Protection Against Invasive Infections in Children Caused by Encapsulated Bacteria.

Front Immunol 2018 20;9:2674. Epub 2018 Nov 20.

Vaccine Evaluation Center, BC Children's Hospital Research Institute, Vancouver, BC, Canada.

The encapsulated bacteria , and (Group B Streptococcus) have been responsible for the majority of severe infections in children for decades, specifically bacteremia and meningitis. Isolates which cause invasive disease are usually surrounded by a polysaccharide capsule, which is a major virulence factor and the key antigen in protective protein-polysaccharide conjugate vaccines. Protection against these bacteria is largely mediated via polysaccharide-specific antibody and complement, although the contribution of these and other components, and the precise mechanisms, vary between species and include opsonophagocytosis and complement-dependent bacteriolysis.

Mechanisms of Blood Brain Barrier Disruption by Different Types of Bacteria, and Bacterial-Host Interactions Facilitate the Bacterial Pathogen Invading the Brain.

Cell Mol Neurobiol 2018 Oct 16;38(7):1349-1368. Epub 2018 Aug 16.

Department of Biomedical Science, Faculty of Medicine and Health Sciences, Universiti Putra Malaysia, 43400 UPM, Serdang, Selangor, Malaysia.

This review aims to elucidate the different mechanisms of blood brain barrier (BBB) disruption that may occur due to invasion by different types of bacteria, as well as to show the bacteria-host interactions that assist the bacterial pathogen in invading the brain. For example, platelet-activating factor receptor (PAFR) is responsible for brain invasion during the adhesion of pneumococci to brain endothelial cells, which might lead to brain invasion. Additionally, the major adhesin of the pneumococcal pilus-1, RrgA is able to bind the BBB endothelial receptors: polymeric immunoglobulin receptor (pIgR) and platelet endothelial cell adhesion molecule (PECAM-1), thus leading to invasion of the brain.

Diagnosing causes of headache within the postpartum period.

J Obstet Gynaecol 2018 Jul;38(5):728

a Obstetrics Department, Ninewells Hospital, University of Dundee , Dundee , UK.

Background: Headache is one of the most common symptoms following delivery and the underlying cause may be benign or life threatening. Identification of the cause of headache in the postpartum period can be challenging and relies on a comprehensive history and thorough examination, with particular focus on the presence or absence of neurological signs, which may suggest a more serious diagnosis (Nelson-Piercy 2010 ). However, through clinical experience and research, we have noted that post-partum headache is significantly under-recognised and treated (Goldszmidt et al. Read More

Can Commun Dis Rep 2017 May 4;43(5):85-88. Epub 2017 May 4.

National Microbiology Laboratory, Public Health Agency of Canada, Winnipeg, MB.

serotype b (Hib) was a major cause of meningitis in children until Hib conjugate vaccine was introduced into the routine infant immunization program and Hib disease in children was almost eliminated. In Alaska, northern Canada and other countries with Indigenous peoples, serotype a (Hia) has emerged as a significant cause of pneumonia, meningitis and septic arthritis especially in children under 24 months of age. A joint government initiative between the Public Health Agency of Canada (PHAC) and the National Research Council of Canada (NRC) was carried out to assess whether an Hia vaccine could be developed for the common good.

Authors:
Janet R Gilsdorf

Clin Infect Dis 2018 Oct;67(9):1445-1449

Department of Pediatrics, University of Michigan Medical School, Ann Arbor.

In 1882, at 19 months of age, Helen Keller developed a febrile illness that left her both deaf and blind. Historical biographies attribute the illness to rubella, scarlet fever, encephalitis, or meningitis. This analysis of her illness suggests she likely had bacterial meningitis, caused by Neisseria meningitidis or possibly Haemophilus influenzae. Read More
