The complex relation between access to opioid agonist therapy and diversion of opioid medications: a case example of large-scale misuse of buprenorphine in the Czech Republic.

Opioid agonist therapy (OAT) has been available in a standard regime in the Czech Republic since 2000. Buprenorphine is the leading medication, while methadone is available only in a few specialised centres. There is an important leakage of buprenorphine onto the illicit market, and the majority of Czech opioid users are characterised by the misuse (and injecting) of diverted buprenorphine medications.

HIV epidemic among men who have sex with men in the Czech Republic, 2016: high time for targeted action.

Reported incidence of human immunodeficiency virus (HIV) infection in the Czech Republic increased steeply over the past decade from 90 new cases in 2005 to 266 in 2015. This increase is almost exclusively attributed to sexual transmissions between men who have sex with men (MSM). In 2015, there were 79% (n=210) newly diagnosed cases among MSM, 17% (n=45) were attributed to heterosexual transmission and 1% (n=3) to people who inject drugs.

"It can't happen to me": Alcohol drinkers on the 2012 outbreak of methanol poisonings and the subsequent prohibition in the Czech Republic.

Background: In September 2012, a series of methanol poisonings occurred in the Czech Republic as a result of an influx of illicit alcohol into (predominantly) cheap alcoholic beverages on the retail market. The public authorities decided to prevent public health risks by prohibiting sales of liquors that contained more than 20% alcohol (> 20% liquor). The "partial" prohibition lasted for almost two weeks, but the poisonings still continued.

Long-term visual damage after acute methanol poisonings: Longitudinal cross-sectional study in 50 patients.

Context: Visual disturbances due to the toxic effect of formic acid in acute methanol poisonings are generally transient. The subjective symptoms of visual toxicity may resolve within few weeks and fundoscopic signs of acute optic neuropathy subside within 1-2 months; therefore, the prevalence of long-term visual sequelae in the population of survivors of poisonings may be underestimated.

Objective: To study the prevalence and character of long-term visual sequelae of acute methanol poisonings based on the data from the Czech mass methanol outbreak in 2012.

Rare alleles within the CYP2E1 (MEOS system) could be associated with better short-term health outcome after acute methanol poisoning.

Genetic polymorphisms influence the metabolism of ethanol and methanol, but the potential effects of genetic predisposition on the clinical course, outcome and short-term health sequelae of acute methanol poisoning are unknown. To evaluate the role of the MEOS system in methanol poisoning, we analysed the effect of three polymorphisms (RsaI - rs2031920; PstI - rs3813867; insertion/deletion I/D) within the CYP2E1 enzyme (MEOS system) in 50 adult survivors of methanol poisoning and compared their genotype frequencies with 460 controls. The minor allele frequencies of all three polymorphisms were below 5% in both groups.

Mortality of cohort of very young injecting drug users in Prague, 1996-2010.

Aim: To determine the mortality in a cohort of very young injecting drug users (IDUs), and the factors associated with it.

Design: A database linkage prospective (follow-up) cohort study.

Setting: A convenience sample of clients of 2 low-threshold facilities, 1 drug treatment clinic, and one special facility for children with severe behavioural disorders, who were all younger than 19 and older than 15, was interviewed one or more times in 1996-8 and asked to agree with their being interviewed again after 10 or more years.
