Opium poisoning in modern times. An overview.

Opium is a substance extracted from Papaver somniferum L that is chronically abused specially in the traditional production regions. Reports on opium poisoning has largely disappeared from the occidental literature on drug problems but recent scientific articles show cases of death related to opium in industrialized countries. This fact led us to consider the interest of knowing the state of the art of acute opium intoxication in modern times. This work shows a compilation of these uncommon cases occurred in different settings and circumstances. Data were obtained by a computer assisted search of the literature using the key words "opium poisoning", "poppy", "poppy seeds", and "papaver somniferum" in PubMed, accompanied by a hand search of the reference lists of all articles for any relevant studies not included in the database. In addition, Google Scholar, government reports, and cases adequately documented on websites were reviewed. Type 1 cases, Accidental opium intoxications when it is used as a recreational drug: Reported cases came mainly from industrialized countries. They were mostly male with a range age of 17-64 years. Many had antecedents of alcoholism or drug abuse and opium tea was used as a substitute of heroin. Rachacha has caused poisonings in France and has been detected in a stash in Spain. Toxicological analysis was documented in forensic cases. The danger of this renewed interest in opium is exemplified in that many of the poisoning cases resulted in fatalities. Type 2 cases, Accidental opium intoxications in children or adults when it used as folk remedy: Pediatric intoxication after the use of opium as folk remedy are mainly published in traditional opium-producing areas with a long history of use or ethnic communities in England or USA. Addiction to opium was common among relatives. Type 3 cases, Opium intoxications with poppy seeds consumed as food: Due to excessive consumption of opium seeds as food, sporadic cases of mild toxicity had been reported and morphine contents were documented. Type 4 cases: Accidental opium intoxications when using the abdominal or pelvic cavity for concealing the drug: Accidental opium body packer intoxications are seen in patients who traveled from illegal opium areas of production. Type 5 cases: Suicides by opium: Opium was a prevalent agent among cases of suicides in Iran but data are scarce.

Death in a legal poppy field in Spain.

Opium is a substance extracted from Papaver somniferum L. Opium latex contains morphine, codeine, and thebaine and non-analgesic alkaloids such as papaverine and noscapine. In Spain opium growing is allowed only for scientific or pharmaceutical purposes and harvest is supervised by the Spanish Health Ministry. This work describes a sudden fatality involving opium consumption in a legal poppy field. The toxicological and autopsy findings, previous disease, paraphernalia, and scenario are discussed in order to clarify cause and manner of death. A 32-year-old white caucasian male was found unresponsive in a legal poppy field in the South of Spain. The emergency medical services responded to the scene where he was pronounced dead. The friends explained that the deceased had presented with about 30min of convulsions; in spite of trying to keep his airway tract open they noted that "he stayed airless". According to them the victim suffered from epilepsy. Tools found beside his body consisted of plain wood sticks with a blade razor, a fabric handle, and paper. A comprehensive toxicological screening for abuse and psychoactive drugs was performed in the deceased samples. This included ethanol and volatile analysis by HS-GC-FID in peripheral blood and urine, enzyme immunoassay in urine by CEDIA, and a basic drug screening in all samples (including paraphernalia) by GC-MS using modes full scan for screening/confirmation and selected ion monitoring for quantitation. The peripheral blood, urine, vitreous, and gastric content contained the following concentrations of opiates expressed in mg/L (gastric content additionally also expressed in mg total): 0.10, 7.12, 0.23, and 14.80 (2.81mg total) of thebaine, 0.13, 4.50, 0.13, and 6.60 (1.25mg total) of morphine (free), 0.48, 0.88, 0.17, and 1.50 (0.28mg total) of codeine. These tree opiates were also detected in the tools (paraphernalia) used by the deceased for opium consumption. Other toxicological findings were metabolites of cocaine and cannabis. Apparently the victim stole poppy capsules and ingested an unknown quantity of the latex with the goal to obtain euphoric effects. The cause of death was considered poly-drug toxicity with a preponderant role of thebaine and morphine. In addition, the epileptic condition of the deceased could have played a role. As far as we know, there are no previous reports of fatalities occurring in legal poppy fields.

Acute adult and adolescent poisoning in Tehran, Iran; the epidemiologic trend between 2006 and 2011.

BACKGROUND: The aim of this study was to determine the frequency of each poisoning and its related death in our center as a sample of Tehran in six consecutive years (2006 to 2011). METHODS: All poisoned children and adults referring to Loghman-Hakim hospital poison center and hospitalized in the study period were enrolled and evaluated. RESULTS: In 108,265 patients, the most common causes of poisoning were anti-epileptics and sedative-hypnotics (22.3%). The most common causes of death were pesticides (24.84%) and narcotics (24.75%). In drugs of abuse, opium was more prevalent in the early period of the study but was replaced by methadone later. CONCLUSION: It seems that national policies for drug control and prevention of suicide have not been efficient enough. We expect to see Iran in the first 50 countries with regard to suicide and to maintain the first place in narcotic abuse if enough attention is not provided.

[Biochemical diagnostics of fatal opium intoxication].

Biochemical diagnostics of fatal opium intoxication remains a topical problem in forensic medical science and practice. We investigated materials obtained in the course of forensic medical expertise of the cases of fatal opium intoxication. The study revealed significant differences between myoglobin levels in blood, urine, myocardium, and skeletal muscles. The proposed approach to biochemical diagnostics of fatal opium intoxication enhances the accuracy and the level of evidence of expert conclusions.

Prehospital treatment of opioid overdose in Copenhagen--is it safe to discharge on-scene?

INTRODUCTION: In the prehospital setting opioid overdose is often treated with naloxone. In our physician-based medical emergency care unit (MECU) we have adopted a discharge-on-scene policy, where patients are released on scene if no residual signs of opioid intoxication are found after treatment. The aim of this study was to describe our experience with the discharge-on-scene policy used during a 10-year-period with focus on the frequency of rebound opioid toxicity. METHODS: Data were prospectively recorded in our MECU database and we reviewed all cases of opioid overdose between 1994 and 2003. The MECU database was cross-referenced with the Central Personal Registry. For patients who died within 48 h of MECU contact we reviewed the forensic autopsy reports to establish whether rebound opioid toxicity was likely. RESULTS: We found 4762 cases of acute opioid overdose. In 3245 cases positive identification was obtained. Over this ten year period fourteen patients who were released on-scene after having been treated with naloxone died within 48 h, but only in 3 of these we found a rebound opioid toxicity to be the likely cause of death, corresponding to 0.13% of those 2241 released on scene who were identified. CONCLUSION: Prehospital discharge-on-scene after naloxone treatment is associated with a low risk of death due to rebound toxicity.

Treatment of opioid overdose in a physician-based prehospital EMS: frequency and long-term prognosis.

BACKGROUND: Prehospital treatment of opioid overdose accounts for a significant proportion of the workload of the emergency system in most major cities. Treatment consists of basic life support and administering naloxone. In our physician-manned mobile emergency care unit (MECU), most patients are released and not admitted to hospital. In this study, we aimed to assess the pattern in the number of episodes with opioid overdose treated by MECU in Copenhagen during a 10-year period and to investigate risk factors for mortality of these patients beyond the initial contact. METHODS: Data were collected prospectively in the MECU database covering all cases of opioid overdose in a 10-year period between 1994 and 2003. The pattern in the number of opioid overdose was analysed in Poisson regression models, and mortality was analysed in Kaplan-Meier plots and in Cox regression models. RESULTS: A total of 4762 episodes of opioid overdose were recorded. Patients were identified in 3245 of these episodes. The annual number of episodes decreased significantly over the data-collection period: from 639 overdoses out of 4520 (14.1%) patients treated in 1994 to 311 out of 7263 patients treated (4.3%) in 2003. A total of 352 patients had cardiac arrest at the scene. The MECU released 2246 patients (69.3%) after treatment, while 675 (20.8%) were admitted to hospital and 322 (9.9%) died. Long-term prognosis was poor with 14% mortality at 1 year. Long-term mortality was significantly related to increasing age, time of the year and if the patient had previous episodes of opioid overdose. CONCLUSIONS: There has been a significant decrease in the number of opioid overdoses during this 10-year-period. Long-term mortality is high in these patients and highest in those with advanced age and numerous episodes of opioid overdose.

Hallmarks of opium poisoning in infants and toddlers.

Accidental opium intoxication in children is an extremely dangerous poisoning if it remains undiagnosed and untreated. The classic triad of miosis, decreased level of consciousness and bradypnea, which are the hallmarks of opiate intoxication, are used for the diagnosis of opium poisoning in adults and children. Little attention has been paid to the signs of opium intoxication in children and no published study has explored the frequency of hallmarks of this type of poisoning in the paediatric population. We conducted a study in order to evaluate the prevalence of major signs of opium poisoning in infants and toddlers. In this study, a total of 228 infants and 82 toddlers who had been admitted to Loghman Hakim Hospital as a result of opium poisoning between 2001 and 2009 were evaluated, retrospectively. The most usual sign of opium poisoning was miosis (90%) followed by a decreased level of consciousness (88.4%), bradypnea (28.4%) and seizure (10.3%). The prevalence of the triad of miosis, bradypnea and a decreased level of consciousness was 25.2%. Miosis in association with decreased level of consciousness was detected in 82.6% of our patients. Bradypnea was present in 74 infants and 14 toddlers, which shows a statistically significant difference (P = 0.01). The mean age and weight of the patients with bradypnea were significantly less than those without bradypnea (P = 0.008 and P = 0.0001, respectively). Bradypnea and seizure were significantly more common in females (36.7% versus 26%; P = 0.05 and 15.2% versus 6.5%; P = 0.01, respectively). Miosis in association with a decreased level of consciousness is the most useful indicator of opium poisoning in infants and toddlers. Furthermore, seizure is a more common feature of this type of poisoning in infants, especially in those who are less than 1 month old.

Opium as a fatal substance.

OBJECTIVE: Poisoning does the most serious damages in pediatrics. In the northeast of Iran (Golestan province), opium is used widely for symptomatic therapy of routine illnesses in young children by parents. In the present study, opium toxicity was assessed in young children referred to pediatric centers in our area. METHODS: This survey was done as a prospective cross-sectional study. At first, a pilot study was undertaken to estimate the condition of opium intoxicated children and evaluate the validity of questionnaire. We collected data in collaboration with committee of Adverse Drug Reactions (ADR) in Golestan Province. All members of ADR committee in pediatric centers were trained to complete questionnaires in referred or admitted children under-5-year. Data was entered into computer and analyzed by Chi-square and Fisher exact test. RESULTS: In this survey, 67 opium-intoxicated children were recruited. Minimum age of the cases was 6 days and maximum 5-year. Uneducated mothers, in most cases, gave opium to the child. Most of them were from the low socio-economic level. Ethnic was disparity was observed. Four deaths occurred. CONCLUSION: As the results showed, opioids are dangerous in pediatric population, especially under 5-year. Respiratory depression, bradypnea, coma and death are the serious outcomes of opium toxicity in pediatrics. Such a practice of unrestricted use of opium contributes to children mortality and so it is essential to launch educational programs.

Toxins.

Exposures to toxins are prevalent, frequently complicate surgical emergencies, and impact critical care. A fundamental understanding of pathophysiologic principles and management strategies is essential for the anesthesiologist frequently responsible for the acute care of patients who have toxicologic exposures. Given their pervasiveness and ability to confound the clinical presentations in the perioperative or intensive care setting, substances of abuse and asphyxiants warrant particular attention and a high degree of vigilance.

The insulin pump as murder weapon: a case report.

Microprocessor-controlled insulin pumps designed for continuous delivery of short-acting insulin analogs into subcutaneous tissues offer several important potential benefits for diabetic patients. The delivery of other substances using these systems is technically feasible. We present a case of homicide involving lethal doses of etomidate and atracurium injected via the victim's insulin pump. This unique situation could be encountered by homicide investigators more frequently as the popularity of these systems continues to grow.

Patient-controlled analgesia. A serious incident.

A patient received a massive overdose of papaveretum intravenously (estimated to be 180 mg) when the glass syringe of a patient-controlled analgesia machine disengaged from the drive mechanism. She was successfully resuscitated. The pump, on loan from the supplier, had passed a brief evaluation by the infusion pump test house designated by the Medical Devices Directorate of the Department of Health; it has since been withdrawn. It is recommended that patient-controlled analgesia equipment should be placed at or below patient heart level. The Department of Health is called on to institute a full, independent evaluation scheme for patient-controlled analgesia equipment.

Fatal intoxications in Denmark following intake of morphine from opium poppies.

In Denmark it is legal to grow opium poppies for the production of poppy seeds and until 1986 for decoration purposes, too. Danish poppy capsules contain 0.3-5 mg morphine per capsule and the content of morphine in opium exuded from the capsules may amount to 24%. This has resulted in misuse as both fresh and dried poppy capsules have been used for the production of "opium tea". During the period 1982-1985, seven casualties occurred among drug addicts in Denmark which were solely or partly caused by these opium poppies.
