The prevalence of human papillomavirus in paediatric tonsils in Southwestern Ontario.

Objective: To determine the prevalence of human papillomavirus in paediatric tonsils in Southwestern Ontario, Canada.

Materials And Methods: Patients aged 0-18 years undergoing tonsillectomy were recruited. Two specimens (left and right tonsils) were collected from each participant.

A national study of choanal atresia in tertiary care centers in Canada - part II: clinical management.

Background: To evaluate the clinical management of choanal atresia (CA) in tertiary centers across Canada.

Methods: Multi-centre case series involving six tertiary care pediatric hospitals across Canada. Retrospective chart review of patients born between 1980 and 2010 diagnosed with choanal atresia to a participating center.

A national study of choanal atresia in tertiary care centers in Canada - part I: clinical presentation.

Background: To evaluate the clinical presentation of choanal atresia (CA) in tertiary centers across Canada.

Methods: Multi-centre case series involving six tertiary care pediatric hospitals across Canada. Retrospective chart review of patients born between 1980 and 2010 diagnosed with CA at a participating center.

Group B Streptococcal Cellulitis and Necrotizing Fasciitis in Infants: A Systematic Review.

Background: There is no consensus regarding approaches to infantile group B streptococcal (GBS) head and neck cellulitis and necrotizing fasciitis. We present a case of GBS necrotizing cellulitis and summarize the literature regarding the presentation and management of infantile head and neck GBS cellulitis and necrotizing fasciitis.

Methods: The literature was searched using PubMed, Web of Science, EMBASE and Medline (inception to April 2017) by 2 independent review authors.

Expression of immunohistochemical markers on microglia in Creutzfeldt-Jakob disease and Alzheimer's disease: morphometric study and review of the literature.

Introduction: Microglia are the resident immune cells of the CNS. They are involved in the pathogenesis of diverse neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease, prion diseases as well as multiple sclerosis, amyotrophic lateral sclerosis and AIDS dementia complex. Activated microglia up-regulate many surface receptors such as the major histocompatibility complex (MHC) or complement receptors and secrete a variety of soluble biologically active factors, which are either neurotrophic (e.

[Prevalence of potentially reversible cognitive function disorders in patients of a memory dysfunction clinic].

Unlabelled: Potentially reversible dementias are rarely detected in out-patient care facilities. Actual reversibility is virtually not known and has been occasionally reported in literature.

Aim: To determine the prevalence of potentially reversible dementias among patients seen at the ambulatory care facility and to estimate their "real life" reversibility.

Microglial cells in neurodegenerative disorders.

Microglia are resident immune cells of the CNS. They are involved in the pathogenesis of diverse neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, prion diseases as well as multiple sclerosis, amyotrophic lateral sclerosis and AIDS dementia complex. It is widely accepted that microglia contribute to the neurodegeneration through a release of a variety of proinflammatory substances.

["7 Minute Screening. Part II: the evaluation of the test sensitivity and specificity as compared to Mini-Mental State examination].

In the paper an evaluation of basic accuracy parameters (sensitivity and specificity) of the polish version of "7 Minute Screen" as a screening tool for Alzheimer's disease is presented as well as its comparison to Mini Mental State.
