A retrospective 5-year review of all cases of abruptio placentae managed at the University of Abuja Teaching Hospital between 2012 and 2016 was carried out. The patients’ case notes were retrieved from the records department of the hospital and studied for socio-demographic characteristics, parity, gestational age, clinical presentation, risk factors for abruptio placentae, foetal and maternal outcomes.

Parity was not significantly associated with abruptio placenta (p=0.73). Abruptio placentae occurred more frequently amongst unbooked women (70.9%). Maternal complications were postpartum haemorrhage (16.4%), haemorrhage shock (10.9%), postpartum anaemia (acute) (21.8%), and puerperal sepsis (3.6%).

Objective: This study was conducted to determine the presence of lead in potable water sources in Anambra state, Nigeria. Materials and Methods: Water samples were systematically collected from 81 water sampling sites in different senatorial zones of the state. Lead was estimated in the water samples using Varian AA240 atomic absorption spectrophotometer. Results: The mean levels of lead in the water samples in all the senatorial zones of the state were higher than the maximum contaminant limit (0.01 mg/L) set by the World Health Organization (WHO).

Furthermore, Anambra South has higher (P < 0.001) mean lead level compared to the North and Central senatorial zones.

Materials and Methods: This study is a prospective cross-sectional study conducted in two university teaching hospitals in North Eastern Nigeria. Sixty patients were recruited for the study. Thermoluminescent dosimeter (TLD) chips were exposed for craniocaudal (CC) and mediolateral examinations to record the entrance skin dose (ESD). TLD readings were obtained at the Center for Energy Research and Training Zaria, Kaduna State, Nigeria. Dance formula was used to convert ESD to mean glandular dose (MGD). Student's t-test was used to determine the relationship between the mean ESD obtained in the two centers and Pearson's correlation was used to determine the relationship between the MGD and anthropotechnical parameters. Statistical significance was set at P < 0.05. Results: The total MGD for this study was 0.31 ± 0.05 mGy and 0.69 ± 0.11 mGy for CC and mediolateral oblique (MLO), respectively.
