Folliculitis

 Folliculitis is an inflammation or infection of the hair follicle, a small pocket in the skin where hair grows. It is common on the face, scalp, neck, chest, chest, back, buttocks and thighs, but can occur anywhere on the body where there is hair. It can range from mild inflammation to severe infection.

Causes of folliculitis :

 Folliculitis can be caused by several factors, including  

1. infectious causes:

•  bacteria: most commonly Staphylococcus aureus.
•  Fungi: for example Malassezia and Candida.
•  Viruses: herpes simplex virus can cause folliculitis. 
• Parasites: rare cases caused by mites and other organisms.

2. Non-infectious causes:

• irritation from shaving, waxing, tight clothing.
•  Blockage of hair follicles by sebum, sweat or cosmetics. 
• Friction and heat, common in 'hot bath folliculitis' caused by Pseudomonas aeruginosa.

Symptoms of folliculitis : 

• Small, red or white bumps that look like pimples, often with hair in the center.
•  The pus-filled blisters may crust over. 
• Itching, tenderness or burning sensation.
•  Swelling and pain in the skin around the affected area. 
• In severe cases, large boils or abscesses may form.

 Types of folliculitis

1. Superficial folliculitis:

• Affects only the top part of the hair follicle.
•  It appears as small red bumps or pustules. 

2. Deep folliculitis:

• Affects the entire hair follicle, including the deeper layers of the skin. 
• It can cause painful, larger lesions and abscesses.

 The specific types are:

•  Bacterial folliculitis: Caused by Staphylococcus aureus, it appears as pus-filled bumps. 
• Pseudofolliculitis Barbae: Common in people who shave. It is caused by ingrown hairs that cause irritation and inflammation.
•  Hot tub folliculitis: Associated with Pseudomonas aeruginosa and appears as red, itchy bumps after immersion in a neglected hot tub or swimming pool.
•  Fungal folliculitis: Caused by a fungal infection such as Malassezia.
•  Gram-negative folliculitis: usually develops after long-term antibiotic treatment of acne.

 Diagnosis

 Health professionals usually diagnose folliculitis by looking at its appearance. In more severe or persistent cases.

•  the diagnosis is made by taking a skin sample to identify bacteria, fungi or other organisms. 
• If the cause is unclear, a biopsy is performed to confirm the diagnosis.

 Folliculitis treatment :

Mild cases:

•  warm compresses: reduce inflammation and promote drainage.
•  Gentle cleansing: use antibacterial or antifungal cleansers.

 Topical treatment:

• antibiotic creams such as mupirocin or clindamycin for bacterial infections.
•  Antifungal creams such as ketoconazole for fungal infections. 

Oral:

• Oral antibiotics such as cephalexin for bacterial folliculitis. 
• Oral antifungals such as fluconazole for fungal folliculitis. 

Other treatments: 

• For pseudofolliculitis: stop shaving or use hair removal creams or lasers.
•  For hot tub folliculitis: mild cases usually heal on their own.

 Home remedies and personal care

•  Avoid shaving or irritating the affected area.
•  Use a clean, sharp razor or switch to electric clippers. 
• Wash with antibacterial soap and apply an over-the-counter cream. 
• Avoid tight clothing that rubs the skin.
•  Soothe the skin with bath salts containing aloe vera or oatmeal.

 Complications :

 If left untreated or poorly managed, 

• folliculitis can lead to rash or abscess.
•  Permanent scarring or dark spots (hyperpigmentation).
•  Recurrent infections or chronic folliculitis. 
• Cellulitis, a deeper skin infection.

 Prevention : 

• Maintain hygiene and keep your skin clean.
•  Avoid sharing personal items such as razors and towels.
•  Use non-comedogenic skin care products to prevent clogged pores. 
• Avoid tight clothing, extreme heat and friction. 

If folliculitis persists or worsens despite treatment, consult a health care professional for further evaluation and management.

Cellulite

 Cellulitis is a common bacterial skin infection that affects the deeper layers of the skin and the subcutaneous tissue. When bacteria enters the skin through cuts, wounds or breaks, such as insect bites, it can form and spread quickly if left untreated.

Causes of cellulite

Cellulite is most often caused by 2 types of bacteria:

• Streptococcus pyogenes (Group a Streptococcus)
• In some cases, Staphylococcus aureus, including methicillin-resistant Staphylococcus aureus (MRSA).

These bacteria can enter the skin:

• Cuts, scratches or abrasions
• insect bites and stings
• Surgical wounds
• Ulcers and chronic skin diseases such as eczema and athlete's foot
• Cracked or peeled (for example, from dry skin or fungal infections)

Symptoms of cellulite

The main symptoms of cellulite are::

1. Redness: The affected area appears red and inflamed.
2. Swelling: The area is swollen and difficult to touch.
3. Temperature: The infected area will feel hot or hot.
4. Pain or tenderness: The skin may become soft or painful to the touch.
5. Fever: In more severe cases, there may be chills, fever or fatigue.
6. Pus-filled blisters or abscesses: In some cases, fluid-filled blisters may develop.

The infection usually affects the lower limbs, but it can occur anywhere on the body, including the face, arms, or torso.

Risk factors

Some factors increase the likelihood of developing cellulite:

• Skin damage: cuts, burns or surgical wounds.
• Skin condition: Eczema, athlete's foot or other conditions that compromise the skin barrier.
• Chronic swelling (lymphedema): increases the susceptibility to skin infections.
• Weakened immune system: for diabetes, HIV, cancer or drugs that suppress the immune system.
• Obesity: Increases the risk of cellulite in the lower extremities.
• Previous cellulitis: Past infections are more likely to recur.

Diagnosis:

Cellulite is diagnosed by physical examination. Key symptoms include redness, swelling, and warmth in the affected area. Dec. Healthcare providers can also do the following:

• Check for signs of systemic infection (fever, chills, or lymphadenopathy).
• Order a blood test or wound culture in severe or abnormal cases to identify certain bacteria.
• Use imaging (e.g. ultrasound or MRI) to rule out deeper infections such as abscesses.

Cellulite treatment:

Treatment is aimed at eliminating the infection, reducing symptoms and preventing complications. It typically includes:

1.Antibiotics:

• Oral antibiotics such as cephalexin, amoxicillin clavulanate or clindamycin for mild to moderate cases.
• Intravenous (IV) antibiotics for severe cases, infections that do not respond to oral treatment, or infections caused by resistant bacteria, such as MRSA.

2.Symptom management:

• Pain relief: Over-the-counter painkillers such as acetaminophen and ibuprofen.
• Lifting: Lifting the affected limb to reduce swelling.

3.Wound care:

• Cleans and closes open wounds to prevent further infection.

Complications

If cellulite is left untreated, it can cause serious complications such as:

1. Abscess formation: Pus pockets that may require drainage.
2. Sepsis: A life-threatening condition in which the infection has spread to the bloodstream.
3. Lymphangitis: The infection spreads to the lymphatic system.
4. Chronic swelling (lymphedema): Permanent damage to the lymph vessels can cause chronic swelling.
5. Necrotizing fasciitis (rare): This is a severe, rapidly spreading infection that destroys tissue and requires urgent treatment.

Prevention

To reduce the risk of cellulite:

• It keeps the skin clean and moisturizes: prevents cracking and dryness. Jul.
• Treat wounds quickly: clean cuts, abrasions or insect bites, apply antibiotic ointment.
• Wear protective clothing: in an environment that may cause injury.
• Manage chronic diseases: Manage diabetes and other conditions that damage immunity and skin integrity.
• Prevent fungal infections: Quickly treat athlete's foot or similar conditions.

When to see a doctor

If you have experienced this, seek medical help immediately:

• It quickly aggravates redness and swelling.
• High fever or chills. Severe pain or the appearance of pus-filled blisters.
• Symptoms of systemic infection, such as fatigue and confusion.

Your Prediction

With rapid treatment, most cases of cellulite improve within 7 to 10 days. However, severe or untreated cases can lead to serious complications. Preventive measures and early intervention are important to avoid recurrent infections.

Impetigo

Impetigo is a highly contagious bacterial skin infection that mostly affects babies, but can affect people of all ages. Impetigo is caused by two types of bacteria: staphylococcus aureus (staphylococcus) and Streptococcus pyogenes (streptococcus). It is usually transmitted by scratching a small cut, insect bite or eczema-like rash, but it can also develop on healthy skin.

Types of impetigo:

There are two main types of impetigo

1.Non-bullous infectious impetigo (more common type):

It starts as small red sores or blisters that quickly break and ooze, forming honey-colored crusts. These sores usually appear around the nose and mouth, but can also spread to other parts of the body.

2.Bullous impetigo:

Larger fluid-filled blisters (bullae) that take longer to rupture and leave a yellowish crust. This type is more common in babies and tends to appear on the trunk (abdomen) and around the diaper area.

Symptoms of contagious impetigo:

• Red sores that quickly turn into yellow-brown scabs.

• Itching and discomfort in the affected area.

• In some cases, swelling of the lymph nodes in the infected area.

• Blisters filled with fluid (bullous impetigo).

• Spread of sores to other parts of the body through touching, scratching or close contact with others.

• Direct skin contact with an infected person.

• Contact with contaminated surfaces, towels, clothes and bed linen.

• Touching other parts of the body or other people after scratching or touching sores.

• Young children: especially children aged 2-5 years are more prone to cuts and abrasions.

• Crowded environments: schools, kindergartens and sports fields increase the likelihood of spreading germs.

• Skin damage: cuts, insect bites, eczema and other skin conditions can allow bacteria to enter the skin.

• Hot, humid climates: In these environments, impetigo is more likely to develop through sweating and rubbing against the skin.

• Impetigo contagiosa is usually treated with antibiotics to eliminate the infection and prevent it from spreading. Treatment may include

• Mupirocin (Bactroban) or retapamulin (Altavax) ointment is usually prescribed and applied directly to the affected area.

• For more common or severe cases, oral antibiotics such as cephalexin or dicloxacillin are prescribed.

• Wash affected areas with soap and water and keep clean.

• Avoid scratching or touching the wounds.

• Cover wounds with gauze or loose bandages to prevent the spread of infection.

• Wash your hands often and practice good hygiene, especially with children.

• Wash towels, clothes and bed linen of infected people separately using hot water.

• Avoid sharing towels, razors, clothes and other personal items.

• Cellulitis: deep bacterial infection of the skin and underlying tissues.

• Post-streptococcal glomerulonephritis: A rare condition in which the infection affects the kidneys, causing inflammation and sometimes damage.

• Scarring: In severe cases, impetigo can leave scars.

Causes and transmission:

Infectious impetigo occurs when bacteria invade the skin through wounds or cuts. Impetigo is highly contagious and is spread through the following infection routes

It is more common in warm, humid environments and spreads easily in schools, kindergartens and sports teams.

Risk factors:

Diagnosis:

Impetigo is usually diagnosed by examination by a health professional. Fluid may be taken from wounds to identify the causative organism, especially if the infection is severe or not responding to treatment.

Treatment of impetigo:

Topical antibiotics:

Oral antibiotics:

Home care and prevention

Complications:

Impetigo contagiosa is usually mild and can be improved with treatment, but if left untreated or treated incorrectly it can lead to complications such as

Prognosis:

With prompt treatment, impetigo usually heals within 1-2 weeks and leaves no sequelae. Antibiotics shorten the duration of infection and most people are no longer infected after 24-48 hours of treatment.

If you suspect infectious impetigo or see skin sores that do not heal, it is important to consult a health care professional for proper diagnosis and treatment.
