Toxic Shock Syndrome Contributors: Noah Craft MD, Phd, Lindy P
** no patient handout Toxic shock syndrome Contributors: Noah Craft MD, PhD, Lindy P. Fox MD, Lowell A. Goldsmith MD, MPH SynopsisToxic shock syndrome (TSS) is a severe exotoxin-mediated bacterial infection that is characterized by high fevers, headache, pharyngitis, vomiting, diarrhea, and hypotension. Two subtypes of TSS exist, based on the bacterial etiology: Staphylococcus aureus and group A streptococci. Significantly, the severity of TSS can range from mild disease to rapid progression to shock and end organ failure. The dermatologic manifestations of TSS include the following: • Erythema of the palms and soles that desquamates 1-3 weeks after the initial onset • Diffuse scarlatiniform exanthem that begins on the trunk and spreads toward the extremities • Erythema of the mucous membranes (strawberry tongue and conjunctival hyperemia) TSS was identified in and most commonly affected menstruating young white females using tampons in the 1980s. Current TSS cases are seen in post-surgical interventions in men, women, and children, as well as in other settings, in addition to cases of menstrual TSS, which have declined with increased public education on tampon usage and TSS. One study in Japanese patients found the highest TSS incidence to occur among children with burns, as Staphylococcus colonization is high in this subgroup and antibody titers are not yet sufficient to protect children from the exotoxins causing TSS. Staphylococcal TSS is caused by S. aureus strains that can produce the toxic shock syndrome toxin-1 (TSST-1). TSST-1 is believed to cause disease via direct effects on end organs, impairing clearance of gut flora derived endotoxins, with TSST-1 acting as a superantigen leading to massive nonspecific activation of T-cells and subsequent inflammation and vascular leakage. -
The Role of Streptococcal and Staphylococcal Exotoxins and Proteases in Human Necrotizing Soft Tissue Infections
toxins Review The Role of Streptococcal and Staphylococcal Exotoxins and Proteases in Human Necrotizing Soft Tissue Infections Patience Shumba 1, Srikanth Mairpady Shambat 2 and Nikolai Siemens 1,* 1 Center for Functional Genomics of Microbes, Department of Molecular Genetics and Infection Biology, University of Greifswald, D-17489 Greifswald, Germany; [email protected] 2 Division of Infectious Diseases and Hospital Epidemiology, University Hospital Zurich, University of Zurich, CH-8091 Zurich, Switzerland; [email protected] * Correspondence: [email protected]; Tel.: +49-3834-420-5711 Received: 20 May 2019; Accepted: 10 June 2019; Published: 11 June 2019 Abstract: Necrotizing soft tissue infections (NSTIs) are critical clinical conditions characterized by extensive necrosis of any layer of the soft tissue and systemic toxicity. Group A streptococci (GAS) and Staphylococcus aureus are two major pathogens associated with monomicrobial NSTIs. In the tissue environment, both Gram-positive bacteria secrete a variety of molecules, including pore-forming exotoxins, superantigens, and proteases with cytolytic and immunomodulatory functions. The present review summarizes the current knowledge about streptococcal and staphylococcal toxins in NSTIs with a special focus on their contribution to disease progression, tissue pathology, and immune evasion strategies. Keywords: Streptococcus pyogenes; group A streptococcus; Staphylococcus aureus; skin infections; necrotizing soft tissue infections; pore-forming toxins; superantigens; immunomodulatory proteases; immune responses Key Contribution: Group A streptococcal and Staphylococcus aureus toxins manipulate host physiological and immunological responses to promote disease severity and progression. 1. Introduction Necrotizing soft tissue infections (NSTIs) are rare and represent a more severe rapidly progressing form of soft tissue infections that account for significant morbidity and mortality [1]. -
Investigation of Anthrax Associated with Intentional Exposure
October 19, 2001 / Vol. 50 / No. 41 889 Update: Investigation of Anthrax Associated with Intentional Exposure and Interim Public Health Guidelines, October 2001 893 Recognition of Illness Associated with the Intentional Release of a Biologic Agent 897 Weekly Update: West Nile Virus Activity — United States, October 10–16, 2001 Update: Investigation of Anthrax Associated with Intentional Exposure and Interim Public Health Guidelines, October 2001 On October 4, 2001, CDC and state and local public health authorities reported a case of inhalational anthrax in Florida (1 ). Additional cases of anthrax subsequently have been reported from Florida and New York City. This report updates the findings of these case investigations, which indicate that infections were caused by the intentional release of Bacillus anthracis. This report also includes interim guidelines for postexposure pro- phylaxis for prevention of inhalational anthrax and other information to assist epidemi- ologists, clinicians, and laboratorians responding to intentional anthrax exposures. For these investigations, a confirmed case of anthrax was defined as 1) a clinically compatible case of cutaneous, inhalational, or gastrointestinal illness* that is laboratory confirmed by isolation of B. anthracis from an affected tissue or site or 2) other labora- tory evidence of B. anthracis infection based on at least two supportive laboratory tests. A suspected case was defined as 1) a clinically compatible case of illness without isola- tion of B. anthracis and no alternative diagnosis, but with laboratory evidence of B. anthracis by one supportive laboratory test or 2) a clinically compatible case of an- thrax epidemiologically linked to a confirmed environmental exposure, but without cor- roborative laboratory evidence of B. -

This work was abruptly arrested by the war, and the fresh start necessary on the liberation of the country emphasized that much health work still remains to be done. A realistic approach to certain disease-problems and the necessity for compe- tent outside assistance to tackle such problems form the basis for future work. The accomplishments of the Ethiopian Government in the limited time since the war bode well for the future. -

Scarlet Fever Fact Sheet
Scarlet Fever Fact Sheet Scarlet fever is a rash illness caused by a bacterium called Group A Streptococcus (GAS) The disease most commonly occurs with GAS pharyngitis (“strep throat”) [See also Strep Throat fact sheet]. Scarlet fever can occur at any age, but it is most frequent among school-aged children. Symptoms usually start 1 to 5 days after exposure and include: . Sandpaper-like rash, most often on the neck, chest, elbows, and on inner surfaces of the thighs . High fever . Sore throat . Red tongue . Tender and swollen neck glands . Sometimes nausea and vomiting Scarlet fever is usually spread from person to person by direct contact The strep bacterium is found in the nose and/or throat of persons with strep throat, and can be spread to the next person through the air with sneezing or coughing. People with scarlet fever can spread the disease to others until 24 hours after treatment. Treatment of scarlet fever is important Persons with scarlet fever can be treated with antibiotics. Treatment is important to prevent serious complications such as rheumatic fever and kidney disease. Infected children should be excluded from child care or school until 24 hours after starting treatment. Scarlet fever and strep throat can be prevented . Cover the mouth when coughing or sneezing. Wash hands after wiping or blowing nose, coughing, and sneezing. Wash hands before preparing food. See your doctor if you or your child have symptoms of scarlet fever.
