Scarlet fever usually starts with a sudden fever associated with sore throat, swollen neck glands, headache, nausea, vomiting, loss of appetite, swollen and red strawberry tongue, abdominal pain, body aches, and malaise. The characteristic rash appears 12–48 hours after the start of the fever. The rash usually starts below the ears, neck ...
Fever most commonly indicates bacterial or viral infection. If there is no systemicsepsis, localisedrashes associated with infection tend to cause fewer systemic symptoms than generalised rashes associated with infection. Mucosal involvement is common. There are some acute auto- inflammatory disorders than mimic infection due to neutrophil ...
Scarlet fever is a bacterial illness that often presents with a distinctive rash made up of tiny pinkish-red spots that cover the whole body. It affects people who have recently had a sore throat (strep throat) or school sores ( impetigo ) caused by certain strains of the group A streptococcus bacteria.
Streptococcal perianal and/or vulval dermatitis. Impetigo. Cellulitis. Necrotising fasciitis. In addition, streptococci are capable of causing skin disease through means other than direct infection of the skin; for example: Scarlet fever is a reaction to a circulating toxin that is produced by some strains of streptococcus.
Scarlet fever; Streptococcal toxic shock-like syndrome (STSS). Other specific infections that can give rise to exanthems include: Mycoplasma pneumonia; Rickettsial diseases. Exanthems may also be due to a drug (especially antibiotics and nonsteroidal anti-inflammatory drugs). See: Morbilliform drug eruption; Drug hypersensitivity syndrome.
Introduction. An exanthem is a widespread erythematous rash that is accompanied by systemic symptoms such as fever, headache and malaise. Exanthems during childhood are usually associated with viral infection and represent either a reaction to a toxin produced by the organism, damage to the skin by the organism, or an immune response.
Toxic epidermal necrolysis (T.E.N.) is characterised by fever (>38C), widespread tender erythema affecting >30% skin surface associated with mucosal involvement. Erythema is followed by extensive full thickness cutaneous and mucosal necrosis and denudation within 2 or 3 days. Similar symptoms and signs involving less than 10% of the body ...
Differential diagnosis includes measles, rubella, scarlet fever, non-specific toxic erythema associated with infection, Kawasaki disease, connective tissue disease and acute graft-versus-host disease. Tests are not usually necessary if the cause has been identified and stopped, the rash is mild and the patient is well. They may include:
Infectious mononucleosis is a contagious viral infection usually caused by EBV (human herpesvirus-4, HHV4), a gamma-herpesviridae DNA virus. EBV is implicated in a wide range of human diseases, many of which have mucocutaneousmanifestations that can be acute or chronic.
The blistering of large areas of skin gives the appearance of a burn or scalding, hence the name staphylococcal scalded skin syndrome. SSSS is often used interchangeably with the eponymous name Ritter von Ritterschein disease (Ritter disease), particularly when it presents in newborn children. Superficial blistering over the axillae, face and ...
