BACKGROUND: Avatar-assisted therapy (AAT) is a novel and emerging technology that uses the Internet to enable clinicians and clients in substance abuse treatment to participate in group counseling sessions from separate and remote locations in real time through the use of avatars and virtual environments. OBJECTIVES: The current study is a pilot proof-of-concept feasibility study involving individuals in outpatient substance abuse treatment. This report addresses two questions: (1) are individuals who present for substance abuse treatment interested in receiving AAT and (2) what factors are associated with better treatment success...

Drugged driving has become more prevalent than drunk driving and is quickly gaining national attention due to increased prescription drug abuse and recent cannabis legalization. Unlike alcohol, police officers do not generally have access to approved devices to screen for drugs at the roadside. Onsite drug screening devices do exist and are used in other countries, but have not garnered widespread approval for use in the United States in driving under the influence of drugs (DUID) cases. One reason for this is that the devices are designed to test oral fluid, which is not a commonly accepted specimen for DUID...

A highly sensitive method for the determinations of acebutolol, clenbuterol, nadolol, oxprenolol, propranolol, terbutaline and timolol β-blockers and β2-agonists in plasma and urine was developed. The method was optimized using electrospray ionization liquid chromatography-tandem mass spectrometry (LC-ESI-MS-MS) and clean screen solid phase extraction cartridges. Matrix effect was reduced by removing co-extractives from the SPE cartridges using methanol prior to drugs' elution. Using blood and serum matrices for calibration and applying the internal standard method has also contributed to the reduction of matrix effect...

Buprenorphine/naloxone, methadone and lofexidine are medications with utility in the treatment of opiate withdrawal. We report the first randomised controlled trial to compare the effects of these two medications on withdrawal symptoms and outcome during opiate induction/stabilisation and detoxification. A double-blind randomised controlled trial was conducted in an outpatient satellite clinic of a specialist drug service. Eighty opiate dependent individuals meeting DSM-IV criteria for opiate dependence, using ⩽ ½ g heroin smoked/chased or ¼ g heroin injected or ⩽ 30mg methadone, with ⩽ 3 years of opioid dependency, underwent a short-term opiate treatment programme involving induction/stabilisation on methadone 30mg or buprenorphine/naloxone 4mg/1mg, followed by detoxification (where the methadone group was assisted by lofexidine)...

CONTEXT: Multiple studies have concluded that urine drug screens rarely change clinical management. The rapid comprehensive urine drug screen (RCUDS) at our institution detects over 300 substances using a combination of EIA and GC/MS and typically takes 2-5 h for completion. OBJECTIVE: We sought to determine whether this RCUDS altered management in the pediatric population. METHODS: All patients >1 month and <18 years of age in which a RCUDS was completed from 1 January 2012 to 31 December 2012 were eligible for the study...

BACKGROUND: We sought to test the effectiveness of methadone and buprenorphine in the treatment of methamphetamine withdrawal craving over a 17-day treatment period. METHODS: Patients were randomized into one of two groups. The study sample comprised 40 male subjects dependent on methamphetamine who met criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, for methamphetamine dependence and withdrawal and were seeking treatment. Furthermore, they should have a history of daily methamphetamine use for at least 6 months and should have discontinued their use just before starting the protocol...

Carfentanil is a fentanyl analog frequently used in large animal veterinary medicine. Recently, carfentanil has been discovered in postmortem and antemortem cases throughout the United States in the heroin supply either alone or mixed with heroin and/or other fentanyl analogs. The potency of carfentanil is ~10,000 times greater than morphine and 100 times greater than fentanyl. In two recent cases, carfentanil was identified and ruled to be the cause of death, either alone or in combination with other drugs...

Drug use during methadone induction/stabilization negatively influences later methadone-maintenance-treatment [MMT] outcomes (retention, abstinence). Our study examined the association of baseline risk factors to drug use during the first month of methadone treatment as well as longer-term treatment retention. We conducted these analyses among a race/ethnic minority group at high risk for worse MMT outcomes. African-American MMT patients (N=212) were interviewed at intake to assess clinical (drug use history), psychosocial (close family member substance abuse, psychosocial problems), and demographic factors...

Eating poppy seeds can cause a positive urine drug screen, but it is unknown whether ingesting large quantities can result in opiate intoxication or toxicity. A 54-year-old woman with intractable vomiting was found unresponsive at home and later pronounced dead. At autopsy, a cast-like large bowel obstruction composed of poppy seeds was identified. Postmortem blood morphine level was < 10 ng/mL. Cause of death was determined to be complications of a bowel obstruction secondary to poppy seed ingestion. Deaths related to eating poppy seeds have not been described in the literature...

Thomas G Rosano, Patrice Y Ohouo, Michelle Wood
Drug and metabolite (analytes) identification together with quantification is an important analytical tool in forensic and clinical toxicology. We report the development and validation of a definitive detection and quantification method (UPLC-MS-MS) for initial screening of 64 analytes in urine. The principle of the method is a quantitative extension of a recently reported threshold accurate calibration (TAC) technique which employs a rapid dual-specimen analysis i.e., with and without addition of a reference-analyte standard for normalization of matrix effects...

Tianeptine (7-[([3-chloro-6,11]-dihydro-6-methyldibenzo[c,f][1,2]thiazepin-11-yl) amino] heptanoic acid S, S dioxide) is a tricyclic compound prescribed as an antidepressant in European countries, but is not currently approved for use in the United States. There are few published case reports of tianeptine intoxication. Presented is the first case of acute toxicity associated with the intravenous use of tianeptine. A 36-year-old male intentionally injected tianeptine powder intravenously to "help him see into the future"...

We introduce a label-free biosensing cellulose strip sensor with surface-enhanced Raman spectroscopy (SERS)-encoded bimetallic core@shell nanoparticles. Bimetallic nanoparticles consisting of a synthesis of core Ag nanoparticles (AgNP) and a synthesis of shell gold nanoparticles (AuNPs) were fabricated on a cellulose substrate by two-stage successive ionic layer absorption and reaction (SILAR) techniques. The bimetallic nanoparticle-enhanced localized surface plasmon resonance (LSPR) effects were theoretically verified by computational calculations with finite element models of optimized bimetallic nanoparticles interacting with an incident laser source...

Ketamine immunoassay urine drug screen (UDS) is commonly used in Taiwan. However, there was limited report about possible drug which may cause false positive results in ketamine screen test. We report two cases who used quetiapine showed positive in ketamine urine immunoassay screen initially, and found to be false positive in confirmation test. Clinicians should be aware of the false positive result of ketamine UDS caused by currently used medication.

OBJECTIVE: Previous trials of catheter-based renal-artery denervation (RDN) as treatment modality in resistant hypertension (rHT) generated unconvincing results. In the Investigator-Steered Project on Intravascular Denervation for Management of Treatment-Resistant Hypertension (INSPiRED; NCT01505010), we optimized selection and management of rHT patients. METHODS: With ethical clearance to randomize 18 patients, three Belgian hypertension centers screened 29 rHT patients on treatment with ≥3 drugs, of whom 17 after optimization of treatment (age <70 years; systolic/diastolic office blood pressure (BP) ≥ 140/90 mm Hg; 24-h BP ≥130/80 mm Hg; glomerular filtration rate [eGFR] ≥ 45 mL/min/1...

Prescription opioid use for relief of noncancer pain has risen dramatically in the last 15 years, contributing to a quadrupling of opioid overdoses and prescription opioid-related deaths. This crisis is resulting in heightened attention by health care professionals and organizations, law enforcement, and the government. In this article, I highlight key topics in the management of patients using opioids (or potentially needing opioids) in outpatient clinical practice; federal and state law enforcement actions regarding physicians' illegal prescribing of opioids; multimodal approaches to pain control; nonmedication management of pain; response strategies when suspecting a patient of diverting or misusing opioids; and warning signs for abuse or diversion...
