CASE PRESENTATION: Here we describe two pediatric cases of S. pyogenes endocarditis with associated toxic shock. Case 1 was a previously well Caucasian 6-year-old female who presented with sepsis. [ncbi.nlm.nih.gov]

• Varicella-Zoster Virus Infection

  Despite the dramatic increase in invasive Streptococcus pyogenes infections associated with varicella zoster virus infections in recent years, post-varicella S. pyogenes meningitis occurs very rarely. [ncbi.nlm.nih.gov]

• Severe Clinical Course

  Most importantly, it is concluded that recurrent otitis media has to be treated carefully following appropriate identification of the causing organism in order to prevent severe clinical courses of streptococcal infections. [ncbi.nlm.nih.gov]

• Ear Discharge

  • Patients with STSS when GAS is isolated from any sample (pharyngeal smear, wound, skin, ear discharge, etc.). [elsevier.es]

  Taking into account that culture of ear discharge specimens was only performed in cases of suppurative otitis media, it would be fair to assume that the incidence of streptococcal otitis media may be higher than reported in the literature (3–5%). 23 In [analesdepediatria.org]

• Intertrigo

  Abstract We report a 12-month-old infant girl with cervical intertrigo caused by Streptococcus pyogenes. This form of intertrigo has been reported in only five children, but it is clearly underestimated. [ncbi.nlm.nih.gov]

Eleven strains caused recurrent pharyngitis within 40 days after the last treatment, all of them showing the same PFGE-type as the primary strains. Eight of the strains caused recurrence more than 40 days after the treatment. [ncbi.nlm.nih.gov]

The Thomsen- Friedenreich antigen (T antigen) plays a role in the pathophysiology of pneumococcal HUS. We describe the case of a 3-year-old boy with GAS-associated HUS and show how T-antigen exposure was implicated in this case. [ncbi.nlm.nih.gov]

Further studies are needed to determine whether ProT is the pathophysiological target zymogen of SfbX(1-312), to delineate the natural substrate of the SfbX(1-312)·ProT complex, and to elucidate the role of SfbX in the pathology of S. pyogenes infection [bloodjournal.org]
