A systematic investigation of single solute, binary and ternary PFAS transport in water-saturated soil using batch and 1-dimensional column studies: Focus on mixture effects.

This study aimed to investigate the transport and release of per- and polyfluoroalkyl substances (PFAS), as single solutes and binary and ternary mixtures, and associated competitive sorption effects in water-saturated soil. Batch sorption isotherm and desorption, and one-dimensional miscible displacement studies were conducted. For the batch study, the mixtures exhibited extensive sorption isotherm nonlinearity at aqueous concentrations exceeding 20 µg/L.

TRANSMIGRATION OF INTRA-UTERINE DEVICE, EXPLORATORY LAPAROTOMY, RETRIEVAL AND REPAIR OF PERFORATED UTERUS.

Background: Perforation of the uterus following transmigration of Intra-uterine devise (IUD) is an uncommon finding of insertion of IUD. There is associated increased risk of accidental pregnancy,morbidity and mortality.

Aim: To report a rare clinical condition in which there was uterine perforation following migration of IUD and to increase awareness of this condition in our environment.

Prostatic tumours in Benin City, Nigeria.

Prostatic tumours accounted for 10.2% of all surgical specimens from male patients received in the Department of Anatomic Pathology of the University of Benin Teaching Hospital, Nigeria between 1973 and 1990. Nodular prostatic hyperplasia accounted for 83% of the cases and the peak age incidence was in the sixth decade of life.
