It is often secondary to nasopharyngitis, which favors the passage of infection through the Eustachian tube to the middle ear. The aim of our study was to improve the management of AOM in the Paediatric Department of the Hospital National Ignace Deen (Conakry). Patients and Methods: This was a prospective descriptive study lasting 6 months from 01 July to 31 December 2011;the study covered 525 cases out of a total of 6276 children, i.e. a frequency of 8.36%. Results: The most affected age group was 6 to 11 months. Males predominated (69.71%). 82.29% had a history of recurrent rhinopharyngitis. The most frequent reason for consultation was incessant crying (66.29%). Rhinopharyngitis and malaria were the most commonly associated pathologies (87.62% and 39.62% respectively). 72.19% of our patients were admitted with congestive AOM and received medical treatment. We recorded one case of otomastoiditis which was treated surgically. Conclusion: AOM is more common in children aged between 6 and 24 months. Good collaboration between paediatricians and ENT specialists is essential to reduce the morbidity of AOM.展开更多

The objective was to determine the effects of allspice on the AOM induced aberrant cryptic foci (ACF) in colon of Fisher 344 male rats. Rats were obtained from Harlan, IN, and raised in an environmentally controlled condition of 12 hours of light and dark cycles and at 50% relative humidity. Rats in experimental groups were fed with different concentrations of allspice (0.5%, 1% and 2%) in an AIN-93G based diet. Rats received AOM injections at 7 and 8 weeks of age at 16 mg/kg body weight. After 17 weeks, rats were asphyxiated with CO2, and liver, and colon samples were collected. Colons were stained with methylene blue to enumerate ACF and crypt multiplicity. Rats fed 0.5% allspice had the highest cecal pH (7.64) compared to control (6.88) (P ≤ 0.05). Rats in the treatment groups gained 225 g to 251 g over the 13-week period. A 29% reduction in total crypts was observed in rats fed 2% compared to 0.5% allspice. Highest number of crypts was seen in control group. Antioxidative enzyme activity was higher in rats fed allspice compared to the control group. Total tumors (0.25 - 2.5), tumor bearing rat ratio (1 - 2.5) and incidence rate (50% - 100%) in rats fed different concentrations of allspice were lower compared to rats in the control group (6.6%, 5.8%, and 100% respectively). Consumption of allspice in the diet reduced the number of ACF in Fisher 344 male rats. Allspice can be utilized in food formulations for its chemopreventive effects against colon cancer.展开更多
