REVIEW
Baraa O Tayeb, Anthony Eidelman, Cristy L Eidelman, Ewan D McNicol, Daniel B Carr
BACKGROUND: Topical local anaesthetics provide effective analgesia for patients undergoing numerous superficial procedures, including repair of dermal lacerations. The need for cocaine in topical anaesthetic formulations has been questioned because of concern about adverse effects, thus novel preparations of cocaine-free anaesthetics have been developed. This review was originally published in 2011 and has been updated in 2017. OBJECTIVES: To assess whether benefits of non-invasive topical anaesthetic application occur at the expense of decreased analgesic efficacy...

INTRODUCTION: Levamisole-adulterated cocaine has been implicated in anti-neutrophil cytoplasmic antibody (ANCA) vasculitis. We present a case of spontaneous intraperitoneal hemorrhage, an unexpectedly severe complication of cocaine-related ANCA vasculitis, developing late during hospitalization. CASE REPORT: An adult male with a history of hepatitis C, distant cocaine use, and limited health care presented to a local emergency department (ED) with volume overload, renal failure, hyperkalemia and non-anion gap metabolic acidosis...

BACKGROUND: While cocaine use is an established risk factor for acute cardiovascular complications, associations between cocaine use and markers of cardiac injury outside of acute hospital presentation remain poorly characterized. We leveraged advances in cardiac troponin (cTnI) testing to assess low but clinically meaningful levels of cardiac injury among cocaine users and non-users. METHODS: We conducted a case control study comparing cTnI levels by the presence of cocaine among patients presenting for non-cardiac care in an urban safety net hospital...

Matthew F Lazenka, S Stevens Negus
Modafinil is a low-potency inhibitor of dopamine transporters (DAT) approved clinically to promote wakefulness. In most procedures used for abuse-liability assessment, modafinil produces effects similar to those of abused DAT inhibitors such as cocaine and methylphenidate, although modafinil often shows lower effectiveness. However, modafinil has failed to maintain drug self-administration or produce conditioned place preferences in rats. The low potency and poor solubility of modafinil complicate its delivery by parenteral routes of administration commonly used in rats, and this may contribute toward negative results...

BACKGROUND: Agitated delirium is frequent following acute brain injury, but data are limited in patients with subarachnoid hemorrhage (SAH). We examined incidence, risk factors, and consequences of agitation in these patients in a single-center retrospective study. METHODS: We identified all patients treated with antipsychotics or dexmedetomidine from a prospective observational cohort of patients with spontaneous SAH. Agitation was confirmed by chart review. Outcomes were assessed at 12 months using the modified Rankin Scale (mRS), Telephone Interview for Cognitive Status (TICS), and Lawton IADL (Instrumental Activities of Daily Living) scores...

Adulteration of cocaine with levamisole is common and can induce serious medical complications. Levamisole is an antihelminthic agent originally approved as an immunomodulator in the treatment of autoimmune disorders and as a chemotherapy adjunct. It was withdrawn from the US market in 2000 but is available in veterinary medicine. Cocaine-using patients may present with nonspecific constitutional symptoms, cutaneous eruptions, leukopenia, vasculitis, and organ damage. Skin manifestations may include severe necrosis, especially of the ear lobes...

Cocaine addiction is a common problem in the adolescent and the young adults, pharmacologic interventions to reverse the effects of which do not exist. Neurological complications of cocaine abuse, such as seizures, headache, ischemic or hemorrhagic stroke, or subarachnoid hemorrhage, can be disastrous as a result of uncontrolled vasoconstriction and vasculitic damage. The lone occurrence of subdural hematoma in the absence of any other intracranial hemorrhagic complication is rarely seen in patients of cocaine abuse...

Cocaine abuse is frequent in patients visiting the emergency department. The knowledge of the cardiovascular complications of cocaine is excellent among physicians. However the awareness regarding its abdominal complications, the most important of which include gastroduodenal perforation, bowel ischemia and splenic rupture is less adequate. We report a 58-year-old with cocaine use who presents with upper abdominal pain and a rapidly worsening clinical status. He was found to have atraumatic splenic rupture causing a hemoperitoneum that was managed by intervention radiology guided splenic artery embolization...

Nitrous oxide (N2O), a long-standing anesthetic, is known for its recreational use, and its consumption is on the rise. Several case studies have reported neurological and psychiatric complications of N2O use. To date, however, there has not been a study using standardized diagnostic procedures to assess psychiatric comorbidities in a patient consuming N2O. Here, we report about a 35-year-old male with magnetic resonance imaging confirmed subacute myelopathy induced by N2O consumption, who suffered from comorbid cannabinoid and nicotine dependence as well as abuse of amphetamines, cocaine, lysergic acid diethylamide, and ketamine...

AIM: There have been significant changes in adolescent consumption habits over the past fifteen years. New molecules have been synthesized, new devices created and a number of products have increased in popularity; and as a result clinicians sometimes lack information. We chose to focus on this population because of its vulnerability, as adolescents show low sensitivity to long-term outcomes of their actions and may be easily influenced by peers as regards experimentation of new drugs...

Levamisole, which is used as an adulterated compound of cocaine, is currently being seen year after year in cocaine intoxication. For a few cases in the last decade, necrotic purpura and neutropenia after levamisole/cocaine intoxication have been described in the medical community. Herein, we present an original case of levamisole intoxication of a 40-year-old woman who smoked heroin and cocaine few during a month. She rapidly presented an extensive necrotic purpura of the nose, cheeks and extremities (lower and upper), and immunologic reactions (positive anti-MPO and anti-HNE)...

A rapid, facile, and sensitive assay of cocaine in biological fluids is important to prevent illegal abuse of drugs. A two-step structure-switching aptasensor has been developed for cocaine detection based on evanescent wave optical biosensing platform. In the proposed biosensing platform, two tailored aptamer probes were used to construct the molecular structure switching. In the existence of cocaine, two fragments of cocaine aptamer formed a three-way junction quickly, and the fluorophore group of one fragment was effectively quenched by the quencher group of the other one...

"Bath salts" are synthetic designer drugs that have stimulant properties and are a growing medical concern. The chemical compounds in the mixtures have an affinity for receptors in the brain resulting in a stimulant effect similar to that seen with methamphetamines and cocaine. Although illegal in Canada, these drugs are widely available online with over 20 synthetic drugs marketed as "bath salts" and used increasingly among recreational drug users. Much of the medical literature regarding these drugs comes from emergency medicine case reports, which outline the acute, severe medical, and psychiatric effects of "bath salt" toxicity...

It is reasonable to expect the presence of multiple drugs to present a complicated picture of toxicity. We report a fatal case involving a young man who purchased illicit drugs and knowingly consumed them. After consuming these drugs and going to sleep in his friend's car, he was found unresponsive the next morning with no signs of physical violence. Drugs found in the peripheral blood at autopsy were oxymorphone, methylone and ethanol at concentrations of 0.106, 0.50 and 130 mg/dL, respectively. The levels of oxymorphone and methylone in peripheral blood were comparable to those observed in other reported fatalities...

Abuse of psychostimulants, such as cocaine, has been shown to be closely associated with complications of the lung, such as pulmonary hypertension, edema, increased inflammation, and infection. However, the mechanism by which cocaine mediates impairment of alveolar epithelial barrier integrity that underlies various pulmonary complications has not been well determined. Herein, we investigate the role of cocaine in disrupting the alveolar epithelial barrier function and the associated signaling cascade. Using the combinatorial electric cell-substrate impedance sensing and FITC-dextran permeability assays, we demonstrated cocaine-mediated disruption of the alveolar epithelial barrier, as evidenced by increased epithelial monolayer permeability with a concomitant loss of the tight junction protein zonula occludens-1 (Zo-1) in both mouse primary alveolar epithelial cells and the alveolar epithelial cell line, L2 cells...

It is inexorable that a proportion of patients with systemic arterial hypertension will develop a hypertensive crisis at some point in their lives. The hypertensive crises can be divided in hypertensive patients with emergency or hypertensive emergency, according to the presence or absence of acute end-organ damage. In this review, we discuss the cardiovascular hypertensive emergencies, including acute coronary syndrome, congestive heart failure, aortic dissection and sympathomimetic hypertensive crises (those caused by cocaine use included)...

A sizeable portion of the societal drain from cocaine abuse results from the complications of in utero drug exposure. Because of challenges in using humans and mammalian model organisms as test subjects, much debate remains about the impact of in utero cocaine exposure. Zebrafish offer a number of advantages as a model in longitudinal toxicology studies and are quite sensitive physiologically and behaviorally to cocaine. In this study, we have used zebrafish to model the effects of embryonic pre-exposure to cocaine on development and on subsequent cardiovascular physiology and cocaine-induced conditioned place preference (CPP) in longitudinal adults...

BACKGROUND: Although the recreational use of psychoactive substances is common there is only limited systematic collection of data on acute drug toxicity or hospital presentations, in particular regarding novel psychoactive substances (NPS) that have emerged on the illicit market in the last years. METHODS: We included all cases presenting at the emergency department (ED) of the University Hospital of Basel, Switzerland, between October 2014 and September 2015 with acute toxicity due to self-reported recreational drug use or with symptoms/signs consistent with acute toxicity...
