Survey of ENT services in Africa: need for a comprehensive intervention

Johan Fagan; Marian Jacobs

Background: Burden of disease (BOD) is greatest in resource-starved regions such as Africa. Even though hearing disability ranks third on the list of non-fatal disabling conditions in low- and middle-income countries, ear, nose, and throat (ENT) disorders are not specifically coded for within the framework governing global BOD estimates, and in discussions about health challenges, non-communicable diseases receive scant attention. Implementing cost-effective interventions to address conditions largely neglected by global estimates of BOD such as hearing loss are important contributors to health and economic development. Objectives: Establish a database of ENT, audiology, and speech therapy services in Sub-Saharan Africa; create awareness about the status of these services; propose effective intervention; gather data to lobby African governments, donor countries, and aid organizations; determine need for Developing World Forum for ENT, Audiology, and Speech Therapy services. Design: Survey of ENT, audiology, and speech therapy services and training in 18 Sub-Saharan Africa countries. Results: There is an alarming paucity of services and training opportunities, and there is a large gap between higher technology, expensive health care in high-income countries and lower technology, low-cost practice in low-income countries. Conclusions: Lower technology and lower cost Developing World medical practice should be recognized and fostered as a field of medical practice, teaching, and research. Developing World centers of excellence must be fostered to take a lead in teaching, training, and research. A Developing World Forum for ENT Surgery, Audiology, and Speech Therapy, directed and driven by Africa and the Developing World, supported by the First World, should be established, to develop a comprehensive intervention to turn around the severe shortage of services and expertise in the Developing World. Global health policies and practices should include new norms and standards which serve the interests of the global community, and are based on current realities of global health.

BackgroundSouth Africa has one of the highest incidences of multidrug-resistant tuberculosis (MDR-TB) in the world. Concomitantly, aminoglycosides are commonly used in this country as a treatment against MDR-TB. To date, at least five mutations are known to confer susceptibility to aminoglycoside-induced hearing loss. The aim of the present study was to develop a rapid screening method to determine whether these mutations are present in the South African population.MethodsA multiplex method using the SNaPshot technique was used to screen for five mutations in the MT-RNR1 gene: A1555G, C1494T, T1095C, 961delT+C(n) and A827G. A total of 204 South African control samples, comprising 98 Mixed ancestry and 106 Black individuals were screened for the presence of the five mutations.ResultsA robust, cost-effective method was developed that detected the presence of all five sequence variants simultaneously. In this pilot study, the A1555G mutation was identified at a frequency of 0.9% in the Black control samples. The 961delT+C(n) variant was present in 6.6% of the Black controls and 2% of the Mixed ancestry controls. The T1095C, C1494T and A827G variants were not identified in any of the study participants.ConclusionThe frequency of 0.9% for the A1555G mutation in the Black population in South Africa is of concern given the high incidence of MDR-TB in this particular ethnic group. Future larger studies are warranted to determine the true frequencies of the aminoglycoside deafness mutations in the general South African population. The high frequencies of the 961delT+C(n) variant observed in the controls suggest that this change is a common non-pathogenic polymorphism. This genetic method facilitates the identification of individuals at high risk of developing hearing loss prior to the start of aminoglycoside therapy. This is important in a low-resource country like South Africa where, despite their adverse side-effects, aminoglycosides will continue to be used routinely and are accompanied with very limited or no audiological monitoring.

Survey of otolaryngology services in Central America: need for a comprehensive intervention.

Richard Wagner; Johan Fagan

In the developing world, there exists a scarcity of services and training in otolaryngology, audiology, and speech therapy, which is reflected by the gap between health care delivery in high-income countries and low-income countries. We surveyed, by questionnaire, the countries of Central America, except for Belize, because of the lack of otolaryngology services, on the following issues: availability of otolaryngology, audiology, and speech therapy services and equipment; otolaryngologist, audiologist, and speech therapist training; and availability of services in rural areas. Surveys were distributed via email and by hand at the 2011 Central American Congress of Otolaryngology, in San Salvador, El Salvador, to otolaryngologists, audiologists, and speech therapists. Not to our surprise, there is a shortfall in services and training in all three professions. The data collected and presented in this commentary will provide a basis by which change might take place.

We look at the OSD process, and identify the potential impact of its deficiencies, on the state health system and teaching programs. Furthermore we look at the bargaining process available to state doctors, and suggest ways that this could be improved.
