Raman microspectroscopy was used to characterize and identify the three main pathogens that cause acute otitis media (AOM)in vitro. Cultured middle ear effusion from patients was studied and results suggest the potential of using this technique to aid in accurately diagnosing AOM and providing physicians with bacterial identification to guide treatment.

Acute suppurative otitis media (AOM) is a common, painful condition affecting 20% of children under 4 years at least once a year,1 and perhaps more in infancy when clinical examination is most difficult. Infectious complications such as mastoiditis, meningitis and cerebral abscess are now rare, but chronic middle ear effusion and hearing loss remain common. Hearing loss may persist long after the infective episode,2 and may impair learning.

ABSTRACT Tympanostomy tube (TT) insertion for ventilation of the middle ear is one of most commonly performed procedures in the United States. Indications for tube insertion include otitis media with effusion, recurrent acute otitis media, hearing loss caused by middle ear effusion and persistent acute otitis media. In general, TTs are divided into two categories, short-term tubes and long-term tubes. Depending on the indications for tube placement and surgeon experience with the TT, different tubes can be used. A myriad of tubes have been created since their first documented use in 1845 in attempts to provide better middle ear ventilation, improve ease of placement and prevent complications, such as post-tube otorrhea, persistent perforation and tube occlusion. In order for a tube to be effective, it should be biocompatible with the middle ear to minimize a foreign body reaction. Teflon and silicone remain two of the most commonly used materials in TTs. In addition, the tube design also plays a role for insertion and retention times of TTs. Lastly, TTs can also be coated with various substances, such as silver-oxide, phosphorylcholine and more recently, antibiotics and albumin, in order to prevent biofilm formation and decrease the rate of post-TT otorrhea. Persistent middle ear effusion affects many children each year and can impact their quality of life as well as hearing and language development. With nearly 1 out of every 15 children by the age of 3 years receiving TTs, it is imperative that the right tube be chosen to facilitate optimal ventilation of the middle ear while minimizing complications.

Ear Effusion

Otitis media developed in 67% of chinchillas inoculated intranasally with type 7 Streptococcus pneumoniae and influenza A virus. Only 4% of chinchillas inoculated with influenza alone and 21% of chinchillas inoculated with S. pneumoniae alone developed otitis media. Among the chinchillas that developed otitis media after inoculation with both pneumococcus and influenza, 73% of the affected ears contained effusion, and 27% of the affected ears showed tympanic membrane inflammation without middle ear effusion obtained on paracentesis. Although a majority of the ears with effusion yielded S. pneumoniae on culture, one-third of the effusions were sterile for aerobic bacteria. This model resembles conditions accompanying otitis media in humans and suggests that respiratory viral infection contributes significantly to the pathogenesis of acute otitis media.

A total of 150 children with acute otitis media were randomly allocated to treatment with amoxicillin-potassium clavulanate (Augmentin) or with cefaclor. Each drug was given in a daily dosage of approximately 40 mg/kg in three divided doses for ten days. Tympanocentesis done before treatment yielded specimens that contained pneumococcus or Haemophilus sp or both in 67% of specimens. Viridans group streptococci were isolated from 10% of specimens and Branhamella catarrhalis from 6%. Patients were scheduled for followup examinations at midtreatment, end of therapy, and at 30, 60, and 90 days. Of the 150 children, 130 were evaluable. Five of 60 patients (8%) treated with cefaclor were considered therapeutic failures because of persistent purulent drainage and isolation of the original pathogen or suprainfection. There were no failures among patients treated with Augmentin (P = .019). Rates of relapse, recurrent acute otitis media with effusion, and persistent middle ear effusion were comparable in the two groups of patients. Diaper rash, or loose stools, or both were significantly more common in children treated with Augmentin (34%) than in those taking cefaclor (12%), but in no case was it necessary to discontinue medication because of these mild side effects (P = .002). Cefaclor therapy was discontinued in one patient because of severe abdominal pain and vomiting. In this study, treatment with Augmentin was superior to treatment with cefaclor in the acute phase of acute otitis media with effusion, but Augmentin produced more adverse effects. The rates of persistent middle ear effusion and recurrent acute otitis media with effusion were comparable with the two regimens.
