Designer Drug (DD) abuse in Poland; a review of the psychoactive and toxic properties of substances found from seizures of illegal drug products and the legal consequences thereof. Part II--piperazines/piperidines, phenylethylamines, tryptamines and miscellaneous 'others'.

As the second and concluding part, this paper continues the summary review of the scientific evidence obtained from the literature and focuses on the remaining 4/6 groupings of DDs identified in illegal products found in the huge drug seizures made recently in Poland. They consist of piperazines/piperidines, phenylethylamines, tryptamines, (briefly mentioned), and a miscellaneous 'others' category; cannabinoids and cathinones derivatives having being reviewed in the first part. Also included in the introduction and discussion sections, in both reviews, are some legal aspects variously interwoven with the science.

Designer Drug (DD) abuse in Poland; a review of the psychoactive and toxic properties of substances found from seizures of illegal drug products and the legal consequences thereof. Part 1--cannabinoids and cathinones.

Faced with the rapidly growing increase of designer drug abuse, particularly amongst the younger generation, various legislative strategies are currently employed world-wide for tackling this problem - however with mixed results. The key issue is that the producers of DDs are able to either exploit existing legal substances intended for other uses, but which have been found to possess psychoactive properties, or to synthesise new psychoactive substances by introducing chemical modifications, often very minor ones, thereby avoiding the prohibited use of chemicals included on any banned lists. Some countries opt to ban new drugs as and when shown or considered to be harmful, while others introduce sweeping bans based on chemical structure.

Managing water safety in healthcare. Part 2--practical measures and considerations taken for waterborne pathogen control.

These summaries form the second part of presentations made at a recent conference held at the Royal Society for Public Health in London, 16-17 May 2012, on the latest developments in combating waterborne hospital-acquired infections (nosocomial). The first part (Ann Agric Environ Med 2012; 19(3): 395-402) has focused more on the adopted strategies/approaches from the UK perspective, (some also from continental Europe), whereas the presented second part (sections 1-7 below), is dedicated more to practical solutions, and examples of features used in water systems that are or have been considered effective.

Managing water safety in healthcare. Part 1--Strategies and approaches for waterborne pathogen control.

Summaries in 2 parts are presented from a conference held in London at the Royal Society for Public Health on 16-17 May 2012, on the latest developments in dealing with waterborne hospital-acquired infections (nosocomial), from the UK perspective. Also included were some views from continental Europe. The first part, focuses on management strategies and plans that are either in use or recommended by domestic/international guidelines, such as the WHO, for prevention, control and risk assessment of disease outbreaks resulting from the presence of these pathogenic microorganisms in water appliances/supplies.

Public health hazards in Poland posed by foodstuffs contaminated with E. coli O104:H4 bacterium from the recent European outbreak.

Shiga toxin producing Escherichia coli (STEC) are the most virulent diarrhoeagenic E. coli known to date. They can spread with alarming ease via the food chain, as recently demonstrated by the large outbreak of STEC O104:H4 borne by sprouted seeds in 2011, clustered in northern Germany, and subsequently affecting other countries.
