Abstract
Background National health monitoring agencies have reported the alternative use of morphine sulfate painkiller for maintenance treatment of opioid use disorder (OUD), associated with a potential increase in overdose risk. Objectives This study sought to assess the prevalence of regular and occasional legally prescribed morphine use in patients treated for OUD and compare their characteristics to those of patients receiving conventional opioid maintenance treatment (OMT), buprenorphine or methadone. Then, we assessed the factors associated with opioid overdose risk. Methods Data were extracted from the French national healthcare system database, covering the entire population in 2015. Diagnosis associated with hospital discharge and long-term disease codes were extracted to select the population and identify outcomes and covariates. OUD non-chronic pain patients were divided into regular (≤35 days between dispensing and ≥3 months of continuous treatment duration) morphine users, and occasional users. Their sociodemographic and health characteristics were compared to OMT controls. A multivariate logistic regression model was performed to determine factors associated with opioid overdose. Results In patients treated for OUD, 2,237 (2.2%) morphine users (1,288 regular and 949 occasional), 64,578 (63.7%) buprenorphine and 34,638 (34.1%) methadone controls were included. The prevalence of regular morphine use among patients treated for OUD regularly receiving an opioid was 1.3%. Compared to users who receive morphine regularly, occasional users had an increased risk of overdose [OR = 2.2 (1.5-3.3)], while the risk was reduced in the buprenorphine group [OR = 0.5 (0.4-0.7)] and not significantly different for methadone [OR = 1.0 (0.7-1.4)]. Other overdose risk factors were low-income, comorbidity, i.e., psychiatric conditions, alcohol use disorder or complications related to intravenous drug use, and coprescription with benzodiazepines or pregabalin. These factors were more frequent in morphine groups. Conclusions Patients that were prescribed oral morphine represented a small minority of the treated for OUD. The poorer health condition affected by numerous comorbidities and higher risk of opioid overdose in patients treated with oral morphine compared with OMT controls points toward the need to better supervise the practices of these patients, to strengthen multidisciplinary care and risk reduction measures.

Risk assessment of using off-label morphine sulfate in a population-based retrospective cohort of opioid-dependent patients. Br J Clin Pharmacol 2020; 86:2338-2348. [PMID: 31389036 PMCID: PMC7688539 DOI: 10.1111/bcp.14082] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2018] [Revised: 05/02/2019] [Accepted: 07/19/2019] [Indexed: 01/09/2023] Open
Abstract
AIMS Several addictovigilance studies have described the off-label use of morphine sulfate (MS) for nonchronic pain in opioid use disorder (OUD) patients as an alternative to conventional opioid substitution treatments (OSTs). This study primarily sought to compare the incidence of unintentional opioid-related overdose in the year following the prescription initiation in off-label MS users, compared to OST-maintained patients. METHODS Sequential cohorts of OUD patients who were regularly dispensed MS, buprenorphine, or methadone, between 1 April 2012 and 31 December 2014, were retrospectively identified using the French nationwide healthcare data system. The incidence of overdoses, deaths, doctor shopping, and complications of a viral, bacterial or thrombotic nature, was compared using the Cox regression method. RESULTS Overall, 1075, 20 834 and 9778 OUD patients without chronic-pain were included in the MS, buprenorphine, and methadone cohorts, respectively. Overdose incidence was 3.8 (P < .01 [95% confidence interval (CI): 2.1-6.8]) and 2.0 (P = .02 [95%CI: 1.1-3.6]) higher in the MS cohort vs buprenorphine and methadone, respectively. Death incidence was 9.1 (P < .01 [95%CI: 3.2-25.9]) and 3.9 (P < .01 [95%CI: 1.4-10.7]) higher in the MS cohort vs buprenorphine and methadone, respectively. The incidences of other associated risks were significantly higher in the MS group vs OSTs, except for hepatitis C viral infection and thrombotic complications. CONCLUSION This first French comprehensive nationwide study reveals increasing overdose, death, bacterial infection, abuse and diversion risks when off-label MS is initiated as alternative to OST. These results question the relevance of prescribing MS as a safe opioid maintenance treatment, considering its health risk profile.

Abstract
Background: The United States is currently experiencing a heroin epidemic. Recent reports have demonstrated a three-fold increase in heroin use among Americans since 2007 with a shift in demographics to more women and white Americans. Furthermore, there has been a correlation between the recent opioid epidemic and an increase in heroin abuse. Much has been written about epidemiology and prevention of heroin abuse, but little has been dedicated to the surgical implications, complications, and resource utilization. Discussion: This article focuses on the surgical problems encountered from heroin abuse and how to manage them in a constant effort to improve morbidity and mortality for these heroin abusers.

Abstract
Background: Intracranial abscess collections, though uncommon, are dreaded complications of head trauma, neurosurgical operations, meningitis, and otogenic, mastoid, and paranasal air sinus infections. Combining surgical evacuation with the appropriate antibiotic therapy is the effective treatment for intracranial abscesses. However, literature on surgical treatment is replete with several procedures which, on their own, may not Objectives: To determine the epidemiology and outcomes (of various treatment modalities) of intracranial abscesses in our institution, a major referral center for neurosurgical conditions in the midwestern region of Nigeria. Materials and Methods: This is a retrospective analysis of demographic data as well as indications, treatment modalities, and outcomes of various surgical procedures for evacuation of intracranial abscesses between September 2006 and December 2011. Results: We carried out 40 procedures in 32 (23 male and 9 female) patients with various intracranial abscesses. These represented approximately 5.6% of all operative neurosurgical procedures in our unit since inception. Most abscesses [16, i.e. 50%] occurred in the second decade. In the first decade, there were 7 (22%), and after the age of 30 years, there were 4 (12.5%). The most susceptible single year of life was infancy with 4 (12.5%) cases of intracranial abscesses. None of the infants had features of congenital heart disease. The predisposing factors were mostly otolaryngologic (9) or posttraumatic (6). Most abscesses (41%) were located in the frontal region, and intraparenchymal (i.e. intracerebral or intracerebellar) (50%) lesions were commoner than extradural, subdural, or intraventricular lesions. The commonest procedure performed (50%) was burr hole evacuation. Four patients (12.5% of cases) died. Prognosis appears to worsen with meningitis as the predisposing infection, ventriculitis, multiple abscesses especially in infants, and immunosuppression. Conclusion: The relative rarity of intracranial abscesses and the frequent delays in making the diagnosis render the condition a significant challenge to the clinician. A high index of suspicion, close interaction between the neurosurgeon and infectious disease specialist, with early treatment by adequate abscess drainage and appropriate antimicrobial treatment are important in their management.

Abstract
A 48-year-old man presented to the emergency department with complain of severe neck pain and anterior chest pain. Intermittent fever in the recent 2 days was also noted. There is a track maker over his left side of neck. The laboratory examination showed leukocytosis and high C-reactive protein level. Urine drug screen was positive for opiate. Empirical antibiotic administration was given. Blood culture grew gram-positive cocci in chain, and there was no vegetation found by heart echocardiogram. However, progressive weakness of four limbs was noted, and patient even cannot stand up and walk. The patient also complained of numbness sensation over bilateral hands and legs, and lower abdomen. Acute urine retention occurred. We arranged magnetic resonance imaging survey, which showed evidence of inflammatory process involving the retropharyngeal spaces and epidural spaces from the skull base to the bony level of T5. Epidural inflammatory process resulted in compression of the spinal cord and bilateral neural foramen narrowing. Neurosurgeon was consulted. Operation with laminectomy and posterior fusion with bone graft and internal fixation was done. Culture of epidural abscess and 2 sets of blood culture all yielded methicillin-sensitive Staphylococcus aureus. For epidural abscess, the most common involved spine is lumbar followed by thoracic and cervical spine. Diagnosis and treatment in the drug abusers are still challenging because they lack typical presentation, drug compliance, and adequate follow-up and because it is hard to stop drug abuser habit. Significant improvement of neurological deficit can be expected in most spinal abscess in drug abusers after treatment.

Abstract
Background Infections related to injection drug use are common. Harm reduction strategies such as syringe exchange programs and skin care clinics aim to prevent these infections in injection drug users (IDUs). Syringe exchange programs are currently prohibited by law in Florida. The goal of this study was to estimate the mortality and cost of injection drug use-related bacterial infections over a 12-month period to the county safety-net hospital in Miami, Florida. Additionally, the prevalence of HIV and hepatitis C virus among this cohort of hospitalized IDUs was estimated. Methods and Findings IDUs discharged from Jackson Memorial Hospital were identified using the International Classification of Diseases, Ninth Revision, codes for illicit drug abuse and endocarditis, bacteremia or sepsis, osteomyelitis and skin and soft tissue infections (SSTIs). 349 IDUs were identified for chart abstraction and 92% were either uninsured or had publicly funded insurance. SSTIs, the most common infection, were reported in 64% of IDUs. HIV seroprevalence was 17%. Seventeen patients (4.9%) died during their hospitalization. The total cost for treatment for injection drug use-related infections to Jackson Memorial Hospital over the 12-month period was $11.4 million. Conclusions Injection drug use-related bacterial infections represent a significant morbidity for IDUs in Miami-Dade County and a substantial financial cost to the county hospital. Strategies aimed at reducing risk of infections associated with injection drug use could decrease morbidity and the cost associated with these common, yet preventable infections.

Abstract
Background Fusobacterium nucleatum is a strict anaerobic microorganism that causes disease entities such as periodontal and soft tissue abscesses, pulmonary and intraabdominal infections and very rarely intracerebral infections. Case presentation Here, we report the rare case of a previously healthy 25-year-old German man with a cerebellar abscess caused by Fusobacterium nucleatum that resulted in rapid brain death. Toxicological screening showed positivity for amphetamines and cannabis. The diagnosis was obtained by polymerase chain reaction amplification of bacterial deoxyribonucleic acid in cerebrospinal fluid. Conclusions In drug users clinicians should think about rare causes of brain abscesses/meningitis. Early diagnosis is necessary and justifies the use of molecular techniques.

Abstract
Illegal addictive drugs can lead to functional or structural impairment of the central nervous system. This review provides an overview of the structural imaging findings on CT, MR imaging, and conventional angiography related to chronic and acute abuse of the most commonly abused illegal drugs, including cannabis, organic solvents, and amphetamines and opioids and their respective derivatives. Pathomechanisms include excitotoxicity, which may lead to an acute or subacute leukoencephalopathy, and vascular complications, including vasoconstriction, vasculitis, or hypertension, which may lead to intracranial hemorrhage or ischemia. Because clinical findings alone are often nonspecific, and afflicted patients are unlikely to admit to the substance abuse, the neuroradiologist may play an important role in establishing the diagnosis and, thereby, initiating treatment.

Use of these drugs may result in a diverse array of acute and chronic complications involving almost any body organ, and imaging frequently plays a vital role in detection and characterization of such complications. The nature of the complications depends to a large extent on the drug used, the method of administration, and the impurities associated with the drug. Radiologically demonstrable sequelae may be seen after use of opiates, cocaine, amphetamines and their derivatives such as 3,4-methylenedioxymethamphetamine ("ecstasy"), marijuana, and inhaled volatile agents including amyl nitrite ("poppers") and industrial solvents such as toluene. Cardiovascular complications include myocardial infarction, cardiomyopathy, arterial dissection, false and mycotic aneurysms, venous thromboembolic disease, and septic thrombophlebitis. Respiratory complications may involve the upper airways, lung parenchyma, pulmonary vasculature, and pleural space. Neurologic complications are most commonly due to the cerebrovascular effects of illicit drugs. Musculoskeletal complications are dominated by soft-tissue, bone, and joint infections caused by intravenous drug use. Awareness of the imaging features of recreational drug abuse is important for the radiologist because the underlying cause may not be known at presentation and because complications affecting different body systems may coexist. Intravenous drug abuse in particular should be regarded as a multisystem disease with vascular and infective complications affecting many parts of the body, often synchronously. Discovery of one complication should prompt the radiologist to search for coexisting pathologic conditions, which may alter management.

Abstract
The central nervous system is one of the primary targets for the detrimental effects of drugs of abuse. Diagnostic imaging, especially MRI, plays an important role in the detection of complications associated with drug abuse. We present the imaging findings associated with the abuse of opioids and other morphine derivatives, as well, as solvents. Of the morphine derivatives, heroin is the most commonly abused. Several CNS pathologic effects have been described in association with its abuse. These include neurovascular complications such as microvascular ischemic changes or ischemic stroke. A rare form of leukoencephalopathy has been described in those abusers who inhale heroin vapors. Other neurologic complications include atrophy and various infectious processes. Solvent inhalation is a common practice among adolescents and young adults secondary to its ease of access and low cost. The most important component of industrial solvents is toluene. Complications of toluene abuse may be either acute, showing no neuroradiological changes, or chronic, characterized by cerebral and cerebellar demyelination as well as atrophy.

Abstract
There are three main, naturally occurring, epidemiological types of botulism: food-borne, intestinal colonization (infant botulism) and wound botulism. The neurological signs and symptoms are the same for all three epidemiological types and may include respiratory paralysis. Wound botulism is caused by growth of cells and release of toxin in vivo, is associated with traumatic wounds and abscesses and has been reported in drug users, such as those injecting heroin or sniffing cocaine. Up to the end of 1999 there were no confirmed cases of wound botulism in the UK. Between the beginning of 2000 and the end of December 2002, there were 33 clinically diagnosed cases of wound botulism in the UK and Ireland. All cases had injected heroin into muscle or by 'skin popping'. The clinical diagnosis was confirmed by laboratory tests in 20 of these cases. Eighteen cases were caused by type A toxin and two by type B toxin.

Abstract
We review the evaluation and treatment of patients with drug addictions complicated by other acute or chronic diseases from the perspective of the hospital setting. The spectrum of drug addiction's complications is broad and in many instances it is predetermined by the abuse substance and its administration route. Some complications of intravenous drug addiction have dramatically decreased in the last few years as a result of a better knowledge of hygienic customs and after the implementation of some health interventions such as the provision of sterile injectable devices. Two highly prevalent infections --HIV/AIDS and hepatitis C-- remain from the period in which most HIV infections owed to the intravenous use of heroin. Of note, these two infections largely account for the survival and quality of life of those who quit their addiction. On the other hand, it is still common the hospitalization of patients with both alcohol dependence and intercurrent diseases in whom their drug addiction may pass unnoticed. Other common situations include the treatment of acute patients with cocaine addiction and psychiatric comorbidity, patients under methadone therapy and, in general, all those cases in which, in emergency, ordinary hospital wards and specialized units, a wide differential diagnosis is raised when there is a coexistence of signs and symptoms common to an addiction, infection and/or intoxication. An integral vision of drug addiction and its complications, as well as the clinical evaluation of all health problems, is fundamental for the prognosis and treatment of these patients.

Abstract
Several bacteria of the Clostridium genus (C. botulinum) produce 150 kDa di-chainal protein toxins referred as botulinum neurotoxins or BoNTs. They associate with non-toxic companion proteins and form a complex termed botulinum toxin or BoTx. The latter is used in clinic for therapeutic purpose. BoNTs affect cholinergic nerve terminals in periphery where they block acetylcholine release, thereby causing dysautonomia and motorparalysis (i.e. botulism). The cellular action of BoNTs can be depicted according to a three steps model: binding, internalisation and intraneuronal action. The toxins heavy chain mediates binding to specific receptors followed by endocytotic internalisation of BoNT/receptor complex. BoNT receptors may comprise gangliosides and synaptic vesicle-associated proteins as synaptotagmins. Vesicle recycling induces BoNT internalisation. Upon acidification of vesicles, the light chain of the neurotoxin is translocated into the cytosol. Here, this zinc-endopeptidase cleaves one or two among three synaptic proteins (VAMP-synaptobrevin, SNAP25, and syntaxin). As the three protein targets of BoNT play major role in fusion of synaptic vesicles at the release sites, their cleavage is followed by blockage of neurotransmitter exocytosis. The duration of the paralytic effect of the BoNTs is determined by 1) the turnover of their protein target; 2) the time-life of the toxin light chain in the cytosol, and 3) the sprouting of new nerve-endings that are retracted when the poisoned nerve terminal had recovered its full functionality.
