Prevalence of chronic ear disease among HIV+ children in Sub-Saharan Africa.

Objectives: To determine the prevalence of chronic ear disease in HIV+, highly active anti-retroviral therapy (HAART)-treated children and compare this to the prevalence in healthy children of similar age living in a similar setting.

Introduction: From previous clinical work in Ethiopia, we suspected that chronic middle ear disease was common both in the general pediatric population and especially among children with HIV/AIDS. Few studies have examined the prevalence of chronic ear disease in HIV + children, particularly in those treated with HAART.

Prevalence of hearing-loss among HAART-treated children in the Horn of Africa.

Objectives: The prevalence of hearing loss (HL) in children infected with HIV/AIDS is not well studied. Even fewer studies focus on stable HIV-infected children treated with high-effective antiretroviral therapy (HAART). We aim to compare the prevalence of ear disease and HL in HAART-treated, HIV + children in Addis Ababa, Ethiopia with a well, similarly-aged elementary school population with unknown HIV status (HIVU).

Results of pediatric tympanoplasty on short-term surgical missions.

Objectives/hypothesis: To determine the safety and effectiveness of pediatric tympanoplasty performed on short-term international medical missions.

Study Design: Prospective observational study.

Methods: Ethiopian children who had dry or nearly dry tympanic perforations and bilateral conductive hearing losses underwent postauricular tympanoplasties with underlain temporalis fascia grafts.

Investigation of antibacterial activities of Albizia gummifera and Ferula communis on Streptococcus pneumoniae and Streptoccus pyogenes.

Background: Respiratory Tract infections continue to be a major cause of morbidity and mortality world wide. There is a failure to treat respiratory infections due to the emergence of antibiotic resistant strains among the most common respiratory pathogens.

Objectives: To evaluate the in vitro antibacterial activities of two traditionally used plants: Albizia gummifera (Ambabesa-Muka, Oromifa, Sessa-Amharic.

Sensorineural hearing loss in children with epidemic meningococcal meningitis at Tikur Anbessa Hospital.

There are several reports on epidemic meningococcal meningitis in some areas of Ethiopia, which lie in the meningococcal meningitis belt of Africa. Very little is known about the neurological sequel of epidemic meningococcal meningitis, especially that of hearing loss. This hospital-based study was conducted prospectively at the Ear Nose Throat clinic of the Pediatric Outpatient Department of the Tikur Anbessa Hospital during the meningococcal meningitis epidemic from May to October 2000 in order to assess the hearing status of patients after completion of their course of treatment.
