ABSTRACT Recurrent acute otitis media (rAOM) is frequently encountered in infants and children and the lack of any definitive treatment has led parents and physicians to try complementary and alternative therapies. We evaluated the efficacy of a propolis and zinc suspension in preventing AOM in 122 children aged 1-5 years with a documented history of rAOM, who were prospectively, blindly, randomized 1:1 to receive the suspension plus elimination of environmental risk factors or elimination of environmental risk factors only. AOM- and respiratory-related morbidity were assessed at study entry and every four weeks. In the 3-month treatment period AOM was diagnosed in 31 (50.8%) children given the propolis and zinc suspension and in 43 (70.5%) controls (p=0.04). The mean number of episodes of AOM per child/month was 0.23+/-0.26 in the propolis and zinc group and 0.34+/-0.29 in controls (reduction 32.0%, p=0.03). The administration of a propolis and zinc suspension to children with a history of rAOM can significantly reduce the risk of new AOM episodes and AOM-related antibiotic courses, with no problem of safety or tolerability, and with a very good degree of parental satisfaction. No effect can be expected on respiratory infections other than AOM.

    ABSTRACT: Background Middle ear infections are common, especially among young children, usually causing earache and some temporary (occasionally permanent) hearing loss. Zinc is an essential micronutrient, which has a role in the optimal functioning of the immune system and resistance to infection. It must be consumed regularly as it cannot be stored in the body. Some people, especially children in low- and middle-income countries, may not have adequate zinc intake from food alone. Researchers have examined the potential role of zinc supplements in preventing infective illnesses. Therefore we wanted to discover whether zinc supplements have any role in preventing middle ear infections. Study characteristics The review authors searched the medical literature for studies up to March 2014. We searched for trials which compared middle ear infections in people randomly selected to receive zinc supplements or who did not receive supplements. We found 10 eligible studies, all conducted amongst young children. The total number of participants was 6820. Nine trials were conducted in low- and middle-income countries. Seven trials were conducted on healthy children. Participants included both males and females. Results The results of the trials provided no convincing evidence that zinc supplements reduce the occurrence of middle ear infections in healthy children. However, in one small study of severely malnourished children, those receiving zinc supplements had fewer middle ear infections. The only adverse effect was vomiting. Quality of evidence The trial evidence included is generally of good quality, with a low risk of bias. All the included trials included otitis media only as a secondary outcome. Therefore, there was a potential to miss trials which were less publicised or less well indexed within the electronic databases.

    ABSTRACT: Background and Objectives Otitis media (OM) is one of the most common reasons for antibiotic treatment in children. Controversies regarding antibiotic treatment for OM have accumulated in the past decade, and there seem to be more dilemmas than certainties. The objectives of this article are to provide the state-of-the art review on achievements in treatment of all different stages of OM, including acute otitis media (AOM), otitis media with effusion (OME), and chronic suppurative otitis media, and to outline the future research areas. Data Sources PubMed, Ovid Medline, the Cochrane Database, and Clinical Evidence (BMJ Publishing). Review Methods All types of articles related to OM treatment published in English between January 2007 and June 2011 were identified. A total of 286 articles related to OM treatment were reviewed by the panel members; 114 relevant quality articles were identified and summarized. Results New evidence emerged on beneficial results of antibiotic treatment, compared with observation of AOM in young children who were diagnosed based on stringent criteria. In OME, the main results were related to a nonsignificant benefit of adenoidectomy versus tympanostomy tube placement alone in the treatment of chronic OME in younger children. Other modalities of OM treatment were studied and described herein. Conclusions and Implications for Practice Significant progress has been made in advancing the knowledge on the treatment of OM. Areas of potential future research have been identified and outlined.
