Taurodoncia múltiple: presentación de un caso / Multiple taurodontism: report of a case

La taurodoncia es una alteración morfológica de la anatomía dental que trae como consecuencia un cambio en la forma de la pieza dentaria, usualmente en las piezas multirradiculares. Consiste en un alargamiento de la cámara pulpar a expensas de los conductos radiculares, desplazando el piso pulpar hacia apical. El diagnóstico temprano y el seguimiento radiográfico son importantes. La mayoraía de las veces es un hallazgo radiográfico, dado que a la inspección clínica las piezas dentarias suelen verse normales. Puede presentarse aislado o asociado a otras anomalías dentarias. El propósito de este artículo es presentar un caso de taurodoncia múltiple que fue también un hallazgo radiográfico en un paciente de raza negra oriundo de Senegal y comunicar la alta incidencia de esta patología en dicho país.

Domestic transmission of Rift Valley Fever virus in Diawara (Senegal) in 1998.

In 1998, circulation of the Rift Valley Fever (RVF) virus was revealed in Diawara by detection of IgM antibodies in sheep and isolation of the virus from mosquitoes caught outside a village. A seroprevalence study was carried out. Finger-prick blood samples, individual and collective details were obtained. One thousand five hundred twenty people (6 months - 83 years) were included. Overall prevalence in this group was approximately 5.2%. The prevalence in infants (6 months - 2 years) was 8.5%. Age, gender, contact with a pond, presence of sheep, and abortion among sheep, and individual or collective travel history were not statistically associated with prevalence. Prevalence increased significantly when the distance to a small ravine, located in the middle of the village, decreased. The results suggest a low, recent, not endemic circulation of the virus. Culex quinquefasciatus was captured near the ravine. This mosquito, similar to Culex pipiens, can play a similar role in human-to-human transmission of the RVF virus.
