Acute Paronychia

Acute paronychia is a type of skin infection that affects the nail folds, which are the soft tissues surrounding the nails. It is a common condition and is usually caused by bacteria such as Staphylococcus aureus or Streptococcus pyogenes. The infection can also be caused by a fungal infection, although this is less common. The term “acute” refers to the sudden and severe onset of symptoms, which typically occur within a few days of the initial infection.

Causes

Acute paronychia is a common condition that affects the nail folds, the skin surrounding the nail plate. It is characterized by inflammation and swelling of the skin and can be caused by various factors. In this article, we will discuss the main causes of acute paronychia.

1. Bacterial Infection

One of the most common causes of acute paronychia is a bacterial infection. Bacteria such as Staphylococcus aureus and Streptococcus pyogenes are often responsible for the condition. These bacteria are commonly found on the skin and can enter the nail fold through cuts or cracks in the skin, causing an infection. The infection can spread rapidly, leading to redness, pain, and swelling of the affected area.

2. Fungal Infection

Another cause of acute paronychia is a fungal infection. Fungi such as Candida albicans can cause an infection in the nail fold. This type of infection is more common in people with weakened immune systems and can be spread through contaminated nail clippers or other objects. The symptoms of a fungal infection include redness, itching, and discharge from the affected area.

3. Trauma

Trauma to the nail fold can also cause acute paronychia. This can occur from biting the nails, frequently picking at the skin around the nails, or from frequent exposure to water and chemicals. The constant exposure to water and chemicals can cause the skin to become dry and irritated, making it more susceptible to infection.

4. Allergic Reactions

Allergic reactions to certain substances can also cause acute paronychia. This can occur from the use of certain cosmetic products, such as nail polish or artificial nails, or from exposure to chemicals found in cleaning products. The symptoms of an allergic reaction can include itching, redness, and swelling of the affected area.

5. Diabetes

People with diabetes are more susceptible to developing acute paronychia. This is because diabetes can cause changes in the skin, making it more prone to infection. Additionally, people with diabetes may have difficulty healing from infections and may experience more severe symptoms.

6. Autoimmune Disorders

Autoimmune disorders such as rheumatoid arthritis and psoriasis can also cause acute paronychia. These conditions can cause changes in the skin, making it more susceptible to infection. Additionally, people with autoimmune disorders may have difficulty healing from infections and may experience more severe symptoms.

Symptoms

The signs and symptoms of acute paronychia can vary, but the most common ones include:

1. Swelling and redness – The infected area may become swollen, red, and tender, causing discomfort and pain. This is due to an accumulation of fluid, called an abscess, that forms as a result of the infection.
2. Pain – Pain is a common symptom of acute paronychia, and it may become more severe when the infected area is touched or when pressure is applied to it.
3. Drainage – In severe cases of acute paronychia, the abscess may break open and drain pus, which is a thick, yellow or greenish fluid that contains dead white blood cells and bacteria.
4. Warmth – The infected area may feel warm to the touch, which is a sign that the body is trying to fight off the infection.
5. Nail changes – The infected nail may become discolored, brittle, or even separate from the nail bed.
6. Difficulty moving the affected finger – In severe cases of acute paronychia, the swelling and pain may make it difficult to move the affected finger.
7. Fever – In some cases, acute paronychia may cause a low-grade fever, which is a sign that the body is fighting off the infection.
8. Lymph node swelling – The lymph nodes may become swollen and tender in response to the infection, indicating that the body is trying to fight off the bacteria or fungus that is causing the infection.

The signs and symptoms of acute paronychia can range from mild to severe, and they may develop quickly or slowly, depending on the cause and severity of the infection. If left untreated, acute paronychia can become a chronic condition and lead to permanent damage to the skin and nails.

Diagnosis

Diagnosis of Acute Paronychia

The diagnosis of acute paronychia is usually made based on the patient’s symptoms and physical examination. A healthcare provider will look for signs of redness, swelling, and pain around the nail fold, as well as any discharge or drainage from the infected area. In some cases, a healthcare provider may also perform a culture of the fluid from the infected area to determine the type of bacteria causing the infection.

Tests for Acute Paronychia

There are several tests that can be used to confirm the diagnosis of acute paronychia and determine the cause of the infection. These tests may include:

1. Physical examination: This is the most common diagnostic test for acute paronychia. A healthcare provider will examine the affected area for signs of redness, swelling, pain, and discharge or drainage.
2. Culture: A sample of the fluid from the infected area can be taken and cultured to determine the type of bacteria causing the infection. This test is usually done if the infection is not responding to treatment or if the healthcare provider suspects that the infection is caused by a specific type of bacteria.
3. Blood tests: Blood tests may be ordered if the healthcare provider suspects that the patient has a systemic illness that is contributing to the development of acute paronychia. This may include tests for diabetes, autoimmune disorders, or other conditions that can weaken the immune system.
4. Skin Culture: A skin culture is a test that involves taking a sample of the affected skin and growing it in a laboratory. This test helps to identify the type of bacteria or fungus causing the infection.
5. X-rays: X-rays may be ordered if the healthcare provider suspects that the infection has spread to the underlying bone. This test can also help to determine if there is any bone damage or other underlying conditions that may be contributing to the development of acute paronychia.

Treatment

The first line of treatment for acute paronychia is typically antibiotics. Antibiotics are used to control the growth of bacteria that cause the infection and to reduce the risk of spread to other parts of the body. The type of antibiotic used will depend on the type of bacteria that is causing the infection. Common antibiotics used to treat acute paronychia include penicillin, amoxicillin, clavulanic acid, and cephalosporins.

Antibiotics:

Antibiotics are often used to treat acute paronychia caused by bacterial infections. The most commonly used antibiotics for this condition are penicillin, amoxicillin, and cephalosporins. These drugs work by killing the bacteria that are causing the infection. The type of antibiotic used will depend on the type of bacteria that is causing the infection, as well as the severity of the infection.

Antifungal Medications:

Antifungal medications are used to treat acute paronychia caused by fungal infections. The most commonly used antifungal medications for this condition are terbinafine, itraconazole, and fluconazole. These drugs work by killing the fungus that is causing the infection. The type of antifungal medication used will depend on the type of fungus that is causing the infection, as well as the severity of the infection.

Anti-inflammatory Drugs:

Anti-inflammatory drugs are used to treat acute paronychia to reduce swelling, pain, and redness in the affected area. The most commonly used anti-inflammatory drugs for this condition are ibuprofen, aspirin, and naproxen. These drugs work by reducing the production of prostaglandins, which are chemicals that cause inflammation.

In addition to these drugs, there are several other treatments that can be used to treat acute paronychia. These include:

Warm Soaks:

Warm soaks can help to reduce swelling and pain in the affected area. To do this, fill a basin with warm water and soak the affected finger for 10-15 minutes, several times a day. This will help to soften the skin and make it easier to drain any pus that may be present.

Drainage:

If there is a lot of pus present in the affected area, it may need to be drained. This can be done by making a small incision in the skin over the infected area and allowing the pus to drain out. This should only be done by a healthcare professional.

Topical Treatments:

Topical treatments, such as creams or ointments, can be applied directly to the affected area to help reduce inflammation and promote healing. These treatments may contain antibiotics, antifungal medications, or other active ingredients that can help to reduce the severity of the infection.

In severe cases of acute paronychia, a physician may prescribe a combination of antibiotics, such as amoxicillin and clavulanic acid, to increase the effectiveness of treatment. Antibiotics are usually taken orally in the form of pills or capsules, and the duration of treatment will depend on the severity of the infection. It is important to take antibiotics as directed by a physician and to finish the full course of treatment, even if symptoms improve before the end of treatment, to prevent the development of antibiotic-resistant bacteria.

In addition to antibiotics, pain relief medication may also be prescribed to manage pain and swelling in the affected area. Over-the-counter pain relievers such as ibuprofen and acetaminophen can be used, or a prescription pain medication may be prescribed if the pain is severe. Topical pain relief medications, such as creams or ointments, may also be used to provide localized pain relief.

Soaking the affected area in warm water can also help to reduce pain and swelling. This can be done several times a day and should be continued until the infection has cleared up. It is important to avoid using hot water, as this can increase the risk of spreading the infection.

In some cases, surgical intervention may be necessary to treat acute paronychia. This may involve the removal of the affected part of the nail or the drainage of pus from the infected area. In severe cases, a portion of the nail may need to be removed to prevent the spread of infection to other parts of the body.

Surgical treatments for acute paronychia are typically reserved for cases that are not responding to medical treatment or for cases that have progressed to an abscess. The surgical intervention may involve draining the abscess, debriding the infected tissue, or removing the infected nail.

Draining the abscess involves making a small incision in the affected area to allow the infection to drain out. This procedure is usually performed under local anesthesia and can be done in an outpatient setting. Debridement involves removing the infected tissue to help control the infection and prevent further spread. This procedure may be performed in conjunction with draining the abscess or as a separate procedure.

Removing the infected nail is typically a last resort and is reserved for severe cases of acute paronychia that are not responding to other forms of treatment. This procedure involves removing the entire nail and the surrounding tissue to help control the infection and prevent further spread. This procedure is usually performed under local anesthesia and may be done in an outpatient setting or as an inpatient procedure.

In addition to medical and surgical treatments, there are several steps that patients can take to help control the infection and prevent further spread. These steps include:

1. Keeping the affected area clean and dry. This can be done by washing the affected area with soap and water and applying an antiseptic.
2. Avoiding trauma to the affected area. This can be done by wearing gloves when working with your hands, avoiding aggressive nail biting or picking, and avoiding contact with irritants or allergens.
3. Taking pain medications as prescribed. This can help to manage the pain and discomfort associated with acute paronychia.
4. Avoiding exposure to water. This can help to prevent further spread of the infection.
5. Following up with your healthcare provider. Regular follow-up appointments are important to monitor the progress of the infection and to adjust the treatment plan as necessary.

In addition to medical treatment, there are also a number of self-care measures that can be taken to promote healing and prevent the spread of infection. It is important to keep the affected area clean and dry, and to avoid using harsh soaps or detergents that can further irritate the skin.

Wearing gloves when engaging in manual labor or exposure to water can also help to prevent the development of acute paronychia. Keeping the nails trimmed and avoiding biting or picking at the nails can also help to reduce the risk of infection.
