Smita Das, Nina Shah, Murtuza Ghadiali
BACKGROUND: Opioid overdose is a growing concern in the United States and internationally. Prehospital or pre-medical-personnel (lay person) administration of naloxone, an opioid antagonist, to reverse overdose, is an expanding mode of harm reduction. Recently, community clinics, methadone clinics, needle exchanges, some pharmacies and other health care facilities have made naloxone available to the community. CASE: This case describes heroin overdose reversal of a 28-year-old male who had been using about a gram of heroin intravenously for 3 years, but recently reduced frequency of use in an attempt to stop...

Hepatitis C Virus (HCV) is easily spread among those who share drug injection equipment. Due to the ease of contraction and growing prevalence of HCV in Eastern Europe, the aims of this study focused on describing risky injection practices as well as the prevalence of HCV, HIV, and Hepatitis B Virus (HBV) among people who inject drugs (PWID) that were admitted to public and private drug treatment centers in Turkey from 2012 to 2013. Other aims included identifying correlates of needle sharing and HCV infection...

Many illicit drugs involve the use of paraphernalia, and the presence of paraphernalia found at the scene of death may suggest that the death is drug-related. Few sources of objective data are available regarding the prevalence of drug paraphernalia found at the scene of drug-related deaths or the likelihood of a death with drug paraphernalia found at the scene to be drug-related. This study reviews the deaths which were investigated by the Bexar County Medical Examiner's Office in an attempt to provide objective data...

Opioid addiction, including addiction to heroin, has dramatically increased in the last decade. The cost and pervasiveness of heroin addiction, including resistance to recovery from addiction, provide a compelling basis for developing novel therapeutic strategies. Deep brain stimulation may represent a viable alternative strategy for the treatment of intractable heroin addiction particularly in individuals who are resistant to traditional therapies. Here, we provide preclinical evidence of the therapeutic potential of high-frequency stimulation of the subthalamic nucleus (STN HFS) for heroin addiction...

BACKGROUND: We examined discharges for infective endocarditis (IE) at an academic teaching hospital for over 10 years to evaluate if an increase in hospitalizations for IE and increase in hepatitis C virus (HCV) in patients with IE could predict a new epidemic of injection drug use (IDU). MATERIALS AND METHODS: Retrospective medical record review of discharged patients with the diagnosis of IE as defined by the modified Duke criteria. Student's t test, chi-squared test and Fisher's exact test were used to calculate P values...

BACKGROUND: In heroin injectors, there have been a number of outbreaks caused by spore-forming bacteria, causing serious infections such as anthrax or botulism. These are, most likely, caused by injecting contaminated heroin, and our aim was to develop a filter that efficiently removes these bacteria and is also likely to be acceptable for use by people who inject drugs (i.e. quick, simple and not spoil the hit). METHODS: A prototype filter was designed and different filter membranes were tested to assess the volume of liquid retained, filtration time and efficiency of the filter at removing bacterial spores...

BACKGROUND: Herpes simplex virus type 2 (HSV-2) infection increases both susceptibility to and transmissibility of human immunodeficiency virus (HIV), and HSV-2 and HIV are often strongly associated in HIV epidemics. We assessed trends in HSV-2 prevalence among non-injecting drug users (NIDUs) when HIV prevalence declined from 16% to 8% among NIDUs in New York City. METHODS: Subjects were current non-injecting users of heroin and/or cocaine and who had never injected illicit drugs...

The United States is amid an epidemic of prescription opioid drug abuse, bringing with it not only high rates of overdose, but growing rates of heroin abuse and addiction. Liberal opioid drug prescribing on the part of well-meaning clinicians has in part fueled this epidemic, being correlated to opioid death and addiction treatment admission rates. Misuse and abuse of prescription opioid drugs is greatest among young adults (ages 18 to 25); however, the fastest growing age group for opioid drug misuse/abuse is older (ages 50 to 64)...

BACKGROUND: Heroin use by non-injecting routes of administration (snorting, swallowing, "chasing the dragon") is considered to be safer but is not risk-free for fatal overdose or serious side effects. We report the case of an adolescent who was transferred unconscious to the emergency department after heroin inhalation. Description of the case: A 17-year-old male was transferred to the emergency department unconscious (Glasgow coma scale: 6/15) after heroin inhalation. He was treated with non-rebreather mask and intravenous infusion of naloxone with gradual improvement of consciousness and arterial blood gasses...

Most of the research on public perceptions of people with addictive disorders has focused on alcohol and illicit drugs, rather than addiction to behavioral activities. To expand the range of addictive behaviors and types of perceptions studied, we designed the present study to assess the lay public's definitions of and willingness to affiliate with people described as addicted to 1 of 2 specific behaviors (i.e., pornography or gambling) or 1 of 3 specific substances (i.e., alcohol, marijuana, or heroin). A nationwide convenience sample (N = 612) of American adults completed online questionnaires during the summer of 2015...

From the Aristotelian ancient Greece, pain has been associated with appetites or emotions and is opposite to pleasure. Reward and addiction is also linked to pleasure and compulsive drug seeking reinstates pleasure. Alleviation of chronic pain can induce a euphoric phase similar to what is found in addiction. Both chronic pain and addiction are recognized as a disease of the central nervous system. They share many characteristics and brain regions/mechanisms. Evidence points to the usefulness of cannabinoids as a new class of agents to add to the pharmaceutical toolbox in the management of chronic pain...

Although opioids are highly efficacious analgesics, their abuse potential and other untoward side effects diminish their therapeutic utility. The addition of non-opioid analgesics offers a promising strategy to reduce required antinociceptive opioid doses that concomitantly reduce opioid-related side effects. Inhibitors of the primary endocannabinoid catabolic enzymes fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL) show opioid-sparing effects in preclinical models of pain. As simultaneous inhibition of these enzymes elicits enhanced antinociceptive effects compared with single enzyme inhibition, the present study tested whether the dual FAAH-MAGL inhibitor SA-57 [4-[2-(4-chlorophenyl)ethyl]-1-piperidinecarboxylic acid 2-(methylamino)-2-oxoethyl ester] produces morphine-sparing antinociceptive effects, without major side effects associated with either drug class...

BACKGROUND: The popularization of anonymous markets such as Silk Road is challenging current drug policy and may provide a new context for old issues, such as adulteration of heroin with fentanyl derivatives. The aims of this paper are to report the presence of ocfentanil, a novel, potent, non-controlled fentanyl analog, in samples sold as heroin in the hidden web, and to summarize the effects reported by users. METHODS: In 2015, four samples allegedly bought as heroin in cryptomarkets of the hidden web were sent to Energy Control for analysis...

Drug addiction is a major health problem worldwide. Recent neuroimaging studies have shed light into the underlying mechanisms of drug addiction as well as its consequences to the human brain. The most vulnerable, to heroin addiction, brain regions have been reported to be specific prefrontal, parietal, occipital, and temporal regions, as well as, some subcortical regions. The brain regions involved are usually linked with reward, motivation/drive, memory/learning, inhibition as well as emotional control and seem to form circuits that interact with each other...

OBJECTIVES: Outbreaks of HIV infection have been linked to injectable drug abuse, but specific triggers often remain obscure. We report on an outbreak of primary HIV infection among people who inject drugs (PWID) in Tel Aviv, associated with a local shift in drug-use practices. METHODS: A cluster of primary HIV infection cases in PWID was detected in May 2012. Retrospective and prospective multi-hospital case finding was initiated. PWID were interviewed and risk factors for primary HIV infection were identified...

INTRODUCTION: A fixed hemodynamic response function (HRF) is commonly used for functional magnetic resonance imaging (fMRI) analysis. However, HRF may vary from region to region and subject to subject. We investigated the effect of locally estimated HRF (in functionally homogenous parcels) on activation detection sensitivity in a heroin cue reactivity study. METHODS: We proposed a novel exploratory method for brain parcellation based on a probabilistic model to segregate the brain into spatially connected and functionally homogeneous components...

BACKGROUND: Results of the randomised, double-blind, placebo-controlled Bangkok Tenofovir Study (BTS) showed that taking tenofovir daily as pre-exposure prophylaxis (PrEP) can reduce the risk of HIV infection by 49% in people who inject drugs. In an extension to the trial, participants were offered 1 year of open-label tenofovir. We aimed to examine the demographic characteristics, drug use, and risk behaviours associated with participants' uptake of and adherence to PrEP. METHODS: In this observational, open-label extension of the BTS (NCT00119106), non-pregnant, non-breastfeeding, HIV-negative BTS participants, all of whom were current or previous injecting drug users at the time of enrolment in the BTS, were offered daily oral tenofovir (300 mg) for 1 year at 17 Bangkok Metropolitan Administration drug-treatment clinics...

BACKGROUND: Opiate abuse and overdose reached epidemic levels in the United States. However, despite significant advances in animal and in vitro models, little knowledge has been directly accrued regarding the neurobiology of the opiate-addicted human brain. METHODS: We used postmortem human brain specimens from a homogeneous European Caucasian population of heroin users for transcriptional and epigenetic profiling, as well as direct assessment of chromatin accessibility in the striatum, a brain region central to reward and emotion...
