The aim of this study was to evaluate the shaping effects of two M-wire and two traditional nickel-titanium (NiTi) rotary systems in simulated S-shaped resin canals. ⋯ Within the limits of this ex vivo study, it was found that the manufacturing methods (M-wire or traditional NiTi) and kinematics (rotary or reciprocating motion) did not affect the shaping abilities of the systems. The extended file designs of highly tapered NiTi systems (ProTaper, WaveOne) resulted in greater deviations from the original root canal trace and more material removal when compared to less tapered systems (Sendoline S5, GT series X).

The objective was to determine the pattern of admission and outcome of patients in the Intensive Care Unit (ICU) of University of Nigeria Teaching Hospital (UNTH), Enugu, Nigeria. ⋯ The highest number of admissions into the ICU was for severe TBI following MVA. Developing a viable trauma team and separately equipped neurosurgical ICU with adequately trained and motivated staff will help improve the outcome of patients.

The objectives were to determine the seroprevalence of hepatitis B virus (HBV) infection and assess the major risk factors among Nigerian pregnant women. ⋯ The sero-prevalence rate of HBV infection and also its infectivity is high in Lagos, Nigeria. These findings thus support the need for a nationwide policy of routine and widespread HBV screening among pregnant women.

Stroke is a major cause of death and disability in population across the world. Hypertension is the most common stroke risk factor globally as well as in the Nigerian population, however other modifiable risk factors such as obesity are becoming increasingly prevalent due to unhealthy diets and sedentary lifestyle. ⋯ Stroke risk factors such as hypertension and obesity were common among the participants of the world stroke day awareness program in an urban area of Nigeria. Community screening and modification of these risk factors should be intensified in order to reduce stroke morbidity and mortality.

Acquired heart diseases (AHDs) are serious but largely preventable diseases. They are highly prevalent in developing countries where poverty, illiteracy, and poor socioeconomic conditions still pose a significant challenge. The prevalence and pattern of AHD among children have not been previously documented within the study area. ⋯ The pattern of AHD is similar to other studies in developing countries, with RHD being the most prevalent. There is a need for increased emphasis on primary prevention to reduce the burden of these diseases in the study area.
