Objectives: The aim of this study has been to assess the characteristics of acute poisoning deaths in Poland over a period of time 2009-2013., Material and Methods: The analysis was based on the data obtained from the patient records stored in toxicology departments in 6 cities - Łódź, Kraków, Sosnowiec, Gdańsk, Wrocław and Poznań. Toxicological analyses were routinely performed in blood and/or urine. Major toxic substances were classified to one of the following categories: pharmaceuticals, alcohol group poisonings (ethanol and other alcohols), gases, solvents, drugs of abuse, pesticides, metals, mushrooms, others. Cases were analyzed according to the following criteria: year, age and gender of analyzed patients, toxic substance category and type of poisoning. The recorded fatal poisonings were classified according to the International Classification of Diseases., Results: The record of 261 deaths were retrospectively reviewed. There were 187 males (71.64%) and 74 females (28.36%) and the male to female ratio was 2.52. Alcohol group poisonings were more frequently responsible for deaths in men compared to all poisonings, 91.1% vs. 71.6%, respectively (p < 0.05), and pharmaceutical agents were more frequently responsible for deaths in women, 47.4% vs. 28.4%, (p < 0.05). Methanol was the most common agent in the alcohol group poisonings, accounting for 43.75% (N = 49), followed by ethylene glycol, 39.29% (N = 44), and ethanol, 16.96% (N = 19)., Conclusions: Epidemiological profile data from investigation of poisoning deaths in Poland may be very useful for the development of preventive programs.

The aim of the paper was to study frequency of laboratory determinations and toxicological information related to over-the-counter drugs (OTC): paracetamol (acetaminophen), salicylates and dextromethorphan. The research was based on data from Toxicological Laboratory and Poison Information Center UJ CM in Krakow in years 2010-2015. Paracetamol was determined averagely 102 times a year, more than 50% (57 cases) were positive with confirmation of poisoning. The least number of paracetamol poisoning was noted in 2011 (35 cases), the most were in 2015 (98 cases). In the time span there were averagely 40 salicylates check measurements a year, less than 50% (15 cases) were positive. Dextromethorphane was confirmed averagely in 31 patients a year, decrease of the drug intoxications was noted in 2013-2015. Paracetamol and dextromethorphan were the most often the cause of poisoning in group of patients 13-18 years old, salicylates – more than 30 years. In the group of small children there were only a few poisonings with paracetamol. Toxicological information data related to paracetamol, salicylates and dextromethorphan were similar to data from toxicological laboratory. Mean year numbers of drug poisoning information were: 90 (paracetamol), 14 (salicylates), 30 (dextromethorphan). The differences were in patients age distribution. Acute poisonings with OTC were related mainly to paracetamol, young patients (13- 18 years) and young adults (19-29 years). Salicylates poisoning information were related mainly to the group of adult patients (> 30 years), dextromethorphan was abused mainly by oung patients (13-18 years). There were no observed poisonings with salicylates and dextromethorphan in children, but there were toxicological information about paracetamol and salicylates poisoning and overdose in group of children (1-6 years).

The total number of out-patients and hospitalized poisoned patients above 14 years old in Krakow in 1966 was 520 and 2132 in 1983. The incidence of poisoning per 10 000 of Kraków population in 1966 was 25.0 and increased to 36.2 in 1983. The mortality in 1966 was 0.75%. It was low also in 1983 – 1.01%, whatever reached 7.8% if forensic data were included (the fatalities on the spot). There were 847 poisoned patient hospitalized in Clinic of Toxicology UJ CM in 2015 and mortality in this group was 1.06%. Forensic analysis shown decreasing number of deaths on the spot (154 in 1983 and 89 in 2015). The percentage of poisoned with ethanol was declining (78.9% in 1983 and 57.3% in 2015). The frequency of patients treated in intensive care unit were increased from 6% in 1966 to 21.7% in 2015. The percentage of addicted acute intoxicated patients was lower (8%) in 1983 and achieved 21.7% in 2015. Poisoning structure, particularly pharmaceuticals, significantly influenced medical procedures performed in intensive care unit, especially administration of antidotes (5% in 1966 and 48.9% in 2015). Social evolution and changes of culture habits increased percentage of addiction but the number of deaths caused by ethanol on the spot was smaller.

A telephone inquires to Poison Information Centre and data from toxicological laboratory of Jagiellonian University Medical College related to cases below 19 years of age in 2010 -2012 were analyzed. 37.3% of 3692 information given were related to children and adolescent toxic exposure. Most telephone inquires concerned youngest children (below 6 years); toxicological analysis were ordered in the oldest group (13-19 years) mostly.

There were 10 636 toxicological information given in 2004-2008 by the Poison Information Center Jagiellonian University Medical College. 538 of them concerned NonSteroidal Anti-Inflammatory Drugs (NSAIDs); 336 cases of NSAIDs ingested alone and 202 co-ingested with other drugs and/or with ethanol. 58,9% of them were intentional and 29,6% were accidental. Children (1-6 years) and adolescents (15-19 years) were mostly involved.

Poison information centres (PIC) provide telephone advice on the treatment of poisonings to the lay public and medical professionals. The number of inquiries increases every year. Poison Information Centre of Collegium Medicum of Jagiellonian University in Krakow provided 1611 items of advice in 1999 and 2263--five years later--in 2004. Each incoming call is recorded and documented by standardized protocol. Another aspect of PIC activity of is prevention and education. Inquiries protocols' analysis shows the most frequent reasons and circumstances of poisonings. Thus, it is possible to conduct appropriate prophylactic campaigns. The above aspects of activity of PIC do not bring direct financial benefit. There is one index which shows that PIC saves the money. There were 335 cases in 2004 (above 50% consulted lay public) when unnecessary hospital admissions were prevent. It should be noted that the others were refer to proper specialist. This aspect of PIC's activity significantly decreases the costs which should be paid in any medical intervention.

The pattern (frequency, type of exposure, toxic substance) of adolescent and adult poisonings in Kraków in 2003 is compared with 1983. The analysis includes data for poisoned patients treated at the Kraków Department of Clinical Toxicology and all on the spot fatal cases subjected to post-mortem autopsy and toxicological examinations at the Department of Forensic Medicine Jagiellonian University Medical College in both the years. As much as 4341 poisoning cases (2852 males; 1489 females) were treated in 2003 compared with 2132 (1078 males; 1054 females) in 1983. In 1983 in group of 154 poisoned persons who died at the place of accident there were 138 (89.6%) men and 16 (10.4%) women. In 2003 among 121 deaths at the scene there were 93 (76.9%) males and 28 (23.1%) females. Poisonings due to suicidal attempts decreased significantly from 53.6% in 1983 to 19% in 2003. Incidence of poisoning per 10 000 of general Kraków population increased from 36.17 in 1983 to 57 in 2003 or up to 65.7 if the population of adults and teenagers (above 15 years old) was only considered. Pharmaceuticals (40.6%) followed in frequency by ethanol (25%) and ethanol co-ingested with pharmaceuticals (12.2%) and carbon monoxide (10.6%) were the most common reasons for poisoning in 1983. In 2003 the most common cause of poisonings was ethanol (46.2%) followed by pharmaceuticals alone (25%) or co-ingested with ethanol (6.4%) and carbon monoxide (6.2%). An ingestion of mixed pharmaceuticals (55.1%) followed In frequency by non-barbiturate hypnotics and psychotropic drugs (26.3%) were a most common in 1983 whereas a non-barbiturate hypnotics and psychotropic drugs (34.4%) followed by mixed pharmaceuticals (32.9%) in 2003. A mortality both concerning only the people who died in hospital and also those who died on the spot (prior to any treatment) was significantly higher in 1983 compared with 2003.

509 toxicological telephone inquiries concerning children under 15 years have been provided by Kraków Poison Information Centre (PIC) in the year 2004. Medication drugs were involved in almost one half (n=208) the cases noted. 63.7% of calls concerned children under 4 years with a two-year-old group predominance. The main reason for poisoning in children under 4 were pharmaceuticals (42.6%), followed by pesticides (9.8%), corrosives (8.8%), hydrocarbons (8.1%), plants (5.5%) and detergents (3.7%); all exposure were accidental. Suicide attempts reached 32.3% in the 12-14 age group. In that group also a cases of psychoactive substances overdosing were noted. Most exposures in children reported to poison centre were accidental (87.2%). Thus, it is absolutely necessary to intensify prevention and education activity both for parents and primary school children to avoid the poisoning.

The patterns (frequency, poisoning type, toxic agent involved) of adolescent and adult poisonings in Kraków in 1972 and 2002 are presented. The analysis includes data for poisoned patients treated at the Kraków Department of Clinical Toxicology in 2002 and 1972, and all on the spot fatal cases subjected to post-mortem autopsy and toxicological examinations at the Department of Forensic Medicine in both the years. As much as 4116 poisoned cases (males 2722; females 1394) were treated in 2002 compared to 1485 (males 649; females 836) in 1972. There was no substantial difference between a number of poison related fatalities on the spot in years analysed: 126 (males 105; females 21) in 2002 and 122 (males 84; females 38) in 1972. An elevation in poisoning incidence rate per 10,000 of Kraków inhabitants was also noted in 2002 compared to 1972 (54.3 vs. 30.0). A pharmaceuticals (32.9%) followed by CO (18.2%) and mixed pharmaceuticals (16.2%) were mostly involved in poisoning cases in 1972, whereas ethanol (46%), pharmaceuticals (13.2%), pharmaceuticals co-ingested with ethanol (7.8%), narcotics (7.8%), mixed pharmaceuticals (6.7%), and CO (5.2%) were mostly involved in poisoning cases treated in 2002. A mortality rate both concerning only a people who died in hospital or/and those who died on the spot (prior to any treatment) was significantly higher in 1972 compared to 2002.

The pattern of poisonings in patients hospitalised in the Department of Clinical Toxicology Jagiellonian University Medical College in 1997-2001 was presented in the study. The analysis includes 17,931 patients: 6,016 (33.5%) women and 11,915 (66.4%) men. The rate of patients between 20-39 years old was highest in all the analysed year, however downward trend was noticed. The upward tendency was noted in older group of poisoned patients. A suicidal poisonings were mostly common in 1998 and 1999 in the youngest and oldest groups: 37.1%, 37% in 1998, and 25.5%, 22.2% in 1999 respectively. The medication drugs were the most common cause of acute poisoning only in the group of adolescent patients. Ethyl alcohol was the common cause of poisoning in adult groups. The highest rate of ethanol intoxication was noted in patients between 40 to 59 years old. A 89 lethal intoxication were noted in analysed period. The average mortality rate was low (0.5). A medication drugs (30.4%) followed by ethanol (17.4%), carbon monoxide (13%) and solvents (13%) were involved in lethal poisonings in the oldest group of patients.

The role of toxicological information consisting of chemical substance toxicity, clinical signs and symptoms, treatment and diagnosis of poisonings is presented in the study. These data are collected in computer programmes TOKSY 5, TOKSY7 (MacroSoft Warazawa) which together with American CCIS data base (MICROMEDEX, Denver, Colorado) and IPCS INTOX Database are helpful instrument while giving the toxicological information or/and medical consulting. All cases are registered in IPCS (International Programme on Chemical Safety) INTOX SYSTEM data base that enables epidemiological analysis and also an evaluation of economical and social effects caused by poisonings.

The aim of the study was to evaluate a frequency and the course of acute poisonings with psychoactive substances in abusers, considering the kind of toxic substance. 25% of all acute poisonings treated in the Department of Clinical Toxicology in the year 1996 that were acute poisonings with psychoactive substances among the abusers of Kraków adult population. Alcohol followed by narcotics and drugs and by organic solvents was predominant cause of acute poisonings in that group. Opiates derivatives as the so called kompot produced at home from poppy straw or juice of poppy head were the most common narcotics. Pure amphetamine was detected only in 5.3%, while as combination with other narcotics (opioids, THC, LSD) was detected in 31.2% of narcomans and drug abusers. The combination of opioids, barbiturates and benzodiazepines was predominant cause of acute intoxications with mixed substances abuse. That was followed by combination of opiates and barbiturates in the group of patient identified positively as two or more substance abuse in the body fluids. Tramal and benzodiazepines were the most detected drugs responsible for acute intoxications between drug abusers. Acute intoxicated ethanol abusers aged from 30-49 years and were the oldest group compared to narcotics and drug abusers (20-29 years) and to organic solvent dependent patient (15-19 years).

The aim of the study was to evaluate the number and the course of acute pesticides poisoning treated in the Department of Clinical Toxicology in 1986-1995. During that period 264 cases (189 men and 75 women) of acute pesticides poisoning were treated. Suicidal oral ingestion followed by inhalation and dermal exposure was the most common cause of acute intoxication. Organophosphates and carbamates were the most common cause of acute intoxication. Poisonings with dipyridyls and sulfonylurea derivatives are relatively rare. The highest number of poisonings was noted in age group 30-39 years. In 37% of the total analysed cases the co-ingestion of ethanol was noted. As organophosphorous compounds were the most common cause of acute pesticides poisoning, the gastric lavage + intensive care treatment + specific and non-specific antidotes were the most common therapeutic management. Duration of hospitalisation was dependent on the kind of pesticide. The longest hospitalisation required the patients poisoned with organophosphates. A full recovery was noted in 57.6% of poisoned patients. 34.1% of patients suffered different organ injury mostly from respiratory and central nervous system. 22 (8.3%) the fatal cases were noted in analysed period.
