Type B aortic dissection involving an isolated right-sided aortic arch.

We report a case of a 48-year-old man in whom type B aortic dissection in the right aortic arch and right descending aorta was diagnosed by transesophageal echocardiography and computed tomographic scan. Angiography was necessary to define the anatomy of the branching vessels. The patient was successfully treated by interposition of a Vascutek 24-mm Dacron woven tube with a right posterolateral thoracotomy approach.

Working with communities to increase the use of health services: an experience from togo, west Africa.

A project in Togo, West Africa, demonstrated that motivated and skilled district health teams can increase community involvement in promoting positive health behavior. Village health committees, village volunteers, health workers, itinerant health agents, and school teachers collaborated with district health personnel in village-wide efforts to increase the use of health services targeted to children under five years of age. The project also demonstrated that in areas where health services are accessible, high levels of service utilization can be achieved by villages through a combination of strategies that rely on person-to-person and group methods of communication.

The acceptability of childhood immunization to Togolese mothers: a sociobehavioral perspective.

A study was conducted in Togo to investigate the lack of acceptance of childhood immunization from a social science perspective. In each village focus group interviews were conducted with approximately 12 mothers to discuss their beliefs and knowledge, social and cultural norms and practices, and experiences with health services that hinder or promote the acceptability of childhood immunization. The problem of failure to complete the immunization series was explained in terms of mothers' lack of knowledge of when to return or their forgetfulness rather than inadequate knowledge about the importance of returning.
