Ear wax and otitis media in children.

A study was designed to find the prevalence of ear wax in children aged 3 to 10 years and to test the belief that large amounts of wax are unlikely to be seen when otitis media is present. Roughly a quarter of the children had appreciable amounts of wax, and there was a gradual decline in prevalence with age. The amount of ear wax appeared to decrease when otitis media was present. The results did not support removing wax when assessing children''s ears in general practice.     

Etiology and treatment of pneumonia in children]

The most widespread pathogens of pneumonia in children i.e. Streptococcus pneumoniae and Haemophilus influenzae and their antibiotic susceptibility are described. The ways of selecting starting antibacterial drugs for the treatment of community-acquired and hospital pneumonia are recommended proceeding from the original findings and some literature data. Oral drugs for the treatment of uncomplicated pneumonia are shown to be preferential. In the treatment of nosocomial or hospital pneumonia the starting regimen should allow for the previous antibacterial therapy.     

Olfactory function in Australian aboriginal children and chronic otitis media

Chronic suppurative otitis media (CSOM), a severe form of middle ear infection, affects most Australian Aboriginal children with up to 50% in some communities suffering hearing loss as a consequence. To date, there is no information on whether repeated exposure to the pathogens that characterize CSOM and that are present in the upper respiratory airway affect olfactory function. Accordingly, this study aimed to determine whether 1) there was a high prevalence of olfactory loss in Aboriginal children and 2) hearing loss is a predictor of olfactory loss. Two hundred and sixty one 9- to 12-year-old Aboriginal children from 16 rural communities reported to have high prevalences of CSOM and hearing loss were assessed for olfactory loss using a 16-odor identification test and hearing loss. One child was found to be anosmic, 4 were slightly hyposmic, and 42 had hearing loss. No relationship was found between olfactory loss and hearing loss. The test-retest reliability of the 16-odor identification test was 0.98. It was concluded that CSOM does not appear to affect olfactory function in the long term and that hearing loss in Aboriginal children is not a predictor of olfactory loss.     

Chronic granulomatous otitis media in bottle-fed Inuit children.

Otitis media in Inuit children is a problem of relatively recent origin and unknown cause. The prevalence of otitis media in 238 Inuit and 47 Caucasian children in Nain, a small community in Labrador, was determined by examination, and the history of breast-feeding or bottle-feeding was obtained. The prevalence of otitis media was found to be inversely related to the age at which bottle-feeding was started. Clinical observations suggest that otitis media in Inuit children is part of a process leading to chronic foreign body granuloma of the middle ear, and that the granuloma is formed from milk introduced into the relatively short and straight eustachian tubes of Inuit infants by the high negative intraoral pressure necessary for bottle-feeding.     

The role of anaerobic bacteria in chronic suppurative otitis media in children: Implications for medical therapy

This review describes the microbiology, diagnosis and medical management of chronic suppurative otitis media (CSOM) in children highlighting the role of anaerobic bacteria. In studies that employed adequate method for recovery of anaerobic bacteria polymicrobial aerobic and anaerobic flora was isolated from over half of the children with CSOM. The predominant aerobic isolates were Staphylococcus aureus and Pseudomonas aeruginosa and the most frequently isolated anaerobic organisms were Peptostreptococcus, Fusobacterium spp. and pigmented Prevotella and Porphyromonas spp. Several studies illustrated the efficacy of anti-infective agents effective against anaerobic bacteria in the treatment of CSOM. The medical therapy of CSOM should be directed at the eradication of the pathogenic aerobic and anaerobic organisms.     

Etiology of acute suppurative destructive pneumonias in children]

Clinical, immunological and bacteriological studies were carried out in 63 children with the so-called staphylococcus destruction of the lungs. It was shown that in some of the cases destructive process in the lungs, along with the pathogenic staphylococcus, could be caused by the Gram negative bacteria (Proteus, Bac. pyocyaneus, etc.). It was found that in children of different age groups the titre of antistaphylococcus antibodies up to 0.5 AU/ml was normal and pointed to the absence of any inflammatory disease of staphylococcus etiology; a titre of 2 AU/ml - and overcould be considered as diagnostic. In connection with bacterial poly-etiology of acute destruction of the lungs in children it is suggested that it should be designated as "acute purulent destructive pneumonia". The importance of immuno-bacteriological studies in children with diseases with the mentioned pathology is emphasized; these examinations permit to choose proper complex therapy.     

Characterization of Streptococcus pneumoniae isolated from children with otitis media

Streptococcus pneumoniae is the main causative agent of acute otitis media in children. Serotype-based vaccines have provided some protection against otitis media, but not as much as anticipated, demonstrating the need for alternative vaccine options. Pneumococcal otitis media isolates were obtained from children 5 years old or younger from hospitals around Mississippi in the prevaccine era (1999-2000). These isolates were compared by capsular typing, pneumococcal surface protein A (PspA) family typing, antibiotic susceptibility, and DNA fingerprinting. Our study shows that there is great genetic variability among pneumococcal clinical isolates of otitis media, except with regard to PspA. Therefore, efforts focused on the development of a PspA-based pneumococcal vaccine would be well placed.
