Nontypeable Haemophilus influenzae (NTHi) causes acute otitis media (AOM) in infants. Breast-feeding protects against AOM and/or nasopharyngeal (NP) colonization; however, the mechanism of protection is incompletely understood. Children with AOM and healthy children were studied according to feeding status: breastfed,breast/formula fed, or formula fed. Cumulative episodes of AOM, ELISA titers of serum IgG antibodies to whole-cell NTHi and vaccine candidate outer membrane protein P6, bactericidal titers of serum and NP colonization by NTHi were assessed. A lower incidence of AOM was found in breast- versus formula-fed children. Levels of specific serum IgG antibody to NTHi and P6 were highest in breast-fed, intermediate in breast/formula fed, and lowest in formula-fed infants. Serum IgG antibody to P6 correlated with bactericidal activity against NTHi. Among children with AOM, the prevalence of NTHi in the NP was lower in breast- versus nonbreast-fed infants. We conclude that breast-feeding shows an association with higher levels of antibodies to NTHi and P6, suggesting that breast-feeding modulates the serum immune response to NTHi and P6. Higher serum IgG might facilitate protection against AOM and NP colonization in breast-fed children.

BACKGROUND:The aim of this study was to assess the effectiveness of homeopathy compared to conventional treatment in acute respiratory and ear complaints in a primary care setting.

METHODS:The study was designed as an international, multi-centre, comparative cohort study of non-randomised design. Patients, presenting themselves with at least one chief complaint: acute (

RESULTS:Data of 1,577 patients were evaluated in the full analysis set of which 857 received homeopathic (H) and 720 conventional (C) treatment. The majority of patients in both groups reported their outcome after 14 days of treatment as complete recovery or major improvement (H: 86.9%; C: 86.0%; p = 0.0003 for non-inferiority testing). In the per-protocol set (H: 576 and C: 540 patients) similar results were obtained (H: 87.7%; C: 86.9%; p = 0.0019). Further subgroup analysis of the full analysis set showed no differences of response rates after 14 days in children (H: 88.5%; C: 84.5%) and adults (H: 85.6%; C: 86.6%). The unadjusted odds ratio (OR) of the primary outcome criterion was 1.40 (0.89-2.22) in children and 0.92 (0.63-1.34) in adults. Adjustments for demographic differences at baseline did not significantly alter the OR. The response rates after 7 and 28 days also showed no significant differences between both treatment groups. However, onset of improvement within the first 7 days after treatment was significantly faster upon homeopathic treatment both in children (p = 0.0488) and adults (p = 0.0001). Adverse drug reactions occurred more frequently in adults of the conventional group than in the homeopathic group (C: 7.6%; H: 3.1%, p = 0.0032), whereas in children the occurrence of adverse drug reactions was not significantly different (H: 2.0%; C: 2.4%, p = 0.7838).

CONCLUSION:In primary care, homeopathic treatment for acute respiratory and ear complaints was not inferior to conventional treatment.

BACKGROUND:The fact that breastfeeding may protect against allergic diseases remains controversial, with hardly any reports from developing countries. Prolonged breastfeeding was shown to reduce the risk of allergic and respiratory diseases.

AIM:The aim of this study was to assess the relationship between breastfeeding and the development of childhood asthma and allergic diseases in Qatari children at age 0-5 years. Additionally, this study investigated the effect of prolonged breastfeeding on the allergic diseases in a developing country.

DESIGN:This is a cross sectional survey.

SETTING:Well baby clinics and Pediatric clinics in the 11 Primary Health Care Centers and Hamad General Hospital, Hamad Medical Corporation, State of Qatar.

SUBJECTS:A multistage sampling design was used and a representative sample of 1500 Qatari infants and pre-school children with age range of 0-5 years and mothers aged between 18 to 47 years were surveyed during the period from October 2006 to September 2007 in Qatar. Out of the 1500 mothers of children, 1278 mothers agreed to participate in this study with the response rate of 85.2%.

METHODS:A confidential, anonymous questionnaire was completed by the selected subjects assessing breastfeeding and allergic diseases. Questionnaires were administered to women who were attending Primary Health Centers for child immunization. Questionnaire included allergic rhinitis, wheezing, eczema, and additional questions included mode and duration of breastfeeding, tobacco smoke exposure, number of siblings, family income, level of maternal education, parental history of allergies. Univariate and multivariate statistical methods were performed for statistical analysis.

RESULTS:More than half of the infants (59.3%) were exclusively breastfed, followed by infants with partial breastfeeding (28.3%) and artificial fed (12.4%). There was a significant difference found across these three categories of infants in terms of their age groups, smoking status of father, socio-economic status and parental consanguinity. Asthma (15.6%), wheezing (12.7%), allergic rhinitis (22.6%), and eczema (19.4%) were less frequent in exclusive breast fed children, compared to infants with partial breast feeding and formula milk. Ear infection (P = 0.0001) and eczema (P = 0.007) were found significant in infants with the history of maternal atopy, while asthma (P = 0.0001) and allergic rhinitis (P = 0.015) were found significant in infants with the history of paternal atopy. The main factors associated with mode of feeding were mothers having first baby, asthmatic mother and parental history of allergic rhinitis. The risk of allergic diseases, eczema, wheeze and ear infection in particular, were lower in children with prolonged breast feeding (>6 months) than in those with short-term breast feeding duration (<6 months).

CONCLUSION:The current study indicates that exclusive breast-feeding prevents development of allergic diseases in children. The main factors associated with breastfeeding for allergic diseases were being the first baby, maternal history of asthma, and parental history of allergic rhinitis. The study findings opens a big avenue for interventional role of breastfeeding. Therefore, we recommend breastfeeding is as one possible way to reduce the risk of onset asthma and allergic diseases in developing countries.

Methods of clinical application of gaseous ozone and ozonated solutions are described with special reference to the treatment of patients with acute and chronic suppurative middle ear diseases. Results of otoscopy, microbiological and cytological studies confirm therapeutic efficiency of the above techniques as accelerating recovery of patients with this pathology. It is recommended to include ozonotherapy as an additional method in the combined treatment of acute and chronic suppurative otitis media.

Ozone as gas and ozonized solutions were employed as treatment modalities in 28 patients with acute and chronic inflammatory diseases of the middle ear. Basing on otoscopy, bacteriological tests of the discharge from the middle ear cavity, number of washings before disappearance of the purulent discharge the conclusion was made that cure of patients on ozone therapy occurs 3-5 days earlier than in ozone-untreated patients. Ozone therapy is a beneficial adjuvant in combined treatment of otitis media.
