A geographical analysis of ethnic distribution of jaw ameloblastoma in Nigerians.
Ameloblastoma is the most common odontogenic tumour in Nigeria. A definite geographic variation has been observed in the frequency of odontogenic tumors from different parts of the world. However, there is no study on the regional variations in Nigeria. Hence, this study was designed to document the ethnic and geographical distribution of jaw ameloblastoma in Nigeria. ⋯ The study hypothesized that the geographical distribution of ameloblastoma in Nigeria is the result of all or one of the following: the country's tropical climate, migration patterns and health seeking behavior. Hopefully, these claims should lead to further enquiry on the underlying causes.

Relationship between household wealth and childhood immunization in core-North Nigeria.
Childhood immunization rate is lowest in the core-North Nigeria. We examined the relationship between inequality in household wealth and complete childhood immunization in that part of the country. ⋯ Disparities existed in childhood immunization between the poor and rich in the core-North part of Nigeria. Policy makers should institute effective interventions that will assist children from poor households to improve their immunization access.

Nickel challenge up regulates CD69 expression on T lymphocyte sub-sets from patients with nickel induced contact dermatitis.
Persistent antigenic stimulation due to repeated exposure to nickel may lead to chronic inflammation resulting in allergic contact dermatitis (ACD). ⋯ CD69 molecule appears to be an important regulator of immune response in nickel contact dermatitis.
