comparison of different antibiotics in treatment of acute otitis media in children

Acute otitis media is the most prevalent disease of childhood following respiratory tract infections. In addition, several complications which may be life treatening can occure. This study was performed to determine the clinical responses of acute otitis media to different antibiotics and also the selection of most suitable antibiotic for treatment. In this study, 141 individuals with acute otitis media were visited as out patients in Amir- Al-Momenine Hospital and private clinics by ENT Specialists. The patients for whom no antibiotic was preseribed for the last episode of disease, were randomly divided into four groups and each group was given a ten-day course of Treatment with one of following antibiotics: Amoxcillin, coamouxy clav, cefixim and co-trimaxazole. Twelve to sixteen days following the treatment the clinical responses were evaluted using Chi-Square test to investigate the hypothesis. Clinical in group with coAmoxyclav 86.6%, Amoxycillin 84.4%, cefixim 83.9% and cotrimxazol 80.6% improvement was observed. Statistically, no significant difference was fount between four groups. The data of this study showed that the efficacy of these antibiotics to treat the uncomplicated acute otitis media is equal

Investigation of bacterial agents prevalence and their antibiotic susceptibility pattern in acute diffuse otitis externa in Semnan [2000-2003]

Acute diffuse otitis externa is one of the most common type of the otitis externa, also known as "Swimmers ear". In most cases bacterial agents are pathogens associated with this infection. P. aeruginosa and S. aureus are most common bacterial agents. In creasing antimicrobial resistance to many antibiotics, adds to the challeng of optimizing empric treatment for complicated otitis externa. The subject of this study is to determine the bacteriology of acute otitis externa and the susceptibility profiles of isolated bacteria to selected antibiotics External ear canal discharg swabs, collected from 70 acute otitis externa were inculated [at 35°C for 14 hrs] in thiologycolat broth, sheep blood and mac conkyagar. All isolates recovered were identified to species level by grams staning and biochemical media. Antibiotic susceptibility test has been done using Kirby-bauer method 89.2% of patients were women. 73 bacterial agents were isolated from 70 samples. P. aeruginosa and S. aureus were the most common recovered organism. 94.5% of isolated bacterial agents were susceptible to Ciprofloxacin and 89% to Gentamycin. The least antibiotic susceptibility was to Amoxicillin [5.5%], Cloxacillin [10.9%] and Ampicillin [15.7%] Our study showed that prevalence of acute diffuse otitis externa is higher in female sex [89.2%] and was seen in ages of 20-29 years. About 90% of isolated bactrial agents were susceptible to both Amoxicilin and Gentamycin. Findings [sex and age of infection] of this study were different from those of similar study. The underling causes of observed contraversy were discussed

Incidence of hearing disorders in fifth-year primary school students of Semnan in the academic year 2002-2003

Congenital or acquired hearing disorders may cause conductive or sensory-neural low hearing. In addition, non-sufficient development of Eustachian tube and mastoid cells old may cause conductive hearing disorders in children under 12 years old. Thus, performing hearing screening studies in this range of ages may help us to identify the children with hearing disorders. By detecting the type of hearing disorders, it is possible to help these children in their learning procedure. By considering these, the present study has been designed to investigate the hearing conditions in the primary school children [fifth level] of Semnan city. In order to determine the prevalence of hearing impairment in primary school children [fifth level], this study of 2081 children was performed in two stages. In the first stage, these children were screened by otoscopy, pure tone audiometry [three frequencies of 500, 1000 and 2000 Hz at 20 dB]. In the next stage, the suspected students with hearing loss referred to the audiometry clinic to undergo a complete tests including; 1] speech audiometric tests, 2] audiometric tests with frequencies of 250, 500, 1000, 2000, 4000 and 8000 Hz, and 3] tympanometry tests to determine the type of hearing loss. The results indicate 6.9% of impacted cerumen, 17.9% of slight cerumen, 3.6% of tympanic disorder and 4.1% of hearing loss among the fifth-level students, with significantly higher hearing loss in the south area compared to the other area [P<0.05]. The percentage of impacted cerumen was twice in the student girls, compared to the boys [P<0.05], while the percentage of observed tympani disorder was five times in the boys compared to the girls [P<0.01]. No difference was seen between boys and girls students in term of observed hearing loss. The obtained results showed the presence of impact cerumen, tympani disorder and hearing loss in the fifth level primary school children which indicate the importance of performing such a screening studies and also planning the health training programs for preventive care of hearing loss in the school and family
