Abstract
Opioids are powerful analgesic drugs that are used clinically to treat pain. However, chronic opioid use causes compensatory neuroadaptations that result in greater pain sensitivity during withdrawal, known as opioid withdrawal-induced hyperalgesia (OWIH). Cold nociception tests are commonly used in humans, but preclinical studies often use mechanical and heat stimuli to measure OWIH. Thus, further characterization of cold nociception stimuli is needed in preclinical models. We assessed three cold nociception tests-thermal gradient ring (5-30 °C, 5-50 °C, 15-40 °C, and 25-50 °C), dynamic cold plate (4 °C to -1 °C at -1 °C/min, -1 °C to 4 °C at +1 °C/min), and stable cold plate (10 °C, 6 °C, and 2 °C)-to measure hyperalgesia in a mouse protocol of heroin dependence. On the thermal gradient ring, mice in the heroin withdrawal group preferred warmer temperatures, and the results depended on the ring's temperature range. On the dynamic cold plate, heroin withdrawal increased the number of nociceptive responses, with a temperature ramp from 4 °C to -1 °C yielding the largest response. On the stable cold plate, heroin withdrawal increased the number of nociceptive responses, and a plate temperature of 2 °C yielded the most significant increase in responses. Among the three tests, the stable cold plate elicited the most robust change in behavior between heroin-dependent and nondependent mice and had the highest throughput. To pharmacologically characterize the stable cold plate test, we used μ-opioid and non-opioid receptor-targeting drugs that have been previously shown to reverse OWIH in mechanical and heat nociception assays. The full μ-opioid receptor agonist methadone and μ-opioid receptor partial agonist buprenorphine decreased OWIH, whereas the preferential μ-opioid receptor antagonist naltrexone increased OWIH. Two N-methyl-d-aspartate receptor antagonists (ketamine, MK-801), a corticotropin-releasing factor 1 receptor antagonist (R121919), a β2-adrenergic receptor antagonist (butoxamine), an α2-adrenergic receptor agonist (lofexidine), and a 5-hydroxytryptamine-3 receptor antagonist (ondansetron) had no effect on OWIH. These data demonstrate that the stable cold plate at 2 °C yields a robust, reliable, and concise measure of OWIH that is sensitive to opioid agonists.

Abstract
BACKGROUND Pharmacotherapeutic options for the treatment of opioid withdrawal are limited by abuse potential, adverse effects, and lack of availability of existing drugs. The results from previous clinical trials on tramadol are contradictory and non-conclusive; hence the present meta-analysis was conducted to evaluate the efficacy and safety of tramadol in the treatment of opioid withdrawal. METHODS Reviewers extracted data from eight relevant clinical trials after a literature search on MEDLINE/PubMed, Cochrane databases, and clinical trial registries. Quality assessment was done using the risk-of-bias assessment tool, and the random-effects model was used to estimate effect size in frequentist and Bayesian approaches. Subgroup analysis, meta-regression, and sensitivity analysis were done as applicable. PRISMA guidelines were followed in reporting findings. RESULTS Tramadol significantly reduced opioid withdrawal scale score (SMD: -0.44; 95%CI: -0.76 to -0.13; PI: -1.54 to 0.71; p = 0.006) when all comparators were considered together in the frequentist approach but the reduction was non-significant in Bayesian approach. However, the subgroup analysis revealed no significant difference between tramadol and comparators like placebo (SMD: -1.12; 95%CI: -2.69 to 0.45) buprenorphine (SMD: -0.21; 95%CI: -0.43 to 0.01), clonidine (SMD: -0.26; 95%CI: -0.55 to 0.02) and methadone (SMD: -0.84; 95%CI: -1.78 to 0.10). Meta-regression showed non-significant associations between the SMD in opioid withdrawal score with the duration and dose of tramadol therapy. There were no significant differences in treatment retention at the end of studies between tramadol and comparators. Safety data in the individual studies were inadequate to analyze. CONCLUSION Authors conclude that the efficacy of tramadol in reducing opioid withdrawal symptoms is not significantly different from comparators with low certainty of evidence against placebo, moderate against methadone, whereas with high certainty of evidence against buprenorphine and clonidine.

Abstract
RATIONALE Super-refractory status epilepticus is a serious illness with high morbidity and mortality, which is defined as an SE that continues or recurs 24 hours or more after the onset of anesthesia. Anesthetic agents can be either pro-convulsant or anticonvulsant or both. PATIENT CONCERNS Epilepsy occurred at the age of 3 years. At the age of 4 years, generalized tonic-clonic seizure occurred for the first time. The patient was hospitalized at the age of 27 and 28 years for treating status epilepticus. At the age of 33 years, antiepileptic drugs were stopped due to poor appetite. In an early morning, the patient was found delirious with reduced speech. DIAGNOSIS Occasionally, the patient blinked his eyelids, or deflected his eyeballs to 1 side. When propofol was lowered to 10 mL/H, the epileptic wave reduced obviously. Afterwards, the patient opened his eyes autonomously and his consciousness gradually recovered. The patient could answer questions, and the limbs had voluntary movements. The patient breathing also gradually recovered, and his urine gradually returned to pale yellow from green. After anesthetic was stopped for 10 days, the patient lost his consciousness again. The patient eyes turned upward frequently, which was relieved in 1 to 2 seconds with an attack once every 2 to 5 minutes. INTERVENTIONS Clonazepam was gradually reduced to 2 mg qn, and the patient gradually woke up during this process. The patient was also treated with levetiracetam 1.5 g bid, oxcarbazepine 0.6 g bid, topiramate 50 mg bid and valproate 0.4 g tid. OUTCOMES After 1 month follow-up, status epilepticus did not appear again. LESSONS Propofol aggravated the tonic seizures. As tonic seizures occur during natural sleep and after sleep induced by various narcotic drugs, the decrease of consciousness level induced by excessive sedation of narcotic drugs has been suggested as the reason for poor seizure control.

Abstract
Opioid misuse has dramatically increased over the last few decades resulting in many people suffering from opioid use disorder (OUD). The prevalence of opioid overdose has been driven by the development of new synthetic opioids, increased availability of prescription opioids, and more recently, the COVID-19 pandemic. Coinciding with increases in exposure to opioids, the United States has also observed increases in multiple Narcan (naloxone) administrations as a life-saving measures for respiratory depression, and, thus, consequently, naloxone-precipitated withdrawal. Sleep dysregulation is a main symptom of OUD and opioid withdrawal syndrome, and therefore, should be a key facet of animal models of OUD. Here we examine the effect of precipitated and spontaneous morphine withdrawal on sleep behaviors in C57BL/6 J mice. We find that morphine administration and withdrawal dysregulate sleep, but not equally across morphine exposure paradigms. Furthermore, many environmental triggers promote relapse to drug-seeking/taking behavior, and the stress of disrupted sleep may fall into that category. We find that sleep deprivation dysregulates sleep in mice that had previous opioid withdrawal experience. Our data suggest that the 3-day precipitated withdrawal paradigm has the most profound effects on opioid-induced sleep dysregulation and further validates the construct of this model for opioid dependence and OUD.

Abstract
INTRODUCTION The association of preoperative narcotic use with postoperative outcomes after primary elective total knee arthroplasty (TKA) has remained poorly characterized. The NarxCare platform analyzes patients' state Prescription Drug Monitoring Program records to assign numerical scores that approximate a patient's overall opioid usage. The present study investigated the utility of admission NarxCare narcotic scores in predicting the odds of adverse events (AEs) after primary elective TKA. METHODS Elective primary TKA patients performed at a single institution between October 2017 and May 2020 were evaluated. NarxCare narcotic scores at the time of admission, patient characteristics, 30-day AEs, readmissions, revision surgeries, and mortality were abstracted. Elective TKA patients were binned based on admission NarxCare narcotic scores. The odds of experiencing adverse outcomes were compared. RESULTS In total, 1136 patients met the criteria for inclusion in the study (Narx Score 0: n = 293 [25.8%], 1 to 99: n = 253 [22.3%], 100 to 299: n = 368 [32.4%], 300 to 499: n = 161 [14.2%], and 500+: n = 61 [5.37%]). By logistic regression, patients with higher admission narcotic scores tended to have a dose-dependent increase in the odds of prolonged length of hospital stay, readmission within 30 days, and aggregated AEs. DISCUSSION Admission narcotic scores may be used to predict readmission and to stratify TKA patients by risk of AEs.

Abstract
Background Opioid use disorder (OUD) is a chronic relapsing psychiatric disorder. An unconditioned stimulus (US)-triggers a memory reconsolidation updating procedure (MRUP) that has been developed and demonstrated its effectiveness in decreasing relapse to cocaine and heroin in preclinical models. However, utilizations of abused drugs as the US to initiate MRUP can be problematic. We therefore designed a translational rat study and human study to evaluate the efficacy of a novel methadone-initiated MRUP. Methods In the rodent study, male rats underwent heroin self-administration training for 10 consecutive days, and were randomly assigned to receive saline or methadone at 10 min, 1 h or 6 h before extinction training after 28-day withdrawal. The primary outcome was operant heroin seeking after reinstatement. In the human experimental study, male OUD patients were randomly assigned to get MRUP at 10 min or 6 h after methadone or methadone alone. The primary outcomes included experimental cue-induced heroin craving change, sustained abstinence and retention in the study at post intervention and the 5 monthly follow-up assessments. The secondary outcomes were changes in physiological responses including experimental cue-induced blood pressure and heart rate. Findings Methadone exposure but not saline exposure at 10 min or 1 h before extinction decreased heroin-induced reinstatement of heroin seeking after 28-day of withdrawal in rats (F (8,80) = 8.26, p < 0.001). In the human study, when the MRUP was performed 10 min, but not 6 h after methadone dosing, the MRUP promoted sustained abstinence from heroin throughout 5 monthly follow-up assessments compared to giving methadone alone without MRUP (Hazard Ratio [95%CI] of 0.43 [0.22, 0.83], p = 0.01). The MRUP at 10 min, but not at 6 h after dosing also decreased experimental cue-induced heroin craving and blood pressure increases during the 6-month study duration (group × months × cue types, F (12, 63·3) = 2.41, p = 0.01). Interpretation The approach of MRUP within about 1 to 6 h after a methadone dose potently improved several key outcomes of OUD patients during methadone maintenance treatment, and could be a potentially novel treatment to prevent opioid relapse.

Abstract
Background The coronavirus disease 2019 (COVID-19) has highlighted the scope of heroin dependence and need for evidence-based treatment amongst marginalised people in South Africa. Acute opioid withdrawal management without maintenance therapy carries risks of increased morbidity and mortality. Due to the high costs of methadone, Tshwane’s Community Oriented Substance Use Programme (COSUP) used tramadol for opioid withdrawal management during the initial COVID-19 response. Aim To describe demographics, route of heroin administration and medication-related experiences amongst people accessing tramadol for treatment of opioid withdrawal. Setting Three community-based COSUP sites in Mamelodi (Tshwane, South Africa). Methods A retrospective cross-sectional study was conducted. Data were collected using an interviewer-administered paper-based tool between April and August 2020. Descriptive statistics were used to analyse data. Results Of the 220 service users initiated onto tramadol, almost half (n = 104, 47%) were not contactable. Fifty-eight (26%) people participated, amongst whom most were male (n = 55, 95%). Participants’ median age was 32 years. Most participants injected heroin (n = 36, 62.1%). Most participants experienced at least one side effect (n = 47, 81%) with 37 (64%) experiencing two or more side effects from tramadol. Insomnia occurred most frequently (n = 26, 45%). One person without a history of seizures experienced a seizure. Opioid withdrawal symptoms were experienced by 54 participants (93%) whilst taking tramadol. Over half (n = 38, 66%) reported using less heroin whilst on tramadol. Conclusion Tramadol reduced heroin use but was associated with withdrawal symptoms and unfavourable side effects. Findings point to the limitations of tramadol as opioid withdrawal management to retain people in care and the importance of access to first-line opioid agonists. Contribution This research contributes to the limited data around short-acting tramadol for opioid withdrawal management in the African context, with specific focus on the need for increased access to opioid agonists for those who need them, in primary care settings.

Abstract
Drug-facilitated sexual assault (DFSA) and drug-facilitated crime (DFC) constitute a mode of violence that is generally unknown to the population and may go unnoticed by health professionals. The aim of this systematic review was to analyze the victims of DFC, compiling their sociodemographic characteristics, the toxic substances used and their biological matrices and modes of action, in order to identify the substances that are commonly put to criminal use. The aim would be to establish political and health strategies that inform and warn people about possible criminal social behaviors consequent danger to health. This systematic review was conducted following the PRISMA guidelines. Alcohol, benzodiazepines and cocaine were among the most commonly detected substances. In most of the hospitals, immunoassays, liquid chromatography (LC-MS), or gas chromatography-mass spectrometry (GC-MS) analyses were used to identify the substances, while the most frequently used biological matrices were blood and urine. From a judicial point of view, the instrumental protocols and techniques followed for the detection of toxics in different biological matrices must guarantee the reliability and validity of the results for use in a court of law. The recommendations of international organizations should be followed and must be called upon to strengthen their respective national laws against this chemical submission (CS) phenomenon.

Abstract
INTRODUCTION Foreign body emboli can lead to acute arterial insufficiency. We present a case report of upper extremity arterial insufficiency in an intravenous (IV) drug user secondary to intra-arterial injection of crushed tablet particles successfully treated with hyperbaric oxygen (HBO2) therapy. CASE A 37-year-old right-hand-dominant male developed pain and swelling of the left hand after attempting to inject crushed hydromorphone tablets into his venous circulation. Angiography revealed incomplete distal filling of the proper digital arteries, princeps pollicis, and radialis indicis branches of the left hand. The patient was treated with HBO2 for acute arterial insufficiency, secondary to these findings. Fluorescence angiography was performed prior to, during and after completion of HBO2, which showed improved perfusion of the hand upon completion of serial imaging. The patient underwent subsequent partial amputation of the left second digit and removal of the thenar and third finger pads. DISCUSSION Much of the literature on treatment of arterial insufficiency with HBO2 are in relation to chronic problem wounds. However, there is limited data on adjunctive treatment with HBO2 for foreign body embolism. Fluorescence angiography and clinical exam were used to track tissue perfusion and progression throughout course of therapy with HBO2. CONCLUSION Acute arterial insufficiency induced by foreign body embolism was successfully treated with HBO2 and provided increased tissue salvage of the patient's hand. The use of fluorescence angiography as a secondary measure of perfusion can provide additional insight regarding qualitative tissue oxygenation and may be a viable tool to track patient progress during HBO2 treatment.

Abstract
This article examines injectable Opioid Agonist Treatment (iOAT), in which patients suffering from long-term, treatment refractory opioid use disorder (OUD) are prescribed injectable diacetylmorphine, the active ingredient of heroin. While iOAT is part of the continuum of care for OUD in some European countries and in some parts of Canada, it is not an available treatment in the United States. We suggest that one reason for this situation is the belief that a genuine treatment for substance use disorder cannot prescribe the same substance as that used. We examine possible rationales for this belief by considering four combinations of views on the constitutive causal basis of substance use disorders and the definition of effective treatment. We show that all but one combination counts iOAT as a genuine treatment and that there are good reasons to reject the one that does not. Specifically, we claim that medical interventions, such as iOAT, that significantly reduce the severity of a disorder deserve to be categorized as effective treatments and regarded as such in practice.

Abstract
BACKGROUND The prevalence of substance use, both prescribed and non-prescribed, is increasing in many areas of the world. Substance use by women of childbearing age contributes to increasing rates of neonatal abstinence syndrome (NAS). Neonatal opioid withdrawal syndrome (NOWS) is a newer term describing the subset of NAS related to opioid exposure. Non-pharmacological care is the first-line treatment for substance withdrawal in newborns. Despite the widespread use of non-pharmacological care to mitigate symptoms of NAS, there is not an established definition of, and standard for, non-pharmacological care practices in this population. Evaluation of safety and efficacy of non-pharmacological practices could provide clear guidance for clinical practice. OBJECTIVES To evaluate the safety and efficacy of non-pharmacological treatment of infants at risk for, or having symptoms consistent with, opioid withdrawal on the length of hospitalization and use of pharmacological treatment for symptom management. Comparison 1: in infants at risk for, or having early symptoms consistent with, opioid withdrawal, does non-pharmacological treatment reduce the length of hospitalization and use of pharmacological treatment? Comparison 2: in infants receiving pharmacological treatment for symptoms consistent with opioid withdrawal, does concurrent non-pharmacological treatment reduce duration of pharmacological treatment, maximum and cumulative doses of opioid medication, and length of hospitalization? SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search CENTRAL (2019, Issue 10); Ovid MEDLINE; and CINAHL on 11 October 2019. We also searched clinical trials databases and the reference lists of retrieved articles for randomized controlled trials (RCTs), quasi-RCTs, and cluster trials. SELECTION CRITERIA We included trials comparing single or bundled non-pharmacological interventions to no non-pharmacological treatment or different single or bundled non-pharmacological interventions. We assessed non-pharmacological interventions independently and in combination based on sufficient similarity in population, intervention, and comparison groups studied. We categorized non-pharmacological interventions as: modifying environmental stimulation, feeding practices, and support of the mother-infant dyad. We presented non-randomized studies identified in the search process narratively. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We used the GRADE approach to assess the certainty of evidence. Primary outcomes in infants at risk for, or having early symptoms consistent with, opioid withdrawal included length of hospitalization and pharmacological treatment with one or more doses of opioid or sedative medication. Primary outcomes in infants receiving opioid treatment for symptoms consistent with opioid withdrawal included length of hospitalization, length of pharmacological treatment with opioid or sedative medication, and maximum and cumulative doses of opioid medication. MAIN RESULTS We identified six RCTs (353 infants) in which infants at risk for, or having symptoms consistent with, opioid withdrawal participated between 1975 and 2018. We identified no RCTs in which infants receiving opioid treatment for symptoms consistent with opioid withdrawal participated. The certainty of evidence for all outcomes was very low to low. We also identified and excluded 34 non-randomized studies published between 2005 and 2018, including 29 in which infants at risk for, or having symptoms consistent with, opioid withdrawal participated and five in which infants receiving opioid treatment for symptoms consistent with opioid withdrawal participated. We identified seven preregistered interventional clinical trials that may qualify for inclusion at review update when complete. Of the six RCTs, four studies assessed modifying environmental stimulation in the form of a mechanical rocking bed, prone positioning, non-oscillating waterbed, or a low-stimulation nursery; one study assessed feeding practices (comparing 24 kcal/oz to 20 kcal/oz formula); and one study assessed support of the maternal-infant dyad (tailored breastfeeding support). There was no evidence of a difference in length of hospitalization in the one study that assessed modifying environmental stimulation (mean difference [MD) -1 day, 95% confidence interval [CI) -2.82 to 0.82; 30 infants; very low-certainty evidence) and the one study of support of the maternal-infant dyad (MD -8.9 days, 95% CI -19.84 to 2.04; 14 infants; very low-certainty evidence). No studies of feeding practices evaluated the length of hospitalization. There was no evidence of a difference in use of pharmacological treatment in three studies of modifying environmental stimulation (typical risk ratio [RR) 1.00, 95% CI 0.86 to 1.16; 92 infants; low-certainty evidence), one study of feeding practices (RR 0.92, 95% CI 0.63 to 1.33; 49 infants; very low-certainty evidence), and one study of support of the maternal-infant dyad (RR 0.50, 95% CI 0.13 to 1.90; 14 infants; very low-certainty evidence). Reported secondary outcomes included neonatal intensive care unit (NICU) admission, days to regain birth weight, and weight nadir. One study of support of the maternal-infant dyad reported NICU admission (RR 0.50, 95% CI 0.13 to 1.90; 14 infants; very low-certainty evidence). One study of feeding practices reported days to regain birth weight (MD 1.10 days, 95% CI 2.76 to 0.56; 46 infants; very low-certainty evidence). One study that assessed modifying environmental stimulation reported weight nadir (MD -0.28, 95% CI -1.15 to 0.59; 194 infants; very low-certainty evidence) and one study of feeding practices reported weight nadir (MD -0.8, 95% CI -2.24 to 0.64; 46 infants; very low-certainty evidence). AUTHORS' CONCLUSIONS We are uncertain whether non-pharmacological care for opioid withdrawal in newborns affects important clinical outcomes including length of hospitalization and use of pharmacological treatment based on the six included studies. The outcomes identified for this review were of very low- to low-certainty evidence. Combined analysis was limited by heterogeneity in study design and intervention definitions as well as the number of studies. Many prespecified outcomes were not reported. Although caregivers are encouraged by experts to optimize non-pharmacological care for opioid withdrawal in newborns prior to initiating pharmacological care, we do not have sufficient evidence to inform specific clinical practices. Larger well-designed studies are needed to determine the effect of non-pharmacological care for opioid withdrawal in newborns.

Abstract
BACKGROUND The prevalence of opiate use among pregnant women can range from 1% to 2% to as high as 21%. Just in the United States alone, among pregnant women with hospital delivery, a fourfold increase in opioid use is reported from 1999 to 2014 (Haight 2018). Heroin crosses the placenta, and pregnant, opiate-dependent women experience a six-fold increase in maternal obstetric complications such as low birth weight, toxaemia, third trimester bleeding, malpresentation, puerperal morbidity, fetal distress and meconium aspiration. Neonatal complications include narcotic withdrawal, postnatal growth deficiency, microcephaly, neuro-behavioural problems, increased neonatal mortality and a 74-fold increase in sudden infant death syndrome. This is an updated version of the original Cochrane Review first published in 2008 and last updated in 2013. OBJECTIVES To assess the effectiveness of any maintenance treatment alone or in combination with a psychosocial intervention compared to no intervention, other pharmacological intervention or psychosocial interventions alone for child health status, neonatal mortality, retaining pregnant women in treatment, and reducing the use of substances. SEARCH METHODS We updated our searches of the following databases to February 2020: the Cochrane Drugs and Alcohol Group Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, and Web of Science. We also searched two trials registers and checked the reference lists of included studies for further references to relevant randomised controlled trials (RCTs). SELECTION CRITERIA Randomised controlled trials which assessed the efficacy of any pharmacological maintenance treatment for opiate-dependent pregnant women. DATA COLLECTION AND ANALYSIS We used the standard methodological procedures expected by Cochrane. MAIN RESULTS We found four trials with 271 pregnant women. Three compared methadone with buprenorphine and one methadone with oral slow-release morphine. Three out of four studies had adequate allocation concealment and were double-blind. The major flaw in the included studies was attrition bias: three out of four had a high dropout rate (30% to 40%), and this was unbalanced between groups. Methadone versus buprenorphine: There was probably no evidence of a difference in the dropout rate from treatment (risk ratio (RR) 0.66, 95% confidence interval (CI) 0.37 to 1.20, three studies, 223 participants, moderate-quality evidence). There may be no evidence of a difference in the use of primary substances between methadone and buprenorphine (RR 1.81, 95% CI 0.70 to 4.68, two studies, 151 participants, low-quality evidence). Birth weight may be higher in the buprenorphine group in the two trials that reported data MD;-530.00 g, 95%CI -662.78 to -397.22 (one study, 19 particpants) and MD: -215.00 g, 95%CI -238.93 to -191.07 (one study, 131 participants) although the results could not be pooled due to very high heterogeneity (very low-quality of evidence). The third study reported that there was no evidence of a difference. We found there may be no evidence of a difference in the APGAR score (MD: 0.00, 95% CI -0.03 to 0.03, two studies,163 participants, low-quality evidence). Many measures were used in the studies to assess neonatal abstinence syndrome. The number of newborns treated for neonatal abstinence syndrome, which is the most critical outcome, may not differ between groups (RR 1.19, 95% CI 0.87 to1.63, three studies, 166 participants, low-quality evidence). Only one study which compared methadone with buprenorphine reported side effects. We found there may be no evidence of a difference in the number of mothers with serious adverse events (AEs) (RR 1.69, 95% CI 0.75 to 3.83, 175 participants, low-quality evidence) and we found there may be no difference in the numbers of newborns with serious AEs (RR 4.77, 95% CI 0.59, 38.49,131 participants, low-quality evidence). Methadone versus slow-release morphine: There were no dropouts in either treatment group. Oral slow-release morphine may be superior to methadone for abstinence from heroin use during pregnancy (RR 2.40, 95% CI 1.00 to 5.77, one study, 48 participants, low-quality evidence). In the comparison between methadone and slow-release morphine, no side effects were reported for the mother. In contrast, one child in the methadone group had central apnoea, and one child in the morphine group had obstructive apnoea (low-quality evidence). AUTHORS' CONCLUSIONS Methadone and buprenorphine may be similar in efficacy and safety for the treatment of opioid-dependent pregnant women and their babies. There is not enough evidence to make conclusions for the comparison between methadone and slow-release morphine. Overall, the body of evidence is too small to make firm conclusions about the equivalence of the treatments compared. There is still a need for randomised controlled trials of adequate sample size comparing different maintenance treatments.

Abstract
BACKGROUND A number of recent studies have investigated the optimal dosage and timing of dexamethasone in total hip arthroplasty (THA) but have inconsistent findings. Therefore, we designed the randomized controlled research to look for the optimal intravenous dexamethasone dose for the treatment of early postoperative pain after the THA. METHODS The Declaration of Helsinki principles was followed and the Consolidated Standards of Reporting Trials guidelines for randomized controlled trials was adhered in this study. The First Medical Center in People's Liberation Army General Hospital approved the study (2020-089). After written informed consent was obtained, patients aged between 18 and 80 years with Physical Status I to III of American Society of Anesthesiologists, scheduled for primary unilateral THA, were included in this present work. Randomization is the use of a computer-formed list via a secretary, at a ratio of 1:1:1. The major end points were pain scores at 24 hours, 48 hours, and 72 hours after surgery, with visual analog scale (VAS) utilized at rest, and at 45 degrees passive hip flexion. The secondary outcomes involved the total consumption of morphine, opioid-related side effects, hip range of motion, inflammation markers, and the length of hospital stay. RESULTS We assumed that the patients who received 3 doses of dexamethasone intravenously possessed the best postoperative results compared to those who received 1 or 2 doses of the dexamethasone. TRIAL REGISTRATION This study protocol was registered in Research Registry (researchregistry5864).

Abstract
Background: The goals of the study were to: (1) evaluate trends in preoperative and prolonged postoperative narcotic use in carpal tunnel release (CTR); (2) characterize risks for prolonged narcotic use; and (3) evaluate narcotic use as an independent risk factor for complications following CTR. Methods: A query of a large insurance database from 2007-2016 was conducted. Patients undergoing open or endoscopic CTR were included. Revision surgeries or patients undergoing median nerve repair at the forearm, upper extremity fasciotomies, or with distal radius fractures were excluded. Preoperative use was defined as narcotic use between 1 to 4 months prior to CTR. A narcotic prescription between 1 and 4 months after surgery was considered prolonged postoperative use. Demographics, comorbidities, and other risk factors for prolonged postoperative use were assessed using a regression analysis. Subgroup analysis was performed according to the number of preoperative narcotic prescriptions. Narcotic use as a risk factor for complications, including chronic regional pain syndrome (CRPS) and revision CTR, was assessed. Results: In total, 66 077 patients were included. A decrease in prescribing of perioperative narcotics was noted. Risk factors for prolonged narcotic use included preoperative narcotic use, drug and substance use, lumbago, and depression. Preoperative narcotics were associated with increased emergency room visits, readmissions, CRPS, and infection. Prolonged postoperative narcotic use was linked to CRPS and revision surgery. Conclusions: Preoperative narcotic use is strongly associated with prolonged postoperative use. Both preoperative and prolonged postoperative prescriptions narcotic use correlated with increased risk of complications. Preoperative narcotic use is associated with a higher risk of postoperative CRPS.

Abstract
AIMS Morphine is shown to relieve chronic breathlessness in chronic obstructive pulmonary disease. There are no definitive data in people with heart failure. We aimed to determine the effectiveness and cost-effectiveness of 12 weeks morphine therapy for the relief of chronic breathlessness in people with chronic heart failure compared with placebo. METHODS AND RESULTS Parallel group, double-blind, randomized, placebo-controlled, phase III trial of 20 mg daily oral modified release morphine was conducted in 13 sites in England and Scotland: hospital/community cardiology or palliative care outpatients. The primary analysis compared between-group numerical rating scale average breathlessness/24 hours at week 4 using a covariance pattern linear mixed model. Secondary outcomes included treatment-emergent harms (worse or new). The trial closed early due to slow recruitment, randomizing 45 participants [average age 72 (range 39-89) years; 84% men; 98% New York Heart Association class III]. For the primary analysis, the adjusted mean difference was 0.26 (95% confidence interval, -0.86 to 1.37) in favour of placebo. All other breathlessness measures improved in both groups (week 4 change-from-baseline) but by more in those assigned to morphine. Neither group was excessively drowsy at baseline or week 4. There were no between-group differences in quality of life (Kansas) or cognition (Montreal) at any time point. There was no exercise-related desaturation and no change between baseline and week 4 in either group. There was no change in vital signs at week 4. The natriuretic peptide measures fell in both groups but by more in the morphine group [morphine 2169 (1092, 3851) pg/mL vs. placebo 2851 (1694, 5437)] pg/mL. There was no excess serious adverse events in the morphine group. Treatment-emergent harms during the first week were more common in the morphine group; all apart from 1 were ≤ grade 2. CONCLUSIONS We could not answer our primary objectives due to inadequate power. However, we provide novel placebo-controlled medium-term benefit and safety data useful for clinical practice and future trial design. Morphine should only be prescribed in this population when other measures are unhelpful and with early management of side effects.

Abstract
BACKGROUND The United States is experiencing a continuing crisis of gun violence, and economically marginalized and racially segregated inner-city areas are among the most affected. To decrease this violence, public health interventions must engage with the complex social factors and structural drivers-especially with regard to the clandestine sale of narcotics-that have turned the neighborhood streets of specific vulnerable subgroups into concrete killing fields. Here we present a mixed-methods ethnographic and epidemiological assessment of narcotics-driven firearm violence in Philadelphia's impoverished, majority Puerto Rican neighborhoods. METHODS Using an exploratory sequential study design, we formulated hypotheses about ethnic/racial vulnerability to violence, based on half a dozen years of intensive participant-observation ethnographic fieldwork. We subsequently tested them statistically, by combining geo-referenced incidents of narcotics- and firearm-related crime from the Philadelphia police department with census information representing race and poverty levels. We explored the racialized relationships between poverty, narcotics, and violence, melding ethnography, graphing, and Poisson regression. FINDINGS Even controlling for poverty levels, impoverished majority-Puerto Rican areas in Philadelphia are exposed to significantly higher levels of gun violence than majority-white or black neighborhoods. Our mixed methods data suggest that this reflects the unique social position of these neighborhoods as a racial meeting ground in deeply segregated Philadelphia, which has converted them into a retail endpoint for the sale of astronomical levels of narcotics. IMPLICATIONS We document racial/ethnic and economic disparities in exposure to firearm violence and contextualize them ethnographically in the lived experience of community members. The exceptionally concentrated and high-volume retail narcotics trade, and the violence it generates in Philadelphia's poor Puerto Rican neighborhoods, reflect unique structural vulnerability and cultural factors. For most young people in these areas, the narcotics economy is the most readily accessible form of employment and social mobility. The performance of violence is an implicit part of survival in these lucrative, illegal narcotics markets, as well as in the overcrowded jails and prisons through which entry-level sellers cycle chronically. To address the structural drivers of violence, an inner-city Marshall Plan is needed that should include well-funded formal employment programs, gun control, re-training police officers to curb the routinization of brutality, reform of criminal justice to prioritize rehabilitation over punishment, and decriminalization of narcotics possession and low-level sales.

Abstract
BACKGROUND The use of IV narcotic analgesics (IVNA) within the context of vascular procedures is not fully described. We sought to evaluate the burden of IVNA including narcotic analgesia-related adverse drug events (NARADE), associated mortality and hospitalization cost in open and endovascular vascular procedures, and to compare it with nonnarcotic analgesia (IVNNA). METHODS Retrospective cross-sectional study in hospitals participating in Premier database (2009-2015). Logistic regression analysis was implemented to report the risks of NARADE and in-hospital mortality. Negative binomial regression was used to assess length of stay and generalized linear modeling was used to estimate the hospitalization cost. RESULTS A total of 171,473 patients were identified. NARADE occurred in 6.2% of the cohort. NARADE group was similar in gender and race but was slightly older (median age 71 vs. 70; P < 0.001). After risk-adjustment, NARADE risk was higher in patients who received IVNA-alone in carotid and lower extremity revascularization (LER) [OR (odds ratio) (95% confidence interval [CI]): 1.17 (1.02-1.34) and 1.31 (1.14-1.50)] or combined with IVNNA [OR (95% CI): 1.34 (1.13-1.59) and 1.81 (1.54-2.13)], respectively. Patients receiving aortic repair benefited from the use of IVNA + IVNNA [OR (95% CI): 0.82 (0.69-0.98)]. Occurrence of NARADE doubled the LOS, amplified mortality risk and increased cost in all domains. NARADE increased the odds of mortality by 24.3, 6.5 (4.9-8.68) and 16.6 times and added $5,368, $12,737 and $11,349 to the cost of carotid, aortic and LER interventions, respectively. In contrast, IVNNA was not associated with NARADE risk, increased LOS or cost and showed a survival benefit in patients undergoing open aortic repair [aOR (95% CI): 0.52 (0.36-0.75)]. CONCLUSIONS AND RELEVANCE The use of opioid-based narcotics had increased the risk of NARADE, resources utilization and NARADE-related mortality. Yet the use of nonopioid-based analgesic was safe, did not increase the cost and reduced mortality in open AA repair. This entices shifting the paradigm toward exploring nonopioid-based analgesia options in order to replace or minimize opioid requirements.

Abstract
BACKGROUND DATA Little data exists regarding the effect of chronic preoperative tramadol abuse on the clinical outcomes after surgery. Lumbar discectomy is a very common procedure that has a predictably high success rate for relief of radicular pain. In addition, the patient population presenting for this procedure has a high propensity for preoperative narcotic use. PURPOSE The study aims to identify an association between preoperative tramadol abuse and clinical outcome after lumbar discectomy. STUDY DESIGN A descriptive controlled, non-randomized, clinical study. PATIENTS AND METHODS Sixty patients underwent surgery for lumbar disc herniation. They were divided into two groups; control group and tramadol abuse group. Each group included 30 patients. They were operated between 2015 and 2016. Participants were evaluated pre-operatively and post-operatively every three months. Strict history taking regarding preoperative and postoperative pain medication utilization, operative time, hospital stay and complications were assessed. Pain was scored by a VAS for both lower limbs and back pain. The clinical outcomes were compared using the Prolo economic and functional rating scale. RESULTS In Tramadol abuse group, 12 (40%) continued to use tramadol after surgery. Tramadol abuse group showed worse clinical outcome parameters including worse VAS for low back pain and lower limb pain, worse Prolo economic, functional rating scale. In addition, tramadol abuse group showed significantly higher complications rate in the early post-operative and during the follow up period. CONCLUSION Tramadol abuse before lumbar discectomy was found to be associated with continued tramadol abuse after surgery and worse functional outcomes following surgery. Surgeons may want to counsel their patients about the potential for inferior clinical outcomes if narcotics were used before surgery.

Abstract
Opioid use disorder continues to be a significant source of morbidity and mortality in the USA and the world. Pharmacologic treatment with methadone and buprenorphine has been shown to be effective at retaining people in treatment programs, decreasing illicit opioid use, decreasing rates of hepatitis B, and reducing all cause and overdose mortality. Unfortunately, barriers exist in accessing these lifesaving medications: users wishing to start buprenorphine therapy require a waivered provider to prescribe the medication, while some states have no methadone clinics. As such, users looking to wean themselves from opioids or treat their opioid dependence will turn to alternative agents. These agents include using prescription medications, like clonidine or gabapentin, off-label, or over the counter drugs, like loperamide, in supratherapeutic doses. This review provides information on the pharmacology and the toxic effects of pharmacologic agents that are used to treat opioid use disorder. The xenobiotics reviewed in depth include buprenorphine, clonidine, kratom, loperamide, and methadone, with additional information provided on lofexidine, akuamma seeds, kava, and gabapentin.

Abstract
It has been proven that exposure to some drugs even before gestation had transgenerational effects. To investigate the changes which induced by parental morphine exposure before gestation; mainly the anxiety-like behavior, Corticotropin Releasing Factor (CRF) level in the CSF and plasma, CRF Receptor 1 (CRFR1), and the level of protein kinase C (PKC-α) were evaluated in the male offspring. Male and female Wistar rats were exposed to morphine for 21 following days. Ten days after last drug exposure, animals were prepared for mating in 4 distinct groups as follow: drug-naïve female and male (used as control), drug-naïve female and morphine-abstinent male, drug-naïve male and morphine-abstinent female, and morphine abstinent male and female. Offspring were subjected to assess anxiety-like behavior (using elevated plus maze test). CSF and plasma were gathered, and the CRF level was evaluated by ELISA. Using real-time PCR, the CRFR1 level in the brain was evaluated. Results showed that anxiety-like behavior increased in the offspring of morphine-abstinent parent(s) compared with the control group. CRF level in the plasma and CSF also increased in the litter of morphine-abstinent parent(s). CRFR1 mRNA level was upregulated in the brain of offspring with one and/or two morphine-abstinent parent(s). Furthermore, the level of PKC-α was decreased in the brain of offspring which had one and/or two morphine-abstinent parent(s). Taken together, our findings indicated that morphine exposure even before gestation induced transgenerational effects via dysregulation of HPA axis which results in anxiety in the adult male offspring.

Abstract
PURPOSE To compare the effects of morphine and methadone on length of hospital stay (LOS) or treatment (LOT) and adverse effects in infants with neonatal abstinence syndrome (NAS). DESIGN Systematic review. SAMPLE PubMed, Google Scholar, Cochrane library, CINAHL, IPA, American Academy of Pediatrics, and clinicaltrials.gov were systematically searched to identify randomized controlled trials (RCTs) and observational studies. comparing morphine and methadone for NAS. OUTCOMES LOS, LOT, adverse effects. RESULTS One RCT, two cohort studies, and two chart reviews met inclusion criteria. Each had a low risk of bias. LOS ranged from 12.08 to 36 days with morphine and 21 to 44.23 days with methadone. LOT ranged from 7.46 to 22.9 days (morphine) and 13.9 to 38.08 days (methadone). Adverse effects were not reported. Clinical evidence comparing morphine to methadone for NAS treatment is limited and conflicting. A recommendation for one over the other cannot be made based on these outcomes.

Abstract
Repeated pairings of heroin and a context results in Pavlovian associations which manifest as heroin-conditioned appetitive responses and peripheral immunomodulation upon re-exposure to heroin-paired conditioned stimuli (CS). The dorsal hippocampus (DH) plays a key role in the neurocircuitry governing these context-heroin associations. Within the DH, expression of the pro-inflammatory cytokine interleukin-1β (IL-1β) is required for heroin-conditioned peripheral immunomodulation to occur. However, the role of signaling via IL-1 receptor type 1 (IL-1R1) has not been examined. Furthermore, it has not been evaluated whether the involvement of IL-1 in associative learning extends to classically conditioned appetitive behaviors, such as conditioned place preference (CPP). The first set of experiments investigated whether DH IL-1R1 signaling during CS re-exposure modulates heroin-conditioned immunomodulation and heroin-CPP. The second set of experiments employed chemogenetic techniques to examine whether DH astroglial signaling during CS re-exposure alters the same Pavlovian responses. This line of investigation is based on previous research indicating that astrocytes support hippocampal-dependent learning and memory through the expression of IL-1β protein and IL-1R1. Interestingly, IL-1R1 antagonism disrupted heroin-conditioned suppression of peripheral immune parameters but failed to alter heroin-CPP. Similarly, chemogenetic stimulation of Gi-signaling in DH astrocytes attenuated heroin-conditioned peripheral immunomodulation but failed to alter heroin-CPP. Collectively our data show that both IL-1R1 stimulation and astrocyte signaling in the DH are critically involved in the expression of heroin-conditioned immunomodulation but not heroin-CPP. As such these findings strongly suggest hippocampal neuroimmune signaling differentially regulates Pavlovian immunomodulatory and appetitive behaviors.

Abstract
Opioids are highly effective for cancer pain but are associated with multiple adverse effects and risk of addiction. This article provides a synopsis on the management of various opioid-related adverse effects and strategies to minimize aberrant opioid use in patients who have cancer. Many adverse effects can be effectively managed. Some patients on chronic opioid therapy may demonstrate aberrant behaviors suggestive of opioid misuse or diversion. Through intensive education, longitudinal monitoring, early identification, and timely management, clinicians can optimize the risk to benefit ratio to support safe opioid use.

Abstract
Hypertropia, not due to the usual causes and associated with a central nervous system disorder, should be suspected as being a skew deviation (Hertwig-Magendie sign). We describe a new case of this supranuclear disorder, presumably related to cocaine-induced stroke. This disorder was treated by botulinum A toxin (Oculinum) injection into the superior rectus muscle. Follow-up one year later found the vertical deviation resolved.

Abstract
BACKGROUND There is evidence to suggest that liposomal bupivacaine (LB) is an effective component of a multimodal pain regimen for total joint arthroplasty (TJA). Obesity has been associated with chronic pain following TJA. This study assessed whether early postoperative pain is affected by body mass index (BMI), and whether the standard LB dose has similar effects on obese vs nonobese patients. METHODS A retrospective analysis of 2629 primary TJA over a 12-month period was conducted, with LB used in half of this group. Patients were further classified as nonobese (BMI < 30) or obese (BMI ≥ 30). Pain scores and narcotic use were recorded. Independent-sample t-tests were used for continuous variables and chi-squared analyses for categorical variables. A multivariate regression analysis was performed. RESULTS Significantly less narcotic was required on postoperative days (POD) 0 and 1 in patients receiving LB compared to those who did not in both obese and nonobese patient groups. On POD 2, obese and nonobese patients had an increase in narcotic requirement, which was significant in obese patients. A regression analysis found that on POD 0 and POD 1, lack of LB use, obesity, and younger age were independently associated with increased narcotic use. CONCLUSION While narcotic requirement of obese and nonobese patients decreased on POD 0 and POD 1 with initiation of LB at our institution, all patients demonstrated increased narcotic requirement on POD 2 which was statistically and clinically significant in obese patients. Further studies are needed to determine the optimal pain regimen in the growing obese population undergoing TJA.

Abstract
Objective This study identified sociodemographic, substance use, and multiple opioid prescriber and dispenser risk factors among drug overdose decedents in Rhode Island, in response to an increase in overdose deaths (ODs) involving fentanyl. Methods This cross-sectional investigation comprised all ODs reviewed by Rhode Island's Office of the State Medical Examiners (OSME) during January 2012 to March 2014. Data for 536 decedents were abstracted from OSME's charts, death certificates, toxicology reports, and Prescription Monitoring Program (PMP) databases. Decedents whose cause of death involved illicit fentanyl (N = 69) were compared with decedents whose causes of death did not involve fentanyl (other drug decedents; N = 467). Results Illicit-fentanyl decedents were younger than other drug decedents (P = 0.005). While more other-drug decedents than illicit fentanyl decedents had postmortem toxicological evidence of consuming heroin (31.9% vs 19.8%, P < 0.001) and various pharmaceutical substances (P = 0.002-0.027), third party reports indicated more recent heroin use among illicit fentanyl decedents (62.3% vs 45.6%, P = 0.002). Approximately 35% of decedents filled an opioid prescription within 90 days of death; of these, one-third had a mean daily dosage greater than 100 morphine milligram equivalents (MME/day). Most decedents' opioid prescriptions were filled at one to two dispensers (83.9%) and written by one to two prescribers (75.8%). Notably, 29.2% of illicit fentanyl and 10.5% of other drug decedents filled prescriptions for buprenorphine, which is used to treat opioid use disorders. Conclusions Illicit-fentanyl deaths frequently involved other illicit drugs (e.g., cocaine, heroin). The proportion of all decedents acquiring greater than 100 MME/day prescription dosages written and/or filled by few prescribers and dispensers is concerning. To protect patients, prescribers and dispensers should review PMP records and substance abuse history prior to providing opioids.

Abstract
OBJECTIVE Reducing drug-involved driving is a national policy priority, but little is known about the extent to which drivers receive warnings about the impairment potential of their prescribed medications. We used data from the 2013-2014 National Roadside Survey (NRS) to quantify the proportion of drivers who received warnings regarding potentially impairing medications and the association with driving-related risk perceptions. METHOD Drivers randomly selected at 60 sites completed the self-administered survey, which contained questions on their use of prescription medications. RESULTS Overall, 7,405 drivers completed the prescription drug portion of the NRS. Of these, 19.7% reported recent use (within the past 2 days) of a potentially impairing prescription drug, and 78.2% said the drug had been prescribed for their use. Users of prescribed sedatives (85.8%) and narcotics (85.1%) were most likely to report receiving information about potential impairment, compared with only 57.7% and 62.6% of users of prescribed stimulant and antidepressant medications, respectively. Receipt of warnings varied by sex, race/ethnicity, income, geographic region, and time of day. For a majority of drug categories, drivers who reported receiving warnings had significantly higher odds of perceived risk of impaired driving/crash and criminal justice involvement. CONCLUSIONS Most users of prescription medications reported that the drug was prescribed for their use, but not all reported receiving warnings about driving impairment. Our study provides evidence of missed opportunities for information provision on impaired driving, identifies subgroups that may warrant enhanced interventions, and provides preliminary evidence that receipt of impairment warnings is associated with increased perceptions of driving-related risk.

Abstract
BACKGROUND Recent health care policy changes require hospitals and physicians to demonstrate improved quality. In 2012, a prospective database was formed with the Blue Cross and Blue Shield of Michigan to improve quality of care. The purpose of this study was to analyze patient preoperative medication as predictors of outcomes after total joint arthroplasty. METHODS Data were collected on patient's preoperative medications from 2012 to 2015 using a total joint arthroplasty database. Medications were categorized as antiplatelet, antimicrobial, anticoagulant, narcotic, steroid, insulin, or oral diabetes medication. Outcomes included hospital length of stay (LOS), discharge disposition/destination, and 90-day readmission. Univariate and multivariate regression analyses were performed. RESULTS A total of 3959 patients were studied. Eighty percent (3163 patients) were discharged home. The remainder (795) went to an extended-care facility (ECF). Patients discharged to an ECF were taking more medications (1.13 vs 0.80 in total knee arthroplasty; 1.18 vs 0.83 in total hip arthroplasty; P <.001). Patients who were readmitted took more medications (1.0 vs 0.85; P <.01). There were more discharges to an ECF in narcotic, steroid, and diabetes medication users. Patients taking anticoagulants, narcotics, insulin, and antiplatelets had greater readmission rates. There was a significant correlation between the number of medications and an increased LOS. CONCLUSION Patients taking more medications were more frequently discharged to an ECF and had increased LOS and readmission rates. Narcotics and diabetic medications had the greatest influence. Category and quantity of preoperative medications can be used as predictors of outcomes after arthroplasty surgery.

Abstract
BACKGROUND Older adults are susceptible to adverse effects from the concurrent use of medications and alcohol. The aim of this study was to systematically review the prevalence of concurrent use of alcohol and alcohol-interactive (AI) medicines in older adults and associated adverse outcomes. METHODS A systematic search was performed using MEDLINE (PubMed), Embase, Scopus and Web of Science (January 1990 to June 2016), and hand searching references of retrieved articles. Observational studies reporting on the concurrent use of alcohol and AI medicines in the same or overlapping recall periods in older adults were included. Two independent reviewers verified that studies met the inclusion criteria, critically appraised included studies and extracted relevant data. A narrative synthesis is provided. RESULTS Twenty studies, all cross-sectional, were included. Nine studies classified a wide range of medicines as AI using different medication compendia, thus resulting in heterogeneity across studies. Three studies investigated any medication use and eight focused on psychotropic medications. Based on the quality assessment of included studies, the most reliable estimate of concurrent use in older adults ranges between 21 and 35%. The most reliable estimate of concurrent use of psychotropic medications and alcohol ranges between 7.4 and 7.75%. No study examined longitudinal associations with adverse outcomes. Three cross-sectional studies reported on falls with mixed findings, while one study reported on the association between moderate alcohol consumption and adverse drug reactions at hospital admission. CONCLUSIONS While there appears to be a high propensity for alcohol-medication interactions in older adults, there is a lack of consensus regarding what constitutes an AI medication. An explicit list of AI medications needs to be derived and validated prospectively to quantify the magnitude of risk posed by the concurrent use of alcohol for adverse outcomes in older adults. This will allow for risk stratification of older adults at the point of prescribing, and prioritise alcohol screening and brief alcohol interventions in high-risk groups.

Abstract
We report a case of a 48-year-old male patient with "krokodil" drug-related osteonecrosis of both jaws. Patient history included 1.5 years of "krokodil" use, with 8-month drug withdrawal prior to surgery. The patient was HCV positive. On the maxilla, sequestrectomy was performed. On the mandible, sequestrectomy was combined with bone resection. From ramus to ramus, segmental defect was formed, which was not reconstructed with any method. Post-operative follow-up period was 3 years and no disease recurrence was noted. On 3-year post-operative orthopantomogram, newly formed mandibular bone was found. This phenomenon shows that spontaneous bone formation is possible after mandible segmental resection in osteonecrosis patients.

Abstract
Objective To compare the risk for all cause and overdose mortality in people with opioid dependence during and after substitution treatment with methadone or buprenorphine and to characterise trends in risk of mortality after initiation and cessation of treatment.Design Systematic review and meta-analysis.Data sources Medline, Embase, PsycINFO, and LILACS to September 2016.Study selection Prospective or retrospective cohort studies in people with opioid dependence that reported deaths from all causes or overdose during follow-up periods in and out of opioid substitution treatment with methadone or buprenorphine.Data extraction and synthesis Two independent reviewers performed data extraction and assessed study quality. Mortality rates in and out of treatment were jointly combined across methadone or buprenorphine cohorts by using multivariate random effects meta-analysis.Results There were 19 eligible cohorts, following 122 885 people treated with methadone over 1.3-13.9 years and 15 831 people treated with buprenorphine over 1.1-4.5 years. Pooled all cause mortality rates were 11.3 and 36.1 per 1000 person years in and out of methadone treatment (unadjusted out-to-in rate ratio 3.20, 95% confidence interval 2.65 to 3.86) and reduced to 4.3 and 9.5 in and out of buprenorphine treatment (2.20, 1.34 to 3.61). In pooled trend analysis, all cause mortality dropped sharply over the first four weeks of methadone treatment and decreased gradually two weeks after leaving treatment. All cause mortality remained stable during induction and remaining time on buprenorphine treatment. Overdose mortality evolved similarly, with pooled overdose mortality rates of 2.6 and 12.7 per 1000 person years in and out of methadone treatment (unadjusted out-to-in rate ratio 4.80, 2.90 to 7.96) and 1.4 and 4.6 in and out of buprenorphine treatment.Conclusions Retention in methadone and buprenorphine treatment is associated with substantial reductions in the risk for all cause and overdose mortality in people dependent on opioids. The induction phase onto methadone treatment and the time immediately after leaving treatment with both drugs are periods of particularly increased mortality risk, which should be dealt with by both public health and clinical strategies to mitigate such risk. These findings are potentially important, but further research must be conducted to properly account for potential confounding and selection bias in comparisons of mortality risk between opioid substitution treatments, as well as throughout periods in and out of each treatment.

Abstract
OBJECTIVES Twenty-eight states in the U.S have legalized medical marijuana, yet its impacts on severe health consequences such as hospitalizations remain unknown. Meanwhile, the prevalence of opioid pain reliever (OPR) use and outcomes has increased dramatically. Recent studies suggested unintended impacts of legalizing medical marijuana on OPR, but the evidence is still limited. This study examined the associations between state medical marijuana policies and hospitalizations related to marijuana and OPR. METHODS State-level annual administrative records of hospital discharges during 1997-2014 were obtained from the State Inpatient Databases (SID). The outcome variables were rates of hospitalizations involving marijuana dependence or abuse, opioid dependence or abuse, and OPR overdose in 1000 discharges. Linear time-series regressions were used to assess the associations of implementing medical marijuana policies to hospitalizations, controlling for other marijuana- and OPR-related policies, socioeconomic factors, and state and year fixed effects. RESULTS Hospitalizations related to marijuana and OPR increased sharply by 300% on average in all states. Medical marijuana legalization was associated with 23% (p=0.008) and 13% (p=0.025) reductions in hospitalizations related to opioid dependence or abuse and OPR overdose, respectively; lagged effects were observed after policy implementation. The operation of medical marijuana dispensaries had no independent impacts on OPR-related hospitalizations. Medical marijuana polices had no associations with marijuana-related hospitalizations. CONCLUSION Medical marijuana policies were significantly associated with reduced OPR-related hospitalizations but had no associations with marijuana-related hospitalizations. Given the epidemic of problematic use of OPR, future investigation is needed to explore the causal pathways of these findings.

Abstract
BACKGROUND Opioids are increasingly used in the elderly. Side effects differ compared to other analgesics. PURPOSE In this review article, special aspects about using opioids for noncancer pain in older people and in geriatric patients are identified. CURRENT SITUATION So far randomized controlled trials for the indication of and comparison between various opioids have been performed in middle-aged patients and not exclusively in geriatric patients or elderly (> 75 years). Furthermore, the evidence for multimorbid elderly patients with respect to side effects is also very poor. RECOMMENDATIONS The indication for opioid therapy should be narrow. The patient and their caregivers must be provided patient information regarding opioid therapy. The principle "start low, go slow" is highly recommended. To reduce the risk of falls, longer acting opioids should be used and short acting opioids should be avoided. Everyday relevant negative effects on cognition are possible in opioid use and have to be observed. As recommended in the recently published German guideline for long-term use of opioids in noncancer pain a critical check after 3 months and in case of dosing over 120 mg morphine equivalents is advisable, especially for older patients. Liver and kidney function and drug interactions have to be taken into consideration like in every age group.

Abstract
BACKGROUND Our primary objective was to determine the adjusted quantitative associations of clinical predictors with QT prolongation, a defining cause of Torsades de Pointes (TdP). METHODS A retrospective cohort study was performed on consecutive emergency department patients identified by ECG acquisition date, and heart rate corrected QT (QTc) and QRS durations. QTc was modeled as a function of clinical predictors with multiple linear regression. RESULTS 1010 patients were included. The strongest predictors of QTc and their coefficients were: antidysrhythmic (26.1ms, 95% CI 15.6-36.6) and methadone (43.6ms, 95% CI 28.1-59.2) therapies, and genetic long QT syndrome diagnosis (32.6ms, 95% CI -4.7-70.0). The association of QTc with serum potassium was approximated by a two piecewise linear function that differed by sex. For potassium below 3.9mmol/L, QTc increased by 43.0ms (95% CI 26.2-59.7) and 29.5ms (95% CI 19.1-40.0) for every 1mmol/L decrease in potassium in women and men, respectively. TdP occurred in only 4/686 (0.6%) of patients with QTc≥500 and QRS<120, but mortality during the visit including hospitalization was 8.0%. CONCLUSIONS QTc duration is highly sensitive to hypokalemia, particularly in women. Methadone prolongs QTc remarkably compared to other non-cardiologic medicines. QTc>500 with normal QRS often signifies profound illness and substantial mortality risk, though not necessarily imminent TdP.

Abstract
Concern for illicit and restricted drug use in otolaryngology is similar to other surgical specialties with a few notable exceptions. Many illicit drugs are consumed transnasally. Repeated nasal exposure to stimulants or narcotics can cause local tissue destruction that can present as chronic rhinosinusitis or nasoseptal perforation. Further, the Food and Drug Administration has taken a stance against codeine for pediatric patients undergoing adenotonsillectomy. They have identified an increased risk of death postoperatively with these medications. Because codeine has been the most commonly prescribed narcotic, this has shifted the standard practice.

Abstract
The use of doping substances and methods is extensive not only among elite athletes, but also among amateur and recreational athletes. Many types of drugs are used by athletes to enhance performance, to reduce anxiety, to increase muscle mass, to reduce weight or to mask the use of other drugs during testing. However, the abuse of doping substances and methods has been associated with the occurrence of numerous health side-effects. The adverse effects depend on the type of the consumed drug, as well as the amount and duration of intake and the sensitivity of the body, since there is a large inter-individual variability in responses to a drug. Usually the doses used in sports are much higher than those used for therapeutic purposes and the use of several drugs in combination is frequent, leading to higher risk of side-effects. Among biomedical side-effects of doping, the cardiovascular ones are the most deleterious. Myocardial infarction, hyperlipidemia, hypertension, thrombosis, arrythmogenesis, heart failure and sudden cardiac death have been noted following drug abuse. This paper reviews the literature on the adverse cardiovascular effects after abuse of prohibited substances and methods in athletes, aiming to inform physicians, trainers and athletes and to discourage individuals from using drugs during sports.

Abstract
There is unmet need in patients suffering from chronic pain, yet innovation may be impeded by the difficulty of justifying economic value in a field beset by data limitations and methodological variability. A systematic review was conducted to identify and summarise the key areas of variability and limitations in modelling approaches in the economic evaluation of treatments for chronic pain. The results of the literature review were then used to support the development of a fully flexible open-source economic model structure, designed to test structural and data assumptions and act as a reference for future modelling practice. The key model design themes identified from the systematic review included: time horizon; titration and stabilisation; number of treatment lines; choice/ordering of treatment; and the impact of parameter uncertainty (given reliance on expert opinion). Exploratory analyses using the model to compare a hypothetical novel therapy versus morphine as first-line treatments showed cost-effectiveness results to be sensitive to structural and data assumptions. Assumptions about the treatment pathway and choice of time horizon were key model drivers. Our results suggest structural model design and data assumptions may have driven previous cost-effectiveness results and ultimately decisions based on economic value. We therefore conclude that it is vital that future economic models in chronic pain are designed to be fully transparent and hope our open-source code is useful in order to aspire to a common approach to modelling pain that includes robust sensitivity analyses to test structural and parameter uncertainty.

Abstract
AIM: To evaluate pain control in chronic pancreatitis patients who underwent total pancreatectomy with islet cell transplantation or intrathecal narcotic pump infusion.
METHODS: We recognized 13 patients who underwent intrathecal narcotic pump (ITNP) infusion and 57 patients who underwent total pancreatectomy with autologous islet cell transplantation (TP + ICT) for chronic pancreatitis (CP) pain control between 1998 and 2008 at Indiana University Hospital. All patients had already failed multiple other modalities for pain control and the decision to proceed with either intervention was made at the discretion of the patients and their treating physicians. All patients were evaluated retrospectively using a questionnaire inquiring about their pain control (using a 0-10 pain scale), daily narcotic dose usage, and hospital admission days for pain control before each intervention and during their last follow-up.
RESULTS: All 13 ITNP patients and 30 available TP + ICT patients were evaluated. The mean age was approximately 40 years in both groups. The median duration of pain before intervention was 6 years and 7 years in the ITNP and TP + ICT groups, respectively. The median pain score dropped from 8 to 2.5 (on a scale of 0-10) in both groups on their last follow up. The median daily dose of narcotics also decreased from 393 mg equivalent of morphine sulfate to 8 mg in the ITNP group and from 300 mg to 40 mg in the TP + ICT group. No patient had diabetes mellitus (DM) before either procedure whereas 85% of those who underwent pancreatectomy were insulin dependent on their last evaluation despite ICT.
CONCLUSION: ITNP and TP + ICT are comparable for pain control in patients with CP however with high incidence of DM among those who underwent TP + ICT. Prospective comparative studies and longer follow up are needed to better define treatment outcomes.

Abstract
Hyponatremia, defined as a serum sodium <135 mmol/l, is the most common clinical disorder of water and electrolyte balance. Hyponatremia occurs in approximately 15-20% of hospitalized patients and up to 20% of patients in critical condition. It can lead to a wide range of clinical symptoms, from mild to even life-threatening, and is associated with increased mortality and longer duration of hospitalization in patients affected by many different syndromes. The diagnosis and treatment of hyponatremia in patients’ is still a major problem. Hyponatremia is a disorder observed commonly in toxicological practice. It most often occurs in people who abuse alcohol, narcotics - mainly ecstasy, drugs, as well as the so-called water intoxication in athletes and the people who are mentally ill. In view of the complex pathomechanisms and a variety of symptoms observed in poisoned patients, hyponatremia should be considered as one of the reasons and the exponent of the general condition of the patient.
