Serum levels of 3 group A streptococcal antibodies were determined in 53 patients prior to mitral commissurotomy and monthly for 3 to 6 months postoperatively. Significant elevation of antibody titers was relatively infrequent prior to commissurotomy and the presence of chronic productive inflammatory lesions in the biopsied atrial appendage was usually unrelated to recent streptococcal infecti...

Post streptococcal syndromes may manifest in multiple organs including the musculoskeletal, central nervous, urinary, integumentary, and circulatory systems. The commonly described post streptococcal syndromes include acute rheumatic fever, post streptococcal glomerulonephritis, post streptococcal arthritis, and pediatric autoimmune neuropsychiatric disorders. Classically, these complications o...

Acute streptococcal gingivitis is an acute infection of the oral mucosa. Specific bacterial infections such as to Neisseria gonorrhea, Treponema pallidum, Streptococcal species, and others are very important, but little attention is given to these diseases because they are rarely seen. The purpose of this study was to report the case of an acute streptococcal gingivitis in a patient and to desc...

Neonatal group B streptococcal infection is the primary cause of neonatal morbidity related to infection. It can often be prevented by identifying and treating pregnant women who carry group B streptococci or who are at highest risk of transmitting the bacteria to newborns. Increasing evidence and expert opinion support intrapartum treatment of women at relatively high risk of delivering an inf...

Autism Spectrum Disorders (ASD) is a group of neurodevelopment dysfunctions causing behavioral abnormalities in social, verbal and non-verbal communication. The precise aetiology of ASD is unknown but it is likely to be the outcome of a combination of genetic, neurological, environmental and immunological factors. Streptococcal infection can induce tick disorders and obsessive compulsive disord...

Objectives: Pediatric acute-onset neuropsychiatric syndrome (PANS) and its subset, pediatric autoimmune neuropsychiatric disorder associated with streptococcal infection (PANDAS), are emerging autoimmune encephalopathies of childhood. Management guidelines are needed. This article, from the PANS PANDAS Consortium, presents a consensus management guideline for the infection components. Accompany...

INTRODUCTION Henoch-Schönlein purpura is a systemic disease with frequent renal involvement, characterized by IgA mesangial deposits. Streptococcal infection can induce an abnormal IgA immune response like Henoch-Schönlein purpura, quite similar to typical acute post-infectious glomerulonephritis. Indeed, hypocomplementemia that is typical of acute glomerulonephritis has also been described in ...

Serum levels of 3 group A streptococcal antibodies were determined in 53 patients prior to mitral commissurotomy and monthly for 3 to 6 months postoperatively. Significant elevation of antibody titers was relatively infrequent prior to commissurotomy and the presence of chronic productive inflammatory lesions in the biopsied atrial appendage was usually unrelated to recent streptococcal infecti...

Group B streptococcus is known to be a leading cause of neonatal infection, but less appreciated is the fact that it causes maternal infection also. Maternal group B streptococcal infections during pregnancy and delivery threaten not only the mother, but the child as well. Postpartum infection, such as mastitis, bacteremia, sepsis, meningitis, endometritis, and wound infections are hazards to t...
