Review of the demographic factors and toxicology related to deaths due to pregabalin in Northern Ireland.

The potential for recreational abuse of the analgesic and antiepileptic drug pregabalin is now well established in the literature. The potential minimum lethal dose in post mortem cases is however less defined. All post mortem examinations in Northern Ireland where the cause of death was found to be due to pregabalin were examined for demographic and toxicological analysis.

In-situ fluorescence spectroscopy is a more rapid and resilient indicator of faecal contamination risk in drinking water than faecal indicator organisms.

Faecal indicator organisms (FIOs) are limited in their ability to protect public health from the microbial contamination of drinking water because of their transience and time required to deliver a result. We evaluated alternative rapid, and potentially more resilient, approaches against a benchmark FIO of thermotolerant coliforms (TTCs) to characterise faecal contamination over 14 months at 40 groundwater sources in a Ugandan town. Rapid approaches included: in-situ tryptophan-like fluorescence (TLF), humic-like fluorescence (HLF), turbidity; sanitary inspections; and total bacterial cells by flow cytometry.
