ABSTRACT
OBJECTIVE: To describe an outbreak of lead poisoning among opium users in the Islamic Republic of Iran and estimate the number of affected people in the country. METHODS: We used data from the country's largest poison treatment centre to illustrate the epidemiology of an outbreak of lead poisoning in oral opium users. We describe the government's referral and treatment guidelines in response to the outbreak. Based on the number of individuals treated and previous studies on the prevalence of oral opium use we estimated the total number of people at risk of lead-contaminated opium nationwide. FINDINGS: In February 2016, we noticed a steep increase in the numbers of oral opium users referred to our poison treatment centre with abdominal pain, anaemia and constipation. Numbers peaked in June 2016 but the outbreak was ongoing in August 2017. The mean blood lead level in a sample of 80 patients was 140.3 µg/dL (standard deviation: 122.6). Analysis of an illegal opium sample showed 3.55 mg lead in 1 g opium. Treatment was exposure reduction with opioid substitutes and laxatives, or chelation therapy if indicated. Over 7 months, 4294 poison cases were seen at main referral hospitals in Tehran out of an estimated 31 914 oral opium users in the city. We estimate more than 260 000 out of 773â¯800 users nationwide remain untreated and at risk of poisoning. CONCLUSION: Lead-contaminated opium and heroin that has transited through the Iranian markets is a global risk and highlights a need for better monitoring of illegal drug supplies.

The Golden Crescent region of South Asia-comprising Afghanistan, Iran, and Pakistan-is a principal global site for opium production and distribution. Over the past few decades, war, terrorism, and a shifting political landscape have facilitated an active heroin trade throughout the region. Protracted conflict has exacerbated already dire socio-economic conditions and political strife within the region and contributed to a consequent rise in opiate trafficking and addiction among the region's inhabitants. The worsening epidemic of injection drug use has paralleled the rising incidence of HIV and other blood-borne infections in the region and drawn attention to the broader implications of the growing opiate trade in the Golden Crescent. The first step in addressing drug use is to recognize that it is not a character flaw but a form of mental illness, hence warranting humane treatment of drug users. It is also recommended that the governments of the Golden Crescent countries encourage substitution of opium with licit crops and raise awareness among the general public about the perils of opium use.

BACKGROUND: The aim of this study is to present our long-term clinical experience in describing a clinical picture of Buerger's disease in our region. MATERIALS AND METHODS: In a retrospective study, files of 225 patients who were admitted to the hospital with diagnosis of thromboangiitis obliterans in a 10 year period from 2000 to 2010 were reviewed. All data including demographic, signs and symptoms, history of previous illness, history of smoking, medications, laboratory tests, angiography, and details of surgical operation were obtained. RESULTS: A total of 222 (98.7%) and 3 (1.3%) of patients were male and female, respectively. Average age of hospitalized patients was 40.7 ± 8.5 (20-62) years. A total of 200 patients (88.9%) were active cigarette smokers while 168 (74.7%) of them were opium addicts. The most prevalent symptoms were chronic ulcers (80%) and claudication (63.6%). Minor and major amputation was required in 113 (50.2%) and 41 (18.4%) patients, respectively. Amputation was carried out on the lower limb (80%), upper limb (4.1%), or on both (15.1%). Also, four patients underwent revascularization through surgical bypass procedures. CONCLUSIONS: The diagnosis and treatment of Buerger's Disease is still a challenge in those communities where the disease is endemic. Therefore, identifying the natural course of the disease can play a pivotal role in the diagnosis and treatment of these patients.

An estimated 16·5 million people worldwide illicitly use opiates, of whom 4 million use raw opium. We did a systematic review to investigate the association between opium use and cancer incidence and mortality. Opium use was associated with an increased risk of cancers of the oesophagus, stomach, larynx, lung, and urinary bladder. Although the present evidence suggests that these associations are possibly causal, further epidemiological studies (particularly prospective studies that collect detailed data about lifetime opium use and control for a broad range of potential confounders) are needed.

BACKGROUND: Lung cancer is the leading cause of cancer-related death worldwide, and half of all incident lung cancers are believed to occur in the developing countries, including Iran. OBJECTIVE: We investigated the association of opium with the risk of lung cancer in a case-control study. METHODS: We enrolled 242 cases and 484 matched controls in this study. A questionnaire was developed, containing questions on basic demographic characteristics, as well as lifelong history of smoking cigarettes, exposure to passive smoking, opium use and alcohol consumption. For smoking cigarettes and opium and also oral opium intake frequency, duration and cumulative use were categorized into three groups: no use, low use and high use. Conditional logistic regression was used to calculate the odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Multivariate analysis in men showed that after adjusting for the effect of ethnicity, education and pack years of smoking cigarettes, smoking opium remained as a significant independent risk factor with an OR of 3.1 (95% CI 1.2-8.1). In addition, concomitant heavy smoking of cigarettes and opium dramatically increased the risk of lung cancer to an OR of 35.0 (95% CI 11.4-107.9). CONCLUSION: This study demonstrated that smoking opium is associated with a high risk of lung cancer as an independent risk factor.

The spreading of opium use poses new health related concerns. In some areas of Asia its use is believed to protect from cardiovascular disorders, such as coronary artery disease (CAD). However, whether opium use has an association with CAD is unclear. We aimed to investigate the association between non-medical opium use and CAD. We set up a case-control analysis, i.e., the Milano-Iran (MIran) study by enrolling consecutive young patients who underwent a coronary angiography at the Tehran Heart Center, between 2004 and 2011. Incident cases with CAD were contrasted with controls for opium use. Relative risks were calculated in terms of odds ratios (ORs) by logistic regression models adjusted for age, sex, cigarette smoking, body mass index, hypertension, hyperlipidaemia, and diabetes. Interaction analyses were performed between opium and major cardiovascular risk factors. 1011 patients with CAD (mean age 43.6 years) and 2002 controls (mean age 54.3 years) were included in the study. Habitual opium users had a 3.8-fold increased risk of CAD (95%CI 2.4-6.2) compared with non-users. The association was strongest for men, with a fully adjusted OR of 5.5 (95%CI 3.0-9.9). No interaction was observed for the combination of opium addiction and hypertension, or diabetes, but an excess in risk was found in opium users with hyperlipidaemia (OR 16.8, 95%CI 8.9-31.7, expected OR 12.2), suggesting supra-additive interaction. In conclusion, despite common beliefs, we showed that non-medical opium use is associated with an increased risk of CAD, even when other cardiovascular risk factors are taken into account.

Background: The prevalence of opium addiction in Iran is high probably due to the belief that opium has preventive effects against cardiovascular diseases. In the second phase of Kerman coronary artery disease risk factors study, the prevalence, incidence rate, and the association between opium use and other coronary artery disease risk factors (CADRFs) were assessed. Methods: In a cross-sectional study (2014-2018), 9996 inhabitants of Kerman, southeastern Iran, aged 15-80 years were recruited to the study. After taking fasting blood samples, the participants were examined or interviewed for demographic data and CADRFs, including opium use. The participants were categorized into "never", "occasional", and "dependent" users. The association between opium use and CADRFs was assessed with adjusted regression analysis (Stata v.11 software). Results: The overall prevalence of opium consumption was lower than that of five years earlier (P<0.01). The prevalence was currently higher in men than women and decreased in men between the two phases (P<0.001). There was a positive correlation between opium use and depression (P<0.001), anxiety (P<0.05), and a negative association with the level of physical activity (P<0.001). The five-year incident rate of dependent and occasional opium use was 4.2 and 3.9 persons/100 person-years, respectively. The incidence of opium use was higher in diabetic, hypertensive, depressed, anxious, and obese subjects. Conclusion: The study did not demonstrate any protective effects of opium on CADRFs. Considering the higher rate of opium use in subjects with hypertension, diabetes, obesity, and psychological disorders, the health authorities should implement educational programs to warn and correct the unsafe belief.

CONTEXT: Heavy metals, including thallium and lead, are introduced to illicit drug users' body as a result of using drugs such as cocaine and heroin. OBJECTIVE: This study aimed to determine urine, blood, and hair thallium (Tl) concentrations in illicit opioid users along with the relevant clinical signs and symptoms consistent with thallotoxicosis and to compare them with the corresponding variables in the control non-opioid user group. MATERIALS AND METHODS: This case-control study was conducted on 50 illicit opioid users who had abused opioids continuously for more than a year, referred to Amirie Drug Abuse Treatment Clinic in Kashan, Iran. The control group included 50 non-opioid users. Thallium concentrations in urine, blood, and hair were assessed in both groups (n = 100) using electrothermal (graphite furnace) atomic absorption spectrometry (ET AAS, GF AAS). RESULTS: In the studied group, the median (interquartile range) concentrations of thallium in urine, blood, and hair were 54.8 ± 79.9 µg/L, 14.5 ± 11.1 µg/L, and 5.4 ± 3.7 µg/g, respectively; these values were 4.8 ± 5.2 µg/L, 2.5 ± 2.4 µg/L, and 1.4 ± 1.1 µg/g, respectively, in the control group. There were significant differences in urine, blood, and hair thallium concentrations between the study group and the control group (p < 0.001). There were significant correlations between duration of illicit opioid use and urine thallium concentrations (r = 0.394, p = 0.005) and hair thallium concentrations (r = 0.293, p = 0.039), but not with blood thallium concentrations (r = 0.246, p = 0.085). Urine and blood thallium concentrations of illicit opioid users with clinical signs and symptoms consistent with thallotoxicosis of weakness (p = 0.01), depression (p = 0.03), and headache (p = 0.03) were higher than users without these problems. DISCUSSION AND CONCLUSION: The results of the study showed that thallium concentrations in urine, blood, and hair in illicit opioid users were significantly higher than the comparable concentrations in the control group. This can be due to the use of illicit opioids adulterated with thallium. Also, this study showed long-term illicit opioid use may lead to thallium exposure. In addition, cigarette smoking was associated with increased thallium exposure.

INTRODUCTION: An earthquake measuring 6.6 on the Richter scale on 23 December 2003 devastated the city of Bam in southeastern Iran. During the response and recovery phases, considerable shortcomings were discovered. The dire situation in the affected area, a variety of urgently required interventions, and the large number of aid organizations involved brought about difficulties in management, coordination, and communication among authorities and aid organizations. This article highlights flaws in management in the various aspects of this disaster in order to assess what was done, and what should be done to overcome these shortcomings in future disasters. METHODS: A retrospective review of the various aspects of management related to the Bam disaster was done via the assessment of files, multi-center studies, governmental data, and available literature from 2003-2008. RESULTS: A review of the available data relevant to search and rescue operations and short-term aid provision revealed flaws in different aspects of disaster management including personnel, the transfer of the injured, availability medical supplies, treatment planning, problems concerning the composition of treatment forces dispatched to the region, distribution of tasks among treatment workers, transferring of equipment, availability of facilities, and lack of coordination among the organizations responsible for the management of the disaster. Most of the aforementioned issues have been addressed. CONCLUSIONS: A comprehensive disaster management plan must not be limited only to the response phase, but rather must include: preparedness, recovery with optimal legislation and budgeting, improvement of healthcare facilities, and organized communication channels between the different governmental departments. This important issue has been addressed, and a disaster management organization under the supervision of the President has been established, developing a national search and rescue strategy and protocol for unified managerial organization, an alert system, an international disaster command system (under which search and rescue and emergency medical service teams can be deployed, increasing the efficacy and coordination of the arrival of foreign teams and the construction field hospitals), and developing a flowchart to coordinate international agencies and the domestic authorities in charge. Continuous education, training of the general population, conducting periodic exercise drills, and provision for prepared task force mobilization in disaster management all are important aspects of the management of disasters due to natural hazards.

OBJECTIVE: Several factors can influence the quality of life in patients with coronary artery disease (CAD). The goal of this research was to measure quality of life in opium-addicted patients with CAD in order to assess the effect of CAD risk factors on their quality of life. METHOD: The WHOQOL-BREF questionnaire was completed through interviews with 275 patients who underwent isolated coronary artery bypass surgery in Tehran Heart Centre between May and September 2006. RESULTS: No significant differences were found in the mean scores of the four domains of quality of life between the addicted and non-addicted patients. Furthermore, the evaluation of QOL in the groups with CAD risk factors showed that the mean QOL domains were statistically similar between opium addicted and non-opium addicted patients. In the addicted group, men had a higher psychological health score than women. A previous history of myocardial infarction reduced the psychological score in this group. Also, in the addicted patients with a history of diabetes mellitus, social functioning was better than that of the non-diabetics. CONCLUSIONS: The different domains of quality of life in our opium-addicted and non-addicted patients with CAD were similar; and among all the major risk factors for coronary artery disease, only female gender and a previous history of myocardial infarction could influence quality of life in the opium-addicted patients.

BACKGROUND: Measuring the amount of opium use is a challenge in epidemiologic studies. Self-report of amount of opium use at each consumption, widely used in the literature, usually fails to provide a good estimate. The purpose of this study is to systematically study the perceived weight units of reported opium use in Iran, and compare them to the standardized units of weight measurement. METHODS: An exploratory descriptive study was conducted in six major cities of Iran. Study participants were interviewed and asked to use a Play-Doh-like material to demonstrate the amount of opium they use. To obtain an estimate of the weight of the material used, we multiplied the volume by the density of the opium product. We experimentally determined the density of the commonly used opium products. We used medians and inter-quartile ranges (IQRs) to report the typical amount of each unit. RESULTS: A total of 108 individuals participated in this study. The most frequently reported unit was "gram"; the median perceived weight for one gram (g) of opium was 0.24 (IQR: 0.16) g. The second most commonly used unit was nokhod with a median of 0.16 (IQR: 0.16) g, followed by mesghaal and hab/habeh, which were 1.28 (IQR: 0.81) and 0.16 (IQR: 0.16) g, respectively. The median perceived weight of mesghaal and gram in the studied cities was less than the expected standardized values. CONCLUSION: In conclusion, the reported amount of opium use is highly inaccurate and unreliable, and is mainly subject to underestimation.

BACKGROUND: While data from USA and Canada demonstrate an opioid overdose epidemic, very little nation-wide European studies have been published on this topical subject. METHODS: Using a nationally representative sample of the French Claims database (>700,000 patients), the exhaustive nationwide hospital discharge database, and national mortality registry, all patients dispensed at least one prescription opioid (PO) in 2004-2017 were identified, to describe trends in PO analgesic use, shopping behaviour, opioid-related hospitalizations and deaths. Annual prevalence of PO use and shopping behaviour (≥1 day of overlapping prescriptions from ≥2 prescribers, dispensed by ≥3 pharmacies) was estimated. RESULTS: In 2004-2017, the annual prevalence of weak opioid use codeine, tramadol and opium rose by 150%, 123%, and 244%, respectively (p < 0.05). Strong opioid use increased from 0.54% to 1.1% (+104%, p < 0.05), significantly for oxycodone (+1950%). Strong opioid use in chronic noncancer pain rose by 88% (p < 0.05) and 1180% for oxycodone. Opioid shopping increased from 0.50% to 0.67% (+34%, p < 0.05), associated with higher mortality risk HR = 2.8 [95% confidence interval (CI): 1.2-6.4]. Opioid-related hospitalizations increased from 15 to 40 per 1,000,000 population (+167%, 2000-2017), and opioid-related deaths from 1.3 to 3.2 per 1,000,000 population (+146%, 2000-2015). CONCLUSIONS: This study provided a first European approach to a nationwide estimation with complete access to several national registries. In 2004-2017 in France, PO use excluding dextropropoxyphene more than doubled. The increase in oxycodone and fentanyl use, and nontrivial increasing trend in opioid-related morbidity-mortality should prompt authorities to closely monitor PO consumption in order to prevent alarming increases in opioid-related morbidity-mortality. SIGNIFICANCE: In 2004-2017, prescription opioid use in France at least doubled and oxycodone use increased particularly, associated with a nontrivial increase in opioid-related morbidity-mortality. Although giving no indication for an 'opioid epidemic,' these findings call for proper monitoring of opioid use.

BACKGROUND: Type 2 diabetes is a common disorder that is recognized as a major health problem in Iran. Diabetes is a major cause of morbidity, mortality, and economic burden to the society. Some people believe that smoking opium can reduce serum glucose and lipids in diabetes mellitus. This study was designed to compare blood glucose and lipids in opium addicts with non-addicts among patients with type 2 diabetes. METHODS: In this case, control study subjects were chosen from type 2 diabetic patients. Twenty-three males with type 2 diabetes and addicted to opium were selected as the case group, and 46 patients with no addiction to opioid drugs were chosen as control group. Blood Sugar (BS), glycated hemoglobin (HbA1C), lipids and microalbumin in urine were measured in two groups. RESULTS: Our results showed that the mean FBS and 2-hour post prandial were significantly different between two groups. (P = .04). No significant difference was observed in HbA1C, triglyceride, total cholesterol, LDL, and HDL between the two groups (P > .05). CONCLUSIONS: Our finding showed that while opium might decrease blood glucose temporarily, it had no clear and long-lasting effects on blood glucose, as it had no significant effect on HbA1c.

Opium is the latex from the opium poppy Papaver somniferum L., which humankind has utilized since ancient Mesopotamia all the way to modern times. Opium used to be surrounded in divine mystery or magic-like abilities and was given to cure a wide variety of diseases until its analgesic, antitussive, and antidiarrheal properties were understood, the resulting alkaloids were isolated, and their structure and properties unmasked. Opium went from being sold in any store front in the form of pills or tinctures with no prescription necessary for purchase or smoked in an opium den down the street, to then bringing about consumer advocacy and the right to know what is in a medication. Legislation was created to limit the prescribing and selling of medications to doctors and pharmacists as well as outlawing opium dens and smoking opium. This review focuses primarily on the uses of opium throughout history, the isolation of the principle alkaloids, and their structure elucidation.

Adulteration of drugs with poisonous substances during production or consumption has caused numerous health problems. Among contaminants that have the potential of producing poisonous effects are the heavy metals lead, arsenic and thallium that make up an important group of toxic substances. The emergence of these new health problems related to opioid abuse has precipitated this MiniReview on the status of the most hazardous and common opioid adulterants. In fact, adulterated opium is a major public health problem and can threaten the health of users. In this study, we searched for information on opium, opiates, lead poisoning, toxicity, intoxication, Iran and heavy metals in the TUMS Digital Library, PubMed, Scopus, EMBASE and Google Scholar bibliographical databases. This MiniReview primarily included articles on lead poisoning, signs and symptoms, and management in opioid-dependent individuals. Exclusion criteria were articles dealing with animal studies, specific paediatric studies, adulterants other than heavy metals and substances other than opioids. Adulterated opium is one of the new sources of exposure to lead and has precipitated an increase in lead-poisoned cases owing to the widespread use of opium. The toxicology of lead and general guidelines on diagnosis and treatment of lead poisoning is briefly reviewed. The symptoms of lead toxicity mimic several diseases often leading to unnecessary diagnostic methods, misdiagnoses and even surgery. Finally, owing to the fact that lead toxicity shows non-specific signs and symptoms, screening for this disease, by taking blood samples and assessing blood lead levels in high-risk people, should be given an utmost priority. It is recommended that screening tests are adopted and applied for any drug-abusing patient with non-specific subacute signs and symptoms like abdominal pain, constipation and anaemia.

BACKGROUND: It has been demonstrated that chronic opium abusers have lower thresholds for pain. In this study we sought to determine whether chronic opium abuse has any effect on the duration of spinal block by local anesthetics. METHODS: In a case-controlled study, 50 opium abusers and 50 nonabusers undergoing lower abdomen operations were selected from among the patients admitted to a university hospital for elective surgery. All patients received 100 mg hyperbaric preservative-free 5% lidocaine in dextrose, intrathecally. RESULTS: The duration of anesthesia was much shorter in the opium abusers (60 +/- 7 min) than in the nonabusers (83 +/- 10 min) (P < 0.0001). CONCLUSION: The study documents a shortened duration of spinal block in opium abusers.

INTRODUCTION: The global epidemic of opiate use continues to spread and is an increasing burden especially in developing countries. Acute opiate overdose (AOO) is one of the most dramatic complications of drug abuse. The purpose of this study is to examine the epidemiology of acute opiate overdose in a poisoning center in Tehran. METHODS: In this cross-sectional survey, patients who attended the emergency room of Loghman-Hakim hospital - the only poisoning center in Tehran - and diagnosed with acute opiate overdose over a six month period were included. RESULTS: Overdose was more common among men (91.2%). The mean and standard deviation of age was 36.9+/-15. The most frequent opiate agent was opium (56.5%) followed by heroin. Opium was most commonly used by regular users, as a single agent and through ingestion. Benzodiazepines, antidepressants and alcohol were the most common agents consumed accompanied with opiates. The mortality rate was 8.8% which was not significantly different between cases of heroin and opium overdose. CONCLUSION: Opium was the major cause of overdose in our study. This result suggests that opium is not a harmless form of addiction although it is regarded as a thing of the past in many countries.
