In this article, we describe a middle-aged woman with a history of addiction to opioid medications who eventually became dependent on kratom. Her kratom-related withdrawal symptoms responded to a trial of buprenorphine-naloxone. Subsequently, she was maintained on this medication.

Scale formation on surfaces can normally be divided into two distinct processes: a “deposition process” which refers to the process of heterogeneous nucleation and growth at the asperities of the surface and an “adhesion process” which refers to the sticking of pre-existing crystals, which have nucleated in the bulk solution, and which build up as a layer on the surface. It has been presented in this paper that the surface scale formation rate is more dominantly controlled by the “deposition process” rather than the “adhesion process”. However, the level of agitation could have inverse effects on one process to another. Only a small amount of research has been done to understand the differences of the kinetics of each of these processes. The presented work represents an experimental study of scaling tests to assess the effect of hydrodynamic conditions, using Rotating Cylinder Electrode (RCE), in a complex scaling environment, particularly supersaturated with barium/strontium sulphate and calcium carbonate, on the stainless steel substrate coated with a wide range of different industrial coatings. In addition, the effect of the surface energy and surface roughness on both processes has been studied. The paper provides data that will assist in the understanding of the controlling parameters in scale formation in different conditions, and also describes what characteristics of the surface can make it a good anti-scale surface for inorganic scale; however, the results have showed that merely one parameter cannot assure a surface as a good antifouling surface.

OBJECTIVE:: Several novel synthetic amphetamines have been marketed worldwide as "bath salts." The use of bath salts is associated with severe medical consequences resulting in a US federal ban over the last 3 years on the more common substances found in this group. Bath salts intoxication has a relatively nonspecific presentation, and urine toxicology confirmation in emergency departments (EDs) is impractical because the turnaround time is several days. Emergency clinicians must therefore rely heavily on patients' self-reports to verify the diagnosis. We performed an online survey of emergency clinicians to determine their degree of exposure to bath salts-intoxicated patients, the clinically relevant features of such patients, and the typical emergency management. METHODS:: We invited 124 physicians and physician assistants in 7 Cleveland Clinic EDs to participate in an online survey. RESULTS:: From a total of 43 of the 124 respondents, 77% did not specifically ask patients about bath salts use. Sixty percent had encountered a bath salts-intoxicated individual. Most respondents reported that the majority of patients were male, were between 19 and 29 years old, and used other drugs in addition to bath salts. Agitation, aggression/violence, and hallucinations were reported to be the most common presentations, and intravenous/intramuscular tranquilization was reported as the most often used management. Most patients were discharged home from the ED. CONCLUSIONS:: Despite the lack of toxicology screening in EDs, about two thirds of the surveyed emergency clinicians encountered bath salts-intoxicated individuals. Our study demonstrates the need for increased screening of bath salts intoxication in EDs, especially in agitated patients. Language: en

Historically, there has been a restrictive approach toward outpatient parenteral antimicrobial therapy (OPAT) in patients with injection drug use (IDU) due to the fear that they might utilize the intravenous catheter to inject illicit substances.We tested the hypothesis that patients with current IDU on OPAT would have less favorable treatment outcomes compared to those without current IDU.In this retrospective cohort chart review study of Cleveland Clinic OPAT registry, we identified patients with current IDU by both electronic and manual review. For each patient with current IDU, we identified 3 matched controls among those on OPAT and without current IDU, by propensity score matching on age, sex, OPAT year, and OPAT diagnosis. We compared treatment failure, infection relapse, line infection, hospital readmission, number of emergency room visits, and 90-day mortality, for patients with current IDU and their matched controls.We identified 39 patients with current IDU and 117 matched controls. Most patients with current IDU (82%) were discharged to skilled nursing facilities, whereas the majority of the control group (74%) was treated at home (p0.01). There was no significant difference in the examined treatment outcomes between the 2 groups.Patients with current IDU on OPAT did not have less favorable treatment outcomes compared to those without current IDU. Although the reason for this finding could potentially be related to difference in disposition, more studies need to be done to assess safety of home disposition among these patients.

Mineral scale deposition on surfaces of oil production equipment has been recognised as a major flow assurance problem. Most of the mineral scale deposition work published has solely focused on laboratory experiments and very little data are available that demonstrate such results are relevant and can be scaled-up to field environments. The current study focuses on mineral scale formation on surfaces and compares laboratory results with field data. A field test has been running for half a year on commercially-coated pipe spools along with uncoated ones. The different pipe sections were positioned along a water line injection system in an oilfield. In the laboratory, a standard bulk jar test was used and the ability of a range of chemically and morphologically modified coatings to prevent/reduce mineral scale surface fouling were assessed under different flow conditions (ranging from laminar to turbulent flow). The current study shows that if properly selected, surface engineering offers great promise as an approach to prevent mineral scale deposition in the piping system of oilfields.

Driven by opioid use, HIV prevalence is high (15-27%) amongst injection drug users (IDU) in Iran. Harm reduction programmes are associated with a reduction in high risk injecting behaviours; however, Iran has a large number of non-injecting opioid users not immediately targeted by harm reduction programmes. The vast majority of heroin injectors tend to have a history of several years of smoking opium or heroin before transitioning to injection, and a small fraction may even start their drug career by injection of opioids, behaviours that can undermine the effectiveness of the harm reduction programmes. In this study, we have reviewed evidence on the HIV epidemic, extent and pattern of opioid use, and correlates of the transition to injection in Iran. We have concluded that harm reduction policies should also emphasize prevention of the transition to injection amongst high-risk non-injecting opioid users as an additional strategy against the spread of HIV infection in Iran.

This study was conducted to compare needle and syringe sharing practices among injecting drug users (IDUs) in two neighborhoods, one with and one without a needle and syringe program (NSP). In 2005, 419 street-based IDUs were interviewed at specific locations in two neighborhoods where IDUs are known to congregate. We compared self-reported needle and syringe access and use between IDUs from a neighborhood with an active NSP to IDUs from a neighborhood without such an intervention. A significantly smaller proportion of IDUs from the former neighborhood reported having used a shared needle/syringe over a 1-month period (21.0%) compared to IDUs from the latter neighborhood (39.9%; adjusted odds ratio, 0.24; 95% confidence interval, 0.13-0.45). These findings indicate that access to an NSP may reduce needle and syringe sharing practices. Therefore, these programs should be intensified in settings with concentrated HIV epidemics among IDUs in Iran.

This study aimed to investigate the prevalence and correlates of hepatitis C virus infection among injecting drug users in a community-based setting in Tehran, Iran. In October 2004, injecting drug users were recruited from a drop-in centre and neighboring parks and streets in a drug-populated neighborhood in Tehran. Participants were interviewed using a structured questionnaire, and a sample of oral mucosal transudate was collected for detection of HIV and HCV antibodies. Overall, 105 of 202 participants (52.0%) were found to be positive for HCV-antibody testing. After adjustment for the basic demographic characteristics, the prevalence of HCV infection was found to be associated with length of drug injection (more than 10 years) [odds ratio (OR), 3.25; 95% confidence interval (CI), 1.43-7.38], length of lifetime incarcerations (more than a year) (OR, 3.44; 95% CI, 1.68-7.06), and a history of being tattooed inside prison (OR, 1.96; 95% CI, 1.06-3.62). High prevalence of HCV infection and its association with incarceration-related exposures are important implications for harm reduction initiatives for drug using inmates in Iran. While prevention interventions for drug using inmates are being expanded in Iran, it is important that high prevalence of HCV infection be taken into consideration in order to control further transmission of this infection.

Major opium trafficking routes traverse rural Iran, but patterns of drug use and HIV infection in these areas are unknown. In 2004, Iran’s Ministry of Health integrated substance use treatment and HIV prevention into the rural primary health care system. Active opium or heroin users (N = 478) were enrolled in a rural clinic. Participants received counseling for abstinence from substances, or daily needle exchange and condoms. On enrollment, 108 (23%) reported injecting; of these, 79 (73%) reported sharing needles. Of 65 participants tested for HIV, 46 (72%) tested positive. Participants who received daily needle exchange/condoms stayed in the program longer than those who did not (AOR 2.08, 95% CI 1.1–3.88). This project demonstrates that HIV risks exist in rural Iran and suggests the innovative use of Iran’s rural health care system to extend prevention and treatment services to these populations.

The objectives were to determine the prevalence and correlates of HIV-1 infection among community-based injecting drug users (IDUs) in Tehran Iran. In October 2004 213 IDUs were recruited from a drop-in center and its neighboring parks and streets in Tehran. Participants were interviewed using a structured questionnaire regarding their sociodemographics and HIV risk characteristics and specimens of oral mucosal transudate were collected and tested for HIV-1 antibodies. Data were analyzed using x/2 and multiple logistic regression to estimate odds ratios (OR) and 95% confidence intervals (CI). The prevalence of HIV-1 infection was 23.2% (48 of 207) among male injecting drug users. In the multivariable analysis a history of shared drug injection inside prison (OR 2.45; 95% CI 1.01-5.97) and that of multiple incarcerations (OR 3.13; 95% CI 1.08-9.09) were associated with significantly higher prevalence of HIV-1 infection. The prevalence of HIV-1 infection has reached an alarming level among IDUs in Tehran with incarceration-related exposures revealed to be the main correlates of HIV-1 infection. Urgent and comprehensive harm reduction programs for drug users in prison and those in the community in Tehran are of prime importance to prevent further transmission of HIV infection. (authors)

HIV infection rates have reached epidemic proportions amongst injecting drug users (IDUs) in Iran. Although a number of community-based interventions have being implemented in the country, there is little information on the risk behaviors of IDU participants in these programs. This cross-sectional report aimed to compare the risk behaviors of injecting drug users with differential exposure rates to an HIV outreach program in Tehran, Iran. Results indicated that shared use of needle/syringe in the past month was significantly lower among IDUs who received estimated ≥ 7 syringes per week than those who did not [adjusted odds ratio (OR) = 14.36, 95% confidence interval (CI) 2.30–89.56]. While the effectiveness of this outreach program needs further evaluation through a longitudinal investigation, our preliminary findings suggest that the outreach program in Tehran may have been beneficial in reducing direct sharing among those who received more than several needles/syringes from the program.

In the final days of the year 2003, an earthquake in the city of Bam, Iran, led to the death of some 35,000 of its inhabitants. The rate of opium abuse, which had been high among the male population in this city, caused problems after the earthquake. The aim of the following study was to examine the status of substance abusers during the first 2 weeks after the earthquake. The study was carried out in the city of Bam, one of its nearby villages and eight hospitals admitting earthquake victims. One hundred and sixty-three individuals were interviewed, including substance abusers, their family members, people living in Bam, service providers, and the authorities. During the first 2 weeks after the earthquake, about half of drug-dependent interviewees suffered from withdrawal symptoms. About half reported their problems to health care providers and asked for morphine or other analgesics. Around one third had used opium on the first day and two thirds in the course of the second day to the end of the second week after the earthquake. Although smoking had been the most common means of abuse before the earthquake, oral intake has become the most prevalent route after the disaster. Almost all obtained their opium from inhabitants of other cities as gifts. Members of rescue and health delivery systems had a lot of encounters with opium abusers, especially in the first 3 days after the earthquake, and had prescribed morphine and other analgesics. In societies with a considerable prevalence of substance abuse, this issue becomes a matter of utmost health care and social importance at times of disasters, and the necessary arrangements to deal with it should be present beforehand.

This study was conducted to identify the prevalence of and potential risk factors for HIV-1 infection among drug users visiting drug treatment centers in Tehran Iran. Design: Cross-sectional quantitative study. Between October 2003 and May 2004 drug users who visited three public drug treatment centers in Tehran were interviewed and information about their sociodemographics drug use characteristics incarceration history sexual history and HIV/ AIDS knowledge and risk perception were collected. Specimens of oral mucosal transudate were then collected from participants to be tested for HIV-1 antibodies. Logistic regression analysis was conducted on the association between the demographic and behavioral factors with HIV-1 infection. Overall 611 (588 male and 23 female) drug users participated in the study. Among male injectors with HIV-1 prevalence of 15.2% a history of shared injection inside prison [adjusted odds ratio (OR) 12.37; 95% confidence interval (CI) 2.94– 51.97] was the main factor associated with HIV-1 infection. Among those who reported no history of injecting drug use HIV-1 prevalence was 5.4% and lack of condom use during sex was significantly associated with the infection (adjusted OR 3.42; 95% CI 1.25–9.36). HIV-1 infection is already prevalent among drug users in Tehran Iran and shared injection inside prison has been revealed to be a particular risk factor for HIV-1 infection among injecting drug users. Harm reduction programs which have been started in Iran should be urgently expanded particularly in correctional settings and strengthened by condom use promotion to prevent sexual acquisition or transmission of HIV-1 among drug users.
