Two cases of infection of the central nervous system (CNS) with Haemophilus parainfluenzae--a 12-month-old girl with meningitis and a 17-month-old girl with brain abscess--are reported. Both infants had long-standing upper respiratory infection before CNS disease. Both recovered after treatment.

While the bacterial origin of otitis media has been studied extensively in children, there are few data regarding adults with this disease. We undertook this study to identify the incidence, prevalence, and bacteriologic origin of purulent otitis media in adults. This was accomplished through a review of the English-language literature on adult otitis media and a retrospective review of adult patients with this disease who were hospitalized at our institution. Results of literature review indicate that Streptococcus pneumoniae and Haemophilus influenzae are the most common causes of otitis media in ambulatory adults, but this illness is uncommon, with an incidence of only 0.25%. Hospitalized patients in whom this diagnosis was established suffered a variety of serious suppurative complications such as mastoiditis, meningitis, or brain abscess. Otalgia and fever were the most common symptoms noted in this patient population. Further studies of adult otitis media need to be performed to determine bacteriologic, symptomatic, and high-risk patient groups.

The bacteriologic and clinical findings of 39 pediatric patients with intracranial abscess are presented. Twenty-three children presented with brain abscess and 16 with subdural empyema. Predisposing conditions were present in all instances. Sinusitis was present in 25 children and 4 patients each had chronic otitis media, dental abscess, and congenital heart disease. The abscess was located in the frontal area in 14 patients, parietal in 13, and temporal in 12. Anaerobic organisms alone were recovered in 22 patients (56%), aerobic bacteria alone in 7 (18%), and mixed aerobic and anaerobic bacteria in 10 (26%) patients. There were 79 anaerobic isolates (2 per specimen). The predominant anaerobes were anaerobic Gram-positive cocci (29 isolates); Bacteroides sp. (12, including 5 Bacteroides fragilis group), Fusobacterium sp. (14 isolates); and Prevotella sp. and Actinomyces sp. (6 isolates each). A total of 17 aerobic or facultative isolates (0.4 per specimen), including 11 Gram-positive cocci and 6 Haemophilus sp., were recovered. Antimicrobial therapy was administered to all patients. Nine patients (i.e., 6 with sinusitis and subdural empyema, 3 with sinusitis and brain abscess) did not respond to antimicrobial therapy and aspiration of the abscess, and required surgical drainage of inflamed sinuses. These findings indicate the major role of anaerobic organisms in the polymicrobial etiology of intracranial abscess in children.

Fifty-nine patients were operated or punctured in 60 incidents of brain abscess from 1963-1989, twice as many in men as in women. The number of cases tripled in 1980 to an incidence of 3.6 per million inhabitants per year, supposedly due to the advent of computerized tomography. Simultaneously, the aetiology changed from staphylococci and Gram negative rods to dominance of streptococci and Haemophilus aphrophilus. Apart from temporal abscesses, there was no correlation between localisation in the brain and the bacterial species isolated. Ninety-five per cent of the specimens from untreated patients gave growth, but so did specimens from six of 18 patients treated with relevant antibiotics up to 11 days before puncture. Therefore, we recommend removal of pus by excision or puncture.

Thirty children with acute mastoiditis were identified over a 12-year-period and their hospital records were reviewed retrospectively. All had abnormal tympanic membranes and 26 (87%) had swelling above or posterior to the ear that deviated the pinna. Findings on mastoid roentgenograms included clouding (n = 12) and osteitis (n = 7); six were normal. From 13 patients, bacteria were recovered from normally sterile sites and included Pneumococcus (n = 5), group A streptococcus (n = 3), Haemophilus (n = 2), and anaerobes (n = 3). Complications occurred in 13 children, including subperiosteal abscess (n = 7), meningitis (n = 4), osteitis (n = 7), facial palsy (n = 1), and subdural empyema and brain abscess (n = 1). Four of the six children with neurological complications had no external signs of acute mastoiditis on physical examination. Overall, 19 (63%) of the children recovered without mastoidectomy. We conclude that children without meningitis or subperiosteal abscess may be treated initially with antimicrobial therapy plus myringotomy. The need for mastoidectomy should be reassessed in children who fail to respond in 24 to 48 hours.

Anaerobic bacteria form the predominant flora of the oral cavity, outnumbering facultative organisms by 10-1,000: 1. The type of anaerobic bacteria and their concentration depend on the anatomical site and the degree of anaerobiosis in the different sites in the mouth. Three groups of anaerobic bacteria inhabit the oral cavity; the strict anaerobes, the moderate anaerobes, and the microaerophilic group of organisms. The majority of anaerobic bacterial infections occurring in the region of the mouth, head and neck are caused by the commensal flora. These infections include dental and periodontal disease where the predominant organisms are Bacteroides species, Veillonella, Bifidobacteria, Peptococcus, Peptostreptococcus and Propionibacterium species. More recently, Bacteroides endontalis has been isolated from a periapical abscess of endodontal origin and B. gingivalis, B. intermedius, Haemophilus actinomycetemcomitans and Wollinella species in chronic periodontal disease. Treponema species and other strict anaerobes are seen in smears of severe periodontal disease and acute necrotising gingivitis, but have not yet been isolated in pure culture. Until such time, their role in disease remains uncertain. Fusobacterium nucleatum is specially associated with severe orofacial infections which may extend into the mediastinum. Other anaerobic infections include chronic otitis media, chronic sinusitis and mastoiditis, and brain abscess. Treatment of these conditions should include the use of beta-lactamase resistant antimicrobials, such as clindamycin or one of the nitroimidazoles with penicillin.

Chloramphenicol, despite its well-recognized toxic side effects, is a cheap and useful antibiotic in the management of meningitis, typhoid, brain abscess and severe Haemophilus influenza infections. Where possible, drug levels should be monitored.

Imipenem/cilastatin sodium (MK-0787/MK-0791) was evaluated for its safety, efficacy and pharmacokinetics in children. Thirty cases of bacterial infections were treated with MK-0787/MK-0791 at a daily dose of 40 to 222 mg/kg for 2.25 to 13 days. Clinical cure rate was 93% and bacteriological efficacy rate was 88%. Treated diseases included severe tonsillitis due to mixed anaerobic infections, pneumonia, sepsis, brain abscess and soft tissue infections. Two cases, one with periosteomyelitis due to methicillin-resistant S. aureus and the other with pulmonary abscess due to Haemophilus influenzae (other than type b), failed to respond to the MK-0787/MK-0791 therapy. The serum half-life of MK-0787 was 0.892 hour in children with normal renal functions. An episode of convulsions in a case of sepsis with bacterial croup and brain edema was considered to be associated with the MK-0787/MK-0791 therapy. From the present study, MK-0787/MK-0791 appears a safe and effective antibiotic when used in children with a variety of bacterial infections.

A 58-year-old patient developed progressive right hemiparesis and a hemisensory loss. Computed tomography demonstrated a lesion in the left frontoparietal region with ring enhancement. A craniotomy was performed and an abscess was removed, which on culture grew Haemophilus aphrophilus. The same organism was isolated from the patient's poodle dog but not from three other poodles of family members. This, along with previous reports, suggests that the poodle may be a vector in the transmission of this organism, which rarely may cause a brain abscess.
