BACTERIAL INFECTIONS-IMPETIGO

Definition

Impetigo is a common and highly contagious skin infection that mainly affects infants and children. Impetigo usually appears as red sores on the face, especially around a child's nose and mouth, and on hands and feet. The sores burst and develop honey-colored crusts.

Health Education

Signs and Symptoms

Classic signs and symptoms of impetigo involve red sores that quickly rupture, ooze for a few days and then form a yellowish-brown crust. The sores usually occur around the nose and mouth but can be spread to other areas of the body by fingers, clothing and towels. Itching and soreness are generally mild.

Causes

It's usually caused by one of two bacteria: Staphylococcus aureus or Streptococcus pyogenes (also called group A streptococcus, which also causes strep throat). Methicillin-resistant Staphylococcus aureus (MRSA) is also becoming an important cause of impetigo.

Risk Factors

Age. Impetigo most commonly occurs in children ages 2 to 5.

Crowded conditions. Impetigo spreads easily in schools and child care settings.

Warm, humid weather. Impetigo infections are more common in summer.

Certain sports. Participation in sports that involve skin-to-skin contact, such as football or wrestling, increases your risk of developing impetigo

Broken skin. The bacteria that cause impetigo often enter your skin through a small skin injury, insect bite or rash.

Complications

Cellulitis. This potentially serious infection affects the tissues underlying your skin and eventually may spread to your lymph nodes and bloodstream. Untreated cellulitis can quickly become life-threatening.

Kidney problems. One of the types of bacteria that cause impetigo can also damage your kidneys

Scarring. The ulcers associated with ecthyma can leave scars

Pathophysiology

Gently wash the affected areas with mild soap and running water and then cover lightly with gauze.

Wash an infected person's clothes, linens and towels every day and don't share them with anyone else in your family.

Wear gloves when applying antibiotic ointment and wash your hands thoroughly afterward.

Cut an infected child's nails short to prevent damage from scratching

Wash hands frequently.

Keep your child home until your doctor says he or she isn't contagious.

Classification

Primary Impetigo

Secondary Impetigo

Where the bacteria invades the skin because the barrier has been broken by another infection like scabies or eczema

When the bacteria invades the skin through a cut ,bite or injury

Depending on the clinical presentation it can be Bullous or Non-Bullous

Intact skin is usually resistant to colonization or infection by S aureus or GABHS. These bacteria can be introduced from the environment and only transiently colonize the cutaneous surface. Experimental studies have shown that inoculation of multiple strains of GABHS on to the surface of subjects did not produce cutaneous disease unless skin disruption had occurred.

Medical Mangement

Children < 7 years 12-25mg/kg 6 hourly for 5 days

Children > 7 years and Adults Flucloxacillin 500mg 6 hourly for 5 days and Cephacallin 500mg 6 hourly for 5 days.

Surgical Management

None

Nursing Management

Impetigo is one of the medical conditions listed in the nurse prescribers' extended formulary, which provides guidance on the use of oral antibacterials for the treatment of impetigo. As an independent nurse prescriber, it is important to recognise that the management of impetigo is multifaceted. It is important that the practitioner has an up-to-date clinical and pharmaceutical knowledge, is aware of their limitations, and is also aware of local and national policies in place.
