Poisoning deaths in Poland: Types and frequencies reported in Lódz, Kraków, Sosnowiec, Gdansk, Wroclaw and Poznan during 2009-2013.

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 - Lódz, Kraków, Sosnowiec, Gdansk, Wroclaw and Poznan. 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.

[Evaluation of chemical compounds acute poisoning risk among Kraków inhabitants in 1966, 1983 and 2015].

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.

[Poisonings with paracetamol, salicylates and dextromethorphan ­ problem evaluation based on data from Toxicological Laboratory and Poison Information Center in Krakow in 2010-2015].

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 assessment of factors affecting acute ethanol poisonings clinical status in 1974-1975, 1984-1985 and 2011-2013]. / Ocena czynników wplywajacych na obraz kliniczny w ostrym zatruciu alkoholem etylowym w latach 1974-1975, 1984-1985 i 2011-2013.

UNLABELLED: The aim of the study was an evaluation of clinical factors affecting relationship between ethanol concentration and clinical status in case of acute ethanol poisoning in the 70s and the 80s of the 20th century and 2011-2013 y. Ethanol blood concentration was a criterion of ethanol dose, grade of coma was a decisive factor of toxic effect. MATERIAL AND METHODS: 112 patients treated at the Department of Clinical Toxicology Jagiellonian University Medical College in 1974-1975 y, 232 treated in 1984-1985 y and 663 treated in 2011-2013 y because of acute ethanol poisoning were analyzed. The degree of coma was evaluated according to Matthew's scale. Ethanol plasma concentration in each case was measured. RESULTS: The lowest ethanol blood concentrations in the youngest (<19 y) and the oldest (>60 y) groups were noted also the highest in group of adults (30-49 y). The three-gradual relationship between ethanol plasma level and degree of toxic coma was distinguished. However, the average of ethanol blood concentration were statistically significant in every degree of coma in 2011-2013 y. A statistically significant increase in number of patients in 0 coma grade with severe withdrawal symptoms, alcohol psychosis or epilepsy were noted, also decrease of patient in IV degree of coma. CONCLUSIONS: The increase ethanol tolerance in the group of acute ethanol poisoned patients shows their ethanol addiction.

[Children and adolescents toxic exposure in 2010-2012--data of Poison Information Centre and Laboratory of Analytical Toxicology and Drug Monitoring Jagiellonian University Medical College]. / Narazenie na substancje toksyczne wsród dzieci i mlodocianych w latach 2010-2012 w materiale Osrodka Informacji Toksykologicznej oraz Pracowni Toksykologii Analitycznej i Terapii Monitorowanej Katedry Toksykologii Klinicznej i Chorób Srodowiskowych UJ CM.

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.

[Therapeutic misuses as a reason of telephone inquiries to Poison Information Centre of the Jagiellonian University Medical College in 2012]. / Bledy terapeutyczne jako powód konsultacji z Osrodkiem Informacji Toksykologicznej UJ CM w roku 2012.

The aim of the study was the analysis of exposure due to therapeutic mi. suse registered in Poison Information Centre in 2012. Of all 3084 telephone inquiries 87 were related to therapeutic misuse. The equal gender proportion were noted. More than 50% of calls registered were taken from a lay public. A most common therapeutic misuse was administration of medicine dose higher than recommended, to children of 1-6 y interval and younger, mostly by parents.

[Clinical practice guidelines in dextromethorphan poisoning pre-hospital management]. / Wytyczne postepowania w przypadku zatrucia dekstrometorfanem - postepowanie przedszpitalne.

Guideline for out - of Hospital triage and initial management of patients with suspected ingestion of dextromethorphan is presented in the study. The guideline was created by the American Association of Control Centers to assist poison center personnel while dealing with poison information service.

[Over-the-counter Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) in the material of Poison Information Centre]. / Niesteroidowe leki przeciwzapalne (NLPZ) dostepne bez recepty w materiale Osrodka Informacji Toksykologicznej.

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.

[Designer drugs--diagnostic, psychological and low aspects of problem]. / Dopalacze jako problem diagnostyczny, psychologiczny i prawny.

Designer drugs used often by teenagers have simulative, relaxing, hallucinogenic and psychedelic properties. The biological action, addictive potential, diagnostic problems and low regulations related to designer drugs are presented in the study.

Frequency and pattern of poisoning in adult and adolescent Kraków population in 2003 and 1983.

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.

[The role of poison information center in the health service structures]. / Miejsce Osrodka informacji Toksykologicznej w strukturach sluzby zdrowia.

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.

Toxic exposure of children in 2004--telephone service of toxicology.

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.

Prescription and over-the-counter medication in deliberate self-poisoning and accidental overdosing--preliminary study.

186 case records of patients who overdosed pharmaceuticals (confirmed by toxicological lab analysis) hospitalized at the Department of Clinical Toxicology during three months of 2000 were analyzed for age, sex, type of medication, reason for poisoning (intentional or accidental overdosing). Patients poisoned with prescription medication (Rx group) were compared with those who overdosed nonprescription (OTC-group) medications (alone or combined with Rx). Relative frequency of medication drug poisoning was highest in the 40-49 age group (28.5%) and was followed by the group of young adults (20-29 years; 24.2%). The lowest frequency (2.2%) was noted in the 60-69 age group. Of 186 cases analyzed, in 163 (87.6%) prescription medication (Rx) and in 23 (12.4%) OTC alone or co-ingested with Rx were involved (chi2 = 63.9; p < 0.001). The Rx and OTC groups were not significantly different as to reason for poisoning (chi2 = 0.7; p = 0.792) with significant overrepresentation of deliberate ingestion in both the group analysed (chi2 = 114.39; p < 0.001 for Rx, and chi2 = 13.49; p = 0.002 for OTC). Most adults attempting suicide used Rx with the highest incidence in the 40-49 age group (31.1%). Adolescents (14-19 years) with female over-representation ingested rather OTC pharmaceuticals (40.9%). Acetaminophen (alone or combined with benzodiazepines or/and ethanol) and nonsteroidal anti-inflammatory drugs (NSAIDs) were the most common OTC medications used for deliberate self-poisoning.

[Dangerous aquaria]. / Niebezpieczne akwaria.

World trends for a home breeding of exotic freshwater and marine fishes did not miss Poland. There are almost all species of aquarium fishes available in Polish pet shops, but there is not enough information about threat given to customers. In some fish, there are masses of one-cell glands, mainly serous, in the proximity of the spines. In others, those one-cell glands may be grouped in larger aggregates of cells called venom glands, that may form organs resembling multicellular glands of terrestrial animals. They are usually located around the spines or hard rays of the fins. Even if covered with a connective tissue sheath, the aggregates of the venom cells do not have any common outlet; they are not, therefore, proper multicellular glands. The venom glands of the catfish are covered with a thin sheath and they release their contents when the fin ray is pressed. Spines are derived from fin rays. When the spine penetrates the body of its prey, it presses its base against the cells, squashes them and squeezes the venomous contents into the wound. Catfish, lionfish and stonefish have the venom glands producing secretion which could be dangerous. The eels and morays blood is also dangerous, as well as slime of reduced squamae. Poison information centers noted several cases of fishes' stings in Poland.

[Poisonous animals registration in Poland]. / Rejestracja zwierzat jadowitych w Polsce.

The Act on Nature Conservation of 16.04.2004 (Official Journal, 2004, No 92, item 880) imposes on private individuals the duty to register some animals. The data collected by Kraków municipal authorities and delivered to the Poison Information Centre (Colleglum Medicum, Jagiellonian University) indicate that there are following species in private hands in the city and its surroundings: 11 individuals of Naja naja, 2--Hydrodynates gigas and 55-- Dendrobates spp. According to these information the employees of the PIC elaborated the advice on the treatment of specific animals' poisoning. In the period May 2003 - May 2004 (before the above Act came into force) there were 143 individuals from Brachypelma genus and 3 scorpions (Pandinus imperator) registered in Krakow. These species produce venoms which take local effect. According to art. 64 (1) of the above Act it is compulsory to register amphibians, reptiles, birds and mammals. However, it would be desirable to introduce the duty to register also dangerous species of invertebrates and fishes. It would provide the complete list of poisonous animals kept in private hands. Thus, it would be possible to estimate any possible threats and to elaborate adequate treatment in case of specific animals' poisoning.

[Cardiotoxic plants]. / Rosliny kardiotoksyczne.

In statistics from Poison Information Center in Kraków plant poisonings comprise 2% of the total registered poisonings. In toxicology cardiac glycosides poisonings existing in common foxglove plant, lilies of the valley, oleander are essential. Species of cardiotoxic plants which may cause a danger in Poland are presented in the research. The toxic mechanisms of cardiac glycosides are specified.

Chemical poisonings among Kraków inhabitants in 1972 and 2002.

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 frequency of suicide attempts depending on gender and the age structure]. / Czestosc prób samobójczych w zaleznosci od plci i struktury wiekowej.

Sex and the age structure have been for decades the crucial factors determining the dimensions of suicide. In the literature of the subject, it is possible to find different interpretations concerning the widely known facts of larger effectiveness of suicide among males. Females, on the other hand, exhibit suicidal behaviour and suicide attempts several times bigger than the number of completed suicides. In comparison with wide literature dealing with the problematic of completed suicide, the number of publications concerning suicide attempts is, both in foreign and in Polish literature rather scarce. That is why the present authors have undertaken the analysis of suicide attempts by subjects hospitalized in the Department of Clinical Toxicology Jagiellonian University College of Medicine in Krakow in the years 2000-2002. On the basis of the medical documentation, 2757 cases of attempted suicide through self-intoxication by subjects undergoing treatment in the toxicological department. In the period concerned, the number of hospitalizations after suicide attempts increased from 856 cases in the year 2000 to 971 cases in 2001, and subsequently slightly decreased to 930 cases in 2002. The highest indicator of suicide attempts through self-intoxication has been observed among adolescents and young adults. In the absolute values, within the span of the years in question, there is a substantial predominance of suicide attempts undertaken by adults ranging in age from 20 and 50. On the contrary, in the oldest age group (over 60), the number of suicide attempts through self-intoxication was in the years concerned the lowest. In contrast with completed suicide, where the proportion of males to females is 4:1, in the group examined, females constituted 50% of subjects after suicide attempts. The number of females after suicide attempts in the consecutive years analysed was higher among adolescents and young women under 30. Despite drawbacks in data gathering, there is convincing testimony indicating that suicide is the result of number of complex risk factors. Sex and the age structure belong to non-modifiable factors, and thus emphasis should be put on the importance of the gathering of relevant data and on further research into the factor of sex and age structure in suicide attempts and completed suicide.

[Fluctuations and seasonality in suicidal attempts]. / Fluktuacje i sezonowosc prób samobójczych.

The aim of the study was to analyze seasonality and temporal fluctuations in suicide attempts by persons living in Krakow and hospitalized in the Department of Clinical Toxicology CMUJ in the years 2000-2002. The research focussed on the frequency of suicide attempts in relation to the time of the day, day of the week, and month of the year. Temporal fluctuations in the frequency of suicide attempts have been assessed on the basis of the data from medical documentation concerning 2757 suicide attempts by individuals ranging in age from 14 to 90 years. The group consisted of 1607 females and 1150 males. According to the results of the research, seasonality and temporal fluctuations in the frequency of suicide attempts is different for males and females. In the case of the males examined, no dependence between the frequency of suicide attempts and a particular month or season has been observed. In the case of females, on the contrary, the data indicate the existence of a seasonal pattern with the peak in the spring (or early part of the summer), and in the autumn--in October and November. In males, the peak day for attempted suicide was Monday, whereas in females--Sunday and Monday. As regards the time of the day, both the results of the present research and data collected by WHO/EURO indicate that suicide attempts occurred most frequently in the evening, late in the evening or in the early part the night. In conclusion, it has been emphasized that the majority of suicide attempts, especially by females, occurs late in the evening or early in the night. This finding seems to be of particular importance for suicide prevention--it can contribute to the increase in the effectiveness of the organization of work in the Crisis Intervention Centres and make therapists and patients' families aware of the existence of periods of an increased suicide risk. The research has been conducted owing to the cooperation between the department of Clinical Toxicology, CMUJ and the Department of Adult Clinical Psychiatry, CMUJ in Kraków. The results obtained, together with the results of the research conducted by the centres participating in WHO/EURO are vital for suicide prevention and treatment.
