purulent acute otitis media

Purulent Acute Otitis Media (AOM) Description

Purulent acute otitis media, also known as suppurative otitis media, is a type of ear infection characterized by the presence of pus in the middle ear. This condition typically occurs suddenly and can cause severe symptoms.

• Ear Pain: The most common symptom of purulent AOM is severe deep ear pain that can be accompanied by fever.
• Conductive Hearing Loss: Purulent AOM can lead to a conductive hearing loss in the affected ear, making it difficult for individuals to hear sounds clearly.
• Middle Ear Inflammation: The condition is marked by inflammation of the middle ear, which can cause the eardrum to become red and swollen.
• Pus Build-up: As the name suggests, purulent AOM involves the accumulation of pus in the middle ear space.

According to [9], purulent suppurative otitis media is distinguished from secretory (serous) otitis media by the presence of purulent fluid in the middle ear. This condition requires prompt medical attention to prevent complications and ensure proper treatment.

Common Signs and Symptoms of Purulent Acute Otitis Media

Purulent acute otitis media, a type of ear infection, can manifest in various ways. The following are some common signs and symptoms:

• Earache: A sharp, stabbing pain or dull ache in the affected ear is often the first symptom.
• Hearing Loss: Slight hearing loss may occur due to fluid buildup behind the eardrum.
• Fever: A high temperature (fever) can accompany the infection.
• Being Sick: Vomiting or feeling nauseous may be experienced by some individuals.
• Lack of Energy: Feeling tired, irritable, or cranky is common in children and adults alike.
• Purulent Conjunctivitis: Inflammation of the conjunctiva (the thin membrane covering the white part of the eye) can occur.

Additional Symptoms

Some people may experience additional symptoms, including:

• Ear Discharge: A yellow or greenish discharge from the ear canal may be present.
• Swollen Lymph Nodes: Swelling in the neck or behind the ears due to infected lymph nodes.
• Generalized Illness: Feeling unwell, with symptoms like headache, fatigue, and muscle aches.

Important Note

It's essential to seek medical attention if you suspect an ear infection. A healthcare professional can provide an accurate diagnosis and recommend appropriate treatment.

Diagnostic Tests for Purulent Acute Otitis Media

Purulent acute otitis media (AOM) can be diagnosed through various tests, which are essential in confirming the presence of an infection and ruling out other conditions. Here are some diagnostic tests used to diagnose purulent AOM:

• Otoscopy: This is a non-invasive test where a healthcare provider uses an otoscope to examine the ear canal and eardrum. If otitis media is present, pus may be visible in the middle ear (cited from [8]).
• Tympanometry: This test measures how the eardrum responds to a change of air pressure inside the ear. It can help diagnose middle ear effusion and inflammation (cited from [14]).
• Hearing tests: These tests are recommended for children who have had fluid in one or both ears (otitis media with effusion) for a total of 3 months. The tests may be done sooner if hearing loss is suspected (cited from [14]).
• Tympanocentesis: This test involves inserting a small needle into the middle ear to collect a sample of fluid, which can then be sent for bacterial culture and sensitivity testing.
• Imaging studies: While not typically required for uncomplicated AOM, imaging studies such as contrast-enhanced computed tomography (CT) of the temporal bones may be necessary in cases where complications are suspected (cited from [6]).

Diagnostic Criteria

The diagnostic criteria for acute otitis media include:

• Rapid onset of symptoms
• Middle ear effusion
• Signs and symptoms of middle ear inflammation (cited from [5])
• Presence of purulent material in the middle ear (cited from [11])

These tests can help healthcare providers diagnose purulent AOM and develop an effective treatment plan.

Treatment Options for Purulent Acute Otitis Media

Purulent acute otitis media (AOM) requires prompt and effective treatment to alleviate symptoms, prevent complications, and promote healing. The primary goal of treatment is to eliminate the underlying bacterial infection.

• Antibiotics: Antibiotics are the cornerstone of treatment for AOM. According to various studies [1][2][3], high-dose amoxicillin (80-90 mg/kg/day, divided into two daily doses for 10 days) is recommended as first-line antibiotic therapy.
• Alternative Antibiotic Options:
  • Ceftriaxone: 1-2 g IV once daily for three or more days [4]
  • Levofloxacin: 500-750 mg orally once daily for 5-10 days [7]
  • Amoxicillin remains the clear drug of choice, with ten days of therapy being appropriate for children <2 years of age and older children treated for five days [6]

Key Considerations

• Antibiotics should be prescribed when a decision to treat with antibiotics has been made, and the child's condition warrants it [8]
• Most (80%) cases resolve spontaneously; however, antibiotics are often given in the United States [9]

It is essential to note that treatment decisions should be based on individual patient factors, such as age, severity of symptoms, and potential allergies. Consultation with a healthcare professional is recommended for personalized guidance.

The differential diagnosis of purulent acute otitis media (AOM) includes several conditions that can present with similar symptoms, making it essential to accurately diagnose and treat the underlying condition.

Conditions to Consider:

• Otitis externa: An infection of the outer ear canal, which can cause pain, redness, and swelling.
• Eustachian tube dysfunction: A condition where the Eustachian tube, responsible for regulating air pressure in the middle ear, is not functioning properly, leading to fluid accumulation and discomfort.
• Mastoiditis: An infection of the mastoid bone, which can cause pain, fever, and swelling behind the ear.
• Referred pain: Pain from other conditions such as pharyngitis, sinusitis, or toothache that may be referred to the ear.

Key Diagnostic Features:

• Middle ear effusion: The presence of fluid in the middle ear is a sine qua non for diagnosing AOM. A red tympanic membrane is not enough; middle ear effusion must be present.
• Purulent discharge: The presence of pus or purulent discharge from the ear canal can indicate an infection.

Guidelines and Recommendations:

• According to the American Academy of Pediatrics (AAP) guidelines, a diagnosis of AOM requires the presence of acute onset, middle ear effusion, physical evidence of middle ear inflammation, and symptoms such as fever, ear pain, or irritability [6].
• The differential diagnosis of purulent AOM also includes serous/mucous tympanic effusion, which can be distinguished from AOM by the absence of signs of infection [8].

Preventive Measures:

• Long-term antibiotic prophylaxis may be considered for children with recurrent AOM to prevent future episodes [13].
• Efficient preventive measures include proper hygiene, avoiding exposure to allergens and irritants, and addressing underlying conditions that may contribute to AOM.
