A Comparison of Dexmedetomidine, Moxonidine and Alpha-Methyldopa Effects on Acute, Lethal Cocaine Toxicity

Dexmedetomidine to Treat 3, 4-Methylenedioxymethamphetamine-Induced Agitation in a 13-Month-Old Infant: A Case Report and Literature Review

We report a 13-month-old infant who accidentally ingested a tablet of 3, 4-methylenedioxymethamphetamine (MDMA) and was brought to the emergency department with tachycardia, seizures, mydriasis, and altered mental status. The patient received multiple doses of benzodiazepines to treat the seizures and developed respiratory insufficiency needing intubation. After extubation, the patient developed hyperactivity, myoclonic, and choreoathetoid movements which were unresponsive to benzodiazepines. Dexmedetomidine was started with good response. The patient made a full clinical recovery. This is the first case that illustrates the possibility to treat MDMA-induced agitation with dexmedetomidine in a 13-month-old infant.

Preventative effects of aripiprazole and quetiapine on seizure and lethality in a mice cocaine toxicity model: an experimental study

Objective

To assess the effectiveness of pre-treatment with aripiprazole and quetiapine to prevent acute cocaine toxicity in a mouse model of cocaine toxicity.

Methods

This experimental study included three groups (n = 25 per group) of mice that were intraperitoneally injected with normal saline solution, 10 mg/kg quetiapine or 10 mg/kg aripiprazole 15 min before 105 mg/kg cocaine hydrochloride. When the cocaine administration was completed, researchers blinded to the study groups observed the mice in terms of seizures and death for a further 30 min.

Results

In the cocaine + quetiapine group, the mean ± SE time to the first seizure was 10.80 ± 2.27 min and seizure activity was detected in 18 mice (72%) by the end of the 30 min. In the cocaine + aripiprazole group, the mean ± SE time to the first seizure was 18.10 ± 1.94 min and seizure activity was detected in 15 mice (60%) by the end of the 30 min. When compared with the control group, there was a significant difference between the cocaine + quetiapine and cocaine + aripiprazole groups in terms of seizure activity. Survival time was increased in the cocaine + aripiprazole group compared with the control and cocaine + quetiapine groups.

Conclusion

Quetiapine and aripiprazole pre-treatment reduced seizure activity and delayed the onset of seizures compared with the control group.

Assessment and Management of Toxidromes in the Critical Care Unit

The most important diagnostic factor in uncovering a toxic etiology for delirium or critical illness is the clinician's openness to the possibility of its existence. Therefore, a consulting psychiatrist, already prepared to perform the detail-oriented work of sorting out behavioral manifestations of disease, can be a vital asset at the bedside if also attuned to the role of purposeful, accidental, and iatrogenic exposures in the intensive care unit. This article summarizes the presentation, evaluation, and treatment of toxidromes relevant to the work of acute psychosomatic medicine.

Pain Control in the Presence of Drug Addiction

Drug addiction is present in a significant proportion of the population in the USA and worldwide. Drug addiction can occur with the abuse of many types of substances including cocaine, marijuana, stimulants, alcohol, opioids, and tranquilizers. There is a high likelihood that clinicians will encounter patients with substance abuse disorders on a regular basis with the prevalence of the use of illicit substances and the high rate of abuse of prescription drugs. The use of abuse deterrent formulations of prescription opioid agents, pill counts, and urine drug abuse screenings are all useful strategies. Optimum pain management of patients with addiction in the outpatient and inpatient setting is essential to minimize pain states. Careful selection of medications and appropriate oversight, including drug agreements, can reduce drug-induced impairments, including sleep deficits and diminished physical, social, and sexual functioning. This review, therefore, discusses the prevalence of illicit and prescription drug addiction, the challenges of achieving optimum pain control, and the therapeutic approaches to be considered in this challenging population. More research is warranted to develop improved therapies and routes of treatments for optimum pain relief and to prevent the development of central sensitization, chronic pain, and impaired physical and social functioning in patients with drug addiction.
