IMPETIGO BULLEUX PDF

Bullous impetigo on the arm Bullous impetigo Bullous impetigo can appear around the diaper region, axilla , or neck. The bacteria causes a toxin to be produced that reduces cell-to-cell stickiness adhesion , causing for the top layer of skin epidermis , and lower layer of skin dermis to separate. Vesicles rapidly enlarge and form the bullae which is a blister more than 5mm across. Bullae is also known as Staphylococcal scalded skin syndrome.

These usually have to be used for around a week. Read about treating impetigo. Most people are no longer contagious after 48 hours of treatment or once their sores have dried and healed. Ensure any condition that causes broken skin, such as eczema, is treated promptly. If you develop impetigo frequently, your doctor may suggest taking a swab from around your nose to see if you carry staphylococcal bacteria. These bacteria can live in the noses of some people without causing problems, although they can lead to impetigo if they infect broken skin nearby.

Complications of impetigo Complications of impetigo are rare, but they can sometimes occur and can be serious. This means that people can easily pass the infection on to others without realising it. There are two main types of impetigo, known as non-bullous and bullous impetigo, which have different symptoms. Most people with impetigo have the non-bullous type. Non-bullous impetigo The symptoms of non-bullous impetigo begin with the appearance of red sores — usually around the nose and mouth but other areas of the face and the limbs can also be affected.

The sores quickly burst leaving behind thick, golden crusts typically around 2cm across. The appearance of these crusts is sometimes likened to cornflakes stuck to the skin.

After the crusts dry, they leave a red mark that usually heals without scarring. The time it takes for the redness to disappear can vary between a few days and a few weeks.

The sores are not painful, but they may be itchy. It is important not to touch, or scratch, the sores because this can spread the infection to other parts of your body, and to other people. Other symptoms, such as a high temperature fever and swollen glands , are rare but can occur in more severe cases. Bullous impetigo The symptoms of bullous impetigo begin with the appearance of fluid-filled blisters bullae which usually occur on the trunk the central part of the body between the waist and neck or on the arms and legs.

The blisters are usually about cm across. The blisters may quickly spread, before bursting after several days to leave a yellow crust that usually heals without leaving any scarring. The blisters may be painful and the area of skin surrounding them may be itchy. As with non-bullous impetigo, it is important that you do not touch or scratch the affected areas of the skin. Symptoms of fever and swollen glands are more common in cases of bullous impetigo. When to seek medical advice Most cases of impetigo will heal within two or three weeks without treatment, but you should still see your GP if you think you or your child may have the condition.

This is because the symptoms can be similar to more serious skin conditions and treatment can resolve the condition more quickly, as well as reduce the chances of the infection being spread to others. Your GP will normally be able to diagnose impetigo by carrying out a simple examination of your skin. Causes of impetigo Impetigo occurs when the skin becomes infected with bacteria, usually either Staphylococcus aureus or Streptococcus pyogenes. As the condition does not cause any symptoms until four to 10 days after initial exposure to the bacteria, it is often easily spread to others unintentionally.

Impetigo stops being infectious after 48 hours of treatment starting or after the sores have stopped blistering or crusting. Increased risk In addition to the situations mentioned above, there are a number of other factors that can increase your chances of developing impetigo. Treatment is often recommended as it can help clear up the infection in around seven to 10 days and reduce the risk of the infection being passed on to others.

If impetigo is confirmed, it can usually be effectively treated with antibiotics. If the infection is being caused by an underlying skin condition, such as eczema , this may also need to be treated. Antibiotic cream For mild cases of impetigo that cover a small area, antibiotic cream is often recommended.

This usually needs to be applied three or four times a day for seven days. These usually need to be taken two to four times a day for seven days. Common side effects of oral antibiotics include: feeling sick.
