Study Notes

Disease Summary

Acute otitis media (AOM) is inflammation of the middle ear, characterized by a painful infection with rapid symptom onset.
Most AOM cases occur in children, often following viral upper respiratory infections, leading to fluid accumulation that predisposes to bacterial infection.
Symptoms include earache (otalgia), pressure in the ear, hearing loss, and fever.

Prevalence

AOM is most prevalent in infants and children, with 80-90% of cases occurring before age 6.
Peak incidence is between 6-18 months, with a second peak at ages 4-5 as children enter school.
AOM accounts for about 20 million physician visits annually and is the leading cause of febrile illness diagnoses in children.
Approximately half of children experience AOM by their first birthday, and one-third of those over 7 have had at least six episodes.

Significance

AOM is extremely painful, particularly in the first 24 hours; pain assessment in nonverbal children can be challenging.
Mortality rate is low at 1 death per 100,000 cases, but morbidity remains significant, with potential complications like mastoiditis and chronic otitis media leading to permanent hearing loss.

Causes and Risk Factors

Common bacteria responsible for AOM include:
- Streptococcus pneumoniae
- Haemophilus influenzae
- Moraxella catarrhalis
Viruses linked to AOM include respiratory syncytial virus and various influenza strains.
Children face greater susceptibility due to narrower eustachian tubes and immature immune systems.
Higher risk factors include:
- Attendance at large childcare centers
- Genetic predisposition
- Changes in altitude or cold climates
- Lower socioeconomic status, leading to factors like exposure to cigarette smoke and crowded living conditions.

Diagnosis: Clinical Manifestations and Lab Tests

Suspect AOM in children with symptoms like otalgia, otorrhea, upper respiratory infection signs, lethargy, irritability, or gastrointestinal issues.
Young children may tug at their ears as a sign of pain, with increased symptoms when lying down.
Advanced symptoms can include hearing loss, tinnitus, vertigo, and unsteadiness.
Physical examination reveals a pale gray, translucent tympanic membrane (TM) in normal conditions, while a bulging TM is a key sign of fluid presence in AOM.
Redness of the TM alone does not confirm AOM; eardrum mobility and position (bulging or retracted) are crucial for diagnosis.

Complications

Mastoiditis can occur if the infection spreads, indicated by lateral ear displacement and tenderness in the postauricular area.
TM perforation is a common complication but usually heals without residual effects within 2 weeks.

Treatment Considerations

Antibiotics can cause side effects including nausea, diarrhea, and allergic reactions; frequent use may lead to antibiotic resistance.
Over-the-counter pain relievers like ibuprofen or acetaminophen are effective for managing otalgia.
