Background and Objective: Streptococcal pharyngitis is one of the most common bacterial infections that its improper treatment could lead to complications such as heart and kidney problems. Although streptococcal pharyngitis makes up a low percentage of pharyngitis etiology, penicillin derivatives are prescribed for many of the patients with pharyngitis. The aim of this study was to determine t...
acute glomerulonephritis (agn) is a type of renal disease which indicates the inflammation of glomerulus and nephrons. this study was carried on 94 children, <15 years old with the diagnosis of agn who were admitted to qom and yazd's hospitals between 2000 and 2006. data were collected using hospital records on admission, progression notes and outpatient follow up. among 94 patients, 55.3% were...
Immune responses against cardiac myosin and group A streptococcal M protein have been implicated in the pathogenesis of rheumatic heart disease. Although cardiac myosin is known to produce myocarditis in susceptible animals, it has never been investigated for its role in production of valvular heart disease, the most serious sequelae of group A streptococcal infection in acute rheumatic fever. ...
OBJECTIVE To assess the utility of clinical features for diagnosis of streptococcal pharyngotonsillitis in pediatrics. METHODS A total of 335 children aged 1-18 years old and presenting clinical manifestations of acute pharyngotonsillitis (APT) were subjected to clinical interviews, physical examinations, and throat swab specimen collection to perform cultures and latex particle agglutination...
BACKGROUND The spectrum of post-streptococcal brain disorders includes chorea, tics, and dystonia. The proposed mediators of disease are anti-basal ganglia (neuronal) antibodies (ABGA). AIM To evaluate ABGA as a potential diagnostic marker in a cohort of UK post-streptococcal movement disorders. METHODS Forty UK children presenting with movement disorders associated with streptococcal infec...
BACKGROUND Some clinicians have questioned the accuracy of rapid diagnosis of group A streptococcal pharyngitis by commercial immunochemical antigen test kits in the setting of recent streptococcal pharyngitis, believing that the false-positive rate was increased because of presumed antigen persistence. METHODS We studied 443 patients--211 cases--who had clinical pharyngitis diagnosed as grou...
Streptococcal toxic shock syndrome (STSS) is a highly lethal, acute-onset illness that is a subset of invasive streptococcal disease. The majority of clinical STSS cases have been associated with the pyrogenic toxin superantigens (PTSAgs) streptococcal pyrogenic exotoxin A or C (SPE A or C), although cases have been reported that are not associated with either of these exotoxins. Recent genome ...
Lymphocyte transformation studies of nonadherent lymphocytes from chronic Chagasic and uninfected persons demonstrated that responses of all individuals to a mouse heart homogenate showed a correlation with responses to streptococcal antigens. Considering the known cross-reactions between streptococcal and cardiac antigens and the high reactivity of Chagasic patients to streptococcal antigens, ...
We describe the case of a 48-year-old man with an acute nephritis and respiratory failure. Clinical history, streptococcal antibody titres and renal biopsy led to a diagnosis of post-streptococcal glomerulonephritis. Respiratory investigations excluded pulmonary oedema and infection. We hypothesize that this man had a co-existing post-streptococcal glomerulonephritis and an immune-mediated pneu...
BACKGROUND Group B streptococcal disease is one of the most common infections in the first week after birth. In 2002, national guidelines recommended universal late antenatal screening of pregnant women for colonization with group B streptococcus to identify candidates for intrapartum chemoprophylaxis. METHODS We evaluated the implementation of the guidelines in a multistate, retrospective co...
