[PMID: 36781340 DOI: 10.1016/j.jemermed.2022.11.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 09/27/2022] [Accepted: 11/06/2022] [Indexed: 02/13/2023]
Abstract
BACKGROUND Although hyperthermia is described after cocaine intoxication, the two hyperthermic cases discussed were unusual in severity and duration for cocaine alone. Synephrine was found in biological samples of these patients in high concentrations and was suspected to be an adulterant in illicitly obtained drugs. CASE REPORT Two patients presented to a tertiary care university hospital within 2 days of each other after recreational drug use with delayed and protracted hyperthermia. Synephrine was later found in high concentrations in biological samples as an unexpected drug adulterant. The first patient's presentation came with delayed recognition of hyperthermia and implementation of aggressive cooling measures; he entered multisystem organ failure with prolonged intensive care unit stay and significant morbidity. The second patient's hyperthermia was recognized promptly, and she received early, aggressive cooling, including deep sedation and ice water submersion. She left against medical advice from the hospital at her baseline 3 days after presentation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Synephrine is a suspected adulterant that may be associated with profound hyperthermia. Early recognition of drug overdose and working knowledge of common adulterants can facilitate early targeted management, such as aggressive cooling measures, which may prevent morbidity and mortality.

Abstract
Up to 90% of patients on chronic antipsychotic therapy will experience adverse neurologic side effects, with many of these effects attributable to the dopamine-blocking properties of these drugs. Even the newer, “atypical” antipsychotics are increasingly associated with neurologic complications. In the acute care setting, these medications have broad application beyond the management of psychiatric illness. Given the extent of their use, clinicians should be familiar with the spectrum of neurological syndromes that can develop. Some are common, such as akathisia, acute dystonic reaction, tardive dyskinesia, and drug-induced parkinsonism. Others, such as the life-threatening neuroleptic malignant syndrome, are rare yet must be recognized early to affect survival and improve outcome. This discussion highlights 2 idiosyncratic syndromes, acute dystonic reaction and neuroleptic malignant syndrome. The differential diagnosis for both syndromes and their management is discussed.

Abstract
INTRODUCTION Cocaine abuse is a major worldwide health problem. Patients with acute cocaine toxicity presenting to the emergency department may require urgent treatment for tachycardia, dysrhythmia, hypertension, and coronary vasospasm, leading to pathological sequelae such as acute coronary syndrome, stroke, and death. OBJECTIVE The objective of this study is to review the current evidence for pharmacological treatment of cardiovascular toxicity resulting from cocaine abuse. METHODS MEDLINE, PsycINFO, Database of Abstracts of Reviews of Effects (DARE), OpenGrey, Google Scholar, and the Cochrane Library were searched from inception to November 2015. Articles on pharmacological treatment involving human subjects and cocaine were selected and reviewed. Evidence was graded using Oxford Centre for Evidence-Based Medicine guidelines. Treatment recommendations were compared to current American College of Cardiology/American Heart Association guidelines. Special attention was given to adverse drug events or treatment failure. The search resulted in 2376 articles with 120 eligible involving 2358 human subjects. Benzodiazepines and other GABA-active agents: There were five high-quality (CEBM Level I/II) studies, three retrospective (Level III), and 25 case series/reports (Level IV/V) supporting the use of benzodiazepines and other GABA-active agents in 234 subjects with eight treatment failures. Benzodiazepines may not always effectively mitigate tachycardia, hypertension, and vasospasm from cocaine toxicity. Calcium channel blockers: There were seven Level I/II, one Level III, and seven Level IV/V studies involving 107 subjects and one treatment failure. Calcium channel blockers may decrease hypertension and coronary vasospasm, but not necessarily tachycardia. Nitric oxide-mediated vasodilators: There were six Level I/II, one Level III, and 25 Level IV/V studies conducted in 246 subjects with 11 treatment failures and two adverse drug events. Nitroglycerin may lead to severe hypotension and reflex tachycardia. Alpha-adrenoceptor blocking drugs: There were two Level I studies and three case reports. Alpha-1 blockers may improve hypertension and vasospasm, but not tachycardia, although evidence is limited. Alpha-2-adrenoceptor agonists: There were two high-quality studies and one case report detailing the successful use of dexmedetomidine. Beta-blockers and β/α-blockers: There were nine Level I/II, seven Level III, and 34 Level IV/V studies of β-blockers, with 1744 subjects, seven adverse drug events, and three treatment failures. No adverse events were reported for use of combined β/α-blockers such as labetalol and carvedilol, which were effective in attenuating both hypertension and tachycardia. Antipsychotics: Seven Level I/II studies, three Level III studies, and seven Level IV/V case series and reports involving 168 subjects have been published. Antipsychotics may improve agitation and psychosis, but with inconsistent reduction in tachycardia and hypertension and risk of extrapyramidal adverse effects. Other agents: There was only one high level study of morphine, which reversed cocaine-induced coronary vasoconstriction but increased heart rate. Other agents reviewed included lidocaine, sodium bicarbonate, amiodarone, procainamide, propofol, intravenous lipid emulsion, propofol, and ketamine. CONCLUSIONS High-quality evidence for pharmacological treatment of cocaine cardiovascular toxicity is limited but can guide acute management of associated tachycardia, dysrhythmia, hypertension, and coronary vasospasm. Future randomized prospective trials are needed to evaluate new agents and further define optimal treatment of cocaine-toxic patients.

Abstract
The cerebellum is particularly vulnerable to intoxication and poisoning, especially so the cerebellar cortex and Purkinje neurons. In humans, the most common cause of a toxic lesion to the cerebellar circuitry is alcohol related, but the cerebellum is also a main target of drug exposure (such as anticonvulsants, antineoplastics, lithium salts, calcineurin inhibitors), drug abuse and addiction (such as cocaine, heroin, phencyclidine), and environmental toxins (such as mercury, lead, manganese, toluene/benzene derivatives). Although data for the prevalence and incidence of cerebellar lesions related to intoxication and poisoning are still unknown in many cases, clinicians should keep in mind the list of agents that may cause cerebellar deficits, since toxin-induced cerebellar ataxias are not rare in daily practice. Moreover, the patient's status may require immediate therapies when the intoxication is life-threatening.

Abstract
We discuss the case of a 35-year-old woman who presented with thought impoverishment, disorganized behavior, and echolalia. The patient's condition progressed to treatment-refractory catatonia. She was started on oral Coenzyme Q10 after magnetic resonance imaging of the brain showed findings consistent with drug-induced leukoencephalopathy (DIL). Following improvement, she acknowledged cocaine use that suggested a diagnosis of cocaine-induced leukoencephalopathy (CIL). This case report seeks to elucidate radiological and clinical features of DIL.

Abstract
Role of cocaine in influencing blood-brain barrier (BBB) function is still unknown. Available evidences suggest that cocaine administration results in acute hyperthermia and alterations in brain serotonin metabolism. Since hyperthermia is capable to induce the breakdown of the BBB either directly or through altered serotonin metabolism, a possibility exists that cocaine may induce neurotoxicity by causing BBB disruption. This hypothesis is discussed in this review largely based on our own laboratory investigations. Our observations in rats demonstrate that cocaine depending on the dose and routes of administration induces profound hyperthermia, increased plasma and brain serotonin levels leading to BBB breakdown and brain edema formation. Furthermore, cocaine was able to enhance cellular stress as seen by upregulation of heat shock protein (HSP 72 kD) expression and resulted in marked neuronal and glial cell damages at the time of the BBB dysfunction. Taken together, these observations are the first to suggest that cocaine-induced BBB disruption is instrumental in precipitating brain pathology. The possible mechanisms of cocaine-induced BBB breakdown and neurotoxicity are discussed.

Abstract
Critical care physicians are frequently confronted with intoxicated patients who have used street drugs. In the last decade there has been an upward trend in the use of these substances, particularly amongst adolescents and young adults in large urban areas. In excess quantities all street drugs can lead to critical illness. Early and appropriate medical attention by emergency medicine physicians and intensivists can improve outcomes. In this review article we intend to familiarize critical care physicians with the most common street drugs such as amphetamines, ecstasy, cocaine, gamma hydroxybutyrate, opioids, and phencyclidine.

Abstract
The pathogenetic mechanism of neuroleptic malignant syndrome (NMS), a potentially lethal adverse effect of antipsychotics, is not well understood. In addition to acquired risk factors, clinical observations suggest a number of genetic factors predisposing patients to NMS. Recent findings in pharmacogenetics indicate that the genetic polymorphisms for drug-metabolizing enzymes, drug transporters, and possibly drug-targeting molecules, are associated with the interindividual differences in drug responses concerning both efficacy and adverse reactions. Genetic association studies have sought to identify polymorphisms influencing susceptibility to NMS, especially with respect to the dopamine D(2) receptor, serotonin receptor, and cytochrome p450 2D6. While a few candidate polymorphisms were associated with NMS, a large controlled study is needed to attain statistical power. On the other hand, NMS might include heterogeneous conditions with common characteristic symptoms but different causative mechanisms. Further analysis of individuals with identified genetic mutations or polymorphisms should advance our understanding of mechanisms underlying NMS.

Abstract
Rhabdomyolysis is a disorder in which injury to muscle results in leakage of myocyte intracellular contents into the plasma. It has been associated with a tremendous number and diversity of clinical conditions and substances. Several physiological and biochemical mechanisms for this syndrome have been described. The most likely etiology of rhabdomyolysis in patients presenting to the emergency department is ingestion of drugs of abuse, most commonly ethanol, heroin, amphetamines, cocaine, and other sedatives or stimulants. In this article, the association between rhabdomyolysis and drugs of abuse is explored, as well as its diagnosis and treatment.

Abstract
Patients with methamphetamine toxicity are presenting in greater numbers each year to emergency departments (ED) in the US. These patients are frequently agitated, violent, and often require physical and chemical restraint. The incidence and risk of rhabdomyolysis in this subpopulation is unknown. We conducted a 5-year retrospective review of all ED patients who received the final diagnosis of rhabdomyolysis. Patients with toxicology screens positive for methamphetamine were identified, and demographics, laboratory results, resource utilization, disposition, and outcome were compared to the remaining patients. Of the total 367 patients identified, 166 (43%) were toxicology positive for methamphetamine. Methamphetamine patients differed significantly from nonmethamphetamine patients with regard to demographics and hospital utilization. Methamphetamine patients had significantly higher mean initial creatine phosphokinase (CK), 12,439 U/L versus 5,678 U/L (P = 0.02), and lower mean peak CK, 16,827 U/L versus 19,426 U/L (P = 0.03). The development of acute renal failure was not significantly different between the 2 groups. There were 16 total deaths in the study population, 11 from concomitant infection/sepsis. An association between methamphetamine abuse and rhabdomyolysis may exist, and CK should be measured in the ED as a screen for potential muscle injury in this subpopulation. Patients with rhabdomyolysis with an unclear cause should be screened for methamphetamine or other illicit drugs.

Abstract
Previous case reports indicate that cocaine-associated rhabdomyolysis and excited delirium share many similar features, suggesting that they may be different stages of the same syndrome. We tested this hypothesis by comparing data from 150 cases of cocaine-associated rhabdomyolysis reported in the medical literature with data from an autopsy registry for 58 victims of fatal excited delirium and 125 victims of fatal acute cocaine toxicity. Patients with rhabdomyolysis are similar to victims of fatal excited delirium with regard to age; gender; race; route of cocaine administration; the experiencing of excitement, delirium, and hyperthermia; and the absence of seizures. Compared with victims of fatal acute cocaine toxicity, patients with rhabdomyolysis are different with regard to each of these variables. Compared with victims of fatal acute cocaine toxicity, both victims of rhabdomyolysis and fatal excited delirium are more likely to be black, male, and younger; to have administered cocaine by smoking or injection; and to have experienced excitement, delirium, and hyperthermia; they are also less likely to have had seizures. Because cocaine-associated rhabdomyolysis and excited delirium have similar clinical features and risk factors, occur in similar populations of drug users, and can be explained by the same pathophysiologic processes, we conclude that they are different stages of the same syndrome. It appears that this syndrome is caused by changes in dopamine processing induced by chronic and intense use of cocaine rather than by the acute toxic effects of the drug.

Abstract
A 29-year-old man with C6 tetraplegia (ASIA A) using an implanted baclofen pump and intrathecal catheter infusion system for spasticity control developed severe spasticity, hyperthermia, hypotension, rhabdomyolysis, and disseminated intravascular coagulation after catheter disconnection. Tracheal intubation and mechanical ventilation were necessary. Extensive workup for a concurrent infection was negative except for urine cultures. The patient remained febrile for 10 days despite empirical antibiotic trials. Administration of high-dose benzodiazepines was inadequate for spasticity control. Spasticity control and his clinical condition, including body temperature, did not improve until his catheter was surgically replaced and intrathecal baclofen administration was resumed. The pharmacopathology of abrupt baclofen withdrawal and the similarities between this presentation, sepsis, neuroleptic malignant syndrome, and malignant hyperthermia are discussed. High-dose dantrolene was not used; however, based on similarities between this patient's presentation and neuroleptic malignant syndrome, it may have been the drug of choice.

Abstract
Patients infected by the human immunodeficiency virus are predisposed to many infectious and noninfectious complications and often receive a variety of drugs. Furthermore, they seem to have a particular susceptibility to idiosyncratic adverse drug reactions. It is therefore surprising that only a few cases of the neuroleptic malignant syndrome have been described in patients with the acquired immunodeficiency syndrome. A high index of suspicion is required to diagnose the neuroleptic malignant syndrome in these patients, as its usual manifestations, including fever and altered consciousness, are frequently attributed to an underlying infection.

Abstract
A case of acute renal failure due to rhabdomyolysis in a patient who used cocaine on a daily basis is presented. In contrast to many prior reports of renal failure occurring with cocaine-associated rhabdomyolysis, our patient did not use intravenous cocaine and did not have any evidence of trauma, seizure, hypotension, hyperthermia, hyperactivity, or coma. His creatine phosphokinase peaked at 448,000 U/liter. He was treated initially with forced diuresis and i.v. furosemide, but he became oliguric, developed pulmonary edema, and required hemodialysis. He recovered fully after 3 weeks of dialysis. The literature is reviewed in an attempt to delineate a rational approach to evaluating cocaine users at risk for rhabdomyolysis.

Abstract
The incidence of this previously rare disorder, cocaine-associated agitated delirium, appears to have increased drastically within the last 18 months. The underlying neurochemical abnormalities have recently been characterized, but most clinicians have had little experience with management of agitated delirium. The basic clinical and pathological features of this disorder are reviewed, and common pitfalls in diagnosis and management that frequently lead to needless but very expensive litigation are discussed.
