenic mass is lost, patients should be treated as though they are asplenic.

, a candidate gene for isolated congenital asplenia, is required for pre-rRNA processing and spleen formation in .

Development 2018 Oct 18;145(20). Epub 2018 Oct 18.

Pediatric Genomics Discovery Program, Departments of Pediatrics and Genetics, Yale University School of Medicine, 333 Cedar Street, New Haven, Connecticut 06510, USA

A growing number of tissue-specific inherited disorders are associated with impaired ribosome production, despite the universal requirement for ribosome function. Recently, mutations in RPSA, a protein component of the small ribosomal subunit, were discovered to underlie approximately half of all isolated congenital asplenia cases. However, the mechanisms by which mutations in this ribosome biogenesis factor lead specifically to spleen agenesis remain unknown, in part due to the lack of a suitable animal model for study.

Disharmonious Patterns of Heterotaxy and Isomerism: How Often Are the Classic Patterns Breached?

Circ Cardiovasc Imaging 2018 Feb;11(2):e006917

From the Labatt Family Heart Centre (D.Y., H.N., L.G.-W., M.S., E.J., S.-J.Y.) and Department of Diagnostic Imaging (C.Z.L., L.G.-W., M.S., S.-J.Y.), The Hospital for Sick Children, Toronto, Canada; and Department of Pediatrics, University of Toronto, Canada (L.G.-W., M.S., E.J., S.-J.Y.).

Background: It is advocated that heterotaxy should be segregated into right or left isomerism according to atrial appendage morphology. However, atrial situs determination is often based on the pattern of associated findings rather than on atrial morphology itself, which can be difficult to define. The objective was to assess how often concordant patterns of isomerism classified by atrial appendage morphology, bronchopulmonary pattern, and splenic status are breached using cardiac magnetic resonance or computed tomography.

Fulminant Haemophilus Influenzae Type a Infection in a 4-year-old with Previously Undiagnosed Asplenic Heterotaxy.

Pediatr Infect Dis J 2018 Apr;37(4):e108-e110

From the Department of Pediatrics, Global Child Health Residency Program, Baylor College of Medicine, Houston, Texas, Division of Hospital Medicine, Department of Pediatrics, University of Alabama at Birmingham, and Division of Infectious Disease, Department of Pediatrics, University of Alabama at Birmingham, Birmingham, Alabama.

The post Hib-vaccine era has resulted in increased cases of invasive, non-Hib, Haemophilus influenzae infections. One of the encapsulated species, type a, displays the most similarity in virulence to type b. Our patient, a fully vaccinated 4-year-old female, with newly diagnosed asplenia in the setting of heterotaxy, had a prolonged hospital course with disseminated Haemophilus influenzae type a infection.

Development of quality metrics for ambulatory pediatric cardiology: Infection prevention.

Congenit Heart Dis 2017 Dec 25;12(6):756-761. Epub 2017 Jul 25.

Division of Pediatric Cardiology, Department of Pediatrics, Cincinnati Children's Hospital, Cincinnati, Ohio, USA.

Introduction: In 2012, the American College of Cardiology's (ACC) Adult Congenital and Pediatric Cardiology Council established a program to develop quality metrics to guide ambulatory practices for pediatric cardiology. The council chose five areas on which to focus their efforts; chest pain, Kawasaki Disease, tetralogy of Fallot, transposition of the great arteries after arterial switch, and infection prevention. Here, we sought to describe the process, evaluation, and results of the Infection Prevention Committee's metric design process. Read More

Natural IgM antibodies in the immune defence against neoehrlichiosis.

Infect Dis (Lond) 2017 Nov - Dec;49(11-12):809-816. Epub 2017 Jul 6.

e Department of Clinical and Experimental Medicine , Linköping University , Linköping , Sweden.

Background: Neoehrlichiosis is an infectious disease caused by the tick-borne bacterium "Candidatus Neoehrlichia mikurensis". Splenectomy and rituximab therapies are risk factors for severe neoehrlichiosis. Our aim was to examine if neoehrlichiosis patients had low levels of natural IgM antibodies and/or were hypogammaglobulinemic, and if such deficiencies were associated with asplenia and vascular complications.
