Genomic differences among past Streptococcus pyogenes serotype M3 strains isolated in 1973 and before from patients with streptococcal pharyngitis, recent (1990s) serotype M3 clinical isolates from patients with pharyngitis, and recent M3 isolates from patients with toxic shock-like syndrome were investigated by restriction landmark genomic scanning and by modified random-amplified polymorphic ...

OBJECTIVES To determine the efficacy, tolerability, and safety of an aqueous extract of Costus speciosus (C. speciosus) rhizome in pediatric and adult patients suffering from acute pharyngitis and tonsillitis as an alternative to antibiotics use. METHODS This pilot cohort trial was conducted at King Abdulaziz University in Saudi Arabia between May and December 2014, among 15 patients with acu...

The Q Test Strep (Becton Dickinson and Co., Franklin Lakes, N.J.) is a new solid-phase liposome immunoassay for the rapid diagnosis of group A beta-hemolytic streptococcal pharyngitis. Compared with blood agar plate cultures, the Q Test Strep had a sensitivity of 91%, a specificity of 83%, a positive predictive value of 88%, and a negative predictive value of 87%. Liposome technology can be use...

In this report, we evaluated the case history of a patient with longstanding chronic pharyngitis who had periodic clinical manifestation for three years after a flu vaccine administration, and after various treatments tried to resolve the chronic pharyngitis with unsuccessful antibiotic and anti-inflammatory therapies. The patient occasionally presented a slight ocular inflammation, while dysur...

Objective-To evaluate treatment of group A ( haemolytic streptococcal pharyngitis with amoxycillin once daily compared with phenoxymethylpenicillin three or four times a day. Design-Randomised controlled study of consecutive patients presenting with symptoms suggestive of group A ( haemolytic streptococcal pharyngitis in whom culture ofa throat swab yielded positive results. Setting-Five family...

INTRODUCTION In group A streptococcal (GAS) pharyngitis a ten-day course of amoxicillin is recommended. However, short-course treatments seem to be equally effective. The aim of this study was to retrospectively evaluate and compare the outcome of patients treated with 7-day course and 10-day course of amoxicillin. MATERIALS AND METHODS Retrospective analysis of all GAS pharyngitis admitted t...

Streptococcal inhibitor of complement (Sic) is a highly polymorphic extracellular protein made predominantly by serotype M1 group A Streptococcus (GAS). New variants of the Sic protein frequently appear in M1 epidemics as a result of positive natural selection. To gain further understanding of the molecular basis of M1 epidemics, the sic gene was sequenced from 471 pharyngitis and 127 pyogenic ...

Primary prevention of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) in children depends on prompt and effective diagnosis and treatment of pharyngitis at the primary level of care. Cost-effectiveness modeling shows that the most cost-effective strategy for primary prevention in South Africa (SA) is to use a simple symptomatic clinical decision rule (CDR) to diagnose pharyngitis ...
