Signs and symptoms
Symptoms of toxic shock syndrome (TSS) vary depending on the underlying cause. TSS resulting from infection with the bacterium Staphylococcus aureus typically manifests in otherwise healthy individuals via signs and symptoms including high fever, accompanied by low blood pressure, malaise and confusion, which can rapidly progress to stupor, coma, and multiple organ failure. The characteristic rash, often seen early in the course of illness, resembles a sunburn (conversely, streptococcal TSS will rarely involve a sunburn-like rash), and can involve any region of the body including the lips, mouth, eyes, palms and soles of the feet. In patients who survive, the rash desquamates (peels off) after 10–21 days.STSS caused by the bacterium Streptococcus pyogenes, or TSLS, typically presents in people with pre-existing skin infections with the bacteria. These individuals often experience severe pain at the site of the skin infection, followed by rapid progression of symptoms as described above for TSS. Pathophysiology
In both TSS (caused by S. aureus) and TSLS (caused by S. pyogenes), disease progression stems from a superantigen toxin. The toxin in S. aureus infections is TSS Toxin-1, or TSST-1. The TSST-1 is secreted as a single polypeptide chain. The gene encoding toxic shock syndrome toxin is carried by a mobile genetic element of S. aureus in the SaPI family of pathogenicity islands. The toxin causes the non-specific binding of MHC II, on professional antigen presenting cells, with T-cell receptors, on T cells.
Nonetheless, the value of distinguishing this type of insomnia from other types is debatable due to the relatively low frequency of SSM being reported.Sleep state misperception can also be further broken down into several types, by patients who:

report short sleep (subjective insomnia complaint without objective findings)or no sleep at all (subjective total insomnia)
report excessive daytime sleepiness (subjective sleepiness complaint without objective findings)
report sleeping too much (subjective hypersomnia without objective findings)

Validity
The validity and reliability of the sleep state misperception as a pertinent medical entity was questioned. A study found poor empirical support for this diagnostic item. Symptoms and diagnosis
This sleep disorder frequently applies when patients report not feeling tired despite their subjective perception of not having slept. Generally, they may describe experiencing several years of no sleep, short sleep, or non-restorative sleep. Otherwise, patients appear healthy, both psychiatrically and medically. (That this condition is often asymptomatic could explain why it is relatively unreported.) However, upon clinical observation, it is found that patients may severely overestimate the time they took to fall asleep—often reporting having slept half the amount of time indicated by polysomnogram or electroencephalography (EEG), which may record normal sleep. Observing such discrepancy between subjective and objective reports, clinicians may conclude that the perception of poor sleep is primarily illusionary. Alternatively, some people may report excessive daytime sleepiness or chronic disabling sleepiness, while no sleep disorder has been found to exist.
